Öğe The anthropogenic consequences of energy consumption in E7 economies: Juxtaposing roles of renewable, coal, nuclear, oil and gas energy: Evidence from panel quantile method(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2021) Gyamfi, Bright Akwasi; Adedoyin, Festus Fatai; Bein, Murad A.; Bekun, Festus Victor; Agozie, Divine Q.The emerging industrialized seven (E7) economies are not excluded from the global warming issues which is a major problem for most economies. The E7 member countries have partaken in policies to mitigate against global warming in terms of decoupling CO2 emission from economic growth trajectory in the highlighted economies. It is on this premise that the present study is motivated to consider the connection among economic growth, pollutant emissions, coal rent while accounting for the role of other co-variates such as CO2 damage and energy from a nuclear energy source, oil gas energy between 1990 and 2016 on an annual frequency. This study adopts the use of panel ordinary least squares alongside panel quantile regression to explore the coal rent-energy and environment nexus. The empirical result shows a positive and significant effect of both real GDP and coal rent on CO2 emissions. More precisely, a 1% increase in GDP growth increases pollution emission by 0.400% while for coal rent, an increase in coal consumption dampens environmental quality by 0.088% as reported by the panel regression which is resonated by the quantile regression estimations at different tails of the data. Nevertheless, we observe that 0.95 percentile GDP growth strongly contributes to environmental pollution while at the median tail i.e. 0.5 percentile renewable energy consumption dampens the adverse effect of environmental degradation. Additionally, renewable energy, on the other hand, was found a negative and significant impact on CO2 emissions in E7 countries as a 1% increase in renewable energy consumption improves environmental quality by 0.588% Moreover, the estimated results indicate that regulation of coal consumption through the rent in addition to the cost of carbon damage will further increase the CO2 emissions in E7 countries. This study implies that putting stringent regulations on coal consumption as it concerns the increasing cost of carbon damage will not be of help to environmental sustainability within the E7 economies. The adoption of renewable energy consumption, nuclear energy, oil energy will reduce CO2 emissions in E7 countries. Thus, suggesting a paradigm shift for low-carbon energy sources which are more environmentally friendly.Öğe Assessment of environmental implications of energy consumption towards sustainable development in G7 countries(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2021) Gyamfi, Bright Akwasi; Bein, Murad A.; Bekun, Festus Victor; Yaw, Sarpong Steve; Vo, Xuan VinhFollowing universal debate for energy sources and sustainable development across the globe, with its far-reaching implications on the environment, this crusade aligns with the United Nations Sustainable Development Goals (UN-SDGs). The study variables are based on the SDGs-7, 8, and 13 that highlights access to clean energy, sustainable economic growth and mitigation of climate change issues. Awareness of environmental sustainability has received much consideration because of the hazards associated with climate change issues in recent times. Studies on environmental quality and pollution emissions (CO2) are becoming increasingly interesting. It is reported that human activities and increasing economic issues resolve environmental-related challenges. In the light of this, we assess how employment moderates energy consumption and climate change for G7 countries. We utilise panel co-integration and long-run regression using dynamic ordinary and fully modified ordinary least squares to institute the magnitude of long-run elasticity among the outlined variables. Panel heterogeneous techniques are used to detect the direction of causality for the annual data from 1990 to 2016. The empirical result shows a clear significant correlation between variables and the long-run relationship between pollutant releases and energy utilisation, employment and real output. The study finds an inverse relationship between trade and pollutant emissions, thus suggesting that openness trade mitigates against environmental degradation in the sampled blocs. The causality analysis reveals a bidirectional causality between emissions and employment and a unidirectional causality between emissions, real GDP, energy utilisation and trade. These results have far-reaching outcomes on environmental fronts and economic growth highlighted in this study.Öğe Bitcoin’s Reaction to the Federal Reserve’s Announcements and Stimulus Measures, the Equity Market, and Economic Policy Uncertainty: Evidence during the COVID-19 Pandemic(CRC Press, 2024) Bein, Murad A.; Gyamfi, Bright Akwasi; Bekun, Festus Victor; Taha, AmjadThe COVID-19 pandemic is still underway, which means that the crisis’s full extent cannot yet be known. Nevertheless, investigations into the economic effects of the pandemic and its impact on the financial markets have begun. Since the onset of the COVID-19 crisis, the stock markets in both developing and developed economies and the international crude oil and currency markets have experienced the worst volatility on record. During periods of uncertainty, investors typically attempt to reduce their exposure or diversify their investments and search for safer assets. Recently, there has been an increase in the debate regarding whether Bitcoin can serve as a haven during periods of market turmoil. While regular currencies are guaranteed by the governments or organizations that issue them, Bitcoin, as a digital currency, is not guaranteed by anybody (Weber 2016). © 2024 Andrew Adewale Alola, Festus Victor Bekun and Uju Violet Alola.