We examine a new class of games, which we call social games, where players not only choose strategies but also choose … players in different roles, among other things. We also examine finite repetitions of games where players may choose to … rematch in any period. Some equilibria of fixed-player repeated games cannot be sustained as equilibria in a repeated social …

In this paper we introduce an extension of the model of restricted communication in cooperative games as introduced in … Myerson (1977) by allowing communication links to be directed and the worth of a coalition to depend on the order in which the … players enter the coalition. Therefore, we model the communication network by a directed graph and the cooperative game by a …

A new solution is presented for transferable utility games with graph communication where the cooperation possibilities … introduced, under which the value is guaranteed to be an element of the core. For games with complete graph communication the … connected set in the given graph. To determine the payoff for each player, a single-valued solution, the communication tree …

We study cooperative games with communication structure, represented by an undirected graph. Players in the game are …-convexity is weaker than convexity. For games with a cycle-free communication structure, link-convexity is even weaker than super-additivity … proposed for this class of games. Given the graph structure we define a collection of spanning trees, where each spanning tree …

Herings et al. (2008) proposed a solution concept called the average tree solution for cycle-free graph games. We … provide a characterization of the average tree solution for cycle-free graph games. The characterization underlines an … (Myerson, 1977) for cycle-free graph games …

In this paper we consider cooperative games in which the possibilities for cooperation between the players are … restricted because communication between the players is restricted. The bilateral communication possibilities are modeled by … means of a (communication) graph. We are interested in how the communication restrictions influence the game. In particular …
