Heterogeneous Firms, 'Profit Shifting' FDI and International Tax Competition

We develop a stylized model of international tax competition between a large country and a tax haven. In the large country, firms in a monopolistically competitive industry generate positive profits which can be taxed by the government. Firms have heterogeneous productivity levels and can choose to undertake `profit shifting' FDI in order to benefit from lower tax rates abroad. We find that economies with a low degree of firm heterogeneity and a high degree of monopolistic market power are less affected by international tax competition. They face lower out flows of the tax base and can set higher tax rates.