Öğe Does agricultural development induce environmental pollution in E7? A myth or reality(SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2021) Adedoyin, Festus Fatai; Bein, Murad A.; Gyamfi, Bright Akwasi; Bekun, Festus VictorEnvironmental degradation caused by various human activities has been a subject of attention over the globe. There is a concern on how to maintain a clean environment and at the same time achieve optimum production of food and non-food products amidst global energy demand. To this end, this study examines the impact of agricultural development, energy use, and economic growth on CO2 emissions in the emerging seven countries that comprises China, India, Brazil, Mexico, Russia, Indonesia, and Turkey for the annual time frequency from 1990 to 2016. The study uses a battery of econometrics techniques for soundness of analysis the consist of pooled mean group autoregressive distributed lag methodology, dynamic ordinary least squares, and fully modified ordinary least squares as estimation techniques alongside Dumitrescu and Hurlin causality test for the direction of causality analysis. Empirical results revealed that value-added agriculture and economic growth are drivers of CO2 emission in the E7 countries, and the rise in renewable energy causes a reduction in CO2 emissions, while in the short run, economic growth has a positive impact on emissions in the focus countries. Causality analysis shows that there is a feedback causality between economic growth and emissions, between value-added agriculture and energy usage, between emission and value-added agriculture, and between economic growth and agricultural development. Furthermore, energy use does not cause emissions directly; it causes economic growth and value-added agriculture which causes emissions. This position aligns with the advocacy of the United Nations Sustainable Development Goal (UN-SDG) Targets 7 and 13 of clean energy access and mitigation of climate changes issues.Öğe Environmental implications of N-shaped environmental Kuznets curve for E7 countries(SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2021) Gyamfi, Bright Akwasi; Adedoyin, Festus Fatai; Bein, Murad A.; Bekun, Festus VictorThe environmental Kuznets curve (EKC) hypothesis is of great importance to understanding the relationship between economic activity and environmental degradation. Given the current wave of climate change and environmental crisis traced to rising environmental pollution from economic activities, it has become important to investigate the impact of economic expansion on the environment especially in the emerging-7 countries that are responsible for a large amount of global economic activity. This study investigates the N-shaped EKC for the E-7 countries using data spanning the period 1995–2018. The study employs the use of PMG-ARDL estimator and heterogeneous causality tests to establish the long run and short run and direction of causality respectively regarding the variables of interest. According to study empirical results, the long-run results fail to confirm the presence of an N-shaped EKC in the emerging 7 countries but rather confirms the existence of an inverted U-shaped EKC in the study countries. While renewable energy and non-renewable energy have a positive and significant relationship with CO2 emissions, short run results show that there is no significant relationship between economic expansion, renewable energy, non-renewable energy and CO2 emissions. Causality tests showed a bi-directional causality between GDP- and GDP-squared and a uni-directional causality from CO2 emissions to GDP-cubed, non-renewable energy and CO2 emissions, renewable energy, and CO2 emissions. The study suggests increased use of renewable energy to mitigate pollutant emissions in the E-7 countries.Öğe How does energy investment affect the energy utilization-growth-tourism nexus? Evidence from E7 Countries(Sage Publications Ltd, 2022) Gyamfi, Bright Akwasi; Bein, Murad A.; Adedoyin, Festus Fatai; Bekun, Festus VictorTourism is an important driver of economic growth for several countries in the world. However, the rise in tourism activities has raised concerns regarding emissions resulting from tourist activities such as transportation as well as the consequent effect on the quality of the environment. Hence, this study examines the impact of tourism and other factors such as investments, energy utilization and economic growth on carbondioxide (CO2) emission in the emerging industrialized seven countries namely (China, India, Brazil, Mexico, Russia, Indonesia and Turkey) for the period 2000 to 2018. The study uses the Pool Mean Group Autoregressive Distributed Lag (PMG-ARDL), ordinal least square (OLS), dynamic ordinals least