Obtaining better information on the quality of health care providers is one of the most pressing issues in health policy today. In this paper we (1) develop a new method for measuring quality of care that overcomes the key limitations of available quality measures, and (2) apply this method to...

This paper uses data from 802,777 veterans assigned to 7,548 primary care providers (PCPs) within the Veterans Health Administration (VHA) to examine variations in the efficacy of primary care providers (PCPs), their consequences for health outcomes, and their determinants. Leveraging...

We measure inequities from the COVID-19 pandemic on mortality and hospitalizations in the United States during the early months of the outbreak. We discuss challenges in measuring health outcomes and health inequality, some of which are specific to COVID-19 and others that complicate attribution...

Using administrative data on over 4 million hospital visits, we document striking gender disparities within a government health insurance program that entitles 46 million poor individuals to free hospital care in Rajasthan, India. Females account for only 33% of hospital visits among children...

Adoption of health information and communication technologies ("HICT") has surged over the past two decades. We survey the medical and economic literature on HICT adoption and its impact on clinical outcomes, productivity and labor. We find that HICT improves clinical outcomes and lowers...
