turkish bank efficiency bayesian estimation with undesirable outputs this paper analyzes the productivity and efficiency of turkish banks from 2002 to 2010 we obtained estimates of efficiency productivity growth and efficiency growth using a bayesian stochastic frontier approach and focused on accounting for non performing loans npls for use in our model specifically we introduce npls as a bad output in an input distance function and estimate a system of non linear equations subject to endogeneity we confirm that the productivity growth of turkish banks was positive over the period of this study which was mainly due to the improvement in technology while efficiency growth continued to be negative over the same period methodologically we also prove that not accounting for npls in estimating the frontier model might seriously distort the efficiency and productivity results the study also provides measures of shadow prices for npl and discusses the results in terms of several interesting trends in turkish banking finally the paper provides efficiency and productivity comparisons between domestic and foreign banks

financial supervision regimes and bank efficiency international evidence abstract there exists a lively debate as for the appropriate architecture of the financial supervision regime with a long list of theoretical advantages and disadvantages associated with each one of its key dimensions the present study investigates whether and how bank profit efficiency is influenced by the central bank s involvement in financial supervision the unification of financial authorities and the independence of the central bank the results show that efficiency decreases as the number of the financial sectors that are supervised by the central bank increases additionally banks operating in countries with greater unification of supervisory authorities are less profit efficient finally central bank independence has a negative impact on bank profit efficiency

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

x efficiency and economies of scale in pension fund administration and investment pension funds operating costs impair pension benefits so it is crucial for pension funds to operate at the lowest cost possible in practice we observe substantial differences in costs per member for dutch pension funds both across and within pension fund size classes this article presents new estimates of scale economies of pension funds and is the first that also measures pension fund x inefficiency we use a unique supervisory data set which distinguishes between administrative and investment costs and apply various approaches and models our estimates show large economies of scale for pension fund administrations but modest diseconomies of scale for investment activities we also found that many pension funds have substantial x inefficiencies for both administrative and investment activities the two kinds of inefficiency differ across types of pension funds therefore most pension funds should be able to improve their cost performance and hence increase pension benefits

the nonparametric risk adjusted efficiency measurement an application to taiwan s major rural financial intermediaries in this article a nonparametric approach is used to incorporate risk into the measurement of technical efficiencies of the major financial intermediaries in rural taiwan risk is treated as a joint but undesirable output given the fact that various regulatory actions may prevent its free disposability three risk indicators nonperforming loans allowance for loan losses and risky assets are employed alternatively in the empirical work results suggest that all three risk constraints are binding regulations on controlling risky assets and loan loss reserves are effective but more burdensome than those on controlling loan quality

competition policy and property rights one of the most controversial general questions in current competition policy is when if ever should competition law require a firm with market power to share its property with its rivals the answer would seem to be very rarely in the view of the supreme court of the united states as expressed in the 2004 trinko case which concerned whether a telecommunications network provider is required by us antitrust law to provide network access to its competitors

patent policy imitation incentives and the rate of cumulative innovation abstract we study an infinite horizon cumulative innovation model in which patents are characterized by their length and the likelihood of being ruled valid in a patent infringement litigation strengthening patent protection via a greater validity or length has two opposing effects on innovation 1 a negative litigation effect due to increasing the litigation threat for future innovators and 2 a positive competition effect due to reducing profit eroding imitation by competitive firms without innovation capacity the optimal innovation maximizing patent policy balances these two opposing effects for moderate patent validity longer remaining lifetime increases innovation due to the competition effect the opposite is true for higher validity for which the litigation effect dominates moderate validity and infinite patent length maximizes innovation when future profits are subject to greater discounting and r d costs are low while strong validity and finite length stimulates more innovation under lower discounting and higher r d costs

multiperson tournaments an experimental examination modern hierarchical organizations like corporations must motivate agents to work hard given their pyramid structure it is not surprising that one commonly used motivator is the promotion tournament in such tournaments agents compete to advance to positions at higher organizational levels though these tournaments are common little research has empirically looked at the interface of organizational structure and tournament design this paper aims to take a step in filling this void by comparing the performance of various tournament designs using controlled laboratory techniques

economic efficiency and downside risk this article investigates the impact of downside risk on cost and revenue efficiency re for a sample of farms downside risk or loss below a certain level of return is a concern regardless of producer risk preferences and thus a suitable measure of risk to use downside risk was measured as the weighted summation of net farm income below the amount needed for unpaid labour during the previous 10 years cost and re were estimated using traditional input and output measures and then re estimated including each farm s downside risk comparisons were made between the efficient farms with and without downside risk and the average for all farms as expected downside risk plays an important role in explaining farm inefficiency failure to account for downside risk overstates inefficiency and can lead to unrealistic expectations in potential efficiency improvements

