We consider a network game with strategic complementarities where the individual reward or the strength of interactions is only partially known by the agents. Players receive different correlated signals and they make inferences about other players' information. We demonstrate that there exists...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

We analyze a model of network formation with agents that belong to different communities and an endogenous cost structure. Both individual benefits and costs depend on direct as well as indirect connections. Benefits of an indirect connection decrease with distance in the network, while the cost...

We study the information flows that arise among a set of agents with local knowledge and directed payoff interactions, which differ among pairs of agents. First, we study the equilibrium of a game where, before making decisions, agents can invest in pairwise active communication (speaking) and...

The aim of this paper is to show that both location and race matter for explaining the high criminality rate in cities. In our model, blacks and whites are identical in all respects. However, if, for no economic but for extrinsic reasons, everybody (including blacks) believes that blacks are...

We consider two typed of cities. In the European one the amenities are located at the city-center ( like e.g. Paris or London) whereas in the American-type city the amenites are at the city-edge (like e.g. Detroit, Los Angeles). We first show that the unemploymed reside at the vicinity of the...
