| Outline of Final Research Achievements |
In this study, I investigate the optimal labor income taxation with extensive labor margin and propose incentive compatible redistribution policies. In particular, I consider the optimal income taxation with human capital investment, the optimal age-dependent income taxation in a dynamic extensive margin, and the optimal income taxation with involuntary unemployment. I derive the optimal age-specific participation tax rate in the dynamic extensive model. Our numerical simulations suggest that a negative participation tax should be restricted to young households. With human capital investment, the role of the capital income tax is to promote human capital investment and mitigate the labor income tax distortions on it.
