is the secularization hypothesis valid a panel data assessment for taiwan the secularization thesis is based on the idea that a country becomes more secular as it becomes richer and more industrialized in order to investigate whether this hypothesis is valid we examine the relationship between religion in taiwan and economic development across 23 counties by adopting the panel data approach for the period 1998 to 2003 we select six religious activity proxy variables and five economic development variables in a cross county panel data framework the evidence indicates that the ratio of females to males has a significantly positive effect and that the literacy rate and population density each have a significantly negative effect on the religious variables finally except for the christian culture the unemployment rate has a positive effect on the religious variables our findings thus support the view that the religious secularization hypothesis is valid in taiwan

total factor carbon emission performance of the chinese transportation industry a bootstrapped non radial malmquist index analysis this paper proposes a non radial malmquist co2 emission performance index nmcpi for measuring dynamic changes in total factor co2 emission performance over time this index enables the consideration of non radial slacks in the conventional malmquist co2 emission index mcpi the nmcpi is calculated based on a non radial directional distance function derived by several data envelopment analysis dea models furthermore nmcpi could be decomposed into an efficiency change ec index and technological change tc index a bootstrapping approach is conducted to introduce statistical inferences into the nmcpi and its decompositions based on the proposed indices the dynamic co2 emission performance change and its decompositions of the chinese regional transportation industry from 2002 to 2010 are investigated the empirical results demonstrate that the total factor carbon emission performance of the transportation industry as a whole decreased by 32 8 over the period and this reduction was primarily caused by technological decline

estimating the bias in technical change a nonparametric approach in this note we propose a nonparametric methodology to estimate the bias in technical change we apply the model to estimate the direction of technical progress for a sample of 81 countries covering the period 1970 2014 our results confirm previous findings that during the 1980s technical change in industrialized countries has become increasingly capital using moreover we find that patterns in the bias of technical change have converged among different country groups after the productive decade 1995 2004

determining discount rates for the evaluation of natural assets in land use planning an application of the equivalency principle one of the most pressing issues when making decisions over long term environmental problems is deciding on an appropriate discount rate this can be a highly technical discussion while some argue in favour of market rates which usually tend to be high others support the use of near zero rates to ensure that both current and future generations are properly accounted for this paper presents an alternative approach to determining the discount rate for environmental assets in the case of land use planning the equivalency principle ep based on the normative proposition that the social value of protected natural land should be at least the same as the market price of an adjacent land with similar environmental characteristics that has been granted permission for development the paper first provides a theoretical overview of the approach followed by an application of the ep at the land plot level across 11 european countries based on the ep pure rates of social time preference that would equate natural and development land values within each administrative unit have been calculated the findings show that the application of the ep usually results in discount rates that are lower than market rates and that are geographically differentiated this implies discount rates that account for preferences of the society where the land or natural resource is located with results ranging between 0 and 11 with an average rate of 1 across study sites

are church and state substitutes evidence from the 1996 welfare reform abstract churches provide community services similar to those provided by the government but there has been no convincing analysis of the extent to which church activity can substitute for government activity to address this important issue this paper uses a new panel data set of presbyterian church usa congregations to regress both church member donations and a church s community spending on a number of variables including government welfare expenditures a provision of the 1996 welfare law that decreased the availability and use of welfare services by non citizens serves as an instrument to identify the causal effect of government spending on church activity the results show that church activities substitute for government activities extrapolating the findings to all denominations the estimated crowd out effect lies between 20 and 38 cents on the dollar the results are subjected to a number of robustness tests

the equivalency principle for discounting the value of natural assets an application to an investment project in the basque coast making decisions about optimal investments in green infrastructure necessitates setting social discount rates this paper suggests a practical way for determining the discount rate for projects or programmes in which one of the options is to maintain or improve land in its natural state we propose an a equivalency principlea to derive a simple rule that sets the discount rate the rule is based on the premise that the long term value of a naturally preserved land track ought to be at least the same as the value of an identical land track in the vicinity to which permission has been granted for development we illustrate this principle with various case studies and we apply it to a contentious investment project in the basque country associated with the regeneration of a large scale harbour in the province of gipuzkoa north of spain that involves reclaiming natural land that has important ecological value including for the conservation of a marine ecosystem

productivity growth and biased technological change in hydroelectric dams abstract this paper analyses productivity growth and the nature of technical change in a sample of portuguese hydroelectric generating plants over the period 2001 to 2008 in a first step we employ the luenberger productivity indicator to estimate and decompose productivity change a malmquist productivity index is also used for a comparative purpose the results paint a picture of mixed productivity performance in the portuguese energy sector the first decomposition underlines that in average the productivity variation is explained by the technological change then in a second step we analyse the nature of this technical change by using the recent concept of parallel neutrality briec et al 2006 we observe a global shift in the best practice frontier as well as in the evidence of input bias in technical change

sacrifice and stigma reducing free riding in cults communes and other collectives this paper presents an economic analysis of religious behavior that accounts for the continuing success of groups with strange requirements and seemingly inefficient prohibitions the analysis does not presuppose any special motives for religious activity rather religion is modeled as a club good that displays positive returns to participatory crowding the analysis demonstrates that efficient religions with perfectly rational members may benefit from stigma self sacrifice and bizarre behavioral restrictions the model also addresses sacrifice in nonreligious social clubs fraternities communes political parties work groups and families

