Testing for the cointegrating rank of a VAR process with structural shifts

Tests for the cointegrating rank of a vector autoregressive process are con sidered that allow for possible exogenous shifts in the mean of the data-ge neration process. The break points are assumed to be known a priori. It is proposed to estimate and remove the deterministic terms such as mean, linea r-trend term, and a shift in a first step. Then systems cointegration tests are applied to the adjusted series. The resulting tests are shown to have known Limiting null distributions that are free of nuisance parameters and do not depend on the break point. The tests are applied for analyzing the n umber of cointegrating relations in two German money-demand systems.
