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...

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...

A substantial literature examines second-best environmental policy, focusing particularly on how the Pigouvian directive that marginal taxes should equal marginal external harms needs to be modified in light of the preexisting distortion due to labor income taxation. Additional literature is...

Various economic literatures address the question whether first-best prescriptions for government policy require modification because redistributive income taxation distorts labor supply and cannot achieve the distributive ideal. Perhaps second-best rules for public goods provision, corrective...

Should the assessment of government policies, such as the provision of public goods and the control of externalities, deviate from first-best principles to account for distributive effects and for the distortionary cost of labor income taxation? For example, is the optimal extent of public goods...

The traditional view of economists has been that corrective taxes are superior to direct regulation of harmful externalities when the state's information about control costs is incomplete. In recent years, however, many economists seem to have adopted the view that either corrective taxes or...

We examine how moral sanctions and rewards, notably the moral sentiments involving feelings of guilt and virtue, would be employed to govern individuals' behavior if the objective were to maximize social welfare. In our model, we analyze how the optimal use of guilt and virtue is influenced by...

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 prohibition against price fixing is competition law’s most important and least controversial provision. Yet there is far less consensus than meets the eye on what constitutes price fixing, and prevalent understandings cannot be reconciled with principles of oligopoly theory. This article...

This article examines optimal policy toward coordinated oligopolistic price elevation. First, it analyzes the social welfare implications of enforcement, elaborating the value of deterrence and the nature of possible chilling effects. Then, it explores a variety of means of detection, with...
