May 2014The Effect of Public Insurance Coverage for Childless Adults on Labor Supply
with Laura Dague, Thomas DeLeire: w20111
This study provides plausibly causal estimates of the effect of public insurance coverage on the employment of non-elderly, non-disabled adults without dependent children (“childless adults”). We use regression discontinuity and propensity score matching difference-in-differences methods to take advantage of the sudden imposition of an enrollment cap, comparing the labor supply of enrollees to eligible applicants on a waitlist. We find enrollment into public insurance leads to sizable and statistically meaningful reductions in employment up to at least 9 quarters later, with an estimated size of from 2 to 10 percentage points depending upon the model used.
May 2011Estimates of Crowd-Out from a Public Health Insurance Expansion Using Administrative Data
with Laura Dague, Thomas DeLeire, Donna Friedsam, Daphne Kuo, Sarah Meier, Kristen Voskuil: w17009
We use a combination of administrative and survey data to estimate the fraction of individuals newly enrolled in public health coverage (Wisconsin’s combined Medicaid and CHIP program) that had access to private, employer-sponsored health insurance at the time of their enrollment and the fraction that dropped this coverage. We estimate that after expansion of eligibility for public coverage, approximately 20% of new enrollees had access to private health insurance at the time of enrollment and that only 8% dropped this coverage (with the remaining 12% having both private and public coverage). We also identify an “upper bound” estimate, which suggests that the percentage of new enrollees with private insurance coverage at the time of enrollment is, at most, 27%. These estimates of crowd-o...
