title: Crowd-out 10 years later: have recent public insurance expansions crowded out private health insurance?
abstract: Ten years ago, Cutler and Gruber [Cutler, D., Gruber, J., 1996. Does public health insurance crowdout private insurance? Quarterly Journal of Economics 111, 391-430] suggested that crowd-out might be quite large, but much subsequent research has questioned this conclusion. Our results using improved data and methods clearly show that crowd-out is still significant in the 1996-2002 period. This finding emerges most strongly when we consider family level measures of public insurance eligibility. We also find that recent anti-crowd-out provisions in public expansions may have had the opposite effect, lowering take-up by the uninsured faster than they lower crowd-out of private insurance.
