can falling supply explain the rising return to college for younger men a cohort based analysis although the college high school wage gap for younger u s men has doubled over the past 30 years the gap for older men has remained nearly constant in the united kingdom and canada the college high school wage gap also increased for younger relative to older men using a model with imperfect substitution between similarly educated workers in different age groups we argue that these shifts reflect changes in the relative supply of highly educated workers across age groups the driving force behind these changes is the slowdown in the rate of growth of educational attainment that began with cohorts born in the early 1950s in all three countries

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

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

social class family background and intergenerational mobility abstract this research examines the various approaches taken by economists and sociologists for analyzing intergenerational mobility social mobility models based on social classes arising from an occupational classification scheme are analysed a test for the statistical validity of classification schemes is proposed and tested using danish sample survey data that was first collected in 1976 and augmented in 2000 this is referred to as a homogeneity test and is a likelihood ratio test of a set of linear restrictions which define social classes for denmark it is shown that this test fails for an erikson goldthorpe classification system raising doubts about the statistical validity of occupational classification systems in general we also estimate regression models of occupational earnings household earnings and educational attainment using family background variables as covariates controlling for unobservables measurement error and simultaneous equation bias in these models homogeneity tests are also rejected we conclude from these results that the individual s family background has a small but significant impact on lifetime chances which is not captured by the erikson goldthorpe classification scheme

an index number approach to measuring bank efficiency an application to mergers abstract the current wave of bank mergers has resulted in an interest in the measurement of consequent efficiencies previous studies have generally focused on the measurement of merger induced cost efficiencies in this paper we turn to the production side and examine the change in relative productivity arising from bank mergers after deriving our superlative multilateral productivity index we compute the indexes for our entire sample of banks approximately 2 000 banks in each of the years 1984 1988 and for a cohort of 160 banks that merged in 1986 we find that acquiring banks achieve no gains in efficiency and this finding supports those of other studies on the other hand we find that our acquiring banks are consistently more productive than the sample as a whole by implication if mergers can be generally characterized as the acquisition by a relatively more productive bank of a relatively less productive bank an empirically valid supposition then industry performance should improve as a result of these mergers

bias in malmquist index and cost function productivity measurement in banking this paper illustrates how many prior studies ofproductivity growth in the banking industry have been overstated this occurs with both dea malmquist index and parametric stochastic cost frontier productivity measurement approaches the problem is not due to the technique used but in how it is applied it is easiest to see in the banking industry due the nature ofthe data available the bias is eliminated when all outputs and inputs are included in the analysis ensuring that the balance sheet restriction is met although simple in concept this problem and its solution have so far been neglected in the literature r 2002 elsevier science b v all rights reserved

identifying determinants of branch performances in agricultural bank of china a spatial econometric approach this paper identifies determinants of branches performances in agricultural bank of china using the spatial econometric approach studies on changes of spatial patterns of a financial industry are scarce especially at the branch level this paper is the first attempt to take spatial interdependence and urbanisation effects into account to investigate the determinants of china s bank branches performances from 1997 to 2011 we have chosen the world s 10th largest bank the agricultural bank of china because it discloses the most complete panel data of all empirical evidence indicates that spatial effects and urbanisation have large statistically significant impacts on branches performances it highly and positively corresponds to tertiary industry output domestic consumption and urbanisation this signals that the abc has evolved from a state owned specialised bank to a listed commercial bank

hac estimation in spatial panels abstract we propose a hac estimator for the covariance matrix of the fixed effects estimator in a panel data model with unobserved fixed effects and errors that are both serially and spatially correlated

performance changes around bank mergers revenue enhancements versus cost reductions this paper examines operating performance around commercial bank mergers we find that industry adjusted operating performance of merged banks increases significantly after the merger large bank mergers produce greater performance gains than small bank mergers activity focusing mergers produce greater performance gains than activity diversifying mergers geographically focusing mergers produce greater performance gains than geographically diversifying mergers and performance gains are larger after the implementation of nationwide banking in 1997 further we find improved performance is the result of both revenue enhancements and cost reduction activities however revenue enhancements are most significant in those mergers that also experience reduced costs

