Overview
The Japanese economy is facing various issues associated with sustainability. These issues include losing the scale-economy due to population decline, the increasing burden of social security due to population aging, and the need to contribute to international initiatives such as the SDGs. In this project, we will clarify the structure and impact of these issues on the sustainability of the Japanese economy from both theoretical and empirical perspectives, using a framework that takes into account heterogeneity across economic agents. We will also discuss measures to enhance sustainability, such as tax-reform and ESG investment.
