Ergodicity, mixing, and existence of moments of a class of Markov models with applications to GARCH and ACD models

Meitz, Mika (contributor); Saikkonen, Pentti (contributor) - 2004 - [Elektronische Ressource], First version October 2004, revised December 2005 and April 2007

This paper studies a class of Markov models which consist of two components. Typically, one of the components is observable and the other is unobservable or 'hidden'. Conditions under which (a form of) geometric ergodicity of the unobservable component is inherited by the joint process formed of...
