We study the nonlinear taxation of internationally mobile workers in general equilibrium. Contrary to conventional wisdom, in general equilibrium, migration lowers the bottom tax rate but raises the top tax rate, making the optimal tax system more progressive and moving tax rates closer to those...

We develop a theory of economic disintegration with both endogenously formed tax and trade policies. We show very generally that, contrary to conventional wisdom, a country’s disintegration from an integrated area leads to a deeper integration inside the area. Similarly, the departure of a...

Wealthier households obtain higher returns on their investments than poorer ones. How should the tax system account for this return inequality? I study capital taxation in an economy in which return rates endogenously correlate with wealth. The leading example is a financial market, where the...

Economic disruptions generally create winners and losers. The compensation problem consists of designing a reform of the existing income tax system that offsets the welfare losses of the latter by redistributing the gains of the former. We derive a formula for the compensating tax reform and its...

The paper analyzes the labor market effects of globalization when foreign market entry is costly and risky. With flexible labor markets, a fall in foreign market entry cost tends to generate more income inequality. By contrast, when workers cannot easily switch industries and wages are...

Despite the well-developed empirical literature on local tax competition, little is known about the actual spatial structure of inter-municipal competition. Assuming that competition takes place only among neighbours (as in the empirical literature) is at odds with the theoretical approaches...

Legal conflicts between multinational firms and host governments are often decided by international arbitration panels - as opposed to courts in the host country - due to provisions in international investment agreements known as Investor State Dispute Settlements (ISDS). Critics fear that ISDS...