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

total factor productivity and the measurement of technological change tfp is interpreted in the literature in different mutually contradictory ways changes in tfp are shown to measure not technological change only the super normal returns to investing in such change returns that exceed the full opportunity cost of the activity thus in the limit technological change can proceed with unchanged tfp measuring the effects of technological change instead requires counterfactual estimates reasons why changes in tfp are imperfect measures of super normal returns are also studied reasons connected with the timing of output responses the treatment of r d in the national accounts the omission of resource inputs and two types of aggregation la productivite totale des facteurs et la mesure du changement technologique la productivite totale des facteurs ptf est interpretee dans la litterature de manieres differentes et mutuellement contradictoires on montre que les changements dans la ptf ne mesurent pas le changement technologique mais seulement les rendements supra normaux sur les investissements dans de tels changements des rendements qui depassent le plein cout d opportunite de cette activite donc a la limite le changement technologique peut proceder sans que la ptf change mesurer les effets du changement technique reclame des evaluations d hypotheses de rechange les raisons pour lesquelles les changements dans la ptf sont des mesures imparfaites des rendements supra normaux sont aussi etudiees raisons connectees avec la reponse des niveaux de production le traitement de la r d dans les comptes nationaux l omission des intrants de ressources et deux types d agregation

has china s fast industrial growth been efficient an industry level investigation with a newly constructed data set we adopt contemporaneous nonradial and variable returns to scale assumptions in a data envelopment analysis dea exercise to address the inefficiency problem in chinese industries in different policy regimes using a newly constructed data set for 24 chinese manufacturing industries in 1952 2008 while confirming that the central planning period was indeed a graveyard for productivity that entailed severe technical regress and efficiency losses we do not find a steady improvement in efficiency during the reform period despite strong technical progress we argue that the resurgent prominence of the government and the state sector since the late 1990s especially following china s world trade organization accession has obstructed the efficiency improvement

exploring the green total factor productivity of china s metallurgical industry under carbon tax a perspective on factor substitution abstract the characteristics of high emissions and high energy consumption in metallurgical industry have brought great challenges to the green and low carbon transition in china as a low carbon economic instrument carbon tax is generally considered to be an effective way to reduce co2 emissions through raising energy cost but whether it will promote the green total factor productivity gtfp of china s metallurgical industry is still unanswered under this background this paper uses provincial panel data over years 2000 2015 to investigate the impact of carbon taxation on gtfp of metallurgical industry from the perspective of inter fuel and inter factor substitution the lock in mechanism is also incorporated in the three stage estimation model to better reflect the asymmetric price response of factors and fuels the results reveal that the slow marketization process of energy price and the rigid demand for energy in china s metallurgical industry hinder the substitution effect of energy the implementation of carbon tax has limited effect on energy saving and co2 reduction in the metallurgical industry of china and levying a carbon tax has a negative effect on gtfp during the research period therefore the government should not achieve co2 reduction targets at the expense of green economic growth gtfp is suggested to be considered in future assessment criteria in the process of transforming to low carbon economy

foreign direct investment spillovers and technical efficiency in the indonesian pharmaceutical sector firm level evidence the spillovers of foreign direct investment fdi on domestic firms performances have been highly debated for many years this article contributes to this debate by analysing spillovers effects on technical efficiency of indonesian pharmaceutical sector using a unique unbalanced panel of highly disaggregated at five digit international standard industrial classification isic 210 firms over the period 1990 1995 1001 observations the stochastic production frontier spf and the data envelopment analysis dea based on malmquist productivity indices mpi have been used to test the spillovers effects of fdi on technical efficiency the empirical results from the spf show that foreign firms are more efficient than domestic competitors and the presence of the former increases the inefficiency of the latter similarly the results from the mpi demonstrate that fdi has a negative and significant impact on technical efficiency changes in domestic competitors but generate positive spillovers to domestic s

valuing non market wildlife commodities an evaluation and comparison of benefits and costs this paper compares the benefits and costs of nature conversation at three sites of special scientific interest benefits are estimated by contigent valuation expressed preferences and also the travel cost method revealed preferences oppurtunity costs are assessed from a financial cost viewpoint and also in terms of shadow prices or social costs results indicate that the valuation of wildlife and nature conservation largely depends upon the frame of reference adopted that social costs are considerably less than financial costs due to the effect of the common agricultural policy that user benefits are considerably less than financial costs and non user benefits must be included to cover even the social costs of nature conservation