technological regimes and schumpeterian patterns of innovation this paper proposes that the specific pattern of innovative activities in an industry can be explained as the outcome of different technological learning regimes a technological regime is defined by the particular combination of technological opportunities appropriability of innovations cumulativeness of technical advances and properties of the knowledge base building upon the distinction between schumpeter mark i and schumpeter mark ii industries this paper provides empirical estimates of the relationships between indicators of the schumpeterian patterns of innovation concentration of innovative activities stability in the hierarchy of innovators and importance of new innovators and indicators of the variables defining technological regimes

patentability r d direction and cumulative innovation we present a model of cumulative innovation where firms can conduct r d in both a safe and a risky direction innovations in the risky direction produce quality improvements with higher expected sizes and variances as patentability standards rise an innovation in the risky direction is less likely to receive a patent that replaces the current technology which decreases the static incentive for new entrants to conduct risky r d but increases their dynamic incentive because of the longer duration and hence higher reward for incumbency these together with a strategic substitution and a market structure effect result in an inverted u shape in the risky direction but a u shape in the safe direction for the relationship between r d intensity and patentability standards there exists a patentability standard that induces the efficient innovation direction whereas r d is biased towards against the risky direction under lower higher standards the optimal patentability standard may distort the r d direction to increase the industry innovation rate that is socially deficient

can mergers ensure the survival of credit unions in the third millennium abstract the survival of small financial institutions in the third millennium depends on their competitiveness against large bank rivals accordingly credit unions in australia and the united states have attempted to increase efficiency through mergers our paper uses the data envelopment analysis methodology to evaluate the post merger gains in technical and scale efficiency achieved by 31 australian credit union mergers in 1993 1994 and 1994 1995 relative to non merging credit unions when compared with the only us study of credit union mergers journal of banking finance 23 1999 367 386 our findings suggests that mergers are not associated with improvements in efficiency superior to those achieved by internal growth

controlling for the use of extreme weights in bank efficiency assessments during the financial crisis we propose a method for bank efficiency assessment based on weight restricted dea that limits banks abilities to use extreme weights corresponding to extreme judgements of the risk adjusted prices on funding sources and assets based on a data set comprising the largest european banks during the financial crisis we illustrate the impact of the proposed weight restrictions in two different efficiency models one related to banks funding mix and one related to their asset mix the results show that using a more balanced set of weights tend to reduce the estimated efficiency scores more for those banks which were bailed out during the crisis which confirms the potential bias within standard dea that does not control for extreme weights applied by highly risky banks we discuss the use of the proposed method as a regulatory tool to constrain discretion when complying with regulatory capital benchmarks such as the basel regulatory capital ratios

productivity change in taiwan s farmers credit unions a nonparametric risk adjusted malmquist approach this article proposes an extended three stage dea methodology similar to fried et al 2002 to improve the measurement of productivity growth when the assumption of free disposability of undesirable output does not apply a directional distance function is used to construct adjusted malmquist luenberger productivity indexes which simultaneously account for the impacts of undesirable outputs environmental variables and statistical noise panel data for 263 farmers credit unions fcus in taiwan covering the 1998 2000 periods are employed to illustrate the advantages of this method on average the productivity of taiwan s fcus is found to have deteriorated over the 1998 2000 period although an improvement in efficiency has been observed the major reason for the deterioration is found to be due to the regression of technology

efficiency and risk in taiwan banking sbm super dea estimation in this study we adopt the two data envelopment analysis dea methods including banker charnes cooper bcc and slacks based measure sbm super efficiency to investigate whether a bank s technical efficiency index s results incorporating account risk and not incorporating account risk differ significantly the information is obtained from 43 taiwanese banks for the period 1998 to 2002 we also employ the nonradial and slacks based malmquist total factor productivity tfp index to measure the impact of productivity change on the panel data our empirical results from the dea approach are summarized as follows 1 loan quality factors have an impact on a bank s efficiency in general the bank with a higher degree of problem loans drops down its efficiency by incorporating account risk however the bank with a lower degree of problem loans increases its efficiency by incorporating account risk 2 super efficiency provides a good framework for ranking efficient units 3 based on the nonradial an

the dominance of inefficiencies over scale and product mix economies in banking abstract this study measures and analyzes inefficiencies for all u s banks in 1984 inefficiencies are measured relative to a thick frontier cost function and are found to dominate measured scale and product mix economies most inefficiencies are operational in nature involving the overuse of physical inputs rather than financial involving overpayment of interest also technical inefficiencies proportionate overuse of all inputs dominate allocative inefficiencies improper mix of inputs these results suggest that competitive pressures in banking from deregulation will be focused primarily on banks that do not control costs rather than on those of a particular size or product mix

