We study the impact of social health insurance on mortality. Using the introduction of compulsory health insurance in the German Empire in 1884 as a natural experiment, we estimate flexible difference-in-differences models exploiting variation in eligibility for insurance across occupations. Our...

A vast literature studies the behavioural impacts of health care reforms, often coming to controversial conclusions. Here we examine the time allocation effects of the Affordable Care Act, also known as Obama Care, focusing on two ACA pillars: Medicaid expansion, which increased access to public...

We provide new insights regarding the finding that Medicaid increased emergency department (ED) use from the Oregon experiment. We find meaningful heterogeneous impacts of Medicaid on ED use using causal machine learning methods. The treatment effect distribution is widely dispersed, and the...

We report on a large randomized controlled trial of hospital insurance for above-poverty-line Indian households. Households were assigned to free insurance, sale of insurance, sale plus cash transfer, or control. To estimate spillovers, the fraction of households offered insurance varied across...

We examine the early effects of U.S. state Medicaid expansions under the Affordable Care Act (ACA) on substance use disorder (SUD) treatment utilization. We couple administrative data on admissions to specialty SUD treatment and prescriptions for medications used to treat SUDs in outpatient...

States with Section 1332 Waivers to operate high-risk pools (HRPs) or reinsurance programs can receive federal pass through funds equal to reductions in federal expenditures generated by the Waiver. Shifting financial responsibility for high-cost individuals out of the Health Insurance Exchange...

This paper examines the impacts of the Affordable Care Act (ACA) – which substantially increased insurance coverage through regulations, mandates, subsidies, and Medicaid expansions – on behaviors related to future health risks after three years. Using data from the Behavioral Risk Factor...

Starting from December 2012, insurers in the European Union were prohibited from charging gender-discriminatory prices. We examine the effect of this unisex mandate on risk segmentation in the German health insurance market. While gender used to be a pricing factor in Germany's private health...

In 2007, China launched a subsidized voluntary public health insurance program, the Urban Resident Basic Medical Insurance, for urban residents without formal employment, including children, the elderly, and other unemployed urban residents. We estimate the impact of this program on health care...

Employer-provided health insurance may restrict job mobility, resulting in "job lock." Previous research on job lock finds mixed results using several methodologies. We take a new approach to examine job-lock by exploiting the discontinuity created at age 65 through the qualification for...
