Economic Union,Finance and Growth: A Prognosis in West Africa

This paper compares the impact of financial development on economic growth in the Union Économique et Monetaire Ouest Africaine (UEMOA) and non‐UEMOA countries. It also examines the finance‐growth nexus before and after the formation of UEMOA, as well as the indirect effect of economic union on economic growth through the financial sector. The study reveals a significant difference in the finance‐growth nexus between UEMOA and non‐UEMOA countries. Specifically, financial development has a robust positive impact on growth in UEMOA countries, while the impact is tenuous in non‐UEMOA countries. However, we find no remarkable difference in the finance‐growth nexus before and after the formation of UEMOA. We also reveal that economic union has no robust indirect effect on economic growth via the financial sector. The economic implication is that UEMOA could have economic benefits, but financial development is not a channel through which it influences growth. Therefore, it is necessary to reposition the union so that it can enhance the impact of finance on growth.     

Rethinking the impact of GDP on financial development: Evidence from heterogeneous panels

This paper examines the nonlinear impact of real GDP per capita on financial development in a panel of 125 countries. It also determines the moderating effect of inflation on the impact of GDP on financial development. It employs the dynamic panel system generalized method of moments (GMM) and the dynamic common correlated effects (CCE) to do both panel and country‐specific analysis, as well as control for cross‐sectional dependence, heterogeneity and endogeneity. This study shows that GDP has a positive impact on financial development in the entire panel. However, when we split the panel into different income groups, we find a positive impact in the high‐ and middle‐income groups while the impact is insignificant in the low income group. Although we find no evidence of a nonlinear impact of GDP on financial development in the panel, the country‐specific analysis reveals a significant nonlinear relationship between GDP and financial development in 73 countries. We also show that inflation adversely moderates the positive impact of GDP on financial development in middle‐income countries. This study implies that the relationship between GDP and financial development depends on the levels of GDP and inflation rate. We recommend some policy options based on the findings.     

Foreign Capital Inflows and Economic Growth in Nigeria: Any Nexus?

ABSTRACT

This paper examines the impact of foreign capital inflows on economic growth in Nigeria for 1980–2015 period. It employs Autoregressive Distributed Lagged (ARDL)-bounds test, and finds a cointegration relationship between foreign capital inflows and growth. Specifically, foreign portfolio investment has positive impact on growth, while the impact of foreign loans is negative. Nevertheless, foreign direct investment and foreign aid have insignificant impact on growth, suggesting that Nigeria cannot rely on foreign direct investment and foreign aid as vehicles to stimulate growth. Rather, an increase in foreign portfolio investment or reduction in foreign loans has beneficial effects on the economy.     

Finance–Growth Nexus: New Insights from the West African Region

This article examines the impact of financial development on economic growth in the West African region accounting for both structural breaks and cross-sectional dependency. Although the panel data study reveals that financial development has positive impact on economic growth in the entire West African region, the disaggregated data analysis discovers that variations in financial development can only explain variations in economic growth in about 75% of the countries in West Africa. This study has succeeded in revealing the countries where finance accelerates growth and countries where it does not. The weak impact of finance on growth in some of the countries could be due to low income level, low level of financial development, weak institutions, macroeconomic instability, and high inflation rates. Knowing where finance spurs growth and where it does not is fundamental for policymaking.
