Hazard rate for credit risk and hedging defaultable contingent claims


  • Christophette Blanchet-Scalliet


  • Monique Jeanblanc



We provide a concise exposition of theoretical results that appear in modeling default time as a random time, we study in details the invariance martingale property and we establish a representation theorem which leads, in a complete market setting, to the hedging portfolio of a vulnerable claim. Our main result is that, to hedge a defaultable claim one has to invest the value of this contingent claim in the defaultable zero-coupon. Copyright Springer-Verlag Berlin/Heidelberg 2004
