Separate cointegration in a VAR system subject to structural breaks

Economics Letters, 2019, vol. 179, issue C, 19-23

Abstract: This note demonstrates that the analysis of separate cointegration can be facilitated by properly allowing for regime shifts in the underlying data generation process. A vector autoregressive (VAR) model is reformulated in such a way that it is subject to deterministic breaks and also contains the structure of separate cointegration. A comparative empirical study shows the advantage of the proposed VAR model over the standard model in revealing the structure.
