Öğe Economic globalization and ecological impact in emerging economies in the post-COP21 agreement: A panel econometrics approach(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2024) Bekun, Festus Victor; Öztürk, İlhanGlobally, the need for ecological well-being and sustainable development attracted research and policy attention over the years. However, issues concerning the nexus between globalization and ecological safety remain contentious and unresolved. Therefore, this study contributes to the discourse by evaluating the impact of economic globalization on ecological footprints in seven emerging economies (E7) while accounting for other drivers of environmental degradation in the outlined bloc for the period of 1990– 2021. The present study leverages on panel data econometric techniques to achieve the study objectives. The findings shows that economic globalization and increase in economic activities drive a higher ecological footprint and thus reduce environmental quality in emerging economies. This study concludes that the economic progress of emerging economies and the increasing wave of their economic integration is detrimental to environmentally sustainable development. Therefore, this study recommends, among other insightful policy inferences, that the global agenda on sustainable development should be prioritized, environment-friendly integration among emerging economies should be pursued. Environmental regulations should be strictly observed by the countries in their bid for economic development and integration.Öğe Environmental consequences of economic complexities in the EU amidst a booming tourism industry: Accounting for the role of brexit and other crisis events(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2021) Adedoyin, Festus Fatai; Agboola, Phillips O.; Öztürk, İlhan; Bekun, Festus Victor; Agboola, Mary OluwatoyinThe European Union (EU) is one of the strongest, but most complex unions in the world with a competitive tourism industry. The aim of this study, therefore, is to account for economic complexity index (ECI), Brexit and other crisis episodes in the growth-energy-emissions nexus. Theoretically, the traditional Environmental Kuznets Curve (EKC) model is assessed by adopting a One-step System Generalized Method of Moment (Sys GMM) on data for 26 EU member states over the period from 1995 to 2018. For the first time, an EU-macro regional analysis is conducted with and without the UK. Empirical results reveal that an increase in tourism, real GDP per capita, and energy use across the four EU macro regions leads to increase in carbon emission. In some regions, it was observed that tourism, ECI, Brexit, and the Greece bailout have no significant impact on carbon emission. This suggests that the increase in international travel, complexity of the economy, and financial crisis do not accelerate environmental crisis in such regions. However, where such factors are statistically significant, Brexit and the Greece bailout crisis both heighten emissions. Particularly, when the UK is excluded, Brexit and the Greece bailout crisis increase and reduce emissions, respectively. The EKC hypothesis, however, holds in either scenario. Based on these empirical findings, vital policy directions are suggested for a post-Brexit EU-UK energy and environmental relations.Öğe Environmental Kuznets Curve hypothesis from lens of economic complexity index for BRICS: Evidence from second generation panel analysis(ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2022) Agozie, Divine Q.; Gyamfi, Bright Akwasi; Bekun, Festus Victor; Öztürk, İlhan; Taha, AmjadThe present study contributes to the ongoing discussion on environmental sustainability, energy efficiency for the case of Brazil, Russia, India, China, and South Africa economies by investigating the dynamic connection regarding foreign direct investment, economic complexity index, renewable energy, natural resources, urbanization, and CO2 emission for annual frequency data from 1990 to 2019. The present study employs robust econometric techniques including Augmented Mean Group with Fully Modified-Ordinary Least Squares estimators as estimation techniques. Empirical outcome shows both inverted U-Shaped and N-Shaped EKC relationship between ECI and CO2 emission. The empirical findings also lend support to the Pollution Haven Hypothesis, which suggest that foreign direct investment influx is a contributing factor to environmental degradation in Brazil, Russia, India, China, and South Africa economies. Furthermore, renewable energy and the interaction between economic complexity index and urbanization is found to have adverse impact on emission while natural resources and urbanization have positive impact on the environment. Finally, the results from the Dumitrecu and Hurlin causality reveals a bi-directional causality between economic complexity and CO2 emission. Similar causality is found between economic complexity index and urbanization and CO2 emission while a one-way causality is seen running from foreign direct investment to CO2 emission over study period. These findings encourage authorities of the investigated countries to offer a broader energy strategy on alternative energies i.e., renewables improve Brazil, Russia, India, China, and South Africa environmental quality. Furthermore, emphasis on economic strategies that foster a healthier manufacturing activity to engender environmental sustainability without compromise for economic prosperity should be pursued among the examined economies.