regional low carbon economy efficiency in china analysis based on the super sbm model with co2 emissions abstract as the largest energy consumer and co 2 emitting country the chinese government is committing to a low carbon economy it is meaningful and contributes to evaluate and analyze the low carbon economy efficiency lcee of china a super slack based measure super sbm model with undesirable outputs as combined with the malmquist productivity index is proposed to measure the lcee and the dynamic low carbon economy efficiency dlcee of 30 provinces in mainland china from 2005 to 2012 the theil index is also used to measure the rationalization level of industrial structure rlis for discussing the improvements to the lcee in china the results indicate that the proposed undesirable outputs super sbm model can effectively rank the sbm ef cient provinces china s regional economic development does not follow a low carbon pattern with an average lcee of 0 517 as a whole the china s economic development is gradually following a low carbon development pattern with an annual lcee improvement of 4 5 the rlis of china is also gradually changing better as well through a comparative analysis of the lcee and rlis the 30 provinces are divided into three sub areas and relevant suggestions are presented for improving the lcee of different sub areas in the future

multi period efficiency and malmquist productivity index in two stage production systems abstract conventional two stage data envelopment analysis dea models measure the overall performance of a production system composed of two stages processes in a specified period of time where variations in different periods are ignored this paper takes the operations of individual periods into account to develop a multi period two stage dea model which is able to measure the overall and period efficiencies at the same time with the former expressed as a weighted average of the latter since the efficiency of a two stage system in a period is the product of the two process efficiencies the overall efficiency of a decision making unit dmu in the specified period of time can be decomposed into the process efficiency of each period based on this decomposition the sources of inefficiency in a dmu can be identified the efficiencies measured from the model can also be used to calculate a common weight global malmquist productivity index mpi between two periods in that the overall mpi is the product of the two process mpis the non life insurance industry in taiwan is used to verify the proposed model and to explain why some companies performed unsatisfactorily in the specified period of time

sectoral change catching up and slowing down oecd post war economic growth revisited abstract regression analysis of gdp growth since 1950 on pooled oecd cross sections indicates uniform technological catch up in all sectors but lower marginal labour productivity in agriculture the decline in opportunities to reallocate labour explains some of the post 1973 productivity slowdown

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

regional energy efficiency carbon emission performance and technology gaps in china a meta frontier non radial directional distance function analysis abstract at present china is the largest primary energy consumer and carbon emitter in the world meantime china is a large transitional economy with significant regional gaps against such backgrounds the calculated results of energy and carbon performance indicators may be biased without considering heterogeneity across regions to this end after incorporating region heterogeneity this paper provides detailed information regarding energy efficiency carbon emission performance and the potential of carbon emission reductions from regional perspectives which may be important and useful for policy makers our main findings are as follows firstly there is significant group heterogeneity across regions in china in terms of energy efficiency and carbon emission performance secondly there are no considerable differences between total factor and single factor performance indices since there is limited substitutability between energy inputs and other production inputs finally significant carbon emission reductions can be made by catching up for regions with low energy efficiency and carbon emission performance looking ahead the chinese government should adopt measures to promote improvements in terms of energy efficiency and carbon emission performance in the short term

the impact of environmental expenditures on performance in the u s chemical industry abstract this study analyzes chemical industry companies with environmental expenditures to determine which ones have better financial performance in addition this study uses data envelopment analysis to evaluate the efficiency of firms with and without environmental expenditures this study also utilizes the malmquist productivity index mpi to analyze firms productivity change and a bootstrap method to test whether the indexes are statistically significant finally this study divides chemical industry companies into three main categories based on their products the results of this study provide significant evidence of a relationship between environmental expenditures and financial performance the findings suggest that firms with environmental expenditures have better efficiency and productivity hence the study encourages companies in the industry to put more effort into protecting the environment that can be through practicing cleaner production to create higher benefits

the role of environmental factors in growth accounting this paper explores a relatively new methodology the directional distance function method to analyse productivity growth the method allows us to explicitly evaluate the role that undesirable outputs of the economy such as carbon dioxide and other greenhouse gases have on the frontier production process which we specify as a piecewise linear and convex boundary function we decompose productivity growth into efficiency change catching up and technology change innovation we test the statistical significance of the estimates using recently developed bootstrap methods we also explore implications for growth of total factor productivity in the oecd and asian economies copyright 2004 john wiley sons ltd

on modeling and interpreting the economics of catastrophic climate change with climate change as prototype example this paper analyzes the implications of structural uncertainty for the economics of low probability high impact catastrophes even when updated by bayesian learning uncertain structural parameters induce a critical tail fattening of posterior predictive distributions such fattened tails have strong im plications for situations like climate change where a catastrophe is theoretically possible because prior knowledge cannot place sufficiently narrow bounds on overall damages this paper shows that the economic consequences of fat tailed structural uncertainty along with unsureness about high temperature damages can readily outweigh the effects of discounting in climate change policy analysis

