PB - National Bureau of Economic Research N1 - August 2013; Hardcopy version available to institutional subscribers N2 - 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 UR - https://www.nber.org/papers/w19282 UR - http://dx.doi.org/10.3386/w19282 ER -
