Les prestations de services professionnels sont par définition intangibles et génèrent en conséquence une perception de risque et d’incertitude chez le client. Pour y remédier, la confiance a été identifiée comme étant la solution idéale. Or, l’idée dominante est que le...

"The authors study the effect of financial crises on trade credit in a sample of 890 firms in six emerging economies. They find that although provision of trade credit increases right after the crisis, it consequently collapses in the following months and years. The authors observe that firms...

In general, the properties of the conditional distribution of multiple period returns do not follow easily from the one-period data generating process. This renders computation of Value-at-Risk and Expected Shortfall for multiple period returns a non-trivial task. In this paper we consider some...

In this note it is argued that the estimation error in Value-at-Risk predictors gives rise to underestimation of portfolio risk. We propose a simple correction and find in an empirical illustration that it is economically relevant.

In the estimation of risk measures such as Value at Risk and Expected shortfall relatively short estimation windows are typically used rendering the estimation error a possibly non-negligible component. In this paper we build upon previous results for the Value at Risk and discuss how the...
