【Titile】: Optimal Redistributive Capital Income Taxation with Endogenous Wage Inequality
【Abstract】: In a model with a continuum of imperfectly substituted labor inputs and capital inputs, this paper derives optimal (uniform and sector-specific) capital income tax formulas that (a) capture the key equity-efficiency trade-off; (b) are expressed in social welfare weights and empirical statistics; (c) and robust to the underlying structure of production. Taking a CES production function with sectoral capital intensity increasing with the sectoral wage as an example, we find that the optimal capital income tax rate is positive if and only if the elasticity of substitution between any two goods produced by different labors is higher than 1. When sector-specific capital inputs are introduced, it is found that the capital utilized by the poorest sector should be subsidized, while the capital belong to the richest sector should be taxed. The core intension of these results is that capital income taxation should be used to reduce relative wage inequality. At last, we present a numerical application with Chinese data. Concerning the transformation of tax structure in China, we try to answer, given the commodity taxation, whether the corporate income tax rate is too high and how to adjust the tax rate schedule of labor income taxation.
