demand for money in open economies abstract the demand for real cash balances deduced from an underlying portfolio model of the financial market is shown to depend upon domestic variables and foreign monetary developments the model is estimated using quarterly postwar data for canada germany uk and us there is clear evidence that demand for money is affected not only by changes in domestic variables such as permanent income domestic interest rate and price expectations but also by fluctuations in exchange rate expectations and foreign interest rates the conclusion that domestic monetary policy is fairly ineffective and domestic financial markets are highly vulnerable to changes in foreign financial and monetary developments need to be modified in light of the results presented in this paper

a cross country analysis of aggregate energy and carbon intensities abstract an update on the study by ang energy economics 9 1987 274 286 shows substantial changes in the relationship between energy consumption and national output across world countries from 1975 to 1997 while the ratio of commercial energy consumption to national output increases across countries as per capita income increases in 1975 the converse is observed in 1997 the cross country energy elasticity has also dropped from values well above unity to below or close to unity using the 1997 data the relationship between co 2 emissions and national output across countries is studied and the results show some interesting differences from that between energy consumption and national output

efficiency analysis of hydroelectric generating plants a case study for portugal abstract this paper estimates changes in total productivity breaking this down into technically efficient change and technological change by means of data envelopment analysis dea applied to the hydroelectric energy generating plants of edp the portugal electricity company the aim of this procedure is to seek out those best practices that will lead to improved performance in the energy market we rank the plants according to their change in total productivity for the period 2001 2004 concluding that some plants experienced productivity growth while others experienced a decrease in productivity the implications arising from the study are that edp should adopt an internal benchmark management procedure in order to evaluate the relative position of each hydroelectric generating plant and to adopt managerial strategies designed to catch up with the frontier of best practices as the frontier is shifting along the time constant efforts are needed in this respect along the time

carbon emission performance evaluation and allocation in chinese cities abstract this paper presents a dea approach with multiple abatement factors to evaluate co2 emission performance and allocate co2 emission quotas in chinese cities we first consider the difference of marginal abatement costs among cities and construct the non radial directional distance function with multiple abatement factors the total factor co2 emission performance index and its dynamic change index are then proposed to measure co2 emission performance considering equity and efficiency we develop a composite index by the hybrid method to allocate emissions quota which considers co2 emissions as well as co2 emission performance then we conduct an empirical study using inputs and outputs dataset of 71 chinese cities in 2005 2012 chinese cities have poor energy efficiency and still have high co2 emissions the eastern region outperforms the central region and the western region performs worst whereas the dynamic co2 emission performance of the central region has the largest increase the change of co2 emission performance is driven mainly by technological advances as for the co2 emission allocation the composite index method encourages cities to reduce emissions and enhance emission performance through carbon trading market it also motivates cities with high historical emissions to reduce their emissions by improving technology when they have poor co2 emission performance

carbon dioxide emissions allocation a review carbon dioxide co2 emissions allocation plays a fundamental role in determining reduction responsibility at economy level or emission permits at firm level past decades have seen the development and applications of various methods for co2 emissions allocation this paper provides a literature review of co2 emissions allocation with emphasis on the evolution of allocation methods used it begins with a summary of the most popular allocation principles and criteria that lay a foundation for the development of allocation methods we then classify the existing allocation methods into four groups namely indicator optimization game theoretic and hybrid approaches the main features and findings of past studies are identified and summarized while the fairness principle prevails in earlier studies the efficiency principle has been found to receive increasing attention recently we also present a comparison of the empirical results based on ten popular indicator methods to show how indicator choice affects the allocation results issues related to selecting appropriate methods in co2 emissions allocation are finally discussed further research may be carried out to strike a balance between fairness and efficiency so that the allocation results become more widely acceptable and economically feasible

on the design of optimal grandfathering schemes for emission allowances to meet its commitment under the kyoto protocol the eu plans to implement an emissions trading system whith grandfathering of allowances besides having distributional impacts the choice of the grandfathering scheme may affect efficiency if firms anticipate how future allocations depend on upcoming decisions in this paper we determine central design rules for optimal grandfathering within a simple two period model we find that for small open trading systems where allowance prices are exogenous first best second period grandfathering schemes must not depend on firm specific decisions in the first period second best schemes correspond to a ramsey rule of optimal tax differentiation and are generally based on both previous emissions and output however ofr closed emissions trading systems i e endogeneous allowance prices firstand second best rules coincide and must not depend on previous output levels they consist of an assignment proportional to the emissions in the first period plus a term which does not depend on firm specific decisions in either of the two periods

