Convergence of Bank Efficiency in Emerging Markets: The Experience of Central and Eastern European Countries

In this study, we investigate the effect of the European Union integration process on banks' efficiency and the convergence of cost efficiency across banking systems from Central and Eastern European countries for the period 2004-10. We observe large differences in the levels of cost efficiency among national banking systems, and we notice an increase in banking efficiency for all banking systems until 2008. However, starting with 2009, the evolution of the average scores of cost efficiency declines. The results provide evidence of β-convergence and σ-convergence in terms of cost efficiency among the banking systems, especially during the period 2009-10.     

Multilayer information spillover networks between oil shocks and banking sectors: Evidence from oil-rich countries

There is no doubt that oil price shocks significantly affect oil-producing countries' macroeconomic fundamentals and financial stability, mainly in crisis times. The recent oil price shocks, coupled with the COVID-19 pandemic, motivated us to investigate the connectedness and risk transmission among oil shocks and banking sectors in the Gulf Cooperation Council (GCC) economies from June 30, 2006, to September 9, 2021. Thus, we construct multilayer information spillover networks between oil price shocks and GCC banking sectors. The empirical results show that the Bahrain banking sector depicts the highest connectedness and risk transmission with oil price shocks on the extreme risk spillover layer. In addition, Kuwait and the United Arab Emirates are highly connected to oil demand shocks. Furthermore, we find a substantial increase in extreme risk spillover and volatility spillover layers during the COVID-19 period. The results of this paper have some important implications for regional portfolio risk management, alleviating systemic risk, and developing hedging and investment strategies.     

Convergence in banking efficiency across European countries

Our paper aims to check whether financial integration has taken place on the EU banking markets, by investigating the convergence in banking efficiency for European countries between 1994 and 2005. We provide evidence of cross-country differences in cost efficiency and of an improvement in cost efficiency for all EU countries. β and σ convergence tests for panel data show a process in convergence in cost efficiency between EU countries. Robustness checks with alternative specifications confirm these findings. These results support the view that financial integration has taken place on the EU banking markets in the recent years.     

Nonperforming loans in the GCC banking sectors: Does the Islamic finance matter?

This paper investigates the bank-level and country-level factors determining nonperforming loans (NPL) in the commercial banking industry of Gulf Cooperation Council (GCC) countries. Specifically; it examines the impact of the sectoral distribution financing growth and Islamic finance methods growth on NPL. To do so, we apply generalized method of moments (GMM) techniques, over the 2005–2011 period. Our findings indicate that the sectoral distribution of Islamic financing has an adverse impact on NPL, which suggest that the sectoral financing growth of Islamic banks increases the credit risk exposure more than conventional banks. The findings of the Islamic finance methods growth show that the impact of fixed-income debt contracts could increase NPL more than profit-and-loss-sharing contracts.     

The influence of oil prices on the banking sector in oil-exporting economies: Is there a psychological barrier?

This paper examines the relationship between crude oil prices and banking sector market indices in the oil-exporting economies of the Gulf Cooperation Council (GCC), using daily frequency data over 2010–2017. Controlling for global banking impacts (S&P500 Banking Index) and interest rates (T-bills), dynamic ordinary least squared (DOLS) and fully modified ordinary least squared (FM-OLS) analysis indicates that oil prices positively affect bank indices until the $95 per barrel mark, after which the impact becomes negative, close to the psychological barrier found in the US equity market. The S&P500 Banking Index positively affects the GCC banking sector, whereas the interest rate affects it negatively. The validity of an inverse U-shaped relationship between crude oil price and banking sector indices is demonstrated. Causality analysis reveals the existence of bidirectional causalities between the prices of crude oil, GCC banking sectors, and the US banking sector. This paper demonstrates a vital non-linear relationship for oil-banking portfolio management and hedging strategies with oil price risk.     

Effect of Shariah Compliance on Operating Performance: Evidence from GCC Countries

We examine the operating performance of Shariah-compliant (SC) vs. non-Shariah-compliant (NSC) firms in six Gulf Cooperation Council (GCC) countries during 2000–2014 using a unique dataset from S&P’s Compustat Global database and show robust evidence that SC firms are operationally much more profitable than NSC firms. We show that higher operating profit margin (due to lower cost structure) and higher total asset turnover (i.e., asset efficiency) of SC firms compared to NSC firms are the primary drivers of the profitability difference. We also find that this association is more pronounced for firms that are always SC or always NSC during sample period.     

Bank performance and convergence during the financial crisis: Evidence from the ‘old’ European Union and Eurozone

This paper investigates the process of banking integration in the EU15 countries and the Eurozone by testing for convergence in bank efficiency among commercial banks. We use a two-step approach: First we estimate efficiency by applying an innovative methodological approach that treats banks’ non-performing loans as an undesirable output. Second, we apply the Phillips and Sul (2007) panel convergence methodology to assess the convergence process in European banking. Our results indicate an overall decline in efficiency and no evidence of group convergence following the financial crisis. However, we find the presence of club formation with typically weak convergence. The heterogeneity displayed by the transition parameters for the individual countries and the notable decrease in competition levels post 2008 highlight the impact of the financial crisis on the integration process.     

