摘要
In an unequal economy with inter-government objective inconsistency, this paper studies optimal non-linear central income tax with strategically designed non-linear regional income taxes. Using the variation approach, it derives a statistic-based optimal tax formula as a function of social welfare weights, regional income distributions, and elasticities of labor income. Unlike the traditional Mirrleesian tax, the optimal central income tax is limited to remedy the objective inconsistency. It is non-negative if the central government has a relatively higher obligation to redistribute. Introducing labor mobility activates the central income tax’s role as a Pigovian tax. The normative analysis suggests that the optimal tax authority may be fully centralized, decentralized, or combined. The numerical analysis for the U.S. implies a minor welfare influence of regional income tax. In contrast, the central income tax is crucial even if inter-region transfers are free. Last, enforcing a region-specific central income tax increases national welfare modestly.
