Policymakers are increasingly interested in non-standard policy instruments (NPIs), or "nudges," such as simplified information disclosure and warning labels. We characterize the welfare effects of NPIs using public finance sufficient statistic approaches, allowing for endogenous prices, market...

When individuals’ utility is a convex combination of their income and their concern at having a low relative income (the weights attached to income and to the concern at having a low relative income sum up to one), the maximization of aggregate utility yields an equal income distribution. This...

We consider the optimal policy problem of a benevolent planner, who is uncertain about an individual's true preferences because of inconsistencies in revealed preferences across behavioral frames. We adapt theories of expected utility maximization and ambiguity aversion to characterize the...

Economists have long studied policy choice by a social planner who aims to maximize welfare in democracies or other political systems where, in some sense, welfare is intended to express the well-being of a society rather than the personal preferences of a dictator. The motivation for studying...

Argenziano and Gilboa (2019) obtain a very important result ‘that consumer choice data alone are sufficient … [to] provide a microfoundation for a weighted utilitarian social welfare function that reflects common moral intuitions about interpersonal comparisons of utilities’. This paper...

This paper analyzes optimal pre-announced capital and labor income tax reforms under valuable and productive government spending. Our baseline optimal reform reveals that these model ingredients result in a reduction of welfare losses that occur when the reform is announced before its...

Researchers cannot definitively interpret what the framers of the United States Constitution had in mind when they wrote of the general Welfare. Nevertheless, welfare economics can contribute to policy choice in democracies. Specifying social welfare functions enables coherent analysis, by...

When individuals' utility is a convex combination of their income and their concern at having a low relative income (the weights attached to income and to the concern at having a low relative income sum up to one), the maximization of aggregate utility yields an equal income distribution. This...
