This paper proposes a two-factor hazard rate model, inclosd form, to price risky debt. The likelihood ofdefault is captured by the firm's non-interestsensitive assets and default-free interest rates.The distinguishing features of the model arethreefold. First, the impact of capital structurechanges on credit spreads can be analyzed. Second,the model allows stochastic interest rates to impactcurrent asset values as well as their evolution.Finally, the proposed model is in closed fom,enabling us to undertake comparative staticsanalysis, compute parameter deltas of the model,calibrate empirical credit spreads, and determinehedge positions. Credit spreads generated by ourmodel are consistent with empiricalobservations.
