Assessing natural resource damages often requires the use of nonmarket valuation techniques that were developed for use in benefit-cost analyses. Natural resource damage assessment dramatically changes the context for applying them. Two aspects of this context are especially important. First, damages are to be measured by the monetary value of the losses people experience, including their use and nonuse values, because of injuries to natural resources---a process requiring careful delineation of how the injuries connect to the resource's services. Second, a single identified entry---not generalized, anonymous taxpayers---must pay damages based on what is measured, and evaluations of the measurement techniques take place not in agency meeting rooms but in courtrooms.Contributors to Valuing Natural Assets examine the ways in which requirements for damage assessment change how the measures are used, presented, received, and defended. Drawing upon their personal involvement with the process and the research issues it has raised---both in providing analysis for defendants or plaintiffs in damage assessment cases and in writing for academic journals---their chapters reflect individual research programs that temper the rigorous demands of scholarship with the equally demanding standards of litigation.

A Shock to the System is a guide to the decisions that will be faced by electricity providers, customers, and policymakers. Produced by a team of analysts at Resources for the Future, this concise and balanced work provides background necessary to understand the increasing role of competition in electricity markets. The authors introduce important concepts and terminology, and offer the history of public policy regarding electricity. They identify the significant proposals for implementing competition, and examine the potential consequences for regulation, industry structure, cost recovery, and the environment.

Contingent valuation (CV) measures what is called passive use value or existence value. The CV method has been used to measure the benefits of environmental policy actions. CV measures of economic value rely on choice. In CV studies, choices are posed to people in surveys; analysts then use the responses to these choice questions to construct monetary measures of value. The specific mechanism used to elicit respondents' choices can take a variety of forms, including asking survey respondents whether they would purchase, vote, or pay for a program or some other well-defined object of choice. It can also be a direct elicitation of the amount each respondent would be willing to pay (WTP) to obtain an object of choice or the amount each respondent would be willing to accept (WTA) in compensation to give it up. This volume is composed of three sections. The first section provides background into the issues underlying the public and academic discussion regarding CV and the reliability of CV estimates of economic value. In addition, this section reviews the theory underlying the measurement of economic value and discusses those aspects of the theory most relevant to CV. The second section focuses on issues that have formed the core of the CV discussions including: sensitivity of WTP estimates to the size of the program offered, tests for theoretical consistency of CV results, and the sensitivity of results to context and numerous other features of the survey and its administration. The final section addresses the application of CV to actual economic valuation tasks and discusses the types of practical problems the CV researcher will encounter.
