Determinants of Long-Term Unions: Who Survives the “Seven Year Itch”?

Most studies of union formation and dissolution identify probabilities of union transitions in the next year; they do not reveal the likelihood of forming unions and maintaining them for the long-term. We use NLSY79 data to estimate a series of choice models in which never-married women decide when to cohabit or marry, cohabitors decide when to separate or marry, first-married women decide when to divorce, and women with prior unions advance through similar stages. We use the estimates to simulate women’s union-related outcomes from age 18 to 42, and then predict probabilities of following long-term paths. We find that cohabitation substantially increases the probability of entering and maintaining a long-term union (defined as 8+ years) because the high chance of entry outweighs the low chance of stability. We also find that race and skill affect probabilities of long-term unions, but determinants that can be manipulated by public policy do not.
