Open collaboration (OC) relies on a large number of goal-oriented yet loosely coordinated participants, who interact to cre-ate a product (or service) of economic value, which is made avail-able to contributors and non-contributors alike. Indeed, OC will have significant economic as well as social impact[24,2,20]. Schol-ars in social and behavioral science and economics have started to address the emerging phenomena from different angles and present relevant empirical insights. For example, research draw-ing upon network theory tackles structural characteristics of large OC networks and also presents new insights in the role of author-ity, reputation, and trust in OC[28]. Contributions in organizational studies and information systems have revealed deeper insights into the factors that motivate individuals to contribute, and the social value they might have[13].
