In this paper we are interested in inference based on heteroskedasticity consistent covariance matrix estimators, for which the appropriate bootstrap is a version of the wild bootstrap. Simulation results, obtained by a new very efficient methos, show that all wild bootstraps tests exhibit...

Nous etudions dans un modele a generations avec altruisme imparfait la distribution de la richesse de long terme ainsi que les inegalites sociales qu'elle engendre. Puis nous introduisons successivement dans le modele deux types de politique fiscale redistributive: une taxation des heritages et...

Risk a basic parameter of portfolio selection and its modelling involves some difficulties. Thus, more and more researchers try to find a solution to this problem proposing other measures than the classic ones used in portfolio selection. On the other hand, Multicriteria Decision Aid has known a...

The aim of this paper is to present a new value of a cooperative game for the case of limited communication between players. The communication system we consider may be represented by a simple graph, that is, only pairwise meetings can occur and some of them are not permitted. An associated game...

In this paper, we develop a Schumpeterian discrete-time model of endogeneous growth with an explicit market for the resource used for innovation-creating investment, and study its global dynamics. We show, among others, that the level of investment may fluctuate chaotically for a compact range...

A partir d'une description detaillee du deroulement concret des activites bord a quai, sur un terminal a conteneurs, des outils econometriques simples sont mis en oeuvre pour elucider les relations fonctionnelles entre les facteurs de production. La robustesse du modele de production propose est...
