Operational risk measurement beyond the loss distribution approach: an exposure-based methodology
In this paper, the authors present an alternative quantification technique, so-called exposure-based operational risk (EBOR) models, which aim to replace historical severity curves by measures of current exposures and use event frequencies based on…

Better risk and performance estimates with factor-model Monte Carlo
This paper presents a solution to a common problem in asset and portfolio risk, when a manager has such a short history of asset returns that risk and performance measure estimates are unreliable.
Estimation of risk measures for large credit portfolios
In this paper, saddle point techniques are used in the computation of risk measures for large mark-to-market credit portfolios with stochastic recovery and correlation between obligors depending on the state of the economy.
