In this issue brief, Dr. Anna Sommers and her research team at The Hilltop Institute (University of Maryland, Baltimore County) present findings about employer participation in New Mexico's State Coverage Insurance (SCI) program, a public/private partnership that provides access to subsidized health insurance for low-income uninsured adults (19 to 64 years old), who can sign up either independently or with sponsorship from a small employer (50 or fewer employees).  Dr. Sommers and her team point out that while overall SCI take-up has been strong, employer sponsorship remains low relative to the large number of small businesses in New Mexico.  The authors examine the concerns that small businesses identified with respect to SCI participation and point out that the most significant concerns identified--relating to the administrative burden of participation--are a result of the program's dependence on CHIP funding.
