Öğe Another look at the nexus between economic growth trajectory and emission within the context of developing country: fresh insights from a nonparametric causality-in-quantiles test(SPRINGER, 2022) Adebayo, Tomiwa Sunday; Bekun, Festus Victor; Rjoub, Husam; Agboola, Mary Oluwatoyin; Agyekum, Ephraim Bonah; Gyamfi, Bright AkwasiAchieving environmental sustainability has become a global concern amidst increasing climate change threat. Using quarterly frequency data for the case of Russia from 1992 to 2018, the present study explores the interaction between disaggregated energy consumption (renewable energy and non-renewable energy), trade flow and economic growth on a broader measure for environmental degradation (ecological footprint). The choice of the variables draws strength from initiative of the United Nations Sustainable Development Goals (UN-SDG, 7, 8 11 and 13) for responsible energy consumption and clean energy consumption while mitigating climate change issues. The study applied the quantile-on-quantile regression (QQR) and nonparametric causality-in-quantiles to capture these associations. The outcomes from the QQR disclosed that in the majority of the quantiles, trade openness and renewable energy use contribute to environmental sustainability, while nonrenewable energy amplifies ecological footprint. Furthermore, growth in Russia escalates its ecological footprint. Moreover, in the majority of the quantiles, all the exogenous variables can predict ecological footprint. Given the outcomes of this study, it outlines the need for a paradigm shift for alternative and clean energy consumption in Russian energy mix amidst its economic growth trajectory while accounting for green-development approaches. Pathways to fully achieve the sustainability targets are carefully outlined in the concluding section.Öğe Beyond the Environmental Kuznets Curve in South Asian economies: accounting for the combined effect of information and communication technology, human development and urbanization(Springer Science and Business Media B.V., 2023) Gyamfi, Bright Akwasi; Agozie, Divine Q.; Bekun, Festus Victor; Köksal, CihatThe aim of this study is to investigate the role of information and communication technology (ICT) and human capital development on environmental degradation (CO2) using the Environmental Kuznets Curve (EKC) framework in line with the 21st Conference of the Parties to the UNFCCC (COP21). Five South Asian countries namely: Bangladesh, India, Nepal, Pakistan and Sri Lanka were considered in the context of the present study between the annual time period of 1990 to 2016. Pedroni cointegration test and Kao’s residual cointegration test are used to assess long term relationship while Dumitrescu and Harlin (Econ Model 29:1450–1460, 2012) is used to test causality relationship between the variables. Empirical findings from the study showed significant effects of ICT import, renewable energy usage and human development decrease CO2 levels while ICT export and urbanization increase carbon emission levels in the long run. Furthermore, a significantly positive association is observed between economic growth and CO2 emission while the square of national income exerts a significantly negative effect on environmental degradation, which supports the EKC for the South Asian states. From a practical implication context, policymakers should not only concentrate on their economic growth trajectory improvement but also enhance the improvement of their ICT infrastructure, invest more in renewable energy sources, follow policies that would help the countries to raise human development standards, as well as consciousness for environmental sustainability should be pursued.Öğe Can information and communication technology and institutional quality help mitigate climate change in E7 economies? An environmental Kuznets curve extension(Springer Science and Business Media Deutschland GmbH, 2022) Gyamfi, Bright Akwasi; Ampomah, Asiedu B.; Bekun, Festus V.; Asongu, Simplice A.Understanding the role of information communication and technology (ICT) in environmental issues stemming from extensive energy consumption and carbon dioxide emission in the process of economic development is worthwhile both from policy and scholarly fronts. Motivated on this premise, the study contributes to the rising studies associated with the roles of economic growth, institutional quality and information and communication technology (ICT) have on CO2 emission in the framework of the 21st Conference of the Parties (COP21) on climate convention in Paris. Obtaining data from the emerging industrialized seven (E7) economies (China, India, Indonesia, Russia, Mexico, Brazil and Turkey) covering annual frequency from 1995 to 2016 for our analysis achieved significant outcome. From the empirical analysis, economic globalization and renewable energy consumption both reduce CO2 emissions while ICT, institutional quality and fossil fuel contribute to the