Abstract

This note investigates the behaviour of a parameter-constancy test statistic when near I(2) (integrated of order 2) variables are incorporated in a cointegrated vector autoregressive system. Simulation studies indicate that the presence of such variables has a significant impact on size properties of the constancy test.
