Title Second thoughts of social dilemma in mechanism design
Author Tatsuyoshi Saijo
Abstract This paper shows that second thoughts are not an innocent device in our daily life, but is human wisdom that plays an important role in resolving problems such as social dilemmas. We design a simple mechanism to achieve Pareto efficiency in social dilemmas, and then compare the performance of this mechanism with and without second thoughts. First, second thoughts change the payoff structure of the game in favor of cooperation. Second, this mechanism is robust even when players deviate from a payoff maximizing behavior.
