| Outline of Final Research Achievements |
The purpose of this research project is to quantitatively understand the relationship between time trends in economic inequality and monetary policy in Japan. Raising or lowering interest rates by the central bank affects our lives in various ways, including asset income and corporate profits. However, it has not been well understood what the specific impact is and to what extent. In this study, we used the Family Income and Expenditure Survey and the National Survey of Family Income and Expenditure to estimate the trends of inequality in the Japanese economy since the 1980s, and clarified the relationship between the inequality and monetary policy. The results revealed that monetary policy (lower interest rates) raises economic inequality, especially the labor income of working households. However, we also found at the same time that the impact of monetary policy on inequality has weakened in recent years.
