Some commentators estimate that up to a third of U.S. medical spending may be wasted. This study focuses on the decision to hospitalize elderly Medicare patients who present at the emergency room (ER) with respiratory conditions. Failing to hospitalize sick patients could have dire consequences....

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...

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...

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...

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...

Emergency department visits are costly to providers and to patients. We use the Flint water crisis to test if an increase in office visits reduced avoidable emergency room visits. In September 2015, the city of Flint issued a lead advisory to its residents, alerting them of increased lead levels...

Mergers that affiliate a hospital with a Catholic owner, network, or system reduce the set of possible reproductive medical procedures since Catholic hospitals have strict prohibitions on contraception. Using changes in ownership of hospitals, we find that Catholic hospitals reduce the per bed...

We are the first to examine the effect of Superfund cleanups on infant health rather than focusing on proximity to a site. We study singleton births to mothers residing within 5km of a Superfund site between 1989-2003 in five large states. Our "difference in differences" approach compares birth...

Recent research shows that health at birth is affected by many factors, including maternal education, behaviors, and participation in social programs. In turn, endowments at birth are predictive of adult outcomes, and of the outcomes of future generations. Exposure to environmental pollution is...
