1. Introduction<br />
The presence of collective intelligence has been felt for a long time: families, companies and states are<br />
groups of individuals that at least sometimes act intelligent. Bee and ant colonies are examples of groups of insects<br />
that are finding food sources acting intelligent. Even the human brain could be seen as a collection of individual<br />
neurons that collectively act intelligent. In the last few years there have been shown up new examples of collective<br />
intelligence: Google and Wikipedia. Google takes the collective knowledge created by millions of people for making<br />
web<strong>si</strong>tes, u<strong>si</strong>ng sophisticated algorithms and technologies to answer the questions typed in. Wikipedia uses less<br />
sophisticated technologies, but very clever organizational principles and motivational techniques, to get people from<br />
all over the world to create a collection of knowledge.<br />
Mathematic, a measure applied is the “collective intelligence quotient”, which can be ea<strong>si</strong>er formalized than<br />
the individual intelligence quotient. Individual intelligence has been evaluated based on external results of behavior<br />
during real processes or during IQ tests, while elements of collective intelligence, like displacements, actions of<br />
beings or exchange of information, can be observed, measured and evaluated. Szuba (2000, pp. 2) has proposed a<br />
formal molecular model of computation and mathematical logic for describing the collective intelligence concept.<br />
The process, random and distributed, is tested in mathematical logics by social structure. Humans, ant and bacterial<br />
colonies, and information are modeled as abstract informational molecules that have expres<strong>si</strong>ons of mathematical<br />
logic. They are displaced qua<strong>si</strong>-chaotically due to interactions with their environments. Their interactions in abstract<br />
computational space create an inference process perceived as “collective intelligence”. The formal definition of<br />
collective intelligence has a set of requirements: informational molecules must emerge in a certain computational<br />
space, which can be software agents, ants, humans or social structures; than interactions must emerge between<br />
computational space, which con<strong>si</strong>sts in the ability to solve specific problems; and the emergence of collective<br />
intelligence determines specific inferences, in a probabilistic perspective. Based on above conditions, three ba<strong>si</strong>c<br />
hypotheses are presented:<br />
• Precedence hypothe<strong>si</strong>s: collective intelligence emerged first, as a result of interacting chemical<br />
molecules on Earth<br />

• Hypothe<strong>si</strong>s of origin: life emerged later, from collectively intelligent actions of stabilization or<br />
development<br />
• Hypothe<strong>si</strong>s on cycles: dependency between life and intelligence (individual or collective) is the result<br />
of a development cycle of evolution.<br />
Heylighen (1999, pp. 1) con<strong>si</strong>ders that collective intelligence can be defined as a group’s ability to solve<br />
more problems than its individuals. In order to overcome the individual cognitive limits and the difficulties of<br />
coordination, a collective mental map can be used. A collective mental map is represented as an external memory<br />
with shared access and it can be formalized as a directed graph. The ba<strong>si</strong>c mechanism of collective mental map<br />
development con<strong>si</strong>sts of averaging the individual preferences, amplifying the weak links through po<strong>si</strong>tive feedback<br />
and integrating specialized sub-networks through divi<strong>si</strong>on of labor. The efficiency of mental problem-solving<br />
depends on the problem representation in the cognitive system. Problem representation can be determined by a set of<br />
problem states, a set of pos<strong>si</strong>ble actions, and “fitness” criterion, a preference function for selecting the adequate<br />
actions that varies with the specific goals and preferences of the agent. Therefore, a mental map represents a highly<br />
selective representation of features relevant to problem-solving and con<strong>si</strong>sts of problem states, actions that lead from<br />
one state to another, and a preference function for determining the best action at any moment. Increa<strong>si</strong>ng problemsolving<br />
ability needs two complementary processes: enlarging the map with additional states and actions, and<br />
improving the preference function. In this <strong>si</strong>tuation, the better collective mental map is, the more ea<strong>si</strong>ly problems<br />
will be solved. Intelligence agents are characterized by the quality of their mental maps, knowledge and<br />
understanding of their environment, capacities for action or goals.<br />
Collective intelligence is trying to offer a new perspective to different phenomena. The concept is trying to<br />
suggest another way of thinking about effectiveness, profitability, teamwork or leadership.<br />
2. About multi-agent systems<br />
Agents and multi-agent systems offer a new pos<strong>si</strong>bility for analyzing, modeling and implementing the<br />
complex systems. Agent-based vi<strong>si</strong>on offers a wide range of tools, techniques and paradigms, with a real potential to<br />
improve the use of informational technologies.<br />
In a dictionary, an agent is defined as “someone or something who acts on behalf of another person or<br />
group”. This type of definition is too common to be con<strong>si</strong>dered operational. But agents have been defined to be<br />
“autonomous, problem-solving computational entities capable of effective operation in dynamic and open<br />
environments”, (Luck, McBurney, Priest, 2003, p. 10). Therefore, agents offer a new and appropriate route to the<br />
development of complex systems, especially in open and dynamic environments.<br />
Multi-agent systems can approach problems with multiple solving methods, multiple structuring<br />
pos<strong>si</strong>bilities or multiple solving entities, like distributed systems. Thus, multi-agent systems have both the advantage<br />
of distributed and competitive solving problems, and the advantage of representing the complex ways of interactions.<br />
Interactions refer to cooperation, coordination and negotiation.<br />
3. Trust and reputation<br />
In this section will be presented a selection of computational trust and reputation models and describe their<br />
main characteristics, but first we need to clarify the notions of trust and reputation. This field is quite recent, but in<br />
the last years there have been proposed interesting models with direct implementation in different domains.<br />
3.1 Trust<br />
Trust is important to human society due to its social component. The concept of trust has different<br />
meanings, but Gambetta’s point of view is the most <strong>si</strong>gnificant:<br />
“ ©��£��”. (Gambetta, 2000, pp. 4)<br />
There are <strong>si</strong>gnificant characteristics of trust mentioned in the above definition:<br />
• Trust is subjective<br />
• Trust is affected by the actions that cannot be monitor<br />
• The level of trust is dependent on how our actions are affected by the other agent’s actions.<br />
�¢§����¢��<br />
��¤�¢£�©¨¨ ��£��¢§���£�©�©¢�£�§¨©¢¨¤�¤¨����¤�§�¡¤��£�¤�¢��©�£¨£� ¡£��¡�£��©�©�¤�� ©��¤��¤���©�©����¤¢©�¤���¢�¢�§���©�¤���¡£¨¨�¤¢��¢�©�©¢�£�§¨©¢©��£��������¤��¢¤�¤�©����£��¢�§�� ©��£����¢£��¤�¤��¤��¨ ���£��©�©�£� ¤�¤¢���¤©�¨¤�����£��¢£��©��£�©����¤��£�¡�£��£�©��¤����£��¡�<br />

From the socio-cognitive perspective of Castelfranchi and Falcone (1998, pp. 2), trust represents an explicit<br />
reason-based and conscious form. While trust means different things, the concept can be seen as:<br />
• A mental attitude towards another agent, a dispo<strong>si</strong>tion<br />
• A deci<strong>si</strong>on to rely upon another agent, an intention to delegate and trust<br />
• A behavior, for example the intentional act of trust and the relation between the trustier and the trustee.<br />
The above concepts imply multiple sets of cognitive elements involved in the trustier mind.<br />
3.2 Reputation<br />
Typologies of trust<br />
In a social manner, there have been identified three types of trust:<br />
• interpersonal trust (the direct trust that an agent has in another agent)<br />
• impersonal trust (the trust within a system that is perceived through different properties)<br />
• dispo<strong>si</strong>tional trust (the general trusting attitude)<br />
An agent behavior can be induced by other agents that cooperate, determining a reputation mechanism. The<br />
<strong>si</strong>mplest definition of reputation can be the opinion others have of us. Otherwise, reputation represents a perception<br />
that an agent has of another agent’s intentions or an expectation about an agent’s behavior.<br />
Abdul-Rahman and Hailes (2000, pp.8) have defined reputation as “an expectation about an agent’s<br />
behavior based on information about or observations of its past behavior.” This definition con<strong>si</strong>ders reputational<br />
information based on agent’s personal experiences.<br />
3.3 Computational Trust and Reputation Models<br />
This field is quite recent, but in the last years new approaches have been proposed, with direct<br />
implementation in different domains, in order to determine the level of trust.<br />
Marsh (1994, pp. 53-68) has introduced a computational trust model in the distributed artificial intelligence.<br />
An artificial agent can absorb the trust and than he can make trust-based deci<strong>si</strong>ons. This model proposes a<br />
representation of trust as a continuous variable over the range [-1, +1). There are differentiated three types of trust:<br />
ba<strong>si</strong>c trust (calculated from all agent’s experiences), general trust (the trust on another agent without taking into<br />
account a specific <strong>si</strong>tuation) and <strong>si</strong>tuational trust (the trust on another agent taking into account a specific <strong>si</strong>tuation).<br />
There are proposed three statistical methods to estimate general trust, each determining a different type of agent: the<br />
maximum method leads to an optimistic agent (takes the maximum trust value from the experiences he has), the<br />
minimum method leads to a pes<strong>si</strong>mistic agent (takes the minimum trust value from the experiences he has) and the<br />
mean method that lead to a realistic agent (takes the mean trust value from the experiences he has). Trust values are<br />
used in agents’ deci<strong>si</strong>on whether to cooperate or not with another agent.<br />
Zacharia (1999, pp. 37-55) has proposed two reputation mechanisms (Sporas and Histos) in online<br />
communities based on collaborative ratings that an agent receives from others. Sporas takes into con<strong>si</strong>deration only<br />
the recent ratings between agents and users with very high reputation values have smaller rating changes after<br />
updates than users with a low reputation. Histos comes as a reply, taking into con<strong>si</strong>deration both direct information<br />
and witness information. The reputation value is subjectively as<strong>si</strong>gned by each individual, so reputation mechanisms<br />
could generate social changes in users’ behavior. A successful mechanism ensures high prediction rates, robustness<br />
against manipulability and cooperation incentives of the online community.<br />
Abdul-Rahman and Hailes (2000, pp. 10-20) have suggested a model that allows agents to decide which<br />
other agents’ opinion they trust more. In their view trust can be observed from two perspectives: as direct trust or as<br />
recommender trust. Direct trust can be represented as one of the values: “very trustworthy”, “trustworthy”,<br />
“untrustworthy” or “very untrustworthy”. For each partner, the agent has a panel with the number of past experiences<br />
in each category, and trust on a partner is given by the degree corresponding to the maximum value in the panel. The<br />
model takes into account only the trust coming from a witness, the recommender trust, which is con<strong>si</strong>dered<br />
“reputation”. This approach could not differentiate agents that are lying from those that are telling the truth, but think<br />
different, so the model gives more importance to the information coming from agents with <strong>si</strong>milar point of view.<br />
Sabater and Sierra (2001, pp. 1-5) have proposed a modular trust and reputation model (ReGreT) to ecommerce<br />
environment. This model takes into con<strong>si</strong>deration three different types of information sources: direct<br />
experiences, information from third party agents and social structures. Trust can be determined combining direct<br />
experiences with the reputation model. Direct trust is built from direct interactions, u<strong>si</strong>ng information perceived by<br />
the agent itself, and determined trust based on direct experiences. The reputation model is composed of specialized<br />
7
types of reputation: witness reputation (calculated from the reputation coming from witness), neighborhood<br />
reputation (calculated from the information regarding social relations between agents) and system reputation<br />
(calculated from roles and general properties). Witness reputation is calculated based on information from other<br />
agents of the community. Neighborhood reputation is expressed based on social environment of the agent and the<br />
relations between the agent and that environment. System reputation is con<strong>si</strong>dered as objective features of the agent<br />
(for example, agent’s role in the society). Those components merge and determine a trust model based on direct<br />
knowledge and reputation.<br />
4. NetLogo Simulation<br />
Preferential attachment is frequently used in describing social, biological and technological networks and it<br />
represents the mechanism of formation models for such networks. Social networks are interaction networks, where<br />
nodes are agents and links between nodes are interactions between agents. In the evolution of social networks, an<br />
important hypothe<strong>si</strong>s is that highly connected nodes increase their connectivity faster than their less connected peers,<br />
called preferential attachment. Experiments reveal that the rate at which nodes acquire links depends on the node’s<br />
degree, offering direct quantitative support for the presence of preferential attachment.<br />
The evolving network models are mostly based on two important hypothe<strong>si</strong>s, growth and preferential<br />
attachment. The growth hypothe<strong>si</strong>s sustains that networks continuously expand through new nodes and links between<br />
the nodes, and the preferential attachment hypothe<strong>si</strong>s<br />
£.<br />
sustains that the rate with which a node with links acquire a<br />
new link is a monotonically increa<strong>si</strong>ng function of £<br />
4.1 Preferential Attachment in NetLogo<br />
This model shows a way of ari<strong>si</strong>ng networks, when there are a few hubs that have many connections, while<br />
the others have only a few. The model starts with two nodes connected by an edge. A new node is added at each step.<br />
A new node picks an existing node to connect to randomly, but there is a tendency observed: a node’s chance of<br />
being selected is directly proportional to the number of connections it already has. In our <strong>si</strong>mulations, we are going<br />
to endow agents with two attributes, “reputation” and “intelligence”.<br />
Fig. 1 a) Fig. 1 b)<br />
We can observe there are two nodes that have many connections, while the most of them have only a few<br />
(figure 1 b)) shows re<strong>si</strong>zed nodes, for clearance). Experiences have shown that the popular nodes will acquire new<br />
links faster than the other ones (figure 1 a) and figure 1 b)).<br />
4.2 Simulations<br />
The forthcoming <strong>si</strong>mulations will try to show agents’ behavior assuming that they are endowed with two<br />
attributes, reputation and intelligence. We propose a representation of reputation as a variable over the range [-1, 1]<br />
and intelligence as a variable over the range [1, 100].<br />
Figure 2 a) presents the intelligence values for the agents. The maximum intelligence value is 100 and the<br />
minimum intelligence value is 80, but the difference between them is amplified by the growing number of agents.<br />
8
Fig. 2 a)<br />
In figure 2 b) are shown the reputation values, ranging between [-1, 1].<br />
Fig. 2 b)<br />
The first agent’s intelligence is a random value<br />
between 1 and 100. Agents are going to be linked each<br />
other only if their intelligence is varying with less than<br />
10. For example, if an agent has intelligence 92, it could<br />
have connections only with agents that have intelligence<br />
between 82 and 100.<br />
We can notice that agents make links with those<br />
agents that have the closest value of intelligence. For<br />
example, if there are two agents, one with intelligence<br />
92 and the other with intelligence 95, a third agent with<br />
intelligence 87 will choose to connect to the agent with<br />
the closest intelligence, the agent with intelligence 92.<br />
Agent’s reputation is determined by the number of<br />
connections that agent has with other agents. The more<br />
connections an agent has, the reputation value is closer<br />
to 1.<br />
The first agent has frequently reputation value 1<br />
because it is the agent with the higher number of<br />
connections.<br />
Figure 2 c) shows agents endowed with the two attributes, reputation and intelligence.<br />

Fig 2 c)<br />
An agent prefers to connect with another agent that has a high level of reputation, but in the same time with<br />
the closest value of intelligence.<br />
5. Conclu<strong>si</strong>ons<br />
The organizational behavior field is interested in studying organizations as complex social systems. Trust is<br />
a deci<strong>si</strong>ve source of social capital within social systems. Most of the theories from this field explore individual and<br />
collective human behavior within organizations and their central activities try to identify the determinants of intraorganizational<br />
cooperation. Managing collective intelligence within an organization implies combining all tools,<br />
methods and processes that can lead to connection and cooperation among individual intelligences.<br />
Individual intelligence can not face all the problems in today’s world. To successfully deal with problems<br />
we need to develop collective intelligence as a global civilization. Collective intelligence can improve<br />
competitiveness within organizations in the context of a global market and collective performance has become a<br />
critical factor in the organization’s development. In this <strong>si</strong>tuation creating, developing and sustaining trust among<br />
members within teams is the core that leads to performance.<br />

Introduction<br />
Current society, starting from the largest international forums up to a state, organisation, and, somewhat less<br />
obvious, individual level, wishes to embrace ethical goals and actions. At a higher level of understanding, this ethical<br />
dimen<strong>si</strong>on translates into the balance between the three, or, according to other interpretations, four interdependent<br />
pillars of sustainable development – economic, social, environmental, and, pos<strong>si</strong>bly, cultural. The concept of<br />
sustainable development, although apparently labeled as „noble” and „good”, is still confronted with some criticism.<br />
What’s more, despite the wide circulation of the concept, the quality of air, for instance, continues to deteriorate, this<br />
being one of the many examples of environmental deterioration through exces<strong>si</strong>ve exploitation or polution. The<br />
social pillar does not exhibit obvious improvements either.<br />
Suppose an exercise by which we would imagine an account which listed, one one <strong>si</strong>de, the measures and<br />
regulatory processes which sustain this sustainable development, and on the other <strong>si</strong>de the disparate and correlated<br />
actions which have a contrary effect to it (or otherwise put are focus on the accelerated development of one of the<br />
pillars at the base of sustainable development, frequently the economic one, without protecting or even to the<br />
detriment of at least another pillar – usually the environmental one). Despite the parade of values and stated<br />
preoccupation, in letter or in fact, at various levels by key-players or organisations with various branches of activity<br />
and fields of action, the tendency emerging from such an exercise would be of such a nature as to decrease the<br />
credibility in promises of sustainable development or at least raise questions on the effectiveness which which this<br />
goal is pursued.<br />
In long term, the gap between what we know we should be doing and what we are actuallz doing (at the<br />
highest levels) in the sense of sustainable development could have the effect of a bubble, a „speculative scheme<br />
which depends on unstable factors” (according to the definition given by the Laboratory of Cognitive Sciences at the<br />
Univer<strong>si</strong>ty of Princeton), which fundamentally contavenes the concept of „sustainability”. As in the case of any other<br />
bubble, the wager on an entity without substance grows up to the point where a comeback to normal parametres is<br />

equired and where the gap between perception or convention, as depicted by the entity in question, and reality<br />
becomes obvious. In the case of sustainable development, the „entity” under discus<strong>si</strong>on is formed by the very<br />
concept under discus<strong>si</strong>on, or rather by the its nature, still abstact for some factors of decicion.<br />
In order to deepen the understanding of the concept of sustainable development, we seeked to argument<br />
some viewpoints regarding the purpose, the need and the obstacles which it entails.<br />
The purpose of understanding the concept of sustainable development<br />
Ferry stated that “I know that this term is obligatory but I find it also absurd, or rather so vague that it says<br />
nothing" (Ferry, 2007). However, the issue was outlined by various documents and I dare to say that the main<br />
problem is not the lack of understanding on it under he circumstances when the concept appeals to ethical principles<br />
which are widely used and much debated upon. The problem is rather the conflict with the immediate individual<br />
interests, at the level of an individual and an economic entity. The academic debates on the form may yet be an<br />
excuse for not addres<strong>si</strong>ng the substance.<br />
The purpose of pursueing the goal of sustainable development<br />
Another critique put forward by Baden, pre<strong>si</strong>dent of the Foundation for Research on Economy and the<br />
Environment, is that “In economy like in ecology, the interdependence rules applies. Isolated actions are impos<strong>si</strong>ble.<br />
A policy which is not enough carefully thought will carry along various perverse and adverse effects for the ecology<br />
as much as for the economy. Many suggestions to save our environment and to promote a model of 'sustainable<br />
development' risk indeed leading to reverse effects”. By this theory I understand that the effects generated by the<br />
concerns and measures due to approaching an issue are not necessarily the ones expected and , ultimately, “the road<br />
to hell is paved with good intentions”, namely no matter how good intended the intervention is, it can lead to<br />
inhibiting the recovery or accelerating the decline and gradation. The diametrically opposed alternative would be the<br />
complete absence of a concern became, beyond useless, a priory contrary to itself, in favour of continuing and<br />
inten<strong>si</strong>fying an economic activity characterised as “self-consuming”. Again, fear of assuming a po<strong>si</strong>tion and its<br />
derived actions looks like an excuse for avoiding an attitude. By extrapolation, it may be deduced that any action is<br />
associated with the risk of not attaining its aim and at the same time that there is not an acceptable risk level to this<br />
end, therefore it makes no sense to undertake any action. Continuing the discourse, (if yet necessary to promote such<br />
an hypothe<strong>si</strong>s) it may moot the question either of suppres<strong>si</strong>ng any type of action, including the ones involving<br />
surviving (for example food finding and eating) or of maintaining exclu<strong>si</strong>vely those kind of actions assuming<br />
immediate survival (long term survival assumes a thinking and projection process which on its turn involves a level<br />
complex enough to be subjected to the errors and limitations of human thinking, so, as any kind of complex action<br />
runs the risk of betraying its aim). So, it may be drawn the conclu<strong>si</strong>on of human being returning to primate stage and<br />
conscience repres<strong>si</strong>on. Indeed, the adverse effects pos<strong>si</strong>ble to be generated on the environment by this kind of<br />
community would be minimum but a new debate topic would be if it is worth suppres<strong>si</strong>ng conscience and culture,<br />
human civilization aiming at preserving the environment or if the two elements – natural environment and human<br />
civilisation – could not be reconciled.<br />
The purpose of the goal of sustainable development<br />
The third critique comes from the cornucopian paradigm of replacing the natural resource neces<strong>si</strong>ties with<br />
technological solutions. Hotelling, for instance, developed theories of optimal rates of resource exhaustion by which<br />
the pricing game would determine the development of an alternate technology to replace the consumed scarce<br />
resource as this scarce resource is being exhausted, and so its price increases as an effect of scarcity (Hotelling,<br />
1931). Otherwise put, the need is the one guaranteeing creativity so as to ensure permanent stock of resources or<br />
alternatives to these. Indeed, Barnett states that the technological changes are self-generating and inseparable from<br />
the circumstances generating a high demand of traditional resources and finally that there are no limitations of the<br />
economic growth related to resource rareness (Barnett, 1974). In extremis, Ausbel discon<strong>si</strong>ders the environmental<br />
conditions as having a decrea<strong>si</strong>ng relevancy for a population who will live soon under domes (Ausbel, 1991).<br />
However, the appeal to technology as an intervention of “deus ex machina” nature ( that is very appropriate for this<br />
specific <strong>si</strong>tuation) can be characterised as irrespon<strong>si</strong>ble if it is not substantiated on a plan of viable projects.<br />
Moreover, it may be con<strong>si</strong>dered as dangerous to the extent to which it allows the irrever<strong>si</strong>ble change of the living<br />
environment in an artificial one, man made and consequently vulnerable to human errors owed to previ<strong>si</strong>ons and<br />
implementation on the one hand and subject to the human control susceptible of becoming aim of the political<br />
ambitions on the other hand.<br />

The natural environment regulates and coordinates the evolution of species, which are seen as components<br />
to this environment with very specific roles, but can ultimately exclude them from its system. Due to a certain<br />
symmetry, humans pretend to coordinate and use the natural environment con<strong>si</strong>dered as a component of the broader<br />
spectrum of human activity and just on the line they threaten this natural environment with disappearance of some<br />
components and fundamental altering of some other ones. This game of power has sometimes been named “playing<br />
God”.<br />
The natural environment may very well exist (and I dare stress “very well”) in the utter absence of humans.<br />
In exchange, humans depend at least on some components of the natural environment. Firstly the aspect of neces<strong>si</strong>ty<br />
(independence between natural environment and humans and reverse) and then the ethical one will be treated.<br />
The legitimacy of granting to the environment an inclu<strong>si</strong>on and coordination function on the humans is<br />
justified by framing the human species as animal species depending on the environment where it was borne and<br />
developed. Humans, at the present stage of biological and technological development, cannot survive without air<br />
(oxygen implicitly), food (the sources of which, irrespective of the proces<strong>si</strong>ng degree, are also of natural kind) and<br />
water. Oppo<strong>si</strong>tely, in order that humans to assume the role God on nature, they should have the primordial capacity<br />
assumed by this “role” – that of creation – starting (at last) with creating of the means necessary to support the own<br />
life”. However, the efforts assumed by synthe<strong>si</strong><strong>si</strong>ng the fresh air, potable water and animal or vegetal food resources<br />
in the event of their large scale degradation, reduction or even disappearance, exceed the present technology<br />
development stage. If air would disappear or waters would dry mankind would disappear. The scenario is obviously<br />
exaggerated but it shows in the most striking way (if necessary) the human life dependence on the natural<br />
environment. The argument may then be shifted from existence sphere to the quality and health one.<br />
Technology does not have yet the capability to substitute nature. If humans progres<strong>si</strong>vely degrade the<br />
natural environment gambling on a cornucopian stake, they have to develop in parallel a research plan aimed at<br />
synthe<strong>si</strong><strong>si</strong>ng an environment able to support life. However, contrary to sustainability principles, the actual<br />
generation consume and pollute and transmit to the future generations only noxious consequences and the task to<br />
undertake measures, ultimately to undertake the above mentioned research. The risks of creating a human system,<br />
therefore subject to errors and omis<strong>si</strong>ons, the stake of which would be the very survival of the species survival and<br />
either the specific political implications will not be dealt with here. The question remains whether such a endeavour<br />
of substitution, even a fea<strong>si</strong>ble one, would be legitimate from the ethical viewpoint. In another words, humans’ right<br />
to adapt a planet to the unique purpose of serving their need and comfort in the strictest sense – for example to allow<br />
the extinction, due to the conditions they generate, of a species whose products they do not use.<br />
Like in the case of any other academic debate, there are also opinions fundamentally opposed to the<br />
cornucopian one which draw attention on the stringent nature of the scarcity of resources problem and on the need to<br />
implement measures of protecting then, going as far as reduction of consumtion and conditioning human wellfare on<br />
the protection of these resources. 'Vi<strong>si</strong>on' is very popular these days, as befitting the approach of the millennium. The<br />
dust-jacket of the book “Beyond growth: the Economics of sustainable Development” informs us that the author, at<br />
least, is a fully paid-up vi<strong>si</strong>onary, having been named one of a hundred 'vi<strong>si</strong>onaries who could change your life'. He<br />
has certainly been one of the pioneers of the notion that the economics profes<strong>si</strong>on has concentrated too much on the<br />
allocation of resources between competing ends without recognizing that there is a problem of the overall scale of<br />
resource use in a world limited by the fixed <strong>si</strong>ze of our host ecosystem (Daly 1996). Recycling cannot provide an<br />
escape on account of the law of entropy, a fundamental law of the phy<strong>si</strong>cal world that is often a cause of great<br />
concern or excitement among many environmental activists, but which, for practical purposes, merely means that<br />
when you have burnt a piece of coal you don't have it any more. Given the phy<strong>si</strong>cal constraints on growth we need to<br />
aim at a less resource-inten<strong>si</strong>ve life-style in the interests of 'sustainable development' as defined by Daly. His<br />
definition raises various questions, such as how long the human race is expected to survive (affecting the cumulative<br />
population for which the eco-system has to provide).<br />
Sustainable development and economic development<br />
A main idea on the “sustainable society” is found in the definition from the recent speech of Lester Brown,<br />
mostly contained in the paper “Plan B 2.0”, namely the society adjusting the economic and social system so that to<br />
maintain the natural resources and life support systems. However, as Bard noticed such prospectuses are focused on<br />
the sustainable development expressed by ,”increase of the national wealth measured by gross domestic income,<br />
value added sum” (Barde 1997) , and not on the sustainable development itself.<br />
Therefore, can the three conventional pillars of the sustainable development be regarded as being in a<br />
de<strong>si</strong>rable relation of Pareto dynamic equilibrium – where each develops without detriment (or cause contraction) to<br />
the others? John G. Clark delivered a critique on the World Commis<strong>si</strong>on for Environment and development (WCED)<br />
for “encouraging the non-sustainable idea that the economic development and economic growth would be<br />
14
compatible – or, that the economic development actually supports environment sustainability” (Clark 1995). The<br />
author’s the<strong>si</strong>s is that WCED subordinates sustainability to development, underlying the need to integrate<br />
environmental reasons with economic goals and not, for ex., economic reasons with environmental goals. Moreover,<br />
“WCED treated the sustainable development more as a mystic goal than as a concrete objective that could be reached<br />
by concrete actions”. The economic activity has the tendency to assume the main role and the “rest” to be con<strong>si</strong>dered<br />
as background more or less “decorative” form the viewpoint of conscience comfort and public image. As it was<br />
mentioned above when noticing the approaches evolution, at the beginning of the formal concerns this empha<strong>si</strong>s was<br />
obvious under the circumstances when Hirschman, Rostow and Black identified the following prerequi<strong>si</strong>tes of the<br />
sustainable development: availability of the long term development capital, stable industrial labour force,<br />
urbanisation, technological capabilities, entrepreneurship and innovation with an affinity for large scale production<br />
units and commercial agriculture (Hirchman 1958), (Rostow 1971), (Black 1966). In collateral studies, Coleman,<br />
Bendix and Huntington added to his list the democratization, bureaucratization and rationalisation of the political<br />
structures (Coleman 1960), (Bendix 1967), (Huntington 1966). According to Clark’s comments, in order to reach<br />
such prerequi<strong>si</strong>tes the elites of less developed countries would readjust the national institutions, many of them having<br />
colonial origins, in compliance with the American or European institutions image. Once democratised, these elites,<br />
with con<strong>si</strong>derable help from the developed countries, would restructure their economies so that to meet the<br />
requirements of a self-sustained economic growth. In all this action sequence, the environment is <strong>si</strong>mply the<br />
background for the valuable resources.<br />
A firmer tone, even more accu<strong>si</strong>ng, is that of Rosenberg, who joins Clark in the hypothe<strong>si</strong>s according to<br />
which “ as long as sustainable development is not a low-cost propo<strong>si</strong>tion, and also as long as the developed countries<br />
[…]are not willing to confront the staggering price tag, diplomatic resources and public and private monies will be<br />
directed toward maximizing the benefits to be derived from trade liberalization […]” (Rosenberg 1994). Rosenberg<br />
goes even further invoking, according to a phrase from the “The Economist”, “the green protectionism“: sustainable<br />
development use not as a purpose itself but as a pretext to impose terms which to serve some selfish economic goals.<br />
The problem that arises is therefore that of reconciling intra- and inter-generational interests. Erlet Carter<br />
noted that “the principles of sustainable development are widely accepted, but, given the conflicts of interests that<br />
occur over time and space, their resolution is likely to be problematic” (Carter 1995). Ted Trainer, for instance, is<br />
among those proclaiming a “healthier” economy, meaning one that is based on principles of sustainability and<br />
implicitly social justice, regarding by oppo<strong>si</strong>tion the prevailing capitalist method of production as self-destructive<br />
and inherently unjust (Trainer 1966). Trainer shows that, in fact, economic growth has harmed the world through<br />
unemployment, inequality on a large scale, social fragmentation and plundering of the environment. His critique<br />
however distincts itself from the wide current of opinions according to which, through institutional intervention, the<br />
current economic system can provide adequate protection to the environment. In exchange, the author invoques the<br />
need for radical change, rejecting the operations and principles which lye at the ba<strong>si</strong>s of both the capitalist economy<br />
and the socialist state model.<br />
There are therefore voices contesting the relevance of con<strong>si</strong>dering sustainable development; if we choose<br />
however to take it into discus<strong>si</strong>on (as we have in fact argumented above), we must face the issue of coordinating it to<br />
economic development. Again, there are other voices contesting the fundamentals of the capitalist economic model<br />
currently prevailing in western culture, voices which are strengthened by the distrust which the current cri<strong>si</strong>s has<br />
generated. If we again accept the general principles of this economic model, then it is worth analy<strong>si</strong>ng the interaction<br />
between the push for economic development and the preoccupation for sustainable development. Exemples and<br />
experiences have shown the pos<strong>si</strong>bility of a lack of coordination, or even an undermining of sustainable development<br />
from the part of that which, at least in theoretical built, wishes to be one of its components, namely economic<br />
development.<br />
In 1997, Debra Straussfogel compared the ranks of 66 countries according to GDP per capita with the<br />
respective ranks according to a compo<strong>si</strong>te index compri<strong>si</strong>ng four classes of elements: ecological (refering to the<br />
quality of the environment and the diver<strong>si</strong>ty of the habitat), human capital (<strong>si</strong>ze and structure of the population,<br />
education, health, and characteristics of the workforce), production capital (national income and its allocation, wealth<br />
and some elements of infrastructure), and finally institutional capital (Strausfogel, 1997). Finding itself among the<br />
countries con<strong>si</strong>dered for the analy<strong>si</strong>s, Romania, for instance, ranked 44th by GDP per capita in the year 1992, but<br />
31st by the compo<strong>si</strong>te index. The correlation index as calculated between the two rankings was of 0,87, indicating a<br />
strong link which leaves some room for sporadic exceptions. It comes as no surprise, for example, that it is precisely<br />
the production capital among the four elements in strongest correlation with the GDP per capita, as actually being a<br />
component of the latter. Once the strong interaction between economic and sustainable development mathematically<br />
fundamented, the debate shifts towards the direction in which the two influence one another. Coming back to<br />
Carter’s study undertaken for the restraint case of tourism, he describes a matrix in which each of the two aspects<br />
15
analyzed – the environmental one, respectively the aspect of human interests, may reach either of two outcomes as a<br />
result of a given activity – loss, respectively gain (win/loose). If by the examples illustrated, the loose/loose <strong>si</strong>tuation<br />
is generated by the motivation of misunderstood economic interest, the <strong>si</strong>tuation by which some human interest are<br />
satisfied to the detriment of the environment does not support itself beyond a short-term period. On a longer term, the<br />
environmental resource exploited will come to be exhausted or will loose its value, thus tran<strong>si</strong>tioning into a<br />
loose/loose <strong>si</strong>tuation. The exclu<strong>si</strong>ve pursuit of immediate interest, with disregard for perspective vi<strong>si</strong>on, therefore<br />
proves an unprofitable investment in the end.<br />
Conclu<strong>si</strong>ons<br />
The arguments in the first part of the paper were meant to defend the principles which stood as a base for<br />
the development of the sustainable development concept. Our purely personal opinion is that arguments such as<br />
insufficient understanding of the concept, the risc associated with a complex and large-scale initiative or lack of need<br />
for such an initiative are just as many pretexts for denying an clearly observable reality. By a suggestive metaphore,<br />
Boulding associated humans on Earth with travelors through space, who need to permanently recule their wastes in<br />
order to survive. What’s more, Hanson drew attention upon the nearly invariable tendency of organisms to extend<br />
their populations beyond the limits of the resourses of which they dipsose, at which time a self-consuming effect is<br />
triggered, and communities begin devouring life-sustaining resouces at a suicidal rate. What follows is a natural selfregulatory<br />
process, the dratatic demise of the population in question. Transpo<strong>si</strong>ng this model into human terms,<br />
industrial technologies for increa<strong>si</strong>ng the production of food per capita and the development of medicine allowed an<br />
explo<strong>si</strong>on o population beyond the natural self-regulating systems (such as the self-consuming effect anf the<br />
Malthu<strong>si</strong>an principle). Hanson did nonetheless foretell the reactivation of the self-consuming effect as a result of the<br />
explo<strong>si</strong>on of consumtion and waste.<br />

cu noosfera. Aşadar putem înfrunta viitorul cu încredere. Este în mâinile noastre. Nu îi vom da drumul”. Discursurile<br />
WCED şi UN propuneau o paradigmă în care eficienŃa şi tehnologia ar produce rezultate sporite cu resurse restrânse,<br />
conştiinŃa culturală şi ecologică ar conserva biodiver<strong>si</strong>tatea, potenŃialele populaŃiei şi ale eco<strong>si</strong>stemelor ar fi<br />
armonizate, producŃia agricolă ar beneficia de pe urma redefinirii folo<strong>si</strong>rii pământului şi al politicilor naŃionale de<br />
agricultură raŃionale, factorii de mediu ar fi integraŃi integral cu deciziile de dezvoltare economică la toate nivelurile,<br />
echitatea şi democraŃia ar triumfa. Un model la limita utopiei pe care oricine ar fi mândru să şi-l însuşească şi să-l<br />
apere, o cruciadă a dreptăŃii pentru oameni şi natură.<br />
Totuşi, cea mai vehementă critică la adresa uşurinŃei de implementare a dezvoltării durabile, în acord cu cel<br />
mai mare obstacol întâlnit până acum, este conflictul de interese pe termen scurt cu dezvoltarea economică a<br />
anumitor entităŃi. Dincolo la apelul la etică trebuie în acest sens cultivată conştiinŃa, dimpotrivă, a corelaŃiei pozitive<br />
dintre dezvoltare durabilă şi dezvoltare economică pe termen mediu sau lung. Dezvoltarea economică constituie unul<br />
dintre pilonii dezvoltării durabile, dar, prin subminarea celorlalŃi, dezvoltarea economică devine nesustenabilă atât<br />
din punct de vedere etic, cât şi din punct de vedere pragmatic, în sensul în care va sfârşi într-un efect autofag.<br />
Această conştiinŃă trebuie însuşită în primul rând de forurile de decizie şi reglementare de la cel mai înalt nivel,<br />
pentru ca apoi, prin măsuri şi reglementări adecvate, să condiŃioneze dezvoltarea economică a diferitelor entităŃi de o<br />
abordare sustenabilă. Voi concluziona aşadar prin afirmaŃia că dezvoltarea durabilă este o iniŃiativă necesară şi<br />
implementabilă, dar condiŃionată de reglementări şi decizii adoptate prin atenta con<strong>si</strong>derare a unui orizont de timp<br />
mediu şi lung, începând de la forurile cele mai înalte până la responsabilitatea individuală.<br />

Introduction<br />
Banks rely on credit and confidence in the debtor's ability to pay debts. Face to face with the<br />
pressure from the market and regulations, banks build their confidence on the ba<strong>si</strong>s of statistical<br />
tools to constrcut models ]n order to predict firms’ bankruptcy known as Rating and Scoring<br />
Models. Rating a company is defined as an estimate of the financial <strong>si</strong>tuation and the likelihood<br />
that a company becomes bankrupt in a certain period of time. "The overall objective of credit<br />
18
ating prediction is to biuld models that can extract knowledge of credit risk evaluation form past<br />
observation and to apply it to evaluate credit risk of companies(...)" (Huang et al., 2003, pg 544).<br />
Applying statistical models in corporate bankruptcy has become popular with the application of<br />
discriminant analy<strong>si</strong>s of Altman in 1968 and the introduction of Logit models with evidence from<br />
Martin and Ohlson in 1977 and 1980. The deci<strong>si</strong>on element in these models is the Score linear<br />
function, a hyperplane in multidimen<strong>si</strong>onal space that separates the bankrupt firms of the<br />
“surviving” ones. Company's score is a value function. Unlike the discriminant analy<strong>si</strong>s, Probit<br />
and Logit techniques conver the score directly into the probability of default by a mappingThe<br />
disadvantage is the "forced" linearity of the mapping that can distort results. The latest methods<br />
for clas<strong>si</strong>fying firms into "solvable" and "insolvable are neural networks and Support Vector<br />
Machines, known as SVM (non-parametric techniques for transforming scoring in probability of<br />
default). Many studies, including that of Kim (1993) compare the approach based on neural<br />
networks with linear regres<strong>si</strong>on analy<strong>si</strong>s and discriminant analy<strong>si</strong>s. We obtain that neural<br />
networks give better results than any other method in terms of clas<strong>si</strong>fication accuracy.<br />
In this paper we propose a brief foray into the clas<strong>si</strong>cal models based on analy<strong>si</strong>s of discriminant,<br />
then switch to the specific methods of clas<strong>si</strong>fication based on artificial intelligence techniques,<br />
which we will give a bigger space, <strong>si</strong>nce they gave higher accuracy rates than clas<strong>si</strong>cal statistical<br />
methods (discriminant analy<strong>si</strong>s, logit, probit). In bankruptcy prediction models, two major<br />
problems have raised: the accuracy of prediction and the explanatory power of models.<br />
Regarding the statistical methods it was concluded that <strong>si</strong>mple functions based on historical<br />
values and public, available data can be used as a first, very good approximation for the complex<br />
process of correct clas<strong>si</strong>fication in the two classes<br />
( solvent and insolvent companies). In brief, we will explain the neural networks algorthm and<br />
that of the SVM (topic that is not sufficient represented in Romanian literature compare to its<br />
many applications). We will present ways of selecting variables, financial ratios that characterize<br />
a company’s <strong>si</strong>tuation and that needs to provide a valuable set of information on its future<br />
development.<br />
The subject is of great <strong>si</strong>gnificance today, given the economic cri<strong>si</strong>s the world economy is<br />
facing. Policy banks in recent years of development was to create money through debt, creating a<br />
"speculative bubble" that eventually broke, leading to a sense of panic among the banks that have<br />
realized the importance of their customers’ creditworthiness. We thus explain the need to find the<br />
most preferment models that can provide banks a "clean" portfolio of customers. �¢���¤�¥<br />
1. Insolvency prediction models<br />
Interest in insolvency prediction has long been confined to academics, with most of the published<br />
material restricted to bu<strong>si</strong>ness and accounting journals specializing in esoteric and complicated<br />
subjects. A pos<strong>si</strong>ble reason why insolvency prediction models have not gained greater use in the<br />
bu<strong>si</strong>ness community is because it has been difficult to calculate the results<br />
In the last time, these models have gained even more ground, given the global economic cri<strong>si</strong>s<br />
and the importance for lending institutions to predict as correct as pos<strong>si</strong>ble the trustworthiness<br />
of their clients. We will present very briefly, as a result-form, three of the bankruptcy prediction<br />
models that were most common in the analy<strong>si</strong>s and constituted the starting point of most models.<br />
However, all developers of prediction models warn that the technique should be con<strong>si</strong>dered as<br />
19
just another tool of the analyst and that it is not intended to replace experienced and informed<br />
personal evaluation. Perhaps the best use of any of these models is as a "filter" to identify<br />
companies requiring further review or to establish a trend for a company over a number of years.<br />
If, for example, the trend for a company over a number of years is downward then that company<br />
has problems, that if caught in time, could be corrected to allow the company to survive.<br />
Altman model (USA,1968)<br />
Edward Altman is con<strong>si</strong>dered the dean of insolvency predictors. He was the first person to<br />
successfully use step-wise multiple discriminate analy<strong>si</strong>s to develop a prediction model with a<br />
high degree of accuracy. 22 financial ratios were tested in developing the Altman Model, that is<br />
the first result was a formula with 22 functions. The function that contributed the least to<br />
discriminating between the failed and successful companies was dropped and the statistical<br />
software was run again. This was repeated over and over each time dropping the ratio which least<br />
contributed to discriminating between the failed and successful companies. In the case of the<br />
Altman model, five functions remained. U<strong>si</strong>ng the sample of 66 companies, 33 failed and 33<br />
successful, Altman's model achieved an accuracy rate of 95.0%. Altman's model takes the<br />
following form:<br />
Z = 1.2A +1.4 B +3.3 C +0.6 D 0.999 E<br />
(1)<br />
If Z
81% more than one year prior to bankruptcy.<br />
Blasztck System(Canada, 1984)<br />
This is the only bu<strong>si</strong>ness failure prediction method outlined here that was not developed u<strong>si</strong>ng<br />
multiple discriminate analy<strong>si</strong>s. This system was developed by William Blasztk in 1984. The<br />
essence of the system is that the financial ratios for the company to be evaluated are calculated,<br />
weighted and then compared with ratios for average companies in that same industry. One of this<br />
method's strengths is that it does compare the company being evaluated with companies in the<br />
same industry<br />
2. Neural Networks<br />
Self-training machines is a separate branch of artificial intelligence. By automatic<br />
learning we analyze systems able to improve their performance with sets of training data.<br />
However, systems with artificial intelligence have limited pos<strong>si</strong>bilities for learning or even not at<br />
all. In general, the necessary knowledge is programmed within them, so that if the system<br />
contains an error it will not be able to correct it by itself, no matter how many times you run this<br />
program. Experience does not lead, unfortunately, to improved system performance, the<br />
algorithms are not automatically generated, new solutions can not be generated by analogy with<br />
the old ones or by discovering. Thus, systems with artificial intelligence are deductive systems,<br />
which can draw conclu<strong>si</strong>ons from knowledge within them or supplied, but can not themselves<br />
generate or acquire new knowledge. The following paragraphs summarize the key concepts in the<br />
field of artificial intelligence that will help us understand the logic of Neural Networks of<br />
Support Vector Machines.<br />
Learning and knowledge representation<br />
In learning a domain, a system contains many predefined concepts, structures,<br />
knowledge representation, heuristic rules and restrictions. We will review the two ba<strong>si</strong>c types of<br />
learning: supervised and unsupervised. In the case of supervised training, the network is<br />
submitted a set of training examples. Training example is a pair con<strong>si</strong>sting of an input-vector and<br />
the de<strong>si</strong>red/correct output. When we apply a network input vector, we calculate the network<br />
output and compare it with the output vector that we want to achieve. The difference between the<br />
latter and what we get is the error. Network weights are amended by an algorithm which tends to<br />
minimize this errors. The training vectors are applied sequentially, adjusting the corresponding<br />
weights until the total error associated with the whole training set reaches an acceptable value.<br />
This is how the network works through supervised learning. However, even if widespread, this<br />
type of training has been criticized as not logical form biological point of view, con<strong>si</strong>dering the<br />
idea that it is difficult to conceive the existence of a mechanism in brain that can compare the<br />
outputs de<strong>si</strong>red with the real onea, to then back-propagate throughout the networks’ neurons the<br />
corrections made. The issue that is raised is where do the de<strong>si</strong>red shapes come out from.<br />
However, it was discovered a self-organization form of the brain, from early stages of its<br />
development. This self-organization can not be explained by a supervised learning mechanism.<br />
Unsupervised Learning, on the other hand, provides a more plau<strong>si</strong>ble model for learning for<br />
biological systems.<br />
In a model of unsupervised learning the adjustment of weights is not based on<br />
21
comparing responses with predetermined ideal. The training set con<strong>si</strong>sts of input vectors. Without<br />
the correct answers being known (which supervised learning was called the "de<strong>si</strong>red output"), the<br />
comparison base to assess the errors, such models lead to the construction of entry groups, forms<br />
<strong>si</strong>milar property that we can call "self-organization”, which in clas<strong>si</strong>fication theory is equivalent<br />
to clustering. The logic of the network for this type of training is as follows: we applying two<br />
input vectors that are sufficiently <strong>si</strong>milar will generate the same form or output vector. Thus,<br />
when the network is presented a vector from a certain class, it will generate a specific output<br />
vector, with the difference from the type of instruction presented earlier that the answer a class of<br />
input vectors produces can not be determined before the end of training.<br />
In the specific type of network that we will apply in solving the problem of firms’<br />
insolvency prediction we use the supervised learning because we know in advance the two<br />
classes that the firms can be grouped in, ie the type of response which we expect. Of course, the<br />
problem can be treated also in terms of unsupervised learning. By selecting correct entryvariables<br />
variables , we obtain a separation, a self-organizing system of firms, in the two classes<br />
de<strong>si</strong>red.<br />
Neuronal calculus assumes, in addition to learning, another fundamental concept:<br />
knowledge representation, concept that involves the introduction of a method of recording what<br />
was learned. In conexionists patterns, as those reported in the paper, there is not a representation<br />
system separate from the learning one. Knowledge representation con<strong>si</strong>sts of a network, the<br />
connection weights and semantic interpretations attached to neurons. Applied in the context in<br />
which we will study the neural networks, we can identify a particular neuron with the bankruptcy<br />
for the firm. Activation 1 of the neuron shows firm bankruptcy , activation -1 shows the absence<br />
of bankruptcy and 0 the lack of information on the presence or absence of bankruptcy.<br />
General principles of neuronal calculus<br />
Neural modeling goal is to develop training systems that can operate in various fields, starting<br />
from a small amount of initial knowledge. These systems are exactly neural networks, systems<br />
with self-organization or, as we saw above, connexionsts systems. In fact, such a system con<strong>si</strong>sts<br />
of a network of interconnected elements, neuron like, performing <strong>si</strong>mple logic functions.<br />
Learning is achieved by changing the inten<strong>si</strong>ty of connection between elements, by changing the<br />
weights associated with these connections. Initial knowledge is synonymous with the initial<br />
configuration of the system, ie attributes, characteristics of objects. A separate section of the<br />
paper will be devoted to the choice of input variables, ie the attributes, features of objects which<br />
must provide the information about the type of object con<strong>si</strong>dered.<br />
2.1 Logic and a general pattern of neural networks<br />
A brief definition of a neural network is that of set of proces<strong>si</strong>ng elements (neurons, cognitive<br />
units or nodes of the network) highly interconnected. Con<strong>si</strong>dering a network with neurons,<br />
interconnected through a lot of weights or synaptic cognitions, each neuron with a number of<br />
inputs and a output, where inputs represent <strong>si</strong>gnals coming from other neurons or from the<br />
out<strong>si</strong>de world. Each neuron is characterized by three main elements: inputs - real<br />
numbers, the second element: synaptic weights associated with each input, so the number of all is<br />
also , marked with , also real numbers that weighted the input <strong>si</strong>gnal and the third<br />
element is the output, denoted by .<br />
�<br />
22
About the synaptic weights, if , then the synaptic weight is exciter, and if , we have<br />
an inhibitory weight. Given these elements, for each neuron we calculate its activation or product<br />
vector between input vector and the weight vector :<br />
In one of the clas<strong>si</strong>cal models of neural network, McCulloch-Pitts, each neuron is<br />
characterized by a threshold of excitement, t. Output neuron i, , takes a specific value,<br />
depending on the comparison with the total activation threshold t. For ease of writing , the<br />
threshold may be added, as input value 1 and t share, as a new term representing of the amount<br />
representing total activation. In other words, we complete the weighting vector with the value t<br />
and we add to the input vector a new component, 1. In fact, the output vector is a function value<br />
of the activation, including the threshold t:<br />
where .<br />
Shape function f depends on the model of neural networks studied. It is also called neuronal<br />
function, or output function of neuron activation, and oftenly non-linear neural functions are<br />
choose to work with. The most commonly used functions are: the threshold function associated<br />
with the McCulloch-Pitts model, the Signum function,thethres hold linear function, the <strong>si</strong>gmoid<br />
function.<br />
Of these, the linear threshold function and the <strong>si</strong>gmoidal function have a continuous codomenia<br />
interval (0.1), and not just the values 0 and 1. A <strong>si</strong>gmoidal function is defined in the following<br />
way:<br />
Training the network<br />
We con<strong>si</strong>der the neural network model presented above. Entries are represented as<br />
vectors, and many of these vectors represent the input vectors. The goal of a neural network is to<br />
transform a specific configuration entry in an output configuration. The output may correspond to<br />
an action realised by the network, such as a control problem. In this paper, we study the<br />
application of neural networks in problem of clas<strong>si</strong>fication. In general, the output can be any<br />
transformation of the input space, so the functioning of the network is the result of a projection, a<br />
transformation of the input vectors space into the output vector space, type of projection seen in<br />
the techniques of multidimen<strong>si</strong>onal data analy<strong>si</strong>s.<br />
By training the network we mean a method to built such an application or projection. In essence,<br />
training assumes that the network is provided enough examples of pairs of entry. With these<br />
examples, the network adapts its synaptic weights and thus it is forced to generalize an input<br />
application.<br />
23
In the clas<strong>si</strong>fication problem, the forms are submitted to the clas<strong>si</strong>fier that must clas<strong>si</strong>fy<br />
them in a preset lot of classes or categories. The learning process is part of the supervised<br />
techniques, ie the network is submitted various forms with their correct clas<strong>si</strong>fication. In our case,<br />
there are two categories of clas<strong>si</strong>fication: solvent and insolvent companies. So that the network<br />
works, we need a number of examples, usually it is con<strong>si</strong>dered an equal number of firms in each<br />
category. The weights between neurons and between the layers of neurons are then adjusted until<br />
the network is trained and it is able to correctly clas<strong>si</strong>fy objects (companies), different from those<br />
which were presented during training.<br />
2.2 Perceptron algorithm<br />
Even if with many limitations, the perceptron is a ba<strong>si</strong>c network which has aroused much interest<br />
because of its ability to learn to recognize <strong>si</strong>mple shapes. Being representative for a large range of<br />
training algorithms, we decided to show in more detail this algorithm, although it is the most<br />
<strong>si</strong>mple of a very large number of algorithms that have been developed over time, in order to<br />
correct the limits of the earlier ones. In other words, the perceptron model is the bottom from<br />
which arose all other neural networks. It should also be noted that these algorithms are suitable<br />
for problems of clas<strong>si</strong>fication and are u<strong>si</strong>ng supervised learning mechanism.<br />
The perceptron with a <strong>si</strong>ngle layer, although the <strong>si</strong>mplest neural network, is able to decide<br />
if a vector (a shape, an object) input belongs to one of the two training classes, denoted C1 and<br />
C2. We have a <strong>si</strong>ngle neuron with inputs . As explained above, the total neuron<br />
activation is calculated, taking into account the threshold value, t. The advantage of placing the<br />
threshold, t, as weight in defining neuron elements is very useful: the training algorithm can in<br />
this way shape also the threshold value together with the other weights. Assume that the<br />
perceptron output is given by the rule:<br />
where the vector is weight vector, separation vector or solution vector and the vector<br />
�has<br />
components.<br />
Equation is a hyperplane equation that separates the input vectors into two deci<strong>si</strong>on<br />
regions. Input vectors in the po<strong>si</strong>tive hyperplane correspond to class C1 (in our case this is the<br />
solvable firms class), and those located in the negative hyperplane correspond to class C2<br />
(insolvent firms). The separation hyperplane is an indetermination region, because we can not tell<br />
in which classes are the vectors belonging to it. ¡ � �<br />
For ease of adnotations, we make a <strong>si</strong>gn normalization of input vectors, with:<br />
So the hyperplane is a separation hyperplane for C1 and C2 if and only if we have the<br />
inequality: . If for two classes such a hyperplane exists, then the two classes<br />
are called linearly separable.<br />
Connection weights and the threshold, component of vector w, are adjusted through a <strong>si</strong>mple<br />
training algorithm, the perceptron algorithm. After applying this algorithm, we obtain a weight<br />
vector that separates the two classes. The procedure of training the perceptron is nothing but an<br />
24
iterative method to optimize a criterion function. The objective function chosen is the sum of<br />
distances form the points erroneously clas<strong>si</strong>fied to the hyperplane determined by the weight<br />
vector w.<br />
Next, we detail the calculation of the criterion or objective function. The set of training con<strong>si</strong>sts<br />
of pairs , where is the correct answer (expected) for the input of the<br />
network. Clas<strong>si</strong>fication error for a wrong clas<strong>si</strong>fied vector, , is the distance from this vector to<br />
hyperplane , , given the hyperplane equation. So, the criterion fnction will<br />
be the sum of errors that we want to minimize:<br />
where is the set of points incorrectly clas<strong>si</strong>fied by the weight vector w. ¡���<br />
To minimize this function we are u<strong>si</strong>ng a gradient type method. Criterion function value in step k<br />
of the gradient method will be:<br />
� where is the set of wrongly clas<strong>si</strong>fied points of vector . Let us now refer to the method<br />
of minimization of gradient. This is an iterative method of constructing a set of vectors<br />
,, where the vector is obtained from the vector of step as follows:<br />
In this formula is a po<strong>si</strong>tive number representing the <strong>si</strong>ze of movement towards of the<br />
weight vector in the direction given by , called direction of descent. In such methods, the<br />
direction of descent is con<strong>si</strong>dered the antigradient of the function to be minimized:<br />
¨ For convenience, at every step is more convenient to con<strong>si</strong>der all points of the training set and not<br />
just those wrongly clas<strong>si</strong>fied. However, the vector is amended only for those items<br />
incorrectly clas<strong>si</strong>fied by the weight vector . Taking , a po<strong>si</strong>tive constant (rate of<br />
training of the network), the rule of correction becomes:<br />
The algorithm itself is conducted as follows: at the first step we initializes the weights and the<br />
threshold value. We then choose the constant c, usually a po<strong>si</strong>tive value and less than one. The<br />
perceptron learning algorithm compares the output produced by the network with the class of the<br />
input vector. In case of an incorrect clas<strong>si</strong>fication, the weight vector is changed. If not, it remains<br />
unchanged. If at a certain number of consecutive steps there is not a change in the weight vector,<br />
then all the input vectors (in essence, examples given to the network) are correctly clas<strong>si</strong>fied by<br />
the weight vector of the last step of the algorithm. At this time, the network is trained and able to<br />
correctly clas<strong>si</strong>fy any unknown vector.<br />
25
The multi-layer perceptron<br />
Given the very <strong>si</strong>mple topology of the network, which provides space divi<strong>si</strong>on in just two<br />
semiplanes, there are many limitations of the <strong>si</strong>ngle layer perceptron. Even for <strong>si</strong>mple problems is<br />
preferable to use a network with a more complex architecture. A solution in this regard is the<br />
introduction of several layers of neurons between input neurons and output. Layers located<br />
between the first and last level of the network (between the layer containing the input and the<br />
layer containing the outputs) are called hidden layers. If a network can not solve a problem,<br />
sometimes it is sufficient to expand the number of neurons in the network or introduce one or<br />
more hidden layers. Perceptrons with multiple hidden layers can solve different problems: a<br />
perceptron with one layer and one output can only generate deci<strong>si</strong>on regions in the form of<br />
semiplane (as we saw above); a two-layer perceptron can form convex areas of deci<strong>si</strong>on (pos<strong>si</strong>bly<br />
infinite), obtained by the intersection of the semiplanes generated by each neuron in the first<br />
layer. Each neuron in the hidden layer acts as a standard perceptron and generates a separation<br />
hyperplane. A neuron in the second hidden layer generates a more complicated deci<strong>si</strong>on region<br />
by u<strong>si</strong>ng the semiplanes obtained by the neurons in the first layer.<br />
A clas<strong>si</strong>cal algorithm for training multilayer perceptronului was proposed in 1987 by Widrow.<br />
This algorithm uses the "principle of the lowest disturbance", which involves changing weights<br />
of neurons whose response is less vague. Starting from the input field to the output, we slightly<br />
modify the weights of nodes whose activation is nearest to zero, so that adjustment weights will<br />
cause a small reduction in error output. Changes stop when the minimum error is achieved or an<br />
acceptable value of the error. Often the weights are adjusted u<strong>si</strong>ng a training scheme based on the<br />
method of back propagation. This kind of procedures back propagated through the entire<br />
network an error representing the difference between de<strong>si</strong>red outputs and observed ones.<br />
3. SVM<br />
Many new techniques / computational methods and machine-learning generalize the idea of<br />
estimating statistical parameters. The method was introduced by Vapnik and is a non-linear<br />
statistical technique that in many applications (optical character recognition, medical diagno<strong>si</strong>s)<br />
proved to have a high accuracy. The technique is based on a flexible clas<strong>si</strong>fying function<br />
controlled only by adjusting some parameters. The solution offered is stable, <strong>si</strong>nce it changes<br />
only slightly to changes in the data, for the methodology is based on the convex optimization<br />
problem. Support vectors represent a way of building a clas<strong>si</strong>fication N-dimen<strong>si</strong>onal hyperplane,<br />
which optimally separates the items into two classes. Thus, the separation of solvent firms and<br />
insolvent ones is done so that the distance between the two classes is maximised, while incorrect<br />
clas<strong>si</strong>fications are penalized proportional to the distance to the class to which they really belong<br />
to. Models based on support vectors are very <strong>si</strong>milar to neural networks. In fact, SVM u<strong>si</strong>ng<br />
kernel <strong>si</strong>gmoidal functions are equivalent to a perceptron neural network with two layers. In<br />
literature specific to SVM models a predictor variable is called an attribute, and a transformed<br />
attribute used to define the hyperplane is called a feature. The process of choo<strong>si</strong>ng the most<br />
suggestive representation is called the selection of characteristics. A set of characteristics that<br />
describe an object is called vector. Thus, the purpose of modeling with support vectors is to find<br />
an optimal hyperplane to separate clusters of objects so that objects of a class to be <strong>si</strong>tuated on<br />
one <strong>si</strong>de of the hyperplane and the objects in the other class on the other <strong>si</strong>de of the hyperplane.<br />
26
Vectors near the hyperplane, who actually provide the separation condition are the support<br />
vectors. Advantage over other techniques lies in clas<strong>si</strong>fication by modeling non-linear separating<br />
surfaces. For a better understanding of the method, let’s look at Figure 1.<br />
Margi<br />

Support<br />
Vectors<br />
Assume we wish to perform a clas<strong>si</strong>fication, and our data has a categorical target variable with two categories. Also<br />
assume that there are two predictor variables with continuous values. If we plot the data points u<strong>si</strong>ng the value of one<br />
predictor on the X axis and the other on the Y axis we might end up with an image such as shown above. One<br />
category of the target variable is represented by rectangles while the other category is represented by ovals. In this<br />
idealized example, the cases with one category are in the lower left corner and the cases with the other category are<br />
in the upper right corner; the cases are completely separated. The SVM analy<strong>si</strong>s attempts to find a 1-dimen<strong>si</strong>onal<br />
hyperplane (i.e. a line) that separates the cases based on their target categories. The question is which line is better,<br />
and how do we define the optimal line. The dashed lines drawn parallel to the separating line mark the distance<br />
between the dividing line and the closest vectors to the line. The distance between the dashed lines is called the �©¢�£�. The vectors (points) that constrain the width of the margin are the �§���¢��¤���¢�. Figure 1 illustrates this. If<br />
all analyses con<strong>si</strong>sted of two-category target variables with two predictor variables, and the cluster of points could be<br />
divided by a straight line, life would be easy. Unfortunately, this is not generally the case, so SVM must deal with<br />
more than two predictor variables, separating the points with non-linear curves, handling the cases where clusters<br />
cannot be completely separated, and handling clas<strong>si</strong>fications with more than two categories. The <strong>si</strong>mplest way to<br />
divide two groups is with a straight line, flat plane or an N-dimen<strong>si</strong>onal hyperplane. But what if the points are<br />
separated by a nonlinear region such as shown below (Figure 2)? In this case we need a nonlinear dividing line.<br />
to<br />
���¢¤¡��¦¤�¤�©¢©¥�¡�¡�¡��¤¨¥���¥¡¥�¡¨�©��¤���¥¦����¡¢¥£¤¨¥¡¢�<br />
Rather than fitting nonlinear curves to the data, SVM handles this by u<strong>si</strong>ng a £¤¢�¤¨�§���£��<br />
map the data into a<br />
different space where a hyperplane can be used to do the separation. The kernel function may transform the data into<br />
a higher dimen<strong>si</strong>onal space to make it pos<strong>si</strong>ble to perform the separation. Figure 2 illustrates this very well.<br />

The conclu<strong>si</strong>on that we draw on the accuracy of the model is based on widely accepted criteria:<br />
the accuracy rate (used as a criterion for model selection), but also alpha and beta errors.<br />
Accuracy rate shows what percent of companies were correctly clas<strong>si</strong>fied correctly by the<br />
proposed model. The alpha error is the percentage of insolvent companies between the solvent<br />
ones and the Beta error is the percentage of solvent companies between insolvent ones. A method<br />
of clas<strong>si</strong>fication has a greater power , if for a given alpha error , results a smaller beta error.<br />
Since it is practically impos<strong>si</strong>ble to try all combinations of variables to choose one that yields<br />
overall the best AR, we need to apply a selection procedure. We may apply a backward variable<br />
selection procedure (BSP) or a forward selection procedure (FSP) . The BSP starts with the full<br />
model which includes all variables. At the first step one of the variables is consecutively<br />
excluded and the AR of each reduced model is computed. The model that has the highest AR will<br />
be examined at the second step when one more variable is consecutively excluded and ARs are<br />
compared. The procedure continues until a univariate model is selected by reducing a bivariate<br />
model. The FSP starts with the selection of a univariate model and continues until all variables<br />
are included. At each step the variable is kept whose addition to the model produced the highest<br />
AR. In the clas<strong>si</strong>fication that we propose, the input variables refer to financial ratios,<br />
profitability, liquidity, investments, leverage, growth, etc.<br />
4.1 Suggestions for adapting the models to the new economic <strong>si</strong>tuation<br />
In this paragraph we introduce some ideas for adapting the models that we presented to the new<br />
economic context. The biggest problem raised in applying the current models is that they are<br />
based on historical data in order to forecast whether a firm will or will not become bankrupt in a<br />
specific time horizon. Relevance of historical data at this point may be zero, especially in the case<br />
of construction companies where the spectacular growth of the industry, was followed by an<br />
unexpected decline. Therefore, we can not draw relevant conclu<strong>si</strong>ons having in mind the financial<br />
Φ<br />
C2<br />

statements of a year or two ago. We propose in this case an amendament of profitability ratios<br />
with a certain percentage, depending on the industry in which the firm operates and in line with<br />
results obtained by triggering the economic cri<strong>si</strong>s. This will solve two problems: the nonrelevance<br />
of historical data and incoroporating in the model the trend analy<strong>si</strong>s of the industry.<br />
But not only profitability has to suffer.<br />
Companies with low capital input and the low shareholder contribution may be between the most<br />
affected. Selling an asset that is not used in operational activity may be an elegant solution to<br />
overcome problems of liquidity on the short term. However, when the asset base is very low, big<br />
problems occur. Particular attention should be paid to these ratios: Equity / Total Assets and<br />
Equity + Shareholders Contribution / Total Assets). Always bear in mind the working capital, by<br />
reporting it to the turnover, the total sales. If working capital is negative, there is a <strong>si</strong>gn of an<br />
unbalanced company, an alarm <strong>si</strong>gnal is immediately fired because this can lead very quickly to<br />
the company’s insolvency. Debts to banks or to suppliers that exceed a certain number of days<br />
are elements that can trigger firm bankruptcy, given the existing legal framework. We believe<br />
that one should include an indicator that reflects the hang debts over 60 days (over the entities<br />
listed above) in total debts.<br />
Conclu<strong>si</strong>ons<br />
In the present paper we tried to present the newest and most advanced techniques for prediction<br />
of insolvency of a company. As support Hardle, Moro and Schäfer (2007, pg 11), SVM technique<br />
has the greatest power to identify the solvent companies, which means that banks will grant loans<br />
with less risk due to better separation of solvent companies and insolvent ones. We have<br />
presented in detail neural network technology as it constitutes the starting point for SVM. A<br />
neural network works by the following principle: there are several layers of nodes (input node<br />
layer, output nodes layer and hidden nodes layer). The network is Enabled from the input layer<br />
through the hidden layer to the output layer. Initially, the network has a set of random weights,<br />
then they are adjusted each time a pair of input-output is processed. Each pair is processed in two<br />
stages: step "forward" and a step backward. The weights are updated to stabilize the network<br />
when the network is con<strong>si</strong>dered to be trained and any input vector will be correctly clas<strong>si</strong>fied.<br />
Techniques based on Artificial Intelligence are those that gave the best results.<br />
However, giving the current economic context, some changed are to be made over this models.<br />
They relate to the input variables (input vectors) that are selected and not to the logic of<br />
clas<strong>si</strong>fication itself, which remains the same. Suggestions of choo<strong>si</strong>ng input variables to better<br />
reflect the impact of the cri<strong>si</strong>s on companies are provided in the last section of the paper.<br />
The subject is of major importance in the economy, credit must be made with caution in any<br />
period, whether of boom or reces<strong>si</strong>on. Caution should not mean stopping loan. Economic growth<br />
means investments which are largely supported by credit. Here's a feedback loop that gives us a<br />
perspective on the importance crediting and knowing the creditworthiness of the client and the<br />
adequate forecasts on their activities.<br />

