complementarities in the search for innovation managing markets and relationships abstract extant research has characterized a firm s search for external knowledge in its innovation activities as either relational or transactional in nature the former implies that a firm chooses and develops collaborative relationships with knowledge sources like universities customers or suppliers while the latter suggests transactions governed by markets for technology we argue that prior literature has ignored that both search strategies are interrelated and complementary adopting one strategy has a higher marginal return on innovation performance if the other one is present moreover we suggest the benefits from complementarity to be higher when a firm is more distant to the technological frontier in the industry and when markets for technology in that industry are shallow we test our hypotheses on a sample of 3921 german firms from 2001 to 2009 and find support for our hypotheses

measuring the incentives to learn in colombia using new quantile regression approaches abstract this paper employs newly developed quantile regression techniques to investigate a policy that could differentially affect students performance the colombian vouchers were assigned using lotteries and were renewable as long as the students maintained satisfactory academic progress this second aspect of the program may provide incentives for low attainment students to work harder the evidence supports the hypothesis that incentives could account for the impact of the vouchers including lower repetition rate the effect of the vouchers is largest in the lower tail of the educational attainment distribution a possibility that was conjectured by others but has not yet been confirmed empirically the evidence suggests that the incentive effect of the program increases weak students test scores by at least 0 1 standard deviations roughly the score gain associated to a half year of school learning

one market one number a composite indicator assessment of eu internal market dynamics we consider the lack of consensus about an appropriate theoretical framework linking sub indicators as a defining characteristic of composite indicators this intrinsic feature implies uncertainties about the appropriate normalization and aggregation of the raw data the two are related index theory offers some valuable guidelines about their connection yet these do not fully solve the basic problem of expert disagreement we embed such residual disagreement in the aggregation method itself specifically we apply an impartial benefit of the doubt weighting procedure where weight restrictions incorporate the available information on experts opinions we apply this procedure to the dynamic performance assessment of eu internal market effects thereby highlighting its capacity to disaggregate member states observed performance shifts into changes relative to benchmarks and performance changes of the benchmarks i e catching up versus genuine progress our results indicate that the latter factor is more important in explaining the observed progress

do better schools matter parental valuation of elementary education the evaluation of numerous school reforms requires an understanding of the value of better schools given the difficulty of calculating the relationship between school quality and student outcomes i turn to another method and use house prices to infer the value parents place on school quality i look within school districts at houses located on attendance district boundaries houses then differ only by the elementary school the child attends i thereby effectively remove the variation in neighborhoods taxes and school spending i find that parents are willing to pay 2 5 percent more for a 5 percent increase in test scores this finding is robust to a number of sensitivity checks

energy price shocks input price changes and developmental implications a translog model applied to puerto rico the energy shocks of the 1970s that altered the relative price relationships between factor inputs and induced structural changes are analysed with the use of a translogarithmic cost function that incorporates the inputs capital labour and energy the developmental implications of these structural changes on a small open and energy capital importing region are emphasized taking the case of puerto rico as an example in terms of the partial elasticities of substitution the capital labour relationship moved from highly substitutable in the pre 1973 period to weakly complementary thereafter the energy labour association was transformed from high to low substitutability and that of energy capital from highly complementary to substitute

economic growth and greenhouse gases in europe a non radial multi sector nonparametric production frontier analysis abstract energy use has become a topical issue when assessing the economic growth of countries indeed energy use gives rise to greenhouse gas emissions which are undesirable side products of economic growth in this paper we present a non radial multi sector nonparametric production frontier approach specially tailored for addressing this issue our approach is consistent with previous works and in line with recent policy and regulation implementations we also make use of second stage country and sector level regression analyses to investigate how the efficiency results are affected by exogenous factors we apply our method to the case of 10 sectors in 19 european countries our results highlight the need for policy and regulation implementations for each sector individually indeed our efficiency and regression results show that there exists a sector heterogeneity and that the room for increasing economic growth reducing greenhouse gas emissions is clearly different for each sector in every country finally our results highlight two sectors 1 agriculture and 2 electricity gas and water and that the europe 2020 objectives are well set since they target the most inefficient countries sectors

multinational operation ownership and efficiency differences in the international oil industry abstract although state involvement in market systems often leads to inefficiency this influence in the oil industry is not dwindling due to strong growth of some state oil companies based on this background there are concerns about how state firms can continue to stay relevant in the international oil industry by offsetting inefficiencies due to state control this study assesses the effects of multinational operations on the performance of oil firms this is achieved by comparing productive and scale efficiencies of state and private oil companies as well as state multinationals and private multinationals a dataset of 50 firms each year from 2001 to 2010 reveals that although multinational operation is important in reducing productive inefficiencies of state firms it does not mitigate scale inefficiencies of state owned firms state firms should therefore make multinational operations a key policy direction since this will provide a transformative agenda towards equally competing with their private counterparts however better efforts need to be paid in reducing scale inefficiencies that are pervasive among state owned oil firms providing better controls on firm size will provide better drive towards future efficient production levels

