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...

In a recent article, I demonstrated that, under standard simplifying assumptions, it is possible to finance a public good in a manner such that a Pareto improvement results whenever the simple cost-benefit test is satisfied -- that is, without any adjustment for the "marginal cost of funds." In...

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...

As a response to a changing labour market scenario and to the concerns for increasing costs and bad incentives of traditional income support policies, the last decades have witnessed, in many countries, reforms introducing more sophisticated designs of means-testing, eligibility and tagging. In...

We characterize optimal income taxation and unemployment insurance in a search-matching framework where both voluntary and involuntary unemployment are endogenous and Nash bargaining determines wages. Individuals differ in utility when voluntarily unemployed (non-participants in the labour...

Optimal policy rules - including those regarding income taxation, commodity taxation, public goods, and externalities - are typically derived in models with homogeneous preferences. This article reconsiders many central results for the case in which preferences for commodities, public goods, and...

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...

We study how an optimal income tax and an optimal public-goods provision rule respond to preference and productivity shocks. A conventional Mirrleesian treatment is shown to provoke manipulations of the policy mechanism by individuals with similar interests. We therefore extend the Mirrleesian...