degradation of the environment. This study affirms the presence of an environmental Kuznets curve (EKC) phenomenon which shows an invented U-shaped curve within the E7 economies. On the causality front, both income and its square have a feedback causal relationship with carbon emissions while economic globalization, institutional quality, ICT and clean energy all have a one-way directional causal relationship with CO2 emissions. Conclusively, the need to reduce environmental degradation activities should be pursued by the blocs such as tree planting activities to mitigate the effect of deforestation. Furthermore, the bloc should shift from the use of fossil-fuel and leverage on ICT to enhance the use of clean energy which is environmentally friendly.Öğe Can technological innovation, foreign direct investment and natural resources ease some burden for the BRICS economies within current industrial era?(Elsevier Ltd, 2022) Gyamfi, Bright Akwasi; Agozie, Divine Q.; Bekun, Festus VictorEconomic advancement has tended to affect the processes of industrialization, which has increased the value of exploited natural resources via the application of technology. Intensive use of natural resources via total reserves, technological innovation, foreign direct investment (FDI), and renewable energy can have an impact on the environment. Considering this, the present study investigates the nexus between industrialization, total reserves, inflows of FDI, technical innovation, renewable and natural resources, and CO2 emissions in the case of BRICS. To this end, annual frequency data for BRICS from 1990 to 2019 are employed in panel framework. The study employs a battery of econometric techniques, namely the Augmented Mean Group (AMG), Common Correlated Effects Mean Group (CCEMG), and Driscoll-Kraay estimators to explore the underlined relationship. The cointegration results based on Westerlund, J. (2007) show that there exists a long-run equilibrium relationship between the study outlined variables over the investigated period. From the empirical analysis, technological innovation and renewable energy both reduce CO2 emissions while industrial value-added, natural resources, FDI and total reserves contribute to the degradation of the environment. Additionally, the interaction between industrial value-added and technological innovation also has negative impact on the BRICS countries’ environment. Based on these outcomes, the BRICS economies are enjoined to pursue green technology growth without compromise for environmental quality in the bloc. Finally, numerous significant policy ramifications for protecting environmental quality in BRICS economies have been proposed in the concluding section.Öğe Discerning the role of renewable energy and energy efficiency in finding the path to cleaner consumption and production patterns: New insights from developing economies(Elsevier, 2022) Shahbaz, Muhammad; Nwani, Chinazaekpere; Bekun, Festus Victor; Gyamfi, Bright Akwasi; Agozie, Divine Q.This study provides empirical evidence on the relationship between energy efficiency and production-and -consumption based carbon emissions by assessing the impact of population size, income, and clean energy on the carbon dioxide (CO2) emissions function. Method of Moments Quantile Regression (MM-QR) and Augmented Mean Group (AMG) estimators are applied to observe long-term associations between the variables, and Dumitrescu-Hurlin (DH) Ganger causality test is used to identify the direction of causality. Findings reveal that, across all specifications, energy intensity and population size have positive (increasing) impact on both estimates of CO2 emissions while renewable energy use has a negatively significant impact and stronger on consumption -based estimates. The presence of an inverted U-shaped curve in the relationship between per capita income and CO2 emissions, as predicted by the Environment Kuznets curve (EKC) hypothesis, only exists when CO2 emissions are calculated based on production pattern. Further empirical analysis based on DH causality tests show a bidirectional causality between energy intensity and production-based CO2 emissions, population size and consumption-based CO2 emissions, per capita income and consumption-based CO2 emissions, and energy in-tensity and renewable energy use. In addition, a unidirectional causality runs from per capita income to production-based CO2 emissions, and from energy intensity and renewable energy use to consumption-based CO2 emissions. This analysis outlines a paradigm for the formulation of a green development strategy in developing economies via energy and environmental resources.Öğe 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 VictorThis 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.