Model risk as part of the operational risk is a serious problem for financial institutions. As the pricing of derivatives as well as the computation of the market or credit risk of an institution depend on statistical models the application of a wrong model can lead to a serious over- or...

We provide an economic valuation of the riskiness of risk models by directly measuring the impact of model risks (specification and estimation risks) on VaR estimates. We find that integrating the model risk into the VaR computations implies a substantial minimum correction of the order of...

The experience from the global financial crisis has raised serious concerns about the accuracy of standard risk measures as tools for the quantification of extreme downward risks. A key reason for this is that risk measures are subject to a model risk due, e.g. to specification and estimation...

This paper investigates the inter-temporal relationship between banking profitability, competition and risk of a sample of Chinese commercial banks by employing several profitability and risk indicators and using Seemingly Unrelated Regression (SUR) under a panel data framework over 2003-2009....

In the paper an econometric method of rating scales mapping is suggested. The method is based on the setting up ordered choice models for the ratings and mapping the correspondent latent variables («continuous ratings») with a monotone function. The method takes into account bank’s financial...

The objective of this paper is to provide a complete framework to aggregate different quantile and expectile models for obtaining more diversified Value-at-Risk and Expected Shortfall measures, by applying the diversification principle to model risk. Following Taylor (2008) and Gouriéroux and...
