Knowledge Exchange with a Shared Database

Knowledge Construction Lab


August 2007 – open-end


Budget resources of KMRC


In the context of web-based knowledge communication people can use new media in order to share information with other people. Since this kind of information exchange represents a social dilemma the involved people's willingness to pass on information is regularly rather low. This research project examines which factors influence people's experience and behavior in this information-exchange dilemma. In a series of experimental laboratory studies the following factors amongst others have been examined: bonus systems and contribution costs, behavioral recommendations and feedback, endowment heterogeneity, group awareness as well as various personality traits. In subsequent studies the scope will be broadened, and information exchange in online communities will be analyzed. Based on the social identity model of deindividuation effects the impact of anonymity and identifiability in the group context will be examined.
