研究室 名称 国際開発学研究室
詳細 人間社会はかつてない程相互依存しグローバル化しています。と同時に国家間、又は集団間同士での協力・協調無しに解決不可能な諸問題(特に国際紛争、貧困格差問題、持続可能性、資源エネルギー・地球環境問題等)が次々と起こっています。本研究室は、経済学・経営学の手法と実験的手法を駆使し、こうした問題の解決に向けた人々の行動変容・進化、そして、文化・社会の在り方に関する研究を行います。研究対象は日本と諸外国、特に問題が顕在化している発展途上国です。そうした諸外国と日本を対比させる事で競争と相互協力の在り方・文化的背景を理解し、問題解決の方策を科学的に研究していきます。
