Cost efficiency and the effect of mergers on the Taiwanese banking industry

This study addresses the cost efficiency, economies of scale and scope of the Taiwanese banking industry, specifically focusing on how bank mergers affect cost efficiency. Adopting stochastic frontier analysis, we employ a translog cost function for efficiency estimation. Composite error terms are used to account for managerial inefficiency and environmental effects. Empirical results suggest that economies of scale and scope exist at small and medium-sized banks. Meanwhile, government-owned or -controlled banks are the most cost efficient. Non-performing loans increase the inefficiency of the banking sector by just under 10 per cent. Further analysis reveals that bank merger activity is positively related to cost efficiency. Mergers can enhance cost efficiency, even though the number of bank employees does not decline. The banks involved in mergers are generally small and were established after the banking sector was deregulated.     

民营化、国有化与中国国有银行改革

国有银行自上世纪70年代中期以来出现了民营化的国际趋势,一些国家因此发生了银行危机.而此前全球曾有过国有化浪潮.虽然国有银行效率比民营银行低,但经验研究却表明,国有银行与银行危机之间没有或很少有因果关系;而且由于有政府信誉担保不易发生挤兑.中国国有银行改革过程实际上是政府逐步放弃控制权的过程,但切不可因效率而忽视金融稳定;简单地依靠所有权变更无法解决国有银行脆弱性问题;而且,与境外战略投资者合作时要谨防金融主权失控风险.     

The impact of mergers in banking : Evidence from a nationwide sample of federally chartered banks

Spurred by deregulation, cost, and risk factors, commercial bank mergers have accelerated sharply in recent years. Many banks appear to be positioning themselves for the advent of interstate banking through holding company or reciprocal branching arrangements. Yet, the performance effects of mergers among operating U.S. banks (as opposed to holding company acquisitions) have been examined both infrequently and inconclusively. This study focuses upon the characteristics and performance effects of national bank mergers occurring during the 1970–1980 period. Acquiring national banks were found to have lower operating efficiency and productivity than nonmerging banks and their profitability did not increase following the mergers, but credit availability, productivity, loan losses, deposit service charges, and interest-rate risk did rise. Frequency of merger activity did not significantly influence bank profitability or growth, but did augment stockholder risks and increase business and real-estate credit. In the aggregate, national bank mergers appeared to result neither in significant service benefits nor in significant service costs to the public.Spurred by deregulation of the industry, rising cost pressures, and increased operating risk, merger transactions among U.S. banks have soared in recent years. During the 1982–1986 period, for example, banking led all other industries in the number of consummated mergers and consistently was among the ten leading U.S. industries in the estimated market value of merger agreements. Moreover, the recent upsurge in reciprocal interstate banking agreements and proposals for fully legalized interstate banking hold out the prospect for a further acceleration in bank merger transactions in the years ahead. In view of the fact that legislation in more than 30 states now permits some form of interstate banking by merger or de novo entry and a June 1985 ruling of the U.S. Supreme Court has legitimized regional banking compacts, the public and private impact of bank mergers becomes of much greater importance as a research focus.Despite the magnitude of recent bank merger transactions and their implications for the public, the research literature in this area is surprisingly meager and often contradictory. This article is an attempt to focus more sharply on recent research findings, provide additional evidence concerning the effects of mergers on the financial performance of banks, and assess their impact on the public's interest in an adequate supply of financial services.     

行政处罚对银行风险承担的影响：仅罚机构还是兼罚责任人？

立足于我国监管部门大力整治银行业市场乱象的现状，文章系统梳理了不同类型行政处罚对银行风险承担的影响机制，并利用手工整理的2008-2018年银行行政处罚数据，对理论假说进行实证检验。经验结果显示，“仅机构处罚”不能显著降低银行风险承担水平，“双罚”可以有效抑制银行风险承担，并且这种抑制作用具有长期效应。异质性检验表明，“双罚”对大银行、国有银行和全国性银行风险的抑制作用更明显。机制检验发现,减少理财产品、同业业务等影子银行规模是“双罚”降低银行风险承担的重要渠道。研究还发现，随着责任人处罚严厉程度的上升，“双罚”对银行风险承担的抑制效果越好。政策启示在于，加大责任人问责力度，整治影子银行乱象，是监管部门防范银行风险的关键所在。     

