High administrative costs in U.S. health care have provoked concern among policymakers over potential waste, but many of these costs are generated by managed care policies that trade off bureaucratic costs against reductions in moral hazard. We study this trade-off for prior authorization...

In this paper, we test whether the Affordable Care Act Medicaid expansions are associated with in-hospital maternal morbidity. The ACA expansions may have affected maternal morbidity by increasing pre-conception access to health care, and by improving the quality of delivery care through...

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...

We study habit formation in annual biometric health screenings using a field experiment that randomly assigned financial incentives to 4,799 employees over three years. Completing the first screening raised subsequent screenings by 32.4-36.0 percentage points (84%-90%) annually. Habit formation...

We show that sugar-rich diet early in life has large adverse effects on the health and economic well-being of adults more than fifty years later. Excessive sugar intake early in life led to higher prevalence of chronic inflammation, diabetes, elevated cholesterol and arthritis. It also decreased...

We study the causes of "nutritional inequality": why the wealthy tend to eat more healthfully than the poor in the U.S. Using event study designs exploiting supermarket entry and households' moves to healthier neighborhoods, we reject that neighborhood environments have meaningful effects on...

We characterize optimal policies in a multidimensional nonlinear taxation model with bunching. We develop an empirically relevant model with cognitive and manual skills, firm heterogeneity, and labor market sorting. The analysis of optimal policy is based on two main results. We first derive an...

This paper outlines the case for using the Marginal Value of Public Funds (MVPF) in empirical welfare analysis. It compares the MVPF approach with more traditional welfare metrics such as the Cost-Benefit Ratio and the Net Social Benefits criterion. It outlines the advantages of the MVPF...
