| Outline of Final Research Achievements |
In this study, we investigated how sanction-reward and punishment- works to solve social dilemma in terms of group size and centralized institutions. As for peer reward and punishment, the results suggest that sub-grouping, that is, the situation in which the members one can sanction is limited, cause the failure of cooperation in large-scale groups. As for centralized punishment institutions, the results suggest that the second-order punishment, that is, the punishment to the member who does not support the institution, is important to maintain cooperation in large-scale society. In conclusion, this study shows that peer reward is effective in a small-scale society and centralized punishment institution is effective in a large-scale society.
