WTP Revelation: Open-Ended or Dichotomous-Choice Questions? An Application to the
Biodiversity of the Garonne River Forests
by Caroline Gauthier
This paper offers a contingent valuation of individuals' willingness to pay for preservation of biodiversity. It is the first study of its kind to be carried out in France. It has been conducted according to the rules proposed by the NOAA Panel, with the exception of the revelation method. The sample of 402 individuals interviewed was divided into those who declared their WTP on the basis of an open-ended question and those who declared it on the basis of a dichotomous-choice question. The two formats were then compared. The paper offers two tests demonstrating that the WTPs calculated by each method are not significantly different. Although the NOAA Panel recommends use of the closed format, this paper shows that use of the open-ended question is equally relevant and less expensive given the level of information required.