the political economy of global carbon emissions reductions abstract the discussion about what reductions in greenhouse gas emissions are required and how the emissions rights might be distributed globally has fostered the belief that there is a fundamental conflict between the rich nations of the north and the poor but populous nations of the south the argument is that grandfathering the rights will only reinforce existing global inequalities while per capita distribution of the rights would lead to such huge transfers of wealth to the south as to be unacceptable to the north however a very simple general equilibrium model highlighting key elements of the global economy shows that this perception is incorrect under a plausible interpretation of the goal of the united nations framework convention on climate change to avoid dangerous anthropogenic interference with the climate system instead of using an economic damage function to determine the optimal level of emissions reductions the model s utility functions are calibrated to reflect scientific understanding of what would be required to stabilize the atmosphere at safe concentrations of greenhouse gases among policy options that would accomplish this the united states has a preference for grandfathering the allocation of emissions rights over a per capita allocation but this preference is not strong and could be offset by other geopolitical considerations

efficient allocation of co2 emissions in china a zero sum gains data envelopment model abstract the appropriate allocation of co 2 emission quotas can build up a solid foundation for future emissions trading building co 2 emissions allocation mechanism has significant practical implications based on radial zero sum gains data envelopment zsg dea allocation model this paper uses a non radial zsg dea model to allocate co 2 emissions between different chinese provinces unlike previous studies treating co 2 as the input variable we treat co 2 as the undesirable output variable the modified model can better reflect macro production process while earlier relevant models treated co 2 emissions as inputs this paper contributes to the existing resource allocation method and allocates china s provincial co 2 emissions from the view of technical efficiency the results of our paper reveal that 1 between 2006 and 2010 the cumulative optimal amounts of co 2 emissions were higher than the actual amounts in 12 provinces and lower in other 18 provinces 2 several energy abundant provinces such as shanxi and inter mongolia need to take more responsibilities in co 2 emissions reduction 3 after the zsg dea allocation all provinces co 2 emissions are on zsg dea frontier which reflects the overall pareto optimality

sources of production inefficiency and productivity growth in china a global data envelopment analysis abstract the current mode of production in china is extensive and inefficient and has caused great stress on both resources and the environment this paper focuses on analyzing the sources of production inefficiency and productivity growth in china here a developed slacks based measure is utilized to decompose production inefficiency into three components input inefficiency economic output inefficiency and environmental inefficiency furthermore by applying a method based on global data envelopment analysis we take a further step to analyze the key factors responsible for the change of environmental productivity during 2003 2011 from the point of view of technical progress productive scale and management level the results show that redundancy in energy and labor inputs and excessive emission of sulfur dioxide chemical oxygen demand and ammonia nitrogen are the main sources of production inefficiency in china during the sample period the efficiency in all inputs and environmental emissions has improved except for capital input efficiency which had a decreasing trend further analysis shows that the overall environmental productivity in china has begun to follow an ascending path technical progress is the most powerful contributor to china s productivity growth while the decreases in scale and management efficiency are the two main obstacles preventing productivity improvement

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

econometric estimation of technical and environmental efficiency an application to dutch dairy farms in this article we estimate the technical and environmental efficiency of a panel of dutch dairy farms nitrogen surplus arising from the application of excessive amounts of manure and chemical fertilizer is treated as an environmentally detrimental input a stochastic translog production frontier is specified to estimate the output oriented technical efficiency environmental efficiency is estimated as the input oriented technical efficiency of a single input the nitrogen surplus of each farm the mean output oriented technical efficiency is rather high 0 894 but the mean input oriented environmental efficiency is only 0 441 intensive dairy farms are both technically and environmentally more efficient than extensive farms