Introduction<br />
Humans have been manually extracting information from data for centuries, but the increa<strong>si</strong>ng volume of<br />
data in modern times has called for more automatic approaches. As data sets and the information extracted from<br />
them has grown in <strong>si</strong>ze and complexity, direct hands-on data analy<strong>si</strong>s has increa<strong>si</strong>ngly been supplemented and<br />
augmented with indirect, automatic data proces<strong>si</strong>ng u<strong>si</strong>ng more complex and sophisticated tools, methods and<br />
models. The proliferation, ubiquity and increa<strong>si</strong>ng power of computer technology has aided data collection,<br />
proces<strong>si</strong>ng, management and storage. However, the captured data needs to be converted into information and<br />
knowledge to become useful. Data mining is the process of u<strong>si</strong>ng computing power to apply methodologies,<br />
including new techniques for knowledge discovery, to data.<br />
Data mining aims to discover so far unknown knowledge in large datasets. The most important step thereby<br />
is the tran<strong>si</strong>tion from subsymbolic to symbolic knowledge. Data mining can be defined as the inspection of a large<br />
dataset with the aim of knowledge discovery. Knowledge discovery is the discovery a new knowledge. Central issue<br />
of data mining is the tran<strong>si</strong>tion from data to knowledge. Symbolically represented knowledge, such data mining is<br />
the representation of facts in a formal language such that an interpreter with competence to process symbol can<br />
utilize this knowledge. Then human beings can be able to read, understand and evaluate this knowledge.<br />
31
Data mining can be done in the following<br />
steps (see figure 1):<br />
- inspection of the dataset<br />
- construction of clas<strong>si</strong>fiers<br />
- knowledge conver<strong>si</strong>on and<br />
- validation<br />
Most previous studies have concentrated on<br />
showing binary-valued transaction data. However,<br />
transaction data in real-world applications usually<br />
con<strong>si</strong>st of quantitative values, so de<strong>si</strong>gning a datamining<br />
algorithm able to deal with quantitative data<br />
presents a challenge to workers in this research field.<br />
The k-means algorithm<br />
The k-means algorithm is a <strong>si</strong>mple iterative method to partition a given dataset into a user specified the<br />
number of clusters, £. In statistics and machine learning, k-means clustering is a method of cluster analy<strong>si</strong>s which<br />
aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest<br />
mean.<br />
The k-means algorithm is an algorithm to as<strong>si</strong>gn K centers to represent the clustering of N points (K
with different starting conditions. It has been shown that there exist certain point sets on which k-means takes super-<br />
2<br />
Ω(<br />
)<br />
polynomial time: to converge, but these point sets do not seem to arise in practice.<br />
The k-means clustering algorithm is commonly used in computer vi<strong>si</strong>on as a form of image segmentation.<br />
The results of the segmentation are used to aid border detection and object recognition. In this context, the standard<br />
Euclidean distance is usually insufficient in forming the clusters. Instead, a weighted distance measure utilizing pixel<br />
coordinates, RGB pixel color and/or inten<strong>si</strong>ty, and image texture is commonly used.<br />
There are a lot of variations of k-mean algorithm:<br />
- The expectation-maximization algorithm (EM algorithm) maintains probabilistic as<strong>si</strong>gnments to clusters,<br />
instead of deterministic as<strong>si</strong>gnments.<br />
- k - means++ seeks to choose better starting clusters.<br />
- The filtering algorithm uses kd-trees to speed up each k-means step.<br />
- Some methods attempt to speed up each k-means step u<strong>si</strong>ng corsets or the triangle inequality.<br />
- Escape local optima by swapping points between clusters.<br />
Process of taking deci<strong>si</strong>ons in bu<strong>si</strong>nesses and the economic cri<strong>si</strong>s<br />
Bu<strong>si</strong>ness knowledge, the extraction of rules and their use in the deci<strong>si</strong>on process allow us to move from the<br />
analytical phase to the production of a deci<strong>si</strong>on engine. Once the model has been chosen and tested with a data set,<br />
the clas<strong>si</strong>fication rule can be generalized. For example, we will be able to distinguish which customers will be more<br />
profitable or to calibrate differentiated commercial policies for different target consumer groups, thereby increa<strong>si</strong>ng<br />
the profits of the company.<br />
Having seen the benefits we can get from data mining, it is crucial to implement the process correctly in<br />
order to exploit it to its full potential. The inclu<strong>si</strong>on of the data mining process in the company organisation must be<br />
done gradually, setting out realistic aims and looking at the results along the way. The final aim is for data mining to<br />
be fully integrated with the other activities that are used to support company deci<strong>si</strong>ons. This process of integration<br />
can be divided into four phases:<br />
• Strategic phase. In this first phase we study the bu<strong>si</strong>ness procedures in order to identify where data mining<br />
could be more beneficial. The results at the end of this phase are the definition of the bu<strong>si</strong>ness objectives for a pilot<br />
data mining project and the definition of criteria to evaluate the project itself.<br />
• Training phase. This phase allows us to evaluate the data mining activity more carefully. A pilot project is<br />
set up and the results are assessed u<strong>si</strong>ng the objectives and the criteria established in the previous phase. A<br />
fundamental aspect of the implementation of a data mining procedure is the choice of the pilot project. It must be<br />
easy to use but also important enough to create interest.<br />
• Creation phase. If the po<strong>si</strong>tive evaluation of the pilot project results in implementing a complete data<br />
mining system it will then be necessary to establish a detailed plan to reorganise the bu<strong>si</strong>ness procedure in order to<br />
include the data mining activity. More specifically, it will be necessary to reorganise the bu<strong>si</strong>ness database with the<br />
pos<strong>si</strong>ble creation of a data warehouse; to develop the previous data mining prototype until we have an initial<br />
operational ver<strong>si</strong>on and to allocate personnel and time to follow the project.<br />
• Migration phase. At this stage all we need to do is to prepare the organization appropriately so that the data<br />
mining process can be successfully integrated. This means teaching likely users the potential of the new system and<br />
increa<strong>si</strong>ng their trust in the benefits that the system will bring to the company. This means constantly evaluating (and<br />
communicating) the results obtained from the data mining process.<br />
If we want to give a diagno<strong>si</strong>s of a company we have to calculate a lot of rates between the two po<strong>si</strong>tions of<br />
the balance sheet and/or the result account. Theoretical, and practical too, we can compute a lot of rates. For<br />
example:<br />
a. rates of financial structure;<br />
b. rates of liquidity and treasury - are rates of financial structure too but they express the potential of<br />
company for paying depts. on the short term;<br />
c. profitability rates which are computed by u<strong>si</strong>ng elements from the result account.<br />
In the paper I made a clas<strong>si</strong>fication of 15 companies, depending of the next economic-financial rates,<br />
computing from balance sheets:<br />
I1: depts./social capital I5:depts./assets<br />
I2: income/assets I6: the growth assets rate<br />
I3: gross profit/assets I7: net profit/income<br />
I4: social capital/income<br />
The algorithm used to analyze and diagnostic firms or company through financial indicators is based on:<br />
33
� Grouping those firms in unitary classes based on seven indicators. For this thing we will use an hierarchical<br />
aggregate algorithm.<br />
a. Eigenvalues that offers informations about fitting quality are represented by specific falues of<br />
correlation matrix.<br />
b. Factor Score Coefficients offers informations about principal axis.<br />
� Grouping of those seven financial indicators in homogeneous classes. The start point is the primary data<br />
matrix, and then we calculate Euclidian distances between matrix columns.<br />
� Based on scores matrix from SPSS output we find two indicators with high scores. With this two indicators<br />
we can catalogue the studied firms based on scoring values we obtain.<br />
Figure 2 The dendogram of sample of 15 companies from electrical sector<br />
From the SPSS output dendogram results that we can form many classes depending on its ‘cut’. If the<br />
‘cut’ is between 15 and 20 we can form 3 classes: (12,15,14); (9,10,3,1,7) and (2,8,4,5,11,13,6). The most convenient<br />
<strong>si</strong>tuation is when the ‘cut’ is <strong>si</strong>tuated between 20 and 25, when we can form 2 classes: (14,15,12,9,10,3,1,7) and<br />
(2,8,4,5,11,13) because this is the purpose of the analy<strong>si</strong>s.<br />
For analy<strong>si</strong>s we take two indicators: I3 (gross income/total asset) and I4 (registered capital/ turnover). If<br />
a company has a good value for I3 and a bad value for I4 then this firm is has a good profitability, otherwise this firm<br />
is not going to well form financial point of view.<br />
The I4 indicator being aggregated by divi<strong>si</strong>on of gross income at total assets, shows if a firm has profit.<br />
If this ratio is grater this means that the company is doing very well. The I3 indicator aggregated by divi<strong>si</strong>on of<br />
registered capital at turnover, shows if a firm has loses or not. If this ratio is smaller the status of the company is<br />
good and if this ratio is grater the firm will enter in bankrupt.<br />
Conclu<strong>si</strong>on<br />
Bu<strong>si</strong>nesses employing data mining quickly see a return on investment, but also they recognize that the<br />
number of predictive models can quickly become very large. Rather than one model to predict which customers will<br />
churn, a bu<strong>si</strong>ness could build a separate model for each region and customer type. Then instead of sending an offer to<br />
all people that are likely to churn, it may only want to send offers to customers that will likely take to offer. And<br />
finally, it may also want to determine which customers are going to be profitable over a window of time and only<br />
send the offers to those that are likely to be profitable. In order to maintain this quantity of models, they need to<br />
manage model ver<strong>si</strong>ons and move to automated data mining.<br />
Data mining is the process of sorting through large amounts of data and picking out relevant information. It<br />
is usually used by bu<strong>si</strong>ness intelligence organizations, and financial analysts, but is increa<strong>si</strong>ngly being used in the<br />
sciences to extract information from the enormous data sets generated by modern experimental and observational<br />

Introduction<br />
Starting with the eighteen century, we passed periodically some economic declines. Once appeared these<br />
moments, were named panic and when those were frequently had appeared other names: depres<strong>si</strong>on, economicfinancial<br />
crises or reces<strong>si</strong>on.<br />
The Great Depres<strong>si</strong>on started in 1929 and end at different times from 1930s to 1940s and it was the most<br />
important economic depres<strong>si</strong>on on the last century, now u<strong>si</strong>ng it as an example of how the world's economy may fall.<br />
The USA economy decline was the main factor that pushed the downturns to other countries, and adding to<br />
the internal weaknesses of each country made conditions worse.<br />
The biggest economic cri<strong>si</strong>s from 1929 had negative consequences also for Europe, South<br />
America, Australia, Africa, or A<strong>si</strong>a.<br />
36
This period of decline had influenced also the politically aspects all over the world, by<br />
abandoning of clas<strong>si</strong>c economic liberal approaches and leading the way to neo-liberalism, or<br />
extremism.<br />
Even if there is <strong>si</strong>militude that makes it to be compared with that one, we must say that<br />
the present economical conditions in such process of globalization make it not having the<br />
consequences of that time.<br />
One reason is given by the richness of global economy, which allows all countries not to get the<br />
figures of that time: regarding the unemployment, industrial activity, and all sectors.<br />
So, depres<strong>si</strong>on is a necessary phase by which the market economy may bloom and liquidates the economic<br />
mistake, and reestablishes some proportions between consumption and investment.<br />
In this context the accounting process doesn’t make any exception. I will start from the<br />
premise that the cash <strong>si</strong>tuation must be presented more complex as a solution to express the<br />
continuity of a company’s activity.<br />
So we are propo<strong>si</strong>ng that for this statement to base the accounting records. ��¢ £�£§�¢��¢¢�£§�¡¤©�¦�£§�¢©¥¥���©�§�£ ��¦¥¥���¦�¦¢§���£��©¤��¢�£¥���©���£�¢�¢§��©�¥¢¤¢¥¦��£���©§��¦§�©¤�£�¦©§�¤©�<br />
For this issue we suggest an increa<strong>si</strong>ng of the Accounting Plan by adding some new<br />
analytics and synthetics. Also, it will be presented this statement for two big companies from<br />
Romania that are developing their activity in different markets, analyzing this aspect in decline<br />
period.<br />
How can be treasury accounting – a key – in a cri<strong>si</strong>s period?<br />
Regarding this economic evolution, the accounting aspect doesn’t make any exception of<br />
according more attention to the financial record. The main request in such conditions is having a<br />
strong cash <strong>si</strong>tuation. So, by practicing cash accounting in the meantime with an accrual one is a<br />
backup for depres<strong>si</strong>on periods.<br />
In such conditions, there is a determinate period of “waiting” when people are waiting for<br />
see which is the company’s behavior, firms are waiting to see which the governmental solutions<br />
are and the institutional is trying to be in accordance with the international rules as a result of the<br />
globalization process.<br />
Now, we are living another moment of economic decline from October 2008. In the last<br />
few months it is demonstrated that in such moment u<strong>si</strong>ng just the accrual is not a solution<br />
because cash is that express the financial power of a firm.<br />
Like on the 29’s, now, the main reasons of getting depres<strong>si</strong>on were represented by the<br />
capital market stock exchange and real estate that touched mountainous figures, driving to an<br />
inexistent richness of the companies and global economy.<br />
Also, regarding this presentation we mustn’t ignore the accounting aspects.<br />
It is already known that the engagement accounting express only the present incomes and<br />
expenses which are engaged for the moment and not the cash in-outflow, which are paid or<br />
collected.<br />
Because de cash <strong>si</strong>tuation is an important issue for a company, I try to purpose another<br />
way of recording the treasury operations.<br />
37
This represents to construct some temporal accounts – like those of incomings and<br />
expenses which could be closed through the permanent treasury account. This solution is almost<br />
the same with the Profit and loss account reasoning.<br />
So the increa<strong>si</strong>ng and decrea<strong>si</strong>ng of the economic advantages will not appear directly in<br />
the balance sheet account. It will be collected and paid u<strong>si</strong>ng the seasonal accounts (groups<br />
5.1.xxx and 5.2.xxx). So, these accounts must be clas<strong>si</strong>fied depending on the nature of activity<br />
(operating, investing and financing). Even if is complicate as profit and loss account (with<br />
incoming and expenses accounts – 6 th and 7 th classes), this general cash account must be closed<br />
by transferring all analytical accounts.<br />
Generally talking it is used a systematic recording because we are interested on the cash<br />
flow nature (paying the providers or dividends etc), and also the nature of element that is<br />
involved (cash in hand, or banking accounts, etc.).<br />
So, all cash in/out - flows should be first of all collected in or paid from those temporal<br />
accounts that will be after that closed by general cash account which going to express a final<br />
value of treasury but also all information regarding the activities that generated it.<br />
So, the 5 th classes that express cash and banking accounts may be divided into 2<br />
synthetics groups: 5.1.xxx - Cash inflows and 5.2.xxx - Cash outflows and those must be split<br />
into 3 activities each of one in following analytics:<br />
5.1.1. / 5.2.1. Operating activities<br />
5.1.2. / 5.2.2. Investing activities and<br />
5.1.3. / 5.2.3. Financing activities<br />
So the accounts of inflows will function as an assets account and will start by debiting it,<br />
and the accounts of outflows will function as a liabilities (pas<strong>si</strong>ve) account and will start by<br />
crediting it.<br />
Those two synthetics groups will be divided in analytical accounts according to the<br />
activity.<br />
We must mention that these accounts will behavior like the income and expense ones,<br />
that’s will be closed through a general account of cash given by 5.0.x – Cash and banking<br />
accounts – from the assets accounts - on the last day of a determinate period.<br />
Also each of these accounts may be split into treasury in hand – cash inflows and<br />
outflows or banking accounts and other way of expres<strong>si</strong>ng cash (in paper form)<br />
For example:<br />
401.1 = 5.2.1.1 (paying the provider/manufacturer) (1)<br />
5.1.1.1 = 411.1 (cash in from a customer) (2)<br />
So, in the end of the period (month), the final value will be:<br />
5.2.1.1 = 501 (3) and 501 = 5.1.1.1 (4)<br />
For a good understanding let’s take a look over the next figure which expresses the<br />
structure of General Cash Account:<br />
Figure 1 – General Cash Account Form<br />

So, the General Cash Account will be just like the Profit and loss account.<br />
The main aspect of this intention is that it makes the cash flow statements to be based on<br />
the accounting records not only on the information from the Balance sheet and Profit and Loss<br />
Account.<br />
The limit of the Cash flow statement (now) is also given by the <strong>si</strong>mplistic form of<br />
exposure, being present just some values without any additional information (that may be use it<br />
by implementing this kind of recording).<br />
According more attention to the cash <strong>si</strong>tuation doesn’t mean to ignore the accruals<br />
because it allows us to know which are the future collects and payments from the past and present<br />
revenues and expenses.<br />
In these circumstances (a strong cash <strong>si</strong>tuation) it doesn’t mean that a depres<strong>si</strong>on will not<br />
appear but its consequences may be decreased.<br />
Now, we may appreciate that the Cash flow Statement it is ba<strong>si</strong>ng on the information<br />
resulted from the Balance Sheet and Profit and Loss Account without any own recording. So, the<br />
treasury level may be determinate (for the moment) in a re<strong>si</strong>dual manner by starting from those<br />
two statements.<br />
Also it is remarkable that this <strong>si</strong>tuation has more an economic – financial vi<strong>si</strong>on and not<br />
an accounting one.<br />
That’s why a recommendation is that all operations that use cash to be recorded also in<br />
accounting process, even if this will involve an increa<strong>si</strong>ng number of accounts with some<br />
39
synthetics and analytical for these three kinds of activities especially in the companies which<br />
have an important and continually cash transfer or have a variable treasury for small periods.<br />
So, the only limit or disadvantage is represented by this increa<strong>si</strong>ng of accounting plan and<br />
also of the accounting process in a company by u<strong>si</strong>ng other some accounts. But this is the only<br />
way of evaluating correctly the cash <strong>si</strong>tuation first of all in a cri<strong>si</strong>s period (and not only), when<br />
the true richness is expressed by the treasury <strong>si</strong>tuation.<br />
Cash Flow – from the theory and practice<br />
For a good understanding we are going to analyze the Cash Flow Statement of 2 big<br />
companies from Romania which are developing their activity in different areas. We are talking<br />
about: SC Automobile Craiova SA and SC Rompetrol Well Services SA.<br />
The study will be presented for the period 2007 – 2008 following to expose which is the<br />
impact of the cri<strong>si</strong>s for every market in which those companies are active: automobile market and<br />
earth oil market.<br />
SC Automobile Craiova SA is the biggest Romanian auto producer and starting from<br />
September 1999 it is part of the French Renault Group. Its main activity is to produce and<br />
commerce automobile, spare parts, machines and other installations for auto industry.<br />
If we study the financial statements from 2007 – 2008 and analyze only Balance Sheet or<br />
Profit and Loss Account is not sufficient to form a correct image for cash <strong>si</strong>tuation. So, we are<br />
going to study the Cash Flow Statement – the net cash flow for each type of activity, by<br />
evidencing the treasury <strong>si</strong>tuation utility in the reces<strong>si</strong>on time (2008 – year of starting the decline<br />
period).<br />
Let’s take a look over the net cash flow repartition:<br />

activities<br />
In 2007 we see that, ba<strong>si</strong>ng on its main activity the company made investments in new<br />
products to assure a strong competitive on a market that is more and more scramble. Also, the<br />
financing activity has increa<strong>si</strong>ng. We must remark that 2007 is the year of bloom for the auto<br />
market, so the net treasury recording a value of 412.595.769,00 RON from 10.992.155,00 RON.<br />
Regarding the next year’s values we must mention the national and international context<br />
has record a decline period of reces<strong>si</strong>on in all kind of activities. So this market doesn’t make any<br />
exception, after a period of investing in this goods, the population has renounce for moment of it.<br />
We are able to see that all activities had decreased figures. Even thought the operating<br />
activity is enough to cover the investments and financing activity but not like in 2007. This<br />
evolution is ba<strong>si</strong>ng on the cash inflow from the start of 2008, when the cri<strong>si</strong>s effect doesn’t<br />
feeling, recoding in the end of the year 540.948.123,00 RON.<br />
So, we may see that the presented company is part of a sector with an increased potential but vulnerable of<br />
any changes of the market when the economic conditions generate a decline background.<br />
Regarding the second company Rompetrol Well Services (RWS) is a member company of Rompetrol NV<br />
Group <strong>si</strong>nce 2000, specialized in well services for the extraction of crude oil and natural gas. RWS offers specialized<br />
services in oil and natural gas fields at the national and international level.<br />

Also, in this case we may see the influence of the cri<strong>si</strong>s period, represented by a<br />
decrea<strong>si</strong>ng of net cash flow. This is the result of the main activity (operating) especially because<br />
being on a market which depends of other firms that are u<strong>si</strong>ng their products and services. So, the<br />
operating cash flow decreases from 16,970,754.00 RON to 6,425,635.00 RON, adding to that<br />
evolution a strong investments process from -9.400.501,00 RON to -12.942.600,00 RON.<br />
We are able to see that between theory and practice there are some limits regarding the<br />
interpretation of the results for both cases up presented from the cash statements point of view.<br />
There are 2 lists of increa<strong>si</strong>ng and decrea<strong>si</strong>ng of some elements of balance sheet and profit and<br />
loss account, but we can’t evaluate all operations that generate liquidities transfer.<br />
The correctly evaluation of in-out cash flow may be a base for determinate the economic<br />
and financial stability in cri<strong>si</strong>s conditions, especially for those companies that involve a high<br />
level of cash transfer.<br />
Conclu<strong>si</strong>on<br />
Coming back to the proposal of a new method of preparing Cash Flow Statement, this is<br />
influenced by those two statements presented which are not very detailed being just a <strong>si</strong>mple list<br />
of increa<strong>si</strong>ng or decrea<strong>si</strong>ng of some elements from balance sheet. This limited aspect of the<br />
2007<br />
2008<br />
42
statement is also sustained by the IAS 7 – Cash Flow Statement and other legal procedures that<br />
present just a list o few examples of operations for those three activities.<br />
So, by studying the Cash Flow Statement for these companies we can’t make a correct<br />
evaluation of all influences that generated operations with cash. We may appreciate that we must<br />
use also other financial statements (balance sheet, profit and loss account informative date or<br />
some explicative notes).<br />
For instance, we recommend for preparing this statement by practicing accounting records<br />
for an objective evaluation of correctness and utility of all cash actions. Also, in our presented<br />
<strong>si</strong>tuations we may observe exactly which are the implications for each activity that used cash and<br />
or which was its finality and not the evolution for the total account.<br />
Also, this article research was not propo<strong>si</strong>ng to change a financial statement – Cash Flow<br />
Statement – but to offer a solution for improving the information that is offered, ba<strong>si</strong>ng on<br />
accounting records especially in time of reces<strong>si</strong>on, so to evaluate correctly the financial<br />
stabilization of a company.<br />

Introduction<br />
At European level, in 2009, one can identify three aspects of the world financial cri<strong>si</strong>s: a credit cri<strong>si</strong>s, an<br />
economic system cri<strong>si</strong>s and a psychological cri<strong>si</strong>s related to consumption. In this material we will only deal with the<br />
economic aspect, meaning the cri<strong>si</strong>s impact over the growth and development of the Romanian enterprises in the<br />
actual conditions of the economic environment and also of the changes of logics that are imposed at European level.<br />
In this paper we wanted to show the importance of the costs of providing the necessary information to the<br />
management in order to take the best deci<strong>si</strong>ons in cri<strong>si</strong>s conditions. We con<strong>si</strong>dered the following objectives that an<br />
enterprise should have in the conditions of an unfavourable economic environment: the importance of the costs with<br />
the wages in the cost structure of the enterprise, the analy<strong>si</strong>s of the hidden costs, the investment policy in cri<strong>si</strong>s<br />
conditions, the expenses with financing on short term, the readjustment of the commercial contracts and limiting the<br />
expenses with external labour conscription, the sales growth policy by diminishing the adverti<strong>si</strong>ng expenses, the<br />
theme of qualifying the work force by starting national programs of work force reconver<strong>si</strong>on.<br />
Cri<strong>si</strong>s periods have their own characteristics. The first and the most important is the fact that they produce<br />
big changes. These changes don’t appear when an economy works at full speed ahead, when new jobs are available<br />
and wages grow from year to year, because when we are dealing with a po<strong>si</strong>tive economical dynamic it is hard to<br />
believe that there is a motivation for important measures. The cri<strong>si</strong>s is more suitable to drastic deci<strong>si</strong>ons. These are<br />
the moments when constraints and pressures appear and especially when the most important and tough questions are<br />
raised, questions that require categorical answers. These are tough times and ignoring them and smoothening their<br />
answers - although the cri<strong>si</strong>s demands them - are the mistakes of troubled times. These are trains of big changes that<br />
pass only once through the station.<br />
Under the double-effect of the pressure coming from the competition and the world financial cri<strong>si</strong>s, the<br />
enterprises feel the need to understand better their costs in order to determine with maximum preci<strong>si</strong>on the selling<br />
prices and the limits that can be achieved for each product. It’s not only about previ<strong>si</strong>on, there should also be<br />
con<strong>si</strong>dered the necessary ways in order to achieve the goals. That’s how we can explain the development of the<br />
today’s managerial control and of its favourite instrument, the analytic accounting of which no enterprise in Romania<br />
or Europe could be spared, and this is because behind the demand and offer of all price-competition there lies,<br />
indirectly, the cost-competition.<br />

As a consequence, to calculate, monitor and control costs represents only one of the aspects of performance<br />
of which we are going talk about in this study. To manage costs involves organizing a managerial accounting that<br />
should allow the calculation, analy<strong>si</strong>s and reporting of these costs according to the needs of the management.<br />
Managerial accounting should not solve only operative and operational aspects related to costs, but also strategic<br />
aspects related to the mis<strong>si</strong>on and vi<strong>si</strong>on of the enterprise. Therefore, we believe that it would be necessary to<br />

organize a Strategic Managerial Accounting, mainly due to the need for establishing some viable strategic goals<br />
integrated into the market demands. These goals should take into account the existing and potential competitors.<br />
The calculation of process costs (Activity-Based Costing or ABC ) is one of the last achievements in the cost<br />
calculation domain. Its origin is in U.S.A. Its base is con<strong>si</strong>dered to be the „The hidden factory” paper, written and<br />
published by Jeffrey G. Miller and Thomas E. Vollmann. The two authors submitted the sectors and the places of<br />
common costs (indirect) to a critical study, reaching the conclu<strong>si</strong>on that the crucial step in indirect cost control<br />
include the elaboration of a model that details and structures the causes of these costs. The first attempt of achieving<br />
such a new system in costs calculation was made in 1987 by Kaplan, Cooper and Johnoson.<br />
We con<strong>si</strong>der as causes of u<strong>si</strong>ng the process costs method in the conditions of world economic cri<strong>si</strong>s, the<br />
following:<br />
1) changes of the strategic po<strong>si</strong>tion of the company;<br />
2) changes in the demand for information for management;<br />
3) deficits of the calculation systems for the existing costs.<br />
1) Changes of the strategic po<strong>si</strong>tion of the enterprise<br />
The strategic po<strong>si</strong>tions of the enterprises have changed a lot because of the economic cri<strong>si</strong>s. This happened<br />
due to the changes occurred in the organization’s environment. These changes were influenced by the neces<strong>si</strong>ty of<br />
keeping the enterprise on the market although the purcha<strong>si</strong>ng power has decreased. This was done by forgoing shortterm<br />
financing for the consumption needs of the population. Due to the sharpening of the competition on the market,<br />
there is a tendency to reduce costs, improve product’s quality and develop new products and therefore the life of the<br />
products is shortened.<br />
Because of these reasons, the <strong>si</strong>ze and the importance of the indirect and common costs sectors grows<br />
compared to that of the production sectors. These modifications of activities contribute to the modifications in the<br />
costs structure, the importance of the individual direct costs decreases in the favour of the common indirect costs,<br />
and this happens in the same time with the growth of the fixed costs.<br />
2) Changes in the demand for information for management<br />
Within the enterprise’s deci<strong>si</strong>ons, in the foreground, lie new aspects, like:<br />
- Preparing and providing information about costs, related to a multitude of objects of costs calculation;<br />
- Reducing of the manufacturing batches <strong>si</strong>zes;<br />
- Determining an optimal number of the types of products;<br />
- Determining the costs for specific orders;<br />
- Controlling the economic effectiveness in the most important sectors of the indirect common costs.<br />
The necessary information refers to the entire value creation chain in an enterprise, including all the production<br />
sectors and auxiliary activity sectors. Also it is essential that managers concentrate on both the internal and external<br />
factors of the organization. We believe that the most important objectives in costs control management are the<br />
following (the objectives were selected after an analy<strong>si</strong>s of the accounting literature):<br />
To provide information for strategic planning - information about competition, strategy, external factors and<br />
internal performance;<br />
To provide information for strategic control and to measure financial and non-financial performance;<br />
To give information for benchmarking;<br />
To provide information about the products and about the lifecycle of the products.<br />
All organizations should prepare a strategic plan based on a modern approach: to analyze the markets, the<br />
competition and the external environment, and after doing this, to set the objectives. The key point of a strategic plan<br />
is the external analy<strong>si</strong>s because the environment (economic, social and cultural) influences the objectives. In our<br />
opinion, the external factors that should be analyzed are: interest rate, exchange rate, socio-cultural factors,<br />
technology, competitive environment, the sustainable development of the frame work etc. It is important for<br />
managers to know how these factors act because they must respond to the environment by:<br />
Introducing quality programs and calculating costs and revenues;<br />
45
Controlling the production process more efficiently, eliminating losses and inventory and reducing different<br />
costs (acqui<strong>si</strong>tion, production, total);<br />
Organizing a total quality management (TQM) and calculating the quality cost;<br />
Controlling the product lifecycles and applying a life-cycle costing method;<br />
Introducing a Kaizen Costing Process and managing the cost;<br />
Changing the structure of the bu<strong>si</strong>ness with a more decentralized one and calculating the performance for<br />
each manager so that their activity should be appreciated.<br />
3) Deficits of the calculation systems for the existing costs<br />
The traditional systems of cost calculation are oriented towards the actual production sectors. The common<br />
indirect costs are distributed in the products through some reference <strong>si</strong>zes. Discounting indirect costs is done by<br />
adding more in some value <strong>si</strong>zes.<br />
This indirect costs allocation is not complying with the opportunity principle, and this can lead to wrong<br />
strategic deci<strong>si</strong>ons.<br />
We will continue with the presentation of a study which compares the traditional costs calculation methods<br />
and the modern costs calculation methods.<br />

- production cost per unit: 5.570,25/600 = 9,284 RON<br />

- for product B: 9,284 + 20%Y = Y; B = 11,605 RON<br />
3) The result is: (9,468 – 7,574) x 400 + (11,605 – 9,284) x 600 = 2.150,2 RON – Profit.<br />

Regarding this, it can be appreciate that, by destination, the process costs calculation is directed by longterm<br />
deci<strong>si</strong>ons and can be con<strong>si</strong>dered a support for strategic bu<strong>si</strong>ness issues. The whole functional body of an<br />
enterprise is represented by activities and processes, the processes being po<strong>si</strong>tioned under costs report, horizontally<br />
related to the traditional splitting of the places of the costs.<br />
ABC Method is the result of some research supported by:<br />
the need to eliminate waste;<br />
identifying cause-effect relationship between costs and products;<br />
rational allocation of expenditure on products, not u<strong>si</strong>ng a global and imprecise manner;<br />
integration in the cost calculation of the differences on spending imposed by customizing products.<br />
The ba<strong>si</strong>c principle of the ABC method is: activities consume resources and products consume activities. ABC<br />
method determines the cost of the product by con<strong>si</strong>dering the activities that take place when it’s manufactured,<br />
offering in this way the advantage of a more real cost. With the help of this cost strategic deci<strong>si</strong>ons can be made.<br />
The ba<strong>si</strong>c premises of ABC method, in fact the logic behind this method is the following:<br />
Cost objects consume activities;<br />
Activities consume resources;<br />
The consumption of resources is one that generates costs;<br />
Understanding the causal relationships is the ba<strong>si</strong>s of a successful management.<br />

ABC method focuses over a production cycle, starting from the premise that for the production of a cost object some<br />
activities are executed, activities which in turn are consume resources.<br />
This method recognizes causal relationship between activities and the occurrence of costs.<br />
ABC method is used in cost management and in performance management. Performance means efficiency,<br />
effectiveness and economy. (EEE)<br />
The traditional method involves the following steps:<br />
Determining the production cost = direct expenses + indirect expenses of production<br />
Determining the completely commercial cost = production cost + general administrative expenses + selling expenses<br />
1) The total of direct expenses = 2.000 + 3.600 = 5.600 RON<br />
2) Allocation of indirect expenses:<br />
- calculating the additional coefficient:<br />
Ks =2.200 / 5.600 = 0,39<br />
- calculating the shares of allocation on products:<br />
A: 2.000 x 0,39 = 780 RON<br />
B: 3.600 x 0,39 = 1.420 RON<br />
Total: 2.200 RON<br />
3) Allocation of general administrative expenses:<br />
- calculating the additional coefficient:<br />
Ks =500 / 7.800 = 0,06<br />
- calculating the shares of allocation on products:<br />
A: 2.780 x 0,06 = 166,8 RON<br />
B: 5.020 x 0,06 = 333,2 RON<br />
Total: 500,0 RON<br />
4) Allocation of sales expenses:<br />
- calculating the additional coefficient:<br />
Ks = 300 / 7.800 = 0,04<br />
- calculating the shares of allocation on products:<br />
A: 2.780 x 0,04 = 111,2 RON<br />
B: 5.020 x 0,04 = 188,8 RON<br />
Total: 300,0 RON<br />
5) The complete commercial cost:<br />
Table nr. 4.<br />
Calculation article A B<br />
Direct expenses 2.000 3.600<br />
Indirect expenses of production 780 1.420<br />
Production cost 2.780 5.020<br />
General administrative expenses 166,8 333,2<br />
Sales expenses 111,2 188,8<br />
Complete commercial cost 3.058 5.542<br />
Quantity 400 600<br />
Complete commercial cost per unit 7,645 9,237<br />
50
6) Selling price:<br />
- for product A: 7,645 + 20%X = X; A = 9,556 RON<br />
- for product B: 9,237 + 20%Y = Y; B = 11,546 RON<br />
7) The result is: (9,556 – 7,645) x 400 + (11,546 – 9,237) x 600 = 2.149,8 RON – Profit<br />
CONCLUSIONS:<br />
Started through <strong>si</strong>gnals more or less shy 2 years ago, especially within the USA economy, the world<br />
financial cri<strong>si</strong>s, with direct and indirect repercus<strong>si</strong>ons upon the world and national economies, is no longer something<br />
new. Small and large companies, players from all areas of activity – from world-class ones (giants/symbols of<br />
national economies of the most developed states in the world) to the small investors, <strong>si</strong>mple citizens – from the<br />
richest to the poorest – began to feel the negative effects caused by the international financial cri<strong>si</strong>s.<br />
Many companies went bankrupt, some have temporarily suspended their activity, others have reduced their<br />
workforce – increa<strong>si</strong>ng unemployment, decrea<strong>si</strong>ng of the purcha<strong>si</strong>ng power and reducing the demand of goods from<br />
luxury to consumer.<br />
At least the next 4-6 months will continue to be characterized by incertitude, but managers will have to<br />
make deci<strong>si</strong>ons that will influence both short term results and medium/long-term bu<strong>si</strong>ness development potential.<br />
The price is a market and a reality instrument, which under the requirement of linking the demand and the<br />
offer, obtains a complex character. This character, in the context of the actual world economic cri<strong>si</strong>s, is magnified by<br />
the market characteristics in which it manifests and by the legislative framework that regulates the formation of<br />
prices, itself perfectible.<br />
The price of a good or a resource is an item that shows what you must give in order to obtain that good or<br />
resource.<br />
The reduction of the production cost determines the stability or even the reduction of the prices, the increase<br />
in the products competitiveness in the competition battle on the national market as well as on the external market.<br />
In order to reduce costs, the manufacturer must seek and find the reserves to reduce the consumption of<br />
production factors, to act <strong>si</strong>multaneously in all the compartments of the enterprise, on all the production factors, in all<br />
the phases of the economical activities and to apply the pos<strong>si</strong>ble measures to diminish costs in compliance with the<br />
requirements of the competition imposed by the market.<br />
The reduction of the production cost should have place without negative influences over the quality of the<br />
material goods and services, but, on the contrary, it should ensure a growth of quality. Reducing the costs by<br />
reducing the quality is anti-economical. The general trend imposed by the market competition is that the economic<br />
assets to incorporate in their costs less raw materials, high quality work, and to be obtained with the most modern<br />
technology.<br />
The careful choice of the elements and results that the analytical accounting users need is imposed. The<br />
users must always follow two fundamental principles: – several<br />
<strong>si</strong>gnificant figures are more efficient than a voluminous documentation that can’t be consulted because of lack of<br />
time; – an approximate but sufficiently accurate information, rapidly obtained, is often<br />
more useful than a precise information known later. ��¤�¢£��£�¨¤��¢¤¨¤�©��¤ ��¤�¢£��£�¨¤����¤��¢¤���¨����£��£�£�©�£��<br />

Abstract<br />
The current economic environment is characterized by uncertainties related to price volatility, difficulties in the<br />
valuation of financial instruments, as well as of assets and liabilities in general. More and more companies face<br />
liquidity issues that could even threaten their existence. Under these circumstances, saving such companies becomes<br />
a major concern for the ones directly interested, “survival” being the term most used in the current state of the<br />
world’s economy.<br />
In the context of this economic turmoil at international level, the main stakeholders and the accounting profes<strong>si</strong>onals<br />
find themselves in the po<strong>si</strong>tion of revi<strong>si</strong>ng their procedures, objectives, strategies, but also their behavior, their<br />
attitude in general, in order to limit or even eliminate the negative consequences of the financial cri<strong>si</strong>s. From our<br />
perspectives, the communication among company, stakeholders, and auditors represents the fundament of a<br />
successful bu<strong>si</strong>ness strategy. However, communication difficulties could be encountered, especially under conditions<br />
of uncertainty and cri<strong>si</strong>s.<br />
The present article intends to identify the opportunities and threats generated by the economic cri<strong>si</strong>s and to analyze<br />
the information flows among company, stakeholders and accounting profes<strong>si</strong>onals under circumstances in which the<br />
going concern assumption is threatened. Our paper empha<strong>si</strong>zes the importance of communication among company,<br />
stakeholders, and auditors in saving the firms affected by the economic cri<strong>si</strong>s.<br />

Introduction<br />
The break-out of the world economic cri<strong>si</strong>s, which has initially started with a financial cri<strong>si</strong>s, caused by<br />
unprecedented increases in credits (stimulated by a long period of moderate financial and economic conditions) is<br />
opening the road to changes affecting companies, stakeholders and the relationships between them, as well as to<br />
changes at the level of the whole society. These changes are rather answers, reactions, effects of the adaptation to the<br />
new unfavorable economic background. Usually, change involves multiple, ample, long processes, that are necessary<br />
for survival within new economic coordinates and which use specific tools, whereas one of the most important is<br />
communication.<br />
Our paper presents the current <strong>si</strong>tuation and the causes of the economic cri<strong>si</strong>s, aspects related to corporate<br />
governance and the role of the stakeholders in the enterprise’s life and the economic environment, but also the<br />
reaction of the stakeholders to the current economic changes. Last but not least, we presented the role and<br />
importance of communication in times of financial cri<strong>si</strong>s, as main survival factor and even exit from the cri<strong>si</strong>s.<br />
1. Current Situation and Causes of the Economic Cri<strong>si</strong>s<br />
The financial cri<strong>si</strong>s that broke out in the summer of 2007 is striking in its magnitude, its speed of spreading<br />
internationally and in its per<strong>si</strong>stence, <strong>si</strong>nce it is far from being over. At present, the financial world is characterized<br />
by risk adver<strong>si</strong>ty, reduced liquidity, price volatility, uncertainty regarding the future of financial institutions, doubts<br />
53
elated to the quality of the structured credit products and uncertainty about the macroeconomic prospective in<br />
general. A number of factors contributed to the break out of the current economic cri<strong>si</strong>s, among which: the<br />
expan<strong>si</strong>onary macroeconomic policies of the United States of America to restore the economic growth affected<br />
during the previous cri<strong>si</strong>s from the first half of the century, exces<strong>si</strong>ve distribution of credit, the use of complex<br />
financial instruments without having realistic image on the associated risks etc. Some authors also mention lack of<br />
2008,<br />
economic cooperation between major countries (�¤��¢�����¤�£�©��£©¨�¢£�£�<br />
p. 3).<br />
This turmoil in the most advanced financial markets was the consequence of an exceptional growth of credit,<br />
stimulated by a long period characterized by benign financial and economic conditions. During that period, there<br />
were extremely low real interest rates, whereas no liquidity problems existed, which raised the level of risk that<br />
creditors, investors and intermediaries were willing to take on. In conjunction with this, financial innovations<br />
expanded the system’s capacity to generate credit assets and leverage but outpaced its capacity to manage the<br />
2008, ©¢£¤�©��¦���£�§�£��©¨�¤�£¨£¤��¤ ��¢§������©��£��<br />
associated risks. (�¤��¢�����¤�£�©��£©¨��©�£¨£�<br />
p.<br />
5). A sophisticated and apparently stable system was established, which con<strong>si</strong>sted in originating extremely complex<br />
financial instruments that allowed banks to offload risks (especially in the United States of America). These financial<br />
instruments were then distributed and bought – mostly in Europe, without paying proper attention to the underlying<br />
2008,<br />
assets and the real economic fundament of these instruments. (�¤��¢�����¤�£�©��£©¨�¢£�£�<br />
p. 3).<br />
The expan<strong>si</strong>on of complex financial instruments was also encouraged by favorable credit ratings that implied assets<br />
were high-quality and low-risk. Financial guarantors contributed further to the perception that investment<br />
opportunities were unlimited and of high quality. As a consequence, the perceived liquidity of credit instruments<br />
increased. Additionally, several factors led to lowering the standards used in analyzing the eligibility of clients who<br />
wanted to benefit from the products of the financial institutions. Some of these factors were: relatively stable<br />
macroeconomic conditions, increased competitiveness among financial institutions, low interest rates, ri<strong>si</strong>ng house<br />
prices, weak government over<strong>si</strong>ght. Thus, the products of the financial institutions (in particular credits) were given<br />
much ea<strong>si</strong>er, and this lead in some cases to fraudulent practices<br />

Despite that, neither investors nor banks, and not even rating agencies correctly assessed the risks associated with<br />
this kind of financial instruments that deterioration in general economic conditions would pose (�¤��¢�����¤<br />
p. 5). Standard risk management ©¢£¤�©�� ��¢§������©��£��<br />
instruments used by financial institutions were not appropriate in estimating the impact of potential losses connected<br />
to structured credit products. The absence of a history of returns, the complexity of many of these products created<br />
2008, ¦���£�§�£��©¨�¤�£¨£¤��¤<br />
uncertainty regarding estimated risks (�¤��¢�����¤�£�©��£©¨��©�£¨£�<br />
p. 7). Market participants underestimated default risks, market risks and liquidity risks.<br />
In some banks, the control over off-balance sheet risks, as well as the communication across bu<strong>si</strong>ness lines and<br />
functions was weak. As a result, when turmoil began, most companies, investors, other stakeholders, as well as the<br />
society as a whole were not able to correctly and rapidly assess risk exposure. The stakeholders’ role is very<br />
important in conjunction with risks, because they have enough instruments for saving the companies and the<br />
economic environment from the imminent “disasters” that could be the consequences of the world’s economic cri<strong>si</strong>s.<br />
2. Corporate governance and the role of stakeholders in the company’s life and in the economic environment<br />
In theory it is con<strong>si</strong>dered that the concept of enterprise refers to a <strong>si</strong>ngle entity which operates harmoniously and<br />
whose main goal is to maximize value and shareholder wealth. Due to the appearance of new elements and complex<br />
needs, other views on the enterprise have been developed. Thus, the definition of the enterprise could be based on the<br />
concept of social interest, with the purpose of generating wealth as a result of the participant’s collaboration in the<br />
company’s life (shareholders, managers, creditors, employees, customers, suppliers, public power). Thus, the<br />
objectives of a company are of social nature, but also relate to maximizing profits. (Feleagă N. 2006, p. 69). The<br />
definition developed under the first theory leads to financial information directed towards investors, while the second<br />
definition is oriented to satisfy the financial needs of all users (Feleagă N. 2006, p. 69).<br />
One of the key factors that influence the efficient use of resources, the increase of the confidence shareholders have<br />
in the enterprise managers, the success in achieving the company’s objectives and the economic efficiency is the<br />
corporate governance system by which a company is controlled. This system promotes fairness and transparency at<br />
company level, and con<strong>si</strong>sts in a set of rules of conduct that aims the welfare of the society as a whole, but mostly the<br />
welfare of the shareholders and other stakeholders: managers, creditors, employees, customers, suppliers, public<br />
power, etc. (¡�¢¨��©�£, 1998,7).<br />
54
Shareholders, one of the key elements of the company, bring the funds necessary for the activity, and are in turn<br />
interested that these funds are used and managed well and fairly by the managers appointed for this purpose. The<br />
relationship between owners and managers is controver<strong>si</strong>al, because the two categories of participants may have<br />
different interests, often contradictory. For example, the shareholders have, in general, a greater preference for risk,<br />
because their securities portfolio is diver<strong>si</strong>fied, while managers are more risk-adverse, because all financial interests<br />
and of other nature focus on a <strong>si</strong>ngle enterprise (Feleagă N. 2005, p. 171).<br />
Agency theory, by which the company is seen as "a knot of contracts" (Feleagă N. 2005, p.51), is the one that makes<br />
it pos<strong>si</strong>ble to solve "the conflict of interests between the shareholders and the managers of an enterprise" (Feleagă N.<br />
2005, p.170). This theory establishes a set of relationships, with mutual benefits, on the one hand, between<br />
shareholders and managers, but also between other parties interested in the smooth running of the company<br />
(employees, creditors, etc.). However, the shareholders-managers relationship is the one that generates the most<br />
complex conflicts of interest and settling them is closely related to the organization of an effective system of<br />
governance which "encourages that the interests of the managers are aligned to the ones of the shareholders"<br />
(Feleagă N. 2005, p. 170).<br />
Stimulating managers so that they fulfill their respon<strong>si</strong>bilities with fairness refers in principle to financial benefits<br />
(salary, implementation of a stock-option plan that creates benefits such as dividends and increases of value<br />
generated by the sale of the company’s shares), but also to benefits in kind (company car, company house, etc.).<br />
Auditors play an important role in the conflicts of interest between shareholders and managers. They make a fair,<br />
impartial, independent evaluation of the financial statements of the enterprise, having the role of showing<br />
shareholders the real <strong>si</strong>tuation. Through external audit, shareholders benefit from an important tool to assess the<br />
efforts of managers in achieving the company’s goals, and in maximizing the wealth of owners.<br />
Creditors are third parties who provide loans to companies, and look out for interest and principal. Thus, creditors are<br />
directly interested in that company obtains profit as this will be the source of payment of the related loan interests.<br />
As for the shareholders, the loans can be a viable solution for obtaining new funds, but the associated risk may be<br />
high, because the effective administration of the equity thus obtained depends on the attitude, skills, and especially<br />
on the interest of the manager.<br />
Employees have multiple interests within a company. They represent one of the most important resources available<br />
to a company. The main interests of the employees concern the remuneration level, the benefits in kind (meal and<br />
gift tickets, phone, life insurance, trips, company car, etc.), the security and the work conditions etc. For this purpose,<br />
the employees follow the evolution of profitability and the bu<strong>si</strong>ness continuity of the company.<br />
Customers and suppliers are the trading partners of the company. Customers are interested in the ability of the<br />
company to continue its activity and in its prices, because they are directly interested whether their supplier can<br />
provide to them the goods/services they need for the smooth running of the activity. Suppliers have in view whether<br />
the customer-company has sufficient resources to pay its financial debts (Feleagă N. 2005, p. 57).<br />
The corporate governance system may differ depending on the importance given to the categories of participants, but<br />
the relationship between shareholders and managers occupy the central po<strong>si</strong>tion, as their relationship has the most<br />
divergent elements.<br />
3. The Impact of the Current Financial Cri<strong>si</strong>s on the Main Stakeholders and Accounting Profes<strong>si</strong>onals<br />
3.1. Managers, Investors and Auditors<br />
Managers are the ones who, by u<strong>si</strong>ng a series of laws, principles, methods etc., as well as their own competences and<br />
abilities, run the company towards achieving its established purposes. They are charged by investors with u<strong>si</strong>ng the<br />
company’s resources (from equipment to employees’ knowledge and competences) in order to achieve bu<strong>si</strong>ness<br />
success. For investors, who took financial risks, success means, in most of the cases, financial performance, namely<br />
profit. However, the objective of maximizing profit set by investors is not always the objective of the managers, who<br />
are often tempted to follow their own interest, at the expense of the investors. Under financial cri<strong>si</strong>s, managers and<br />
investors focus more on their own interests, sometimes oppo<strong>si</strong>te to one another. However, it may happen that the<br />
objectives of the managers and those of the investors are the same, <strong>si</strong>nce both are interested in survival and exist<br />
from the cri<strong>si</strong>s.<br />
Since investors do not always have the benefit direct contact to the respon<strong>si</strong>ble managers, the ones that act instead of<br />
them and protect their interests are the financial auditors. Financial auditors are independent experts that express<br />
their opinion on the financial statements of the companies, their interest being whether these statements provide a<br />
true and fair view. Under financial cri<strong>si</strong>s, the role of the external auditors has an increased importance, and banks and<br />
55
supervisors rely more and more on the expertise and judgment of external auditors. An audit conducted in<br />
accordance with international audit and ethics standards, under independence, integrity and profes<strong>si</strong>onal competence,<br />
2008, ©���©�££���§�¤¢�£�£��<br />
can provide a number of benefits to institutions, companies, financial systems and supervisors (���¤¢�©¨©§�£�¢§©¨£�<br />
p. 2).<br />
Audits increase the confidence of market participants by increa<strong>si</strong>ng the credibility of the financial statements,<br />
especially under economic turmoil. Although it is not one of their main objective, auditors can help identify<br />
weaknesses in internal control relating to financial reporting and thus can contribute to safe and sound bank systems.<br />
Most of the world’s credit institutions undergo audits, and supervisors rely more and more on high quality bank<br />
audits that complement the supervisory processes. In the context of globalization, most audit companies expanded at<br />
international level, and consequently, their structures are complex and corporate governance within audit companies<br />
is characterized by difficulties in insuring transparency 2008, p. 8).<br />
Therefore, the audit profes<strong>si</strong>on faces new challenges within the current financial cri<strong>si</strong>s. ©���©�££���§�¤¢�£�£�� (���¤¢�©¨©§�£�¢§©¨£�<br />
One of these challenges refers to testing the going concern assumption, which is fundamental in preparing financial<br />
statements. Most of the financial statements are prepared based on the assumption that the entity is continuing in<br />
bu<strong>si</strong>ness for the foreseeable future with neither the intention nor the neces<strong>si</strong>ty of bankruptcy, liquidation or reducing<br />
activity (ISA 570). The auditor is in charge with verifying the appropriateness of this statement made by<br />
management, as part of its respon<strong>si</strong>bilities to prepare the financial statements of the company. Under economic cri<strong>si</strong>s,<br />
it is expected that more and more companies put question whether they will indeed continue as going concern in the<br />
foreseeable ��£������¤¢�£���¤�§¢¢¤��������£����£¢���¤��2009, future (which usually means over a period of more than 12 months)<br />
p. 5). As a consequence, the auditor will need to pay<br />
particular attention in conducting the specific tests related to this aspect.<br />
Before the financial cri<strong>si</strong>s, auditors had a relatively pas<strong>si</strong>ve role, because they analyzed the evidence on which the<br />
management made the going concern assumption and investigated the soundness of this evidence. Nowadays,<br />
auditors are challenged to take a more active role, to search in an alert and independent manner the factors that could<br />
dismiss the management’s assumption and that could lead to issuing an adverse opinion. Another challenge for these<br />
accounting profes<strong>si</strong>onals is auditing financial statements based on fair value measurement. Both measuring fair value<br />
and verifying this measurement is difficult due to its complexity and involves subjectivity and uncertainty, especially<br />
under cri<strong>si</strong>s. Therefore, the auditor will need to develop his/her competences in order to adapt to the new <strong>si</strong>tuation.<br />
3.2. Creditorii<br />
The need for funding of a company can be satisfied through loans from bank lenders, from companies within the<br />
group etc. To determine the ability of reimbursement of the loans, the bank lenders take into account the fair value of<br />
the items, not the historical value. The prudence that they manifest may conduct to an undervaluation of the assets<br />
and an overvaluation of the debts in order to ensure a safety margin (Feleagă N. 2005, p. 56).<br />
(�§�£�����£�¤¢©�£���£��¤��¤����<br />
Creditors assess the liquidity indicators of the companies funded, but also "the personal, technical, moral value of the<br />
managers, the general <strong>si</strong>tuation of the activity branch the enterprise is part of, the general <strong>si</strong>tuation of the company<br />
(the nature of products, the quality, the price, the customers, the suppliers) and the financial <strong>si</strong>tuation of the<br />
enterprise "(Feleagă N. 2005, p.56). Bank creditors document their lending deci<strong>si</strong>on according to the company’s <strong>si</strong>ze<br />
and closely analyze the evolution of loans reimbursement. However, due to non-compliance with the general<br />
principles related to loans, the imprudence of bank creditors led to the break-out of the global financial cri<strong>si</strong>s in 2007.<br />
As a normal reaction, in times of financial cri<strong>si</strong>s, the attention of bank creditors grows <strong>si</strong>gnificantly. While in normal<br />
conditions, prudence is the ba<strong>si</strong>c principle, during financial cri<strong>si</strong>s, lenders focus on exces<strong>si</strong>ve prudence, on bu<strong>si</strong>ness<br />
continuity of companies, on their ability to maintain profits, on the degree of liquidity, but also on the human factor,<br />
especially on managers, on their behavior, the measures taken to survive, and also to exit the cri<strong>si</strong>s.<br />
The refusal of bank creditors to fund a company can lead to a liquidity cri<strong>si</strong>s. The permanent communication<br />
between creditors and managers, the fair description of the company’s <strong>si</strong>tuation, the flexibility, the transparency and<br />
the fairness are key factors for establishing a viable relationship between creditors and companies. In cri<strong>si</strong>s<br />
conditions, survival is the main objective of the companies and funds are primary. However, if loans are not<br />
efficiently used, it can lead to bankruptcy.<br />
During difficult economic conditions, the loans from companies within the group represent a reliable alternative. The<br />
conditions for obtaining such loans may be more permis<strong>si</strong>ve, the interests – lower, or the reimbursement periods –<br />
longer. However, the funding alternative is available only to larger companies, who are part of a group of enterprises.<br />
3.3. Other stakeholders – employees, customers, suppliers<br />
3.3.1. Employees<br />
56
Survival remains the biggest challenge in times of financial cri<strong>si</strong>s. However, survival is understood in different ways<br />
by the managers and the employees of a company. If managers believe that survival means reducing the number of<br />
staff, for sure, the employees will think exactly the oppo<strong>si</strong>te, because the disposal would affect their welfare, as the<br />
unemployment period may be longer than normal. On the other hand, accepting a number of employees too large in<br />
comparison with the neces<strong>si</strong>ties of survival or continuation of activity can lead to inefficiency and even bankruptcy.<br />
In cri<strong>si</strong>s conditions, the employees are interested not to lose their job, and to maintain the same financial and other<br />
benefits. Therefore, the permanent communication with their managers, the active participation in the bu<strong>si</strong>ness of the<br />
company, or on the contrary, the more or less violent confrontations between managers and employees are some of<br />
the pos<strong>si</strong>ble effects related to the reaction of employees during these difficult conditions.<br />
3.3.2. Customers and suppliers<br />
Trading partners demonstrate more prudence when there are going concern issues. Customers are mainly interested<br />
in the company’s going concern assumption, but they also have in mind the pos<strong>si</strong>bility of negotiating prices ea<strong>si</strong>er.<br />
On the other hand, the suppliers are interested and analyze more strictly the profitability of the companies and their<br />
ability to pay the financial liabilities. However, the monitoring of debits and deadlines is the main objective of<br />
suppliers in times of financial cri<strong>si</strong>s. The improvement of the relationships between the trading partners and the<br />
companies can be achieved through communication and informational transparency.<br />
The financial cri<strong>si</strong>s leads to <strong>si</strong>gnificant changes in the behavior of stakeholders. The reactions differ depending on<br />
the role of the participants in the company’s life. To avoid bankruptcy and conflicts of interest, managers should<br />
adopt a flexible attitude, adapt to the demands of the stakeholders involved and not at last, insure permanent<br />
communication between company and interested parties.<br />
4. Importance of communication under economic cri<strong>si</strong>s<br />
Most economic cri<strong>si</strong>s lead to rumors, to distorted perceptions regarding the economic environment, to stress, to lack<br />
of control, to panic, to disorientation, to uncertainty, to lack of security and even to major lack of balance in the<br />
whole society. The first affected by the above mentioned facts are companies, their owners and managers, but also<br />
other stakeholders and parties directly involved in the life of a company. They may have reactions such as denial,<br />
avoidance of respon<strong>si</strong>bility, disclaimer of culpability, justification. Finally, the reactions are transformed into<br />
po<strong>si</strong>tive ones: acceptance, remediation, corrective actions, optimism and confidence. One of the factors that make the<br />
tran<strong>si</strong>tion from a negative attitude on the cri<strong>si</strong>s to a survival-oriented behavior, if not to optimism, is the<br />
communication between the company and stakeholders and between the company and the economic environment as<br />
a whole (see figure 1).<br />
Individuals react differently to a given <strong>si</strong>tuation. Their personality, temperament, and the environment in which they<br />
have developed and worked, the psychological, social, economic, political factors and the factors of other nature<br />
have led to different, complex, sometimes opposed reactions. Social context involves individual’s interaction, which<br />
can be achieved mainly through communication. The role of communication is important because it can lead to<br />
sustainable and productive relationships between individuals or to the oppo<strong>si</strong>te reactions of rejection, conflict, and<br />
indifference. Human relationships influence the creation, the existence and the development of the enterprises, and of<br />
the economic environment. Companies can not exist without individuals, whereas a powerful connection is created:<br />
individuals depend on the existence and the proper functioning of companies, while companies cannot exist in the<br />
absence of individuals.<br />
The strong link that has been created between the different categories of individuals, due to the interactions between<br />
them, had as starting point communication. In times of financial cri<strong>si</strong>s, communication takes magnitude, <strong>si</strong>nce<br />
individuals need accurate information on the facts (in order to eliminate rumors and distorted perceptions of the<br />
economic environment). On the other hand, u<strong>si</strong>ng communication and tools offered by psychology, individuals can<br />
recover their balance (by eliminating stress, lack of control, panic and disorientation). Last but not least, the<br />
uncertainty, and the lack of security and balance can be controlled and removed only when panic and disorientation<br />
in the society are reduced. Thus, individuals can make correct and rational deci<strong>si</strong>ons related to the cri<strong>si</strong>s <strong>si</strong>tuation,<br />
can identify the causes, clear them off and restore the social and economic balance.<br />
For these reasons, correcting the negative effects triggered by the economic cri<strong>si</strong>s is the first step to getting out of the<br />
cri<strong>si</strong>s. However, the respon<strong>si</strong>bility for these actions is to be taken by individuals (stakeholders) whose main tool is<br />
communication.<br />

Conclu<strong>si</strong>ons<br />
The effects of the financial cri<strong>si</strong>s that broke out in the summer of 2007 at international level are also felt today. The<br />
uncertainty, the increa<strong>si</strong>ng number of cases of bankruptcy, the risk adver<strong>si</strong>ty of investors, the reduced liquidity, the<br />
stricter credit conditions, the price volatility are only some of the features of the cri<strong>si</strong>s phenomenon. All participants<br />
in the economic life are affected, directly or indirectly, more or less, by the current cri<strong>si</strong>s. As a consequence, changes<br />
are necessary, both in attitude, but also in the undertaken actions, whereas communication is essential as instrument<br />
of survival and exit from the cri<strong>si</strong>s.<br />
Managers, who are respon<strong>si</strong>ble for their company’s well-being, will need to develop survival strategies and powerful<br />
instruments of risk management. Moreover, prudence and conservatism will characterize the attitudes of investors,<br />
who before cri<strong>si</strong>s started, were willing to take risks. Creditor, who proved to be quite tolerant in the period of credit<br />
expan<strong>si</strong>on, will become stricter in analyzing the eligibility of their potential clients. The importance of auditors will<br />
increase, because creditors, investors and the public in general rely on their opinion as independent<br />

58
Employees will become directly interested in the success or failure of the company where they work, due to their<br />
dependency relationship with the employer. The driver for all these changes in attitude will be communication. �§�£�����£�¤¢©�£���£��¤��¤������£������¤¢�£���¤�§¢¢¤��������£����£¢���¤�������International<br />

<strong>IN</strong>TRODUCTION<br />
The primary objective of any company is to create value for its shareholders.<br />
Creating value has become extremely important in the financial world as a series of new<br />
indicators were developed for measurement.<br />
Creating value for shareholders tends to become a major criterion of performance analy<strong>si</strong>s at<br />
large companies. The applicability of this type of analy<strong>si</strong>s is very broad, covering companies<br />
listed on the stock exchange and unlisted companies. A company creates value if it earns enough<br />
to cover the cost of financial debt and the opportunity cost of capital.<br />

1. USE OF THE <strong>IN</strong>DICATOR TO CREATE VALUE: ECONOMIC VALUE ADDED<br />
(EVA)<br />
One of the most used indicators for asses<strong>si</strong>ng the <strong>si</strong>ze of the value created by a company is the<br />
economic value added (EVA). This indicator was developed by the consulting company Ster –<br />
Stewart, with the main role of measuring the financial performance achieved by a company.<br />
EVA is calculated as a difference between operating profit and net total cost of capital used. As<br />
Maria Niculescu (2005, p.194) says, EVA has become in the decade 1990-2000, a total standard<br />
of quality, being an indicator measuring performance of the management team but also a<br />
60
eference to substantiate and assess the effectiveness of deci<strong>si</strong>ons. The relationship for<br />
calculating the economic value added , by the consulting company Stern – Stewart is:<br />
EVA = Net operating result – Cost of capital invested<br />
Economic value added measures the wealth created by a company in a financial year. This<br />
indicator is calculated as cost of debt and equity costs. The most innovative aspect of the<br />
economic value added is that it present the level of income to which value is created. This is done<br />
because EVA is calculated after deducting the cost of capital. “U<strong>si</strong>ng economic value added as an<br />
instrument for allocating capital to benefit brings benefit not only at micro scale, but even at the<br />
macro level. The indicator produces an assessment of the effectiveness of capital allocation by<br />
con<strong>si</strong>dering the relationship between returns and risk. Therefore, the achievement of po<strong>si</strong>tive<br />
economic values is a <strong>si</strong>gn of efficient use of capital in terms of risk. "(Valceanu, G., Robu V.,<br />
Georgescu, N., 2005, p.320). A study conducted by Robert Kleineman (1999, pp.80-91) presents<br />
the case of companies in the United States that have adopted EVA in the period 1987-1996,<br />
which exceeded the performance of companies in the same industry. During the four years<br />
experience in the study, companies that used EVA had results that were 28.8% better than those<br />
that have not used the concept. Vernimmen et al. (2005, pp.355-356) presents the point of view<br />
through which the managers are judged on the ba<strong>si</strong>s of EVA, they will have a huge incentive to<br />
reduce capital invested. It is very pos<strong>si</strong>ble that this reduction is purely overvalued, and it doesn't<br />
have a real effect. This reduction of capital investment may lead to abandonment of investment<br />
that can bring important revenues in the future.<br />
The result is achieved through operational activities of the company, representing the result of<br />
operating. From the result of operation used in the calculation of EVA, it is deducted the<br />
depreciation and property tax, achieving the net operating result. The equivalent of the net<br />
operating result in Anglo-Saxon literature is Net Operating Profit After Taxes, abbreviated<br />
NOPAT.<br />
Capital investment required to calculate EVA is composed of equity and financial debts from<br />
participating to the co-financing of the economic activity. The cost of capital (weighted average<br />
cost of capital), according to Maria Niculescu (2005, p.195), is calculated as a weighted average<br />
of equity and financial debts. The term used in Anglo-Saxon literature bears the name of<br />
Weighted Average Cost of Capital (WACC), and is calculated as follows:<br />
Where:<br />
CPR is equity;<br />
Dat is the net financial debt;<br />
is the average cost of capital;<br />
is the average interest.<br />
The average cost of capital can be calculated based on the C.A.P.M. This is a rather widely seen<br />
and practiced model in the companies from countries with developed stock systems. This model<br />
was developed at the end of the years 1950-1960 with the contribution of Harry Markowitz,<br />
William Sharpe, John Lintner and Jack Treynor, and now it is a used and recognized model.<br />
61
The C.A.P.M model is based on the assumption that investors act rationally, and have all the<br />
information available.<br />
The cost of equity is determined as follows:<br />
Where<br />
Rf is the rate of interest without risk;<br />
Rm is the average rate of return of financial stock market;<br />
β is the sen<strong>si</strong>tivity coefficient of the title, compared with the average exchange<br />
(Rm-Rf) is the market risk premium (Rp).<br />
The interest rate risk is not practiced in the securities, while the coefficient β is obtained by<br />
statistical calculations and is between 0.6 and 1.4.<br />
The author Maria Niculescu (2005, p.196), specifies that a po<strong>si</strong>tive EVA indicator means creating<br />
wealth for shareholders over remuneration of capital. In contrast, a negative value indicates that<br />
the capital does not cover the cost of operating results achieved. "In other words, it loss money<br />
even if has po<strong>si</strong>tive accounting results". The same author presents the point of view of the famous<br />
economist Alfred Marshall in the year 1890: "What remains to a company from his winnings,<br />
after deducting the cost of capital at a rate corresponding can be con<strong>si</strong>dered a benefit of the<br />
developer or manager". Through the vi<strong>si</strong>on of integrative approach, EVA gives a fair picture of<br />
the efficiency of resource use and effectiveness of global bu<strong>si</strong>ness. As Peter Drucker said in<br />
1995, in an article published in the journal "Harvard Bu<strong>si</strong>ness Review", "measuring the value<br />
added after deducting all costs, including the capital, EVA shows the productivity of production<br />
factors, indicating the products, services, subunits or activities which productivity is con<strong>si</strong>derably<br />
higher and that creates a greater value added." (Niculescu, M, 2005, p.198).<br />
2. STUDY ON ECONOMIC ANALYSIS OF VALUE ADDED FOR 9 companies listed<br />
on the Bucharest Stock Exchange (BVB)<br />
2.1. The description of the methodology and analy<strong>si</strong>s of the implementation of the<br />
study<br />
In carrying out this study, we started with a set of nine of the 10 most liquid companies listed on<br />
the Bucharest Stock Exchange that build the BET index (first index developed by BVB,<br />
representing the reference index of capital market), with <strong>si</strong>gnificant weights in this index, as the<br />
table below shows.<br />

The study shows the economic value added of companies taking into account the information in<br />
period 2006-2008. The analyzed period is the beginning of the financial cri<strong>si</strong>s, which affected the<br />
financial sector worldwide, producing negative effects on financial markets and the listed<br />
companies. The financial cri<strong>si</strong>s, evidenced by the bankruptcies of companies in banking and<br />
financial sector but also by uncertainty among investors, is a very important moment for the<br />
economic and financial analysts because it is a period in which some theories can be cancelled,<br />
but also new economic-financial models can be confirmed. The current cri<strong>si</strong>s is caused by a<br />
sudden liquidity in global markets and banking systems, caused by the failure of companies that<br />
invested in mortgages with a high degree of risk. The cri<strong>si</strong>s revealed the weaknesses in the global<br />
financial system. During this period of uncertainty, a careful study of indicators of value creation<br />
is very important for taking deci<strong>si</strong>ons.<br />
Through information from the financial companies, but also additional information from annual<br />
reports, we have calculated indicators for earning Economic Value Added.<br />
2.2. Analy<strong>si</strong>s based on value creation<br />
Starting from the calculation of EVA, we calculated the net operational result of the 9 companies.<br />
So after deducting depreciation and property tax, we had net operating result. The net operating<br />
result based on the information from 31.12.2008 for the 9 companies are listed in the table below:<br />

We can notice a large net operating result for SNP Petrom with 1593013703 lei, and a negative<br />
net operating result for SSIF Broker with -9627678 lei. The results were obtained by adjusting<br />
the operating result.<br />
To determine the cost of invested capital we have started to determine the capital investment and<br />
the cost of capital.<br />
In the determination of the invested capital we took into account the equity, provi<strong>si</strong>on for risks<br />
and charges, deferred taxes, loans from bond issues, long-term loans and short-term loans.<br />
In this sense beginning from the financial year 2008, we obtained the following results presented<br />
in the table below.<br />

The capital invested is a very important <strong>si</strong>gnificance in the analy<strong>si</strong>s of EVA, representing the<br />
cash flow for advanced development of the company and for financing economic activities.<br />
In determining the cost of equity and borrowed (weighted average cost of capital) we started from<br />
the model outlined above:<br />
Studying the model, we arriving at the average cost of capital determined on the ba<strong>si</strong>s<br />
This model, developed by the C.A.P.M (Capital Assets Price Model) puts the spotlight on the rate<br />
Rf = risk free rate. This rate is identified with the yield of securities, whereas shows a very high<br />
64
security, as saying the authors: Dragota V. and Ciobanu, A. (2002, p.252). Moreover, the same<br />
authors present the coefficient volatility β as being defined as the sen<strong>si</strong>tivity of an asset to<br />
changes in value of the portfolio.<br />
β is a coefficient of elasticity which expresses the sen<strong>si</strong>tivity of a title to market changes. In<br />
other words, he shows how to change the price of a title change to a percentage of the market.<br />
(Michael Alexa, SSIF Broker, 2008, www.s<strong>si</strong>fbroker.ro)<br />
To determine the coefficient β is determined based on the clas<strong>si</strong>cal relationship for calculating<br />
the volatility:<br />
β =<br />
Where cov (Ri, Rm) is the co variation between firm profitability and the analyzed market, while<br />
the mean disper<strong>si</strong>on (variants) presents the yield market.<br />
Starting from these premises β have the following values:<br />

The coefficient β has different values between 0.79 (Azo) and 1.13% (BRD)., and it corresponds<br />
to the period 1 January 2006-29 August 2008.<br />
The risk free rate of return is 6% yield to securities related to the state in 2008. The return<br />
without risk is between the normal range for this type of efficiency.<br />
The market risk premium is determined based on the profitability of the market. I<br />
con<strong>si</strong>dered as a guideline the BET index of the Stock Exchange from Bucharest. In this aspect<br />
65
starting from the daily percentage changes BET index for the period 1 January 2006 - 29 August<br />
2008, we achieved a return of -0.02% of the market. Adjusting the market with the first return of<br />
risk related to country risk (2.03%), and subtracting the rate of return without risk (6%), we came<br />
to a risk premium of -3.99% of the market.<br />
In this aspect the average cost of capital<br />

The cost of invested capital (weighted average cost of capital) is determined according to the<br />
model<br />
The interest rate for lending was set at 14.25% and the rate of tax is 16%.<br />
Starting from these data, the cost is fixed cost of equity and debt for each company listed<br />

