| Outline of Final Research Achievements |
This project uses a repeated game to investigate cooperation between countries regarding an international public good provision. Specifically, we focused on dividing the burden in the cooperation phase to promote cooperation, when withdrawal from an agreement is the only possible punishment because national sovereignty is respected.
I have written papers on international environmental agreements on emissions reductions and international cooperation on refugee resettlement. In the former case, given the target emission reduction amount, we derived an emission allocation that minimizes the discount factor making the agreement self-enforcing. The latter study considered negotiated and agreeable quotas, focusing on an equilibrium that relieves all refugees who wish to be resettled.

| Academic Significance and Societal Importance of the Research Achievements |
国際環境協定の研究では、先進国に有利なため政策現場で批判されることの多い負担の分け方であるgrandfatheringの一つの効能を示したことに社会的意義があると考える。また、Association of Environmental and Resource Economistsの学会誌に掲載されたことは、この研究の学術的意義を表している。
難民の第三国定住の研究は、動学ゲームを用いた研究が皆無であった。しかし、難民の第三国定住は日々継続的に続く問題であり、動学ゲームによる分析こそ求められていると考える。この問題を繰り返しゲームで分析した学術的、社会的意義は大きいと考える。
