Specialized theoretical and empirical research should in principle be embedded in a unified framework that identifies the relevant interactions among different phenomena, enables an appropriate matching of policy instruments to objectives, and grounds normative analysis in individuals' utilities...

This Handbook entry presents a conceptual, normative overview of the subject of taxation. It emphasizes the relationships among the main functions of taxation—notably, raising revenue, redistributing income, and correcting externalities—and the mapping between these functions and various...

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....

The literature on optimal redistributional instruments begins with the assumption that society has some preference for equality, leaving the precise degree unspecified. It then asks: How should society pursue that preference? More specifically, what kinds of policy instruments — whether...

There should be no debate about whether taxes on food, alcohol, tobacco and soft drinks (‘sin taxes’) are regressive. It can be easily demonstrated empirically, and countless studies have done so. As with most indirect taxes, they take a greater share of income from the poor than from the...

This study calculates efficient taxes on gasoline and road use designed to combat driving related externalities when motorists avoid taxes due to an excessive economic driving-style. The efficient tax on gasoline is reduced below the Pigouvian rate due to such avoidance. The current US tax rate...

A tax on fuel combined with tax-exemptions or subsidies for purchase of fuel-efficient vehicles is implemented in many countries to reduce greenhouse gas emissions and other negative externalities from road traffic. This study, however, shows that a tax on fuel should be combined with heavier...

There currently exist two competing approaches in the literature on the optimal provision of public goods. The standard approach highlights the importance of distortionary taxation and distributional concerns. The new approach neutralizes distributional concerns by adjusting the non-linear...

This paper deals with the consequences of the assumption of negatively interdependent preferences for the shape of the optimal nonlinear income tax and the effcient level of public good provision in a setting where the policy maker maximizes an inequality averse social welfare function and the...
