Unique longitudinal measures from Nepal allow us to link both mothers’ and fathers’ reports of their marital relationships with a subsequent long-term record of their children’s behaviors. We focus on children’s educational attainment and marriage timing because these two dimensions of the transition to adulthood have wide-ranging, long-lasting consequences. We find that children whose parents report strong marital affection and less spousal conflict attain higher levels of education and marry later than children whose parents do not. Furthermore, these findings are independent of each other and of multiple factors known to influence children’s educational attainment and marriage timing. These intriguing results support theories pointing toward the long-term intergenerational consequences of variations in multiple dimensions of parents’ marriages.
