In this paper we propose a test for a set of linear restrictions in a Vector Autoregressive Moving Average (VARMA) model. This test is based on the autoregressive metric, a notion of distance between two univariate ARMA models, M0 and M1, introduced by Piccolo in 1990. In particular, we show...

This paper examines the steady state properties of the Threshold Vector Autoregressive model. Assuming that the trigger variable is exogenous and the regime process follows a Bernoulli distribution, necessary and sufficient conditions for the existence of stationary distribution are derived. A...

In the present study, we propose a simple test approach based on the work of Breitung and Candelon (2006), which allows us to test for asymmetric predictability at a pre-specified frequency. The test approach can also be used to test for causality in cointegrated systems, as illustrated by...
