The Trump Effect: Postinauguration Changes in Marketplace Enrollment.

Journal Article (Journal Article)

Context

On January 20, 2017, President Donald Trump penned his first executive order, which aimed to "minimiz[e] the economic burden" of the Affordable Care Act, signaling his intent to make good on promises to repeal and replace the law. This executive order, along with concurrent changes in political messaging associated with the transition in power and reductions in HealthCare.gov advertising, lowered Health Insurance Marketplace enrollment at the end of the 2017 open enrollment period.

Methods

The authors used difference-in-differences and event-study models with weekly county-level Marketplace application data from 1,476 counties in 37 states to estimate the incremental enrollment loss in the postinauguration period.

Findings

Estimates indicate a population-weighted decline of over 700 applications per county-week during the final 2 weeks of the 2017 open enrollment period relative to 2016, corresponding to a nearly 30% decline in applications submitted. A more flexible event-study approach that better accounts for time shifting of enrollment across open enrollment periods found a similar decline of approximately 660 applications per county-week associated with the postinauguration period (-24%).

Conclusions

The lack of political support for the law by the incoming administration seemingly had an immediate and significant downward effect on Marketplace enrollment nationwide.
