In line with regulations and common risk management practice, the credit risk of a portfolio is managed via its … computations to exposure computations, firms find it expedient to compute these exposures under the risk neutral measure.Here we … show that exposures computed under the risk neutral measure are essentially arbitrary. They depend on the choice of …

When measuring market risk, credit institutions and Alternative Investment Fund Managers may deviate from equally … weighting historical data in their Value-at-Risk calculation and instead use an exponential time series weighting. The use of … exponential weighting in the Value-at-Risk calculation is very popular because it takes into account changes in market volatility …

Choosing a proper external risk measure is of great regulatory importance, as exemplified in the Basel II and Basel III … Accord which use Value-at-Risk (VaR) with scenario analysis as the risk measures for setting capital requirements. We argue a … good external risk measure should be robust with respect to model misspecification and small changes in the data. A new …

This paper evaluates the model risk of models used for forecasting systemic and market risk.

Finally, particular conclusions on the underlying reasons for the high model risk and …
