In this paper, we propose a general framework for the valuation of options in stochas-tic local volatility (SLV) models … as special cases. Standard stochastic volatility models, such as Heston, Hull-White, Scott, Stein-Stein, α …-Hypergeometric, 3/2, 4/2, mean-reverting, and Jacobi stochastic volatility models, also fall within this general framework. We propose a …

This paper addresses several theoretical and practical issues in option pricing and implied volatility calibration in a … volatility term structure when the Hurst exponent is not 0.5, and also that one-year implied volatility is independent of Hurst … exponent and equivalent to fractional volatility. Building on these observations, we introduce a novel 8-parameter fractional …

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...

We derive multidimensional transforms which allow us to construct … efficient path-independent lattices for virtually all low-dimensional stochastic volatility models given in the literature … including one volatility factor-based stochastic volatility (SV) models, two volatility factors-based SV models, stochastic …

In this dissertation we price European and American vanilla and barrier options assuming that the underlying follows the variance gamma process. We solve numerically the problem implementing a finite difference algorithm and we present numerical experiments on the option pricing. This...

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 …
