Value Transfer Method
Often, value transfer is used for screening in a benefit-cost analysis of project or policy alternatives.
Benefits transfer, or more generally value transfer refers to applying quantitative estimates of ecosystem service values from existing studies to another context. You take value estimates from a study site and apply them with adjustments to a policy site where time or resource constraints preclude the possibility of doing a primary valuation study. In the value transfer literature values have generally been understood to be monetary estimates of benefits or costs. Value transfer is not one specific method, but a continuum of approaches depending on the information available.
