Valuation of default-sensitive claims under imperfect information


Coculescu, Delia; Geman, Hélyette; Jeanblanc, Monique (2008). Valuation of default-sensitive claims under imperfect information. Finance and Stochastics, 12(2):195-218.

Abstract

We propose a valuation method for financial assets subject to default risk, where investors cannot observe the state variable triggering the default but observe a correlated price process. The model is sufficiently general to encompass a large class of structural models and can be seen as a generalization of the model of Duffie and Lando (Econometrica 69:633–664, [2001]). In this setting we prove that the default time is totally inaccessible in the market’s filtration and derive the conditional default probabilities and the intensity process. Finally, we provide pricing formulas for default-sensitive claims and illustrate in particular examples the shapes of the credit spreads.
