摘要

In order to boost up the economic growth of any country, Exports should be considered as key factor as it contributes immensely in which Sierra Leone as a nation is no exception. Therefore, this research paper target to investigate the effect of export on the economic growth of Sierra Leone using time series data of exports and the gross domestic products ranging from 1990- 2019 which was source from the World Bank Indicators. In order to accomplish the aim of this paper, descriptive statistics, regression, correlation, Augmented Dickey- Fuller Unit root test, Johansen cointegration test, Vector Auto regression model, diagnostic test and the Pair- wise Granger causality test were the tools used to analyze the data. Based on the results from both regression analysis, it can be seen that export has a significant positive effect on the economic growth of Sierra Leone. Augmented Dickey-Fuller unit root test results shows existence of stationarity at first difference was detected, while the cointegration test results revealed that, there is no relationship between the exports and economic growth. However, the Vector Auto regressive model test revealed that, exports have a significant effect on the economic growth as well. Granger causality test, shows that both exports influence the Gross Domestic Product of Sierra leone.
