Table 3. ARDL bound test for cointegration.

F-Statistic Critical Value Lower Bound Value Upper Bound Value Conclusion
4.306 1% 3.41 4.68 Cointegration
2.5% 2.96 4.18
5% 2.62 3.79
10% 2.26 3.35

The lag lengths applied in testing the model were selected based on Akaike’s information criteria(AIC) and resulted in ARDL (1,1,2,1,2,1) models. The calculated F-statistics of the bound tests are compared with the critical values obtained from Persaran [39] for k = 6.
