Cost and profit efficiency of conventional and Islamic banks in GCC countries

Using stochastic frontier approach, this paper investigates the cost and profit efficiency levels of 71 commercial banks in Gulf cooperation council countries over the period 1999–2007. This study also conducts a comparative analysis of the efficiency across countries and between conventional and Islamic banks. Moreover, we examine the bank-specific variables that may explain the sources of inefficiency. The empirical results indicate that banks in the Gulf region are relatively more efficient at generating profits than at controlling costs. We also find that in terms of both cost and profit efficiency levels, the conventional banks on average are more efficient than Islamic banks. Furthermore, we observe a positive correlation of cost and profit efficiency with bank capitalization and profitability, and a negative one with operation cost. Higher loan activity increases the profit efficiency of banks, but it has a negative impact on cost efficiency.     

Do Pan-African banks have the best of both worlds?

There has been a large expansion of foreign banks in Africa over the last two decades, with Pan-African banks playing a key role in this phenomenon. This paper questions if this development is beneficial for bank efficiency in African countries by investigating if Pan-African banks are more efficient than other types of foreign and domestic banks. We analyse the relation between ownership type and bank efficiency on a large sample of African banks covering 39 African countries over the period 2002–2015. We find that Pan-African banks are the most efficient banks in the African banking industries. We explain this finding with the fact that these banks combine the best of both worlds: they have the global advantages of foreign banks and the home field advantages of domestic banks. They are therefore able to be more efficient than both foreign banks from developed countries and domestic banks. This suggests that favouring the entry of Pan-African banks would be beneficial to bank efficiency in Africa.     

Inefficiency and heterogeneity in Turkish banking: 1990–2000

Recent studies have stressed the importance of privatization and openness to foreign competition for bank efficiency and economic growth. We study bank efficiency in Turkey, an emerging economy with great heterogeneity in bank types and ownership structures. Earlier studies of Turkish banking had three limitations: (i) excessive reliance on cost‐function frontier analyses, wherein volume of loans is a measure of banking output; (ii) pooling all banks or imposing ad hoc heterogeneity assumptions; and (iii) lack of a comprehensive panel data set for proper analysis of productivity and heterogeneity. We use an estimation–classification procedure to find likelihood‐driven classification of bank technologies in an 11‐year panel. In addition, we augment traditional cost‐frontier analysis with a labour‐efficiency analysis. We conclude that state banks are not particularly inefficient overall, but that they do utilize labour inefficiently. This partially supports recent calls for privatization. We also conclude that special finance houses (or Islamic banks) utilize the same technology as conventional domestic banks, and do so relatively efficiently. This suggests that they do not cause harm to the financial system. Finally, we conclude that foreign banks utilize a different technology from domestic ones. This suggests that one should not overstate their value to the financial sector. Copyright © 2005 John Wiley & Sons, Ltd.

Monetary policy and asset prices in an open economy

This paper examines whether central banks should respond to asset price fluctuations in a two-country sticky price model. We compare a monetary policy rule that targets both domestic asset prices and foreign asset prices with several alternative monetary policy rules. This paper shows that this policy rule can produce preferable outcomes because the domestic central bank incorporates important information that both domestic and foreign asset prices possess into its monetary policy. Our model suggests that central banks should consider both domestic and foreign asset prices in a two country framework with asset price fluctuations.     

Banking efficiency in South East Europe: Evidence for financial crises and the gap between new EU members and candidate countries

In this study we compare the cost efficiency of banks in ten South East European countries and find out how differences in efficiency are related to EU membership. The results reveal a statistically significant cost efficiency gap between EU and non-EU banking systems in the region, where on average EU banking systems tend to be more cost efficient than their non-EU counterparts. In contrast to other similar studies analyzing banking efficiency in South East European countries, we also run β-convergence and σ-convergence tests, as proposed in the literature. Based on these tests we can draw conclusions concerning the existence of a catching-up effect, since the detected cost efficiency gap is closing predominantly because of adjustments on the side of the less efficient banks. Additionally, we found that during the 2008 global financial crisis, the average cost efficiency scores of banks in the region improved, which could be explained by enhanced incentives of bank managers for intensified cost optimization in banks in crisis times. Our results suggest that the institutional adjustments in the non-EU countries should continue towards EU standards, as the EU banking systems tend to dominate in terms of measured cost efficiency.     

