主题:Indirect Taxation, Market Power and Social Efficiency
摘要:This paper revisits the old topic of optimal indirect taxation. Consider an economy where all commodities are taxable. Tax revenue is viewed as the “rent” of governmental coercion power, and gross profit as the “rent” of market power. A government maximizes consumer surplus conditional on raising certain tax revenue and gross profit. I first characterize the social optimal resource allocation where a planner makes decisions for the government and consumers. Then I show that the government can realize the social optimal outcome through an indirect tax structure. The optimal tax structure should equalize the after-tax Lerner indexes of all commodities. I also show that the optimal tax structure generally results in welfare gain rather than deadweight loss when labor supply is sufficiently inelastic.
