(ré)Interpréter les réponses aux enquêtes d'évaluation contingente : du malentendu à l'analyse du compromis
Researchers still have difficulties to interpret answers from contingent valuation surveys. The usual theoretical framework, based on utilitarianism and welfare economics, fails for instance to provide satisfactory explanations for refusal to contingent questions, which can sometimes represent half of the sample of respondents. This framework is characterized by significant internal theoretical invalidities and should therefore be abandoned. Alternative analyses based on the concept of incommensurability do not provide a more pertinent interpretation framework. They attempt to show why some people refuse to answer but they do not explain the meaning of the positive answers collected. The hypothesis developed in this article is that these two ways of explanation fail because they are both based on the idea that people answering to willingness to pay questions do substitute between money and environmental goods. The idea developed here is that there is a misunderstanding between researchers and people interviewed: the researchers are the only ones to know this interpretation of substitution, while the people interviewed are concretely facing a payment vehicle that is more a compromise than a substitution.
