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....

We estimate the extensive and intensive margin labor supply response to the monthly Child Tax Credit disbursed in 2021 as a part of the American Rescue Plan Act. Using Current Population Survey microdata, we compare labor supply outcomes among households who qualify for varying relative...

Do high taxes cause superstars to work less? We test this hypothesis using complete data on Hollywood movie stars' labor supply from 1927 to 2014. Changes to marginal tax rates in high tax brackets have no significant effect on the number of films a movie star makes each year. However, in years...

The largest tax-based social welfare programs in the US limit their benefits to taxpayers with labor market income. Eliminating these work requirements would better target transfers to the neediest families but risks attenuating tax-based incentives to work. We study changes in labor force...

When is a wealth tax preferable to a capital income tax? When is the opposite true? More generally, can capital taxation be structured to improve productivity, incentivize innovation, and ultimately increase welfare? We study these questions theoretically in an infinite-horizon model with...

The philanthropic sector is highly consequential, particularly in the United States, and the most important policies directed toward this sector are tax policies. Yet most economic analysis of the optimal tax treatment of charitable giving is ad hoc, treating it as a subject unto itself. This...

This paper rethinks the design of the income tax by assuming that the objective of the tax is not to redistribute from rich to poor but instead to provide some insurance to individuals against the uncertainties they face in their future earnings, a motivation for the tax proposed in Buchanan...

Families provide substantial care to older adults with functional limitations. Policies that incentivize work have the potential to reduce this valuable care. This study uses the Health and Retirement Study (HRS) and a simulated instrument approach to examine the consequences of increases in the...

We examine union-non-union differentials in wages and hours in the United States over the last 50 years using data from the Current Population Survey (CPS). The regression-adjusted difference between union members' and non-members' hourly earnings has been falling since the Great Recession. The...

This paper explores how historical gender roles become entrenched as norms over the long run. In the historical United States, gender roles on the frontier looked starkly different from those in settled areas. Male-biased sex ratios led to higher marriage rates for women and lower for men. Land...
