Over the last 30 years, the tenet of promoting self-sufficiency through work has become one of the primary objectives of many social welfare policies in the United States. Using the Panel Study of Income Dynamics, the author asks if a mother's work hours influence her daughter's teenage fertility. The findings suggest a negative relationship, with the largest effects for the daughters of mothers who work more than 1,000 hours per year. Results among AFDC recipients suggest that an increase in a mother's work hours from zero to 20 hours per week reduces her daughter's probability of a teen birth by 33 percent.
