With rigorous economic research and practical policy solutions, we focus on the issues and institutions that are critical to global development. Explore our core themes and topics to learn more about our work.
In timely and incisive analysis, our experts parse the latest development news and devise practical solutions to new and emerging challenges. Our events convene the top thinkers and doers in global development.
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.
This paper analyzes some of the elements that cause the perception in the realm of social policy that too little evidence is produced and used on the impact of specific policies and programs on human development. They propose we develop Results-Based Social Policy Design and Implementation systems that focus public attention on better outcomes.
The authors examine the Millennium Villages Project (MVP), an experimental and intensive package intervention to spark sustained local economic development in rural Africa, to illustrate the benefits of rigorous impact evaluation. Estimates of the project’s effects depend heavily on the evaluation method.
