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.     

A new method to decompose profit efficiency: an application to US commercial banks

We propose a new method to estimate profit efficiency which makes explicit how revenue and cost efficiencies contribute to overall profit efficiency. Using data from US commercial banks from 2001 to 2010, we find that losses due to profit inefficiency represent about 3.5% of banks’ equity of which 1% is due to revenue inefficiency and 2.4% to cost inefficiency. Revenue efficiency changes affect more overall profit efficiency than equivalent cost efficiency changes. In contrast to previous studies, but in line with economic intuition, we find that while revenue and cost efficiencies tend to be negatively correlated, both correlate positively with profit efficiency.     

Keiretsu and risk: An examination of the risk exposure of keiretsu banks in Japan

We compare risk positions adopted by keiretsu and non-keiretsu banks in Japan and examine how the risk positions of Japanese banks changed following the conclusion in 1997 of an escalating series of banking crises in Japan and East-Asia. The results indicate that keiretsu banks take less risk than non-keiretsu banks, and that Japanese banks in general adopted lower risk profiles after 1997. Japanese bank risk is positively associated with the ratio of non-performing loans to capital, interest rates, and private investment in residential construction, and negatively with the ratio of administrative expenses to average assets and the money supply

A model for risk classification of banks

This paper deals with designing a bank risk classification scheme based on readily available performance data. This risk rating is referred to as ‘Risk rating’. Due to non-availability of data on CAMEL rating (C rating), R risk rating has potential for studying risk-based premiums insurance policy and for determining optimal frequencies for variable frequency on-site examination policy. A composite non-performance measure is developed to estimate probability of failure of a bank based on performance data available in bank call reports by fitting a Logit curve and estimating its parameters using maximum likelihood method. Division of banks into healthy and watchful types is based on critical dividing value of probability of failure.

本文运用2003-2013年间我国53家商业银行的面板数据,通过建立多元化风险模型,对商业银行收入结构多元化、经营绩效以及风险的关系进行了系统分析。得出结论：规模较大的银行在专业型多元化经营业务成熟的基础上,转而发展综合型多元化经营业务,有利于银行绩效提升,但必须注重对风险的把控;而规模较小的商业银行因受地域、规模等因素的限制并不适合开展综合型多元化经营业务,应在主营业务发展充分的基础上,以发展专业型多元化经营业务为主。最后,根据实证结果提出相关的对策建议。     

Form of ownership and risk taking in banking: Some evidence from Massachusetts savings banks

In recent years there has been interest in the impact of the form of ownership on the behavior of financial institutions. In the 1980’s, there was a substantial movement away from mutual ownership to stock ownership in the thrift industry. The effect of this conversion process on risk taking and efficiency has been a matter of concern. The purpose of this paper is to examine the experience of savings banks in Massachusetts. A panel of 115 savings banks is analyzed for the years 1985 through 1993, a period that includes both rapid growth and a subsequent severe cyclical decline in property values. The credit quality of loan portfolios is related to the size of the portfolio, the structure of the portfolio, and the ownership status of the bank. Several models are estimated. In all cases, it was found that the cyclical decline in property values resulted in a decline in the credit quality of loan portfolios with a substantially greater impact on those savings banks that converted from mutual to stock status.     

Exploring the sources of financial performance in Chinese banks: A comparative analysis of different types of banks

Since significantly organizational difference in Chinese banks, this study makes an attempt to investigate whether there exist some differences of the financial performance and its decomposed components for Chinese banks. We employ the decomposition of profit change model introduced by Grifell-Tatje and Lovell (2015, P215) and normalized price definition of Balk (2018) to develop a normalized profit change decomposition model which can well deal with the firms’ scale difference. This model also decomposes the normalized profit into the technical efficiency effect, technical effect, size effect, price and quantity margin effect, and price recovery effect. For the empirical evidence, we find that although there is an increase of profit gains, the profit growth rate decline by year. Furthermore, the productivity is not the main factor to expand profits, quantity margin effect also makes peer contributions. Finally, the productivity effect and its decomposed components present different functions in different kinds of Chinese banks.     

Credit risk of subsidiaries of foreign banks in CEE countries: Impacts of the parent bank and home country economic environment

In this study, using dynamic panel data, we investigated the influences of the home country economic environment and parent bank condition on the credit risk of foreign banks in Central and Eastern European (CEE) countries. We concentrated on the international transmission of credit risk through the internal capital market of multinational banks. Our theoretical assumptions follow studies that document how the parent bank condition and home country macroeconomic environment affect lending in subsidiaries in CEE countries. However, our results go one step further. We provide evidence that these relationships are reflected in subsidiaries’ credit risk in CEE countries. Our results suggest that the size and profitability of the parent bank have negative influences, while the liquidity and credit risk of the parent bank have positive influences on the subsidiaries’ credit risk. Moreover, the GDP growth in the parent bank’s country has a negative effect on the credit risk of the subsidiary, while the lending rate and liquidity in the parent bank country cause growth in the credit risk. These results indicate a new channel of international risk transfer from parent bank countries to host countries through foreign-owned banks.     

