This volume brings together essays by thirty-four leading economists about the most important things they have learnt from their research that relate to poverty. The essays range from the impact of colonialism and globalization to the future of micro-credit and the quest for new vaccines.

Understanding Poverty

An encouraging account of the potential of foreign aid to reduce poverty and a challenge to all aid organizations to think harder about how they spend their money. With more than a billion people now living on less than a dollar a day, and with eight million dying each year because they are simply too poor to live, most would agree that the problem of global poverty is our greatest moral challenge. The large and pressing practical question is how best to address that challenge. Although millions of dollars flow to poor countries, the results are often disappointing. In Making Aid Work, Abhijit Banerjee—an "aid optimist"—argues that aid has much to contribute, but the lack of analysis about which programs really work causes considerable waste and inefficiency, which in turn fuels unwarranted pessimism about the role of aid in fostering economic development. Banerjee challenges aid donors to do better. Building on the model used to evaluate new drugs before they come on the market, he argues that donors should assess programs with field experiments using randomized trials. In fact, he writes, given the number of such experiments already undertaken, current levels of development assistance could focus entirely on programs with proven records of success in experimental conditions. Responding to his challenge, leaders in the field—including Nicholas Stern, Raymond Offenheiser, Alice Amsden, Ruth Levine, Angus Deaton, and others—question whether randomized trials are the most appropriate way to evaluate success for all programs. They raise broader questions as well, about the importance of aid for economic development and about the kinds of interventions (micro or macro, political or economic) that will lead to real improvements in the lives of poor people around the world. With one in every six people now living in extreme poverty, getting it right is crucial.

Making Aid Work

Understanding poverty and what to do about it, is perhaps the central concern of all of economics. Yet the lay public almost never gets to hear what leading professional economists have to say about it. This volume brings together twenty-eight essays by some of the world leaders in the field, who were invited to tell the lay reader about the most important things they have learnt from their research that relate to poverty. The essays cover a wide array of topics: the first essay is about how poverty gets measured. The next section is about the causes of poverty and its persistence, and the ideas range from the impact of colonialism and globalization to the problems of "excessive" population growth, corruption and ethnic conflict. The next section is about policy: how should we fight poverty? The essays discuss how to get drug companies to produce more vaccines for the diseases of the poor, what we should and should not expect from micro-credit, what we should do about child labor, how to design welfare policies that work better and a host of other topics. The final section is about where the puzzles lie: what are the most important anomalies, the big gaps in the way economists think about poverty? The essays talk about the puzzling reluctance of Kenyan farmers to fertilizers, the enduring power of social relationships in economic transactions in developing countries and the need to understand where aspirations come from, and much else. Every essay is written with the aim of presenting the latest and the most sophisticated in economics without any recourse to jargon or technical language.