Öğe Do natural resource volatilities and renewable energy contribute to the environment and economic performance? Empirical evidence from E7 economies(Springer Science and Business Media Deutschland GmbH, 2022) Gyamfi, Bright Akwasi; Adebayo, Tomiwa SundayThe economies of the emerging seven (E7) are not insulated from the climate change challenges, which is a key concern for most countries. The E7 nations have undertaken part in initiatives to combat climate change, particularly in terms of reducing CO2 emissions from the trajectory of productivity expansion in their countries. It is for this reason that this study examines the impact of resource volatility, renewable energy, and fossil fuel on both economic performance and CO2 emission from 1990 to 2018. The present study used panel quantile regression and Driscoll-Kraay fixed effect-OLS estimators to examine these associations. From model I, the outcome shows that economic performance, natural gas rent, coal rent, and fossil fuel impact CO2 emission positively. Moreover, oil rent, renewable energy, investment in energy, and the interaction between investment in energy and renewable energy also negatively and significantly impact CO2 emission. On the other hand, model II which has economic performance as a dependent variable shows that all the understudy variables have significant positive relations with economic performance. Based on the empirical outcome, policy ramifications are provided.Öğe Energy intensity among European Union countries: the role of renewable energy, income and trade(Emerald Publishing, 2022) Gyamfi, Bright Akwasi; Kwakwa, Paul Adjei; Adebayo, Tomiwa SundayPurpose – The International Energy Agency states that the global energy intensity must reduce by 2.9% yearly before attaining Sustainable Development Goal 7.3 by 2030. However, the European Union (EU) seeking to attain a climate-neutral EU by 2050 shall require a substantial rate of reducing energy intensity. Consequently, this study aims to investigate how (clean) renewable energy, income, trade openness, technological innovation and nonrenewable energy consumption impact energy intensity for the EU countries. Design/methodology/approach – The quantile regression, augmented mean group and causality techniques were used for analyses. Panel data for 26 EU nations over the 1990 and 2019 period was used. Findings – The empirical evidence indicates that the variables have long-run equilibrium relationships. However, the analysis revealed that clean energy and income reduce energy intensity whiles trade, technological innovation and nonrenewable energy consumption increase energy intensity. An interactive term analysis shows that renewable energy and trade interact to reduce further, the negative effect of income on energy intensity. Causality results revealed a feedback connection between energy intensity and clean energy, income, trade liberalization as well as the interaction between income and trade liberalization. A oneway causality was obtained between energy intensity and technological innovation, nonrenewable energy consumption and the interaction between clean energy and income. Practical implications – The results imply that EU countries stand to gain if more resources are committed to encouraging the production and consumption of cleaner/renewable energy. Advancement in policies that support renewable energy and facilitate green growth will help reduce energy intensity for the region. Trade policies that promote lower energy consumption should be strengthened. Originality/value – The effect of renewable energy on energy intensity is assessed. The moderating impact of renewable energy and trade openness on the income–energy intensity relationship for the EU countries is examined. Moreover, this study uses the quantile estimation technique to assess the nonlinear effect of the explanatory variables on energy intensity.Öğe Environmental consequences of foreign direct investment influx and conventional energy consumption: evidence from dynamic ARDL simulation for Turkey(Springer Science and Business Media Deutschland GmbH, 2022) Agboola, Phillips O.; Hossain, Md. Emran; Gyamfi, Bright Akwasi; Bekun, Festus VictorThe preponderance of emerging economies confronts signifcant trade-ofs between economic growth and environmental sustainability considerations, and Turkey is no exception. This study draws strength from the United Nations Sustainable Development Goals (UN-SDGs-7,11,12 & 13). To this end, the present study explores the role of the environmental Kuznets curve (EKC) hypothesis for the case of Turkey for annual frequency data from 1970 to 2020. The present study leverages on the novel dynamic autoregressive-distributed lag (DARDL) methodology and Bayer and Hanck combined cointegration test. The combined Bayer and Hanck cointegration test alongside ARDL bounds test traces equilibrium relationship between economic growth, urbanization, FDI, energy use, and CO2 emission over the investigated period. Empirical results from the DARDL simulation analysis validates the EKC hypothesis. These results suggest that environmental quality is being compromised for economic