| 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 robustness of equilibria to incomplete information, the relationship between spatial agglomeration of industries and economic growth, and continuous limit approximation of finite-player asynchronous-move stochastic games. These have been published or reported in international referred journals and conferences.

均衡の情報頑健性の分析については，(2戦略の範囲で) 多人数のプレイヤーのクラスではじめて必要十分条件を与えることができた．多地域経済成長の分析については，(ポテンシャル関数の存在を保証するある種の対称性の仮定の下で) 将来期待の下で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．
