Dynamics <strong>Network</strong>s As Exchange Of Heterogenous In<strong>for</strong>mationBerea, Anamaria; Tsvetovat, Maksim<strong>Network</strong>s and Economicsendogenous network, heterogeneous in<strong>for</strong>mation, in<strong>for</strong>mation interdependenceFRI.PM2Economic theories of in<strong>for</strong>mation focus on the peculiarities of in<strong>for</strong>mation as an economic good and on asymmetric in<strong>for</strong>mation problems in a market setting,treating in<strong>for</strong>mation as a homogeneous good. This paper treats in<strong>for</strong>mation as a heterogeneous agent from a person’s subjective perspective and uses socialnetwork analysis and marginal cost‐benefit analysis to discover and interpret interesting emergent topologies. The analysis is per<strong>for</strong>med on a bi‐modalnetwork of people and in<strong>for</strong>mation employing a bottom‐up approach with respect to ego‐networks of people and a top‐down approach with respect toin<strong>for</strong>mation embedding. The in<strong>for</strong>mation agent is analyzed under its’ semantic dimension and represents both nodes in the interdependence network andedges in the people network. In order to do this, a clear distinction between “noise” and “meaningful in<strong>for</strong>mation” has to be made. The rules of edge creationand destruction follow the basic economic rules of exchange. One important finding is that the embedded network of in<strong>for</strong>mation can significantly alter thestrength of the edges in the network of people, regardless of the initial topology.Dynamics Of Friendship <strong>Network</strong>s And Academic Per<strong>for</strong>mance: A Comparison Between Two Student Cohorts Be<strong>for</strong>e And After Education Re<strong>for</strong>m In TaiwanChang, Ming‐Yi; Snijders, Tom; Wu, Chyi‐InFriendship networksAdolescents, Multilevel <strong>Network</strong>s, Selection And Influence, Friendship <strong>Network</strong>WED.PM1For adolescents in Taiwan, in their junior high school years, to advance to a better high school <strong>for</strong> the diploma, students have to be competent enough. This isassessed by the Entrance Exam. In the past, exam stress brought lots of educational and adaptation problems <strong>for</strong> pupils. An educational re<strong>for</strong>m wasimplemented in order to mitigate the stress of education competition. To examine how this re<strong>for</strong>m has affected students' social and academic lives in juniorhigh schools, this study tests whether it has changed the pattern of co‐evolution of friendship networks and students' academic per<strong>for</strong>mance. The data consistsof 2534 adolescents in 41 schools from two different youth panel datasets collected be<strong>for</strong>e and after the educational re<strong>for</strong>m in Taiwan. Actor‐oriented models,as implemented by RSIENA, will be used to answer the research questions. Further discussions will be provided about the effects of education re<strong>for</strong>m inTaiwan.
