Using novel data describing the healthfulness of household food purchases and the retail landscapes consumers face, we measure the role of access in explaining why wealthier and more educated households purchase healthier foods. We find that spatial differences in access, though significant, are...

This paper shows that the products and prices offered in markets are correlated with local income-specific tastes. To quantify the welfare impact of this variation, I calculate local price indexes micro-founded by a model of non-homothetic demand over thousands of grocery products. These indexes...

We examine how the amount a physician is paid influences who they are willing to see. Exploiting large, exogenous changes in Medicaid reimbursement rates, we find that increasing payments for new patient office visits reduces reports of providers turning away beneficiaries: closing the gap in...

While over 240,000 American students experienced a school shooting in the last two decades, little is known about the impacts of these events on the mental health of surviving youth. Using large-scale prescription data from 2006 to 2015, we examine the effects of 44 school shootings on youth...

A growing number of American children are exposed to gun violence at their schools, but little is known about the impacts of this exposure on their human capital attainment and economic well-being. This paper studies the causal effects of exposure to shootings at schools on children's...

This paper uses quarterly county-level data to examine the relationship between opioid prescription rates and employment-to-population ratios from 2006-2014. We first estimate models of the effect of opioid prescription rates on employment-to-population ratios, instrumenting opioid prescriptions...

Using national data on opioid prescriptions written by physicians from 2006 to 2014, we uncover a striking relationship between opioid prescribing and medical school rank. Even within the same specialty and practice location, physicians who completed their initial training at top medical schools...

The retail clinic is an innovation that has the potential to improve competition in health care markets. Given concern about inefficient use of the emergency room (ER) increasing health care costs, we use all ER visits in New Jersey from 2006-2014 to examine the impact of retail clinics on ER...

We ask how competition influences the prescribing practices of physicians. Law changes granting nurse practitioners (NPs) the ability to prescribe controlled substances without physician collaboration or oversight generate exogenous variation in competition. In response, we find that general...

We examine how health insurance expansions affect the entry and location decisions of health care clinics. Exploiting county-level changes in insurance coverage following the Affordable Care Act and 1,721 retail clinic entries and exits, we find that local increases in insurance coverage do not...
