This study investigates the impact of environmental attention on cryptocurrency market volatility by introducing the Crypto Environmental Attention Index (CEAI), a new metric inspired by Wang et al. (2022) and constructed using daily web search data. Environmental concerns can significantly impact the popularity and volatility of cryptocurrencies, influencing risk perceptions, and shaping market dynamics. Using vector autoregression (VAR), vector error correction models (VECM), and Granger causality tests on data from 2014 to 2022, the study finds that Ethereum's volatility is strongly influenced by the CEAI in both the short and long‐term, whereas Bitcoin volatility has a short‐term unidirectional effect on environmental attention and a bidirectional relationship in the long term. This study is situated within a broader economic framework of sustainable finance, the transition to greener blockchain technologies, and regulatory responses to environmental issues. It offers actionable insights for risk management, policy formulation, and cryptocurrency valuation using environmental, social, and governance (ESG) criteria.

Purpose: In this study, we aim to define a new ecological financial pecking order. We examine how SMEs' adherence to the environment in the Mediterranean region is impacted by their financial resources and how women Entrepreneurship could play a moderating role in this relationship. Design/methodology/approach: Our data are pooled cross-sectional firm level data across 14 Mediterranean countries, with a total of 5,949 observations over the period from 2018 to 2020. We look into the moderating influence of SMEs’ female ownership on the financial sources-environmental engagement link using GLS estimations. To reach our aim we focus on seven funding sources and develop a green engagement construct using JCA. Besides, we distinguish between the least and most environmentally engaged companies in the EU and its neighborhood and compare the different interactions and possible moderations. Findings: Results show that government subsidies foster environmental engagement, followed by supplier credits with a less significant positive impact. The bank credits have the least significant beneficial influence, while non-bank financial institutions have a non-significant effect. We underline that environmental engagements are hindered by the other funds, issued bonds and internal funds. Research limitations/implications: SMEs in the Mediterranean region, particularly the less environmentally conscious, require strong legal frameworks to enforce environmental responsibility and raise awareness. Integrating less environmentally committed EU SMEs into state subsidy strategies is a chance to improve environmental responsibility in the region. Originality/value: To our knowledge, there are no prior studies that present a detailed financial structure and environmental management investigation for SMEs within the Mediterranean region while considering the moderating effect of women's entrepreneurship.

This study delves into the influence of CEO gender on climate change commitment within SMEs in the Mediterranean region. Utilizing data from the sixth wave of the BEEPS survey (2018–2020), we explore the mediating role of environmental regulation perception in this context. Our findings align with social role theory, indicating that women demonstrate heightened ecological and communal behavior, driven by their perception of environmental regulations. We reveal a full mediation link within the EU Mediterranean region, where environmental regulation perception explains women's commitment to environmental causes. However, in the EU neighborhood, we identify a direct significant effect of CEO gender on SMEs' engagement with climate change, particularly in terms of controlling CO₂ emissions. Our study sheds light on the limited presence of women in top management positions in the Mediterranean region. Additionally, we highlight the scarcity of environmental regulations for SMEs in the EU neighborhood, with the perception of these regulations as barriers hindering proactive climate change strategies. Therefore, governmental authorities need to develop more stringent environmental regulations while taking into account the financial capacities of SMEs. Providing ecological business education before implementing new regulations could also be beneficial. The study carries significant managerial and social implications, emphasizing the necessity of diverse leadership to promote sustainability and underscoring the importance of tailored regulatory initiatives for effective climate action.

Purpose: This study investigates how bank competition affects financial stability and whether government intervention contributes to shaping this relationship in North African countries.Design/methodology/approach: A review of the literature on the subject was conducted, combined with an empirical analysis that used a two-step system generalized method of moments (GMM) and a sample of 45 banks operating in North African countries over the period 2005–2019.Findings: The findings reveal a quadratic relationship between competition and banking stability in North African countries. Competition–stability view and competition–fragility view could be applied at the same time for North African banks. Additionally, in this context, results highlight a negative impact of government intervention on financial stability in a competitive financial sector. North African banks operating in a high government intervention quality environment tend to engage in high-risk investments. Robustness checks with alternative measures of competition and banking stability also show consistent results.Originality/value: To the authors’ knowledge, this is the first time that the North African context has been explored to determine the role of the quality of government intervention in the relationship between competition and banking system fragility. This paper seeks to cover the shadow field in existing literature through further new information. Thus, it contributes to the emerging market banking literature by showing that both high and low levels of competition can improve financial stability in North African countries. Moreover, it expands its contribution by displaying the moderator effect of intervention quality on the bank competition–stability relationship.

This study investigates the impact of banks' diversified income structure on profitability among Tunisian banks during 2010-2018. We examine banks’ profitability using accounting and market measures as relevant indicators. We focus on each category of non-interest income separately rather than on non-interest income as an overall measure to provide a clearer analysis helping bank managers assess relevant strategies, and show that income structure diversification enhances banks’ profitability, albeit with their mixed effects. The empirical analysis of panel data indicates that Tunisian bank’s market-to-book value is very sensitive to all types of non-interest income. Banking activity diversification improves stock market profitability particularly in large banks and a safe macroeconomic environment. However, only fees and commissions incomes increase Tunisian banks’ assets profitability. Positive fees and commissions incomes’ effect is more pronounced for large banks and in a deflationary environment. We conclude by recommending to Tunisian banks, the diversification of their activities and the search for non-interest income while trying to control the costs of adopting these innovations, to take the necessary precautions, and to develop their personal skills.
