The Affordable Care Act aims to substantially increase public health insurance eligibility among low-income childless adults. The literature suggests that public health insurance may have important implications for labor market participation. With data from the March supplement to the Current Population Survey, difference-in-difference multivariable regression modeling is used to examine the association between state-level public health insurance expansions and the likelihood of full-time employment, part-time employment, and not working among eligible childless adults. Results indicate that public health insurance eligibility is associated with a 2.2 percentage point decrease in full-time employment, a 0.8 percentage point increase in the likelihood of part-time employment, and a 1.4 percentage point increase in the likelihood of not working. These associations were greatest among those with worse health and those aged from 50 to 64 years. This analysis provides important insights into the potential labor market repercussions of health insurance expansions under the Affordable Care Act.