school finance reform assessing general equilibrium effects abstract in 1994 the state of michigan implemented one of the most comprehensive school finance reforms undertaken to date in any of the states understanding the effects of the reform is thus of value in informing other potential reform initiatives in addition the reform and associated changes in the economic environment provide an opportunity to assess whether a simple general equilibrium model can be of value in framing the study of such reform initiatives in this paper we present and use such a model to derive predictions about the effects of the reform on housing prices and neighborhood demographic compositions broadly our analysis implies that the effects of the reform and changes in the economic environment are likely to have been reflected primarily in housing prices and only modestly on neighborhood demographics we find that evidence for the detroit metropolitan area from the decade encompassing the reform is largely consistent with the predictions of the model

economies of scope and the cash crop food crop debate in senegal abstract the government of senegal plans to achieve national food self sufficiency by inducing farmers to switch away from cash crops toward food crop production this paper examines selected economic consequences of the planned substitution using empirical data recently collected in southeastern senegal cost function estimates suggest that farmers are currently producing too much food crop and too little cash crop output given existing technology and observed relative prices moreover economies of scope in producing both food crops and cash crops on the same farm result in a 22 cost saving relative to growing both types of crops on separate specialized farms

american education research changes tack for a quarter century american education researchers have tended to favour qualitative and descriptive analyses over quantitative studies using random assignment or featuring credible quasi experimental research designs this has now changed in 2002 and 2003 the us department of education funded a dozen randomized trials to evaluate the efficacy of pre school programmes up from one in 2000 in this essay i explore the intellectual and legislative roots of this change beginning with the story of how contemporary education research fell out of step with other social sciences i then use a study in which low achieving high school students were randomly offered incentives to learn to show how recent developments in research methods answer ethical and practical objections to the use of random assignment for research on schools finally i offer a few cautionary notes based on results from the recent effort to cut class size in california copyright 2004 oxford university press

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

measurement matters perspectives on education policy from an economist and school board member one of the potential strengths of the no child left behind nclb act enacted in 2002 is that the law requires the production of an enormous amount of data particularly from tests which if used properly might help us improve education as an economist and as someone who served 13 years on the school committee in brookline massachusetts until may 2009 i have been appalled by the limited ability of districts to analyze these data i have been equally appalled by the cavalier manner in which economists use test scores and related measures in their analyses the summary data currently provided are very hard to interpret and policymakers who typically lack statistical sophistication cannot easily use them to assess progress in some domains most notably the use of average test scores to evaluate teachers or schools the education community is aware of the biases and has sought better measures the economics and statistics communities have both responded to and created this demand by developing value added measures that carry a scientific aura however economists have largely failed to recognize many of the problems with such measures these problems are sufficiently important that they should preclude any automatic link between these measures and rewards or sanctions they do however contain information and can be used as a catalyst for more careful evaluation of teachers and schools and as a lever to induce principals and other administrators to act on their knowledge

measuring efficiency in education an analysis of different approaches for incorporating non discretionary inputs measuring efficiency in the education sector is a highly complex task one of the reasons is that the main resource of schools the type of students they have lie outside of their control which means that it must be treated differently to other factors in analysis this study examines the different options available in the literature for incorporating non controllable inputs in a data envelopment analysis in order to determine the most appropriate model for evaluating schools our empirical study presents the results obtained using the model proposed by fried et al 1999 though we use bootstrap techniques to avoid problems of bias in the estimations

equity and educational performance in this paper we review the main issues under discussion in the field of economics of education with a special focus on latin america we seek to organize the debate about educational policies by showing how these policies respond to different models based on different assumptions and hypotheses about how the educational system functions methodological and informational problems make it difficult to test the validity of different policies this would explain the enormous number of studies in the field that conclude with conflicting policy prescriptions we also use data from chile to analyze the importance of the school in educational outcome and to explore the heterogeneous impacts of student and school characteristics on educational achievement the results obtained allow us to conclude that the school plays a very important role in explaining educational achievement we also find that low income students stand to benefit the most from attending a private school however this conclusion is valid for a marginal analysis and does not necessarily apply to a massive reallocation of students among schools

bias and precision in the dea two stage method in data envelopment analysis dea the two stage method is a popular procedure for accounting for exogenous influences on efficiency with the conventional two stage method a dea is first conducted using only traditional endogenous inputs and outputs then the first stage dea scores are regressed on the environmental contextual exogenous inputs of interest the regression outcomes are used to identify exogenous inputs that influence the first stage dea scores to a statistically significant degree and to adjust dea scores to account for these influences herein it is demonstrated empirically that the conventional method exhibits substantial bias and low precision with the degree of bias and precision affected by input variance and correlation a reverse two stage procedure that yields estimates without the bias and precision problems that compromise the validity of the conventional method s estimates is suggested

