A Cost-Benefit Analysis of Early Childhood Intervention: Evidence from an Experimental Evaluation of the Incredible Years Parenting Program.

A number of researchers and policy makers have recently argued that the most effective way of dealing with long-run disadvantage and the intergenerational transmission of poverty is through early childhood intervention and in particular policies aimed at supporting the family. This study was part of a randomised evaluation of the Incredible Years Program, which is aimed at improving the skills and parenting strategies of parents who have children with conduct problems. The results show that the treatment significantly reduced behavioural problems in young children. Furthermore our detailed cost analysis, when combined with a consideration of the potential long-run benefits associated with the programme, suggest that the long-run rate of return to society from this program is likely to be relatively high
