Outline of Annual Research Achievements

本研究は、社会における企業や組織(一般に提携と呼ぶ)の安定性に注目し、どのような提携の構造が安定性を満たすのかについてゲーム理論的分析を行うことを目的とした。分析方法として、「コア」と呼ばれる安定性概念を中心に、その性質や存在条件を数理的に明らかにするというアプローチをとった。
一つ目の成果:提携の中での分配方法として「成果主義的」な方法と「年功序列的」な方法の折衷案を提案し公理的に特徴づけた。この論文は当該年度に査読付き国際誌で出版された。
二つ目の成果:コアの研究は、その先駆けである二人の研究者の名をとってBondareva-Shapley条件と呼ばれる条件を中心に行われていた。この条件は、その後、ゲームの性質の一つとして定着し「平衡性」と呼ばれた。しかし、彼ら以降の研究が平衡性にばかり注目することになってしまった。これを乗り越えるため、別のアプローチでコアの非空性を分析した。結果として、ゲームの「分解可能性」という性質を発見し、コアが存在するための新しい必要十分条件の提案に至った。この論文もまた当該年度に査読付き国際誌で出版された。
三つ目の成果:コア配分の中には、提携サイズの拡大に対して増加する利得配分が存在する。この性質はpopulation monotonicityとして知られる。分割関数形ゲームと呼ばれるクラスのゲームにおいて、この性質を満たす分配方法が存在する条件と構築方法を発見した。この論文は、年度明けの4月に、査読付き国際誌での出版が決定した。
