comparing the performance of health care systems an alternative approach the health care system in the united states has been diagnosed as a moribund institution by a large number of media commentators and health policy analysts continually rising health care costs and inadequate health insurance coverage for approximately thirty seven million people are cited as two of the most visible symptoms supporting their diagnosis most of these individuals see little chance for the u s health care system to recover given its present design full recovery they believe requires the successful transplant of a health care system from another country the health care systems in europe and canada where government is assigned a much larger role than in the united states are argued to offer universal health care coverage and simultaneously contain health care costs simple comparative statistics appear to support the view that the performance of the u s health care system could be improved through a new health care system design infant mortality in the united states ranked twentieth among twenty four member countries of the organization for economic cooperation and development oecd in 1988 yet health care expenditures in the united states comprised 11 8 percent of gross domestic product in 1989 while the comparable average for all oecd countries was only 7 4 percent 28 these statistics portray the u s health care system as being deficient and therefore unable to offer quality medical services at a reasonable price given the limited stock of information that exists on this issue however it is ill advised to place full blame for the seemingly dismal performance on the u s health care system the simple international comparisons fail to take into account that differences in performance are not solely due to variations in health care systems while the design of a health care system including the financing scheme reimbursement method and organization of production is indeed important because it influences how various economic technological and demographic characteristics of a country are transformed into health outcomes the performance of the health care system also depends on the magnitude of these national characteristics as well a proper analysis would try to determine how the health care system itself specifically influences the performance of health

banking technology and the existence of a consistent output aggregate abstract this paper addresses the question of the existence of a consistent output aggregate in banking specific necessary and sufficient conditions for output aggregation are developed and tested in the context of a second order approximation to any arbitrary multi product bank cost function the analysis provides evidence that a composite aggregate measure of output fails to provide a proper representation of banking technology and therefore previous studies that used aggregate output measures may well be subject to specification errors

efficiency analysis in banking firms an international comparison abstract the intensive process of financial european integration together with the profound transformation and deregulation that has taken place in the spanish banking system justifies the evaluation of its efficiency in comparison with that of other banking systems in this context the aim of this study is to analyze the productivity efficiency and differences in technology of several banking systems using a non parametric approach together with the malmquist index we compare the efficiency productivity and differences in technology of different european and us banking systems for the year 1992

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

a performance assessment of mozambique banks a bayesian stochastic frontier abstractthis article analyses the technical efficiency of mozambican banks from 2005 to 2014 with a bayesian stochastic frontier model the intermediate approach is adopted and the results reveal that efficiency varies amongst the banks analysed foreign ownership of mozambican banks is also analysed as is public ownership the role of mergers and acquisitions big banks and active dividend policy within the context of bank costs policy implications are then derived

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

a hedonic analysis of rent and rental revenue in the subsidised and unsubsidised housing sectors in geneva in this paper an analysis is made of what would be the rent difference for the tenants of subsidised units if these units were rented as unsubsidised units furthermore the existence of any pecuniary disadvantage for the owner of a subsidised unit is investigated by considering his rental revenue i e the amount paid by the tenant and the subsidy it is found that there exists a premium between an unsubsidised and a subsidised unit when using the amount paid by the tenant i e the rent as the dependent variable also the subsidy system in geneva has an influence on the pricing of each characteristic of a unit furthermore it is found that when using rental revenue as the dependent variable both sub samples can be used in a single hedonic equation thus owners of subsidised units are not at a disadvantage due to the granting of a subsidy as a result geneva s subsidy system matches the goals of agents on both the demand and supply sides

poverty and growth impacts of high oil prices evidence from sri lanka the sharp rise in oil and food prices in 2007 and 2008 caused negative impacts on poverty and economic growth in many oil and food importing developing countries some analysts believe that these countries are under stress again due to a rise in crude oil prices to a two and a half year high in march 2011 which has also been partly responsible for higher food prices in recent months however there is a limited body of empirical evidence available from developing countries on the impact of high oil prices on growth in general and household poverty in particular in this study sri lanka is used as a case study and a computable general equilibrium cge approach is adopted as an analytical framework to explore the growth and poverty impacts of high oil prices the results suggest that urban low income households are the group most adversely affected by high global oil prices followed by low income rural households in contrast estate low income households are the least affected out of all low income households the energy intensive manufacturing sector and services sector are affected most compared to the agricultural sector

