Migration and Fiscal Competition within a Union
NBER Working Paper No. 19282
We develop a stylized EU-type model of a union consisting of rich, capital-abundant and high productivity countries, and poor, capital-scarce and low productivity countries. We address two main issues: the efficiency of tax competition and the effect of factor mobility on the size of the welfare state. We identify a fiscal externality which impairs the efficiency of tax competition. We also demonstrate how capital mobility within the union strengthens the competition over migrants from outside of the union.
