中文摘要
本文研究高收入企业家的税收问题, 重点关注其通过财富随时间变化(跨期)而发挥作用的收入反应。我构建了一个纳入这一机制的税收公式, 并在一个量化模型中对其进行评估。结果表明, 从长期来看, 由财富变化驱动的收入调整对于产生较低的企业家最优最高边际税率至关重要。然而, 一旦将同时包含短期考量的转型动态纳入考虑, 企业家的最优最高边际税率便会变得与针对劳动者所建议的税率一样高。
Abstract
This paper studies the taxation of high-income entrepreneurs, with a focus on their income responses operating through wealth changes over time. I develop a tax formula that incorporates this mechanism and evaluate it within a quantitative model. The results show that income adjustments driven by wealth changes are crucial for generating a low optimal top marginal tax rate for entrepreneurs in the long run. However, when transitional dynamics that also include short-term considerations are taken into account, the optimal top marginal tax rates for entrepreneurs become as high as those suggested for workers.
