We propose a consistent and computationally efficient 2-step methodology for the estimation of multidimensional non-Gaussian asset models built using Lévy processes. The proposed framework allows for dependence between assets and different tail-behaviors and jump structures for each asset. Our...

This paper discusses a class of methodological issues that frequently arise in the risk management systems such as PFE and CVA engines. Simplified methodology and shortcuts come at a price, sometimes a steep one. To account for model deficiencies and disconnect between the calibration and the...
