| Outline of Final Research Achievements |
This project aims to understand the effects of communication on the play of games with focus on the difference in its timing. We experimented with major 2x2 games, such as prisoner’s dilemma, chicken game, coordination game, battle of the sexes, ultimatum game, under the condition with no communication, pre-play communication and post-play communication, and compared the experimental results.
To make the comparison meaningful, we adopted the message form in which the sender states her “hope” for a specific play of the receiver. Our findings are (1) even without communication, players have strong tendency to coordinate their choices, (2) sender sends a message such that she can maximize her payoff, while receiver almost perfectly predicts such messages, which means that players understand the incentive structure of the games very well, and (3) regardless of the timing of communication, the receiver is cautious about the self-interested behavior on the side of the sender.
