Evaluating business performance of wealth management banks

This study applies the balanced scorecard method to build a performance evaluation framework for wealth management (WM) banks. Next, the study builds a framework for dealing with sub-criteria using the Delphi method and finally, the article evaluates the business performance of WM banks in Taiwan by applying the analytical hierarchy process (AHP) and grey relational analysis (GRA). Importantly, the proposed model can benefit the banking sector in assessing the business performance of WM banks, making it highly applicable for bank managers and financial sector analysts.     

The Greek banking system: Reanalysis of performance

Zopounidis et al. used an ordinal regression analysis to assess an additive utility model and to obtain final ranking of a representative sample of commercial Greek banks [C. Zopounidis, D.K. Despotis, E. Stavropoulou, Multiattribute evaluation of Greek banking performance, Applied Stochastic Models and Data Analysis 11 (1995) 97–107]. In this paper, we reanalyze their data by means of a new multivariate analysis method called Co-plot, a two-dimensional graphic display technique designed to analyze observations (e.g., 16 banks) and attributes (e.g., 7 attributes) simultaneously. The method produces three results: (1) similarity among the banks by the composite of all attributes involved (five clusters are obtained), (2) the structure of correlations among the attributes (three clusters are obtained), and (3) the mutual relationships between the banks and the attributes. The banks are mapped into a partial order according to their (increased) performance to obtain their rating. The final ranking obtained by the Co-plot method differed from that obtained by Zopounidis et al.     

Multicriteria classification models for the identification of targets and acquirers in the Asian banking sector

The purpose of the present study is the development of classification models for the identification of acquirers and targets in the Asian banking sector. We use a sample of 52 targets and 47 acquirers that were involved in acquisitions in 9 Asian banking markets during 1998–2004 and match them by country and time with an equal number of non-involved banks. The models are developed and validated through a tenfold cross-validation approach using two multicriteria decision aid techniques. For comparison purposes we also develop models through discriminant analysis. The results indicate that the multicriteria decision aid models are more efficient that the ones developed through discriminant analysis. Furthermore, in all the cases the models are more efficient in distinguishing between acquirers and non-involved banks than between targets and non-involved banks. Finally, the models with a binary outcome achieve higher accuracies than the ones which simultaneously distinguish between acquirers, targets and non-involved banks.     

商业银行财务绩效偏序集评价研究

为了提高商业银行财务绩效水平,满足利益相关者信息需求,从收益和风险以及发展的角度构建"盈利性"、"安全性"、"流动性"和"社会性"四个维度的商业银行财务绩效评价指标体系,采用偏序集评价方法对15家样本商业银行2017年财务绩效进行评价。财务绩效排名和HASSE图的结果表明:处于较高层级的样本商业银行财务绩效较好,其盈利性、安全性、流动性较优,并具备较强的发展能力;处于较低层级的样本商业银行财务绩效较差,其盈利性、安全性、流动性较弱,发展能力较弱;重要性程度靠前的"盈利性"和"安全性"评价维度,不是导致商业银行绩效排名和分层的主要影响因素,商业银行要提升财务绩效,应该更加重视"流动性"和"社会性"维度。同时,采用偏序集评价方法,克服了评价指标精确赋权问题,获得的HASSE图直观展示样本商业银行财务绩效排名稳定性和整体市场竞争格局,具备其他评价方法无法比拟的优势。     

Foreign versus domestic banks’ performance in the UK: a multicriteria approach

Although the banking sector in the UK is one of the most open and it is characterized by an increasing foreign bank presence, it remains relatively under-researched compared to studies for other countries. The objective of this paper is to investigate the performance of the UK banking sector focusing on the performance of the domestic banks as opposed to the performance of the foreign banks in order to test the hypothesis of higher performance of the domestic banks in a developed market. For this purpose, the UTADIS multicriteria methodology is employed to compare domestic and foreign banks performance over multiple criteria, such as profitability, liquidity, risk and efficiency, using a data sample covering 26 domestic and 32 foreign banks operating in the UK over the period 1998 to 2001. The results of the study, support the home advantage hypothesis, suggesting that the higher performance of domestic banks compared to foreign banks is also the case in the UK. The most important distinguishing performance factors between the two groups of banks are interest revenue to total earning assets, and profit before taxes to loans plus securities, which are higher for the domestic banks.AMS classification: 91B28     

