From the abstract:
There has been speculation that the Affordable Care Act’s coverage provisions and employer mandate have led to an increase in part-time employment. Using the Current Population Survey for the period 2005–15, we examined data on weekly hours worked by firm size, reason for working part time, age, education, and health insurance. We found only limited evidence to support this speculation.