square (DOLS) and fully modified least square (FMOLS) estimators as well as Dumitrescu and Hurlin Causality Test. Long run regression estimates reveal that a increase in tourism activities lower carbondioxide emissions in the E7 countries which can be traced to the adoption of environmentally friendly tourism. Furthermore, investment in energy and economic growth, the majority of the regression results point that both factors lower carbondioxide emissions in the emerging seven (E7) countries while energy consumption is a driver of CO2 emissions in the E7 countries. The study suggests that the implementation of environmentally friendly tourism be sustained to continually improve the quality of the natural environment in the blocs. Similarly, strict regulations of economic activities in line with the protection of the environment are advised while the use of renewable energy is needed to reduce emissions in the E7 countries.Öğe Investigating the nexus between hydroelectricity energy, renewable energy, nonrenewable energy consumption on output: evidence from E7 countries(SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2020) Gyamfi, Bright Akwasi; Bein, Murad A.; Bekun, Festus VictorThe transition of most economies especially heavily industrialized nations like China, Turkey, Russia, India, Indonesia, Brazil, and Mexico fondly known as E7 are fast emerging economies with its impact on economic growth and ecosystem. On the above highlight, the present study explores the dynamic interaction between hydroelectricity energy, renewable energy consumption, nonrenewable energy consumption on economic growth over annual time frequency data from 1990 to 2018. To this end, Kao co-integration technique is adopted in conjunction with panel ordinary least squares, dynamic ordinary least squares, and fully modified ordinary least square estimators over the identified blocs while the heterogeneous causality test of Dumitrescu and Hurlin is employed to detect the direction of causality among the variables. Empirical result shows long-run analysis reveals long-run equilibrium relationship between the examined variables. Furthermore, a one-way causality relationship is observed between economic growth and nonrenewable energy, economic growth and renewable energy, and economic growth and pollutant emission. The present study identifies a U-shaped pattern among nonrenewable energy consumption and economic growth in the long-run. These findings suggest that as economic growth increases, there is less strengthening of energy from the nonrenewable energy consumption hence, portentous deterioration in nonrenewable usage while authenticating the proficiency of nonrenewable energy consumption in the E7 countries. Further policy prescriptions are rendered in the concluding section.Öğe Investigating the pollution haven hypothesis in oil and non-oil sub-Saharan Africa countries: Evidence from quantile regression technique(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2021) Gyamfi, Bright Akwasi; Bein, Murad A.; Udemba, Edmund Ntom; Bekun, Festus VictorThe deepening of global trade flows and world interconnectedness has its implications on several macroeconomic indices that stretches, to say the least environmental consequences. To this end, this study explores the dynamic interaction between energy consumption (renewable and non-renewable), foreign direct investment, carbon dioxide emission, real income and urbanization for both oil and non-oil countries for annual period from 1990 to 2016 in a carbon-income framework. To examine the nature of relationship between the outlined variables, we rely on a balanced panel econometrics analysis alongside panel quantile regression. Empirical analysis affirms the pollution haven hypothesis for both oil and non-oil countries under consideration. This suggests that foreign direct investment inflow has a detrimental effect on the host country. This is instructive to stakeholders and government officials. Further empirical results show that conventional energy from (fossil-fuel), urban population dampens environmental quality in the examined regions. However, renewable energy shows strong strength to improve environmental quality. This implies that renewables energy serves as a panacea to environmental sustainability target in both oil and non-oil dependent countries. Finally, these outcomes suggest the need to pursue low-carbon strategies for a cleaner and friendly environment.Öğe An investigation into the anthropogenic effect of biomass energy utilization and economic sustainability on environmental degradation in E7 economies(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2021) Gyamfi, Bright Akwasi; Öztürk, İlhan; Bein, Murad A.; Bekun, Festus VictorAbstract: Inspired by the Sustainable Development Goals (SDGs), this study focuses on the need for responsible and clean energy consumption, climate change mitigation, and sustainable economic growth. To this end, the study investigates the connection between biomass energy consumption, real GDP, investment in the energy sector, and CO2 emissions in the emerging (E7) countries – China, India, Brazil, Mexico, the Russian Federation, Indonesia and Turkey – for the period 2000–2018. The study uses a battery of techniques, namely Pooled Mean Group-autoregressive distributed