Abstract: We propose a novel time-changed Lévy LIBOR market model for the joint pricing of caps and swaptions. The time changes are split into three components. The first component allows us to match the volatility term structure, the second generates stochastic volatility, and the third one accommodates for stochastic skew. The model is parsimonious, yet flexible enough to accommodate the behavior of both caps and swaptions well. For the joint estimation we use a comprehensive dataset spanning the recent financial crisis. We find that, even during the recent financial crisis, neither market is as fragmented as suggested by the previous literature.