Commercial banks’ expanding into securities underwriting: The equity market’s risk assessment

Government officials must decide if the payments system and deposit insurance funds would be endangered by allowing commercial banks to underwrite corporate securities. In this study the authors provide evidence on the issue by evaluating the perspectives of equity investors in investment banking concerns. Dealer exposures to capital markets (investment banking and market making) are not perceived to contribute to their marginal riskiness—either systematic or nonsystematic. However, investment exposures to capital markets (merchant banking and principal transactions) add to both systematic and nonsystematic risks of participating firms. Along with the accounting-based previous research, these findings suggest granting new securities powers that are solely dealer-based.     

Empirical analysis of the integration of environmental risks into the credit risk management process of European banks

About 15 years ago, banks started to integrate environmental risks into their credit risk management procedures. In this article, a survey of the European banking sector focusing on the analysis of the integration of environmental risks into all phases of the credit risk management, rating, costing, pricing, monitoring and work‐out, is presented. The integration of environmental risks into the whole credit risk management process is important because only then is an adequate risk management guaranteed. The results show that banks integrate environmental risks especially into the rating phase, but not in all phases of the credit management process, though this is recommendable because these risks influence all phases of the credit management process. Furthermore, significant differences in integrating environmental risks between banks that are signatories of the UNEP statement by banks on the environment and sustainable development and banks that had not signed this agreement so far could be found.

Decomposing the growth in residential land in the United States

This paper decomposes the growth in land occupied by residences in the United States to give the relative contributions of changing demographics versus changes in residential land per household. Between 1976 and 1992 the amount of residential land in the United States grew 47.7% while population only grew 17.8%. At first glance, this suggest an important role for per-household increases. However, the calculations in this paper show that only 24.5% of the growth in residential land area can be attributed to state-level changes in land per household. 37.3% is due to overall population growth, 22.6% to an increase in the number of households over this period, 6% to the shift of population towards states with larger houses, and the remaining 9.6% to interactions between these changes. There are large differences across states and metropolitan areas in the relative importance of these components.

Top performing banks: the benefits to investors

In this study, we examine whether superior accounting performance as reported in the annual ABA Banking Journal Top Performing Banks survey translates into higher investor returns. We observe that the announcement effect is more pronounced during the early years of the survey. For the entire survey period and for later sub-periods in which bank holding companies (BHCs) are ranked based on return on equity (ROE), we observe statistically-significant superior holding period returns against both the S&P 500 index and in some cases a matched sample. These results include raw and risk-adjusted returns as well as buy and hold abnormal returns (BHARs). We obtain similar results after controlling for the market return, size, book-to-market ratio, and momentum factors.     

The double-edged sword effect of diversified operation on pre- and post-loan risk in the government-led Chinese commercial banks

Under the background of China’s deregulation of financial institutions since 2004, Chinese commercial banks have undergone remarkable change from traditional lending activities to universal fee-based activities. This paper explores the effect of diversified operation on bank credit activities. We find that diversification can reduce pre-loan risk but increase post-loan risk. Besides, enhanced disclosure requirement of other comprehensive income can mitigate pre- and post-loan risk under diversified operation. Additionally, in the state-owned commercial banks where government function is primary, diversification reduces both pre- and post-loan risk. This paper aims to reveal the double-edged sword effect of diversification in the Chinese commercial banks which are more government-led.     

Computing systemic risk using multiple behavioral and keystone networks: The emergence of a crisis in primate societies and banks

What do the behavior of monkeys in captivity and the financial system have in common? The nodes in such social systems relate to each other through multiple and keystone networks, not just one network. Each network in the system has its own topology, and the interactions among the system’s networks change over time. In such systems, the lead into a crisis appears to be characterized by a decoupling of the networks from the keystone network. This decoupling can also be seen in the crumbling of the keystone’s power structure toward a more horizontal hierarchy. This paper develops nonparametric methods for describing the joint model of the latent architecture of interconnected networks in order to describe this process of decoupling, and hence provide an early warning system of an impending crisis.     

Measuring scale effects in the allocative profit efficiency

This paper provides an approach to the measurement of the “scale effects” in the allocative profit efficiency. To be specific, we evaluate the improvements of profit that can be accomplished by means of a change in the scale size, once technical efficiency is achieved. New decompositions of the allocative efficiency into a scale effect component and the corresponding residual mix effect component are derived.
