....by a structural break and if so, when this break takes place. This is important since in the presence of a structural break, the standard cointegration tests such as those proposed by Engle and Granger have low power, i.e. the rejection frequency of the ADF test is clearly reduced (e.g. Gregory et al. 1996). The cointegration relationship is described by equation (3) using the 3 This unit root test is based on a series of sub samples which span one quarter of the total sample each and comprise data from t = 1 to k, t = 2 to k 1, until t = n to T. The recursive min t is found as the smallest ....
