Advocates for "personalized medicine" tests claim they can reduce health care spending by identifying patients unlikely to benefit from costly treatments. But most tests are imperfect, and so physicians have considerable discretion in how they use the results. We show that when physicians face...

Physician treatment choices for observably similar patients vary dramatically across regions. This paper exploits cardiologist migration to disentangle the role of physician- specific factors such as preferences and learned behavior versus environment-level factors such as hospital capacity and...

Physicians, acting in their role as experts, are often faced with situations where they must trade off personal and patient welfare. Physicians' incentives vary based on the organizational environment in which they practice. We use the publication of a major clinical trial, which found that a...

Despite the fundamental role of deterrence in justifying a system of medical malpractice law, surprisingly little evidence has been put forth to date bearing on the relationship between medical liability forces on the one hand and medical errors and health care quality on the other. In this...

Spending on prescription drugs (Rx) represents one of the fastest growing components of U.S. healthcare spending, and has coincided with an expansion of pharmaceutical promotional spending. Most (83%) of Rx promotion is directed at physicians in the form of visits by pharmaceutical...

There is considerable controversy about the causes of regional variations in health care expenditures. Using vignettes from patient and physician surveys linked to fee-for-service Medicare expenditures, this study asks whether patient demand-side factors or physician supply-side factors explain...

In this paper, we use individual level data on purchases of one of the most prescribed categories of drugs (cholesterol-lowering statins) to study the responses of physicians and patients to variation in the cost of drugs. In a sample of first-time statin prescriptions to employees from a group...

Population growth, an unfinished agenda of communicable diseases and maternal health and nutrition, and the rapid rise of Non-communicable diseases are putting increasing strain on not just the Ministry of Health budget, but also the broader financial position of the government as a whole. These...

Samoa currently faces two important public policy challenges in the health sector. One is to stem, and then reverse, the rapid rise of non-communicable diseases (NCDs). The second challenge is to put the country on a health-financing path that is effective, efficient, and financially affordable...
