Early Evidence on the Effects of the Affordable Care Act on Part-Time Employment

Project Dates

09/18/2018 -


The Affordable Care Act (ACA) requires employers with at least 50 full-time -equivalent employees to offer "affordable" health insurance to employees working 30 or more hours per week. If employers do not comply with the mandate, they may face substantial financial penalties. Employers can circumvent the mandate by reducing employees' weekly hours below the 30-hour threshold, although only certain industries are likely to make widespread use of the tactic: those where short-hours part-time work is a feasible staffing strategy and where many employees work more than 30 hours but had not previously been offered health insurance. The goal of this project is to use monthly CPS data to examine the effects of the ACA on short-hours, part-time and involuntary part-time employment.