how well have social economy financial institutions performed during the crisis period exploring financial and social efficiency in spanish credit unions as social economy financial institutions credit unions have traditionally been considered less efficient than traditional banking entities however like banks and savings banks they have to be as efficient and competitive as possible to survive in today s business environment especially at times of crisis to date there have been very few studies on their efficiency and practically none for the crisis period moreover almost all the existing studies assess only financial efficiency without considering their social function this study examines the levels of both financial and social efficiency in spanish credit unions as well as their main determinants during the recent crisis we apply the two stage double bootstrap data envelopment analysis dea methodology based on panel data corresponding to all the credit unions active in spain between 2008 and 2013 the empirical results indicate that financial and social efficiency achieved an acceptable level although on average the former was slightly greater than the latter we also find that both age and merger and acquisition activity were positively influential on the financial efficiency of credit unions but had a significant negative effect on their social efficiency moreover the regional location of such entities and the financial crisis were also crucial determinants of both types of efficiency our findings are therefore useful for all the stakeholders of credit unions to know if these entities have been efficient according to a double bottom line accounting in the crisis period and hence to maintain successful social management that is compatible with satisfactory financial efficiency

cost efficiency and banking performances in a partial universal banking system application of the panel smooth threshold model this paper studies the cost efficiency of bank in a partial universal banking system pubs taiwan instead of assuming one common technology in the bank cost function two technologies are assumed to be imbedded in the cost function fee revenues are used as threshold to divide the banks into two technologies a bank whose fee revenues exceeding the threshold is designated as universal bank technology while falling below the threshold is designated as traditional deposit loan technology the panel smooth transition model is adopted which allows banks to smoothly adjust between the two technologies two criteria are suggested overbanking and the trend toward fee revenues to assess the new model s performances with respect to scale economies the results do find a panel smooth transition model yield more reasonable results than the conventional ols and random effect of panel data approach based on the panel smooth transition model the optimal fixed asset size is around ten billion new taiwan dollars

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

how significant is the alleged unfair advantage enjoyed by state owned banks in germany the european commission argues that the state owned banks in germany enjoy an unfair advantage over the private sector banks in the cost of borrowing funds in the financial markets because of state guarantees that public sector banks are perceived to enjoy this note demonstrates that the blame for the comparatively poor profitability of private sector banks in germany cannot be laid at the door of the relatively cheaper funds that the public sector banks can raise in the wholesale markets copyright 2006 oxford university press

co2 and energy efficiency of different heating technologies in the dutch glasshouse industry this paper uses data envelopment analysis tocompute input based technical efficiencymeasures and co2 and energy technicalefficiency of specialised vegetable firms inthe netherlands over the period 1991 1995 input based scale efficiency is also calculatedfor each firm these efficiency measures aregenerated for firms with different heatingtechnologies the empirical results indicatethat firms use energy quite efficiently and areless efficient in terms of co2 emissions differences in co2 energy efficiencyacross different technologies are not statistically significant in particular firms using traditional heating technologiesare less efficient in terms of co2 scaleadjustments can provide an importantcontribution to further efficiencyimprovements

the impact of islamic banking on the cost efficiency and productivity change of malaysian commercial banks this study employs stochastic frontier analysis sfa to analyse malaysian commercial banks during 1996 2002 and particularly focuses on determining the impact of islamic banking on performance we derive both net and gross efficiency estimates thereby demonstrating that differences in operating characteristics explain much of the difference in costs between malaysian banks we also decompose productivity change into efficiency technical and scale change using a generalized malmquist productivity index on average malaysian banks experience moderate scale economies and annual productivity change of 2 68 with the latter driven primarily by technical change tc which has declined over time our gross efficiency estimates suggest that islamic banking is associated with higher input requirements however our productivity estimates indicate that full fledged islamic banks have overcome some of these cost disadvantages with rapid tc although this is not the case for conventional banks operating islamic windows merged banks are found to have higher input usage and lower productivity change suggesting that bank mergers have not contributed positively to bank performance finally our results suggest that while the east asian financial crisis had a short term costreducing effect in 1998 the crisis triggered a long lasting negative impact by increasing the volume of nonperforming loans

when do stronger patents increase continual innovation under continual innovation greater patent strength expands innovating firms profit against imitation but also shifts profit from current to past innovators we show how the impact of patents on innovation as determined by these two opposing effects varies with industry characteristics when the discount factor is sufficiently high the negative profit division effect is negligible and innovation monotonically increases in patent strength otherwise innovation has an inverted u relationship with patent strength and stronger patents are more likely to increase innovation when the discount factor or the fixed innovation cost is higher we also show how the impact of patents on innovation may change with firms innovation capability and with the intensity of competition from imitators

a study of bank efficiency taking into account risk preferences abstract i use the stochastic cost frontier approach to investigate efficiency of banks operating in the third federal reserve district accounting for the quality and riskiness of bank output in addition to the mean and mode of the conditional distribution of the one sided error term i calculate confidence intervals for the inefficiency measures based on the conditional distribution the results indicate that third district banks are operating at cost efficient output levels and product mixes but are not efficiently using their inputs the second part of the article relates the inefficiency measures to several correlates

