The Affordable Care Act (ACA), enacted in 2010, was intended to address long- standing problems with the American system of health care and health insurance. This column, taken from a new VoxEU eBook, reviews the main provisions of the ACA related to insurance coverage and healthcare costs, including what is known so far about their impact. It also discusses the recent Republican attempt to ‘repeal and replace’ the law.

One important component of Obamacare – a dependent coverage provision for young people – took effect in 2010. It allowed dependents to remain on parents’ insurance coverage until age of 26. This column discusses the impact of this coverage on a number of outcomes. The results indicate that provision improved young adults’ health care access, did not influence preventive care utilisation, had mixed effects on health behaviours, and improved some but not all dimensions of self-assessed health.

Market-based mechanisms such as cap-and-trade can tackle externality problems more efficiently than command-and-control regulations. However, politicians in the US and Europe have retreated from cap-and-trade in recent years. This column draws a parallel between Republicans’ abandonment of market-based environmental regulation and their recent disavowal of mandatory health insurance. The author argues that in practice, the alternative to market-based regulation is not an absence of regulation, but rather the return of inefficient mandates and subsidies.
