Sample Solution

The next test done was the Johansen Cointegration test divided into two test of its own, the Trace test and Max-Eigen Test. The findings from the trace test indicated that there was, at least, one cointegrated equation at 0.05 % level, and the Max-Eigen test also indicated that there was at least 1 cointegrated equation at 0.05 % level as well. These made it necessary in running of Error correction model (ECM) test, which was done using Var. The results of the test showed that FDI had a significant impact on TEL, but the TEL did not have any significant effect on FDI, which was the same test result that gotten when Granger causality test was run on the same variables. It is important to note that both Johansen Cointegration test and Granger causality test were used to determine the relationship between all the variables used, on the long run.

The final test conducted was the General impulse response functions on all the variables, and the test result indicated that there FDI had a significant effect on TEL, while the TEL also had some significant effect on FDI as well. FDI also had a significant effect on GDP, as the GDP had a significant effect on FDI in return. The same circumstance applied when comparing the relationship between TEL and GDP.

The distinction between the General Impulse response functions and the two previous test conducted is that, while those tests were used to check the relationship between all the variables on the long run, the General impulse response function was used to check their relationship on the short run, with a period of 10 months specifically.

5.2 CONCLUSION

They purpose or reason for this research was to determine the impact or effect of information and communication technologies (ICT) on economic growth in Nigeria, via the mobile telecommunication sector. After acquiring all necessary data for the variables used in trying to show the significant impact ICT. The final analysis showed some mixed results, although earlier empirical studie