the central role of noise in evaluating interventions that use test scores to rank schools many programs reward or penalize schools based on students average performance mean reversion is a potentially serious hindrance to the evaluation of such interventions chile s 900 schools program p 900 allocated resources based on cutoffs in schools mean test scores this paper shows that transitory noise in average scores and mean reversion lead conventional estimation approaches to overstate the impacts of such programs it further shows how a regressiondiscontinuity design can be used to control for reversion biases it concludes that p 900 had significant effects on test score gains albeit much smaller than is widely believed

incentives in organizations n 1975 steven kerr published on the folly of rewarding a while hoping for b the argument was simple you get what you pay for kerr distilled this unifying theme from a disparate set of examples involving politicians soldiers doctors orphanage directors professors and students as well as manufacturing and clerical employees and even human resource managers from these examples kerr pp 77980 concluded that two main causes of distorted incentives are fascination with an objective criterion where individuals seek to establish simple quantifiable standards against which to measure and reward performance and overemphasis on highly visible behaviors when some parts of the task are highly visible while others are not it took agency theory 15 years to express kerr s title not to mention to evaluate or extend his conclusions during this period agency theory was obsessed with the tradeoff between incentives and insurance even though clear eyed observations like kerr s about the design and performance of real incentive contracts suggested that several other issues are at least as important fortunately recent work has brought agency theory not only to kerr s position but beyond in this paper i summarize four new strands in agency theory that help me think about incentives in real organizations as a point of departure i begin with a quick sketch of the classic agency model i then discuss static models of objective performance measurement that sharpen kerr s argument repeated game models of subjective performance assessments incentives for skill development rather than simply for effort and incentive contracts between versus within organizations i con

leveraging lotteries for school value added testing and estimation conventional value added models vams compare average test scores across schools after regression adjusting for students demographic characteristics and previous scores this article tests for vam bias using a procedure that asks whether vam estimates accurately predict the achievement consequences of random assignment to specific schools test results from admissions lotteries in boston suggest conventional vam estimates are biased a finding that motivates the development of a hierarchical model describing the joint distribution of school value added bias and lottery compliance we use this model to assess the substantive importance of bias in conventional vam estimates and to construct hybrid value added estimates that optimally combine ordinary least squares and lottery based estimates of vam parameters the hybrid estimation strategy provides a general recipe for combining nonexperimental and quasi experimental estimates while still biased hybrid school value added estimates have lower mean squared error than conventional vam estimates simulations calibrated to the boston data show that bias notwithstanding policy decisions based on conventional vams that control for lagged achievement are likely to generate substantial achievement gains hybrid estimates that incorporate lotteries yield further gains

productivity across industries and countries time series theory and evidence the authors examine whether convergence in aggregate productivity is also occurring at the industry level in fourteen oecd countries from 1970 to 1987 using both cross section and time series methods they find convergence in some sectors such as services however surprisingly the authors find that convergence does not hold for the manufacturing sector decomposing aggregate convergence into industry productivity gains and changing sectoral shares of output they find the service sector to be responsible for the bulk of cross country convergence to the united states the authors develop a new result on the asymptotic normality of panel unit root estimators to formally test within sector convergence copyright 1996 by mit press

rural urban migation informal sector and development policies a theoretical analysis abstract a theoretical model of rural urban migration has been developed with special reference to the informal sector the wage rate and employment in the informal sector are determined endogenously the paper shows the simultaneous existence of open unemployment and informal sector in the urban area in migration equilibrium the effects of alternative subsidy policies on unemployment and welfare of the workers are studied

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

value added educational accountability approaches and their effects on schools rankings evidence from chile abstract value added models have been proposed to analyze different aspects related to school effectiveness on the basis of student growth there is consensus in the literature about the need to control for socioeconomic status and other contextual variables at student and school level in the estimation of value added for which the methodologies employed have largely relied on hierarchical linear models however this approach is problematic because results are based on comparisons to the school s average implying no real incentive for performance excellence meanwhile activity analysis models to estimate school value added have been unable to control for contextual variables at both the student and school levels in this study we propose a robust frontier model to estimate contextual value added which merges relevant branches of the activity analysis literature namely metafrontiers and partial frontier methods we provide an application to a large sample of chilean schools a relevant country to study due to the reforms made to its educational system that point out to the need of accountability measures results indicate not only the general relevance of including contextual variables but also how they contribute to explaining the performance differentials found for the three types of schools public privately owned subsidized and privately owned fee paying also the results indicate that contextual value added models generate school rankings more consistent with the evaluation models currently used in chile than any other type of evaluation models

school choice stratification and information on school performance lessons from chile in the early 1980s chile implemented a nationwide school choice system under which the government finances education via a flat per student sub sidy or voucher to the public or private school chosen by a family at present about 94 percent of all schools public religious and secular private are voucher funded more than half of urban schools are private and most of these operate as for profit institutions 1 since the early 1990s chile has also publicized information on school performance and increased per pupil expen diture substantially despite these and other reforms chile has found it challenging to improve students learning outcomes 2 hsieh and urquiola find that the country s rel ative performance in international tests did not change much between 1970 and 1999 3 its performance on the 2000 programme for international student assessment pisa is not only much lower than the oecd average but is similar to that of other latin american countries and low relative to countries with similar income per capita

