In theory, there are several reasons why physician organizational form might affect the price, quantity, and quality of physician services. In this paper, we examine the effect of three aspects of physician organizational form on opioid prescribing: the number of physicians in the physician's...

We examine whether medical innovation can reinforce existing health disparities by disproportionately benefiting socioeconomically advantaged patients. The reason is that less advantaged patients often do not use new medications. This may be due to high costs of new drugs, but could also reflect...

A booster of the COVID-19 vaccine targeting the prevailing Omicron variant did not become available in the United States until a year after the variant was first detected. This pattern of developing, testing, and distributing a variant-specific booster may become the default response to further...

Shortages and rationing are common in health care, yet we know little about the consequences. We examine an 18-month shortage of the pediatric Haemophilus Influenzae Type B (Hib) vaccine. Using insurance claims data and variation in shortage exposure across birth cohorts, we find that the...

We hypothesize that the impact of antibiotics is moderated by a population's inherent (genetic) resistance to infectious disease. Using the introduction of sulfa drugs in 1937, we show that US states that are more genetically susceptible to infectious disease saw larger declines in their...

Academic Medical Centers (AMCs)--comprising medical schools, teaching hospitals, and research laboratories)--play an important role in US biomedical innovation. The Balanced Budget Act of 1997 (BBA) changed the formula used to reimburse Medicare inpatient claims and subsidies for medical...

The entry of married women into the labor force is one of the most notable economic phenomena of the twentieth century. We argue that medical progress played a critical role in this process. Improved maternal health alleviated the adverse effects of pregnancy and childbirth on women's ability to...

Many opioid control policies target the prescribing behavior of health care providers. In this paper, we study the first comprehensive state-level policy requiring providers to access patients' opioid history before making prescribing decisions. We compare prescribers in Kentucky, which...

Overuse of medical care is often attributed to an informed expert problem, whereby doctors induce patients to purchase unnecessary treatments. Alternatively, patients may drive overuse of medications by exerting pressure on doctors to overprescribe, undermining the doctor's gatekeeping function...

Beginning around 1990, academic medical centers have ceased to be the primary locus of industry-sponsored clinical trial activity. Instead, clinical trials have increasingly been conducted in private practices and for-profit, dedicated study sites. We examine the underlying causes of this...
