We study how regional productivity differences and labor mobility shape optimal Mirrleesian tax-transfer schemes. When tax schedules are not allowed to differ across regions, productivity-enhancing inter-regional migration exerts a downward pressure on optimal marginal tax rates. When regionally...

Regional productivity differences provide scope for productivity-enhancing labor mobility. Redistribution reduces relocation incentives through higher taxes or lower transfers. Combining an intensive labor supply margin with an extensive, productivity-enhancing migration margin, we determine how...

We study the strategic incentives of regional governments to allocate their budget to public investment and to public consumption expenditures against the background of an incentive-compatible redistribution policy set by the central government. Regional investment changes the productivity...

We introduce cross-border shopping and indirect tax competition into a model of optimal taxation. The Atkinson-Stiglitz result that indirect taxation cannot improve the efficiency of information-constrained tax-transfer policies, and that indirect taxes should not be differentiated across goods,...

Restrictions on work hours are more important in countries with a large welfare state. We show that this empirical observation is consistent with the strategic effects of such restrictions in a welfare state in the context of optimal direct taxation in the tradition of Mirrlees (1971). Our...