In 6 of the 9 companies analyzed, there is a negative economic value (disposal value) as a result<br />
of achieving a rate of return on invested capital (after taxation) less than the weighted average<br />
cost of capital used by the firm. According to the table above, a comparison between the rate of<br />
return of capital invested and the weighted average cost of capital, leads to a result of creating<br />
value or destroying value.<br />
It notes that the SNP Petrom creates the greatest value added by 1052630261 lei, while BRD<br />
created a negative value. Moreover, Tran<strong>si</strong>lvania Bank has obtained a result of -1776988262 lei.<br />
The financial sector is in a period of high instability, therefor are necessary the investments in<br />
developing new lines of bu<strong>si</strong>ness. This can be explained so that this destruction of value in the<br />
two banks is the result of the cost of capital over net operating result as a result of investments<br />
made. The same <strong>si</strong>tuation encountered in the case with SSIF Broker with -11981274 lei.<br />
The energy sector represented in this study Transelectrica of SNP Petrom and Rompetrol,<br />
Rafinarie Constanta that presents different <strong>si</strong>tuations. Thus if the SNP Petrom create value, both<br />
RRC and TEL created negative value, on the investment fund in 2008.<br />
Biofarm Bucharest has created economic value added amounting to ROL 7385936, following a<br />
rate of return on invested capital (after tax) of 8.36%, higher than the weighted average cost of<br />
capital of 3.26%. Azomures registered a rate of return on invested capital of 11.82%, being the<br />
highest rate of the analyzed portfolio. Weighted average cost of capital was at a <strong>si</strong>ze of 4.75%.<br />
CONCLUSIONS<br />
"In recent years, a new reality raises capital providers, the management company and financial<br />
analysts: the need to manage the amount and orientation of the primary strategy to create value<br />
for shareholders." (Valceanu, G., Robu V., Georgescu, N., 2005, p.334)<br />
Under conditions of high instability, the use of many indicators for the performance analyses,<br />
including the use of indicators of value creation may lead to different results from clas<strong>si</strong>cal<br />
analy<strong>si</strong>s. Thus all the deci<strong>si</strong>on makers will have a picture of the value created by bu<strong>si</strong>ness, by<br />
comparison of the operating result and net cost of capital invested. Net operating result shows the<br />
operational activity (operating) and the level of development.<br />
U<strong>si</strong>ng the methodology of calculating of the cost of capital invested, we can follow the evolution<br />
of indicators such as capital cost or cost of debt. These indicators can provide detailed<br />
information for analyzing phenomena track. "The economic value added is a strategic and<br />
effective in the measurable financial performance management company that can be used in the<br />
incentives process to increase economic efficiency. (Valceanu, G., Robu V., Georgescu, N.,<br />
2005, p.322). Thus, as the authors stated (Işfănescu A., V. Robu, Anghel I. (2001, p.225) it can<br />

ABSTRACT<br />
This paper presents the financial and economic coordinates of corporate governance models applied in developed<br />
countries and the role of internal audit as a governance mechanism used in mergers and acqui<strong>si</strong>tion processes.<br />
Mergers and acqui<strong>si</strong>tions are not performant by chance. Performance is based on financial management principles,<br />
value adding objectives, and advantage and synergy arguments. These can be assessed in view of M&A deci<strong>si</strong>ons<br />
through internal control and internal audit evaluations. Internal audit mis<strong>si</strong>ons can be achieved before and after the<br />
merging process and take into con<strong>si</strong>deration the following: 1.The application of financial management principles<br />
(shareholder’s interest and maximizing the company’s value, two-<strong>si</strong>ded transactions, comparative advantage,<br />
reasonable price, incremental benefits, risk management portfolio diver<strong>si</strong>fication, time-value of money); 2)<br />
Estimating the pos<strong>si</strong>bility of adding value ( through determining the net advantage of the merger as a difference<br />
between total market value after merger and added market values of companies before merger); 3) Estimating<br />
synergies (more efficient activities, cutting down fixed costs, complementary resources such as managerial<br />
experience and highly trained personnel; 4) Identifying and managing the risks of loo<strong>si</strong>ng such resources. The<br />
objective of this research is to underline the importance of internal audit process, as a link in nowadays’ corporate<br />
governance. The notorious accounting failures that led to the passage of the Sarbanes-Oxley Act and Securities and<br />
Exchange Commis<strong>si</strong>on (SEC) and stock exchange rulemakings have left directors, executives, their lawyers and<br />
accountants searching during the past two years to implement or improve processes and procedures which comply<br />
with the new mandates regarding disclosure, governance and accounting procedures. The final goal of this evolution<br />
is to reach a high quality level of financial reporting that is so necessary for deci<strong>si</strong>on making.<br />
Key-words: corporate governance, mergers, synergic effects, internal audit<br />

I.Introduction<br />
The choice of such a research subject took into account the growing interest of board members and executive<br />
management towards improving governance procedures, internal audit and mergers and aqui<strong>si</strong>tions.. The joint<br />
element is the corporate governance which creates internal control mechanisms and techniques aiming to make<br />
efficient deci<strong>si</strong>ons.The merging operations are par excellence corporate deci<strong>si</strong>ons of a paramount importance. The<br />
internal control and audit role has increased con<strong>si</strong>derably because of the famous accounting failures in the last few<br />
years.<br />
Adopting the Sarbannes - Oxley Law and the SEC regulations (Securities<br />
Exchange Commis<strong>si</strong>on) determined the board of directors and the executive managers to look for improving the<br />
internal audit procedures and processes and implementing some new ones according to the new norms of<br />
governance, accounting and transparency. The internal audit, due to its insurance mis<strong>si</strong>ons, but especially to those of<br />
counseling, is supposed to contribute to consolidate the corporate deci<strong>si</strong>ons and projects. A merger or an acqui<strong>si</strong>tion<br />
is a corporate mega-project involving not only a budget, but also a good deci<strong>si</strong>on’s consolidation. In this respect, a<br />
company could take over another one only if this fact heads for increa<strong>si</strong>ng the ownership’s fortune. As it could be<br />
seen in our research, this motivation is specific only to the Shareholding type governance model and not to the<br />
Stockholding type one which is more generous. This type of corporate operation presupposes the knowledge and<br />
joint application of the corporate law, fiscal and accounting knowledge. We will try to gather our knowledge to<br />
closely study these joint aspects within the large enterprises’ practice.<br />
II. The research methodology and results<br />

This documentation and research aims to highlight the internal audit’s importance as a ba<strong>si</strong>c bangle in the present<br />
corporate governance. The objectives of this research are to put into practice the internal audit’s work principles and<br />
financial management within the merging transactions. The used methods are putting the principles into practice<br />
through evaluation techniques and comparative analy<strong>si</strong>s. The research result will describe the potential impact of<br />
such merging transactions upon the ownership’s fortune. It will also depict the internal audit role in consolidating<br />
and evaluating post factum the mergers. Suppo<strong>si</strong>ng that the merging operations are just a false pretense, the internal<br />
audit procedures will be a useful instrument in this field. In conclu<strong>si</strong>on, we would like to present the research result<br />
as an extra argument for organizing and consolidating the internal audit’s po<strong>si</strong>tion within the Romanian corporations.<br />
2.1. Structures, mechanisms, models and actual trends within the corporate governance (enterprise)<br />
The recent worldwide economy has evolved around USA where the corporate governance is a national phenomenon<br />
which has become international through globalization. After the great financial failures in the early 2000’s, (frauds,<br />
from all points of view!), people start talking a lot about the corporate governance and the internal control<br />
mechanisms as systems meant to protect the financial <strong>si</strong>tuations’ credibility through financial informing/reporting<br />
mechanisms which are supposed to be as well controlled as pos<strong>si</strong>ble. In this respect, in Romania, the technology and<br />
even the related mechanisms have been already “imported”, although the content is not entirely unknown. But what<br />
is the corporate or enterprise governance? What are the present trends, models, mechanisms and structures? This<br />
difficult question has a fully convincing and at the same time, academic answer as Univ. Prof. PhD. N. Feleagă has<br />
proved in a series of articles published in CECCAR magazine in 2008 - Accounting, expertise and bu<strong>si</strong>ness audit.<br />
The enterprise governance covers the set of disposals ensuring that the objectives followed by the managers are<br />
legitimate and the working means are adapted to reach these objectives as Feleagă points out (2007, pg.13). The<br />
theoretical bases of the enterprise governance are as follows: (1) the property rights’ theory (usus - the right of u<strong>si</strong>ng<br />
an asset, fructus- the right of collecting "the fruit" of the asset, and abusus – the right of selling an asset); (2) the<br />
agency theory in which the enterprise is a node of contracts binding the investors and managers as Jensen and<br />
Meckling (1976) quoted by Feleagă (2007, pg.15) proved. Within the Romanian law, the relation refers to the<br />
juridical mandate relations between the ownership (general meeting) and the enterprise managers (board of directors)<br />
which in its turn could delegate the managers’ skills. The key-element of this theory having a complete practical<br />
application in the companies is lining up the management interest to the investors’ interest which has always been<br />
the enterprise maximized value (in fact, equity - shareholder’s fortune). The internal mechanisms of lining up the<br />
managers to the shareholder’s interest are as follows: the shareholders’ right to vote, the control imposed by the<br />
board of directors, the ways to stimulate and remunerate managers. The external mechanisms of lining up the<br />
managers to the equity owner’s interest are as follows: the financial market, the directors/managers labor market, the<br />
competition on the goods and service market. The agency relation (mandate) between the investors and managers<br />
implies a deci<strong>si</strong>on-based delegation task (it presupposes agency costs –managers’ remuneration) and as a result some<br />
inevitable conflicts appear between the parties. The conflict solving is based on three devices and structures: (1) the<br />
financial politics (the politics of distributing dividends, the debt recourse, free cash flow issue), (2) External control<br />
systems (various markets and external audit), (3) Internal control systems (internal control organized by executive<br />
managers and internal audit organized by the board of directors to evaluate the internal control made by the<br />
executive managers). The models of corporate governance used in Europe are: (1) the shareholder type model<br />
used in Anglo-Saxons countries and USA where the financial markets are very well developed, and the major<br />
objective to reach by the enterprise is to maximize the value in the shareholders’ advantage (profit and stock<br />
exchange), (2) the stakeholder type model presented in Japan and most of the European countries (out of which<br />
France and Germany are separated) where the financial markets are not very well developed, and the major objective<br />
to reach by the enterprise is less to maximize the value in the shareholders’ advantage but to defend the interest of all<br />
the parties involved (employees, bu<strong>si</strong>ness partners, banks, shareholders, managers etc). The image of the enterprise<br />
governance system could be proved by grouping its components in structures, procedures and behaviors. The<br />
structures are as follows: internal- General Meeting of Shareholders, Board of Directors and external - regulating<br />
authorities. We mention that the internal audit is a structure placed between General Meeting of Shareholders-<br />
Board of Directors and the executive management. The procedures are explained in corporate governance,<br />
accounting and commercial codes and laws. The behavior is specific to the agents (managers, executive directors)<br />
respon<strong>si</strong>ble for administering the shareholders’ fortune. These components’ hierarchy makes us conclude that the<br />
corporate governance is the management of management, as Perez (2003), quoted by Feleagă (2008) empha<strong>si</strong>zes.<br />
As far as the internal audit’s role is concerned, we can say that it expresses the management quality as long as it<br />
constantly evaluates the management and internal control processes belonging to the executive management. In<br />
terms of the activity pursuing principle, the trust in delivering the counterpart is vital, but this trust is based, from the<br />
formal point of view, on both the internal reports and the external financial communication (N. Feleagă, L. Feleagă,<br />
2008). Here, the preoccupations of this paper’s authors are met: on the level of the financial reports, they represent<br />
72
a source of documentation for those interested in major transactions (mergers and acqui<strong>si</strong>tions) and a contribution to<br />
the published financial data credibility for those interested in internal control systems (internal audit). The actual<br />
public viewpoint related to the ownership’s role within the corporate governance shows that the institutional<br />
investors play a <strong>si</strong>gnificant role (especially in the capital market) and the institutional or individual shareholders’<br />
general attitude needs to be proactive. It means that they are supposed to vote efficiently in the General Meeting of<br />
Shareholders and not to sell their assets when the enterprise goes through a difficult period. The present trend within<br />
the enterprise governance is the shareholders’ active behavior (N. Feleagă, 2008) which needs to be more and more<br />
encouraged taking into account the actual financial cri<strong>si</strong>s’ effects.<br />

acquiree becomes blurred because shares of each of the consolidating companies are exchanged for shares of the new<br />
company. Both of the consolidating companies lose their independent existence, often becoming sub<strong>si</strong>diaries of the<br />
new company or, in combination, becoming the new company. These tranzactions are always bilateral because<br />
aquiring a company implies in most cases paying a merger prime, above market value of the company aquired,<br />
substantial enough to convince the aquiree’ shareholders to sell their own stock. Acqui<strong>si</strong>tions attract headlines<br />
because of the drama of the battle of control. Its well known the case when the front page of the<br />

carried an article headlined “Bidding War: Offers for RJR Pit KKL and Shearson in a Battle for Turf”, which<br />
announced the bid of Kohlberg Kravis Roberts & Company (KKR) for control of RJR Nabisco. Five days earlier, a<br />
management-led group had announced its intention to develop a proposal, in conjunction with Shearson Lehman<br />
Hutton, to acquire RJR Nabisco in a leveraged by out valued at $75 per common share. A leveraged by out is an<br />
acqui<strong>si</strong>tion that is financed mainly, sometimes more than 90%, by borrowing. The KKR bid amounted to $90 per<br />
share. The battle for control unfolded over the ensuing <strong>si</strong>x-week period. It involved three bidding groups, no fewer<br />
then ten of the leading investment banks, and a veritable army of lawyers, information agents, accountants and<br />
commercial banks. KKR finally prevailed when it offered to pay $109 per common share, 45% more than the<br />
management-led group’s original proposal and a staggering aggregate bid of $25 billion. (Douglas R. Emery, John<br />
D. Finnerty, John D. Stowe, 1998 p. 726). In this paper, we’ll show how to analyze corporate<br />

Look for opportunities to make profitable acqui<strong>si</strong>tions. Acquire another company only if<br />
doing so increases shareholder wealth for your company. Acquiring another company<br />
usually requires paying a premium over the prevailing market price large enough to get the acquiree’s shareholders<br />
to sell their shares. Recognize that a merger of companies that have different comparative<br />
advantages might have a po<strong>si</strong>tive net present value (NPV). Look to comparable acqui<strong>si</strong>tions<br />
for guidance regarding a reasonable price to pay for an acqui<strong>si</strong>tions. Look for opportunities to<br />
rede<strong>si</strong>gn securities or structure of an acqui<strong>si</strong>tions transactions to enhance value. Calculate the<br />

Specific Financial Techniques - A corporate acqui<strong>si</strong>tion is usually a substantial capital investment for the �¤�©§�¤��£���£�¤, acquiring company. According to Emery, Finnerty and Stowe (1998, p. 726), 1996 was a boom period in this field.<br />
an acqui<strong>si</strong>tion can have a great impact on shareholder wealth than other of capital investment.<br />
The analytical tools and ba<strong>si</strong>c deci<strong>si</strong>on rules of capital budgeting still apply. However, particular care must be taken<br />
in applying these tools because of the enormous <strong>si</strong>ze and complexity of the investment.<br />
In Romania, the law reform in finance and economics fields through the articles 233 to 245 in the Company<br />
Law (in force), through the Ministry of Finance Order 1223/1998 (abolished),Ministry of Finance Order 1078/2003<br />
(abolished) and Ministry of Finance Order 1376/2004 (in force) regarding the mergers, splits and winding up of<br />
companies only refers to merger with winding up the absorbed company and consolidation with the winding up of<br />
the combining companies in order to form a new company. Consequently, the national laws lead to the use of<br />
mergers for reorganizing the equity, not for the external development of companies through mergers and<br />
acqui<strong>si</strong>tions. This is the difference between mergers with winding up of the<br />
�£�¤<br />
in Romania, and mergers with<br />
turning the into<br />

it’s<br />
winding up but can mean only lo<strong>si</strong>ng the right to take bu<strong>si</strong>ness deci<strong>si</strong>ons, which are taken at corporate level. A<br />
merger involves the acqui<strong>si</strong>tion of an entire company. Buying a company, with its own portfolio of assets and its<br />
liabilities, is more complicated than buying a new machine or building a new plant. In addition, complex tax issued<br />
must often be resolved. For these reasons, estimating the incremental cash flows is inherently more difficult than the<br />
measurement problems encountered in capital budgeting project. Also, how a company finances an acqui<strong>si</strong>tion takes<br />
on added importance. The economics of the investment and how the company finances its tend to interact because,<br />
the acqui<strong>si</strong>tion can alter the acquirer’s (acquiror’s) financial structure. Thus, estimating the required return is also<br />
inherently more difficult in the case of corporate acqui<strong>si</strong>tions than in other forms of capital investment. Yet accuracy<br />
is often crucial because of the amount of corporate funds that the acquirer must commit to the transaction.<br />
The shareholders of an acquiring company can benefit from a merger only if the two companies are worth more in<br />
combination than separately. To provide a framework for discus<strong>si</strong>on, suppose that acquirer and acquiree are worth<br />
Va and Vb in total market value (that is, the total market value of their assets), respectively. They would be worth<br />
Vab in total market value in combination. The acquirer must normally offer the acquiree’s shareholders some<br />
premium, Pb above Vb to induce them to sell their shares. The acquirer also incurs various costs and expenses (E).<br />
The net advantage to merging (NAM) to the acquirer’s shareholders equals the difference between:<br />
1. the total market value of the company post-merger net of the cost of completing the transaction and<br />
2. the total market value of the companies before the merger<br />

�¤¢�£��£�¤��¤��<br />
NAM=Vab-(Vb+Pb)- E- Va= [ Vab-(Va+Vb)]-Pb-E<br />
If the net advantage to merging is po<strong>si</strong>tive, the merger would increase the wealth of the acquirer’s<br />
shareholders. The term in brackets in equation represents what is commonly referred to as the a<br />
merger. The whole is worth more than the sum of the parts when this expres<strong>si</strong>on is po<strong>si</strong>tive. Under de Principle of<br />
Two-Sided Transactions, the premium Pb represents both a gain to the acquiree’s shareholders and a cost to the<br />
acquirer’s shareholders. Even if the synergistic effect is po<strong>si</strong>tive, the acquirer’s shareholders will benefit only if the<br />
premium Pb and the expenses are less than the synergistic benefits. One of the more interesting issues in the area of<br />
mergers and acqui<strong>si</strong>tions is the <strong>si</strong>ze of Pb in relations to Vab-(Va+Vb). If Pb is large enough, NAM can be negative.<br />
In that case, the acquirer will have “overpaid” for the acqui<strong>si</strong>tion. Example:Company A, with a total market value of<br />
$5 million, is planning to acquire Company B, which has a total market value of $1.5 million. Company A estimates<br />
that the merged company will be worth $7.5 million as a result of operating and other efficiencies. Company’s<br />
investments bankers have advised that company A will have to pay a $0.6 million premium in price to acquire<br />
company B. Merger-related costs and expenses will amount to $0.1 million. Applying equation we find that net<br />
advantage to merging is:<br />
�<br />
NAM=[7.5-(5.0+1.5)]-0.6-0.1=$0.3 million<br />
Synergy creates $1 million of value (=7.5-[5.0+1.5]). Of this amount, $0.6 million is paid to company B’s<br />
shareholders, and $0.1 million covers transaction-related expenses. Company A’s shareholders wind up a net<br />
increase in their wealth of $0.3 million. Thus the merger would benefit both companies’ shareholders.<br />
Evidence suggests that mergers do tend to produce synergy, at least when the two companies are in the same<br />
industry, and the shareholders of acquired companies tend to benefit handsomely. Target stockholders generally<br />
receive takeover premiums averaging between 30% and 50% for their shares. In contrast, the shareholders of<br />
74
acquiring companies tend to realize only very modest gains. This sharing of benefits is probably due to capital<br />
market efficiency, reflecting the impact (actual or potential) of competing acquirers. The Romanian experience and<br />
framework show that mergers and aqui<strong>si</strong>tions (that can also take place after split ups) can generate the so-called<br />
capital primes.This is an additional capital and is the po<strong>si</strong>tive difference between book value of shares issued during<br />
merger and their nominal value (merger primes). In the case of aquiring through split-up or divi<strong>si</strong>on the difference<br />
between the fair value of assets contributed by shareholders and the nominal value of shares is called contribution or<br />
subscription prime. A merger can be economically beneficial only if the sum of parts exceeds the whole. There is at<br />
least one <strong>si</strong>tuation in which this can happen: ©��£¤�¤��¤¢©�£��¤��£�£¤��£¤�©��¤�����£¤�����©¨¤.<br />
Two companies may decide to merge in order to achieve ��¤¢©�£��¤��£�£¤��£¤�or to take advantage of<br />
The merged companies can eliminate duplicate facilities, operations, or departments (the<br />
financial staff of the acquiree is usually one of the first redundancies to be eliminated). Con<strong>si</strong>der two airlines with<br />
overlapping routes. By merging their operations, they can better coordinate scheduling and eliminate excess capacity.<br />
Achieving operating efficiencies is more likely to result from horizontal or vertical merger than from a conglomerate<br />
merger. A combines two companies in the same line of bu<strong>si</strong>ness. A involves<br />
integrating forward toward the consumer, or back-ward toward the source supply, in a particular line of bu<strong>si</strong>ness.<br />
The merger of two airlines is a horizontal merger. When a company purchase one of its parts suppliers, that is a<br />
vertical merger. Most mergers in the United States <strong>si</strong>nce World War II have been of the conglomerate type.<br />
One means<br />
¢¤��§¢�¤�(management<br />
of achieving operating efficiencies involves combining two companies that have the<br />
expertise, strong sale staff, skilled product engineering staff). But a merger<br />
will be beneficial to both only if it enables each company to obtain what it needs more cheaply than it could have if it<br />
had remained on its own.<br />
Two companies in the same line of bu<strong>si</strong>ness might also merge in order to achieve in<br />
production, distribution,<br />
¤�����£¤�����©¨¤�<br />
or some other phase of their operation. Economies of scale occur when the average unit cost<br />
of goods sold decreases as output expands. For example, a higher volume of production might permit a company to<br />
build larger, more efficient plants than the smaller ones it must build now. Achieving economies of scale in<br />
production is the key motive underlying most horizontal mergers.<br />
Operating efficiencies and economies of scale are the main sources of any synergy. A conglomerate merger<br />
has the least potential for generating them. In any case, one must be careful in asses<strong>si</strong>ng potential operating<br />
efficiencies and potential economies of scale. They may never be realized. For example, merging an insurance broker<br />
and a securities broker to achieve economies of distribution may fail to yield the anticipated benefits if the brokers<br />
cannot (or <strong>si</strong>mply will not) sell each other’s products.<br />

2.3 The internal audit and its po<strong>si</strong>tion in enterprises<br />
According to the definition given by the Internal Auditors Institute (the global body in this field having its<br />
headquarters in SUA, Florida state), the internal audit is an objective and independent activity of insurance and<br />
counseling/ guidance referring to the control level on operations as it guides enterprises in order to improve<br />
its operations and contributes to create added-value. The corporations whose annual financial <strong>si</strong>tuations are<br />
subject to the financial audit, according to the law or the shareholders’ option, organize the activity of internal<br />
audit within a separate department belonging to the organizational structure. Optionally, this activity can be<br />
externalized on a contractual ba<strong>si</strong>s. The main characteristics of this activity are:<br />
1)It is an objective and independent activity providing an insurance to the entity that it benefits by a control<br />
level on the operations and that means the following: a mental attitude of independence and not necessarily a<br />
surveillance of those who make mistakes, a participative approach and not a post factum correction of the operations,<br />
a constructive approach of the dysfunctions and not a confrontation with those respon<strong>si</strong>ble for the mental attitude of<br />
independence, it depends on the competence and not on the po<strong>si</strong>tion within the entity. The internal audit is an<br />
objective and independent activity of insurance and counseling and that means that it is supposed to measure not<br />
only the <strong>si</strong>ze of the deficiencies, but also to suggest how these could be corrected and prevented. The top priority is<br />
to de<strong>si</strong>gn and put into practice an internal control system;<br />
2)It guides the entity to improve its operations and contributes to add an extra value namely it helps the<br />
entity to reach its objectives by evaluating the processes of risk management, control and governance through a<br />
systematical and methodical approach and making propo<strong>si</strong>tions to consolidate their efficacy. Improving the activity<br />
takes into account the internal audit preoccupation to come into line with the operations in order to protect the<br />
entity’s assets and to increase their efficacy and efficiency. The internal audit HELPS, ASSISTS, COUNCEL<strong>IN</strong>G,<br />
but does not replace the management respon<strong>si</strong>bility. Its principle is to pass from the post factum criticism to the<br />
construction of a new organizational culture.<br />
75
3)The insurance services aim to evaluate the proofs to provide an independent opinion or conclu<strong>si</strong>on related to a<br />
process, a system or other subjects. The insurance represents the objective assessment of the proof in order to<br />
provide an independent assessment or opinion on risk management, internal control or governance/managing<br />
processes. The internal audit provides the entity with the insurance that it has a control level on the operations.<br />
The insurance services improve the DECISIONS’ QUALITY by improving the <strong>IN</strong>FORMATION QUALITY AND<br />
AVAILABILITY;<br />
4) The counseling services (it appears the term of counseling in the public internal audit in our country) are formal<br />
recommendations generally given at a client’s specific mis<strong>si</strong>on request. The counseling stands for internal audit<br />
services except for the insurance services of the internal audit by which the management is as<strong>si</strong>sted<br />
(guided/counseled) to reach its objectives. The counseling’s applying area and nature are established together with<br />
the client.<br />
5) The internal audit helps the organization to reach its objectives due to a systematical and methodical<br />
approach (the profes<strong>si</strong>onal method makes the whole difference), to evaluate and improve (we can improve even<br />
what is already satisfactory), the processes of risk management (if it is well managed, a risk is no longer seen as a<br />
danger which must be immediately eliminated, but as a financial, commercial, organizational and technical<br />
opportunity etc.). What is the internal auditor’s role? He identifies and evaluate the organization’s risks in order to<br />
establish the control level/ degree and take the necessary measures), the control processes (the internal audit<br />
evaluates the internal control system taking into account its efficiency and adequacy to the organization’s objectives-<br />
the internal control models: COSO, COCO, CADBURY-TURNBULL, K<strong>IN</strong>G,VIENOT), corporate governance<br />
processes (the internal audit as<strong>si</strong>sts the board of directors and evaluates the corporate governance from the<br />
efficiency, efficacy, transparency and integrity point of view – the internal control is the corporate governance’s base<br />
as it a matter of transparency. From the above mentioned remarks it derives that the internal audit is entitled to<br />
evaluate the QUALITY OF MANAGEMENT carried out by the executive managers.<br />
2.4 Pos<strong>si</strong>ble internal audit mis<strong>si</strong>ons and procedures before and after the merger in a Romanian<br />
enterprise<br />
The mergers and acqui<strong>si</strong>tions represent a dynamical process of strategy and corporate-organizational culture.<br />
The empirical evidence shows a high rate in failures in creating an extra value for the shareholders as a result of<br />
these transactions. In this respect, the corporate internal audit has changed its traditional role based on subsequent<br />
control and taken over a guidance/counseling role based on risk analy<strong>si</strong>s.<br />
The internal audit can contribute to the consolidation of some correct deci<strong>si</strong>ons referring to the merger. It can also<br />
interfere in some other different stages of it. Moreover, the internal auditors will be able to evaluate the operation’s<br />
success or failure through subsequent procedures and mis<strong>si</strong>ons. We con<strong>si</strong>der worth studying the internal audit<br />
pos<strong>si</strong>ble po<strong>si</strong>tion in a Romanian enterprise involved in a merging transaction. In Romania, the merger is defined by<br />
the Corporation Law as an operation in which two or more corporations decide separately to transfer assets or<br />
liabilities to one of these corporations or to establish a new one to carry out a joint activity. The divi<strong>si</strong>on takes place<br />
by the complete sharing of the assets and liabilities of one corporation cea<strong>si</strong>ng its existence, between two or more<br />
existing corporations (to which the operation is an acqui<strong>si</strong>tion) or which comes into existence in this way. By<br />
merging and divi<strong>si</strong>on there is an exchange of notes (assets) between the participating enterprises. The exchange ratio<br />
can be calculated within the procedures of establishing the economic output of the enterprises prone to merge. The<br />
share’s absolute value is less important than their "economic weight" as Malciu (2000, p. 63) underlines. As a result<br />
the evaluation of the merger intake is inferior to the shares’ exchange parity. The merger prime is calculated as the<br />
difference between the book net value of the latest shares and there nominal cost. There is a tight competition in<br />
which not only the share’s absolute value matters but also its value in comparison with other shares and especially<br />
with the net asset of the absorbing enterprise. The merger’s prime expresses a bigger output of the absorbing<br />
enterprise given by a value of the share which is bigger than the absorbed enterprise’s shares. The merging or<br />
devi<strong>si</strong>ng date represents the exact date when the assets or liabilities are transferred and registered in the commerce<br />
registry. This date when the enterprise’s assets and debts are effectively transferred, from the juridical point of view,<br />
marks the property transfer, and this fact is also mentioned in the commerce registry. The more numerous and<br />
complicated<br />
these adjustments are, the longer the period from "the accounting reference date" to the date of merging or effective<br />
divi<strong>si</strong>on. As Dobre (2005, p. 186) points out, practice unfortunately proves the lack of understanding of the<br />
difference between the accounting reference date and the operation date by the real delivery of the patrimonial<br />
76
elements. 2 The accounting procedures and stages regulated in Romania meant to be followed during the merger by<br />
absorption are: 1. approving by General Meeting of Shareholders the merging operations. 2. Inventorying and<br />
evaluating the assets and liabilities of the corporations prone to merge. 3. Drawing up financial <strong>si</strong>tuations by all the<br />
enterprises involved in the merger. 4. Establishing the private equity (the net asset) on the ba<strong>si</strong>s of each involved<br />
enterprise’ merging balance sheet. 5. Establishing the asset exchange ratio. 6. Establishing the exchange parity of the<br />
assets or social parties. 7. Elaboration of the merging project which will be published by the absorbing.<br />
From the internal audit and evaluation of the management’s quality point of view, in case of a merger<br />
transaction, in the following table we shall present the coherence between the way and the moment in which the<br />
internal auditors interfer in the assessment of the deci<strong>si</strong>on, in progres<strong>si</strong>ng with the stages of the transaction and in<br />

Preventing publication of the merger draft due to<br />
the difference between accounting reference date<br />
and effective date of the merger as the date of<br />
transmis<strong>si</strong>on of property items.<br />
There are several criteria for valuation such as<br />
book adjusted net asset value, value of yield,<br />
forecasted results, exchange value, but the<br />
provided adjustments should be recorded in the<br />
accounts before preparing the merger balance<br />
sheet.<br />
The exchange ratio may be the result of<br />
negotiations between the parties or only a<br />
mathematical calculation based on the financial<br />
statements. However, the starting point is the<br />

to be reasonable to the <strong>si</strong>ze of the companies<br />
involved, the stakes envisaged or the parallel<br />

Internal auditors’ work in all 3 stages (phases) of operation: (1) background of the deci<strong>si</strong>ons, (2) the progress of steps and<br />
procedures for the merger, (3) monitoring the effects of synergy and added value estimate, includes procedures and specific<br />
activities, presented in the following summary:<br />
The procedure for collecting and proces<strong>si</strong>ng<br />
information<br />
Purpose: collection of information regarding the<br />
audited structure / activity so that the auditor should be<br />
familiar with the area to be audited and identify<br />
successful factors for the audit mis<strong>si</strong>on.<br />
Objective: the premise of the procedure is the divi<strong>si</strong>on<br />
of audited processes or activities in elementary tasks,<br />
identifying the risks of each burden and evaluating<br />
them.<br />
The procedure for collecting information involves:<br />
Identifying the main elements of the economic<br />
context in which the audited entity or activity<br />
operates;<br />
Knowledge of the legislative and regulatory<br />
framework in governing the bu<strong>si</strong>ness of the<br />
audited entity or activity.<br />
Identification of control systems for a prior<br />
assessment of the strengths and weaknesses;<br />
Taking into account <strong>si</strong>gnificant findings and<br />
recommendations of the permanent file and<br />
previous internal audit reports, relevant for<br />
setting objectives for the internal audit<br />
mis<strong>si</strong>on;<br />
Identifying and evaluating <strong>si</strong>gnificant risks;<br />
Identifying potential sources of information<br />
that could be used as audit evidence.<br />
Internal auditors evolve specific activities:<br />
1. Identify laws, regulations and rules applicable<br />
to the audited structure/ activity;<br />
2. Appreciate the factors of success for the<br />
audited mis<strong>si</strong>on;<br />
3. Obtain for analy<strong>si</strong>s: organization chart,<br />
operational regulations, job descriptions,<br />
written proceedings of the audited structure or<br />
activity;<br />
4. Identifies the respon<strong>si</strong>bilities of the<br />
employees;<br />
5. Studying the flow of the information within<br />
the audited structure;<br />
6. Perform analytical procedures on the<br />
performance of the audited structure or<br />
activity with a view to analy<strong>si</strong>s the risks and<br />
quality of management (if it is one of the<br />
objectives).<br />
The procedure for identification and analyzing of risks<br />
Purpose: identify specific structure or audited area risks and<br />
evaluating the audited activity’s internal control.<br />
Objective: the risk assessment is based on: the nature and<br />
specific of the audited function or activity, the quality of internal<br />
control, the gravity of direct or indirect consequences of the<br />
risks, the risk probability.<br />
Internal auditors evolve specific activities:<br />
1. Achieving based on the information collected the<br />
auditory list of activities;<br />
2. For each audited activity are established ba<strong>si</strong>c tasks;<br />
3. Identify risks for each elementary task;<br />
4. Specify criteria for risk assessment;<br />
5. Assess the identified risks;<br />
6. Setting the audited objectives as a result of the risks<br />
identified;<br />
7. Specify the specific devices of each task (objectives,<br />
means, information systems);<br />
8. Elaborate the Risk Analy<strong>si</strong>s Panel.<br />
The Risk Analy<strong>si</strong>s Panel contain:<br />

III. Research-based conclu<strong>si</strong>ons and profes<strong>si</strong>onal and legal arguments meant to consolidate the internal<br />
audit’s po<strong>si</strong>tion within the Romanian corporations<br />
The performance of the acqui<strong>si</strong>tion and merging processes is not an accident. It is based on financial management<br />
principles, generating added-value judgments, arguments related to advantages and economic synergies. These can<br />
be con<strong>si</strong>dered when making merging deci<strong>si</strong>ons through internal controls and internal audit’s evaluations. The internal<br />
audit mis<strong>si</strong>ons carried out before and after the mergers take into account: Applying financial management principles<br />
(shareholders’ interest and maximizing the company’s value, bilateral transactions, the comparative advantage, an<br />
affordable price, increa<strong>si</strong>ng the company’s value, the added benefits, handling the risks and diver<strong>si</strong>fying the<br />
participants, and money time-value terms); Estimating the pos<strong>si</strong>bilities of generating an added-value (by calculating<br />
the merger’s net advantage as a difference between the company’s total market value after the merger and the two<br />
companies’ total market value before the merger); Asses<strong>si</strong>ng the economic advantages and the company’s synergies<br />
after the merger (more productive exploitations, savings on the fixed costs, complementary resources such as<br />
managing experience, highly qualified technical staff); Identifying the risks of lowering or lo<strong>si</strong>ng these economic<br />
output resources. The making of acqui<strong>si</strong>tion and merging deci<strong>si</strong>ons are based on the financial <strong>si</strong>tuations’ credibility.<br />
The corporations’ experience in our country could be also developed more and more due to profes<strong>si</strong>onal accountants<br />
and internal auditors. Although it has been recently regulated, the corporate (private) internal audit is not well<br />
organized in all the enterprises. In this respect the arguments are legal and profes<strong>si</strong>onal: Legal arguments:<br />
provi<strong>si</strong>ons of Art. 160, alin.(2) in Corporation Law no. 31/1990, modified and completed by Law no. 441/2006 3 ;<br />
Profes<strong>si</strong>onal arguments: the Internal Audit International Standards are available on the <strong>si</strong>te belonging to USA<br />
Florida Internal Auditors Institute (www.theia.org), and to Romanian Internal Auditors Association (RIAA- branch<br />
IIA-SUA www. aair. ro) and through the National Norms on the internal audit issued by CAFR and available on<br />
CAFR’s <strong>si</strong>te (www.cafr.ro). The standards’ objectives are: to delimitate the ba<strong>si</strong>c principles representing the<br />
internal audit practice, to provide a proper framework for realizing and promoting a wide range of activities meant to<br />
add an extra value through quality and quantity, to establish the evaluation background for the internal audit<br />
performance, to improve the organizational operations and processes (referring to the organization’s total quality).<br />
The internal audit’s profes<strong>si</strong>onal standards are: Attribute Standards – applying to all internal audit services;<br />
Performance Standards - applying to all internal audit services; Implementation Standards- applying to the<br />
specific types of mis<strong>si</strong>ons: insurance and counseling, and is applied together with the other standards. Taking into<br />
account the present economic and liquidity cri<strong>si</strong>s, the corporate internal control system’s role in which the internal<br />
audit is an integrant part has substantially increased due to the famous accounting failures in the last years. After<br />
adopting the Sarbannes-Oxley Law and SEC (Securities Exchange Comis<strong>si</strong>on) provi<strong>si</strong>ons, the boards of directors<br />
and executive managers have constantly aimed at improving the internal audit procedures and processes and<br />
implementing new ones according to the new norms of governance, accounting and transparency. These<br />
normalization evolutions’ final goal is to reach a high quality level of financial reporting as it is of paramount<br />
importance within the deci<strong>si</strong>on making process, including the acqui<strong>si</strong>tion and merging field.<br />
This article is a result of the project „Doctoral Program and PhD Students in the education research and<br />
innovation triangle”. This project is co funded by European Social Fund through The Sectorial Operational<br />

<strong>IN</strong>TRODUCTION<br />
This paper investigates the regulatory transformations that have shaped the sustainability<br />
disclosure starting with the emergence of sustainability development concept until present.<br />
One of the most quoted definitions of sustainable development is that proposed by the<br />
World Commis<strong>si</strong>on on Environment and Development (WCED) chaired by Gro Harlem<br />
Brundtland, prime minister of Norway in 1987. According to the Brutland Report ("Our common<br />
future") sustainable development means "to ensure that development meets the needs of the<br />
present without compromi<strong>si</strong>ng the ability of future generations to meet their own needs”. The<br />
commis<strong>si</strong>on was created to address growing concern "about the accelerating deterioration of the<br />
human environment and natural resources and the consequences of that deterioration for<br />
economic and social development." United Nations (UN) convened WCED in 1983. In<br />
establishing the commis<strong>si</strong>on, the UN General Assembly recognized that environmental problems<br />
were global in nature and determined that it was in the common interest of all nations to establish<br />
policies for sustainable development.<br />

The sustainable development is the way in which the developing and in full process of<br />
industrialisation countries will avoid to become as the present industrialised countries based on<br />
intense carbon emis<strong>si</strong>ons.<br />
The three pillars of sustainable development are: economic, social and environmental<br />
development, pillars that are correlated. At the intersection of these pillars lays the sustainability<br />
concept.<br />

SUSTA<strong>IN</strong>ABLE DEVELOPMENT – A REGULATORY TIMEL<strong>IN</strong>E ¡ �¦¨�<br />
The idea of sustainability dates back more than 40 years to the new mandate adopted by<br />
The World Conservation Union (IUCN). It was a key theme of the United Nations Conference on<br />
the Human Environment in Stockholm in 1972. The concept was coined explicitly to suggest that<br />
it was pos<strong>si</strong>ble to achieve economic growth and industrialisation without environmental damage.<br />
In the ensuing decades, mainstream sustainable development thinking was progres<strong>si</strong>vely<br />
developed through the World Conservation Strategy (1980) developed by IUCN, the Brundtland<br />
Report (1987), and the national government planning and bu<strong>si</strong>ness organisations of all kinds.<br />
The Global Reporting Initiative (GRI) has pioneered the development of the world’s most<br />
widely used sustainability reporting framework and is committed to its continuous improvement<br />
and application worldwide. GRI is a large multi-stakeholder network of thousands of experts, in<br />
dozens of countries worldwide, who participate in GRI’s working groups and governance bodies,<br />
use the GRI Guidelines to report, access information in GRI-based reports, or contribute to<br />
develop the Reporting Framework in other ways – both formally and informally.<br />
The Intergovernmental Working Group of Experts on International Standards of<br />
Accounting and Reporting (ISAR) working group is hosted by the United Nations Conference on<br />
Trade and Development (UNCTAD). ISAR was created in 1982 by the United Nations Economic<br />
and Social Council (ECOSOC). [ISAR as<strong>si</strong>sts developing countries and economies in tran<strong>si</strong>tion<br />
to implement best practices in corporate transparency and accounting in order to facilitate<br />
82
investment flows and economic development. ISAR achieves this through an integrated process<br />
of research, intergovernmental consensus building, information dissemination and technical<br />
cooperation. ISAR has a number of areas of work, including: IFRS implementation, accounting<br />
by SMEs, corporate governance disclosure, corporate respon<strong>si</strong>bility reporting, and environmental<br />
reporting.<br />
THE SUSTA<strong>IN</strong>ABLE DEVELOPMENT AS GRI<br />
Sustainability reporting is the practice of measuring, and being accountable to internal and<br />
external stakeholders for organisational performance towards the goal of sustainable<br />
development. A sustainability report should provide a balanced and reasonable representation of<br />
the sustainability performance of a reporting organisation, including both po<strong>si</strong>tive and negative<br />
contributions.<br />
Sustainability reports based on the GRI Reporting Framework disclose outcomes and<br />
results that occurred within the reporting period in the context of the organization’s<br />
commitments, strategy, and management approach.<br />
Reports can be used for the following purposes, among others:<br />
o Benchmarking and asses<strong>si</strong>ng sustainability performance with respect to laws,<br />
norms, codes, performance standards, and voluntary initiatives;<br />
o Demonstrating how the organization influences and is influenced by expectations<br />
about sustainable development;<br />
o Comparing performance within an organization and between different<br />
organizations over time.<br />
All GRI Reporting Framework documents are developed u<strong>si</strong>ng a process that seeks<br />
consensus through dialogue between stakeholders from bu<strong>si</strong>ness, the investor community, labour,<br />
civil society, accounting, academia, and others. All Reporting Framework documents are subject<br />
to testing and continuous improvement.<br />
All GRI reporting documents include: The GRI Reporting Framework, The Sustainability<br />
Reporting Guidelines and some protocols that are clearing the specific and technical aspects of<br />
disclo<strong>si</strong>ng.<br />
The GRI Reporting Framework<br />
The GRI Reporting Framework is intended to serve as a generally accepted framework for<br />
reporting on an organisation’s economic, environmental, and social performance. It is de<strong>si</strong>gned<br />
for use by organisations of any <strong>si</strong>ze, sector, or location. It takes into account the practical<br />
con<strong>si</strong>derations faced by a diverse range of organisations. The GRI Reporting Framework contains<br />
general and sector-specific content that has been agreed by a wide range of stakeholders around<br />
the world.<br />
83
The Sustainability Reporting Guidelines<br />
The Sustainability Reporting Guidelines Con<strong>si</strong>sts of Principles for defining report content<br />
and ensuring the quality of reported information. It also includes Standard Disclosures made up<br />
of Performance Indicators and other technical topics in reporting.<br />
The specific and technical protocols<br />
o Indicator Protocols exist for each of the Performance Indicators contained in the<br />
Guidelines. These Protocols provide definitions, compilation guidance, and other<br />
information to as<strong>si</strong>st report preparers and to ensure con<strong>si</strong>stency in the<br />
interpretation of the Performance Indicators.<br />
o Sector Supplements complement the Guidelines with interpretations and<br />
guidance on how to apply the Guidelines in a given sector, and include sectorspecific<br />
Performance Indicators.<br />
o Technical Protocols are created to provide guidance on issues in reporting, such<br />
as setting the report boundary. They are de<strong>si</strong>gned to be used in conjunction with<br />
the Guidelines and Sector Supplements and cover issues that face most<br />
organizations during the reporting process.<br />

Reporting principles and Guidelines<br />
This section covers the area of what should be reported by an organisation, con<strong>si</strong>dering<br />
the following principles:<br />
o The materiality principle;<br />
o The stakeholder inclu<strong>si</strong>veness principle;<br />
o The sustainability context principle;<br />
o The completeness principle.<br />
The above principles must be followed by the following principles to help achieve the<br />
appropriate quality of the reported information.<br />
Standard disclosure<br />
o Principle of balance;<br />
o Principle of comparability;<br />
o Principle of accuracy;<br />
o Principle of timeliness;<br />
o Principle of reliability;<br />
o Principle of clarity.<br />
This section identifies information that is relevant and material to most organisations and<br />
of interest to most stakeholders con<strong>si</strong>dering: strategy and profile of organisation, management<br />
approach, and performance indicators.<br />
The main objective of the above principles is the accountability of the reporting<br />
organisation, aim that subscribes all the aspects of sustainable reporting.<br />
According Sustainable Reporting Guidelines issued by GRI, the accountability can be<br />
defined as: „the complete disclosure of the information regarding the aspects and indicators that<br />
reflect the organisation's impact in a way that allows to the stakeholders to make deci<strong>si</strong>ons, and<br />
all the processes, procedures and estimation made in the disclosure reporting process”.<br />
For every principle mentioned above, a definition was made, an explanation and series of<br />
tests also, in order to allow and to guide their utilisation.<br />
o Materiality principle – The information in a report should cover topics and<br />
Indicators that reflect the organization’s <strong>si</strong>gnificant economic, environmental, and<br />
social impacts, or that would substantively influence the assessments and<br />
deci<strong>si</strong>ons of stakeholders.<br />
85
o Stakeholder inclu<strong>si</strong>veness’ principle – The reporting organization should<br />
identify its stakeholders and explain in the report how it has responded to their<br />
reasonable expectations and interests.<br />
o Sustainability context principle – The report should present the organization’s<br />
performance in the wider context of sustainability.<br />
o Completeness principle – Coverage of the material topics and Indicators and<br />
definition of the report boundary should be sufficient to reflect <strong>si</strong>gnificant<br />
economic, environmental, and social impacts and enable stakeholders to assess the<br />
reporting organization’s performance in the reporting period.<br />
o Principle of balance – The report should reflect po<strong>si</strong>tive and negative aspects of<br />
the organization’s performance to enable a reasoned assessment of overall<br />
performance.<br />
o Principle of comparability – Reported information should be presented in a<br />
manner that enables stakeholders to analyze changes in the organization’s<br />
performance over time, and could support analy<strong>si</strong>s relative to other organizations.<br />
o Principle of accuracy – The reported information should be sufficiently accurate<br />
and detailed for stakeholders to assess the reporting organization’s performance.<br />
o Principle of timeliness – Reporting occurs on a regular schedule and information<br />
is available in time for stakeholders to make informed deci<strong>si</strong>ons.<br />
o Principle of clarity – Information should be made available in a manner that is<br />
understandable and acces<strong>si</strong>ble to stakeholders u<strong>si</strong>ng the report.<br />
o Principle of reliability – Information and processes used in the preparation of a<br />
report should be gathered, recorded, compiled, analyzed, and disclosed in a way<br />
that could be subject to examination and that establishes the quality and<br />
materiality of the information.<br />
Sustainable accounting<br />
In this manner there is a case to be made that sustainable accounting is an emancipatory<br />
form of accounting in that it provides both a critique of existing practices and develops<br />
alternative accounting practices.<br />
A number of questions should be raised in these conditions: „On what end or object is<br />
economical accounting focused?”, „What means do we use to seek this goals?”<br />
In seeking for an answer regarding this issue, it can be con<strong>si</strong>dered that, in a particular<br />
case, sustainable accounting is a normative product of the academics in a certain social context.<br />
In order to draw certain conclu<strong>si</strong>ons is necessary to establish the po<strong>si</strong>tion and the relationships<br />
between accounting research, accounting practice and educational function of accounting.<br />
The critiques of environmental accounting derive from two sources: critiques have<br />
emerged from a Marxist (or Marxian) perspective (Puxty, 1986), a Feminist perspective (Cooper,<br />
1992) and a deep green perspective (Maunders and Burritt, 1991). The in<strong>si</strong>ghts from each provide<br />
different lenses through which to see and judge the enabling potential of environmental<br />
accounting. In these conditions, Puxty cautions that to extend social reporting is "itself no<br />
86
challenge to the powerful... <strong>si</strong>nce it leaves the ba<strong>si</strong>c structures in place, and can even lead to their<br />
legitimisation". Under the feminist critique Cooper asserts that the "introduction of 'green<br />
accounting', however well thought out, will, under the present system of accounting do nothing to<br />
avert today's environmental cri<strong>si</strong>s”. In a <strong>si</strong>milar vein, Maunders and Burritt, employing a deep<br />
green perspective, conclude that the "light green approach [to environmental accounting] is<br />
irredeemably contaminated by its hidden (ideological) assumptions".<br />
Even the critics have doubted the ability of sustainable accounting to manage the actual<br />
environmental cri<strong>si</strong>s, GRI has de<strong>si</strong>gned a number of economic indicators that measures the<br />
sustainable performance of the reporting organisation.<br />
GRI con<strong>si</strong>ders the following clas<strong>si</strong>fication:<br />
o Economic performance<br />
o Direct economic value generated and distributed, including revenues,<br />
operating costs, employee compensation, donations and other community<br />
investments, retained earnings, and payments to capital providers and<br />
governments.<br />
o Financial implications and other risks and opportunities for the<br />
organization’s activities due to climate change.<br />

The assurance level of the sustainable reports<br />

Every reporting organisation that uses the sustainable reporting framework issued by GRI<br />
should realise an auto evaluation of their sustainable report. Organisation can choose to disclose<br />
information on three reporting levels C, B, A as they appear in GRI sustainable reporting<br />
framework. Every level reflects a certain amount of information about the reporting organisation.<br />
If the sustainable reports are checked by other external parties, the level indicator gets a „plus”<br />
(„+”) <strong>si</strong>gn, generating the following codification: C+, B+, A+.<br />
In the same time, the reporting organisation should announce GRI of the issuing of the<br />
sustainable report and provide GRI a copy of this report.<br />
CONCLUSIONS<br />
At the present moment, sustainable reporting is a relative new area and a challenge both<br />
for regulators, in order to create norms and regulations, but for practitioners, on their way for<br />
applying these methodologies. Still, the sustainable reporting normalisation has both a theoretical<br />
and practical aspect if we take into account the large multi-stakeholder network that creates the<br />
GRI organisation. In plus, we con<strong>si</strong>der the continuous process of improving for the regulations.<br />
This things being said and con<strong>si</strong>dering the critique perspective of environmental<br />
accounting, we con<strong>si</strong>der that sustainable reporting covers the area of sustainability, offering a fair<br />
image of the behaviour and the organisational impact of the sustainable development of the<br />
reporting organisation.<br />
The emerging issue in these conditions is represented by the neces<strong>si</strong>ty of auditing for the<br />
sustainable reports con<strong>si</strong>dering the fact that no standardised methodology is available for<br />
validation of the reported information. In these conditions organisations respond by generating<br />
sustainable reports issued according GRI sustainable reporting framework, according to own<br />
sustainable policies and according to other regulator bodies (e.g. Human Rights Declaration<br />
issued by United Nation).<br />

Introduction<br />
From July 2007 the world faces the most serious financial cri<strong>si</strong>s <strong>si</strong>nce the 1929 Great Depres<strong>si</strong>on. As the<br />
international financial cri<strong>si</strong>s unfolded, it was clear to all that the global financial system was in need of <strong>si</strong>gnificant<br />
reform. What has not been clear is exactly what changes are needed. In the last few months, three reports by the<br />
working group on Financial Reform have started the process to chart a way forward. These reports are led by the<br />
former Chairman of the US Federal Reserve, Mr. Paul Volcker, Lord Turner from the UK’s Financial Services<br />
Authority and the former governor of the Banque de France Mr. de Laro<strong>si</strong>ere. There is a high degree of consensus<br />

etween the three reports which is an encouraging start but one would not underestimate the difficulty of forging an<br />
international consensus across such a broad range of complicated issues. In this article I will discuss about the<br />
Laro<strong>si</strong>ere report and the recommendations it proposes to stabilize and enhance the financial system. I will focus on<br />
main recommendations: the creation of the European System for Financial Supervi<strong>si</strong>on and the review of the markto-market<br />
accounting principle. These two coordinates will reform, enhance and stabilize the financial system in the<br />
European Union. The Laro<strong>si</strong>ère Group's mandate covered the issues of how to organize the supervi<strong>si</strong>on of financial<br />
institutions and markets in the European Union, early warning and cri<strong>si</strong>s mechanisms, how to strengthen European<br />
cooperation on financial stability and how European Union supervisors should cooperate globally. The strength of<br />
the report lays in the ambitious plan to set up two main institutions of macro and microprudential supervi<strong>si</strong>on of the<br />
European financial system: the European Systemic Risk Council at macroprudential level and the European System<br />
for Financial Supervi<strong>si</strong>on at microprudential level. The Laro<strong>si</strong>ere report identifies a number of causes that triggered<br />
the present financial cri<strong>si</strong>s. The Report identifies a number of the causes of the financial cri<strong>si</strong>s such as the existence<br />
of excess liquidity, which led to ri<strong>si</strong>ng asset prices and growth in credit volume. This in turn led to a hou<strong>si</strong>ng bubble<br />
which was exacerbated by increased mortgage lending and poor lending practices. The use of structured financial<br />
products to manage such credit exposure and their lack of transparency meant that the extent of the risk being taken<br />
on by financial entities was unknown or unquantifiable. The Report also identifies a failure on the part of regulators<br />
to identify systemic issues, rather than those related to a particular firm or industry, as contributing <strong>si</strong>gnificantly to<br />
the cri<strong>si</strong>s. A failure to react to the cri<strong>si</strong>s, caused by inadequate information exchange and a marked lack of collective<br />
deci<strong>si</strong>on making between national supervisors, is also blamed for the failure to mitigate the impacts of the cri<strong>si</strong>s as it<br />
developed. As a consequence, the Laro<strong>si</strong>ere report underlines the neces<strong>si</strong>ty for the European Union to adopt<br />
measures to improve the process of systemic problems identification as well as measures to improve the exchange of<br />
information between national supervisory authorities.<br />
The creation of the European System for Financial Supervi<strong>si</strong>on<br />
The Lamfalussy process<br />
In order to understand the changes that will take place by the creation of the European System for Financial<br />
Supervi<strong>si</strong>on, it is important to present the present processes of European financial system regulation and supervi<strong>si</strong>on.<br />
The present approach to the development and adoption of financial services legislation in the European Union is the<br />
Lamfalussy process, named after the chair of the European Union advisory committee that created it, Baron<br />
Lamfalussy. It comprises a four-level procedure that speeds up the legislative process. The parts of the Lamfalussy<br />
framework which are of most direct relevance to regulators are the committees on which they are represented,<br />
notably the Committee of European Banking Supervisors (CEBS), the Committee of European Insurance and<br />
Occupational Pen<strong>si</strong>ons Supervisors (CEIOPS) and the Committee of European Securities Regulators (CESR). These<br />
are sometimes called the „Level 3 committees” because they are at level three of the four levels of the Lamfalussy<br />
process. Under the Lamfalussy arrangements, the Commis<strong>si</strong>on proposes framework legislation and it is adopted<br />
under the 'co-deci<strong>si</strong>on' procedure that involves both the European Council and the European Parliament. This is<br />
Level 1. It is supplemented at Level 2 by more detailed implementation measures, adopted by the Commis<strong>si</strong>on and<br />
endorsed by a qualified majority of Member States. The detailed Level 2 legislation is prepared by the Commis<strong>si</strong>on<br />
on the ba<strong>si</strong>s of advice provided by representatives of national supervisory authorities, acting through the 'Level 3'<br />
committees (CEBS, CEIOPS and CESR). In finali<strong>si</strong>ng their advice, the Level 3 committees consult exten<strong>si</strong>vely with<br />
providers and users of financial services. The Level 3 committees also aim to foster supervisory convergence and<br />
best practice, principally through the creation of guidance. Finally, at Level 4, the Commis<strong>si</strong>on ensures that Member<br />
States are complying with applicable legislation and it pursues enforcement action where required. Analyzing<br />
Lamfalussy process, it clearly results that, at present, the most important supervisory structures for the European<br />
financial system are the level 3 committees. The level 3 committees are examined in depth by the Laro<strong>si</strong>ere group<br />
and based on their structure, improvements in the financial supervisory system are proposed.<br />
From Lamfalussy process to a European System for Financial Supervi<strong>si</strong>on<br />
After having examined the present arrangements and in particular the cooperation within the level 3 committees, the<br />
Laro<strong>si</strong>ere group con<strong>si</strong>ders that the structure and the role of the existing committees are not sufficient to ensure<br />
91
financial stability in the European Union and all its Member States. Although the level 3 committees have<br />
contributed <strong>si</strong>gnificantly to the process of European financial integration, there are a number of inefficiencies which<br />
can no longer be dealt with within their present legal structure. This is why the Group proposes the establishment of<br />
a European System of Financial Supervi<strong>si</strong>on. The European System for Financial Supervi<strong>si</strong>on should constitute an<br />
integrated network of European financial supervisors that will work based on the level 3 committeees, improved and<br />
transformed into three European Authorities. In the Laro<strong>si</strong>ere group’s opinion, the Commis<strong>si</strong>on, the Council and the<br />
Parliament should immediately start the necessary legislative work to transform the level 3 committees into three<br />
European Authorities: a European Banking Authority, a European Insurance Authority and a European Securities<br />
Authority. The new European Authorities will replace the present level 3 committees: CEBS, CEIOPS and CESR.<br />
The European System for Financial Supervi<strong>si</strong>on will be a largely decentralised structure because existing national<br />
supervisors, who are closest to the markets and institutions they supervise, would continue to carry-out day-to-day<br />
supervi<strong>si</strong>on and preserve the majority of their present competences. But in order to be in a po<strong>si</strong>tion to effectively<br />
supervise an increa<strong>si</strong>ngly integrated and consolidated European financial market, the Authorities will carry-out a<br />
defined number of tasks that are better performed at supranational level. Particular attention will be paid to large<br />
cross-border institutions which pose systemic risks which were not detected by the present supervisory structures.<br />
The European System for Financial Supervi<strong>si</strong>on must be independent from pos<strong>si</strong>ble political and industry influences,<br />
at both European and national level. The Authorities should have sufficient resources and powers. But in order to<br />
strengthen legitimacy, proper accountability to the political authorities at the European and national levels should be<br />
ensured. In short, the European Authorities must be independent from the political authorities, but fully accountable<br />
to them. The European System for Financial Supervi<strong>si</strong>on must work with a common set of core harmonized rules and<br />
rely on high quality and con<strong>si</strong>stent information. To realise this ambitious objective, the Laro<strong>si</strong>ere group proposes a<br />
two stage process that will lead to the strengthening of the European supervisory system, will raise the stability of the<br />
financial system and will restore trust in the financial markets.<br />
Stage 1 (2009-2010): Preparing for a European System of Financial Supervi<strong>si</strong>on<br />
In the first stage, national supervisory authorities should be strengthened with a view to upgrading the quality of<br />
supervi<strong>si</strong>on in the European Union. Member States should give con<strong>si</strong>deration to the following reforms:<br />
- aligning supervisors' competences and powers on the most comprehen<strong>si</strong>ve system in the European Union,<br />
- increa<strong>si</strong>ng supervisors' remuneration,<br />
- facilitating exchanges of personnel between the private sector and supervisory authorities,<br />
- ensuring that all supervisory authorities implement a modern and attractive personnel policy.<br />
The Laro<strong>si</strong>ere group recommends that, in the process of change, the level 3 committees should:<br />
- inten<strong>si</strong>fy their efforts in the areas of training and personnel exchanges as well as work towards the creation<br />
of a strong European supervisory culture,<br />
- benefit from, under the Community budget, a <strong>si</strong>gnificant reinforcement of their resources,<br />
- upgrade the quality and impact of their mediation processes,<br />
- prepare the ground for the setting-up of supervisory colleges for all major cross-border financial firms in the<br />
European Union.<br />
The European Commis<strong>si</strong>on should carry-out, in cooperation with the level 3 committees, an analy<strong>si</strong>s of the degree of<br />
independence of all national supervisors. In this first stage, the European Commis<strong>si</strong>on should immediately begin the<br />
work to prepare legal proposals to set up the new Authorities. The European Institutions and the level 3 committees<br />
should initiate a determined effort to equip the European Union with a far more con<strong>si</strong>stent set of rules by the<br />
beginning of 2013. Key differences in national legislation stemming from exceptions, derogations, additions made at<br />
national level or ambiguities contained in current directives should be identified and removed, so a harmonized core<br />
set of standards is defined and applied throughout the European Union.<br />
Stage 2 (2011-2012): Establishing the European System of Financial Supervi<strong>si</strong>on<br />
After the preparation in Stage 1, the establishment of the European System of Financial Supervi<strong>si</strong>on is planned for<br />
Stage 2. The establishment will take place through the transformation of the level 3 committees into three new<br />
European Authorities: the European Banking Authority, the European Insurance Authority and the European<br />
Securities Authority. These Authorities should have their own autonomous budget, commensurate with their<br />
92
espon<strong>si</strong>bilities. In addition to the competences currently exercised by the level 3 committees, the newly created<br />
Authorities should have the following key-competences:<br />
- legally binding mediation between national supervisors,<br />
- adoption of binding supervisory standards,<br />
- adoption of binding technical deci<strong>si</strong>ons applicable to individual financial institutions,<br />
- coordination of colleges of supervisors,<br />
- de<strong>si</strong>gnation, where needed, of group supervisors,<br />
- licen<strong>si</strong>ng and supervi<strong>si</strong>on of specific European Union-wide institutions (like Credit Rating Agencies),<br />
- binding cooperation with the ESRC to ensure adequate macro-prudential supervi<strong>si</strong>on.<br />
In this second stage, national supervisory authorities should continue to be fully respon<strong>si</strong>ble for the day-to-day<br />
supervi<strong>si</strong>on of firms. The Group recommends that planning for the 2 stages of the new system be started<br />
immediately. To this effect, a group of high-level representatives of the Finance Ministries, the European Parliament,<br />
the Level 3 Committees, and the European Central Bank to be chaired by the European Commis<strong>si</strong>on, should come<br />
forward before the end of 2009 with a detailed implementation plan.<br />
The following diagram illustrates the future interaction between the European Systemic Risk Council at<br />
macroprudential level and the European System for Financial Supervi<strong>si</strong>on at microprudential level:<br />

The review of mark-to-market accounting principle<br />
The mark-to-market accounting principle – one of the main causes of the financial cri<strong>si</strong>s<br />
With respect to the accounting rules, the Laro<strong>si</strong>ere report underlines the importance of a wider reflection on the<br />
mark-to-market accounting principle. An in-depth analy<strong>si</strong>s of the mark-to-market accounting leads to an alarming<br />
conclu<strong>si</strong>on: mark-to-market accounting was one of the main causes that triggered and fuelled the current global<br />
fiancial cri<strong>si</strong>s. Mark-to-market accounting means that companies must value the assets on their balance sheets based<br />
on the latest market indicators of the price that those assets could be sold for immediately. The market with the<br />
greatest impact in the current financial cri<strong>si</strong>s was the hou<strong>si</strong>ng market. Excess liquidity and lax mortgage procedures<br />
led to the accelerated raise in hou<strong>si</strong>ng prices. Many firms in the financial sector had securities and complex financial<br />
94
instruments guaranteed by mortgages. But when the risks taken by these firms have emerged at the same time with<br />
the beginning of the subprime cri<strong>si</strong>s in the United States in mid 2007, hou<strong>si</strong>ng prices all over the world began to<br />
drop. Under mark-to-market accounting, declining hou<strong>si</strong>ng prices don't just reduce the value of defaulting<br />
mortgages. They reduce the value of all mortgages and all mortgage-related securities and financial instruments held<br />
by the firms in the financial sector because the hou<strong>si</strong>ng collateral protecting them is worth less. Moreover, when a<br />
company in financial distress begins fire sales of its assets to raise capital to meet regulatory requirements, the<br />
market-bottom prices it sells out for become the new standard for the valuation of all <strong>si</strong>milar securities held by other<br />
companies under mark-to-market. This prompts the beginning of a downward vicious spiral that makes more and<br />
more firms to have a balance sheet that indicates insolvency.<br />
The end result for the company is stock prices driven toward zero and bankruptcy or government takeover.<br />
The review of mark to market accounting principle – the way towards financial stability<br />
The cri<strong>si</strong>s has brought into relief the difficulty to apply the mark-to-market principle in certain market conditions as<br />
well as the strong pro-cyclical impact that this principle can have. The Laro<strong>si</strong>ere group con<strong>si</strong>ders that a wide<br />
reflection is needed on the mark-to-market principle by the accounting standard setters. Whilst in general this<br />
principle makes sense, there may be specific conditions where this principle should not apply because it can mislead<br />
investors and distort managers' policies. Long-term economic value should be central to any valuation method. The<br />
European Union deci<strong>si</strong>on from October 2008 to modify IAS-39, thereby introducing more flexibility as well as<br />
convergence with US Generally Accepted Accounting Principles, is to be appreciated. Accounting standards should<br />
be developed so that they do not bias bu<strong>si</strong>ness models, promote pro-cyclical behaviour or discourage long-term<br />
investment. The International Accounting Standards Board and other accounting standard setters should clarify and<br />
agree on a common, transparent methodology for the valuation of assets in illiquid markets where mark-to market<br />
accounting principle cannot be applied. The International Accounting Standards Board should further open its<br />
standard-setting process to the regulatory, supervisory and bu<strong>si</strong>ness communities. The over<strong>si</strong>ght and governance<br />
structure of the International Accounting Standards Board should be strengthened to face new challenges.<br />
Suggestions<br />
In order to support the successful implementation of the Laro<strong>si</strong>ere report recommendations, I shall present a few<br />
suggestions. The first suggestion is about the cross sector cooperation and communication enhancement between the<br />
three new European Authorities. Supervi<strong>si</strong>ng large complex financial institutions requires an ability to distil an<br />
enormous amount of detailed and highly technical information into a coherent picture of individual firms’ risk<br />
po<strong>si</strong>tions, to assess that picture against global market developments and to judge the viability of firms in various<br />
market scenarios. In this activity, communication plays a critical role. To avoid a pos<strong>si</strong>ble isolation tendency in the<br />
sector of which each Authority is respon<strong>si</strong>ble and in order to have a better information flow within the European<br />
System of Financial Supervi<strong>si</strong>on, I suggest the setup in parallel with the three Authorities of a Committee for Crosssector<br />
Cooperation. The Committee for Cross-sector Cooperation can have members from each Authority,<br />
de<strong>si</strong>gnated by rotation, and its main role would be to facilitate the exchange of information and best practice<br />
procedures between Authorities, as well as to centralize aspects regarding microprudential supervi<strong>si</strong>on within the<br />
European System of Financial Supervi<strong>si</strong>on.<br />
The second suggestion refers to the neces<strong>si</strong>ty to have a fiscal power, along<strong>si</strong>de the supervisory power, within the<br />
European System of Financial Supervi<strong>si</strong>on. Any structure for financial supervi<strong>si</strong>on and stability needs a fiscal backup.<br />
Although this aspect has been ommitted by the Laro<strong>si</strong>ere report, the financial cri<strong>si</strong>s has made that abundantly<br />
clear. The current national structures are backed by the national Treasuries. A European financial supervisory<br />
structure needs a European fiscal arrangement at institutional level. Without such a European fiscal arrangement,<br />
cri<strong>si</strong>s management has to remain at national levels, leading to financial protectionism. Moreover, leaving expen<strong>si</strong>ve<br />
cri<strong>si</strong>s management at national level, while shifting supervisory powers towards the supra-national level, could be<br />
described as national taxation without proper control and national representation. Afiscal power would strengthen the<br />
authority and efficiency of the European System of Financial Supervi<strong>si</strong>on in times of economic effervescence but<br />
especially in times of cri<strong>si</strong>s.<br />
The third suggestion refers to the differentiated application of the mark-to-market accounting principle on classes of<br />
assets and liabilities. Because the mark-to-market accounting principle can be applied in stable economic conditions<br />
but not in a cri<strong>si</strong>s due to its pro-cyclical effect, its differentiated application could eliminate the inconvenient. More<br />
95
precisely, the application of the mark-to-market accounting principle could be done only for those asset classes for<br />
which the market is not in cri<strong>si</strong>s or the activities in that market are not turbulent. In this way, the distortions that the<br />
mark-to-market accounting principle creates when applied in cri<strong>si</strong>s <strong>si</strong>tuations could be avoided and the firms’<br />
balance sheet strengthened.<br />
Conclu<strong>si</strong>ons<br />
The aspect of the supervisory changes for the financial system in the European Union presented in the Laro<strong>si</strong>ere<br />
report is conceptually clear and with sufficient implementation details. Overall, its general structure is attractive. It<br />
makes it clear that the key is to coordinate not to centralise all activities in one institution. The review of the mark-tomarket<br />
accounting principle is necessary for a better evaluation of the firms’ assets as well as to avoid the systemic<br />
risks generated by pro-cyclicality. Along<strong>si</strong>de the review of the mark-to-market accounting principle, the creation of<br />
the European System of Financial Supervi<strong>si</strong>on are the two main directions towards financial stability in the European<br />
Union. The change of the present financial supervisory structures by its transformation into an institution with<br />
<strong>si</strong>gnificant powers and resources is a definitive step towards a systemic approach to financial markets’ regulation and<br />
supervi<strong>si</strong>on at the European Union level. Risks will be better detected and managed. The stability of the financial<br />
system in the European Union will depend on these changes.<br />

