commitment. By allowing the principal to use general communication devices we overcome the literature's common, but overly … restrictive focus on one-shot, direct communication. In addition, general communication devices solve two fundamental problems of … the message spaces of the communication device. An example illustrates our arguments and the suboptimality of one …

Communication has been regarded as one of the most effective devices in promoting team cooperation. But asymmetric … communication sometimes breeds collusion and is detrimental to team efficiency. Here, we present experimental evidence showing that … excluding one member from team communication hurts team cooperation: the communicating partners collude in profit allocation …

Case studies of cartels and recent theory suggest that repeated communication is key for stable cooperation in … environments where signals about others' actions are noisy. However, empirically the exact role of communication is not well … understood. We study cooperation under different monitoring and communication structures in the laboratory. Under all monitoring …

. 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 …
