CDO建模中的不可能三重奏
The Impossible Trio in CDO Modeling
摘要:
我们发现,随机恢复总是导致违反直觉的行为,在CDO份额的风险措施-即,连续性违约和积极的信用利差风险不能同时确保。然后,我们提出了一个简单的恢复方差正则化方法来控制负信用利差风险的大小,同时保持违约的连续性。
英文摘要:
We show that stochastic recovery always leads to counter-intuitive behaviors in the risk measures of a CDO tranche - namely, continuity on default and positive credit spread risk cannot be ensured simultaneously. We then propose a simple recovery variance regularization method to control the magnitude of negative credit spread risk while preserving the continuity on default.
