Abstract

Au cours d'une expérimentation, les auteurs ont étudié l'impact d'une nouvelle information concernant la sécurité alimentaire sur le consentement à payer des individus pour des produits alimentaires. Les prix ont été révélés à travers deux procédures d'enchères : soit des enchères au second prix, soit la procédure de Becker-DeGroot-Marschak. La révélation de ces offres s'est faite en trois étapes. Dans l'étape 1, les offres individuelles ont été effectuées sans aucune information. Dans l'étape 2, une information concernant les impacts sur la santé a été donnée. L'étape 3 a été caractérisée par la mise à disposition de nouveaux produits certifiés ; les individus ont alors pu faire des offres pour des produits certifiés et non certifiés. L'introduction de produits certifiés a entraîné une révision asymétrique des offres initiales : les offres pour les produits non certifiés ont été revues à la baisse mais les offres pour les produits certifiés sont restées égales aux offres initiales.