technological change technological catch up and capital deepening relative contributions to growth and convergence we decompose labor productivity growth into components attributable to 1 technological change shifts in the world production frontier 2 technological catch up movements toward or away from the frontier and 3 capital accumulation movement along the frontier the world production frontier is constructed using deterministic methods requiring no specification of functional form for the technology nor any assumption about market structure or the absence of market imperfections we analyze the evolution of the cross country distribution of labor productivity in terms of the tripartite decomposition finding that technological change is decidedly nonneutral and that both growth and bipolar international divergence are driven primarily by capital deepening jel o30 o47 d24

why european banks are less profitable than u s banks a decomposition approach abstract the low profitability of european banks relative to their u s counterparts has recently raised concerns among policy makers and researchers this paper attempts to shed light on this issue by using the o donnell 2012 decomposition approach this approach enables us to decompose the relative profitability of european banks into an output input price index and a total factor productivity index with the former further decomposed into two price indexes and the latter further into four productivity and efficiency measures our results show that european banks profitability was not only weak but also deteriorated over time our further analysis shows that the decline in the output input price index was due to declines in relative lending rate and relative return on securities and an increase in funding costs while the decline in the productivity index was driven by declines in technical efficiency scale efficiency and residual mix efficiency

rank dynamics and club convergence of sustainable development for countries around the world abstract assessment of country level sustainable development is a critical research topic entrenched in the global battle against climate change this study employs the frontier approach combined with convergence analysis to assess the sustainable development for a set of 121 countries over 1990 2014 focusing on analyzing the countries rank dynamics and convergence behavior the levels of the countries sustainable development are captured by data envelopment analysis a nonparametric frontier approach that can jointly assess a country s economic and environmental performance reflecting the divergent views on the importance of economic and environmental objectives in the pursuit of sustainability the proposed approach generates the countries sustainability scores by prioritizing either economic or environmental criterion this study finds that developed countries have significantly outperformed developing countries if environmental criterion takes precedence over economic criterion in performance assessment moreover regardless of the model employed there is strong evidence of club convergence i e convergence in subgroups of countries to different steady states rather than convergence in full sample we analyze the pattern of convergence paths and discuss policy implications obtained from our empirical findings

the economics of schooling production and efficiency in public schools n recent years public and professional interest in schools has been heightened by a spate of reports many of them critical of current school policy these policy documents have added to persistent and long standing concerns about the cost effectiveness and fairness of the current school structure and have made schooling once again a serious public issue as in the past however any renewed interest in education is likely to be short lived doomed to dissipate as frustration over the inability of policy to improve school practice sets in this frustration about school policy relates directly to knowledge about the educational production process and in turn to underlying research on schools although the educational process has been extensively researched clear policy prescriptions flowing from this research have been difficult to derive 2 there exists however a consistency to the research findings that does have an immediate application to school policy schools differ dramatically in quality

factor substitution approach to testing the time variations in production the case of taiwan s manufacturing this paper is devoted to studying the time variations in the series of elasticities of factor substitution which in a sense manifests changes in production technology and structure a lkm translog cost function model is used to estimate the allen uzawa elasticities of substitution for taiwan s manufacturing sector in 1965 91 the variations are analysed using a regression model which incorporates the linear spline setting and income variable empirical results indicate that obvious structural breaks in the elasticity series conform to major exogenous disturbances such as worldwide energy crises and developmental policy changes

families schools and primary school learning evidence for argentina and colombia in an international perspective this article presents evidence on the associations between family background school characteristics and student performance in primary school in argentina colombia and several comparison countries as a general pattern educational performance is strongly related to family background weakly to some institutional school features and hardly to schools resource endowments in an international perspective family background effects are relatively large in argentina and relatively small in colombia a specific argentine feature is the lack of performance differences between rural and urban areas a specific colombian feature is the lack of significant between gender performance differences nonnative students and students not speaking spanish at home perform particularly weak in both countries in argentina students perform better in schools with a centralized curriculum and ability based class formation

hypercongestion in production correspondences an empirical exploration this empirical contribution reviews the rather limited existing literature measuring congestion in production it first compares current ways to measure congestion using nonparametric specifications of technologies in particular it focuses on the magnitude and incidence of the congestion detected in empirical studies using traditional radial efficiency measures thereafter it shows the limitations of this radial measurement and how alternative measurement schemes may reveal higher amounts of congestion then the new more general methodology of measuring s congestion is presented in particular we first present a numerical example to illustrate the way the s disposable technologies allow to capture more extreme forms of congestion by setting empirically determined upper bounds to the wasting of inputs then an empirical illustration is presented based on an existing sample of data a final section concludes

