Financial deregulation and efficiency: An empirical analysis of Indian banks during the post reform period

The paper investigates the performance of Indian commercial banking sector during the post reform period 1992-2002. Several efficiency estimates of individual banks are evaluated using nonparametric Data Envelopment Analysis (DEA). Three different approaches viz., intermediation approach, value-added approach and operating approach have been employed to differentiate how efficiency scores vary with changes in inputs and outputs. The analysis links the variation in calculated efficiencies to a set of variables, i.e., bank size, ownership, capital adequacy ratio, non-performing loans and management quality. The findings suggest that medium-sized public sector banks performed reasonably well and are more likely to operate at higher levels of technical efficiency. A close relationship is observed between efficiency and soundness as determined by bank's capital adequacy ratio. The empirical results also show that technically more efficient banks are those that have, on an average, less non-performing loans. A multivariate analysis based on the Tobit model reinforces these findings.     

The impacts of risk-taking behaviour and competition on technical efficiency: Evidence from the Chinese banking industry

This paper tests the impact of risk and competition on efficiency in the Chinese banking industry over the period 2003–2013. Comprehensive types of risk-taking behaviour are considered including credit risk, liquidity risk, capital risk, and insolvency risk. Competition is measured by the Lerner index. The results are cross-checked using an alternative econometric technique as well as an alternative competition indicator. The findings show that the technical and pure technical efficiencies of Chinese commercial banks are significantly and negatively affected by liquidity risk. They further show that greater competition precedes declines in technical and pure technical efficiencies of Chinese commercial banks. The results suggest that Chinese bank efficiency is significantly affected by bank diversification, banking sector development, stock market development, inflation and GDP growth rate. The findings also indicate that, compared to state-owned commercial banks, joint-stock commercial banks and city commercial banks have lower technical and pure technical efficiencies.     

中印国有商业银行经营效率比较研究

本文运用DEA方法,采用中国与印度共32家国有商业银行(其中中国4家,印度28家)2004财年的经营数据,分析了其技术效率、纯粹技术效率和规模效率,并将中国与印度的国有商业银行分成两组分别对三种效率做了对比检验。结论为两国国有商业银行技术效率值较高,但72%的银行处于规模不经济阶段,取得规模经济是两国大部分国有商业银行改革要面临的选择。印度国有商业银行各项效率稍微领先中国国有商业银行,但在统计上却均无显著性。虽然印度总量资产远小于中国,金融发展历史久于中国,但从整体上来说,作者认为并不像有些文献中提到的印度银行体系效率要远高于中国。     

The impact of regulatory reforms on cost structure,ownership and competition in Indian banking

This paper evaluates the impact of financial sector reforms on the cost structure characteristics and on the ownership–cost efficiency relationship in Indian banking. It also examines the impact of reforms on the dynamics of competition in the lending market. We find evidence that deregulation improves banks performance and fosters competition in the lending market. Results suggest technological progress, once Indian commercial banks have adjusted to the new regulatory environment. This, however, does not translate in efficiency gains. There is also evidence of an ownership effect on the level and pattern of efficiency change. Finally, competition keeps building pace even in the re-regulation period and technological improvements are not hampered by the tightening of prudential norms.     

Differential impact of Korean banking system reforms on bank productivity

We study the impact of banking system reforms during a crisis following a period of undisciplined lending. Regulatory changes aimed at strengthening the banks’ capital structure and risk management practices do not have a uniform impact on bank productivity, but rather favor financially sound or strategically privileged banks. We present evidence documenting the differential impact of regulatory reforms on Korean commercial bank productivity over the period 1995–2005. Average technical efficiency of banks decreased during the financial crisis of 1997–1998. It improved following the subsequent bank restructuring and continued to improve through 2005. The capital adequacy ratio is positively associated with banks’ technical efficiency. The non-performing loans ratio is negatively associated with technical efficiency. Both relationships are accentuated during the crisis but attenuated after the reforms.     

Indian bank efficiency and productivity changes with undesirable outputs: A disaggregated approach

The objective of this study is to examine technical efficiency and productivity growth in the Indian banking sector over the period from 2004 to 2011. We apply an innovative methodological approach introduced by Chen et al. (2011) and Barros et al. (2012), who use a weighted Russell directional distance model to measure technical inefficiency. We further modify and extend that model to measure TFP change with NPLs. We find that the inefficiency levels are significantly different among the three ownership structure of banks in India. Foreign banks have strong market position in India and they pull the production frontier in a more efficient direction. SPBs and domestic private banks show considerably higher inefficiency. We conclude that the restructuring policy applied in the late 1990s and early 2000s by the Indian government has not had a long-lasting effect.     

