ABSTRACT
This research shows that the ACA health insurance exchanges have generated more merger activity in the health insurance market. The impact is robust to control for an extensive set of factors suggested by both neoclassical and behavioural frameworks. The economic impact of this ACA provision is substantial with 3.8 more months of unusually high merger activity or 52 more merger bids per year.
