Abstract:	The recent rise in economic inequities evoked proposals for reforms of current tax systems towards more redistribution. Most of the theoretical and empirical research in public economics studies individuals’ behavior, taking pre-tax wage and return rate differentials as inherently given. However, this assumption of exogenous skill differences is inconsistent with the cross-sectional dynamics in inequality and the insights from the modern literature on labor and financial economics. Wages and return rates are, to some extent, economic outcomes, for example, determined by effort, migration, portfolio choices, or general equilibrium externalities. In this thesis, I make progress toward understanding redistributive policies under endogenous pre-tax incomes. In Chapter 1, I study capital taxation when the heterogeneity in return rates endogenously forms. Chapter 2 derives the optimal labor income taxation with endogenous pre-tax wages and migration responses. Finally, Chapter 3 studies the effects of business taxes, another instrument of redistribution, on the endogenous profit margins of internationally mobile firms.
