). At the same time, however, it has been criticized for issues relating to backtesting. In particular, ES has been found … not to be elicitable which means that backtesting for ES is less straight-forward than, e.g., backtesting for VaR … the estimation and backtesting of ES, it can be considered a good risk measure. In particular, there is no sufficient …

Risk diversification is the basis of insurance and investment. It is thus crucial to study the effects that could limit it. One of them is the existence of systemic risk that affects all the policies at the same time. We introduce here a probabilistic approach to examine the consequences of its...

In this paper we study, using the sup LR test, the possibility of discrimination between two classes of models: the Markov switching models of Hamilton (1989) and the Threshold Auto-Regressive Models (TAR) of Lim and Tong (1980). This work is motivated by the fact that generally practicians use,...

Using non-parametric and parametric models, we show that the bivariate distribution of an Asian portfolio is not stable along all the period under study. We suggest several dynamic models to compute two market risk measures, the Value at Risk and the Expected Shortfall: the RiskMetrics...

Nous proposons dans cet article, à partir des approches de Taylor (2008) et de Gouriéroux et Jasiak (2008), d'agréger différents modèles de quantiles et d'expectiles afin d'obtenir une méthode plus robuste de calcul de la valeur-en-risque et de la perte conditionnelle maximale en...
