Outline of Final Research Achievements

In this study, we studied optimal monetary policy in a heterogeneous agent general equilibrium model. In most of the representative agent monetary models, it is well-known that the optimal nominal interest rate is zero. Here I assumed that individuals are heterogeneous in their initial wealth. I showed that in my model, the optimal monetary policy deviates from the zero-interest rate rule. This indicates that monetary policy has a re-distributive effect in my model with wealth inequality and the monetary redistribution is welfare improving.

Academic Significance and Societal Importance of the Research Achievements

当該研究は、望ましい経済政策は格差の程度にどのように影響を受けるのかについて説明したものであり、また、その結果も、貨幣供給量を増やすスタンスの金融政策が格差社会においては望ましくなるというわかりやすいものである。最近では社会における様々な格差に注目が集まっており、特に資産の格差についても注目が高まってきているといえる。この点で当該研究の社会的意義は少なくないものと考える。
