x efficiency in australian banking an empirical investigation this paper empirically investigates the x eaciency technical and allocative in australian banks a non parametric method of data envelopment analysis dea has been used to arrive at the eaciency scores banks in this sample were found to have low levels of overall eaciency compared with the banks in the european countries and in the us the results indicate that as a source of overall ineaciency the technical component was more important than the allocative component thus the ineaciency in australian banks can be attributed to wasting of inputs technical ineaciency rather than choosing the incorrect input combinations allocative ineaciency domestic banks were found to be more eacient than foreign owned banks the study has important implications such as guiding the government policy regarding deregulation and mergers since the study pinpoints the sources of ineaciency it would also help banks with strategic planning 2001 elsevier science b v all rights reserved

a comparative study of efficiency in european banking this paper investigates whether there has been an improvement in and convergence of productive efficiency across european banking markets since the creation of the single internal market using efficiency measures derived from dea estimation the determinants of european bank efficiency are evaluated using the tobit regression model approach the established literature on modelling the determinants of bank efficiency is then extended by recognizing the problem of the inherent dependency of dea efficiency scores when used in regression analysis to overcome the dependency problem a bootstrapping technique is applied overall the results suggest that since the eu s single market programme there has been a small improvement in bank efficiency levels although there is little evidence to suggest that these have converged the results also suggest that inference on the determinants of bank efficiency drawn from non bootstrapped regression analysis may be biased and misleading

banking efficiency and competition in low income countries the case of uganda there is a concern that the state dominated inefficient and fragile banking systems in many low income countries especially sub saharan africa are a major hindrance to economic growth in this context this article systematically analyses the impact of the far reaching banking sector reforms undertaken in uganda on banking sector competition and efficiency using models of banking competition and efficiency that have been predominantly estimated in industrial countries we find that the level of competition has significantly increased and has been associated with a rise in efficiency of the sector moreover on average larger banks and foreign owned banks are more efficient than others while smaller banks have fallen back in efficiency with the increase in competitive pressures

a non radial dea approach to measuring environmental performance data envelopment analysis dea has gained great popularity in environmental performance measurement because it can provide a synthetic standardized environmental performance index when pollutants are suitably incorporated into the traditional dea framework past studies about the application of dea to environmental performance measurement often follow the concept of radial efficiency measures in this paper we present a non radial dea approach to measuring environmental performance which consists of a non radial dea based model for multilateral environmental performance comparisons and a non radial malmquist environmental performance index for modeling the change of environmental performance over time a case study of oecd countries using the proposed non radial dea approach is also presented it is found that the environmental performance of oecd countries as a whole has been improved from 1995 to 1997

the comparative efficiency performance of small and large us commercial banks in the pre and post deregulation eras the purposes of this paper are twofold first to employ a flexible non parametric approach to contrast the productive efficiency of a sample of small and large banks in order to examine the relationship between size and productive performance in the banking industry second to investigate whether the relative efficiency performance of small and large banks has changed following the changes in the banking environment in the 1980s and to contrast the rate of technological change achieved by these two groups of banks over this time period the findings based on group specific frontiers suggest that in the pre deregulation environment small banks were more efficient than the large banks while in the deregulated environment small and large banks were equally efficient moreover the dispersion in the efficiency measures of the small banks is found to have increased substantially while that of the large banks changed little over the sample period

productive efficiency performance of minority and nonminority owned banks a nonparametric approach abstract this study examines the efficiency performance of the minority owned banks mobs as multiproduct firms relative to that of the nonminority banks nmobs using a highly flexible nonparametric approach since mobs and nmobs employ distinct technologies the efficiency indices for the two groups are derived relative to their respective group specific frontiers and are contrasted to shed light on the ownership efficiency relationship the mob sample is then disaggregated and the intra group efficiency differentials are investigated the findings support the hypothesis that abstracting the regional regulatory size and maturity characteristics of banks efficiency differentials between mobs and nmobs are statistically insignificant

