This paper investigates the impact of the Affordable Care Act’s (ACA’s) dependent coverage mandate on health insurance coverage rates and health care utilization among young adults. Using data from the Medical Panel Expenditure Survey, I exploit the discontinuity in health insurance coverage...

The first major insurance expansion of the Affordable Care Act – a provision requiring insurers to allow dependents to remain on parents’ health insurance until turning 26 – took effect in September 2010. We estimate this mandate’s impacts on numerous health-related outcomes using a...
