DEA efficiency profiles of U.S. banks operating internationally

Data envelopment analysis (DEA) was used to analyze the 1987 and 1992 input/output efficiency of U.S. banks operating internationally. In 1987, banks belatedly began to acknowledge with huge writeoffs the crisis in lending to less-developed countries (LDCs). Some 20% of the banks were identified as inefficient in each year, and approximately 50-60% of the total inputs/outputs of inefficient banks were excessive/deficient, with inputs proportionately more so than outputs. In 1987, the herd instinct that had led to the LDC loan crisis caused DEA's empirical “best practice” production frontier to identify as efficient banks that were financial “bad practice” banks. However, by 1992, normalcy had returned and DEA best practice banks were also financial good practice banks. Overall, it was found that management should focus on overall efficiency, but with particular attention to inputs, especially cash and real capital, and to foreign loans among the outputs.     

The impact of earnings management on the performance of ASEAN banks

Southeast Asian financial liberalization policies have enthused both performance evaluation (a pro) and earnings management (a con). Using a sample of ASEAN commercial banks for the period 2007–2014, this study decomposes their banking performance into managerial and profitability efficiencies. An efficiency analysis reveals that Singaporean banks obtained the highest overall and profitability efficiencies, while Bruneian banks had the lowest rates of banking performance. In the stage of managerial efficiency, the most inefficient banks are those of the Philippines, whereas the greatest level is related to Malaysian banks. A frontier projection analysis suggests that Singaporean banks and Malaysian banks are generally more efficient in managing their expenditures and long-term assets in generating income in the long run. With respect to the con, a regression analysis indicates that loan loss provisions are negatively related to banking performance. Overall, it is advisable that policy makers with oversight function should promote performance evaluation from a multidimensional perspective, and keep an eye on estimates of loan loss provisions at banks over years because increases/decreases in loan loss provisions mean decreases/increases in net income or return on assets.     

Enterprise life cycle,financial technology and digital transformation of banks—Evidence from China

Financial technology formed by the combination of digital technology and traditional finance is gradually changing the financial services model. The development of financial technology has influenced the behaviour of commercial banks. It has promoted the innovation of commercial banks. And it has promoted the digital transformation of commercial banks. In this paper, it is intended to explore the relationship between financial technology and digital transformation of banks through positive analysis. As well as to explore how the age of enterprises listed and enterprise life cycle affect the relationship between financial technology and digital transformation of banks. This paper conducts an empirical research on the data of China's A-share listed banks from 2011 to 2021 using a two-way fixed effects regression method. The results of the research indicate that financial technology promotes banks' digital transformation. Meanwhile, the age of enterprise listing and enterprise life cycle play a positive moderating role in financial technology promoting banks' digital transformation. In this paper, it is the first time to conduct an empirical research with the number of monthly active users of mobile banking as a proxy variable for digital transformation of banks, which enriches the study of financial technology. It has certain reference value for promoting digital transformation of banks.     

TO JOIN OR NOT TO JOIN? DO BANKS THAT ARE PART OF A FINANCIAL HOLDING COMPANY PERFORM BETTER THAN BANKS THAT ARE NOT?

This study compares the performance of banks that are part of a financial holding company (FHC banks) with that of banks that are not (independent banks) using Taiwan data from 2002:Q1 to 2006:Q2. The comparisons are based on 14 performance ratios resulting from the concept of CAMEL (which is an acronym for Capital adequacy, Asset quality, Management efficiency, Earnings ability, and Liquidity sufficiency). To ensure that becoming part of an FHC is a random process, we used four matching methods to select the controlled banks so that the characteristic variables of banks in the two groups are statistically indifferent. By using the data before matching, it was found that FHC banks significantly defeat independent banks, regardless of their performance ratios. Conversely, when the sample was used after the matching, the results changed dramatically. Although FHC banks still beat the independent banks in terms of capital adequacy, asset quality, and liquidity sufficiency, FHC banks and independent banks are found to have equal profitability and management efficiency. Earlier studies that do not consider the endogeneity problem tend to overestimate the joining effect.(JEL C21, G21)     

