Abstract: In this paper we examine the pricing of arbitrary credit derivatives with the Libor Market Model with Default Risk. We show, how to setup the Monte Carlo-Simulation efficiently and investigate the accuracy of closed-form solutions for Credit Default Swaps, Credit Default Swaptions and Constant Maturity Credit Default Swaps. In addition we derive a new closed-form solution for Credit Default Swaptions which allows for time-dependent volatility and arbitrary correlation structure of default intensities.
Keywords: LIBOR market model, credit risk, Credit Default Swaption, Constant Maturity Credit Default Swap.
