Asymptotic Analysis for Stochastic Volatility: Edgeworth expansion
نویسنده
چکیده
The validity of an approximation formula for European option prices under a general stochastic volatility model is proved in the light of the Edgeworth expansion for ergodic diffusions. The asymptotic expansion is around the Black-Scholes price and is uniform in bounded payoff functions. The result provides a validation of an existing singular perturbation expansion formula for the fast mean reverting stochastic volatility model.

The Asymptotic Expansion Formula of Implied Volatility for Dynamic SABR Model and FX Hybrid Model
The author considers SABR (stochastic-αβρ) model which is a two factor stochastic volatility model and give an asymptotic expansion formula of implied volatilities for this model. His approach is based on infinite dimensional analysis on the Malliavin calculus and large deviation. Furthermore, he applies the approach to a foreign exchange model where interest rates and the FX volatilities are s...
متن کاملAn Asymptotic Expansion with Push-Down of Malliavin Weights
This paper derives asymptotic expansion formulas for option prices and implied volatilities as well as the density of the underlying asset price in multi-dimensional stochastic volatility models. In particular, the integration-byparts formula in Malliavin calculus and the push-down of Malliavin weights are effectively applied. We provide an expansion formula for generalized Wiener functionals a...
متن کاملOn the Singular Limit of Solutions to the Cox-Ingersoll-Ross Interest Rate Model with Stochastic Volatility
In this paper we are interested in term structure models for pricing zero coupon bonds under rapidly oscillating stochastic volatility. We analyze solutions to the generalized Cox–Ingersoll-Ross two factors model describing clustering of interest rate volatilities. The main goal is to derive an asymptotic expansion of the bond price with respect to a singular parameter representing the fast sca...
متن کاملCommitment of Electric Power Generators Under Stochastic Market Prices
A formulation for the commitment of electric power generators under a deregulated electricity market is proposed. The problem is expressed as a stochastic optimization problem in which the expected profits are maximized while meeting demand and standard operating constraints. First, we show that when an electric power producer has the option of trading electricity at market prices, an optimal u...
متن کاملEfficient Likelihood Estimation in State Space Models
Motivated by studying asymptotic properties of the maximum likelihood estimator (MLE) in stochastic volatility (SV) models, in this paper we investigate likelihood estimation in state space models. We first prove, under some regularity conditions, there is a consistent sequence of roots of the likelihood equation that is asymptotically normal with the inverse of the Fisher information as its va...
