报告摘要：

In thistalk, 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 canbe thus defined as the first jump time of a point process. The default dependence is described by the dependence among the default intensity processesof the defaultable firms. As an example, we present a reduced form credit riskmodel in which the default dependence is described by the common shock andregime switching and correspondingly establish the pricing formula for thebasket CDS spreads.