the impact of macroeconomic and regulatory factors on bank efficiency a non parametric analysis of hong kong s banking system abstract this paper assesses the relative technical efficiency of institutions operating in a market that has been significantly affected by environmental and market factors in recent years the hong kong banking system these environmental factors are specifically incorporated into the efficiency analysis using the innovative slacks based second stage tobit regression approach advocated by fried et al fried h o schmidt s s yaisawarng s 1999 incorporating the operating environment into a nonparametric measure of technical efficiency journal of productivity analysis 12 249 267 a further innovation is that we also employ tone s tone k 2001 a slacks based measure of efficiency in data envelopment analysis european journal of operational research 130 498 509 slacks based model sbm to conduct the data envelopment analysis dea in addition to the more traditional approach attributable to banker charnes and cooper bcc banker r d charnes a cooper w w 1984 some models for estimating technical and scale efficiencies in data envelopment analysis management science 30 1078 1092 the results indicate high levels of technical inefficiency for many institutions considerable variations in efficiency levels and trends across size groups and banking sectors and also differential impacts of environmental factors on different size groups and financial sectors surprisingly the accession of hong kong to the people s republic of china episodes of financial deregulation and the 1997 1998 south east asian crisis do not seem to have had a significant independent impact on relative efficiency however the results suggest that the impact of the last mentioned may have come via the adverse developments in the macroeconomy and in the housing market

efficient energy saving targets for apec economies abstract energy saving target ratios estr for 17 apec economies during 1991 2000 are computed in a total factor framework all nominal variables are transformed into real variables by the purchasing power parity ppp at the 1995 price level the data envelopment analysis dea approach is used to find the energy saving target est for apec economies without reducing their maximum potential gross domestic productions gdps in each year energy labor and capital are the three inputs while gdp is the single output our major findings are as follows 1 china has the largest est up to almost half of its current usage 2 hong kong the philippines and the united states have the highest energy efficiency 3 the energy efficiency generally increases for apec economies except for canada and new zealand 4 chile mexico and taiwan have significantly improved their energy efficiency in the last 5 years 5 an inverted u shape relation exists between per capita est and per capita gdp 6 estr has a positive relation with the value added percentage of gdp of the industry sector and a negative relation with that of the service sector

productivity growth in large us commercial banks the initial post deregulation experience abstract we explore productivity growth for a group of 201 large us commercial banks over the initial post deregulation period from 1984 to 1990 using data envelopment analysis dea we measure productivity growth using malmquist productivity indexes and isolate the contributions of technical change technical efficiency change and scale change to productivity growth we find overall productivity growth at the rate of about 4 5 per year on average but productivity declined by 7 61 between 1984 and 1985 and by 0 33 between 1988 and 1989 our second stage panel regressions reveal that larger asset size and specialization of product mix associate with higher productivity growth while higher equity to assets associates with lower productivity growth

the effects of ownership on bank efficiency in latin america in recent years many countries have privatised their state owned banks and encouraged foreign investment this article investigates the roles of state and private ownership and foreign and domestic ownership on the performance of banks across latin america using a range of financial and economic ratios data envelopment analysis dea and regression modelling the study reveals that by 2001 there was surprisingly little difference in performance between state owned and privately owned banks and between foreign and domestically owned banks the study also reports significantly different levels of bank performance in different latin american countries suggesting that country differences outweighed ownership differences in explaining performance

using data envelopment analysis for estimating energy saving and undesirable output abatement a case study in the organization for economic co operation and development oecd countries abstract environmental protection is one of the main concerns of the international community countries show meticulous attention to environmental issues by considering eco efficiency the eco efficiency evaluation of countries is a complex and multidisciplinary topic data envelopment analysis has widely been applied to measure the eco efficiency of organization for economic co operation and development countries in previous studies energy inputs have not been contemplated the subject becomes more important when there are non discretionary factors in this paper the eco efficiency of countries in the organization for economic co operation and development is assessed given energy inputs undesirable outputs and non discretionary factors to this end slack based and range adjusted measures are extended also new environmental indices are introduced the relationship between consumption of energy inputs and production of undesirable outputs can be addressed by two new environmental indices spearman correlation test indicates a direct and positive relationship between potential of energy saving and potential of undesirable output abatement france germany luxemburg norway sweden and the united kingdom are recognized as eco efficient countries south korea and italy have the highest and lowest potential for energy saving respectively poland and iceland are countries with the highest and lowest potential for undesirable output abatement respectively it can be concluded that countries producing high undesirable outputs may not operate eco efficiently and thus have an extreme potential to save the optimum energy moreover countries consuming low energy may operate eco efficiently and have a low potential to reduce undesirable outputs

