Each year billions of dollars are spent on development programs with relatively few rigorous studies of whether they actually work. In 2004, CGD set out to address this lack of good quality impact evaluations and our recommendations led to the creation of the International Initiative for Impact Evaluation (3ie) in 2009. The number and quality of impact evaluations has risen significantly, but there is still a long way to go to make sure future development interventions are based on evidence of what works.
Each year billions of dollars are spent on thousands of programs to improve health, education and other social sector outcomes in the developing world. But very few programs benefit from studies that could determine whether or not they actually made a difference. This absence of evidence is an urgent problem: it not only wastes money but denies poor people crucial support to improve their lives.
This brief outlines the problems that inhibit learning in social development programs, describes the characteristics of a collective international solution, and shows how the international community can accelerate progress by learning what works in social policy. It draws heavily on the work of CGD's Evaluation Gap Working Group and a year-long process of consultation with policymakers, social program managers, and evaluation experts around the world.
CGD program director Ruth Levine argues that independent impact evaluation of anti-corruption programs will be crucial to the success of the new World Bank campaign against corruption. As corruption-fighting programs are put into place, she writes, donor and recipient countries should request and fund careful, credible and independent third party evaluations—then publish the results whether or not they make the funders and implementers look good.
