    Coal consumption-environmental sustainability nexus in developed and developing major coal-consuming economies
    (Cell Press, 2024) Alhassan, Abdulkareem; Ozturk, Ilhan; AL-Zyoud, Mohammad Fahmi; Bekun, Festus Victor
    Coal is crucial for economic progress but equally baneful to the environment. Thus, the coal consumption-environmental sustainability nexus attracted the attention of both policymakers and scholars. This study evaluates the coal consumption-environment nexus in developed and developing countries over the period 2000-2020. We used panel data econometric techniques and the Augmented Anderson-Hsiao (AAH) two-step GMM estimator to assess and compare the impact of coal consumption on CO2. The findings revealed that the consumption of coal aggravates environmental pollution and hinders environmental sustainability. Thus, this study confirms the environment-destroying effect of coal consumption. However, the findings reveal that the negative consequence of coal consumption on the environment is more for the sample of developed countries than that of developing countries. This suggests that coal use harms the environment developed economies than the developing countries. Specifically, we found that the carbon emissions emanating from a one percent (1%) increase in coal consumption of the developed countries is about six-fold more than that of the developing countries. Therefore, this study suggests a gradual phase-out, rather than sudden phase-out, of coal consumption with greater emphasis on developed countries. The implementation of the coal phase-out policy and the removal of fossil fuel subsidies should start with the developed countries or be made more stringent in such countries than the developing economies. The developed countries should relinquish a greater proportion of their coal consumption than the developing countries.

    Sanctions and economic growth: Do sanction diversity and level of development matter?
    (Cell Press, 2023) Alhassan, Abdulkareem; Sabzehmeidani, Anoush Shabani; Taha, Amjad issa; Haseki, Murat Ismet
    The application of economic and political sanctions becomes a vital tool of international politics to facilitate peaceful coexistence among the nations. However, the issue of the effectiveness of sanctions in creating adequate disutility to ensure compliance remains contentious. Therefore, this study assesses the effect of sanctions on the economic growth of the target states. It captures the diversity of sanctions using system Generalized Method of Moments (GMM) with extensive dataset for the period 1970-2018. The findings reveal that extensive, multilateral sanctions, and export restriction are the only sanction categories that are effective in creating disutility and reducing the real income per capita growth when targeted at the developed countries. On the other hand, limited sanctions (partial embargo) - sanctions that are targeted at specific sectors, groups, and issues such as withdrawal of foreign aid, as well as import restrictions can effectively reduce income per capita growth when imposed on developing countries while all other cate-gories of sanctions have a positive effect on income growth in targeted developing economy. Therefore, we, conclude that the sanctions diversity, development level of the target country and sender identity play vital roles concerning the sanctions-economic growth nexus. These attributes should be considered in the application and analyses of sanctions to ensure their effectiveness. The study provided several interesting policy insights.

    Sustainable electricity consumption in South Africa: the impacts of tourism and economic growth
    (Springer Heidelberg, 2023) Bekun, Festus Victor; Adekunle, Ahmed Oluwatobi; Gbadebo, Adedeji Daniel; Alhassan, Abdulkareem; Akande, Joseph Olorunfemi; Yusoff, Nora Yusma Mohamed
    The current study examines sustainable electricity consumption for economic growth in a small open and tourist economy. The energy-tourism nexus is evaluated for the relationship between sustainable electricity consumption and the international tourist arrival for the South African economy. The present study leverages on annual frequency data for South Africa from 1995 to 2019 for empirical analysis using the ARDL technique. Accordingly, empirical findings indicate a significant direct connection between the sustainable electricity consumption and the international tourism arrival; the study affirms that tourism-induced energy hypothesis is valid in South Africa. However, from a policy standpoint, alternative energy efficiency mechanisms such as renewable energy systems and emancipation of current energy management capabilities are recommended in South Africa. This is necessary for sustainable eco-friendly tourism that engenders clean energy consumption for the study area. More insights into policy caveats are presented in the concluding section.

    Synthesizing the role of technological innovation on sustainable development and climate action: Does governance play a role in sub-Saharan Africa?
    (Elsevier, 2023) Ofori, Elvis Kwame; Ozturk, Ilhan; Bekun, Festus Victor; Alhassan, Abdulkareem; Gimba, Obadiah Jonathan
    The present study draws motivation from United Nation Sustainable Development Goals (UNSDGs) and its impact by 2030. To this end, the current study explored the nexus between energy consumption (SDG-7), climate action (SDG-13), and economic growth (SDG-8) while controlling for role of government apparatus such as like voice of accountability, rule of law, control of corruption and technology innovation in a balanced panel of 46 Sub-Saharan African (SSA) economies from 1996 to 2020. For a robust study, the present study leverages on secondgeneration estimator such as cross-sectional SUR, two-stage least square (2SLS), 2SLS is referred to as the superior estimators to traditional pool OLS due to its capabilities of including endogenous regressors and efficiency. Empirical findings show that all the coefficients associated with mobile subscription (lnTI) are negative and statistically significant at 1% level of significance (P-value <0.01). This indicates that higher (lower) mobile cellular subscriptions results in the reduction (rise) of renewable energy consumption, implying that technological innovation in terms of the expansion of mobile cellular subscription hinders access to clean energy in SSA. Conclusively, the present study presents interesting outcomes concerning technology innovation, Governance, and SDGs goal 7 (clean energy) and 13 (climate action) in Sub-Saharan African blocs. Policy strategies are outlined in the concluding section.

    Towards low carbon and sustainable environment: does income inequality mitigate ecological footprints in Sub-Saharan Africa?
    (Springer, 2023) Gimba, Obadiah Jonathan; Alhassan, Abdulkareem; Ozdeser, Huseyin; Ghardallou, Wafa; Seraj, Mehdi; Usman, Ojonugwa
    This paper contributes to the literature on the environment-economic development nexus by examining whether higher income inequality mitigates environmental degradation in Sub-Saharan Africa for the period 1995-2018. The paper uses the second-generation panel data estimation techniques through the novel augmented Anderson-Hsiao (AAH) estimator. This method allows regressors to be self-instrumenting and efficient with panel data where the cross-sectional units are greater than time and remains valid even when errors are correlated. The result of the Westerlund cointegration confirms the existence of a long-run relationship. Also, the AAH estimation finds that a 1% increase in income inequality is associated with a 0.567 decline in environmental degradation. Furthermore, a rise in GDP per capita is linked to a reduction in environmental pollution. However, it does not validate the existence of the environmental Kuznets curve hypothesis. Population growth and urbanization were found to exacerbate environmental degradation while access to electricity enhances a sustainable environment. To ensure the robustness of the AAH estimation, the Pseudo-Poison Maximum Likelihood Estimator with the high dimensional fixed effects was used. The results showed that, although the effects were smaller, all the coefficients survived. Therefore, our findings substantiate the marginal propensity to emit hypothesis which posits that in economies with high inequality, there is the likelihood that a large proportion of the population would reduce their energy and other carbon-intensive consumption, which consequently improves environmental quality. Although this channel of reducing emissions is not sustainable as it comes with huge economic losses. Policy recommendations were provided.
