| Outline of Final Research Achievements |
We designed mechanisms that implement cooperation in social dilemma games without using punishments. First, we found that the approval mechanism that allows an approval stage after a dilemma game implements cooperation using the elimination of weakly dominated strategies, but does not implement it using subgame perfect Nash equilibrium. Second, the mechanism attains high cooperation rates from the first stage in experiments. Furthermore, the variants of the approval mechanism work very well in the class of quasi dilemma games including prisoner’s dilemma games and the public good provision games. Finally, we challenged to find solutions for dynamic dilemma games.
