When is a wealth tax preferable to a capital income tax? When is the opposite true? More generally, can capital taxation be structured to improve productivity, incentivize innovation, and ultimately increase welfare? We study these questions theoretically in an infinite-horizon model with...

This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....

Products with negative externalities are often subject to regulations that limit competition. The single-product case may suggest that it is irrelevant for aggregate welfare whether output is restricted via corrective taxes or limiting competition. However, when products are differentiated...

Numerous recent studies have indicated that interactions with a tax-distorted labor market increase the cost of pollution regulation. However, these studies have made restrictive assumptions regarding individual preferences and have ignored key links between pollution, human health, and labor...

The literature on environmental taxation in the presence of pre-existing distortionary taxes has shown that the interactions with pre-existing taxes tend to raise the cost of an environmental tax, and thus that the optimal environmental tax in that context is less than marginal environmental...

The strength of the behavioral response to a tax rate change depends on the environment individuals operate in, and may be manipulated by instruments controlled by the government. We first derive a measure of the social benefit to affecting this elasticity. The paper then examines this effect in...

There has been keen interest in recent years in environmentally motivated or 'green' tax reforms. This paper employs analytical and numerical general equilibrium models to investigate the costs of such reforms, concentrating on the question of whether these costs can be eliminated when revenues...