REVIEW OF THE SPECIALTY LITERATURE<br />
Accounting is a technique, or in its contemporary dynamics, a techno science where permanently developed. The<br />
method of double games is a ba<strong>si</strong>c method of the accounting technique, and it has its origins still in the Middle Ages.<br />
However, about the double game approved in the year 1340 and it belongs to Massari from Genoa (Riahi-Belkaoui<br />
A. 2004), preceding with approximately 150 years Luca Pacioli. But Luca Pacioli is associated with the introduction<br />
of the double game method, in 1494 publishing the book Summa de Arithmetica Geometria Proportioni et<br />
Proportionalita which includes two chapters in which it is presented the double game method. As the accounting<br />
technique was described approximately 700 years ago, also the problems issues of evaluation in accounting have<br />
existed for ages. The reason is that one of the most complicated issues the accounting faced was lanced to the<br />
component elements of the financial <strong>si</strong>tuations, and that it could be provided (offered) credibility and relevance for<br />
the accounting theory and practice there were proposed many evaluation grids among which we mention: historical<br />
cost, present value, correct (proper) value. It is asked the question which of these evaluation grids will be chosen,<br />
taking into con<strong>si</strong>deration the advantages and disadvantages of each of them.<br />
Eventually, the accounting experts reached the conclu<strong>si</strong>on that, b measuring and presenting the accounting<br />
information, the most suitable would be the historical cost, thanks to the advantage offered by its reliability, the<br />
defining clarity coherence, the verifiable character. The historical cost is the cost of origin evaluated, measured and<br />
registered at the appearance of assets and the creation of debits. The general framework of the International<br />
Normali<strong>si</strong>ng Body/Institution – International Accounting Standards Board (IASB) defines the historical cost as: “In<br />
case of assets, the historical cost delimits the amount in cash of equivalents of cash paid at while buying them the<br />
moment of their buying or the proper (correct) value of the paid amount while buying. In case of the debits , the<br />
97
historical cost represents the value of equivalents got by the exchange of obligation or in certain circumstances (for<br />
instance , in case of taxes and profit ) , the value it is expected to be paid in cash or equivalents of cash in order to put<br />
eliminate the debits , while doing bu<strong>si</strong>ness accordingly . The historical cost is the consequence of this fundamental<br />
principle: the principle of the nominal monetary and the principle of prudence (Feleaga L. & Feleaga N, 2007).<br />
The principle of monetary nominalism ignores value fluctuations of the monetary standard and requires evaluation of<br />
goods acqui<strong>si</strong>tioned in onerous title at cost of purchase, of goods obtained through own production means at<br />
production cost, of claims and duties at nominal value. Once assessed, the historical cost remains constant as long as<br />
the good remains in posses<strong>si</strong>on of the manufacturer. Precautionary principle mandates accounting of any potential<br />
devaluation and prohibits accounting latent gains of value afferent to assets. Such, assets remain recorded at<br />
historical cost if they undergo an accrual of value or are otherwise appraised at inventory value, according to<br />
Romanian regulations pertaining or the recoverable amount, for most items, under International Financial Reporting<br />
Standards (IFRS).<br />
Historical cost accounting first developed in the nineteenth century, following the industrial revolution, but has its<br />
origins in the XV century, when first used in textile mills. Gradually, the precautionary principle began to be<br />
instituted in accounting so that now you cannot talk about historical cost accounting without calling into question<br />
this principle of prudence. J. Savary is among the first authors inducting aspects of the application precautionary<br />
principle into accounting. Thus, in his book, �¤�©¢�©£��¡���£©��, released in 1675, Savary J. recommended for<br />
entities the performing of annual inventory appraisement and suggests that stocks should not be assessed at a higher<br />
value than their real value. Likewise recommended is that entities take into con<strong>si</strong>deration all costs undertaken and all<br />
that is owed (B. Colas, 2005).<br />
To be able to rely on information provided by manufacturers, internal and external users should ensure that the<br />
information is verifiable and objective. In as such, it is specifically utilization of the historical cost, as measuring<br />
base that allows entrepreneurs to provide verifiable and objective information in financial statements. (Feleagă N.<br />
1996). Historical cost is past-oriented, but unlike other bases of evaluation, affords a great advantage: it is clearly<br />
defined and verifiable; once established, it remains fixed in as long as the property is in posses<strong>si</strong>on of the<br />
manufacturer. Based on these advantages it seemed that nothing could happen to historical cost. Well, what then is<br />
the great disadvantage making the historical cost value obsolete? The answer: inflation. If market price rises, the<br />
information provided in compliance with the historical cost is not real. In this respect Ristea M. (2004) states "to<br />
circumvent this reality means that fictitious results will con<strong>si</strong>gned to financial records because historical costs<br />
inscribed prior sale are expressed in account units of different value than the value achieved based on sale price."<br />
Without adequately dealing with the result the <strong>si</strong>tuation arises when a firm is recording imposable profit while<br />
actually accumulating loss. In fact, international accounting standards (IAS) number 1 'Presentation of financial<br />
statements' states as follows: "the financial statements based on the historical cost model are useful only if expressed<br />
in relation to the unit of measurement current to the balance sheet at the time of inscription. Another disadvantage<br />
about historical cost accounting is the lack of pertinence regarding inflation to the information provided (D.<br />
Solomons, 1948; B Barlev & Haddad JR, 2003, IK Khurana MS & Kim, 2003; D Herrman et al, 2006).<br />
Thus, following criticism of accounting historical cost, current value assessment began to coalesce. In the year 1886,<br />
german writer Simon H.V., for the first time in accounting, introduced the concept of usage value (present value)<br />
through applying the principle of prudence in evaluating fixed assets, deigning that these must be valued at the<br />
minimum between cost and value of use (B. Colas, 2005). Thus Simon H.V. is more than a century prior to the IASB �¤�¢¤�©�£�������¤��, which, by issuing of IAS 36 uses the present value to determine whether an asset is<br />
deprecated or not. The german Schmild F., published in 1908-1922 a series of articles promoting the use of present<br />
value in accounting evaluation, justified by the fact that, in a market based economy, there are fluctuations in price<br />
making it impos<strong>si</strong>ble to obtain a correct accounting result through a historic cost valuation.<br />
Following the Second World War during the period of reconstruction of national economies, in the '50s and '60s,<br />
inflation was manifest in many countries. Traditional accounting, based on the stable monetary hypothe<strong>si</strong>s and the<br />
application of the precautionary principle, proved unable to faithfully reflecting the picture accounts painted. Models<br />
were proposed as to allow accounting practice to show the impact of inflation has on the financial <strong>si</strong>tuation and the<br />
performance of entity, information that is relevant from an economic and financial viewpoint. It was therefore<br />
necessary to apply measures resulting in the restoration of confidence in financial statements by maintaining the<br />
98
purcha<strong>si</strong>ng power of money. This concept of maintaining the purcha<strong>si</strong>ng power of money had become particularly<br />
important in the world of bu<strong>si</strong>ness because of it highly influencing deci<strong>si</strong>on-making. Thus emerged accounting for<br />
inflation. Gradually, globally, various accounting practices that adapted for inflation were instituted, including:<br />
methods based on conver<strong>si</strong>on (indexed), methods based on assessment (current cost), mixed methods (Tugui A.,<br />
2000). The consequences of inflation for the balance sheet items in general and on capital and reserves, in particular,<br />
have led to legislation, national and international, adopting norms to regulate them.<br />
On the backdrop of discus<strong>si</strong>ons at the European level concerning the reliability vis a vis the relevance of historical<br />
cost accounting, as a first step forward, the Fourth Directive of the European Economic Community allowed the use<br />
of other bases of evaluation as well "Member States may declare that they reserve the right, through derogation from<br />
historical cost assessment, to authorize or to require of all or certain categories of companies the following:<br />
� Assessment based on replacement value for tangible assets whose use is limited in time, and for stocks;<br />
� Evaluation of records inscribed in financial statements, including equity, on the ba<strong>si</strong>s of methods, other than<br />
those referred to in paragraph a), that account for inflation;<br />
� Reevaluation of corporeal fixed assets as well as financial fixed assets.<br />
Based upon these regulations, countries like Britain, Holland, France and Germany have passed laws that match<br />
minimum requirements of these rules. UK is the pioneer in u<strong>si</strong>ng the current (present value) assessment being among<br />
the first countries that permitted revaluation of assets' current value. Under general framework in the UK there are<br />
two bases of evaluation: historic cost and the present value, and the actual, present value can be determined as<br />
follows: min = current value (current cost, recoverable value), where the recoverable value = max (net value<br />
realizable; usage value). From how it is ascertained it follows that the present value reflects more the disposses<strong>si</strong>on<br />
value of assets (A. Haller et al, 1997).<br />
The United States have, for many years, been the champions of the use of historical cost in accounting (Zeff, 2007).<br />
Despite this, however, in September 2006 the U.S. regulating body the Financial Accounting Standards Board<br />
(FASB) published standard SFAS 157 which defines fair value, establishes a conceptual<br />
framework for asses<strong>si</strong>ng the fair value and specifies the information to be presented on the fair value.This regulation<br />
allows and encourages entities to evaluate assets and liabilities at fair value. What was the reason for this radical<br />
change? FASB argued that such a change thusly "... with the passage of time, the historical cost becomes irrelevant<br />
to revealing the current financial <strong>si</strong>tuation of an entity ... financial statements should provide users with information<br />
relevant to investment deci<strong>si</strong>ons, credit or other types of deci<strong>si</strong>ons. " Under this regulation, fair value is defined as<br />
such: "fair value is the price that could be derived from an asset sale or payment in the case of debt transfer in a<br />
normal transaction between market participants at date of valuation." ¤©�§¢¤�¤��� �©£¢¡©¨§¤<br />
At international level, the present value is used more frequently in asses<strong>si</strong>ng the financial po<strong>si</strong>tion and performance<br />
of an entity. Ionascu I. affirmed in 2003 that "At least for the near future, we will witness the abandonment of<br />
historical cost, but instead a joint assessment model, characterized by the cohabitation between the historical and<br />
current value. It is pos<strong>si</strong>ble that the preparation of consolidated accounts should be based more on fair value than just<br />
the drawing up of individual accounts, <strong>si</strong>nce consolidated accounts almost exclu<strong>si</strong>vely serve shareholders and<br />
managers.<br />
At the level of financial entities, historical cost will sub<strong>si</strong>st also because it is and will continue to be required in order<br />
to determine tax base pending tax according to regulations. Jianu I (2009) following study conducted on the impact<br />
of u<strong>si</strong>ng fair value accounting, in the assessment of asset elements, under IFRS framework, noted that "the majority<br />
of asset elements must be assessed at fair value (financial assets available for sale and assets held for trading that are<br />
assessed at fair value, fixed assets held for sale, biological assets and agricultural production valued at fair value less<br />
transaction costs) or may be measured at fair value if the entity should choose this accounting treatment (con<strong>si</strong>dered<br />
ba<strong>si</strong>c treatment in the case of real-estate investment, alternative treatment in case of operating assets and evaluation<br />
and alternative treatment for tangible and intangible assets).<br />
RESEARCH METHOD<br />
Evaluation is the process of determining the value at which financial structures that will be recognized in the balance<br />
sheet and the profit and loss account. This involves choo<strong>si</strong>ng a ba<strong>si</strong>s of evaluation. In accounting theory and practice<br />
99
several bases of evaluation have been suggested, among which the most commonly used are historical cost, current<br />
cost, fea<strong>si</strong>ble value, present value and fair value. Last 4 bases of evaluation show present values.<br />
The durability of historical cost accounting, brought again into discus<strong>si</strong>on by the present trend of utilizing present<br />
values in accounting evaluation, was the starting point in undertaking the present study, which includes the<br />
advantages and disadvantages of asses<strong>si</strong>ng the historical cost vis a vis the evaluation of current value in a<br />
comparative manner.<br />
To execute the comparison we identified 11 po<strong>si</strong>tive characteristics depending on which we analyzed to what extent<br />
each of the two types of assessment - historical cost or current value - is advantageous or disadvantageous.<br />
Subsequently, we extended the study to reflect how the accounting information users are benefited by the assessment<br />
used in the accounts. Finally, as a consequence of the present <strong>si</strong>tuation facing the global economy, we've have<br />
expressed a personal view regarding the type of assessment that should be used in accounting, during an economic<br />
downtrend.<br />

cost, current cost, current value or fair value. The multitude of forms of assessment that can be substituted for the<br />
current value make this concept difficult to understand for users. In addition, complex methods of calculation for<br />
such assessment bases make their use in accounting prohibitive.<br />
requires �¤¨£©�£¨£�<br />
that accounting information may not contain <strong>si</strong>gnificant errors and may not be biased so that<br />
users may be confident it correctly illustrates what it is supposed to denote. Generally, it is an accepted statement that<br />
accounting in historical cost is reliable. However, before accepting this claim one should analyze characteristics<br />
which must be met for accounting information to be con<strong>si</strong>dered reliable: accurate representation, prevalence of the<br />
economic over the juridical, neutrality, prudence and integrality. Historical cost is veracious in inflationary<br />
economies, historical cost accounting is a specific to economies where the legal has precedence over the economic,<br />
the information presented is incomplete because it only con<strong>si</strong>ders data relating to the transaction carried out, without<br />
enacting a comparative study. In contrast, historical cost is neutral because, being registered on certified documents<br />
cannot be manipulated. Also historical cost accounting is prudent as it imposes the principle of prudence. Therefore<br />
historic cost only partially meets the characteristics necessary to allow that the information provided by this ba<strong>si</strong>c<br />
assessment is to be relied upon. Actual value is oppo<strong>si</strong>te historical cost in as far as compliance with features required<br />
to ensure information reliability is concerned. Asses<strong>si</strong>ng the current values faithfully represents reality even in<br />
inflationary conditions, compelling an accurate reflection of economic reality through recognition of items at current<br />
value. However, actual value is not neutral because it is easy to manipulate, for example by presenting some current<br />
values higher than in reality for the purpose of painting a favorable image of the entity to financial institutions.<br />
In addition, accounting in current values is not prudent because it allows the recognition, not just of declines in the<br />
values of assets, but also of gains. Thus, although it is recognized that asses<strong>si</strong>ng in current values unreliable, through<br />
analy<strong>si</strong>s performed, we can appreciate that the reliability, although only partially observed, adapts better to current<br />
value evaluation than assessment in historical costs.<br />
reflects �¤¨¤�©��¤<br />
the usefulness of accounting information, and as<strong>si</strong>sts users in asses<strong>si</strong>ng the events past, present<br />
and future. Asses<strong>si</strong>ng the historical cost is pertinent only to a stable economy. Instead, in an inflationary economy,<br />
the information submitted by historical cost accounting is false because it registers profit as prices increase,<br />
potentially leading to the decapitalization of the entity. Historical cost accounting being relevant only to a stable<br />
economy we believe that it only partially fulfills the qualitative characteristic of accounting information regarding<br />
relevance. In contrast, current value assessment reflects the current economic reality of present transactions, aiding<br />
users in effecting predictions on the financial po<strong>si</strong>tion and future performance of the entity, thus allowing us to state<br />
that the present value provides relevant accounting information for users.<br />
of ����©¢©�£¨£�<br />
accounting information involves issuing predictions both in time, from one year to another, as well<br />
as space, from one economic entity to another. Evaluating in historical costs does not allow for accurate comparisons<br />
because the comparison involves of historical values recognized introduced in accounting on differing dates. For<br />
example, if an entity has three identical lands, each acquired at different dates, they will be registered at instatement<br />
in the financial records at values of, for example, 50 monetary units, 150 mu and 300 mu, respectively. In a historical<br />
cost accounting, the value presented in the balance sheet for these lands will be a total 500 um. It is as if we add 50<br />
apples to 150 pears and 300 oranges. However, current value assessment allows proper comparisons, both in time<br />
and space. Thus, if in our example the actual value of one lot of land would be 300 mu, then the lands would be<br />
figure in the balance sheet at their present value of 900 mu.<br />
Objectivity<br />
A sought quality of historical cost accounting is its objectivity, based on verifiable facts, conscribed in certified<br />
documents which thus satisfies one of the primary purposes of accounting, namely, to serve as evidence among<br />
traders. Objectivity is enhanced by the trust lawyer’s grant to historical cost accounting. The objectivity of historical<br />
cost accounting renders it ea<strong>si</strong>er to control. However, historical cost accounting is not fully objective in the <strong>si</strong>tuation<br />
of accounting drops in the value of assets or hikes in the value of liabilities and, as such, balance sheet items must be<br />
recognized at estimated values that are largely subjective. Instead, asses<strong>si</strong>ng actual values is con<strong>si</strong>dered subjective<br />
because it is based on continuous estimates of current values, estimates that are often based on different methods of<br />
calculation for current values. In addition, the manager can "juggle" the estimates performed to influence current<br />
values for the purpose of submitting a favorable <strong>si</strong>tuation of the entity and the de<strong>si</strong>red and expected outcomes.<br />
Prudence<br />
101
Even <strong>si</strong>nce the early nineteenth century, historical cost assessment abides by the principle of prudence. In the case of<br />
assets, for example, the precautionary principle neces<strong>si</strong>tates accounting potential value drops while precluding the<br />
accounting of latent value gains of assets. Such, assets are recorded at historical cost if there is a growing value or are<br />
otherwise valued at current value that is lowest. According to the principle of prudence only benefits acquired on the<br />
balance sheet date may be recognized. Therefore historic cost is conducive to a negative view of the entity as abiding<br />
by the principle of prudence only allows recognition of potential losses for assets and never of gains. So historical<br />
cost accounting does not foresee all the entity's profits, but anticipates all losses. However, lately, more and more<br />
<strong>si</strong>tuations have lead to the failure of the principle of prudence. Example of this is the revaluation of fixed assets<br />
which requires recognition in equity of the gains of revalued assets. There is also the case of real-estate investments,<br />
which implies recognition in the profit and loss account of the gains in value of real-estate investments if it is opted<br />
for evaluating them at fair value. Currently, even as pertains to debt, the application of the precautionary principle<br />
has been constrained in the sense that only likely liabilities are recognized through admitting of provi<strong>si</strong>oning for the<br />
most accurate estimate pos<strong>si</strong>ble. In case of debts , the prudence principle, demands however to be taken into account<br />
all the foreseeable risks and pos<strong>si</strong>ble loss, even if these are admitted between the end of the financial transaction and<br />
the date on which the financial <strong>si</strong>tuations are being authorized . This demand is still respected only in the accounting<br />
from Germany, a system of accounting where the prudence is applied extremely and, by respecting the principle of<br />
imparity demands that all the foreseeable losses be accounted, as well as all the pos<strong>si</strong>ble debts, not only the pos<strong>si</strong>ble<br />
ones. (Imparitatsprinzip)<br />
The use, to an even smaller extent, of the prudence principle, reveals the present trend of accounting towards an<br />
evaluation in current values. The evaluation at the current value enforces the recognition in accounting, both of the<br />
achieved incomes and the non achieved incomes. In this respect, at present, the accounting equipped with an<br />
instrument adequate to the measurement in accounting of both the achieved results and the non achieved results,<br />
meaning the global result. Although the concept of global result appeared for the first time in 1980 in the American<br />
accounting �¢¤�¤��©�£������¤�£�©��£©¨�£�§©�£���. regulations, there were needed 27 years to be accepted at an international level, by adopting the concept<br />
in IAS 1 Thus, starting with financial practice 2009, all the entities that apply<br />
IFRS must compulsorily make the <strong>si</strong>tuation of the global result, as a main <strong>si</strong>tuation of reporting the financial<br />
performance of an entity. The tran<strong>si</strong>tion from the accounting result to the global result can be con<strong>si</strong>dered a tran<strong>si</strong>tion<br />
from the evaluation in historical costs to the evaluation in current values.<br />
Simplicity<br />
The accounting in historical costs is being characterized through the <strong>si</strong>mplicity of measuring this value. In case of<br />
purcha<strong>si</strong>ng assets, the historical cost is represented by the purcha<strong>si</strong>ng cost, made up of the buying price and all the<br />
accessory expenditures to get the asset workable. If the buying price is easy to be identified because it is on the<br />
justified documents relevant to the input of the asset in the entity, it cannot be told the same thing in case of the<br />
accesory expenditures. Contabilitatea în costuri istorice se caracterizează prin <strong>si</strong>mplitatea măsurării acestei valori.<br />
For instance, it is being dealt with the problem of allotting the expenses with the transportation for the two products,<br />
in case the company purchases two important products at the same transportation. However, the accounting benefits<br />
of urgent methods to allot the indirect expenses, as well as the method of supplementing, ABC method, all these<br />
make this aspect not to be an obstacle anymore. When producing assets, the historical cost is represented by the<br />
production cost which contains the totality of direct and indirect expenses of production made by the entity to obtain<br />
a certain asset. The allotting of the indirect expenses for the products is relatively complex, but the complexity<br />
re<strong>si</strong>des, not so much in the calculus method but the way of adapting the organizational chart of the entity to an<br />
efficient and easy system to calculate the costs.<br />
When evaluating in current values it cannot be spoken about <strong>si</strong>mplicity because the calculus of this value requires<br />
advanced knowledge of evaluation. For instance, when establishing the current cost/ the acceptable value it must be<br />
identified the markets on which the asset could be bought/sold the prices it could be transactioned, the expenses<br />
estimated to be bearded by the entity after the sale when establishing the fea<strong>si</strong>bility value, the criteria of selecting the<br />
most reliable values when more alternatives are being offered etc. The problems are even more complex when<br />
calculating the present value, which supposes estimations of the future cash flows, of the updating rate which must<br />
be taken into con<strong>si</strong>deration when updating the cash flows, the period of time for which the cash flows must be<br />
estimated.<br />
102
Less costly<br />
The costly character of an evaluation ba<strong>si</strong>s refers to the financial effort undergone by entity in order to determine the<br />
value at which the elements must be admitted and presented in the financial <strong>si</strong>tuations. The calculation of the<br />
historical cost do not rise great difficulties because it deals with the identification of the value which is on the<br />
justified documents of input or its calculation, resorting to specific methods of allotting the expenses for the purchase<br />
or the production of assets. Time has demonstrated that the accounting practitioners are able to calculate the<br />
historical cost. The same thing cannot be said about the calculation of the current value. Either we talk about the<br />
current cost, acceptable value, present value or fair value, the difficulties imposed by the calculation of these values<br />
surpasses the capacity and the training of many accounting practitioners. This is the reason for which, other<br />
specialized persons, as evaluators, will be engaged in the calculation of the current values. This thing, certainly,<br />
generate additional costs for an entity, by all means neglected, reason for which we could say the evaluation at<br />
current value is costly.<br />
Exhaustivity<br />
Often it is reproached to the historical cost that it does not allow the evaluation of all the assets as the fixed assets<br />
generated internally, the competences of the personnel. Still we con<strong>si</strong>der that the reproach should be made not in the<br />
manner of measuring these elements but the conditions that should be achieved for their acceptance, admis<strong>si</strong>on in<br />
accounting. It is known that an element, in order to be accepted it must be evaluated in a reliable manner. As the<br />
enumerated elements above are difficult to be quantified and their values vary very much, the accounting information<br />
is no longer reliable, although the real value of such elements is <strong>si</strong>gnificant. Furthermore, there is a series of elements<br />
which at their initial acceptance do not have a value, as the case of the covering instruments which practically should<br />
not be admitted although afterwards their initial admis<strong>si</strong>on they are able to register great variations of value. That is<br />
why it is con<strong>si</strong>dered that the evaluation at current value would not be pertinent, because it allows the evaluation of<br />
these elements. Still the lack of an active market makes it difficult for a series of elements to calculate the current<br />
values such as the current cost and the acceptable value. The calculation is more complex in case of establishing the<br />
present value. The difficulties in establishing the current value for a series of elements belonging to the balance<br />
makes the exhaustively of evaluation be only partial.<br />
Lack of volatility<br />
Volatility reflects the variation of result settled by the use of a certain evaluation ba<strong>si</strong>s. According to the accounting<br />
in historical costs only the achieved incomes can be accepted, their presentation being made in the account of profit<br />
and loss. The variation of the value of assets and debts does not influence the result of the exercise because the non<br />
achieved incomes cannot be admitted only in the moment of selling. Thus the volatility of the result as a<br />
consequence of the evaluation in historical costs, doubled, at international level, by the current politics of<br />
diminishing the number of accounting measures, made the volatility of the result is minimal. In exchange, by<br />
evaluating the assets and debts at the current value, volatility increases because the incomes and the non achieved<br />
losses, resulting from the variation of the elements value belonging to the balance sheet, must be accepted, admitted<br />
in accounting. The current experience, regarding the authorized accounting treatments IFRS, Show that not few are<br />
the <strong>si</strong>tuations which create confu<strong>si</strong>ons regarding the way of admitting in accounting the incomes/non achieved<br />
losses. For instance, in the case of real estate’s investments, the plus of value is admitted in the loss and profit<br />
account, if the entity chooses the method of evaluation at fair value, or at own capitals, if the entity chooses the<br />
reevaluation method. In case of the financial instruments, the problems are even complex because everything<br />
depends on the intention of the entity. Thus, if the shares are clas<strong>si</strong>fied as financial assets owned for transaction, the<br />
plus of value is admitted in the loss and profit account, instead, if the shares are clas<strong>si</strong>fied as available assets for the<br />
sale, the plus is admitted at own capitals. Examples can continue in this respect.<br />
Being aware of the multitude of <strong>si</strong>tuations which require the presentation of the incomes and non achieved losses,<br />
either in the profit and loss account or in the balance sheet, IASB enforced that, starting with the 1-st of January<br />
2009, all the entities applying IFRS should draft the <strong>si</strong>tuation of the global result. Thus the incomes or none achieved<br />
losses, regardless they are admitted in the profit and loss account or in the own capitals, they will influence the<br />
global result. The volatility of the net is sent to the global result avoiding thus the creative accounting of influencing<br />
the net result by choo<strong>si</strong>ng a certain accounting policy.<br />
103
Representing the stock exchange value of the entity<br />
The evaluation at historical costs maintains the assets and the debts of the entity at their origin value. When the<br />
prices on the market fluctuate, most of the times increa<strong>si</strong>ng, the variations of value are not con<strong>si</strong>dered, having a<br />
double influence: on the one hand, upon the balance sheet, because the assets are not presented at their real value but<br />
at their historical value, on the other hand upon the profit and loss account, which shows a result inferior to the real<br />
performances of the entity. The calculation of a decreased result has as a consequence the presentation of the own<br />
capitals at a smaller value than the real value of the entity. Normally, the own capitals should reflect the value of the<br />
entity, but through an accounting in historical values, the own capitals give an accounting value of the entity – which<br />
reflects a sum of historical values admitted at different times but not at all a real value. This disadvantage of the<br />
accounting in historical costs, by none registering all the incomes in accounting (not only achieved but also none<br />
achieved) is empha<strong>si</strong>zed by the non admis<strong>si</strong>on of other <strong>si</strong>gnificant elements whose greatness cannot be estimated<br />
profes<strong>si</strong>onally. It is the case of the fixed assets generated internally (The most relevant example being the<br />
commercial fund), the competences of the staff, the managerial team of the entity. A part from the disadvantages<br />
reminded above is eliminated through an evaluation at current values. We used the word „part” because the<br />
evaluation at current values allows the calculation of the real value of an entity, calculated as an amount of the real<br />
values of the assets and debts of the entity, established individually, but not as a whole. The entity, as a unitary<br />
whole, contains other assets and debts, omitted in an evaluation element by element. It is the case, as I already<br />
mentioned above, of the commercial fund generated internally, of the competences of the personnel, the managerial<br />
team etc. Still, so far, it has not been found a consensus to accept a certain method of evaluation these elements<br />
analyzed individually, being able to be taken in con<strong>si</strong>deration only through an evaluation of the entity as a whole.<br />
Users of the accounting information<br />
The users of the accounting information can be clas<strong>si</strong>fied as follows: primary users (the shareholders) which are the<br />
owners of the entity and who, thus, have a direct interest in the entity , either by taking control if they have a<br />
preferential po<strong>si</strong>tion, or by cashing dividends which should allow the recovery of the entity ; the secondary users that<br />
have a financial interest in the entity ( potential investors, creditors, the state, the employees); the tertiary users (<br />
population that could be affected, either negatively by the pollution generated by the entity , or po<strong>si</strong>tively by the<br />
pos<strong>si</strong>bility of creating new jobs) which have a direct financial interest in the entity but, which are affected, or I<br />
believe it could be affected by the way the entity administers the activity. The financial <strong>si</strong>tuations of the companies<br />
quoted are mainly addressed to the shareholders and the potential investors, but they could be used by other users of<br />
the accounting information such as creditors, the state, employees, suppliers, clients and other users. £��¤���¢�demand pertinent ��¤�¢£�©¢<br />
information on which they could take deci<strong>si</strong>ons�whether to sell or keep the<br />
shares. An evaluation in actual values offers pertinent information because it represents a value close to the real<br />
value of the entity. The accounting in historical costs, although provides reliable information they do not give the<br />
real value of the entity. In order to compensate this disadvantage, the financial analysts used a series of evaluation<br />
methods most of them calculating the value of a company from the current value of the elements analyzed<br />
individually to which it is added the goodwill and the badwill created by the entity. At present, maybe more than the<br />
result established by the accounting in historical costs, the shareholder is interested in the calculation of another<br />
indicator: EVA (economic value added) which shows if the entity is able to create value for the shareholder, too. £��¤���¢�demand a ��¤�¤����©¢<br />
prudent accounting because they provide the safety of the financial resources with<br />
which they financed the entity. The evaluation at current costs leads to the diminishing of the producing capacity of<br />
the entity, when the plus of value are estimated at higher values than the real ones, or when they are not achieved in a<br />
short period of time. Thus the integration plus the potential values in advantage could have as a consequence the<br />
distributing of dividends which do not correspond to the achieved results and the availabilities available of the entity<br />
that could lead to the financial unbalance and the diminishing of the cofinancing capacity. In this context, the<br />
prudence principle, specific to the accounting in historical costs, seems to meet the requirements of the secondary<br />
investors. Thus, respecting this principle, on the one hand, protects the creditors and keeps their trust and, on the<br />
other hand, it eliminates the risk of distributing fictitious dividends, prone to affect the financial balance of the entity<br />
and its development, with direct consequences upon the employees. Furthermore, the result calculated by the<br />
accounting in historical costs represents the support for the calculation of the tax owed to the state.<br />
104
£��¤���¢�©¢¤interested, not in the financial information presented by the financial <strong>si</strong>tuations, but special<br />
reports through which there are presented non financial information regarding, on the one hand, information about<br />
the entity politics upon the natural environment, the obtained results and the commitments regarding the protection<br />
of environment, the way the entity activity affects the natural environment and, on the other hand, social information<br />
such as: remuneration, training, working conditions, social climate etc. �¤¢�£©¢<br />
Pertinence in economic cri<strong>si</strong>s <strong>si</strong>tuations<br />
There are some definitions of the cri<strong>si</strong>s concept, but all have some common characteristics: represents a critical<br />
moment, it releases suddenly, through a sudden and brutal changing of a state, represents a dangerous moment, a<br />
weighty <strong>si</strong>tuation, inducing a ten<strong>si</strong>on period. Macroeconomic speaking, economic cri<strong>si</strong>s, that manifests by production<br />
diminution and unemployment growing, has as a direct effect price diminution on the market. This last fact<br />
influences accountancy evaluation. If in inflation conditions evaluation at actual values offers pertinent, in pertinent<br />
conditions, accountancy in historical costs, with prudence principle, is in the same pertinence manner.<br />
In decrea<strong>si</strong>ng price conditions, accountancy in historical prices delivers a result that represents the difference<br />
between the pos<strong>si</strong>ble income from the transaction made in a period (lower, effect of prices’ diminution) and the<br />
expense evaluated in historic prices corresponding to those incomes (bigger because they are due to the former<br />
periods, when the values at which were evaluated the elements at the entry date were bigger). So the result is<br />
minimum, which allows conserving the production entity capacity by distribution of a lower sum as dividends and by<br />
value entry reconstruction of the active at their historic costs.<br />
The presentation of the pertinent information, in cri<strong>si</strong>s conditions, is reflected over the balance sheet. We say this<br />
because by respecting the prudence principle, all value decrea<strong>si</strong>ng are taken in con<strong>si</strong>deration, so the actives are<br />
reflected at their real value, decreased because the cri<strong>si</strong>s.<br />
CONCLUSIONS<br />
The historical cost reflects the right value of the elements at the initial recognition moments, being a just value for<br />
that date. But once the time passes by, he takes a really big historical aspect. In a stable economy, most of the<br />
accountancy information users con<strong>si</strong>der accounting pertinence in historical costs. But the economic parameters, the<br />
general ones (power of buying, interest rate) and the specific ones (the firm profitability) don’t stop developing.<br />
Thus, in a perennial existence in accounts, the historical cost of an element can’t return, after a specific period, the<br />
devoted image of the value that should be reflected. This fact becomes invi<strong>si</strong>ble in inflation conditions, when the<br />
calculated result by accountancy in historical conditions doesn’t reflect reality. It’s the reason for, in an inflation<br />
conditions must gave up at historical accountancy and accept accountancy in these times. In exchange, in economical<br />
cri<strong>si</strong>s time, accountancy in historical costs is properly because it doesn’t allow distribution of fictive dividends and<br />
prudence accounting which imposed is adapted to the deci<strong>si</strong>ons which should be taken in a <strong>si</strong>tuation like this. But, in<br />
present, internationally speaking, it is tended to an evaluation in actual values that probably in some years will take<br />
place to the accounting in historical prices. It remains to see in what measure accounting in recent values will be<br />
durable as accounting in historical costs.<br />
This study analyses, thoroughly, the advantages and disadvantages of accounting in historical costs towards<br />
accounting in current values. A more detailed study, through the analyses of many characteristics, can be the purpose<br />
of future approaches on this topic. Future researches could be enriched through the study of the evaluation bases in<br />
the context of concepts in order to maintain the capital.<br />

WHAT IS AT THE BACK OF THE WAGE COSTS?<br />
Daniela Nicoleta Medintu, Iulia Ana Stroe<br />
In the context of profound changes of our time relating to the introduction and use of new methods,<br />
principles and technologies, accompanied by new forms of work organization, the human factor has become a<br />
valuable and strategic factor for any organization. Success in any field of socio-economic activity can be ensured<br />
only through rational and efficient use of human resources. In the contemporary economy, audit of the information<br />
existing in the financial statements plays a crucial part in increa<strong>si</strong>ng the users confidence. Under cri<strong>si</strong>s conditions,<br />
correct and complete record of human wage raise questions. Thus, our objectives were to audit the wage costs, an<br />
important element in the overall audit. The methodology approach con<strong>si</strong>sted of checking the accounting documents<br />
where these expenses are recorded, as well as their compliance with the amounts included in work agreement. We<br />
had in view determining an as fair and proper <strong>si</strong>ze of the expenditure of labor as pos<strong>si</strong>ble influencing the profit or<br />
loss resulting from operating. At present, economic and financial performance of the companies is influenced by the<br />
performance of human resources and so of the expenditures with them in comparison with the previous century,<br />
when the focus was on the technological progress and less on human resources. In conclu<strong>si</strong>on, the continuation of the<br />
bu<strong>si</strong>ness of an enterprise depends on the faithful mirroring of the wage recorded in the accounting.<br />
Keywords: audit, wage costs, payroll, contributions to state budget, wage fraud<br />

1. Introduction<br />
Today, the human factor is launching on deci<strong>si</strong>ve po<strong>si</strong>tions in the issues critical in making efficient firms.<br />
Thus it becomes necessary to research in detail the factors that influence the individual performance of the employee,<br />
determining the optimum <strong>si</strong>ze of the expense with labor and social protection compared to his performance leading<br />
eventually to increa<strong>si</strong>ng the performance of the organization.<br />
The specialty literature in management brings to the fore front the most important resource for bu<strong>si</strong>ness and<br />
for achieving the performance, namely the man. At the same time, in the accounting efforts are made to frame the<br />
knowledge held by employees under the heading of intangible assets.<br />
Evaluation of human capital through the prism each of us was knowledge represented and represents one of<br />
the major challenges the researchers and even bu<strong>si</strong>ness people are facing today. Is it fair the appreciation of human<br />
capita through the wage only?<br />
Research in the field of accounting concerning recording and evaluation of human capital is in progress. In<br />
order to be recognized in the accounting, human capital should be assessed as reliable. Most of those who have<br />
studied the issue believe that the added value brought by a new employee is not reduced to the <strong>si</strong>ze of salary only.<br />
However, there were no rules developed in this field, the value of human capital being further equivalent to the<br />
amount of the salary. Under these circumstances what is at the back of the salary, so that it is con<strong>si</strong>dered as<br />
sufficient the appreciation of human capital at this value?<br />
The human factor requires that organization pays increased attention to the way the employees may be<br />
motivated. Motivation can be done particularly u<strong>si</strong>ng the best methods of remuneration (incentives, rewards, etc.).<br />
Although motivation is a complex process, the people having different needs, different objectives, most<br />
organizations con<strong>si</strong>der remuneration the only way to motivate employees.<br />
2. Ba<strong>si</strong>cs on wage costs<br />
The pay system may be approached from 3 viewpoints:<br />
1. Financial balance:<br />
Ability to pay >=Wage fund<br />
Wage fund means all the expenses related to remuneration of labor<br />
2. External coherence:<br />
107
It must take into account the average level of remuneration in the bu<strong>si</strong>ness sector where the company<br />
operates and the minimum wage level guaranteed by the state.<br />
3. Internal Equity:<br />
Even if the concept of pay equity is a concept difficult to establish, it is clear that the sense of injustice<br />
expressed or experienced by the employee is bearer of potential conflict or is a motivation factor. This concept<br />
covers two aspects: wage-related to qualifications and performance related to pay.<br />
The salary fund correlated with labor productivity represents the main expenditure influencing the total cost<br />
recorded by the company.<br />
Expenses with the salary fund structured as follows:<br />
- Management allowances as fixed amount or included in the salary;<br />
- Wage rate;<br />
- Seniority increases, night hours, special conditions, dangerous conditions;<br />
- Rewards - bonuses, table tickets;<br />
- Contributions, social security paid by the employer.<br />
The wage rate called the ba<strong>si</strong>c salary represents the benchmark for a specific job and is expressed in annual<br />
or weekly amounts. The wage will increase depending on labor productivity achieved. Forms of pay applied in<br />
companies are: on cost, direct individual or collective agreement, by quota percentage. The ba<strong>si</strong>c salary multiplied by<br />
the number of employees makes up the salary fund. Wage fund is increased with the percentage shares in the<br />
agreement achieved, to which are added all the salary increases applied, resulting the gross total.<br />
Compensation is one of the main elements of an employment agreement that is the monetary counterpart of<br />
the services provided )on the one hand and one of the means the company has to retain the best employees and to<br />
attract candidates to join the current staff, on the other hand. For most employees this is the only source of income,<br />
but also for many companies it is a major element of cost.<br />
Compensation occurs most often in the form of money, the record for the organization is a wage expense<br />
influencing company performance.<br />
Wage costs are included in both direct and indirect form.<br />
Wage costs represent all direct costs related to the labor force used, which can ea<strong>si</strong>ly be attributed to<br />
economic and specific unit of product (e.g. wages and their associated elements, generated by the employment<br />
contract and the law relating to workers whose activity is directly linked to the production process). Expenditure with<br />
the labor force used in production related activities, which cannot ea<strong>si</strong>ly be attributed to economic and specific units<br />
of the product are highlighted in the accounts as indirect expenses (e.g. managers or guard salaries). These indirect<br />
costs concerning labor force represents a component of indirect costs of production.<br />
Regardless the forms it takes, be it a direct or indirect, wage costs represent costs for the company.<br />
3. Audit of wage costs-argument in solving of problem researched<br />
The overall objective of the wage costs audit con<strong>si</strong>sted of checking the correct and complete record of wage<br />
costs and of their related contributions as well as their faithful mirroring in accordance with the law in force.<br />
In most audit mis<strong>si</strong>ons the risk of the existence of <strong>si</strong>gnificant errors is minimum, despite the fact that wages<br />
account for a <strong>si</strong>gnificant percentage of the total expenditure. There may be three causes explaining minimizing the<br />
risk as concerns wage costs, namely:<br />
• in case of irregularities, employees will complain to their superiors they were not paid enough;<br />
• operations related to salaries are usually uniform and <strong>si</strong>mple;<br />
• operations related to salaries are rigorously checked by the fiscal bodies in respect of their contributions to<br />
the state budget.The method of wages calculation is not variant during time, in content and value. Due to the<br />
<strong>si</strong>milarity of the calculation method, of the salary in various fields of activity, high quality software is available<br />
quality, by which its record can be kept. Its use reduces the risk of <strong>si</strong>gnificant errors occurrence.<br />
At this stage we have showed the objectives to be pursued in the audit of the wage costs and the tests<br />
needed to be applied.<br />
The auditor outlines and conducts the inspections program in accordance with the objective and purpose of<br />
audit engagement and conducts the audit procedures to be applied.<br />
In applying these procedures, the auditor may use techniques such as: inquiry and analy<strong>si</strong>s, assessment / reassessment,<br />
comparison, other verification of accuracy, observations, inspections of records and documents,<br />
evaluations and inspections of obtaining confirmations. Procedures application allows the auditor to obtain sufficient<br />
information for the report.<br />
The auditor checks the accuracy of the registration and if these wage costs were accurately recorded in the<br />
accounting system and if they are supported by appropriate evidence and documents.<br />
108
The auditor exercises profes<strong>si</strong>onal judgment to obtain sufficient checking evidence appropriate to determine<br />
if these expenditures were made (the reality and quality of the costs).<br />
3.1. Accounts involved in the wage payment process<br />
Within the wage payment process the company observes certain steps in the calculation and recording of<br />
salaries and their related contributions as well as their payment.<br />
The first step is the registration of the wage costs due to employees. The second step is to record employee<br />
contributions to the state budget as well as of the respective tax due. Further, the company records its debts to the<br />
state budget related to the salary fund <strong>si</strong>multaneously with the debit of their related expenses accounts. At the end,<br />
the amounts due to employees and the state budget, are paid, the debts previously recorded being annulled thus.<br />
Employment, liquidation, authorization and payment are the four elements of expenditure relating to wage<br />
costs.<br />
For a better understanding of correlations between accounts we achieved the figure below to underline<br />

The stages concerning the wage costs outlined above should be performed based on justifying documents<br />
containing all the information needed for the registration, calculation and evidence of salary structure elements.<br />
When employed, the future employee <strong>si</strong>gn the employment agreement and acknowledges the provi<strong>si</strong>ons in the<br />
collective labor agreement specific to the company where he will further work. He is informed about the duties and<br />
obligations to be met within the job he is charge up and also is acknowledges the labor standard. The employee shall<br />

3.3. Carrying out wage costs audit<br />
In order to understand what is in the back of the wage costs, we have resorted to carrying out mis<strong>si</strong>ons of<br />
audit with the special purpose, namely auditing wage costs.<br />
110
� Objective: Correct clas<strong>si</strong>fication of salary operations.<br />
Tests applied:<br />
o Clas<strong>si</strong>fications of operations related to salaries are compared with the chart of accounts or to the<br />
accounting procedures manual.<br />
� Objective: the evidence of the human resources , working time and a wages (criterion of reality).<br />
Tests applied:<br />
o Checking documents related to this record: individual employment contracts, collective labor<br />
contract;<br />
o Checking human resources policies;<br />
o Checking presence sheet;<br />
o Checking payrolls to identify new employees or employees which left the company and the<br />
compliance with employment agreements respectively with the deci<strong>si</strong>on of cancellation of the employment<br />
agreement changes of ba<strong>si</strong>c salary, of the po<strong>si</strong>tion and facing with the addendum attached to the employment<br />
agreement;<br />
o Checking working time actually worked with the presence sheet and the compliance with working<br />
time in the employment agreement (full time 8 hours per day or part-time minimum 1 hour / day);<br />
o Checking if night hours in the presence sheet are recorded in the payrolls, if they are properly<br />
calculated and<br />
for those who have at least 3 hours of night / day, benefit either of working program reduced by 1 hour compared to<br />
the normal duration of the work day, without resulting in lower base salary or in a 15% and 25% salary growth, of<br />
the ba<strong>si</strong>c salary. We checked if those working in night shift are minimum 18 years old (those under 18 years may<br />
notwork in night shifts), and pregnant or confinement women may not be required to work in night shifts, therefore if<br />

4. Methods of fraud related to wages<br />
As a result of the fact the auditor bears <strong>si</strong>gnificant respon<strong>si</strong>bility for detecting fraud and error, he must<br />
assure that these do not exist. Since most operations related to salary involve a transfer of money means there is an<br />
inherent risk of wage fraud.<br />
Wage fraud is among the greatest encountered fraud committed. Often an employee is set in the fictitious<br />
system of wage and salary payments are made automatically (meets in the payment of salaries through bank cards).<br />
Another common fraud is pos<strong>si</strong>ble if the employee no longer works in the company, but he still appears on the<br />
payroll as paid in another bank account.<br />
There are several ways in which employees can fraud a company in the wage field.<br />
The most common methods of fraud are non existing employees and no fraud concerning hours worked.<br />
Payment of wages on behalf of persons not working in the organization can be achieved by continuing to<br />
pay an employee after the employment has been terminated. Usually the person who commits this type of diver<strong>si</strong>on<br />
of assets is an employee respon<strong>si</strong>ble for recording the wages or who deals with descriptions of timekeeping sheets.<br />
One way to test payments to fictitious employees is to confront the information recorded in the records of<br />
wages with the human resources department to determine whether those employees were actually employed during<br />
the period of payment of wages.<br />
Continuing the payment of salaries to employees who are no longer working in the company can be tested<br />
by examining the pay period following termination of employment, to confirm that the employee's salary may be<br />
paid in the future.<br />
Frauds on the number of hours worked occur when an employee reported more hours than actually worked.<br />
The discovery of the fraud of this type by the auditor is generally very difficult due to the lack of evidence. One way<br />
would be to compare <strong>si</strong>gnatures on various timekeeping sheets to see if an employee has <strong>si</strong>gned on behalf of one or<br />
more persons.<br />
Employees are not only inventive in terms of wage fraud.<br />
Companies also develop different ways of circumventing the contributions applied wages.<br />
112
Motivating employees is increa<strong>si</strong>ngly difficult, they de<strong>si</strong>ring higher net wages. Although the income tax of<br />
individuals and certain social contributions have diminished, however each worker costs actually over 60% in<br />
addition to his net salary.<br />
Therefore the total cost of an employee is 1.6 * net salary, which is actually the value of the work of the<br />
employee. Any benefit brought directly to any employee, means 60% in addition of that amount to the state budget,<br />
amounts that employees do not find included in their daily life.<br />
Because such levies, taxes, fees and other forms of taxation, the employee will reach over 60% less of the<br />
value of their work.<br />
If we take into account the application of the value added tax, the taxes increase. For example as shown at<br />
the beginning of the paper, wage costs are included in calculating the cost of the product or the provi<strong>si</strong>on of services.<br />
At the value of the product or services the value added tax related to the sale is applied. Therefore companies pay<br />
value added tax and wage costs.<br />
In conclu<strong>si</strong>on, some companies seek to reduce these taxes in various forms Within the audit mis<strong>si</strong>on of<br />
salary expenditures, these must be identified to avoid tax.<br />
Among the ways to avoid or minimize taxes, contributions and taxes related to the payroll include:<br />
• Wage class the employee within a minimum working time and then the conclude a cooperation agreement with the<br />
employee as an authorized natural person;<br />
• Setting minimum wages for the employee and then "pay on the black" it;<br />
• Replacement of a part of salary by gift tickets;<br />
• Replacement of the bonus with rewards in kind as tours, training, expenses that the company will not pay as salary,<br />
so no taxation will be applied on them.<br />
5. Conclu<strong>si</strong>ons<br />
Human capital is an essential element of market value of companies, this being also the motivation of our<br />
research.<br />
This paper is set up as a very important ba<strong>si</strong>s of information for any auditor who is in an audit mis<strong>si</strong>on<br />
related to salary expenses or mis<strong>si</strong>on of financial audit, where the audit of such expenses represents an integral part.<br />
The auditor has to plan and perform the audit having regard that fraud may exist at the level of wages as showed in<br />
the paper.<br />
Recognizing the wage costs and keeping records in accordance with the reality represents a key process in<br />
all the costs of a company.<br />
Wage costs influence all the accounts based on which accounting information users make economic<br />
deci<strong>si</strong>ons. They are included in the balance sheet as liabilities related to employees and the state budget in the profit<br />
and loss account, and they are empha<strong>si</strong>zed in the treasury cash flow by payments related to them.<br />
Therefore, the correctness of these expenditures is obvious their influence on the financial statements and<br />
implicitly on the result, which leads to a long-term influence on the company bu<strong>si</strong>ness continuity, the ba<strong>si</strong>c<br />
principle in a contemporary economy.<br />

Introduction<br />
Globalization, although it is often talked about as the reason of much turbulence and change, is in fact the<br />
term used for the collective effect, the change that happens as a result of global implication. Globalization is caused<br />
by four major forms of capital movement throughout the global economy meaning: Human Capital, Financial<br />
Capital, Resource Capital and Power Capital.<br />
Globalization can be seen as a worldwide phenomenon of technological, economic, political, behavioural<br />
and cultural exchanges brought and made pos<strong>si</strong>ble by modern communications, transportation and legal<br />
infrastructures although we have to admit that phenomenon’s like globalization have been spotted way before in<br />
history .So we can conclude that it is a term used to describe how human beings are becoming more intertwined with<br />
each other around the world economically, politically and culturally.<br />
Impacts of globalization can be seen at every step in every field, because of the global village effect we can<br />
see improvements in economy, politics, medicine, learning, trade and commerce, transportation and many others.<br />
Some impacts are also two-<strong>si</strong>ded because of the ever growing interdependencies between countries in a series of<br />
fields because of the increa<strong>si</strong>ng volume and variety of cross-border transactions of services and goods, the fast<br />
diffu<strong>si</strong>on of technology and increa<strong>si</strong>ng less strict legislations.<br />
Globalization should be seen through a human perspective. Many recognize the opportunities for a better<br />
life that globalization offers. I believe their “hopes are realizable, but only if globalization is subjected to better<br />
governance at all levels. More people than ever before do not want to be left behind by the globalization train; but<br />
they want to be sure where it is heading, and that it is travelling at survivable speed.” (World Commis<strong>si</strong>on on the<br />
Social Dimen<strong>si</strong>on of Globalization, 2004)<br />

Globalization – an overview<br />
There are several subdivi<strong>si</strong>ons of globalization and the most important are globalization of politics, of<br />
investments, globalization of trade, globalization of culture and technology. The globalization of trade refers to the<br />
existing fact that people have wider and greater access to a huge number of products and services than ever seen<br />
before. When we speak of international rules and laws made by governments to protect issues such as investment,<br />
trade, human rights and many others, than we are referring to the globalization of politics. “The globalization of<br />
investment takes place through Foreign Direct Investment, where multinational companies directly invest assets in a<br />
foreign country, or by indirect investment where individuals and institutions purchase and sell financial assets of<br />
other countries.” (Oduroye, 2007)<br />
Because of the very fast speed that information travels these days through media, trade and, of course, travel<br />
and of the trends that are launched and ideas we also have to deal with a globalization of culture like for example a<br />
consumer in Romania can enjoy the same pair of Nike shoes as a consumer in China.<br />
The other aspect of globalization is the revolutionary changes in technology, especially in transport and<br />
communications, which has made the world a global village. Transportation costs have come down as a result of<br />
technological advances that make foreign markets more acces<strong>si</strong>ble to trade. Without the electronic means, billions of<br />
dollars in assets and currencies could not be exchanged daily around the globe.<br />
One thing we really have to con<strong>si</strong>der is that globalization is in my point of view a very popular subject<br />
nowadays. If we take into con<strong>si</strong>deration “the unlimited freedom of capital movement and the almost total freedom of<br />
migration, the world by 1914 was maybe even more globalized than today.” (Della Posta, Uvalic, 2008)<br />
Globalization is also unfair and not uniform because while advanced economic countries raise barriers<br />
against imports from less developed countries and in the same time they sustain the idea of free trade concerning<br />
their own exports.<br />
It should be obvious for us that globalization has “different effects for different countries and different<br />
groups of people it would be impos<strong>si</strong>ble to bring the same opportunities or challenges to all countries at the same<br />
time. “ (Della Posta, Uvalic, 2008)<br />
Because of the different perceptions and opinions on globalization let’s try and see some of the<br />
opportunities and threats of this phenomenon. Some opportunities we can specify are the change in the divi<strong>si</strong>on of<br />
labour meaning in terms of production, aggregate demand and lower rates of unemployment; market unification in<br />
improving and making more efficient the markets and the price mechanism by liberalization of trade between<br />
countries and also investment. Another opportunity is that it can produce a lower inflation because it favours a higher<br />
penetration of imports from low-cost producers’ countries.<br />
There are also pos<strong>si</strong>ble negative aspects of globalization like fragmentation of structural conditions, reduced<br />
autonomy of national economies, instability brought by the plurality of economic models and problems in the<br />
governance of the global economy.<br />
The driving spirit has been to make globalization a po<strong>si</strong>tive force for all people and countries. There are no<br />
panaceas or <strong>si</strong>mple solutions; instead a new perspective on globalization should be adopted. In my opinion the<br />
dominant perspective on globalization must shift more from a narrow preoccupation with markets to a broader<br />
preoccupation with people.<br />
The great value of human capital<br />
Companies are recognizing the importance of investing in their employees now more than ever before.<br />
Companies are beginning to understand that to stay on top in the global economy; they need to place more<br />
and more empha<strong>si</strong>s on developing and retaining their people.<br />
Derek Stockley, defines human capital as “recognition that people in organizations and bu<strong>si</strong>nesses are an<br />
important and essential asset who contribute to development and growth, in a <strong>si</strong>milar way to phy<strong>si</strong>cal assets such as<br />
machines and money. The collective attitudes, skills and abilities of people contribute to organizational performance<br />
and productivity. Any expenditure in training, development, health and support is an investment, not just an<br />
expense.” He continues to say, “Competition is so fierce and change is so fast, that any competitive edge gained by<br />
the introduction of new processes or technology can be short-lived if competitors adopt the same technology. But to<br />
implement change, their people must have the same or better skills and abilities.” (Stockley) It is noticeable a change<br />
in clients' strategic values from the tangibles to the intangibles.<br />
115
Nobel Prize-winning economist Gary S. Becker says that “the ba<strong>si</strong>c resource in any company is the people.<br />
The most successful companies and the most successful countries will be those that manage human capital in the<br />
most effective and efficient manner.”<br />
Human capital is a valuable concept because it recognizes that people should be treated as assets, rather<br />
than as an expense.<br />
Economists regard expenditures on education, training, medical care, and so on as investments in human<br />
capital. They are called human capital because people cannot be separated from their knowledge, skills, health, or<br />
values in the way they can be separated from their financial and phy<strong>si</strong>cal assets.<br />
From the globalization human capital focuses on the economic behaviour of individuals, especially on the<br />
way their accumulation of knowledge and skills enables them to increase their productivity and their earnings and<br />
implicit to increase the productivity and wealth of the societies they live in. The underlying implication of a human<br />
capital perspective is that investment in knowledge and skills brings economic returns, individually and therefore<br />
collectively.<br />
If we leverage the importance of human capital in<strong>si</strong>de an organization, then we will also raise the<br />
importance of human capital globally. Human capital is increa<strong>si</strong>ngly recognized as a key competitive advantage for<br />
companies, as well as a key indicator of a company’s success. This is partially the result of the move from a<br />
manufacturing to a service economy. In conclu<strong>si</strong>on it is important for organizations to measure and report on HC<br />
management if they want to control, monitor and better invest in their ‘most valuable asset’. This has become even<br />
more imperative with the growing body of evidence that effective HC management is directly correlated to<br />
performance, competitiveness and ultimately, shareholder value.<br />
De<strong>si</strong>gning the measures to evaluate HC management is the first step and requires linking the indicator to a<br />
key performance driver that will be in line with the bu<strong>si</strong>ness strategy. Measuring and reporting is a second step that<br />
can demand management commitment and resources yet will produce invaluable in<strong>si</strong>ght to both external and internal<br />
audiences. The objective is to as<strong>si</strong>st these different stakeholders to make better deci<strong>si</strong>ons that will benefit the<br />
company. As shown by Figure nr. 1, the risk of human capital is the most <strong>si</strong>gnificant from an organization‘s point of<br />
view.<br />

Human development is about putting people at the centre of development. It is about people realizing their<br />
potential making the best of their capabilities, increa<strong>si</strong>ng their power of choice and enjoying the freedom to lead lives<br />
they value. Since 1990, annual Human Development Reports have confronted several challenges including poverty,<br />
gender, democracy, human rights, cultural liberty, globalization, water scarcity and climate change.<br />
The Human development Report starting from the one which is going to be complete this year and going<br />
back to the one in 1999 has taken a very important stand in explaining how important is to have see the human face<br />
of globalization.<br />
Migration in<strong>si</strong>de frontiers and also out<strong>si</strong>de them, has become an increa<strong>si</strong>ngly important theme in domestic<br />
and international debates, and is the topic of the 2009 Human Development Report (Human Development Report<br />
2009). “The starting point is that the global distribution of capabilities is extraordinarily unequal, and that this is a<br />
major driver for movement of people. Migration can expand their choices– in terms of incomes, acces<strong>si</strong>ng services<br />
and participation, for example -- but the opportunities open to people vary from those who are best endowed to those<br />
with limited skills and assets. These underlying inequalities, which can be compounded by policy distortions, will be<br />
a theme of the report. “(Human Development Report 2009)<br />
There are a series of facts that draw our attention to the po<strong>si</strong>tive impacts of migration on human<br />
development, through such facts as increased household incomes and improved access to education and health<br />
services. Also migration can empower traditionally disadvantaged groups, in particular women. And at the same<br />
time, risks to human development are also present where migration is a reaction to threats and denial of choice, and<br />
where regular opportunities for movement are constrained.<br />
National and local policies in<strong>si</strong>de countries play a critical role in permitting better human development<br />
outcomes for both those who choose to move in order to improve their state of living, and those forced to relocate<br />
due to conflict, environmental degradation, or other reasons. “Host country restrictions can raise both the costs and<br />
the risks of migration. Similarly, negative outcomes can arise at the country levels where ba<strong>si</strong>c civic rights, like<br />
voting, schooling and health care are denied to those who have moved across provincial lines to work and live. The<br />
HDR09 will show how a human development approach can be a means to redress some of the underlying issues that<br />
erode the potential benefits of mobility and/or force migration.” (Human Development Report 2009)<br />
Human development indices calculated for progress as shown in Figure nr. 2 and Figure nr.3 show a great<br />
discrepancy between countries. There are three categories in which the analyzed countries fall: high, medium and<br />
law human development and than they are clas<strong>si</strong>fied according to their progress on long, medium or short term.<br />

Global markets, global technology, global ideas and global solidarity can leverage the lives of people<br />
everywhere. The challenge is to ensure that the benefits and effects are shared equitably and justified and that this<br />
increa<strong>si</strong>ng interdependence works for people not just for the profit of some collectives or countries.<br />
Of course if we think about it globalization is not new, but the present era of globalization, driven by<br />
competitive global markets, is outpacing the governance of markets and the repercus<strong>si</strong>ons on people. Characterized<br />
by “shrinking space, shrinking time and disappearing borders, globalization has open the door to opportunities.”<br />
(Human Development Report 1999)<br />
“Breakthroughs in communications technologies and biotechnology, if directed for the needs of people, can<br />
bring advances for all of humankind. But markets can go too far and squeeze the non-market activities so vital for<br />
human development. Fiscal squeezes are constraining the provi<strong>si</strong>on of social services. A time squeeze is reducing the<br />
supply and quality of caring labour. And an incentive squeeze is harming the environment. Globalization is also<br />
increa<strong>si</strong>ng human insecurity as the spread of global crime, disease and financial volatility outpaces actions to tackle<br />
them.” (Human Development Report 1999)<br />

Globalization we can argue that it needs leadership because people in all the corners of the world are<br />
becoming connected and affected by phenomenon’s and events in the oppo<strong>si</strong>te part of the globe, the poor segment of<br />
countries and people risk being pushed to the margin, because having a stronger governance we can preserve the<br />
opportunities that a competitive market has to offer regulated by specific rules and limits and stronger accent can be<br />
put on human development. Leadership is also needed in order to implement as a global goal to decrease as much as<br />
pos<strong>si</strong>ble the gap between rich and poor countries as we can observe in Figure nr.4 and to increa<strong>si</strong>ng the right of<br />
choice and also have a higher degree of equity.<br />
The human face of globalization<br />
We have to look at globalization through the eyes of the people, ri<strong>si</strong>ng above our setbacks and capturing<br />
faithfully the hopes and fears of our humanity.<br />
Globalization must be brought from the cold corporate board rooms and cabinet government, to meet the<br />
needs of people in the communities in which they live. The social dimen<strong>si</strong>on of globalization is about jobs, health<br />
and education – but it goes way far above these “in their daily life and work: the totality of their aspirations for<br />
democratic participation and material prosperity. A better globalization is the key to a better and secure life for<br />
people everywhere in the 21st century. (World Commis<strong>si</strong>on on the Social Dimen<strong>si</strong>on of Globalization, 2004)<br />
A process by which such a perspective can be realized is one that can be implemented at all levels,<br />
beginning with empowered local communities and improved and more accountable national governance; fair global<br />
rules applied fairly; and global institutions that are more pro-people.<br />
The current trend of globalization must change, too few share in its benefits. Too many have no voice in its<br />
configuration no influence on its causes and effects.<br />
“The results of globalization are what we all make of it, they depend on the policies, rules and institutions which<br />
govern its course; the values which inspire its actors; and their capacity to influence the process.” (World<br />
Commis<strong>si</strong>on on the Social Dimen<strong>si</strong>on of Globalization, 2004)<br />
The governance of globalization must be based on universally shared values and respect for human rights<br />
and morality. The moral and ethical lack of globalization is, where market success and failure have tended to become<br />
the ultimate standard of behaviour, and where the one who is on top and has the higher degree of power takes<br />
everything and weakens the structure of communities and societies. We are dealing with a some what de<strong>si</strong>re by<br />
people to reaffirm ba<strong>si</strong>c ethical values in public life, as seen, for example, in calls for a more ethical globalization.<br />
Values are also the driving force behind the many public campaigns for universal causes, ranging from the<br />
abolition of child labour to the banning of landmines.<br />
The human factor intervenes, where economic cri<strong>si</strong>s is attributed to purely behavioural factors such as lack of<br />
motivation, lack of discipline, and lack of social respon<strong>si</strong>bility. “Greater direct experience of economic cri<strong>si</strong>s was<br />
con<strong>si</strong>stently associated with more endorsement of all three factors, a finding that is broadly con<strong>si</strong>stent with recent<br />
HD initiatives in Thailand and elsewhere in the region, towards greater inclu<strong>si</strong>on, in development policy initiatives,<br />
for managing economic cri<strong>si</strong>s, of the human factor” (Carr et al., 2002)<br />
Human nature is part of the blame for the current economic cri<strong>si</strong>s; we have actually lost our balance we<br />
should even con<strong>si</strong>der according 10% of 700 billion dollars to keeping low income people in their homes.<br />
Those at the top who made bad deci<strong>si</strong>ons are actually still getting rich in consequence, those at the bottom<br />
of economic standard who didn’t made the bad deci<strong>si</strong>ons and who participated the least, are the ones who are<br />
suffering the most .Some might argue that self interest and higher goals are a good perspective but the biggest<br />
challenge in my opinion is to keep that self interest from harming others.<br />
The way you make a lot of money and you create wealth for your self is by providing goods and services<br />
which are not morally sustainable to your fellow people. A lot concern of the common good can actually create the<br />
problem not be the solution , the challenge is to put back respon<strong>si</strong>bility which is part of human nature , the idea of<br />
being prudent , dreaming but not with other people’s money , and if it doesn’t work out you should bear full<br />
respon<strong>si</strong>bility.<br />
Fraud and dishonesty and also pressure from higher level on the lenders are part of what happened globally,<br />
the solution is to change the incentive there are trade-offs between trade and spirituality. People were allowed more<br />
than they should to spend other people’s money but the problem is that your just not as prudent and respon<strong>si</strong>ble if<br />
they are not your own.<br />
Conclu<strong>si</strong>ons<br />
119
We should con<strong>si</strong>der that if bu<strong>si</strong>nesses keep globalizing, we are going to gradually lose interest in developing<br />
and investing locally, we are going to sleep locally but think globally. A very strong humanity cri<strong>si</strong>s has got us were<br />
we are, greed is involved here .Gandhi had a very true statement universally valid, that the earth has enough<br />
resources to satisfy any need pos<strong>si</strong>ble but one and this is human greed.<br />
We are taking part of a over consumption of morality , of humanity and a immoral sub consumption of<br />
survival and those two are doing nothing but strengthening the cri<strong>si</strong>s , an organic economical growth meaning a<br />
healthy growth should be adopted because we should think of the economy as a living breathing organism .<br />
Globalization can not be escaped, because the revolution of means has made pos<strong>si</strong>ble for all production<br />
components and services to travel to fast, what some say is that the economy is heading to a revolution of<br />
expectations .We should learn to change, you can change your way of life and in consequence the results and the<br />
way we are making our existence but we can only achieve this by changing the way we think .If people don’t have<br />
the capacity to change , to innovate than companies and also societies will fail.<br />

