The study assesses the relevance of infrastructural absorptive capacity in the foreign direct investment (FDI)-growth argument in ECOWAS. Though foreign aid has received a vast attention in the literature, however, an assessment of how the infrastructural readiness of the host economies drives the effectiveness of aid was vocal in this re-examination. The study assesses this main thrust in ECOWAS Sub-region for the period 1995-2017 using the system GMM estimation approach. The result suggests that FDI promotes growth though growth responded less proportionately to FDI influx. Alternatively, following the interaction of FDI and physical infrastructures, the responsiveness of FDI declined. Specifically, the responsiveness of GDP growth declined from 29.2% to 0.21% for road infrastructures. It hence becomes expedient for African government and policy makers to channel a viable development path towards enhancing transport and road infrastructures in order to attract financing into the space and the livelihood of poor rural population.

PurposeThis study examined the macroeconomic effects of COVID-19-induced economic policy uncertainty (EPU) in Nigeria. The study considered the effects of three related shocks: EPU, COVID-19 and correlated economic policy uncertainty and COVID-19 shock.Design/methodology/approachFirst, the study presented VAR evidence that fiscal and monetary policy uncertainty depresses real output. Thereafter, a nonlinear DSGE model with second-moment fiscal and monetary policy shocks was solved using the third-order Taylor approximation method.FindingsThe authors found that EPU shock is negligible and expansionary. By contrast, COVID-19 shocks have strong contractionary effects on the economy. The combined shocks capturing the COVID-19-induced EPU shock were ultimately recessionary after an initial expansionary effect. The implication is that the COVID-19 pandemic-induced EPU adversely impacted macroeconomic outcomes in Nigeria in a non-trivial manner.Practical implicationsThe result shows the importance of policies to cushion the effect of uncertain fiscal and monetary policy path in the aftermath of COVID-19.Originality/valueThe originality of the paper lies in examining the impact of COVID-19 induced EPU in the context of a developing economy using the DSGE methodology.