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

methods for including income distribution in global cge models for long term climate change research abstract the consequences of climate policy and the impacts of climate change vary among different types of households depending on their income level expenditure pattern and other socioeconomic characteristics global economy environment models that are used to assess climate change issues traditionally do not distinguish households by income or other attributes to facilitate progress in this area we review and assess literature on methods to include household heterogeneity in global long term computable general equilibrium cge models we distinguish among three categories of approaches 1 the explicit modeling of multiple household types within the cge framework 2 micro simulation modeling and 3 direct modeling of income distribution for each of these approaches we describe the method key assumptions limitations and several prominent examples from the literature moreover we discuss data needs including the contents of household survey data their availability and processing we conclude with an overview of what each method could provide for global long term climate related research

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

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

financial distress drivers in brazilian banks a dynamic slacks approach abstract this study applies the dynamic slacks based model dsbm developed by tone and tsutsui 2010 in order to assess the evolution of input saving output increasing potentials in major brazilian banks from 1996 to 2011 we propose that these potentials or slacks can be used as proxies for an eventual financial distress situation in the future the main research objective is to determine whether or not different characteristics of bank type related to ownership size and merger and acquisition processes are significantly related to inefficiency levels and by extension to an eventual financial distress situation since higher inefficiency levels also imply lower input saving output decreasing potentials based on a balanced panel model secondary data from economatica were collected and analyzed results indicate higher inefficiency levels and slacks in small public and national banks policy implications are also addressed

energy and ghg emission efficiency in the chilean manufacturing industry sectoral and regional analysis by dea and malmquist indexes abstract global warming produced mainly by the emission of greenhouse gases is currently a worldwide concern in the last few decades since the 1950s many of the changes observed in the world climate have been meaningful this paper presents an analysis of energy efficiency and of greenhouse gas emissions in the chilean manufacturing industry by region and sector taking into consideration time sequences data envelopment analysis dea models are used for the analysis three ways to handle undesirable outputs are compared the source of inefficiency in each decision making unit dmu is calculated using scale efficiency and the evolution over time is analyzed using the malmquist index the results indicate that the industries located in the chilean regions of coquimbo la araucania and aysen were the most efficient while the industries in the regions of tarapaca antofagasta and biobio were less efficient the most efficient industrial sectors were those involving communications equipment base metals and clothing the least efficient were those concerned with food and beverages textiles and nonmetallic minerals due to the treatment of the undesirable outputs differences were found in the efficiency indexes obtained by the three models this finding suggests using a model better adapted to the characteristics of the outputs in question and the viability of improving industrial practices

dynamic effects in inefficiency evidence from the colombian banking sector firms face a continuous process of technological and environmental changes that requires them to make managerial decisions in a dynamic context however costs and constraints prevent firms from making instant adjustments towards optimal conditions and may cause inefficiency to persist in time we propose a dynamic inefficiency specification that captures differences in the adjustment costs among firms and non persistent effects of inefficiency heterogeneity the model is fitted to a ten year sample of colombian banks the new specification improves model fit and have effects on efficiency estimations overall colombian banks present high inefficiency persistence but important differences between institutions are found in particular merged banks present low adjustment costs that allow them to recover rapidly efficiency losses derived from merging processes

computable general equilibrium models for development policy analysis in ldcs abstract the use of cge models has gained much popularity among policy analysts in ldcs and there is a fast growing body of literature on this area of economics in this survey the advantages of general equilibrium approach over partial equilibrium approach in analysing a wide range of policy issues are highlighted the evolution of cge modelling is discussed and more than 60 cge applications related to different policy issues in ldcs are surveyed this comprehensive survey shows that the cge models have become quite popular analytical tools among policy analysts in ldcs over the last decade or so the debate in the economic profession regarding the value and appropriateness of using cge models for policy analysis is examined in the final section of this paper some of the criticisms levelled at cge models are discussed and it is argued that despite this criticism such models are capable of providing insight into important policy problems

