摘要翻译：
本文提出了一个二维结构框架来评估信用违约互换和存在违约传染的公司债券。将相关企业的价值建模为具有指数违约障碍的相关几何布朗运动，得到了信用违约互换利差和企业债券收益率的解析公式。信用依赖结构既受长期相关结构的影响，也受违约传染的可能性的影响。这样，该模型就能够使用真实的输入参数值来生成各种不同的信用利差期限结构形状。

英文摘要：
This paper develops a two-dimensional structural framework for valuing credit default swaps and corporate bonds in the presence of default contagion. Modelling the values of related firms as correlated geometric Brownian motions with exponential default barriers, analytical formulae are obtained for both credit default swap spreads and corporate bond yields. The credit dependence structure is influenced by both a longer-term correlation structure as well as by the possibility of default contagion. In this way, the model is able to generate a diverse range of shapes for the term structure of credit spreads using realistic values for input parameters.
