This study investigates the presence of environmental Kuznets curve (non-linear relationship between pollution and the per capita income) in Nigeria, Ghana, Cote d’Ivoire, Mali and Senegal and Gabon. In the study, pollution is regressed on per capita income, squared per capita income, trade intensity, foreign direct investment and population density price. Panel estimation technique and ordinary least square were used to obtain required estimates for all selected countries and individual economies. The study established the presence of environmental Kuznets curve for these countries at group and individual level. It also revealed that the value of turning point in pollution level corresponding to per capita income is varying among countries. From the result, the threshold GDP per capita (constant 2005 US$) is approximately $758 for Nigeria, $7060 for Gabon, $585 for Ghana, $1014 for Cote d’Ivoire, $390 for Mali and $675 for Senegal. The declining trend of pollution with regards per capita income could be attributed to introduction of environmental friendly products, structural changes in the industrial sector of these countries that involve more output per primary resources.

This study examines the effect of financial integration on economic growth in Nigeria. Using time series data from 1981 and 2012, the study employs autoregressive distributed lag (ARDL) bounds testing approach proposed by Pesaran et al., (2001) to estimate the long run and short run effect of financial integration and development on economic growth. The result from cointegration test showed presence of long run relationship between dependent and all explanatory variables. The regression results show that, while financial integration has no short run effect on economic growth, its long run effect on growth is negative and significant. Financial development was found to have both short run and long run positive effect on economic growth in Nigeria. Hence, for Nigeria to benefit from financial integration, the government has to increase the level of competition, improve the quality of financial information and reduce corruption in the financial system.
