We introduce a simple two-stage game of endogenous network formation and information sharing for reasoning about the … then we study how the network design and the utility specifications affect welfare. Surprisingly, we find that in general … "babblers" or "friends", irrespective of whether the network is unilateral or bilateral, in equilibrium, targeted information …

We survey and synthesize models of network formation based on random graphs and stochastic processes. We organize the … homophilous linking on network structure. Finally, we discuss empirical and econometric issues based on stochastic network …

We consider a model of network interactions where the outcome of a unit depends on the outcomes of the connected units …. We determine the key network link, i.e., the network link whose removal results in the largest reduction in the aggregate … outcomes, and provide a measure that quantifies the contribution of a network link to the aggregate outcomes, which complements …

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 …

many well-known results from the contest literature can be obtained by varying the structure of the network. Our framework …

This paper proposes new centrality measures to characterise the 'key class', when agents in a network are sorted into … role-equivalent classes, such that its removal results in an optimal change in the network activity. The notion of role … theoretical applicability. Players in the network engage in a non-cooperative game with local payoff complementarities. We …

Interconnected banks are prone to the propagation of negative shocks. In a network with banks borrowing from each other …
