报告地点:数学楼第二报告厅

报告摘要:

In this talk, we explain how the default intensity of a defaultable firm can be defined as the intensity of a point process. The default time of the firm can be thus defined as the first jump time of a point process.  The default dependence is described by the dependence among the default intensity processes of the defaultable firms. As an example, we present a reduced form credit risk model in which the default dependence is described by the common shock and regime switching and correspondingly establish the pricing formula for the basket CDS spreads.
