Contingent-valuation estimates for white-water boating passengers are compared with Likert ratings by river guides. The approach involves asking whether passengers and their guides ordinally rank alternative flows the same. The National Oceanic and Atmospheric Administration's Contingent...

In an excellent article from a recent issue of this journal, Sellar, Stoll and Chavas (1985) make a technical error which causes them to misstate their closed-ended estimates of willingness to pay. Truncation of the estimated cummulative distribution function must we made explicit in compution...

In a recent study, Whitehead (2002) proposes incentive-incompatibility and starting-point-bias tests for iterative willingness-to-pay questions. We show that if restrictions associated with the nature of starting-point bias are not imposed on the ...

Two methods for calibrating discrete choice contingent valuation responses – the dichotomous choice with followup certainty question method of Champ et al. (1997) and the multiple bounded method of Welsh and Poe (1998) – are evaluated using data from a field validity comparison of...

A mail survey was administered to a panel of Colorado consumers to obtain estimates of willingness to pay (WTP) for preserving Union Park. Detailed socioeconomic data for all surveyed individuals was available a priori. We develop and employ the multiple-bounded probit with selection (MBPS)...

Two methods for calibrating discrete choice contingent valuation responses—the dichotomous choice with follow-up certainty question method of and the multiple-bounded method of —are evaluated using data from a field validity comparison of hypothetical and actual participation decisions in a...

Dichotomous choice contingent valuation surveys frequently elicit multiple values in a single questionnaire. If individual responses are correlated across scenarios, the standard approach of estimating willingness to pay (WTP) functions independently for each scenario may result in biased...
