The U.S. opioid crisis is now driven by fentanyl, a powerful synthetic opioid that currently accounts for 90% of all opioid deaths. Fentanyl is smuggled from abroad, with little evidence on how this happens. We show that a substantial amount of fentanyl smuggling occurs via legal trade flows,...

While state incarceration policies have received much attention in research on the causes of mass incarceration in the U.S., their roles in shaping population health and health disparities remain largely unknown. We examine the impacts of two signature state incarceration policies adopted during...

A longstanding and influential view in U.S. correctional policy is that "nothing works" when it comes to rehabilitating incarcerated individuals. We revisit this hypothesis by studying an innovative law-enforcement-led program launched in the county jail of Flint, Michigan: Inmate Growth...

Did anti-Asian violence rise after the onset of the COVID-19 pandemic? Efforts to answer this question are compromised by the inherent difficulty of measuring racially-motivated crimes as well as concerns that reporting of racially-motivated hate crimes may have changed due to their increased...

We combine full-count Census data (1850-1940) with Census/ACS samples (1950-2020) to provide the first nationally representative long-run series (1850-2020) of incarceration rates for immigrants and the US-born. As a group, immigrants had higher incarceration rates than US-born white men before...

The Medicare hospice program is intended to provide palliative care to terminal patients, but patients with long stays in hospice are highly profitable, motivating concerns about overuse among the Alzheimer's and Dementia (ADRD) population in the rapidly growing for-profit sector. We provide the...

The myriad uncertainties common to the process of adjudication--concerning evidence that opposing parties will present, legal issues that will become relevant, illness of witnesses, and the like--lead to two social problems. First, when unanticipated events occur, the information that parties...

In the U.S., occupational licensing is more prevalent in the public sector than in the private sector, but the influence of occupational regulation for public sector workers has not been analyzed in detail. Our study initially examines the probability of a licensed worker selecting into the...

The paper examines changes in wage and hour labor regulation between 1898 and 1938. Many see the 1905 Lochner Supreme Court decision striking down hours limits for men as the beginning of 30 years in which labor regulation was stymied by the doctrine of "freedom of contract." That issue played a...
