The paper analyzes the role of the structure of communication - i.e. who is talking with whom - on the choice of … messages, on their credibility and on actual play. We run an experiment in a three-player coordination game with Pareto ranked … analysis of credibility, the subjects should communicate and play the Pareto optimal equilibrium only when communication is …

higher payoffs in the game when the talk is one-way as the truthful reports facilitate desired coordination. …

type-coordination property: it fully coordinates on the ex-post efficient pure Nash equilibrium when the players' types are … different. Type-coordination is also obtained in a partially revealing equilibrium in which only the High-type is not truthful …

Costless and non-binding pre-play communication (cheap talk) has been found to often be effective in achieving … uncertainty in the framework of a 2x2 coordination game, in which one choice leads to the same payoff regardless of the action of … the other person's play. Cheap talk is found to be effective, as there is much more coordination in both Signal treatments …

We study communication in ambiguous environments. Agents communicate individual decisions sequentially. Based on the …, the decisions differ no matter how long the communication lasts. Such persistent disagreements are precluded in Bayesian … frameworks endowed with a common prior. When communication is private and nobody is excluded from it, we show that ambiguity …