productivity change technical progress and relative efficiency change in the public accounting industry we present evidence on components of productivity change in the public accounting industry toward the end of the 20th century using revenue and human resource data from 64 of the 100 largest public accounting firms in the united states for the 1995 1999 period we analyze productivity change technical progress and relative efficiency change over time the average public accounting firm experienced a productivity growth of 9 5 between 1995 and 1999 we find support for the hypothesis that technical progress rather than an improvement in relative efficiency was the reason for this productivity growth firms that were early movers into management advisory services mas and those that emphasized growth in mas over growth in the traditional audit and tax services enjoyed significantly higher productivity growth than their peers these firms also contributed significantly more to the industry s technical progress

eco efficiency of the western taiwan straits economic zone an evaluation based on a novel eco efficiency model and empirical analysis of influencing factors abstract obtaining the most economic benefits while using the least resources and causing the least environmental damage is an urgent and key problem in achieving sustainable development the concept of eco efficiency provides a comprehensive perspective for observing and solving this problem this paper proposes an extended data envelopment analysis model named the win us sbm as a comprehensive eco efficiency evaluation method that can accommodate undesirable outputs all the identification problems of decision making units dmus possible slacks of variables and the problems of an insufficient number of available dmus and intertemporal comparability china s western taiwan straits economic zone wts economic zone is an important regional economic growth center by applying win us sbm and arcgis software we investigated data on the temporal and spatial evolution characteristics of eco efficiency in the wts economic zone for the years 2009 2016 later the global malmquist luenberger index was used to decompose the sources of growth in eco efficiency finally the main driving factors of eco efficiency were explored through a tobit regression analysis the empirical results show that 1 the overall eco efficiency of the wts economic zone had greatly improved increasing by 11 46 annually and the cumulative growth rate of eco efficiency was 110 84 from 2009 to 2016 2 the eastern area had the highest average eco efficiency followed by the western area and the middle area in that order also the growth rate of the middle area ranked first 16 68 whereas the eastern area had the slowest growth in eco efficiency 7 22 3 on the whole the growth of eco efficiency was driven mainly by technological progress and was restricted by the decrease in management level which implies that policy makers should focus on improving management and technical levels 4 high levels of economic development population density market openness and industrial structure had positive effects on the eco efficiency of the wts economic zone whereas energy intensity and expenditure on science and technology had negative impacts

radial and non radial decompositions of profit change with an application to indian banking abstract grifell tatje and lovell grifell tatje e lovell c a k 1999 profits and productivity management science 45 1177 1193 made significant contributions to the literature on the extended radial dea framework by decomposing profit change into six mutually exclusive components their approach however poses two basic problems first the radial estimates on these components might give conflicting signals about the direction of profit change after the full radial efficiencies are achieved when slacks are present second evaluations of these components using base period prices as weights can be potentially misleading to address these concerns we first introduce non radial dea models and then provide a few strong theoretical arguments in favor of using as weights either current period prices or an average price covering both periods to value the contributions of each of these components the indian banking sector is taken as a case study to illustrate the radial and non radial decompositions of profit change so as to empirically examine the role of competition on profit change and its drivers our broad empirical results are as follows first radial and non radial models yield diametrically opposite results on the contributions of various components second the increasing efficiency change trends in all ownership groups after 2002 indicate that the government reform process instituted on the banking industry has had a favorable effect on the performance of the indian banking sector third despite the fact that nationalized banks are the oldest banks their output and resource allocation behaviors do not reflect their learning experience

decomposition of the fisher ideal index of productivity a non parametric dual analysis of us airlines data in this paper we offer a non parametric method of decomposing the fisher ideal index of productivity into individual factors measuring i technical efficiency change ii allocative efficiency change iii shift in the cost function iv scale economies due to output change and v an adjustment factor reflecting change in the output attributes cross section data from the us airline industry for the years i 983 and i 984 are utilised in an empirical application illustrating this method the rate of multifactor productivity growth mfpg over time in the single output multiple input case can be measured by the difference in the rates of growth in the quantity of output and the divisia index of input quantity when no technical inefficiency exists this rate of mfpg can be decomposed into two additive components i the rate of technical change measuring the rate of change in the volume of output holding the input bundle unchanged and ii a returns to scale effect showing change in productivity with changes in the input quantities without technical change when technical efficiency varies over time a part of the measured rate of mfpg would be due to efficiency

assessing productivity changes in uk hospitals reflecting technology and input prices in this study malmquist productivity indexes are used to evaluate the performance of acute hospitals in the uk over the period after the introduction of the internal market in the national health service in 1991 the indexes are computed using nonparametric programming known as data envelopment analysis and they are decomposed into multiple component measures to give insights into the trends in hospital performance overall it is found that productivity regressed in the year after the reforms but progressed thereafter so that overall there was a net progress both as far as the inputs and costs are concerned productivity progress is mainly due to overall efficiency progress which in turn is mostly attributed to allocative efficiency improvements technical change resulted in a small reduction in the amount of inputs used but also at higher production costs because of a worsening in the match between input mixes and relative input prices however it is suggested that the gains in productivity are not

