Chicago Board Options Exchange (CBOE) volatility index (VIX) options. Our methodology is analytically tractable and yet … modeling the stochastic co-volatility factor can significantly improve the in-sample fitting results due to the improved …

general local-stochastic volatility model with zero correlation. We do this using the Freidlin-Wentzell theory of large …-time asymptotic behaviour for call options using Holder's inequality, and the implied volatility. This avoids the use of possibly non …, which is analysed at length in Busca et al. We also derive a series expansion for the implied volatility in the small …

then apply a similar analysis to a time-dependent Heston stochastic volatility model, and we show to construct a time …-dependent mean reversion and volatility-of-variance function, so as to be consistent with the observed variance swap curve and a pre … second moments of the integrated variance, and derive an approximation for the price of a volatility swap under the time …

volatility model, by developing efficient transform based pricing methods. This non-affine model gives prices of options on … realized variance which allow upward sloping implied volatility of variance smiles. Heston's (1993) model, the benchmark affine … stochastic volatility model, leads to downward sloping volatility of variance smiles - in disagreement with variance markets in …

This paper considers the problem of European option pricing in the presence of proportional transaction costs when the price of the underlying follows a jump diffusion process. Using an approach that is based on maximization of the expected utility of terminal wealth, we transform the option...

In this paper we consider a dense subclass of such models and develop analytically … Fourier transforms of vanilla and forward starting option prices as well as a formula for the slope of the implied volatility … volatility swaps and other volatility derivatives are given as a one-dimensional integral of an explicit function. Analytically …
