This research investigated whether corporate social responsibility (CSR) can alleviate the negative effect of non-performing loans (NPLs) on bank performance.

The research employed a sample of European banks over the 2008–2017 period. To resolve endogeneity and heterogeneity problems, the system generalized method of moments (SGMM) model was employed.

First, bank NPLs were negatively and significantly associated with bank performance as measured by the Q-Tobin ratio and the return on assets (ROA). Second, CSR scores exerted a negative and significant effect on the level of NPLs. Finally, the results indicated that bank performance could benefit from the interactional effect of CSR and NPLs.

This study fills the gap in the debate over the mediating role of CSR in the NPLs – bank performance interrelation. In addition, our SGMM analysis yielded more robust and efficient results while resolving endogeneity and heterogeneity problems concerning CSR and bank performance or risk in corporate finance.

CSR practices can play an essential mediating role in the NPLs–bank performance relationship. CSR activities in the European context may reduce the level of NPLs and increase bank performance.

To the best of the authors’ knowledge, studies of the implications of CSR activities on the banking sector are very limited. Indeed, this paper shows that CSR mediates the relationship between CSR practices and NPLs. The results suggest that bank performance could benefit from the interactional effect of CSR and NPLs.

The purpose of this paper is to analyze the effects of corruption on investment and growth in 15 Middle East and North African (MENA) countries during the period 1985-2013. The authors used the International Country Risk Guide (ICRG) corruption index and conducted a panel cointegration analysis and Granger causality procedure to detect the dynamic relationships between the variables. Results indicate that corruption is a serious hurdle to economic growth in MENA countries since it affects investment activities and foreign direct investment inflows. In this case, policymakers have to implement effective anti-corruption strategies to avoid the epidemic of corruption.

The main findings of this paper show that corruption is a serious hurdle to economic growth in MENA countries since it affects investment activities and foreign direct investment inflows. In this case, policymakers have to implement effective anti-corruption strategies to avoid the epidemic of corruption.

Unfortunately, in this study the authors did not use institutional variables to see their role and to judge whether governments should enhance the quality of institution and improve the corporate governance. This would be an opportunity to expand the sample and to conduct a new research in the near future to assess the real costs of corruption in the MENA region.

Governments and policymakers need to apprehend and admit that corruption is an important issue that deters foreign direct investment and threats the economic development and growth. Corruption can also deteriorate the infrastructure and increase the cost of doing business for both government and private sector which in turn will lower the growth (Tanzi and Doovi, 1997). It is worth recalling that during the past five years, a large part of the MENA region has witnessed multiple social upheavals. Hence, corruption must be tackled effectively and coherently to avoid further social tensions. It is the proper time to take serious steps and strict policy actions within a zero-tolerance framework to fight corruption and its widespread. New rules, laws, and anti-corruption procedures are among the most important initiatives that governments should implement. The governments should also increase the public awareness of the multiple drawbacks of corruption by publishing official reports and data on the most corrupted sector in the country. In this case, media will have a key role to diffuse the necessary information.

While most of the previous studies have employed GMM and OLS techniques, the authors opt a panel vector error correction model and cointegration technique to detect causality between the variables used in the model for the present study.

Although most previous studies interested in Islamic banks have focused on quantitative aspects such as performance, risk and stability, this paper aims to deal with the institutional dimension and focus precisely on the link between board characteristics and bank performance.

Based on a data related to 13 banks in Bahrain observed over the period of 2005-2011, this study investigates the impact of board directors on the level of performance. To this end, the authors have used two empirical approaches. The first one is the panel data analysis with regard to random effect (RE) regression. The second one is the generalized method of moments (GMM) in system, which checked the soundness of the first result.

The result of RE regression indicates that the board duality is positively and significantly correlated with the bank performance for both ROA (return on assets) and ROE (return on equity). However, the board size exerts a positive and significant impact only when profitability is measured by ROE. The authors find that regression with GMM in system confirms the RE result exclusively for ROE. Findings also indicate that a financial crisis exerts a negative but not significant effect on bank performance.

These findings are relevant to both policymakers and regulators. Islamic banks in Bahrain should grant more importance to the structure and the quality of the board to improve their performance.

This study aims to extend the existing literature by focusing about the role of the Shariah board in bank performance.

The authors examine the effect of greenhouse gas (ghg) assurance on cost of debt, and the effect of board gender diversity on cost of debt, for an international sample of listed companies.

Utilizing firm-level data and a quantile regression approach, this study examines the effects of greenhouse gas assurance and board diversity on cost of debt by employing an international sample of firms during 2015–2021.

The authors find that in firms with a relatively low cost of debt the external assurance of greenhouse gas emissions and gender diversity could significantly contribute to a reduction of cost of debt. Furthermore, other measures of board diversity that are linked with independent directors and skilled directors seem to contribute to an increase of firms' cost of debt in the lower end of distribution. Drawing from the agency theory, the authors showcase the fact that ghg assurance reduces information asymmetry and therefore agency costs such as borrowing costs and signals to the stakeholders a long-term commitment to excellence.

