This paper provides regime-switching stochastic volatility extensions of the LIBOR market model. First, the … instantaneous forward LIBOR volatility is modulated by a continuous time homogeneous Markov chain. In a second parameterization, the … volatility is modelled by a square root process with a regime-switching reference level. We obtain analytical solutions for the …

We derive a closed-form asymptotic expansion formula for option implied volatility under a two-factor jump …-diffusion stochastic volatility model when time-to-maturity is small. Based on numerical experiments we describe the range of time … free of the unobserved spot volatility. Therefore, the model can be calibrated on option data pooled across different …

In this paper, we extend the earlier results of Jeanblanc and Valchev (2003) in the single name case to the case of multiple defaults of the issuers in a concentrated industry or homo- geneous bond market. We provide solutions for the pairwise default correlations and credit spreads in an...
