Time series models for credit default swap premiums
This paper analyzes the theoretical properties and statistical behavior of credit default swap (CDS) premiums over time.
Cutting edge intro: Righting wrong-way risk
Models that describe wrong-way risk should move away from simplistic copula models, critics say.

Cutting edge intro: CDOs and the risk of risk aversion
New analysis shows CDOs can withstand high levels of correlation – what they can’t cope with, though, is a sudden change in risk appetite

Perturbed Gaussian copula: introducing the skew effect in co-dependence
Gaussian copula models are often used in the industry when single-asset information is quoted but little is known about their joint relation. These models may arise from correlated stochastic Brownian processes with deterministic volatility and…
