Keywords: econometric forecasting, vector autoregression, error correction model , specification testing, forecast comparisons his essay describing a single equation approach is to first test individual variables for the presence of unit roots, then to estimate the cointegrating equation or equations of the. Cointegration ideas as introduced by granger in 1981 are commonly embodied in empirical macroeco- nomic modelling through the vector error correction model (vecm) it has become common practice in these models to treat some variables as weakly exogenous, resulting in conditional vecms.