analyzing components of productivity growth using the bennet lowe indicator an application to welsh sheep farms this article introduces the bennet lowe total factor productivity tfp indicator the proposed measure is difference based additively complete and transitive we also develop a general nonparametric framework to exhaustively decompose all bennet type tfp indicators including the one introduced here into technical change technical efficiency change scale efficiency change and mix efficiency change this decomposition provides a powerful tool for policy makers to guide financial decisions on research and development extension subsidies and price support the empirical application focuses on the welsh sheep sector for the years 2001 2014 the results show that in this 14 year period welsh sheep farms increased their tfp by 30 28 on average 2 33 p a however the exhaustive decomposition shows that tfp growth is not distributed equally across all farms with an increasing divergence between front runners and laggards the negative values of scale efficiency change and mix efficiency change cast doubt on the current subsidy policies

privatization of nippon telegraph and telephone was it a good policy decision nippon telegraph and telephone ntt corporation was privatized in 1985 under the economic assertion that a public enterprise is less efficient and less profitable than a private enterprise this assertion is referred to as the property right theory in economics and it is used as a theoretical rationale for privatizing publicly owned organizations this article empirically examines the economic assertion by comparing ntt s performance before and after its privatization data envelopment analysis dea is used as the research tool in this study which confirmed the economic assertion in terms of production based efficiency measures but it cannot find any major difference in its cost reducing corporate efforts thus this study presents serious management problems occurring within the ntt s partial privatization the partial privatization is now prevailing in the telecommunications industry all over the world this article also discusses the japanese business environment which makes ntt managerially ineffective under its public private joint ownership

does renewable and or non renewable energy consumption matter for total factor productivity tfp growth evidence from the brics abstract studies proved that output growth is mainly associated with the total factor productivity tfp growth and variables that affect the tfp have an important explanatory power on output in this regards the aim of this study is to examine the causal relationship between different types of energy consumption and tfp growth in the brics from 1992 to 2012 a panel bootstrap granger causality test by konya 2006 68 was employed to investigate the direction of possible connection between energy consumption and tfp growth results show that no remarkable causal link exists between renewable energy consumption and tfp growth in the brics however in the case of non renewables energy consumption creates a positive externality that contributes economic development in brazil and south africa by the growth of tfp as well as energy use itself in this respect policies that promote coal and non renewable electricity consumption in south africa and natural gas consumption in brazil may be beneficial for their economic development

ethics of the discount rate in the stern review on the economics of climate change any comparison of the costs and benefits of climate change is dominated by the chosen discount rate but although the stern review emphasises the ethical nature of the parameters entering into its choice of a relatively low discount rate its discussion of the pure time preference parameter is unbalanced in particular no consideration is given to the role of agent relative ethics which i has a wellestablished philosophical pedigree going back to david hume ii is likely to correspond closely to world wide public attitudes towards intergenerational welfare and iii would entail discounting a unit of welfare accruing to future generations compared to an equal unit accruing to people alive today at a positive rate the authors also discuss the other ethical parameter upon which the discount rate depends namely the elasticity of marginal utility with respect to consumption in the conventional model this simultaneously reflects different aspects of inequality aversion as well as risk aversion which complicates its interpretation finally they discuss the divergence between market rates of discount and the low rate chosen in the review and the limitations on the one hand on the normative significance of market rates as well as the danger on the other hand of relying on rates chosen by elites or philosopher kings

religious participation and income the relationship between religion and income has been explored in several studies in this paper we extend this inquiry by arguing that religious participation through its effects on preferences and net earnings potential reduces participants incomes similarly we argue that high incomes discourage religious participation by encouraging individuals to substitute market work for religious activities in an empirical model we simultaneously estimate the effects of religious participation on income and income on religious participation using us state data on per capita personal income and church membership the results strongly support our hypotheses 2002 elsevier science b v all rights reserved

modelling technical efficiency in cross sectionally dependent stochastic frontier panels summary this paper proposes a unified framework for accommodating both time and cross sectional dependence in modelling technical efficiency in stochastic frontier models by combining the exogenously driven factor based approach and an endogenous threshold efficiency regime selection mechanism this approach is able to deal with both weak and strong cross sectional dependence in a flexible manner using a dataset of 26 oecd countries over 1970 2010 we provide satisfactory estimation results for the production technology parameters and the associated efficiency ranking of individual countries we find a positive spillover effect on efficiency supporting the hypothesis that knowledge spillover is more likely to be induced by technological proximity furthermore our approach enables us to identify efficiency clubs endogenously

total factor productivity measurement and human capital in oecd countries abstract this paper analyses the total factor productivity tfp evolution in oecd countries by breaking down productivity gains into technical change and efficiency change to avoid biases malmquist indices of productivity including human capital are estimated the results indicate that in fact the inclusion of human capital has a significant effect on the accurate measurement of tfp