growth at the earlier stage of economic growth (scale stage). The EKC phenomenon is afrmed as a 1% increase in economic growth increase emission level by 0.1580% and quadratic economic growth decrease emission by 0.1095% in the short and long run, respectively. Similarly, urbanization and energy used in both the short and long run also worsen environmental quality while FDI infux in the long run improves environmental quality in Turkey. These outcomes have far-reaching environment-urbanization growth implications. From a policy lens, the current study subscribed to the environmental stick policies and investment on strategies on a paradigm shift from fossil-fuel energy consumption base to renewables. Further insights are highlighted in the concluding section.Öğe Environmental sustainability and ecological balance dilemma: accounting for the role of institutional quality(Springer Science and Business Media Deutschland GmbH, 2022) Agboola, Phillips O.; Bekun, Festus Victor; Agozie, Divine Q.; Gyamfi, Bright AkwasiGlobal warming is a global menace mainly driven by human anthropogenic activities. There is a need for environmental sustainability amidst increased economic growth. To this end, this study draws motivation from the United Nations Sustainable Development Goals (UNSDGs) with special focus on climate change mitigation and ecological balance. Thus, the present study analyses the dynamic relationship between economic growth, conventional energy consumption, access to technological innovation, economic globalisation, and the pertinent role of institutional quality for the case of the Russian Federation. This study employed novel combined Bayer and Hack cointegration test in conjunction with Pesaran’s ARDL bounds testing for robustness. Both tests validate a long-run equilibrium relationship between the outlined variables. Furthermore, empirical results show that increase in economic activities and consumption of energy that stem from a fossil-fuel basis both have deteriorating effect on environmental sustainability for Russia. Additionally, effect of globalisation shows mixed results, such as, in the short run, economic globalisation dampens environmental quality as increase in global integration exacerbates environmental quality, while, in the long term, globalisation improves the quality of the environment. On the contribution of institutional quality, it improves environmental sustainability over the investigated period. Interestingly, renewable is seen as a panacea for environmental sustainability in the Russian Federation given its pertinent effect to improve the environment of Russia. From a policy lens, there is need for a paradigm shift to renewables and clean technologies to mitigate the effect of climate change issues. The concluding section presents more policy strategies.Öğe Exploring the impact of economic growth on environmental pollution in South American countries: how does renewable energy and globalization matter?(Springer Science and Business Media Deutschland GmbH, 2022) Ali, Ernest Baba; Shayanmehr, Samira; Radmehr, Riza; Amfo, Bismark; Awuni, Joseph A.; Gyamfi, Bright Akwasi; Agbozo, EbenezerMost emerging economies and the South American Countries are no exception to the negative consequences of trade-off between economic growth and environmental sustainability decisions. This study draws strength from the United Nations Sustainable Development Goals (UN-SDGs-7, 11, 12, and 13). Therefore, this study examines the environmental nexus between economic growth, globalization, renewable, and non-renewable energy, in South America from 1995 to 2020. We deployed the pooled mean group (PMG), mean group (MG), and dynamic fixed effects (DFE). Cross-sectional dependence, panel unit root, and cointegration tests were performed. Finally, we used the Dumitrescu and Hurlin test of causality to determine the long-run association between variables. The finding indicates that while environmental pollution increases with increasing economic growth, it decreases with increasing renewable energy both in the short and long term. Whereas economic globalization positively affects environmental pollution in the long term, social globalization and the moderation effect between political globalization and renewable energy improves environmental quality in the long run. Finally, a bidirectional causality was found between economic growth and environmental pollution, with a unidirectional causality running from economic, political, and social globalization, renewable, and non-renewable energy to environmental pollution. Given these findings, we discussed potential policy measures.