spatial allocation and the shadow pricing of product characteristics abstract the paper considers an industry transforming primary commodities farm products into processed commodities food products it focuses on the allocation of embedded characteristics carbohydrate protein etc both across space and among commodities the approach generates a spatial competitive market equilibrium of production consumption transformation and trade for both primary and processed commodities along with the spatial distribution of shadow prices for the product characteristics the model provides a basis for analyzing the allocation and pricing of agricultural products food products and characteristics in spatial markets the empirical usefulness of the model is illustrated in the context of regional resource allocation in the u s dairy sector

the effects of management decisions on agricultural bank failures the assertion that local economic conditions have been responsible for the failures of large numbers of agricultural banks is investigated by pairing solvent and failed banks within rural counties and examining whether balance sheet items alone explain differences in the probability of failure for the two groups of banks estimation of a probit model indicates that higher ratios of loans to assets and agricultural to total loans were associated with higher probabilities of failure banks with higher capital ratios and those affiliated with multibank holding companies had lower probabilities of failure

traditional and nontraditional banking an information theoretic approach abstract this paper uses a multiproduct approach to analyze the costs of a sample of large banks where bank outputs are measured to account for the different types of information produced by banks diseconomies of scope are found between traditional banking activities of originating and monitoring loans and nontraditional activities of loan selling and buying this suggests maintaining fire walls between commercial bank functions and investment bank functions after the glass steagall act is repealed will not sacrifice joint production economies it also suggests that arguments for repeal of the act based on the existence of such economies are ill founded

inefficiency and heterogeneity in turkish banking 1990 2000 recent studies have stressed the importance of privatization and openness to foreign competition for bank efficiency and economic growth we study bank efficiency in turkey an emerging economy with great heterogeneity in bank types and ownership structures earlier studies of turkish banking had three limitations i excessive reliance on cost function frontier analyses wherein volume of loans is a measure of banking output ii pooling all banks or imposing ad hoc heterogeneity assumptions and iii lack of a comprehensive panel data set for proper analysis of productivity and heterogeneity we use an estimation classification procedure to find likelihood driven classification of bank technologies in an 11 year panel in addition we augment traditional cost frontier analysis with a labour efficiency analysis we conclude that state banks are not particularly inefficient overall but that they do utilize labour inefficiently this partially supports recent calls for privatization we also conclude that special finance houses or islamic banks utilize the same technology as conventional domestic banks and do so relatively efficiently this suggests that they do not cause harm to the financial system finally we conclude that foreign banks utilize a different technology from domestic ones this suggests that one should not overstate their value to the financial sector copyright 2005 john wiley sons ltd

the determinants of cost efficiency in cooperative financial institutions australian evidence abstract previous studies of efficiency in cooperative financial institutions assume subsidies to be a normal part of business operations using a sample of australian credit unions cus this paper shows that ignoring subsidies biases estimates of cost efficiency and efficiency rankings time varying cost efficiency is estimated using stochastic frontier and generalised within approaches and compared with the distribution free df approach assuming constant efficiency despite significant industry rationalisation average efficiency shows little improvement over the period 1985 1993 however efficiency rankings change considerably second stage regressions suggest bond type size age average deposit size and interest rate spreads are significant determinants of relative cost efficiency

productivity and efficiency change and shareholder value evidence from the spanish banking sector productivity change and shareholder value have been analysed in the banking sector in the last few years although it should be noted that these two important aspects have been studied separately in this regard the main contribution of our study is to link these two lines of research by verifying whether those banks characterized by higher levels of efficiency and productivity change have a higher shareholder value to measure changes in efficiency and productivity we use the malmquist nonparametric technique which is calculated from data envelopment analysis dea linear programming approach the malmquist total factor productivity index enables separation of the catching up effect i e changes over time in technical efficiency from technological change i e the shift of best practice frontier over time due to technological progress our results for a sample of listed spanish banks in the period 2000 to 2004 confirm that those banks with higher efficiency and productivity changes have a higher

a study on long run inefficiency levels of a panel dynamic cost frontier under the framework of forward looking rational expectations abstract this paper aims to provide a theoretical underpinning of the dynamic efficiency model pioneered by ahn s c good d h sickles r c 2000 estimation of long run inefficiency levels a dynamic frontier approach econometric reviews 19 461 492 in the context of a quadratic loss function this paper formulates a multi period forward looking rational expectations model on the evolution of the technical inefficiency level which correctly produces a dynamic panel data model the model is illustrated using panel data of 112 french banks encouraging evidence of superiority in favor of the model is reached substantial cost inefficiency prevails in this industry where the constituent banks are characterized as having volatile adjustment speeds toward their long run steady states the sample banks exhibit increasing returns to scale and product mix economies

