A review of asymptotic theory of estimating functions

Jean Jacod, Michael Sørensen

Asymptotic statistical theory for estimating functions is reviewed in a generality suitable for stochastic processes. Conditions concerning existence of a consistent estimator, uni…

Backward stochastic differential equation driven by a marked point process: An elementary approach with an application to optimal control

Fulvia Confortola, Marco Fuhrman, Jean Jacod

We address a class of backward stochastic differential equations on a bounded interval, where the driving noise is a marked, or multivariate, point process. Assuming that the jump…

Efficient estimation of integrated volatility in presence of infinite variation jumps

Jean Jacod, Viktor Todorov

We propose new nonparametric estimators of the integrated volatility of an Itô semimartingale observed at discrete times on a fixed time interval with mesh of the observation grid…

Statistical Properties of Microstructure Noise

Jean Jacod, Yingying Li, Xinghua Zheng

We study the estimation of moments and joint moments of microstructure noise. Estimators of arbitrary order of (joint) moments are provided, for which we establish consistency as w…

A test for the rank of the volatility process: the random perturbation approach

Jean Jacod, Mark Podolskij

In this paper we present a test for the maximal rank of the matrix-valued volatility process in the continuous Ito semimartingale framework. Our idea is based upon a random perturb…

Estimation of volatility functionals: the case of a square root n window

Jean Jacod, Mathieu Rosenbaum

We consider a multidimensional Ito semimartingale regularly sampled on [0,t] at high frequency 1/Δ_n, with Δ_n going to zero. The goal of this paper is to provide an estimator for…
