摘要：
We evaluate the temporal stability of willingness-to-pay values obtained from two identical stated-preference surveys undertaken in 2004 and 2012. The surveys employ two discrete-choice elicitation formats to value reductions in two health endpoints related to tap water consumption, and are explicitly designed to make direct comparisons between formats. We find no significant differences in real willingness-to-pay between the two surveys for either format-a result that is robust to the structure of heterogeneity used to model respondent preferences. Findings lend support, at least within the context of tap water quality, to the temporal transfer of nonmarket benefits over extended time periods.
