The percentage of children in the United States living apart from their biological father has increased, while public assistance for single mothers has diminished. This has resulted in a need to better understand and promote nonresident fathers' economic support of their children. In the present study the author used data from the Fragile Families and Child Wellbeing Study (N = 1,752) to examine how coparenting-the degree to which parents are mutually supportive and cooperative in raising their child-is related to nonresident fathers' monetary contributions. Results from pooled regression and fixed effects models indicate that coparenting is positively associated with fathers' likelihood of paying formal and informal child support and the amount of these payments. Findings from cross-lagged structural equation models suggest that the association between coparenting and fathers' payments is reciprocal but that coparenting has a stronger effect on fathers' payments than fathers' payments do on coparenting.