我国商业银行的效率现状及生产率变动分析

本文运用数据包络分析方法和Malmquist指数对我国28家三类商业银行2000～2004年的技术效率、纯技术效率和规模效率以及全要素生产率变动进行了测算。结果发现,三类商业性银行的效率存在差异:国有商业银行的规模效率最低,并且呈规模报酬递减;股份制商业银行效率略高于国有商业银行;城市商业银行效率由相对最低转为相对最高。总体上看,银行业全要素生产率呈上升趋势,技术效率呈下降趋势,规模效率无明显变化。本文的主要结论是:规模是影响国有商业银行和股份制商业银行效率差异的主要因素,银行全要素生产率的变动受信息技术发展的推动以及宏观环境的影响。     

基于DEA-BCC模型的城商行技术效率实证分析（2008-2012）

运用投入导向型的DEA-BCC 模型,对东部沿海10省市36家样本城商行2008-2012年的技术效率进行实证研究。研究表明,近五年来样本城商行总体技术效率保持平稳,并呈较为平坦的“V型”变化趋势,样本城商行的技术效率并没有在规模持续扩张的背景下得到持续有效提升。进一步对技术效率的分解项目进行分析发现,纯技术效率是制约样本城商行总体技术效率提升的主导因素,表明,样本城商行的内部管理能力亟待提升。此外,无论是总技术效率、纯技术效率还是规模效率,都与样本城商行的规模具有显著的相关性,总体而言,大型城商行的技术效率及纯技术效率要优于中小型城商行,但是,中型城商行在规模效率方面略胜一筹,样本城商行存在较为明显的“倒V型”成本曲线。     

Regional economic development,strategic investors,and efficiency of Chinese city commercial banks

We investigate the effect of strategic investors on bank efficiency in the context of regional economic development. The data on Chinese city commercial banks operating regionally are well-suited for the study. Our findings suggest that strategic investors significantly increase efficiency in Chinese city commercial banks, while the effect of strategic investors on the efficiency of Chinese city commercial banks is negatively correlated to the level of regional economic development. The negative correlation of the effect of strategic investors on Chinese city commercial banks’ efficiency with regional economic development may be explained by the mix of local official promotion system and city commercial banks’ governance structure.     

Schumpeterian competition and efficiency among commercial banks

In this paper, we aim to fill the gap in the banking literature by quantifying the impact that the Schumpeterian competition mode – i.e. competition through the launch of new products (or new varieties of products) – has on the cost and profit efficiency of a sample of commercial banks based in the United Kingdom. We estimate both a cost and an alternative profit frontier on an unbalanced panel of UK commercial banks over the period 2001–2012. The intensity of competition through product innovation is proxied by the trademark intensity (i.e. the ratio between the number of trademarks registered in a given year by all the commercial banks – net of the trademarks registered by the bank under observation – and the employment in the sector) in the commercial banking sector. Our results show that the (lagged) trademark intensity in the commercial banking sector does affect negatively the mean cost and profit efficiency in the sector but there is evidence that as trademark intensity increases in the sector, commercial banks react by improving their cost and profit efficiency.     

The contribution of product mix versus efficiency and technical change in US banking

Similar to a Du Pont analysis, this paper divides the changes in returns on assets of US commercial banks for the period from 2000 to 2005 into conventional measures of bank performance. The contribution of product mix is significant and offsets losses from technical change and operating efficiency. Banks respond to changes in the business environment by switching towards more lucrative traditional and nontraditional products. Large banks are found to benefit more than community banks from the switch to an optimal output portfolio mix including new products spawned by recent financial innovations and deregulation.     

Bank ownership,privatization, and performance: Evidence from a transition country

This paper combines the static effect of ownership and the dynamic effect of privatization on bank performance in China over 1995–2010, reporting a significantly higher performance by private intermediaries – joint stock commercial banks and city commercial banks – relative to state-owned commercial banks. However, publicly traded banks, subject to multiple monitoring and vetting in capital markets, perform better regardless of ownership status. The privatization of banks has improved performance with respect to revenue inflow and efficiency gains in the short- or long-run (initial public offerings). The positive long-run effect is more relevant and significant for banking institutions with minority foreign ownership. Moreover, this paper innovatively estimates interest income efficiency and non-interest income efficiency at the same time. The results suggest that Chinese banks are much more efficient in generating interest income than raising non-interest revenue, although the latter aspect has improved significantly during the sample period.     

基于SFA的鲁浙苏城商行技术效率对比及影响因素研究

文章采用随机前沿方法（SFA）估计了江苏、山东、浙江三地19家城市商业银行2007年-2012年的技术效率，在对比分析的同时研究影响其技术效率差异的非效率因素。实证结果表明，三地城商行六年来技术效率逐年提升，且浙江、山东五家城商行六年平均技术效率值位居前列，并表现出较为稳定的技术效率状态；法人治理结构是影响样本城商行技术效率差异的重要因素，适度分散化的股权结构及战略投资者持股与样本城商行的技术效率呈显著正相关。     

Technical Efficiency Measurement Incorporating Risk Preferences: An Empirical Analysis of Chinese Commercial Banks

By adjusting direction vectors, we are able to measure technical efficiency incorporating risk preference of individual banks using non-parametric and parametric approaches. Furthermore, we explore categories of commercial banks by comparing their risk preferences to the risk preference that optimizes technical efficiency. Three results emerged. First, technical efficiency scores of joint stock and city commercial banks surpassed those of state-owned commercial banks under the optimal risk preference, and technical efficiency generally improved over time. Second, the preference for risk balance was optimal for achieving technical efficiency. Third, a larger proportion of state-owned and joint stock commercial banks fall into the preference for risk neutral category than city commercial banks.     

