This paper uses U.S. Census data from 1980, 1990 and 2000 to estimate synthetic-cohort life cycle effects of fertility on women's and couples' labor supply. Multiple births are used as an instrument to control for unobserved heterogeneity. For single women, the causal effect of fertility has declined significantly over time. Couples, however, have become more specialized along traditional lines, with married men tending to increase labor earnings rather than reduce hours worked.