Öğe Glasgow climate change conference (COP26) and its implications in sub-Sahara Africa economies(Elsevier, 2023) Adedoyin, Festus Fatai; Bekun, Festus Victor; Hossain, Md. Emran; Ofori, Elvis kwame; Gyamfi, Bright Akwasi; Haseki, Murat İsmetAlternative energy has been hailed as a feasible resolution to the environmental degradation and energy problems that have plagued Sub-Saharan Africa (SSA) recently. The expansion of the clean energy sector, on the other hand, relies on economic growth, effective governance, and financial considerations. As a result, it is important to investigate the links between these variables in SSA. This study investigated the influence of economic growth, institutional quality, foreign direct investment (FDI), and financial development on renewable energy at the national threshold in SSA using a two-step difference GMM model based on panel data collected from 2002 to 2019. The outcome shows that economic growth and all three financial development indicators (FD1, FD2 and FD3) have a positive significant relationship with renewable energy. Furthermore, for SSA countries, FDI, as well as all six proxy factors for institutional quality, had a negative significant influence on renewable energy. Our empirical findings propose a variety of policies that might help the renewable energy sector grow.Öğe How do environmental tax and renewable energy contribute to ecological sustainability? New evidence from top renewable energy countries(Taylor and Francis Ltd., 2023) Shayanmehr, Samira; Radmehr, Rıza; Ali, Ernest Baba; Ofori, Elvis Kwame; Adebayo, Tomiwa Sunday; Gyamfi, Bright AkwasiThe recent COP27 has propelled nations towards achieving reduced environmental degradation. Governments are, therefore, required to develop effective policy tools to improve their environmental sustainability plans. In line with this, an empirical study is required to explore the all-inclusive effect of ecological sustainability policy on ecological footprint (EFP) among the world’s top renewable energy consumption countries from 1994 to 2018. Recent studies on environmental degradation have focused on renewable energy while neglecting the role of environmental tax. Thus, the current study fills this gap by exploring the role of environmental tax on ecological footprint. Furthermore, the study evaluates the direct and indirect impact of environmental tax and renewable energy on different levels of EFP using the method of moment quantile regression (MMQR). The DOLS, FMOLS, and panel GMM techniques are also applied to check the robustness of the MMQR results. The empirical results indicate that environmental tax and renewable energy directly and significantly reduce the EFP; however, these impacts are insignificant in countries with lower levels of environmental pollution. Furthermore, the findings indicate that environmental tax plays a leading role in changing the energy structure towards environmentally friendly energies. The results also show that economic globalization and human capital impact ecological footprint negatively. Finally, the results suggest that GDP and nonrenewable energy aggravates ecological footprint. The study results propose insights for policymakers to mitigate environmental degradation by boosting environmental tax to deter polluters and investing more in renewable energy development.Öğe Impact of financial development, trade flows, and institution on environmental sustainability in emerging markets(SAGE Publications Inc., 2023) Bekun, Festus Victor; Gyamfi, Bright Akwasi; Köksal, Cihat; Taha, AmjadThe present study is motivated by the need to decouple economic growth from environmental degradation given the new wave of chase for higher economic growth trajectories comes with its environmental cost implications, especially among developing blocs like the Emerging 7 (E7) countries. There is a consistent trade-off between economic growth versus environmental quality. Government apparatus are perpetually on the chase for low-carbon emission policies via the pursuit for green economy. To this end, this present study extends the conventional environmental Kuznets curve (EKC) argument by incorporating the role of institution in emerging industrialized economies (E7) and using second-generation panel analysis methods like mean group (MG), augmented mean group (AMG), common correlated effects mean group (CCEMG), and the Dumitrescu and Hurlin causality test for more robust estimates and inferences. To this end, we explore the long-run and causality relationship between economic growth, quadratic form of economic growth, institutional quality, trade flow, investment in energy sector, and financial development in an EKC environment. Empirical analysis established a long-run equilibrium relationship among the outlined variables over the study period. The long-run regression shows the presence of EKC in the E7. Thus, suggesting the preference for GDP growth over environmental quality at the earlier stage of growth curve. Interestingly, investment in energy, trade flow dynamics across the blocs, and financial development dampens the detrimental effect of environmental pollution as we observed negative relationship with the ecological footprint. On the contrary, quality of institution is weak as institutional quality increase (worsen) the quality of environment in the E7 economies. From a policy perspective, this current study proposed the need for more stringent environmental treaties and regulations and promotion of green economy without compromising economic growth. In the conclusion part of the study, more details and specifics about the policy blueprint are presented.