We apply panel unit root tests, panel cointegration tests, and panel Granger-causality tests. Our empirical results confirm that all panel unit roots tests are stationary after first difference, and also denotes the long-run relationship through the application of Pedroni and Kao panel cointegration tests among the variables and Granger-causality results supports feedback hypothesis which means a bidirectional relationship between REC and GDP, and TFEC and GDP in both the short-run and long-run, while in contrasts NREC-GDP supports growth hypothesis in long-run and supports neutral hypothesis is the short-run.
