Malliavin calculus and asymptotic expansion for martingales
We present an asymptotic expansion of the distribution of a random variable which admits a stochastic expansion around a continuous martingale. The emphasis is put on the use of the Malliavin calculus; the uniform nondegeneracy of the Malliavin covariance under certain truncation plays an essential role as the Crame r condition did in the case of independent observations. Applications to stati...
متن کاملMalliavin Greeks without Malliavin Calculus
We derive and analyze Monte Carlo estimators of price sensitivities (“Greeks”) for contingent claims priced in a diffusion model. There have traditionally been two categories of methods for estimating sensitivities: methods that differentiate paths and methods that differentiate densities. A more recent line of work derives estimators through Malliavin calculus. The purpose of this article is t...
متن کاملMalliavin Calculus Method for Asymptotic Expansion of Dual Control Problems
We develop a technique based on Malliavin-Bismut calculus ideas, for asymptotic expansion of dual control problems arising in connection with exponential indifference valuation of claims, and with minimisation of relative entropy, in incomplete markets. The problems involve optimisation of a functional of Brownian paths on Wiener space, with the paths perturbed by a drift involving the control....
متن کاملStatistical inference and Malliavin calculus∗
The derivative of the log-likelihood function, known as score function, plays a central role in parametric statistical inference. It can be used to study the asymptotic behavior of likelihood and pseudo-likelihood estimators. For instance, one can deduce the local asymptotic normality property which leads to various asymptotic properties of these estimators. In this article we apply Malliavin C...
متن کاملPerturbation Analysis and Malliavin Calculus
Using the Malliavin calculus, we give a uniied treatment of the so-called perturbation analysis of dynamic systems. Several applications are also given.
