This paper investigates Value at Risk and Expected Shortfall for CAC 40, S&P 500, Wheat and Crude Oil indexes during the 2008 financial crisis. We show an underestimation of the risk of loss for the unconditional VaR models as compared with the conditional models. This underestimation is...

In practice, to calibrate the VaR, a normal approximation is often chosen for the unknown distribution of the yearly log returns of financial assets. This is usually justified by the...

Systematic and multifactor risk models are revisited via methods which were already successfully developed in signal processing and in automatic control. The results, which bypass the usual criticisms on those risk modeling, are illustrated by several successful computer experiments.

This article analyses the complementarity between various dimensions of corporate social responsibility (CSR) and financial performance. We hypothesise that the absence of consensus in the empirical literature on the CSR-financial performance relationship may be explained by the existence of...

This paper aims to study the contagion effects of the subprime financial crisis on the real economy of the USA. The contagion of this crisis is measured by increased linkages between markets after a shock has taken place (the stock market shocks, the interbank spread). The VAR model is utilized...
