Under the proposed information mechanism, consumers share their initial information with the members of their network … characterizing how many different pieces of information a network is likely to contain. This informativeness is crucial for the … results are robust to the introduction of sequential search and network segregation, but an increase in segregation decreases …

agents are myopic best responders. We develop a new network measure, the contagion threshold, that determines when a p … show that a p-dominant action spreads to the whole network whenever the contagion threshold of that network is greater or … the long run. This result implies that targeted contagion, a network-wide diffusion of actions initiated by targeting …

We analyze a model of endogenous two-sided network formation where players are affected by uncertainty in their … inefficient networks such as the empty network. On the other hand, it may include networks with unreciprocated, one-way links …, which comes with an efficiency loss as linking efforts are costly. We characterize equilibria under ambiguity and provide …