Öğe Examining the Interaction Effect of Control of Corruption and Income Level on Environmental Quality in Africa(MDPI, ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2022) Usman, Ojonugwa; Iorember, Paul Terhemba; Öztürk, İlhan; Bekun, Festus VictorThe effects of corruption and income on environmental degradation is well established in the literature. However, little attention has been given to how the control of corruption affects the environmental quality at different levels of income. This study examines the interaction effect of the control of corruption and income on environmental quality in Africa over the period from 1996 to 2017. Using a Method of Moments Quantile Regression (MMQR) with fixed effects, the results revealed that both the control of corruption and income level increase CO2 emissions while their interaction term reduces CO2 emissions. This implies that the interaction effect of the control of corruption and income level mitigates carbon emissions. Particularly, the marginal effect of the control of corruption on CO2 emissions decreases as income level increases. Furthermore, renewable energy consumption has a negative and significant effect on CO2 emissions. The effect of foreign direct investment on CO2 emissions is positive and significant, which validates the pollution haven hypothesis. These results are heterogeneous across the quantile distribution of CO2 emissions. Based on these findings, our study suggests the need for the government and policymakers to stimulate income levels as a prerequisite for achieving sound and effective environmental policies in Africa.Öğe Explosivity and Time-Varying Granger Causality: Evidence from the Bubble Contagion Effect of COVID-19-Induced Uncertainty on Manufacturing Job Postings in the United States(MDPI, ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2022) Bekun, Festus Victor; Alhassan, Abdulkareem; Öztürk, İlhan; Gimba, Obadiah JonathanThis study evaluates the explosive behavior and Granger causality episodes in manufacturing job postings in the United States (JOBPUS) and COVID-19-induced uncertainty (COVIDEMV). This study applied the novel unit root tests with explosive behavior, and the novel time-varying Granger causality test for a sample period ranging from 1 January 2020 to 29 July 2022. Further, this study used date stamping to identify the subperiods of the explosive behavior and causality. The findings revealed that JOBPUS exhibits explosive behavior, with several episodes of exuberance (bubbles) across the sample period while COVIDEMV does not exhibit explosivity during the period. However, the results of the causality provide evidence of bidirectional causality, with several episodes between the variables. Moreover, the episodes of the explosivity and causality coincide with significant episodes in the history of the COVID-19 pandemic worldwide and in the United States particularly, such as the date when United States recorded a COVID-19-related death toll of over 100,000 people for the first time, after the presidential election, after Halloween celebrations, after the discovery and administration of COVID-19 vaccines as well as the discovery of the Delta and the Omicron variants of COVID-19. Therefore, the time-series characteristics of JOBPUS and its causal nexus with COVIDEMV largely depend on the intensity of the instability caused by the pandemics. Hence, explosivity and time-varying causal behavior should necessarily be accounted for when modelling the job market conditions in the United States, particularly during pandemic-related crises.Öğe The implications of renewable and non-renewable energy generating in Sub-Saharan Africa: The role of economic policy uncertainties(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2021) Adedoyin, Festus Fatai; Öztürk, İlhan; Agboola, Mary Oluwatoyin; Agboola, Phillips O.; Bekun, Festus VictorSub-Saharan Africa which is one of the main regions known for various sources of mineral and energy resources in the global market has experienced appreciable rates of economic expansion in the last 10 years. However, apart from the environmental consequences of generating energy, how uncertainties in the economy moderate the impact of energy generation on the environment is yet to be given desired attention. Hence, this study investigates the role of economic policy uncertainty in the energy-growth-emissions nexus for 32 countries in SubSaharan Africa over the period from 1996 to 2014. Results from one-step system-GMM show that real GDP and generation of non-renewable energy both increases CO2 emissions. However, while economic policy uncertainty also propels high levels of emissions in the region, its moderation effect on the impact of both renewable and non-renewable energy generation leads to a reduction in emissions level in the region. This suggests an urgent need for the implementation of sound macroeconomic and energy policies in Sub-Saharan Africa to safeguard the energy sector from disruptions and to mitigate the resultant impact on the degradation of the environment in the region.