Almost 5 years ago we began working together on research for the U.S. Environmental Protec­ tion Agency (EPA) to measure the benefits of water quality regulations. EPA had awarded a contract to Research Triangle Inst~ute (RTIl in response to a proposal that Bill wrote on measuring these benefits. After meeting with the EPA project officer, Dr Ann Fisher, the basic outlines of what would become this research were framed. Upon the suggestion of Bob Anderson, then chief of the Benefits Branch at EPA, we selected the Monongahela River as the focal point of a case study that would compare alternative benefit measurement approaches. Exactly how this case study would be done remained vague, but Ann urged that there be a survey and that nonuse benefits be included in the question­ naire design. Of course, Bill agreed. At the same time, Kerry was independently working on a review article that tied together some of the loose threads in the option value literature. He had also been thinking about how to measure option value, as well as working on ways to generalize the travel cost approach for estimating benefits of site attributes. Glenn Morris at RTI suggested that Bill have lunch with him and Kerry and that they could talk about Bill's research to see if there were any mutual interest. Over the lunch and Bill's ever present dessert in a Chapel Hill restaurant, we found out just how much we have in common.

The transfer study, a technique used in cost-benefit analysis, is an increasingly important tool used by government agencies to assess environmental regulatory policy. This innovative book develops protocols for using the transfer method to approach environmental problems and introduces several significant conceptual and methodological advances that refine the transfer process.The transfer approach to quantitative policy analysis adapts information and data from existing studies and so provides an economical way to assess potential benefits and costs for projects. The book presents a detailed framework for examining the transfer of information, outlines the basic steps of the method, and discusses solutions to frequently encountered problems. It then illustrates the method with an extensive case study of environmental externalities from electricity generation. This case study provides the opportunity to discuss salient aspects of the transfer method in more detail, including conceptual principles, the quality of original studies, empirical difficulties and estimation techniques. It also demonstrates the use of state-of-the-art techniques such as meta analysis to synthesise and transfer information from multiple studies and assesses the reliability of the transfer estimates with repeated computer simulations, a technique known as Monte Carlo analysis.Environmental Policy Analysis with Limited Information will appeal to environmental policy analysts and managers as well as environmental economists.
