This paper investigates the predictive impact of Financial Stress on hedging between the oil market and the GCC stock and bond markets from January 1, 2007, to December 31, 2020. The authors also compare the hedging performance of in-sample and out-of-sample analyses.

For the modeling purpose, the authors combine the GARCH-BEKK model with the machine learning approach to predict the transmission of shocks between the financial markets and the oil market. The authors also examine the hedging performance in order to obtain well-diversified portfolios under both Financial Stress cases, using a One-Dimensional Convolutional Neural Network (1D-CNN) model.

According to the results, the in-sample analysis shows that investors can use oil to hedge stock markets under positive Financial Stress. In addition, the authors prove that oil hedging is ineffective in reducing market risks for bond markets. The out-of-sample results demonstrate the ability of hedging effectiveness to minimize portfolio risk during the recent pandemic in both Financial Stress cases. Interestingly, hedgers will have a more efficient hedging performance in the stock and oil market in the case of positive (negative) Financial Stress. The findings seem to be confirmed by the Diebold-Mariano test, suggesting that including the negative (positive) Financial Stress in the hedging strategy displays better out-of-sample performance than the in-sample model.

This study improves the understanding of the whole sample and positive (negative) Financial Stress estimates and forecasts of hedge effectiveness for both the out-of-sample and in-sample estimates. A portfolio strategy based on transmission shock prediction provides diversification benefits.

This study aims to examine the impacts of board chairman characteristics on the decision to finance with debts.

Based on historical data from 173 active nonfinancial firms listed on Gulf Cooperation Council (GCC) Stock Exchange Markets during 2012–2019, this research uses ordinary least squares (OLS) and dynamic system-generalized methods of moments to test its hypotheses. The final dataset comprises 1,384 firm-year observations from 10 major nonfinancial industry classifications.

Results indicate a negative impact of board chairman ownership on the decision to finance with retained earnings (RE). Negative effects of the chairman and chief executive officer (CEO) from the same family on the decision to finance with RE, whereas positive effects of the chairman and CEO from the same family on the decision to finance with debts are observed. In addition, a negative effect of the chairman from a royal family on the decision to invest with debts is found.

Many board chairmen characteristics, such as age, gender, experience, education level, periodic change and ethnicity, are unaddressed. Financial decisions (FDs) are also limited to two decisions (internal financing with RE and external financing with debts).

Findings of this study provide an improved understanding of the role of chairman characteristics in FDs in GCC. Investors and lenders dealing with companies in GCC markets benefit from the authors' results because of the effects of chairman characteristics on FDs when making investment decisions in company stocks.

The study clarifies how each of the three board chairman characteristics (i.e. chairman ownership, chairman and CEO from the same family and the chairman from the royal family) affects FDs, especially the decisions to finance with debts and RE.

This study aims to investigate the asymmetric impact of daily announcements regarding COVID-19 on investor sentiment in the stock market.

This study uses a Non-Linear Autoregressive Distribution Lag (NARDL) model that relies on positive and negative partial sum decompositions of the Coronavirus indicators. Five investor sentiments had been used and the analysis is conducted on the full sample period from 24th February 2020 to 25th March 2021.

The results show that new cases have a greater impact on investor sentiment compared to daily announcements of new deaths related to COVID-19. In addition to revealing a significant impact of new COVID-19 new cases and new death announcements on a daily basis on investor sentiment over the short- and long-term, this paper also highlights the nonlinearity and asymmetry of this relationship in the short and long run. Investors' sentiments are more affected by negative news regarding Covid 19 than positive news.

Financial markets have been severely affected by COVID-19 pandemic. This study is the first to measure the extent of reaction of investors to positive and negative announcements of COVID-19. Interestingly, this study examines the asymmetric effect of daily announcements on new cases and new deaths by COVID-19 on investor sentiments and derive many implications for portfolio managers.

This study aims to examine how woman corporate leadership indicators and environmental, social and governance (ESG) disclosure in listed banks on Ghana Stock Exchange are related.

Data was obtained from the audited annual reports of the banks for the period 2006–2020. Empirical result estimation was achieved using Panel Corrected Standard Errors.

The result revealed that female chief executive officer (CEO), female board chairperson and board gender diversity are associated with higher disclosure of ESG issues in listed banks in Ghana in overall terms. However, in terms of individual disclosures, female board chairperson positively impacts social disclosure, whereas both female CEO and female board chairperson affect governance disclosure positively.

In this era of business where there is much emphasis on green business and investment by various stakeholders for purposes of ensuring business legitimacy, the result implies that banks must consider females to occupy the positions of CEO and board chairperson since that can help to improve ESG performance of banks.

In this era of business where there is much emphasis on green business, socially responsible investment and impact investment by various stakeholders, the result implies that banks must consider improving the representation of women in leadership since that can help to improve ESG performance of banks and hence ability to attract more investors.

To the best of the authors’ knowledge, this is the first study to provide empirical evidence from a developing country perspective in Sub-Saharan Africa that gender of bank leadership has implications for ESG disclosure.

This study aims to analyze the impact of digital transformation on firm performance within the banking sector, specifically focusing on the Amman Stock Exchange (ASE)-listed banks from 2015 to 2022. Additionally, it explores the influence of gender dynamics on the implementation and outcomes of these digital transformation initiatives.

