Do premium tax credits increase private health insurance coverage? Evidence from the 2006 Massachusetts health care reform

- First study to examine effects of premium tax credits in Massachusetts.
- Premium tax credits appear increase private health insurance.
- Regression discontinuity could be useful to similar tax credits in the ACA.

I use the Current Population Survey March Supplement and a regression discontinuity design to demonstrate a positive impact of premium tax credits, implemented as a part of the 2006 health reform in Massachusetts, on non-group private health insurance coverage.
