environmental efficiency and abatement efficiency measurements of china s thermal power industry a data envelopment analysis based materials balance approach abstract appropriate measurement of environmental and emission abatement efficiency is crucial for assisting policy making in line with constructing a more sustainable society the majority of traditional approaches for environmental efficiency measures take pollutant emissions as either undesirable outputs or environmentally determined inputs which suffer a limitation of not satisfying the physical laws that regulate the operation of economic and environmental process in this study we propose a dea based approach which is combined with the materials balance principle mbp that accounts for laws of thermodynamics to jointly evaluate environmental and abatement efficiency this approach is along the line of weak g disposability based modelling but is an extension to existing models that in our approach the identification of possible adjustments on polluting mass bound in inputs and outputs and potential adjustments on abatement of pollutants are all included the overall environmental efficiency measured by this approach is decomposed into the measures of technical efficiency polluting inputs allocative efficiency and polluting and non polluting inputs allocative efficiency with the emphasizing of incorporating pollutant abatement activities accordingly new measures of abatement efficiency are proposed which help to identify the pollutant abatement potential that can be achieved from end of pipe abatement technology promotion associated with polluting input quality promotion and input resources reallocation furthermore several global malmquist productivity indices for identifying the changes on environmental and abatement efficiency are proposed this approach is applied to china s thermal power industry and some empirical results verifying the necessity of introducing the mbp are obtained

weak disposability in nonparametric production analysis reply to fare and grosskopf fare and grosskopf this issue claim that a single abatement factor suffices for modeling weak disposability in nonparametric production models and that the kuosmanen 2005 technology that uses multiple abatement factors is larger than necessary this article demonstrates by a numerical example that a single abatement factor does not suffice to capture all feasible production plans and that its use leads to the violation of convexity one of the maintained assumptions of the model we also prove that the kuosmanen technology is the correct minimum extrapolation technology under the stated axioms

assessing regional eco efficiency from the perspective of resource environmental and economic performance in china a bootstrapping approach in global data envelopment analysis abstract eco efficiency has been receiving increasing attention across the world this paper proposes an extended data envelopment analysis model which combines global benchmark technology directional distance function and a bootstrapping approach to investigate the dynamic trends of regional eco efficiency in china from 2003 to 2014 moreover a developed slacks based measure is utilized to decompose the performance fluctuations into resource environmental and economic efficiency then the key factors responsible for the changes in eco efficiency are explored using the global malmquist luenberger index the empirical results demonstrate an upward trend of eco efficiency in china during the study period this trend was high in eastern and northern areas but low in northwestern areas however it should be noted that some eco efficient regions still consume much land water and energy and emit much environmental pollutants in absolute terms the whole of china performs well on the economic front while resource and environmental performances are not encouraging particularly on environmental efficiency the eastern and northern regions have experienced the greatest advances in both resource and environmental efficiency while the undeveloped areas have not shown much progress which further widens the gaps between developed areas and undeveloped areas the decomposition of productivity growth indicates that technical progress is the decisive factor in promoting china s eco efficiency while decreasing management level is the major obstacle hampering the improvement in eco efficiency

mixed strategy nash equilibrium in data envelopment analysis abstract in a typical productivity analysis the efficiency measure assumes a perfectly competitive market with an endogenous price and depends on a fixed orientation with respect to a specific firm such as an input oriented measure when an imperfectly competitive market affects the endogenous price however firms may take a mixed strategy approach to address uncertain competition this study proposes a mixed strategy measure msm we construct a model embedded with a data envelopment analysis dea framework that identifies the mixed strategy nash equilibrium in the first stage and considers a probabilistic and multi oriented efficiency measure in the second stage based on the environmental regulation and a typical nash measure we create two indices environmental consistency and strategic consistency to support the business roadmap development we validate the proposed msm with an empirical study of china s electric power industry the results find that the proposed msm complements the nash measure and the msm model successfully supports our two managerial strategies invest in capacity expansion or develop emission abatement technology

eco efficiency analysis of power plants an extension of data envelopment analysis abstract in public discussion on environmental policy the notion of eco efficiency is often used the joint production of goods and undesirable outputs such as pollutants which may not be freely disposable without costs causes difficulties to measure the overall performance of the firm because of the absence of market prices for the undesirable outputs we are not able to estimate the environmental costs some of the measurement and evaluation difficulties can be overcome by employing data envelopment analysis dea as the efficiency measurement vehicle we propose the use of two different approaches in the first approach we start by decomposing the problem into two parts 1 the problem of measuring technical efficiency as the relation of the desirable outputs to the inputs and 2 the problem of measuring so called ecological efficiency as the relation of the desirable outputs to the undesirable outputs separately those two efficiency indicators are then combined in the second approach we treat pollutants as the inputs in the sense that we wish to increase desirable outputs and decrease pollutants and inputs the approaches are applied to the problem of measuring the efficiency of 24 power plants in a european country

income inequality within and across counties in rural china 1988 and 1995 abstract using household data from samples covering 18 provinces in 1988 and 1995 income inequality within and between counties in rural china is assessed the approach enables us to aggregate average income and income inequality to the levels of provinces and the three regions comprising eastern central and western china most of income inequality in rural china in 1995 was found to be spatial and the uneven development of mean income across counties stood for most but not all of the rapid increase in income inequality mean income of the three regions diverged most forcefully

