Obamacare doesn't appear to have led to people shifting to part-time work, says a new study.

The study, led by Asako Moriya, an economist at the Center for Financing, Access and Cost Trends at the Agency for Healthcare Research and Quality, examined work trends from the Current Population Survey from 2005-15, including work hours at firms, stated reasons for working part-time, age, education, and health insurance status.

The study sought to assess claims by critics of the Patient Protection and Affordable Care Act, as well as nonpartisan analysts such as the Congressional Budget Office, that the health law creates a major incentive for workers to quit their jobs or reduce their hours because they can more easily acquire insurance without an employer.