changes in returns to education in latin america the role of demand and supply of skills using micro data for the urban areas of argentina brazil chile colombia and mexico the authors document trends in men s returns to education during the 1980s and the 1990s and estimate the role of supply and demand factors in explaining the changes in skill premia they propose a model of demand for skills with three production inputs corresponding to workers with primary secondary and university level education further the authors demonstrate that an unprecedented rise in the supply of workers having completed secondary level education depressed their wages relative to workers with primary level education throughout latin america this supply shift was compounded by a generalized shift in the demand for workers with tertiary education

dea and sfa research on the efficiency of microfinance institutions a meta analysis microfinance has played a key role in the fight against exclusion and the promotion of entrepreneurship in developing countries an important question today is how to increase the reach and profitability of microfinance in a context where subsidies are withdrawing to promote the viability and sustainability of microfinance institutions mfis efficiency analysis has found favor in this context and has attracted growing interest among professionals partners and researchers abundant empirical work has been conducted over the last ten years on this subject in very different contexts and with different methodologies the purpose of this article is to provide a meta regression analysis on parametric and nonparametric estimations of mean technical efficiency mte in microfinance using a data set of 262 observations from 38 studies the results show that in the microfinance industry mte scores have increased over time however with an mte rate of approximately 61 1 there is room for improving efficiency mfis use more resources than necessary for the results achieved in terms of outreach and revenue generated our results show heterogeneity of mte according to the methodological approach of the studies studies with a larger number of variables inputs and outputs produced higher mte scores than did those with a smaller number of variables studies using the variable returns to scale assumption resulted in higher mte scores than those using constant returns to scale in addition those with a production approach had higher mtes than did those using the intermediation approach while studies of a large number of mfis had lower scores than did those involving a small sample size moreover research estimating social efficiency generated lower mtes compared to those estimating financial efficiency studies using data from african mfis obtained lower mtes than did those on mfis in latin america and mena which confirms the poor performance of african microfinance

short run demand for palestinian labor palestinian residents of the west bank and gaza strip who work in israel generally earn more than palestinians employed locally but this wage premium is highly volatile beginning with the 1987 palestinian uprising changes in wage differentials by work location parallel palestinian absences from work in israel this article interprets changing location differentials in response to exogenous shocks as movements along an israeli demand curve for migrant workers estimates of a model of the west bank and gaza strip labor market are used to evaluate the effect of policies governing palestinian access to the israeli labor market

measuring heterogeneity in the returns to education using an education reform abstract in this paper we explore the impact of a mandatory education reform as well as pre reform availability of schools above the mandatory level on educational attainment and returns to education in norway we contribute to the existing literature by focusing on the heterogeneity of the impact of reforms our results indicate that increased compulsory education from seven to nine years increased the general level of education beyond the compulsory education we also find that the effect of family background on educational attainment was weaker after the reform the average treatment effect on returns to education is surprisingly high for education of intermediate duration this means that increasing the general level of education potentially generates high returns in the form of wages we also find that the effect of treatment on the treated on the returns to education is 1 4 percentage points higher than the average treatment effect

university library benchmarking an international comparison using dea abstract this paper proposes a framework for assessing the technical efficiency of 118 university libraries from australia austria canada germany switzerland and the united states the flexible non parametric approach of data envelopment analysis has been chosen to analyse the performance differentials of university libraries we also investigate whether the institutional settings affect the degree of library efficiency the findings of the intercountry efficiency comparison revealed that almost one third of the university libraries are technically efficient using environment specific frontiers to distinguish differences in managerial efficiency from differences in environmental efficiency we found considerable differences in technical efficiency between european and non european university libraries however as regards the environmental setting the non european best practice frontier outperforms the european best practice frontier

benefits to elite schools and the expected returns to education evidence from mexico city we exploit data on the future earnings students at high school completion expect to receive with and without a college education together with information on learning achievement and college outcomes to study the benefits from admission into a system of elite public high schools in mexico city using data for the centralized allocation of students into schools and an adapted regression discontinuity design strategy we estimate that elite school admission increases the future earnings and returns students expect from a college education these gains in earnings expectations seem to reflect improvement in actual earnings opportunities as admission to this elite school system also enhances learning achievement and college graduation outcomes this provides evidence of the earnings benefits from attending elite schools