consistent multi level energy efficiency indicators and their policy implications in order to cope with the global warming issue most of the asia pacific economic cooperation apec economies have made energy conservation policy a top priority in terms of their energy policies the energy efficiency indicators included in the present paper focus on the micro foundation aspects there are basically two types of energy efficiency indicators namely the economic thermodynamic energy efficiency indicators that use real gdp as the denominator and the physical thermodynamic energy efficiency indicators that are based on the output volume index while the common definitions and consistent methodology used in the present paper fulfill the iea pyramid eei concept the new methodology in this paper compares the decomposition effects between upstream and downstream industries when aggregating efficiency changes these decomposition effects can thereby provide valuable explanations for the energy conservation policy needed by energy policy and government administrators

allocation of co2 emission permits economic incentives for emission reductions in developing countries the economic impacts on developing regions following a global cap and trade system for carbon dioxide are assessed through the use of an energy economy systems model both an equal per capita allocation and a contraction and convergence allocation with convergence of the per capita emissions by 2050 are shown to offer economic incentive for africa india and probably also latin america to accept binding emissions commitments under a 450 ppm carbon dioxide stabilization scenario the gain for latin america is mainly a result of increased export revenues from sales of bio fuels as a result of the climate policy it is on the other hand unlikely that these allocation approaches would offer an economic incentive for china to join the regime because of its high economic growth present higher per capita emissions than india and africa and more costly mitigation options than latin america a more stringent allocation for developing countries such as contraction with convergence of the per capita emissions by the end of this century is estimated to generate reduced net gains or increased net losses for the developing regions though africa is still expected to gain

the co2 emission gini index and the environmental efficiency an analysis for 60 leading world economies abstract the aim of this study was to analyze the co 2 emission gini index and the environmental efficiency for 60 leading world economies in 2010 we consider the technological heterogeneity dividing the sample into similar groups and estimating environmental efficiency indicators into metafrontier and group frontiers despite the fact that pollution concentration is more prominent in developed countries the results showed that this group is more efficient on the other hand lower income group and medium technology countries present the worst indicators we could conclude that the inefficiency observed in developed countries group was attributed to mismanagement while in the developing countries group the inefficiency could be related to technological differences

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

estimating the environmental efficiency and marginal co2 abatement cost of coal fired power plants in china abstract we estimate the environmental efficiency reduction potential and marginal abatement cost of carbon dioxide co2 emissions from coal fired power plants in china using a novel plant level dataset derived from the first and second waves of the national economic survey which were implemented in 2004 and 2008 respectively the results indicate that there are large opportunities for co2 emissions reduction in china s coal fired power plants given that all power plants operate fully efficiently china s co2 emissions in 2004 and 2008 could have been reduced by 52 and 70 respectively accompanied by an expansion in electricity output in other words the opportunities for double dividend exist in 2004 the average marginal abatement cost of co2 emissions for china s power plants was approximately 955 yuan ton whereas in 2008 the cost increased to 1142 yuan ton the empirical analyses show that subsidies from the government can reduce environmental inefficiency but the subsidies significantly increase the shadow price of the power plants older and larger power plants have a lower environmental efficiency and marginal co2 abatement cost the ratio of coal consumption negatively affects the environmental efficiencies of power plants

reducing conflict in global warming policy the potential of equity as a unifying principle abstract international agreement on global warming mitigation is likely to prove difficult efficiency based policies will result in disparate costs and benefits among nations and thus hinder cooperation this paper suggests that consideration be given to an equitable sharing of the economic impacts of global warming policy acknowledging that there is no universally held concept of equity the policy implications of several alternatives are explored because there is considerable variation in these implications it will be important for decision makers to clarify their preferred concepts of equity during the course of their negotiations on policies to address global warming

the decrease of co2 emission intensity is decarbonization at national and global levels abstract this viewpoint proposes the definition decarbonization refers to a decrease of co2 emission intensity in a trend this viewpoint then argues that an analysis of decarbonization at national and global levels based on that definition would lead to the correct calculation of decarbonization

