This paper studies the causal mechanisms behind persistent poverty. Using original data on Boran pastoralists of southern Ethiopia, we find that heterogeneous and nonlinear wealth dynamics arise purely in adverse states of nature. In favorable states, expected herd grow is quasi-linear and...

Despite its promise to help low-wealth households manage climate risk, index insurance remains hampered by downside basis risk, meaning that an insured party suffers a loss, but receives no payment because the insurance index fails to register a loss. While efforts to reduce basis risk focus on...

Functional disability (difficulty in walking , difficulty in bending, paralysis, blindness in at least one eye, and deafness in at least one ear) in the United States has fallen at an average annual rate of 0.6 percent among men age 50 to 74 from the early twentieth century to the early 1990s....

Lead poisoning has well-known impacts for the developing brain of young children, with a large literature documenting the negative effects of elevated blood lead levels on academic and behavioral outcomes. In April of 2014, the municipal water source in Flint, Michigan was changed, causing lead...

We study whether vouchers with and without value information encourage completion of already free follow-up appointments in a low-income minority population in Baltimore City referred for possible eye disease. Between May 2017 and September 2018, 821 individuals referred for free follow-up from...

We examine the effects of must-access prescription drug monitoring programs (PDMPs) and recent regulations limiting the duration of initial opioid prescriptions on care received by patients with work-related injuries, focusing on opioid utilization and medical care related to pain management. We...

This paper studies how U.S. employees use paid sick leave. The most common U.S. sick-leave schemes operate as individualized credit accounts---paid leave is earned over time and unused leave accumulates, producing an employee-specific "leave balance." We construct a unique administrative dataset...

While the COVID-19 pandemic has laid bare the large costs of infectious diseases, less attention has been paid to the impacts of more common, endemic respiratory viruses that frequently circulate in the population, especially when it comes to their potential long-term consequences for population...

It is well established that the social and economic environment of medical care distinguishes its provision from that of other goods and services. While scholars have studied the influences of this idiosyncratic environment, there is relatively little empirical knowledge about how it affects...

Urgent care centers (UCCs) are a cost-efficient substitute to the emergency department (ED) for non-emergent conditions, but no study has identified their impact on ED demand. We address this gap using a novel strategy that exploits daily UCC operating times in a differencing framework. After...
