The federal Office of Child Support Enforcement awarded grants to eight states to design and implement interventions as part of the Behavioral Interventions for Child Support Services (BICS) project. The sites will use insights from behavioral economics to improve the operations of child support programs. A concurrent grant is funding technical assistance and evaluation services in conjunction with each site. This work includes identifying problems of interesting, diagnosing behavioral bottlenecks, designing behavioral interventions to address these bottlenecks, and using randomized control trials to evaluate the impact of these interventions. MEF is a subcontractor to MDRC on this project. MEF staff are leading the cost and implementation study and are serving as leads for three sites.