审慎监管有效性的实证研究——基于银行效率和风险的视角

基于2007～2013年我国商业银行面板数据,检验审慎监管指标与银行效率和风险的关系,从银行发展的视角对审慎监管有效性进行实证分析.研究发现;较高的资本充足率在降低银行信贷风险的同时,也导致其成本效率和利润效率下降;拨备覆盖率的增加有利于降低银行信贷风险,但却显著地提高了银行成本效率;存贷比监管不仅不能降低银行信贷风险和经营风险,还显著地增加了银行成本效率和利润效率,流动性比率对银行风险和银行效率的影响均不显著.这些结论表明,不同审慎监管工具对银行风险和效率的影响存在差别,部分审慎监管工具在降低银行风险的同时,也降低了银行效率,审慎监管的目标在效率和风险之间存在一定的取舍.     

Bank risk-taking and competition in developing banking markets: Does efficiency level matter? Evidence from Africa

We contribute to the existing literature on the nonlinear nexus between competition and risk-taking by exploring how differences in efficiency levels affect the risk-taking of banks when competition increases. Based on a sample of 430 African banks, this paper reveals that, banks with high and low efficiency tend to take more risk than those with average efficiency level. This study further suggests that bank specific characteristics and macroeconomic dynamics, play an important role in the competition-risk-taking nexus within African banking industry. Besides, while the penetration of African Cross-border banks does not stimulate risk-taking in the hosts domestic markets, an improvement of banking regulation (Basel 2.5, 3 and further) is mandatory to mitigate their possible adverse effects on the competition-financial stability nexus.     

Technical Efficiency of the Ghanaian Banking Industry and the Effects of the Entry of Foreign Banks

The effects of the entry of foreign banks and changes in bank concentration on the technical efficiency of domestic banks in Ghana over the period 2000–2008 is analyzed. Technical efficiency scores were obtained by the Data Envelopment Analysis. Then, the Tobit regression was used to analyze the impact of hypothesized explanatory variables on bank efficiency. Foreign bank share of total industry assets was used to proxy the impact of foreign banks. The findings suggest that efficiency of domestic banks has been positively affected by the entry of foreign banks and reduction in concentration. Thus, the central bank's policy of liberalizing the banking sector appears to be well placed.     

Market structure,risk taking,and the efficiency of Chinese commercial banks

We investigate the impacts of market structure and bank risk taking on the efficiency of Chinese commercial banks, employing a two-stage semi-parametric data envelopment analysis model. Our empirical results show that the intense market competition compels Chinese commercial banks to develop advanced technical experience and skills, thus improving their technical efficiency. Besides, the technical efficiency is positive associated with the risk taking. Since more risk taking implies a credit expansion of Chinese commercial banks based on the soft risk constraint, the improvement of technical efficiency may accompany an accumulation of banking risks in the current financial system of China.     

Assessing the global productive efficiency of Chinese banks using the cross-efficiency interval and VIKOR

The banking industry plays an essential role in China's economic growth, and the assessment of bank efficiency has attracted increasing interest in the past two decades. Given that the data envelopment analysis cross-efficiency method can provide a more reliable reference set, a large number of studies targeting performance evaluation and its applications adopt this method. Few studies, however, address the issue of the non-uniqueness of weights in cross-efficiency evaluation. Whereas, this paper proposes a cross-efficiency interval considering all weighting schemes along with a VIKOR aggregate model to gauge the universal productive efficiency of 16 major Chinese commercial banks of China and rank them for the period of 2007–14. Specifically, we use the cross-efficiency interval to generate the global performance of each bank based on internal and external assessment while using VIKOR to compare the solution with the attitude index which ranks all of the banks. The results indicate that the cross-efficiency interval can provide more information than the traditional DEA model, that the banking system efficiency of China has been improved during the study period, especially for SOBs; that JSBs are more efficient compared with SOBs; and the efficiency gap narrowed during the study period.     

