Foreign direct investment and economic growth in Sub-Saharan Africa: A nonlinear analysis

Using the threshold regression model, we examine the effects of Foreign Direct Investment (FDI), and the mediating role of FDI absorptive capacity, on economic growth in Sub-Saharan Africa. We find that the threshold level of FDI inflows per person is approximately US$ 44.67 per annum. For FDI to have an appreciable impact on economic growth, countries must have minimum ca-pacity to absorb the growth-enhancing benefits of FDI. For instance, the technology gap between the hosted foreign enterprises and domestic enterprises should be no less than 0.6904. Thus, achieving the FDI threshold level is a necessary, but not sufficient, condition for economic growth. Some countries use tax incentives to improve FDI inflows. We argue that such incentives may be counterproductive at low levels of FDI inflows: FDI coefficient estimates below the lowest threshold level are negative, implying that the higher costs of such incentives exceed the po-tential benefits availed by FDI's direct contribution to economic output and spillovers.(c) 2022 Elsevier B.V.
