Heretofore, I have been studying the cause of volatility in world economies and financial markets, devoting myself to theoretical works, and applying game theory to explain the cyclical dynamics of a given economy. Recently, I have been applying evolutionary game theory to bank competition models.
What I am currently interested in is behavioral finance. To the extent of my knowledge, it encompasses two academic arenas: discovering new phenomena that cannot be explained by traditional financial theory, and providing theoretical explanations based on psychological biases to such phenomena. I am interested in the latter theoretical work. Finding the fundamental causes of these psychological biases seems particularly interesting.
(Subject of research)
Theoretical and empirical study on the changes in the lending behavior by banks

12 87-104, 2018 Peer-reviewedInvitedIn this paper, we introduce grit and mindset research, two streams of research in psychology, and discuss their implications for labor productivity improvement and their application to behavioral economics. In grit research, grit is defined as "perseverance and passion for long-term goals," while mindset research explores our two contrasting mindsets: the growth mindset and the fixed mindset. Both grit and mindset research indicate that abilities acquired by our efforts are much more important than we expected, and mindset is strongly associated with the process of acquiring new abilities. These fields of research suggest the low level of labor productivity in Japan might come from a cognitive bias toward a fixed mindset, which emphasizes innate talent rather than acquired abilities.

行動経済学, 10 S29-S32, 2017<p>本研究は，信頼関係やネットワークを包含する「ソーシャル・キャピタル」の概念を用いながら，小さい組織や団体におけるコミュニティの状態を測定する方法の開発を試みる．日本国内の1600以上のNPO団体に所属するメンバーを対象に，社会心理学における質問紙調査法によって，所属団体に対する意識を調査した．回答結果を因子分析した結果，コミュニティの状態を測るうえで重要な意識として3つの因子，「理念共感と貢献意欲」，「自己有用感」，「居心地の良さ」が抽出された．これら3つの因子を説明変数とした回帰分析によって，これらの因子は「コミュニティへの愛着」，「主観的幸福感」，「主観的健康感」に，統計学的に有意なプラスの影響を与えることが確認された．この研究を応用することで，目には見えないNPO団体内の課題を可視化することが可能になり，より効果的なNPO団体のマネジメントが可能になるものと期待される．</p>
