Abstract

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.

Notes

  1. Throughout this paper we use the nomenclature defined by Carson and Louviere (2011) to describe stated preference typologies.

  2. Adamowicz et al. (2011) refer to Format A and Format B as contingent valuation and choice experiment, respectively.

  3. Results from the ordering-effect tests and from models estimated with yea-sayers are available in the supplementary appendix. Models estimated with yea-sayers produce higher WTP values but are similar to models without yea-sayers with regards to temporal stability.

  4. We also assess possible differences in scale using a generalized mixed logit model (Fiebig et al. 2010), which is an extension of the MLM that allows for respondent-specific scale heterogeneity. We model scale as a function of dataset indicators. Findings show significant heterogeneity in scale but no systematic differences across datasets.

  5. In addition, we estimate a CLM where parameters for all four datasets are determined simultaneously and have been adjusted for scale differences. This approach allows for the direct comparison of parameters across all datasets. Results, reported in “Appendix B”, indicate no significant differences in parameters between the two Format A datasets or the two Format B datasets. There are, however, differences across elicitation formats, lending further support to the use of separate Format A and Format B models.

  6. Inflation-adjusted WTP values can be calculated either by adjusting Bill levels ex-ante of model estimation or by adjusting WTP ex-post of the estimation. Brouwer and Bateman (2005) and Metcalfe and Baker (2015) use the former procedure while Hensher et al. (2012) suggest the latter approach better preserves the behavioral tradeoffs intrinsic to each time period. We find that the two methods yield nearly identical WTP values.

  7. The existence of two classes, with one preferring the status quo and the other the policy-proposed alternative, has been noted in the context of other low-probability high-consequence events (McClelland et al. 1993; Botzen and van den Bergh 2012). McClelland et al. (1993) reason that bimodal preferences will arise if some respondents focus on the high-consequence component while others focus on the low-probability of the event.
