Using a panel data set of 189 countries by employing dynamic models OLS, fixed effect, random effect and generalized method of moments (GMM) estimators. The study revisits the relationship between institutional quality and financial development in developing and emerging countries. This study is ever the first comprehensive and wide-ranging that categorizes the countries into developing and emerging countries using multiple dynamic approaches. Experimental findings of the study are based on GMM, which indicates that better institutions are important for financial development, specifically political stability, control of corruption and regulatory quality positively affect financial development in the global panel of the study. Rule of law negatively affects financial development, which reveals that in most of the global countries, the rule of law is very feeble. Control of corruption index is positively effecting financial development in emerging and global panel which indicates that most of the countries have reduced corruption to low level. The current study also found that emerging countries have reduced corruption, but other institutional indicators are found to be insignificant. The overall result concludes that good quality institutions are the main drivers of financial development and it stimulates financial development. The present study suggests that developing and emerging countries should focus to improve the institutional quality by re-examining the rules of law, government effectiveness and voice accountability institutional factors to make it better.

The exceptional rise in overall economic activities has deteriorated environmental sustainability around the world. However, countries around the globe are implementing strategies for reaching the global climate objective. For this purpose, OECD countries committed many efforts, although their pledges and results are not parallel to the level of the Paris Agreement’s ambition. This study examines the impact of eco-innovation, environmental taxes, and renewable energy consumption on the environmental performance of selected OECD countries over the period of 2006 to 2020. This study uses the generalized method of moments (GMM) and instrumental variables 2 stage least square (2SLS) methods. For robustness checks, this study uses a quantile regression approach. We conclude that an increase in the adoption of renewable energy and green innovation has a statistically significant impact on controlling CO2 emissions. Moreover, the empirical model is expanded by incorporating environmental taxes as an explanatory variable. The expanded model showed that the imposition of environmental taxes has a detrimental impact on the reduction of CO2 emissions. Moreover, on the contrary, an increase in economic activities, measured by GDP, is responsible for rising CO2 emissions in OECD countries. In light of the results we obtained, policy recommendations are provided.

Increased demands for infrastructure, water, electricity, and different natural assets have triggered land erosion, climate change, and pollution increase and deterioration in biodiversity. The purpose of this research is to look at how economic performance, tourism, renewable energy, and energy efficiency affect carbon emissions in the emerging economies of BRICS during 1990–2021. Using panel estimation approaches, the empirical outcomes validate the longer-run equilibrium connection between the components of the model. Using a nonparametric estimator, the study found that economic performance is the significant driver of higher emissions levels in the sample countries. In contrast, tourism, energy efficiency, and renewable energy substantially reduce emissions levels and improve environmental sustainability. The estimated results have been found robust, and the feedback effect is found valid between repressors and carbon emissions. This study further suggests that investment in research and development, improvement in energy-efficient tools and equipment utilization, and enhanced renewable energy output are the key policy efforts for ensuring environmental sustainability.