Evaluating Efficiency of Personnel in Nepalese Commercial Banks

The failure of large and reputable banks is creating a potential threat to depositors’ hard-earned money deposited in commercial banks (CBs). Therefore, evaluation of the risk-adjusted efficiency of CBs is crucial. This study evaluates the relative efficiency of CBs personnel with an unbalanced panel dataset of 21 Nepalese CBs based on their remunerations, financial performances, and risky behaviors using data envelopment analysis, the Malmquist productivity index, and simple regression analysis. In the first step analysis, various financial ratios regarding the firm performance were considered. In the second step analysis, efficiency scores estimated in the first step analysis were adjusted by risk variables. The study shows that relatively large banks were exploiting personnel expenses, but smaller-sized banks, recently established banks, and banks with fewer branches gained more efficiency from their size. Personnel efficiency had a positive influence on the market price of stock, but it also increased the volatility of stock prices. Negative growth of both productivity indices (i.e., with and without risk adjustment) suggests poor agency services delivered by personnel and decreasing healthy conduct of Nepalese CBs.     

Bank overall financial strength: Islamic versus conventional banks

A number of recent studies compare the performance of Islamic and conventional banks with the use of individual financial ratios or efficiency frontier techniques. The present study extends this strand of the literature, by comparing Islamic banks, conventional banks, and banks with an Islamic window with the use of a bank overall financial strength index. This index is developed with a multicriteria methodology that allows us to aggregate various criteria capturing bank capital strength, asset quality, earnings, liquidity, and management quality in controlling expenses. We find that banks differ significantly in terms of individual financial ratios; however, the difference of the overall financial strength between Islamic and conventional banks is not statistically significant. This finding is confirmed with both univariate comparisons and in multivariate regression estimations. When we look at the bank financial strength within regions, we find that conventional banks outperform both the Islamic banks and the banks with Islamic window in the case of Asia and the Gulf Cooperation Council; however, Islamic banks perform better in the MENA and Senegal region. Second stage regressions also reveal that the bank overall financial strength index is influenced by various country-specific attributes. These include control of corruption, government effectiveness, and operation in one of the seven countries that are expected to drive the next big wave in Islamic finance.     

Banking efficiency in transition economies

An increasing share of the banking sector is controlled by foreign capital in the majority of transition countries. To analyse the effects of this trend on the performance of the banking sector in these countries, this study conducts a comparative analysis of the performance of foreign‐owned and domestic‐owned banks operating in the Czech Republic and Poland. We use the stochastic frontier approach to compute cost efficiency scores. Following Mester (1996 ), financial capital is included in the cost frontier model to control for risk preferences. Our finding is that on average foreign‐owned banks are more efficient than domestic‐owned banks. We conclude, however, that this advantage does not result from differences in the scale of operations or the structure of activities.     

Banks’ non-traditional activities under regulatory changes: impact on risk,performance and capital adequacy

Using the big six Canadian chartered banks quarterly financial statements and daily stock market data from 1982 to 2018, we examine the impact of non-interest income on Canadian banks’ risk, performance and capital under the different major regulatory changes made to the Bank Act of Canada. Our results show that Canadian banks’ expansion into non-traditional activities had slightly decreased their risks and significantly improved their performance benefitting from income diversification. Moreover, while adhering to capital adequacy regulation, reshuffling banks’ portfolio towards non-traditional activities did not reduce Canadian banks’ capital ratio. In spite of the re-regulation towards universal banking against ring-fencing, this feature buttresses the effectiveness of capital adequacy regulation in Canada in linking banks capital allocation with their risk taking.     

ANALYSIS OF THE POSSIBILITIES FOR EXPANSION OF SERVICES IN TANZANIAN SAVINGS AND CREDITS CO‐OPERATIVE SOCIETIES: LEARNING FROM ECONOMIES OF SCALE

Savings and Credit Co‐operative Societies (SACCOS) increasingly recognized as the valuable tool for economic development in low‐income countries. However, recently researchers reported that one of their primary challenges to their expansion is the high level of inefficient. In this study, we analyzed the relationship between growth and efficiency of SACCOS using economies of scale concept. Then we address the role of management of the capital structure and allocation of resources in the expansion of SACCOS. The study used financial statement data from 60 SACCOS in Tanzania for the period of 2004–2011. The findings supports that most of SACCOS are small and cost inefficient because the industry is young, but, the efficiency increases as SACCOS expand. Second the allocation of resources in liquid, financial and non‐financial investment leads to no expansion in SACCOS. Thus, the growth of SACCOS via increasing loan to members, members’ savings, shares, and institutional capital should be encouraged as it increases the efficiency of SACCOS. Also, SACCOS should minimize the allocation of assets in other investments which are different from credit to members.     

