This study investigates the relationship between environmental policy stringency and financial development across 40 countries from 1990 to 2021. Using the Environmental Policy Stringency Index (EPSI) to measure environmental regulations’ rigour, we explore how these policies impact financial development, particularly focusing on financial institutions and markets. The analysis employs Ordinary Least Squares (OLS) and Fixed Effects (FE) models to capture the dynamic interactions between environmental policies and financial systems. Our findings indicate that stringent environmental policies have a positive and significant impact on financial development, mainly through enhancing financial market depth and efficiency. However, the results also reveal that financial institutions may face challenges under stringent regulations, particularly in terms of reduced access to financial services. These findings contribute to the ongoing dialogue on the economic implications of environmental policies, offering valuable insights for policymakers aiming to balance environmental sustainability with financial development.

This paper aims to examine the impact of natural disasters on banking stability across different levels of economic development. Utilizing bank-level data from 1242 banks in 72 countries, combined with natural disaster data from the Center for Research on the Epidemiology of Disasters, we contribute to the literature in three ways. Firstly, we directly assess the influence of natural disasters on banking stability. Secondly, we focus on bank-level data instead of country-level data. Thirdly, we expand on existing research by using different thresholds for the total number of people affected to population ratio, surpassing the previously suggested threshold of 0.5%. Our panel regression analysis with banks and year-fixed effects reveals that natural disasters significantly affect bank stability, particularly in middle- and low-income countries. These effects are robust across alternative measures and estimations, leading to higher non-performing loans, lower return on assets, and decreased capital and return on equity ratios, indicating a negative impact on bank performance.

This study investigates the relationship between capital intensity, debt financing, and profitability in non-financial firms in Oman over the period 2012–2022. Using a robust panel dataset of 76 firms, the research explores how capital structure dynamics influence firm performance across different firm sizes and industries. The findings reveal that capital intensity significantly enhances profitability, and debt financing further strengthens this effect, with variations observed across firm size and sector. The analysis also identifies a non-linear (concave) relationship between capital intensity and profitability, indicating that while moderate capital investment improves firm performance, excessive capital accumulation may lead to diminishing returns. Larger firms, with better access to financial resources, exhibit a stronger positive relationship between debt financing and profitability, while smaller firms face more challenges due to limited access to capital. Industry-specific results indicate that capital-intensive sectors, such as Energy and Industrials, demonstrate a more pronounced effect of capital intensity on profitability compared to less capital-intensive sectors. The study also incorporates the effects of the COVID-19 pandemic, showing its significant influence on firm performance, particularly in sectors with high debt exposure. By integrating non-linear effects, firm size, industry heterogeneity, and pandemic shocks, this study provides novel insights into capital structure management in emerging economies, offering implications for both corporate decision-makers and policymakers aiming to enhance financial access and optimize debt strategies across sectors.
