Abstract

Fathers' multiple-partner fertility (MPF) is associated with substantially worse educational outcomes for children. We focus on children in fathers' second families that are nuclear: households consisting of a man, a woman, their joint children, and no other children. We analyze outcomes for almost 75,000 Norwegian children, all of whom lived in nuclear families until at least age 18. Children with MPF fathers are more likely than other children from nuclear families to drop out of secondary school (24% vs. 17%) and less likely to obtain a bachelor's degree (44% vs. 51%). These gaps remain substantial-at 4 and 5 percentage points, respectively-after we control for child and parental characteristics, such as income, wealth, education, and age. Resource competition with the children in the father's first family does not explain the differences in educational outcomes. We find that the association between a father's previous childless marriage and his children's educational outcomes is similar to that between a father's MPF and his children's educational outcomes. Birth order does not explain these results. This similarity suggests that selection is the primary explanation for the association between fathers' MPF and children's educational outcomes.
