The paper addresses the issue of rethinking the welfare state as a part of a broader national system of social protection (NSSP) and a mode of societal regulation. In order to overcome the theoretical limits of bottom-up comparative analysis of welfare states, one builds a structural model of...

L’objectif de cet article est d’étudier la capacité des mécanismes identitaires à générer une communauté de pratique. L’étude longitudinale d’un réseau de soin de chirurgiens dentistes montre que la construction identitaire associée à la négation collective des jeux de...

We evaluate the impact of three auction mechanisms – the Becker–DeGroot–Marschak (BDM) mechanism, the second-price auction (SPA), and the random nth-price auction (NPA) – in the measurement of private willingness-to-pay and willingness-to-accept for a pure public good. Our results show...

This paper explores the relationship between dynamic consistency and existing notions of unambiguous events for Choquet expected utility preferences. A decision maker is faced with an information structure represented by a filtration. We show that the decision maker’s preferences respect...

In this paper, we want to characterize the optimal health insurance contract with adverse selection and moral hazard. We assume that policyholders differ by the permanent health status loss and choose an unobservable preventive effort in order to reduce the probability of illness which is...

Since the seminal paper of Ghirardato, it is known that Fubini Theorem for non-additive measures can be available only for functions defined as “slice-comonotonic”. We give different assumptions that provide such Fubini Theorems in the framework of product σ-algebras.

L'objectif de l'intelligence stratégique est d'aider la connaissance et la compréhension de la situation stratégique. Nous établissons qu'en majorité la littérature sur l'intelligence stratégique propose une vision qui semble "rationnelle", mais qui de manière prévisible ne permet pas...

The standard literature on the value of life relies on Yaari’s (1965) model, which includes an implicit assumption of risk neutrality with respect to life duration. To overpass this limitation, we extend the theory to a simple variety of nonadditively separable preferences. The enlargement we...

À la suite d’un Livre Vert consacré à l’esprit d’entreprise, la Commission européenne s’est récemment inquiétée du déficit d’entrepreneurs de l’Europe par rapport aux États-Unis. Cet article présente un modèle de commerce international avec incertitude qui étudie les...

Peter P. Wakker has forcefully shown the importance for decision theory of a condition that he called “Cardinal Coordinate Independence” (CCI). Indeed, when the outcome space is rich, he proved that, for continuous weak orders, this condition fully characterizes the Subjective Expected...
