This manual provides explanations on performing economic valuation using stated preference techniques. The techniques are used largely to assign economic value to non-market goods such as clean air and water, the provision of public open space, non-market healthcare, risk reduction policies, and the protection of cultural assets by asking people what value they attach to those goods or services. They describe the design and analysis of contingent valuation and choice modelling questionnaires and the resultant data. Issues of validity, reliability, aggregation, and reporting are examined and possible combinations of revealed and stated techniques are explored. Annotation c. Book News, Inc.,Portland, OR
