Outline of Final Research Achievements

In this study, we analyze bargaining. In baragining, negotiators have to decide their distribution of the profit which can be obtained by their cooperation.
Especially, this study analyze the situations where negotiators can use arbitration and can sign to a long-term contract by using non-cooperative game theory.
We obtain the following two results. First, we show that, in the case that negotiators can use arbitration, whether they use the arbitration depends on the cost of using it. Second, we show that, in the case that the profit obtained by their cooperation have some uncertainty, then each negotiator may demand large proportion of the profits in bargaining even if a small profit is realized with a high probability.

Academic Significance and Societal Importance of the Research Achievements

本研究の目的は、企業や国家間の交渉プロセスをモデル化し、交渉における戦略や交渉方法の適切なルールについての新たな指針を与えることである。本研究では、仲裁がある状況や長期契約が可能な状況を非協力ゲーム理論で分析することにより、現実で観測される交渉者の行動や戦略について理論的な基礎づけを行うことができた。
このような理論的な分析により、現実の仲裁制度を効果的に設計することや、長期契約における交渉者の行動要因についてより詳細な分析が可能となる。この点が本研究の学術的・社会的意義である。
