Outline of Research at the Start

社会は多くの経済主体から構成され,それらの行動は互いに影響しあっている.多くの場合において,その相互作用の範囲は社会全体には及ばずに局所的なものとなっている.主体間の相互依存関係はネットワークを定義し,それに利得構造を加えたものは「局所相互依存ゲーム」と呼ばれる.本研究は,「どのようなネットワーク構造と利得構造のもとで,どのような行動パターンが実現するのか」という問いに答えるために,局所相互依存ゲームの理論の進展を図り,その成果を空間経済学の文脈に応用して新たな知見を得ることを目指すものである.

Outline of Final Research Achievements

The purpose of this project has been to enhance our understanding, from a unified perspective based on game theory, on strategic interactions through space, time, and information. I obtained new results and insights on the relationship between spatial agglomeration of industries and economic growth, continuous limit approximation of finite-player stochastic games, and the robustness of equilibria to incomplete information. These have been published or reported in international referred journals and conferences.

Academic Significance and Societal Importance of the Research Achievements

多地域経済成長の分析については,資本蓄積および立地選択に関する通時的意思決定を取り入れた理論モデルを構築し,均衡の大域安定性を厳密に分析することができた.有限人プレイヤーの確率ゲームの連続極限近似の分析については,やはり forward-looking なプレイヤーを扱って均衡集合一様に成り立つ近似定理を示すことができた.不完備情報に対する均衡の頑健性については,前回の研究課題をより精緻化する結果を得ることができた.
