This paper examines the tradeoffs of monitoring for wasteful public spending. By penalizing unnecessary spending, monitoring improves the quality of public expenditure and incentivizes firms to invest in compliance technology. I study a large Medicare program that monitored for unnecessary...

There is substantial evidence that cost-sharing in medical care constrains total health spending. However, there is relatively little (and unclear) evidence on its health effects, particularly in low- and middle-income countries. This paper re-evaluates the link between outpatient cost-sharing...

We evaluate the introduction of direct-acting antiviral (DAA) therapy for Hepatitis C (HCV) on liver transplant allocation in the United States. We develop a model of listing and organ acceptance behavior for patients with both HCV-positive and HCV-negative end-stage liver disease. In the model,...

We measure whether expert patients - those trained as physicians and nurses - have fewer emergency department visits and the reasons for these differences. Relative to similar patients physicians and nurses had 19.8% and 5.1% fewer ED visits, principally due to fewer avoidable visits. The...

We examine whether loss of emergency department services is associated with county-level mortality rates in rural areas over the period 2005-2018. We use a propensity-weighted difference-in-difference approach, comparing counties that lost emergency department services to counties that retained...

This study examines "tunneling" practices through which health care providers covertly extract profit by making inflated payments for goods and services to commonly-owned related parties. While incentives to tunnel exist across sectors, health care providers may find it uniquely advantageous to...

This paper investigates the importance of the age composition for pandemic policy design. To do so, it introduces an economic framework with age heterogeneity, individual choice, and incomplete information, emphasizing the value of testing. Calibrating the model to the US Covid-19 pandemic...

We study disparities in liver transplant allocation when innovation alleviates the scarcity of organs. When direct-acting antivirals for Hepatitis C (HCV) reduced HCV+ liver demand, we show a disproportionate increase in White HCV- liver transplants (56.6%) relative to Black HCV- transplants...
