A model of child support and the underground economy

We develop and estimate a model of the informal and formal employment decisions of American noncustodial fathers who have never married the mother of their child, as well as the paternity establishment decisions of the mothers. Fathers may evade child support payment through informal child support payments to induce the mother not to cooperate with the child support authorities or through underground work. To estimate the model, we use data drawn from the Fragile Families dataset and a discrete model of no work, part-time work and full-time work in both sectors, as well as paternal child support payment. Simulation results indicate that an increase in the order amount leads to small but statistically significant decreases in formal child support, as well as an increase in underground work.

► We develop a model of the effect of child support on paternal underground work.
► High order amounts are associated with a lower probability of formal child support.
► High orders are also associated with a small increase in underground work.