Öğe 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 AkwasiIn 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.Öğe Is sustainable energy consumption, technological advancement and urbanization fast addressing south Asia’s green energy expansion deficits?(Springer Science and Business Media B.V., 2024) Gyamfi, Bright Akwasi; Adebayo, Tomiwa Sunday; Agozie, Divine Q.; Bekun, Festus Victor; Koy, AybenThe United Nation’s sustainable development goals (UN-SDGs) like accessibility to renewable energies (SDG-7), sustainable production and consumption (SDG-12), as well as stable economic growth all centre on the notion of human development (HDI) and reflected in (SDG-8). In line with this motivation, this study explores the environmental sustainability targets for a panel of South Asian economies that are disproportionately affected by a huge energy deficit i.e., energy poverty, and technological immobility. This study considers evidence from south Asian nations to provide the role of certain indicators of human development in the wake of economic development and environmental quality objectives by unraveling the complex relationships between per capita income, access to technological innovation, access to clean energy, and urbanization. Employing a balanced panel econometric model, this study investigate the hypothesized nexus between specific macro-economic variables among South Asian economies. The empirical evidence indicates that the human development index (HDI), per capita income, accessibility to clean energy, technological innovation, as well as urbanization all exhibits a long-run equilibrium relationship over the study period. However, income per capita, accessibility to clean energy and technological innovation all exert a positive impact on HDI for the selected countries, while urbanization shows a negative impact on HDI. Furthermore, causality relationship shows a feedback causality relationship between income per capita, access to clean energy and urbanization with the human development variable, while access to technological innovation has a one-way causality with the HDI. This current study importantly extends the extant knowledge, by presenting new insights into the interaction between human development and its antecedents from a whole new contextual perspective. These outcomes will assist policymakers and stakeholders to obtain new insights into the crucial role of clean energy accessibility, technological innovation, income per capita, and urbanization on HDI processes among South Asian countries.Öğe Machine Learning Applications in Renewable Energy (MLARE) Research: A Publication Trend and Bibliometric Analysis Study (2012–2021)(MDPI, 2023) Ajibade, Samuel-Soma M.; Bekun, Festus Victor; Adedoyin, Festus Fatai; Gyamfi, Bright Akwasi; Adediran, Anthonia OluwatosinThis study examines the research climate on machine learning applications in renewable energy (MLARE). Therefore, the publication trends (PT) and bibliometric analysis (BA) on MLARE re search published and indexed in the Elsevier Scopus database between 2012 and 2021 were examined. The PT was adopted to deduce the major stakeholders, top-cited publications, and funding organi zations on MLARE, whereas BA elucidated critical insights into the research landscape, scientific developments, and technological growth. The PT revealed 1218 published documents compris ing 46.9% articles, 39.7% conference papers, and 6.0% reviews on the topic. Subject area analysis revealed MLARE research spans the areas of science, technology, engineering, and mathematics among others, which indicates it is a broad, multidisciplinary, and impactful research topic. The most prolific researcher, affiliations, country, and funder are Ravinesh C. Deo, National Renewable Energy Laboratory, United States, and the National Natural Science Foundation of China, respectively. The most prominent journals on the top are Applied Energy and Energies, which indicates that journal reputation and open access are critical considerations for the author’s choice of publication outlet. The high productivity of the major stakeholders in MLARE is due to collaborations and research funding support. The keyword co-occurrence analysis identified four (4) clusters or thematic areas on MLARE, which broadly describe the systems, technologies, tools/technologies, and socio-technical dynamics of MLARE research. Overall, the study showed that ML is critical to the prediction, operation, and optimization of renewable energy technologies (RET) along with the design and development of RE-related materials.