It looks at a broad movement toward limited network plans in Massachusetts in 2011, when state employees got a three-month “premium holiday” if they switched from more traditional coverage to the lower-cost option.

State employees who chose to switch reduced their health care spending by 36 percent.

“Clearly, this was a big cost-saver for the state,” says study co-author Jon Gruber.

Gruber, who had a hand in creating both the Massachusetts coverage law and the Affordable Care Act, claims the political implications of this Massachusetts limited network experiment are profound.

“There’s a lot of discussion about ObamaCare leading to more ‘limited’ choices,” says Gruber, and “isn’t that a shame.” But Gruber says people in these plans “don’t appear to be suffering.” Continue reading
