The Covid-19 pandemic is estimated to have caused over 7 million deaths and reduced economic output by over $13 trillion to date. While vaccines were developed and deployed with unprecedented speed, pre-pandemic investments could have accelerated their widespread introduction, saving millions of...

We examine the effect of enforcing minimum quality standards (MQSs) on consumer health. In the late 1800s, the urban milk supply was regularly skimmed and diluted with water, but consumers could not easily determine its quality because dyes, caramel, and salt were added. To protect consumers,...

The national hepatitis C elimination initiative provides an opportunity to dramatically expand access to hepatitis C virus (HCV) treatment and put the US on a path to eliminating hepatitis C. Our objective was to project the health benefits and cost savings of this initiative. A previously...

Many environmental hazards produce health effects that take years to arise, but quasi-experimental studies typically measure outcomes and treatment over short time periods. We develop a new approach to overcome this challenge and use it to gauge the effect of exposure to air pollution on US life...

We show that Covid-19 illnesses persistently reduce labor supply. Using an event study, we estimate that workers with week-long Covid-19 work absences are 7 percentage points less likely to be in the labor force one year later compared to otherwise-similar workers who do not miss a week of work...

The global COVID-19 vaccination campaign is the largest public health campaign in history, with over 2 billion people fully vaccinated within the first 8 months. Nevertheless, the impact of this campaign on all-cause mortality is not well understood. Leveraging the staggered rollout of vaccines,...

We attribute the recent quadrupling of heroin death rates to the August, 2010 reformulation of an oft-abused prescription opioid, OxyContin. The new abuse-deterrent formulation led many consumers to substitute to an inexpensive alternative, heroin. Using structural break techniques and variation...

The past century witnessed a dramatic improvement in public health, the rise of modern medicine, and the transformation of the hospital from a fringe institution to one essential to the practice of medicine. In this paper, we explore how access to the hospital and modern medicine affects...

The opioid crisis generates broader societal harms beyond direct health and economic effects, impacting non-users through adverse spillovers on children, families, and communities. We study the spillover effects of a supply-side policy aimed at reducing the over-prescribing of opioids on women's...

We estimate the effects of permanent legal status on the health of children born to immigrants in the United States using variation from the Immigration Reform and Control Act of 1986 (IRCA). Our empirical approach compares trends in birth outcomes for foreign-born Mexican mothers across...
