The contributions cover five areas of environmental economics: policy instru­ ments, cost- benefit analysis, cost-efficiency, contingent valuation and experimental economics. Each area is worthy of a book by itself, but here we have made a point of focusing on problems that seem directly applicable to the pressing policy issues of today. Thus, the contributors address topics that are directly relevant to interna­ tional and regional policy making, as well as those that are linked to development of supporting information systems (e.g. resource accounting). In addition, the con­ tributions seek to provide high- level applications of measurement techniques as well as pertinent critiques of these methods. The next section provides a summary overview of the book.
