    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.

    Environmental impact of ISO 14001 certification in promoting sustainable development: The moderating role of innovation and structural change in BRICS, MINT, and G7 economies
    (SAGE Publications Inc., 2024) Ofori, Elvis K.; Asongu, Simplice A.; Ali, Ernest B.; Gyamfi, Bright A.; Ahakwa, Isaac
    Since the industrial era, the selection of energy sources to facilitate economic advancement has been criticized because of the resulting ecological calamity. This has prompted the introduction of radical approaches such as ISO 14001, which tackles the drivers of pollution. Therefore, this study analyses the ISO 14001—environment nexus from three distinct points of view: BRICS, MINT, and G7 countries from 1999–2020. Also, our work fills an extant gap in assessing structural change and innovation’s role in augmenting the relationship. The Driscoll and Kraay estimator is employed as an analytical tool for cross-sectional dependence and slope homogeneity, while the fixed effects approach provides sufficient robustness checks on the findings. While some outcomes vary per bloc, others are relatively similar across the three blocs. That is: (1) ISO 14001 shows an abatement portfolio for only the G7 bloc, and the Full sample. (2) Structural change showed potential for abating carbon emissions in all blocs. (3) Technology led to an increase in pollution in all blocs except for the MINT economy. (4) ICT in the form of mobile phones also help reduce carbon emissions in all three blocs except for their composite. (5) Renewable energy helps reduce carbon emission in all blocs except for G7. ISO 14001 shows the potential to encourage green growth. As a result, policymakers should work to enhance ISO 14001 certification, which might serve as a management tool to promote sustainable development.

    Toward the fourth industrial revolution among E7 economies: Assessment of the combined impact of institutional quality, bank funding, and foreign direct investment
    (SAGE Publications Inc., 2022) Shahbaz, Muhammad; Gyamfi, Bright A.; Bekun, Festus Victor; Agozie, Divine Q.
    Background: Technological innovation and its paradigm, that is, the Fourth Industrial Revolution-4IR, have shown strong impact on income levels of adopters across the globe. To this end, this analysis examines the impact of bank funding and institutional quality on technological advancement. Objectives: This study adds additional variables such as high-technology exports and foreign direct investment (FDI) as control variable. Our study period spans from 2000 to 2018 on an annual frequency for E7 economies (Brazil, Indonesia, Mexico, India, Turkey, Russia, and China). Research Design: This study leverages on cross-sectional ARDL, Augmented Mean Group (AMG), and Common Correlated Effects Mean Group Estimates (CCEMG) estimation techniques to examine long-run relationship between the outlined variables. Subjects: Empirical findings show that institution quality, bank finance, income, high-technology exports, and foreign direct investments exert a positive effect on advancements in technology. Furthermore, the interaction between bank finance and institution quality on technological advancement is also positive and statistically significant. Based on the findings, it is concluded that large-scale funding is crucial for businesses to leverage revolutionary technology. Likewise, access to large capital sources if made easier encourages technology affordance as well as innovation and operational excellence. Thus, economies with established legal and financial systems stand to offer businesses such security, which encourages business innovation. Conclusions: Consequently, E7 economies ought to improve their financial and legal systems to boost financial security, creativity, and competitiveness of businesses.
