between stock returns and idiosyncratic return volatility at the firm level. By allowing for the volatility of the underlying … idiosyncratic choice variables to exhibit independent switches between a high and low volatility regime, we show that the options …' constant expected returns are composed of (i) a state dependent drift term that relates positively with the volatility regime …

stochastically correlated default intensities, or multivariate dynamic portfolio choice with volatility and correlation jumps. We … implied volatility skew term structures that are largely unrelated to the level and composition of the spot volatility. This … options. Second, we find that volatility and correlation jumps can imply an economically relevant intertemporal hedging demand …

stochastic volatility models with jumps. 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 …

options under low-dimensional stochastic volatility models. 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 …

We develop an asymptotic expansion technique for pricing timer options under general stochastic volatility models … around small volatility of variance. Closed-form approximation formulas have been obtained for the Heston model and the 3 …
