Outline of Final Research Achievements

The researches we conducted analyze the effectiveness of two centralized punishment institutions in raising the efficiency and the cooperation rates in social dilemma under different information conditions. In the punishment institutions considered, there is a required level of cooperation. In the absolute punishment institution, all individuals who cooperate less than required is punished, where as in the relative punishment institution, among those who cooperated less than required, only the minimum cooperator is punished. In the existing study, it had been shown that relative punishment institution yields the same or higher cooperation and efficiency than the absolute punishment institution. However, this study showed that the effectiveness of the punishment institution is sometimes reversed when the information condition is changed.