Unveiling endogeneity between competition and efficiency in Chinese banks: a two-stage network DEA and regression analysis

Although there is a growing number of research articles investigating the performance in the banking industry, research on Chinese banking efficiency is rather focused on discussing rankings to the detriment of unveiling its productive structure in light of banking competition. This issue is of utmost importance considering the relevant transformations in the Chinese economy over the last decades. This is a development of a two-stage network production process (production and intermediation approaches in banking, respectively) to evaluate the efficiency level of Chinese commercial banks. In the second stage regression analysis, an integrated Multi-Layer Perceptron/Hidden Markov model is used for the first time to unveil endogeneity among banking competition, contextual variables, and efficiency levels of the production and intermediation approaches in banking. The competitive condition in the Chinese banking industry is measured by Panar–Rosse H-statistic and Lerner index under the Ordinary Least Square regression. Findings reveal that productive efficiency appears to be positively impacted by competition and market power. Second, credit risk analysis in older local banks, which focus the province level, would possibly be the fact that jeopardizes the productive efficiency levels of the entire banking industry in China. Thirdly, it is found that a perfect banking competition structure at the province level and a reduced market power of local banks are drivers of a sound banking system. Finally, our findings suggest that concentration of credit in a few banks leads to an increase in bank productivity.

     

On the construction of mutual fund portfolios: A multicriteria methodology and an application to the Greek market of equity mutual funds

The evaluation of the performance of mutual funds (MFs) has been a very interesting research topic not only for researchers, but also for managers of financial, banking and investment institutions. In this paper, an integrated methodological framework for the evaluation of MF performance is proposed. The proposed methodology is based on the combination of discrete and continuous multicriteria decision aid (MCDA) methods for MFs selection and composition. In the first stage of the analysis the UTADIS MCDA method is employed in order to develop mutual fund's performance models supporting the selection of a small set of MFs, which will compose the final portfolios. In the second stage, a goal programming model is employed to determine the proportion of the selected MFs in the final portfolios. The methodology is applied on data of Greek MFs over the period 1999–2001 with encouraging results.     

Assessing financial distress where bankruptcy is not an option: An alternative approach for local municipalities

The goal of this paper is to build an operational model for evaluating the financial viability of local municipalities in Greece. For this purpose, a multicriteria methodology is implemented combining a simulation analysis approach (stochastic multicriteria acceptability analysis) with a disaggregation technique. In particular, an evaluation model is developed on the basis of accrual financial data from 360 Greek municipalities for 2007. A set of customized to the local government context financial ratios is defined that rate municipalities and distinguish those with good financial condition from those experiencing financial problems. The model’s results are analyzed on the 2007 data as well as on a subsample of 100 local governments in 2009. The model succeeded in correctly classifying distressed municipalities according to a benchmark set by the central government in 2010. Such a model and methodology could be particularly useful for performance assessment in the context of several European Union countries that have a similar local government framework to the Greek one and apply accrual accounting techniques.     

中国银行业市场竞争结构测度:基于Bresnahan范式研究

自从金融体系改革在中国开展以来,我国银行业的市场结构和竞争程度发生了巨大的变化。本文基于一般市场均衡理论框架对Bresnahan范式进行修正,采用1995-2004年间14家商业银行的数据建立panel data模型,对我国银行业的竞争结构进行测度。结果表明:1995-2004年期间,我国银行业处于较为明显的垄断竞争市场结构,比较1995-1998年和1999-2004年分析结果可以看出,我国银行业的竞争趋势渐强;4家国有商业银行之间具备高竞争程度的垄断竞争市场结构特征,10家股份制商业银行之间的竞争程度明显低于国有商业银行之间的竞争程度。     

Resource,service quality and performance triad: a framework for measuring efficiency of banking services

In this paper, we present the development of a theoretical framework for measuring the efficiency of banking services taking into account physical and human resources, service quality and performance. Expenditures on quality improvement efforts and the impact of service quality on financial outcomes have long intrigued researchers. Banks have traditionally focused on how to transform their physical resources to generate financial performance, and they inadvertently ignored the mediating intangible factor of service quality. A theoretical framework on the optimization triad of resource, service quality and performance is proposed here, thereby linking the marketing variables to the financial metrics. A measure for the return on quality is developed as the ratio of the potential improvements in financial performance by enhancement of service quality to the observed performance figures. Empirical results obtained from a study of 27 Indian public sector banks and their customers allow us to measure the impact of service quality on financial performance, optimal level of service quality that can be generated using existing resources and the opportunity cost for sub-optimal service delivery. Banks delivering better service are shown to have better transformation of resource to performance using superior service delivery as the medium. Our results confirm the linkage between resource, service quality and performance for services.     