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 Is clean energy prosperity and technological innovation rapidly mitigating sustainable energy-development deficit in selected sub-Saharan Africa? A myth or reality(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2021) Alola, Andrew Adewale; Öztürk, İlhan; Bekun, Festus VictorUnited Nations Sustainable Development Goals (UN-SDGs) such as access to clean energy (SDG-7), responsible energy consumption (SDG-12) and sustainable economic growth revolves around the subject of human development that resonates with (SDG-8), and among others. Based on these highlights, this study examines sustainable development for the panel of selected Sub-Sahara African countries that are largely plagued with huge energy deficit (energy poverty) and setback in technological innovation. This study leverages on panel econometrics strategies to explore the hypothesized relationship between the outlined indicators for the period 2000–2016 in Sub-Saharan African countries. Empirical results show that human development index (HDI), economic expansion, access to clean energy. and technological innovation exhibits long-run equilibrium relationship. Subsequently, the finding revealed that economic expansion, access to energy and technological innovation in the sampled countries spur higher HDI indices. That is, a 1% increase in economic growth increases HDI by 0.040% and 0.017% in the short and long run respectively. Thus, we can infer that enhanced sustainable economic growth leads to higher HDI indices which encompases higher literacy rate, better income level and increase life expectancy in both short and long run. In contrary, access to clean energy in the selected blocs dampens HDI index in the short run but the effect is statistically positive (desirable) in the long run.Öğe Mirroring risk to investment within the EKC hypothesis in the United States(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 24-28 OVAL RD, LONDON NW1 7DX, ENGLAND, 2021) Alola, Andrew Adewale; Öztürk, İlhanIn reality, economic expansion cannot be paced-up enough. This account for a potential trade-off between income and environmental degradation that is expectedly feasible at a maximum level of income. On this note, the current study looked at the validity of income-environmental degradation (Environmental Kuznets Curve, EKC) hypothesis especially amidst risk to investment in the United States over the period 1984–2017. Considering that the burning of fossil fuels constitutes the largest source of Greenhouse gas (GHG) in the United States, this study employed energy carbon emissions as a proxy for environmental quality and as a dependent variable. While the study employed renewable energy production as additional explanatory variable, it implemented the Autoregressive Distributed Lag (ARDL) technique in addition to a set of cointegration techniques. Importantly, the study found that the EKC hypothesis is valid for the case of the United States but not without a non-significant trade-off of risk to investment. Additionally, renewable energy production exhibits a statistically significant and desirable impact on environmental quality in both the short and long-run. In general, the study posited that while environmental sustainability is achievable at maximum level of income, it is likely attainable at the detriment of risk to investment. Hence, this observation should trigger a potential policy mechanism that minimizes risk to investment in light of the attainment of the country’s sustainable development goals (SDGs).Öğe Modeling the dynamic linkage between financial development, energy innovation, and environmental quality: Does globalization matter?(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ, 2021) Baloch, Muhammad Awais; Öztürk, İlhan; Bekun, Festus Victor; Khan, DanishIn the modern era of the wave of globalization, financial development is leading toward a higher rate of economic expansion and promoting energy innovation around the globe. Nevertheless, environmental impact of financial development has preoccupied government officials to circumvent adverse impact on environmental quality. Thus, this paper examines the nexus between financial development, economic growth, energy innovation, and environmental pollution for the period of 1990–2017 for the panel of Organization for Economic Cooperation and Development (OECD) countries. To obtain robust and unbiased results, this study utilizes Pooled Mean Group Autoregressive Distributed Lag (PMG/ARDL) estimator that counters the issue of heterogeneity and cross-sectional dependence. Empirical evidence suggests that financial development promotes energy innovation and improves environmental quality. Globalization also has a long-term relationship with energy innovation and reduces greenhouse gas (GHG) emissions. Moreover, findings validate the environmental Kuznets curve for OECD countries in the significance of financial development, globalization, and energy innovation.