Outline of Final Research Achievements

In this study, we conducted theoretical and empirical research on household and corporate behavior using macro-dynamic methods. We engaged in international collaboration, primarily in Europe, and completed papers on five themes: A) "Heterogenous Households and Macroeconomic Dynamics," B) "Monetary Policy and Heterogenous Firms," C) "Financial Friction and Heterogeneous Firms," D) "Trade Cost Shock and Dynamics of exported varieties and qualities" and E) "Natural disaster and Regional Interdependence". This international joint research has also expanded and developed our research network, enabling us to tackle new research challenges.
