Factor supply increases (depresses) output for many of the same reasons that the government spending multiplier might be less (greater) than one. Data from three 2008-9 recession episodes - the labor supply shifts associated with the seasonal cycle, the 2009 federal minimum wage hike, and the...

We provide a model for analyzing effects of the tax system and spending programs on the determination of government spending and taxpayer welfare and show that tax system or spending program which is suboptimal from a Ramsey point of view can improve taxpayer welfare because the system creates...

It is often argued that tax competition may lead to a "race to the bottom". Such a race may hold indeed in the case of the pure case of factor mobility (such as capital mobility).

We develop a political-economy model of economic union and compare the competion regime to the coordination regime. Key policy differences emerge between the two regimes: concerning the generosity of the welfare state and the skill composition of migration. We argue that the differences between...

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...
