Measuring The Welfare Effects Of Price Changes

This book provides a general framework for the use of theoretical contributions in empirical works, addressing the question of what is the effect of a price change on household well-being. This simple question is one of the most relevant and controversial questions in microeconomic theory and one of the main sources of errors in empirical economics. In particular, this book aims to 1) Review the essential microeconomics literature since the first seminal papers by Hicks in the 1930s; 2) Organize and simplify this literature in a way that can be easily used by analysts with different backgrounds providing algebraic, geometric and computational illustrations; 3) identify and measure the essential differences across methods and test how these differences affect empirical results; 4) Provide guidelines for the use of alternative approaches under imperfect information on utility, demand systems, elasticities and more generally incomes and quantities; 5) Provide computational codes in Stata for the application of all methods. The focus of the book is on developing economies and the poor, and the assumptions made will relate primarily to these countries and group of people, presumably the main policy focus of international organizations and national governments.

World Bank Discussion Paper No. 273. This paper discusses the problems of measuring welfare changes caused by large price increases or decreases in the power sector--for example, when tariffs are raised to cover long-term costs or when electrificat

Hans-Werner Sinn, Munich, West Germany This book contains 15 papers presented at a conference in Neresheim, West Ger many, in June 1986. The articles were selected by anonymous referees and most of them have undergone substantial revisions since their presentation. The common topic is measurement of welfare, both from efficiency and from equity perspectives. For many economists, welfare is a diffuse, arbitrary and am biguous concept. The papers collected in this book show that this view is not justified. Though not beyond all doubt, welfare theory today is crisp and clear, offering fairly straightforward measuring concepts. It even comes up with numbers that measure society's advantage or disadvantage from specific policy options in monetary units. Politicians get something they can intuitively understand and argue with, and they do not have to be afraid that all this is metaphysics or the result of the scientist's personal value judgements. Some economists, whom I would classify as belonging to the "everything is optimal" school, would claim that providing politicians with numerical welfare measures is superfluous or even dangerous. The world is as it is, and any attempt to give policy advice can only make things worse. I do not share this view. There are good policies and there are bad ones, but it may not be easy to distinguish between them. There is a role for consulting politicians, Dr.

The Welfare Economics of Public Policy is a great book that should be of interest to all economists interested in applied welfare analysis. It is a good reference book for economists studying the effects of public policy. Finally, it should be a useful textbook for students studying economic policy and applied welfare economics. Jean-Paul Chavas, American Journal of Agricultural Economics . . . a very comprehensive overview of the state of the art in welfare economics. It can be used as a teaching book for advanced students as well as a reference volume for researchers. This duality of possible uses is supported by the fact that very complex issues are presented in an easily readable manner. More technical aspects are then outlined in the appendices of the relevant chapters, offering colleagues the option to study formal considerations in more detail. . . a welcome addition to and expression of the knowledge base of agricultural economics. Stefan Mann, Journal of Agricultural Economics I am absolutely delighted that the authors have revised and republished this text. I have used the previous version for years in my graduate environmental economics course; usually I had to share the one copy I have with students and I felt it was a shame that these students did not have the opportunity to purchase the book since every serious environmental economist should have this volume on their shelf. It has been a continuous reference volume for me over the years and I am sure this is true of many others in the discipline. In the field of applied welfare analysis (spanning environmental economics, international trade, agricultural policy, etc.) there is no need for further elaboration when Just, Hueth and Schmitz is referenced. Everyone knows the book that is being referred to: the bible of applied welfare economics. Catherine Kling, Iowa State University, US For the record, I am one of the people who requested that the authors revise and re-issue their textbook. It is an extremely valuable book for applied economists; as with the previous edition, I will use it extensively in two of my courses and consult it frequently in my own research endeavors. Richard Adams, Oregon State University, US The original book is very well known in our profession and is still used in many classes. It will be wonderful to have a revised edition of this classic book. Colin Carter, University of California, Davis, US This outstanding text, a follow-up to the authors award-winning 1982 text, provides a thorough treatment of economic welfare theory and develops a complete theoretical and empirical framework for applied project and policy evaluation. The authors illustrate how this theory can be used to develop policy analysis from both theory and estimation in a variety of areas including: international trade, the economics of technological change, agricultural economics, the economics of information, environmental economics, and the economics of extractive and renewable natural resources. Building on willingness-to-pay (WTP) measures as the foundation for applied welfare economics, the authors develop measures for firms and households where households are viewed as both consumers and owner/sellers of resources. Possibilities are presented for (1) approximating WTP with consumer surplus, (2) measuring WTP exactly subject to errors in existing econometric work, and (3) using duality theory to specify econometric equations consistent with theory. Later chapters cover specific areas of welfare measurement under imperfect competition, uncertainty, incomplete information, externalities, and dynamic considerations. Applications are considered explicitly for policy issues related to information, international trade, the environment, agriculture, and other natural resource issues. The Welfare Economics of Public Policy is ideal for graduate and undergraduate courses in applied welfare economics, public policy, agricultural policy, and environmental economi

Professor McKenzie proposes and formulates a method composed of operational procedures designed to facilitate the evaluation of economic projects and policies. This method is discussed fully, illustrated by simple examples, and compared with alternative procedures. An outline of a computer program that enables readers to undertake their own calculations is included. In order to present the approach clearly, the author provides an exposition of the fundamental ideas and the main alternative approaches to the problem. These rely on various forms of index numbers and consumer surplus. However, as is well known, such measures are not capable of correctly ordering the various alternatives under consideration, except under highly unrealist assumptions. In this book the author suggests the abandonment of this traditional approach based on the concept of 'willingness-to-pay' or the conpensating variation. Instead, the measure that Samuelson has called the 'money-metric' should become the cornerstone of applied welfare economics.
