In this paper, we characterize explicitly the first derivative of the Value at Risk and the Expected Shortfall with respect to portfolio allocation when netting between positions exists. As a particular case, we examine a simple Gaussian example in order to illustrate the impact of netting...

We study a test statistic based on the integrated squared difference between a kernel estimator of the copula density and a kernel smoothed estimator of the parametric copula density. We show for fixed smoothing parameters that the test is consistent and that the asymptotic properties are driven...

We consider a nonparametric method to estimate copulas, i.e. functions linking joint distributions to their univariate margins. We derive the asymptotic properties of kernel estimators of copulas and their derivatives in the context of a multivariate stationary process satisfactory strong mixing...

(VF)L'objet de cette recherche est de tenter d’expliquer les systèmes de décision et de contrôle lors des projets d’investissement. Pour cela, cette recherche met en évidence le rôle de l'architecture organisationnelle (répartition des droits sur la gestion de décision et sur le...

(VF)Plusieurs théoriciens et praticiens montrent que l’évaluation semble jouer un rôle relativement secondaire dans le processus d’investissement dans la mesure où elle intervient à titre de contrôle ex ante lors d'une phase de ratification. De ce fait, si on admet que l'efficience de...

Within the theoretical framework of organizational architecture, this paper attempts to explain the decentralization of investment decision. To do so, it highlights the role of the allocation of decision rights and control as a factor explaining the effectiveness of investment management. Thus,...

n this paper we analyse recovery rates on defaulted bonds using the Standard and Poors / PMD database for the years 1981-1999. Due to the specific nature of the data (observations lie within 0 and 1), we must rely on nonstandard econometric techniques. The recovery rate density is estimated...

The Basel Committee on Banking Supervision ("the Committee") released a consultative document that included a regulatory capital charge for operational risk. Since the release of the document, the complexity of the concept of "operational risk" has led to vigorous and recurring discussions. We...