the technical efficiency of us banks abstract the paper uses a non parametric frontier approach to measure the technical efficiency of a sample of u s banks the results indicate that these banks could have produced the same level of output with only 70 of the inputs actually used in addition most of this inefficiency is due to pure technical inefficiency wasting inputs rather than scale inefficiency operating at non constant returns to scale finally regression analysis indicates that the technical efficiency of the banks is positively related to size negatively related to product diversity and not at all related to the extent to which branch banking is allowed

managers and efficiency in banking abstract this paper presents evidence on the impact of managers on cost efficiency in banking stochastic frontier analysis is applied to a unique finnish data set manager age and education have strong yet complicated effects on efficiency the impact of age on efficiency depends on education a university degree is useful mainly in the largest banks of the sample educational background seems to be less important for young managers than for mature ones managing director changes are systematically followed by efficiency changes retirement typically causes an efficiency improvement whereas other manager changes can either improve or weaken efficiency however in many cases mature managers outperform their young colleagues

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

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

the specification of hedonic indexes for urban housing most studies evaluating the effect on housing prices of regulatory programs for controlling urban growth use econometric methods hedonic price models without considering the research design aspects of the task this article examines the strengths and

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

price effects of rent control on controlled and uncontrolled rental housing in toronto a hedonic index approach this paper examines the price effects of rent controls with exemptions on rent controlled and non rent controlled housing in toronto a model of rent determination in the controlled and uncontrolled markets is presented the paper then applies a hedonic pricing technique to develop indices of the uncontrolled rent relative to the controlled rent for standardized sets of housing characteristics approximately one half of the difference in observed rents is attributable to quality differences between markets and one half to the effect of rent controls

assessing productive efficiency of banks using integrated fuzzy dea and bootstrapping a case of mozambican banks performance analysis has become a vital part of the management practices in the banking industry there are numerous applications using dea models to estimate efficiency in banking and most of them assume that inputs and outputs are known with absolute precision here we propose new fuzzy dea level models to assess underlying uncertainty further bootstrap truncated regressions with fixed factors are used to measure the impact of each model on the efficiency scores and to identify the most relevant contextual variables on efficiency the proposed models have been demonstrated using an application in mozambican banks to handle the underlying uncertainty findings reveal that fuzziness is predominant over randomness in interpreting the results in addition fuzziness can be used by decision makers to identify missing variables to help in interpreting the results price of labor price of capital and market share were found to be the significant factors in measuring bank efficiency managerial implications are addressed

total factor productivity growth technological progress and technical efficiency change dimensions of productivity change in yugoslavia 1965 1978 this article total factor productivity growth technological progress and technical efficiency change dimensions of productivity change in yugoslavia 1965 78 was reprinted with permission from the december 1982 issue of the economic journal this article proposes a methodology that decomposes total factor productivity change into two distinct elements technological progress and changes in technical efficiency technological progress is defined as the change in the best practice production frontier all other productivity change is attributed to technical efficiency change the article provides a theoretical framework for decomposing total factor productivity growth as well as a specification and estimation of the deterministic frontier production function it employs a programming technique to estimate a flexible functional form of the production frontier the paper then applies this technique to empirical data from yugoslavia of the period from 1965 to 1978 it concludes that for yugoslavia improvements to technical efficiency comprise the dominant contribution to total factor productivity change this agrees with accumulating evidence that in many developing economies productivity gain due to technological mastery of imported technology is substantial

time for revisionism on rent control economists traditional hostility to rent contols is based on models that treat the housing market as perfectly competitive and on the experience with hard controls in new york city and many european countries following world war ii the current soft rent control systems in north america are varied and qualitatively different from earlier hard controls the theoretical case against them is weak particularly when the housing market is viewed as imperfectly competitive the empirical case against them is weak too economists should reconsider their blanket opposition to current rent control systems and evaluate them on a case by case basis

evaluating the role of subsidy reform in addressing poverty levels in malaysia a cge poverty framework abstractmalaysia as one of the top subsidised countries around the world has launched to reduce subsidies to capture its development goals this study therefore analyses the effects of the subsidy reform on the macroeconomic welfare and poverty levels of malaysia by applying a cge model the findings suggest that subsidy removal leads to significant falls in both income and consumption of rural urban and non citizen households and consequently decreases their welfare however poverty levels among rural households will most likely increase significantly when compared to urban households due to their relatively low level of income compared to other groups