introduction to the economics of religion after a very long hiatus economists have begun again to study the relationship between economics and religion this article seeks to summarize and evaluate the principal themes and empirical findings that have appeared in some 200 recent papers on the economics of religion although some of the research concerns the economic consequences of religiosity most applies standard economic theory to the study of individual religious activity the characteristics of religious groups and the impact of regulation and competition on religious markets

is there a slowdown in agricultural productivity growth in south america this article estimates agricultural productivity growth in 10 south american countries in 1969 2009 with the objective of investigating if the slowdown being measured in other countries is present in the region results show that productivity growth accounts for half of the three fold increase in agricultural output during this period and that performance is sensitive to r d investments in the sector the slowdown found for the 1990s to 2000s in the u s and some european economies does not seem to be present yet in south america the region s total factor productivity tfp growth rate increased steadily from 1 07 during the 1970s to 2 29 during the 2000s given lags in adoption and the adaptive nature of innovations in these economies we have yet to see the potential effects in south american agriculture of decreases in r d in advanced economies

measuring the efficiency of digital convergence abstract the paper suggests the use of data envelopment analysis dea and malmquist productivity index for keeping up with the trends in digital economy development effectiveness in the european countries we show that central and eastern europe countries converge to the eu average concerning the level of digital economy development while digital divide exists between the eu and the western balkan countries

the effect of incentive reforms upon productivity evidence from the vietnamese rice industry in this study we use region level panel data on rice production in vietnam to investigate total factor productivity tfp growth in the period since reunification in 1975 two significant reforms were introduced during this period one in 1981 allowing farmers to keep part of their produce and another in 1987 providing improved land tenure we measure tfp growth using two modified forms of the standard malmquist data envelopment analysis dea method which we have named the three year window tyw and the full cumulative fc methods we have developed these methods to deal with degrees of freedom limitations our empirical results indicate strong average tfp growth of between 3 3 and 3 5 per cent per annum with the fastest growth observed in the period following the first reform our results support the assertion that incentive related issues have played a large role in the decline and subsequent resurgence of vietnamese agriculture

preaching matters replication and extension statistical evidence in a recent excellent paper by lipford mccormick and tollison shows a negative relationship between church membership and social misbehavior this paper replicates that relationship using more comprehensive data by u s county we provide theoretical support for the statistical evidence by showing that churches encourage appropriate behavior thus providing property rights enforcement because doing so benefits churches and their members aa church membership increases property rights enforcement increases although at a diminishing rate

contingent valuation and social choice the contingent valuation method for estimating the existence value of natural resources is examined for psychophysical robustness statistical reliability and economic sensibility extensions of standard models for willingness to pay and suitable econometric techniques for analyzing these models are developed the analysis is applied to a series of experiments on the value of preserving wilderness areas in the western united states the results call into question the reliability of the cv method for estimating existence values

technical efficiency and productivity analysis in indonesian provincial economies this article estimates inefficiency and total factor productivity tfp across indonesian provinces from 1993 to 2000 indonesia is a large emerging market economy but provinces within the country due to the island structure of the country are more distinct from one another compared to other countries we use a stochastic frontier methodology to estimate inefficiency and tfp we find that tfp fell by an average rate of 7 5 across provinces due to the decrease in technical efficiency in fact the majority of output growth within indonesia is explained by the accumulation of inputs in this sense economic growth within indonesia does not appear to be sustainable without reversing these trends

malmquist productivity indexes and fisher ideal indexes comment fare and grosskopf i992 henceforth abbreviated as fg showed that under some conditions the productivity index defined as the geometric mean of two input based malmquist productivity indexes is equal to the quotient of the fisher input quantity index and the fisher output quantity index both fisher indices can be computed from observed prices and quantities these conditions appear to be so strong that they will almost certainly never be fulfilled in practice this is shown by a careful inspection of fg s proof however under slightly milder but more plausible conditions it can be shown that the quotient of the fisher input index and the fisher output index is a reasonable approximation of the productivity index consider a firm at two time periods t o i with different technologies which are modelled by the input correspondences lt y x x can produce y x c rn yce rm it is assumed that the sets lt y are closed and convex and that inputs are strongly disposable the vectors x yt wt pt t o i denote observed inputs observed outputs observed input prices and observed output prices respectively the productivity index is defined as

searching for sustainability the poverty of spontaneous order abstract traditional approaches to sustainability rely on models that depend upon judgments of welfare across future generations right prices and some sense as to what future persons will find giving of utility these models both accept the spontaneous order of market processes and rely on that order to derive optimal consumption paths into the future sustainability is however not a problem of divining optimal paths predicated upon right prices rather sustainability to be operational requires a prior constructed order predicated upon rights for future persons and duties for those now living who sit in a position as dictator over the settings and circumstances that will be passed on to future persons rights based approaches to sustainability do not rely upon unknowable preferences of future persons but rather upon an environmental regency in which those now living agree to preserve settings and circumstances for the future this reminds us that the issue of sustainability concerns not how much to preserve but what to preserve

