In this study attempts has been made to examme the relationships and impact of the keyrnliberalizations and/or globalization variables in economic growth in Sub-Saharan Africa (SSA).rnUsing panel data, this paper essentially explores the effects of openness to international trade andrnforeign direct investment (FOI) on economic growth. Given the data and objectives of this study,rnwe used Fixed Effect after testing for long-run relationship using panel co-integration test onrnvariables under consideration. In the due process, there are two analyses were undertaken. First,rnthe time series properties of the variables were ascertained by using the Hadri Panel data unitrnroot test procedure. The results indicate that some of the key variables are J(l). Then, the resultsrnfrom Larson and Johansen panel co-integrating procedw-es indicates that there is no need to usernError Correction Mechanism (ECM) rather it is appropriate to use the OLS estimation techniquesrnof Fixed-Effect or Random-Effect Model. The specification test which we used, Hauseman test,rnfavored the Fixed-Effect Model based on our datarnAlmost all the estimation results showed that openness to Foreign Direct Investments (FOI) hasrnpositive and significant impact while openness to international trade is insignificant and oftenrnnegatively affect growth of low-income countries of Sub-Saharan African. The results indicaternthat openness benefits the high-income group than the low-income group in SSA.rnTherefore, policy measw-es, which aIm to bring economic growth through liberalization andrnintegration, need to go beyond openness to international trade. It is worth for SSA countriesrnindividually and collectively to creating an enabling environment for investment, enhances thernvolume of trade at the regional and international levels to increase their level of income. Theyrnneed to take measures in the areas of improving their human capital development (education orrnadult literacy etc), industrial value creation and financial deepening.
