This paper characterizes geometrically the set of all Nash equilibrium payoffs achievable with unmediated communication …

We study the effects of communication in an experimental tournament between teams. When teams, rather than individuals … communication in such situations may have ambiguous effects on effort choices. Communication within teams may promote higher efforts … by mitigating the internal free-rider problem. Communication between competing teams may lead to collusion, thereby …

: communication, and punishment (allowing subjects to engage in costly reductions of one another’s earnings after learning of their … contribution decisions). We find that communication increases contributions more than punishment, and, taking into account the cost … of punishment, only communication significantly increases subjects’ earnings and thus efficiency.

-play communication: numerical (tabular) only, and verbal and numerical. We find that either kind of pre-play communication increases … trusting, trustworthiness, or both, in inter-subject comparisons, but that the inclusions of verbal communication generates …

The paper studies the role of communication in facilitating collusion. The situation of infinitely repeated Cournot … collusive output levels or a 'downward' demand shock. The firms choose between tacit collusion and collusion with communication …. Communication implies that the firms meet and exchange information about past outputs and is assumed to be the only legal proof of …
