Disruptions of the patient-general practitioner (GP) relationship due to GP exits affect patient outcomes in various ways. The literature suggests that the loss of a trusted professional can have negative effects, but also points at the benefits of being examined by a new GP. We study the impact...

While physicians are crucial to patient outcomes, what determines physician behavior and decision making remains to be understood. In this paper, we study how physicians' family characteristics influence physicians' behavior and patient health outcomes. Using administrative data from Denmark and...

We compare physician incomes using tax data from the United States, Canada, Sweden, and the Netherlands. Physicians are concentrated in the top percentiles of the income distribution in all four countries, especially in the United States and certain specialties. Physician incomes are highest in...

Is government guiding the invisible hand at the top of the labor market? We use new administrative data to measure physicians’ earnings and estimate the influence of healthcare policies on these earnings, physicians’ labor supply, and allocation of talent. Combining the administrative...

Roughly a quarter of physicians in the United States are either international medical graduates (IMGs) or foreign-born physicians (FBPs). We propose a theoretical model where patient preferences that disfavor IMGs and FBPs may result in those physicians offering better access to their services...

We use the medical specialties of physician-patients with advanced cancer to study the role of knowledge versus networks in treatment choices and patient survival by matching comparable patients with doctors and admission periods to control unobserved doctor quality. Physician-patients are less...

Most nations in the world have side-by-side private and public health care systems. Policymakers worry that "dual practice" across sectors might reduce care to the public sector. This concern led regions in Spain to offer "exclusivity bonuses" to physicians who practice exclusively in the public...

We examine the response of physicians to a series of changes in their national fee schedule designed to support the provision of higher quality healthcare. We evaluate the impact of these changes on total medical expenditures, the volume of services, and fees charged in a setting where doctors...

I investigate how office-based physicians respond to Medicare reimbursement changes. Using variation from an Affordable Care Act policy that increased reimbursements in four states, I run a difference-in-difference analysis comparing physicians with higher reimbursement increases to those with...

While there is a large literature investigating the response of treatment intensity to Medicare reimbursement differentials, there is much less work on this question for the Medicaid program. The answers for Medicare may not apply in the Medicaid context, since a smaller share of physician's...

We study how patient-regarding altruism is formed by medical education, a so far under-researched question. We structurally estimate altruistic preferences using experimental data from a large sample of medical students (N=733) in Germany at different stages in their studies. The estimates...

We draw upon newly merged administrative data sets to study the relationship between payments from medical technology firms to physicians and medical device procurement by hospitals. These payments (and the interactions that accompany them) may facilitate the transfer of valuable information to...

The role of artificial intelligence (AI) in augmenting healthcare is expected to grow substantially in future decades. Current research in medical AI focuses on developing, validating, and implementing point-level AI applications in an ad-hoc manner. To harness the full power of AI to improve...

This study contributes to the current understanding of what drives physicians to practice in rural areas by analyzing new, comprehensive survey data of practicing physicians in the United States. This research confirmed that rural origin is an important and reliable predictor for rural practice...

Who bears the consequences of administrative problems in healthcare? We use data on repeated interactions between a large sample of U.S. physicians and many different insurers to document the complexity of healthcare billing, and estimate its economic costs for doctors and consequences for...

Using cancer registry and doctor certificate records, we address unobserved physician quality issues by matching comparable patients with advanced cancer by doctor, hospital, and admission period. Estimates show that physician-patients are less likely to use surgery or radiation, more likely to...

We examine whether user-generated physician ratings from online sources signal physician quality information and affect patients' physician choices. We collect physician rating and review data from Yelp, a leading online physician rating platform, and match the rating data with Medicare claims...

We investigate the hypothesis that increasing access for the indigent to physician offices shifts care from hospital outpatient settings and lowers Medicaid costs (the so-called offset effect'). To evaluate this hypothesis we exploit a large increase in physician fees in the Tennessee Medicaid...

Recent efforts to increase price transparency for American consumers of health care have largely failed to produce savings. At the same time, little effort has been made towards increasing physician-side price transparency, which may be due to limited high-quality research being available on the...

Human antibiotic consumption is considered the main driver of antibiotic resistance. Reducing human antibiotic consumption without compromising health care quality poses one of the most important global health policy challenges. A crucial condition for designing effective policies is to identify...

We model the sorting of medical students across medical occupations and identify a mechanism that explains the possibility of differential productivity across occupations. The model combines moral hazard and matching of physicians and occupations with pre-matching investments. In equilibrium...
