研究内容
経済活動において、金融市場は大きな役割を果たしています。例えば、企業の資金調達、家計の貯蓄・資産運用、あるいは様々なリスクに対する保険の提供などの役割です。私の関心は、経済全体をまとめてみたマクロ経済の活動に、この金融市場が果たしている役割を分析することにあります。具体的に言えば、金融市場の発展が所得分配や経済の安定性にどのような効果を及ぼすのかを分析しています。また、経済の発展過程においては、それまで使われていた技術が別の技術に置き換えられることがしばしばあります。このような技術の切り替えが生じるメカニズムを考慮したマクロ経済モデルを構築することによって、技術の変化が経済の発展パターンにどのような影響をもたらすのかについても分析を進めています。
