Does Diversity Matter for Health? Experimental Evidence from Oakland

American Economic Review (forthcoming) with Marcella Alsan and Owen Garrick


We study the effect of physician workforce diversity on the demand for preventive care among African-American men. In an experiment in Oakland, California, we randomize black men to black or non-black male medical doctors. We use a two-stage design, measuring decisions before (pre-consultation) and after (post-consultation) meeting their assigned doctor. Subjects select a similar number of preventives in the pre-consultation stage, but are much more likely to select every preventive service, particularly invasive services, once meeting with a racially concordant doctor. Our findings suggest black doctors could reduce the black-white male gap in cardiovascular mortality by 19%.

Workers’ Spending Response to the 2011 Payroll Tax Cuts

American Economic Journal: Economic Policy (2016) with Wilbur van der Klaauw and Basit Zafar


This paper investigates workers’ spending response to the 2011 payroll tax cuts. Respondents were surveyed at the beginning and end of 2011, which allows the comparison of ex ante and ex post reported use of the extra income. While workers on average intended to spend 14 percent of their tax cut income, they ex post reported spending 36 percent of the funds. This pattern of higher spending ex post is shared across all demographic groups. Differences across workers in this shift to greater ex post spending are largely unexplained by differences in either present bias or unanticipated shocks, so in the end the upward revision in spending remains a puzzle.

Works In Progress

The Impact of Physician Density: An Event Study Approach

Among the many barriers to accessing healthcare in the US, public discourse often refers to low physician density, especially in rural and low income urban areas. To address this, county and sub-county regions can apply to be designated as a Medically Underserved Area (MUA) and/or a Healthcare Professional Shortage Area (HPSA). These federally recognized designations allow for federal financial support to encourage physicians to practice in such areas. In this project, I use an event study approach to first estimate the causal impact of these federal policies on physician density and then estimate the impact of physician density on health and economic outcomes.

Estimating the Impact of Hospital Integration in the American South

Leveraging a new identification strategy, I estimate the impact of the legally mandated racial integration of American hospitals in 1964 on both agricultural productivity and poverty-related outcomes. I use a difference in differences design to estimate the causal impacts. As a control group, newly digitized documents from the National Archives identify southern counties that had racially integrated hospitals prior to the passage of the Civil Rights Act, which mandated that all hospitals provide integrated facilities.
