This paper develops a model of tax competition with three countries, which initially form a union where countries refrain from using different tax rates in different sectors of the economy. We study the impact of one country leaving the union. We show that the introduction of discriminatory...

How do countries compete for mobile tax base when they lack precise information on how tax rates affect the tax base? We present a multi-period version of a classic tax competition model in which countries set source-based taxes under incomplete information on the tax base elasticity. This...

This paper analyzes the implications of foreign firm ownership and international profit shifting through thin capitalization for corporate tax policy. We consider a model of interjurisdictional tax competition where the corporate tax serves as a backstop to the personal income tax, interest on...

I consider a continuum of multinational enterprises (MNEs), which differ in profitability. MNEs employ capital, shift profit to tax havens and may relocate their production facilities to other countries. Source countries provide public inputs and levy taxes. I derive optimal policy choices for...

We consider a world in which countries apply optimal taxes on mobile capital and savings (like in Bucovetsky and Wilson, 1991). Firms and savers may underreport income in order to avoid or evade taxation. We show that, even in the presence of underreporting, the equilibrium under tax competition...

We present a multi-period model in which countries set source-based taxes with- out having precise information how their and their neighbours' tax rates affect the tax base. Countries can learn from past experience and from observing their neighbours' outcomes and/or tax policy choices. We...
