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.

Expectations are high regarding the potential benefits of public-private partnerships (PPPs) for infrastructure development in low-income countries. The development community, led by the G20, the United Nations, and others, expects these partnerships between goverments and private companies in infrastructure service provision to aid "transformational" mega-projects, as well as efforts to achieve the Sustainable Development Goals. Yet PPPs have been widely used only since the 1990s, and discussion of their efficacy is still dominated by best-practice guidance, academic studies that focus on developed countries, or ideological criticism. Meanwhile, practitioners have quietly accumulated a large body of empirical evidence on the actual performance of PPPs. The purpose of this book is to summarize and consolidate what this critical mass of evidence-based research indicates about PPPs in low-income countries, and thereby develop a more realistic perspective on the practical value of these mechanisms. With a primary focus on Sub-Saharan Africa, though drawing on critical insights from other regions, it demonstrates that the benefits of such partnerships will only be realised if expectations remain modest and projects are subject to transparent evaluation and competition.