antitrust in innovative industries we study the effects of antitrust policy in industries with continual innovation antitrust policies that restrict incumbent behavior toward new entrants may have conflicting effects on innovation incentives raising the profits of new entrants but lowering those of continuing incumbents we show that the direction of the net effect can be determined by analyzing shifts in innovation benefit and supply holding the innovation rate fixed we apply this framework to analyze several specific antitrust policies we also show that in some cases the tension does not arise and policies that protect entrants necessarily raise the rate of innovation

specification and estimation of production risk risk preferences and technical efficiency this article deals with specification and estimation of risk preferences production risk and technical inefficiency it makes contribution in three separate areas of production economics first we model producers attitude toward risk and derive risk preference functions without assuming any parametric form of the utility function and any distribution of the error term representing production risk when risk arises from production uncertainty and technical inefficiency second the standard production risk model is extended to accommodate technical inefficiency and producers attitude toward risk finally the technical efficiency model is generalized to accommodate production risk and producers attitude toward risk copyright 2002 oxford university press

applying data envelopment analysis in analysing the organizational change for credit departments of farmers associations in taiwan this study attempts to apply the data envelopment analysis to approach the performance of the credit departments of farmers associations in taiwan based on the structure of the data envelopment analysis approach this study measures the relative efficiency for credit departments of farmers associations in taiwan via resource redistribution when the amount of resource is fixed it can be distributed to each unit within an organization in a better way it is intended to find the possible improvements for those inefficient credit departments of farmers associations the empirical results show that the overall efficiency scores of the teams indicate is not best and scale for credit departments of farmers associations in taiwan is relatively small it implies that the reorganization of the credit departments of farmers associations may be appropriate if more efficient organization is to be pursued finally the reorganization of the credit departments of farmers associations are studies evidences show

threshold effects of financial status on the cost frontiers of financial institutions in nondynamic panels this article applies hansen s 1999 2000 threshold regression model to estimate translog cost frontiers in the hope of shedding light on the banking industry s production processes and the extent of its technical efficiency te the threshold technique allows for the existence of multiple technologies of production distinguished by an exogenous threshold variable strong evidence of multiple technologies is found in the industry irrespective of which financial indicator as constructed by factor analysis defines the threshold variable cost savings and scale economies among the various underlying technologies are compared herein we also highlight the differences between the threshold results and the conventional cost frontier

malmquist indices of productivity growth during the deregulation of norwegian banking 1980 89 productivity growth during the deregulation of the norwegian banking industry is studied within the framework of data envelopment analysis which explicitly allows for multiple outputs introducing malmquist indices for productivity growth total growth can be decomposed into frontier growth and change in each bank s distance to the frontier both the total growth index and its components can be consistently chained over time we find productivity regress at the average bank prior to the deregulation but rapid growth when deregulation took place deregulation also led to less dispersion of productivity levels within the industry

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

enjoying the quiet life under deregulation evidence from adjusted lerner indices for u s banks abstract the quiet life hypothesis posits that firms with market power incur inefficiencies rather than reap monopolistic rents we propose a simple adjustment to lerner indices to account for the possibility of forgone rents to test this hypothesis for a large sample of u s commercial banks we find that adjusted lerner indices are significantly larger than conventional lerner indices and trending upward over time instrumental variable regressions reject the quiet life hypothesis for cost inefficiencies however lerner indices adjusted for profit inefficiencies reveal a quiet life among u s banks

what is the impact of bankrupt and restructured loans on japanese bank efficiency the japanese banking system provides a distinctive platform for the examination of the long lasting effect of problem loans on efficiency we measure technical efficiency by modifying a translog enhanced hyperbolic distance function with two undesirable outputs identified as problem loans and problem other earning assets our unique database allows us to distinguish between bankrupt and restructured loans to investigate the underlying causality between these loans and efficiency from the flexible panel vector autoregression specification primary results reveal that bankrupt loans have a positive impact on efficiency related to the moral hazard skimping hypothesis with the causality originating from bankrupt loans in contrast findings for the relationship between restructured loans and efficiency support the bad luck hypothesis

economic efficiency adjusted for risk preferences abstractthis study investigates the impact of risk preferences on cost and revenue efficiency for a sample of farms risk preference scores were used to measure risk aversion cost and revenue efficiency were estimated using traditional input and output measures and then re estimated including each farm s risk preference score comparisons were made between farms with and without a change in efficiency when each farm s risk preference was included in the analysis as expected risk preference plays an important role in explaining farm inefficiency failure to account for risk preferences overstates inefficiency particularly for slightly risk averse and risk neutral farms

financial freedom and bank efficiency evidence from the european union this paper investigates the dynamics between the financial freedom counterparts of the economic freedom index drawn from the heritage foundation database and bank efficiency levels we rely on a large sample of commercial banks operating in the 27 european union member states over the 2000s after estimating bank specific efficiency scores using data envelopment analysis dea we develop a truncated regression model combined with bootstrapped confidence intervals to test our main hypotheses results suggest that the higher the degree of an economy s financial freedom the higher the benefits for banks in terms of cost advantages and overall efficiency our results also show that the effects of financial freedom on bank efficiency tend to be more pronounced in countries with freer political systems in which governments formulate and implement sound policies and higher quality governance