interaction between output efficiency and environmental efficiency evidence from the textile industry in jiangsu province china environmental efficiency improvement has played a crucial role in the theory and practice of stimulating clean production this paper analyzes the interaction between environmental efficiency and output efficiency particularly whether they reinforce each other or compete with each other on the basis of a data set of 137 firms in the textile industry in china s jiangsu province in the first stage generalized data envelopment analysis is applied to calculate efficiency measures of energy waste water waste gas soot and output efficiency taking capital labor water and energy as inputs industrial output value as desirable output and waste water discharges waste gas and soot emissions as undesirable outputs in the second stage analysis a structural equation model with latent variables is applied to analyze the interaction between the latent variable environmental efficiency measured by the four observed environmental indicators and output efficiency taking also into account the endogenous variable profit the main outcomes of the structural equation model are the following firstly environmental efficiency negatively impacts on profit while profit positively impacts on environmental efficiency in a similar vein output efficiency is found to depress profit while profit increases output efficiency thirdly environmental efficiency has a positive impact on output efficiency while there is no effect of output efficiency on environmental efficiency fourthly taxes impair a firm s output efficiency from the findings it follows that a swap of general taxes for an energy tax is likely to improve both output efficiency and energy efficiency the latter outcome implies a win win situation which will facilitate the further implementation and adoption of environmental policy finally the paper illustrates the applicability of structural equation modeling in efficiency analysis

returns to damage under undesirable congestion and damages to return under desirable congestion measured by dea environmental assessment with multiplier restriction economic and energy planning for social sustainability in china this study discusses the concept of natural and managerial disposability from their economic and methodological implications on social sustainability development then it explores their analytical linkages to a concept on congestion the concept is classified into undesirable congestion uc under natural disposability and desirable congestion dc under managerial disposability considering the two disposability concepts this study compares between returns to damage rtd under uc and damages to return dtr under dc conceptually uc and dc are conceptually different from rtd and dtr although they are closely related to each other group an occurrence of the former measures is identified by a single negative multiplier i e dual variable in contrast the latter measures are associated with multiple negative multipliers and an intercept of a supporting hyperplane on a production and pollution possibility set thus an occurrence of uc and dc is a necessary condition but not a sufficient condition on rtd and dtr respectively in terms of the number of negative multipliers on production factors to document the practicality of the proposed approach this study applies it to chinese economic and environmental assessment for its economic and energy planning for social sustainability development this study identifies four important findings first the chinese government has historically paid attention to the economic prosperity but not paying serious attention on the environmental pollution e g air pollution second there was an increasing trend in improving the two components i e economic and environmental performance measures regarding social sustainability third china s economic and energy policy concerns have been focused upon well developed municipalities e g beijing and shanghai and large provinces therefore it is an important strategy for the government to allocate economic and energy resources to other provinces so that china can reduce the industrial and regional imbalances as a result china can enhance the level of social sustainability finally the municipalities need strict regulation on traffic control in these metropolitan areas and a fuel mix shift from coal combustion to natural gas and renewable energies e g solar water and nuclear generations the fuel mix strategy along with the structure change e g from manufacturing to service and from public to private energy firms will be a major industrial policy issue for china in near future

a literature study for dea applied to energy and environment abstract this study systematically summarizes previous research efforts on data envelopment analysis dea applied to energy and environment in the past four decades including concepts and methodologies on dea environmental assessment industrial developments are very important for all nations in terms of their economic prosperities a problem is that the development produces various pollutions on air water and other types of contaminations all of which are usually associated with our health problems and climate changes thus it is necessary for us to consider how to make a balance between economic success and pollution mitigation to maintain a high level of social sustainability in the world it is widely considered that dea is one of the methodologies to examine the level of sustainability this study examines a recent research trend on dea applications from 1980s to 2010s nowadays many researchers have paid serious attention on how to combat various difficulties in the areas of energy and environment as a result the number of articles on dea applications on energy and environment has dramatically increased particularly after 2000s however it is true that dea has strengths and drawbacks in the applications therefore it is very important for us to carefully use dea for guiding large policy issues and business strategies such as the global warming and climate change an underlying premise of this study is that technology innovation in engineering and natural science may solve various problems by linking it with political and managerial efforts the use of dea provides a methodological linkage among them so enhancing the practicality in mitigating problems due to climate change and environmental pollutions this literature study along with a summary on conceptual and methodological developments provides us with guidelines for our future research works on dea on energy and environment issues

regional environmental efficiency in china an empirical analysis based on entropy weight method and non parametric models abstract while vigorously developing its economy china is attaching more and more importance to environmental protection and pollution control in different regions of china however there are great differences in economic development and the degree of environmental pollution in this study we use the entropy weight method to calculate the pollution indexes of different regions from 2015 to 2017 then we evaluate the chinese regional environmental efficiency based on a new non parametric frontier model moreover a new set of ranking interval models that treat the undesirable outputs as inputs is proposed to further describe the regional disparities of the environmental efficiency between different regions with robustness finally we conduct an empirical analysis by combining the stepwise regression and principal component analysis to identify the most influential variables that may affect regional environmental efficiency according to the results the southeast region of china performs best in environmental efficiency followed by the northeast region then the southwest region and the worst is the northwest region for managerial implications we find that the investment of high education and the development of the it industry can significantly increase regional environmental efficiency more importantly the results of the principal component analysis provide the government with a set of variables to strategically select the most appropriate strategy

structural change and the macroeconomic effects of oil shocks empirical evidence from the united states and japan abstract this paper investigates whether the usa and japan have become better insulated from oil price disturbances due to more favorable structural conditions new production technologies allowing greater energy substitution the development of energy commodity markets reduced energy intensity of production more market oriented energy policies and so on we decompose the influences of oil shocks on real gnp growth and inflation movements in the context of a simultaneous equation model where identification is partly achieved by restricting the long run dynamics we find that oil shocks accounted for a greatly reduced fraction of real gnp growth and inflation variance in both countries primarily because of superior insulation characteristics rather than reduced importance of oil disturbances our estimates suggest that a similar percentage oil price hike would have exerted about one quarter the contractionary effect on real gnp and upward push in inflation in the 1980s compared with the previous two decades jel e31 e32 f30