This study is the first that provides insights on the relationship between ghg assurance, board diversity and cost of debt.

This paper aims to investigate the reciprocal nonlinear relationship between corporate social responsibility (CSR) and firm performance (FP).

The authors used a sample of 814 European firms over the period 2008–2017. The Panel Smooth Transition Regression (PSTR) model was performed as an econometric approach.

Firstly, results show a threshold effect in the CSR–FP relationships within the two directions. More specifically, the authors found that firms are more likely to engage in CSR by surpassing a threshold of 1.231% for return on assets (ROA) and 0.821% for Tobin’s Q ratio. Secondly, the authors also found that the impact of CSR on FP is positive and significant only if the environment, social and governance score surpasses the threshold of 56.780% when the dependent variable is ROA and 41.02% when Tobin’s Q ratio measures performance.

A significant part of the literature supports the linear relationship between CSR and FP from the unique direction (CSR → FP). This study comes to fill this gap by assessing the possible nonlinear relationship. In addition, this nonlinear relationship is tested under the two directions. Therefore, defining the threshold of FP that allows companies to engage in CSR, on the one hand, and the threshold of engagement in CSR that improves FP, on the other hand, could be an exciting topic.

To get the full benefit from CSR effects, firms should be with better financial performance to be socially responsible.

To the best of our knowledge, few studies have explored the nonlinear relationship between CSR and FP. In addition, this study raises the question of whether this relation is causal. The authors assess the two nonlinear relationships between CSR ? FP and FP ? CSR by determining the optimal thresholds.

本文旨在探究企業社會責任 (以下簡稱企社責) 與公司業績之間的相互非線 性關係。

研究所採用的樣本為814間歐洲公司, 涵蓋期為2008年至2017年。研究人 員使用縱橫平滑轉換模型、作為經濟計量方法和工具去進行研究。

研究結果顯示、在有關的兩個方向內, 企社責與公司業績之間的關聯上是 存在著閾值效應的。更具體地說, 研究人員發現, 若企業的資產報酬率超過1.231%的 水平, 以及托賓的Q比率 (Tobin’s Q Ratio) 0.821%的水平的話, 它們會更願意承擔企 社責。其次, 研究結果亦顯示, 企社責對企業的業績會產生積極的影響; 另外, 只有 當資產報酬率是因變數、而環境、社會和公司治理的分數 (ESGS) 超過56.780%, 以 及當托賓的Q比率用來測量績效、而數值為41.02%時, 企社責對企業的業績所產生的 影響會較為顯著。

過去的學術文獻、大部份都是以唯一的方向 (企社責 ->公司業績) 去確認 企社責與企業業績之間的線性關係。本研究評估了兩者之間可能存在的非線性關係; 而且, 這非線性關係是在有關的兩個方向下而進行測試的; 因此, 本研究一方面給可 讓公司以企社責的精神和理念去營運的企業業績的閾值下了定義; 另一方面, 又給參 與企社責為公司帶來業績的改善的閾值下了定義。這均為令人興奮的課題。

企業若想取得因參與企社責而帶來的完全好處, 它們必須擁有更佳 的財務績效、以能盡其社會責任。

盡我們所知, 探究企社責與企業業績之間的非線性關係的研究實在不 多; 而且, 本研究對這兩者的關係是否是因果關係提出了質疑; 就此, 我們藉著釐定 最佳的相對閾值、來評估企社責 ->企業業績與企業業績 ->企社責之間的兩個非線性的 關係。

This paper aims to focus on the main determinants of the performance and stability-banking sector in the Middle East and North Africa (MENA) region during the global financial crisis. Using a data set of 13 countries with both of 77 Islamic and 101 conventional banks during the period 2006-2013, empirical results show that specific variables allow explaining the change in the level of performance and stability for conventional and Islamic banks. However, the effect of some banks’ characteristics is not the same for the two bank groups. For the macroeconomic effect, it is observed that inflation exerts a negative effect on the bank performance except for conventional banks when it increases the profitability.

Using a data set of 13 countries with both of 77 Islamic and 101 conventional banks (CvB) during the period 2006-2013 and performing the generalized method of moments (GMM) method, the findings provide comprehensive evidence for the bank systems studied which are of interest also to policy makers and practitioners.

The main finding is that after the international financial crises of 2008, many worldwide banks have been experiencing crises in contrast to Islamic banks (IsB) which remain Gen more stable and more profitable. Foreign banks had a higher degree of exposure to risk, given their higher number of subsidiaries in the developed economies. As for the determinants of profitability, the bank-specific variables allow to explain the change in the level of performance and stability for conventional and Islamic banks. However, the effect of some banks characteristics is not the same for the two bank groups. For the macroeconomic effect, it is observed that inflation exerts a negative effect on the bank performance except for CvB when it increases the profitability measured by the return on assets (ROA). It is also found that the growth rate acts positively when the dependent variable is the ROA and negatively when the performance is measured by return on equity.