measuring efficiency at u s banks accounting for heterogeneity is important abstract estimates of bank cost efficiency can be biased if bank heterogeneity is ignored i compare x inefficiency derived from a model constraining the cost frontier to be the same for all banks in the u s and a model allowing for different frontiers and error terms across federal reserve districts i find that the data reject the single cost function model x inefficiency measures based on the single cost function model are on average higher than those based on the separate cost functions model the distributions of the one sided error terms are wider for the single cost function model than for the separate cost functions model and the ranking of districts by the level of x inefficiency differs in the two models the results suggest it is important when studying x inefficiency to account for differences across the markets in which banks are operating and that since x inefficiency is by construction a residual it will be particulary sensitive to omissions in the basic model

data transformations in dea cone ratio envelopment approaches for monitoring bank performances abstract cone ratio dea data envelopment analysis models are suggested for monitoring and or early warning systems to be used by bank regulatory agencies illustrative examples are developed from data on 1984 and 1985 performances of the 16 largest banks in texas five large non texas banks are introduced as excellent performers to help evaluate these texas banks in terms of their risk coverage as well as efficiency cone ratio envelopment areused to tarnsform original data in order to reflect performances by the non texas banks with respect to risk coverage as well as efficiency formulas for transforming to and from the original data are supplied with accompanying explanations and interpretations which include comparisons with the risk adjusted capital and risk coverage allowances formulas that have been adopted recently by u s government and other regulators in banking and insurance in conformance with the basel agreement of 1988

cost efficiency and scale economies in the turkish insurance industry this article examines the cost efficiency and scale economies of insurance firms in the turkish insurance industry over a 15 year period 1990 2004 using the stochastic cost frontier model cost efficiency scores and scale economies were estimated for each firm in the sample the results show that mean cost inefficiencies range between 18 3 and 36 9 of total costs and they do not tend to decrease over time on average small firms are more cost efficient than large firms economies of scale appear present and significant for any class size the results suggest that there is a substantial difference in scale economies between small and large insurance firms

why some jobs command wage premiums a test of career tournament and internal labor market hypotheses the wage premiums associated with jobs in a large organization were identified through comparing their pay to the prevailing wages in the relevant outside labor markets we then examined the characteristics of those jobs to investigate why some commanded larger premiums than others jobs at the tops of promotion ladders jobs requiring many organization specific skills and to a lesser extent jobs with access to influence commanded greater wage premiums wages above market rates appear important in supporting the internal labor market mechanisms associated with these jobs findings may clarify the factors compensation managers should consider when positioning wage rates examination of these issues is a potentially important bridge between the study of internal labor markets in organizational research and the study of wages in economics

an examination of cost subadditivity and multiproduct production in large u s banks this paper examines the subadditivity of costs for a sample of the largest commercial banks in the u s we introduce into the bank production literature the grid approach developed by evans and heckman 1984 we estimate two models of the bank cost function one where deposits are treated as outputs while in the other deposits are treated as inputs the models are estimated using the commonly used translog and the more flexible miniflex laurent viewed narrowly the findings imply that cost complementarities are not the raison d etre for multiproduct production in the largest commercial banks subadditive costs however are sufficient but not necessary for multiproduct production it is quite possible for multiproduct production to be optimal when output are produced independently levy and haber 1986 and teece 1980 1982 it is only required that inputs be shareable as opposed to joint copyright 1990 by ohio state university press

endogenous bank risk and efficiency we develop a framework to incorporate bank risk as measured from the variance of profits or returns within a model of frontier efficiency our framework follows the premise that risk is endogenously related to efficiency we estimate our model using panel data for u s banks and bayesian techniques we show that excluding risk from the efficiency model significantly biases the efficiency estimates and the ranking of banks according to their competitive advantage we also demonstrate that there is a negative risk efficiency nexus with causality running both ways while our estimates of risk are fully consistent with the developments in the banking industry over the period 1976 2014

a comprehensive analysis of the effects of risk measures on bank efficiency evidence from emerging asian countries this study investigates the role of risk in determining the cost efficiency of international banks in eight emerging asian countries researchers of this paper consider three distinct risk aspects under a total of eight risk measures credit risk operational risk and market risk we apply a heteroscedastic stochastic frontier model to estimate bank cost efficiency in our analysis additionally this study analyzes the marginal effects of all risk measures on the inefficiency effect in order to explore a more detailed relationship between risks and efficiency the empirical results indicate that the risk measures represent significant effects on both the level and variability of bank efficiency we also find that these effects vary across countries and over time

