Bank governance,regulation, supervision,and risk reporting: Evidence from operational risk disclosures in European banks

This paper investigates the direct and joint effects of bank governance, regulation, and supervision on the quality of risk reporting in the banking industry, as proxied for by operational risk disclosure (ORD) quality in European banks. After controlling for the endogeneity between bank stability and risk reporting quality, we find that banks having a higher proportion of outside board directors, lower executive ownership, concentrated outside non-governmental ownership, and more active audit committee, and operating under regulations promoting bank competition (i.e., less stringent entry to banking requirements) provide ORD of higher quality. In addition, we find that the contribution of bank supervisors to the enhancement of ORD quality depends on the ownership structure of the bank. Specifically, powerful and independent bank supervisors mitigate the incentives for entrenched bank executives to withhold voluntary ORD. Moreover, bank supervisors and largest shareholders perform substitutive roles in monitoring the bank management's compliance with mandatory ORD requirements. For the sake of enhancing risk reporting quality in banks, our findings recommend sustaining board independence, enhancing audit committee activity, easing entry to banking requirements, and promoting a more proactive role for bank supervisors.     

Shariah governance in Islamic banks: Practices,practitioners and praxis

This study examines Shariah governance in Islamic banks by analyzing and comparing international and national Shariah governance codes across 11 countries and the annual reports of the largest stand-alone Islamic bank in each of these countries. Drawing upon the practice theory framework, this study identifies the similarities and differences across countries in Shariah governance practices, practitioners, and praxis. Regarding practices, we found that the 11 countries reviewed have adopted different approaches, i.e., strict, moderate, or flexible approaches, in developing regulations for Shariah governance structures and processes. The approach taken by each country, in turn, influences Shariah governance practitioners and praxis at the institutional level to some extent. Specifically, Islamic banks in countries belonging to the moderate and flexible groups are likely to be more varied in terms of Shariah governance practitioners as well as praxis (activities or processes) to ensure Shariah compliance as compared to their counterparts in countries with strict regulations. Analyzing current Shariah governance practices in these 11 countries can promote a greater understanding and resolution in addressing critical issues due to different contextual circumstances. Therefore, the findings of this study can provide relevant information for both regulators and practitioners to further improve the Shariah governance best practices in the Islamic banking industry.     

The governance,risk-taking,and performance of Islamic banks

We examine whether the difference in governance structures influences the risk taking and performance of Islamic banks compared to conventional banks. Using a sample of 52 Islamic banks and 104 conventional banks in 14 countries for the period from 2005 to 2013, we conclude that the governance structure in Islamic banks plays a crucial role in risk taking as well as financial performance that is distinct from conventional banks. Particularly, we show that the governance structure in Islamic banks allows them to take higher risks and achieve better performance because of product complexities and transaction mechanisms. However, Islamic banks maintain a higher capitalization compared to conventional banks. These results support the research on Islamic investment and risk taking. Our results add a new dimension to the governance research that could be a valuable source of knowledge for policy makers and regulators in the financial services sector.     

The impact of state and foreign ownership on banking risk: Evidence from the MENA countries

This paper investigates the impact of foreign and state ownership on banking risk. Panel data regression analysis is applied to a sample of 171 commercial banks from the MENA region during the 2006–2012 period. Two-stage least-squares analysis is conducted. Our results show that State ownership encourages banks to take more risks while foreign ownership reduces risk-taking. In addition, state-owned banks tend to increase capital adequacy ratio to hedge against high level of risk. Our finding also indicates that all categories of shareholders take a prudent attitude that influences risk reduction after the 2008 crisis.     

Differences and similaritites between corporate governance principles in Islamic banks and Conventional banks

The purpose of this paper is to present the some differences and similarities between corporate governance principles in Islamic banks and conventional banks by paradigmatic diversification. Since Corporate governance in Islamic banks is a social phenomenon in Islamic societies, the paper uses social theory paradigms (functionalist, interpretive, radical humanist and radical structuralist) to compare between corporate governance in Islamic banks and conventional banks. This paper demonstrates that mainstream corporate corporate governance theories are not a law of nature but a social construct.     

Hyperbolic distance function,technical efficiency and stability to shocks: A comparison between Islamic banks and conventional banks in MENA region

In this paper, we compare banking performance and resiliency between Islamic banks and conventional banks in MENA region over the period 2002–2014. Stochastic hyperbolic and radial output distance functions are employed to evaluate banking performances. Furthermore, hyperbolic distance function methodology is extended to evaluate bank's business risk through simulations. Historical extreme observed situations in terms of profit loss from the industry are used in order to simulate their impact on the overall profit distribution within the industry. More precisely, we compare the observed profit and the simulated one followed by an abrupt fall in bank lending and non-lending activities. Results find evidence of technical efficiency differences with bank type, some evidence with bank size. It is found that conventional banks are much more vulnerable to an important drop on their lending activities than non-lending activities, while Islamic banks are equally vulnerable to any drop of the activity. Furthermore, Islamic banks are found to be less vulnerable than their counterparts when they are exposed to shocks on their lending activities. Very large banks are much more resilient than small banks whatever is the bank stream. It is also found that bank vulnerability is more important when the banks are not able to adjust their costs in the short run, and increases with the exposure to higher shocks in magnitude.     