Introduction<br />
It is impos<strong>si</strong>ble to know whether objectives of the competition policy are correctly set, whether the institutional<br />
structure and process are well defined and ultimately whether the actions of a competition authority produce the<br />
de<strong>si</strong>red outcome if the performance of the institutions is not measured in one way ore another. In some cases<br />
measuring these aspect turned out to be a difficult activity.<br />
Changes in the institutional, technological and economic environment and also the deepening of market integration<br />
raise new challenges for European competition policy. This context requires de<strong>si</strong>gning a modern ver<strong>si</strong>on of the<br />
competition policy which is able to promote not just a new competitive spirit as a way to an efficient allocation of<br />
resources, but more than that, a new institutional and legal competition system which makes markets work better.<br />
This new vi<strong>si</strong>on should be embraced both by public and private actors. This paper focuses on the meaning of<br />
efficiency for the competition policy from the authorities and the companies’ point of view u<strong>si</strong>ng quantitative and<br />
qualitative analyses. I will also make some proposals of testing if the new de<strong>si</strong>gned competition policy produce the<br />
de<strong>si</strong>red outcome and that requires measuring its performance as a proof of its efficiency.<br />
Measuring objectives<br />
Competition policy is not solely an economic policy; it has social as well as political implications (Motta, Mas<strong>si</strong>mo<br />
2004). Socially it means greater welfare for individuals. Politically it supports democracy by preventing concentrated<br />
economic power able to distort popular impulses. Today the main objectives of completion policy as enforced by the<br />
EC are most probably economic efficiency and European market integration.<br />
European competition policy has recently come to acknowledge that be<strong>si</strong>des market integration the enhancement of<br />
consumer welfare is the ultimate goal of the enforcement of competition rules. This recognition has taken place<br />
parallel to the decentralization of European competition law enforcement and the introduction of a more economics<br />
and effects based approach.<br />
Economic welfare is the standard concept used in economics to measure how well an industry performs(Motta,<br />
Mas<strong>si</strong>mo 2004). It is a measure witch aggregates the welfare (or surplus) of different groups in the economy. In each<br />
giving industry, welfare is given by total surplus that is the sum of consumer surplus and producer surplus.<br />
Consumer welfare is the aggregate measure of the surplus of all consumers. This concept of welfare should not only<br />
be interpreted in a static sense but also in its dynamic component. In other words, future welfare matters as well as<br />
current welfare.<br />
Competition authorities all around the world are becoming more conscious of the impact that competition policy and<br />
law enforcement has on consumers. They seem to be ever more anxious to declare and demonstrate the <strong>si</strong>gnificant<br />
role they play as enforcers of competition law in consumers’ economic life. The European Commis<strong>si</strong>on is no<br />
exception. Neelie Kroes formulated the competition policy message of her cabinet as the following, ‘Our aim is<br />
121
<strong>si</strong>mple: to protect competition in the market as a means of enhancing consumer welfare and ensuring an efficient<br />
allocation of resources’. Director General of DG Competition, Philip Lowe empha<strong>si</strong>zed that, ‘competition is not an<br />
end in itself, but an instrument de<strong>si</strong>gned to achieve a certain public interest objective, consumer welfare’.<br />
It is difficult to say whether competition authorities and courts favor in practice a consumer welfare or total welfare<br />
objective. In the EU, Article 81(3) allows any agreement, deci<strong>si</strong>on or concerted practice which contributes to<br />
improving the production or distribution of goods or to promoting technical or economic progress, while allowing<br />
consumers a fair share of the resulting benefit. Furthermore, Article 2.1 of the Merger Regulation accepts in principal<br />
an efficiency defense provided that it is to consumer’s advantages.<br />
The concept of consumer welfare should also be interpreted dynamically in the sense of the effects of any structure<br />
or conduct on price, choice, quality and innovation in the short and long term. Sometimes these effects are immediate<br />
and measurable but often the effects are difficult to quantify and the only way to protect consumer welfare in the<br />
longer term is by safeguarding the process or dynamic of competition on the market.<br />
Competition policy also has other goals than improving final consumers’ welfare and therefore final consumers<br />
cannot and should not become the sole focus of competition laws.<br />
The defense of small firms has often been one of the main reasons behind the adoption of competition laws. The<br />
favorable treatment of small firms is not necessarily in contrast with the objective of economic welfare if it is limited<br />
to protect in such firms from the abuse of larger enterprises, or giving them a small advantage to balance the<br />
financial and economic power of larger rivals. Artificially helping small firms to survive when they are not operating<br />
at an efficient scale of production is in contrast with economic welfare objectives. This would encourage inefficient<br />
allocation of resources and would contribute to keep high prices in the economy. The European Commis<strong>si</strong>on seems<br />
to have taken the view that small and medium <strong>si</strong>ze enterprises (SME) are more dynamic, more likely to innovate and<br />
more likely to create employment than large firms. This would be an additional argument to promote SMEs.<br />
However, the empirical evidence is quite ambiguous. It would seem difficult to state that small firms make a larger<br />
contribution to growth and innovation than large firms.<br />
As a conclu<strong>si</strong>on, it makes sense that the authorities do not use their scarce resources to monitor agreements and<br />
mergers which involve smaller firms, but there is little rationale behind a systematic use of competition policy<br />
towards helping SMEs. Smaller firms are often heart by the lake of proper infrastructure and imperfect markets. Such<br />
difficulties had better be dealt with by government interventions at the root of the problem, rather than instruments<br />
such as completion policy, whose purpose lies elsewhere. There is a risk of creating additional distortions in the<br />
competition sphere, while giving only a very imperfect answer to the source of the problems.<br />
Promotion of market integration is one of the key objectives of the EU completion policy. This is a political<br />
objective which is not necessarily con<strong>si</strong>stent with economic welfare. EU competition law de facto forbids price<br />
discrimination across national borders. There is no economic rationale for such a different treatment. A priori, it is<br />
difficult to say whether price discrimination has a po<strong>si</strong>tive or negative impact over welfare.<br />
Competition laws might also incorporate objectives such as fairness and equity, forcing firms to behave in a certain<br />
way both with respect to costumers and to rivals. In some cases a particular interpretation of the concept of fairness<br />
might collide with an economic welfare criterion. For example the politically sen<strong>si</strong>tive issue of small shopkeepers<br />
versus large supermarket chains. In many countries, concern is often voiced that the supermarket chains exploit their<br />
bigger volumes so as to have bargaining power and buy from manufacturers much more cheaply than small shops.<br />
This allows the former to sell at lower prices than the latter. As a result, small shops have economic difficulties and<br />
could be forced to close down. Some people would argue that this is unfair and that small shops should accordingly<br />
be protected. This claim might be justified just from the point of view of fairness. Certainly, such reasoning would be<br />
at odds with ba<strong>si</strong>c efficiency principles. Whenever there exist economies of scale in a market, larger firms will have<br />
lower costs and will be more competitive. Small firms which fail to reach the minimum efficient scale of production<br />
or distribution will have to either content themselves with lower profits or exit the market. This process of<br />
rationalization whereby only the most efficient firms will stay in the market is beneficial for a community as a<br />
whole, as it will bring market prices down to the benefit of consumers. Interfering in this process by limiting the<br />
ability to charge lower prices would damage welfare. However, that fairness and efficiency are not always in<br />
contradiction.<br />
Since market power decreased with the number of firms in the industry, one might be tempted to conclude that the<br />
larger the number of firms the higher the welfare. The trade-off between allocative and productive efficiency (a<br />
larger number of firms increases competition and drives prices downward but at the same time involves a loss in<br />
economies of scale) implies that a policy aimed at maximizing the number of firms in any given industry would be<br />
unsound. If an authority tried not just to guarantee that entry is pos<strong>si</strong>ble in an industry and that all firms compete on<br />
equal grounds, but also tried to use sub<strong>si</strong>dies or other industrial policy instruments to actively promote entry in an<br />
industry or to artificially prevent firms from existing, this would conflict with an economic welfare criterion.<br />
122
These con<strong>si</strong>derations should act as a warning that competition policy should be about defending competition and not<br />
about defending competitors, which are less efficient.<br />
While it is widely agreed that the purpose of competition policy is to protect competition, not competitors, there is<br />
less agreement on how to go about doing that. To determine whether dominant firms are harming competition,<br />
agencies in many countries use a primarily effects-based approach, focu<strong>si</strong>ng on the economic impact that conduct<br />
has on consumers and competition. Agencies in a number of other countries, such as Germany and Korea, use a more<br />
form-based approach that focuses on how conduct can be categorized (Dube, Cornelius 2008). Economic analy<strong>si</strong>s<br />
still plays an important role in those jurisdictions, and the form-based approach may provide greater legal certainty<br />
and faster resolutions than effects-based methods. Some commentators believe, however, that a <strong>si</strong>gnificant problem<br />
with form-based approaches is that the same type of conduct often can be either “normal competition” or “abu<strong>si</strong>ve<br />
competition”, depending on the circumstances. Focu<strong>si</strong>ng on the conduct’s economic effect, they argue, is essential to<br />
making an accurate determination of its true nature, and thus it is worthwhile even if it requires more time than a<br />
form-based approach. Otherwise, competition law enforcement might not be con<strong>si</strong>stently aligned with competition<br />
policy’s economic purpose.<br />
“Best Practice” toward competition policy<br />
There is a convergence in the views of economists, lawyers and various practitioners regarding the principal<br />
elements of the “best practice” toward maintaining and encouraging competition in an economy.<br />
Objectives. The principal objective of competition law should be to maintain and encourage competition in order to<br />
promote economic efficiency and consumer welfare. Making economic efficiency the principal objective of<br />
competition law supports con<strong>si</strong>stent application of policies and is more likely to limit lobbying by vested interests.<br />
In some countries, however, competition law has multiple goals under the rubric of “public interest,” including<br />
fairness, regional development or employment, and pluralism or diffu<strong>si</strong>on of economic power through promotion of<br />
small and medium-<strong>si</strong>ze bu<strong>si</strong>nesses. Multiple objectives invite lobbying by different stakeholders in the economy and<br />
can lead to incon<strong>si</strong>stent application of competition law, so that governments end up protecting some firms from<br />
competition. (Shyam Khemani, R. 1997)<br />
Measuring the impact of the competition policy It is important for the competition policy also to know if the<br />
process created the de<strong>si</strong>red effects and evaluate them in order to adapt the policy to the new economic environment<br />
and prepare it to face new challenges.<br />
Instruments All competition policy and enforcement system con<strong>si</strong>st of essentially two components: the legal<br />
instrument and the administrative structure and process through which the legal instrument are implemented.( Lowe,<br />
Philip 2008) These two components should be analyzed and de<strong>si</strong>gned interdependently in order to maximize their<br />
efficiency. Creating these instruments requires economic analy<strong>si</strong>s and market knowledge.<br />
Developing a competition culture It refers to awareness among both the public at large and economic actors of the<br />
rules of competition. One of the main roles of a competition authority is to inform the public of these rules, and this<br />
can be accomplished through advocacy efforts and an effective communications strategy. Competition refers<br />
specially to the “ability of the competition office to provide advice, influence and participate in government<br />
economic and regulatory policies in order to promote more competitive industry structure, firm behavior and market<br />
performance” (World Bank)<br />
Some proposals for Romania<br />
Few months before the EU acces<strong>si</strong>on a research on the Romanian bu<strong>si</strong>ness environment regarding the role of the<br />
Competition Policy and the role played by the Competition Council in regulating the mechanism on the free market<br />
by protecting honest competition pointed out that these issues were ignored by the companies in their making<br />
deci<strong>si</strong>on process.(Dima A, 2007) More than that, the research showed that most of the companies included in the<br />
sample weren’t aware of the anti competitive practices and about the importance of avoiding them.<br />
Now, after two years from our EU acces<strong>si</strong>on is maybe appropriate to analyze whether the <strong>si</strong>tuation is chanced and<br />
whether the Romanian economic agents take in con<strong>si</strong>deration the rules of fare competition enforced by the European<br />
legislation. This process would help to evaluate the impact of the European integration on the competitive behavior<br />
of the economic agent from Romania. Measuring performance and impact of the competition policy in Romania is as<br />
important as it is this issue at the EU level. Making markets work better for the benefit of consumers and bu<strong>si</strong>ness is<br />
the main objective of the competition policy that should be evaluated.<br />
This performance measurement should be made following three dimen<strong>si</strong>ons. (Lowe, Philip 2008) The first one is<br />
productivity, for measuring the efficiency of the Competition Council. It indicates whether this institution acts<br />
properly to accomplish the main objectives of the competition policy and this dimen<strong>si</strong>on requires comparing on a<br />
regular ba<strong>si</strong>s on the one hand workload and inputs with, on the other hand, outputs. The second dimen<strong>si</strong>on is the<br />
quality of the entire process of enforcement which influences the companies and citizens perception on the<br />
123
importance of the competition policy as an instrument to make markets work better. The last dimen<strong>si</strong>on is the impact<br />
of the deci<strong>si</strong>ons related to the competition policy on different economic agents (consumer, companies and public<br />
institution). All this actions are important for all economic agents in order to understand the capacity of the<br />
competition policy to improve the economic environment functioning. These objectives will be achieved by<br />
indentifying the actual perception of the economic agents on the competitive environment and on the role that the state<br />
is expected to have in regulating and interfering in this field and the relevant factors that influence the Romanian<br />
companies’ competitive behaviour.<br />
Conclu<strong>si</strong>ons<br />
The principal objective of competition policy should be to maintain and encourage competition in order to promote<br />
economic efficiency. Achieving this purpose requires a periodically measurement of its performance although in<br />
some cases this turned out to be difficult, especially when the objectives are ambiguously set without any instrument<br />
created for their evaluation. There is a clear lack of empirical and theoretical investigation, which could provide<br />
some guidance to policymakers in the de<strong>si</strong>gn of competition policy.<br />
In this context the economic agents’ perception on the competition policy becomes very important in order to<br />
evaluate how this policy influences their competitive behavior. For that it is necessary to develop a competition<br />
culture in the society which can guarantee the competitiveness of an economy. This involves persuading<br />
stakeholders, including politicians, officials, bu<strong>si</strong>ness groups, labour groups, regulators, academics and the press, of<br />
the merits of competition. Also we have to be fully aware of deepening of market integration which will bring new<br />
challenges which call for both external and internal reforms of European competition policy.<br />

Introduction<br />
The economic integration represents one of the concepts that lay at the ba<strong>si</strong>s of the European construction. The<br />
theoretical background for the economic and monetary integration is represented by the theory of optimum currency<br />
areas (OCA), which is based on Robert Mundell’s contribution (1961) and on the subsequent contributions of Mc<br />
Kinnon (1963), Kennen (1969) and others. The theory analyses the costs and benefits of the adoption of a <strong>si</strong>ngle<br />
currency, empha<strong>si</strong>zing the conditions that must be fulfilled by the participant economies in order to minimize these<br />
costs.<br />
According to the integration stages defined by Balassa (1961), the concept of economic integration corresponds to<br />
the economic union stage, which becomes practically functional starting with January 1 st 1999, under the name of<br />
Economic and Monetary Union (EMU). The Maastricht Treaty, which mentions EMU as a major objective and<br />
which lays down the conditions for its launch and implementation, states that only the countries which prove the<br />
fulfillment of a sustainable convergence can participate in the final stage of the Economic and Monetary Union. The<br />
treaty defines convergence through a series of criteria, known as the Maastricht Criteria.<br />
The economic literature in the last years has made an important distinction between the nominal convergence,<br />
as<strong>si</strong>milated with the fulfillment of the Maastricht criteria and the real convergence, a term with multiple senses,<br />
which defines the may in which the characteristics of the optimum currency area are fulfilled, or the convergence of<br />
real variables, such as GDP per capita, salaries, prices. The real convergence does not represent a criteria in itself for<br />
the entrance in the euro zone, however, it has a great importance for the evolution of an economy towards fulfilling<br />
the nominal convergence, as well as for the good functioning of the economy as part of the euro area.<br />
The present paper details the nominal convergence criteria and determines the extent to which Romania fulfills them<br />
at present. In order to better present Romania’s performances against these criteria, a comparative approach is used,<br />
by including the performance of other countries in the region.<br />
125
In order to complete the image of Romania’s performance towards the convergence to the euro area, the paper also<br />
presents the analy<strong>si</strong>s of the real convergence, measured by the GDP per capita, from the same comparative<br />
perspective with the countries in the region.<br />
1. Theoretical aspects<br />
The OCA theory has shown if and in what circumstances it is beneficial for two or more countries to adopt a<br />
common currency. The optimum currency area, according to Mundell (1961) represents a “set of regions where the<br />
migration tendency is big enough to ensure full employment when one of the regions experiences a shock”. Mc<br />
Kinnon (1963) added the degree of openness of the economy to the characteristics of an OCA, while Kenen (1969)<br />
has shown that production and consumption diver<strong>si</strong>fication can also represent a characteristic of an optimum<br />
currency area. More recently, Pelkmans (2003) has defined the optimum currency area in a <strong>si</strong>mpler way, as “that area<br />
for which the cost of giving up flexible exchange rates or the realignment option is lower than the benefits of a<br />
<strong>si</strong>ngle currency”. All authors define OCA as an area which exhibits certain conditions or criteria which make<br />
pos<strong>si</strong>ble to handle asymmetric shocks without resorting to the use of the exchange rate or to monetary policy<br />
instruments.<br />
Although it was the foundation for EMU and it has foreseen many of the challenges EMU had to face over time,<br />
several criticisms were brought to OCA theory. Among the main criticisms is the one referring to the fact that the<br />
theory does not con<strong>si</strong>der the dynamic and endogenous nature of the criteria for the creation of an OCA and the fact<br />
that it ignores their subsequent po<strong>si</strong>tive evolutions and effects. Therefore, from this perspective, EMU can be created<br />
without the fulfillment of all conditions; these conditions can be fulfilled at a later stage. This approach empha<strong>si</strong>zes<br />
the long term benefits and it is the approached which determined the EU policies regarding EMU.<br />
This way, the Maastricht Treaty defines the nominal convergence criteria, related to price stability, the convergence<br />
of long term interest rates, sound fiscal policy – budget deficit and public debt, and the stability of the exchange rate.<br />
The entrance of a new economy in EMU is formally evaluated on the ba<strong>si</strong>s of these criteria. However, the subsequent<br />
evolution of the euro area and of the new entered economies reflects the degree of real convergence between these<br />
economies. Therefore, indirectly, one country’s performance in the euro area depends on the real convergence,<br />
although it does not represent an entrance criterion in itself. On the other hand, reflecting the approach that long term<br />
benefits are essential, EU has developed a special policy with the purpose of increa<strong>si</strong>ng real convergence, the<br />
cohe<strong>si</strong>on policy, which intends to reduce economic gaps between countries and regions.<br />
The OCA theory evolved, under the impact of the theoretical contributions and of the EMU evolution, such that<br />
today it is con<strong>si</strong>dered that EMU, although not an OCA according to the criteria from the clas<strong>si</strong>c theory, represents a<br />
functional monetary area.<br />
The nominal convergence criteria, as defined by the Maastricht Treaty, are presented below.<br />
Price stability: The inflation from the member countries must not exceed with more than 1.5 percentage points the<br />
average inflation rate from the three countries with the smallest inflation. The calculation methodology is based on<br />
the annual average inflation rate.<br />
Convergence of interest rates: The long term interest rates must not exceed with more than 2 percentage points the<br />
average interest rates of the same three countries as those from the previous criterion. The indicator used for each<br />
county is the interest rate for ten years maturity bonds, according to the transactions from a liquid and functional<br />
market.<br />
The solid fiscal po<strong>si</strong>tion refers to the budget deficit of each country, which must not exceed 3% from that country’s<br />
GDP, and to the public debt, which must not exceed 60% of the GDP.<br />
.<br />
The exchange rate stability refers to the fulfillment of the normal fluctuation band of 15% represented by the<br />
exchange rate mechanism (ERM) for a period of at least two years before the entrance in the euro area, without the<br />
depreciation of the currency with respect to the currency of another member state.<br />
The literature regarding real convergence is based on the hypothe<strong>si</strong>s that poor countries or regions have a faster and<br />
more accelerated growth than the developed ones, in order to achieve their income and productivity levels (Vohra,<br />
126
1997). Most of the studies are concerned with the analy<strong>si</strong>s of the GDP per capita gaps between the old member<br />
countries of the EU and the newly entered, with results which support the hypothe<strong>si</strong>s mentioned above (Lein –<br />
Rupprecht, Leon Ledesma, Carolin Nerlich, 2007).<br />
The economic and monetary union became functional starting with January 1 st 1999, and the first euro coins were<br />
effectively in circulation starting with January 1 st 2002. The euro zone initially had 11 member countries, to which<br />
Greece joined din 2001. The EU enlargement from 2004 with other ten member countries led to the enlargement of<br />
the euro area a few years later, through the adoption of euro by Slovenia in 2007 and by Malta and Cyprus in 2008,<br />
such that today the euro area has 15 countries. Among the remaining countries from 2004, the most advanced in<br />
terms of euro adoption are the Baltic countries and Slovakia, who have already entered ERM: Estonia and Lithuania<br />
starting with 2004, and Latvia and Slovakia starting with 2005. Romania, as well as Czech Republic, Poland,<br />
Bulgaria and Hungary are, from a formal point of view, further from this road, <strong>si</strong>nce they have not expressed their<br />
intention to join the exchange rate mechanism. For Romania, the only <strong>si</strong>gnificant official po<strong>si</strong>tion is the opinion of<br />
the National Bank of Romania, according to which the country could adopt the euro in 2014. This opinion however,<br />
was expressed in 2005 when economic conditions were very different from those today.<br />
For the purpose of this paper, the countries already in ERM II will be named Group I, while the others will be named<br />
Group II. These countries will serve as a comparison for Romania’s performance, being the closest pos<strong>si</strong>ble in terms<br />
of economic conditions and structure of the economy.<br />
2. Nominal convergence analy<strong>si</strong>s<br />
The paper evaluates the fulfillment of the nominal convergence criteria based on Eurostat data for 1997 – 2008.<br />
Romania performance are compared with the two groups of countries defined above (Group I and Group II), which<br />
contain the countries entered in EU in 2004 and 2007 and which have not adopted the <strong>si</strong>ngle currency yet. The<br />
definition of the two groups takes into account the entrance in the exchange rate mechanism. As such, Group I<br />
contains Slovakia, Estonia, Latvia and Lithuania, countries which are part of ERM from 2004 -2005, while Group II<br />
contains Bulgaria, Czech Republic, Hungary and Poland, countries not part of ERM. The analy<strong>si</strong>s of the fulfillment<br />
of the nominal criteria does not takes into account the exchange rate stability, <strong>si</strong>nce the entrance in ERM depends on<br />
the deci<strong>si</strong>on from the authorities.<br />
Inflation rate criterion<br />
The reference value was calculated according to the definition in chapter 1, as sum of the average inflation rate from<br />
the three countries with the lowest inflation and the additional value of 1.5 percentage points. It can be seen from<br />
tables 1 and 2 that Romania has an inflation rate with 2.1%, respectively 3.8% higher than the reference value. Year<br />
2008, in which the effects of the economic cri<strong>si</strong>s were felt, lead to the increase in both the reference value and the<br />
inflation rate in Romania and the countries from Group I, the highest increases being registered by the Baltic states.<br />

The comparison with countries fro Group II (tables 3 and 4) shows that, under the influence of the effects of the<br />
economic cri<strong>si</strong>s, the hierarchies, as well as the performances regarding the inflation arte were changed in this group.<br />
Although in 2007 there was one country, Poland that met the inflation rate criterion, in 2008, all countries are<br />
<strong>si</strong>tuated under the reference value. Romania end up from the 3 rd place to the 4 th one in this group in 2008.<br />
127
Also, it can be noticed that Romania’s po<strong>si</strong>tion in Group I reflects a rather good performance in terms of inflation, as<br />
compared with the countries already in ERM II, which should be closer to the reference value, taking into account<br />
that the entrance in the mechanism precedes the adoption of euro.<br />

Interest rate criterion<br />
The reference value is calculated according to the definition in chapter 1, as sum of the additional 2% and the<br />
average interest rate from the three European countries with the best performance in terms of inflation.<br />
For the long term interest rate, it can be seen that the countries from Group I have a very good performance in 2007,<br />
all of them meeting the criterion (Table 5). Romania is <strong>si</strong>tuated at a quite big distance from the reference value and<br />
from the performances of the countries in Group I. In 2008, however (Table 6), despite a slight decrease of the<br />
reference value, the long term interest rate in Romania increases, the same evolution being observed for Group I<br />
countries.<br />

As compared with the countries in Group II (tables 7 and 8), Romania is either on the last or before the last place;<br />
there are three countries meeting the criteria – Czech Republic, Poland and Bulgaria, in 2007 as well as in 2008.<br />

Budget Deficit Criterion<br />
The budget deficit criteria is approached from a longer time perspective, in order to show the evolution during the<br />
period 1997 – 2008. It can be observed from Graph 1 that Romania had a deficit lower than 3% of GDP during 2002<br />
– 2—7, but this po<strong>si</strong>tive evolution was stopped in 2008, when the budget policies were not able to avoid the<br />
deepening of the deficit from 2.5% of GDP to 5.4% of GDP. The increa<strong>si</strong>ng tendency of the budget deficit over the<br />
limit of the convergence criteria is seen also for the other countries in Group I, with the exception of Slovakia, who<br />
managed to keep a budget deficit of approximately 2%.<br />

The evolution of the countries in Group II is more heterogeneous. While Bulgaria has a budget surplus, Hungary<br />
manages to record a smaller deficit in 2008, although over the limit of 3% of GDP. In 2008, the only countries in this<br />
Group which fulfill the criteria are Bulgaria and Czech Republic. Romania has the biggest increase of the deficit in<br />
2008, as compared to the countries in this Group. It can be therefore stated that, although the economic cri<strong>si</strong>s has<br />
affected all countries analyzed, the big increase in Romania’s deficit may be also a result of the bad administration of<br />
the fiscal policy.<br />

Public Debt Criterion<br />
Graph 3 presents the evolution of the public debt in all countries analyzed, for the period 1997 – 2008. This is the<br />
only criteria that Romania meets. It can be observed that the countries in Group I have very small values of this<br />
indicator, around 20-30% of GDP, while Hungary registers very high values, eing the only countries that exceeds the<br />
60% benchmark.<br />

3. Real convergence analy<strong>si</strong>s<br />
The real convergence is analyzed u<strong>si</strong>ng the most often used measure for the analy<strong>si</strong>s of economic disparities between<br />
countries, GDP per capita. Data is taken also from the Eurostat Database. The paper takes into con<strong>si</strong>deration the<br />
evolution of the countries analyzed in comparison with the EU 27 average. Therefore, 100% represents the EU 27<br />
average. Graph 4 shows that, in real convergence terms, Romania has either the last or before the last place, together<br />
with Bulgaria. Over the period of time analyzed (1999-2008). Starting with 2005, Romania has higher values than<br />
Bulgaria.<br />
It is important to mention that all countries analyzed evolved in the same way, towards a greater real convergence to<br />
the EU average. The best performing countries are Czech Republic, Hungary, Poland and Estonia.<br />

It is therefore easy to see that, if in the case of the nominal criteria the evolutions are heterogeneous and the<br />
performance of countries entered later in EU, like Romania and Bulgaria can get close or even exceed the<br />
performance of the countries entered in 2004, in the case of real convergence, the development differences are<br />
<strong>si</strong>gnificant. While Czech Republic reached in 2008 a GDP per capita of 80% of the EU average, Romania is still well<br />
below, at a level of 45%.<br />
Conclu<strong>si</strong>ons<br />
The analy<strong>si</strong>s of the fulfillment of the nominal convergence criteria shows that in 2007, Romania respected the fiscal<br />
criteria, but did not respect the inflation rate criteria and the stability of the long term interest rate. In 2008, however,<br />
due to the effects of the global economic cri<strong>si</strong>s, but also to bad fiscal policies, Romania respects only one of the 4<br />
criteria analyzed, the public debt. The inflation evolution is increa<strong>si</strong>ng in all countries analyzed, including the<br />
developed countries which compose the reference value, but the increase in Romanian inflation is <strong>si</strong>gnificant and<br />
makes the county get closer to the <strong>si</strong>tuation of the Baltic countries, which were strongly affected by the global cri<strong>si</strong>s.<br />
For the interest rate, the changes are not extremely high, but the distance to the reference value is <strong>si</strong>gnificant. The<br />
most important evolution, however, is the increase in the budget deficit to 5.4% of GDP, especially <strong>si</strong>nce the deficit<br />
was within the limits of the convergence criteria for a long period of time, from 2002 to 2007. According to the<br />
nominal criteria, Romania’s performance was lower in 2008. For the future strict budget policies are necessary, as<br />
well as efforts to decrease inflation, in order for Romania to be able to get closer to the nominal convergence criteria.<br />
In what the real convergence is concerned, Romania has a long way ahead, being a lot behind the economies in the<br />
region. The comparison of GDP per capita with the EU 27 average reveals the fact that Romania is less than halfway<br />
to the European average in terms of real convergence. This may mean that, although in the short run efforts can be<br />
made to get closer to the reference values for the nominal criteria, the real economy is still the one in need of solid<br />
reforms in order to be able to cope with the pressures and eventual shocks that may appear as an EMU member.<br />
The choice of the moment to enter in the euro area has to take into account the correlation between the nominal and<br />
real convergence, such that Romania will be able to benefit from the advantages of the statute of euro area member<br />
and to minimize the associated costs.<br />

Introduction<br />
The address of this theme is motivated by the important role of the prudential supervi<strong>si</strong>on in ensuring financial<br />
stability in Romania, con<strong>si</strong>dering the dominant role of banks in the entire national economy.At the same time,<br />
current economic conditions represents challenges that supervisors must respond through a continuous adaptation<br />
and improvement of the supervi<strong>si</strong>on activities<br />
In literature, prudential supravegerea is defined as a process by which the supervisory authority (often the Central<br />
Bank) ensures financial stability u<strong>si</strong>ng a wide range of instruments, of which the most used are presented below.<br />
Thus, regulated indications and limits represent banking prudential requirements established by the supervisory<br />
authority through acts and which concern the solvency, liquidity, maximum exposure to a <strong>si</strong>ngle borrower and the<br />
133
maximum aggregate exposure, exposure to persons in special relations with the bank, currency risk, clas<strong>si</strong>fication of<br />
assets, establishment and use of risk provi<strong>si</strong>ons.<br />
Rating systems are more complex instruments, used to assess credit institutions in order to identify, at an early stage,<br />
those institutions that are inefficient or show adverse trends and requests from the supervisory authority, increased<br />
attention.<br />
Advantages of these systems in prudential supervi<strong>si</strong>on is related to the delimitation of the effective institutions from<br />
those in difficulty and to the reporting of the need to take action by the supervisory authority, and their disadvantages<br />
refers to their inability to generate forecasts on the future evolution of a credit institution.<br />
Early warning systems are complementary instruments of rating systems, u<strong>si</strong>ng econometric models and attempting<br />
to provide clues about the credit institutions’ future problems, based on their current financial <strong>si</strong>tuations.<br />
They are sophisticated mathematical models that predicts the downgrading of the institution’s rating or its<br />
insolvency, u<strong>si</strong>ng, most often functions of logit / probit (..).<br />
Although these instruments are con<strong>si</strong>dered extremely objective and useful in supervi<strong>si</strong>on activity, complex early<br />
warning systems currently exists only in the U.S. and France, the difficulty of their elaboration coming from the<br />
absence of a sufficient number of “witness cases” (Bogza, Mihai, 2007, p. 68), on the ba<strong>si</strong>s of which to performe<br />
statistical analy<strong>si</strong>s. However, these systems have shown weaknesses in the current economic cri<strong>si</strong>s, failing to indicate<br />
the potential bankruptcies of credit institutions.<br />
Public and private credit registries are indirect instruments, whose role in prudential supervi<strong>si</strong>on refers to the<br />
pos<strong>si</strong>bility of monitoring and analy<strong>si</strong>s of necessary capital and provi<strong>si</strong>ons, the pos<strong>si</strong>bility to review developments in<br />
the credit market, in the quality of bank assets, also to the pos<strong>si</strong>bility of as<strong>si</strong>sting the validation of internal rating<br />
models, developed in order to implement the requirements of Basel II, and also to the pos<strong>si</strong>bility of developing and<br />
refining the banking regulations (Dardac and Moinescu, 2007, p. 30-31).<br />
Prudential supervi<strong>si</strong>on in cri<strong>si</strong>s conditions<br />
Compared to the supervi<strong>si</strong>on tools described above and enshrined in literature and in the practice of supervisors, în<br />
condiŃiile crizei economice actuale, one can see the emergence of mechanisms de<strong>si</strong>gned to increase the<br />
effectiveness of prudential supervi<strong>si</strong>on.<br />
The strengthening of cooperation<br />
Thus, be<strong>si</strong>des the empha<strong>si</strong>s on the need to respect the ba<strong>si</strong>c principles formulated by the Basel II(Wellink Nout,<br />
2009, p. 4), we witness a strengthening of cooperation between supervisors in the supervisory boards of the second<br />
(EBC) and third (CEBS) level.<br />
In this context, CEBS recommends that the authorities respon<strong>si</strong>ble for supervi<strong>si</strong>ng cross-border groups to coordinate<br />
their activities closely, by improving information exchange, and particularly in the colleges of supervisors, to better<br />
understand the liquidity risk profiles of groups and to avoid unnecessary duplication of requirements. (European<br />
Central Bank Opinion on 5 March 2009, EU Official Journal of 22.04.2009, p. 7).<br />
Regarding participation in the colleges of supervisors for cross-border supervi<strong>si</strong>on of banking groups, the ECB<br />
con<strong>si</strong>ders that the use of these colleges would improve cooperation, risk assessment on financial stability and<br />
coordination of cri<strong>si</strong>s management.<br />
Also, the ECB supports the clarification of obligations on the exchange of information between supervisory<br />
authorities, especially in emergency <strong>si</strong>tuations, including negative developments in financial markets (idem, p. 7 -8).<br />
In parallel with this cooperation in the colleges of supervisors CEBS supports the granting, in conditions of cri<strong>si</strong>s, of<br />
an increased role for the supervisory authorities of the host country, which are currently monitoring only the liquidity<br />
of the foreign branches.<br />
Given the above, one can see that the efficiency of cooperation was confirmed by the current economic cri<strong>si</strong>s and,<br />
moreover, is supported the need to strengthen it.<br />
Harmonization of reporting systems and supervisory practices<br />
Due to the financial markets growing dependencies, in Europe there was, even before the emergence of turbulence in<br />
financial markets, a consensus on the need to harmonize regulation and banking supervi<strong>si</strong>on.<br />
In the current economic conditions, there is more empha<strong>si</strong>s on the need for harmonization of reporting systems and<br />
supervisory practices.<br />
134
Thus, it is con<strong>si</strong>dered that regulatory differences may destabilize financial markets and may increase risks involved<br />
in activities carried abroad. There is also a risk that institutions operating across national borders may avoid<br />
prudential supervi<strong>si</strong>on.<br />
Given these issues at EU level have been standardized frameworks for prudential and financial reporting:<br />
- COREP is a standardized framework for prudential reporting, developed by the Commitee of European Banking<br />
Supervisors, which systematises reporting requirements for own funds, capital requirements for credit risk,<br />
operational risk and market risk. The advantages of introducing this instrument refers to the facilitation of<br />
information exchange between supervisors and to the reduction of regulatory costs for reporting institutions. In<br />
Romania it has been adopted <strong>si</strong>nce 2008 as the supervisory reporting system at the individual and consolidated level.<br />
- F<strong>IN</strong>REP is a standardized framework for financial reporting which ensures comparability of financial information<br />
reported. It contains a set of ba<strong>si</strong>c information (balance sheet, the profit and loss) and other information, depending<br />
on the deci<strong>si</strong>on of the supervisory authority. In Romania it is applied at the consolidated level, starting with the<br />
financial statements for 31.12.2006, and for the individual level <strong>si</strong>nce 2008 for credit institutions applying Basel II.<br />
Moreover, during the unfolding economic cri<strong>si</strong>s, CEBS has guided the national authorities to harmonize supervisory<br />
practices(CEBS Work Programme 2009, www.c-ebs.org), "Guidelines on the implementation of the supervisory<br />
process", în cadrul pilonului 2 al Acordului Basel II, developed by CEBS, being used as a main reference in<br />
prudential supervi<strong>si</strong>on.<br />
Under these guidelines, supervisors put an increased empha<strong>si</strong>s on the implementation, by credit institutions, of sound<br />
standards regarding assumed risks (especially the credit risk and liquidity risk), according to Basel II.<br />
The empha<strong>si</strong>s on liquidity risk management<br />
According to CEBS Interim Report on Liquidity Buffers & Survival Periods(CEBS, 2009, www. c-ebs.org),it is<br />
clearly evident, from the recent financial turmoil, that banks need to hold a liquidity buffer. The more liquidity risk a<br />
bank runs, the larger its buffer should be.<br />
CEBS thinks that the liquidity buffer is dependant on three dimen<strong>si</strong>ons, the severity and characteristics of the stress<br />
scenarios, the time horizon fixed as the survival period and the characteristics of the assets in the buffer.<br />
At the same time, it is shown that liquidity buffers are of utmost importance in time of stress, when an institution has<br />
an urgent need to raise liquidity within a short timeframe and normal funding sources are no longer available or do<br />
not provide enough liquidity. These buffers, composed of cash and other highly liquid unencumbered assets, should<br />
be sufficient to enable an institution to weather liquidity stress without requiring adjustments to its bu<strong>si</strong>ness model.<br />
All-encompas<strong>si</strong>ng solutions for managing liquidity risk does not exist, but there is more work addres<strong>si</strong>ng this<br />
problem and the importance of liquidity management is more often stressed.<br />
Mechanisms for early intervention<br />
To avoid an increase in past-due claims of the banks, due to credit risk materialization in cri<strong>si</strong>s conditions,<br />
supervisors took into account the adoption of measures to limit the granting of loans.<br />
In some cases, the intervention was to restrict certain lending institutions or only certain lending products, and also to<br />
impose capital increase.<br />
Measures to limit lending are applied by authorities, depending on the degree of vulnerability of each credit<br />
institution.<br />
Thus, when trends in past-due debts of borrowers are worrying, supervisors require institutions to change lending<br />
rules or even prohibit the granting of new credits.<br />
Moreover, the new supervisory structure predicted by the Lamfalussy report proposes the establishment at EU level,<br />
of an early warning system and a mechanism for early intervention for those entities that have problems or go<br />
bankrupt.<br />
According to the report, such a mechanism should be defined precisely, clearly and should be able to intervene<br />
quickly and to respect the rules on state aid in the EU.<br />
Until the creation of this mechanism, clas<strong>si</strong>c interventions of authorities, aimed at limiting loan, have proven<br />
effectiveness whereas they avoided the collapse of credit institutions.<br />
Increased transparency<br />
Basel Comitee respresentatives show that the current market turmoil require for increased transparency and suggests<br />
that reliable, clear financial information supported by quality audits are key elements in enhancing market<br />
135
confidence (Basel Committee on Banking Supervi<strong>si</strong>on, External audit quality and banking supervi<strong>si</strong>on, dec. 2008,<br />
www.bis.org)<br />
Although the legislative framework and regulations of the European Union in the field of prudential supervi<strong>si</strong>on<br />
include guidelines with explicit requirements of transparency provided by the two directives(Directive 2006/48/EC<br />
and Directive 2006/49/EC) and details regarding the implementation and compliance with legal provi<strong>si</strong>ons, CEBS<br />
in<strong>si</strong>sts, in response to economic cri<strong>si</strong>s, to increase transparency of the financial statements of credit institutions, the<br />
risks incurred and of the prudential supervi<strong>si</strong>on (Jochnick, 2009, p. 13)<br />
Risk assessment<br />
In asses<strong>si</strong>ng the risk profile of credit institutions, supervisors:<br />
1. follow the compliance with the principles of corporate governance;<br />
2. evaluate the stability, accuracy and efficiency of risk managemenet;<br />
3. follow the existence and effective functioning of specialized management support committees;<br />
4. follow the operation of an appropriate system of internal control and of a management reporting system<br />
transparent and efficient.<br />
The risk assessment based approach is a comprehen<strong>si</strong>ve and detailed evaluation of a banking institution's risk profile,<br />
which involves the sharing of bank or banking group in units of activity and units of support and then each unit is<br />
risk assessed.<br />
In the risk assessment, supervisors go beyond verification of the conditions and financial performance, asses<strong>si</strong>ng the<br />
effectiveness of written policies and procedures of the bank, planning and preparation of budgets, internal controls,<br />
information management systems and risk management systems. When these systems are inadequate, supervisors<br />
provide guidance to help the bank improve its systems and to improve thus the ability of risk measurement,<br />
management and control.<br />
Under conditions of economic cri<strong>si</strong>s, the periodicity of these assessments of risk profiles should be increased, in<br />
order to allow the identification of problems at an early stage and to take appropriate measures.<br />
Evaluation of illiquid assets<br />
In response to the <strong>si</strong>tuation of instability, the European Union authorities also stressed the importance of improving<br />
standards of evaluation, especially for illiquid assets (The Brussels European Council - Pre<strong>si</strong>dency Conclu<strong>si</strong>ons,<br />
www.con<strong>si</strong>lium.eu.in, 2009).<br />
Estimated fair value in inactive markets conditions is complex and subject to uncertainties, whereas the lack of liquid<br />
and active markets makes fair value subjective.<br />
Also, on a lowered market, fair value valuation may result in failure to meet the capital criteria and can have<br />
procyclical effects, in that it may accelerate the decrease in market by encouraging sales to meet the capital criteria<br />
(Gîrbină Maria Mădălina, 2009, p. 10).<br />
Given the difficulty of determining the fair value of assets on a market which is facing major problems, and effects<br />
that it can generate, the establishment of evaluation standards is a priority for CEBS, whereas the existence of<br />
uniform assessment practices will facilitate effective supervi<strong>si</strong>on of the quality of bank assets.<br />
Widening databases of credit registries and establishing bodies of guarantee<br />
Recent studies showed, even before the economic cri<strong>si</strong>s event, that the role of credit registries, as instruments of<br />
prudential supervi<strong>si</strong>on, should increase (Dardac şi Moinescu, 2007, p. 30-31). These can become a reference for<br />
validation and the control of internal ratings models of credit institutions, the main problem identified relating to the<br />
lack of access to borrowers solvency data (economic soundness, financial performance, the general characteristics of<br />
commercial morality and management capacity).<br />
Although many public and private records still do not include this information, after the the economic cri<strong>si</strong>s event,<br />
supervisors have supported broadening the database of credit registries, by including as reporting institutions other<br />
financial institutions than banks (in Romania, according to the provi<strong>si</strong>ons of Law no. 93/2009 on non-bank financial<br />
institutions, these entities will be reporting to CRB).<br />
However, with the aim of restoring confidence in supervised institutions, it was supported the establishment of<br />
abody for banking assets guarantee (RGF).<br />
Although these actions can not be regarded as direct instruments of prudential supervi<strong>si</strong>on, they help maintaining<br />
financial stability in periods of cri<strong>si</strong>s, facilitating the mis<strong>si</strong>on of prudential supervisors.<br />
136
Remuneration policies<br />
Exces<strong>si</strong>ve and imprudent risk-taking in the banking sector has led to the failure of individual financial institutions<br />
and systemic problems in Member States and globally. While the causes of such risk-taking are many and complex,<br />
there is agreement by supervisors and regulatory bodies, that inappropriate remuneration structures have been a<br />
contributory factor. Poorly de<strong>si</strong>gned remuneration policies that reward short-term profit and give incentives to take<br />
risks that exceed the general level of risk tolerated by the institution can undermine sound and effective risk<br />
management and exacerbate exces<strong>si</strong>ve risk-taking behaviour.<br />
Because poorly de<strong>si</strong>gned remuneration policies and incentive schemes are capable of increa<strong>si</strong>ng the risks to which<br />
credit institutions are exposed, competent authorities should impose measures regarding these policies. The European<br />
Commis<strong>si</strong>on thinks that those measures should include a requirement to hold additional own funds in appropriate<br />
cases (Public Consultation regarding pos<strong>si</strong>ble changes to the Capital Requirements Directive, 2009,<br />
http://ec.europa.eu). Competent authorities should also be able to impose financial or non-financial penalties on<br />
credit institutions and investment firms that have remuneration policies that are not con<strong>si</strong>stent with sound and<br />
effective risk management.<br />
These problemes are now discussed and may constitute amendments to Directive 2006/48/EC.<br />
Basel Committee's initiatives on cri<strong>si</strong>s conditions<br />
Basel Committee's initiatives reffering to present cri<strong>si</strong>s conditions are aimed at creating a more robust regulatory and<br />
supervisory framework and include:<br />
- better coverage of banks' risk exposures, including for trading book, securitisation, and derivative activities;<br />
- more and higher quality capital to back these exposures;<br />
- countercyclical capital buffers and provi<strong>si</strong>ons that can be built up in good times and drawn down in stress;<br />
- higher liquidity buffers;<br />
- stronger risk management and governance standards;<br />
- greater transparency about the risk in banks' portfolios.<br />
Also, in response to economic cri<strong>si</strong>s, the Basel Committee empha<strong>si</strong>sed the need to focus supervi<strong>si</strong>on not just at the<br />
micropudential level, on the soundness of individual banks, but towards a macroprudential approach, on broader<br />
financial stability objectives (Nout Wellink: Basel Committee initiatives in response to the financial cri<strong>si</strong>s,<br />
30.03.2009, www.bis.org).<br />
Thus, the current economic cri<strong>si</strong>s has revealed, be<strong>si</strong>des the need for a strong individual supervi<strong>si</strong>on ok banks, the<br />
need to allocate more resources for the purpose of understanding interactions between banks and those between<br />
banking and others financial sectors, this macro-prudential approach reducing systemic risk.<br />
Conclu<strong>si</strong>on<br />
Current instability highlighted the need to further strengthen the framework for financial stability by increa<strong>si</strong>ng<br />
prudential supervi<strong>si</strong>on and improving the tools used to manage to financial cri<strong>si</strong>s.<br />
At the same time, supervisors have been severely tested by this financial cri<strong>si</strong>s and the above shows that they have<br />
reacted quickly to new economic conditions, they quickly adapted their instruments and developed new forms of<br />
cooperation to protect financial stability.<br />
In this context, we should empha<strong>si</strong>ze the importance of supervisors’ independence and freedom in the choice of<br />
instruments.<br />

Introduction<br />
Inten<strong>si</strong>fy the pace of structural reforms in an expres<strong>si</strong>on which is often used in advisory notes of institutions like the<br />
IMF or the European Committee, especially in their dialog with emerging and tran<strong>si</strong>tion economies. The majority of<br />
scientific works give arguments according to which the structural economic reforms lay a solid base for long term<br />
economic development and socio-economic balance.<br />
Dăianu (2000, p. 132) notices that the postcommunist countries are faced with three great challenges in their<br />
transformation process:<br />
� Institutional establishment and modernization<br />
� Obtaining fast economic growth to catch – up with the developed countries<br />
� Ensuring social and political stability.<br />
These elements are tied with the level and dynamic of structural reforms, these reforms influence the economic<br />
<strong>si</strong>tuation (for example, the same author says that “the structural causes of inflation are tied to the insufficient<br />
restructuring of the economy” (Dăianu, 2002, p. 34)) and also the social, political and institutional context of a<br />
country.<br />
This paper analyses the dynamic of structural reforms in the EU countries which have not adopted the euro, before<br />
and after they became members.<br />
To measure the level of structural reforms, the Index of Economic Freedom provided by the Fraser Institute (2009,<br />
www.freetheworld.com) was used.<br />
The structure of this index is briefly shown in annex 1.<br />
Regrettably, the values of the index are only available between 2000 and 2006 (annual series), so the impact of<br />
becoming a member of the EU on structural reforms can be observed for only a brief period, only for the countries<br />
that joined the EU in 2005.<br />
At the same time, the impact of becoming a member of the EU on the economic context is analysed, with the help of<br />
indicators such as economic growth, inflation, the exchange rate, the government balance, the current account and<br />
the public debt.<br />
Finally, a <strong>si</strong>mple regres<strong>si</strong>on model is built, to study the connections between the level of reforms and the economic<br />
results of a country. The model indicates, most of the times, a strong and po<strong>si</strong>tive connection between the two<br />
variables.<br />
Preliminary observations<br />
In most of the countries that joined the EU in 2005, the index had a po<strong>si</strong>tive dynamic in the year they became<br />
members with reference to the previous year, some countries having important po<strong>si</strong>tive evolutions from this point of<br />
view (for example, Latvia improved it’s index by over 5,4% and reached the 42 nd place in the world ranking of the<br />
index at the end of 2005, after being the 50 th at the end of 2004, and Lithuania went from 42 nd to 27 th place, with an<br />
index increase of 6,45%.). The only exceptions are Hungary and Cyprus.<br />
The component analy<strong>si</strong>s indicates that the sub-indexes with po<strong>si</strong>tive dynamics in 2005 with reference to 2004 were<br />
for most of the countries: �£����and�¤�§¨©�£�����¢¤�£���©��¢©���§�£�¤��, while the sub-indexes<br />
somewhat surpri<strong>si</strong>ngly negative dynamics. The results are<br />
presented in Table 1.<br />

own calculations).<br />
(The calculations were performed in the following manner: for the countries that joined in 2005, the difference<br />
between the average of the values of an indicator in the two years after becoming a member, namely 2005 and 2006,<br />
and the average of the values of the indicator in the two years before becoming a member, namely 2003 and 2004<br />
was computed; for the countries that joined in 2007, the difference between the 2007 and the 2006 values of the<br />
index was computed.<br />
For the countries that adopted a certain form of targeting the exchange rate before or after becoming a member, no<br />
exchange rate volatility dynamic was computed).<br />
Generally speaking, the behavior of the new members is not the same. Still, a decrease in the exchange rate volatility<br />
can be seen, for all countries except Slovakia and Romania, and also an increased fiscal discipline, on the part of the<br />
central authorities. The government deficits decreased in all countries except Hungary, Slovakia and Romania, and<br />
Estonia and Bulgaria continued to have a government surplus.<br />
141
���¢©�£�, Most of the countries had a decrease of the except Hungary, Poland and Romania, still,<br />
only the first two have values of the ratio which come close (in the case of Hungary, they go over) the limit imposed<br />
by the Maastricht Criteria.<br />
(The values I referred to which are not in the tables were not included in the text for lack of space and are available<br />
upon request, or they can be found by consulting the indicated sources). �§�¨£��¤��<br />
The <strong>si</strong>mple regres<strong>si</strong>on model<br />
To verify the existence of a connection between the economic <strong>si</strong>tuation and structural reforms, a <strong>si</strong>mple regres<strong>si</strong>on<br />
model is presented, with the following equation: �¢<br />

1 (1)<br />
where:<br />
= 1 2<br />
I1 is the Macroeconomic Index computed as shown in annex 2.<br />
ILE is the Index of Economic Freedom.<br />
The model was estimated for the countries that joined the EU in 2005 and 2007, and also for two candidates, Croatia<br />
and Turkey, between 2000 and 2006 (the period for which values for the Index exist). Results are shown in table no.<br />

(Computations carried out in Excel)<br />
It can be seen that in 8 cases out of 14, there is a po<strong>si</strong>tive connection (the values of the slope coefficients are po<strong>si</strong>tive<br />
and statistically <strong>si</strong>gnificant) between the Index of Economic Freedom, con<strong>si</strong>dered a proxy for the level of structural<br />
reforms, and the I1 indicator, which describes the economic <strong>si</strong>tuation referring to economic growth, inflation and<br />
interest rate volatility.<br />
The limited number of observations indicates that one should be careful when interpreting the results of the model,<br />
still the regres<strong>si</strong>on hypothe<strong>si</strong>s verification tests give values that do not indicate the rejection of the model for being<br />
non – valid, as can be observed form table no. 4.<br />

Conclu<strong>si</strong>ons<br />
For most of the new members, the achievement of the objective of becoming a EU member did not trigger, at an<br />
overall level, a relaxation of the pace of the structural reforms, a pos<strong>si</strong>ble reason being their intent to adopt the euro.<br />
Still, the sub-indexes which correspond to the and areas<br />
have had, somewhat surpri<strong>si</strong>ngly, negative dynamics.<br />
As the short term impact of becoming a member on the main economic indicators is concerned, arguments for a<br />
<strong>si</strong>milar behavior of the new members cannot be supported, except when it comes to fiscal discipline and exchange<br />
rate volatility, which is to be expected, given the European laws which state a government deficit below 3% of the<br />
GDP, and the Maastricht Nominal Convergence Criteria. Economic growth, the current account and inflation have<br />
different dynamics in the analyzed countries.<br />
The economic evolutions can be con<strong>si</strong>dered po<strong>si</strong>tive in the majority of the new members.<br />
With the help of a <strong>si</strong>mple regres<strong>si</strong>on model, the existence of a connection between the value of the ������£��¢¤¤����computed by the Fraser Institute, con<strong>si</strong>dered a proxy for the structural reform level, and a<br />
compo<strong>si</strong>te index, based on the economic growth, average annual inflation rate and exchange rate volatility<br />
indicators. In spite of a very small number of observations (7, with 6 degrees of freedom), for 8 economies out of 14,<br />
statistically <strong>si</strong>gnificant slope coefficient values were obtained. All the coefficients are po<strong>si</strong>tive, and this indicates a<br />
po<strong>si</strong>tive correlation between the structural reform level of an economy, and the macroeconomic <strong>si</strong>tuation, as is<br />
described by economic growth, inflation and exchange rate evolution. ¦��¤��� �¢¤¤������¢©�¤¦��¤¢�©�£��©¨¨ ��¤ ���¤������§��<br />

The methodology of computing the index is shown in full on the web <strong>si</strong>te of the Fraser Institute.<br />
Annex 2: The methodology for computing the I1 Macroeconomic Index<br />
The macroeconomic Index I1 reflects the <strong>si</strong>tuation of an economy from the point of view of the benefits experienced<br />
by the firms and the households, and is based on three indicators, economic real growth, exchange rate volatility and<br />
annual average inflation rate.<br />
Computation steps:<br />
Step 1: A grade between 0 and 5 is given to each indicator, as follows:<br />
Economic growth:<br />
Interval 8%<br />
Grade 0 1 2 3 4 5<br />
Inflation rate<br />
Interval 30%<br />
Grade 3 5 4 3 2 1 0<br />
Modified coefficient of exchange rate volatility:<br />
Interval 0 0 - 1 1 - 2 2 - 3 3 - 4 4 - 5<br />
Grade 5 4 3 2 1 0<br />
The modified coefficient of exchange rate volatility was computed like this:<br />
a) The volatility of the exchange rate, expressed as n units of national currency / 1 unit euro, where the volatility =<br />
( − )<br />
∑ � =§�<br />
2<br />
=¡<br />
square mean deviationσ<br />
=<br />
1<br />
−1<br />
, where n is the number of observations. ¢£¤¥σ<br />
b) The modified coefficient of exchange rate volatility is computed, u<strong>si</strong>ng: ⋅100<br />
144
The modified coefficient was necessary because the square mean deviation is influenced by the <strong>si</strong>ze order of a series.<br />
Step 2: The index is computed, u<strong>si</strong>ng: �£ ¡� ¦¡�<br />
1 = 0,<br />
4 ⋅<br />

4 ⋅ + 0,<br />
2 ⋅<br />

_ ¥¦ ¡§¨ ©� ¦ ¡¨¦ ¦¨¦ � � � � £¤ ¡¢<br />
inf<br />
_<br />
Observation: The weights of the three indicators are not rigorously founded, which makes the index more intuitive<br />
and less scientific and rigorous. Still, it is con<strong>si</strong>dered that the usefulness of building this index is justified, because of<br />
the characteristics of the analy<strong>si</strong>s performed in this paper.<br />

The consolidation of the annual accounts for group organisations is requested by the international accounting<br />
standards – IAS 27 “Financial statements consolidated and not consolidated”. The purpose of the consolidation is to<br />
provide a true and fair view on the financial statements for group organisations.<br />
In order to be able to make a correct capital and dept analyses for an organisation, an analyst must collect a huge<br />
amount of information. The nature of this information depends by the analyst goal, but, generally speaking, those<br />
must includes information regarding the economy, activity domain but also the financial information for the<br />
company but also for the <strong>si</strong>milar companies. Most of the used information are available out<strong>si</strong>de the company –<br />
economic statistics, different analyses of the company activity sector, mass-media, data bases with information about<br />
the company and about <strong>si</strong>milar companies. We must not avoid the fact that the company provide also major<br />
information used in analyse, information available in the financial reports, press conference, internet official web<br />
<strong>si</strong>tes etc.<br />
Body work<br />
The mechanics for financial reporting in case of group companies is very important. The financial statements<br />
are the final product of a long and complicated process of operations, finances and investments accounting recording.<br />
The financial statements structures reflect the organisational system for a company. In order to be informed, any<br />
financial statements user must know the principles of their establishments.<br />
The company activities can be spited into operational, investments and financing. ��¤��¤¢©�£��©¨activities are those that are related to the current activities. For example, the food sales in case of a<br />
restaurant, services sales for a consulting companies, depo<strong>si</strong>ts taken and loans to the clients for a bank ��¤£��¤���¤��activities are those which are associated with the long assets buying. For example, purchase and sale<br />
of equipment by a restaurant, purchase and sale of an office building for a bank etc.<br />
146
�£�©��¤activities are those related to the acqui<strong>si</strong>tion or reimbursement of financial resources. The main fund source<br />
for this kind of operations is: chare holders and creditors. For example, issuing of new shares, engaging a loan or<br />
bond issue.<br />
Not every transactions are clas<strong>si</strong>fied a priori into one categories For example, the interest receive by a bank is a part<br />
of operational activities, because the main bank activities is depo<strong>si</strong>ts taken and loans to the clients. Oppo<strong>si</strong>te, the<br />
interest received by a restaurant for the bond that they hold (due to the temporary liquidity investments) is an<br />
investments operation.<br />
Activities of an organization are reflected in various elements: assets, liabilities, equity, income and expenses. Assets<br />
are economic resources of the company's debts are the creditors' financial claims on an organization, the equity claim<br />
is "re<strong>si</strong>dual" of the company, revenue is put economic resources for a company, means expenditure outflows of<br />
economic resources .<br />
The accounts include the accounts of the accounting records increases or decreases the items listed above. The<br />
financial statements are constructed u<strong>si</strong>ng these accounts. Financial <strong>si</strong>tuation of the organization is "drawn" on<br />
accounting accounts. The registration in the accounts is very important to provide an accurate picture of the<br />
organization's financial po<strong>si</strong>tion. The user’s purpose of financial statements is to take a picture more faithful to the<br />
"state" organization. Internal users are interested in this to take appropriate deci<strong>si</strong>ons on the operation of the<br />
organization. External users, on the other hand are interested to take a deci<strong>si</strong>on vis-à-vis the credit, financing,<br />
acqui<strong>si</strong>tion of shares, bonds, entering into bu<strong>si</strong>ness relations or various other reasons.<br />
To protect the external users in most countries there are regulations that oblige organizations to be audited by a firm<br />
of independent external audit (the obligation to change at a number of years the external audit firm).<br />
Moreover, OECD (Organization for Economic Cooperation and Development) issued principles of corporate<br />
governance that came to protect shareholders - particularly small shareholders, the meaning of the correct<br />
information.<br />
Internal users are also protected in the sense that they may be deliberately wrong information on the financial<br />
statements of organization. The external auditors provide a safe (but not absolute) that the financial statements are<br />
prepared in accordance with international accounting standards, or according to national accounting standards in<br />
force.<br />
To support internal users, come and internal auditors who audit powers over certain areas within the organization. An<br />
important role is also different rules for the protection of emerging information and management standards such as<br />
Sarbanes-Oxley.<br />
For a large-<strong>si</strong>zed organization, the proper recording and accounting management accounts is given by the equipment<br />
used and quality of experts who manage them. In large organizations, operations manuals are limited due to the<br />
number of operations that are managed. In the case of group, this <strong>si</strong>tuation is more complicated because of the huge<br />
volume of data to be processed in the accounting.<br />
In conclu<strong>si</strong>on, the available information in the accounts are processed so that the final amounts to get reflected in the<br />
financial statements described above. Often, external users of financial information have only the final information.<br />
Information intermediate balances of certain accounts, the financial po<strong>si</strong>tion of certain balance sheet items are<br />
available only to users of internal financial information. International accounting standards come to needs of internal<br />
and external users by setting the format and information contained in the financial statements.<br />
As noted above, corporate governance in the opinion of Diane K. Denis and John J. McConnell (Source: The Journal<br />
of Financial and Quantitative Analy<strong>si</strong>s, Vol 38, No. 1 (Mar. 2003), pp 1 - 36 published at the Univer<strong>si</strong>ty of<br />
Washington School of Bu<strong>si</strong>ness Administration) has two transmis<strong>si</strong>on mechanisms, one internal and one external.<br />
Regarding the internal mechanism of transmis<strong>si</strong>on, the main engine of transmis<strong>si</strong>on is represented by the Board of<br />
Directors. This is usually the interests of shareholders. The Management Board is to monitor and compensate<br />
management in order to maximize shareholder value. While in theory, the Board role is clear, in practice things are<br />
less clear. Often the Board of Directors includes some of the executives, but are cases when the Board of Directors is<br />
composed mainly of executives (which in theory should monitor them). Often the process by which members are<br />
appointed Board is such that management is often an important word to say.<br />
Shareholders is rarely not directly involved in the management of organizations and is rarely completely separate<br />
company. Typically, management has a few percent of the company. In this <strong>si</strong>tuation, the shareholders is an<br />
important element in terms of corporate governance. It is assumed that shareholders who are not involved in<br />
management, can influence the actions taken by management.<br />
In many countries, the government has many organizations. If you look at government as a <strong>si</strong>ngle entity, state<br />
corporations have a very concentrated shareholding. In recent years there has been a tendency to dispose of<br />
properties taken over by the state. Transfer of ownership from state to private supplies imported items that can be<br />
examined about the effect of ownership on firm performance.<br />
147
External mechanisms of corporate governance occurs in many forms. When the actual value of the company is very<br />
small compared to its potential value, there will be many parties interested in taking control of it. In this <strong>si</strong>tuation, it<br />
is most likely a change of ownership.<br />
Legal system is of particular importance in terms of external mechanisms of corporate governance. Jensen (1993)<br />
suggests that the legal system is an external mechanism of corporate governance but empha<strong>si</strong>ze that it has certain<br />
limits in solving issues that arise between managers and shareholders. La Porta, Lopez-de-Silanes, Shleifer and<br />
Vishny (1998) argue that the legal system has a fundamental mechanism in corporate governance. In particular, it<br />
stresses that the legal system in a country protects the rights of investors, so that it becomes the determining factor in<br />
the link between corporate finance and corporate governance in that country. Extend their research on various legal<br />
systems in several states. Comparing different systems of corporate governance is born but the question is the ideal?<br />
One is defined as the ideal? If any, are his characteristics? If there is one ideal that should be its characteristics?<br />
In principle, as stated Andrei Shleifer and Robert W. Vishny (A Survey of Corporate Governance, Andrei Shleifer<br />
and Robert W. Vishny, The Journal of Finance, Vol 52, No. 2, 1997, p. 737-783), corporate governance in managing<br />
the corporate donors to ensure that the value received in exchange for financing. How to ensure that shareholders but<br />
are rewarded? How to ensure that these managers do not "steal" the capital invested by shareholders? How do<br />
shareholders control managers?<br />
At first is not clear that shareholders receive in exchange for funding made by them (if they still receive something).<br />
Managers are remunerated by wages received. There have been cases in which managers of companies have "loot"<br />
companies. In Romania, the banking sector is eloquent in 90 years, when the rifle was more banks. Advanced market<br />
economies have solved this problem.<br />
Regardless of time and economy, issues of corporate governance râne an issue of major importance. As mentioned<br />
above, even in developed economies have a high disagreement on how good or bad corporate governance<br />
mechanisms are. There is an agreement between English models, Japanese, German or American. These mechanisms<br />
are very good, but there were few differences between them. Although not differ greatly from each other, from<br />
corporate governance systems in other states, there is a <strong>si</strong>gnificant difference. Literature refers to the italian system<br />
of corporate governance, which is con<strong>si</strong>dered insufficiently developed. In underdeveloped countries, including some<br />
in developing corporate governance mechanisms are mis<strong>si</strong>ng entirely. In Rus<strong>si</strong>a, the lack of corporate governance<br />
mechanisms has led to a series of problems in many privatized companies.<br />
Long-term market mechanisms helps corporate governance mechanism. The existence of market competition<br />
between companies will lead to minimizing costs, increa<strong>si</strong>ng efficiency and competitiveness, because otherwise<br />
would not be pos<strong>si</strong>ble to survive in a competitive environment. There are still some skepticism as to leave only to<br />
regulate the market and to support corporate governance mechanisms. The market can not provide certainty to<br />
shareholders and will recover the capital invested in the company. The existence of competition in the market make<br />
use of resources to be more effective and, available funds to be higher. Due to separation of duties, shareholders do<br />
not always have control over the company.<br />
Many authors, including Andrei Shleifer and Robert W. Vishny (A Survey of Corporate Governance, Andrei Shleifer<br />
and Robert W. Vishny, The Journal of Finance, Vol 52, No. 2, 1997, p. 748) raises the following question related of<br />
corporate governance: why shareholders put their money to the leadership, management, knowing that he has a great<br />
power of deci<strong>si</strong>on on how to use, until you lose one of them? The answer is somewhat obvious: shareholders expect<br />
to increase capital investment, to increase investment, high opportunity cost. Hopes that shareholders will have cashflow<br />
links future higher initial investment. These cash-flow <strong>si</strong>tes most often takes the form of dividends, but not<br />
only. The re<strong>si</strong>dual value, or value of sales is also very important and sought by shareholders. In the case of Romania,<br />
developments <strong>si</strong>nce 1989 have created the proper climate for starting and very rapid growth of many bu<strong>si</strong>nesses,<br />
which were then resold or be associated with larger international companies. If investors do not con<strong>si</strong>der that the<br />
re<strong>si</strong>dual value or resale along with cash flow can not cover future investment, they will not invest at the outset.<br />
Management, rewards often to show shareholders that their investment is profitable, attracting new funding sources<br />
from the various investors and financial markets.<br />
Another reason is that investors have when investing in a company without receiving any kind of control is that they<br />
are extremely optimistic. Investors are sometimes so enthu<strong>si</strong>astic that without investing too much to stand on and no<br />
thoughts to think about how they will recover their investment, only mizând evolution of the actions. An extreme<br />
ver<strong>si</strong>on of such behavior are Ponzi schemes, in which investors are attracted to repeatedly enter the last pay the<br />
original investors, thus creating the illu<strong>si</strong>on of a high yield. These pyramid schemes are studied in the literature,<br />
providing important information related to investor behavior and its information. These investors have no protection,<br />
just hope that they will recover the initial amounts and the yields expected. These pyramid schemes are very<br />
common in developing countries (Romania experienced several such schemes in the 90 - Caritas, Philadelphia, etc.).<br />
In Rus<strong>si</strong>a was famous MMM pyramid scheme in which millions of people have bought shares.<br />
148
In this context described above, it tried to limit the exaggerated optimism of investors, at least in some markets. For<br />
example, Kaplan and Stein in 1993 showed that high yields in government bonds were used to finance the take over<br />
in the United States in 80 years. Ritter (1991), Loughran, Ritter, and Rydqvist (1994), Pagano, Panetta, and Zingales<br />
(1995), Teoh, Welch, and Wong (1995) provide evidence which demonstrates that the initial and subsequent issue of<br />
shares are overvalued. It was noted that when the scholarship is very high have many issues of new shares, while the<br />
scholarship is reduced issuance of new shares are almost nonexistent. Similarly, when profitability is high companies<br />
held most issues new shares as opposed to periods of low profitability, they have very few issues of shares.<br />
The link between corporate governance mechanisms and mechanisms of financial reporting is very close. Financial<br />
reporting, especially in the group of companies is very important that shareholders interrnediul by taking "the pulse"<br />
of investment.<br />
There is a category of investors to finance the company in exchange for a certain control over the deci<strong>si</strong>ons that<br />
companies and assets. These funding agreements are based on legal grounds, so if managers violate these<br />
agreements, donors can address justice<br />
The most important as they have shareholders, is entitled to vote, which is particularly important especially when<br />
deciding mergers, acqui<strong>si</strong>tions, and the election board of directors (the board of directors), which can be controlled to<br />
some extent management (Mann (1965), Easterbrook and Fischel (1983)). Often, the right to vote is difficult to<br />
overview. In many countries can not vote by mail or fax, shareholders are required to be present at the appointed<br />
time and place to exercise their right to vote. In these circumstances, the right to vote by small shareholders becomes<br />
virtually impos<strong>si</strong>ble which assures major shareholders of non small shareholders vote.<br />
In Rus<strong>si</strong>a, there are organizations in which management threatened with firing employees shareholders, if not vote in<br />
a certain direction. It is more practical and neanunŃarea small annual meetings of shareholders, not to be present and<br />
to exercise such right to vote. Stalin said "it is not important how people vote, it is important who counts votes and<br />
generally include managers shareholder votes.<br />
Even if shareholders elect board of directors, this is not a guarantee that they represent their interests.<br />
An important role in terms of corporate governance has and Organization for Economic Cooperation and<br />
Development (OECD). Organization for Economic Cooperation and Development (OECD) is an international<br />
organization of those developed nations that accept the principles of representative democracy and free market<br />
economy. The organization has its origins in 1948, as the Organization for European Economic Co-operation<br />
(OEEC), the Organization for European Economic Cooperation to help manage the Marshall Plan reconstruction of<br />
Europe after the Second World War. Later the membership was extended to the out<strong>si</strong>de of Europe, and was reformed<br />
in 1961 after the Organization for Economic Co-operation and Development (OECD), in French: Organization of<br />
Coopération et de Développement Economiques.<br />
Organization for Economic Cooperation and Development is a unique forum where the governments of 30<br />
democracies work together to meet the challenges of economic, social, those related to globalization and exploitation<br />
of the opportunities of globalization.<br />
The organization provides a framework within which governments can compare their political experiences, seek<br />
answers to common problems, identify good practices and to coordinate domestic and international policies. This is a<br />
forum where the pressure can also act as a powerful incentive to improve policy and implementation tools that<br />
independent occa<strong>si</strong>onally can lead to the <strong>si</strong>gning of treaties.<br />
Exchanges of information and analy<strong>si</strong>s of OECD governments are provided with a secretariat in Paris. The<br />
secretariat collects data, monitors trends and analy<strong>si</strong>s and forecast economic developments. This research and social<br />
changes and bu<strong>si</strong>ness models developed, the environment, agriculture, technology, taxes and other areas.<br />
OECD helps governments to increase prosperity and fight poverty through economic growth, economic stability,<br />
trade and investment, technology, innovation, anteprenoriat and cooperation for development. There must be<br />
assurance that economic growth, social development and environmental protection are achieved together. Other<br />
goals include creating jobs for everyone, social equity, clean and effective governance.<br />
OECD works to understand and to help governments respond to new developments and concerns. These include<br />
trade and structural adjustment, online and security challenges of reducing poverty in the developed world. For more<br />
than 40 years, the OECD is one of the largest and most reliable sources of comparable statistical, economic statistics<br />
and social data. OECD databases include a wide and varied range, such as national accounts, economic indicators,<br />
labor, trade, occupation, migration, education, energy, health, industry, charges and taxes, and the environment. Most<br />
of the studies and analy<strong>si</strong>s are published.<br />
For over the last decade, the OECD has resolved a number of social, economic and environmental, and deep<br />
connection with bu<strong>si</strong>ness, trade unions and other civil society representatives. Negotiations at the OECD in respect<br />
of taxes and transfer pricing have opened the way of bilateral treaties around the world (source:<br />

Conclu<strong>si</strong>ons<br />
There is a generally accepted view (Andrei Shleifer and Robert W. Vishny (A Survey of Corporate Governance,<br />
Andrei Shleifer and Robert W. Vishny, The Journal of Finance, Vol 52, No. 2, 1997, p. 753), that when shareholders<br />
have odds are very small and many in number, their rights may be violated more ea<strong>si</strong>ly by participating companies.<br />
When shareholders are few in number and have <strong>si</strong>gnificant shares, usually, they exercise greater control over the<br />
organization.<br />
Whatever the case, the role of corporate governance is increased when there are effective financial reporting, able to<br />
provide an overview of the organization.<br />
However, when we are dealing with group companies, the <strong>si</strong>tuation is very much complicated. Various risk<br />
concealing information related to one or more companies within the group is very high and it is extremely difficult to<br />
ensure a correct picture to the whole group. Consolidation process, seen as part of the financial reporting becomes a<br />
major role. Existence of different tax rules in different countries working members of the group companies, further<br />
complicating the process of consolidation.<br />
Shareholders, financiers, investors and existing potential users of financial information in general and group<br />
companies in particular must be helped in the sense of protecting their "mi<strong>si</strong>nformation" coming from the<br />
management.<br />

1. Collaborative systems<br />
Collaborative systems represent an interdisciplinary field at the intersection of economy, science,<br />
management, and sociology. Collaboration involves organizations that have a common mis<strong>si</strong>on and join together to<br />
form a new structure. (Arba 2005)<br />
A collaborative system is the system in which many users or agents are engaged in a shared activity, often in<br />
distanced locations. In the large family of distributed applications, collaborative systems are distinguished by the<br />
fact that the agents work together to achieve a common goal and have a great need to interact with each other in<br />
the sense that they share information, change requests, etc. (Dobrican 2005)<br />

from bank branches and headquarter;<br />
• The staff from headquarter develop rules, procedures, circulars, on which employees from bank<br />
branches operate their activity;<br />
• From the customers’ perspective, each branch is a separate unit of the bank, but from the bank<br />

measures to prevent this <strong>si</strong>tuation, meaning that computers and servers on which are the databases are<br />
equipped with UPS, which allows them to operate in case of a fall in electricity and the telecommunications<br />
is ensured in parallel by fixed and mobile phones. �§�� ��¤¤�¤¢�<br />

