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...

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...

We create an analytical structure that reveals the long-run risk-return relationship for nonlinear continuous-time Markov environments. We do so by studying an eigenvalue problem associated with a positive eigenfunction for a conveniently chosen family of valuation operators. The members of this...

Sorting models consist in assigning alternatives evaluated on several criteria to ordered categories. To implement such models it is necessary to set the values of the preference parameters used in the model. Rather than fixing the values of these parameters directly, a usual approach is to...

S. Kusuoka [K 01, Theorem 4] gave an interesting dual characterizationof law invariant coherent risk measures, satisfying the Fatou property.The latter property was introduced by F. Delbaen [D 02]. In thepresent note we extend Kusuoka's characterization in two directions, thefirst one being...

L’IASB poursuit son développement de normes visant à évaluer la quasi-totalité des instruments financiers à leur juste valeur. Le résultat net, le résultat étendu et le « Full Fair Value Income » représentent la performance et le risque des entreprises de manière très différente,...

Despite a large body of literature on the topic, empirical tests of real option models are scarce. The lack of data offers an initial explanation for this. However other intrinsic reasons could well explain why real options are difficult to test on large-scale studies. We show that the use of...
