We introduce a simple two-stage game of endogenous network formation and information sharing for reasoning about the … optimal design of social networks like Facebook or Google+. We distinguish between unilateral and bilateral connections and … then we study how the network design and the utility specifications affect welfare. Surprisingly, we find that in general …

To address this gap, we simulate co-worker networks within firms from large-scale administrative data, for which we use …

The rise and popularity of online social networks is a recent phenomenon. In this study, we analyze the reasons and … mechanisms behind the collapse of an online social network (OSN), iWiW. Significant cascading mechanisms have been identified in … actors that started these cascades and abandoned the site early compared to others in their network. We contrasted …
