network structure and we examine equilibrium selection. Specifically, actions are either strategic substitutes or strategic … complements, and participants have either complete or incomplete information about the structure of a random network. Since … for reduced exposure to loss, and 2) uncertainty about the network structure makes it considerably more difficult to …

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 defining the Nash equilibrium. By applying our theory, we reveal that many …

are connected according to an undirected graph, the social network, and have the choice between two actions: either to … network. (2) Average inclination governs collective adoption behavior. (3) Initial inclinations determine the critical mass of … network and other parameters. Given the complexity of the system we use a standard technique for estimating the solution …

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 find that, depending on the specification of the network cost function …

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 …

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 … are linked and (perhaps) from a public signal. We define a repeated network game and an equilibrium of this game. An …