technical scale and allocative efficiencies in u s banking an empirical investigation a nonparametric frontier approach is used to calculate the overall technical pure technical allocative and scale efficiencies for a sample of 322 independent banks the sample was drawn from the federal deposit insurance corporation tapes on the reports of condition and reports of income call reports for the year 1986 the results indicated a low level of overall efficiency the main source of inefficiency was technical in nature rather than allocative separate efficiency frontiers were constructed to test the effect of branching however the distributions of efficiency measures for branching and non branching banks were not found to be different

multidirectional conditional convergence in european banking abstract the paper examines the behavioural patterns arising from the analysis of productivity and convergence in european banking using a sample of commercial banks regulated by the single supervisory mechanism during 2011 to 2017 productivity change and its decompositions is measured for each input and output dimension separately using a variant of the multidirectional productivity analysis framework we introduce a novel approach for testing for convergence in productivity efficiency and technology as well as in each dimension considered we find strong evidence of absolute convergence during the period of study suggesting that bank operations move towards a common frontier rather than local equilibria prior to the creation of the single supervisory mechanism in 2013 conditional convergence is confirmed in many instances with respect to liquidity and capital adequacy although few cases remain significant in the subsequent period we conclude that regulatory controls have facilitated integration though there are important implications arising that policymakers need to consider when designing policies

a note on efficiency and productivity growth in the korean banking industry 1992 2002 abstract in this paper we present estimates of korean bank inefficiency and productivity change for the period 1992 2002 that are derived from the directional technology distance function our method controls for loan losses that are an undesirable by product arising from the production of loans and allows the aggregation of individual bank inefficiency and productivity growth to the industry level our findings indicate that technical progress during the period was more than enough to offset efficiency declines so that the banking industry experienced productivity growth

risks and financing decisions in the energy sector an empirical investigation using firm level data using a sample of 102 uk energy firms over the period 1981 2009 this paper empirically examines the effects of uncertainty on firms leverage decisions the results indicate that both firms specific and macroeconomic uncertainty have negative sizeable and statistically significant impacts on the uk energy sector firms target leverage the results also indicate that the profitability of energy firms plays an important role in uncertainty leverage relationship by changing the total effect of uncertainty on leverage while more profitable firms appear to reduce their leverage by a relatively large amount in response to increased macroeconomic uncertainty they are less likely to be affected by firm specific uncertainty these results suggest that stability in macroeconomic conditions and business activity is important to the stability of the capital structure of firms in the energy sector which would in turn be conducive to stability in their investments and production

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

do cross country differences in bank efficiency support a policy of national champions abstract as banking consolidation proceeds and europe moves toward a single market cross country differences in banking efficiency can affect the future competitive position of a country s financial market helping to determine which european money centers may expand or contract looking at large banks across 10 countries we find they are roughly equally efficient after controlling for differences in business environment banking costs and bank productivity as no country seems to have a strong efficiency advantage it seems likely that state efforts to promote national champions through favorable mergers which expand scale and market share may determine the outcome

rationality of energy efficiency improvement targets under the pat scheme in india a case of thermal power plants abstract the market based perform achieve and trade scheme was introduced in india to enhance the energy efficiency of energy intensive sectors and for thermal power plants by reducing their specific energy consumption within the framework of a tradable certificate scheme international experience suggests that effectiveness of such schemes is greatly influenced by the assigned targets of the obligated units setting rational targets is thus a key aspect of successful implementation of the scheme in the present study we examine the rationality of the targets set for the power sector of india based on comparing it with energy saving potential of the plants and the targets assigned to the respective plants data envelopment analysis models are used to determine relative efficiency and energy saving potential the study results indicate that in most cases i the targets are much less than the actual potentials of the thermal power sector ii there exist substantial inefficiencies within the system in both energy use and managerial dexterity and iii if the sector realizes its full potential then the energy saving certificate market may witness a surplus of 4 7 million certificates on account of thermal power sector alone