The study adopts a robust empirical approach, using manual content analysis of annual reports from ASE-listed banks. The Digital Transformation Disclosure Index (DTDI) is used to assess the extent and nature of digital transformation initiatives within these banks. The methodology is designed to provide a comprehensive evaluation of the correlation between digital transformation efforts, firm performance and gender dynamics.

The research reveals that digital transformation initiatives have a significant positive impact on the performance of ASE-listed banks. It also uncovers nuanced insights into the role of gender dynamics, indicating that gender diversity within firms influences the adoption and success of digital transformation strategies in complex ways.

The findings of this study contribute to the understanding of digital transformation in the banking sector, offering empirical evidence on its benefits for firm performance. Additionally, the study illuminates the intricate role of gender dynamics in digital transformation, providing a new perspective on organizational diversity within the context of technological change.

This research pioneers in academically linking digital transformation and gender dynamics within the banking sector, addressing a notable gap and introducing a fresh academic perspective. Practically, it equips banking executives and policymakers with actionable insights for gender-inclusive digital strategies, crucial for enhanced firm performance. Methodologically, the study sets a benchmark in research innovation, using the DTDI to offer a replicable model for future investigations in this evolving field.

This paper aims to investigate the conditional equicorrelation and cross-quantile dependence between the DeFi, European and GCC currency markets (Oman, Qatar, Bahrain, Kuwait, Saudi Arabia and the United Arab Emirates).

This study applies the GARCH-DECO model and cross-quantilogram framework.

The findings reveal evidence of weak and negative average equicorrelations between the examined markets through time, excluding the COVID-19 outbreak and Russia–Ukraine conflict, which is consistent with the literature examining relationships in different markets. From the cross-quantilogram model, the authors note that the dependence between DeFi, EURO and GCC foreign exchange rate markets is greatest in the short run and diminishes over the medium- and long-term horizons, indicating rapid information processing between the markets under consideration, as most innovations are transmitted in the short term.

For the pairs of DeFi and currency markets, the static and dynamic optimal weights and hedging ratios are also estimated, providing new empirical data for portfolio managers and investors.

To the best of the authors’ knowledge, this is one of the most important research looking into the conditional correlation and predictability between the DeFi, EURO and GCC foreign exchange markets. More importantly, this study provides the first empirical proof of the safe-haven, hedging and diversification qualities of DeFi, EURO and GCC currencies, and this work also covers the COVID-19 pandemic and the Russia–Ukraine war with the use of a single dynamic measure produced by the GARCH-DECO model. In addition, the directional predictability between variables under consideration using the cross-quantilogram model is examined, which can be capable of capturing the asymmetry in the quantile dependent structure. The findings are helpful for both policymakers and investors in improving their trading selections and strategies for risk management in different market conditions.

The findings reveal Islamic finance’s potential to significantly contribute to the GCC’s economic diversification and resilience against global economic downturns. The study highlights how Islamic finance aligns with the sustainable development goals and its effectiveness in promoting ethical financial practices and socio-economic justice.

Future research should focus on global comparative studies to understand Islamic finance’s impact on sustainable development beyond the GCC. Longitudinal studies are also essential to assess the long-term effects of Islamic financial instruments on economic stability.

The research advocates for incorporating Islamic finance principles into the GCC’s economic strategies, emphasising its role in providing resilient and ethical financial alternatives conducive to sustainable development. It underscores the need for policy initiatives integrating Islamic finance to bolster socio-economic welfare and environmental sustainability.

Offering a novel perspective, this paper enriches the discourse on the contribution of Islamic finance to sustainable economic development. It presents critical insights into how Islamic finance can underpin long-term economic resilience and growth in the GCC. It provides valuable implications for academia and policymaking, particularly in emerging economies’ science and technology policy management.

Management research has emphasized the effects of slack resources on the decision-makers’ strategic choices. Behavioral theorists have argued for a positive effect of slack through encouraging search and innovation while agency theorists have emphasized that slack can accentuate the principal–agent problem, which negatively affects firm performance. This paper aims to extend this argument and empirically investigate the separate effects of three types of slack resources (i.e. available, recoverable and potential) on firm performance in an important emerging market, namely, the Gulf Cooperation Council (GCC).

The two-step system generalized method of moments (Sys-GMM) is applied to a panel of 360 firms in the six GCC countries, namely, Kuwait, Saudi Arabia, UAE, Qatar, Oman and Bahrain, over the period between 1999 and 2019.

The authors find that available and potential slack are both negatively associated with firm performance. The relationship between recoverable slack and performance is quadratic (inverse U-shaped) where recoverable slack improves performance only up to a specific point, but after that level, recoverable slack starts to negatively affect the performance of the firm.

This paper contributes to the literature in three important ways. First, this paper advances a first attempt to differentiate between three separate types of slack on firm performance in the context of the GCC market. Second, this paper empirically investigates the presence of the principal–agent problem in the GCC market and relates it to the ongoing debate on the agency effects of slack resources. Finally, this paper underlines the effects of institutional frameworks and environments on the relationship between slack resources and firm performance.
