Outline of Research at the Start

集計的ゲームに関するシェア関数アプローチを、公共財の自発的供給および集団コンテストに関する問題に適用することで、集団構成員間の異質性が集団全体のパフォーマンスや構成員たちの厚生に及ぼす影響について、理論的に明らかにする。具体的な目標は以下の通りである。
〔1〕集団間競争から生じる集団利益分配パターンの同定、〔2〕災害リスク低下への自発的貢献モデルの構築、〔3〕生産・収奪モデルの集団間紛争への拡張、〔4〕複数貢献手段を持つ異質な構成員による集合行為モデルの構築を試みる。

Outline of Final Research Achievements

The theory of group contests considers the contests by groups suffering from the collective action problems. It is applicable to various economic and political competitions in society: lobbying by interest groups, competition by sports teams in a sports league, R&D competition by firms, and so on. This research tries to introduce many kinds of heterogeneity (abilities, roles in an organization, attitudes to risk) and complementarity of the members in a group to the models of group contests and examine the implications. As the most important product, a paper on the group contest in which competing groups can contain internal structures is published, which derives a simple characterization of the team-effort-maximizing prize-sharing rule.

Academic Significance and Societal Importance of the Research Achievements

集団コンテストのモデルは、ロビー活動、スポーツリーグ、技術開発競争など、様々な経済的政治的競合過程の分析に用いることができる。公刊論文で示された、複数の内部集団を包含した構造を有する集団によるコンテストのモデルは、こうした競合過程にある集団の組織構造と報酬体系に関する議論を一層精緻で豊かなものにする。また、集団への帰属意識や貢献能力の異なる構成員の間の、業務割り当てに関するモデル分析への展望も開くものである。
