Note(s): The lag used for each test is determined using the general-to-specific method (Ng and Perron, 1995) with a maximum lag order of 8 allowed. The null hypothesis under test is no co-integration. Approximate critical values for the tmax and Φ tests are taken from Tables 1 and 2 in Enders and Siklos (2001). For the tmax test statistic, critical values are −1.71 for the 10% significance level, −1.91 for the 5% significance level and −2.34 for the 1% significance level. For the Φ test statistic, critical values are approximately 5.23 for the 10% significance level, 6.35 for the 5% significance level and 8.94 for the 1% significance level. Statistical significance is indicated by triple asterisks (***) for the 1% level
