Strict stationarity and functional central limit theorem for ARCH/GARCH models

Oesook Lee and Jihyun Kim

Abstract

In this paper we consider the (generalized) autoregressive models with conditional heteroscedasticity (ARCH/GARCH models). We will give conditions under which strict stationarity, ergodicity and the functional central limit theorem hold for the corresponding models.

Keywords: GARCH process, Markov chain, stationarity, ergodicity, functional central limit theorem
