Brief summary

This randomized evaluation used behaviorally-informed letters to increase health insurance take-up on the Affordable Care Act (ACA) Marketplaces.

Detailed description

During Open Enrollment Periods for the ACA Marketplaces, qualifying individuals can purchase health insurance plans through the Federal Health Insurance Marketplace (FHIM). As of early February 2015, many people had visited HealthCare.gov and started an online account, but not yet selected a plan. The Department of Health and Human Services (HHS), in collaboration with the Office of Evaluation Sciences (OES), developed and sent letters to assist these individuals with completing their enrollment before the deadline. To evaluate the effect of the letters, the team used a randomized controlled trial.