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

regional heterogeneity of china s energy efficiency in new normal a meta frontier super sbm analysis abstract this study aims at investigating regional heterogeneity of china s energy efficiency in the new normal a model combining meta frontier method and super sbm is proposed which has higher discriminatory power under the group frontier the energy efficiencies of the eastern central western and northeastern china and each provinces were estimated during 2006 2016 we also discussed the technology gaps of different regions the changes in energy efficiency and the main influencing factors of energy efficiency the results show that the highest energy efficiency lied in eastern china surprisingly the technology levels of central and western china have improved rapidly furthermore as china enters a new normal period more regions showed a strong decoupling relationship between energy consumption and economic growth meanwhile the regression results indicate that both state intervention and market openness had negative impacts on energy efficiency in different study periods finally according to the local conditions of different regions several policy recommendations to promote china s regional energy efficiency improvement are proposed

technical efficiency and impact of environmental regulations in farrow to finish swine production in taiwan this article demonstrates how technical efficiency and the impact of environmental regulations of taiwanese farrow to finish swine production can be estimated in the presence of undesirable outputs the issue of measuring technical efficiencies while considering undesirable outputs has been addressed by past studies but the proper method of including undesirable outputs has always been a subject of debate this article develops a data envelopment analysis dea based model that includes undesirable outputs the technologies of desirable output production and undesirable output control are considered simultaneously this allows one to transform undesirable output into desirable output whereby a traditional shephard distance function can be used to measure technical efficiencies an approach to measuring the impacts due to environmental regulations is then derived empirical results show that larger farms are more technically efficient than small sized farms but no clear conclusions can be reached for the measures of regulatory impact among farms with different sizes on average the sample farms incurred an opportunity cost due to environmental regulations equivalent to 9 8 of market value opportunity costs rise with efficiency

ecological total factor energy efficiency of regions in china most existing energy efficiency indices are computed without taking into account undesirable outputs such as co2 and so2 emissions this paper computes the ecological total factor energy efficiency etfee of 30 regions in china for the period 2005 2009 through the slack based model sbm with undesirable outputs we calculate the etfee index by comparing the target energy input obtained from sbm with undesirable outputs to the actual energy input findings show that china s regional etfee still remains a low level of around 0 600 and regional energy efficiency is overestimated by more than 0 100 when not looking at environmental impacts china s regional energy efficiency is extremely unbalanced the east area ranks first with the highest etfee of above 0 700 the northeast and central areas follow and the west area has the lowest etfee of less than 0 500 a monotone increasing relation exists between the area s etfee and china s per capita gdp the truncated regression model shows that the ratio of r d expenditure to gdp and the degree of foreign dependence have positive impacts whereas the ratio of the secondary industry to gdp and the ratio of government subsidies for industrial pollution treatment to gdp have negative effects on the etfee

non parametric productivity analysis with undesirable outputs an application to the canadian pulp and paper industry this article extends the chavas cox approach to non parametric analysis by incorporating undesirable outputs to provide a more complete representation of the production technology inner and outer non parametric technology bounds are constructed the methods are illustrated with application to time series data for the canadian pulp and paper industry conventional measures that ignore changes in pollutant outputs underestimate true productivity growth further there is a large gap between estimates generated with reference to inner and outer bounds to the technology suggesting that researchers need to be aware of the limitations of results derived from analyses relying only on dea methods copyright 2001 oxford university press

energy intensity and its determinants in china s regional economies abstract this paper contributes to the existing literature as well as policy debates by examining energy intensity and its determinants in china s regional economies the analysis is based on a comprehensive database of china s regional energy balance constructed for this project through its focus on regional china this study extends the existing literature which mainly covers nationwide studies it is found in this paper that energy intensity declined substantially in china the main contributing factor is the improvement in energy efficiency changes in the economic structure have so far affected energy intensity modestly thus there is considerable scope to reduce energy intensity through the structural transformation of the chinese economy in the future

the development and deployment of low carbon energy technologies the role of economic interests and cultural worldviews on public support large scale deployment of low carbon energy technologies is crucial to mitigating climate change and public support is an important barrier to policies and projects that facilitate deployment this paper provides insights to the origins of public opposition that can impede the adoption of low carbon technologies by investigating how perceptions are shaped by local economic interests and individual cultural worldviews the research considers both carbon capture and storage and wind energy technologies because they differ in maturity economic impact and resource base further for each technology the research examines support for two types of policies deployment in local community and public funding for research and development results indicate the influence of economic interests and cultural worldviews is policy specific individual cultural worldviews do not affect support for the deployment of technology but they do significantly influence a person s support for publicly funded research and development conversely local economic interests have a significant role in determining support for deployment while they do not affect support for research and development

