摘要

本文提出、估计和测试了一个信用违约互换(CDS)定价模型,该模型将公司的违约强度与其观察到的股票价格联系起来。定价模型需要有限差分数值解。尽管如此,拟极大似然参数估计仍然是可行的。来自大公司样本的证据证实了公司股价与违约强度之间联系的有效性。

Credit default swap rates and stock prices
This article presents, estimates and tests a credit default swap (CDS) pricing model, which links a firm's default intensity to its observed stock price. The pricing model requires finite difference numerical solutions. In spite of this quasi-maximum likelihood parameter estimation is still feasible. Evidence from a sample of large corporations confirms the validity of the link between the firm's stock price and default intensity.
