present an experiment on a coordination game in which extrinsic random signals may generate sunspot equilibria. They measure … the risk-dominant equilibrium. -- coordination games ; strategic uncertainty ; sunspot equilibria ; irrelevant information …

impossible in finite games. Firstly, in coordination games, all players have the same preferences: switching to a weakly dominant … action makes everyone at least as well off as before. Nevertheless, there are coordination games where the best outcome … action. Secondly, the location of payoff-dominant equilibria behaves capriciously: two coordination games that look so much …

We study how punishment influences conditional cooperation. We ask two questions: 1) how does conditional cooperation … cooperation with punishment which leads to a decrease in conditional cooperation. The power to punish means more responsibility …
