Cointegration and the Aggregate Demand for Money Function

  • Apostolos Serletis


We have argued that in a multivariate context with integrated variables it is important to test for cointegration (i.e., long-run equilibrium relationships). If the variables are integrated of the same order, but not cointegrated, ordinary least squares yields misleading results. In fact, Peter Phillips (1987) formally proves that a regression involving integrated variables is spurious in the absence of cointegration. In this case, the only valid relationship that can exist between the variables is in terms of their first differences.