Cost efficiency of banks in transition: Evidence from 289 banks in 15 post-communist countries

To understand the transformation of banking in the post-communist transition, we examine the cost efficiency of 289 banks in 15 East European countries. We find that banking systems in which foreign-owned banks have a larger share of total assets have lower costs and that the association between a country’s progress in banking reform and cost efficiency is non-linear. Early stages of reform are associated with cost reductions, while costs tend to rise at more advanced stages. Private banks are more efficient than state-owned banks, but there are differences among private banks. Privatised banks with majority foreign ownership are the most efficient and those with domestic ownership are the least.

Shari’ah supervision,corporate governance and performance: Conventional vs. Islamic banks

The performance and accountability of boards of directors and effectiveness of governance mechanisms continue to be a matter of concern. Focusing on differences between conventional banks and Islamic banks, we examine the effect of (i) Shari’ah supervision boards, (ii) board structure and (iii) CEO-power on performance during the period 2005–2011. We find Shari’ah supervision boards positively impact on Islamic banks’ performance when they perform a supervisory role, but the impact is negligible when they have only an advisory role. The effect of board structure (board size and board independence) and CEO power (CEO-chair duality and internally recruited CEO) on the performance of Islamic banks is overall negative. Our findings provide support for the positive contribution of Shari’ah supervision boards but also emphasize the need for enforcement and regulatory mechanism for them to be more effective.     

Competition,concentration and risk taking in Banking sector of MENA countries

This paper tests the relationship between competition and bank stability for 356 banks operating in the Middle East North Africa (MENA) countries during the period 2005–2012. Our results show that for the overall sample, a U-shaped relationship between competition and banks’ risk taking for MENA banks. The negative linear relationship between Z-Score and H-statistics in Gulf countries shows that an increase in competition leads to a reduction in the level of financial stability. In the case of other non-Gulf countries, the increase of competition in uncompetitive markets can lead to an increase in stability. The results confirm the importance of the market structure as an explanatory factor for financial stability, but also indicate that concentration is not associated with uncompetitive markets.     

Financial derivatives,opacity, and crash risk: Evidence from large US banks

We test how the use of financial derivatives affects banks’ informational structure and future stock performance based on a sample of large bank holding companies in the US. Using banks’ use of financial derivatives as a proxy for opacity, we find that high level use of interest rate and foreign exchange derivatives are associated with an increase in the synchronicity (R²) of stock price movements with the market index, which indicates less revelation of bank-specific information to the market. This finding is consistent with the prediction of the model developed by Wagner (2007). We document that superior corporate governance tempers these effects. Finally, we find that an increase in the opacity is significantly and positively related to an increase in banks’ future stock price crash risk.     

Stock markets, banks, and economic growth: Empirical evidence from the MENA region

Over the last four decades, a wide theoretical debate is concerned with the fundamental relationship between financial development and economic growth. Recent studies shed some light on the simultaneous effect of banks and financial system development on growth rather than a separate impact. The empirical study is conducted using an unbalanced panel data from 11 MENA region countries. Econometric issues will be based on estimation of a dynamic panel model with GMM estimators. Thus, peculiarities of MENA region countries will be detected. The empirical results reinforce the idea of no significant relationship between banking and stock market development, and growth. The association between bank development and economic growth is even negative after controlling for stock market development. This lack of relationship must be linked to underdeveloped financial systems in the MENA region that hamper economic growth. Then, more needs to be done to reinforce the institutional environment and improve the functioning of the banking sector in the MENA region. Based on these results, other regions at the same stage of financial development such as Africa, Eastern Europe or Latin America should improve the functioning of their financial system in order to prevent their economies from the negative impact of a shaky financial market.     

Risk shifting and regulatory arbitrage: Evidence from operational risk

We document a robust negative relation between operational risk exposure and bank capital levels for a sample of large U.S. banks under the Basel I Capital Accords. The results are consistent with the notion that capital-constrained banks increased operational risk exposure at the time when Basel I regulations did not require an explicit capital charge for operational risk. More broadly, our results show new channel by which financial regulations incentivize banks to shift their risk taking to less regulated risk areas. We focus on the case of operational risk because it went from a largely unregulated risk type to a major risk that accounts for about 25% of large U.S. banks’ risk-weighted assets.     