The inflation rate exerts a negative effect only on the ROA. This study differs from previous contributions in that it is tested the hypothesis of determinants of bank profitability and stability for both conventional and Islamic banks in the MENA region. It is of great interest to both policymakers and investors, with respect to regional development policies and dedicated portfolio investment strategies in each emerging region respectively. The authors adopted several ratios from the empirical literature on bank profitability and stability. Using a data set of 13 countries with both of 77 Islamic and 101 CvB during the period 2006-2013 and performing the GMM method, the findings have significant contributions to the literature by comprehensively clarifying and critically analyzing the current state of profitability and stability for both banks.

The aim of this paper is to examine whether multiple large shareholders and their interactions affect bank profitability in the MENA region.

To achieve this goal, we used a sample of conventional banks in the MENA region observed during the period 2004–2015. We performed the System Generalized Method of Moment as the empirical approach.

Empirical results indicate that under the dispersion hypothesis, multiple large shareholders (MLS) tend to reduce bank profitability for both return on assets (ROA) and return on equity (ROE). However, under the alignment of interests’ hypothesis, coalition between the first and the second largest shareholder increases bank profitability only for ROA. We also find that an additional large shareholder, beyond the two largest, reduces bank return equity.

To the best of our knowledge, to date, there is no study that investigates the effect of MLS and the bank profitability in the MENA region. Indeed, this study shows the importance of considering ownership composition among large shareholders in banking studies.

The credit crunch of 2008 and recent COVID-19 influences underscored the importance of liquidity and credit risk management in businesses and financial institutions. The purpose of this study is to investigate the impact of liquidity risk and credit risk management on accounting and market performances of banks operating in the Middle East and North Africa (MENA) region.

This study uses a panel data regression analysis on a sample of 51 listed commercial banks operating in 10 MENA countries during the period 2010–2018.

The results show that credit risk management does not affect the accounting performance of banks, while it has a non-linear, convex relationship with market performance. Surprisingly, liquidity risk management is not a significant driver for either performance measure in studied banks. However, when a bank combines credit risk management with liquidity risk management efforts, liquidity risk management actions return significant results on both performances, illustrated by an inverted U-shaped relationship. In addition, this study examines the joint impact of both risks on bank performance. This study reveals that accounting and market performances are differently affected by joint risk management efforts. Their impact depends on the combination of risk management ratios upon which banks choose to focus their efforts.

The findings help bankers and regulators further consider non-linearities and offer them new tools for managing the impact of credit and liquidity risk interactions towards achieving more financial stability.

These results contribute to traditional banking in offering bankers and regulators new tools for managing the impact of credit and liquidity risk interactions on bank performance.

The purpose of this research is to examine the connections between liquidity risk, credit risk, and bank profitability in India.

In order to examine the interlinkage between liquidity risk, credit risk, and profitability of banks in India, the researcher has gathered data from all commercial banks in India from 2004–2005 to 2020–2021. The data sources included in this study encompass the International Country Risk Guide, World Development Indicators and Reserve Bank of India (RBI). Seemingly Unrelated Regression (SUR) has been utilised for the study.

Findings of this research identified that liquidity risk is inversely proportional to credit risk. Return on assets (ROA) and return on equity (ROE) are both impacted negatively by liquidity risk. ROA is impacted positively by credit risk, while ROE is impacted negatively by it. The profitability of banks is harmed by the interaction between liquidity risk and credit risk. It also shows that law and order, are beneficial to bank earnings and risk management. The capital risk-adjusted ratio has a negative relationship with bank profitability, indicating the need for better capital allocation.

The originality of this work lies in its unique contributions, It emphasises explicitly the Indian context, thereby providing insights tailored to this particular setting. It employs the SUR methodology, a statistical approach allowing for a more comprehensive data analysis. Additionally, it identifies and explores interaction effects, which can shed light on the complex relationships between variables.

This paper aims to present the capacitance characterization of tapered dielectrophoresis (DEP) microelectrodes as micro-electro-mechanical system sensor and actuator device. The application of DEP-on-a-chip (DOC) can be used to evaluate and correlate the capacitive sensing measurement at an actual position and end station of liquid suspended targeted particles by DEP force actuator manipulation.

The capability of both, sensing and manipulation was analysed based on capacitance changes corresponding to the particle positioning and stationing of the targeted particles at regions of interest. The mechanisms of DEP sensor and actuator, designed in DOC applications were energized by electric field of tapered DEP microelectrodes. The actual DEP forces behaviour has been also studied via quantitative analysis of capacitance measurement value and its correlation with qualitative analysis of positioning and stationing of targeted particles.

The significance of the present work is the ability of using tapered DEP microelectrodes in a closed mode system to simultaneously sense and vary the magnitude of manipulation.

The integration of DOC platform for contactless electrical-driven with selective detection and rapid manipulation can provide better efficiency in in situ selective biosensors or bio-detection and rapid bio-manipulation for DOC diagnostic and prognostic devices.
