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...

The OECD’s proposal for a global minimum tax (GMT) of 15% aims for a reversal of a decline of corporate tax rates. We study the revenue effects of the GMT by focusing on strategic tax setting effects. The direct effect from less profit shifting increases revenues in high-tax countries. A...

We study a fiscal policy model in which the government is present-biased, leading to an excessive public deficit. An optimally designed fiscal rule needs to trade off the benefit of committing the government to not overspend against the benefit of granting it flexibility to react to shocks to...

The controversy about sovereign debt cuts loomed prominently throughout crisis in the European Union (EU), as the EU legal rules were viewed to impose strict limitations on debt restructuring involving public creditors due to moral hazard concerns enshrined in the legal ban on bailouts. This...

The OECD’s proposal for a global minimum tax (GMT) of 15% aims for a reversal of a decades-long race to the bottom of corporate tax rates driven by competition over real investments and profit shifting to low-tax jurisdictions. We study the revenue effects of the GMT by focusing on the induced...

Under extraterritorial sanctions the sanctioning country extends its policies to trade of third countries with the sanctioned country. A prominent example is former US President Trump’s decision to leave the Joint Comprehensive Plan of Action (JCPOA), a multilateral agreement with Iran. The...

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...

Mobility of high-income individuals across borders puts pressure on governments to lower taxes. A central tenet of the corresponding textbook argument is that mobile individuals react to tax differentials through migration, and in turn immobile individuals vote for lower taxes. We investigate to...

Some governments have recently called for international accords restricting the use of preferential taxes targeted to attract mobile tax bases from abroad. Are such agreements likely to discourage tax competition or conversely cause it to spread? We study a general model of competition for...
