STOCHASTIC VOLATILITY

International Journal of Theoretical and Applied Finance, 2002
Hull and White [1] have priced a European call option for the case in which the volatility of the underlying asset is a lognormally distributed random variable. They have obtained their formula under the assumption of uncorrelated innovations in security price and volatility.

Stochastic Volatility of Volatility and Variance Risk Premia

SSRN Electronic Journal, 2011
This article introduces a new class of stochastic volatility models which allows for stochastic volatility of volatility (SVV): Volatility modulated non-Gaussian Ornstein--Uhlenbeck (VMOU) processes. Various probabilistic properties of (integrated) VMOU processes are presented.

Stochastic volatility demand systems [PDF]

open access: possibleEconometric Reviews, 2015
We address the estimation of stochastic volatility demand systems. In particular, we relax the homoscedasticity assumption and instead assume that the covariance matrix of the errors of demand systems is time-varying. Since most economic and financial time series are nonlinear, we achieve superior modeling using parametric nonlinear demand systems in ...

Stochastic Volatility Models

2008
Stochastic volatility (SV) is the main concept used in the fields of financial economics and mathematical finance to deal with the endemic time-varying volatility and codependence found in financial markets. Such dependence has been known for a long time; early commentators include Mandelbrot (1963) and Officer (1973). It was also clear to the founding

Complete Models with Stochastic Volatility

Mathematical Finance, 1998
The paper proposes an original class of models for the continuous‐time price process of a financial security with nonconstant volatility. The idea is to define instantaneous volatility in terms of exponentially weighted moments of historic log‐price. The instantaneous volatility is therefore driven by the same stochastic factors as the price process ...

Asset Pricing with Stochastic Volatility

Applied Mathematics & Optimization, 2001
Let a market consist of a stock \(S_t\) and a bond \(B_t\) governed by the equations \[ dS_t= a(t,S_t)S_tdt+ \sigma_tS_tdw_t \] and \[ dB_t=r_t B_tdt,\;B_0=1, \] where \(r_t\) is a bounded, nonnegative, progressively measurable interest rate process. The volatility \(\sigma_t\) is supposed to be random and satisfying on another stochastic differential ...

IMPLIED AND LOCAL VOLATILITIES UNDER STOCHASTIC VOLATILITY

International Journal of Theoretical and Applied Finance, 2001
For asset prices that follow stochastic-volatility diffusions, we use asymptotic methods to investigate the behavior of the local volatilities and Black–Scholes volatilities implied by option prices, and to relate this behavior to the parameters of the stochastic volatility process.

Discrete Stochastic Autoregressive Volatility

SSRN Electronic Journal, 2013
Abstract We use Markov chain methods to develop a flexible class of discrete stochastic autoregressive volatility (DSARV) models. Our approach to formulating the models is straightforward, and readily accommodates features such as volatility asymmetry and time-varying volatility persistence.

Stochastic Volatility

2005
Abstract Neil Shephard has brought together a set of classic and central papers that have contributed to our understanding of financial volatility. They cover stocks, bonds and currencies and range from 1973 up to 2001. Shephard, a leading researcher in the field, provides a substantial introduction in which he discusses all major ...
