| Abstract: | We consider a cointegrated vector autoregressive process of integrated order 1, where the process consists of endogenous variables and exogenous variables.

J Econometrics. 2000;97:293–343] considered inference of such processes assuming that the non-stationary exogenous variables are not cointegrated, and thus they are weakly exogenous. We consider the case where exogenous variables are cointegrated. Parameterization and estimation of the model is considered, and the asymptotic properties of the estimators are presented. The method in this paper is also applicable for the models considered in Mosconi and Giannini Non-causality in cointegrated systems: representation estimation and testing.

Finite sample properties of the estimators are also examined through a Monte Carlo simulation. |
