We demonstrate that increasing the risk surrounding the variance of future consumption generates a fourth-degree risk deterioration in future consumption, yielding an increase in its excess kurtosis. Its impact on the equilibrium risk premium is thus positive if only if the fourth derivative of the...

Classically, finite modified logarithmic Sobolev inequalities are used to deduce a differential inequality for the evolution of the relative entropy with respect to the invariant measure. We will check that these inequalities are ill-behaved with respect, on one hand, to the symmetrization...

The focus of this paper is the nonparametric estimation of the marginal effects (i.e. first partial derivatives) of an instrumental regression function ? defined by conditional moment restrictions that stem from a structural econometric model , and involve endogenous variables Y and Z and...

Malgré les développements et enseignements récents et actuels, des erreurs analytiques perdurent en évaluation de projets. Cinq méprises (ou absences de meilleures pratiques) omniprésentes résultent de ces erreurs : 1. l’utilisation du coût moyen pondéré du capital CMPC de l’entreprise pour évaluer...

Combining the results of a recent paper by Fleckinger-Hernández-de Thélin for a non cooperative 2 x 2 system with the method of PhD Thesis of M. H. Lécureux we compute the sign of the solutions of a n x n non-cooperative systems when the parameter varies near the lowest principal eigenvalue of the...

wo types of intrinsically motivated workers are considered: good workers care about the mission of an organization, whereas bad workers derive pleasure from destructive behavior. Compared to the case with only good workers, the mission‐oriented sector has to resort to higher monitoring to deal with...