understanding organizational wage structures a resource dependence approach data on the salaries for high level administrative positions in 608 colleges and universities were used to examine the relative salaries for six positions controlling for other factors we found t

preemptive patenting and the persistence of monopoly this article takes a different tack and inquires whether institutions such as the patent system create opportunities for firms with monopoly power to maintain their monopoly power the results apply to other situations such as brand identification spatial location and capacity expansion which share the characteristic that early or preemptive actions may lower the returns to potential competitors

efficiency in the savings and loan industry abstract the stochastic econometric cost frontier approach is modified to investigate efficiency in mutual and stock s ls using 1991 data on u s s ls this methodology allows both the cost frontier and error structures to differ between s ls of these two ownership forms a likelihood ratio test indicates that the data support this unrestricted model which implies efficient mutual and stock s ls use different production technologies various measures of inefficiency show that on average stock s ls are less efficient than mutual s ls the second part of the article relates the inefficiency measures to several correlates

mergers and technical efficiency in spanish savings banks a stochastic distance function approach abstract the aim of this paper is to test the temporal variation of technical efficiency of spanish savings banks during the period 1985 1998 furthermore we test whether merged and non merged firms have different levels and temporal patterns of technical efficiency a stochastic output distance function r w shephard theory of cost and production functions princeton university press princeton nj is employed to accommodate multiple output technology the distance function provides the advantage that it does not need information about prices so it can accommodate the multi product nature of the financial sector only using the quantities as data an important point when the assumptions about perfectly competitive markets are unlikely to be met the temporal variation of efficiency is modeled extending the battese and coelli journal of productivity analysis 3 1992 153 169 approach in two ways relaxing the monotonicity of the temporal variation pattern of the efficiency term and allowing for different patterns of efficiency change between merged and non merged firms

the patent paradox revisited an empirical study of patenting in the u s semiconductor industry 1979 1995 we examine the patenting behavior of firms in an industry characterized by rapid technological change and cumulative innovation recent survey evidence suggests that semiconductor firms do not rely heavily on patents to appropriate returns to r d yet the propensity of semiconductor firms to patent has risen dramatically since the mid1980s we explore this apparent paradox by conducting interviews with industry representatives and analyzing the patenting behavior of 95 u s semiconductor firms during 1979 1995 the results suggest that the 1980s strengthening of u s patent rights spawned patent portfolio races among capital intensive firms but it also facilitated entry by specialized design firms

an examination on the cost efficiency of the banking industry under multiple output prices uncertainty this article formulates a behavioural model of profit maximization which explicitly incorporates both multiple output prices risk and safety first practice this theoretical model is specifically suitable for investigating financial institutions whose output prices frequently encounter a variety of risks such as loan defaults arrears the sample banks are empirically found to be highly risk averse furthermore risk preferences exert little effect on the technical efficiency estimates whereas the same estimates obtained by the standard fixed effect model under certainty tend to be overestimated evidence is found that a specialized bank offering a single product with a larger scale of production will be preferable in an uncertain atmosphere

cross country comparisons of efficiency evidence from the uk and italian investment firms abstract this paper compares and reconciles two new methods for cross country comparisons of the cost efficiency of uk and italian investment firms over the period 1995 1998 it employs four different specifications of the stochastic frontier methodology using a translog cost function in order to measure x efficiency the traditional common frontier reveals that italian investment firms are nearly as efficient as uk firms to overcome traditional limitations two methods are used in this paper they provide consistent results the first method shows differences between the efficiency of the two countries by incorporating environmental variables into the cross country common frontier the second method shows differences in the efficiency of the domestic versus foreign investment firms in the two countries by testing the ability to monitor and control on a cross border basis finally to identify investment firms that are both cost and profit efficient we undertake a profitability test

disparities in the financial performance of agricultural entities according to the legal form the case of slovakia abstractfinancial management in agricultural enterprises is affected by a range of factors that are not present in other sectors one of the factors that affect the performance of enterprises is th

a fourier analysis of the us dairy industry measurement of economies of scale and scope is particularly important for predicting growth and product diversification however estimates are useful only to the extent the underlying production technology is modelled accurately this study measures economies of scale and scope in the rapidly changing us dairy industry with a fourier flexible cost function which provides a global approximation of the unknown function we use the high quality national agricultural and resource management survey arms survey data we find economies of scale at most firm sizes and persistent economies of scope across firm sizes in this industry which is counter to estimates from two diewert flexible functional forms