When collaborative systems are used voluntarily, one of the key drivers to success is the manner in which<br />
users feel their experience with the system: if they like, if the system offers them what they expect from him, if they<br />
are able to communicate freely and naturally with other participants, if they wish to recommend it to others. (Ivan et<br />
all 2007)<br />
2. Quality characteristics of collaborative banking systems<br />
The most important quality characteristics of collaborative banking systems are as follows: ¡ ¡<br />
-<br />
-<br />
-<br />
-<br />
-<br />
In the banking system, the reliability of a bank, seen as a complex collaborative system, refers to the confidence � �©£��©£�©�£¨£� ¡ £��¤�¢£� ¡ ����¨¤�£� ��¢�©�£¨£� ¢¤¨£©�£¨£�<br />
that the customers have in the bank ability to work properly and normally in all conditions before established. A<br />
bank is reliable if it is sustainable over time. The reliability of a collaborative banking system assumes strict<br />
compliance with those principles, rules, standards and operating procedures of a bank to ensure the profits<br />
maximization for a long period of time.<br />
refers ��¢�©�£¨£�<br />
to the ability of a collaborative system to be transferred from one work environment to another.<br />
Portability for collaborative banking system aims:<br />
- ���¢£��¤����§�¤���, refers to the degree of standardization and recognition at international<br />
level of models for each printed document: external payment dispo<strong>si</strong>tion, payment order, payment sheet,<br />
etc.;<br />
- involves the transfer of a management model from a geographic area to<br />
another. Applying a different model of management at baseline performs restructuring of banks. This<br />
model can be new or adopted from other <strong>si</strong>milar collaborative systems;<br />
- ���¢��¤�§¢¤�, involves measuring the generality degree of the procedures developed in a bank<br />
and applying them in other banks or collaborative systems, depending on circumstances;<br />
- refers to employees transferring from one branch to another and from one geographical<br />
area to another area. This portability is the movement of staff where the bank is opening new branches;<br />
-<br />
��¢�©�£¨£�<br />
���¢��¤��¤�, refers to the pos<strong>si</strong>bility of carrying out operations in various other conditions of<br />
work than usual and by others;<br />
- is<br />
��¢�©�£¨£�<br />
the<br />
���©�©�¤�¤���<br />

A bank and the opens branches in different counties or cities in the country do an example of portable<br />
collaborative system.<br />
Figure 3. Portable collaborative system<br />
If the bank has its headquarters in the county of X, then opening a branch in the county of Y provides its presence<br />
in this county. This ensures portability of collaborative banking system. It con<strong>si</strong>ders the following variables:<br />
- = the total number of bank equipment;<br />
- ��= = the number of equipment that are portable;<br />
- the total number of bank employees;<br />

The collaborative banking system is a system with high complexity, with a large number of components and a<br />
large variety of links between them. The complexity of the banking system is given by the operations they carry<br />
out, but also by the collaboration between different banks from different countries and by the alignment to<br />
standards imposed by the regulations in this worldwide field. The collaborative banking system has components<br />
that can be represented by u<strong>si</strong>ng a graph, the nodes being represented by these components, and the arcs by the<br />
links between components. The aggregated complexity of the collaborative banking system, ��, is given by the<br />
complexity of the subsystems that form it, ���, and by the complexity of linkages between subsystems, ���, as<br />
follows: ��§¨©�����©���, ¨��§�and¨��������are where importance coefficients; (2)<br />
The characteristic of collaborative systems is well evidenced in the banking system, specifically in<br />
the case of commercial banks and its branches. Branches of banks are collaborative systems that fulfill a <strong>si</strong>ngle<br />
£��¤�¢£�<br />
154
function, namely, managing client accounts and transactions conducted by them. By integrating these branches result<br />
the large collaborative system, represented by the bank itself, which in this case fulfills many functions.<br />
The integration capacity of a collaborative system is given by the ratio between the value of integrated system<br />
and the expenditure, which is made to ensure the integration: ¤¢= , where: (3)<br />
¦is the integration capacity of a collaborative system; �¦�is the expenditure made to ensure the system integration;<br />
is the value of integrated system.<br />
If two banks merge by absorption, the absorbed bank must be integrated into the one who bought it, by<br />
determining it to function exactly as the parent bank. Because a sub<strong>si</strong>diary bank purchased to work after the ¡�¦ £¢¡ ¡¢<br />
parent bank rules, are made expenses for operators’ trainings, equipment, furniture, software and support,<br />
bu<strong>si</strong>ness changing and others.<br />
In this case, the integrity degree can be determined as follows:<br />
−<br />
= �¦�is , where: (4)<br />
the integrity degree;<br />
���represent the acqui<strong>si</strong>tion cost of the bank;<br />
represent the costs incurred to ensure integration.<br />
In the case of a commercial bank, regarded as a collaborative system, the refers �©£��©£�©�£¨£� �¢� ©�§<br />

primarily to<br />
maintain its information system. The banks information system is very complex and very clever, because it must<br />
manage client accounts. The bank existence to the market is limited in functionality and maintainability of its<br />
information system.<br />
3. Increa<strong>si</strong>ng the efficiency and the performance level in collaborative banking systems<br />
In the collaborative banking systems are the following components:<br />
- ��¤�©�¤¢£©¨, which includes buildings, equipment and other property;<br />
-<br />
, con<strong>si</strong>sts of flow of electricity, Internet and intranet connections, alternative channels of<br />
communication;<br />
- ��¤£���¢�©�£��, compri<strong>si</strong>ng all software and hardware resources available to the bank to conduct its<br />
bu<strong>si</strong>ness;<br />
- ��¤�§�©�, including the bank human resources, the categories of personnel and the qualification<br />
levels of them.<br />
��¤¤�¤¢�<br />
155
Bank's financial results depend largely on the quality of staff and the efforts of each employee separately. For<br />
each po<strong>si</strong>tion of the bank, the department of human resources is seeking people with a degree of training higher<br />
than required by the job in question. The goal of this recruitment is the elimination of cases in which an employee<br />
fails to meet certain requirements or to resolve certain issues related to its activity. Training of employees at work<br />
must be done at least every five years. During this period, an employee of the bank carries out one or more<br />
trainings.<br />
Regarding the collaborative banking system, an indicator for increa<strong>si</strong>ng the efficiency is the level of staff<br />
training. Con<strong>si</strong>dering the qualifications period of five years, the minimum number of qualifications that get an<br />
employee is one in five years and the maximum number is one per year or five qualifications over five years. The<br />
maximum number of training ses<strong>si</strong>ons that the bank will finance, over a period of five years, is calculated according<br />
to the relationship: ��§�©��, where: (5)<br />
is the total number of training or qualifications supported by the bank;<br />
is the numbers of people employed in the bank and which are eligible for training.<br />
The degree of increa<strong>si</strong>ng the level of staff training, GP, is determined according to the relationship: �� ��<br />
©¢= is ��<br />
, where: (6)<br />
the degree of increa<strong>si</strong>ng the level of staff training;<br />
is the number of persons qualified in the five years;<br />
is the total number of training or qualifications supported by the bank. �� ��<br />
If we take into account the duration of trainings, in the formulas for calculation of the indicators will appear<br />
another two variables:<br />
= minimum duration of training, expressed in calendaristic months;<br />
= maximum duration of training, expressed in calendaristic months.<br />
In this case, the total number of training ses<strong>si</strong>ons supported by the bank within five years, expressed in<br />
calendaristic months, is given by the relationship: ��§�©��©��©��(7)<br />
The degree of increa<strong>si</strong>ng the level of staff training will be determined with the same formula, with the<br />
difference that the number of persons qualified in five years is weighted with the duration of qualifications for each<br />
person. This indicator shows the <strong>si</strong>tuation in which is the collaborative banking system in terms of level of staff<br />
training and the quality of human resources.<br />
Collaborative systems should work better than other types of systems. This is achieved by: �¤�§�£����¤�£�¤¡©£�£��£�¨£�¤, - to settle and resolve a specific problem: this proposal applies to<br />
collaborative systems involving a large interaction with customers such as banks or stores. Sizes that<br />
characterize the process of waiting are: the average number of people waiting in line, the average holding<br />
time for a person, the average number of people served and the average serving time for a person. In the<br />
case of the collaborative banking system is added also the volume of money traded per unit time.<br />
For a bank were obtained the following experimental values of the mentioned indicators for a number of 10<br />

For the collaborative banking system is defined the indicator average amount of money traded by a person per<br />
unit time, according to the relationship: £¦¤¥¡= , where: (8)<br />
VMBTP is the average amount of money traded by a person per unit time;<br />
VBT is the total volume of money traded per unit time;<br />
NPS is the average number of people served.<br />
Depending on the values obtained for the indicators in table 2 is achieved the ranking of bank staff, according to<br />
performance achieved. For example, the ranking of broker acting on the exchange market is made after the<br />
annual amount of profit made by each broker individually.<br />
Is calculated an global indicator for the assessment of a bank officer based on the indicators in table 2, as follows:<br />

on the mobile, Internet Banking and other alternative<br />
channels of communication, in the case of the banking system. These operations involve a lesser interaction<br />
with bank staff, leading to a higher speed of performing transactions. Thus increase the number of people<br />
served by the collaborative system, and the number of people waiting in line tends to zero. The<br />
implementation of alternative channels of communication is costly for a bank, but the growth rate of profits<br />
obtained by the use of these services is upward; �¤���¨§��§©�£���, in order to increase the stability of collaborative system. A person in a<br />
certain po<strong>si</strong>tion in an institution has accumulated experience that gives a certain stability and safety in the<br />
workplace. The staff fluctuation in a bank leads to a decrease in system efficiency and reducing<br />
productivity. To reduce this fluctuation, the department of human resources within the bank has a very<br />
important role, it can contribute by stimulating and motivating employees; ����©������¤¡�¢£¤��£¢���¤��, in order to increase efficiency and reliability of the<br />
collaborative system.<br />
4. Conclu<strong>si</strong>ons<br />
The development of collaborative systems conduct to increase their complexity and the global character of<br />
the economy is de<strong>si</strong>gned to determine, also a global character for many of the collaborative systems. From the<br />
information point of view, to these global collaborative systems must correspond global performance indicators,<br />
procurement systems scratchy and data conver<strong>si</strong>on procedures, to transform heterogeneous information into<br />
homogeneous entries for aggregate indicators, defined in the metrics of collaborative systems. Based on these<br />
aggregated indicators should decide appropriate to the global level, intermediate level and the execution level of any<br />
collaborative system organized into hierarchical levels.<br />
A collaborative system creates a environment where people can work better together, can share information<br />
without the constraints of time and space, being characterized by three fundamental aspects: joint activities,<br />
sharing environment and way of interaction.<br />

A Service Oriented Architecture for Public Transport Optimization<br />

Abstract<br />
Car traffic is one of the most important sources of global pollution. An easy solution for the authorities to<br />
reduce the number of cars in big cities would be to convince as many people as pos<strong>si</strong>ble to use public transportation.<br />
Be<strong>si</strong>des numerous advantages, public transport has as a major disadvantage the difficulty of selecting an<br />
optimum transport route, determined by the complexity of the network. Taking into con<strong>si</strong>deration this aspect, the<br />
present paper suggests a solution for route generating within multi-modal public transport networks. Taking into<br />
account the fact that different users con<strong>si</strong>der different routes as optimum, this paper proposes the utilization of<br />
flexible restrictions along<strong>si</strong>de the clas<strong>si</strong>cal options (number of transfers, number of public transport means, walking<br />
distance, costs and total duration). Thus generating a route which reflects much better the users’ preferences will be<br />
pos<strong>si</strong>ble.<br />
In order to allow a greater flexibility, the proposed solution relies on a service-oriented architecture.<br />
Structuring the application in independent web services allows the implementation of the user interface, either under<br />
the form of a web application acces<strong>si</strong>ble from the browser, or under the form of a desktop application or under the<br />
form of an application for mobile terminals. The open implementation allows taking the information from external<br />
sources via web services, of the XML standard (Exten<strong>si</strong>ble Markup Language) or of the RSS standard (Really<br />
Simple Syndication). Thus be<strong>si</strong>des the information strictly connected to public transport, users can be presented<br />
information about the air pollution in different areas of the city, the weather forecast as well as geo-referenced<br />
information from sources such as Wikipedia and Flickr. The system can also be ea<strong>si</strong>ly utilized as a geo- referenced<br />
adverti<strong>si</strong>ng platform by displaying location based advertisements.<br />

Introduction:<br />
A frequent problem in the big cities is the very busy car traffic which hardens the flow and generates great<br />
amounts of polluting gases which accelerate the global warming process and irremediably affects both men’s health<br />
and the environment. Thus passenger transport is estimated to generate approximately 15% out of the whole amount<br />
of carbon dioxide annual emis<strong>si</strong>ons [1]. Be<strong>si</strong>des noxious gases, phonic pollution caused by traffic also represents an<br />
important issue.<br />
A pos<strong>si</strong>ble solution for the authorities to reduce the number of means of transport in big cities would be to<br />
convince as many people as pos<strong>si</strong>ble to use public transportation. On the average, for one <strong>si</strong>ngle person who gives up<br />
u<strong>si</strong>ng his personal car and chooses public transport there is a cutting down of 9 grams per day in the carbon dioxide<br />
emis<strong>si</strong>ons, respectively an approximate of 2177 grams annually [2]. Furthermore, other advantages include the<br />
decrease in phonic pollution, ease of traffic, the reduction of the necessary number of parking places, the reduction of<br />
the investments necessary for the construction of passages and tunnels destined to ease traffic, the cutting down of<br />
expenses on passenger transport.<br />
Along<strong>si</strong>de these benefits, the utilization of public transport also presents drawbacks such as the very<br />
complicated structure of the transport network which makes the choice of an optimum route difficult. The selection<br />
of the best route is more difficult when the exact location of the final destination (museum, restaurant, park, etc) is<br />
not known.<br />
159
Therefore, it is more than necessary to implement a system which would not only allow the generation of<br />
routes in multi-modal transport networks (subway, bus, tram, etc) but will also benefit from a base of objectives as<br />
large as pos<strong>si</strong>ble which could allow passengers the pos<strong>si</strong>bility of generating routes without previously knowing the<br />
location of the aimed objective. Moreover, taking into account the fact that the same route is not generally<br />
con<strong>si</strong>dered as optimum by different passengers, the system must include the users’ preferences as accurately as<br />
pos<strong>si</strong>ble.<br />
The majority of the existing systems do not have one or more of these conditions, which drastically limits their<br />
utility.<br />
The model of system proposed in this paper takes into account the elimination of all the drawbacks present in<br />
the current applications by utilizing an open architecture which allows acquiring information from multiple sources<br />
via web services, the XML standard (Exten<strong>si</strong>ble Markup Language) or of the RSS standard (Really Simple<br />
Syndication). Thus, the proposed system is an open one which can display geo-referenced information from a<br />
multitude of sources (information about the air pollution, the weather, from Wikipedia, etc). The system also offers<br />
support for multi-modal transport networks. The service oriented architecture makes the system acces<strong>si</strong>ble from a<br />
wide range of platforms and devices. Great care has been taken to display results and information in a convenient<br />
and suggestive manner. In order to include the users’ preferences as accurately as pos<strong>si</strong>ble, the implementation of a<br />
flexible restrictions mechanism has been opted for, be<strong>si</strong>des the usual fixed restrictions.<br />
The open architecture also allows an easy implementation of additional geo-referenced services including for<br />
example a location based adverti<strong>si</strong>ng service.<br />
2. Existing applications<br />
2.1. Transport for London<br />
The Transport for London application [3] is one of the most complex applications developed in order to<br />
generate routes in public transport networks. It offers a wide range of options inexistent in other applications of this<br />
type such as the options for persons with disabilities (the impos<strong>si</strong>bility of u<strong>si</strong>ng staircases, elevators, moving stairs).<br />
Among the disadvantages, there can be mentioned the relatively small number of objectives and the impos<strong>si</strong>bility of<br />
u<strong>si</strong>ng the application on mobile devices.<br />
2.2. Google Tran<strong>si</strong>t<br />
The Google Tran<strong>si</strong>t application [4] launched at the end of 2005 aims at offering the pos<strong>si</strong>bility of generating<br />
routes by u<strong>si</strong>ng public transport means in several cities from the United States of America as well as some cities in<br />
Europe and Japan. Among the applications under analy<strong>si</strong>s, this is the poorest in options, the latter being almost<br />
inexistent. It allows the route generation both by selecting from the map the departure-arrival points and by directly<br />
indicating the public transport stops.<br />
2.3. RATB<br />
The application made available for the users of RATB [5] offers the pos<strong>si</strong>bility of generating routes having the<br />
option of selecting the type of public transport means which we might wish to use. The route generation is pos<strong>si</strong>ble<br />
only by indicating the departure and the arrival station. The utilization is difficult because the departure and arrival<br />
points cannot be selected directly from the map. The application does not offer support for the generation of routes in<br />
multi-modal transport networks, the database used not being integrated with the Metrorex database. Another<br />
drawback is the impos<strong>si</strong>bility of u<strong>si</strong>ng this application on mobile terminals. Furthermore, it is not offered the<br />
pos<strong>si</strong>bility of selecting an objective as the final destination point.<br />
3. Service Oriented Architecture<br />
The proposed solution is based on a multi-level architecture (Fig. 1 Service Oriented Architecture) integrated<br />
with the usage of web services. A web service is defined [6] as being a software system de<strong>si</strong>gned to assure the hostto-host<br />
interaction described via WSDL (Web Services Description Language) which uses standardized network<br />
protocols like SOAP and HTTP. A web service is based on a collection of protocols and standards used for data<br />
exchange between applications and systems. The software applications written in different programming languages<br />
160
which run on different platforms can use the web services in order to exchange data via a network mainly<br />
represented by the Internet, in a manner somehow <strong>si</strong>milar to interprocess communication on a <strong>si</strong>ngle computer. The<br />
interoperability is due to the usage of adequate public standards.<br />
Such architecture combines the advantages of multilevel architectures with the advantages offered by the web<br />
services: interoperability, RESTful, loosely coupled. Given the fact that the system will have to cope with a high<br />
number of independent requirements from users, it is recommended to use a RESTful [7] working manner which<br />
may eliminate the neces<strong>si</strong>ty of keeping a permanent connection between clients and server, thus decrea<strong>si</strong>ng the use<br />
of resources per server. The use of web services allows a good system scalability and the components can be<br />
installed on different servers.<br />
Within the architecture, the greatest part of the system functionality is concentrated in the web service “Main<br />
Web Service” which includes the route generating algorithm, as well as the connections to the external data sources.<br />
The external data sources can be web services or XML or RSS processed data. The proposed system overtakes the<br />
maps used for route display by u<strong>si</strong>ng the Microsoft Virtual Earth [8] web service, whereas information concerning<br />
the weather or the level of air pollution is taken via XML and RSS.<br />
The main web service is directly appealed to by the web component, by the web service for the mobile devices<br />
and by the module which manages the requests/responses via SMS (Short Message Service).<br />
The mobile devices service is destined to prepare data for transmitting and displaying on devices with lower<br />
displaying and proces<strong>si</strong>ng capacities. This service achieves the compres<strong>si</strong>on of maps and other information conveyed<br />
in order to reduce as much as pos<strong>si</strong>ble the data volume which has to be transmitted to the mobile device. SMS<br />
Gateway is destined to interpret the SMS messages which contain route generation requests originating from clients<br />
and to transform the response sent by the main web service in SMS messages which can be transmitted via the<br />
mobile phones network.<br />
The use of service oriented architecture thus allows the modular implementation of the system concentrating<br />
the functionality in distinct web services which can be independently altered or used within other applications. The<br />
system can be ea<strong>si</strong>ly extended with new components or can ea<strong>si</strong>ly overtake data from additional sources.<br />
The flexibility offered by such a system is large, the clients being able to use the system via the web<strong>si</strong>te, the<br />
application for mobile terminals or the SMS messages.<br />
Fig. 1 Service Oriented Architecture<br />
The main web service can communicate with the geo-referenced adverti<strong>si</strong>ng system in order to display<br />
advertisements to the users depending on their current locations. For example, the adverti<strong>si</strong>ng service can use as<br />
parameters the client’s GPS coordinates, the de<strong>si</strong>red adverti<strong>si</strong>ng layout (text, image and text) and the maximum<br />
distance to the objective for which the advertisement would be displayed. The display of advertisements for<br />
objectives close to the user’s location increases the efficiency of the advertisement. At the same time, the<br />
advertisement becomes less annoying and even useful for the user of the application.<br />
The data related to routes, stations and objectives are stored via the spatial database<br />
which allows the easy calculation of distances as well as the determination of stations<br />
and objectives which exist in a certain area.<br />
4. Interface<br />
Con<strong>si</strong>dering the service oriented architecture, the implementation of applications<br />
which use the functionality exposed by the services can be ea<strong>si</strong>ly achieved in multiple<br />
Fig. 2 Mobile device ver<strong>si</strong>on<br />
161
programming languages, as well as for multiple platforms or operating systems. In order to demonstrate these<br />
aspects, an implementation of the application has been achieved under the form of a web<strong>si</strong>te (Fig. 3), a desktop<br />
application and a mobile devices application (Fig. 2).<br />
The implementation as a web<strong>si</strong>te has the advantage that the clients can use the application without having to<br />
install it previously. The implementation for mobile terminals allows its clients to generate routes whenever<br />
necessary, even if they do not have access to the computer. The identification of the client’s location in order to be<br />
used in the route generating process or for the display of close objectives can be achieved either via the GPS module<br />
if this one is incorporated or, if not, via the mobile phone network. In order to facilitate the usage, it is recommended<br />
to use a <strong>si</strong>milar interface in all the implementations.<br />
No matter the chosen variant, the users can visualize<br />
the public transport routes, with the pos<strong>si</strong>bility of selecting<br />
only a certain type of public transport, can visualize the<br />
categorized objectives as well as information taken from<br />
external sources via RSS or XML such as weather or the air<br />
pollution level. On the map, there can be displayed<br />
information related to objectives overtaken from Wikipedia<br />
[9] or other geo-referenced sources.<br />
In order to improve the performance, only the data<br />
related to the objectives or stations vi<strong>si</strong>ble on the map at the<br />
respective moment are included in the client application. This<br />
is achieved by determining the geographical coordinates<br />
corresponding to the corners of the displayed map and by<br />
comparing them with the geographical coordinates of the<br />
objectives and stations by u<strong>si</strong>ng the specific functionalities of<br />
the spatial databases.<br />
The route generation can be achieved by selecting the<br />
departure and arrival points directly from the map or by<br />
typing the name of a station or objective. The user can<br />
Fig. 3 Web Ver<strong>si</strong>on<br />
flexibly express his preference for one or several restrictions.<br />
The implementation of the flexible restrictions mechanism at<br />
the interface level was done u<strong>si</strong>ng sliders which allow the user to give a smaller or larger importance to a certain<br />
preference (Fig. 4). Along<strong>si</strong>de the flexible options, there are also available the clas<strong>si</strong>cal limitations to restrict the<br />
generation of routes to a <strong>si</strong>ngle type of means of transport or to impose the obligation of the existence of facilities for<br />
disabled persons on the generated route.<br />
The generated route is displayed both on the map and under the form of a list of stations. Be<strong>si</strong>des the station<br />
names, there are also displayed the means of<br />
transport that can be used, as well as the type<br />
of transport means. If the journey implies<br />
station transfer, this is also displayed.<br />
5. Conclu<strong>si</strong>ons<br />
Fig. 4 Route generating options<br />
The present paper proposes a way of implementing a system for facilitating the public transport by u<strong>si</strong>ng a<br />
service oriented architecture which enables the realization of an open system which can be ea<strong>si</strong>ly extended and<br />
improved with additional functionalities. Such a system provides multi-level advantages. Thus for the city<br />
inhabitants, the implementation of such a system will mean a faster and cheaper transport. For the local<br />
administration the system will offer the advantage of reducing the car traffic and the costs related to the development<br />
of the route network. The environmental-friendly aspects include the reduction of the air pollution, of the emis<strong>si</strong>ons<br />
which contribute to the global warming and the cutting down of the consumption of non-regenerating energetic<br />
resources.<br />
162
Pos<strong>si</strong>ble later developments include the implementation of a collaborative model which allows its users to<br />
propose, alter or add information for the objectives displayed on the map, as well as the implementation of a system<br />
of notifying the users, should traffic jams appear on the chosen route.<br />

1. Introduction<br />
In the present context, in which the sustainable growth has to be achieved in conditions of globalization,<br />
technological revolution, the shift to knowledge-based economy and the global economic cri<strong>si</strong>s, people need to<br />
evolve rapidly. This can be achieved only if every individual has the necessary competences to live and work in this<br />
new society: according to the European Council, every citizen has to be equipped with IT skills, foreign languages,<br />
technological culture, entrepreneurship and social skills. Since 2000, it is widely recognized that people are the most<br />
valuable resource for development and economic revival. Knowledge, skills and personal attitude of all those<br />
involved in work process have major impact on innovation, productivity growth and competitiveness, but also<br />
contribute to motivation, increased satisfaction and quality of work of those engaged in economic activities. A list of<br />
competences needed to live and work in today’s Europe was developed: communication in the mother tongue,<br />
communication in the foreign languages, mathematical competence and ba<strong>si</strong>c competences in science and<br />
technology, digital competence, interpersonal, intercultural and social competences and civic competence,<br />
entrepreneurship, cultural expres<strong>si</strong>on, learning to practice life-long learning. However, these ba<strong>si</strong>c competences must<br />
be supplemented by more specific ones, according to each field of activity. This paper supports the general idea that<br />
learning is the only way to develop necessary competences for the present society and even identifies a strategic tool<br />
to do this: e-learning.<br />

2. E-learning, as a Strategic Tool for Competences Development Process<br />
Many European voices concluded that the development of key competences to obtain the economic welfare<br />
and growth is pos<strong>si</strong>ble only through systematic and continuous learning: lifelong learning. The empha<strong>si</strong>s on<br />
education in current society is essential (Alvin Toffler said that “the illiterate of the 21st century will not be those<br />
who cannot read and write, but those who cannot learn, unlearn, and relearn”): there is an “unprecedented<br />
dissemination of knowledge to all citizens through new resources u<strong>si</strong>ng the Internet and e-books and u<strong>si</strong>ng the<br />
164
methods of learning through electronic devices (e-learning)” (Draganescu, 2001, pp.25). Technological boom placed<br />
e-learning in an important po<strong>si</strong>tion among today educational elements. It has flexibility, mobility and it offers much<br />
more information: all these makes it the perfect candidate to be used in the educational processes by the individuals<br />
who already employed and who must divide their time between the self-development and the application of what<br />
they have already known.<br />
3. Modern Methods of Knowledge Representation for Competences Oriented E-learning Services<br />
There isn’t a challenge anymore to build an e-learning system, but there is a big challenge to build an<br />
efficient e-learning system, which has to be adapted to a certain activity domain. This thing is pos<strong>si</strong>ble only knowing<br />
the features which define that domain and having access to what knowledge means in that domain. As<strong>si</strong>milation of<br />
knowledge leads to the acqui<strong>si</strong>tion of competences related to the domain. Competency is "... a fundamental<br />
characteristic of a person, which may include features, ability, intention, a set of knowledge, an aspect of self image<br />
or of a social role ..." (Boyatzis, 1982, pp. 43) Profes<strong>si</strong>onal skills are distinct dimen<strong>si</strong>ons of behavior relevant to<br />
profes<strong>si</strong>onal performance. The performance is affected by how ea<strong>si</strong>ly and efficiently a person supports his/her own<br />
necessary behaviors. Competencies can be described as a set of observable behaviors, knowledge, skills, interests<br />
and personality issues. In a profes<strong>si</strong>onal environment (bu<strong>si</strong>ness or institution), employees competences have to be<br />
measured, evaluated, paid. These competences can be developed only by an e-learning system build on a<br />
competences related framework.<br />
A competences oriented e-learning system uses a database which stocks the domain knowledge. This<br />
database can be ea<strong>si</strong>ly mapped to the domain ontology. For knowledge modeling in a more efficient way, it is<br />
recommended to map the knowledge to semantic networks, where each node represents a concept (a set of<br />
knowledge) from a specific domain. The concepts can be grouped according to their semantic meaning in other<br />
concept nodes or competence nodes. All nodes from the first level of the domain ontology are competences nodes.<br />
Between concepts, there are two types of relations (Fig. 1): hierarchical relationships and logical constraints defining<br />
the mandatory learning order of the concepts. Some examples are provided below:<br />
• between A-C, B-C concepts, there are hierarchical relations: if a person knows concept A and concept<br />
B, then he knows concept C also; if a person knows concept A, but he doesn’t know concept B, then,<br />
for sure, he doesn’t know C either;<br />
• between A-B concepts, there is a logical constraint relation, if concept B can’t be learnt unless concept<br />
A is known;<br />
Figure 1. Relations in Competences Oriented Semantic Networks<br />
For quantifying the concepts relations or indicating that a competence node can have a variable number of<br />
child nodes, according to certain well-established rules, the semantic net has to be converted to a concept space<br />
graph. As an example, current paper describes the modeling of project management concepts which are needed to<br />
start a project. According to SinPers platform (Bodea, 2007, pp. 1), 7 concepts are needed (Tabel 1).<br />

SinPers system con<strong>si</strong>ders 46 elements of competence according to the International Competence Baseline,<br />
ICB v3.0, the Competence Standard of the International Project Management Association (IPMA) (ICB, 2008, pp.<br />
7): �¤���£�©¨����¤�¤��£¤�of • delivering projects in a structured way, including the project management<br />
process;<br />
• ����¤��§©¨����¤�¤��£¤�in managing relations with projects within organisations, programmes and<br />
portfolios, based on the knowledge of project characteristics, projects in the organizational context, and<br />
project environment;<br />
• �¤�©�£�§¢©¨����¤�¤��£¤�for a po<strong>si</strong>tive, collective, and dynamic thrust in nurturing project<br />
management profes<strong>si</strong>onalism such as leadership, communication, results-orientation, ethics,<br />
negotiation, and so forth;<br />
Each of these competences has a set of concepts. There are 200 concepts as a whole. IPMA chose to define<br />
four levels of competences : ��¤�¤¨�¡At • this level, the individual has to have demonstrated successful use of the competence<br />
elements in the coordination of programmes and/or portfolios; guided programme and/or project<br />
managers in their development and in the use of the competence elements; been involved in<br />
implementing the competence elements or relevant methodology, techniques or tools in projects or<br />
programmes; and contributed to the development of the project manager’s profes<strong>si</strong>on by publishing<br />
articles or presenting papers on his experiences or by outlining new concepts; ��¤�¤¨�¡At • this level, the individual has to have demonstrated successful use of the competence<br />
elements in complex project <strong>si</strong>tuations. He/She has also guide (sub) project managers in their<br />
application and implementation of the competence;<br />
¦�<br />
��¤�¤¨�¡At • this level, the individual has to have demonstrated successful use of the competence<br />
element in project <strong>si</strong>tuations with limited complexity. He/she might need to be guided in the further<br />
development of the competence element; ��¤�¤¨�¡At • this level, only knowledge related to the competence element is assessed by written<br />
examination;<br />
The levels are progres<strong>si</strong>ve: for example, the knowledge of an individual having a certificate of B type must<br />
exceed the one of an individual having a certificate of type C. That’s why IPMA levels provide a suitable framework<br />
for developing career paths and organizational maturity models as well as for personnel development programmes of<br />
individuals, companies and other organizations. An e-learning system should provide news both to an A certificated<br />
person and to a person with a lower level of certification. Con<strong>si</strong>dering a <strong>si</strong>ngle semantic network for the project<br />
management domain, something or someone should indicate to the e-learning system what should be the common<br />
knowledge in interaction with each type of user. The only solution is parameterization of difficulty level or<br />
information coverage level. When modeling this solution, concept space graphs have to be used (Bodea şi Trandafir,<br />
2008). The semantic network for each competence can be ea<strong>si</strong>ly extracted from the domain ontology. Then, this is<br />
transformed to a concept space graph, by a<strong>si</strong>gning weights to all nodes and vertices. For all nodes, the semantic node<br />
weight is calculated taking into account the path weights from the graph (Hardas, 2006, pp.37). Formula (1) is used:<br />

The e-learning system will create proper content for each certificated person, according to the sub-graph<br />
having all nodes with higher semantic weight than the difficulty threshold parameter (λ). Each distinct competencelevel<br />
pair has a threshold parameter. For example, applying formula (1) for “Start-up” competence element - level<br />

“Start-up” competence element - level C, all the concepts related to the current competences have to be taught<br />
(ARP, DDP, DIP, DDO, PRO, CPR, EEP). (Table 2)<br />

Representing knowledge with concept space graphs allows e-learning system to provide personalized<br />
service, targeted to user needs. E-learning services aren’t oriented only to teaching, but also to testing, analyzing<br />
results, creating profiles and so on and so forth. Users may have different roles, depending on the service. For<br />
example, in a testing service, they can be either the examinees or the examiners.<br />
4. Approach to Competences Management Model<br />
Applicability of knowledge base construction is immediate in skills management systems, knowledge<br />
systems or certification systems owned by various profes<strong>si</strong>onal institutions. If all of these systems query a knowledge<br />
base that is refined through the use of semantic networks and concept space graphs, that will increase the competitive<br />
advantage of individuals / organizations who use this knowledge base.<br />
Any organization that wishes to maximize the collective competences should use a system or a<br />
methodology to manage individual profes<strong>si</strong>onal competence. The paper further describes a model for managing the<br />
profes<strong>si</strong>onal competences used in an IT company. The main actors (Fig. 3) of the process are:<br />
167
• knowledge base (KB), which reflects both the representation of project management knowledge<br />
ontology and the IT knowledge ontology (here, there is a mixed domain); the knowledge is seen,<br />
finally, u<strong>si</strong>ng a database;<br />
• employees whose profes<strong>si</strong>onal competences are stored in the knowledge base (EM);<br />
• employers (or those who take the deci<strong>si</strong>on of people distribution on projects), based on the proven<br />
competences(EMR);<br />
• the competences management system itself (CompMS), which is an IT application that queries, edits,<br />
adds, deletes competences in competences base, but also has functions for working with semantic<br />
networks;<br />
• the e - testing application (eTestTool) used periodically to update the theoretical competences of<br />
employees or for inserting in the competences base of a new employee; it is a tool to improve the firm<br />
collective competences and it is a quick indicator of the available individual competences;<br />
• the e - learning (eLearnTool) used by employees to develop necessary competences;<br />
Figura 3. Competences Management Process<br />
There are two e-learning services in competences management process: the e-testing application, which<br />
identifies the knowledge gaps and the eLearnTool component. The second one is charged by competences<br />
management system with the necessary information needed to be taught to a particular employee. The employer is<br />
the one who takes the deci<strong>si</strong>ons in this process.<br />
A typical flow of activities in the competences management model from Fig. 3 is described below: the<br />
employer (EMR) aims to test the competences of a certain employee, so he configures the eTestTool (e-testing<br />
application). The employee (EM) interacts with the eTestTool, which gives him the results of the tests. The same<br />
results go to the employer, too. The employer verifies the results and determines whether the employee needs the<br />
take a training course provided by the eLearnTool. If the employer decides for training, he sends this request to the<br />
CompMS, which prepares the proper content for the eLearnTool and fires up the training. After taking the courses<br />
offered by eLearnTool, the employee will be better prepared and will have a higher level of competence. Another<br />
request that can be launched by an employer is when he wants to find out all the available employees, who have a<br />
certain set of competences, suitable for a new project. CompMS is the one which can solve the employer request, by<br />
creating a semantic network for the newly required competences and then overlapping this new network with the<br />
domain semantic network. Algorithms for semantic computability are used in this case.<br />
5. Conclu<strong>si</strong>ons<br />
168
Competences development is a topic of major interest in the present context, being con<strong>si</strong>dered among the<br />
main factors of economic progress. Present paper identifies an effective way of managing the profes<strong>si</strong>onal<br />
competences. In the current context, management means creation, improvement and use of competences.<br />
Competences management is conditioned by the development of a knowledge base. The base can be ea<strong>si</strong>ly modeled<br />
with semantic networks and concept space graphs. The competences management process described in the paper can<br />
be optimized through the introduction of additional competences when identifying the available employees for a new<br />
project: employers should take into account the tacit competences, too. These competences can not be verified<br />
theoretically, but can be intuited from the employees’ experience, from their psychological profile or work behavior.<br />

1. Introduction<br />
The national and international software applications and services development triggered a<br />
large diver<strong>si</strong>ty – in both quantity and quality – of input data. Having so many datasets, their<br />
characteristics require special approaching, regarding their organization and handling. Catay and<br />
Diri analyzed the consequence of datasets dimen<strong>si</strong>on upon software errors (2009, pp.1040), while<br />
Cipollini and Kapetanios (2008, pp.130-134) explored a stochastic model of large datasets<br />
variance. Xie et al. (2008 pp.117-123) and Zhang and Bajaj (2009, pp.39-53) treated the issue of<br />
large datasets visualization, whereas Li and Jacob (2008, pp.910-924) studied the adaptive<br />
reduction of data. The approaching manner of large datasets and of their applications becomes a<br />
forefront problem, requiring a deepen research.<br />
The paper intends to offer a theoretical ba<strong>si</strong>s in founding very large datasets oriented software<br />
development and propose architecture for this sort of applications. The paper also explains each<br />
component and justifies the modular approach.<br />
2. Very Large Datasets<br />
High-technology development in current society, citizen oriented software proliferation,<br />
along with new IT laws issuance, lead to production of software that works with very large scale<br />
datasets:<br />
- telecommunication operators records data about each call or message sent or received through the network,<br />
and keeps the information for a <strong>si</strong>x-months period;<br />
170
- internet and e-mail providers record data for each IP address in their own administration, about vi<strong>si</strong>ted web<br />
pages, along with exact time of access, and also about every electronic message sent;<br />
- public administration keeps payment history for millions of citizens;<br />
- national providers of gas and electricity operate millions of bills annually;<br />
- on-line search engines integrate content management of billions of web<strong>si</strong>tes.<br />
These cases presume lots of users that wield very large numbers of data – 10 7 ~10 10 datasets –<br />
along with software applications that structure, control and operate the data.<br />
Due to the large quantities of datasets that has to be processed, the applications get specific<br />
properties and functions. The characteristics of applications working with very large datasets aim<br />
at:<br />
• datasets acqui<strong>si</strong>tion and building, depending on their input method: keyboard, scanning, photo/video/audio<br />
capture, sensor capture, satellite capture;<br />
• quality requirements for datasets; the very large scale increase the probability to register structural and/or<br />
functional incoherent data; acqui<strong>si</strong>tion and proces<strong>si</strong>ng systems cause a low level of homogenization and<br />
aggregation, so an improved, optimum management of the data quality it’s necessary, to ensure data<br />
transparency and security;<br />
• data storage and protection, that ensure data integrity during processes;<br />
• datasets administration operations – which implies data creation, actualization and deletion – along with<br />
maintenance operations – archiving, refreshing – have to be improved, in order to be able to process large<br />
inhomogeneous data in real time; the scanning, clas<strong>si</strong>fication and extraction of the data is executed by<br />
implementing specific algorithms, such as the reduction algorithm, studied by Li and Jacob (2008, pp.910-<br />
924);<br />
• u<strong>si</strong>ng flexible search keys, along with multi-criteria filters for easy selection;<br />
• statistic proces<strong>si</strong>ng of data that increases operation efficiency.<br />
Working with very large datasets also presumes a large variety of risks:<br />
• security risks – due to the big volume of input data in time unit, the multiple sources of data and different<br />
ways and standards of acqui<strong>si</strong>tion;<br />
• integrity risks – due to different data quality levels, datasets heterogeneity and different usage purposes;<br />
• administration risks – due to multiple clas<strong>si</strong>fication pos<strong>si</strong>bilities, large hardware/software resources needed<br />
for effective handling of datasets.<br />
The quality requirements of very large datasets – homogeneousness, completeness – as well<br />
as quality of the large datasets oriented software are fulfilled through structural approaching of<br />
software development and solid architecture deployment.<br />
3. Software Architecture<br />
Software architecture definitions emerged during the first stages of the complex software<br />
applications development, which required analy<strong>si</strong>s and de<strong>si</strong>gn. The large variety of approaching<br />
the software architecture concept led to the neces<strong>si</strong>ty of its standardization. The IEEE Standard<br />
cited in The Architecture Discipline web<strong>si</strong>te (2009, http://www.bredemeyer.com/definiti.htm)<br />
defines it as “the organizational structure of a system”. The UML 1.3 standard cited in the same<br />
source (2009, http://www.bredemeyer.com/definiti.htm) goes deeper by saying that the<br />
architecture “can be recur<strong>si</strong>vely decomposed into parts that interact through interfaces,<br />
relationships that connect parts, and constraints for assembling parts”. Bass, Clements and<br />
Kazman offers a conclu<strong>si</strong>ve definition (2003, pp.21): ”The software architecture of a program or<br />
computing system is the structure or structures of the system, which comprise software elements,<br />
the externally vi<strong>si</strong>ble properties of those elements, and the relationships among them.”<br />
According to the same source (2003, pp.26) the importance of the architecture is given by the<br />
following implications:<br />
• it represents a mean of communication between stakeholders; software architecture represents a common<br />
abstraction of a system, which everyone interested in the project uses as a ground of understanding,<br />
negotiation, agreement and communication;<br />
171
• it represents the first de<strong>si</strong>gn deci<strong>si</strong>ons; usually, this are the critical ones and are very important for<br />
development, use and maintenance; it also sets the system quality level by empha<strong>si</strong>zing the performance,<br />
security, scalability, usability and the other quality metrics; it allows costs and planning estimation in the<br />
development process;<br />
• it represents a transferable and reusable abstraction of a system; software production imparts common<br />
architectures, which allow finding elements that should be kept or that are working together.<br />
In the process of software architecture production, three main aspects pointed by The<br />
Architecture Discipline web<strong>si</strong>te need to be pursued (2009,<br />
http://www.bredemeyer.com/whatis.htm):<br />
• system decompo<strong>si</strong>tion in components, which can be both structural or architectural elements or subsystems<br />
or parts; the decompo<strong>si</strong>tion has to strive for performance development, flexibility, exten<strong>si</strong>bility and<br />
allowing future functionalities at reasonable changing costs;<br />
• the analy<strong>si</strong>s of inner elements; once the system is decomposed, we have to answer the following questions:<br />
o do we have all the required components? The system structure must ensure the required<br />
functionality and services; in the process of architecture de<strong>si</strong>gning we must keep an eye on the<br />
dynamic character of the system and on the hardware and software infrastructure;<br />
o do the parts fit together? The problems concerning interfaces and relations between parts must be<br />
solved from the very beginning; a good match re<strong>si</strong>des in the specific attributes of the systems;<br />
• cross-cutting concerns; the elements must meet both the functional and non-functional requirements; in<br />
conflict circumstances, the parts must be adjusted according with the final objectives of the system.<br />
4. Very Large Datasets Oriented Software Architecture Characteristics<br />
The very large datasets oriented software (VLDOS) – along with their specifications and<br />
requirements – requires a well-structured architecture, both phy<strong>si</strong>cally and logically. The risks in<br />
adopting an architecture that is incompatible with the datasets dimen<strong>si</strong>ons and particularities are<br />
represented by failure in achieving the expected functionality, jeopardizing the datasets integrity<br />
and authenticity, or getting inadequate results.<br />
In the process of building the VLDOS architecture, the following issues have to be taken into<br />
account:<br />
• distance operating is prevailing, the architecture must de<strong>si</strong>gned to support distributed (client-server)<br />
computing;<br />
• datasets are either centralized (databases, data warehouses), or scattered in different network places;<br />
• the quality of the datasets must be assured from the very acqui<strong>si</strong>tion; however, separated modules/units for<br />
testing the datasets quality and for their completion, are recommended;<br />
• the datasets management, for easy selection and proces<strong>si</strong>ng, includes analy<strong>si</strong>s, sorting and clusterizing<br />
algorithms;<br />
• the <strong>si</strong>ze of datasets and their large number endanger the quantity and the quality of the network traffic; this<br />
issue becomes a priority, due to the high importance of the communication between network points;<br />
• the computation speed must be optimized, because large scale datasets – up to 10 9 – proces<strong>si</strong>ng usually<br />
takes hours or even days;<br />
• the availability of application functionalities must be ensured in every network point.<br />
According to Catal and Diri (2009, pp. 1040-1058), the structure of a VLDOS is affected by the datasets<br />
dimen<strong>si</strong>ons, the chosen quality metrics and the selections techniques. Additionally, software components of the<br />
application differ on:<br />
• datasets nature: databases with records, specific object sets, multimedia file sets, document databases;<br />
• the aim of application – acqui<strong>si</strong>tion, storage, administration, homogenization, scanning/reading, use of the<br />
datasets;<br />
• functional and usage medium of the application – open, protected, closed medium;<br />
• software/hardware development framework.<br />
Con<strong>si</strong>dering the huge traffic of gathered and processed information, the architecture must allow the usage of the<br />
information for modeling and applying deci<strong>si</strong>ons at any level in an organization. The client-server approach helps<br />
fulfilling this aim, by:<br />
172
• assuring quick analy<strong>si</strong>s; the preparation and analy<strong>si</strong>s of the large datasets takes hours and even days on a<br />
desktop computer; by u<strong>si</strong>ng enterprise-level, server-grade hardware and software, the processes are<br />
distributed to the local users, dramatically down<strong>si</strong>zing the time and freeing desktop and network resources;<br />
• reducing the network traffic; individual users can severely disturb the performances of the whole network,<br />
con<strong>si</strong>dering the large datasets carried along the network, even if the demand broadband is limited; u<strong>si</strong>ng the<br />
analytical servers – with consecrated wider databases connections – leads to better, optimum performances,<br />
delivering only the results to the client;<br />
• centralizing the monitoring and control; sharing power of proces<strong>si</strong>ng with users is done by the monitoring<br />
(or element, as an interface for the client computers which manage the user interface, and<br />
displays the results;<br />
element, as software server which organizes the data access, the computation, analy<strong>si</strong>s and export<br />
processes.<br />
and control facilities specific to the server products.<br />
The approach of the client/server architecture for VLDOS implies structuring them in two<br />
components:<br />
• ¨��©¨) element £¡¢-¤¡£ �¢����¤��<br />
• �©�£�¤��<br />
The does not directly use data, reducing the network traffic between the<br />
two elements and u<strong>si</strong>ng the calculation server. This way, the application can run in two different<br />
ways: local (fig.nr.1) and server (or distributed) (fig.nr.2). ¥<br />

The communication between VLDOS client and server is made u<strong>si</strong>ng the industry-standard TCP/IP protocol;<br />
when the client is connecting to the server, the user must mention the server name (or the IP address), the port<br />
number to which is connecting, the user name whose account must already exist on server, and the password<br />
associated with the user name. �£��¢£�§�¤�¡���� �£�����¤¢�¤¢<br />
5. A Pos<strong>si</strong>ble Architecture<br />
The framed Server VLDOS architecture includes two main components:<br />
- the data collection itself or the very large database<br />
- specialized modules/units for:<br />
o data acqui<strong>si</strong>tion;<br />
o datasets homogenization;<br />
o datasets clas<strong>si</strong>fication;<br />
o datasets selection;<br />
o datasets sorting;<br />
o datasets clusterization;<br />
o datasets export;<br />
The communication and data-flow diagrams are illustrated in fig.nr.3:<br />

The data collection refers but does not resume to: database, text/xml/multimedia files<br />
collection, data warehouse or any combinations of these. The collection administration requires<br />
specialized tools which unifies the software and hardware solutions for this type of data.<br />
The proces<strong>si</strong>ng units are respon<strong>si</strong>ble for datasets manipulation and refer to:<br />
- data acqui<strong>si</strong>tion; execution is done depending on the input data that might be:<br />
o <strong>si</strong>ngle text files;<br />
o xml files;<br />
o database records;<br />
o entire databases;<br />
The acqui<strong>si</strong>tion unit takes the data transmis<strong>si</strong>on demand from the client and asks for the<br />
input data format. After specifying the format, the unit suggests a standard template for<br />
data structure. The template can be modified first and then accepted and applied for each<br />
dataset. In order to minimize network traffic between server and clients, data acqui<strong>si</strong>tion<br />
should be centralized and executed directly on the application server. Before sending the<br />
data to its proper collection, the homogenization unit takes over.<br />
- data homogenization; while gathering the data, despite the nature of the data, its structure or even its manner<br />
of acqui<strong>si</strong>tion, it will always exist a percent of qualitative improper datasets: incomplete record<br />
attributes/fields, wrong tags, abnormal values or information impos<strong>si</strong>ble to render; the causes for these<br />
incoherencies can be:<br />
o input human errors;<br />
¡¢£¤¥¦¤¡¤<br />
o incomplete data transmis<strong>si</strong>on;<br />
§¨§ �©¡¢¤�¢� ¤£¥�¤ �¤ �����<br />
o natural disasters/accidents;<br />
o broken sensors;<br />
In order to apply data clusterization algorithms for speeding selection processes, the data need to be<br />
structural and functional homogenized. The first step is completed by the data acqui<strong>si</strong>tion module/unit<br />
175
which ensures the same structure for all input datasets. Before entering the collection, the validation<br />
executes:<br />
o filling incomplete fields with:<br />
� default values;<br />
� last records average – in proper cases;<br />
o framing numerical values in pre-set ranges;<br />
o verifying fields/attributes with pre-set format – e.g. e-mail address, P<strong>IN</strong>;<br />
o par<strong>si</strong>ng multimedia files and <strong>si</strong>gnaling errors;<br />
o handling files depending on their exten<strong>si</strong>on;<br />
o adding VLDOS special fields/attributes/tags for later interpretation;<br />
The application integrates automated methods of handling errors. If a certain error<br />
per<strong>si</strong>sts, the user is instantly asked about the problem value or warned about the<br />
incoherent dataset.<br />
- dataset sorting and clusterization; in order to optimize the selection process, sorting and clusterization<br />
algorithms are implemented over the entire data collection; the objective of clusterization is forming<br />
phy<strong>si</strong>cal or/and logical zones called clusters in which the datasets are structurally or functionally <strong>si</strong>milar; the<br />
degree of <strong>si</strong>milarity is given by the distance between datasets, which can be interpreted in many ways and<br />
can be computed in different forms; the applied clusterization algorithm depends on the data format and<br />
functionality:<br />
o K-means algorithm;<br />
o fuzzy algorithm;<br />
o QT algorithm;<br />
o graphs algorithm;<br />
Sorting is run within a cluster having a certain pre-set or given criterion. The sorting unit is automated for<br />
optimizing selecting time.<br />
- dataset selection; the unit/module takes the client/user data demand and searches within collection; the<br />
effects of all the other proces<strong>si</strong>ng units are clearly vi<strong>si</strong>ble at this level, when every set is:<br />
o structural and functional complete;<br />
o attached to a proper data collection;<br />
o assembled in a well defined cluster;<br />
o po<strong>si</strong>tioned within the cluster depending on its values;<br />
In these circumstances, selection means running through the structural layers step by step and not covering<br />
the entire collection.<br />
- dataset export; once found, the datasets are exported to the user for display or firstly operated on the server;<br />
the export process needs to take into account:<br />
o the original data demand;<br />
o the de<strong>si</strong>red return format;<br />
o the transmis<strong>si</strong>on security;<br />
- user interface; the details of the user interface depends on the application objectives, but it needs to fulfill<br />
two main functionalities:<br />
o datasets input;<br />
o dataset selection and return;<br />
The interface calls all the other units/components and transmits the proper proces<strong>si</strong>ng parameters.<br />
- collection interface; in the bidirectional way of data circulation the collection interface ensures on one hand<br />
datasets hoarding and on the other hand datasets access as explicit dataset demand from the user;<br />
Communication between units is done on the software level – by calling code,<br />
transmitting parameters and handling demands – as well as on the hardware – the existing<br />
network, u<strong>si</strong>ng proper protocols.<br />
176
6. Conclu<strong>si</strong>ons<br />
Appearance and proliferation of the large-datasets oriented software demands a new<br />
approach based on their unique proprieties. Software architecture in this case needs to be<br />
distributed and divided into units/modules so that data dimen<strong>si</strong>on would not impact the<br />
proces<strong>si</strong>ng time, but keeping correct output. The proposed architecture defines the general<br />
level, representing a frame, not more than a starting point, other details having to be specified<br />
depending on the specific objectives of the application that implements the processed model.<br />

During the present economic context, banks are becoming more and more precautious regarding their activity<br />
of granting credits. The credit requesting client’s profile analisys is more and more riguros and is time consuming.<br />
These facts were proved by an analisys realized by the Romanian National Bank.<br />
An evaluation of the indicators concerning credit institutions computed by the National Bank of Romania<br />
(BNR) brings to attention the fact that the percentage of defaulted credits as part of the total amount of existing<br />
credits at national level has clearly increased during the last quarter of 2008. If the percentage of “bad” credits was<br />
0.24 in September 2008 (at the end of the third quarter in 2008 when the effects of the economic cri<strong>si</strong>s were not<br />
perceived yet), the percentage increased at 0.35 at the end of 2008. This increase of 0.11 percentage points is a big<br />
increase if we take into account the relative stability of this indicator’s values during the previous 4 quarters (0.22,<br />
0.21, 0.30 and 0.24). �©�¨¤���¤¤��¨§�£�����¤�©§¨�¤��¢¤�£�����¢¤�£�£���£�§�£�����¤¢����<br />

*) Indicators are computed based on the provi<strong>si</strong>ons data reported by credit institutions<br />
NB: Indicators refer to all the credit institutions in Romania, including commercial banks, foreign banks branches,<br />
Creditcoop.Starting from January 1, 2008, indicators are computed based on the financial reports F<strong>IN</strong>REP and<br />
COREP of credit institutions. Source: National Bank of Romania (Banca NaŃională a României)<br />
These results confirm the general expectations that the repayment ability of credit customers would decrease<br />
during reces<strong>si</strong>on. This feature is one of the first indicators of the economic reces<strong>si</strong>on.<br />
Another observation that has to be taken into account when predictions referring to the economic evolution<br />
are being made, refers to the gross value of granted credits. This value is still higher than the total value of depo<strong>si</strong>ts<br />
as the percentage of credits related to depo<strong>si</strong>ts is 122% (we can notice a small decrease in comparison to the third<br />
quarter of 2008: 124.71%).<br />
Many analysts talk about the need of increa<strong>si</strong>ng the amount of liquidities of every financial institution during<br />
the cri<strong>si</strong>s. As a result of this need, banks and credit institutions offer a series of offers for depo<strong>si</strong>ts and they reduced<br />
the level o credits.<br />
By taking into account these observations, we can depict the importance of implementing risk evaluation<br />
applications in the credit activity. Starting from this assumption, it is very important for a client to evaluate his<br />
chances of obtaining a credit by taking into account bank’s requirements and his characteristics. Moreover, this<br />
application is important for the fact that it reduces the useless time spent for analyzing various banks’ offers and their<br />
evaluation forms. Furthermore the client is provided with guidance for obtaining a credit.<br />
The purpose of this product should be that of identifying the <strong>si</strong>milarities between the different banks’<br />
solvability requirements and to guide the client towards the most suitable credit program. The application should also<br />
provide a general model based on an extended analy<strong>si</strong>s of different credit risk evaluation models. Banks have<br />
developed sophisticated systems in an attempt to model the credit risk ari<strong>si</strong>ng from important aspects of their<br />
bu<strong>si</strong>ness lines. Such models are intended to aid banks in quantifying, aggregating and managing risk across<br />
geographical and product lines ��¤¨£���§¢¢¤���¢©��£�¤�©�����¨£�©�£���” by Basel, 1999, p. 8).<br />
The outputs of these models also play increa<strong>si</strong>ngly important roles in banks’ risk management and performance<br />
measurement processes, including performance-based compensation, customer profitability analy<strong>si</strong>s, risk based<br />
pricing and, to a lesser (but growing) degree, active portfolio management and capital structure deci<strong>si</strong>ons.<br />
The Romanian banking sector is characterized by the usage of traditional statistical methods rather than more<br />
modern ones such as expert systems based on neural networks or case based reasoning. Most of the Romanian<br />
financial institutions use very <strong>si</strong>mple methods of computing the credit score by taking into account several features<br />
and u<strong>si</strong>ng weights which are established by experts without making usage of statistical, mathematical or informatics<br />
instruments. The statistic regres<strong>si</strong>on is an important tool of evaluation in the Romanian credit institutions: some<br />
features are taken into account and their <strong>si</strong>gnificance is tested on a data set that includes both successful examples<br />
(clients that could pay back their debts to the bank) and defaulted credits. As a result, some variables are kept, while<br />
others are discarded. The following step in developing the evaluation model con<strong>si</strong>sts of associating a parameter to<br />
each characteristic. The level of this parameter depends on the type of variable and its level of <strong>si</strong>gnificance.<br />
Therefore a model is built, each factor having a certain parameter which depends on the influence of the variable on<br />
the result (success or default). Each time a new customer applies for a credit, his features are evaluated and replaced<br />
in the model, his credit score is computed and specialized persons from the credit institutions evaluate this result by<br />
comparing it to a certain cut-off value. The deci<strong>si</strong>on is taken depending on the comparison made between the<br />
client’s specific score and the cut-off value.<br />
(“�¢¤�£��£�£<br />
The neces<strong>si</strong>ty for an efficient credit scoring application<br />
The creation of an efficient credit scoring evaluation expert system is compulsory if we take into account the<br />
fact that the rigidity of the conditions required by banks when it comes to customers’ eligibility for credit granting<br />
has <strong>si</strong>gnificantly increased during reces<strong>si</strong>on. The scientific literature in the domain has presented a wide variety of<br />
credit risk evaluation models (survival analy<strong>si</strong>s, discriminant analy<strong>si</strong>s, the logit models and neural networks), each of<br />
them presenting not only great advantages, but also some disadvantages. The problem that appears is the need to<br />
minimize as much as pos<strong>si</strong>ble the risk associated with a certain type of model so that the result given by the model<br />
could be accepted with a high confidence level.<br />
Financial institutions around the world use a lot of expert systems (Moody’s RiskScore, FAMAS LA Encore<br />
or COMPASS (Bank of Scotland)), and an analy<strong>si</strong>s of the results achieved by these banks can represent a starting<br />
point in the process of improving of the existing models by taking into account of some new dimen<strong>si</strong>ons or of some<br />
new building techniques. A more efficient model could take into con<strong>si</strong>deration an essential aspect in the credit risk<br />
179
evaluation process: the selection of the optimal number of characteristics that have an influence over the risk and the<br />
association of weights depending on each factor’s importance.<br />
The improvement of credit risk evaluation models has become a very stringent problem during recent years if<br />
we take into account the number of failures reported by many financial institutions. Consequently, many statistic<br />
models have been studied, detailed and combined in order to diminish type one errors.<br />
The current state of art for credit risk evaluation models<br />
The current state of art in the domain on a national and international level can be resumed by presenting the<br />
main characteristics of the models introduced by different scientific publications.<br />
One example of credit risk evaluation model is Data Envelopment Analy<strong>si</strong>s (DEA) which, unlike the<br />
traditional statistic methods (discriminant analy<strong>si</strong>s, logit models and neural networks) does not require apriori<br />
information. (M<strong>IN</strong>, H., JAE and LEE, YOUNG-CHAN, 2008). The advantage brought by this model is undoubtful if<br />
we take into account the fact that one of the main problems in the way of an efficient credit risk evaluation is<br />
represented by the lack of historical data concerning the analysed customer.<br />
The oldest method used is Linear Discriminant Analy<strong>si</strong>s (LDA) which was introduced for the first time in<br />
1936 by Fisher. The method brings as a main instrument the Linear Discriminant Function (LDF). The main<br />
weakness of this method con<strong>si</strong>sts of the suppo<strong>si</strong>tion that there is a linear dependency among the input and output<br />
variables, fact which is not true for most of the practical cases.<br />
The literature has analysed the results obtained through the usage of the artifficial intelligence specific<br />
instruments : Artificial Neural Networks (ANN) : Probabilistic Neural Networks sau Multi-layer feed-forward nets.<br />
It has been noticed that the evaluations registered good results when it comes to customers that fail and are correctly<br />
clas<strong>si</strong>fied (this is a very important aspect : it is more important to have a high performance in the correct<br />
clas<strong>si</strong>fication of bad clients than in the correct clas<strong>si</strong>fication of good clients (the risk of not granting a credit to a<br />
customer evaluated with a higher risk than the real one)).<br />
The most difficult aspect in the application of neural networks in the credit scoring evaluation process is the<br />
difficulty of explaining the algorithm that gives the decis<strong>si</strong>on of accepting or rejecting certain customers. DEA<br />
requires only the input and output data sets in order to compute the credit score. It is computed as a ratio between<br />
total output and total input. Consequently, the observed units are clas<strong>si</strong>fied and an efficiency border is drawn, while<br />
the efficiency degree of the new units is going to be established depending on their po<strong>si</strong>tion related to the efficiency<br />
border. A very interesting study which compares neural networks with the traditional methods used in the credit<br />
scoring activity of Egiptian banks has been recently carried out. (Hussein Abdou, John Pointon şi Ahmed El-Masry,<br />
2008).<br />
Another method introduced for the first time in 1984 is the CART method (Clas<strong>si</strong>fication and Regres<strong>si</strong>on<br />
Tree) and it con<strong>si</strong>sts of the building of a maximal tree that contains all the units of the training set and can be divided<br />
into several trees out of which the most efficient one is chosen through cross-validation methods.<br />
In 1991 the MARS model (Multivariate Adaptive Regres<strong>si</strong>on Splines) appeared for the first time bringing the<br />
advantage of being combined with neural networks. The algorithm has two steps: firstly, a high number of ba<strong>si</strong>c<br />
functions are built, out of which some are going to be eliminated in the order of the least contributions (the cross<br />
validation method).<br />
Case Based Reasoning (CBR) is a model that has the goal to learn from practical failure cases and tries to<br />
build a pattern based on which to clas<strong>si</strong>fy the new customers.<br />
The RCSM model (Reas<strong>si</strong>gning Credit Scoring Model) is an algorithm made of two steps : the clas<strong>si</strong>fication<br />
of the applicants in « good » or « bad » cases and the redistribution of the « good » cases that have been incorrectly<br />
clas<strong>si</strong>fied as « bad ». in order to prove the model’s efficiency, researchers have tried to apply this algorithm on a data<br />
set related to credit cards. (Chun-Ling Chuang and Rong-Ho Lin, 2008)<br />
During the first phase the algorithm uses MARS in order to reduce the number of input nodes from the ANN<br />
(Artificial Neural Networks) and <strong>si</strong>mplify the networks. The <strong>si</strong>mplified neural network (a backpropagation network<br />
characterized by an unique input tier, a hidden tier and one output tier) is used for the clas<strong>si</strong>fication of the applicants<br />
into good or bad customers. The customers con<strong>si</strong>dered to be “bad” are going to be reas<strong>si</strong>gned through the CBR<br />
method, by identifying the <strong>si</strong>milarities existing between them, on one hand, and the good practical cases, on the other<br />
hand. The application has to search in the data base for those cases that present a series of <strong>si</strong>milarities with the new<br />
applicants. If the new applicant’s profile approaches more the successful cases than the failure ones, the person is<br />
reclas<strong>si</strong>fied as a “good” one and the loan is granted. The <strong>si</strong>milarity is measured through the “distance” between the<br />
two cases, by u<strong>si</strong>ng the nearest neighbor approach.<br />
Other examples of credit risk evaluation models described in the scientific literature are:<br />
• Multi Criteria Deci<strong>si</strong>on Making<br />
180
• Recur<strong>si</strong>ve Partitioning Algorithm<br />
• Mathematical Programming Approaches<br />
• Logistic Regres<strong>si</strong>on Analy<strong>si</strong>s (LRA)<br />
• fuzzy algorithms<br />
• Multivariate Conditional Probability Model<br />
• k-NN<br />
A general scoring methodology<br />
We believe that it is relevant to present the general steps of the research methodology when it comes to<br />
building an efficient credit scoring model:<br />
STEP 1:<br />
The observation data set is selected (the selection of those loan applicants for which there is a high pos<strong>si</strong>bility<br />
to find values for all the characteristics that could influence the associated risk)<br />
STEP 2:<br />
The identification of the potential characteristics for each candidate (factors:income, age, accommodation,<br />
marital status, etc.)<br />
STEP 3:<br />
The selection of the final characteristics (instruments: the statistical analy<strong>si</strong>s and domain experts). The result<br />
is a data set that contains the most representative indicators. It has to be mentioned that the indicators can be input<br />
indicators (previous loans, liquidities, buildings, etc.) or output indicators (in the case of the companies, one can take<br />
into con<strong>si</strong>deration whether the company finances itself from its own sources or its ability to pay interests from its<br />
own incomes).<br />
STEP 4:<br />
The computation of credit scores as a result of the chosen model.<br />
STEP 5:<br />
The validation of the results with the help of regres<strong>si</strong>on (econometric tool used in order to test whether the<br />
chosen variables are <strong>si</strong>gnificant for the result) (the chosen indicators represent the independent variables and the<br />
result is the dependent variable), the discriminant analy<strong>si</strong>s (in order to quantify the performance of this clas<strong>si</strong>fication<br />
method) and practical failure cases. It is interesting to analyze whether the results correspond to the results given by<br />
other clas<strong>si</strong>fication methods.<br />
STEP 6:<br />
The choice of the final credit scoring method.<br />
A general credit scoring model<br />
The model that we propose is based on semantic interoperability. Semantic interoperability is the ability of a<br />
set of “bu<strong>si</strong>ness” partners to coordinate their activity based on understanding the meaning<br />
¡�David<br />
of the communications<br />
that flow among them Frankel, 2007, p.<br />
(“�§�£�¤���¤�¡�¢£�¢©����¢�©�£��©���¤�©��£�¦��¤¢��¤¢©�£¨£�<br />
7)<br />
The semantic network for credit risk evaluation, in the way we see it, represents the communications<br />
involved in de<strong>si</strong>gning the customer’s profile. It con<strong>si</strong>sts of messages (data), as well as the transformation of those<br />
messages from one format to another, and is related to the information required by banks in order to determine the<br />
features of each client.<br />
In order to determine a minimalistic, general model for risk evaluation that can be used by customers to<br />
<strong>si</strong>mulate and calculate the chances they have in order to obtain a credit, we will implement a Service Oriented<br />
Architecture (SOA), which will integrate semantic web service communication facilities. In order to compute the<br />
scoring with the help of our general model integrated in a software application, several steps should be followed.<br />
These steps will be taken automatically and will partially be supervised by the user:<br />
Step 1: determining the common elements that banks take into account when creating the user profile. This<br />
can automatically be achieved by de<strong>si</strong>gning semantic networks for several banks and determine the <strong>si</strong>milarity<br />
between terms.<br />
Step 2: after obtaining a set of general features we propose a model based on scores. The series of sores are<br />
created after analyzing the risk evaluation models of several important Romanian banks.<br />
Step 3: when the series of scores is complete, we calculate a level of risk by combining the set of features<br />
with the scores. In this manner, the client can determine with a certain level of probability his chances of obtaining a<br />
credit.<br />
181
However, we are convinced that we can not obtain full semantic interoperability. Complete automation of<br />
all mapping deci<strong>si</strong>ons is probably not is very hard to achieve. For this reason, the solutions offered by this<br />
application are not 100% trustworthy. This happens because humans are involved in the evaluation deci<strong>si</strong>on process<br />
in the credit institutions. However, we hope that the results will be guaranteed with a maximum average of 45%.<br />
The de<strong>si</strong>gn of a software solution<br />
In order to develop a software solution we establish the following objectives:<br />
• de<strong>si</strong>gning the general context for modeling risk (identifying the main rules and knowledge, identifying the<br />
adaptive processes to the specific banks’ environment, specifying the semantic credit institutions’ interoperability<br />
elements, etc)<br />
• developing ontologies specific for every institutions which will structure the evaluation rules, and also<br />
developing a component for semantic web service de<strong>si</strong>gn for obtaining the characteristics in a OWL (Ontology Web<br />
Language) format.<br />
•de<strong>si</strong>gning efficient clas<strong>si</strong>fication algorithms for the rules used by banks(developing an automatic scoring<br />
system de<strong>si</strong>gning clas<strong>si</strong>fication algorithms based on Baye<strong>si</strong>an theory, implementing an algorithm for automatic<br />
renewal of the weights/scores system, implementing an efficient document mining algorithm).<br />
The proposed solution’s architecture will be web service oriented and will con<strong>si</strong>st of two components: a<br />
service implementing the semantic module and a service implementing the “bu<strong>si</strong>ness” logic (the effective module for<br />
calculating the scoring and determining the clients’ chances for obtaining a credit).<br />
The Service oriented architecture (SOA) represents a concept of great interest at software products’<br />
architecture level, because it facilitates interoperability by integrating services with web technologies. This type of<br />
architecture represents the ba<strong>si</strong>s for developing semantic web services that use ontologies from a certain domain of<br />
interest (a research theme of great interest at international level). The ontologies are a key technology for the<br />
semantic web. Ontology is a set of concepts from a particular field and the relationships between them and is used to<br />
facilitate the development of semantic models and necessary user specific information search, with the help of<br />
semantic queries. Furthermore, they enhance the development of personalized content and enable the decentralizing<br />
and the cooperation of content management, and also multilingual research.<br />
In order to represent ontologies, several languages were developed. These languages are based on XML.<br />
One of the most frequently used is OWL(Web Ontology Language). At the web service semantic specification<br />
languages level, the most important initiatives of extending the OWL language are:<br />
• OWL-S (US initiative)<br />
• WSMO (Web Services Modeling Language- the European initiative-logical and formal )<br />
• WSDL-S (W3C initiative)<br />
This service oriented approach assures solution portability and liability. As part of the service that is in charge<br />
with semantic proces<strong>si</strong>ng clas<strong>si</strong>fication algorithms and document mining algorithms will be implemented in order to<br />
extract the key concepts from each evaluation form. Afterwards, another method will de<strong>si</strong>gn the semantic network<br />
that is a hierarchic structure based on semantic and lexical relations, for each evaluation form. After the semantic<br />
networks were de<strong>si</strong>gned, a special algorithm for computing semantic <strong>si</strong>milarities (Lin algorithm) in semantic<br />
networks will be implemented. Based on this algorithm, the common features that banks take into account for<br />
developing clients’ profile, will be calculated. These parameters will be transmitted by the service description<br />
language (WSDL) to the web service that will implement the evaluation model. The evaluation model con<strong>si</strong>sts of<br />
associating a set of weights to each characteristic. For the client that solicits the evaluation a score will be computed<br />
in this manner and afterwards it will be compared to a cut-off value. This value is determined based on analyzing the<br />
scores obtained by the clients that successfully obtained a credit (they were able to pay it up) and also by analyzing<br />
the scores obtained by the clients that even though obtained a credit they were not able to pay it up (we will take into<br />
con<strong>si</strong>deration the clients’ profiles).<br />
The output of this general, orientative and minimalistic evaluation model, represents, with an average<br />
maximum confidence level of 45%, the client’s chances for obtaining a credit.<br />
So that this application to be complex, flexible, portable, distributed and to permit a high level of<br />
interoperability with the help of semantic web service, it is essential to implement automatic or semiautomatic web<br />
service modalities. This type of applications is con<strong>si</strong>dered to be the most suited for modeling the risk evaluation<br />
process for the activity of credit granting.<br />
182
In order to implement the requirements referring to assuring interoperability and also for offering automatized<br />
support in the risk evaluation process, it is necessary to improve the collaboration between the two web services (one<br />
implementing the semantic functionalities and one implementing the client’s reliability evaluation model).<br />
By unifying all the elements mentioned above, a new type of software application architecture, the OMG<br />
Model Driven Architecture (created by Object Management Group) and it is mainly used in developing interoperable<br />
and platform independent systems. The objective of this architecture is to model the credit granting process as close<br />
to reality as pos<strong>si</strong>ble. The processes are seen as activities collections connected both logic and semantic.<br />
Conclu<strong>si</strong>on<br />
The paper presents some general aspects related to the neces<strong>si</strong>ty of developing an efficient credit scoring<br />
evaluation model. Some of the most discussed models in the scientific literature are described and both their<br />
advantages and disadvantages are emph<strong>si</strong>zed.<br />
Consequently, a general methodology for building a credit scoring evaluation model is proposed and the<br />
authors introduce some theoretical aspects related to web semantics and ontologies. These tools can be used in order<br />
to develop a more efficient software application.<br />
The proposed application offers a specific approach both at conceptual and also at technologic level but it is<br />
in connection with the present standards and research. To be more specific, the project will have a service oriented<br />
architecture, will implement a specific semantic for the Romanian language, but also it will be able to offer support<br />
for English, and will implement ontologies for credit granting rules modeling.<br />