the effects of generalized school choice on achievement and stratification evidence from chile s voucher program in 1981 chile introduced nationwide school choice by providing vouchers to any student wishing to attend private school as a result more than 1000 private schools entered the market and the private enrollment rate increased by 20 percentage points with greater impacts in larger more urban and wealthier communities we use this differential impact to measure the effects of unrestricted choice on educational outcomes using panel data for about 150 municipalities we find no evidence that choice improved average educational outcomes as measured by test scores repetition rates and years of schooling however we find evidence that the voucher program led to increased sorting as the bbestq public school students left for the private sector d 2005 elsevier b v all rights reserved

the technical efficiency of schools in chile this paper assesses the technical efficiency of schools in chile which is defined as the capacity of schools to generate the maximum output academic achievement given the quantity of inputs they use two alternative methodological approaches for measuring efficiency are used i estimation of a stochastic production frontier and ii data envelopment analysis dea which allows identification of the efficient production frontier of the schools analysed nonparametrically each of these techniques has advantages and limitations which are discussed in the paper they lead however to the same conclusions when a sample of 2000 schools is analysed the results obtained provide interesting points for educational policy discussion in chile

textile manufacturing in eight developing countries does business environment matter for firm technical efficiency abstract production frontiers with technical inefficiency determinants are estimated using stochastic models for textile manufacturing in eight developing countries encompassing about 800 firms inefficiency determinants are considered either on an individual basis or in the form of composite indicators reflecting in house or managerial factors and various dimensions of the external environment although each of these two categories of factors is statistically significant the former proves more influential in the explanation of the difference in efficiency between firms simulations are then proposed to assess the efficiency levels that would occur if firms had the opportunity to produce in the most favourable productive environments

assessing school efficiency in portugal using fdh and bootstrapping this study explores a new data set that contains information both on inputs and outputs for a sample of portuguese secondary schools an fdh reference technology is used to determine radial technical efficiency scores and slacks although it is known that there is no reason to assume convexity in the study of education efficiency frontiers this is the first study ever to use fdh at the school level effectively relaxing the convexity assumption a two stage approach is used whereby the significant environmental variables that explain fdh efficiency scores and slacks are identified for the purpose of statistical inference the first application of the bootstrapping algorithms suggested by simar and wilson 2003 is conducted the study concludes that the unemployment rate access to health care services adult education and living infrastructures are determinants of school efficiency the differences between the coast and the interior of portugal seem to be more relevant as far as school efficiency is

migration trade unions and the informal sector a note on calvo tends to be very sticky a feature which renders some of the standard policies for reducing urban unemployment or underemployment totally ineffective in particular it is observed that in the calvo model a first best optimum cannot be obtained without the imposition of some migration barriers in this note we attempt to generalize the calvo model by incorporating the following new features first we distinguish between the two components of the urban sector the modern formal part and the traditional informal part secondly the individuals are assumed to migrate from the rural to the urban sector in response to a differential in expected utility rather than in expectedincome thereby highlighting the role of risk aversion in individual migration decisions finally following the new literature on trade union behavior 2 the present model posits a utilitarian objective function for the trade union a formulation which is considered an improvement over the one put forward by calvo an important conclusion of the present exercise which sharply contrasts calvo s conclusion is that the government by setting its policies correctly can achieve a first best optimum for the economy this difference in result is due obviously to the differences in specification in particular of the objective function of the trade union

how accountability pressure on failing schools affects student achievement abstract although an emerging body of evidence has shown that the threat of sanctions on low performing schools can raise student test scores in the short run the extent to which these test score improvements are due to schools manipulation of the accountability system has remained uncertain in this paper i provide two new strands of evidence to evaluate the relative importance of educational reforms and gaming behavior in generating test score gains by threatened schools first using a regression discontinuity design that exploits florida s system of imposing sanction threats on the basis of a cutoff level of performance i estimate medium run effects on student test scores from having attended a threatened elementary school threat induced math improvements from elementary school largely persist at least through the first 1 to 2 years of middle school while evidence for persistence of reading improvements is less consistent second i analyze the effects of sanction threats on various features of educational production and i find that sanction threats raise school spending on instructional technology curricular development and teacher training both strands of evidence are consistent with a predominant role for educational reforms in generating test score gains by threatened schools

productivity change and its determinants among leading mobile operators in europe the european mobile telecommunications industry has seen increased competition and market saturation in recent years so improving productivity will become crucially important for mobile operators in the near future this study adopts a bootstrap malmquist index approach to estimate productivity change among a sample of 23 of europe s leading mobile operators over the 2008 to 2009 period using a second stage regression this article also analyses the determinants of productivity changes in terms of regulation competition and ownership structure the results show that mobile companies operating in countries that have recently joined the eu have a positive association with productivity change in contrast to their counterparts in south east europe concerning market competition the leading mobile operators that experience higher productivity changes operate in more concentrated markets the results also indicate that international mobile operators perform better in terms of productivity change than their

