VALIDATION OF BENEFIT-TRANSFER FUNCTIONS

Impact/Purpose:

1. Investigate criterion validity of benefit-transfer equations using simulated data. 2. Investigate convergent validity of benefit-transfer functions using “off-the-shelf” valuation data. 3. Investigate the sensitivity of the validity findings to applications of in situ versus marginal-effect use values. 4. Investigate the robustness of the convergent validity findings to freshwater fishing and coastal beach use applications. 5. Investigate whether supplementing existing valuation study data with GIS data enhances benefit-transfer function validity. Hypotheses tested will include the null hypotheses that preference parameters recovered from the estimated benefit-transfer functions are not significantly different from those defined for the simulated policy site (Objective 1) and from those estimated in original studies at policy sites (Objective 2). The null hypotheses tested will also include that there is no difference between benefit transfer predictions and known/estimated values at the policy sites. These tests will be replicated for Objectives (3), (4) and (5) to test the sensitivity of the validity investigations to situations typically faced by policy makers.

Description:

1. Identification of benefit-transfer functions that are the most credible. 2. Identification of benefit-transfer issues that are related to transfer method and those related to data limitations. 3. Clarification of issues that need further research to enhance the validity of benefit-transfer functions. 4. Identification of where original research on the values of freshwater fishing and coastal beach is needed to support benefit transfers. 5. More accurate measurement of benefits and costs by EPA and other federal and state agencies.
