Validity Tests of Benefit Transfer – Are We Performing the Wrong Tests?

Environmental & Resource Economics, 2005, vol. 30, issue 3, 279-286

Abstract: The validity of environmental benefit transfer has been tested on numerous occasions assuming classical null hypothesis of equality. We argue against this assumption on the basis of theory, which clearly indicates that environmental benefits should be assumed to vary from context to context. We suggest the use of equivalence testing as a more appropriate and a clear compliment to the shortcomings of classical tests. Equivalence tests test the null hypothesis of difference between the original and transferred value estimates. Equivalence tests also combine the concepts of statistical significance and policy significance into one test, by defining an acceptable transfer error prior to the validity test. The results of a published study on validity of benefit transfer are reversed when subjected to an equivalence test. Copyright Springer 2005