are ceos really paid like bureaucrats a common view is that there is little correlation between firm performance and ceo pay using a new fifteen year panel data set of ceos in the largest publicly traded u s companies we document a strong relationship between firm performance and ceo compensation this relationship is generated almost entirely by changes in the value of ceo holdings of stock and stock options in addition we show that both the level of ceo compensation and the sensitivity of compensation to firm performance have risen dramatically since 1980 largely because of increases in stock option grants

identification of treatment effects under imperfect matching with an application to chinese elite schools abstract this paper extends the treatment effect framework for causal inference to contexts in which the instrument appears in a data set that can only be linked imperfectly to the treatment and outcome variables contained in another data set to overcome this problem i form all pairwise links between information on the instrument and information on the treatment and outcome matched by the commonly recorded personal characteristics in both data sets i show how these imperfect conditional matches can be used to identify both the average and distributional treatment effects for compliers of the common units of the two data sets this multiple data source approach is then applied to analyze the effect of attending an elite middle school in a chinese city where schools admissions lottery records can only be linked imperfectly to the administrative student records

report cards the impact of providing school and child test scores on educational markets this paper studies study the impact of providing school and child test scores on subsequent test scores prices and enrollment in markets with multiple public and private providers a randomly selected half of the sample villages markets received report cards this increased test scores by 0 11 standard deviations decreased private school fees by 17 percent and increased primary enrollment by 4 5 percent heterogeneity in the treatment impact by initial school quality is consistent with canonical models of asymmetric information information provision facilitates better comparisons across providers improves market efficiency and raises child welfare through higher test scores higher enrollment and lower fees

which school attributes matter the influence of school district performance and demographic composition on property values abstract increasing levels of segregation in american schools raises the question do home buyers pay for test scores or demographic composition this paper uses connecticut panel data spanning eleven years from 1994 to 2004 to ascertain the relationship between property values and school district attributes such as student test scores and the racial and ethnic composition of the student body town and census tract fixed effects are included to control for neighborhood unobservables the effect of changes in school district attributes is also examined over a decade long time frame in order to focus on the effect of long run changes which are more likely to be capitalized into prices the study finds strong evidence that increases in percent hispanic have a negative effect on housing prices in connecticut but mixed evidence concerning the impact of test scores on property values student test scores also appear to have increased in importance for explaining housing prices in recent years while the importance of percent hispanic has declined finally the study finds that estimates of property tax capitalization increase substantially when the analysis focuses on long run changes

constant utility paths and irreversible global warming this paper shows that the hartwick rule for sustainable utility with depletable resources still applies to the case of the greenhouse effect from fossil fuel carbon emissions although a carbon tax is necessary for sustainable utility it is sufficient that the sum of net energy rents and carbon tax revenues is invested in reproducible capital examination of recent savings rates and energy cost shares suggests that this may be difficult to achieve with current global savings rates jel classification q32

quality disclosure and certification theory and practice this essay reviews the theoretical and empirical literature on quality disclosure and certification after comparing quality disclosure with other quality assurance mechanisms and describing a brief history of quality disclosure we address two sets of theoretical issues first why don t sellers voluntarily disclose through a process of unraveling and given the lack of unraveling is it desirable to mandate seller disclosure second when we rely on certifiers to act as the intermediary of quality disclosure do certifiers necessarily report unbiased and accurate information we further review empirical evidence on these issues with a particular focus on healthcare education and finance the empirical review covers quality measurement the effect of third party disclosure on consumer choice and seller behavior as well as the economics of certifiers jel d18 k32 l15 m31

rural urban migration in economic development abstract this paper provides a review of the theoretical literature on rural urban migration in contemporary ldcs the paper begins with a brief discussion of the lewis model before going on to discuss the todaro and the harris todaro models and the large literature which these models have spawned the question of job search in the context of migration and the role of family members in migration decisions are considered next the paper then takes a closer look at the informal sector and also sets out alternative migration functions to the ones usually employed in the literature the paper concludes with a brief note on some of the important implications arising from our study

beyond incentives do schools use accountability rewards productively we use a regression discontinuity design to analyze an understudied aspect of school accountability systems how schools use financial rewards for two years california s accountability system financially rewarded schools based on a deterministic function of test scores qualifying schools received per pupil awards amounting to about 1 of statewide per pupil spending corroborating anecdotal evidence that awards were paid out as teacher bonuses we find no evidence that winning schools purchased more instructional material increased teacher hiring or changed the subject specific composition of their teaching staff most importantly we find no evidence that student achievement increased in winning schools supplemental materials for this article are available online

the use and usefulness of performance measures in the public sector the paper focuses on the empirical evidence on the use and usefulness of performance measures in the public sector it begins with consideration of the features of the public sector which make the use of performance measures complex the issues of multiple principals and multiple tasks it discusses the form that performance measures may take the use made of these measures and the responses that individuals may make to them empirical examples from the fields of education and health with a focus on the usa and uk are examined there is clear evidence of responses to such measures some of these responses improve efficiency but others do not and fall into the category of gaming generally there has been little assessment of whether performance measures bring about improvements in service the paper ends with consideration of how such measures should be used and what measures are useful to collect