基于面板数据的中国商业银行效率实证分析

针对以往参数方法存在权重确定困难的问题,本文提出了一种基于面板数据的银行效率评价的非参数方法（BEE）,同时构造了相应的数学模型（M-BEE）。然后,应用（M-BEE）模型对中国四家国有银行、八家股份制商业银行2001-2008年的经济效率状况进行了实证分析,结果表明,八年间中国12家商业银行的综合效率呈现逐年递增趋势,纯技术效率呈现先下降后上升的U型特征,规模效率缓慢上升,变化不显著;2006-2007年我国12家商业银行的综合效率和纯技术效率整体上都有大幅提升;八家股份制银行的综合效率和纯技术效率均明显高于四大国有银行。     

国内商业银行个人金融业务X效率比较——基于DEA理论

以国内10家商业银行作为样本,以银行总资产、人力资本为投入项,个人贷款利息收入、手续费收入为产出项,参照2009—2011年10家样本银行的经营数据,采用前沿的非参数分析方法——数据包络分析(DEA)对样本银行个人金融业务X效率进行比较分析。结果显示:在参考期间内国内商业银行个人金融业务规模效率、配置效率与纯技术效率接近生产可能性边界,但仍存在着X低效率与技术低效率的问题,且国有商业银行与股份制商业银行的发展水平存在一定差距。     

Ownership and technical efficiency of microfinance institutions: Empirical evidence from Latin America

By using stochastic frontier analysis, this article examines the technical efficiency of different types of microfinance institutions in Latin America. In particular, it tests whether differences in technical efficiency, both intra- and interfirm, can be explained by differences in ownership. With a focus on non-governmental organizations, cooperatives and credit unions, non-bank financial intermediaries, and banks, the data set contains 1681 observations from a panel of 315 institutions operating in 18 Latin American countries. The results show that non-governmental organizations and cooperatives have much lower interfirm and intrafirm technical efficiencies than non-bank financial intermediaries and banks, which indicates the importance of ownership type for technical efficiency.     

中国商业银行效率分析：基于外资参股比例的视角

本文首先选取16家上市银行2008-2013年的财务数据作为样本,运用DEA-Malmquist方法,得出了我国商业银行五个主要的效率指标：技术效率、技术水平、纯技术效率、规模效率与全要素生产效率的变化。随后按照外资参股比例的高低分组,运用Tobit回归模型,研究宏观经济环境、公司治理等因素对商业银行以上五个效率指标的影响。研究结果表明：对外资参股比例较高的商业银行而言,较窄存贷差的宏观环境能凸显其技术优势;中等外资参股水平的银行需增加人力投入以获取效率提升;对于低外资参股比例银行,应扩大所有者权益,找到资金投入的合理规模。     

Productivity and efficiency at large and community banks in the US: A Bayesian true random effects stochastic distance frontier analysis

This paper compares the productivity and efficiency of large banks and community banks in the United States over the period 1997–2006. This comparison is performed by estimating a true random effects stochastic distance frontier model—a model that is capable of disentangling unobserved heterogeneity from inefficiency—within a Bayesian framework. We find that failure to consider unobserved heterogeneity results in a misleading ranking of banks and mismeasured technical efficiency, productivity growth, and returns to scale. Our results show that, compared with community banks, large banks have experienced much higher productivity growth and higher levels of returns to scale. Our estimates of total factor productivity growth show a clear downward trend for both large and community banks, and our decomposition of the output-distance-function-based Divisia productivity index indicates that technical change is the driving force behind this trend.     

First Financial Restructuring and operating efficiency: Evidence from Taiwanese commercial banks

This paper investigates the effect of the “First Financial Restructuring” (FFR) on the operating efficiency of commercial banks in Taiwan. Applying data envelopment analysis (DEA) to operations data for 40 commercial banks over the 6-year period 2000–2005, we find that while the banks have lower operating efficiency on average during the reform period (2002–2003) compared to the pre-reform period (2000–2001), improved operating efficiency is reflected in the post-reform period (2004–2005). Our results remain unchanged even after controlling for the non-performing loan ratio, capital adequacy ratio, bank ownership, size, and GDP growth rate. These results suggest that the improved efficiency in the post-reform period is possibly due to enhanced banking and risk management practices and benefits obtained from compliance with the FFR.
