This paper proposes a new communication protocol in coordination games with binary actions and Pareto-ranked equilibria … the payoff-dominant action in the second period if and only if everyone else waited. That is, efficient coordination is … introduction of the delay option significantly promotes efficient coordination …

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 …

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 … experimental findings from public goods and other coordination games, where communication always enhances efficiency and often …
