Measuring and explaining the efficiencies of the United Arab Emirates banking system

Using newly collected data from a survey distributed to all banks in the United Arab Emirates (UAE), this article measures economic efficiency in the banking industry, namely allocative, technical, pure technical and scale efficiency. Employing a nonparametric Data Envelopment Analysis (DEA) approach, the study estimates the efficiency for a cross section of the UAE banks in 2004. The results indicate that the dominant source of inefficiency in the UAE banking is stemming from allocative inefficiency rather than technical inefficiency. Furthermore, the main source of the relatively small size, technical inefficiency in the UAE banking industry is not the scale inefficiency but rather pure technical inefficiency. The results further indicate that the UAE banks are able to use their input resources more efficiently when they have more branches, and that newer banks are performing better than older banks on average. Moreover, the results also show that short experiences of employees affect efficiencies negatively and government ownership tends to reduce efficiency (as the government shares increase in the bank, the efficiency scores get lower). Finally, the most interesting results have to do with finding higher average efficiencies in banks that employ more women, more managers and less national citizens of the UAE.     

Explaining efficiency differences among large German and Austrian banks

Cost-efficiency, scale efficiency, and productivity change are estimated by data envelopment analysis; and cost-efficiency is regressed on explanatory variables. No evidence is found for average productivity responding to deregulation over the period studied. State-owned banks are found to be more cost-efficient (likely owing to cheaper funds) and cooperative banks to be about as cost-efficient as private banks. Increasing economies of scale but decreasing economies of scope provide rationale for M&As among banks with similar product portfolios. Interbank and capital market funding is found to be more cost-efficient than deposits when the cost of retail networks is controlled.     

Determinants of banks’ Nerlovian economic efficiency: a DEA-bootstrap approach

ABSTRACT

This study aims to evaluate the Nerlovian economic efficiency of Taiwanese commercial banks and its determinants by assuming the presence of an imperfectly competitive market using a two-stage estimation procedure: Nerlovian economic inefficiency and its components’ price, technical and allocative efficiencies computed and decomposed in the first stage, which are regressed on the explanatory variables with a bootstrapped truncated approach in the second stage. The estimation results show that in the first-stage analysis, the Nerlovian economic inefficiency of banks is primarily due to allocative inefficiency, and indicate the existence of price inefficiency in Taiwan. In the second-stage analysis, the results confirm that both the years in operation of the bank and the ratio of credit loans are the main determinants of banking profit efficiency. In addition, this study not only shows that publicly owned banks contribute to better price efficiency but also proves that loan loss reserve to total assets is negatively associated with technical efficiency. The equity ratio exerts an insignificant favourable impact on allocative efficiency. The findings of this research are essential for bank managers in Taiwan.     

Bus transit technical efficiency using latent class stochastic indirect production frontier

Using an Indirect Production Frontier (IPF), this article examines technical inefficiency within a latent class framework while simultaneously accounting for allocative distortions from operating and capital subsidies. It identifies two latent classes of US public transit systems, one characterized by economies of scale with 16.61% technical inefficiency and the other by diseconomies of scale with 14.16% technical inefficiency. It decomposes technical inefficiency among some of its sources and finds that the incentive tier of federal operating subsidies, regulations regarding years of vehicle use, subsidy-induced allocative distortion from labour overuse relative to capital negatively influence technical inefficiency in all transit systems. For the Latent Class 1 transit systems, the sources of lower technical inefficiency are operating speed, purchased transportation and years-of-vehicle-use regulation. For the Latent Class 2 transit systems, these sources are subsidy-induced capital-labour allocative distortion and the incentive tier component of the federal formula grant.     

The effect of risk-based capital requirements on profit efficiency in banking

The purpose of this paper is twofold: to show how to measure profit efficiency in banking using a newly developed technique, and to use that technique to determine the effect of risk-based capital requirements on the profit performance of US banks. The measure of profit efficiency used captures deviations from profit maximization arising from technical inefficiency, caused by a lack of managerial oversight and allocative inefficiency, which is caused by managers choosing a nonoptimal mix of inputs and outputs. A leverage ratio constraint and a risk-weighted capital ratio constraint are explicitly included in the model, which allows identification of the effect on profits of those constraints. The techniques are applied to random samples of US banks for 1990, 1992, and 1994. The results indicate that allocative inefficiency is a larger source of profit loss than technical inefficiency and that the risk-based capital standards have a significant effect on bank allocative efficiency.     

An Experimental Study of the Effect of Private Information in the Coase Theorem

We investigate, in an experimental setting, the effect of private information on the Coase theorem's predictions of efficiency and allocative neutrality. For a two-person bargaining game, we find significantly more inefficiency and allocative bias in the case of private information compared with the case of complete information. We also find substantial bargaining breakdown, which is not predicted by the Coase theorem. For the case of private information, we reject the Coase theorem in favor of the alternative of a generalized version of the Myerson—Satterthwaite theorem, which predicts inefficiency, allocative bias in the direction of the disagreement point, and some bargaining breakdown.     

