Abstract

This study examined the impact of international capital inflow on economic growth in Nigeria using time series quarterly data from 1981Q1 to 2023Q4. The specific objectives of the study were to evaluate the impact of international capital inflow on economic growth, determine the direction of causality between international capital inflow and economic growth; and to determine the nature of the relationship between international capital inflow and economic growth in Nigeria. The data were sourced from the Central Bank of Nigeria and the National Bureau of Statistics, 2023.   The theoretical framework of this study was the Augmented Solow-Swan version of the Neo-Classical Model because of its dynamism. The dependent variable used in the work was economic growth (GDPGR) and the independent variables were foreign direct investment (FDI), remittances (REM), exchange rate (EXR), trade openness (TOP), and gross fixed capital formation (GFCF). The techniques used by this study were the Classical Multiple Regression Model and the Autoregressive Distributed Lag (ARDL) model. The findings of the long run ARDL showed that all the variables had positive impact on economic growth except gross fixed capital formation. This indicates that an increase in FDI, REM, and EXR had individually insignificant positive impact on economic growth It was also indicated from the findings that trade openness had significant impact on economic growth in Nigeria. The result of the short run dynamic of the ARDL showed that remittances and gross fixed capital formation had negative and insignificant impact on economic growth in Nigeria. The result further indicated that Foreign Direct Investment (FDI), Exchange Rate (EXR) and Trade Openness (TOP) had positive relationship with economic growth in Nigeria. The impact of trade openness on economic growth was statistically significant within the short run and the long run. The result of the co-integration test showed a long-run relationship between international capital inflow and economic growth in Nigeria. This study also showed no evidence of direction of causality between capital inflow and economic growth. The study therefore recommended the need to consciously improve the business environment, such as insurgence, kidnapping and other related security threat to enable capital inflow contribute more to economic growth in Nigeria. The study also recommended that the government should develop Nigeria’s local financial markets for easy inflow of capital.
