We define an equity-interest rate hybrid model in which the equity part is driven by the Heston stochastic volatility … [Hes93], and the interest rate (IR) is generated by the displaced-diffusion stochastic volatility Libor Market Model [AA02 …]. We assume a non-zero correlation between the main processes. By an appropriate change of measure the dimension of the …

We propose a new derivation of the Heath–Jarrow–Morton risk-neutral drift restriction that takes into account nonzero instantaneous correlations between factors. The result allows avoiding the orthogonalization of factors and provides an approach by which interest rate derivatives can be...

We introduce a refined tree method to compute option prices using the stochastic volatility model of Heston. In a first … marginal tree moments up to order two against the Heston model ones. The correlation between the driving Brownian motions is … the match between tree and model correlation. In some nodes, we are even able to further match moments of higher order …
