Does Canada's publicly funded, single payer health care system deliver better health outcomes and distribute health resources more equitably than the multi-payer heavily private U.S. system? We show that the efficacy of health care systems cannot be usefully evaluated by comparisons of infant...

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...

There are ongoing debates around the world over the value of private supplements to public health insurance systems. We investigate this issue in the context of one of the world's deadliest diseases, diabetes, and one of the countries with the worst diabetes problems in the world, Mexico. We...

The aim of this paper is to assess the impact of the Community Health Center (CHC) on health levels in the U.S. Using infant mortality as the underlying health indicator, a time series of large counties as the data set, and multivariate regression techniques, we investigate the extent to which...

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...

Unlike in the production of most goods, changes in capacity for labor-intensive services only affect outcomes of interest insofar as service providers change the way they allocate their time in response to those capacity changes. In this paper, we examine how public sector service providers...

Improvements in medical treatment have contributed to rising health spending. Yet there is relatively little evidence on whether the spending increase is "worth it" in the sense of producing better health outcomes of commensurate value--a critical question for understanding productivity in the...

The Patient Protection and Affordable Care Act (ACA) increased demand for healthcare across the U.S., but it is unclear if or how the supply side has responded to meet this demand. In this paper, we take advantage of plausibly exogenous geographical heterogeneity in the ACA to examine the...

We use machine learning to better characterize low-value health care and the decisions that produce it. We focus on costly tests, specifically for heart attack (acute coronary syndromes). A test is only useful if it yields new information, so efficient testing is grounded in accurate prediction...

Evidence of regional variation in health care utilization has been well-documented over the past 40 years. Yet uncertainty persists about whether this variation is primarily the result of supply-side or demand-side forces, and the difference matters for both theory and policy. In this article,...
