We ask how patient knowledge of appropriate antibiotic usage affects both physicians prescribing behavior and the physician-patient relationship. We conduct an audit study in which a pair of simulated patients with identical flu-like complaints visits the same physician. Simulated patient A is...

Public technology assessments in general and Comparative Effectiveness Research (CER) in particular have been justified by offsetting benefits of improving patient health and reducing health care spending. However, little conceptual and empirical understanding exists concerning the quantitative...

We use unique data from an insurer that exclusively offers high-deductible, "consumer-directed" health plans to identify the effect of plan features, notably the spending account, on health care spending. Our results show that the marginal dollar in the spending account is entirely spent on...

It is often argued that cost-sharing -- charging a subsidized, positive price -- or a health product is necessary to avoid wasting resources on those who will not use or do not need the product. We explore this argument through a field experiment in Kenya, in which we randomized the price at...

Basic economic theory suggests that health insurance coverage may cause a reduction in prevention activities, but empirical studies have yet to provide much evidence to support this prediction. However, in other insurance contexts that involve adverse health events, evidence of ex ante moral...

We explore the effects of recent Medicaid expansions on Medicaid-financed prescriptions for evidence-based smoking cessation medications. We estimate differences-in-differences models using administrative data on the universe of prescription medications sold in retail and online pharmacies for...

Using unique individual-level panel data, we investigate whether preventive medical care triggered by health checkups is worth the cost. We exploit the fact that biomarkers just below and above a threshold may be viewed as random. We find that people respond to health signals and increase...

This paper exploits a sharp reduction in patient cost sharing at age 70 in Japan, using a regression discontinuity design to examine its effect on utilization, health, and financial risk arising from out-of-pocket expenditures. Due to the national policy, cost sharing is 60-80 percent lower at...

The national hepatitis C elimination initiative provides an opportunity to dramatically expand access to hepatitis C virus (HCV) treatment and put the US on a path to eliminating hepatitis C. Our objective was to project the health benefits and cost savings of this initiative. A previously...
