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 …

Nash equilibrium is shown to exist for every game. In symmetric bimatrix games, our results imply the existence of a …

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 … communicate before choosing the investment time. We find that in groups of two players, communication increases cooperation and …

derived and the symmetric NE with the lowest expected gains is the maximin in symmetric strategies, which allows computation …