lag, ordinary least square, dynamic ordinary least square, Fully Modified Ordinary Least Squares (PMG-ARDL, OLS, DOLS FMOLS) and causality estimators, to measure the robustness of the conceptualized relationship among the variables of interest. Empirical results show that conventional energy from fossil fuel sources is a driver of CO2 emissions within the E7 economies. On the other hand, biomass energy consumption and investments in the energy sector decrease CO2 emissions. Furthermore, a feedback causality relationship between biomass energy consumption and CO2 emissions is observed. Similarly, a feedback causality relationship is seen between economic growth and biomass energy consumption. Our study’s empirical findings reveal that biomass energy consumption mitigated CO2 emissions in the E7 economies that were examined, suggesting the pivotal role for biomass energy consumption in creating an ecofriendly environment and environmental sustainability. This requires investment from the private sector, stakeholders, and government administrators in cleaner energy technologies initiatives like biomass.Öğe The Moderating Role of Employment in an Environmental Kuznets Curve Framework Revisited in G7 Countries(Univ Pasundan, 2020) Gyamfi, Bright Akwasi; Bein, Murad A.; Ozturk, Ilhan; Bekun, Festus VictorAnthropogenic activities have resulted in environmental concerns due to the global consciousness for mitigating climate change issues. This awareness is emphasized in the sustainable development goals contained in the seventh and 13th targets. The study investigates the nexus between energy and growth while considering the moderating role of employment and its interaction with energy consumption in G7 countries for the period of 1980-2018. To achieve this objective, a carbon-income function is fitted to ameliorate the problems related to omitted variable bias. Empirical results indicate that all outlined variables are cointegrated over the investigated period, as reported by the Kao cointegration test. The study further validates the environmental Kuznets curve (EKC) hypothesis in the short-run. With emphasis on economic growth relative to environmental quality while in the long run, there is no statistical evidence in support of the EKC phenomenon. Furthermore, a 1% increase in energy consumption increases pollutant emission in the long run by 3.80%. Similarly, a positive elastic relationship is observed between trade and environmental degradation. This outcome is demonstrated in the causality results, which reveal a one-way causality running from trade to pollutant emission. These findings provide insights that can help policy formulations, including decoupling economic growth from pollutant emission and the need to adopt cleaner and eco-friendly technologies.Öğe Renewable energy consumption a panacea for Sustainable economic growth: panel causality analysis for African blocs(TAYLOR & FRANCIS INC, 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106, 2022) Steve, Yaw Sarpong; Bein, Murad A.; Gyamfi, Bright Akwasi; Bekun, Festus Victor; Uzuner, GizemThe issue of increased renewable energy consumption has been widely debated, and this has become a central energy policy concern for developing and developed countries. The existing literature provides evidence that there is a positive relationship between energy consumption and economic growth in developed economies. However, findings in respect of developing/emerging economies remain inconclusive. Thus, this paper aims to investigate the impact on renewable energy consumption on economic growth by controlling other macroeconomic variables for regions of Sub-Saharan Africa (East, Central and West) covering the 1990–2018 sample period. For this purpose, common correlated effects mean group estimator (CCEMG) and Dumitrescu-Hurlin Granger causality test approach are used to consider both cross-sectional dependency and cross-country heterogeneity across countries. The CCEMG result indicates that an increase in renewable energy consumption led to reduction in economic growth even when the sample is analyzed based on geographical locations as East, West, and Central Africa. Granger causality results validate the feedback hypothesis for only Central Africa; the growth hypothesis is supported for East and West Africa. The empirical results suggest that energy planners, governments, and policy makers must act together to increase the renewable energy consumption share in her energy mix to promote economic growth for regions of Sub-Saharan Africa.