Abstract
This study examines the direct and indirect effects of ICT infrastructure on the economic growth of ECOWAS from 2005 to 2022. It employs the PMG model and the Dumitrescu and Hurlin causality test. Findings reveal that ICT does not directly influence economic growth. The interactive impact of ICT and FDI fosters economic growth. The findings are robust to DOLS and FMOLS. In the long run, a threshold of between 2.6388 and 5.2317 FDI net inflows (% GDP) should be exceeded in order for the moderating incidence of FDI on ICT to promote economic growth. Policy implications are discussed.