assessing eco efficiency through the dea analysis and decoupling index in the latin america countries abstract this study was developed according to a two step approach in the first step we provide an investigation of the changes in eco efficiency under constant and variable return to scale while on a second step the evaluation of the decoupling elasticity will be given the impacts of energy economic and environmental determinants inputs on the performance indicators of eco efficiency were calculated as the inverse of the carbon intensity ratio of the gdp over the co2 emissions both from the world development indicators database the changes in eco efficiency and the decoupling elasticity between co2 emissions and economic growth changes data was used for 16 latin america countries according to five year periods from 1994 to 2013 for all the five time span considered it is worth noting that the degree of technical efficiency for the latin america countries is lower than the degree of technological efficiency thus indicating that a portion of the overall inefficiency is due to the fact that these countries are producing below the production frontier rather than to an inefficient use of technology on average the results have confirmed that the technological scale change in energy production is the dominant factor influencing the optimal production frontier in the sample of countries under analysis complementarily according to the mixed results from the decoupling analysis we may conclude that the increase decrease of the co2 per capita emissions was due to other economic and environmental factors rather than to a negative positive effect of the gdp growth rate

banks efficiency and credit risk analysis using by production approach the case of iranian banks abstractthis article uses a by production approach that integrates credit risk to monitor bank efficiency the method overcomes the possible misspecification issues of the commonly assumed weak disposability wda of undesirable outputs in addition our measure extends the classic by production approach by including statistical aspects through subsampling techniques we have also provided an algorithm to correct related infeasibilities using this approach we investigate the performance of iranian banks and credit risk management in the sector for the period 1998 2012 non performing loans npls have been used as an undesirable output and proxy for credit risk in our models based on our empirical results although the banks generally exhibited efficiency improvements over time their credit risk performance deteriorated considerably after the regulatory changes introduced in 2005 these findings confirm that credit quality can be monitored more actively across iranian banks

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

the effects of deregulation on the performance of financial institutions the case of spanish savings banks this paper examines the impact of regulatory reform on the performance of spanish savings banks the focus is whether increased competition brought on by deregulation affected performance of banks over time output technical efficiency which is defined in terms of the production possibility frontier is also examined empirical results show declining levels of output technical efficiency along with a significantly high rate of technical progress in spite of declining technical efficiency during this period evidence of an increasing trend in productivity growth is found

sex differentials in unemployment rates a case for no concern this paper reevaluates the concept of unemployment in the context of differing labor market and nonmarket opportunities for men and women discussing common fallacies in female to male unemployment rate comparisons and their use as an indicator of labor market equality suggestive empirical evidence is presented for an alternative unemployment rate concept for women for interpreting the procyclical variation in female to male unemployment rate differentials and for decomposing unemployment differences into differences in labor market characteristics and in behavioral coefficients for the two sexes the paper concludes that a large part of the observed unemployment rate differential may be attributed to the definition and methodology used in deriving unemployment statistics rather than to discrimination in productive opportunities

malmquist type indices in the presence of negative data an application to bank branches in this paper we develop an index and an indicator of productivity change that can be used with negative data for that purpose the range directional model rdm a particular case of the directional distance function is used for computing efficiency in the presence of negative data we use rdm efficiency measures to arrive at a malmquist type index which can reflect productivity change and we use rdm inefficiency measures to arrive at a luenberger productivity indicator and relate the two the productivity index and indicator are developed relative to a fixed meta technology and so they are referred to as a meta malmquist index and meta luenberger indicator we also address the fact that vrs technologies are used for computing the productivity index and indicator a requirement under negative data which raises issues relating to the interpretability of the index we illustrate how the meta malmquist index can be used not only for comparing the performance of a unit in two time periods but also for comparing the performance of two different units at the same or different time periods the proposed approach is then applied to a sample of bank branches where negative data were involved the paper shows how the approach yields information from a variety of perspectives on performance which management can use