Financial deregulation and productivity growth in banking sector: empirical evidence from Bangladesh

This article examines the effects of regulatory reform on productivity growth in the Bangladesh banking industry. We use a unique balanced panel dataset comprising bank-level annual data from the early deregulation year (1984) to the most recent available period (2012) from major commercial banks in Bangladesh. Applying the Färe-Primont index, the paper provides estimates of productivity growth and identifies sources of total factor productivity (TFP) change. Empirical results show the sample banks have experienced positive TFP change after the financial deregulation. On average, TFP growth is higher in private banks than their public sector counterparts in the post-reform period. In addition, the decomposition analysis shows technological progress is the main driver of productivity change. Similar results are obtained by using the stochastic frontier analysis (SFA). Thus, empirical results remain robust irrespective of the methodology used. The regression analysis finds a positive technical change in the first stage of the reform program, i.e. during the transition period, as leading banks employ advanced technology to compete with potential new entrants. The result also shows that the banking industry still remains concentrated within the state-owned banks.     

Measurement of technical and allocative efficiencies using a CES cost frontier: a benchmarking study of Japanese transmission-distribution electricity

This paper estimates the technical and allocative inefficiencies of the transmission-distribution sector of Japanese electric utilities using a panel data during the 1981–1998 period. A stochastic production frontier of the CES form is jointly estimated with input demand equations. Taking advantage of the self-duality, we retrieve the cost frontier by which the impacts of technical and allocative inefficiencies on costs and input demands are measured. The estimated elasticity of substitution is significantly different from unity in favor of the CES specification over the Cobb–Douglas. The results show that observed costs are 9 to 48% higher than the efficient level; technical inefficiency raises costs by 1 to 28%, while allocative inefficiency does so by 8 to 30%. Although their impacts on costs are similar, technical inefficiency more fluctuates so the differences in the performance of utilities are mainly due to technical inefficiency. We also find a substantial over-utilization of capital for all utilities.

CUSTOMER TYPE AND BANK EFFICIENCY IN POLAND: IMPLICATIONS FOR EMERGING MARKET BANKING

Bank efficiency studies on emerging markets tend to show that foreign banks are more cost-, profit-, and operationally efficient than statE-owned or domestic private banks. They also show that large banks are more efficient than small banks. Using a parametric approach to measuring efficiency, this article finds that foreign banks servicing foreign and business customers are more cost-efficient and less profit-efficient than other banks in Poland. Additionally, evidence of cost economies and profit diseconomies of scale are found. These results have implications for regulatory policies focused on promoting efficiency in the banking systems of emerging markets.     

中国渐进改革成本与国有银行财务重组

中国渐进改革的平稳推进得益于新增改革成本能很快地被财政支付或通过国有银行转移,对渐进改革走势影响更大的是被转移至银行的存量成本。实证数据显示,国有银行财务重组中的不良资产处置过程客观上形成了对这一成本的发现机制,但现行的财务重组方案并没有对所有成本进行最终支付,而大量采取了“后摊”与“隐性负债”的处置方式,这是中国渐进式改革的特征体现,其结果是改革成本向国家财政与中央银行的再次转移。中央银行作为“政府的银行”承担改革成本有其现实的必要性和理论的可行性,但由此造成的估值损失应该及时进行确认和记录的会计操作,中央财政预算要反映央行因参与财务重组而导致的实际资本下降。

Privatization,foreign bank entry and bank efficiency in Croatia: a Fourier-flexible function stochastic cost frontier analysis

Using bank balance sheet data for Croatia for 1994 to 2000, this study estimates a Fourier-flexible frontier cost function. Specification tests indicate that the stochastic frontier model with a Fourier-flexible form with a truncated normal distribution of the inefficiency term allowing for time varying cost efficiency is preferred. The results show that new private and privatized banks, contrary to some expectations, are not the most efficient banks through most of the period. Privatization also does not seem to have an immediate effect on improved efficiency. However, better cost efficiency is associated with a lower likelihood of failure, suggesting that better risk management and better cost management are signs of better management in general. Finally, foreign banks have substantially better efficiency scores than all categories of domestic banks.     

The Efficiency of China's Banking Industry and the Determinants

The recent global financial crisis highlights the importance of a sound financial sector for economic development. This paper evaluates the economic efficiency of China's banking industry and investigates the determinants of this efficiency. Our analysis shows that the average economic efficiency of joint-stock commercial banks is highest, followed by the ‘Big Four’ state-owned commercial banks and city commercial banks. The economic inefficiency of these banks during the past 15 years was mainly caused by technical inefficiency, and this technical inefficiency was mainly caused by scale inefficiency. Using the scores of efficiency as dependent variables, the paper also comprehensively studies the impact of (1) the characteristics of individual banks, (2) the characteristics of the whole banking industry and (3) macroeconomic factors on banking efficiency. The results suggest a number of factors that banks can work on to improve efficiency and lend support to deepening reforms in the Chinese banking industry, including regulatory reforms that require capital adequacy in a more strict way, reforms that introduce more competition and, more broadly, reforms that aim at establishing institutions that can truly commercialize Chinese banks. Last but not least, the efficiency of banking depends on healthy growth of the overall economy.     

