We show that more human capital improves incentives in a standard optimal taxation problem: common assumptions about preferences and technology imply that the disutility of labor decreases less strongly in unobserved ability if agents have more human capital. Human capital thus reduces the...

We study optimal capital taxation in a dynamic Mirrleesian model with time-nonseparable preferences. The model covers the widely used cases of habit formation and durable consumption. Time-nonseparable preferences change labor supply incentives across time and thereby generate novel motives to...

Economic thought on climate policy as an instance of environmental regulation is strongly influenced by the principle of a uniform carbon price. Economists acknowledge that this principle breaks down in a second-best world with other distortions, such as taxes and market power in domestic and...

We study education and income tax policies in a model with endogenous selection into college. Our framework is strongly influenced by the empirical college literature and incorporates heterogenous returns and tastes for college, earnings risk (implying uncertain returns to college) and...

This paper studies optimal taxation in a general equilibrium macro model with endogenous entry. We compare the constant elasticity of substitution (CES) model to three alternative demand structures: oligopolistic competition in prices, oligopolistic competition in quantities, and translog...

Economic models of climate policy (or policies to combat other environmental problems) typically neglect psychological adaptation to changing life circumstances. People may adapt or become more sensitive, to different degrees, to a deteriorated environment. The present paper addresses these...

Several frictions restrict the government s ability to tax assets. First of all, it is very costly to monitor trades on international asset markets. Moreover, agents can resort to non-observable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too...

The paper studies optimal income taxation in a model with labor supply responses at the intensive and the extensive margin. It is shown that a utilitarian desire for redistribution does not pin down the sign of the optimal marginal tax rate: labor supply may be downward distorted, undistorted,...

This paper explores the implications of gender-based income taxation in a non-cooperative model of a couple's time allocation between market work and providing a household public good. We find that the optimal structure of differential taxation by gender is solely determined by spouses' relative...

Regional productivity differences are large and provide scope for productivity-enhancing inter-regional labor mobility. Using an optimal taxation framework that combines an intensive labor supply margin with an extensive, productivity- enhancing migration margin, we explore the implications of...