cost and learning efficiency drivers in australian schools a two stage network dea approach this article explore performance issues in australian public schools using a two stage dea network model which accounts simultaneously for both cost and learning efficiency levels in the cost efficiency stage different types of expenses and investments are employed to support a given number of students teachers and administrative staff in the learning efficiency stage these groups of individuals help to produce important outputs related to performance in student tests and school rankings results indicate that australian public schools are heterogeneous policy implications are also discussed

the promise and pitfalls of using imprecise school accountability measures in recent years most states have constructed elaborate accountability systems using school level test scores however because the median elementary school contains only 69 children per grade level such measures are quite imprecise we evaluate the implications for school accountability systems for instance rewards or sanctions for schools with scores at either extreme primarily affect small schools and provide weak incentives to large ones nevertheless we conclude that accountability systems may be worthwhile even in states with aggressive financial incentives the marginal reward to schools for raising student performance is a small fraction of the potential labor market value for students

the benefit of efficiency improvement on growth and convergence a study using japan panel data abstract empirical results through a fixed effects regression model show that technological catch up is three times as effective as capital deepening but both have done much to cause economic convergence among japanese prefectures regions results are contrary to existing research on east asian growth experience

teacher pay and school productivity exploiting wage regulation abstract the impact of teacher pay on school productivity is a central concern for governments worldwide yet evidence is mixed in this paper we exploit a feature of teacher labour markets to determine the impact of teacher wages teacher wages are commonly set in a manner that results in flat wages across heterogeneous labour markets this creates an exogenous gap between the outside labour market and inside regulated wage for teachers we use the centralised wage regulation of teachers in england to examine the effect of pay on school performance we use data on over 3000 schools containing around 200 000 teachers who educate around half a million children per year we find that teachers respond to pay a ten percent shock to the wage gap between local labour market and teacher wages results in an average loss of around 2 in average school performance in the key exams taken at the end of compulsory schooling in england

information shocks and the dynamics of the housing market in this paper we analyze housing market reactions to the release of previously unpublished information on school quality using high quality housing data which precisely bracket the timing of the information shock we investigate housing price dynamics within school catchment areas we find a robust short term housing market reaction to the publication of school quality indicators suggesting that this information was new to the households and that households are willing to pay for better schools the publication effect does not seem to be permanent as prices revert to pre publication levels after two to three months

energy substitution in u s manufacturing a regional approach one response of economists to energy market developments of the 1970s was to launch a series of studies in which the objective was to estimate energy substitution parameters characterizing important sectors of the u s economy relatively high substitution elasticities between energy and other inputs would permit firms to mitigate the effects of energy price increases by shifting to less energy intensive factor proportions the seminal work in this effort was carried out by berndt and wood 5 griffin and gregory 14 pindyck 28 halvorsen 16 and fuss 12 the research was substantially abetted by developments in production theory where the work of mcfadden 23 diewert 8 and christensen jorgenson and lau 6 yielded new and flexible production and cost function forms empirical work on energy substitution has continued 2 for the most part the data analyzed have been highly aggregative applying to say total u s manufacturing or perhaps to the various two digit sectors comprising that total to date little effort has been given to investigating energy substitution relationships at the regional level in the u s this is unfortunate since we know that the u s economy is actually composed of regions which are differently endowed with resources have developed at different rates and are comprised of different sectoral mixes the distinct possibility exists that regions differ in terms of the way in which energy inputs relate to other inputs in production furthermore even though the energy crisis may seem to be a national phenomenon national policy responses are worked out within a context of shifting and colliding regional conflicts stemming in large part from real or imagined perceptions of how energy market developments impact different regions it would seem especially important therefore to identify

human capital and convergence a production frontier approach using nonparametric production frontier methods we decompose labor productivity growth into components attributable to technological change shifts in the world production frontier technological catch up movements toward or away from the frontier and physical and human capital accumulation movements along the frontier we find that 1 technological change is decidedly nonneutral 2 productivity growth is driven primarily by physical and human capital accumulation 3 the increased international dispersion of productivity is explained primarily by physical capital accumulation and 4 international polarization the shift from a unimodal to a bimodal distribution is brought about primarily by efficiency changes technological catch up

on the evolution of the world income distribution the post world war ii period has seen substantial changes in the distribution of gdp per worker around the world in the upper half of the distribution a number of countries have exhibited large increases in income relative to the richest countries in the bottom half several countries have seen incomes fall relative to the richest countries the net result of these changes is a movement in the shape of the world income distribution from something that looks like a normal distribution in 1960 to a bi modal twin peaks distribution in 1988 projecting these changes into the future suggests a number of interesting ndings first it seems likely that the united states will lose its position as the country with the highest level of gdp per worker second growth miracles have been more common in recent decades than growth disasters if these dynamics continue the future income distribution will involve far more rich countries and far fewer poor countries than currently observed

