Due to COVID-19, 33 states banned elective medical procedures, and 13 of these states included surgical abortions. We collected street addresses of abortion clinics and linked them to SafeGraph’s data on counts of visitors. We found a 32 percent decrease in clinics visits in February-May of...

Medical divorce occurs when couples split up so that one spouse's medical bills do not deplete the assets of the healthy spouse. It has not been studied in the economics literature, but it has been discussed by attorneys and widely reported in the media. We develop a model of medical divorce...

Disability benefit recipients in the United States have nearly doubled in the past two decades, growing substantially faster than the population. It is difficult to estimate how much of this increase is explained by changes in population health, as we often lack a valid counterfactual. We...

Recent medical literature suggests that vitamin D supplementation protects against acute respiratory tract infection. Humans exposed to sunlight produce vitamin D directly. This paper investigates how differences in sunlight, as measured over several years across states and during the same...

One in twelve Americans suffers from asthma and its annual costs are estimated to exceed $50 billion. Simultaneously, the root causes of the disease remain unknown. A recent hypothesis speculates that maternal vitamin D levels during pregnancy affect the probability the fetus later develops...

This study quantifies the effect of state reopening policies on daily mobility, travel, and mixing behavior during the COVID-19 pandemic. We harness cell device signal data to examine the effects of the timing and pace of reopening plans in different states. We quantify the increase in mobility...

We study the effects of the temporary federal paid sick leave mandate that became effective April 1st, 2020 on ‘social distancing,' as proxied by individuals' physical mobility behavior gleaned from cellular devices. The national paid leave policy was implemented in response to the COVID-19...