industry performance and structural efficiency measures solutions to problems in firm models abstract it is shown that average unit structural efficiency measures do not measure the level of technical efficiency in a firm model of an industry alternative structural efficiency measures generalized to multiple input and multiple output technologies are presented as a solution to the problem of how to estimate the relative performance of an industry as a whole where reallocation of inputs across firms is not feasible compared to existing measures the proposed measures require additional information therefore the linear programming dea models needed to obtain this information are presented this non parametric approach to relative efficiency measurement is also used to obtain economic efficiency estimates for an industry as a whole without imposing a priori restrictions on the relative input and output weights

human capital pricing equations with an application to estimating the effect of schooling quality on earnings this paper formulates and estimates alternative models for the pricing of labor services we present economic models that rationalize empirical specifications in the literature and we offer evidence on the validity of those specifications widely used efficiency units models of labor services are inconsistent with evidence from the u s labor market a model of heterogeneous skills provides a more accurate description of earnings data we present evidence that the pursuit of comparative advantage and selective migration are important features of the u s labor market when these features are included in the model the only support for an effect of schooling quality on earnings is through the return to college education three interactions are empirically important in explaining log wage equations a between schooling quality and education b between regional labor market shocks and education and c between region of residence and regionof birth because of this third interaction which can arise from comparative advantage in the labor market no unique quality effect on returns to education can be defined independently of the market in which it is used

job information networks neighborhood effects and inequality this paper explores the theoretical and empirical literature to examine the use by different social groups of informal sources of information provided by friends relatives and acquaintances during job search and its consequences for the job market it also addresses the role of network structure and size the resource endowments of contacts and nature of the links between contacts to explain differences in the effects of job information networks in doing so the paper also turns to the sociology literature on job information networks and provides an economic perspective on such sociological concepts as strong versus weak ties inbreeding distance from structural holes etc the paper distinguishes between models of exogenous job information networks that is where individuals obtain job related information through a given social structure and endogenous job information networks which are social networks that result from individuals uncoordinated actions the paper pays special attention to such issues as physical and social proximity and sharing of information and discusses them in the context of the recent social interactions and neighborhood effects literature finally the paper outlines a model that integrates job information networks where interactions occur in business cycle frequencies with the dynamics of human capital formation which include the joint effects of parental community and neighborhood human capital and are set in life cycle frequencies for the purpose of organizing suggestions for future research and examining earned income inequality

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

efficiency measures and productivity indexes in the context of university library benchmarking data envelopment analysis dea has attracted considerable attention during the last few decades as an intuitively clear method for performance assessment theoretical developments have taken turns with empirical efficiency studies in this paper we empirically analyse performance differences across university libraries from different countries from a cross section and a longitudinal perspective we use the malmquist index approach to disentangle environmental efficiency from technical efficiency te to highlight performance differences eventually induced by environmental factors beyond the control of library management as well as to decompose productivity changes over time into changes in te and changes in technology in our cross section analysis we found that north american na libraries are more productive at higher input levels than the european libraries from germany and austria at which we looked in this contribution moreover the largest na libraries are still able to improve performance as t

comparing school ownership performance using a pseudo panel database a malmquist type index approach in this paper we propose a different way of using the malmquist index that allows us to further analyze the relative performance divergences between two groups of decision making units dmus over time when only a pseudo panel database is available to do this we extend the camanho and dyson 2006 one period malmquist type index cdmi for a pseudo panel database with a new pseudo panel malmquist index ppmi to illustrate the methodology we apply it to examine how the performance gap between public and private government dependent secondary schools in the basque country spain performed across three pisa waves 2006 2009 and 2012 the results suggest that performance is persistently and significantly higher for private government dependent schools than for public schools

the economic returns to schooling in the west bank and gaza strip the author uses micro data from the labor force surveys conducted in the west bank and the gaza strip during 1981 91 to show that during 1981 87 wage differences between schooling groups fell by well over one half this sharp reduction is associated with large increases in the size of the educated palestinian labor force since the returns to schooling for israeli jews were stable the decline in returns to schooling for palestinians is consistent with the notion that the returns to schooling in the territories were determined largely by the forces of supply and demand in a segmented market for skilled labor copyright 1995 by american economic association

