Using longitudinal data covering 25 years from 1979 to 2004, the author examines the relationship between wives’ economic resources and the risk of marital dissolution. The author considers the effects of labor force participation, income, and relative income while accounting for potential endogeneity of wives’ economic resources. The extent to which wives’ economic resources are differentially related to marital disruption for Whites and Blacks is also ascertained. The author finds that the economic resources of women are tightly linked to the risk of divorce, both negatively and positively, for Whites but not for Blacks.