Öğe Renewable and non-renewable energy policy simulations for abating emissions in a complex economy: Evidence from the novel dynamic ARDL(PERGAMON-ELSEVIER SCIENCE LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, ENGLAND, 2021) Adedoyin, Festus Fatai; Öztürk, İlhan; Bekun, Festus Victor; Agboola, Phillips O.; Agboola, Mary OluwatoyinAccording to the Economic Complexity Index, Japan was the number 1 most complex economy in the world. In addition to complexity, Japan pledges to reduce emissions by boosting cleaner energy sources. This study simulates two policies to highlight a path for Japan in achieving this ambitious energy and environmental target. The novel dynamic autoregressive distribution lag (ARDL) model and Kernel-based regularized least squares (KRLS) are adopted over panel data from 1970 to 2018. Empirical evidence from the ARDL and dynamic ARDL models shows that CO2 emissions have a significant long-term relationship with GDP per capita, renewable energy, and economic complexity index while air transport is significant in the short run. Putting it more elaborately, a unit increase in GDP per capita increase the emission by 0.84%e0.96% in the long run and 0.46%e0.48% in the short run. As regards renewable energy, a unit increase in it decrease the carbon emission by 0.07% and 0.04% in the long-run and short-run respectively. Also, an increase in the economic index diminished the emission by 0.81% in the long run. Moreover, economic complexity moderates the role of GDP in environmental degradation as it also has a significant impact on carbon emission.Öğe Structural breaks in CO2 emissions: Are they caused by climate change protests or other factors?(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 24-28 OVAL RD, LONDON NW1 7DX, ENGLAND, 2020) Adedoyin, Festus Fatai; Öztürk, İlhan; Abubakar, Isah Funtua; Kumeka, Terver Theophilus; Folarin, Oludele; Bekun, Festus VictorIn recent times, there has been increase in climate change protest across the globe. However, whether decrease in emissions is connected with climate change protest or not is yet to be documented in the literature. Consequently, the aim of this study is to fill this gap by examining ex-post detection of how climate change protests and its interconnectedness with CO2 emissions. Using the Bai and Perron (1998) structural break test, we estimate the number of breaks as well as the date of such structural breaks in CO2 emissions series for 41 countries. Our aim is to match the date of the climate change protests to those of the structural breaks. We observe that climate change protests are fairly consistent with the dates of breaks in Europe and Asia, but not in BRICS economies or US, Canada and other countries. Therefore, this method allows us to solve a gap in the energy industry related to the modelling and correct allocation of positive shocks in CO2 emissions to climate change protests.Öğe Tourism-induced pollution emission amidst energy mix: evidence from Nigeria(SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2022) Bamidele, Ruth Oluyemi; Öztürk, İlhan; Gyamfi, Bright Akwasi; Bekun, Festus VictorIn recent years, there is concerted eforts to boost the tourism industry in Nigeria, and regulatory bodies were created for the tourism industry. This study is contributing to the ongoing debate on the tourism-energy-environment literature. Thus, we explore the linkage between tourism development, energy consumption, carbon dioxide (CO2) emission, and renewable energy consumption in Nigeria for the period of 1995–2016. The present study leverages on Bounds testing to cointegration in a carbon-income function environment while incorporating renewable energy consumption to the econometric framework. Subsequently, autoregressive distributed lag methodology alongside dynamic ordinary least square (DOLS) is utilized for robustness of estimations. Empirical results give credence to the energy-induced emission hypothesis in Nigeria. This outcome is suggestive to policymakers as fossil fuel-based energy consumption deplete the quality of the environment. Similarly, the study also afrms the environmental Kuznets curve (EKC) phenomenon. The emphasis on Nigerian growth trajectory (real income level) relative to her quality of environment via the channel of economic development and energy consumption from fossil-fuel source is indicated. On the other hand, renewable energy consumption in Nigeria shows signifcant ability to reduce emission level in Nigeria. This result is insightful, which implies that environmental quality is not threatened with an increase in tourist arrivals, hence tourism does not degrade the environment but is sustainable to the environment. Interesting and laudable for stakeholders’ international tourism arrival did not deplete the quality of the environment. The plausible explanation is attributed to the scale of tourism in Nigeria which at the moment is still low or much more there is caution/awareness on ecotourism for sustainable environment.
