摘要：

We review the main results of Francq and Zakoian (2001) on stationarity and the autocovariance function for Markov-switching VARMA models. Then we derive a formula in closed form for the spectral density of such models, and describe some new properties of it. Our results improve those obtained by Pataracchia (2011) and complete some of Francq and Zakoian (2001). (C) 2013 Elsevier B.V. All rights reserved.
