Abstract

Dans cet article, nous formalisons deux critères de décisions qui tentent de rendre compte de deux logiques différentes d'interprétation du Principe de précaution. Le premier critère correspond à la maximisation du minimum de l'espérance d'utilité alors que le second critère correspond à la minimisation du maximum de l'espérance de regret. Les deux critères de décisions sont appliqués à un problème économique où l'incertitude est mesurée par une famille de probabilités. Nous montrons qu'il existe un intervalle de probabilités sur lequel les choix relatifs aux deux critères divergent. Plus particulièrement, nous montrons que sur cet intervalle, le second critère à la différence du premier, conduit toujours à retenir la décision la plus précautionneuse, les décisions étant identiques sur les autres intervalles.
