This research investigates the potential influence of extreme exchange rate asymmetry on export commerce using the instance of leading oil and non-oil exporting African economies, namely Nigeria, Ghana, Congo, Gabon, Algeria, and Morocco, within the context of MANTARDL. In addition, the analysis disentangled the positive (appreciation) and negative (depreciation) components of the exchange rate to explore if exchange rate considerations show a differential effect on the export trade. The findings for the six countries are different depending on whether the currency rate is flexible, fixed, or managed. According to MATNARDL's results, an inverted J-curve may be seen in both Nigeria and Ghana. As an additional note, (minor, moderate and major) asymmetries in exchange rate modeling nexus in oil-exporting countries in the African continent should not be neglected.

At the heart of the EU cohesion policy and the European Green deal lies the underlying sub-goals not limited to; financing the transition, promoting economic well-being of regions, take everyone along, achieving climate neutrality and a zero pollution Europe which the small and medium enterprises positions as the perfect conduit to achieve the aforementioned sub-goals in the case of Europe. Our study seeks to investigate if credit flowing from private sector units and government-owned enterprises to SMEs guarantees inclusive growth and environmental sustainability in EU-27 member states using data collected from OECD Stat. Database and the World Bank database from 2006 to 2019. Findings from the econometric analysis shows that SMEs activities is a significant and positive predictor of environmental pollution in the EU. In the case of inclusive growth countries cohort in the EU, both credit flowing from private sector funding institutions and government-owned enterprises to SMEs enhances a positive SME growth impact on environmental sustainability. In the case of non-inclusive growth countries cohort in the EU, credit flowing from private sector to SMEs enhances the positive impact of SME growth on environmental sustainability while credit flowing from government-owned enterprises to SMEs intensify the negative impact of SME growth on environmental sustainability., Competing Interests: The author declares no competing interests., (©2023PublishedbyElsevierLtd.)

In order to shed empirical light on the impact of the multi-dimensional decomposition of financial development indicators on renewable energy usage, this study investigates the threshold effect of political conflict on finance-energy dynamics in Africa. The research output relies on a panel of 46 African nations from 2010 to 2020, using IV-GMM estimators that are robust to cross-sectional dependence and allow for heterogeneous slope coefficients. The results of direct, indirect, and threshold equations show that i.) Financial development indicators spur renewable energy consumption, while political conflict drags it. ii.) There is a threshold at which financial development could spur renewable energy in some regions of Africa, and the tendency of financial development to maintain such capacity is conditioned on the accessibility of financial facilities and political conflict/stability within a specific range of threshold values. iii.) the threshold level assessment shows that 11 countries in the panel, including Botswana, Mauritius, Cape Verde, Namibia, Seychelles, Zambia, Sao Tome and Principe, Gabon, Ghana and Benin Rep., are above the threshold level of political conflict in Africa. From a policy angle, driving up renewable energy consumption in Africa requires the government to provide enabling safety net environment for the diversification of finance options targeting innovative shifts away from traditional energy sources to the expansion of alternative renewable energy ventures., Competing Interests: The authors declare no conflict of interest., (© 2023 The Authors.)

The increasing human activities amidst competition for resources across the globe has made environmental challenges an ongoing classic problem, thus prompting policymakers to continually seek effective solution while ensuring sustainable development. With the wide coverage of the relevance of the double dividend hypothesis in explaining the co-benefit of environmental tax, there is a dearth of evidence in the literature to suggest that environmental tax offers green dividends for both the environment and agricultural practice in the European countries. As such, this study employed the more recent Method of Moments Quantile Regression (MMQR) alongside other approaches for Europe's largest agrarian economies (France, Germany, Italy, and Spain) over the annual period 1995-2020. The investigation affirms the validity of the co-benefit of environmental tax as far as environmental sustainability and value-added to agriculture are concerned in this panel of 'Big Four' economies, thus motivating the countries to relentlessly pursue the carbon-neutral 2050 target. Moreover, the study aligns with the expectation that renewable energy utilization and population density are desirable factors for achieving a carbon-neutral target. Lastly, the findings suggest that environmental quality is attainable in the panel, especially as increasing income surpasses a certain threshold, thus validating the environmental Kuznets curve hypothesis. Above all, the findings provide timely policy insight that accommodates both the environmental sustainability and food security framework of the European Union. The policy options relevant in light of the study's conclusions include that the decision makers in the selected agrarian economies should ramp up energy transition opportunities through a resilient environmental tax system that incentives availability of credit and investment financing in the agriculture sector., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 The Authors.

Based on the commitment to improve environmental quality across European Union under the United Nations' Sustainable Development Goals and varying national goals, this study investigates the dynamic linkages between bureaucracy, socioeconomic factors, conventional fossil fuel energy consumption vis-à-vis aggregate fossil and disaggregate fossil (oil, coal, and gas) fuels and environmental quality in the panel of selected 25-EU nations for the period 1990-2017. The study employs relevant second-generation empirical method and unearth the following results: (1) inverted environmental Kuznets curve was validated while fossil fuel consumption has a deteriorating impact on environmental performance due to its positive effect on carbon emission; (2) fossil fuel energy consumption (both aggregate and it components) exerts a dampening impact on environmental performance due to its positive effect on carbon emission; (3) that direct effect of bureaucracy and socioeconomic factors promote environmental quality but the degree or magnitude of influence is significantly different between bureaucratic system and socioeconomic factor, and (4) the moderating or indirect impact of bureaucracy, socioeconomic on the environment via fossil fuel energy consumption is observed and significantly different across the model specification. Moreover, the result reveals a unidirectional causal relationship flows from GDP per capita, bureaucracy and socioeconomic factors to carbon emission, while bi-directional relationships between oil, gas and carbon emission are established. In policy direction, the study therefore recommend that the European Union member countries should further explore the opportunities in clean energy development in order to ameliorate the continent's environmental concerns. Furthermore, in the quest to scale up the bloc's energy transition, significant improvement in the countries' bureaucracy establishment and socioeconomic conditions could hasten the energy transition and efficiency policy while improving the environmental sustainability drive., (Copyright © 2022 The Authors.
