Stochastic volatility models have grown in popularity in the past decade or two. However, for many stochastic … volatility models, the functional form of volatility along with the description of the diffusion process for volatility have been … improves and that a more general specification for the stock price and volatility processes may be necessary.

We introduce a new method to price American-style options on underlying investments governed by stochastic volatility … (SV) models. The method does not require the volatility process to be observed. Instead, it exploits the fact that the … distributions of volatility, given observed data. By constructing statistics summarizing information about these conditional …

The stochastic-alpha-beta-rho (SABR) model introduced by Hagan et al. (2002) provides a popular vehicle to model the implied volatilities in the interest rate and foreign exchange markets. To exclude arbitrage opportunities, we need to specify an absorbing boundary at zero for this model, which...

We consider the joint SPX-VIX calibration within a general class of Gaussian polynomial volatility models in which the … volatility of the SPX is assumed to be a polynomial function of a Gaussian Volterra process defined as a stochastic convolution … between a kernel and a Brownian motion. By performing joint calibration to daily SPX-VIX implied volatility surface data …
