The Medicaid Notch, Labor Supply, and Welfare Participation: Evidence from Eligibility Expansions

I assess the impact of losing public health insurance on labor market decisions of women by examining a series of Medicaid eligibility expansions targeted toward young children. These targeted expansions severed the historical tie between AFDC and Medicaid eligibility. The reforms allowed a mother's earnings to increase without losing public health insurance for her young children. Increasing the income limit for Medicaid resulted in a decrease in AFDC participation and an increase in labor force participation among these women. The effects were large for ever married women, and negligible for never married women.
