The continuous demand and usage of energy in large quantum for industrial purposes has motivated the global advocacy for energy sustainability (SDG-7). Against this backdrop, this study employed various econometric techniques to study the nexus between clean energy supply in Nigeria and industrial development between 1990 and 2019. This study sets to establish the nature of the relationship in the long run, direction of causality and the stochastic dynamic interaction between clean energy supply and industrial development in Nigeria. Consequently, the following findings emerged from this study; clean energy supply and manufacturing value added had a significant negative relationship. This implies that the contribution of clean energy supply is negatively significant to the manufacturing value added in the Country. Therefore, the supply of electricity production from hydroelectric sources had not led to industrial development in Nigeria. Further evidence indicates that no feedback relationship exists between clean energy supply and industrial development. Also, the stochastic dynamic interaction between clean energy supply and industrial development shows a shock to manufacturing value added determines the behavior of clean energy supply to a larger extent in one hand, whereas, variance decomposition of clean energy supply shows the similar effect on the behavior of industrial development on the other hand. In the light of the findings from this study, the following recommendations are made for the policymakers in Nigeria; in achieving the Sustainable Development Goal (SDG 7), clean energy supply could be explored for future industrial development in Nigeria, thought it currently lacks the capacity to drive the manufacturing sector of the economy. And as such, the Nigerian policymakers and other stakeholders should work hard to achieve sustainable supply of adequate electricity production from hydroelectric sources in the country.

This study examined the relationship between FDI inflows and poverty reduction vis-à-vis Human Development Index in which majority of past studies have not fully explored in Nigeria. Data were extracted from secondary sources with application of ARDL and Bounds test technique. The major findings that came up in this study are as follows; FDI net inflows had an insignificant negative relationship with GDP per capita that measures welfare of the people in terms of the socio-economic benefits in Nigeria. Similarly, net FDI inflows had a negative but insignificant relationship with literacy rate, which measures welfare of the people in terms of educational attainment. Whereas, net FDI inflows had an insignificant positive relationship with life expectancy which measures welfare of the people in terms of health. Consequently, steaming from the principal findings that emerged in this work, the following recommendations are therefore made for the policy makers in Nigeria. When the Nigerian policy makers want to address poverty holistically in the country, the human development variables should be targeted. Also, policy measures that would stimulate FDI inflows into the country should be encouraged, and FDI inflows in the country should be utilized maximally in order to bring poverty reduction in the country in the short run.

The question whether globalization and its corresponding impacts carry a blessing or curse in developing countries has been a controversial issue among both the scholars and the policymakers, against this background this study provided an empirical answer to the question whether globalisation is a curse or cure to industrial development in Nigeria between 1990 and 2019 within the framework of the Fully Modified Ordinary Least Squares (FMOLS) and Granger causality test. Consequently, the following principal findings emerged in this study. Firstly, both FDI inflows and trade openness which depict economic globalization had a negative relationship with industrial development respectively. Though, trade openness was significant while FDI inflows showed otherwise. In the same vein, a unidirectional causality ran from manufacturing value added to FDI inflows. However, no feedback relationship existed between trade openness and manufacturing value added. Therefore, this study submits that economic globalization is a curse to industrial development in Nigeria because the wave of economic globalization contributed a significant reduction in manufacturing value added in Nigeria in the last three decades. From these findings, the current wave of economic globalization could be a cure to industrial development in Nigeria, if only the policymakers in the country embark on policies that would drive the largest proportion of the inflows of FDI in the direction of manufacturing sub sector in the country. Similarly, all hands must be on deck by all the relevant stakeholders to ensure that manufactured products in Nigeria possesses value added quality to facilitate their competitiveness in the global market.

This study has provided an empirical answer to the question whether globalization promotes human development in emerging economies using the case study of BRICS countries. The study subjected the annual data between 1990 and 2019 extracted from the World Bank and UNCTAD databases to econometric analysis. It is important to stress that, in the light of the empirical analyses, the study establishes the following findings; the existence of a co-integrating linkage between globalisation and human development was confirmed in BRICS countries. In the same vein, globalization components-FDI inflows as percentage of GDP and trade openness had a positive and significant relationship with human development in BRICS countries. Moreover, both capital formation and internet users had positive and significant relationship with human development. This is strong evidence that that globalization promotes human development in BRICS countries in the long run. As a result of this finding, this study makes the following recommendations for the policymakers in BRICS countries, and by extension other emerging economies that since the economic components of globalization promote human development in these countries, any time the goal of the policymakers is the achievement of human development in the long run, promotion of policies that would facilitate FDI inflows and trade surpluses simultaneously should be of the priorities by these policymakers.
