Do board characteristics affect bank performance? Evidence from the Bahrain Islamic banks

Purpose 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. Design/methodology/approach 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. Findings 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. Practical implications 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. Originality/value This study aims to extend the existing literature by focusing about the role of the Shariah board in bank performance.

Patents vs publications and R&D : three sides of the same coin? Panel smooth transition regression (PSTR) for OECD and BRICS countries

ABSTRACT The paper aims to define the optimal thresholds of publications and Research and Development (R&D) expenditure and to investigate their impacts on patenting in OECD and BRICS countries. To do so, we use a dataset of 25 countries divided into two country sub-samples for the period 1996–2013, employing the Panel Smooth Transition Regression (PSTR) model. The results indicate that the threshold of publications after which patenting activity is promoted is 8417 publications for the OECD countries and 20,848 for the BRICS countries, while the share of R&D in % of GDP should not exceed 1.683% for the OECD countries and 0.975% for the BRICS countries.

Banking stability in the MENA region during the global financial crisis and the European sovereign debt debacle

Purpose 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. Design/methodology/approach 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. Findings 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. Originality/value 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.