Determinants of bank cost efficiency in transition economies: evidence for Latin America,Central and Eastern Europe and South-East Asia

In this study, we adopt Wang’s (2002) heteroscedastic stochastic frontier model, which allows us to investigate bank cost efficiency and to measure the marginal effects of some variables on both the level and the variability of inefficiency. In recent years, the financial crisis has significantly affected the banking systems of the transition countries. Hence, the efficiency is of major importance for the stability of the banks. Regarding the determinants of efficiency, we find evidence that banks that follow a more cautious strategy, characterized by lower risk appetite and average expectations on profitability, have higher cost efficiency. We also find that traditional deposit-taking and loan-making still remain the most efficient activity of the banks. Additionally, the results showed that a higher Gross Domestic Product growth rate implies an increase in the inefficiency level, indicating an unsustainable bank management behaviour, which in periods of economic growth adopts policies that can generate inefficiency in order to gain market share and to obtain higher bonuses. Country cost efficiency results show significant differences. The banking systems in transition countries in South Eastern Asia appear to have a higher cost efficiency level. Also, the effects of the financial crisis were less significant in this region.     

Determinants of the allocative,cost and scope efficiencies of Indian banks

ABSTRACT

This study aims to investigate the impact of competition on determinants of allocative, scope and cost efficiencies of Indian scheduled commercial banks (SCBs). Specifically, the study, analyzes the impact of the second round of licensing on the efficiency of Indian SCBs. This is the first paper to measure scope efficiency of Indian banks and analyze its determinants. A two-stage analysis is performed on a balanced panel dataset of Indian SCBs for the period 1999–2016. In the first stage, the allocative, cost and scope efficiencies for each bank are estimated following the data envelopment analysis approach. In the second stage, internal determinants of the stated efficiency measures are estimated following the system of the generalized method of moments approach. The findings suggest that competition has not resulted in enhancing the efficiency of Indian SCBs. Among factors that can influence efficiency, it is seen that size does matter. Larger banks can enhance the efficiency of SCBs. It is also seen that having more foreign banks improves the overall efficiency of SCBs. However, before embarking on further rounds of licensing, the study posits that market-driven correction to succeed, it is imperative to address sunspots in the form of investor or borrower repression.     

Sources of investment inefficiency: The case of fixed-asset investment in China

This study attempts to measure the inefficiency associated with aggregate investment in a transitional economy. The inefficiency is decomposed into allocative and technical inefficiency based on standard production theory. Allocative inefficiency is measured by the deviation of actual investment from the theoretically desired investment demand. Institutional factors are then identified as part of the driving force of the deviation. The resulting model is applied to Chinese provincial panel data. The main findings are: Chinese investment demand is strongly receptive to expansionary fiscal policies and inter-provincial network effects; the tendency of over-investment remains, even with signs of increasing allocative efficiency and improving technical efficiency.

Efficiency of labour use in the Swedish banking industry: a stochastic frontier approach

The purpose of this paper is to analyse the impact of the deregulation of the Swedish banking industry in the mid-1980s, and the consequent banking crisis, on productive efficiency and productivity growth in the industry. An unbalanced panel of Swedish banks is studied over the period, 1984 to 1995. A total of 1275 observations are analysed for 156 banks that were observed for between two and twelve years. We adopt a translog stochastic frontier model to estimate the labour-use requirements in terms of the variables, loans, deposits, guarantees, number of branches and total inventories, together with the year of observation. The inefficiency effects in the labour-use frontier are modelled in terms of the number of branches, total inventories, the type of bank and year of observation. The technical inefficiencies of labour use of Swedish banks were found to be significant, with mean inefficiencies per year estimated to be between about 8 and 15 per cent over the years of study. However, the confidence interval predictions for these inefficiencies were found to be quite wide. First version received: August 1998/Final version received: April 2000     

From scratch to efficiency gains after a financial crisis? A tale of a restructured banking system

We study the efficiency of the Argentine banking system after the 2001–2002 crisis. The financial system had to be restructured from scratch and recovered jointly with the economy, but its productivity and average cost levels have been stagnant since 2007. The analysis includes efficiency frontier estimations for retail banks and a comparison of subsamples for different categories of banks for the period 2005–15. We try to determine whether public banks are more efficient than private ones, whether privatized are more efficient than always private, as well as national versus foreign entities. Our findings show a modest average efficiency of the system and quite similar efficiency rankings for the different groups of banks. On average, public tend to be slightly more cost efficient than private, and national are slightly more efficient than foreign.     

Stochastic Cost Frontier and Inefficiency Estimates of Public and Private Universities: Does Government Matter?

Stochastic frontier analysis is used to estimate operating cost inefficiencies of public and private non-profit universities in the U.S. while also accounting for the possible effects arising from differences in the degree of government ownership. Using panel data for four academic years, 2005?C2009, inefficiencies are estimated under two model specifications. Results indicate that public universities are more cost efficient when environmental factors influence cost frontiers but private universities are the cost efficient institutions when those factors are determinants of inefficiency. Increased government funding does matter and increases private sector inefficiency but offers some efficiency improvements among public universities. Following the global financial crisis, there is evidence indicating a considerable slowdown in the inefficiency growth among both public and private universities.
