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.

Contingent valuation is a survey-based procedure that attempts to estimate how much households are willing to pay for specific programs that improve the environment or prevent environmental degradation. For decades, the method has been the center of debate regarding its reliability: does it really measure the value that people place on environmental changes? Bringing together leading voices in the field, this timely book tells a unified story about the interrelated features of contingent valuation and how those features affect its reliability. Through empirical analysis and review of past studies, the authors identify important deficiencies in the procedure, raising questions about the technique's continued use. Individual chapters investigate how respondents answer questions in contingent valuation surveys, with a particular focus on how the procedure's estimates change based on the costs that the researcher specifies, the payment mechanism, and the scope of the environmental improvement. Other issues covered include whether the survey respondents make trade-offs between the program costs and benefits; and whether corrections can be applied to account for any misunderstanding of the questions by respondents and for the hypothetical nature of the survey. This book will appeal to environmental economists and students in environmental and resource economics. Government staff at environmental agencies and survey researchers will benefit from the close analysis of previous applications. Contributors include: J. Burrows, H.M. Chan, L. Daniel, W.

This book provides a systematic review of those economic approaches for valuing the environment and natural resources that use information on what people do, not what they say. The authors have worked on models of revealed preferences for valuing environmental and natural resources for several decades. The book provides a candid review of the major conceptual challenges and an exploration of neglected issues in the literature.

The primary aim of this reference volume is to provide an accessible and comprehensive review of current methods used to address resource evaluation and environmental as well as climate issues, and in a manner easily understood by decision-makers and the non-economists interested in environmental policy matters. Theoretical insight and empirical observations from various countries will be presented and recommendations on sustainable environmental decision-making will be given. Natural resource managers, environmental and climate decision-makers, government policy makers, and economics scholars will all find this volume to be an essential reference.

Nutrient recycling, habitat for plants and animals, flood control, and water supply are among the many beneficial services provided by aquatic ecosystems. In making decisions about human activities, such as draining a wetland for a housing development, it is essential to consider both the value of the development and the value of the ecosystem services that could be lost. Despite a growing recognition of the importance of ecosystem services, their value is often overlooked in environmental decision-making. This report identifies methods for assigning economic value to ecosystem servicesâ€"even intangible onesâ€"and calls for greater collaboration between ecologists and economists in such efforts.