sources of productivity growth using the fare primont decomposition an empirical application to the irish beef sector several competing methodologies for tfp estimation have been developed in the past decades a popular approach in the literature is index number computation the most widely implemented tfp indices

economic efficiency and frontier techniques abstract most of the literature related to the measurement of economic efficiency has based its analysis either on parametric or on non parametric frontier methods the choice of estimation method has been an issue of debate with some researchers preferring the parametric and others the non parametric approach the aim of this paper is to provide a critical and detailed review of both core frontier methods in our opinion no approach is strictly preferable to any other moreover a careful consideration of their main advantages and disadvantages of the data set utilized and of the intrinsic characteristics of the framework under analysis will help us in the correct implementation of these techniques recent developments in frontier techniques and economic efficiency measurement such as bayesian techniques bootstrapping duality theory and the analysis of sampling asymptotic properties are also considered in this paper

using a choice experiment to account for preference heterogeneity in wetland attributes the case of cheimaditida wetland in greece abstract this paper aims to assist policy makers in formulating efficient and sustainable wetland management policies in accordance with the ramsar convention and the european union water framework directive 2000 60 ec by providing results of a valuation study on the cheimaditida wetland in greece a choice experiment is employed to estimate the values of changes in several ecological social and economic functions that cheimaditida wetland provides to the greek public in addition to the conditional logit model a random parameter logit model a random parameter logit model with interactions and a latent class model are estimated to account for heterogeneity in the preferences of the public for the various functions of the wetland the results reveal that there is considerable preference heterogeneity across the public and on average they derive positive and significant values from sustainable management of this wetland the estimated economic benefits of sustainable wetland management are weighed against the costs of alternative wetland management scenarios results of this cost benefit analysis can aid in the design of socially optimal policies for sustainable management of the cheimaditida wetland with possible implications for other similar wetlands in greece and the rest of europe

eco efficiency change in power plants using a slacks based measure for the meta frontier malmquist luenberger productivity index abstract malmquist luenberger index is a popular index deployed for evaluating eco efficiency and productivity change over a certain period when both desirable and undesirable factors are jointly produced in some production processes however conventional data envelopment analysis dea models used for computing this index are unable to distinguish the various technologies employed by the decision making units when heterogeneity exists in the technology the meta frontier malmquist luenberger approach is adopted to evaluate eco efficiency and productivity change over a period when undesirable outputs are incorporated in the analysis of efficiency in this paper a new slacks based dea measure is developed and used to compute the meta frontier malmquist luenberger productivity index this approach is then deployed to evaluate 48 iranian thermal power plants productivity change in three different categories steam gas and combined cycle over an eight year period of restructuring in the power industry this technique enables the calculation of eco efficiency change of thermal power plants operating under different technologies as well as the technology gap ratios and measures the extent to which the efficiency frontiers of individual categories of power plants deviate from the meta frontier the results reveal that the last years of the restructuring period saw a greater rate of productivity growth compared to the initial years and evidence of significant eco efficiency improvements over the period in all the three types of the thermal power plants finally it is expected that the findings in this study aid policy makers and power industry regulators in developing sustainable energy policies towards environmental protection and planning power plant operations

sustainability performance for china s transportation industry under the environmental regulation abstract traffic and transportation industry is a carbon intensive industry in china the implementation of environmental regulation is of important practical significance nowadays literatures lack of quantitative analysis on transport industry s sustainability performance under the environmental regulation by using a directional distance function this paper aims to investigate the effect of environmental regulation on this industry furthermore this paper measures its green total factor productivity under the general intensity of regulation and strict regulation from 2000 to 2010 results show that the economic growth mode in transportation industry is still the extensive mode while there is great potential for the improvement of energy saving and production

bridging the gap between partial and total factor productivity measures using directional distance functions technical dependencies as well as data constraints limit our ability to allocate inputs across sectors and hence our ability to measure sectoral productivity we adapt a directional measure of efficiency to the measurement of sector specific productivity that does not require allocating all inputs across sectors applied to the agricultural sector of a group of countries the results show important differences in livestock and crops productivity growth commonly used partial factor productivity measures for livestock and crops tend to overestimate productivity growth in most developing countries while underestimating it in european countries

the relationship between the income elasticities of demand and willingness to pay abstract the relationship between income and willingness to pay for collectively provided public environmental goods is investigated we show that while the income elasticity of willingness to pay and the ordinary income elasticity of demand are related knowledge of one is insufficient to determine the magnitude or even the sign of the other the income elasticity of willingness to pay is influenced by additional factors which are generally unobservable examples are provided to illustrate the degree to which the two income elasticities may diverge our results indicate that even when goods are demand luxuries they may or may not have income elasticities of willingness to pay which are greater than one