school markets the impact of information approximating schools effectiveness abstract the impact of competition on school performance is likely to depend on whether parents are informed about schools effectiveness or value added which may or may not be correlated with absolute measures of their quality and on whether this information influences their school choices thereby affecting schools market outcomes this paper explores this by considering chile s sned program which seeks to identify effective schools selecting them from homogeneous groups of comparable institutions its results are widely disseminated and the information it generates is different from that conveyed by a simple test based ranking of schools which turns out to approximate a ranking based on socioeconomic status we use a sharp regression discontinuity to estimate the effect that being identified as a sned winner has on schools enrollment tuition levels and socioeconomic composition through five applications of the program we find no consistent evidence that winning a sned award affects these outcomes

how do school report cards affect school choice decisions we estimate the effect of information about school achievement that is disseminated to the public through websites and school report cards on school choice decisions we find that students are more likely to leave their school when public information reveals poor school level performance some parents school choice decisions respond to information soon after it becomes available others including non english speaking parents alter their school choice decisions only in response to information that has been disseminated widely and discussed in the media parents in low income neighbourhoods are most likely to alter their school choice decisions in response to new information jel classification i21 d83 les auteurs evaluent les effets de l information sur la performance des ecoles diffusee au public via les sites web ou les bulletins sur les decisions de choix d ecole il appert que les etudiants sont davantage susceptibles de quitter leur ecole quand l information publique revele sa pauvre performance les decisions de choix d ecole par certains parents repondent a l information tot apres que l information devient disponible d autres incluant les parents dont l anglais n est pas la premiere langue ne modifient leurs decision de choix d ecole qu en reponse a une information qui a ete vastement disseminee et discutee dans les medias les parents des milieux defavorises sont moins susceptibles de modifier leur decision de choix d ecole en reponse a l information nouvelle

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

relative sources of european regional productivity convergence a bootstrap frontier approach enflo k and hjertstrand p relative sources of european regional productivity convergence a bootstrap frontier approach regional studies this paper addresses the issue of western european regional productivity growth and convergence by means of data envelopment analysis dea decomposing labour productivity into efficiency change technical change and capital accumulation the decomposition shows that most regions have fallen behind the production frontier in efficiency and that capital accumulation has had a diverging effect on the labour productivity distribution using bootstrapping methods the paper also accounts for the inherent bias and the stochastic elements in the efficiency estimation it is found that the relative ranking of the efficiency scores remains stable after the bias correction even after controlling for spatially correlated measurement errors and that the dea successfully identifies the regions on the production frontier as significantly more efficient than other regions enfl

efficiency of educational production an analysis of new york school districts theoretical consideration of technical efficiency has existed since tjalling c koopmans 1951 which defined technical efficiency for production possibilities for which it is impossible to increase any output without simultaneously increasing any input the nonparametric approach to efficiency estimation is based not on this definition but rather on michael j farrell s 1957 index even after farrell efficiency is achieved there may exist additional slack in individual inputs implying that farrell efficiency doesn t measure inefficiency to solve this problem this paper suggests incorporating programming results into a second stage multivariate regression analysis for illustrative purposes this technique is applied to analyze new york state school districts copyright 1996 by mit press

growth and convergence of the oecd countries a multi sector production frontier approach abstract kumar and russell 2002 henderson and russell 2005 and badunenko henderson and russell 2013 have proposed a production frontier methodology to analyze the economic growth and the convergence of growth rates across countries they see two main advantages to this methodology 1 it reconstructs the world production frontier without relying on any particular typically unverifiable assumptions on any aspects of the growth process and 2 it allows to decompose labor productivity growth into several parts in this paper i extend the previous approach by considering a multi sector setting this setting allows to propose a more realistic and complete country level analysis while keeping the same advantages as with the previous methodology i also tackle the criticism of less reliable data at the sector level than at the country level by showing how the multi sector approach can easily be adapted i apply it to the oecd countries from 1995 to 2008 the results confirm the non neutrality of technological change i also find that capital accumulation plays the biggest role in the increase of output labor productivity while technological change and human capital accumulation also play an important role but it is twice as small as capital accumulation interestingly these results suggest the emergence of two groups eastern and central european countries and the eu15 and korea the two groups seem to diverge over time

teaching to the rating school accountability and the distribution of student achievement this paper examines whether minimum competency school accountability systems such as those created under no child left behind influence the distribution of student achievement because school ratings in these systems only incorporate students test scores via pass rates this type of system increases incentives for schools to improve the performance of students who are on the margin of passing but does not increase short run incentives for schools to improve other students performance using student level panel data from texas during the 1990 s i explicitly calculate schools short run incentives to improve various students expected performance and i find that schools do respond to these incentives students perform better than expected when their test score is particularly important for their schools accountability rating also low achieving students perform better than expected in math when many of their classmates math scores are important for the schools rating while relatively high achieving students do not perform better distributional effects appear to be related to broad changes in resources or instruction as well as narrowly tailored attempts to improve the performance of specific students
