CBI-time-changed Lévy processes
Claudio Fontana, Alessandro Gnoatto, Guillaume Szulda
We introduce and study the class of CBI-time-changed Lévy processes (CBITCL), obtained by time-changing a Lévy process with respect to an integrated continuous-state branching proc…
CBI-time-changed Lévy processes for multi-currency modeling
Claudio Fontana, Alessandro Gnoatto, Guillaume Szulda
We develop a stochastic volatility framework for modeling multiple currencies based on CBI-time-changed Lévy processes. The proposed framework captures the typical risk characteris…
Multiple yield curve modelling with CBI processes
Claudio Fontana, Alessandro Gnoatto, Guillaume Szulda
We develop a modelling framework for multiple yield curves driven by continuous-state branching processes with immigration (CBI processes). Exploiting the self-exciting behavior of…
