Employer mandates to provide health benefits have become increasingly popular mechanisms for insurance coverage expansion, and are incorporated into many health reform proposals, including the U.S. Patient Protection and Affordable Care Act. Mandates of this type are popular because they allow policy makers to finance social policy without government funds, and in the case of a “pay-or-play” mandate such as the one in the Affordable Care Act, raise money from employers to finance coverage expansion. Economic theory and past research have suggested that in demographically identifiable groups who value the benefit at its cost, the incidence of such a mandate is likely to affect workers through reductions in wages or jobs (Gruber 1994, Summers 1989). Wage adjustment and employment effects hinge on employee valuation of the benefit and features of the labor market, such as the minimum wage or collective bargaining agreements. In addition to being of interest at a theoretical level, the impact of an employer mandate to provide health benefits is of policy relevance and the likely effect of the Affordable Care Act on jobs has been politically controversial (Pear 2011). In late 2006, San Francisco enacted ambitious healthcare legislation with a goal of attaining universal access to health care for the city’s residents. As part of the initiative, San Francisco implemented a “pay-or-play” employer mandate to finance health care for residents. This law provides a natural experiment to estimate how the labor market (employment and earnings) responds to a pay-or-play mandate. Beginning in 2008, the San Francisco Health Care Security Ordinance mandates firms with more than 20 employees to spend a minimum contribution per worker-hour on health benefits. Employers with 100 or more employees were required to contribute $1.76 per hour in health spending for each employee in 2008 (with subsequent annual increases of about 5%) while for smaller firms...
