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 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...

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,...

(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...

The estimation of multivariate GARCH models remains a challenging task, even in modern computer environments. This manuscript shows how Independent Component Analysiscan be used to estimate the Generalized Orthogonal GARCH model in a fraction of the time otherwise required. The proposed method...
