-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 …

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

We analyze the performance of various communication protocols in a generalization of the Crawford-Sobel (1982) model of … possible that informative communication with one or both receivers is impossible in private, but possible in public. When the … by public communication with the flexibility provided by private communication and transmit more information to the …

This note reconsiders communication between an informed expert and an uninformed decision maker with a strategic … mediator in a discrete Crawford and Sobel (1982) setting. We show that a strategic mediator may improve communication even when … he is biased into the same direction as the expert. The mediator improves communication, however, only if some …

We propose a framework to analyze coalition formation with heterogeneous agents. Existing literature defines stability … conditions that do not ensure that, once an agent decides to sign an agreement, the enlarged coalition is feasible. Defining the … concepts of refraction and exchanging, we set up conditions of existence and enlargement of a coalition with heterogeneous …

It is well known that communication often serves as a facilitator for cooperation in static games. Yet, communication … can serve entirely different purposes in dynamic settings as communication during the game may work as a means for … investigates cooperation and non-binding communication in a two-stage game. More specifically, two treatments are considered: one …

We study communication in a two-player coordination game with Pareto-ranked equilibria. Prior research demonstrates … that efficient coordination is difficult without communication but obtains regularly with (mandatory) costless pre …-play messages. In a laboratory experiment, we modify communication by making the sending of messages optional and costly. Even small …