The transmission of market shocks and bilateral linkages: Evidence from emerging economies

The linkage between emerging and developed economies spans beyond the usual trade in goods and services. Underlying trade is the flow of capital for foreign direct investment and for speculation in markets, which renders emerging economies vulnerable to shocks from the developed world. As such, equity return volatility in emerging markets is partly attributable to this dependence. To gauge the importance of bilateral economic and cultural factors in driving economic integration, we adopt a two-step process. First, we use Diebold and Yilmaz's spillover index methodology to extract spillover indices representative of the return volatility spillover effects of the United States, the developed portion of the Euro area, and Japan on financial markets in Asia, the Gulf Cooperation Council countries, Eastern and Central Europe, Africa, and Latin America. Second, we test whether these indices are governed by economic and cultural factors. Our results show that the spillover effects vary across markets and that a strong correlation exists with the volume of trade, security investment, common language, distance, and market capitalization.     

The impact of business and political news on the GCC stock markets

This paper investigates the impact of business and political news on stock market returns in the Gulf Cooperation Council (GCC) countries. For this purpose, it employs a Markov switching model including a separate index for each of the two categories of news considered. The results indicate the importance of news as drivers of GCC stock returns, with business news playing a more substantial role; further, news released in the largest financial markets in the regions are found to have significant cross-border effects.     

The global financial crisis and integration in European retail banking

The aim of this paper is twofold. Firstly, to investigate the integration process within the European Union retail banking sector by analysing deposit and lending rates to the household sector during the period 2003–2011. Secondly, to assess the impact of the 2008 global financial crisis on the banking integration process, an area that is yet unexplored. An important contribution of the paper is the application of the recently developed Phillips and Sul (2007a) panel convergence methodology which has not hitherto been employed in this area. This method analyses the degree as well as the speed of convergence, identifies the presence of club formation, and measures the behaviour of each country’s transition path relative to the panel average. The empirical results point to the presence of convergence in all deposit and lending rates to the household sector up to 2007. In sharp contrast, the null of convergence is rejected in all deposit and credit markets after the onset of the 2008 financial crisis. These results show that the global crisis has had a detrimental effect on the banking integration process. We find some convergence in a few sub-clusters of countries but the rate of convergence is typically slow and several countries are identified as diverging altogether. In addition, we find that the credit market, in general, is far more heterogeneous than the savings market.     

Can advanced markets help diversify risks in frontier stock markets? Evidence from Gulf Arab stock markets

This study examines global diversification benefits from the perspective of local investors in the frontier markets in the Gulf Cooperation Council using two diversification measures: the correlation index and return dispersion. The findings suggest a strong link between market volatility and both diversification measures in all markets, with the exception of Bahrain, indicating that investors in these frontier markets will face significant challenges achieving desired levels of diversification using domestic stocks only. However, I also find that significant amount of market risk in these countries can be eliminated by supplementing domestic portfolios with positions in advanced markets. Finally, I show that risk minimization strategies using foreign traded assets also lead to favorable risk adjusted returns for investors in these markets, stressing the potential benefits of financial liberalization in developing markets.     

Integration in European retail banking: Evidence from savings and lending rates to non-financial corporations

The aim of this paper is to investigate the integration process in the European Union retail banking sector during the period 2003–2011, by analysing deposit and lending rates to non-financial corporations. An important contribution of the paper is the application of the recently developed Phillips and Sul (2007a) panel convergence methodology which has not hitherto been employed in this area. This method analyses the degree as well as the speed of convergence, identifies the presence of club formation, and measures the behaviour of each country's transition path relative to the panel average. In addition, this is the first empirical paper that analyses the impact of the 2008 global financial crisis on the European retail banking integration process. The empirical results point to the presence of convergence in all deposit and lending rates to non-financial corporations up to 2007. In contrast, the null of convergence is rejected in all deposit and credit markets after the onset of the 2008 financial crisis. Although we still find slow convergence in a few sub-clusters of countries, the transition paths become very divergent, with the credit market being far more heterogeneous than the savings market.     

Does Cross-Listing Benefit the Shareholders? Evidence from Companies in the GCC Countries?

The goal of this study is to estimate the impact of cross-listing on stock returns, on liquidity, and on risk. A sample of 24 companies from the Gulf Cooperation Council countries which cross-listed their stocks in a foreign market over the period 2000–2010 were chosen for study. An event study estimating abnormal returns related to the cross-listing event as well as parametric and nonparametric tests find that there is (1) a significant abnormal return of about 6 % that lasts until 6 days after the cross-listing day and starts fading away thereafter (2) a significant increase in liquidity during the event period for most firms and (3) on average a decrease in risk. Our results also suggest that cross-listing had a small impact on market risk measured by the average beta but led to a decrease in the total risk measured by standard deviation of returns and a decrease in the potential loss measured by the average value at risk at the 5 % confidence. Additionally, an analysis based on the foreign market of secondary listing suggests that the benefit of cross-listing varies with the market of secondary listing. The positive abnormal return is more obvious for companies that cross-listed in Kuwait, Bahrain, and London. The most obvious increase in liquidity is for firms that cross-listed in London or in Bahrain and the biggest decrease in risk is for companies that cross-listed in London. We conclude overall that cross-listing in London benefits the shareholders the most as it leads to positive significant abnormal returns, an increase in liquidity, and a decrease in risk.     