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

aggregate poverty measures the way poverty is measured is important for an understanding of what has happened to poverty as well as for anti poverty policy evaluation sen s 1976 pathfinding work has motivated many researchers to focus on the way poverty should be measured a poverty measure argued by sen should satisfy certain properties or axioms and the desirability of a poverty measure should be evaluated by these axioms during the last two decades many researchers have adopted the axiomatic approach pioneered by sen to propose additional axioms and develop alternative poverty measures the objective of this survey is to provide a clarification on the extensive literature of aggregate poverty measures in this survey we first examine the desirability of each axiom the properties of each poverty measure and the interrelationships among axioms the desirability of an axiom cannot be evaluated in isolation and some combination of axioms may make it impossible to devise a satisfactory poverty measure some axioms can be implied by other axioms combined and so are not independent some others are ad hoc and are disqualified as axioms for poverty measurement based on the interactions among axioms we identify the core axioms which together have a strong implication on the functional form of a poverty measure we then review poverty measures that have appeared in the literature evaluating the interrelationships among different measures and examining the properties of each measure the axioms each measure satisfies violates are also summarized in a tabular form several good poverty measures which have not been documented by previous surveys are also included

oil prices and the south african economy a macro meso micro analysis abstract three levels of analysis are used to track the channels by which south africa and its people are impacted by an increase of oil prices namely the macro economic level the meso economic level and the micro economic household level the paper uses an economy and energy integrated approach to quantify these different channels the approach combines a household survey dataset and an input output dataset to implement the models results indicate that the impacts on the macroeconomy are negative with gross domestic product falling and the current account balance worsening all of the industries falling into the high intensive oil use group witness an increase of their input cost that is above the economy wide average the impact of doubling paraffin prices results in poor households in rural areas and among the black population in particular witnessing an increase of their cost of living which is much higher than their corresponding highest expenditure quintile groups an increase of transport fuel hits the richer households much harder the distributional impacts of rising transport cost as a consequence of high oil and oil products prices shows that median quintile expenditure groups observe the highest impact both in urban and rural areas and especially among the black population

financial deregulation and total factor productivity change an empirical study of turkish commercial banks abstract in january 1980 a new liberal economic policy was adopted in turkey to promote financial market development and increase the efficiency and productivity of the financial sector by fostering competition among banks as a result of this policy the turkish banking system witnessed a series of legal structural and institutional changes throughout the 1980s to enhance their competitive viability turkish banks responded by streamlining their operations and investing in new technology utilizing a dea type malmquist total factor productivity change index we examine productivity growth efficiency change and technical progress in turkish commercial banks during the deregulation of financial markets in turkey we found that all forms of turkish banks although in different magnitudes have recorded significant productivity gains driven mostly by efficiency increases rather than technical progress efficiency increases however were mostly owing to improved resource management practices rather than improved scales our results also indicate that private banks began to close their performance gap with public banks in the new environment

the joint estimation of bank level market power and efficiency the aim of this study is to provide a methodology for the joint estimation of efficiency and market power of individual banks the proposed method utilizes the separate implications of the new empirical industrial organization and the stochastic frontier literatures and suggests identification using the local maximum likelihood lml technique through lml estimation of market power of individual banks becomes feasible while a number of restrictive theoretical and empirical assumptions are relaxed the empirical analysis is carried out on the basis of emu bank data market power estimates indicate fairly competitive conduct in general however heterogeneity in market power estimates is substantial across banks the latter result suggests that the practice of some banks deviates from the average fairly competitive behavior a finding that has important policy implications finally efficiency and market power present a negative relationship which is in line with the so called quiet life hypothesis

efficiency technical change and returns to scale in large us banks panel data evidence from an output distance function satisfying theoretical regularity abstract this paper provides parametric estimates of technical change efficiency change economies of scale and total factor productivity growth for large banks those with assets in excess of 1 billion in the united states over the period from 2000 to 2005 this is done by estimating an output distance function subject to theoretical regularity within a bayesian framework we find that failure to incorporate theoretical regularity conditions results in mismeasured shadow revenue and or cost shares which in turn leads to perverse conclusions regarding productivity growth our results from the regularity constrained model show that total factor productivity of the large us banks grew at an average rate of 1 98 over the sample period however our estimates also show a clear downward trend in the growth rate of total factor productivity and our decomposition of the primal divisia total factor productivity growth index into its three components technical change efficiency change and economies of scale indicates that technical change is the driving force behind this decline

the effect of rent control on the price of rental housing an hedonic approach it is widely believed that rent control leads to a decline in the quality of rental housing this study examines the effect of rent control on the quality of rental housing in new york city quality change is linked to the suppression of rent below
