Understanding The Different Facets Of Relationships In Social Media For The EnterpriseDaly, Elizabeth M.; Ehrlich, KateOrganizations and NetworksOrganizations, Social MediaSAT.PM2Social media enables a variety of relationships when deployed in an enterprise including social relationships, colleague relationships and information discoveryrelationships. Social relationships involve reciprocated connections that can include both work related and personal interactions. Colleague relationships arelikewise reciprocated and focus more on business related content. Information discovery relationships may in contrast be asymmetric, where users may gainnew knowledge through a following connection or benefiting from content contributed by other users without any action require on the part of the expert.Information seeking relationships have a different property where the user may require some action on the part of the informant such as a response to arequest for information. The rich social environment in the enterprise enables us to understand the different facets of these symmetric and asymmetricrelationships and their underlying purpose. In this talk we present the results of a study that used data from social media usage in an enterprise to extractrelationships based on social connections, collegial connections and information discovery connections. We examine the properties in order to helpunderstand the differences between these relationships and highlight the important role social media can play in not only enabling these relationships, butsupporting them.Underwriter Peer Network And Ipo PerformanceChuluun, Tuugi; Eun, CheolBusiness & Entrepreneurial NetworksInter‐organizational Networks, Financial Networks, Securities Markets, InformationWED.PM2We examine how underwriter peer network affects the performance of initial public offerings (IPO) using measures from social network analysis. IPO refers tothe first issuance of a company’s common stocks to the public, and information production is one of the key functions of underwriters in this process. Weexplore the impact of underwriter peer networks on a sample of U.S. IPOs issued between 1974 and 2007. The network measures are constructed using tiesthat underwriters form with each other when they work together in the syndicates of public securities issued in the U.S. during 1970‐2007. Our results showthat IPOs are more likely to experience offer price revision when they are underwritten by book managers with large networks, ties to well‐connectedunderwriters and bridging positions between other underwriters. The likelihood of offer price revision also increases when the book managers’ networksinclude partners with similar geographical or industrial specialization and display greater interconnectedness among the partners. These finding imply thatmore networked book managers significantly contribute to pre‐IPO price discovery. All these network characteristics also lead to higher post‐IPO stock returns.Finally, the effects of book manager networks are greater for younger firms with higher information asymmetry and during periods with lower deal volume.
