Abstract: Consider a defaultable firm which issues corporate bond to raise capital. The firm’s credit quality is assumed to be affected by the cycle of macroeconomy. The investors of the bond could buy credit default swap (CDS) against the risk of default on the financial market. We propose a new structural form credit risk model being used for pricing the bond and the CDS. In the proposed model, the market value of the firm is assumed to follow a geometric jump diffusion process with macroeconomic factor. We investigate the influence of the macroeconomy on the probability of default, the price of the bond, and the CDS. Closed form results used to derive the numerical solutions for them are obtained when the common distribution of jumps is double exponential distribution. The numerical results exhibit some behaviors for the probability of default, the price of the bond, the bond yield spread and the CDS, respectively.