is the implementation of energy saving and emission reduction policy really effective in chinese cities a policy evaluation perspective abstract reducing pollutant emissions while ensuring a stable economic growth is an important embodiment of sustainable development based on the national comprehensive demonstration of energy saving and emission reduction fiscal policy eser policy proposed by the chinese government in 2011 this paper analyzes the impact of such policy on emissions reduction and economic growth under the framework of differences in differences did method this paper first identifies the implementation conditions of eser policy then we adopt three specifications to control the endogenous problem for the selection of demonstration cities the robustness test verifies the reliability of our findings and the spillover effect analysis reveals the deficiency of this policy we reach the following conclusions 1 different from the previous studies we find that the eser policy can effectively reduce the pollutant emissions while ensuring a stable economic growth 2 however the event study reveals that the reduction effect is only existing in the demonstration period which means that this policy is not sustainable 3 furthermore we find no spillover effect of eser policy on the non policy targeted pollutant suggesting that the local government only cares about the reduction of policy targeted pollutants based on these findings we propose that the future energy saving and emissions reduction policy formulation should focus on the policy sustainability and overall environmental performance

undesirable outputs in efficiency valuations abstract efficiency measurement is usually based on the assumption that inputs have to be minimized and outputs have to be maximized in a growing number of applications however undesirable outputs are incorporated into the production model which have to be minimized in this paper various approaches for treating such outputs in the framework of data envelopment analysis dea are discussed and the resulting efficient frontiers are compared new radial measures are introduced which assume that any change of the output level will involve both undesirable and desirable outputs

modeling undesirable factors in efficiency evaluation abstract data envelopment analysis dea measures the relative efficiency of decision making units dmus with multiple performance factors which are grouped into outputs and inputs once the efficient frontier is determined inefficient dmus can improve their performance to reach the efficient frontier by either increasing their current output levels or decreasing their current input levels however both desirable good and undesirable bad factors may be present for example if inefficiency exists in production processes where final products are manufactured with a production of wastes and pollutants the outputs of wastes and pollutants are undesirable and should be reduced to improve the performance using the classification invariance property we show that the standard dea model can be used to improve the performance via increasing the desirable outputs and decreasing the undesirable outputs the method can also be applied to situations when some inputs need to be increased to improve the performance the linearity and convexity of dea are preserved through our proposal

the influence of market reform on the co2 emission efficiency of china abstract in recent years the constant advancement of market reform in china improves the market allocation efficiency of production factors and further promotes the rapid growth of economic aggregate output in the country additionally the co2 emitted in china also constantly increases based on panel data pertaining to 30 provinces from 1998 to 2015 in china the co2 emission efficiency and marketisation level of china were separately measured using a super slacks based measure approach and generalised principal component analysis on this basis by utilising a dynamic panel regression model and a panel smooth transition regression model the influence of market reform on co2 emission efficiency was explored the results show that the marketisation level exerts a significantly positive effect on co2 emission efficiency in both models and the results are robust on the condition of taking energy price as a threshold variable the influence of process of marketisation is significantly greater than that when taking technological progress as a threshold variable it implied that although energy price and technological progress both significantly promote the marginal effect of market reform on co2 emission efficiency the energy price shows a greater influence than technological progress infrastructure construction and urbanisation can inhibit the improvement of co2 emission efficiency additionally the proportion of secondary industries can delay the improvement of co2 emission efficiency

inequality of energy intensities across oecd countries a note abstract this paper proposes the use of theil s second measure to analyze international energy intensity differences this index allows differences to be broken down within and between groups of countries in a consistent manner an analysis of oecd countries for the period 1971 1999 shows some basic points first the fall in energy intensities differences is attributable both to within group and between group inequality components second between group inequalities are currently the main contributor to the whole inequality value finally a detailed exploration on within group inequalities reveals the significant explanatory role played by eu countries

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

weak and strong disposability vs natural and managerial disposability in dea environmental assessment comparison between japanese electric power industry and manufacturing industries the economic concept of weak and strong disposability has long dominated studies on dea data envelopment analysis environmental assessment this study reviews the two disposability concepts from their conceptual and methodological implications in particular this study is interested in the concept of weak disposability because the concept is believed to have an analytical capability to measure an occurrence of congestion the two economic concepts on disposability accepted by production economists are replaced by natural and managerial disposability in this study the natural disposability implies an environmental strategy by which a firm attempts to decrease an input vector to reduce a vector of undesirable outputs given the decreased input vector a firm attempts to increase a vector of desirable outputs as much as possible this type of strategy indicates negative adaptation in contrast the managerial disposability indicates an opposite strategy by increasing the input vector this disposability expresses an environmental strategy by which a firm considers a regulation change as a new business opportunity a firm attempts to improve its unified performance by utilizing new clean air technology and or new management the strategy indicates positive adaptation considering the two groups of disposability this study compares between weak strong disposability and natural managerial disposability in terms of their conceptual and methodological differences focusing upon the concept of congestion and technology innovation furthermore using the concept of natural and managerial disposability this study compares japanese electric power firms with manufacturing firms this study finds that the manufacturing firms outperform the electric power firms under natural disposability an opposite result is found under managerial disposability this empirical study also finds that the two groups of japanese firms have attained desirable good congestion due to technology innovation based upon such empirical results this study identifies two policy implications one of the two implications is that the two groups of japanese industries have attained a high level of technology innovation by a result of environmental regulation the other is that the electric power industry operates more efficiently to reduce the co2 emission than the manufacturing industries