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

how broad should the scope of patent protection be i explore the trade off between a patent s length that is its lifetime and its width that is its scope of coverage a wider patent generally reduces the distortion of consumers choices between the patented brand of the product and unpatented lower priced varieties sold by competitors but also permits higher prices which increase relative to profits the deadweight losses from consumers switching consumption out of the product class i show under what conditions infinitely lived but very narrowly focused patents are the socially efficient way to reward innovation and under what conditions very short lived but very broad patents are optimal

is there a single frontier in a single european banking market abstract this paper attempts to estimate comparable efficiency scores for european banks operating in the single market in the eu using a data set of more than 5000 large commercial banks from all major european banking markets over the period 1993 2004 the application of meta frontiers enables us to assess the existence of a single and integrated european banking market we find evidence in favor of a single european banking market characterized by cost and profit meta frontiers however compared to the meta frontier estimations pooled frontier estimations tend to underestimate efficiency levels and correlate poorly with country specific frontier efficiency ranks

incorporating risk input into the analysis of bank productivity application to the taiwanese banking industry abstract this study reappraises banks productivity by using 42 taiwanese banks during 1999 2007 as observations it introduces an input oriented generalized metafrontier malmquist productivity index i gmmpi while considering the latent effect of risk taking behavior in the analytic framework we learn that public and private banks should face separate short term technological frontiers while the econometric model considering risk input can portray banks operating frontiers better moreover neglecting the influence of risk input would bring about distortions of efficiency technology and tfp dynamic estimations for banks meanwhile the degree of scale economies would also be overestimated the paper concludes that neglecting the risk taking essence in bank performance evaluation is equal to allowing banks to barter risk bearing as the term for further output growth consequently the potential cost is that banks may excessively aggrandize their scales of business implying the possibility of another financial crisis

pesticide use environmental spillovers and efficiency a dea risk adjusted efficiency approach applied to dutch arable farming pesticides are widely used by crop producers in developed countries to combat risk associated with pests and diseases however their indiscriminate use can lead to various environmental spillovers that may alter the agricultural production environment thus contributing to production risk this study utilises a data envelopment analysis dea approach to measure performance of arable farms incorporating pesticides environmental spillovers and output variance as undesirable outputs in the efficiency analysis and taking explicitly into account the effect of pesticides and other inputs on production risk the application focuses on panel data from dutch arable farms over the period 2003 2007 a moment approach is used to compute output variance providing empirical representations of the risk increasing or decreasing nature of the used inputs finally shadow values of risk adjusted inputs are computed we find that pesticides are overused in dutch arable farming and there is a considerable evidence of the need for decreasing pesticides environmental spillovers

patent litigation as an information transmission mechanism patent litigation reveals important information about the validity of the contested patent to other potential entrants this paper explores the implications of such informational externalities for entry dynamics in the presence of multiple potential entrants the nature of the entry game can be one of either waiting or preemption depending on the degree of patent protection therefore the payoffs for the patentee and the initial imitator are discontinuous in the degree of patent protection furthermore strengthening intellectual property rights is not necessarily desirable for the patentee the analysis may also help explain the apparently puzzling practice of delaying patent suits copyright 1998 by american economic association

internal labor markets firm specific human capital and heterogeneity antecedents of employee idiosyncratic deal requests a field study of 615 managers in 11 korean manufacturing firms extends theory regarding labor contracting to the study of idiosyncratic deals i deals despite i deals potential to benefit both employees and employers economic theory asserts that employers attempt to reduce individual contracting by use of internal labor markets ilms this study identifies limits to that assertion by identifying conditions under which i deals are sought despite employee participation in ilms furthermore we develop and test theory reconciling the roles of ilms and firm specific human capital in employee requests for i deals employee reports of ilm practices are negatively related to i deal requests whereas firm specific human capital is positively related to these requests in addition we find an interaction between the two such that the suppressive effects of ilm reports on i deal requests hold largely for workers with low firm specific human capital individuals with high firm specific human capital tend to seek i deals despite reported ilm practices i deal requests also increase with group level heterogeneity in firm specific human capital in all our findings suggest that ilms function as economic theory asserts for workers with limited firm specific human capital but they are less able to reduce i deal requests among workers with higher firm specific human capital

how do banks adjust to changing input prices a dynamic analysis of u s commercial banks before and after the crisis abstract the 2000 2013 period was characterized by substantial regulatory monetary and technological change especially after the onset of the global financial crisis this study assesses the total impact of these policy shifts and technological changes on u s commercial banks short run and long run substitution elasticities an endogenous break test divides the sample into a pre crisis period and a post crisis period during the former period banks inputs tend to be inelastic substitutes after the onset of the crisis particularly the long run substitutability of most input factors decreases to even lower levels due to changes in both cost technology and economic conditions at the same time banks response to input price changes becomes more sluggish hence especially after the onset of the crisis banks have little flexibility regarding input factor usage and are thus sensitive to input price changes from a cost perspective

operational efficiency in banking an international comparison reply to the comment abstract to avoid problems associated with jensen s inequality we use a corrected inefficiency measure to compare the estimate of inefficiency obtained using the distribution free df method with the estimate obtained using the stochastic cost frontier scf the results of the paper are unchanged the df method yields measures of inefficiency that are significantly higher than measures obtained using the scf