Öğe 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 VictorRecent 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.Öğe Quantifying the Dynamic Factors Influencing New-Age Users' Adoption of 5G Using TAM and UTAUT Models in Emerging Country: A Multistage PLS-SEM Approach(Hindawi Limited, 2023) Dadhich, Manish; Rathore, Sumangla; Gyamfi, Bright Akwasi; Ajibade, Samuel-Soma M.; Agozie, Divine Q.Objectives. The 5G has ushered in a new age of life-changing breakthroughs and advancements due to faster speeds, greater bandwidth, and ultra-high expectancy. The study proposes a multistage approach for quantifying the dynamic factors affecting users’ adoption of 5G in emerging countries. Method. This study integrated the technology acceptance model (TAM) and unified theory of acceptance and use of technology (UTAUT) to recommend a comprehensive model that the industry–academia can adopt. In the proposed model, various core hypotheses and subhypotheses were tested by employing 510 5G users of the metro cities of India. An online questionnaire was used to collect the facts, and the data were framed in the conceptual model to test the validation using partial least squares structural equation modeling (PLS-SEM). Results. The findings suggest that users’ perceptions of adopting 5G are overwhelming in that perceived trust was discovered as a mediating enabler between behavioral intention (BI) and selected manifest. Performance expectancy (PE), effort expectancy (EE), social factors (SF), facilitating factors (FF), hedonic motivation (HM), perceived benefits (PB), price value (PV), and habit (HB). Contribution. By identifying key enablers in the suggested model, service providers may better evaluate these aspects, particularly in ensuring reliable infrastructure for 5G service stands. The study is undoubtedly a novel attempt to assist the telecom industry and policymakers in accelerating the adoption of 5G in emerging economies of Asian continents.Öğe Revisiting the pollution haven hypothesis within the context of the environmental Kuznets curve(Emerald, 2023) Bekun, Festus Victor; Gyamfi, Bright Akwasi; Etokakpan, Mfonobong Udom; Çakır, BurçinPurpose: This purpose of this study is to explore the impact of global trend of economic integration and interconnectedness which has drawn the attention of world economies and their implications on trade inflow. This trajectory has its impact, either positive/negative, on key macroeconomic indicators, to say the least on environmental sustainability, especially emerging economies. To this end, the need to explore the connection between foreign direct investment (FDI) inflow and energy consumption amidst the wave of economic globalisation is timely and pertinent for the case of Turkey. Design/methodology/approach: This study seeks to explore the interaction between the outlined variables in a carbon-income framework for annual time series data from 1970 to 2016. A series of econometrics strategies was used consisting of unit root tests to examine the stationarity properties of the highlighted series. Subsequently, Pesaran’s Bounds testing technique is used to explore the long-run equilibrium relationship between the highlighted variables in conjunction with the Johansen cointegration test. For long-run regression coefficients, Pesaran’s autoregressive distributed lag and dynamic ordinary least squares methodology are used, and innovative accounting approaches are used to explore the responsiveness of each variable on another. Findings: Empirical results validate the pollution haven hypothesis (PHH) in the long run for the case of Turkey. Thus suggesting that FDI inflow induced environmental degradation in Turkey. Additionally, this study observed that renewable energy, on the contrary, improves the quality of the environment. This study also affirms the presence of the environmental Kuznets curve phenomenon, indicating that Turkey, at its early stage of economic trajectory, emphasis is on economic growth rather than environmental quality. This suggests a need for more deliberate action(s) by the government administrators to pursue cleaner FDI inflow and energy technologies and strategies to foster a clean environment in Turkey and a cleaner ecosystem at large. Originality/value: This study is unique in its choice of variables which is in line with the United Nations Sustainable Development Goals (SDGs) agenda to be achieved by 2030 and is very limited in the extant literature. From the economic perspective, the effect of the PHH is of interest especially to ascertain the extent the interplay among the variables has on the economy of Turkey. The empirical insights on PHH hypothesis have received less documentation in the extant literature especially for emerging economy like Turkey. Thus, this study seeks to revisit this theme for Turkey with aim to presents environmentally sustainable strategies without compromise for economic growth. Thus, this study seeks to revisit this theme.
