We show a substantive problem exists with the widely-used ratio of coefficients approach to
calculating willingness to pay (WTP) from discrete choice models. The correctly calculated …

Our original article proposed that the two yes–no willingness-to-pay (WTP) responses
produced by this survey format should be viewed as a pair of jointly distributed (correlated) …

The contingent valuation method estimates individuals' willingness to pay (WTP) for non‐

This paper introduces fully flexible (semi-nonparametric) methods for calculating willingness
to pay (WTP) bounded between zero and the respondent's income for dichotomous choice …

In models with unobserved taste heterogeneity, distributional assumptions can be placed in
two ways:(1) by specifying the distribution of coefficients in the utility function and deriving …

Correction for hypothetical bias using follow up certainty questions often takes one of two
forms:(1) two options,“definitely sure” and “probably sure”, or (2) a 10-point scale with 10 …

Standard procedures for extractingwillingness-to-pay (WTP) from dichotomouschoice CV
questionnaires rely heavily uponparametric assumptions regarding thedistribution and form …

Traditional referendum models of contingent valuation with linear utility functions and
