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.

Paul Collier’s 2007 book, The Bottom Billion: Why the Poorest Countries are Failing and What Can Be Done About It, changed the way we think about poverty and development. Collier argued that the majority of the 5-billion people in the "developing world" live in countries with sustained high growth rates and would eventually escape from poverty. The rest—the bottom billion—live in 58 small, poor, often land-locked countries that are growing very slowly or not at all. These countries, stuck in poverty traps, should be the focus of foreign aid, Collier argued.