Bank efficiency,productivity, and convergence in EU countries: a weighted Russell directional distance model

The objective of this study is three-fold. First we estimate and analyse bank efficiency and productivity changes in the EU28 countries with the application of a novel approach, a weighted Russell directional distance model. Second, we take a disaggregated approach and analyse the contribution of the individual bank inputs on bank efficiency and productivity growth. Third, we test for convergence in EU28 bank productivity as well as in the inefficiency of individual bank inputs. We find that bank efficiency has been undermined by the financial crisis in banks notably from the EU15 countries. We also argue that bank efficiency and productivity in EU countries vary across the banking sector with banks from the ‘old’ EU showing higher efficiency levels. Nonetheless, a noticeable catching up process is observed for banks from the ‘new’ EU countries. Consequently, we do not find evidence of group convergence for bank productivity but there is evidence of convergence in bank efficiency change and technical change among the EU28 countries throughout the period 2005–2014. The driving force seems to be convergent technical change from the old EU member states’ banks. On the other hand, almost no convergence is detected for the banks’ individual inputs while the transition paths show heightened diversity during the crisis years.     

Bank efficiency in the new European Union member states: Is there convergence?

We employ the stochastic frontier approach and estimate a common frontier in order to examine cost and profit efficiency in the banking systems of the ten new European Union member states over the period 1998-2003. The results indicate a generally low level of cost and an even lower level of profit efficiency, whilst we do not observe marked differences of inefficiency scores across countries. Foreign banks outperform both state-owned and domestic private-owned banks in terms of profit efficiency, though results are less clear in the case of cost efficiency. In addition, β- and σ-convergence criteria indicate some convergence in cost efficiency across the new member states, yet no convergence appears to have been achieved in terms of profit efficiency.

Diffusion of Management Accounting Practices in Gulf Cooperation Council Countries*

This study examines how management accounting practices (MAPs) have been adopted and diffused by publicly listed firms in the Gulf Cooperation Council (GCC) countries. The results of our survey show that the adoption rates for MAPs in the area of cost management and strategy are low while those in the area of performance measurement are moderate. Overall, the respondents favorably perceived their success in implementing MAPs. Power and politics, not economic (or cost–benefit) reasons, were considered to be the most influential reasons for nonadoption of MAPs. The results provide partial support to the view that there is a global convergence of management accounting system designs and ideas and also indicate that the role of cultural differences is diminishing over time.     

Using accounting ratios to distinguish between Islamic and conventional banks in the GCC region

This study determines whether it is possible to distinguish between conventional and Islamic banks in the Gulf Cooperation Council (GCC) region on the basis of financial characteristics alone. Islamic banks operate under different principles, such as risk sharing and the prohibition of interest, yet both types of banks face similar competitive conditions. The combination of effects makes it unclear whether financial ratios will differ significantly between the two categories of banks. We input 26 financial ratios into logit, neural network, and k-means nearest neighbor classification models to determine whether researchers or regulators could use these ratios to distinguish between the two types of banks. Although the means of several ratios are similar between the two categories of banks, non-linear classification techniques (k-means nearest neighbors and neural networks) are able to correctly distinguish Islamic from conventional banks in out-of-sample tests at about a 92% success rate.     

Inter- and intra-regional stock market relations for the GCC bloc

This paper examines the patterns of information transmission for equity markets in the seven Gulf Cooperation Council countries over the period from 2004 to 2019. Using weekly data, correlations and spillovers both within the region and from the US, the EU and Japan are modelled through the Dynamic Conditional Correlation-GARCH model and the Diebold-Yilmaz spillover index. While GCC markets exhibit increasing correlations with, primarily, the EU and, to a lesser extent, the US, they nonetheless remain relatively less interlinked globally. Our findings support significant return and volatility spillovers from the EU and the US to the GCC markets, with stronger spillovers from the EU. Intra-regionally, the UAE is the main transmitter and receiver of spillovers between the GCC and world markets. Furthermore, we see evidence of a decoupling pattern within the GCC countries, with notable segmentation in the markets of Bahrain and Kuwait.     

The Impact of Liquidity on Debt Maturity After a Financial Crisis: Evidence from the Gulf Cooperation Council Region

This article contributes to the existent literature on corporate debt maturity by studying a new channel through which firms may mitigate the effects of a major economic downturn such as the 2008 global financial crisis. More specifically, using a sample of 208 listed firms in the Gulf Cooperation Council (GCC) region, we find that an increase in firms’ current ratios after the crisis is associated with an increase in long-term financing. We also find that a financially constrained firm can still access long-term financing if its current ratio after the crisis is beyond a specific threshold. Additionally, we highlight the differences in the typical drivers of debt structure between GCC countries and industries.
