Olugbenga: The good news is that a great deal of economic growth has been happening across 17 countries of Africa, as this new book by USAID chief economist Steve Radelet (available free online) illustrates: http://www.cgdev.org/content/publications/detail/1424378 Two notable things about that growth: 1) None of it comes from a "growth formula". It arises from different sources in different places. 2) It does not arise from intensive village-level package interventions by outside agencies. Such interventions are bogged down in a long history of failure --- as we discuss in our paper. That long history of failure places a heavy burden of proof on the Millennium Villages Project, which is why we consider evaluation of the Project's public claims to be so important.
