It is also worth noting that even though the error-correction term has been incorporated in all the causality equations, only the equations where the null hypothesis of no cointegration is rejected will be estimated with an error-correction term (see also Narayan and Smyth, 2006; Morley, 2006; Odhiambo, 2009a).
