摘要:
We study a class of GARCH models where the parameters are allowed to depend on the state of an unobserved Markov chain. Necessary and sufficient stationarity conditions are given. The consistency of the maximum likelihood estimator is shown. The identification problem is also considered. (C) 2000 Academie des sciences/Editions scientifiques et medicales Elsevier SAS.