banking deregulation and allocative efficiency in pakistan abstractthis article examines the impact of deregulation policies on allocative efficiency of banks in pakistan it investigates whether deregulation has impacted the pattern of allocative efficiency of banks and explores which bank ownership segment has been more responsive it uses data from 1991 to 2005 and explicitly models allocative inefficiency by using the translog shadow cost share system empirical results show that overregulation and imperfect market structure hampers the ability of banks to make competitive decisions we find evidence of allocative inefficiency leading to over utilization of labour and deposits vis a vis operating cost empirical results for time varying allocative efficiency show declining levels of allocative inefficiency for state owned and private banks in post reform period deregulation policies induce state owned banks to decrease over utilization of labour relative to deposits and operating cost while private banks succeed in using operating cost closer to optimal leve

dea radial measurement for environmental assessment and planning desirable procedures to evaluate fossil fuel power plants abstract energy policy depends on a proper use of methodology in guiding a large energy issue such as the global warming and climate change dea is one of such methodologies that are often used for preparing environmental policy which is closely linked to various energy issues unfortunately the use of dea applied to environmental policy is insufficient often misguiding policy makers and other individuals who are involved in energy issues this study provides three guidelines for a use of dea in preparing environmental assessment first it is important to prepare both primal and dual formulations to confirm whether information regarding all production factors i e inputs desirable and undesirable outputs is fully utilized in dea assessment second dea has model variations in radial and non radial measurements it is necessary for us to examine environmental issues by different models in order to avoid a methodological bias existing in those empirical studies finally dea environmental assessment needs to incorporate the concept of natural and managerial disposability the natural disposability indicates that a firm negatively adapts a regulation change on undesirable outputs in contrast the managerial disposability indicates that a firm positively adapts the regulation change because the firm considers the regulation change as a new business opportunity

eco efficiency and convergence in oecd countries this paper assesses the convergence in eco efficiency of a group of 22 oecd countries over the period 1980 2008 in doing so three air pollutants representing the impact on the environment of economic activities are considered namely carbon dioxide text co 2 nitrogen oxides text no mathrm x and sulphur oxides text so mathrm x furthermore eco efficiency scores at both country and air pollutant specific level are computed using data envelopment analysis techniques then convergence is evaluated using the recent approach by phillips and sul econometrica 75 1771 1855 2007 which tests for the existence of convergence groups first we find that eco efficiency has improved over the period with the exception of text no mathrm x emissions second switzerland is the most eco efficient country followed by some scandinavian economies such as sweden iceland norway and denmark in contrast southern european countries such as portugal spain and greece in addition to hungary turkey canada and the united states are among the worst performers finally we find that both the most eco efficient countries and the worst tend to form clubs of convergence

the effects of shared atm networks on the efficiency of turkish banks this study investigates whether forming shared atm networks has yielded positive benefits for banks in turkey by increasing their productive efficiency using a data envelopment analysis dea approach pure technical and scale efficiency scores of turkish banks are estimated and analysed for the period 2000 2003 the results suggest that although it is possible to realize positive effects through atm sharing arrangements there are multiple factors that determine which banks realize such benefits the geographical distribution of shared atms between urban and rural markets and the level of competition between banks within urban areas are shown to be important determinants of differences in bank efficiency this discrepancy between the gains associated with atm sharing may have important implications concerning the adoption and sharing of new technology by banks in developing countries

financial liberalization and bank efficiency a comparative analysis of india and pakistan this paper provides a comparative analysis of the evolution of the technical efficiency of commercial banks in india and pakistan during 1988 1998 a period characterized by far reaching changes in the banking industry brought about by financial liberalization data envelopment analysis is applied to two alternative input output specifications to measure technical efficiency and to decompose technical efficiency into its two components pure technical efficiency and scale efficiency the consistency of the estimated efficiency scores are checked by examining their relationship with three traditional non frontier measures of bank performance in addition the relationship between bank size and technical efficiency is examined it is found that the overall technical efficiency of the banking industry of both countries improved gradually over the years especially after 1995 unlike public sector banks in india public sector banks in pakistan witnessed improvement in scale efficiency only it is also found that banks are relatively more efficient in generating earning assets than in generating income this is attributed to the presence of high non performing loans in addition it is found that the gap between the pure technical efficiency of different size groups has declined over the years

