Nigeria as an oil exporting mono-economy is susceptible to fluctuations in the world oil prices. About 97 percent of the government’s revenues are gotten from proceeds from oil export. The study attempts to assess the behaviors of macroeconomic variables in the face of oil price volatility in Nigeria. The empirical evidences reveal that macroeconomic variables were susceptibility to volatility in Oil Price. The theoretical framework is based on the Mundel-Flaming model and adopts the variance decomposition and impulse response functions to explain the dynamic properties of the VAR methodology. The impulse response results reveal that a one standard deviation in oil price will trigger a significant change in RGDP, GEXP, INFLATION and IMPORT both in the short and long run, and IR and EXR significantly only in the short run. Finally, the variance decomposition of RGDP, GEXP and EXR reveals that the variability in them were significantly explained by oil price volatility and other tests ran reveals a consistent result. Therefore, volatility in oil price has direct impact on real GDP, Government expenditure, inflation, interest rate, exchange rate and import. The researchers therefore recommend diversification of the economy to other sectors, financial prudence, sound fiscal policy and the lowering of interest rate to stimulate domestic investment.

We examine drivers of foreign direct investment (FDI) and foreign portfolio investment (FPI) in nine selected African economies, during the period 1980 to 2014, with particular interest in the role of financial market development. We set out to explore the drivers of FDI and FPI in selected African countries, respectively. We employ the dynamic GMM methodology to assess the motivators of inward foreign flows. The results show that FDI inflows are generally dependent on past inflows of FDI, low inflation, infrastructural development, and real GDP growth rate; while stock market capitalisation, commercial bank assets gauged against commercial and central bank assets as well as domestic credit to the private sector by banks intermediate for financial market development. On the other hand, we find that FPI inflows are attracted to foreign destinations due to previous FPI inflows, the real exchange rate, inflation rates and the presence of developed infrastructure. Further, developed financial markets, as proxied by stock market capitalisation, were found to significantly and positively influence inward FPI flows, while a closed financial account and low interest rate discouraged FPI. The significant contribution of this paper is that its findings empirically confirm FDI and FPI theory, as postulated in Dunning’s eclectic paradigm insofar as the main “location” variables that enhance host country attractiveness are concerned, specifically in the African context. In light of these findings, we recommend that policy makers strengthen their domestic markets, complemented by appropriate regulations and institutions to attract foreign investment flows, while reducing their dependency on international aid and loans.