Measures to tame credit growth: Are they effective?

This paper focuses on policy measures taken to curb bank credit growth in the private sector in the pre-crisis period 2003–2007. Our analysis is based on an original survey conducted in 2010 on eleven central banks in Central and Eastern Europe (CEE). The findings reveal substantial policy intervention: a total of 82 measures were implemented in CEE during the period considered. The paper presents a panel data analysis of the effectiveness of the policy measures adopted in the region. The overall results indicate that certain measures – particularly asset classification and provisioning rules and loan eligibility criteria – might have been effective in taming bank credit growth, especially if applied in the context of more general policy measures featuring a combination of various instruments. However, in countries in which the authorities managed to somewhat decrease the flows of bank credit into the economy, the measures were often circumvented via direct, cross-border credit from foreign banks and credit provided by domestic, non-bank financial companies.     

Asymmetric information,foreign entry and multi-period credit competition in banking industry

In a credit market, a low-cost foreign entrant is likely less informed than a domestic bank with information endowments. We present a steady-state model in an infinite-period framework, and analyze how the informational asymmetry affects the lending equilibrium and the foreign banks’ entry modes. Firstly, we show that the domestic bank's initial informational advantage from its relatively large market share at the beginning of competition is not enough to hinder the entry of a low-cost foreign bank. In addition, the foreign bank is more likely to be the winner in the steady state of an infinite-period game than that in a static game. Secondly, the comparative static analysis show that the likelihood of foreign bank becoming the winning party increases with borrower quality, project payoff and the growth rate of potential new borrowers. Thirdly, when the foreign bank wins game in the steady state, its market share is decreasing in project payoff and the growth rate of new borrowers, while changes non-monotonically with borrower quality. Finally, we extend our model to characterize the domestic bank's sustainable advantage in being relatively familiar with new market, and provide valuable explanations for the observed entry modes of foreign banks in China.     

An examination of the cost efficiency of banks in Taiwan and China using the metafrontier cost function

Using the stochastic metafrontier framework of Battese et al. (J Prod Anal 21:91–103, 2004), this study proposes to compare and measure the cost efficiency and cost frontier gap between the banking industry in Taiwan and China. It further identifies environmental variables that determine bank’s cost frontier gap between two countries. Data on 69 sample banks for years 2005–2009 are used in the empirical analysis and inference. The empirical results show that Taiwanese banks have in general the superior cost frontier of production, but inferior cost efficiency of operation than Chinese banks. Private banks in Taiwan have the best cost frontier, whereas foreign banks in China are most cost efficient among all banks in Taiwan and China. The empirical results also reveal that the majority of Taiwanese banks are undersized and that most banks in China are oversized. Finally, the regression results show that the financial market structure, institutional environment, and political development are significant determinants of the cost gap between the cost frontiers of banks in Taiwan and China. Therefore, programs related to changes directed toward a better bank production environment can be initiated to improve the cost technologies of banks in both Taiwan and China.     

The effect of scale and mode of ownership on the financial performance of the Turkish banking sector: results of a DEA-based analysis

Turkey and the International Monetary Fund (IMF) agreed to a stand-by arrangement at the outset of 2000. Consequently, Turkey implemented an exchange-rate based stabilization program to combat its high inflation. However, two financial crises followed: one in November, 2000 and the other in February, 2001. As the result some banks became problematic. This necessitated restructuring of the banking sector to increase its financial efficiency.This paper presents a financial performance index for commercial banks. The index allows one to observe the effects of scale and of the mode of ownership (public/domestic, private/domestic/foreign) on bank behavior and, therefore, on bank performance in a developing economy. It documents the effects of financial liberalization, cross-country movements, and the impact of financial crises originating in neighboring countries e.g. Russia. The study applies Data Envelopment Analysis (DEA) to selected fundamental financial ratios using 1989-99 data from commercial banks in Turkey. Year-by-year results explain the effects on this sector of major shifts in both national macro-economic policy and various international developments. The banks that were taken over by the regulatory government agency most recently in the analyzed period were observed to perform poorly with respect to their DEA performance index values.     