A study on the persistence of Farrell’s efficiency measure under a dynamic framework

This article introduces a sequence of four systematic methods to examine the extent to which the economic efficiency of Taiwan’s commercial banks persists and to uncover the potential dynamic link between bank performance and various financial indicators. Quasi-fixed inputs are explicitly incorporated in the DEA model to account for possible adjustment costs, regulation, or indivisibilities. Among the four methods, the dynamic panel data model and the Markov model appear to be exploited for the first time in the area of the DEA approach. Evidence is found that bank efficiency exhibits moderate persistence over the sample period, implying that the given sample banks fail to adjust their production techniques in a timely manner. Regulatory authorities and bank managers are suggested to be aware of the level of undesirable non-performing loans due to their close relationship with bank performance.     

网络结构、资本缓冲与银行系统性风险传染效应——来自2007~2017年中国14个上市商业银行数据

银行体系稳健运行对国民经济健康发展具有重要意义。选取2007~2017年中国14个上市商业银行数据,利用债务矩阵构建银行网络,运用无残差完全分解模型将其分解为网络结构和资本缓冲两个因素,对我国银行系统性风险传染效应研究。结果表明:网络结构与银行系统性风险存在复杂的关联性,而资本缓冲与银行系统性风险有显著负相关关系;在金融危机期间,网络结构是诱导银行系统性风险波动的决定性因素,资本缓冲对降低银行系统性风险有重要作用。此外国有商业银行与其他银行债务关系更为紧密,对系统性金融风险贡献较大,中国银行处于网络结构中重要位置,中国工商银行和中国建设银行处于次重要位置。该结果为资本监管政策和宏观审慎政策有效实施提供了理论依据。     

An enhanced DEA model for decomposition of technical efficiency in banking

Past studies about the application of data envelopment analysis (DEA) to banking performance often follow the concept of technical efficiency (TE) and/or the productivity defined by the TE. In this paper, we propose an enhanced DEA model, based on a modification of the directional distance function by simultaneously but disproportionately seeking the maximum expansion of each desirable output and contraction of each undesirable output for efficiency measurement, which allows us to decompose the TE into operating efficiency (OPE) and risk management efficiency (RME). The OPE characterizes the ability of a bank to expand the room for profits through its regular business activities, while the RME describes a bank’s ability in risk management activities for sustaining operations. To illustrate the usefulness of the proposed model, a case study of Taiwan’s domestic commercial banks is presented. The major findings are that operating inefficiency is the main source of technical inefficiency, although banks with a higher OPE generally also have a higher RME. Banks subordinate to financial holding companies are more efficient in both OPE and RME than stand-alone banks.     

考虑服务水平的商业银行综合效率评价研究

商业银行是我国银行体系的主体,提高银行的经营效率和服务水平是当前金融改革的重点。已有的研究较多关注于银行的收益,对银行的非期望产出如呆坏账及服务水平等关注较少。本文运用多个处理非期望产出的DEA模型,对2008年中国商业银行的效率进行了评价分析。文章在改进熵DEA方法的基础上,利用指标体系对商业银行的综合效率进行了测度并对比了处于多模型条件下模型的区分度问题。研究结果显示,呆坏账、服务水平(等待时间)等非期望产出对商业银行的效率意义重大;股份制商业银行的效率普遍高于国有商业银行,因此国有商业银行的股份制改造是一个积极的方向。最后,根据实证分析的结果提出的效率改进建议对商业银行的自身发展和管理当局的改革规划都具有重要的指导意义。     

Computing nonperforming loan prices in banking efficiency analysis

Within the framework of banking efficiency analysis, we propose a methodology for computing unobservable shadow prices for nonperforming loans (NPL). Our approach is to include NPL as an undesirable output variable in a distance function stochastic frontier analysis. We conduct a panel study of US and European banks during the most recent financial crisis by adopting a semi-nonparametric Fourier specification, which ensures convergence to the true values of both the estimated function and the related efficiency. Computing NPL prices has several advantages, such as identifying approaching crises, quantifying the responsibilities of governments and banks for credit risk and determining appropriate regulatory interventions.