Introduction<br />
In this article we study GIS (Geographic Information System) in terms of performance gained from the use of<br />
specific algorithms. We study the QuadTree and R-Tree algorithms, in terms of architecture and implementation;<br />
also we compare their efficiency, both among themselves and compared with clas<strong>si</strong>cal methods of linear search.<br />
Next, we present briefly GIS systems, the way information is stored in these systems, and inherent problems that<br />
arise.<br />

A GIS integrates hardware elements, software and data for capturing, managing, analyzing, and displaying<br />
geographically related information. This system allows viewing, understanding and querying data in multiple ways<br />
that reveal relationships and patterns in the form of maps, reports or charts.<br />
A GIS helps with answers to questions and solving problems by looking at existing data in an intuitive and ea<strong>si</strong>ly<br />
distributed way.<br />
A GIS can be seen in three different ways: in terms of a database (database view), the map (map view) and model<br />
(model view). In Database View the GIS is seen as a structured database that describes the world in geographical<br />
terms. In View map the GIS is seen as a set of intelligent maps and sketches which characterized relations over the<br />
Earth. In Model View the GIS system is seen as a set of tools for information transforming for obtaining new derived<br />
datasets from existing data sets. These tools extract information from existing data, apply analytic functions, and<br />
write results into new derived datasets.<br />
Data representation in a GIS system can be done either in Raster or Vector way.<br />
Raster mode is essentially any type of digital image represented as an array of pixels. The pixel is the smallest unit of<br />
an image. A combination of these pixels will create an image. This representation con<strong>si</strong>sts of rows and columns of<br />
cells, each cell with one stored value. Raster data can be images (raster image) with each pixel containing a value,<br />
184
usually a color. Additional values recorded for each cell may be a discrete, defined by the user with relevant GIS<br />
system, a continuous value, such as temperature, or a null value if no data available. A raster cell that stores only one<br />
value can be extended by u<strong>si</strong>ng raster bands to represent RGB colors (red, green, blue), or an extended attribute table<br />
with one row for each <strong>si</strong>ngle cell unique value. Resolution in raster mode is pixel <strong>si</strong>ze in phy<strong>si</strong>cal units (eg distance).<br />
Raster data are stored in various formats, from standard file structure of TIF, JPEG, etc.. and directly in binary data<br />
fields (BLOB) of common databases.<br />
Vector mode is used especially in GIS systems where, geographical features are often expressed as vectors, by<br />
con<strong>si</strong>dering the elements as geometric forms. Various geographical elements are expressed by different types of<br />
geometry forms:<br />
• Points - zero-dimen<strong>si</strong>onal points are used for geographical elements that can be best expressed by a <strong>si</strong>ngle<br />
point of reference, in other words, <strong>si</strong>mple location. There in no po<strong>si</strong>blity to make any measurements in this<br />
case.<br />
• Lines - The lines are used for one-dimen<strong>si</strong>onal linear elements such as rivers, roads, topographic lines, and<br />
so on. Lines also allow measurement of the distance.<br />
• Polygons - Polygons are two-dimen<strong>si</strong>onal elements that are used to represent a geographical area on the<br />
surface of the Earth. Polygon features make it pos<strong>si</strong>ble to measure the perimeter and area.<br />
In order for the GIS to be useful, they must work properly and provide the requested information timely manner. The<br />
common problems of such systems are scalability and speed of proces<strong>si</strong>ng user requests. When the system operates<br />
with more elements, the scalability problem becomes more pronounced issue. Problems in repeated rendering of<br />
large number of elements appear (eg moving the map in a specific direction) when finding a particular item, and<br />
querying the system for the po<strong>si</strong>tion of an element, inserting or deleting an item, etc..<br />
We will use as an example of these problems, the selection of an object on the map. This function allows the<br />
identification of an item on the map via the mouse cursor for the purpose of viewing or editing features. Although the<br />
function used for detecting the existence of an object under mouse cursor does not have a high complexity, (in<br />
general O (1) for points, lines and most types of polygons), regular repeated calls to check for each item on the<br />
screen takes too long. When working with an overview of the entire structure of the elements of the screen coincides<br />
with the total number of elements of the whole system. In this case the complexity associated with the operation of<br />
finding the item selected by the user's cursor is O (n) (where n is the total number of items).<br />
For a large number of items in the orders of thousands, hundreds of thousands or even millions, a linear search is<br />
very highly inefficient. Later we will investigate ways to search faster, u<strong>si</strong>ng spatial partitioning, and we study the<br />
influence this class of algorithms on performance.<br />
Spatial partitioning techniques and systems<br />
In mathematics, the concept of spatial partitioning refers to the process of dividing Euclidian in two, disjunctive<br />
subspaces, so any that any given point, is owned by only one of subspaces. Spatial partitioning schemes are most of<br />
the time hierarchical in the sense that a region of space can be subdivided into several regions which are in turn<br />
subdivided into a recurring manner. All partitions generated according to the above process can be organized as a<br />
partitioning tree. These techniques include BSP trees, QuadTrees, Octrees, kd trees, R-Trees, etc..<br />
Spatial partitioning techniques play an important role in computer graphics. They are generally used for 2D, 3D<br />
space organization and storage. Storing objects in space partitioning structure facilitates rapid response to a series of<br />
geometric queries, colli<strong>si</strong>on detection for 2D, spatial indexing, occlu<strong>si</strong>on solution to the problem of spatial objects<br />
and so on.<br />
Next we study how does the use of QuadTree and R-Tree impacts performance in contrast with the complexity<br />
introduced in the code.<br />
QuadTrees<br />
185
A QuadTree is a data structure characterized by nodes that have a maximum of four children. We used this tree for<br />
recur<strong>si</strong>vely divided the 2D into four quarters of rectangular shape. For each quarters obtained we verify that the<br />
number of elements contained dose not exceed a preset limit. If this is exceeded the quarter is sub-divided into four<br />
quarters, continuing the process recur<strong>si</strong>vely until all the regions obtained by splitting respect maximum number of<br />
objects contained rule.<br />
Figure 1. Example of space divi<strong>si</strong>on u<strong>si</strong>ng the QuadTree algorithm and the internal tree representation<br />
Some restrictions identified when u<strong>si</strong>ng QuadTrees are:<br />
• All the space that needs to be indexed has to known in in the beginning<br />
• The index tree has to be entirely rebuit if the space indexed by it has been shrinked or enlarged<br />
The procedure used for creating a QuadTree<br />
QuadInsert (i, n) [insert into the node n] is trying to insert in node n. Check the capacity of the current node if node is<br />
full and the node was expanded previously recur<strong>si</strong>vely call the add item function for the child node that contains it.<br />
Otherwise, if the current node contains the maximum number of elements N, and has not been expanded, the node is<br />
expanded by creating the four child nodes. Information is then inserted to the child node to which it belongs. Finally,<br />
if the current node is less than N elements and is a leaf the information is added to it.<br />
The creation of the tree is achived by repeated calls of the QuadInsert procedure for each item of the system.<br />
QuadBuild: Create QuadTree, initially empty. For each element of the system, call the QuadInsert (i, root).<br />
After creating the QuadTree by repeated insertion, it is pos<strong>si</strong>ble to contain empty leaf nodes. These empty leaf nodes<br />
are removed.<br />
The complexity depends on the distribution of tree elements in the area that is indexed. The cost of adding an<br />
element is given by the depth calculated as the number of nodes tran<strong>si</strong>ted to reach the root of the tree from where the<br />
item is added. This can be computed by counting each recur<strong>si</strong>ve call of the QuadInsert. Each time the function is<br />
called for adding an item the depth increases by one.<br />
If all items are closely clustered, in a very small area the complexity is high because a leaf nodes will be at a great<br />
depth. However the maximum depth is controlled by the number of bits used to represent the po<strong>si</strong>tion of items. This<br />
number of bits is virtually constant in the complexity calculation. Thus if the tree is evenly distributed so that all<br />
leafs have the same depth, cost to incorporate all elements would be O (NlogN) = O (Nb)<br />
Disadvantages of this technique<br />
If geometric divi<strong>si</strong>on fails to reduce the number of elements for each quarter (ie the overlapping elements, elements<br />
which intersect each other), the capacity should be increased to allow the algorithm to continue execution. For<br />
example, if the maximum capacity of a node is eight, if they are nine elements to a certain point (x, y), the divi<strong>si</strong>on<br />
186
would produce three empty quarters, and one which contains nine points, and so on. Because the tree must allow<br />
more than 8 items per node, QuadTree complexity decreases to almost O(N) for datasets with arbitrary geometry<br />
R-Tree<br />
R-trees are balanced trees <strong>si</strong>milar to B-trees. The tree structure is de<strong>si</strong>gned in a manner in which it tires to minimize<br />
the number of nodes that need to be search in order to get to the requested element.<br />
A leaf node contains more tuples. Each tuple con<strong>si</strong>sts of an index to an object and the n-dimen<strong>si</strong>onal bounding box<br />
(the rectangle of n-minimum volume that contains the object). When working in 2D space the bounding box is<br />
actually the minimum area rectangle that contains the object. Non-leaf nodes contain tuples con<strong>si</strong>sting of an index to<br />
a child node <strong>si</strong>tuated at a higher level of depth and the bounding box that contains all the rectangles associated with<br />
that child node.<br />
The R- Tree construction must comply with the following rules:<br />
• Each leaf node contains between nmin and nmax tupluri (index rectangle) except the root node.<br />
• Each tuple of leaf nodes contains an index to an object space and the smallest rectangle containing n<br />
dimen<strong>si</strong>onal object.<br />
• Each non-leaf node has between nmin and nmax children except the root node.<br />
• Each tuple in the non-leaf node contains a pointer to an index-child node and the smallest rectangle containing<br />
the rectangles in the child node.<br />
• Root node has at least two if not leaf node.<br />
• All leaves have the same depth (the tree is balanced)<br />
The maximum depth in the worst case is |lognminN|-1 and is achieved when all nodes are just branched and they<br />
contain the minimum number of elements. The maximum number of nodes is +1 and is achieved when the<br />
fill factor of all nodes except the root is . In this particular case each non leaf nodes have the minimum number<br />
of children, and the leaf nodes index objects.<br />

The search algorithm in a R-Tree<br />
Figure 2. R-Tree, internal structure and graphical representation<br />
The search algorithm in a R-Tree is <strong>si</strong>milar to the search in a B-Tree. However, unlike B- Trees, the search is<br />
required through several sub-trees of the node, making it impos<strong>si</strong>ble to predict the performance. This due to the fact<br />
that in R-Trees the information cannot be stored ordered in the node (the child nodes of a node don’t respect any<br />
hierarchy),The inserting algorithm structures the data so that it will allow search algorithms to eliminate the<br />
irrelevant search subspaces focu<strong>si</strong>ng the only to regions close to the area searched.<br />
If the algorithm is required to search items contained in a rectangle S the main steps are:<br />
Starting from the root node if the node is not a leaf node, for each sub-tree of the current node check whether the<br />
rectangle is associated to overlaps with S. For all entries that overlap is call the search function recur<strong>si</strong>vely starting<br />
from the sub-tree root.<br />
If current node is a leaf node, check all tuples (spatial object, "bounding box") whether S the search area overlaps<br />
with the "bounding box". If they overlap the item is added to the result list.<br />
Inserting objects into a R-Trees<br />
Inserting objects into a R-Trees is done in the same manner the insertion would be done in B-Tree index except that<br />
in this case the spatial information indexed is added to leaf nodes. Nodes reach the maximum allowed nmax elements<br />
are expanded and the stored tuples are propagated to lower levels.<br />
Application<br />
188
To illustrate the usefulness and the performance increase gained by u<strong>si</strong>ng space partitioning algorithms, we<br />
implemented a GIS application that can work alternatively with both data structures, R-Trees and QuadTrees. The<br />
use of tree structures will facilitate the rapid retrieval of a set of requested information. One of the places where the<br />
retrieval is mostly used is when finding the item that is hovered with the mouse cursor; in programming that is<br />
necessary for implementing the events such as "mouseover". The speed of these searches needs to be as high due to<br />
the high frequency of queries. Each time the mouse cursor is moved the search has to be reissued. An increased in<br />
the time need to retrieve the information leads unwanted lag in a place where the user expects the application to<br />
respond almost instantly. We chose this method of testing after we studied of processor time consumed by calls to<br />
various functions of GIS applications. The study revealed that the “mouseover” is consuming a substantial portion of<br />
the processor, and in the same time is real-time critical in terms of user interface.<br />
At the first glance the optimization of not investigating all the elements of the system just those vi<strong>si</strong>ble in the screen,<br />
thus reducing the number of pos<strong>si</strong>ble items to be selected is sufficient, but this method is not sufficient, because the<br />
screen can contain an overview of all elements of the system. In this <strong>si</strong>tuation the proposed optimization dose not<br />
reduce the number of elements that need to be investigated, further improvements are required.<br />
In order to obtain increased performance when retrieving the item we propose u<strong>si</strong>ng indexes create based on R-Tree<br />
or QuadTree. To highlight the performance we have implemented in the GIS the three search methods: linear,<br />
QuadTree indexed and indexed by R Tree, with the ability to switch between them. To best evaluate performance we<br />
used synchronization mechanisms to ensure "critical section" in the search functions.<br />
In order to analyze the degree of scalability, the GIS system was populated it with data sets of different <strong>si</strong>zes,<br />
generated randomly. The <strong>si</strong>ze of data sets increases from 1 item to 10 million items, increa<strong>si</strong>ng the powers of his 10.<br />
Since the expected complexity of algorithms for search in tree R and Quad is logarithmic, we chose data sets whose<br />
<strong>si</strong>ze increases exponentially. Items have a stable <strong>si</strong>ze (rectangle of fixed area) and are arbitrarily placed on the map<br />
application.<br />
189
Below we present the results obtained from the conducted tests:<br />
Required memory test<br />
In implementation of the indexing algorithms data<br />
objects references were used instead of the actual<br />
object. In this way the tests for required memory will<br />
only count the memory needed to store the actual<br />
index. In the case of linear algorithm the memory<br />
used be<strong>si</strong>de the actual data objects is zero.<br />
It is noted that as the number of elements increases<br />
QuadTrees begins to use more space than the R-<br />
Tree. As the number of elements increase QuadTree<br />
needs to subdivide the space in even smaller<br />
divi<strong>si</strong>ons in order to accommodate all the data object<br />
references. Note that these divi<strong>si</strong>ons consume more<br />
space when items are clustered tightly rather than<br />
when they are distributed relatively evenly in the<br />
plan.<br />
Search response time<br />
Search time is as expected, in proportion to the<br />
complexity of search algorithms used. When we use<br />
the linear space search that iterates trough all the<br />
elements, the complexity is O(N). We can see that<br />
time is almost directly proportional to the number of<br />
items. When we use indexes that have a logarithmic<br />
nature of complexity O(logN) the time seems to have<br />
a line representation in the chart that has a<br />
logarithmic X Axis.<br />
Chart no. 4 shows the search time needed for linear<br />
serach versus time obtained by u<strong>si</strong>ng QuadTrees and<br />
R-Trees. It is noted that at relatively small number of<br />
elements, the difference is not distinguishable (up to<br />
500). When operating with a small number of<br />
elements linear search is faster because of the high<br />
speed of brow<strong>si</strong>ng versus traver<strong>si</strong>ng index trees.<br />
However, if the number of elements increases, the<br />
linear search times get extremely weak relative to<br />
the performance obtained from index trees.<br />
Chart no. 5 details the results of the two compared<br />
tree structures used without linear search included. It<br />
can be seen that a large number of elements that our<br />
implementation of R-Trees runs faster than<br />
QuadTree.<br />
Note that the distribution of elements in the plan is<br />
important. When a uniform distribution used, the<br />
performance of the two methods are close, but when<br />
the distribution is clustered, R-Tree out performs<br />
QuadTree.<br />

Conclu<strong>si</strong>ons<br />
The de<strong>si</strong>gning of GIS systems has to be made having regard for the de<strong>si</strong>red performance. In the de<strong>si</strong>gn stage, in order<br />
to maintain performance levels, analyses regarding resource consumption have to be done in order to choose which<br />
algorithms are suitable.<br />
In this article we showed that the <strong>si</strong>mple use of a linear searching in order to resolve spatial query is a huge consumer<br />
of resources (CPU time) when working with a large number of entries. To reduce this consumption we presented two<br />
methods of indexing: the trees and R trees Quad and we showed that these methods logarithmically reduce the time<br />
needed to execute the query.<br />
However this improvement has a cost given by the construction and maintenance of the indexing tree. Both<br />
algorithms consume additional resources: memory to store the tree and CPU time to construct and update. We can<br />
say that the mechanisms used for spatial indexing consume more time to add, delete objects and decrease the time<br />
needed for querying / retrieval. This behavior is <strong>si</strong>milar to the index structures in the relational database.<br />
The performances obtained u<strong>si</strong>ng QuadTrees and R-Trees are <strong>si</strong>milar. Both methods reduce the search time by a<br />
logarithmic law given by the searching in a hierarchical tree structure. However QuadTree is less robust due to<br />
several exceptional cases leading to poor performance and even crashes if not treated separately. QuadTree is not a<br />
balanced tree structure and because of this it cannot ensure a unitary homogeneous performance across queries<br />
issued on all regions. The memory consumption is also con<strong>si</strong>derably higher for QuadTree.<br />
According to study it is advisable to use spatial indexing when working with more than 10 4 entries and becomes<br />
imperative to be used when the number of data objects exceeds 10 5 .<br />

Introduction<br />
Digital economy assumes completing economic transactions u<strong>si</strong>ng IT&C. The explo<strong>si</strong>ve development of IT&C<br />
leaded to an ascending evolution of the volume of online economic transactions. The increa<strong>si</strong>ng volume of online<br />
economic transactions leads to the ari<strong>si</strong>ng of a new category of applications that must fulfill the users’ requirements.<br />
The transaction number grows through the increase of the number of transactions made by existing users and,<br />
mainly, through attraction of new user intro the system. The increased number of users leads to the application’s<br />
update as to support new technologies that increase the quality level. The increase of transactions also leads to an<br />
increase in the application’s security requirements. Citizen oriented informatics applications came to answer the<br />
users’ requirements regarding online informatics applications’ qualities.<br />
Citizen oriented informatics applications<br />
Citizen oriented informatics applications are a new category of applications de<strong>si</strong>gned to solve problems that a very<br />
large number of persons deal with. Citizen orientated informatics applications, compared to other informatics<br />
applications, have as their objective to maximize the degree of customer satisfaction. The other applications serve the<br />
purpose of solving problems of the organization for which they are developed. If the effects of clas<strong>si</strong>c informatics<br />
applications reflect in other areas of the beneficiary, the citizen oriented applications bring in profit for the owners<br />
directly proportional to the degree in which the citizens that use them solve their problems. COIA are integrally at<br />
the customer’s disposal, which can solve its problems u<strong>si</strong>ng it while the clas<strong>si</strong>c applications interact with citizens to<br />
solve problems for the organization, the citizen being only the operator, not the beneficiary. The essential differences<br />
between citizen orientated and clas<strong>si</strong>c informatics applications are:<br />
- COIA are created in order to solve citizen problems, while clas<strong>si</strong>c applications are created to solve the<br />
companies’ problems;<br />
- COIA offer the citizens for use a succes<strong>si</strong>on of steps to solve their problems, while the clas<strong>si</strong>c applications<br />
focus on the steps for solving the company problems;<br />
�¤�¤¨���¤���£¢¤��£�����¢©§��¤��£�©�£���¤�����©¢¤�¢¤�¤��¤��<br />
- within COIA the information which is presented is that in of which the citizen is directly interested, while<br />
clas<strong>si</strong>c applications focus on promoting the company and its products and services.<br />
- the application is developed only after the target group is studied and all steps of the developing cycle are<br />
realized taking into account the target group’s characteristics;<br />
- COIA are free applications, the owner’s revenue being dependant of the number of users the application<br />
has; clas<strong>si</strong>c applications have acqui<strong>si</strong>tion and running costs;<br />
- COIA are online applications to be available regardless of time and space;<br />
- COIA are characterized by high security level compared to clas<strong>si</strong>c applications for witch security is not an<br />
important issue.<br />
Con<strong>si</strong>dering the advantages of COIA it is necessary that all applications be characterized to a certain degree by<br />
citizen orientation. Clas<strong>si</strong>c application are replaced with citizen orientated ones, which come with solution for their<br />
problems.<br />
The quality characteristics system<br />
Con<strong>si</strong>dering the fact that COIA means resource allocation and working independently of the owner and<br />
developer, they must be gifted with the following quality characteristics:<br />
- coverage, meaning if the citizens need to solve within problem P, for which COIA is built, the sub problems<br />
SP1, SP2, ..., SPN the application must implement components that correspond to all the N sub problems;<br />
192
- correctness establishes the measure in which perfect correspondence is achieved between the results from<br />
the test data sets and the effective results obtained inputting them; a test data set SDTi contains inputs,<br />
intermediary results, and final results; in the testing process data is inputted and intermediary SDTi results<br />
are compared with the intermediary results returned by the application, respectively the final results from<br />
the test data set and the application returned final results; correctness is relevant when there is no doubt<br />
regarding the quality of the test data sets;<br />
- completeness ensures that all proces<strong>si</strong>ng made in all pos<strong>si</strong>ble <strong>si</strong>tuations, to solve a sub-problem, that any of<br />
the target group members comes across;<br />
- reliability gives the measure in which the application executes without incident the necessary proces<strong>si</strong>ng for<br />
solving citizen problems; this characteristic depends also on the hardware components on which the<br />
application runs on; a reliable COIA must execute proces<strong>si</strong>ng without incident for the citizen even if in the<br />
computer network it runs in machine defects are present;<br />
- COIA maintenance measures the effort level necessary to update; knowing COIA characteristics, their<br />
update is frequent to fulfill citizen requests, thus a high level of maintenance must characterize this kind of<br />
applications; the maintenance costs must be low to allow updating the application and avoiding rede<strong>si</strong>gning<br />
it;<br />
- auto-configurable; COIA must auto-configure itself according to the most frequent citizen problems; for this<br />
the application must record the frequency of problems which it solves, at a certain time interval, by autoconfiguration<br />
it shortens the time needed to solve the most frequent problems; the reconfiguration must take<br />
into account the data sets recorded in the past for a higher level of efficiency;<br />
- user friendly; COIA addresses a large and diverse target group compared to a clas<strong>si</strong>c informatics<br />
application, this leads to the need of developing a easy to use interface;; as the majority of citizens that use<br />
the application are not IT specialists, the friendly GUI must characterize COIA and allow all users to solve<br />
their problems;<br />
- flexibility represents the ability of the application to adapt to messages received from the environment;<br />
when in use by the citizens the application must be able to adapt their demands and give adequate solutions<br />
to their problems;<br />
- easy to return to previous steps; input data refresh must be done in a easy and logical way, messages must<br />
be clear;<br />
- time memory which assumes storing citizen data, activities, and input data such that the users will not be<br />
required to input them again when u<strong>si</strong>ng the application in the future, only to update them if needed;<br />
- portability refers to the pos<strong>si</strong>bility of running the application with no regard to the hardware platform used;<br />
taking into account the large number of application users and their diver<strong>si</strong>ty con<strong>si</strong>dering the used hardware<br />
platform, it is vital that COIA will run on as many hardware platforms as pos<strong>si</strong>ble; with no regard to the<br />
platform COIA offers its users the same functionality, a function is not allowed to be available on a<br />
platform and unavailable on another one;<br />
- computation preci<strong>si</strong>on refers to the number of decimal places stored during computation; for COIA it is<br />
important the computation preci<strong>si</strong>on is at its highest level because at a large number of users errors are<br />
propagated and preci<strong>si</strong>on is reduced;<br />
- security represents the application’s ability to ensure users’ data and actions protection against criminal<br />
attacks.<br />
Citizen oriented informatics application’s security is a vital quality characteristic that must be fulfilled to the highest<br />
degree. The application must guarantee that the user’s data and actions are protected against criminal attacks.<br />
COIA security<br />
Taking into account the high number of users of COIA, the security is a very important aspect. Each user must<br />
access only his data and must realize actions only on his account. The user’s access to COIA must be granted based<br />
on username and password only if the application implies economic activities. For COIA de<strong>si</strong>gnated to expose<br />
information the access must be free, only paid services being subject to authentication.<br />
Authentication is defined as the process of establishing if an object is authentic. For COIA this means to establish if a<br />
user is the one he claims to be.<br />
193
Figure 4 Authentication mechanism<br />
The functioning mechanism of informatics applications’ authentication procedure is presented in (Error! Reference<br />
source not found.). The user launches a request of authentication or password reset. The authentication service<br />
verifies if the user supplied the password associated to his account and grant access to the application’s components<br />
if it checks. If a password reset request is received, it is forwarded to the password reset service. If the request is<br />
authentication type but the password doesn’t match the account, the user is requested other credentials.<br />
For COIA, the knowledge based authentication assures a high degree of security and offers the users a comfortable<br />
authentication method.<br />
Knowledge based authentication is used as a primary system or as sub-system for authentication in citizen<br />
orientated applications. This type of authentication is based on a set of factoids which represents knowledge<br />
possessed by the user used to identify him from a set of users.<br />
A factoid is represented under the form of a pair: �§�£���<br />
where:<br />
Incorrect<br />

password<br />

The factoids have the following characteristics:<br />
- memorbaility represents the ease with which the users remembers the data he entered;<br />
- guessability is the ease through which one is able to guess the information given by the<br />
user without having any prior knowledge which relates to him;<br />
- <strong>si</strong>mplicity represents a characteristic which is closely tied to memorability, is the factoid<br />
is <strong>si</strong>mpler then memorability increases;<br />
- usability is the characteristic that allows an easy use of the factoids registered in the<br />
system;<br />
- unicity is the characteristic that guarantees that one factoid will not resemble another in<br />
the set;<br />
- portability insures the correct behavior of the knowledge based authentication system<br />
regardless of the platform;<br />
- familiarity is a sub-characteristic of guessability which regards the personal character of<br />
knowledge within the factoid.<br />
In order to increase the security level a set of factoids<br />
��¡¢is<br />
�¤§�£¤��¤��The<br />
used where the factoid<br />
and the factoid elements in the set have the following properties:<br />

level. ££¥£¤ �££��£�¥�£¤��¤� �£¥�¤ � �£§�££��£� �§��¨� �§<br />
In (figure 2) the environment of the factoids is presented, it is composed from 2 major elements the user and<br />
the system. The user supplies the factoids to the authentication system which after running a cross reference with the<br />
factoids stored by the user beforehand accepts or denies access to the privileged resources.<br />

Conclu<strong>si</strong>ons<br />
Citizen oriented informatics applications redefine the concept of informatics application to correspond the target<br />
group’s requirements. These fulfill a set of quality characteristics that the clas<strong>si</strong>c applications don’t fulfill or do it in<br />
a low degree. Security is an important characteristic for the COIA the overall quality of the application being<br />
strongly influenced by it. The usual authentication method the informatics applications use is the one that uses an<br />
username associated to a password. �£<br />
U<strong>si</strong>ng knowledge based authentication in citizen orientated applications has the following advantages:<br />
- the degree of failed authentication attempts is reduced, con<strong>si</strong>dering the fact that the<br />
factoid set is large and they all contain knowledge that the user is familiar with;<br />
- the degree of risk involved by dictionary attacks is reduced because the factoids<br />
contained in the set associated with the user are randomly picked and they have a<br />
personal character which is unknown to third parties , as the knowledge contained by the<br />
factoids must only be known by the user and partially by third parties.<br />
Disadvantages of knowledge based authentication are related to the public character of the knowledge in the<br />
factoids and their availability in the virtual space. This is why it is recommended to use information as diverse as<br />
pos<strong>si</strong>ble and with reduced availability.<br />

1. Introduction<br />
The dominant logic of companies, the norms and beliefs that the companies formulate and adopt, a way of<br />
thinking with respect to the strategies they implement, has always been that maximum results are obtained by fully<br />
u<strong>si</strong>ng the available resources they dispose. This logic is thought to ensure security and stability in every organization,<br />
and was always seen as the best attitude towards achieving its objectives, having no doubt in succeeding, but as it is<br />
demonstrated, the enemy of change and transformation is the constancy of inertia. Innovative organizations should<br />
combine tradition and gold rules with new ideas, new bu<strong>si</strong>ness models and practices in order to be a step ahead their<br />
competitors, to be receptive to the challenges of the industry in which they perform, to overcome the barriers to<br />
continuous improvement. The most difficult issue is to identify those norms and beliefs that impede the bu<strong>si</strong>ness<br />
processes to deliver the best outcomes taking into account the overall strategy of the firm, customer’s needs and the<br />
way competitors behave on the market. “At the industry level, thought leaders introduce beliefs that create an<br />
industry culture, or a set of firmly held bu<strong>si</strong>ness norms that become conventional wisdom. At the same time,<br />
individual companies have prevailing ideologies and principles to which they adhere without often challenging them.<br />
The most successful industries and enterprises are especially susceptible to established beliefs that become dogmas”.<br />
(iSixSigmaEurope, 2009, )<br />
Traditionally, the optimum performance of a system is con<strong>si</strong>dered to be the result of the individual<br />
performance of its component parts; if all its components are u<strong>si</strong>ng their maximum capacity, the system as a whole<br />
will deliver the best results. However, a number of theoreticians have demonstrated the oppo<strong>si</strong>te<br />
The concept of system constraints was introduced for the first time by Dr.Eliyahu Goldratt in the Theory of<br />
Constraints (TOC) which is essentially about change. (Dettmer, 1997, p.11) This theory was latter on completed with<br />
a set of tools and the logic reasoning supporting them, based on fundamental assumptions, known under the name of<br />
the Thinking Processes, in Goldratt’s book “It’s Not Luck”. These tools are: the current reality tree, the conflict<br />
resolution diagram, the future reality tree, the prerequi<strong>si</strong>te tree, the tran<strong>si</strong>tion tree The TOC Thinking Process defines<br />

those actions required to improve a company given the current <strong>si</strong>tuation and to guide each step to its sometimes not<br />
so obvious conclu<strong>si</strong>on. It provides the answer to the three fundamental questions every manager should con<strong>si</strong>der:<br />
what to change, what to change to and how to cause the change. And it is used to guide the implementation of the<br />
TOC and to aid in creating breakthrough solutions. This can also be of <strong>si</strong>gnificant importance to the implementation<br />
of the TOC-based system by ensuring that any unde<strong>si</strong>rable effects that manifest themselves during the<br />
implementation process are eliminated. (Stein, 2003, p.258)<br />
2. Policy constraints – the real challenge<br />
Policies are the rules and measures that govern the way organizations go about their bu<strong>si</strong>ness. Policies<br />
determine the location of the phy<strong>si</strong>cal constraints and the way in which they are managed. Policies define the<br />
markets that the organization serves, how products are purchased from suppliers, and they are the work rules in<strong>si</strong>de<br />
the factory. They are managerial constraints that inhibit the system’s ability to continue to improve.<br />
Policies, both written and unwritten, are developed and followed because people, through their belief<br />
systems, develop and follow them. Managers institute rules and procedures that enable the people in the organization<br />
to make deci<strong>si</strong>ons and take actions that will yield good results for the company. However, organizations nowadays<br />
are riddled with inappropriate policies. (Scheinkopf, 2000, p.18)<br />
The general belief is that policy constraints are ea<strong>si</strong>er to change because they only require reformulating<br />
rather than the replacement of a new piece of equipment, which is, theoretically, a bigger effort, both phy<strong>si</strong>cal and<br />
financial. In practice, two things conspire against breaking a policy constraint, which make it even more difficult:<br />
first, identifying the policy constraint that causes the resultant effects is a complex issue, as it is very difficult to trace<br />
a chain of cause and effect back to a root cause; second, identifying the constraint is not enough – it is usually<br />
somebody else’s task, somebody whose cooperation is essential to change it. This is frequent in organizations that<br />
have several departments because persuading a lot of people to act on a policy constraint they might be respon<strong>si</strong>ble<br />
for is not an easy job. It takes the acceptance of policy makers of the respon<strong>si</strong>bility for the company’s poor<br />
performance, but few people are secure enough in their po<strong>si</strong>tions and able to admit they own a problem and that it is<br />
in their hands the deci<strong>si</strong>on whether to undertake or not the change.<br />
Two pos<strong>si</strong>ble reactions can appear when people are told there is something wrong in their system and when<br />
the policy is pointed out as having negative influence: one is denial – “it’s not really a problem, it’s your<br />
imagination”; the other is the justification of the need for such a policy – “Well, maybe you’re right…but we need to<br />
have this policy because…”.(Dettmer, 1998, p.22) No matter the reaction, people are likely to re<strong>si</strong>st accepting the<br />
respon<strong>si</strong>bility and undertaking to do something about it. It is the human re<strong>si</strong>stance barrier that total quality<br />
management and just about every other management innovation has come up against as it is a great struggle to try to<br />
change the status quo.<br />
For this reason, Goldratt contends that policy constraints are like bad laws – it not only takes to persuade a<br />
majority, it is also crucial to overcome re<strong>si</strong>stance of the parties who have special interests for the system to work to<br />
their advantage; which makes them more difficult to identify and break.<br />
3. The tools for breaking policy constraints<br />
3.1 The current reality tree (what to change)<br />
It is very well known that by identifying accordingly a problem, it is already half-solved. The current<br />
reality tree is a tool that helps managers to examine the cause – and – effect logic behind the policies, plans and<br />
strategies they want to implement. At the beginning, there are the unde<strong>si</strong>rable effects that by their presence,<br />
communicate the existence of a problem, a phenomenon that is out of its actual pace and frequency, so to say; an<br />
element that is disturbing the order and the well-functioning of the other elements in the system. Starting from this<br />
particular point, the manager can work back at tracing the root causes that generate all the unde<strong>si</strong>rable effects<br />
experienced.<br />
This is the purpose of the current reality tree: to communicate to the ones respon<strong>si</strong>ble for the system what to<br />
change – how should the policy be changed in order to have the greatest po<strong>si</strong>tive effect on the organizational system.<br />
But before making this change, the issue that needs to be tackled should be very well identified, meaning that the<br />
policy constraint that interferes in our system must be correctly determined.<br />
Breaking a constraint requires change. Sometimes that change can involve a <strong>si</strong>gnificant financial<br />
investment. And even if it does not, breaking a constraint often represents such a <strong>si</strong>gnificant change to the way<br />
bu<strong>si</strong>ness is done that it results in con<strong>si</strong>derable organizational turbulence or confu<strong>si</strong>on. Whether the effect is financial<br />
or functional, it makes no sense to commit to such change unless one is sure he/she is working on what’s really<br />
constraining the system because it is as <strong>si</strong>mple as that to acknowledge the fact that working on nonconstraints is time<br />
199
consuming and requires an allocation of precious resources. Therefore, there is a need for more that educated<br />
guesses; it takes theoretical understanding, experience, evidence, and cause-and-effect logic.<br />

nd edition,<br />
In order to better understand how the principles of the Theory of Constraints work and how its instruments<br />
can be applied to identify and break policy constraints, we propose the following case study: reformulating the<br />
200
measurement system for evaluating the production performance of the operators on the production line in a manner<br />
con<strong>si</strong>stent with the goal of the company. As a reference point for the further analy<strong>si</strong>s, a product flow diagram is<br />
supplied. It describes the flow of parts from one operation to the next and the equipments necessary to process them<br />
in order to make up the final product. (Fig.1)<br />
As an example, during the manufacturing process various unde<strong>si</strong>rable effects may arise, such as:<br />
1. Equipment E3 receives mismatch parts from E4.<br />
2. Sales orders are frequently shipped late for the product.<br />
3. Equipment E2 often incurs gaps in the buffer because of the late orders for parts P1.<br />
4. There are gaps in the shipping buffer for the product.<br />
These previously defined unde<strong>si</strong>rable effects are to be found in Fig.1. In Fig.2 the current reality tree is<br />
created based on the assumptions above mentioned. The core cause identified for generating the late orders is “E4<br />
combines lots to maximize productivity and save setup”. The issue now becomes understanding why setup savings<br />
are performed at equipment E4. The answer is given in the same figure: operators usually act on how they are<br />
measured and they are concerned about making their equipments as efficient and as productive as pos<strong>si</strong>ble; their<br />
actions will consequently regard saving time at E4, which is seen as a measure of increa<strong>si</strong>ng productivity. So the core<br />
cause is actually a policy constraint: the operators are measured inappropriately, which is a managerial constraint.<br />
3.2 The conflict resolution diagram (what to change to)<br />
It is also known under the name of the “evaporating cloud” (Detmerr, 1998, p.103) and was de<strong>si</strong>gned to<br />
resolve the hidden conflicts that usually perpetuate chronic problems. The conflict resolution diagram (CRD) is built<br />
on the idea that most core problems exist because some underlying conflict prevents solution of the problem. This<br />
diagram could be seen as a creative engine that allows managers to invent new, breakthrough solutions to such<br />
unpleasant <strong>si</strong>tuations. Consequently, the CRD provides the first part of the answer in determining what to change to.<br />
The CRD includes the objective of the organizational system, the necessary-but-not-sufficient requirements<br />
that lead to it, and the prerequi<strong>si</strong>te – usually the outward indications of the conflict – needed to satisfy them. The<br />
CRD is intended to achieve the following purposes: to confirm that the conflict actually exists, to identify the conflict<br />
that perpetuates a major problem, to identify all assumptions underlying the problems and conflicting relationships,<br />
to explain in depth why a problem exists, to create solutions in which both <strong>si</strong>des win, to create new, breakthrough<br />
solutions to problems, to resolve the conflict by avoiding compromise at the same time.<br />
The key to resolving the conflict lies in the assumptions – sometimes subconscious – that could be made<br />
about the relationship between the necessary conditions, the requirements and the prerequi<strong>si</strong>tes that must be fulfilled<br />
in order to satisfy them.<br />
Figure 3 reveals operator’s contradiction. The objective in this <strong>si</strong>tuation is to increase the return on<br />
investment, as this is the purpose of each company that seeks for efficiency from the financial perspective. In order<br />
to increase the return on investment (throughput) the requirement is to increase productivity of E4 and to exploit E2.<br />
In order to increase productivity, there is a prerequi<strong>si</strong>te that should be con<strong>si</strong>dered, namely reducing the number of<br />
setups. Regarding the other requirement, exploiting E2, it is fulfilled only if E4 produces according to the schedule.<br />
But operators at E4 cannot respect the schedule while reducing setups. Therefore they are faced with a conflicting<br />
<strong>si</strong>tuation – two events that are mutually exclu<strong>si</strong>ve.<br />
OBJECTIVE<br />
Increase throughput<br />
REQUIREMENT 1<br />
Exploit E2<br />

3.3 The future reality tree (what to change to)<br />
The future reality tree (FRT) was developed as a means to model the changes after defining the<br />
breakthrough solution from the CRD. The concept behind it is relatively <strong>si</strong>mple. First of all, it all starts with<br />
injections – the changes that are to be initiated. To those, elements of existing reality are added, producing new<br />
effects not currently existing. To the new effects, other injections are added as required to advance the chain of cause<br />
and effect progres<strong>si</strong>vely toward the ultimate objective – the de<strong>si</strong>red effects. As the future reality tree is developed,<br />
the answers to two very important questions about the proposed idea are to be revealed: first, will it really get things<br />
closer to the de<strong>si</strong>red effects or are they to mill around aimlessly? Second, what are the weaknesses of the ba<strong>si</strong>c idea?<br />
In other words, what additional changes (injections) will be required to sustain progress toward the de<strong>si</strong>red effect?<br />
Knowing the answer to the first tells whether the idea is worth continuing with in the first place. Knowing the answer<br />
to the second provides some idea of the other factors needed to be con<strong>si</strong>dered to make the ba<strong>si</strong>c idea work.<br />

The FRT is actually ea<strong>si</strong>er to build than the CRT. First, when building the current reality tree, there is<br />
nothing but the unde<strong>si</strong>rable effects that come out, to build a detailed picture of existing reality. The previously<br />
202
constructed CRT gives a fairly clear picture of the existing reality and its interdependencies. And after all, almost<br />
anything is ea<strong>si</strong>er to be built when having the important building blocks in place to start with. Already having the<br />
unde<strong>si</strong>rable effects from the CRT, the de<strong>si</strong>red effects are no more than the diametric oppo<strong>si</strong>te of those and by<br />
rever<strong>si</strong>ng them, the top of the future reality tree is clearly pictured. Other elements of the FRT are to be taken from<br />
the conflict resolution diagram, such as the objective of the system and at least one requirement. Thus, building the<br />
tree becomes an exercise of interpolation – filling in the gaps between established milestones – which is why the<br />
FRT usually comes together much more quickly.<br />
In order to solve the conflict that the operators at the production line are struggling with an injection is<br />
introduced: the introduction of a new measurement system for the performance of the operators, the Throughput<br />
Dollar Days, which will determine the operator focus more on delivering parts according to the schedule for E2.<br />
(Fig.4)<br />
3.4 The prerequi<strong>si</strong>te tree (how to execute)<br />
The prerequi<strong>si</strong>te tree (PRT) helps to execute the deci<strong>si</strong>on. It identifies the obstacles that might keep the<br />
devoted manager from doing what he/she wants to do and helps determine the best ways to complete the major<br />
milestones in implementing the deci<strong>si</strong>on. The PRT provides the first half of the answer to the last question how to<br />
change.<br />
What are the minimum requirements for successful change? The recipe is fairly <strong>si</strong>mple:<br />
1. Identifying and deciding how to overcome obstacles to implementation.<br />
2. Laying out an effective step by step plan for execution, including accountabilities and measures of success.<br />
3. Acting with determination and perseverance to execute the plan, this being purely a leadership function.<br />
Neither the principle nor the tools of the theory of constraints, or any other methodology, can substitute for<br />
the will to see the job done. But TOC tools, especially the thinking process, can be particularly useful in the first two<br />
requirements. The prerequi<strong>si</strong>te tree was specifically de<strong>si</strong>gned to help identify and overcome the obstacles to effective<br />
change.<br />
The prerequi<strong>si</strong>te tree has only three kinds of elements: an ultimate objective, obstacles, and intermediate<br />
objectives. There is only one objective. It’s the deliverable of the effort – a completed project or executed change –<br />
and it re<strong>si</strong>des at the very top of the PRT.<br />
OBSTACLE<br />
Operator does not understand the<br />
measurement process based on<br />
throughput calculation<br />
OBSTACLE<br />
There are no appropriate tools to<br />
support the new measurement<br />
system<br />

This is an example of tree that can be very well built in a small group because some degree of creativity is<br />
necessary to discover all pos<strong>si</strong>ble obstacles of the implementation of the change and to enumerate them. A <strong>si</strong>ngle<br />
person might not see the tree from the forest, but working together is very likely to produce a complete list of<br />
obstacles.<br />
Figure 5 presents the pos<strong>si</strong>ble obstacles that may arise impeding the action described by the injection and<br />
the intermediate objectives that can be used to overcome these obstacles.<br />
3.5 The tran<strong>si</strong>tion tree (how to cause the change)<br />
It happens frequently that great ideas remain only ideas. The effective execution that turns them into<br />
solutions never occurs. As previously stated, clearing objectives is definitely important, but not enough by itself to<br />
guarantee success. At the strategic level, it’s sufficient to establish what must be accomplished and when it should<br />
happen in a general way at the system level. A strategic plan usually addresses large-scale goals, such as opening a<br />
new market, completing a merger or acqui<strong>si</strong>tion, or developing a new product line. It might also establish the time<br />
horizon for these achievements and who has respon<strong>si</strong>bilities for them. Armed with such a plan, individuals or groups<br />
usually know what’s expected of them, though they might not always have a big picture or know precisely why they<br />
are doing what they are.<br />
The last of the ba<strong>si</strong>c five tools, the tran<strong>si</strong>tion tree (TT) helps develop the detailed step-by-step instructions<br />
for implementing the chosen course of action. It also provides the rationale for each step, a critical factor in<br />
persuading people to get involved in the implementation process. It may be seen at the same time as a detailed road<br />
map to the attainment of the objective established, answering the second half of the question: how to change.<br />
The tran<strong>si</strong>tion tree looks very much like the future reality tree. It is in fact a type of FRT, because it contains<br />
a series of causes and effects that do not exist yet, injections that must be accomplished, but which are more concrete<br />
than those in the future reality tree. And these differences between the two trees appear due to the fact that their<br />
purposes differ <strong>si</strong>gnificantly. The FRT is built for test and validation, whereas the TT is built with the purpose to<br />
implement the ideas tested previously.<br />
Constructing a tran<strong>si</strong>tion tree is <strong>si</strong>milar to building a future reality tree, starting at the bottom with an initial<br />
action, and building upward toward a predetermined objective. But the process begins with some elements already in<br />
place, <strong>si</strong>nce the objective and the intermediate objectives from the prerequi<strong>si</strong>te tree are put together in this new tree.<br />

4. Conclu<strong>si</strong>ons<br />
204
This paper presents a set of instruments by which to identify and eliminate policy constraints, aiming at<br />
continuously improving systems’ performance. The example of the inadequate measurement system used for<br />
evaluating the performance of the operators on the production line is very eloquent in this respect. Applying the<br />
Theory of Constraints tools to tackle the policy constraint that managers on the shop floor are dealing with represents<br />
a tremendous shift from the clas<strong>si</strong>cal approach, and it changes the way management perceives organizational systems<br />
for the future. The implementation of the TOC tools can solve an important number of policy constraints that have<br />
impeded companies to improve their performance and to continuously innovate in the past few years. Therefore<br />
future investigation could be directed towards analyzing the cases of companies that applied the principles of this<br />
theory, to see what worked or did not work, and how it could be adapted to different bu<strong>si</strong>ness environments. Further<br />
research regarding the application of these tools to the service sector and to other functional areas of a company such<br />
as marketing and accounting is required.<br />

I. Introduction<br />
During actual economic cri<strong>si</strong>s, both IT providers and their beneficiaries needed to review the IT strategy in order<br />
to surmount the financial loss. IT providers opted for partnerships and strategic acqui<strong>si</strong>tions to empower their<br />
product portfolio, while end-user companies rede<strong>si</strong>gned the IT investment strategy and revised undergoing IT<br />
projects’ opportunity.<br />

Con<strong>si</strong>dering the divergence between European Commis<strong>si</strong>on’s directions and financial institutions’ advice<br />
regarding companies’ po<strong>si</strong>tioning towards IT during cri<strong>si</strong>s, this paper aims to answer the question: which is the world<br />
financial cri<strong>si</strong>s impact on IT investments and which are the major changes in the European IT ?<br />
II. Strategies adopted by IT providers<br />
II.1. Acqui<strong>si</strong>tions and strategic partnerships<br />
Siemens announced by the end of April 2009 the acqui<strong>si</strong>tion of Elan bu<strong>si</strong>ness, a software provider specialized<br />
in MES (Manufacturing Execution Systems) products in Toulouse, that addresses the pharmaceutical and the<br />
biotechnical industries. This acqui<strong>si</strong>tion allows Siemens to enrich its solution portfolio on the industrial software<br />
market and strengthens the company’s anchoring in France.<br />
Present on the financial market as well as on the telecommunications market, Sun Microsystems has been<br />
profoundly affected by the cri<strong>si</strong>s and did not recover, having registered 209 billion $ loss in the last term of 2008,<br />
according to ITR MANAGER(2009,).<br />
IBM, another IT market leader, took advantage of the world economic cri<strong>si</strong>s to initiate and develop negotiations<br />
for acquiring and integrating in its structures one of the most important bu<strong>si</strong>nesses in Sillicon Valley: Sun<br />
Microsystems. The product portfolio and the technologies that this acqui<strong>si</strong>tion would have brought to IBM con<strong>si</strong>sted<br />
of a microprocessor of RISC (Reduced Instruction Set Computer) architecture, the OpenSolaris operating system and<br />
the programming language Java. The new bu<strong>si</strong>ness IBM-Sun would hold 2/3 of the Unix market, if we take into<br />
con<strong>si</strong>deration the IBM AIX and the Sun Solaris systems. Also, they would control an important market share on the<br />
servers’ market, con<strong>si</strong>dering IBM Power and Sun SPARC servers.<br />
Due to the fact that IBM underestimated Sun bu<strong>si</strong>ness, speculating its disadvantageous <strong>si</strong>tuation caused by the cri<strong>si</strong>s, Sun’s council of<br />
administration did not approve the transaction.<br />
The same strategy of acqui<strong>si</strong>tions was adopted by Oracle, who made an offer to buy Sun’s actions, as reported<br />
by Rafal, Olivier (2009). The transaction was approved by Sun’s council of administration at the end of April 2009<br />
and reached the sum of 7.4 billion $; it is still in progress its approval by the stakeholders and by the authority of<br />
regulations. The benefits of the new bu<strong>si</strong>ness Oracle – Sun contain the middleware Java Fu<strong>si</strong>on and the Solaris<br />
exploitation systems for Oracle Database deployment. Thanks to this acqui<strong>si</strong>tion, Oracle surmounts IBM from the<br />
technologies offer point of view.<br />
Oracle’s acqui<strong>si</strong>tion of the Java development platform represents the premise for fulfilling clients’ demand of<br />
reduced complexity and diminished risks in u<strong>si</strong>ng Oracle products. Another benefit is the pos<strong>si</strong>bility to develop<br />
Oracle products based on standards and under open source licenses.<br />
In the web sector, the pioneer bu<strong>si</strong>ness that became the leader in micro blogging, Twitter, is the subject of recent<br />
acqui<strong>si</strong>tion negotiations by Google. Valuated at 250 million $ and con<strong>si</strong>dered an important Internet service, Twitter<br />
represents an interesting investment for Google for its real time search engine and its prestige.<br />
From this analy<strong>si</strong>s, it arises a trend of big IT companies trying to enrich their product portfolio during cri<strong>si</strong>s,<br />
aiming to enter new retail markets and to integrate new technologies that would increase the potential of their own.<br />
An Ovum study underlines the fact that fu<strong>si</strong>ons and absorptions in the networking and telecommunications<br />
sector are not always successful due to equipment integration difficulties.<br />
II.2. Sales and cutting costs strategies<br />
In order to surmount cri<strong>si</strong>s effects , the big IT providers adopt different cutting costs strategies. A rigorous<br />
evaluation of the bu<strong>si</strong>ness is carried out in order to identify and remove unprofitable activities.<br />
Oracle, database leader, sold OnTarget, its former consultancy divi<strong>si</strong>on specialized in Siebel products.This<br />
bu<strong>si</strong>ness had been acquired by Oracle in 1999 for 259million euro.<br />
A company that has been profoundly affected by the economic cri<strong>si</strong>s is Microsoft , as reported by Lambel,F.<br />
(2009) . Microsoft registered loss in its main operating fields, for the first time in 23 years of existence. The online<br />
service divi<strong>si</strong>on experienced a decrease of 14.5% during the first term of 2009. The divi<strong>si</strong>on of peripherals and media<br />
encountered a decrease of 1.6% in revenues, while the individual operating systems divi<strong>si</strong>on encountered a decrease<br />
of 15% in revenues in the same period. Simultaneously, the Microsoft ERP divi<strong>si</strong>on ,Dynamics, registered a decrease<br />
of 5% in revenues in the first term of 2009.<br />
According to market research carried out by Microsoft , the general trend on the IT market is customers shift<br />
towards cheaper products. To defeat sales loss , Microsoft had to reduce Windows license prices and to approve<br />
207
Windows XP installation on laptops, in damage to Windows Vista , in order to counteract Linux offen<strong>si</strong>ve, as related<br />
by Nemec-Poncik M. (2008).<br />
On the other hand, Microsoft cutting costs strategy includes: reducing spending in low-priority fields, reducing<br />
marketing campaigns for Windows Vista, decrea<strong>si</strong>ng investments in data-centers, slowing the recruitment process<br />
with 15% and reviewing mobility costs for the own employees.<br />
SAP, the German IT ERP solutions provider, encountered 33% sales loss in the first term of 2009 compared to<br />
the same term of 2008, as reported by Gros Maryse (2009). Still, SAP’s world revenues decreased by only 3% during<br />
this period , thanks to the application maintenance divi<strong>si</strong>on. The support services price increase from 17% to 22% of<br />
the license’s value , could be staggered till 2015, depending on a measurement system that would evaluate the ERP<br />
solution’s contribution to the client bu<strong>si</strong>ness. Simultaneously, in January 2009 , SAP announced a personnel dismiss<br />
of 3000 jobs out of the total 50500 employees, of which 1900 employees already left the company in the US and UK<br />
and shifted towards other jobs.<br />
Economic agents’ behavior and IT budget<br />
A study carried out by Celent ,¦���¤��£��£��£�©��£©¨�¤¢�£�¤��©�¨��©¨�¤¢��¤��£�¤������,predicts that IT<br />
investments will reach a total amount of 353.3 billion $ in 2009 among financial institutions, which represents a<br />
1.3% decrease compared to 2008. This prediction is a rupture in the general trend of increase in IT investments<br />
during the last years: a 6.4% increase during 2007 and a 4.5% increase in 2008. Still, the study predicts that, in 2010,<br />
IT spending on specific products and services in the financial sector will register an increase up to the value of 364.5<br />
billion $ (figure 1).<br />

Figure 1. IT investments evolution in the financial sector, according to the Celent study<br />
Out of the total amount of IT investments during 2008, 71.9% addressed IT maintenance and this important<br />
percentage will be maintained during the following years as the financial cri<strong>si</strong>s reduces the value of new investments.<br />
Another <strong>si</strong>gnificant trend is the increase of the founds allocated for IT insurance, currently estimated at 105<br />
billion $ in 2009, 1% higher than in 2008.<br />
The Celent study concludes that in 2009, due to the financial cri<strong>si</strong>s, IT spending will diminish to the value of<br />
31.8 billion $ in North America, respectively to the value of 24.8 billion $ in Europe. The corresponding decreases<br />
compared to 2008 are 12.4% in North America, respectively 5% in Europe.<br />
Due to the fact that companies will need to readjust the costs, IT spending will become a source of bu<strong>si</strong>ness<br />
efficiency through an inten<strong>si</strong>ve usage. The need for productivity will maintain IT investments in the operational<br />
fields, outsourcing the non-operational IT services. From the IT acqui<strong>si</strong>tions perspective, the main differential factors<br />
in 2009 will be the prices and the financing opportunities. Reorganizations will determine the abandon of<br />
unnecessary projects.<br />
The SOA (Service Oriented Architecture) and the resource virtualization strategies will become the main<br />
methods for cutting costs. IT services will register high price pressures and will need well-founded acqui<strong>si</strong>tion<br />
justification. Outsourcing will became a mid-term opportunity.<br />

III.1 IT sectors have been affected differently by the economic cri<strong>si</strong>s<br />
For the first time after many years, in 2008 it was registered a decrease in the volume and in the value of the<br />
printers market , as reported on the web<strong>si</strong>te ITR MANAGER.COM (2009,). Laser printers<br />
registered a loss of 6% in sales, while inkjet printers registered 9% loss in sales during 2008. In France, the printers<br />
market decreased from 2.57 billon $ in 2007 to the value of 2.44 billion $ in 2008.<br />
Because almost all of the enterprises and about 2/3 of home consumers in France are equipped with printing<br />
solutions, actual printers acqui<strong>si</strong>tions address in 80% of cases replacement and modernization issues. For this<br />
purpose, Lexmark adopted the strategy of increa<strong>si</strong>ng client loyalty, by keeping prices at the quality level of their<br />
products and to the brand prestige. The differentiation strategy adopted by Lexmark is based on the concept of Green<br />
IT, laser cartridge recycling ,promoting their belief that printing quality is more important than printing quantity.<br />
According to an Idate study, it is expected that the economic cri<strong>si</strong>s would reduce investments in network<br />
exploitation along with the deployment of future Internet on optical fiber. Even so, networking providers must<br />
continue their investments in service reliability and security.<br />
The Bouygues Group estimates that the right approach that could protect telecommunications providers from the<br />
financial cri<strong>si</strong>s effects re<strong>si</strong>des in diver<strong>si</strong>fications, exploiting foreign networks and consultancy services for<br />
connecting client companies to international networks.<br />
A field less affected by the cri<strong>si</strong>s is the mobile communications, which are expected to grow with 6.3% in 2009<br />
compared to 2008, con<strong>si</strong>dering the total number of connections and the revenues.<br />
At the oppo<strong>si</strong>te pole we can find the component providers that registered a 10% decrease in sales in the last three<br />
months of 2008. Companies of this IT branch face the cri<strong>si</strong>s effects differently: while small entrepreneurship must<br />
decrease their bu<strong>si</strong>ness, big companies take advantage of this conjuncture to increase their advance to the market<br />
competitors. An important factor that allows IT companies to surmount the effect of the sales decrease is their<br />
financial reserves. The component providers that will re<strong>si</strong>st cri<strong>si</strong>s are aware of their importance for the further<br />
development of digital economy.<br />
III.2. IT role shift within company<br />
During cri<strong>si</strong>s, information system managers become the innovation drivers and a source of economic growth for<br />
the enterprise. Information systems face two phenomena nowadays: on one hand it is the rupture in operational<br />
models for accelerating change and on the other hand it is the rupture caused by the Internet and the mobile<br />
technologies. IT managers have now the opportunity to place IT near the operational branches as an activity that<br />
creates values for the company, according to ITR MANAGER (2009, < www.itrmanager.com>). In order to change<br />
the place of IT within the enterprise, IT managers should leave their role of managing an auxiliary company function<br />
mainly concerned about costs, and should approach an innovation leader’s vi<strong>si</strong>on.<br />
According to a study carried out by the Resources Global Profes<strong>si</strong>onals, 37% of IT managers drawn priorities<br />
and allocated budgets for IT for 2009 <strong>si</strong>milar to 2008. Another relevant trend indicates a decrease of investments in<br />
ERP (Enterprise Resource Planning) solutions, accompanied by a harden of project selection criteria. Shared services<br />
will continue to play an important role among priorities, while outsourcing will not.<br />
The economic cri<strong>si</strong>s may be a favorable circumstance for IT to become the main innovation factor within the<br />
enterprise. IT can demonstrate deci<strong>si</strong>on makers how to improve customer loyalty by creating a collaborative platform<br />
with them in order to define the products they wish.<br />
Also, during economic cri<strong>si</strong>s, IT can get rid of its status of costs generator obtained due to the failure of many IT<br />
projects that raised mistrust among company managers.<br />
This reorganization needs to substantially modify information systems objectives and offer them a foundation<br />
severely supervised. From this point of view, the cri<strong>si</strong>s has a po<strong>si</strong>tive effect because it accelerates the change process.<br />
III.3. The economic cri<strong>si</strong>s impact on IT labor<br />
Due to the economic cri<strong>si</strong>s, the labor offer diminished in the IT sector. An example is Cisco, a networking and<br />
communications company, which fired 2678 employees in October 2008. At the same time, the company’s jobs offer<br />
decreased from 1830 to 128.<br />
According to a study carried out by Skills Survey in 2008, the last years suffered a lack in IT experts. This<br />
conclu<strong>si</strong>on resulted from the number of IT vacancies within companies. The economic cri<strong>si</strong>s dims the recruitment<br />
209
cri<strong>si</strong>s brought by expert mobility. The fields that are most affected by the lack of IT personnel are: the programming<br />
languages (C, Java, Visual Ba<strong>si</strong>c), Internet services (SOA, .Net, J2EE), networks and system administration.<br />
From the IT managers’ perspective, a study carried out by CIO Connect predicts their involvement in company’s<br />
reorganization. IT experts obtain a key role in the company’s commercial relationships and in projects’ startup,<br />
thanks to their profound knowledge of the bu<strong>si</strong>ness.<br />
As they come from a dynamic field, affected by continuous changes, IT managers can<br />
efficiently implement the organizational change strategies within the enterprise by aligning it to<br />
the new trends of resource virtualization and “cloud computing”.<br />
IV. European Commis<strong>si</strong>on’s and banking institutions’ recommended strategies<br />
Due to the high price pressures, IT solution providers will need to develop strong centralized corporative<br />
bu<strong>si</strong>ness relationships because deci<strong>si</strong>ons move their center from the local divi<strong>si</strong>ons towards the central company.<br />
Also sophisticated technical and functional features will loose importance when compared to the portability,<br />
architectural integrability and price.<br />
Small IT providers need to align their bu<strong>si</strong>ness with the big IT infrastructure providers and to the big<br />
outsourcers.<br />
The companies that will recover faster after the economic cri<strong>si</strong>s will be the ones that adapted, experimented and<br />
implemented new technologies, thus obtaining a <strong>si</strong>gnificant advance in the competitive environment.<br />
According to the European Commis<strong>si</strong>on communicate addressed to the European Parliament in 20.07.2005, �£�����¢��¢©��¤¦������������§(2005),the EU<br />
IT strategy contained to main spending programs for the following period 2007-2013:<br />
- the seventh framework for research, technical development and demonstration (RTD) that addressed<br />
excellence promotion, knowledge and researchers’ free mobility, R&D regional clusters promotion. This framework<br />
represents a large scale approach to the public-private partnership for technological initiatives’ implementation (such<br />
as nanoelectronics, embedded systems)<br />
- the framework for competitiveness and innovation ��¤����§�£� �¤�� ���������£�����¢�¢�¡��©�����¨�<br />
The “ i2010- an information European society for economic growth and jobs” initiative aimed to support<br />
technologies usage and production as a key factor for economic and social development.<br />
According to Acad. Filip F.G. (2005,pp 33-34), priorities of the “i2010” initiative referred to:<br />
- establishing a framework for IT market management : telecommunication frequency spectrum<br />
control, laws for electronic commerce, providing security in the information society.<br />
- an increase of investments in IT research with up to 80% in order to reduce the difference from USA,<br />
Japan and China<br />
- implementing the digital economy elements in the social life through e-government services, einclu<strong>si</strong>on<br />
and digital culture<br />
On 20.04.2009, in Brussels, “the ICT boundaries movement ”[2] was presented as a new strategy for future<br />
research and technology improvement in Europe.<br />
focuses �§¢��¤������ ��¢¢¤�¤©¢�����§�§¢¤©��¤�¤¢�£���¤����¨��£¤�£�<br />
The document<br />
on the research strategy in the field of new technologies and FET (Future and Emerging<br />
Technologies). The European Commis<strong>si</strong>on elaborated this document in times of economic cri<strong>si</strong>s, as a solution for<br />
companies to surmount it through investments in innovation for the future. It comes underlined the multidisciplinary<br />
and collaborative approach, where recent discoveries in biologic systems with automatic organization should be<br />
included in IT projects. Although this approach meets high risks, the document opposes them the potential high<br />
revenues and the chance of revolutionary innovations.<br />
This strategy recommends that companies should focus on research and innovation in order to increase the ICT<br />
European industry competitiveness on a long term. Fields like quantum informatics, novel systems, IT systems<br />
inspired from neurology, bi-directional brain-machine interfaces, collective intelligence, represent projects supported<br />
by the FET strategy, bringing Europe the leader po<strong>si</strong>tion in this research fields.<br />
��£����¤¦���¢���£¤¢��©��¢©�¤�<br />
210
In an economic cri<strong>si</strong>s context, companies tend to take cautious action, to develop in-house investments and<br />
priority research focused on short-time market needs. In order to defeat this trend that could slow the innovation<br />
process, the European Commis<strong>si</strong>on recommends important investments both in public and private environment in<br />
high risk research, presenting the benefits that could be obtained in the future.<br />
Compared to the document of 2005, from the researchers’ perspective, the focus changes from the mobility<br />
pos<strong>si</strong>bilities towards their freedom to explore unconventional new ideas and novel approaches. If research undergoes<br />
radical change process, supported by the involvement of the bu<strong>si</strong>ness actors, European ICT will be able to take<br />
advantage of the new market opportunities once the economic cri<strong>si</strong>s is over.<br />
The collaborative <strong>si</strong>de within IT research is justified by the actual research framework, whose strong<br />
fragmentation led to efforts’ replication, priorities’ divergence and opportunities underutilization. In order to achieve<br />
this goal the European Commis<strong>si</strong>on suggests common research agendas based on shared vi<strong>si</strong>on “Joint Technology<br />
Initiatives”. The failure probability of ITC research projects can be reduced through the partnership between<br />
academia and bu<strong>si</strong>ness environment, along with frequent dissemination of FET projects aiming to reduce the gap<br />
between research directions and their applicability.<br />
A special place within the framework belongs to the small and medium enterprises (SMEs), who should be<br />
helped to surmount the cri<strong>si</strong>s as they represent the main beneficiary of the research results, according to the European<br />
Commis<strong>si</strong>on. Those SMEs whose activity is driven by an inten<strong>si</strong>ve valuation of research products should be the first<br />
supported because they can convert early research results into successful industrial stories.<br />
Another important aspect underlined by the European Commis<strong>si</strong>on refers to the free sharing of results and<br />
scientific knowledge. From the IT perspective, this recommendation can be materialized through standards<br />
implementation and open source products.<br />
The European Council is permanently preoccupied with IT evolution during cri<strong>si</strong>s, so that its working agenda<br />
systematically contains aspects regarding the IT strategy. All of the member states adhered to the long term solution<br />
that implies the development of new technologies’ market, inten<strong>si</strong>fying research and innovation, satellite-solutions<br />
for the rural area. The European economic recovery plan includes large scale Internet projects of 5 billion euros,<br />
allocated for both improving the existing IT infrastructure and for extending it in the rural areas.<br />
In order to support the high risk research, the European Commis<strong>si</strong>on suggested doubling investments in this<br />
field until 2015, both at a national level and in the EU. Even if the European Union provides a third of the world<br />
scientific knowledge base, the IT research receives only a quarter of the world financing founds, according to<br />
PublicTechnology.net ( 2009, < www.publictechnology.net> ).<br />
The European Commis<strong>si</strong>on especially indicated the following research fields: the development of fault tolerant<br />
systems that copies the human brain processes for coping with hardware failures, proces<strong>si</strong>ng power faster than the<br />
light speed that is able to process unlimited quantities of data of petabyte <strong>si</strong>ze ( 1 petabyte=1000 terrabyte).<br />
Outstanding research results in high risk IT projects were awarded Nobel prizes : Albert Fert (France, 2007),<br />
Peter Grunberg (Germany, 2007), Theodor Hansch (Germany, 2005).<br />
The European Commis<strong>si</strong>on concluded that the new generation of IT systems should not be built in a top-down<br />
“great vi<strong>si</strong>ons” approach, because the financial collapse demonstrated the vulnerability of not mature complex<br />
systems. It is preferable an organic development of technologies, supervised by both researchers, big companies and<br />
SMEs in a collaborative environment.<br />
Regarding the IT budget allocation, banks’ recommendation suggests that companies should not carry out a<br />
strong savings policy and that firms should focus to identify those technological niches to help overcome the actual<br />
difficulties. Contrary to the European Commis<strong>si</strong>on’s recommendations, banks suggest firms to invest in productive<br />
ICT products that are profitable on a short term. Banks counsel their client companies not spending IT budgets on<br />
technologies that have not yet reached maturity or that they do not master.<br />
Along with high-risk innovative research promotion, the IT strategy de<strong>si</strong>gned by the European Commis<strong>si</strong>on<br />
includes a shift in the IT investments from the telecommunications field towards software, as reported by Nemec-<br />
Poncik, M. (2009).<br />
Telecommunications have been con<strong>si</strong>dered a priority until late due to their high revenues and jobs offer , but<br />
now the IT infrastructure needs to be exploited by an adequate and inten<strong>si</strong>ve software usage.<br />
The Commissar for the information society Viviane Reding , appreciates that software impact is at least as<br />
important as that of telecommunications from the usability point of view. After a projects contest , the group formed<br />
by the institutes : Idate (France), Institut Fraunhofer ISI (CNRS Germany), London Economics (UK) became the<br />
coordinator for a project that aims to promote software and IT services in Europe for a total amount of 424600 euro<br />
during 15 months.<br />
The group will be coordinated by <strong>IN</strong>FSO (Information society and media) and the European Commis<strong>si</strong>on.<br />
The goals of this research consortium include:<br />
211
-European IT actors mapping<br />
-defining a set of IT regulations<br />
-<strong>si</strong>mulating scenarios for European software development incentives<br />
The project’s agenda includes meetings with the main IT actors :<br />
-developers ( including license vendors and maintenance providers)<br />
-IT associated service societies (like Internet service providers)<br />
-new services (outsourcing, data-centers, cloud-computing, Software-as-a-Service)<br />
-online adverti<strong>si</strong>ng web<strong>si</strong>tes (Google)<br />
-profes<strong>si</strong>onal associations, public institutions, end-users, financial specialists<br />
In order to fulfill program objectives, the group will include elements like financing facilities, research<br />
encouraging , SMEs’ notification of the pos<strong>si</strong>ble benefits brought by an adequate IT equipping , in<strong>si</strong>de its software<br />
promoting project.<br />
Conclu<strong>si</strong>ons<br />
The present study enlightens the major changes and the major IT directions supported by the European Union<br />
for the next years.<br />
This research can become a guide for those Romanian companies that aim developing IT projects by acces<strong>si</strong>ng<br />
European founds for financing , as well as for the Romanian IT market actors that need to align to the European<br />
trends in this field.<br />
This study might be developed in the future , by con<strong>si</strong>dering the findings of the European IT consortium<br />
research in software development and, also , by con<strong>si</strong>dering the results of those directions that the European<br />
Commis<strong>si</strong>on recommends within its innovation strategy.<br />

