An equilibrium is communication-proof if it is unaffected by new opportunities to communicate and renegotiate. We … characterize the set of equilibria of coordination games with preplay communication in which players have private preferences over … the feasible coordinated outcomes. Communication-proof equilibria provide a narrow selection from the large set of …

Within-group communication in competitive coordination games has been shown to increase competition between groups and … lower efficiency. This study further explores potentially harmful effects of communication, by addressing the questions of … (i) asymmetric communication and (ii) the endogenous emergence of communication. Our theoretical analysis provides …

Costless pre-play communication has been found to effectively facilitate coordination and enhance efficiency in games … costly efforts. Allowing intra-group communication leads to more aggressive competition and greater coordination than control … treatments without any communication. On the other hand, allowing inter-group communication leads to less destructive competition …

Costless pre-play communication has been shown to effectively facilitate within-group coordination. However, in … costly efforts. We find that allowing within-group communication makes groups compete more aggressively. When only one group ….
