I thought this might be of some interest. A profile of one of the economists who authored the book Poor Economics in the Guardian.
Until Poor Economics appeared last year, the debate about aid had been broadly polarised into two positions. On the left was Jeffrey Sachs, arguing that the single biggest factor keeping poor people poor is poverty. If foreign aid can lift them out of the poverty trap long enough to free them from the disease, ignorance and debt that thwart their potential, then pretty soon they will be able to solve their own problems for themselves. On the right, William Easterly argued that the real problem isn’t a poverty trap but aid itself, which creates a dependency culture that keeps the poor poor, and distorts their only real roadmap to prosperity – the free market.
