In … restricted cooperation this distinction should be defined by properties of the set of feasible coalitions. We characterize the … feasible sets in communication networks and compare them with feasible sets arising from hierarchies. …

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

We find that in groups of two players, communication increases cooperation and … how communication mitigates this free-riding problem in an investment-timing game. In our baseline investment-timing game …. If more investors invest at the same time, they share the costs. In the communication treatment, subjects can freely …