the productivity of financial intermediation and the technology of financial product management financial intermediaries banks thrifts and life insurance companies have experienced low productivity over the last decade or two low productivity has manifested itself as a declining market share of their products relative to capital market assets in some cases low productivity caused a failure to meet contractual obligations embodied in their financial products these failures resulted in customer losses and or taxpayer losses when failed intermediaries were guaranteed by government agencies this productivity problem has been analyzed mostly from an economic science perspective by r c merton merton r c 1990 the financial system and economic performance j fin serv res 263 300 and z bodie bodie z 1990 pension funds and financial innovation finan mgmt autumn the focus of the economic analysis is the improvement of regulatory measures for intermediaries whose financial products are guaranteed by government agencies in this paper we take a management science perspective by

do substantial horizontal mergers generate significant price effects evidence from the banking industry this study examines the price effects of recent us bank mergers that substantially increased local market concentration using the deposit interest rates that banks offer their customers as our price measure we find that over the 1991 94 time period deposit rates offered by participants in substantial horizontal mergers and their local market rivals declined by a greater percentage than did deposit rates offered by banks not operating in markets in which such mergers took place we interpret our results as evidence that these mergers led to increased market power

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

does it pay to attend an elite private college cross cohort evidence on the effects of college type on earnings although a substantial and rising labor market premium is associated with college attendance in general little is known about how this premium varies across institutions of different types and across time in this paper we explicitly model high school students choice of college type characterized by selectivity and control based on individual and family characteristics including ability and parental economic status and an estimate of the net costs of attendance we estimate selectivity corrected outcome equations using data from both the national longitudinal study of the high school class of 1972 and high school and beyond which permit us to determine the effects of college quality on wages and earnings and how this effect varies across time even after controlling for selection effects strong evidence emerges of a significant economic return to attending an elite private institution and some evidence suggests this premium has increased over time

dynamics of retail bank branching in antwerp belgium 1991 2006 evidence from micro geographic data abstract we exploit a comprehensive new panel dataset on retailbank branch locations in 233 neighborhoods local markets in the metropolitan area of antwerp to describe i how between 1991 and 2006 the patterns of bank presence entry exit and choice deeply evolve and ii whether and how changes in these on the ground patterns systematically diverge across antwerp s different highly segregated neighborhoods we show that over the 15 year period under study entry and exit dynamics substantially intensify the level change in branch desert grows significantly and bank choice markedly declines and that between 1996 and 2001 these changes are robustly associated with the neighborhood average income in doing so we advance a new technique for generating spatial measures that both minimize the discretization bias and can be reliably linked to neighborhoods we demonstrate that the resulting measures are indeed more precise than traditional count measures

does compulsory school attendance affect schooling and earnings we establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws individuals born in the beginning of the year start school at an older age and can therefore drop out after completing less schooling than individuals born near the end of the year roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws we estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education the instrumental variables estimate of the return to education is close to the ordinary least squares estimate suggesting that there is little bias in conventional estimates every developed country in the world has a compulsory schooling requirement yet little is known about the effect these laws have on educational attainment and earnings 1 this paper exploits an unusual natural experiment to estimate the impact of compulsory schooling laws in the united states the experiment stems from the fact that children born in different months of the year start school at different ages while compulsory schooling laws generally require students to remain in school until their sixteenth or seventeenth birthday in effect the interaction of school entry requirements and compulsory schooling laws compel students born

income schooling and ability evidence from a new sample of identical twins we develop a model of optimal schooling investments and estimate it using new data on approximately 700 identical twins we estimate an average return to schooling of 9 percent for identical twins but estimated returns appear to be slightly higher for less able individuals simple cross section estimates are marginally upward biased these empirical results imply that abler individuals attain more schooling because they face lower marginal costs of schooling not because of higher marginal benefits

branch banking and the geography of bank pricing we show that bank branching tends to mitigate localized market power by broadening the geographic scope of competition among banks even though branch banking allows banks to differentiate themselves through their choices of branch locations banking services at peripheral locations will be priced more competitively when those locales are served by branch networks we develop a theoretical model in support of this view and offer empirical evidence

