OPTIMAL TAXATION AND MARKET POWER
研究了当企业拥有市场势力时，最优所得税应如何调整，推导出依赖加成的税率公式，并量化了美国经济的最优税收方案。
Should optimal income taxation change when firms have market power? We analyze how the planner can optimally tax labor income of workers and profits of entrepreneurs. We derive optimal tax rates that depend on markups and identify four distinct components: the Mirrleesian incentive effect, the Pigouvian tax correction of the negative externality of market power, redistribution through altered factor prices, and reallocation of output toward the most productive firms. We quantify the optimal tax for the US economy and provide concrete proposals how to use income taxation to redistribute income while incentivizing production in the presence of market power.
