Note: 1997, 2002-3, 2007 waves of the PSID-CDS are used. N denotes the number of children. All regressions include the controls for child's sex, race, lifetime family income, mother's age and marital status at child's birth, cigarette excise tax at child birth, a set of indicators for birth order, home environment, and mother's education. Robust standard errors in parentheses are clustered at the mother level.
