| Outline of Final Research Achievements |
Ogawa, a principal investigator, analyzed the optimal income tax problem under a tax revenue constraint in a model where educational and entrepreneurial investment affects the ex post distribution of productivities. Incorporating external educational facilities into the model, we also examined the effects of a subsidy for using the facility.
Horii, a co-investigator, examined income distribution and education from the perspective of economic growth. In one study, he clarified a mechanism through which the risk attitude of consumers changes according to a learning process. In another study, he developed a theory of economic growth using a realistic value for the elasticity of substitution between labor and capital, which is closely related to the labor income share of the GDP.

| Academic Significance and Societal Importance of the Research Achievements |
最適課税分析では、所得税が将来の子供の生産性・質を高めるために有効であることが分かった。さらに、教育投資のための外部施設の充実や外部施設利用への補助が、幅広い条件の下で、家計への直接補助よりも有効であることを明らかにした。
動学分析においては、従来は技術的理由により、ほとんどの新古典派成長モデルでは、労働分配率が一定となるコブ・ダグラス生産関数を使わざるを得なかった。新しい定理の証明により、より柔軟な定式化が可能になり、今後、公平性の分析を柔軟に行えるようになる。
