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 …

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 pre-play communication in which players have private preferences over … the feasible coordinated outcomes. Communication-proof equilibria provide a narrow selection from the large set of …
