Moral hazard and provider-induced demand may contribute to overutilization of scarce health care resources. The U.S. health care system includes several compensatory cost-containment mechanisms, but their effects depend on how patients and providers respond. We investigate hospice programs'...

Artificial intelligence (AI) is transforming production across all sectors of the economy, with the potential to both complement and substitute for traditional labor inputs. Healthcare is no exception. Dozens of recent academic studies demonstrate that AI can contribute to the healthcare value...

This paper examines whether loss of locally available hospital-based obstetric services affects racial/ethnic disparities in intrapartum care access and birth outcomes in rural areas of the US. To conduct causal inference, we combine difference-in-difference and propensity score matching methods...

The pharmaceutical market has experienced a massive wave of vertical integration between pharmacy benefit managers (PBMs) and health insurers in recent years. Using a unique dataset on insurer-PBM contracts, we document increasing vertical integration in Medicare Part D-vertically integrated...

We study the role of physicians in driving geographic variation of US healthcare utilization. We estimate a model that separates variation in average utilization of Medicare beneficiaries due to physicians, non-physician supply side factors, and patient demand. The model is identified by...

Technological innovation in medical services can improve health, but its ability to reach patients often depends on price signals for downstream providers, which can also be discordant across production inputs. We examine such a context when Medicare sharply revises facility fees--while holding...

Privatization has been shown to increase growth and profitability of public firms. However, effects on consumers are understudied. We study potential trade-offs in the US hospital sector where public control declined by 42% over 1983-2019. Private operators may improve hospitals' financial...

For those who follow health and technology news, it is difficult to go more than a few days without reading about a compelling new application of Artificial Intelligence (AI) to health care. AI has myriad applications in medicine and its adjacent industries, with AI-driven tools already in use...

Incomplete health insurance enrollment is a persistent U.S. challenge despite large subsidies. We ask whether hassles built into enrollment systems matter for insurance take-up and targeting. Studying removal of an auto-enrollment policy, we find that a small hassle - a requirement to actively...

Medicare has increased the use of performance pay incentives for hospitals, with the goal of increasing care coordination across providers, reducing market frictions, and ultimately to improve quality of care. This paper provides new empirical evidence by using novel operations and claims data...