realized volatility transmission between crude oil and equity futures markets a multivariate har approach this paper differs from extant literature because it studies volatility co movements with a multivariate orthogonalized har model a flexible specification for the time series of realized volatility which is able to identify short mid and long term spillover effects we examine volatility transmission mechanisms using high frequency data of the stock index futures on s p 500 nikkei 225 ftse 100 and the futures on the west texas intermediate crude oil during the period from september 2002 to september 2012 considering the full sample the short term volatility of the equity futures contains information about future oil volatility incremental to the information inherent in the time series of oil volatility on the other hand weekly and monthly volatilities do not exhibit a significant spillover effect breaking the whole sample into three subsamples no significant granger causalities are observed in the pre crisis period while in the crisis time and its aftermath we document that the us and uk equity market volatilities to granger cause the oil futures volatility which itself leads the japanese market in terms of magnitude we observe an increase in the short term volatility spillover over time studying the residuals of the har transmission models within a ccc dcc garch framework reveals increasing instantaneous correlation between the energy and equity volatilities in the course of time

the impact of liberalization on the productive efficiency of indian commercial banks abstract we examine the productive efficiency of 70 indian commercial banks during the early stages 1986 1991 of the ongoing period of liberalization we use data envelopment analysis to calculate radial technical efficiency scores we then use stochastic frontier analysis to attribute variation in the calculated efficiency scores to three sources a temporal component an ownership component and a random noise component we find publicly owned indian banks to have been the most efficient followed by foreign owned banks and privately owned indian banks we also find a temporal improvement in the performance of foreign owned banks virtually no trend in the performance of privately owned indian banks and a temporal decline in the performance of publicly owned indian banks we attempt to explain these patterns in terms of the government s evolving regulatory policies

do lenders favor politically connected firms rent provision in an emerging financial market corruption by the politically connected is often blamed for economic ills particularly in less developed economies using a loan level data set of more than 90 000 rms that represents the universe of corporate lending in pakistan between 1996 and 2002 we investigate rents to politically connected rms in banking classifying a rm as political if its director participates in an election we examine the extent nature and economic costs of political rent provision we nd that political rms borrow 45 percent more and have 50 percent higher default rates such preferential treatment occurs exclusively in government banks private banks provide no

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

impact of financial reforms on efficiency of state owned private and foreign banks in pakistan this article uses a unique bank level data from 1991 to 2000 and evaluates how financial reforms affect banking efficiency of domestic and foreign banks in pakistan the results suggest that banking efficiency falls during initial reform period when banks adjust to enhanced competition but increases in more advanced stages of reform while in general foreign and private banks show superior efficiency and factor productivity than do state owned banks the relative performance of foreign banks worsens after the consolidation stage of the financial reforms is over we show the importance of link between bank size asset quality and bank branches with efficiency indexes and also note that every 10 increase in share of nonperforming to total loans decreases banking efficiency by 6 to 10

economies of scale technical change and persistent and time varying cost efficiency in indian banking do ownership regulation and heterogeneity matter abstract banks with different ownership types adjust differently to changes in regulatory environments although this topic has been widely studied all the previous studies fail to control for bank heterogeneity bank specific effects in estimating cost structure and efficiency we propose a model where we control for bank heterogeneity and introduce persistent and time varying inefficiency additionally we incorporate determinants of both persistent and time varying inefficiency as well as production risks furthermore our model allows estimation of different technologies for different ownership types jointly we use this model to analyze the effect of regulation in indian banking we find that private banks have not exhausted their economies of scale foreign banks are operating under diseconomies of scale especially after the reforms and scale economies of state owned banks are unaffected by regulation banks of all ownership types have enjoyed technical progress however foreign banks have benefited the most followed by state owned banks only state banks were able to improve their cost efficiency while private banks and especially foreign banks were lagging behind their cost frontiers

financial sector liberalization bank privatization and efficiency evidence from pakistan abstract the pakistani banking system has been transformed over the past 15 years through liberalization the entry of private banks the privatization of public sector banks and the tightening of prudential regulations the effects of these changes on bank productivity and relative efficiency are investigated using various techniques bank productivity in terms of profits has increased and new entrants have been efficient but the dispersion of efficiency remains wide the privatized banks improved their profit efficiency in the period immediately following their privatization but in the subsequent years only one significantly improved its efficiency whereas the other did not differentiate itself in terms of efficiency from the remaining state owned banks the new private domestic banks generally proved to be among the most efficient and sometimes out performed the foreign banks