Greenwashing in environmental,social and governance disclosures

The environmental, social, and governance (ESG) data provided in firms’ sustainability reports is often unaudited. If ESG information disclosed by firms is not reliable, a firm’s greenwashing behavior can be a barrier to integrating ESG factors into investment decisions. In this paper, we study mechanisms to lessen firms’ greenwashing behavior in ESG dimensions holistically. Firstly, we identify “greenwashers” as firms which seem very transparent and reveal large quantities of ESG data but perform poorly in ESG aspects. By creating peer-relative greenwashing scores for a cross-country dataset comprised by 1925 large-cap firms, we measure the extent to which large-cap firms engage in greenwashing. We find evidence that greenwashing behavior in ESG dimensions can be deterred by scrutiny from (a) independent directors, (b) institutional investors, (c) influential public interests via a less corrupted country system, and (d) being cross-listed. Our results suggest that the two firm-level governance factors are most effective at attenuating firms’ misleading disclosure relating to ESG dimensions.     

Using partial least square discriminant analysis to distinguish between Islamic and conventional banks in the MENA region

The deterioration of bank profitability poses a threat not only to the interests of consumers and internal staff members but also affects investors who may equally suffer from significant financial losses. It is important to establish an effective system which assists investors in their investment choices. In prior literature, traditional models have been developed, but achieved short‐term performances such as logistic regression and discriminant analysis. This paper applies a partial least squares discriminant analysis (PLS‐DA) to distinguish between conventional and Islamic banks in the Middle East and North Africa (MENA) region based on the financial information for the period 2005–2011. This method can successfully identify the non‐linearity and correlations between financial indicators. The results demonstrate superior performance of the proposed method. On one hand, our model can select all financial ratios to distinguish between banks and at the same time identify the most important variables in the distinction process. On the other hand, the proposed model has high levels in terms of accuracy and stability.     

Board structure and the informativeness of risk disclosure: Evidence from MENA emerging markets

We examine whether board characteristics affect firms' decision to voluntarily disclose informative information about their risk profiles. We base our study on data from 320 listed firms in nine MENA emerging markets (789 observations) over the period from 2007 to 2009. Our study offers significant contributions to the growing risk disclosure literature. It provides new empirical evidence that information driven by some board characteristics affects the perceived relevance of narrative risk information. Our findings suggest that the composition of the board and its size enhance the informativeness of risk disclosure as it allows investors to better predict future earnings growth. A further finding is that a CEO/Chairperson duality does not impact the way investors trust risk disclosures.     

The role of banks in the governance of nonfinancial firms: Evidence from Europe

The aim of our research is to investigate the important role of banks in the governance of companies listed in the Euronext 100 index. Primarily, this research seeks to examine the impact of a bank’s presence within a firm, as a creditor or shareholder, on firm performance, as well as the motivations of banks to acquire holdings, and whether the presence of a bank as a shareholder of a firm facilitates its access to bank loans. Empirical analyses are conducted with a sample of 86 nonfinancial institutions listed in the Euronext 100 index over the period 2008–2013 using the three-stage least squares method. The study shows, first, that the presence of a bank within a firm, as a creditor or shareholder, is positively related to firm performance. Moreover, the firm’s performance is an important determinant of the presence of bank shareholding. Finally, the presence of a bank as a shareholder of a firm does not facilitate its access to bank loans.     

Testing the inflation rates in MENA countries: Evidence from quantile regression approach and seasonal unit root test

We investigate the dynamic behavior and seasonal property (with regime shift) of inflation in the Middle East and North Africa (MENA) countries. Our investigation uses the quantile regression approach developed by Koenker and Xiao (2004) and the newly developed seasonal unit root test of Narayan and Popp (2011) respectively. Our empirical results show that the inflation rates are not mean-reverting, and they show the asymmetries in their dynamic adjustment. Further, we find a seasonal unit root does not exist in the inflation rate for any country in this study. This finding implies that shocks do not have lasting effects on the inflation rate.     

The association between employee stock option disclosures and corporate governance: Evidence from an enhanced disclosure regime

This study examines the role of corporate governance in employee stock option (ESO) disclosures following the revision of AASB 1028 Employee Benefits in 2001. We find that, while firms do not fully comply with AASB 1028 ESO disclosures, they voluntarily provide other ESO disclosures. In relation to corporate governance measures that have a role in the financial reporting process, we find two corporate governance measures dominate our results—the quality of auditor and duality of the role of CEO and Chair of the Board of Directors. We show that, in general, external auditor quality has positive incremental association with both mandatory and voluntary ESO disclosures while the dual role of CEO and chairperson of the board is associated with lower levels of mandatory disclosure.
