Title: | Independence and variational bewley preferences: a note |
Author: | Bastianello, Lorenzo Faro, José Heleno Teles, Flávia |
Publication Date: | 2020 |
Original Abstract: | This note studies some alternatives and weak versions of the Independence axiom in a decision theoretic framework under uncertainty. We propose a characterization of this axiom using a property called Weight Independence. Moreover we study how the Independence axiom is related with the Variational Bewley model of Faro [2015]. We show that Variational Bewley preferences satisfy a weaker form of independence called Independence for Constant Weights. This topic gives us the opportunity to discuss the pioneeristic contributions of David Schmeidler on the weakening of the Independence axiom. |

Abstract: | Dans cet article nous étudions l’axiome d’indépendance dans un contexte de prise de décision dans l’incertain. Nous proposons une caractérisation de cet axiome qui utilise une propriété que nous appelons Weight Independence. De plus, nous étudions la relation entre l’axiome d’indépendance et le modèle de préférences variationnelles à la Bewley de Faro [2015]. Nous montrons que ces préférences satisfont une forme faible d’indépendance que nous appelons Independence for Constant Weights. Ce sujet nous donne l’opportunité d’examiner les contributions exceptionnelles de David Schmeidler en théorie de la décision pour ce qui concerne l’affaiblissement de l’axiome d’indépendance. |