Efficiency and productivity of the US banking industry, 1998–2005: evidence from the Fourier cost function satisfying global regularity conditions

This paper provides estimates of bank efficiency and productivity in the United States, over the period from 1998 to 2005, using (for the first time) the globally flexible Fourier cost functional form, as originally proposed by Gallant ( 1982 ), and estimated subject to global theoretical regularity conditions, using procedures suggested by Gallant and Golub ( 1984 ). We find that failure to incorporate monotonicity and curvature into the estimation results in mismeasured magnitudes of cost efficiency and misleading rankings of individual banks in terms of cost efficiency. We also find that the largest two subgroups (with assets greater than 1 billion in 1998 dollars) are less efficient than the other subgroups and that the largest four bank subgroups (with assets greater than $ 400 million) experienced significant productivity gains and the smallest eight subgroups experienced insignificant productivity gains or even productivity losses.

Consolidation in the European banking industry: how effective is it?

The European banking industry is becoming increasingly consolidated as banks engage in domestic and cross-border merger and acquisition (M&A) activities. Due to cultural differences in cross-border consolidations, the benefits of domestic and cross-border consolidations are likely to differ. This paper examines the effectiveness of merger processes, with a detailed analysis of both domestic and cross-border consolidations in Europe from 1998 to 2004. Effectiveness is measured via several criteria: improvement in costs, return on assets (ROA), and return on equity (ROE). To analyze potential cost efficiency improvement, we use a stochastic cost frontier approach. The same methodology is used for ROA and ROE to estimate efficiency in profitability. Finally, considering cross-border mergers as a form of entry, we carry out an analysis of the entry effect in response to the performance and profitability of the incumbent market participants. Results show that mergers in the European banking industry have been effective. Although domestic M&As are more common than cross-border M&As, banks involved in cross-border M&As are more efficient. Moreover, cross-border merged banks seem to outperform incumbent banks.     

Estimating banking cost efficiency with the consideration of cost management

This study re-investigates the bank cost efficiency by a combination of two strands of literature. The first strand is related to bank cost efficiency; the other is related to earnings management. Employing the findings reported in bank earnings management literature, this study argues that bank observed total cost (“accounting cost”) may be the biased estimator of the true total cost. Using the biased total cost may thus yield incorrect inferences from estimating bank cost efficiency. We propose a method to modify accounting cost, which is referred to as “economic cost”, to be consistent with the economic theory; that is, one that is free of cost management. Both accounting and economic costs are then adopted to analyze the efficiency of 29 commercial banks in Taiwan banking industry. Our results show that estimated efficiency, with the application of economic cost, offers results that are more reasonable results than those of the accounting cost.     

Bank Cost Efficiency and Output Specification

There is a longstanding controversy over precisely what it is that banks produce. However, there is little evidence on the sensitivity of bank cost efficiency results when different output definitions are applied. This paper does exactly that. In particular, we compare nonparametric efficiency scores yielded by two output specifications, one mainly identified with the asset approach and the other which also considers deposits as output. Results show that distributions of efficiency scores, estimated nonparametrically by means of kernel smoothing, vary greatly. In addition, firms' positions relative to the mean change according to either output definition, and results do not remain constant over time.     

Does bank capitalization matter for bank stock returns?