changes to mutual fund risk intentional or mean reverting an empirical issue is whether a mutual fund s change in intertemporal risk is intentional or arises from risk mean reversion our methodology uses actual fund trades to identify funds that actively change risk funds that are statistically identified as trading to change return variance or tracking error variance do not exhibit risk mean reversion mostly funds trade to reduce risk and in particular tracking error variance this is most evident for funds that previously attained a low tracking error variance we find no evidence of a relation between past performance and intended changes to return variance or tracking error variance

total factor energy efficiency of regions in china abstract this paper analyzes energy efficiencies of 29 administrative regions in china for the period 1995 2002 with a newly introduced index most existing studies of regional productivity and efficiency neglect energy inputs we use the data envelopment analysis dea to find the target energy input of each region in china at each particular year the index of total factor energy efficiency tfee then divides the target energy input by the actual energy input in our dea model labor capital stock energy consumption and total sown area of farm crops used as a proxy of biomass energy are the four inputs and real gdp is the single output the conventional energy productivity ratio regarded as a partial factor energy efficiency index is computed for comparison in contrast to tfee our index is found fitting better to the real case according to the tfee index rankings the central area of china has the worst energy efficiency and its total adjustmentof energy consumption amount is over half of china s total regional tfee in china generally improved during the research period except for the western area a u shape relation between the area s tfee and per capita income in the areas of china is found confirming the scenario that energy efficiency eventually improves with economic growth

stock and option market divergence in the presence of noisy information we examine market behavior of the stock and option markets upon the arrival of noisy information in the form of cnbc s mad money recommendations if stock and option markets are not equally efficient they should respond differently to noisy information with the less efficient market more susceptible to noise we find that the stock market is less efficient than the option market the abnormal difference between option implied and actual stock returns is negative and significant upon exposure to noisy information this difference may yield an economically significant monthly trading profit of up to 5 we conclude that the stock market is more susceptible to noisy information than the option market and is therefore less efficient published by elsevier b v

nonparametric analysis of technical and allocative efficiencies in production in this paper we extend varian s 1984 nonparametric production analysis to situations when the set of observed output input and price data is not consistent with profit maximization for at least one firm in such cases varian s results imply that no production possibility set containing all observations can rationalize the observed data we identify each firm whose performance given the prices faced by it may be found consistent with profit maximization relative to some production possibility set containing all observed output input vectors we show that the set 4 of all such firms can itself be weaklv rationalized in the sense that there exists a closed convex and monotone production possibility set that contains all the observations and relative to which the performance of all the firms in the set 8o is consistent with profit maximization given their respective prices by definition firms not included in this largest set d of efficient observations unambiguously deviate from profit maximizing behavior for any production possibility set containing all observations we follow farrell 1957 and analyze these deviations into technical and allocative efficiency measures considering as admissible all closed convex and monotone production possibility sets relative to which the performance of each firm in the set g remains consistent with profit maximization we then describe nonparametric methods for determining the tightest upper and lower bounds on the technical allocative and aggregate efficiency measures evaluated relative to all such admissible production possibility sets it is seen that the tightest upper bound on the technical efficiency measure is the same as the value computed by the nonparametric efficiency evaluation technique known as data envelopment analysis thus establishing a link between this literature in management science operations research and the nonparametric production analysis in economics

efficiency evaluation of regional energy saving and emission reduction in china a modified slacks based measure approach abstract china s economic reform and opening policy has resulted in china s rapid growth especially in terms of economy unfortunately the growth has brought about huge consumption of energy and increasing emission of environmental pollution little research has been done which pays close attention to the efficiency evaluation of regional energy saving and emission reduction even though such evaluation is considered a crucial method in the fight to save resources and protect the environment aiming at evaluating the efficiency of regional energy saving and emission reduction of china we firstly construct an evaluation index system for input and output selection then a modified slacks based measure model is applied to measure the performance of energy saving and emission reduction an empirical study is done on 30 of mainland china s provincial level regions the results show that the energy saving and emission reduction efficiencies of the regions in china are generally at a low level more precisely china s regional regions performed really badly in energy saving although their emissions results are passable barely to resolve this problem several policy recommendations are proposed to improve the efficiency of regional energy saving and emission reduction of china

input price shocks and the slowdown in economic growth the case of u k manufacturing this paper provides a theoretical and empirical analysis of the effects of input price shocks on economic growth with a focus on united kingdom manufacturing in the 1970s the theoretical model predicts a discrete decline in output and productivity after an input price rise and a longer run slowdown in productivity growth real wage growth and capital accumulation these features characterize the united kingdom and most other oecd economies after 1973 the empirical results confirm the important role of input prices in recent u k adjustment but also point to an important role for other supply and demand factors two types of explanations have been offered for the sharp deterioration in u k economic performance in the past decade focusing respectively on demand and supply factors a standard keynesian view holds that macroeconomic demand management has been either too expansionary or too contractionary and that rising unemployment and falling output reflect the burden of anti inflationary policies an alternative view holds that various supply shocks are the main source of the poor output performance in this interpretation higher raw material prices particularly oil competition from the newly industrializing countries nics and perhaps an independent decline in productivity growth all have lowered output growth and raised unemployment

