    Building Critical Infrastructures: Evaluating the Roles of Governance and Institutions in Infrastructural Developments in Sub-Sahara African Countries
    (SAGE Publications Inc., 2022) Appiah, Michael; Onifade, Stephen T.; Gyamfi, Bright A.
    Background: The Sub-Saharan African (SSA) region has notably been in the limelight of infrastructural deficit discussions over the decades. Although the region’s infrastructural development is gradually improving, the levels and pace of development remain generally poor compared to the rest of the world. Objectives: This study thus aims to empirically examine the roles of governance and institutions in infrastructural developments in the Sub-Sahara African (SSA) region toward addressing the pressing needs for critical infrastructures for the region. Research Designs: The empirical strategies utilized in the study include the Common Correlated Efficient Mean Group (CCEMG) and Dynamic CCEMG methods among others. These empirical approaches were applied to analyze data on governance and institutional quality proxies for the SSA region to achieve the study’s objectives while controlling for the effects of industrial value-added, foreign capital inflow (FDI), and overall economic growth for the understudied period (1990–2019). Results: The results reflect the essence of governance and institutional quality as these variables significantly boost infrastructural development in SSA. In addition, industrialization and growth also show a favorable impact on the development of infrastructure thus reflecting that the transition from agrarian to industrial economies occurs in parallel with infrastructure development in the SSA. However, FDI inflows were not found to be significantly instrumental to infrastructural development in the region. Conclusions: Hence, the SSA must strive to strengthen institutions and harmonize their industrial and economic push with infrastructural developments while encouraging potential foreign investors to diversify investments to infrastructural projects beyond the usual primary sector/resource-based activities.

    Do financial development, foreign direct investment, and economic growth enhance industrial development? Fresh evidence from Sub-Sahara African countries
    (Springer Science and Business Media Deutschland GmbH, 2022) Appiah, Michael; Gyamfi, Bright Akwasi; Adebayo, Tomiwa Sunday; Bekun, Festus Victor
    This study investigates the impact of financial development, economic growth, and foreign direct investment on enhancing industrial growth for a panel of selected Sub-Sahara African (SSA) countries from 1990—2017. However, the present study enriches our understanding of financial development by employing a new comprehensive index focused on the accessibility, scope, and productivity of capital systems and banking institutions and incorporated foreign direct investment and economic growth as significant industrial growth drivers in the selected countries. A more robust technique Augmented Mean Group (AMG) and Common Correlated Effect Mean Group (CCEMG), were employed to access the long-run relationship among the understudy variables. Further empirical results shows that financial development and economic growth enhance industrial development with finance exhibiting signifcance while foreign direct investment is seen as adverse. Moreover, a two-way causality was obtained between industrialization and financial development while both foreign direct investment and economic growth had a one-way causality relationship with industrialization. Thus, our study implies that the government officials within these countries must provide a suitable environment for the public, private partnerships, i.e. private sector, which is the backbone for industrial development.

    Investigating institutional quality and carbon mitigation drive in Sub-Saharan Africa: Are growth levels, energy use, population, and industrialization consequential factors?
    (SAGE Publications, 2022) Appiah, Michael; Li, Mingxing; Onifade, Stephen Taiwo; Gyamfi, Bright Akwasi
    In view of the United Nations’ Sustainable Development Goals on clean and responsible energy consumption, climate change mitigation, and sustainable economic growth (UN-SDGs-7, 11–13), this study examines institutional quality (IQ)–carbon emissions nexus in the framework of the Environmental Kuznets Curve (EKC) hypothesis. Six dimensions of IQ from the World Governance Indicators (WGIs) were used while focusing on Sub-Saharan African (SSA) countries between 1996 and 2019. After controlling for growth, energy use, and industrialization levels, the empirical results validated the EKC hypothesis for the SSA as a unit increase in economic growth initially worsens the environment while further economic expansion eventually improves the environment. However, mixed results were obtained on the effects of IQ indicators. CO2 emissions are only substantially reduced by corruption control, regulatory quality, and the rule of law among other IQ measures. Furthermore, the causality analysis showed a unidirectional causality between growth and environmentally detrimental energy consumption levels coupled with a two-way emission-population growth causality flow as well as a two-way emissions—IQ causality channel. While economic growth, energy use, and industrialization levels undermine environmental sustainability in the SSA region via increased carbon emissions, the overall findings signal the moderating roles of IQ. Hence, the strengthening of institutions is recommended for environmental sustainability enhancement in the SSA region.

    Modeling the asymmetric effects of exchange rate, financial development, and oil prices on economic growth
    (World Scientific, 2024) Appiah, Michael; Gyamfi, Bright Akwasi; Usman, Ojonugwa; Bekun, Festus Victor
    Recent studies on the relationship between exchange rates, oil prices, and economic growth in developing countries like Ghana have used linear methods, but do not account for potential asymmetries. This research investigates the intricate asymmetric effects of exchange rates, financial development, and oil prices on Ghana's growth from 1990-2017 using a nonlinear model. The findings indicate that global oil price has asymmetric effects on short- and long-term growth, with positive price changes having different impacts than negative changes. However, there is no evidence for asymmetric long-term effects of exchange rates and financial development on growth, only short-term asymmetries. The cumulative effects of exchange rates and financial development outweigh oil prices. Recommendations include modernizing fuel efficiency, investing in renewable energy and public transit to address oil price shocks, and increasing market transparency and collaboration between major consumer and producer countries. The nonlinear model provides an evidence-based analysis of the intricate asymmetric relationships between these factors and developing country growth.
