model with stochastic interest rate and stochastic dividend yield. In particular, our modelling framework consists of a … stochastic interest rate driven by Hull-White (HW) or Cox-Ingersoll-Ross (CIR) processes and a stochastic dividend yield, also … driven by HW or CIR processes, which extends the framework of [Ros20] by incorporating the stochastic dividend yield and …

We present a stochastic-volatility, short rate term structure model, which extends the classic multi-factor Hull-White model. This model is designed to fit the swaption implied volatility cube and to incorporate the two-curve modeling paradigm. The model exhibits non-Gaussian forward swap rates...

This paper introduces a new jump diffusion process where the occurrence and the size of past jumps have an impact on both the instantaneous and the long term propensities of observing a jump instantaneously. Here, the intensity of jump arrival is a multifactor self-excited process whereas the...

By exploiting the flexibility of the Wishart process, we propose an application of this framework to the pricing of Chicago Board Options Exchange (CBOE) volatility index (VIX) options. Our methodology is analytically tractable and yet flexible enough to efficiently price CBOE VIX options. In...