Cyclical behavior of the financial stability of eurozone commercial banks

In light of the financial crisis and the European sovereign debt crisis, we investigate the cyclical behavior of the financial stability of banks of the Eurozone, using an unbalanced dynamic panel of 722 commercial banks covering the period 1999–2013, and the generalized method of moments system. We find a negative relationship between business cycle and bank risk-taking, indicating that financial stability is procyclical. In addition, the study shows that lending activity increases risk-taking while rising capital requirements boost financial stability. Moreover, our findings suggest positive co-movements between the business cycle and lending, compared to bank's capital, whereby the procyclicality of lending and bank capital have negative effects on the financial stability of commercial banks in the Eurozone. We notice then that the cyclical behavior of commercial banks, in terms of capital requirements and lending activities, depends on their size. Therefore, lending and capital of smaller banks are procyclical while lending and capital of larger banks are countercyclical. Finally, we find the Troika institutions’ bailouts programs significantly impacted banking stability in the Eurozone.     

金融危机、货币政策与信贷供给*——基于公司层面银行信贷数据的经验研究

不同的银行特征会对金融危机和货币政策传导的银行信贷渠道产生异质性影响。本文运用2001-2015年公司层面银行信贷数据实证检验了我国货币政策传导的银行信贷渠道,随后进一步研究金融危机对不同特征银行信贷供给的影响差异。经验研究发现：我国货币政策银行信贷渠道主要通过非国有控股银行传导,并引起不同资产负债表特征银行信贷供给的异质性反应。银行规模越大、流动性越强、资本充足率越高,银行信贷供给对货币政策越不敏感。金融危机期间,银行信贷渠道的传导效率显著降低,高资本充足水平的银行和国有控股银行受金融危机的冲击较小,并且宽松的货币政策对国有控股银行信贷供给调控的效率更高。     

Intellectual capital and university performance in Taiwan

Assessing university performance is an important yet complex issue. Knowing whether policy is effective in achieving its goal of advancing teaching and research is critical. Furthermore, at the level of implementation, it is necessary to understand if university resource allocation is sufficiently efficient for delivering expected results. To achieve this insight, this study utilizes a two-stage data envelopment analysis to evaluate the cost and teaching and research efficiencies of public universities in Taiwan. Additionally, this paper also employs a truncated-regression to discuss whether intellectual capital affects the operating efficiency of universities. The results demonstrate that the universities are much better at handling cost efficiencies than teaching and research efficiencies. The regression analysis indicates that intellectual capital does play an important role in influencing teaching and research efficiency. Finally, the conceptual roadmap to performance improvement strategies, which helps the manager and/or authorities to improve their operating efficiencies, also is presented.     

我国商业银行效率分析——基于超效率DEA和Malmquist指数

效率是银行经营管理的核心,是银行竞争优势的集中体现,尤其在后危机时代,提高银行业的效率也是防范金融风险,实现可持续发展的关键。本文基于超效率DEA方法,运用EMS软件对2004—2009年14家商业银行的效率进行分析,对其均值进行排名;并通过Malmquist指数对银行效率进行分解研究,重点分析金融危机前后的商业银行全要素生产率的变化趋势。结果表明,效率水平总体呈现上升趋势,这与社会经济的发展是相一致的。而四大国有银行的效率不及股份制商业银行,可见,四大国有银行并没有因为资产规模大,而带来更高的收益和绩效;2004—2009年商业银行全要素生产率整体上不断提高,主要得益于技术进步和规模效益,但2009年全要素生产率有所下降,受美国金融危机全面升级所导致的国际国内经济发展衰退的影响,经营风险加大,息差收窄,对银行盈利和效率产生不利影响。     

Deposit insurance and moral hazard problem: the case of Turkish banking system

We investigate the effect of full deposit insurance introduced in 1994 on the financial performance of Turkish commercial banks. We construct a model, under reasonable assumptions, with deposit insurance where banks undertake excessive risk –?moral hazard risk. Empirical investigation using experimental design approach supports our moral hazard hypothesis. Our findings indicate that banks subject to the moral hazard behaviour show significant increases in foreign exchange position risk and deterioration in capital adequacy relative to their benchmark after introduction of full deposit insurance system. We relate this excessive risk-taking to the moral hazard behaviour by commercial banks. The research results indicate that complete deposit insurance system distorts the incentive structure of commercial banks and thus, prevents proper functioning of market discipline mechanism and leads to the taking excessive risk-taking.     

