The same activities often exert externalities that cumulate in "stocks" affecting agents … network of social relations, as agents display strategic substitution with distance-two neighbors. We show that behavior is … predicted by a weighted Bonacich centrality index, with weights accounting for distance-two relations. We find that both maximal …

The flow of information is related with network centrality …Imperfect private monitoring in an infinitely repeated discounted Prisoner’s Dilemma played on a communication network …’s history throughout the network. The delay in receiving this information requires the players to be more patient to sustain the …

Since the seminal contribution of Jackson & Wolinsky 1996 [A Strategic Model of Social and Economic Networks, JET 71 …, 44-74] it has been widely acknowledged that the formation of social networks exhibits a general conflict between … general results that relate situations of positive externalities with stable networks that cannot be “too dense” in a well …

We study (anti-) coordination problems in networks in a laboratory experiment. Partici- pants interact with their … neighbours in a fixed network to play a bilateral (anti-) coordination game. Our main treatment variable is the extent to which … players are heterogeneous in the number of connections (neighbors) they have. Other network characteristics are held constant …

We analyze the situation when the tragedy of the commons is embedded in a network of users and … exists a unique equilibrium. But when the users have concave values, the network structure matters. The exploitation at each …

We develop a model of endogenous network formation in order to examine the incentives for R&D collaboration in a mixed … oligopoly. Our analysis reveals that the complete network, where each firm collaborates with all others, is uniquely stable … under strong market rivalry a conflict between stable and efficient networks is likely to occur.

We examine how three different communication processes operating through social networks are affected by homophily … friendship networks from the Adolescent Health dataset. …

We consider any network environment in which the “best shot game” is played. This is the case where the possible … 1 is minimal. To find such an equilibrium is a very hard task for any non-trivial network architecture. We propose an … network structure is unknown to the social planner. …
