First published in 1988. This book has grown from a research workshop that began at the University of North Carolina under the direction of Maynard Hufschmidt. Professor Hufschmidt's long-held interest in the incorporation of environmental and other social values into benefit-cost analysis led to a research project entitled, "e;The Role of Environmental Indicators in Water Resource Planning and Policy Development,"e; funded by the U.S. Department of the Interior. That project brought together the authors of this volume for a two-year period during which the groundwork for this book was laid.
