Sharing care and sharing costs? Child support and child-related expense-sharing post-separation in Finland and Wisconsin, US

This study analyzes the associations between post-separation child living arrangements and child support outcomes and expense sharing in two contrasting welfare states: Finland and the United States (Wisconsin). The extent to which parents share the economic responsibility of the child after separation varies across countries. As shared care arrangements become more prevalent, traditional child support arrangements may become less common. Survey data collected in Finland (2019) and Wisconsin (2020) from separated or divorced parents are utilized in this study, and standard logistic and OLS regression models are used to investigate the relationship between sole and shared care arrangements and child support outcomes and expense sharing. The findings demonstrate that shared care arrangements are associated with a reduced likelihood of having a formal child support order and an increased likelihood of sharing child-related expenses in Finland and Wisconsin. Thus, shared care arrangements are linked to a decrease in formal child support orders and an increase in expense sharing. The results indicate a reduced reliance on formal child support orders and an increased willingness to privately share child-related expenses; findings reflect changing societal practices regarding the economic aspects of child rearing in separated or divorced families.