consolidation and bank branching patterns abstract this paper examines the association between consolidation and changes in levels of bank branching as measured by changes in the number of bank branches per capita using a specially constructed data set we address this issue as well as how this relationship varies with the type of consolidation and initial regulatory competitive and market conditions we find that merges where merging institutions have branch networks which overlap within a zip code within zip merger are strongly associated with a reduction in offices per capita in that zip code this result is robust across time and holds in both rural and urban areas the findings also suggest that contrary to popularly held views consolidation is not unambiguously negatively associated with changes in the number of banking offices per capita neither within market but not within zip mergers nor out of market mergers consistently show such a relationship we also find that the relationships between within zip and within market but not within zip mergers and changes in the number of bank offices per capita are more negative in low income neighborhoods than in other neighborhoods however because most states now have unrestricted branching and because savings associations are less prevalent and financially healthier than in the past these findings may not be indicative of future branching patterns

transmission of risk averse behavior in small firms small sized firms are typically more entrepreneurial and engage in more innovation and risk taking behavior for that reason they are considered the engines of future economic growth one policy for stimulating such activity is to provide government contracts for small firms however such contracts as typically written result in increased risk averse behavior on the part of small firms out of a desire by government officials to shift the risk to the firms this in turn results in a reduced level of innovative and entrepreneurial activity to eliminate the disincentive to engage in innovation and entrepreneurial activity government needs to bear the risk associated with such contracts one possible solution given the natural risk aversion of elected officials is to engage in a portfolio approach to small firm contracts by which the government can diversify away some of the risk

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

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

banking efficiency in the nordic countries abstract evidence of the relative competitiveness of the banking industries in three nordic countries is provided by applying data envelopment analysis of productivity on the national and the pooled data sets the analysis produces a detailed account of how well banks from different countries and different sizes may be prepared to meet the more intense competition of a common european banking market

dea ar profit ratios and sensitivity of 100 large u s banks abstract several important dea ar concepts were applied here to banking for the first time this application includes classification sensitivity uniqueness linked cones lcs and profit ratios notably large bank behavior seems to be explained better by profit ratios than by relative efficiency measures of dea efficiency ar efficiency and lc profit ratios were made for a bank panel of the u s s 100 largest banks in asset size from 1986 to 1991 high levels of inefficiency were found as in previous studies classification of the dea efficiency measures identified the inefficient dmus with some positive primal slacks sensitivity analysis of the dea efficiency measures showed that the extreme efficient classification was generally relatively insensitive to errors in the data the ars eliminated i 44 to 60 of the dea extreme efficient dmus and ii all of the banks with unprofitable actual profit ratios some statistical analyses highlight the superiority of the lc profit ratios relative to the ar efficiency measures

college choice and subsequent earnings results using swedish sibling data college choice and subsequent earnings results using swedish sibling data this paper investigates the relationship between college choice and annual earnings using within family variation in college choice the results show that earnings vary significantly between students who graduated from different types of colleges and the earnings premium is larger for those who graduated at an old university do birth order and family size matter for intergenerational income mobility evidence from sweden previous studies of intergenerational income mobility have not considered potential birth order or family size effects in the estimated income elasticity this paper estimates the intergenerational income elasticity by birth order position and family size the main finding of this paper is that the elasticity tends to decrease with birth order for a given family size especially for fathers and sons a comparison of family and neighborhood effects on grades test scores educational attainment and income evidence from sweden this paper compares sibling and neighborhood correlations in school performance educational attainment and income as a way to learn whether the neighborhood where a child grows up in might explain parts of the sibling similarities found in previous sibling correlation studies the results show that living in the same neighborhood does not seem to add much to the sibling similarity what more than parental income an exploration of what swedish siblings get from their parents in this paper we explore what factors other that parental income can explain why siblings tend to have such similar outcomes as previous correlation studies show our results show that parental involvement and attitudes especially propensity to plan ahead and willingness to postpone benefits to the future are particularly important for the sibling similarity

college choice and wages estimates using data on female twins the authors assess the impact of college quality on women s earnings and the influence of family and individual endowments on college choice using new data from a survey of identical and nonidentical twins born in minnesota the estimates reject models that ignore school choice the statistically preferred estimates suggest that ph d granting private universities with well paid senior faculty and smaller enrollments produce students who have significantly higher earnings later in life both the quantity of schooling and the quality of schooling resources are allocated to higher endowed individuals which exacerbates preexisting inequality in human capital and biases conventional estimates of school quality effects copyright 1996 by mit press

