研究テーマ
- 1社会的選択理論
Social Choice Theory - 民主的な意思決定の背後にある論理構造を明らかにする.特に,アローの研究を嚆矢とする公理論的手法によって,社会的選好の合理性と人口構造の関連について研究を進めている.また,このような研究を通じて,社会の「幸福」「福祉」をいかにして測ることが可能であろうかという問題について考察している.
- 2産業組織論
Industrial Organization - 第1に,市場に公営企業と私企業の存在する混合寡占市場の研究に取り組んできた.特に貿易との関連について検討を進めた.第2に,自由参入市場におけるさまざまな競争政策の経済厚生に与える影響について研究を進めている.第3に,寡占市場における合併やリーダー企業の存在の経済厚生に対する含意を検討している.
- 3最適な経済組織構造と賃金プロファイル
Organization and Wage Profile - 限定合理的な個人の存在する状況において,いかに組織をガバナンスをすべきかという問題の検討を行っている.
- 4環境問題と持続可能性
Environment and Sustainability - 世代間公平性と持続可能性の関係を検討し,環境資源をどのように維持していくべきかを考察している.
- 5福祉と公正
Well-being and Fairness - 多次元的な福祉の概念を構成し,公正な社会の達成するための最適な制度に関する研究を行っている.