     

Assessing performance factors in the UK banking sector: A multicriteria methodology

Further consolidation takes place not only among UK banks but also across borders, since some banks see size as a key factor in remaining competitive in international markets. Therefore, it is interesting to investigate the effectiveness and performance of UK banks. Based on their assets, banks are distinguished into small and large ones and a classification of UK banks in a multivariate environment for the period 1998–2002 takes place. The PAIRCLAS multicriteria methodology is employed to investigate the performance of UK small and large banks over multiple criteria, such as asset quality, capital adequacy, liquidity and efficiency/profitability. A comparison with discriminant analysis (DA) and logistic regression (LR) facilitates the investigation of the relative performance of PAIRCLAS against them. The results of the study determine the key factors that specify the classification of a bank as small or large and provide us with the responsible banking decision makers for future readjustments.     

中国银行系统的宏观审慎监管研究

全球金融危机爆发后,对银行系统实行审慎监管已成为国内外学者及相关监管机构的共识。但目前银行系统的监管研究多为微观审慎监管,宏观审慎监管研究缺乏,尤其是对中国银行网络系统进行动态建模并进行宏观审慎监管的定量研究未见。本文首先利用中国2008至2015年16家上市银行的实际数据构建动态的中国银行网络系统模型,然后使用Component VaR、Incremental VaR、Shapley value EL以及ΔCoVaR四种风险分配机制研究中国银行网络系统的宏观审慎监管方法。研究表明:对中国银行网络系统进行宏观审慎监管能够有效提升其稳定性,并且四种机制相比之下,ΔCoVaR的监管效果最为显著,而Incremental VaR则相对较差。此外,通过宏观审慎资本与银行指标之间的相关性分析,发现Incremental VaR、Shapley value EL以及Component VaR机制下的宏观审慎资本与银行的总资产具有一定的相关性,此时宏观审慎资本可以根据银行的总资产来设置;而ΔCoVaR机制下则不相关,因此宏观审慎资本可以依据各银行的系统性风险贡献大小来设置。     

Large exposure estimation through automatic business group identification

Large exposure rules are considered critical for financial institutions, as they directly restrict the lending activity of banks to clients. However, empirical evidence suggests that those rules are difficult both for regulators to enforce and for financial institutions to implement. We present a data-driven analytical model that automatically and algorithmically creates groups of related parties based on ownership information, financial dependencies, business associations, and family ties. We develop a methodology based on linear algebra and networks to group clients, highlight missing critical information, and identify unreported business partners. The approach can be used both prospectively by banking institutions analyzing credit risk and by regulators. We include a case study, applying the methodology retrospectively to highlight large exposure violations and systemic risk leading up to the 2008 banking crises in Iceland.     

Prediction of Greek company takeovers via multivariate analysis of financial ratios

This case study evaluates the financial features of Greek firms that were taken over during the period 1983–1990. A sample of acquired firms and a sample of equivalent non-acquired firms are considered with the objective of distinguishing between them, based upon their differences in sixteen financial characteristics 1–3 years prior to each takeover. Linear and quadratic discriminant analysis and logit models are developed with factor analysis input. Prediction results are mixed, mainly due to the similar financial ratio profiles between acquired and non-acquired firms. Most models classify correctly a significant proportion of acquired or non-acquired firms, but not both (with one exception). The only model that provides significantly correct predictions for both acquired and non-acquired firms in either the calibration or holdout sample is a linear discriminant function with six financial ratios (two from each of the three years prior to takeover). The reasons for these modelling difficulties are discussed.     

Greek football clubs’ efficiency before and after Euro 2004 Victory: a bootstrap approach

This paper examines the technical efficiency of Greek football clubs, taking into account the period before the Euro 2004 victory and the period thereafter. The first stage of analysis is based on a bootstrapped data envelopment analysis approach so as to determine Greek clubs’ efficiency scores during these two distinct time periods. The second stage of analysis investigates possible factors that may have affected the efficiency scores during the examined periods. Our findings reveal that Greek football clubs exhibit surprisingly lower efficiency scores after Euro victory. In effect and explained in the context of the Resource Based Theory, there appears to be no classification of types of football clubs into various divisions, viz. laggards, followers and champions. Finally, it is also found that clubs’ financial health appears to be a crucial factor for their performance in both periods.
