To equalize differences in health plan premiums due to differences in risk pools, the German legislature introduced a simple Risk Adjustment Scheme (RAS) based on age, gender and disability status in 1994. In addition, effective 1996, consumers gained the freedom to choose among hundreds of...

Over the last two decades, state and local governments have adopted policies requiring employers to electronically verify (E-Verify) the work eligibility of their new hires, in an effort to disrupt unauthorized immigrants' access to the formal labor market. These EVerify mandates previously...

We introduce new risk groups to a standard capitation formula and evaluate risk selection incentives of insurers. The study uses a unique data set of almost 24 million affiliates to Government's mandatory health insurance system. This data set is very rich in the sense of reporting all claims...

Many governments with dual public and private health systems subsidise private health insurance (PHI) with the aim to ease the burden on the public system. Understanding how elderly individuals respond to subsidies is important because they can benefit more from PHI but often find it...

Many have argued that concerns over health insurance reduce labor market mobility in the United States, causing a “job lock” effect. We take advantage of the novel natural experiment created by the Affordable Care Act's dependent coverage mandate to estimate the magnitude of the job lock...

Incomplete health insurance enrollment is a persistent U.S. challenge despite large subsidies. We ask whether hassles built into enrollment systems matter for insurance take-up and targeting. Studying removal of an auto-enrollment policy, we find that a small hassle - a requirement to actively...

Penalty mandates are used in many countries to encourage people to purchase health insurance. But are they effective? We use a large administrative dataset for a 10% random sample of all Australian tax-filers to study how people respond to a step-wise age-based mandate, and whether this has...

In theory, guaranteed renewable (GR) insurance contracts can efficiently protect individuals against reclassification risk without the negative side effects of price regulation, such as adverse selection. For these contracts to work properly, consumers must pay front-loaded premiums when healthy...

The Australian government pays $6.5 billion per year in rebates to encourage Australians to purchase private health insurance (PHI) and an additional $3 billion to cover private inpatient medical services. What is the justification for large government subsidies to a private industry when all...
