The potential for information technology penetration in sub-Saharan Africa (SSA) is very high compared to other regions. Unfortunately, productivity levels in the area are also deficient. This study investigates the importance of information technology in influencing the effect of foreign direct investment (FDI) on total factor productivity (TFP) dynamics. The focus is on 25 countries in SSA. Information technology is measured with mobile phone and internet penetration, while the engaged TFP productivity dynamics are TFP, real TFP, welfare TFP, and real welfare TFP. The empirical evidence is based on the Generalized Method of Moments. The findings show that except regressions about real TFP growth for which the estimations do not pass post-estimation diagnostic tests, it is apparent that information technology modulates FDI to positively influence TFP dynamics (i.e., TFP, welfare TFP, and welfare real TFP). Policy and theoretical implications are discussed. [ABSTRACT FROM AUTHOR]
