This text 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 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.
