The reform of child support arrangements, including their treatment by the welfare system, has been on the policy agenda in a number of countries in recent years. This paper simulates the impact of a reform that recently has been implemented in the United Kingdom. The analysis is based on estimates of a model of discrete choice labor supply for a sample of U.K. lone mothers. We suggest that reform will induce a major reduction in welfare expenditures on lone mothers and a significant rise in their labor force participation due to greater work incentives associated with the changes.
