The Patient Protection and Affordable Care Act expands Medicaid and in-troduces health insurance subsidies, thereby changing work incentives for single mothers. To undertake an ex ante policy evaluation of the employment effects of the PPACA, I structurally estimate a model of labor supply and health in-surance choice exploiting existing variation in Medicaid policies. Simulations show that single mothers increase their labor supply at the extensive and the intensive margin by six and five percent, respectively. The PPACA leads to crowding-out of employer-sponsored health insurance of about 40 percent and increases single mothers' welfare by about $190 per month.
