Abstract

Relying on the paper of Due and Lando "Term structures of credit spreads with incomplete accounting information", based on information asymmetry in credit risk, we propose a discretized approach. We model the logarithm Z of the firm asset value process V as a Markov chain. The debtholders do not have perfect information on the actual value of the firm; they receive only a discrete noisy stream of reports Y . We study the pair {Z, Y }. Then, letting the increments go to zero, we compute the intensity of the default time. We compare our result with the result of Duffie and Lando (2001) in the Brownian case.