deregulation ownership and productivity growth in the banking industry evidence from india this paper analyzes the relationship between deregulation and total factor productivity tfp growth in the indian banking industry using a generalized shadow cost function approach tfp growth is decomposed into a technological change a scale and a miscellaneous component a disaggregated panel data analysis using the population of public and private banks over 1985 96 that covers both pre and post deregulation periods indicates that a significant decline in regulatory distortions and the anticipated increase in tfp growth have not yet materialized following deregulation while private sector banks have improved their performance mainly due to the freedom to expand output public sector banks have not responded well to the deregulation measures

the politics of bank failures evidence from emerging markets this paper studies large private banks in 21 major emerging markets in the 1990s it first demonstrates that bank failures are very common in these countries about 25 percent of these banks failed during the seven year sample period the paper also shows that political concerns play a significant role in delaying government interventions to failing banks failing banks are much less likely to be taken over by the government or to lose their licenses before elections than after this result is robust to controlling for macroeconomic and bank specific factors a new party in power early elections outstanding loans from the imf as well as country specific time independent factors this finding implies that much of the within country clustering in emerging market bank failures is directly due to political concerns

technical scale and allocative efficiencies of turkish banking industry this paper investigates input and output efficiency in the turkish banking industry to understand the impact of size international variables ownership control and governance on profit cost allocative technical pure technical and scale efficiency measures employing a non parametric approach along with a parametric approach we estimate the efficiency of turkish banks over the 1988 1996 period this period allows us to account for the changes in the macro economy and regulatory treatment of the turkish banking industry over time our results suggest that the heterogeneous characteristics of banks have significant impact on their efficiency moreover cost and profit efficiencies of the turkish banks have exacerbated over time results also indicate that the dominant source of inefficiency in turkish banking is due to technical inefficiency rather than allocative inefficiency which is mainly attributed to diseconomies in scale to the extent that they chose an inefficient level of production bank management is responsible for scale inefficient operations however increasing demand for banking services in the nineties fueled by the state s increasing demand for funds to finance chronic budget deficits and high growth policies and the oligopolistic nature of the turkish banking market do not justify scale adjustments our policy suggestions are that the government implement financial reform packages that foster competition in the banking market and that the industry devise incentive schemes to improve managerial efficiency

politicians and banks political influences on government owned banks in emerging markets abstract government ownership of banks is very common in countries other than the united states this paper provides cross country bank level empirical evidence about political influences on these banks it shows that government owned banks increase their lending in election years relative to private banks this effect is robust to controlling for country specific macroeconomic and institutional factors as well as bank specific factors the increase in lending is about 11 of a government owned bank s total loan portfolio or about 0 5 of the median country s gdp per election per government owned bank

slacks based efficiency measures for modeling environmental performance we develop two slacks based efficiency measures for modeling environmental performance on the basis of environmental dea technology of the two measures one is a composite index with a higher discriminating power for modeling economic environmental performance and the other can be used to estimate the impacts of environmental regulations we apply the proposed measures to model the co2 emissions of 30 oecd countries from 1998 to 2002 and present the results obtained

evolution of banking efficiency within an unstable macroeconomic environment the case of turkish commercial banks this paper analyses the efficiency performance of the turkish banking sector between 1988 and 1999 a period characterized by increasing macroeconomic instability the technical and scale efficiencies of turkish commercial banks are measured with the use of nonparametric data envelopment analysis the empirical results suggest that over the sample period both pure technical and scale efficiency measures show a great variation and the sector did not achieve sustained efficiency gains it is also reported that the sector suffers mainly from scale inefficiency and scale inefficiency in turn is due to decreasing returns to scale there are also reported differences in the efficiency performance of commercial banks with different ownership status in addition the relationships between profitability asset quality size and the two definitions of efficiency are considered efficient banks are more profitable and pure technical efficiency and scale inefficiency are positively related to size the trend in th

technical efficiency and scale efficiency in the italian banking sector a non parametric approach measures of technical and scale efficiencies are derived in the italian banking industries by implementing non parametric data envelopment analysis on a cross section of 174 italian banks taken in 1991 the methodology of the parametric and non parametric approaches to measure efficiency are discussed the existence of both technical and allocative efficiency is established this result is robust to modifications in the specification of inputs and outputs suggested by the intermediation approach and by the asset approach in implementing both the intermediation and the asset approach the traditional specification of inputs is modified to allow an explicit role for financial capital in addition regression analysis is used on a bank specific measure of inefficiency to investigate determinants of banks efficiency efficiency is best explained by productive specialization size and to a lesser extent by location
