Beginning in 2015, the Employer Shared Responsibility Provision of the Patient Protection and Affordable Care Act (ACA) required large employers to offer affordable health insurance to their full-time employees or pay a penalty.

The authors examine changes in offer and eligibility of employer-sponsored insurance (ESI) across major occupations and low-earning occupations. Are workers in low-earning occupations benefiting from expanded offering of ESI?
