"A few years into sub-Saharan Africa’s renaissance, there were the natural doubts. Economists had competed for so long to explain the region’s growth tragedy that good news was a shock. But now, more than a decade into the revival, the good news has grown better. The lesson is that sound policies can make a difference even in the least promising of settings. Defeatists everywhere, cheer up. (...) Less than 20 years ago, the conventional wisdom was that landlocked, ethnically divided countries battling the burdens of tropical disease might never advance. Today, there is no guarantee of future progress. But the fatalistic talk of an African growth tragedy has been proved wrong".
Sebastian Mallaby, "Africa is hooked on growth" (Financial Times).
