Three kinds of activities happen in a network: agents link or unlink; agents act; agents observe and learn. The existing literature on network formation, on network games and on monitoring and learning in networks studies each of these in isolation. We propose a framework in which these happen...

This paper studies adaptive learning in the class of weighted network games. This class of games includes applications like research and development within interlinked firms, crime within social networks, the economics of pollution, and defense expenditures within allied nations. We show that...

This paper studies information acquisition and use in network games. The network structure incorporates both strategic complements (positive links) and substitutes (negative links). An information-use game played on a correlation-adjusted network is derived. Equilibrium inefficiencies in both...

We address the problem of a planner looking for the efficient network when agents play a network game with local complementarities and links are costly. We show that for general network cost functions, efficient networks belong to the class of Nested-Split Graphs. Next, we refine our results and...

This paper considers a population of agents that are engaged in a listening network. The agents wish to match their actions to the true value of some uncertain (exogenous) parameter and to the actions of the other agents. Each agent begins with some initial information about the parameter and,...

Most network games assume that the best response of a player is a linear function of the actions of her neighbors; clearly, this is a restrictive assumption. We developed a theory called sign-equivalent transformation (SET) underlying the mathematical structure behind a system of equations...

We provide an overview and synthesis of the literatures analyzing games in which players are connected via a network structure. We discuss, in particular, the impact of the structure of the network on individuals’ behaviors. We focus on game theoretic modeling, but also include some discussion...

This paper investigates empirically the relationship between inflation, inflation volatility and output growth in the case of México using monthly data over the period 1993-2011. Specifically a bivariate GARCH-M model is estimated to test the hypotheses that inflation rates are directly related...

This paper develops a model of costly information acquisition by agents who are connected through a network. For a exogenously given network, each agent decides first on information acquisition from his neighbors and then, after processing the information acquired, takes an action. Each agent is...

In many economic situations, a player pursues coordination or anti-coordination with her neighbors on a network, but she also has intrinsic preferences among the available options. We here introduce a model which allows to analyze this issue by means of a simple framework in which players...
