This note studies the geometric ergodicity of nonlinear autoregressive models with conditionally heteroskedastic errors. A nonlinear autoregression of order p (AR(p)) with the conditional variance specified as the conventional linear autoregressive conditional heteroskedasticity model of order q...

Numerous economic models employ a continuum of negligible agents with a sequence of idiosyncratic shocks and random matchings. Several attempts have been made to build a rigorous mathematical justification for such models, but these attempts have left many questions unanswered. In this paper, we...

study this link using two notions of temporal dependence: β−mixing and ρ−mixing. Weshow that β−mixing and ρ−mixing with … exponential decay are essentially equivalent concepts for scalar diffusions. For stationary diffusions that fail to be ρ−mixing …, we show that they are still β−mixing except that the decay rates are slower than exponential. For such processes we find …

In this paper a new mixing condition for sequences of random variables is considered. This mixing condition is termed … ã-mixing. Whereas mixing conditions such as á-mixing are typically defined in terms of entire ó-fields of sets … generated by random variables in the distant past and future, ã-mixing is defined in terms of a smaller class of sets: the …
