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...

The conventional view of economists is that the optimal supply of public goods must directly take into account the cost of financing them with distortionary taxes, notably the income tax. However, this article demonstrates, under standard simplifying assumptions, that it is possible to finance a...

We consider the problem of repeatedly choosing policies to maximize social welfare. Welfare is a weighted sum of private utility and public revenue. Earlier outcomes inform later policies. Utility is not observed, but indirectly inferred. Response functions are learned through experimentation....

This paper analyzes optimal social discount rates where people derive utility from relative consumption. We identify and compare three separate discount rates: the social rate (taking positional externalities into account), the private rate, and the conventional Ramsey rate. Two main findings...

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...

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 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....

In this note we discuss how to treat taxes in a cost-benefit analysis (CBA). In particular we relate the shadow price of taxes in CBA to the concepts the marginal cost of public funds MCPF) and the marginal excess burden (MEB) of taxes. In particular we demonstrate that the MCPF is equal to one...

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...
