We study the design of randomized controlled experiments in environments where outcomes are significantly affected by unobserved effort decisions taken by the subjects (agents). While standard randomized controlled trials (RCTs) are internally consistent, the unobservability of effort provision...

This study examines the trade-offs between the moral hazard (caused by changes in job search effort and workplace mobility), and the COVID-19 cases and mortality growth rates effects of Income support programs (ISPs). To identify ISPs causal effect, I use the variation in the timing of their...

Risk mitigation is an essential aspect of risk management, but it has largely evaded attention by auto insurers that optimize selective risk-sharing and claim mitigation instead. We use novel sensor data to study drivers' risky phone use behavior and how behavior-based insurance contracts can...

In this paper, we construct a joint production model of health with two-sided asymmetric information and ask the question, "How should physicians be compensated?" We demonstrate theoretically that the preferred physician compensation scheme depends on the illness condition. Outcome-contingent...

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...

Free markets for health care in Africa do not function properly, in that patients exhibit willingness to pay for health care and yet practitioners are unable to sell their services. It is widely acknowledged that health markets everywhere are troubled with imperfect information. Therefore it is...

This paper provides empirical evidence on the role of public health insurance in mitigating adverse outcomes associated with health shocks. Exploiting the rollout of a universal health insurance program in rural China, I find that total household income and consumption are fully insured against...

One of the main purposes of recent healthcare reform (Patient Protection and Affordable Care Act - ACA) in the U.S. is to enable Americans to make more productive use of their time. We examine how the ACA's dependent care coverage mandate (DCM) affected young adults' time allocation. Based on...

Through changing the connection between insurance and employment, the Affordable Care Act (ACA) has affected people's incentives to obtain education. We employ a triple-difference strategy comparing counties with different levels of uninsurance pre-ACA and in states with different Medicaid...