the transition of germany s energy production green economy low carbon economy socio environmental conflicts and equitable society low carbon transitions have been predominantly analysed using quantitative methods mostly building on present and forecasted data of social metabolism this paper addresses both the economic and social dimensions of low carbon emissions by analysing the presence of socio environmental conflicts in germany these conflicts appear to be a consequence of unsustainable policies targeting firms planning and behaviour mainly based on neoclassical economic thinking and various stakeholder groups that oppose carbon intensive businesses by applying a delphi method with 18 experts the authors analyse 117 socio environmental conflicts e g derived from extractive activity energy production and infrastructure projects in germany most of these conflicts include the struggle of various society groups to achieve a low carbon economy but also a more equitable society the analyses presented in this paper shows that germany provides both the best and the worse of achieving low carbon paths a significant investment into renewable energy but also a strong dependency on lignite which supplies the most polluting power stations of europe by addressing the problem from a historical perspective the authors demonstrate how carbon intensive extractive activity has been one of the major causes for environmental activism and protest in both socialist and capitalist societies

measuring the energy input substitution and output effects of energy price changes and the implications for the environment abstract previous studies of decomposition of factor inputs have limited their analysis on the estimation of substitution and output effects however this paper develops a two step approach to estimate the substitution and output effects of changes in energy demand resulting from changes in prices and further examines the implications of these effects on co2 emissions using european industrial dataset over the period 1995 2007 in our empirical estimations instead of relying only on isur model like previous studies we introduced a multilevel model which is a more befitting model to our data our analysis covers industry as a whole and for different sector types the primary results emerged from our analysis suggest a strong evidence using the multilevel model generally our results show that production inputs are substitutable we find the substitution and output effects to be negatively related to co2 emissions however the substitution effects dominate from policy perspectives our results suggest that output adjustments may not play a significant role in reducing emissions we find the overall effects of changes in energy demand to be moderate then we argue that increment in energy taxes should be complemented by cleaner factor substitution and sustainable growth to achieve a desirable carbon reduction

mutual fund trades and the value of contradictory private information abstract we investigate the performance of mutual funds that trade using private information these funds are uniquely identified from a set of 2730 funds with 44 315 fund periods between 1994 and 2005 we compare the alignment of fund trades with brokers recommendations which we regard as public information in the universe of informed and uninformed mutual funds funds that systematically trade counter to the public information form a homogenous subset of the privately informed funds by using private information that contradicts the public information these funds exhibit a superior average performance after we control for serial correlation in fund returns we assess this advantage as being an economically significant 1 7 per annum we also show empirically that smaller funds are better able to capture the benefit of private information

malmquist index measurement for sustainability enhancement in chinese municipalities and provinces abstract this study discusses a use of dea environmental assessment in a time horizon we use a radial approach to examine a dynamic change of index measures related to china s regional development and industrial pollution prevention in applying the proposed assessment to a time series data we need to examine components that produce a shift of an efficiency frontier in a time horizon a unique feature of the proposed assessment is that it incorporates a framework of malmquist index to examine the frontier shift among multiple periods here the frontier shift indicates a progress potential on technology development and or managerial improvement among observed periods thus it is not an efficiency measure rather the measurement eliminates inefficiency by shifting an organization to an efficiency frontier in this study the index is conceptually separated into 6 subcomponents which are further disaggregated into 12 different elements 6 subcomponents 2 disposability concepts under natural and managerial disposability concepts the proposed index measurement needs to consider a possible occurrence of a frontier crossover among different periods because technology diffusion on production activities usually has a time lag until it becomes really effective methodologically this study conveys the message that dea is an approximation method so being not perfect therefore it is necessary for us to use several different approaches e g potential improvement by measuring a frontier shift and efficiency analysis to obtain reliable empirical evidence as an application this study examines the level of sustainability related to 30 municipalities and provinces in china from 2003 to 2014 the following six policy implications are obtained in this study first all municipalities and provinces have made a considerable progress on their economies and pollution prevention efforts second the effect of the frontier crossover is limited in china because they attain a high level of their potentials on economic development and pollution prevention of course this effort is within the chinese boundary not international because this study does not compare them with other industrial nations third china needs to allocate its resources to western provinces at a level that it has used for coastal developments fourth the government should reinforce efforts on environmental protection in central and southern regions fifth the government has focused on the sustainability development in urban municipalities and provinces and then has gradually shifted the policy influence toward rural areas finally different empirical results are confirmed by the potential analysis which consists of the malmquist index measurement and the efficiency analysis both approaches need to be examined for future planning on chinese regional development

market reaction to business week inside wall street column a self fulfilling prophecy abstract this study focuses on stocks mentioned in a business week bw column in which over half the stories quote an analyst as a source the results of the study show that stocks with a favorable report in bw earn positive abnormal returns at the time of the distribution of the weekly however this is true only for stocks followed by less than twenty analysts within this group the market response increases as the number of analysts decreases stocks followed by more than twenty analysts do not respond at the time of their mention in bw we further document that trading volume increases at the time of the publication of the story the six month size adjusted post bw performance of the less closely followed stocks with favorable stories is negative and offsets the abnormal return at the time of the bw story we conclude that the evidence is consistent with the self fulfilling prophecy hypothesis i e traders react to bw stories and influence the prices of stocks only to lose in the long run six months the results also show that information obtained from non analyst sources has a greater impact on stock prices than the information from analyst sources indicating that some of analysts information is already reflected in prices through their clients trading the return reversion over six months is observed for bw stories with both analyst as well as non analyst sources

