New Study Examines Lessons From Massachusetts Health Insurance Exchanges
A new study examines Massachusetts’ experience with health insurance exchanges and finds that 1) insurance take-up declines as subsidies decline, 2) adverse selection occurs, and 3) uncompensated care appears to play in role in insurance enrollment rates and appears to benefit providers of uncompensated care.
The study, Subsidizing Health Insurance for Low-Income Adults: Evidence from Massachusetts and Implications for Future Health Reforms, was authored by Amy Finkelstein of MIT, Nathaniel Hendren of Harvard University, and Mark Shepard of Harvard Kennedy School.
These findings suggest that health care reforms that reduce subsidies will result in decreased enrollment, a sicker risk pool, and declining coverage rates for low income populations.
