摘要：One way of assessing the validity of results generated through the application ofthe Contingent Valuation Method (CVM) is through the analysis of responsesensitivity to factors expected to have an in￡uence. Scope testing involvespresenting at least two alternative impact scenarios to population sub-samples andtesting for di.erences between the estimates generated. Most applications of theCVM in Australia have not involved scope testing and those that have yieldedmixed results. These studies are reviewed. The results of scope sensitivity and othervalidity tests are presented for a study aimed at estimating the value ofenvironmental damage caused by dryland salinity in the Upper South East ofSouth Australia.