金融结构、创新模式与技术创新效率

技术创新的研发和转化离不开金融支持。本文从创新价值链和创新模式出发,构建金融结构、技术创新模式与技术创新效率的理论分析框架,基于三阶段DEA-Tobit模型和广义分位数回归模型,实证分析金融结构对技术创新模式转变、技术创新效率影响。研究发现,我国技术创新研发和转化两个阶段的规模效率较低,导致研发综合效率和转化综合效率存在“双低”现象。从金融结构来看,存在着最佳的金融结构与不同类型技术创新相匹配,使技术创新效率达到最大。从影响机制来看,银行和金融市场存在互补关系,分别匹配不同类型的技术创新。从金融结构分工来看,相对于银行来说,金融市场对技术创新效率以及技术创新模式转变的重要性呈现上升趋势。     

Large lending and banks performance. Is there any relationship? Empirical evidence from US banks

Large lending in the banking industry has sparked concerns about banks’ efficiency performance, particularly, if it is related to their credit risk, as trade credit, provided by large, creditworthy firms. We provide evidence of a rather neglected issue regarding the impact of large lending on banks’ efficiency using cost and profit stochastic functions. A unique dataset was constructed concerning all US banks collected from the Statistics on Depository Institutions report compiled by the Federal Deposit Insurance Corporation. Our sample contains US banks tracked yearly for the period 2010–2017, creating an unbalanced panel of year observations. An econometric framework based on nested non-neutral frontiers was developed to estimate the influence and the decomposition of large lending on the three banks’ performance aspects. Moreover, different types of frontiers aiming at the cost and profit sides have been investigated, and the associated elasticities have been calculated. We notice that large lending plays a crucial role in banks’ technical efficiency. Variations among different frontier models, type of bank and size, banks’ ownership structure, and macroeconomic conditions appear to be present. By considering all capital adequacy asset quality management earnings liquidity parameters, we notice that banks’ financial strength affects banks’ efficiency.

ANALYSIS OF POVERTY AND EFFICIENCY: AN EARNINGS FRONTIER APPROACH

The paper introduces the concept of an earnings frontier in explaining monthly consumption expenditure (a proxy for income) in terms of human capital and endowments of a household. Individuals who translate their potential earning into actual earnings enjoy a fully efficient position. In contrast, individuals who earn less than their potential earnings suffer from some kind of earnings inefficiency. The paper estimates an earnings frontier using the Corrected Ordinary Least Square (COLS) method and classifies households in terms of efficiency scores. Splitting the sample into an efficient and an inefficient part based on the estimated frontier and a bench mark efficiency score, the status of poverty in the two parts (groups) is studied. The poverty gap between the groups is then decomposed into a characteristics effect and a coefficients effect using the familiar Oaxaca decomposition methodology. The paper also tries to establish a link between the notion of efficiency and the coefficients effect in the Oaxaca decomposition methodology. The results obtained are interpreted in light of the poor but efficient hypothesis.     

Bank Ownership and Efficiency in the Aftermath of Financial Crises: Evidence from Indonesia

This paper examines the relationship between types of ownership of banks and their efficiency in the aftermath of a financial crisis using Greene's “true” panel data stochastic frontier model, which takes into account unobserved heterogeneity among banks. The Indonesian banking sector is analyzed using financial data of 144 banks operating in Indonesia over the period of 2000Q4–2005Q2. In the aftermath of the 1997 Asian financial crisis, the cost efficiency of all banks improves over time on average. However, there is some evidence that, as these banks improve their efficiency, state‐owned banks are the least efficient banks while joint‐venture and foreign‐owned banks are the most efficient.
