Policing Race and Place during a Pandemic: A Multi-City Study
I am Principal Investigator (co-PI Jaquelyn Jahn) of a project that examines policing during the COVID-19 pandemic and how disparities in enforcement may have widened across urban neighborhoods and cities. Using a novel dataset of police contact derived from publicly available reports in cities across the United States, we analyze the extent to which policing was used to enforce social distancing and in which census tracts and cities. We therefore study two social phenomena: (1) citizens reporting crime to police by calling 911, especially to report nuisances or disturbances, and (2) police arrests. Each of these describe different pathways that could drive disparity in police contact, and both are reported by cities at the longitude/latitude on a weekly or monthly basis. Thus, our research aims to address the following questions:
(1) Aim 1: Did police contact (i.e. arrests and 911 calls regarding disturbances, curfew violations, and gatherings) in metropolitan cities change during stay-home orders and the pandemic overall, relative to the year prior?
(2) Aim 2: What is the racial disparity in rates of police contact? Did these rates widen relative to those the year prior? Are these trends stronger in cities with larger police forces before the pandemic?
(3) Aim 3: Are rates and/or racial disparities in police contact higher in areas that had higher levels of household poverty or income inequality; higher proportions of Black, Latino, or Asian residents; are more segregated; or more residents with elevated risk of SARS-Cov-2 exposure?

Pennsylvania Solitary Study (PASS)
Solitary confinement is an extreme form of prison custody involving isolation from the prison’s general population and highly restricted access to visitation and phone calls, programs, and free movement outside of a prison cell. I am co-Principal Investigator (PI: Bruce Western) of the Pennsylvania Solitary Study (PASS). PASS examines the effects and conditions of solitary confinement with a longitudinal survey of incarcerated men (N=117, including a main sample of 99 and a pretest sample of 18) who were living in a Restricted Housing Unit in the Pennsylvania state prison system during 2017. Combining fieldwork and interviews with incarcerated people and prison staff (N=22), a neurocognitive battery administered to incarcerated respondents, and an analysis of administrative records, PASS breaks new ground in research on prisons and inequality, using mixed methods to study conditions of prison confinement and effects on health and well-being, labor force participation after prison release, and recidivism. This project examines the demographic prevalence of solitary confinement. In one study, we find that 11 percent of Black men born in 1986-1989 will experience solitary confinement by age 32.

Does Health Policy Prevent Exposure to the Criminal Justice System?
Although research has demonstrated the expansive role of police and carceral institutions to respond a broad range of social problems and health emergencies, existing research has not explored the capacity for health policy to influence rates of arrest or incarceration in the population. To fill this gap, I examine with Jaquelyn Jahn the potential effect of Medicaid expansion under the Affordable Care Act (ACA) on arrests in 3,035 U.S. counties. We compare county-level arrests using FBI Uniform Crime Reporting (UCR) Program Data before and after Medicaid expansion in 2014–2016, relative to counties in non-expansion states. We use difference-in-differences (DID) models to estimate the change in arrests following Medicaid expansion for overall arrests, and arrests for violent, drug, and low-level offenses. Police arrests significantly declined following the expansion of Medicaid under the ACA. Medicaid expansion produced a 20-32% negative difference in overall arrests rates in the first three years. We observe the largest negative differences for drug arrests: we find a 25-41% negative difference in drug arrests in the three years following Medicaid expansion, compared to non-expansion counties. We observe a 19–29% negative difference in arrests for violence in the three years after Medicaid expansion, and a decrease in low-level arrests between 24–28% in expansion counties compared to non-expansion counties. Our main results for drug arrests are robust to multiple sensitivity analyses, including a state-level model.