Resolving interdepartmental contradiction between production and<br />
marketing<br />
Ilinca Hotăran<br />
as<strong>si</strong>stant professor, PhD economics, Academy of Economic Studies, Bucharest, Romania,<br />
ilincahotaran@yahoo.com<br />
(Drucker, � ¢¤©¨£� �¤�<br />
Peter Drucker used to say:<br />
F. Peter 2006). The article is based on a fact: there are many concepts, generally con<strong>si</strong>dered<br />
valid, adopted without being studied, that stay valid because of inertia, but their results can be dramatic.<br />
The article highlights the perception of people about the interdependence between the departments of<br />
production and marketing, which are regarded as components of any company. We realize that we are continuously<br />
maintaining an incorrect relationship, and this may have adverse effects. The practical problem presented in the<br />
article identifies a preconception: the production department must execute what is ordered by the department of<br />
marketing, the demand resulting from the market research conducted. This article suggests, first, a generic problem<br />
solving of resource allocation (mix of production) and on the other hand, the correction of the payment system,<br />
which would harmonize the work of both departments. After presenting and analyzing several views, resulted from a<br />
questionnaire, and after we conduct a numerical analy<strong>si</strong>s based on solving the problem presented, we can illustrate<br />
the proper relationship between the two departments. This relationship is necessary in order to support company<br />
objectives.<br />
�£�¤����§¢�§¨¤��¤©¢¤�©��¤¢�§���§���¤�£��¤���©��¤¢£���¤�¤���©�£����<br />
Keywords:<br />
Production, marketing, interdependence, remuneration system<br />
In the context of a global economic cri<strong>si</strong>s in full momentum, all areas try to solve problems. What is in fact<br />
the most affected segment? This segment is composed of units of production and market. What to do when the<br />
people produce can not sell to the market? What to do when we offer something that the market no longer wants to<br />
buy or no longer afford? If until now its have been accepted and validated a number of erroneous concepts, now is<br />
the time when all of them should be reviewed and should be offered solutions. The relationship between the<br />
department of production and marketing is erroneously understood, as I demonstrate in the following study. This<br />
theory was false but passed from generation to generation until it was imposed as it’s true.<br />
Marketers have a very important role, but can not do this alone, and they must know how to maintain good<br />
relations with partners in<strong>si</strong>de and out<strong>si</strong>de the company, working together to enter in connection with customers<br />
(Philip Kotler Gary Armstrong 2008). Without interdependence between departments and without communication<br />
and an effective system of remuneration, the success of organizations is compromised.<br />
How do we know when it needs changing and what to do in order to not follow the path which goes to this?<br />
It’s easy: when you have a runny nose, you know that you are <strong>si</strong>ck and you need aspirin. Unfortunately, we already<br />
have a cold – you are in the middle of the phenomenon and you must exceed it fast, with costs as low as pos<strong>si</strong>ble and<br />
follows as less serious as pos<strong>si</strong>ble. It's important to know what caused disorder, in order that the next time to avoid it.<br />
Not to be de<strong>si</strong>red, sometimes happens that a nose that runs to be a <strong>si</strong>gn of old diseases, a chronic disease a deep body<br />
malfunctions. Also in the case of bankruptcy of an organization, we can find a reason an ineffective remuneration as<br />
a result of misunderstanding of the interdepartmental –relationship<br />
I conducted a market study con<strong>si</strong>sting of a segment of 50 subjects, who where directed the following<br />
question: "what is the link between production department and marketing department, in your opinion?” Responses<br />
may be included in the same sphere of explanations, as shown in Figure 1.<br />

Figure 1 Research 1.<br />
Responses were as follows:<br />
1. 46% of subjects responded in different forms of expres<strong>si</strong>on, the idea that "Marketers should promote and<br />
sell what is produced in the department of production”<br />
2. 33% believed that "There is a relationship in the double sense: Marketing provides market information,<br />
the producer analyzes the demand, and then the marketer promotes the offer"<br />
3. 9% offered other <strong>si</strong>milar answers<br />
4. 7% of subjects con<strong>si</strong>dered that "the manufacturer must fulfill with market demand”<br />
5. only 5% believe that "Marketer's must realize which is the best sold product, and must request its<br />
production"<br />
The second case study provided responses to the question: "What is the main element that should be taken<br />
into account in the setting of remuneration of marketing department?" (Figure 2).<br />
21%<br />
9%<br />
Figure 2 Research 2<br />
Results can be clas<strong>si</strong>fied as follows:<br />
1. 70% of subjects con<strong>si</strong>dered that the best paid should be "Those who sell the highest quantity of<br />
production”, so that the system of remuneration must be reported as a selling percentage<br />
2. 21% believe that the best paid must be "Those who identify the best the market demand"<br />
3. only 9% believe that the most important is to pay "Those who promote and sell the more expen<strong>si</strong>ve<br />
products and make a maximum profit"<br />
Following the analy<strong>si</strong>s conducted on these responses, we found that the general opinion is that an effective<br />
marketer is that one which provides a more clear picture of the market, and then sells the most requested products.<br />
In the context of economic cri<strong>si</strong>s, a good entrepreneur must know first how to remunerate his employees.<br />
Behavior is very strongly influenced by the manner in which their work is measured. The measurement of quality of<br />
an activity is a segment difficult to explore, and an ineffective measurement system can produce only damage. So<br />
what is the <strong>si</strong>tuation in present? Almost all managers of production department remunerate the marketing department<br />
depending on the quantity sold. Interest is clearly going to sell those products more expen<strong>si</strong>ve in order to accumulate<br />
the largest amounts, and receive a high percentage. It is an inefficient thinking, is a concept that can bring the<br />

company on the verge of a bankruptcy. If the marketing department sells the most expen<strong>si</strong>ve products, and record<br />
high revenue, why can still be inefficient for the company?<br />
In order to demonstrate the set, I took a <strong>si</strong>mple numerical example:<br />

20$ /unit<br />
This scheme shows the activity of an organization that sells two products: P and Q. The product P is sold by<br />
90$/ unit and can be produced in a quantity of 100 units/ week, while Q is worth 100$/ unit and can be produced in a<br />
quantity of 50 units/ week. After that, we can see the time needed by each resource. We must note that we need<br />
resources RM1, RM2 and RM3, which is worth 20$, and we also need one resource that cost extra 5$.<br />
We must also know that there is a <strong>si</strong>ngle resource A, B, C and D, and that each can be used only<br />
2400minutes/ week.<br />
We must offer the perfect production that assures the maximum profit.<br />
At first glance, if we trust the marketer to calculate what is effective to sell, he will make a <strong>si</strong>mple<br />
calculation based on the profit and cost of each product.<br />
There are two <strong>si</strong>tuations. In the first ver<strong>si</strong>on, he decided to sell the Q because it is more expen<strong>si</strong>ve and<br />
therefore earnings will be higher. In the second <strong>si</strong>tuation, he calculates the profit margin for each product. This is<br />
calculated by subtracting the costs from the price.<br />
For the Q = 100 $ -20 $ -20 $ = 60 $<br />
For the P = 90 $ -5 $ -20 $ -20 $ = 45 $<br />
Hence, it will conclude that it is more efficient to produce and sell in the first place all the Q.<br />
Continuing the calculations, suppose that we decided to produce 50 Q and P, and calculate the return. A sale<br />
of 50 products Q, records revenue of 50*60 $ = 3000$. After we produce 50Q, we see that due to limited capacity of<br />
resources we can produce only a few P. To produce 50 Q, resource B was used 50unit * 30min = 1500min.<br />
Maximum capacity is 2400 minute. It appears that we can use this resource for 900minute, sufficient to produce<br />

900min/15min = 60 units of product P. It follows that we have a profit of $ 3000 + 60unit * 45 $ = 5700$. If we<br />
follow this deci<strong>si</strong>on of selling, after we reduce the operational costs, we conclude the month with loss of 300$.<br />
It's effective to leave the selling deci<strong>si</strong>on to the marketing department? It's effective to sell what they ask<br />
us? It is effective that the best paid employees are those who sell the most value? To answer these questions, we will<br />
try to approach this issue through the production department.<br />
The first calculation that will make a worker in the production department will be to calculate the narrow<br />
place, the place for which demand is greater than it can provide. Thus, they calculate the minutes needed to produce<br />
the two products in the maximum and they observe that the resource B exceeds its capacity of 2400 minutes:<br />
resource A= 15min*100unit P +10min *50unit Q= 2000min<br />
resource B= 15min*100unit P + (15min+15min) *50unit Q= 3000min<br />
resource C= (12min+8min)*100unit P +8min *50unit Q= 2400min<br />
resource D= 15min*100unit P +7min *50unit Q= 1850min<br />
Knowing which is the narrow place, in order to establish the most appropriate production mix, the<br />
department will first calculate the yield of the narrow place. Thus, resource B efficiency through product P = 45 $<br />
(profit margin) / 15min (minutes necessary of resource B) = 3 $ / minute. Resource B efficiency through product Q is<br />
= 60 $ / 30min = 2$ per minute. From here we deduce that it is more profitable to produce the P, and not the product<br />
Q as it appear at first observation.<br />
A staff of production department will determine that it will sell the entire quantity of the product P.<br />
Following this production, it will remain available 900 minutes of resource B. This ensures the production of 30<br />
products Q. So, the production mix most effective is composed of 100 units P and 30 units Q.<br />
This problem of determining the mix of production through the narrow place is actually a linear<br />
programming problem, which can be ea<strong>si</strong>ly solved by introducing con<strong>si</strong>stent data and variables and solving them<br />
u<strong>si</strong>ng the solver in Microsoft Office Excel.<br />

organizaŃie, activitatea se dovedeşte ineficientă. Apar pe piaŃă multe produse ce nu satisfac concomitent clientul şi<br />
producătorul. Este de apreciat un angajat ce poate vinde capacitatea exactă a firmei. Trebuie să realizăm că în acastă<br />
perioadă de criză nu putem vorbi despre o stopare a vânzărilor, ci despre o încetinire a acestora şi despre nece<strong>si</strong>tatea<br />

Remarcăm tendinŃa generală a organizaŃiilor de a-şi remunera personalul în funcŃie de vânzări. Principala<br />
problemă este deci faptul că nu ştiu să măsoare corect relaŃia de interdependenŃă dintre departamentul de producŃie şi<br />
cel de marketing. În momentul în care este remunerat cel care înregistrează încasări maxime, acesta va fi stimulat să<br />
se axeze către produsele mai scumpe, fără a conştientiza existenŃa marjei profitului sau a capacităŃii de producŃie. Am<br />
demonstrat numeric faptul că, decizia de a vinde cel mai scump produs este o decizie ineficientă. În momentul in<br />
care remunerez angajaŃii, această remunerare poate fi făcută doar prin prisma banilor existenŃi. Dacă vânzările<br />
înregistrate depăşesc milioane de euro, dar costurile aferente producerii acelor bunuri sunt exorbitante, este ineficient<br />
să ofer salarii în funcŃie de vânzări. Vom oferi practic bani care de fapt nu există, bani care au fost acoperiŃi şi<br />
depăşiŃi de investiŃia realizată.<br />

To solve the problem of the relationship of interdependence between production department and marketing<br />
and to find a solution to the problems encountered on the market, as well as in the system of remuneration, we should<br />
be able to answer three questions: What to change? What to change to? How to produce change? (Dr. Eliyahu M.<br />
Goldratt, 1984). The answers are <strong>si</strong>mple: change the behavior of sales department! You change in an efficient rapport<br />
between the two departments! We produce the change in the light of the remuneration system.<br />
Conclu<strong>si</strong>ons:<br />
There are many negative consequences of a wrong approach of the inter-relationships. They were<br />
propagated at the occurrence of the phenomenon of economic cri<strong>si</strong>s. Thus, when the market stops buying, the<br />
organizations remain with large stocks, and loss. In clas<strong>si</strong>cal de<strong>si</strong>gn, production department must do what marketing<br />
asks.<br />
In an ideal <strong>si</strong>tuation, the marketing department should be able to sell the highest company capacity at its<br />
best price. In the context of cri<strong>si</strong>s in particular, the pay should highlight the people who are able to undertake these<br />
tasks. Assume that an employee in the marketing department promotes a product, that product has a low yield of the<br />
narrow place. Regardless the demand, for the organization, the work proves ineffective. There are many products on<br />
the market that do not meet the demands as well with the customer as with the manufacturer. It is appreciated that an<br />
employee can sell the exact capacity of the company. You must realize that in this period of cri<strong>si</strong>s we can not talk<br />
about a completely stop in sales, but about a very slow action. Because of this they need more precise management<br />
of resources and production, in order to not have any longer loss or surplus, as is the time that organizations can not<br />
afford.<br />
It is noted the general trend of organizations to pay their staff according to sales. The main problem is<br />
therefore not knowing to properly measure the relationship of interdependence between production department and<br />
marketing. When we will pay in the light of percentage, the agent will be stimulated to focus more on expen<strong>si</strong>ve<br />
products, and not to realize the profit margin or production capacity. We demonstrated numerically that the deci<strong>si</strong>on<br />
to sell the most expen<strong>si</strong>ve product is inefficient. When we pay the employees, that remuneration must be made only<br />
through the existing money. If sales in excess of million, but costs of producing those goods are exorbitant, it is<br />
inefficient to offer salaries based on sales. We provide practical money actually that can not overlap the investment<br />
made.<br />
What is then the interdependence relationship between the department of marketing and production? A<br />
remuneration system that would promote those who sell full capacity of the organization in terms of efficiency.<br />

The banking system in Romania<br />
Romanian banking system has known in the last decade a spectacular development, given the <strong>si</strong>tuation that<br />
started in 1990, characterized by the existence of an exces<strong>si</strong>ve central banking, most functions being concentrated in<br />
the banking operations of National Bank of Romania, only certain areas being covered by other specialized banks.<br />
The stage of development of Romanian banking system is clearly determined by the overall economic<br />
development in this field. It may be said that the Romanian banking system, although more advanced compared to<br />
other economic branches, is in the tran<strong>si</strong>tional period, being necessary restructuring and development of both<br />
quantitative, in terms of number of banking establishments as well as qualitative improvement, in the sense of<br />
operating structures and modernization activities, implementation of modern products and services that bring<br />
benefits both banks and their clients.<br />
The image of the current Romanian banking system was first contoured mainly by the opening of the<br />
Romanian economy, which resulted in adjustment of the operating requirements and international practices. Banks<br />
have developed and adapted according to the bid requirements of the impact of exogenous factors on the real<br />
economy, as well as the increa<strong>si</strong>ngly pressure from apparent competition in the financial - banking in Romania.<br />
Bank Podium<br />
The trend of banks in the recent years has been to increase the number of units to accelerate bu<strong>si</strong>ness<br />
growth. Banks bets on improving efficiency, increa<strong>si</strong>ng the productivity of each employee, with smaller increases in<br />
assets<br />
Whole banking system assets were in 2008 of 79 billion Euros, up 25% compared to 2007. The year 2008<br />
though brought major changes but in the clas<strong>si</strong>fication of banks by total assets, the most important being the entry<br />
into Top 3 of Volksbank Romania, which jumped 5 po<strong>si</strong>tions in relation to the previous year.<br />
According to data provided by the central bank, Romanian Commercial Bank has the largest number of<br />
actives (21.6% of total assets), each of the 588 actives generating units of over 28 million. With a total value of 16.6<br />
billion Euros, the bank has registered a growth of only 1.8% over the value of assets held in 2007, the holdings being<br />
calculated according to International Financial Reporting Standards (known as IFRS).<br />
The bank located on the second place, by the number of assets, BRD - Groupe Société Générale, had the<br />
fastest growth of assets, 10.7%, reaching a total value of 11.85 billion Euros, representing approximately 15.4 % of<br />
assets held by banks on the Romanian market.<br />
Even Raiffeisen registered a growth of 16% compared to 2007, reaching 4.57 billion Euros (5.9% of total<br />
assets), third place in the clas<strong>si</strong>fication of banks in 2008 is strongly attacked by Volksbank, whose assets have<br />

increased to the value of 4.5 billion Euros. On the fifth place, after Volksbank, is Tran<strong>si</strong>lvania Bank that amounts<br />
5.68% of assets.<br />
Depending on the obtained profit, BCR, ranking leader, has increased net profit after tax by 63.5% to 759.5<br />
million RON. The spectacular growth of Commercial Bank profit has been exceeded by the earnings of smaller<br />
banks, such as Bancpost (with assets of 5.3 billion Euros) and Romanian Bank, both obtaining a triple profit<br />
compared to the one reported during the same period of 2007. Thus, Bancpost reached a profit of 23.5 million<br />
Euros, and Romanian Bank, about 14 million Euros.<br />
A large increase in profit also had the two banks of the rating, namely: BRD - Groupe Société Générale has<br />
achieved a net profit of 515 million lei (140.3 million Euros), compared to 417.20 million lei, registering an increase<br />
of 22.44% and Raiffeisen Bank a net profit of 74 million, 57% higher than in 2007, when profits reached 47.2<br />
million.<br />
To the other extreme, the banks that have seen a decrease in income, the percentages are equally amazing.<br />
The largest decrease in profit was recorded in Libra Bank case, which recorded a net profit of 48 917 lei (13,328<br />
Euros) 8.4 times lower compared to the same period in 2007 when the profit was 412 000 lei. Another sharp decrease<br />
of profits held occurred in Carpatho Commercial Bank (BCC), whose earnings fell by 51.6% to 3.39 million lei,<br />
according to the increase with 17.3% of bank assets by to 2.17 billion as the bank announced.<br />
The list of the banks who have come at a loss in 2008 is completed by the CEC Bank, the player placed on<br />
the ninth place, reported a cumulative net profit of 28 million lei (7.6 million), less than 40% by 2007. Another bank<br />
that reported a contra performance is <strong>IN</strong>G, with a net profit which fell to 1.92 billion, lower by 25%. though keeping<br />
the place in the top 10.<br />
The concept of bank risk<br />
Bank risk is a phenomenon that occurs during the performance of banking operations cau<strong>si</strong>ng negative<br />
effects on those activities by impairing the quality of bu<strong>si</strong>ness, reducing profit or loss recording functionality with<br />
impaired bank. This may be due to internal external bank causes or, generated by the competitive environment. The<br />
concept of risk can also be defined as an undertaking that carries uncertainty because the probability of gain or loss.<br />
In banking, risks assumption can be investigated for its potential future benefits, such as speculative<br />
transactions on the financial markets or exchange, but also the unpredictable pos<strong>si</strong>ble loss. In general, risk taking is<br />
related to the investment that banks have in the economy. Generally, investment risk is the attribute of ownership and<br />
thus its assumption becomes inevitable and justified the existence of banks.<br />
As you know, banks are investing borrowed resources - which are a substantial multiple of their own<br />
capital. Delayed recovery of invested resources causes a number of imbalances in the bank that can put different<br />
forms and can feed each other. The present period is called, “period risk management” in banking system and risk<br />
management is an extremely complex task and management of the bank. Usually, the assumption of risk entails<br />
higher earnings.<br />
Typology of risks<br />
Banking practice has revealed in time a variety of risks. Acuity and their importance varies from period to<br />
period depending on the state economy, transformations that occur in society and the existence and functionality of<br />
the banking system, financial market volatility, etc.., therefore it became necessary to study the systematic banking<br />
risk and their clas<strong>si</strong>fication by different criteria.<br />
In the case of banks the risk is induced by many causes, the biggest being con<strong>si</strong>dered the nature of banking<br />
institution. The bank is faced with certain specific risks, and risk across all operators. Their clas<strong>si</strong>fication leads to the<br />
establishment of the distinction between general and specific risks.<br />
General risk category includes:<br />
- commercial risks (customer risk / product risk, market risk, commercial image);<br />
- risks of goods and persons (risk accident, risk of crime);<br />
- technical and operational risks (the risk of treatment operations on the risk related to<br />
telecommunications);<br />
- internal risk management (regulatory risk, the risk of ethics, strategic risk, operational risk of failure,<br />
the risk management staff, the risk of technological dependence, risk communication).<br />
Risks specific to banks include:<br />
- financial risks (the risk of interest rate risk, liquidity risk on variable-income securities);<br />
- risks of <strong>si</strong>gnature(customer risk, interbank risk, country risk).<br />
220
In its activity, the bank is subject to risks on two plans: on the one hand the bank is liable to face the risks of<br />
their own bu<strong>si</strong>nesses, and on the other hand the bank functions as a specific intermediate in the process of movement<br />
of capital and engages itself in the clas<strong>si</strong>cal banking risks related partnership (counterparty risk).<br />
Bu<strong>si</strong>ness risk arises from the fact that the bank is a bu<strong>si</strong>ness which employs people, capital, and deals with<br />
risks which may result from gains or losses that are paid to employees input factors.<br />
As a company, the bank faces a threefold risk:<br />
- organization of the human connection - that risk brings to the fore the issue of quality management<br />
- material - the risk of downtime or the risk of feather material works in the area and affect the proper<br />
functioning of the banking operation<br />
- ambienal environment - the rules of legal or tax and the negative influences they can exert on the bank<br />
and its profits.<br />
Counterparty risk (partnership): making their profes<strong>si</strong>onal duties, the banks engaged relationships with<br />
depo<strong>si</strong>tors and creditors and particularly with a lot of borrowers, holders of credit or other recipient of services<br />
provided by the bank in this regard is committed different risks in specific partnership ari<strong>si</strong>ng from loans related to<br />
interest or exchange rates de<strong>si</strong>gnated by different names, these words are the same risk - partner.<br />
The main forms of counterparty risk are:<br />
- credit risk - reveals the loss caused by breach of debtors of the options provided in the credit;<br />
- clearance risk - is difficult for banks to procure the necessary resources to meet their commitments at a<br />
time;<br />
- interest rate risk - the risk is diminishing income bank (and so does profits), following the movement<br />
of interest rates.<br />
Another series of risks to which banks are subject to are:<br />
- market risk refers to adverse deviations of market value, the po<strong>si</strong>tion, during the minimum period<br />
required to liquidate po<strong>si</strong>tions;<br />
- the risk of exchange (exchange rate risk) can be defined as the risk of registering losses ari<strong>si</strong>ng from<br />
exchange rate developments. It is closely linked to interest rate risk<br />
- the risk of bank solvency and bankruptcy risk is the risk of not have sufficient funds to cover pos<strong>si</strong>ble<br />
losses;<br />
- operational risks are determined by the quality of bank assets, of the compartments that perform its<br />
functions of the bank;<br />
- technological risk is the type of risk associated with the quality and structure of supply of financial<br />
products;<br />
- new product risk expresses the likelihood of production new combined events: the demand located<br />
below the anticipated level, the overrun cost, lack of profes<strong>si</strong>onal managers, etc.;<br />
- strategic risk - the probability of not choo<strong>si</strong>ng the right strategy in the given data;<br />
- the risk of fraud - the likelihood of committing theft or acts contrary to the interests of the bank by its<br />
employees;<br />
- the risk of human resources - generated by the policy staff through recruitment, training, motivation<br />
and maintenance specialists<br />
- economic risks associated with economic development are the environment in which the bank and its<br />
customers act.<br />
Credit risk<br />
For most of the universal bank credit remains the main active operation. Losses of banks caused by<br />
bankruptcies of debtors are an integral part of the loan. Therefore, the provi<strong>si</strong>ons established by a bank to its<br />
portfolio of loans is a measure of risk assumed by it. Credit risk is in a general formulation, the risk of losses caused<br />
by breach of obligations of debtors provided by the credit. Late payment of interest or rates of events is also a risk.<br />
In its final form the credit risk brings to the bank losses through the debtor bankruptcy, in which case the<br />
losses are irretrievable.<br />
Bankruptcy of a client is in itself a result of development that has degraded over time and whose initial or<br />
subsequent stages, slower or faster, must be received and con<strong>si</strong>dered the best by any normal lender. So the bank, if<br />
necessary, to prevent the credit risk should take preventive measures in time through a rigorous selection of<br />
borrowers. One of the main measures to prevent risks in the banking field, namely, the delegation of deci<strong>si</strong>ons to<br />
grant loans based on risk.<br />
221
The system allows:<br />
- decentralization of deci<strong>si</strong>ons;<br />
- personal liability in certain limits;<br />
- collective respon<strong>si</strong>bility by hiring commis<strong>si</strong>ons, committees and other groups formed as such and<br />
entitled to decide on granting the loan, according to a graduated scale set.<br />
Setting deci<strong>si</strong>ons on bu<strong>si</strong>ness loans is done by analyzing the complex and multilateral projects, through the<br />
prism of economic efficiency and the pos<strong>si</strong>bility of providing the potential for loan repayment conditions.<br />
On the other hand, analy<strong>si</strong>s of the global financial <strong>si</strong>tuation in a <strong>si</strong>gnificant period of time and in all its<br />
details, and feedback based on profes<strong>si</strong>onal motivation, behavior and moral credibility of the management team of<br />
the company are expres<strong>si</strong>ve and binding. This is the case where it should be taken into account, in particular, the<br />
elements about the asymmetry of information and moral hazard, elements which may be deci<strong>si</strong>ve in certain cases.<br />
As regards the distribution of loans granted to the needs of their household, familial, modern technology for<br />
granting focuses on u<strong>si</strong>ng methods information on the methods of credit scoring systems, the special importance of<br />
their selection criteria. They must be small in number but high in <strong>si</strong>gnificance, to provide a differentiation in the<br />
choice of potential customers.<br />
The experience of developed countries underlines the need to develop the portfolio of information on all<br />
bank customers and a base of information proces<strong>si</strong>ng preferably as a main way to strengthen the bank's po<strong>si</strong>tion in its<br />
relations with customers, regardless of their <strong>si</strong>ze, and as a weapon in preventing and avoiding credit risk.<br />
With a great continuity in the selection of clients, updating a database tracking allows the use of credit to<br />
repayment, so you can see in advance any changes in assets and customer bu<strong>si</strong>ness development which would affect<br />
the performance of contractual obligations of the debtor. Referral to appropriate amendments quality claims as<br />
outlined in the management of the bank. It changes optical and working processes towards the client, which is<br />
granted, necessarily, increased as<strong>si</strong>stance to complete a stage which is expected to be tran<strong>si</strong>ent in nature.<br />
Since credit risk is the risk that must be fought, the state, by law and community banking and by precise<br />
rules, creates a bank protection system (in its internal control over banks and external) to be permanently promoted.<br />
Credit risk management<br />
Given the importance that the banking sector stands for any national economy – the vital function that it<br />
performs, namely: the payment system, credit system or the real economy of a vehicle of transmis<strong>si</strong>on of domestic<br />
monetary policy - regulation and prudential supervi<strong>si</strong>on on a main component of the banking system becomes an<br />
essential and at the same time an essential condition for ensuring and maintaining economic and financial health of a<br />
country. The risk is found today in the banking bu<strong>si</strong>ness. Risk management is a key function of modern banks<br />
focused on the market. The operators in international markets are faced with increased volatility and cri<strong>si</strong>s with<br />
repercus<strong>si</strong>ons that can quickly be transmitted from a financial center to another. In this case we talk about systemic<br />
risk and the appearance is made in connection with a <strong>si</strong>gnificant increase in the volume of transactions in financial<br />
derivatives: swaps, futures, options.<br />
Risk management should be understood broader, as an action, and restricted, individually with persons<br />
respon<strong>si</strong>ble for overseeing risk. The risk must be regarded as a conglomerate of risks, often interrelated, in that it<br />
may have common causes that one can trigger production of others. Therefore it is necessary to manage the bank's<br />
overall risk. Objectives of risk management are embedded in the respective bank strategy and specific policies in<br />
various areas of banking and are found in the organizational structures of the banks.<br />
Managing global credit risk has two principles:<br />
- divi<strong>si</strong>on;<br />
- limiting risks.<br />
Credit risk divi<strong>si</strong>on seeks to avoid concentration risk by diver<strong>si</strong>fying investments and loans in particular.<br />
Customer focus in a <strong>si</strong>ngle area of activity is relatively dangerous for a universal bank: during the reces<strong>si</strong>on there<br />
may be operational difficulties. In the sphere of private lending, portfolio diver<strong>si</strong>fication is primarily a territorial<br />
diver<strong>si</strong>fication. Lending economic agents priors the importance of diver<strong>si</strong>fication and economic sector, and on the<br />
foreign customers - geographic diver<strong>si</strong>fication. Banks in Romania propose a diver<strong>si</strong>fication of institutional portfolios<br />
by developing of private sector lending.<br />
On the other hand it may happen that large-<strong>si</strong>zed bu<strong>si</strong>nesses to need to exceed the credit limit reasonable<br />
commitment of a <strong>si</strong>ngle bank. Typically, where the state of the market allows, such firms use markets to provide<br />
financing without intermediates. Another solution is to establish links banking pool. A banking pool is the total<br />
banks of a <strong>si</strong>ngle large enterprise, structured overview of an organized in a precise manner. This solution has the<br />
disadvantage that dilutes the participating banks, but also the benefits of dividing of risks. The pool allows small<br />
222
anks to finance large enterprises (operation less risky and less expen<strong>si</strong>ve) and has greater authority to impose a<br />
recovery plan for the debtor in case of difficulty.<br />
Limiting risk is of a normative and prescriptive. Each bank, depending on the quality of economic<br />
environmental and development of its own parameters, ensures the limitation of risks in two ways: global and<br />
analytic, as follows:<br />
- setting a limit of its own, internal, its global commitment in risky but profitable, operations. It being<br />
set a maximum limit for the risky share (investment) in total assets or relative to capital bank account;<br />
- setting credits ceilings on debtor, group of borrowers, activity sectors or geographic areas to prevent<br />
<strong>si</strong>gnificant changes in the economic <strong>si</strong>tuation of these groups to negatively affect their exposure.<br />
Very useful may be also the internal limits set on the ba<strong>si</strong>s of cri<strong>si</strong>s scenarios, limits hard to define when the<br />
cri<strong>si</strong>s occurs, it is preferable that the bank be prepared for the event of a cri<strong>si</strong>s, as it would seem unlikely in a given<br />
context.<br />
Depending on financial performance and debt service, loans are clas<strong>si</strong>fied into five categories (Table 1).<br />
Financial performance evaluation is done by each company and bank loans will be included in one of the<br />
following categories:<br />
- category A: very good performance, allowing payment at maturity of the debt, while maintaining the<br />
performance;<br />
- category B: good performance, but uncertainly of a medium prospect;<br />
- category C: satisfactory financial performance with the tendency of worsening;<br />
- category D: low financial performance and cyclical;<br />
- category E: losses and the inability of repayment.<br />
Debt service can be appreciated as:<br />
- good: refunds with maximum delay of 7 days;<br />
- weak: delays of up to 30 days;<br />
- inadequately: late over 30 days.<br />

Basel I and Basel II impact in Romanian banks<br />
Global legislation which establishes a global link between equity of financial institutions and the risks they<br />
assume it is known as the Basel Agreement. Basel Committee on Banking Supervi<strong>si</strong>on introduced in 1988 the<br />
Agreement concerning the Capital to cover risk. Banking bu<strong>si</strong>ness, practice risk management, the approaches of the<br />
supervi<strong>si</strong>on and the financial markets have had <strong>si</strong>gnificant changes <strong>si</strong>nce that year. Merits of the Agreement of 1988<br />
were recognized in more than 100 countries, including the countries of central and eastern Europe introducing it in<br />
the national banking systems.<br />
Knowing what the importance to establish a solid legal and transparent framework can have on rendering<br />
self confidence in the banking system, the international authorities submitted in June 1999 new proposals to improve<br />
the Basel I rules, whereas in the latter there were some limitations on that asses<strong>si</strong>ng capital requirements based on<br />
rigid methods of calculating the exposure to credit risk. Thus, the degree of credit risk granted for economic agents,<br />
secured by mortgages, pledges, transfer debt etc. was 100%, regardless of their standing economic and financial, of<br />
the strategic importance for the national economy, the credit rating for debt service, etc. On the other hand after<br />
completion of Basel I, it was registered a development of methods and techniques of risk assessment used in parallel<br />
by leading banks, who have created their own systems of risk assessment based on probabilistic methods, which<br />
estimated losses potential for credit risk, market and operational.<br />
Since the end of 2006 banks in the European Union have been aligned to the new Basel agreement (Basel<br />
II), the agreement being applied to Romania when it joined the European Union. The need of Basel II occurred as a<br />
result of improving the quality and complexity of asses<strong>si</strong>ng exposure to risk, including the introduction of<br />
operational risk equation.<br />
223
Thus, according to Basel II, risk exposures can be assessed both through standardized methods <strong>si</strong>milar to<br />
those currently existing under the Basel I, as well as through methods based on historical observations and methods<br />
of mathematical probabilities. In this respect, it should be borne in mind that for more advanced methods, banks must<br />
have historical databases (with information from several years) that underpin the forecasts indicator.<br />
Subject to several conditions and minimum requirements on information disclosure, banks that have<br />
received approval to use the approach based on internal assessment of credit risk (IRB) may rely on their own<br />
internal estimates of risk components. Components of risk include: where the probability requirement (probability of<br />
default - PD), loss caused by failure obligation (loss given default - LGD), exposure to risk of default (exposure at<br />
default - EAD) and maturity (M). IRB approach is based on the measurement of unexpected losses (UL) and<br />
expected losses (EL).<br />
The new provi<strong>si</strong>on pays close attention to determining the need for adequate level of capitalization of<br />
financial institutions as a function of aggregate level of risks to which they are exposed in the conduct of their<br />
activities. However, these regulations sought, in equal measure, the fundamentals of a convergence in prudential<br />
supervi<strong>si</strong>on, to ensure a transparent and competitive environment for all banks operating in the world. The ultimate<br />
goal was ultimately represented by the improvement of bank policy risk management and adaptation to the financial<br />
realities of a world characterized by a high degree of uncertainty and volatility of the particular capital flows.<br />

1. Introduction<br />
A few years ago, the companies were wondering about the role of the internet regarding the performance of<br />
their bu<strong>si</strong>ness, and today, they do not do without it. Even though initially, bu<strong>si</strong>ness people have con<strong>si</strong>dered the<br />
internet to be just an opportunity for saving money, now the internet targets the communication management process<br />
with regard to improving the efficiency of the transactions, adding value and increa<strong>si</strong>ng clients’ implication (Berton<br />
et al, 2003).<br />
The internet should be con<strong>si</strong>dered in the context of commercial and social progress. It should be used not<br />
only for selling, but also for creating the marketing mix. In this way, it should be more than just a place where the<br />
image and the company’s products are presented; it should change the occa<strong>si</strong>onal vi<strong>si</strong>tors into potential clients, and<br />
moreover, to persuade them to become active clients (Constantinides, 2002). So, the online marketing tools are not<br />
used just for adverti<strong>si</strong>ng to a pas<strong>si</strong>ve public, but they refer also to building and participating in commercial and social<br />
communities.<br />
In the traditional marketing communication model, there is just a communication way, taking into<br />
con<strong>si</strong>deration homogeneous consumers, without the interaction opportunity. In the new marketing communication,<br />
the companies can interact with the clients and can deliver them content. For this reason it is necessary to rede<strong>si</strong>gn<br />
the marketing concept and its functionalities for including the consumer in the marketing process and it is also<br />
needed the rede<strong>si</strong>gn of activities in order to become adapted to the internet. Therefore, it is very important for the<br />
companies to know the environment where their consumers interact, so that they can become active agents in the<br />
interactive process and an integrant element of the company’s commercial strategy (Hoffman, Novak, 1996). Faigin<br />
(1997) assumes that a coordinated and coherent strategy will bring the consumers on the internet.<br />

2. Literature review<br />
226
The opportunities offered by the internet as a marketing instrument have been deeply analyzed (Cronin<br />
1996; Chaffey, 2004) but there are still few researches about the efficiency and their impact. The results of these<br />
instruments should not be measured only at the audience’s dimen<strong>si</strong>ons, as many authors did (Lichtenthal, Eliaz,<br />
2003; Ellsworth, 1995; Glossbrenner et al., 1995), but they should take into con<strong>si</strong>deration the specific objectives of<br />
the bu<strong>si</strong>ness, which can vary from company to company. The web<strong>si</strong>tes contribute to achieving the objectives, in this<br />
case, there should be evaluated their efficiency. If a web<strong>si</strong>te has a high commercial potential, this potential can be<br />
difficulty attained except the case when the objectives are clearly stated and integrated in the company’s strategy<br />
(Porter, 2001; Strauss, Frost, 2001). Lichtenthal and Eliaz (2003) con<strong>si</strong>der that the internet is the only way to achieve<br />
all the communication objectives. Moreover, its performance can be correlated with the investments in this field.<br />
The appearance of the internet, as an environment and as a support platform for commerce, has brought<br />
major changes also in the way companies compete. The organizations that do not take advantage of this technology<br />
and the instruments that appeared together with it are seen as not offering added value to the services delivered to<br />
their clients, so they incur a competitive disadvantage. Obviously, the internet offers the companies different<br />
instruments that they can use in order to adapt to the clients’ diverse needs and which could be used in order to<br />
obtain competitive advantage from the economic and / or strategic point of view. In return, companies that use the<br />
technology (having at least a corporate web<strong>si</strong>te where the products are presented), are seen as being in a continuous<br />
fight to satisfy the current needs of their clients. These companies incur low costs and so they can focus their efforts<br />
to delivering high quality products. This general tendency has created pressures on those bu<strong>si</strong>nesses that use only the<br />
traditional means and instruments. Consequently, the use of online marketing tools is imperious in managing<br />
customer relationships, because it helps the companies to better understand their clients, to deliver personalized<br />
services and to retain them.<br />
For understanding the role played by the use of digital instruments in managing customer relationships,<br />
other researchers have treated this problem by examining the way the internet is used by the companies in their<br />
relations with the clients and online communities (Adam et al., 2002). Boyle (2001) has reported that the usage of<br />
internet, as a substitute of the traditional instruments employed by the companies in their relationship with the<br />
customers, has increased. In addition, Bradshaw and Brash (2001) have highlighted the fact that organizations<br />
become more efficient in managing relations if u<strong>si</strong>ng the internet. The enterprises need to improve their capacity of<br />
serving their best clients and transform them into loyal customers as well as identifying and attracting potential<br />
clients, for sustaining a profitable increase. Even though, there is a continuous need to examine, empirically, the<br />
impact of u<strong>si</strong>ng the internet in the different dimen<strong>si</strong>ons of the customer relationship management – the understanding<br />
of customer’s behavior, offering personalized services and gaining its loyalty.<br />
Previous research have examined the usage of digital instruments in managing customer relations, both in<br />
SMEs and large companies (Dutta, Segev, 1999; Hamill, Gregory, 1998; McGowan et al., 2001), in the field of<br />
services and B2B (Berthon et al., 1999), in different geographic regions (Adam et al, 2002; Dutta and Segev 1999).<br />
Although the web has become an integrant in all marketing activities done by the companies, it is obvious<br />
that the offline strategies de<strong>si</strong>gned by companies are not always reflected in the online world, being that this<br />
environment has unique characteristics who ask for special theoretical and practical con<strong>si</strong>derations. The way in<br />
which the organizations present themselves on the internet and manage their activities u<strong>si</strong>ng online marketing tools,<br />
vary depending on the strategy and the global objectives of the company.<br />
As a consequence of the fact that the number of web<strong>si</strong>te vi<strong>si</strong>tors have rapidly increased, the competition<br />
among the organizations has inten<strong>si</strong>fied. The companies are confronted with difficulties in differentiating themselves<br />
from competition and gaining new clients. Therefore, companies rethink and rede<strong>si</strong>gn new methods and means to<br />
increase sales and profits. Relationship marketing and the accent on customer relationship management is not a new<br />
phenomenon. This perspective has been discussed in the marketing literature in the past decades. The concept of<br />
relationship marketing was introduced in the services marketing by Leonard Berry in 1983. On the services market<br />
and B2B, where there is a limited number of clients and / or where the interactions with the clients constantly appear,<br />
it is ea<strong>si</strong>er to preserve relationships. When a company is presented on more markets, the relation is more difficult to<br />
be obtained, but it can be profitable and is definitely pos<strong>si</strong>ble with the use of digital tools.<br />
So the relationships with the clients become determined by the success of the bu<strong>si</strong>ness <strong>si</strong>nce loyal clients<br />
tend to become less sen<strong>si</strong>tive to price changes and more attentive to the relationship developed with the companies.<br />
Reichheld (1996) highlighted that profits can grow as a result of customer retention. That is why, companies that do<br />
not focus on managing customer relations, risk to lose a huge number of clients from the internet, in the favor of their<br />
competitors.<br />
The online marketing tools, for instance the email, web<strong>si</strong>te, social networks, blogs etc., and generally the<br />
internet, are effective, efficient and interactive means to obtain useful information about the potential clients. For<br />
organizations, no matter the methods used for collecting information, they represent knowledge about the customers’<br />
227
ehavior. As a consequence, companies can offer personalized products to respond to the individual needs of their<br />
clients.<br />
Galbreath (2002) illustrates the fact that processed information is used to create a better user experience, for<br />
instance personalization, which can lead to increased trust and loyalty towards company and its products.<br />
It is very important to understand the needs and wants of each person, as well as to know and respect his<br />
preferences. Dolan (2001) noted that clients’ preferences represent the heart of marketing. Generally, when analyzing<br />
customer’s behavior, the most important aspect studied is the way the consumers make buying deci<strong>si</strong>ons (eg. the<br />
process by which the get to choose that specific product / service, not another one).<br />
Such, companies need to explore any source they have at hand for obtaining information about clients,<br />
which will give them the opportunity to maximize sales and profit. Apparently, the internet is an efficient place to<br />
collect information (Boyle 2001; Hoffman, Novak 1996). With the instruments used, the internet becomes a meeting<br />
place between companies and clients, in the virtual space, and which collects information about them. Arnott et al.<br />
(2002) suggests that the interactivity offered by online instruments increases the capacity of the companies to<br />
understand customers’ behavior and helps them to offer them the services they want and need. Therefore, u<strong>si</strong>ng<br />
online marketing tools has a po<strong>si</strong>tive impact in understanding customers’ behavior.<br />
There should be taken into con<strong>si</strong>deration that digital instruments offer the opportunity to personalize both<br />
the messages sent to potential clients, but also the products and / or services delivered. Gummesson (1996) noted the<br />
importance of u<strong>si</strong>ng online marketing tools in building and managing bu<strong>si</strong>ness relations. An efficient usage of these<br />
relationship marketing tools assumes a step forward from attracting new clients to developing, and preserving<br />
present relations – increa<strong>si</strong>ng consumers’ loyalty.<br />
3. Online marketing tools used in customer relationship management<br />
Online marketing is done by those individuals or organizations which exchange ideas and offers by u<strong>si</strong>ng<br />
computers, online networks and interactive media, in order to reach their marketing objectives. (Vegheş, Pantea,<br />
2008).<br />
The most important online marketing tools that can be used by companies for attracting, maintaining and<br />
developing profitable long term relationships with their clients are: web<strong>si</strong>tes (where there are included also those<br />
tools used for attracting the customers to the company’s web<strong>si</strong>te: online ads, sponsored links, advergaming etc.),<br />
email marketing campaigns, newsletters, blogs, RSS feed, forums, online discus<strong>si</strong>on groups and instant messaging.<br />
Next, there are presented each of the tools mentioned above and the way they can be used for achieving the<br />
marketing purpose settled – relating with clients.<br />
is<br />
3.1 Web<strong>si</strong>te<br />
A in its essence a marketing tool which only costs its owner once, and it stays in people’s<br />
attention for an unlimited period of time. Its objective is to support the promotional activities, being <strong>si</strong>milar to a<br />
billboard where potential vi<strong>si</strong>tors can find details about the company, its products/services, contact details etc. This<br />
type of information dissemination saves time for the company, but also for the clients, offering a complete and free<br />
instant access to the company and its products.<br />
Nowadays, most consumers have come to con<strong>si</strong>der a successful company, a company that owns a web<strong>si</strong>te.<br />
The lack of a web<strong>si</strong>te can make the youngsters categorize the company as an unprofes<strong>si</strong>onal and inexperienced one.<br />
If the web<strong>si</strong>te is de<strong>si</strong>gned so that it reflects the image the company owner wants, it will attract new clients and it will<br />
help maintaining the old ones. In addition, if a customer heard about a company and wants to learn more about it and<br />
does not find a web<strong>si</strong>te, it is very probable to get to a competitor’s web<strong>si</strong>te.<br />
A web<strong>si</strong>te offers the pos<strong>si</strong>bility of making bu<strong>si</strong>ness 24 hours a day, 7 days a week because the information<br />
is available and permanently acces<strong>si</strong>ble. Through the web<strong>si</strong>te, companies can keep in touch with its clients, inform<br />
them about new promotions, new products / services, special events that the company involves in.<br />
Online marketing campaigns offer not only the opportunity of precisely selecting the communication target,<br />
but it does also save time and money. Their objective is to increase traffic to the web<strong>si</strong>te, which leads to increase in<br />
sales and company’s profits.<br />
Next, there will be presented the most appreciated online marketing tools used in order to attract potential<br />
clients to company’s web<strong>si</strong>te:<br />
¡¤��£�¤<br />
��������©£¨�©¢£¤�£��<br />
The email represents the result of the natural evolution of the mailing. Email marketing is used in order to<br />
inform potential consumers and current clients by the use of the internet. The email or the electronic mail is one of<br />
228
the most efficient tools from the direct marketing’s arsenal on the internet, from the investment’s profitability point<br />
of view. The results regarded by an email marketing campaign is achieving sales from 5 to 15% of the cases, as<br />
compared with 0,5 to 2% in the case of the banners.<br />
There are two forms of email communications: ��¤����§�¤¢: due to the presence on the companies’ web<strong>si</strong>tes of a<br />
contact page, the organizations offer their potential and / or current clients the opportunity to get in touch with them.<br />
The client sends an email where he explains the problems or complaints that he has concerning the product he has<br />
bought, or asks for details regarding a certain product. The company will answer also by email in the shortest time.<br />
The email is the cheapest web solution of the customer relationship management strategy (eCRM). Its main<br />
disadvantage is that it does not offer the opportunity to communicate with the client in real time.<br />
An important aspect is related to the companies’ capacity to manage their clients’ replies to emails. It is<br />
imposed that when receiving the message, an email of confirmation to be sent immediately, and the clients’<br />
requirements to be redirected to the respon<strong>si</strong>ble departments in the organization.<br />
:<br />
��©£¨����§�£�©�£��£�£�£©�¤��<br />
the email is a valuable tool for sending short messages that<br />
call for action on behalf of the recipient. The companies usually develop email marketing campaign with the purpose<br />
of maintaining current customers, build buyer’s loyalty, improve the relationship between the client and the seller,<br />
announce or remind the clients about different offers or special events they can attend. In order for such a campaign<br />
to be efficient, the messages should be addressed to a target, so that the rate of response is high. Usually there are<br />
inserted links to a “landing page” (a web page where it is driven the person who click on the link inserted in the<br />
email, which offers additional information concerning the products presented in the message). The email is the most<br />
spread internet application, which can be used strategically in direct marketing reasoning and in the bilateral<br />
communication with the target.<br />
The main advantages of email communication are:<br />
- the informational content and the relationship sender - recipient – the beneficiary can receive complex<br />
information (images, audio, video files or documents) rapidly and conveniently. He can read them whenever he<br />
wants, without incurring problems such as when u<strong>si</strong>ng phone communication, where even though there is fast<br />
communication, there can be the case when the interlocutor can not talk at the moment of calling or does not<br />
understand well the message due to the circumstances he finds himself in. It can also be attached a short presentation<br />
movie where the product is presented and its features or there can be added representative pictures about the object<br />
of the direct email campaign;<br />
- in most cases, the feedback is more con<strong>si</strong>stent than phone calls or mailing, because the interlocutor can<br />
reply whenever he wants, however he wants and whatever he wants;<br />
- probably the costs are the most important advantages to be taken into con<strong>si</strong>deration, both by the<br />
organization and the beneficiary of the communication. They are lower then any other existing communication mean.<br />
That is why the beneficiary of the communication will have the reasoning to answer, <strong>si</strong>nce in most of the cases, he<br />
does not incur any additional costs;<br />
- segmentation and targeting – both strategic components receive a special <strong>si</strong>gnificance when u<strong>si</strong>ng the<br />
email. Thus, the campaigns can be ea<strong>si</strong>ly customized according to the consumers’ particularities;<br />
- the results of an email marketing campaign can be ea<strong>si</strong>ly measured with by u<strong>si</strong>ng special software, which<br />
��©£¨����§�£�©�£��£�£�£©�¤�� ��¤����©�<br />
generate reports based on the number of emails opened by the recipients. When the company inserts links to the<br />
landing page, the soft reports how many times those links were accessed. The main advantages of including links in<br />
the sent message are, on one hand the increase of traffic on the web<strong>si</strong>te, as well as the registered persons.<br />
The electronic message should be developed starting from the current po<strong>si</strong>tioning of the organization<br />
(including its products / services / brands) and to materialize intro an attractive offer for potential consumers<br />
(Vegheş, 2003).<br />
The email is a valuable marketing tool for conveying short, <strong>si</strong>mple messages that call for action on behalf of<br />
the recipient. Usually companies develop email marketing campaigns for attracting new customers, persuading the<br />
existing customers to buy again, encourage customer loyalty, announce or remind about special offers or events etc.<br />
For an email marketing campaign to be efficient, it is wanted a greater number of responses from those in the target.<br />
��������¨£�¤©��¤¢�£�£��<br />
An online ad is somewhat <strong>si</strong>milar to a traditional advertisement we would see in a printed publication such<br />
as a newspaper or magazine, but it has the added ability to bring a potential customer directly to the advertiser's<br />
web<strong>si</strong>te (Boyle, 2001). An online ad also differs from a print ad in its dynamic capability. It stays in one place on a<br />
page, like a magazine ad, but it can present multiple images, include animation and change appearance in a number<br />
of other ways; moreover, depending on the target, companies can choose which online ads to be seen by those<br />
229
targeted (eg. only persons from Bihor county).<br />
The technology used for delivering the online ads is called AdServer. According to its performances there<br />
can be obtained precious information regarding the number of page views, the click rate or there can be de<strong>si</strong>gned<br />
campaigns based on geographical criteria or the frequency page views / user.<br />
The online ads can be clas<strong>si</strong>fied according to: ���¤�¤�£��– there are static, dynamic (animated) and interactive ads; ���¤�£�¤��£���IAB (Interactive Adverti<strong>si</strong>ng Bureau) the authority in this field of activity, has defined<br />
some standard formats called (http://www.iab.net/standards/adunits.asp) and the main<br />
categories are: banners and buttons; skyscrapers; rectangles and pop-ups: ��©��¤¢©��: these are rectangular advertisements which generally appear horizontally at the top of<br />
the web page. Some are static while others use graphics, video and audio to capture the vi<strong>si</strong>tors’ attention. While this<br />
style of ad is popular, many web users are so familiar with them that they are beginning to ignore them. As a result,<br />
advertisers have started creating variations on the banner ads, in which some will automatically fill your web page<br />
when you first open it and then shrink back to normal <strong>si</strong>ze. These types are banner ads are proving more successful<br />
with higher click-through rates than those that remain one <strong>si</strong>ze. Still, banner ads account for more 54% of online<br />
adverti<strong>si</strong>ng revenues; ��§����©�: A graphical adverti<strong>si</strong>ng unit, smaller than a banner ad and square or rectangular in<br />
shape. Whereas banners are often placed at the top or bottom of a page, buttons are often placed towards the middle<br />
of a page on the left<br />
£��¤¢©��£�¤�©¢£¤�£��§�£��<br />
or right <strong>si</strong>des; ��¢©�¤¢©���: these are <strong>si</strong>milar to banner ads except that they are po<strong>si</strong>tioned<br />
vertically down the <strong>si</strong>de of the web page which allows them to be bigger - often be 2 - 3 times larger than a banner<br />
ad. Sidebar ads are con<strong>si</strong>dered more effective than banner ads because they are bigger, and the ad does not disappear<br />
so quickly when the user scrolls down the web page. As a result, more people will click on a <strong>si</strong>debar ad which means<br />
advertisers will pay more for <strong>si</strong>debar ads than banner ads; �����§�©��: these advertisements appear in their own, small browser window. Many web users<br />
con<strong>si</strong>der these types of adverti<strong>si</strong>ng extremely irritating because the ad obscures the web page they are trying to read,<br />
forcing them to either close or move the window out of the way. However, more users click on pop-up ads than<br />
banner ads, but many access them by mistake or with the de<strong>si</strong>re of clo<strong>si</strong>ng it as soon as pos<strong>si</strong>ble. ��£�¤�©¢©����£<br />

Online ads are recommended to be used mostly in the campaigns de<strong>si</strong>gned to increase awareness due<br />
to the low rates of response (about 1% clicks) the success being influenced by factors such as: the creative message<br />
used; the period and the duration of the campaign; the formats of the online ads used; the location of the ads in the<br />
web<strong>si</strong>tes; the rate of loading of the web<strong>si</strong>te with other campaigns.<br />
The main reasons for not u<strong>si</strong>ng online ads are: the phenomenon of (the spaces from a<br />
web<strong>si</strong>te where the banners are placed become invi<strong>si</strong>ble, so the user ignores them), the pos<strong>si</strong>bility of being blocked by<br />
AdBlocker (software that blocks the appearance in the browser of the flash format in which the ads are de<strong>si</strong>gned). £��£�£�¨¤�©��¤¢� ©���§�£�©��©���¢ ©����£�£ ¤��¤��£�¨¤©����¨�©�£��©����©�¤�¤¤¨©����¤¢¨©<br />

Daily, there are millions of people who use search engines in order to find information. The majority of<br />
them do not go further than the first page of results, and most of them do not go further than the third page of results<br />
retrieved by the search engine.<br />
Search engine optimization is the process of improving the volume and the quality of traffic towards a<br />
webpage, from search engines. It has a more technical nature, combining programming elements with persua<strong>si</strong>on,<br />
selling and pas<strong>si</strong>on to solve puzzles in a written form capable to maintain the wanted level of turnover and in the<br />
same time being in the top of the retrieved results. It is not just a technical process, nor does it belong to the<br />
copyright or links or registration in the search engines, but it is a complex combination of more than one hundred<br />
variables in a web<strong>si</strong>te’s compo<strong>si</strong>tion. Its obtaining is rather difficult without the methodology and the required tools.<br />
In order to succeed in u<strong>si</strong>ng search engines as online marketing tools, the point of interest should not be<br />
placed on how these search engines work, but rather on the mentality of the one who is searching – the potential<br />
buyer. Marketers and web<strong>si</strong>te administrators should find key words, then to correlate them with the content of the<br />
pages, then to make sure that the page where the vi<strong>si</strong>tors are redirected is appropriate, and of course, to make sure<br />
that the vi<strong>si</strong>tors are buying a product or do the de<strong>si</strong>red action. It is nice to see that the web<strong>si</strong>te has increased traffic, it<br />
is more wanted to attract clients, but of course it is ideal to succeed in combining those two (what keyword phrases<br />
result in terms of most traffic).<br />
Some optimization processed of search engines implies the optimization of the source of the web<strong>si</strong>te, the<br />
presentation and structure, without making notable changes for the users, for instance the implementation of a<br />
230
hierarchical structure of the web<strong>si</strong>te, including a unique content that can be ea<strong>si</strong>ly indexed and extracted by search<br />
engines when retrieved by users.<br />
Search engine optimization is a last generation weapon that the marketers can use, which incurs low costs<br />
and high results.<br />
Marketers bet on key words expected to be more frequently used by the target when searching for those<br />
products and services that they want. For instance, if the product wanted to be sold is represented by red roses, of<br />
course the key words used should be “red roses”, and hoping that the potential client would type these words; he will<br />
see the company’s link and will get to its web<strong>si</strong>te. �����������¢¤�¨£�£�<br />
This type of adverti<strong>si</strong>ng is called sponsored link or contextual adverti<strong>si</strong>ng and it usually appears in the right<br />
or sometimes above the results retrieved by the search engines. The organization only pays when the user accesses<br />
the sponsored link.<br />
Many of the companies present on the internet are u<strong>si</strong>ng games for attracting clients, expo<strong>si</strong>ng them<br />
messages about the company’s brand and in the same time collecting data about these potential clients, registering<br />
them in a database. This strategy that involves the combination of adverti<strong>si</strong>ng and marketing elements, in an online<br />
game, is known as advergaming.<br />
Companies are spending from thousands of euro (for a two-dimen<strong>si</strong>onal Java-base game) to hundreds of<br />
thousands of euro (for a 3-D game), because it is con<strong>si</strong>dered that these games will bring gains in what po<strong>si</strong>tioning is<br />
concerned. ���������¤¢�©�£��<br />
All online marketing tools presented above have as main objective to direct the vi<strong>si</strong>tor to the company’s<br />
web<strong>si</strong>te and to determine him to become the client of that company. Next, there are presented those online<br />
instruments that companies can use in order to maintain and develop long term relationships with their clients:<br />
3.2 E-newsletter<br />
The newsletter is a periodical message sent online to the company’s database of subscribers who have<br />
previously agreed to receive it. It usually contains one or more of the following tools: an article / interview /<br />
editorial, case study, news, special offers / promotions, new projects / up-coming events, contests, polls or other<br />
resources.<br />
The difference between the email marketing and newsletter is that the email marketing calls for immediate<br />
action from the recipient while the newsletters are meant to develop a long-term relationship between the sender and<br />
recipient. Newsletters are intended to offer the readers added value; they are more personal and informative.<br />
When planning the online marketing strategy, these instruments should not be treated separately. For<br />
instance, the newsletters sent by email can be promoted on the web<strong>si</strong>te and vice-versa. Combining different<br />
instruments offered by the internet in a <strong>si</strong>ngle strategy can improve the rate of its success.<br />
Before setting up a newsletter campaign intended to attract or increase loyalty of customers there should be<br />
clarified the following aspects: (potential and company’s existing clients);<br />
(relevant content, information on how the products or services can be used, the field of activity);<br />
(it should be correlated with the information sent and the<br />
recipients’ expectations); (eg. the page<br />
where they can find out the results of the case study presented in the message); ��¤��¡¤��£�¤�����¤�©��©£��(brand (the emails can be in text format – smaller dimen<strong>si</strong>ons – or HTML, which offer a plus in de<strong>si</strong>gn and<br />
paging); by potential clients, increase customer loyalty or sales;<br />
secondary objectives such as increase the number of subscribers, the rate of opening the message, click-rate on the ��¤�©��©£�� ��¤�¤����¨�� ��¤¨©��£���©�¤¡�¤¢¤��¤����§�¤¢����¤�£¢¤��¤����£����¢¤£���¢�©�£�� ���¤��£����¤�¤¡�¨¤��¤¢ �¤�¤¢�£�¤��¤�¢¤¢§¤�� �¤¡�¨¤��¤¢ ��¤���£�����¤ �¤�£�£����¤�©¢�¤�<br />
links).<br />
recognition<br />
The technological solution used in de<strong>si</strong>gning the newsletters should allow personalized communication, as<br />
well as a database that registers other information be<strong>si</strong>des the email address of the person.<br />
3.3 Online community<br />
People tend to believe that each company has only one goal, the gain and this is what they see behind any<br />
promotional or informational message. This is the reason why companies should continuously search for new<br />
resources of gaining the trust and legitimacy of the consumers.<br />
§�¤���¢£��¨¤�¤��£��<br />
231
Customers buy from people they know and they trust. Clients trust the brand firstly because they trust the<br />
managers of the company, its specialists and / or its employees. That is why the companies should treat very<br />
carefully the public image of its employees. An online community has as main objective to get into contact persons<br />
with common concerns.<br />
A blog (web log) is a user-generated web<strong>si</strong>te where entries are displayed in a reverse chronological order.<br />
Even though sometimes the term is explained as “online journal”, the blog does not necessarily imply a low quality<br />
of content and not even an informal or semi-formal tone. In return, when it is used for personal branding of the<br />
management of the company or of its employees, it is a very good instrument to highlight their personality.<br />
People can communicate on the blog personal experiences, opinions about important events, links or images<br />
with things that kept their attention. In addition, the blog permits the owner to receive feedback from the readers; to<br />
be quoted on other blogs etc. In the last years, more and more managers and experts have de<strong>si</strong>gned blogs and more<br />
and more companies use this method to communicate with theirs stakeholders.<br />
Micro-blogging is a Web 2.0 tool, which allows sending short messages or links to those interested, and the<br />
best example is Twitter.com, which is <strong>si</strong>milar to a chat room, where companies can send short messages to potential<br />
clients, or can connect with them, by u<strong>si</strong>ng this service. This instrument allows companies to see what the public<br />
states about the organization and to offer additional information to the clients, to solve different problems or clarify<br />
problems.<br />
RSS feeds (Really Simple Syndication), also called web feeds, are a mean for sending content, which, if<br />
handled adequately it can create online traffic due to the high rate of refresh of information. News web<strong>si</strong>tes, online<br />
personal blogs and companies can include RSS content such as: news about the company or product, vacancies,<br />
information regarding new posts on the <strong>si</strong>te, etc.<br />
�������¨��¡����¤¤�<br />
Social networks are dynamic systems which nurture relationships between people through the content they<br />
create and share. Their rate of usage has increased, not only in Romania, but also world-wide. As a consequence, this<br />
is involuntarily forcing advertisers and marketers to rapidly evolve customer relationship through social networks.<br />
Both blogs and social networks have developed due to the individual needs to tell their story and share their<br />
feelings and opinions. These web<strong>si</strong>tes offer the opportunity to become acquaintances and preserve friendships in the<br />
virtual environment. There has come to more than 150 web<strong>si</strong>tes of this kind, most important being: facebook.com,<br />
myspace.com, flixter.com, LinkedIn, hi5.com, tagged.com, etc. but also classmates.com, myyearbook.com,<br />
blackplanet, a<strong>si</strong>antown.com etc., each having its specific audience.<br />
Brian Solis points out the fact that social networks such as facebook, myspace, twitter, yelp and other online<br />
communities should transform online marketing into an opportunity to engage and interact with customers. Social<br />
networks have become an obses<strong>si</strong>on for branding, adverti<strong>si</strong>ng, marketing, and communications between experts and<br />
profes<strong>si</strong>onals worldwide. Many bu<strong>si</strong>nesses are building social channels to broadcast messages in a one to many, topdown<br />
practice that not only prevents relationship building, but impedes any hope of cultivating communities and<br />
empowering customer relationship (Solis, 2009).<br />
Moreover, John Burbank, the CEO of the Nielsen Company is convinced that social networking has become<br />
a fundamental part of the world and "will continue to alter not just the global online landscape, but the consumer<br />
experience at large." (Burbank, 2009). The organization he represents estimates that on a global ba<strong>si</strong>s, at every 11<br />
minutes, one minute can be attributed to social networks, blogging web<strong>si</strong>tes, or other types of online community<br />
activities.<br />
Marketers from organizations should learn how to use this instrument, firstly in order to create a corporate<br />
profile and then to interact with the other members of the network, to establish relationships.<br />
���������£©¨�¤�¡�¢£�<br />
��������¢§��¡��¨£�¤�£��§��£���¢�§��<br />
One of the best ways to generate traffic online towards the company’s web<strong>si</strong>te or personal blog is to<br />
participate in the discus<strong>si</strong>ons within online communities. These communities can be discus<strong>si</strong>on groups, some of them<br />
by email (eg. Yahoo groups) or forums, made available by the company on its web<strong>si</strong>te. Most of the discus<strong>si</strong>ons and<br />
debates are related to topics such as important problems of different industries, which call for the participant’s<br />
reaction. This is the reason why online discus<strong>si</strong>ons are excellent opportunities to help and offer added value to a<br />
target (potential clients, partners, journalists, etc.). Because the members of these groups are always interested to<br />
know their interlocutors and it is de<strong>si</strong>red to know the person who comments on forums. This is the reason for<br />
including in the messages posted a link to own web<strong>si</strong>te or blog.<br />
232
A discus<strong>si</strong>on group or a forum allows the participants to debate on subjects they are directly interested in. It<br />
is assumed there are more than 10 million people actively involved in online discus<strong>si</strong>ons and that there are more than<br />
15.000 different topics they talk about. The purpose for u<strong>si</strong>ng these tools is to attract new customers, communicate<br />
with existing ones, market research, improve brand awareness.<br />
For attracting potential clients to a forum or a discus<strong>si</strong>on group it is necessary firstly to identify a group that<br />
corresponds to that product’s or service’s target. The messages sent should be supervised in order to familiarize with<br />
the different topics and to the rules imposed. In the next stage, there are sent messages by the company, short ones<br />
and they should begin with a description of a way it can help the members of the group. It is important to monitor<br />
these forum and online groups in order to prevent the dissemination of false information about the company.<br />
3.4. Instant messaging<br />
The usage of the interactive dialog window (chat) as a direct communication instrument has as a purpose<br />
getting in touch with customers, for answering questions related to the products bought, instructions for u<strong>si</strong>ng the<br />
products, but also for answering potential customers to different concerns regarding the products or services offered.<br />
The great advantage offered by this tool is the facility of real-time communication to a representative of the<br />
company.<br />
This is an application that eases direct communication between clients and customers, as a response to their<br />
de<strong>si</strong>res to introduce the human element in ecommerce. By offering the opportunity to the consumers to ask for details<br />
about the product bought, by directly answering to their questions, companies generate an increase in the level of<br />
satisfaction of the users of this application.<br />
Due to online bu<strong>si</strong>nesses’ de<strong>si</strong>re to be closer to their clients, u<strong>si</strong>ng instant messaging is more than welcome.<br />
Most of the ecommerce companies have introduced in their digital shop the facility to connect directly to one of the<br />
company’s consultants, by applications such as chat rooms or by u<strong>si</strong>ng the well-know Yahoo Messenger to<br />
communicate with the clients.<br />
4. Conclu<strong>si</strong>ons<br />
For one thing, the internet is used because people need to be informed – so companies should deliver<br />
accurate information to those interested – and on the other <strong>si</strong>de, due to people’s need to communicate. This<br />
interaction need should be explored by the company by u<strong>si</strong>ng the online marketing tools they have at their hand, for<br />
settling and consolidating long term relationships.<br />
More and more people are u<strong>si</strong>ng the internet for buying products and services. However, it is not at all<br />
recommended to use the web<strong>si</strong>te as a raw selling mean, just like a catalogue or a brochure. If the online marketing<br />
strategy con<strong>si</strong>sts only of expo<strong>si</strong>ng and selling products, the competition will be given only at the level of prices.<br />
Internet users can effortless search and compare prices in order to find the cheapest products available.<br />
The success of the strategy depends on the ability to correlate own purposes and interests to that of the<br />
public through valuable information and interaction, and technically by u<strong>si</strong>ng those online communication tools<br />
de<strong>si</strong>red by (potential) clients.<br />
The paper presents theoretical aspects concerning the main online marketing tools companies have at their<br />
hand for relating to their clients. This paper represents only the theoretical ba<strong>si</strong>s and it will be followed by an<br />
exploratory research where there are going to be analyzed the perceptions, attitudes and preferences of the internet<br />
users regarding how the companies employ these digital instruments for developing relationships.<br />
To sum up, the internet should not only be a place where the company presents itself and its products, but a<br />
means of changing occa<strong>si</strong>onal vi<strong>si</strong>tors into potential clients, and moreover to transform them into active customers.<br />
U<strong>si</strong>ng of the online marketing tools is imperious in managing customer relations because it helps the companies to<br />
better understand their clients, to deliver personalized services and to keep their clients.<br />
