Outline of Final Research Achievements

We design a repeated public goods game in which a subject's contribution does not diminish over time. Specifically, a group receives a rebate, which is evenly distributed among all subjects in the group, if the collective contribution of the group becomes larger than a threshold. Contrary to previous literature, we find that subjects do not reduce contribution over time if a threshold is set. Subjects tend to act more responsibly and keep contributing to achieve the threshold contribution level.

Academic Significance and Societal Importance of the Research Achievements

支払うコストを負担しなくても、その財やサービスを利用できる、いわゆるフリーライダー問題は公共財あるいは共有地で起こると言われている。公共財におけるフリーライダー問題を解決するためには、公共財の過少供給を行う人々に対して制裁を課したり、その人々を一般に公表したりするなど、いわゆる恐怖心や羞恥心を与える制度が有効であることが実験を介して明らかにされてきている。しかしながら、このような制度では、人々の不満が高まり、フリーライダー問題を根本から解決したことにならない。そこで、本研究では、公共財におけるフリーライダー問題を解決するため、人々が恐怖心や羞恥心を抱かずに協力しあうような制度を発見した。
