Purpose Interaction between environmental pollution and economic growth determines the achievement of the green growth objective of developing economies. An economy turns around the inverted U-shaped environmental Kuznets curve (EKC) when pollution is effectively dampened by social, political and economic factors as such economy grows. Thus, the purpose of this paper is to examine the EKC considering the impact of institutional quality on six variables of environmental pollution (carbon dioxide (CO2), nitrous oxide (N2O), suspended particulate matters (SPM), rainfall, temperature and total greenhouse emission (TGH)) using the case of Nigeria. Design/methodology/approach The EKC model includes population density, education expenditure, foreign direct investment and gross domestic investment as control variables, and it was analysed using the autoregressive distribution lag (ARDL) econometric technique, which has not been applied in the literature on Nigeria. Findings The results, inter alia, indicate that there is EKC for CO2 and SPM. This implies that the green growth objective can be pursued in Nigeria with concerted efforts. Other environmental pollution indicators did not exert significant influence on economic growth. Practical implications Therefore, it is recommended that Nigeria’s institutional quality be strengthened to limit environmental pollution in light of economic growth. Originality/value Previous studies are yet to apply a more developed econometric method, like the ARDL, to estimate the EKC model for Nigeria. This study fills this observed knowledge gap.
This study investigates the implications of large scale foreign land acquisitions on per capita income in Africa. It employs data from World Development Indicators, World Governance Indicators and World Trade Indicators on key variables such as arable land per person, agricultural land as percentage of land area, net food import, regulatory quality, among others (1995-2012) on selected African countries where instances of foreign land deals have been reported. The study formulates empirical models that draw from institutional development theory, which was estimated using Fixed Effects (FE) and Generalised Method of Moments (GMM) techniques in order to handle the issues of country-specific effects and endogeneity. The results from the empirical analysis show that agricultural land influences per capita income significantly. It hereby implies that as more agricultural land are cultivated; the wellbeing of the populace is likely to be enhanced primary through increased income for farmers, increase in real money income for non-farmers, drastic reduction in food inflation and foreign exchange gains for the government. The results of the study suggest the need for controlling the issue of massive foreign land deals through viable institutional framework, though there is need for foreign investment in Africa's agricultural sector but sound institution is pertinent in order to avoid rent seeking behaviour among stalk holders.