Öğe Renewable energy, economic globalization and foreign direct investment linkage for sustainable development in the E7 economies: revisiting the pollution haven hypothesis(John Wiley and Sons Inc, 2022) Gyamfi, Bright Akwasi; Bein, Murad A.; Udemba, Edmund Ntom; Bekun, Festus VictorThis present study is motivated by the United Nations Sustainable Development Goals (UN-SDGs) that concerns pertinent issues that comprises environmental sustainability (SDG-13), sustainable development (SGD-8), and responsible consumption (SDG-11), among others. To this end, this study examines the long-run and causality linkage between renewable and non-renewable energy, foreign direct investment, and economic globalisation in a carbon-income framework by use of both carbon dioxide emission and ecological footprint as a determinant for environmental degradation for E7 countries. Furthermore, a series of panel econometrics panel tests in conjunction with quantile regression is used to explore the relationship between the outlined variables for annual frequency data from 1990 to 2016. Empirical results trace a long-run equilibrium relationship among the highlighted variables as reported by Westerlund (2007). Additionally, this study gives credence and validates the pollution haven for the emerging (E7) countries examined, thus, implying the detrimental effect of foreign direct investment (FDI) on quality of environment in E7 economies. Interestingly, we observe that investment in renewable energy consumption will improve environmental quality. This outcome resonates with the advocacy of UN-SDGs-7, 11, 12, and 13, where emphasis is placed on responsible energy consumption (renewables), access to clean energy, and climate change mitigation. Conclusively, these revelations suggest the chase for adoption of low-carbon development technologies and strategies in E7 countries. © 2021 John Wiley & Sons Ltd.Öğe To what extent are pollutant emission intensified by international tourist arrivals? Starling evidence from G7 Countries(SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2022) Gyamfi, Bright Akwasi; Bein, Murad A.; Adedoyin, Festus Fatai; Bekun, Festus VictorA large volume of environmental science and pollution research has focused on the contributions of various forms of energy consumption to emissions. However, little attention is given to the impact of human activities such as tourism. Hence, this study investigates the impact of tourist arrivals, energy use, and economic growth on CO2 emissions in the G7 countries for the period 1995–2018. The study employed the use of dynamic panel estimations, namely dynamic ordinary least square, fully modifed ordinary least squares and panel pooled mean group-autoregressive distributed lag model (PMG-ARDL) estimation techniques to establish long-run and short-run relationships between the study variable of interest, while the Dumitrescu Hurlin non-causality test was used to test for causality direction among the variables outlined. Empirical fndings from the regression revealed that economic growth, tourism and energy use are strong drivers of emission levels in the G7 bloc, while the causality analysis revealed that there is unidirectional causality from CO2 to energy use, CO2 to economic growth (GDP) and GDP to tourist arrivals. These outcomes imply that tourism, energy use and economic growth have no direct efect on emissions, but rather emissions predict economic growth and energy use. Furthermore, tourist arrivals predict energy use; economic growth predicts tourism. Overall based on the study of empirical outcomes, we suggest that to achieve more signifcant results in reducing emissions, governments of the G7 countries should continue to emphasize green tourism as well as increase the share of renewable energy in their regional energy mix. More policy direction was outlined in the concluding section of this study.Öğe Unlocking the investment impact of biomass energy utilization on environmental degradation for an isolated island(Emerald Group Publishing Ltd, 2022) Gyamfi, Bright Akwasi; Agozie, Divine Q.; Bein, Murad A.; Bekun, Festus Victor; Adedoyin, Festus FataiPurpose Discussions on environment-friendly production connected with the concerns of growing biomass emissions have gained much attention. In this regard, this study aims to explore the issue of biomass energy consumption and its related emission effects on the economic and environmental well-being of the economy of Cyprus. Design/methodology/approach This study sources time series data on specific variables from the Global Material Flow and the World Bank's World Development Indicators (WDI, 2020) between 1990 and 2016. The Robust least square (ROB-L-2) in conjunction with Pesaran autoregressive distributed lag (ARDL) methodology analysis techniques was used in addition to the Granger causality tests to examine the direction of causality flow between the variables under consideration. Findings The results indicate that biomass energy usage in the long run reduces pollution and negatively correlates with CO2 emissions level. Also, the decline of emission is influenced by increased foreign direct investment (FDI), thus, activities of foreign investors contribute to combating emission in the country. According to empirical results, non-renewable energy consumption showed both positive and negative influences on increased emission level, whereas economic growth is increasing carbon dioxide emission for the case of Cyprus. Originality/value This study applies current reliable data that offers renewed insights and sheds light on the state of affairs on biomass utilization from a developing country perspective. Additionally, it extends the discourse on the impact of biomass utilization on CO2 emissions by considering the impact of FDI, trade flow and energy consumption in a carbon-income function built on the liner version of the environmental Kuznets curve hypothesis. Although this is by no means exhaustive, the study pioneers the discourse on how FDI with biomass utilization among other relevant variables influences carbon dioxide emission.
