Compared to the ordinary threshold model, where typi-cal the lag variable xt-' is the threshold variable, this is a somewhat indirect way of formulating a nonstationary threshold VAR model. In this article, we start directly from the VAR representation (1.1) and then move to the threshold VAR representation (1.4)
