The Economist reviews Jeffrey Sachs’ new book “The End of Poverty: Economic Possibilities for Our Time.” The Economist writes: “Aid can work, the book argues fervently, but you have to think big. Even when conditions are such that aid is likely to succeed (when standards of governance are adequate, when supporting policies are in place, and so forth) rich-country governments have been mean, fickle and short-sighted about aid. Find those cases where aid can work, says Mr Sachs, spend generously, and sustain it. This central point is persuasively hammered home.”
