This paper presents a general-equilibrium model where human capital investment increases specialization and exposes skilled workers to region-specific earnings risk Interjurisdictional mobility of skilled labor mitigates these risks; state-contingent migration of skilled labor also improves...

We analyze models with interjurisdictional spillovers among heterogeneous jurisdictions, such as CO2 emissions that affect the global environment. Each jurisdiction's emissions depend upon the local stock of capital, which is interjurisdictionally mobile and subject to local taxation. In...

Trade in a Tiebout EconomyThis paper explores both the positive and normative aspects of interregional commodity trade in a "Tiebout e conomy," i.e., a many-region economy with perfect labor mobility and endogenous government decision making. For a model with scale econom ies in public good...

This paper derives a measure of the efficiency cost of taxing risky capital income in an infinite horizon stochastic model. The resulting expression differs from all those proposed in the existing literature. The correct measure of efficiency cost will normally be smaller than any of those used...

It is often argued that the use of distortionary taxation lowers the optimal provision of public goods below its optimal level in a first-best economy, which contains no restrictions on lump-sum taxation. However, this issue is usually investigated using commodity-tax models that contain no...
