Valuing Environmental Benefits Using The Contingent Valuation Method

The questionnaire-based Contingent Valuation Method (CVM) asks people what would they be willing to pay for an environmental good or attribute, or willing to accept for its loss. These papers consider the real value of such surveys.

Economists and others have long believed that by balancing the costs of such public goods as air quality and wilderness areas against their benefits, informed policy choices can be made. But the problem of putting a dollar value on cleaner air or water and other goods not sold in the marketplace has been a major stumbling block. Mitchell and Carson, for reasons presented in this book, argue that at this time the contingent valuation (CV) method offers the most promising approach for determining public willingness to pay for many public goods---an approach likely to succeed, if used carefully, where other methods may fail. The result of ten years of research by the authors aimed at assessing how surveys might best be used to value public goods validly and reliably, this book makes a major contribution to what constitutes best practice in CV surveys. Mitchell and Carson begin by introducing the contingent valuation method, describing how it works and the nature of the benefits it can be used to measure, comparing it to other methods for measuring benefits, and examining the data-gathering technique on which it is based---survey research. Placing contingent valuation in the larger context of welfare theory, the authors examine how the CV method impels a deeper understanding of willingness-to-pay versus willingness-to-accept compensation measures, the possibility of existence values for public goods, the role of uncertainty in benefit valuation, and the question of whether a consumer goods market or a political goods market (referenda) should be emulated. In developing a CV methodology, the authors deal with issues of broader significance to survey research. Their model of respondent error is relevant to current efforts to frame a theory of response behavior and bias typology will interest those considering the cognitive aspects of answering survey questions. Mitchell and Carson conclude that the contingent valuation method can obtain valid valuation information on public goods, but only if the method is applied in a way that addresses the potential sources of error and bias. They end their book by providing guidelines for CV practitioners, a list of questions that should be asked by any decision maker who wishes to use the findings of a CV study, and suggestions for new applications of contingent valuation. Additional features include a comprehensive bibliography of the CV literature and an appendix summarizing more than 100 CV studies.

Contingent valuation is one of the means of incorporating socio-environmental considerations in cost–benefit analysis. The authors of this book have examined environmental valuation methods through the lens of cost–benefit analysis focused on three case studies in Japan: public parks, a bay wetland, and a recreational theme park. With implications for the world at large, the findings presented here serve as a valuable source of information on Japanese behavior regarding the valuation of environmental goods. New, alternative approaches and guidelines for cost–benefit analysis in the public and private spheres also are discussed. This volume makes an important addition to the library of all researchers and other scientists in the fields of environmental science and environmental economics.

The Handbook on Contingent Valuation is unique in that it focuses on contingent valuation as a method for evaluating environmental change. It examines econometric issues, conceptual underpinnings, implementation issues as well as alternatives to contingent valuation. Anna Alberini and James Kahn have compiled a comprehensive and original reference volume containing invaluable case studies that demonstrate the implementation of contingent valuation in a wide variety of applications. Chapters include those on the history of contingent valuation, a practical guide to its implementation, the use of experimental approaches, an ecological economics perspective on contingent valuation and approaches for developing nations. The Handbook also contains: P discussions of underlying theory both contingent valuation and conjoint analysis comparisons of real and hypothetical data using experimental approaches an examination of survey structure issues developing country focus critical essays concerning the ethical basis of contingent valuation. This new reference book will be warmly welcomed by academics in environmental economics, environmental professionals in government, consulting firms and NGOs. Graduate and undergraduate students in economics, environmental studies and environmental policy will also find this an ever valuable resource.

Economic values are increasingly used in policy analysis and legal settings. With the growing recognition that many of the things that benefit or harm people are outside the market system, have come increasing efforts to develop nonmarket valuation techniques. One such technique is the contingent valuation method (CVM). CVM seeks to value environmental and other nonmarket goods and services by asking individuals about their values using survey methods. These procedures are different from the `revealed-preference' methods that economists have historically employed to estimate economic values. Why depart from well-established revealed-preference procedures and apply a `stated-preference' method like CVM? For nonmarket goods and services, revealed-preference methods have two shortcomings that those applying CVM hope to avoid. First, revealed-preference methods involve econometric problems that have yet to be fully overcome. The second shortcoming of revealed-preference methods is that such methods, when applied to environmental amenities, are likely to be only partial measures of value. Given the tremendous interest that exists in economic values and the limitations of revealed-preference methods, it is not surprising that interest in CVM has grown rapidly. Environmental Resource Valuation reviews the application of CVM and compares American experiences in nonmarket evaluation with those in other countries.

This companion volume to Economic Instruments for Environmental Management presents essential information on the applications of economic valuation to environment and development. It draws on a three-year collaborative effort by research institutions around the world. Authoritative studies review the range of valuation methods used in developing economies, their purposes, the problems encountered and the quality of the results. Topics covered include the value of wildlife viewing, the conservation of rainforests, mangroves and coral reefs, supplying rural water, and controlling urban air pollution. The analysis reveals important methodological and contextual factors, highlighting key lessons and ways of strengthening future valuations. Written to be accessible to non-economists, the book provides source material for students and academics, and for policy-makers and professionals, using valuation methods to frame policy.

This volume considers, in depth, some valuation methods and aspects of cost benefit analysis, and policy making in environmental economics. Part I contains a number of contingent valuation studies for non-market assets. Part II consists of contributions on the valuation of health and life, and deals with the benefits of reduced morbidity from air pollution control. In Part III, cost benefit analysis for environmental policy-making is discussed in a disequilibrium setting, and in a macroeconomic context. Finally, Part IV deals with aspects of policy-making, particularly benefit estimation for complex policies, and the international aspects of transboundary air pollution in Europe. The book should not only appeal to students and researchers in university departments of economics and ``environmental sciences'' but also to those working in public organisations and associated advisory institutes which are concerned with environmental problems.
