Foreign aid is now a $100bn business and is expanding more rapidly today than it has for a generation. But does it work? Indeed, is it needed at all? Other attempts to answer this important question have been dominated by a focus on the impact of official aid provided by governments. But today possibly as much as 30 percent of aid is provided by Non-Governmental Organizations (NGOs), and over 10 percent is provided as emergency assistance. In this first-ever attempt to provide an overall assessment of aid, Roger Riddell presents a rigorous but highly readable account of aid, warts and all. Does Foreign Aid Really Work? sets out the evidence and exposes the instances where aid has failed and explains why. The book also examines the way that short-term political interests distort aid, and disentangles the moral and ethical assumptions that lie behind the belief that aid does good. The book concludes by detailing the practical ways that aid needs to change if it is to be the effective force for good that its providers claim it is.