changes in carbon intensity in china empirical findings from 1980 2003 china experienced sustainable rapid economic growth over the period 1980 2003 but at the same time energy related carbon intensity showed a downward trend it begs the question therefore what factors were driving this decline in carbon intensity and will this decline be maintained in future moreover what measures can be adopted to ensure a continual decline in carbon intensity these questions led to increased research in the factors governing co2 emission in china this paper quantifies the driving force behind china s primary energy related carbon intensity and measures the material production sectors final energy related carbon intensity our results show that the overwhelming contributor to the decline of energy related carbon intensity was the reduction in real energy intensity however policies that focus only on the decline in energy intensity are insufficient to further decrease carbon intensity the change of primary energy mix can improve the decline of carbon intensity this should focus on the material production sectors development strategies and final energy use greater emphasis should be given to secondary industry which needs national and regional governments policy support

efficiency evaluation of chinese regional industrial systems with undesirable factors using a two stage slacks based measure approach abstract the process of a regional industrial system in china can be separated into two internal stages production stage and pollutant abatement stage this paper aims to examine the efficiency of chinese regional industrial systems by taking the operational performance of its two internal stages into consideration unlike traditional data envelopment analysis models that treat decision making units as black box when measuring their efficiencies with undesirable factors this paper proposes a two stage model based on slacks based measure to evaluate the efficiency of chinese regional industrial systems by decomposing the efficiency into production efficiency and abatement efficiency the proposed model can estimate the efficiencies of the whole regional industrial system its production stage and abatement stage simultaneously the model provides a way of improving performance of a regional industrial system through identifying its inefficient internal stages this can help to find out the main sources of the inefficiency that arise from the internal stages within the system which cannot be done by using conventional environmental data envelopment analysis models findings resulting from the model application show that there are great disparities in regional industrial systems efficiencies and the inefficiency of chinese industrial system is largely driven by the abatement stage

industrial energy efficiency with co2 emissions in china a nonparametric analysis abstract global awareness on energy security and climate change has created much interest in assessing economy wide energy efficiency performance a number of previous studies have contributed to evaluate energy efficiency performance using different analytical techniques among which data envelopment analysis dea has recently received increasing attention most of dea related energy efficiency studies do not consider undesirable outputs such as co 2 emissions in their modeling framework which may lead to biased energy efficiency values within a joint production framework of desirable and undesirable outputs in this paper we construct both static and dynamic energy efficiency performance indexes for measuring industrial energy efficiency performance by using several environmental dea models with co 2 emissions the dynamic energy efficiency performance indexes have further been decomposed into two contributing components we finally apply the indexes proposed to assess the industrial energy efficiency performance of different provinces in china over time our empirical study shows that the energy efficiency improvement in china s industrial sector was mainly driven by technological improvement

interprovincial two stage water resource utilization efficiency under environmental constraint and spatial spillover effects in china although existing studies have paid much attention to the measurement model of water resource utilization efficiency they have failed to consider the spatial spillover effect of some influencing factors of water resource utilization efficiency causing biased results this study measures the water resource utilization efficiency of 31 provincial administrative regions in china from 2001 to 2014 and the efficiency of each stage by adopting a slack based efficiency evaluation model based on the relaxation of two stages to consider undesirable output then this study employs a spatial durbin econometric model by considering spatial effect to analyze the influencing factors of the overall efficiency of water resource utilization by per capita water resources industrial water living water consumption per capita gross domestic product degree of opening to the outside world industrial structure technological progress and other aspects by comparison existing studies do not consider the spatial spillover effect this study estimates the direct and indirect effects of the influencing factors of water resource utilization efficiency to distinguish local and neighbors impacts of influencing factors of water resource utilization efficiency the results are as follows 1 first stage overall efficiency is significantly higher than second stage water resource utilization efficiency overall efficiency is close to second stage efficiency and second stage efficiency determines the overall effectiveness of water resource utilization 2 the spatial autocorrelation intensity of water resource utilization overall efficiency is significantly greater than zero and water resource utilization overall efficiency presents concentration distribution in the space for which the eastern coastal regions are high high type and the central and western regions are low low type 3 the overall efficiency of water resource utilization has spatial spillover effects and the region s overall efficiency is influenced by both region and neighborhood region 4 the direct and indirect effects of domestic water consumption degree of opening up and industrial structure are the primary significant influencing factors of overall efficiency of water resources in china the spatial spillover effects of domestic water consumption and industrial structure have a significant impact to improve water resource utilization efficiency the government and citizens should focus on such solutions as pollution reduction domestic water savings and transforming the industrial structure moreover china should consider the spatial effects of these influencing factors when government policies are designed

co2 emissions embodied in china us trade input output analysis based on the emergy dollar ratio to gain insight into changes in co2 emissions embodied in china us trade an input output analysis based on the emergy dollar ratio edr is used to estimate embodied co2 emissions a structural decomposition analysis sda is employed to analyze the driving factors for changes in co2 emissions embodied in china s exports to the us during 2002 2007 the results of the input output analysis show that net export of co2 emissions increased quickly from 2002 to 2005 but decreased from 2005 to 2007 these trends are due to a reduction in total co2 emission intensity a decrease in the exchange rate and small imports of embodied co2 emissions the results of the sda demonstrate that total export volume was the largest driving factor for the increase in embodied co2 emissions during 2002 2007 followed by intermediate input structure direct co2 emissions intensity had a negative effect on changes in embodied co2 emissions the results suggest that china should establish a framework for allocating emission responsibilities enhance energy efficiency and improve intermediate input structure

