Provided for over 60 years, and expanding more rapidly today than it has for a generation, foreign aid is now a $100bn business. But does it work? Indeed, is it needed at all? In this first-ever, overall assessment of aid, Roger Riddell provides a rigorous but highly readable account of aid, warts and all.

Assessing Aid determines that the effectiveness of aid is not decided by the amount received but rather the institutional and policy environment into which it is accepted. It examines how development assistance can be more effective at reducing global poverty and gives five mainrecommendations for making aid more effective: targeting financial aid to poor countries with good policies and strong economic management; providing policy-based aid to demonstrated reformers; using simpler instruments to transfer resources to countries with sound management; focusing projects oncreating and transmitting knowledge and capacity; and rethinking the internal incentives of aid agencies.
