-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 inclusion of verbal communication generates both …

We examine communication in a 2-player sequential public good game in which the leader has private information about … deciding whether or not to contribute. Without communication, the unique equilibrium is fully efficient. We study whether the … introduction of communication about returns can destroy efficiency. Communication can be precise (about the exact return), or vague …

We show that essentially every communication equilibrium of any finite Bayesian game with two players can be …. -- Bayesian game ; cheap talk ; communication equilibrium ; correlated equilibrium ; pre-play communication …

We study cheap talk communication in a simple two actions-two states model featuring ambiguous priors. First, we find … mixing by respectively S or R as embodying two different modes of ambiguous communication. Second, we find that for … implement his optimal decision rule and influential communication may be altogether impossible. We remark that these results …

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