在Black and Cox的结构化方法框架下,运用偏微分方程(PDE)的方法,给出了随机利率基于Hull—White模型且信息不对称时的可违约公司债券的定价公式和信用利差公式,并进行了数值模拟。
This paper provides a method for valuing risky bonds with information dissymmetry by using Black and Cox's structural method. The price and the credit spread of defaultable bonds are derived by means of PDE. In addition, we have analyzed them with numerical examples.