We examine US bank capitalization and its association with bank stock returns, and find that the book- and market-based capital ratios show different patterns. Fama-MacBeth regressions and portfolio analyses suggest that banks’ market-based capital ratios are negatively associated with banks’ stock returns during the (tranquil) 1994–2007 period while book-based capital ratios are positively associated with banks’ stock returns during the (turbulent) 2008–2014 period. These results suggest that the effect of bank capitalization on bank stock returns depends on the capital measure used and the period considered.     

The impact of the macroeconomic factors in the bank efficiency: Evidence from the Chinese city banks

This study uses stochastic frontier analysis to examine the impact of the regional disparities in the cost and profit efficiency for a sample of city commercial banks in China from 2005 to 2014. The results indicate that bank efficiency of Chinese City Commercial banks is positively correlated to the per capital GDP but negatively linked to urban population ratio. However, compared the eastern and non-eastern regions, there is a significant difference in effects of macroeconomic factors for bank efficiency. The macroeconomic conditions influence the efficiency of Chinese City Commercial banks in eastern regions are more significant than the others.     

Measuring the impact of restructuring and country-specific factors on the efficiency of post-crisis East Asian banking systems: Integrating DEA with SFA

This paper investigates the relationship between post-crisis bank restructuring, country-specific conditions and bank efficiency in Asian countries from 1997 to 2001 using an approach that integrates data envelopment analysis and stochastic frontier analysis. We focus on restructuring measures related to bank ownership. The results indicate that although domestic mergers produce more efficient banks, overall, restructuring does not lead to more efficient banking systems. Banking system inefficiencies are mostly attributed to country-specific conditions, particularly, high interest rates, concentrated markets and economic development.     

Cost efficiency of the banking industry and unilateral euroisation: A stochastic frontier approach in Serbia and Montenegro

This paper aims at investigating the differences in cost efficiency of the banking industry in Serbia and Montenegro over the period 2005–2012. These two countries operated under a common monetary regime until 1999 and followed two different monetary regimes thereafter: unilateral euroisation in Montenegro and monetary independence in Serbia. A stochastic frontier approach incorporating bank-specific and country-related variables is used to analyze cost efficiency in the banking sectors of Serbia and Montenegro. The analysis shows that a bank operating at given conditions in terms of ownership, market and other specific characteristics presents significantly higher cost efficiency if it operates in Montenegro rather than in Serbia. We argue that this result may relate to the choice of unilateral euroisation made by Montenegro. It is also shown that foreign-owned banks, higher capitalized banks and banks with lower non-performing loans operate at higher cost efficiency.     

On bank privatization: The case of Egypt

This paper discusses the controversy regarding the privatization of the banking sector in Egypt. It provides an overview of the structure and evolution of the banking system, in the context of the series of reform measures undertaken by the Egyptian authorities over the past decades. The paper assesses the performance of the state-owned banks versus private banks over the period 1995–2005. Microprudential indicators, such as capital adequacy, asset quality, earnings, and profitability, reveal that state-owned banks lag behind in terms of efficiency and performance, compared to their private counterparts. Results also suggest that retaining government ownership can adversely affect banks performance. The paper explores the factors hindering the smooth implementation of bank privatization. The authors indicate that the financial sector reform currently adopted is comprehensive; however it is confronted with various political, social, and economic risks, which raise concerns regarding its sustainability. The paper then draws on the existing literature to provide guidance to policy makers, regarding effective and successful implementation of bank privatization.     

市场势力对银行效率影响分析——来自我国商业银行的经验数据

运用我国14家上市和50家未上市商业银行2000~2009年的数据探讨商业银行市场势力对效率的影响。分别测量我国商业银行的市场势力、成本效率以及利润效率,结果发现与未上市商业银行相比,上市商业银行具有较高的市场势力和利润效率以及较低的成本效率。同时分别建立线性模型和非线性模型分析市场势力对效率的影响,结果发现在我国特殊金融环境下,商业银行市场势力与成本效率或利润效率之间均为线性关系;提高商业银行的市场势力,会导致其成本效率显著下降和利润效率显著提升;在所有显著的变量中,信用风险对成本效率和利润效率的影响都是最大的。
