Abstract:
The double-bounded dichotomous choice contingent valuation format is thought to yield more precise estimates. Questions remain about it validity. The initial bid may represent information with which respondents update their willingness-to-pay. A Bayesian model of respondent decision making is estimated for two data sets. The results indicate updating or shifts in respondents willingness-to-pay between iterated valuations. Nonparametric testing of the welfare estimates reveals that the model incorporating updating yields different values from the standard model. The expected increases in the precision of the welfare losses are lost when updating occur.
