This book is an examination of the nature of economic explanation. The opening chapters introduce current thinking in the philosophy of science and review the literature on methodology. Professor Blaug then turns to the troublesome question of the logical status of welfare economics, giving the reader an understanding of the outstanding issues in the methodology of economics. This is followed by a series of case studies of leading economic controversies, which shows how controversies in economics may be illuminated by paying (...) attention to questions of methodology. A final chapter draws the strands together and gives the author's view of what is wrong with modern economics. This book is a revised and updated edition of a classic work on the methodology of economics, in which Professor Blaug develops his discussion of the latest developments in macroeconomics, general equilibrium theory and international trade theory. A new section on the rationality postulate is also added. (shrink)

Economics is today among the most influential of all professions. Economists alter the course of economic affairs and deeply affect the lives of current and future generations. Yet, virtually alone among the major professions, economics lacks a body of professional ethics to guide its practitioners. Over the past century the profession consistently has refused to adopt or even explore professional economic ethics. As a consequence, economists are largely unprepared for the ethical challenges they face in their work.The Economist's Oath challenges (...) the economic orthodoxy. It builds the case for professional economic ethics step by step-first by rebutting economists' arguments against and then by building an escalating positive case for professional economic ethics. The book surveys what economists do and demonstrates that their work is ethically fraught. It explores the principles, questions, and debates that inform professional ethics in other fields, and identifies the lessons that economics can take from the best established bodies of professional ethics. George DeMartino demonstrates that in the absence of professional ethics, well-meaning economists have committed basic, preventable ethical errors that have caused severe harm for societies across the globe. The book investigates the reforms in economic education that would be necessary to recognize professional ethical obligations, and concludes with the Economist's Oath, drawing on the book's central insights and highlighting the virtues that are required of the "ethical economist."The Economist's Oath seeks to initiate a serious conversation among economists about the ethical content of their work. It examines the ethical entailments of the immense influence over the lives of others that the economics profession now enjoys, and proposes a framework for the new field of professional economic ethics.

This book shows through argument and numerous policy-related examples how understanding moral philosophy can improve economic analysis, how moral philosophy can benefit from economists' analytical tools, and how economic analysis and moral philosophy together can inform public policy. Part I explores the idea of rationality and its connections to ethics, arguing that when they defend their formal model of rationality, most economists implicitly espouse contestable moral principles. Part II addresses the nature and measurement of welfare, utilitarianism and cost-benefit analysis. Part (...) III discusses freedom, rights, equality, and justice - moral notions that are relevant to evaluating policies, but which have played little if any role in conventional welfare economics. Finally, Part IV explores work in social choice theory and game theory that is relevant to moral decision making. Each chapter includes recommended reading and discussion questions. (shrink)

It is widely believed that cost-sharing - charging a subsidized, positive price - for a health product is necessary to avoid wasting resources on those who will not use or do not need the product. We explore this argument in the context of a field experiment in Kenya, in which we randomized the price at which pregnant women could buy long lasting anti-malarial insecticide-treated nets (ITNs) at prenatal clinics. We find no evidence that cost-sharing reduces wastage on those that will (...) not use the product: women who received free ITNs are not less likely to use them than those who paid subsidized positive prices. We also find no evidence that cost-sharing induces selection of women who need the net more: those who pay higher prices appear no sicker than the prenatal clients in the control group in terms of measured anemia (an important indicator of malaria). Cost-sharing does, however, considerably dampen demand. We find that uptake drops by 75 percent when the price of ITNs increases from 0 to $0.75, the price at which ITNs are currently sold to pregnant women in Kenya. We combine our estimates in a cost-effectiveness analysis of ITN prices on infant mortality that incorporates both private and social returns to ITN usage. Overall, given the large positive externality associated with widespread usage of insecticide-treated nets, our results suggest that free distribution to pregnant women is both more effective and more cost-effective than cost-sharing.
