本文在一个具有不完全替代劳动力和内生技能溢价的连续统模型中，导出了作为社会福利权重和一小组可估计统计量的函数的最优税收公式。它首先表明，差分资本税，资本的技能溢价的影响的基础上，是可取的，即使在稳定状态下，而非线性资本税是不可取的可加性分离的效用函数。然后，它探讨了统一和部门特定的资本所得税（UCIT和SCIT），与一个部门对应的一种类型的劳动者。数值应用于美国税收提供了一个倒U形的SCIT率和部门工资之间的关系。最高收入部门的最优SCIT税率随着部门产品之间的替代弹性而增加，相当于45.9%的净回报税。从UCIT到SCIT的改革大大缩小了前10%与其他人之间的工资差距。它特别有利于中等收入者，他们的工资增长高达3.8%。由于生产效率低下，从UCIT转换到SCIT意味着较小的福利收益（消费当量为0.07%~0.22%）。
Abstract In a model with a continuum of imperfectly substitutable laborers and endogenous skill premiums, this paper derives optimal tax formulas as functions of social welfare weights and a small set of estimable statistics. It first demonstrates that differential capital tax, based on capital’s effect on skill premiums, is desirable even in the steady state, while nonlinear capital tax is not desirable under an additively separable utility function. It then explores both uniform and sector-specific capital income tax (UCIT and SCIT), with a sector corresponding to a type of laborer. Numerical application to U.S. taxation delivers an inverted U-shaped relationship between the SCIT rate and sectoral wage. The optimal SCIT rate on the top-income sectors increases with the elasticity of substitution between the sectoral products and amounts to a net return tax of 45.9 % . Reform from UCIT to SCIT compresses wage gaps between the top ten percent and others considerably. It especially favors the median-income individuals whose wages are increased as high as 3.8 % . Due to production inefficiency, switching from UCIT to SCIT implies small welfare gains ( 0.07 % ~ 0.22 % in consumption-equivalent terms).