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

a review of the stern review on the economics of climate change how much and how fast should we react to the threat of global warming the stern review argues that the damages from climate change are large and that nations should undertake sharp and immediate reductions in greenhouse gas emissions an examination of the review s radical revision of the economics of climate change finds however that it depends decisively on the assumption of a near zero time discount rate combined with a specific utility function the review s unambiguous conclusions about the need for extreme immediate action will not survive the substitution of assumptions that are consistent with today s marketplace real interest rates and savings rates

a non parametric analysis of productivity the case of u s and japanese manufacturing a nonparametric analysis of technology technical change and productivity is presented in the context of cost minimizing behavior a number of nonparametric tests concerning the existence and nature of technical change are applied to u s and japanese manufacturing data nonparametric measures of technical change are presented copyright 1990 by american economic association

efficiency and technical progress sources of convergence in the spanish regions the paper analyses the contribution of efficiency as a mechanism of labour productivity convergence taking as the unit of analysis the spanish regions in the period 1964 1993 using the stochastic frontier approach a translogarithmic production function is estimated for the different sectors of the spanish regional economy demonstrating on this basis the existence of substantial differences in efficiency between sectors as well as between regions with regard to convergence the results obtained indicate that at aggregate level the convergence observed in labour productivity is explained by the faster growth of the capital labour ratio of the initially poorer regions and the contribution of technical change and the efficiency hence by the convergence of tfp however the information by sectors shows different results thus on the one hand the importance of the convergence in production per employee is seen in all sectors except agriculture and on the other it is observed that technical change is a

performance and efficiency in colombia s power distribution system effects of the 1994 reform we assess evolution in performance efficiency and productivity of colombia s power distribution utilities before and after the 1994 regulatory reform that introduced electricity market activities for the power sector in 12 distribution companies from 1985 to 2001 performance is evaluated contrasting changes in mean and median by wilcoxon rank sum and pearson tests on financial and other performance indicators technical efficiency is measured by means of data envelopment analysis dea the nature of the dataset allows the estimation of malmquist productivity index and its evolution in time results show a recovery after the reform in the main performance indicators of profitability partial input productivity and output plant efficiency and productivity increased after the reform mainly in the largest utilities used as benchmarks in the dea efficiency scores measures meanwhile the less efficient power distribution companies did not improved after the reform and were not able to undertake plant restructuring to catch up in plant efficiency with respect to the pareto efficient input allocations econometric results on dea efficiency scores suggest a positive effect of policy reform

the evolution and main determinants of productivity in brazilian electricity distribution 1998 2005 an empirical analysis abstract this paper estimates changes in the productivity of the brazilian electricity distribution sector using data envelopment analysis dea on a panel of 18 firms from 1998 to 2005 the study decomposes the productivity change of these distribution firms in terms of technical efficiency scale efficiency and technical progress this exercise aims to help the understanding of the main determinants of the evolution of productivity focusing its relationship with the restructuring process implemented in the 1990s tfp index records a yearly positive growth rate of 1 3 in the whole period under analysis for all firms technical change was the main component behind this evolution with an average growth of 2 1 per year while technical efficiency presented a yearly negative performance of 0 8 the results prove that in general terms the incentives generated in the reform process do not seem to have led the firms to behave in a more efficient manner

total factor carbon emission performance of fossil fuel power plants in china a metafrontier non radial malmquist index analysis article i nfo this paper proposes the metafrontier non radial malmquist co2 emission performance index mnmcpi for measuring dynamic changes in total factor co2 emission performance over time the mnmcpi method allows for the incorporation of group heterogeneity and non radial slack into the previously introduced malmquist co2 emission performance index mcpi we derive the mnmcpi by solving several non radial data envelop ment analysis dea models we decompose the mnmcpi into an efficiency change ec index a best practice gap change bpc index and a technology gap change tgc index and based on the proposed indices we examine the dynamic changes in co2 emission performance and its decomposition of fossil fuel power plants in china for the 2005 2010 period the empirical results show a 0 38 increase in total factor co2 emission performance as a whole and a u shaped mnmcpi curve for the sample period because companies owned by the central government lack innovation and technological leadership the results suggest a missing link in the role of the central government in promoting co2 emission performance

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

estimations of the economic model of crime using aggregate and individual level data much has happened in the economics of crime since becker s 1 seminal paper of two decades ago the theory has been refined by among others ehrlich 10 11 12 block and lind 4 5 block and heinke 3 and schmidt and witte 30 attempts to test the model empirically began immediately the most cited including ehrlich 10 11 12 sjoquist 31 carr hill and stern 7 phillips and votey 26 witte 38 and myers 22 23 interest continues with recent work including layson 19 sandelin and skogh 29 ehrlich and brower 13 cover and thistle 9 viscusi 36 and tauchen witte and griesinger 33 there has been some controversy however concerning the type of data more suitable to the estimation of the economic model of crime most of the work has used aggregate data in which the unit of observation is a political jurisdiction but the use of aggregate data has been sharply criticized the alternative is individual data few attempts have been made to use individual data probably because an ideally constructed data set representative of a general population would be far too costly for most research budgets most of the studies that have been done have used data on releasees from prison or other criminal justice programs they are in effect recidivism studies based on the economic model of crime
