Impact Evaluations and the 3ie: William Savedoff

Efforts to design better aid programs often are hampered by the failure to evaluate what works—and what doesn’t—in existing programs. Today, the International Initiative for Impact Evaluation and other important efforts are helping fill the evaluation gap.

My guest this week is senior fellow Bill Savedoff. He was a member of the Center for Global Development’s 2004 Evaluation Gap Working Group, led by Ruth Levine, that urged and helped create a new institution for impact evaluation: the International Initiative for Impact Evaluation, or 3ie (“Triple I E”). Following a recent CGD speech by Esther Duflo on the importance of impact evaluation, I sat down with Bill to talk about how new impact evaluations are shaping development projects and policy.

Evaluating the Millennium Villages: Michael Clemens and Gabriel Demombynes

An aquaculture project in Bar Sauri, Kenya.In development, it's good to try new, innovative ideas-- but even better to know whether or not they work. My guests this week are Michael Clemens, senior fellow at the Center for Global Development, and Gabriel Demombynes, a senior economist at the World Bank, based in Nairobi, Kenya. They have written a new paper in which they argue that one very high profile development program, the Millennium Villages Project, isn’t being evaluated in a way that would provide clear evidence of its impacts. They propose a better way to evaluate the project.