Foreign banking in developing countries; origin matters

Driven by globalization and increased financial integration, the last decade has seen many foreign banks entering developing countries. Although the majority of these banks are from high-income countries, recently banks from developing countries have followed suit. This paper looks at this phenomenon, by examining the differences and similarities between developing and high-income country foreign banks. Using a large dataset on banking sector FDI in developing countries, we find that 27% of all foreign banks in developing countries are owned by a bank from another developing country, while these banks hold 5%of the foreign assets. The importance of developing country foreign banks is much larger in low-income countries (both in number of banks and in terms of assets) and this type of foreign banking is strongly regionally concentrated. Although foreign bank entry by both developing country as well as high-income country banks seems to be driven by economic integration, common language and proximity, banks from developing countries are more likely to invest in small developing countries with weak institutions where high-income country banks are reluctant to go. This result seems to suggest that developing country banks have a competitive advantage dealing with countries with a weak institutional climate. Furthermore, our results indicate that developing country foreign banks have a higher interest margin and are less profitable than foreign banks from high-income countries.     

Banking across borders

The international linkages between banks play a crucial role in today's global economy. Existing models explain these links largely on the basis of portfolio theory, in which banks diversify lending. These models have found limited empirical support and do not speak to several relevant dimensions of the data. They do not explain heterogeneity in the degree to which banks operate through foreign affiliates, fund their activities abroad or matter for local lending in foreign countries. This paper proposes a complementary theory of banking across borders that is based on elements of international trade theory. In the model, banking across borders arises because countries differ in their relative factor endowments and in the efficiency of their banking sectors. Based on these differences, the pattern of foreign bank asset and liability holdings emerges endogenously. This parsimonious model provides a rationale for the observed heterogeneity in foreign bank activities and is consistent with key patterns in the data.     

Loyalty,naivety and powerlessness among Norwegian retail bank customers

The quantitative analysis presented in this paper builds on a qualitative focus group study of mobility among bank customers. The main finding from the focus group study was that mobile bank customers had a reflective – often critical ? relation to their banks, while the immobile bank customers had an unreflective – often trusting – relation to their banks. The study also resulted in a typology identifying different bank customer orientations. In the present paper, this typology has been operationalized and modified for further quantitative estimation and investigation. Nine different bank orientations are distinguished, and the results indicate that at least two of three bank customers do not regularly monitor their banking terms and conditions. In other words, it is reasonable to believe that the ordinary bank customer is not acting as expected according to the theory of well‐functioning market mechanisms. Resourceful consumers, with high incomes and education levels, tend to be more financially oriented than others. When people with meagre financial resources tend to end up in the more unfavourable banks, this is not solely a result of the banks’ own discrimination of the poor; it is also due to the fact that people with high incomes and education levels are more likely to monitor their banking conditions than people with low incomes, irrespective of whether or not they have bank loans. The quantitative material analysed was collected in February 2007 by computer‐assisted telephone interviews. One thousand randomly selected respondents answered the questions.     

Bank Performance and Credit Availability in the Bulgarian Banking Sector, 1997-2001

Abstract

The 1997 financial crisis wiped out 30% of the Bulgarian banking sector and created severe strains on corporations. With the establishment of the currency board in 1997 and the new Banking Law, which set the legal framework for proper bank supervision, major Bulgarian banks were rapidly privatized through sales to foreigners, now controlling around 80% of bank assets. Since 1997, the Bulgarian banking sector has recovered from the crisis by improving its profitability and efficiency and adopted a legal framework compatible with the European Union standards. Based on a regression analysis of bank balance sheets and income statements, this paper shows that low level of credit volume during 1997-1999 derived from banks' cautious stance towards credit making reflecting both the ongoing risks in the real sector, and the stringent new banking regulations. Large banks, however, benefited from scale economies in improving profitability in the same period.

Efficiency and total factor productivity change of Malaysian commercial banks

This paper analyses the efficiency of Malaysian commercial banks between 1996 and 2002 and finds that while the East Asian financial crisis caused a short-term increase in efficiency in 1998 primarily due to cost-cutting, increases in non-performing loans after the crisis caused a more sustained decline in bank efficiency. It is also found that mergers, fully Islamic banks, and conventional banks operating Islamic banking windows are all associated with lower efficiency. The paper estimates suggest mild decreasing returns to scale, and an average productivity change of 2.37% that is primarily attributable to technical change, which has nonetheless declined over time. Finally, while Islamic banks have been moderately successful in developing new products and technologies, the results suggest that the potential for Islamic banks to overcome their relative inefficiency is limited.     