weak disposability in nonparametric production analysis with undesirable outputs environmental economics and natural resources group at wageningen university in the netherlands weak disposability of outputs means that firms can abate harmful emissions by decreasing the activity level modeling weak disposability in nonparametric production analysis has caused some confusion this article identifies a dilemma in these approaches conventional formulations implicitly and unintentionally assume all firms apply uniform abatement factors however it is usually cost effective to abate emissions in those firms where the marginal abatement costs are lowest this article presents a simple formulation of weak disposability that allows for non uniform abatement factors and preserves the linear structure of the model

energy capital substitution wage flexibility and aggregate output supply abstract this paper analyzes the relationship between factor substitution labor market conditions and aggregate output supply in order to study the transmission mechanism of energy price change to the rest of the economy it shows that the energy capital complementarity vs substitutability issue may turn out to be crucial in shaping the direction of the adjustment of aggregate output supply following energy price changes how crucial it is it is shown to depend on the beliefs of firms regarding the stock of capital on the degree to which labor markets clear and on the wage elasticity of labor supply some empirical evidence is presented about the relationship between energy price changes and output supply

a critical review of distance function based economic research on china s marginal abatement cost of carbon dioxide emissions abstract the last few years have witnessed a rapidly emerging literature estimating the marginal abatement cost or the shadow price of carbon dioxide co2 emissions in china using parametric or non parametric distance function approaches this is largely driven by the fact that china has become the world s largest carbon emitter and thus faced mounting domestic and international pressure to mitigate emissions there is an urgent policy need to model and predict the cost burdens of various mitigation scenarios consistent information about the marginal abatement cost of co2 emissions plays a crucial role in addressing this need however the existing literature has suffered from various issues that have severely weakened the scientific support that these studies could potentially provide for sound policy making this paper provides a thorough and critical review of this rapidly emerging literature and identifies important research directions that need the most attention from scholars

slacks based efficiency measures for modeling environmental performance we develop two slacks based efficiency measures for modeling environmental performance on the basis of environmental dea technology of the two measures one is a composite index with a higher discriminating power for modeling economic environmental performance and the other can be used to estimate the impacts of environmental regulations we apply the proposed measures to model the co2 emissions of 30 oecd countries from 1998 to 2002 and present the results obtained

social sustainability measured by intermediate approach for dea environmental assessment chinese regional planning for economic development and pollution prevention abstract this study examines the level of simultaneous achievement on economic prosperity and environmental protection so measuring the level of sustainability by a newly proposed intermediate approach conventionally dea data envelopment analysis for performance evaluation was used to assess various economic activities of organizations that utilized inputs e g the number of employees to yield desirable outputs e g the number of products the methodology was usually classified into radial or non radial category in an effort of extending it to environmental assessment dea needs to incorporate undesirable outputs e g the amount of co 2 into the computational framework this type of assessment is referred to as dea environmental assessment the proposed intermediate approach develops a new type of dea environmental assessment by combining the analytical features of radial approach with those of non radial approach the new approach measures the level of unified inefficiency on each production factor and determines the level of total unified inefficiency from the average of the sum of these inefficiency scores a rank sum test and a mean test are additionally incorporated into the proposed intermediate approach such a combination enhances the statistical capability as an application this study examines the level of sustainability related to 30 provinces in china from 2003 to 2014 the application finds four policy implications first it is important for china to allocate its resources to western provinces at a level that it has used for coastal developments second the government continues to reinforce the policy making effort on environmental protection by paying attention to central and southern regions the chinese industries need to transfer toward green energy the transfer should be efficiently executed for their future developments third the government has focused on the sustainability development in urban provinces and then has gradually shifted the policy influence toward rural areas finally the policy implementation needs a time lag until it becomes effective the time lag on economic policy is longer than that of environmental policy the economic policy has historically produced a regional imbalance often leading to educational and income imbalances among chinese provinces

co2 emissions and logistics performance a composite index proposal abstract the importance of good logistics performance for low no fossil carbon economies is widely recognized especially because the transport sector is responsible for a substantial portion of the world s greenhouse gas emissions this research evaluates efficiency in the relationship between transport logistics performance as measured by the logistics performance index lpi and co2 emissions from the transport sector the slacks based measure sbm of the data envelopment analysis dea was used to construct a low carbon logistics performance index lclpi ranking a group of 104 countries that were selected using the available data the empirical model adopted one input co2 emissions for the transport sector and seven outputs gross domestic product gdp and the six components of the lpi gdp has been included as a non discretionary output because co2 emissions are directly dependent on a country s economic production while the lpi is a qualifier to evaluate how the composite index evolved over time we used an approach that combines the techniques of window analysis and the malmquist index considering the dea results the countries that performed best in terms of the lclpi were japan germany togo benin and the united states and the more evolved countries were luxemburg ireland lebanon and honduras for the purposes of lclpi validation and analysis the performances of the brics brazil russia india china and south africa countries were analyzed especially china which is the world s second largest co2 emitter the proposed composite index and the ranking of countries in terms of logistics performance and co2 emissions can help identify the best performing countries in low carbon logistics