banking structure and employment growth recent studies have documented an association between financial structure and per capita income growth the relationship between financial structure and job growth by contrast is an unexplored issue of independent interest here we find that us nonmetropolitan employment grew faster in 1973 1996 where there were fewer locally owned bank offices and a more concentrated initial banking market structure these linkages were less stable in metropolitan areas in addition controlling for employment growth does not undermine the empirical linkage between initial bank structure and subsequent per capita income growth

spatial price competition a semiparametric approach we investigate the nature of price competition among firms that produce differentiated products and compete in markets that are limited in extent we propose an instrumental variables series estimator for the matrix of cross price response coefficients demonstrate that our estimator is consistent and derive its asymptotic distribution our semiparametric approach allows us to discriminate among models of global competition in which all products compete with all others and local competition in which products compete only with their neighbors we apply our semiparametric estimator to data from u s wholesale gasoline markets and find that in this market competition is highly localized

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

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

changes in college skills and the rise in the college wage premium the college wage premium for new labor market entrants rose sharply during the 1980s we ask how much of this change arose from changes in the skill level of the typical college graduate we find that skills attained prior to college as measured by standardized test scores and high school grades had no effect on the change in the college wage premium for men in contrast the returns to math ability rose considerably for women failing to account for math skills thus substantially overstates the growth in the female college wage premium skills acquired in college as reflected in the distribution of students across majors had important effects on the relative wages of men the trend away from low skill subjects such as education and toward high skill subjects such as engineering accounts for one fourth of the rise in the male college wage premium

schooling and labor market consequences of school construction in indonesia evidence from an unusual policy experiment between 1973 and 1978 the indonesian government engaged in one of the largest school construction programs on record combining differences across regions in the number of schools constructed with differences across cohorts induced by the timing of the program suggests that each primary school constructed per 1 000 children led to an average increase of 0 12 to 0 19 years of education as well as a 1 5 to 2 7 percent increase in wages this implies estimates of economic returns to education ranging from 6 8 to 10 6 percent

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

factor proportions and relative wages the supply side determinants of wage inequality supply side factors may contribute to rising wage inequality first certain changes in the supply of skills allegedly exacerbate wage inequality women s increased labor force participation and increased immigration are the leading candidates both allegedly reduce the wages of less skilled men however immigration s impact on wage inequality has been minor and the effects of women s participation is inconclusive second in evaluating the likelihood that human capital investment will mitigate future inequality evidence suggests that rising returns to education have increased the proportion of young people attending college limiting the growth of inequality among high wage workers

a note on banking efficiency in portugal new vs old banks following entry into the european community in 1986 portugal transformed rapidly its repressed banking system with deregulation the opening of borders the granting of new banking licenses and privatization in a more competitive banking system one would expect a priori an increase in operational efficiency this paper attempts to quantify the magnitude of efficiency gains over the years 1990 1995 moreover the paper documents the relative efficiency performance of new domestic banks not hampered by a legacy of inefficiency from the past they could operate nearer the efficiency frontier the case of portugal provides unique information on the joint effect of deregulation and the granting of new banking licenses on the change in operational efficiency of a previously repressed banking system

explaining international differences in male skill wage differentials by differences in demand and supply of skill this paper explores the hypothesis that wage differentials between skill groups across countries are consistent with a demand and supply framework using micro data from 15 countries we find that about one third of the variation in relative wages between skill groups across countries is explained by differences in net supply of skill groups the demand and supply framework does an even better job at explaining relative wages of low skilled workers

estimating input specific technical inefficiency the case of the tunisian banking industry abstract this paper presents an econometric model to estimate input specific technical efficiency iste in a panel data framework it extends the few existing models to estimate iste it can be applied to any flexible functional form and technical inefficiency is firm specific and time variant this model is applied to obtain estimates of technical inefficiency specific to factors of production in the tunisian banking industry it is shown that technical efficiency of labor and capital inputs are decreasing over time labor input is more inefficiently used than capital input and banks which are relatively more efficient in using capital input are less efficient in using labor input

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