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...

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...

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...

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 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...

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...

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...

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...

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...

The 'induced demand' model states that in the face of negative income shocks physicians may exploit their agency relationship with patients by providing excessive care in order to maintain their incomes. We test this model by exploiting an exogenous change in the financial environment facing...

While efforts to improve the health of the uninsured have focused on demand side policies such as increasing insurance coverage, supply side changes may be equally important. Yet there is little direct evidence on the effect of policies designed to increase the supply of Medicaid services to the...

The 2019 MacKinnon report, commissioned by the Alberta government, recommended ending fee-for-service (FFS) as the model for paying primary care physicians because of its significant and inherent inefficiencies. Since then, the COVID-19 pandemic has also demonstrated the value of moving...

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...

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...

We analyse how physicians respond to contractual changes and incentives within a multitasking environment. In 1999 the Quebec government (Canada) introduced an optional mixed compensation system, combining a fixed per diem with a discounted (relative to the traditional fee-for-service system)...

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...

Reducing human antibiotic consumption without compromising health care quality poses one of the most important global health policy challenges.

The objective of this study is to use data from the National Survey of Children with Special Health Care Needs (NS-CSHCN) to test whether Medicaid physician fees are correlated with access to health services and adequacy of insurance coverage among CSHCN. We use a difference-in-differences...

Hospital and health care administrators have often named prescription drug costs as one of their largest cost problems. Relatedly, a significant body of research demonstrates that meals and honoraria from pharmaceutical firms to physicians leads to higher prescribing of expensive, brand name...
