Researchers are increasingly considering benefit transfer approaches that allow welfare measures to be adjusted for characteristics of the policy context. The validity and reliability of such adjustments, however, depends on the presence of systematic variation in underlying WTP This paper describes a meta-analysis conducted to identify systematic components of WTP for aquatic resource improvements. Model results reveal systematic patterns in WTP unapparent from stated preference models considered in isolation, and suggest that observable attributes account for a substantial proportion of the variance in WTP estimates across studies. The analysis also exposes challenges faced in development, estimation, and interpretation of meta-models for benefit transfer and welfare guidance. These challenges remain salient even in cases where the statistical performance of meta-models is satisfactory.
