Publications

"Falling Racial Inequality and Rising Educational Inequality in US Prison Admissions for Drug, Violent, and Property Crimes" (with Alexander F. Roehrkasse). Proceedings of the National Academy of Sciences 122, no. 4 (2025): e2418077122.

Exposes how violent offenses have replaced drug offenses as the primary driver of Black prison admissions and Black–White inequality in the prison admission rate. Demonstrates that the prison admission rate of Black Americans has fallen, but the prison admission rate of White Americans with no college education has dramatically increased for all offense categories.

"Racial and Class Inequality in US Incarceration in the Early Twenty-First Century" (with Alexander F. Roehrkasse). Social Forces 101, no. 2 (2022): 803-828.

Seeks to give the debate around the relative importance of racial and class inequality in incarceration in the United States a stronger empirical foundation.

"Exclusion and Exploitation: The Incarceration of Black Americans from Slavery to the Present" Science 374, no. 6565 (2021): 282-286.

Offers a parsimonious framework describing how the Black incarceration rate has been affected by the dynamics of exploitation and exclusion over time and across space.

"The Political Economy of Incarceration in the Cotton South, 1910–1925" (with Daniel Schrage). American Journal of Sociology 127, no. 3 (2021).

Estimates the effect of a shock to the southern agricultural labor market during a time when planters exerted a clear influence over whether workers or potential workers were incarcerated. Describes the institutional conditions under which falling labor demand should increase incarceration, clarifies the relationship between incarceration and the economic institutions that replaced slavery, and contributes to a growing literature on incarceration and exploitation in the labor market.

"Freedom and Convict Leasing in the Postbellum South" American Journal of Sociology 124, no. 2 (2018): 367-405.

Finds that black men were most likely to be imprisoned in the convict lease system where they overcame whites’ efforts to preserve their position as dependent agricultural laborers.

"Mass Imprisonment and Trust in the Law" (with Daniel Schrage). The ANNALS of the American Academy of Political and Social Science 651, no. 1 (2014): 139-158.

"Mass Imprisonment and Inequality in Health and Family Life" (with Christopher Wildeman). Annual Review of Law and Social Science 8 (2012): 11-30.