Nationale Geldsch?pfung zersetzt den Euroraum

The Eurosystem has been operating in crisis mode for more than four years now. Massive quantitative and qualitative easing in its monetary policy stance are the visible marks of its response to the turbulence in the financial sector. This policy aims primarily at maintaining financial stability in the euro area by providing vast liquidity support to commercial banks that are operating in nationally segmented banking systems. The sovereign debt crises in some member countries further exacerbate the segmentation problem along country borders. As a side effect, cross-border capital flows are substituted by money market operations by the national central banks. The latter are engaging more and more often in substantial balance-of-payments financing, and financial risks are shifted from investors to European taxpayers via the Eurosystem. Symptomatically, this shows up in exploding TARGET2 positions in the national central banks’ balance sheets. The longer this process continues, the stronger the centrifugal forces become that ultimately might burst the single currency. A solution requires a euro area-wide regulatory approach for the financial sector. Next to a uniform scheme for banking regulation, supervision and resolution, we recommend the comprehensive introduction of contingent convertible bonds (CoCos) as a major refinancing source for the banking industry. As this proposal cannot be introduced overnight, national and European banking resolution funds are necessary in the short run. The latter do not rescue banks, but they kick in as soon as a bank’s equity is depleted in order to wind down failing banks in a systemically prudent way.     

Off-balance sheet activities and cost inefficiency in Taiwan's Banks

In this study, we adopt a stochastic cost frontier method to investigate the influence of off-balance sheet (OBS) activities on the cost efficiency of Taiwan's banks. We estimate and compare cost inefficiency with or without OBS outputs of 46 Taiwanese commercial banks during the period, 1998 through 2001. The conclusions of this empirical study are as follows. First, omitting off-balance sheet outputs in estimating the cost frontier function of banks results in an underestimation of bank efficiency by approximately 5 per cent. Second, large banks are associated with a higher cost efficiency and have an increased ability to develop OBS activities. This is consistent with Taiwan's regulatory policies, which focus on promoting efficiency in the banking industry of emerging markets. Banks with higher employee productivity are also more cost efficient. Finally, we observe evidence of economies of scale in both models with or without OBS specification in Taiwan's bank industry. Economies of scope between loans and OBS outputs are also observed.     

Determinants of Interest Rates on Time Deposits and Savings Accounts: Macro Factors,Bank Risk,and Account Features

Using a novel dataset from the Netherlands' banking sector, we examine how macroeconomic, bank‐specific, and account‐specific characteristics affect the interest rates of banking products. Our results show that interest rates have become more sensitive to bank risk since the onset of the global financial crisis. More generally, we show that time deposits reflect more closely the economic environment than bank interest rates on savings accounts do. Interest rates on deposit products vary not only across, but also within banks (i.e., across account of individual banks). We find that maturity‐increasing conditions (i.e., withdrawal fees for savings accounts and product maturity for time deposits) positively influence a product's interest rate.     

Retail bank selection in developed and developing countries: A cross‐national study of students' bank‐selection criteria

This exploratory research article is concerned with students' selection of retail banks in the United States and Ghana. It is a comparative cross‐national study aimed at revealing the factors determining retail bank selection among students in different environmental settings. The key objective is to establish if there are any significant differences and/or similarities in students' selection of retail banks in developed and developing economies. A similar data‐collection method was employed in the United States and Ghana to facilitate constructive comparison. The results identified four key factors—convenience, competence, recommendation by parents, and free banking and/or no bank charges—to be consistent across the two economies. The recommendation of the study is that in the context of an open and liberalized market environment, retail bank marketing strategies should be standardized irrespective of the national development stage. It concludes that retail bank managers particularly in developing countries should learn to provide consistent and good customer care. © 2009 Wiley Periodicals, Inc.     

Are Foreign Banks Better Performers Than Domestic Counterparts? Examining the Financialization Hypothesis in Mexico

This article analyzes the relationship between “financialization” and the performance of credit institutions in Mexico over the period 1999–2013. On average, foreign banks have higher cost-to-income ratio and return on assets than domestically owned banks. Non-interest income to gross revenue positively contributes to foreign bank profits, which highlights income other than conventional banking transactions. When considering references in the literature to non-interest income as a proxy for financialization, our results imply that domestic banks are more dependent on traditional lending, such as interest-earning assets, whereas foreign banks seem to engage in greater diversification to support profitability. Overall, the banking system reveals tendencies (“financialization”) that can possibly work against credit facilitation in Mexico.
