models of communication and hierarchy restrictions in cooperative games, compare different network structures with each other …. Two well-known network structures are hierarchies and communication networks. We give an overview of the most common … and discuss network structures that combine communication as well as hierarchical features. Throughout the survey, we …

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 …

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 …

In this paper we study cooperative games with limited cooperation possibilities, represented by an undirected cycle …-free communication graph. Players in the game can cooperate if and only if they are connected in the graph, i.e. they can communicate …

We introduce an efficient solution for games with communication graph structures and show that it is characterized by … communication graph the total payoff to the players of this component in the game itself to the total payoff of these players when …

We implement our model in a laboratory experiment utilizing a … 2x2 design, where we vary the availability of communication and the number of agents. We find that communication …
