We introduce dynamic incentive contracts into a model of unemployment dynamics and present three results. First, wage cyclicality from incentives does not dampen unemployment dynamics: the response of unemployment to shocks is first-order equivalent in an economy with flexible incentive pay and...

We exploit policy discontinuities in Poland's unemployment insurance to examine the causal effect of changes to both benefit durations and levels. Using a regression discontinuity approach, we uncover three findings: (1) Higher benefit levels distort employment more than benefit extensions. (2)...

A long-standing economic question is how protection against harm from insurance or other harm reducing interventions leads to potentially offsetting behavior changes (ex-ante moral hazard). Immunization is a type of insurance, as individuals incur an upfront cost when they get vaccinated, but it...

The U.S. healthcare system requires substantial out-of-pocket payments by most consumers, which can prevent some from receiving needed medical services. Recent policy proposals seek to address this problem by increasing government health care spending in order to reduce out-of-pocket costs. The...

Patients rely on medical care providers to act in their best interests because providers understand disease pathology and appropriate treatment much better than patients. Providers, however, not only give advice (diagnose) but also deliver (sell) treatments based on that advice. This creates a...

Spending induced by health insurance is often called moral hazard and definitionally assumed to be inefficient. We adapt standard models and show that for those living "hand-to-mouth", the financing benefits of insurance cause a portion of moral hazard to be efficient. Although insurance's price...

Using data on prescriptions for cholesterol-lowering drugs (statins), we study differences in the treatments chosen by Danish physicians for themselves versus for their patients. We estimate that physicians discount patient health benefit relative to their own, valuing the additional potency of...

With the goal of lowering incentives for alcohol and substance abuse, U.S. states have historically permitted private health insurers to deny reimbursement of medical claims stemming from alcohol or opioid impairment. However, a potential unintended consequence of such "exclusion provisions" is...