dea approach for unified efficiency measurement assessment of japanese fossil fuel power generation this study discusses a new dea data envelopment analysis approach to measure the unified operational and environmental efficiency of energy firms it is widely known that they produce not only desirable good outputs e g electricity but also undesirable bad outputs e g co2 as a result of their plant operations the proposed approach incorporates an output separation desirable and undesirable outputs for the performance evaluation of energy firms in addition to the output separation this study separates inputs into energy and non energy inputs consequently the proposed approach incorporates not only the output separation but also the input separation within a computational framework of dea non radial measurement this study compares the proposed approach with other previous dea approaches used for the performance evaluation of energy firms after the methodological comparison this study applies the proposed approach for measuring the unified efficiency of japanese fossil fuel power generation this empirical study confirms that the implementation of kyoto protocol 2005 has not been effective on the unified efficiency of japanese fossil fuel power generation during the observed period 2004 2008 although the empirical result is inconsistent with the current japanese environmental policy under kyoto protocol it contains policy implications for guiding the future direction of japanese environmental policy on the electric power industry

does factor market distortion inhibit the green total factor productivity in china abstract this article measures green total factor productivity gtfp to discuss whether factor market distortions inhibit the green development of china s economy meanwhile export and foreign direct investment fdi are taken into account based on a threshold model considering export and fdi are closely related to factor market distortion environment and the economy the result shows that the factor market distortion has negative influences on china s gtfp growth export and fdi s spillover effect significantly moreover factor market distortion was found to be the threshold of export and fdi s spillover effect leading to inferior export and fdi which further inhibit gtfp growth this article provides a supplement to the issue from the perspective of environment based on the widely confirmed proposition that factor market distortion inhibits tfp growth according to the results we suggest that the chinese government should reduce the control of factor market as much as possible leaving the factor resources allocation to the market this will not only promote an innovation driven development but also an energy saving and environment friendly economy in china the article provides a new perspective on the influence mechanism of export and fdi on gtfp growth by discussing the impact path of factor distortion and expands the empirical framework of the research direction as well

the demand for money in an open economy the united kingdom most previous studies have estimated the demand for money without paying too much attention to developments in the foreign exchange markets in light of the fact that any development abroad and in the foreign exchange markets could have implications for domestic stabilization we make an attempt to incorporate such developments into the demand for money in the united kingdom more precisely after incorporating a measure of real effective exchange rate of the british pound into a dynamic money demand function we estimated it for the uk using quarterly data over 1973 87 period by relying upon the akaike final prediction error criteria to select the optimum number of lags it is shown that in addition to income and interest rate the real effective exchange rate exerts significant effect on the uk demand for money in the short run as well as long run

the low carbon technology characteristics of china s ferrous metal industry abstract the ferrous metal industry is the largest energy consuming industrial sector in china this paper examines the low carbon production characteristics of this industry during the period 1980 2013 we employ the duality theory of the weighted russell directional distance function to propose a general procedure for modeling production characteristics with carbon emissions being considered the undesirable output using the weighted russell directional distance function model we measure the carbon adjusted technical efficiency and environmental regulatory costs for this industry to investigate policy effects we test the porter hypothesis using the granger causality between regulatory cost and technical efficiency by using the dual model of weighted russell directional distance function we estimate the carbon shadow pricing and inter factor substitution possibilities results show that the carbon adjusted technical efficiency and environmental regulation costs of the chinese ferrous metal industry have significantly increased in recent decades however the latter does not significantly cause the improvement of former the indirect morishima elasticities of substitution reflect that the increase of fixed assets will effectively improve the carbon emissions performance of the chinese ferrous metal industry finally some policy implications are suggested

auction approaches of long term contracts to ensure generation investment in electricity markets lessons from the brazilian and chilean experiences the implementation of auctions of long term electricity contracts is arising as an alternative to ensure generation investment and therefore achieve a reliable electricity supply the aim is to reconcile generation adequacy with efficient energy purchase correct risk allocation among investors and consumers and the politico economic environment of the country in this paper a generic proposal for a long term electricity contracts approach is made including practical design concepts for implementation this proposal is empirically derived from the auctions implemented in brazil and chile during the last 6 years the study is focused on practices and lessons which are especially useful for regulators and policy makers that want to facilitate the financing of new desirable power plants in risky environments and also efficiently allocate supply contracts among investors at competitive prices although this mechanism is generally seen as a significant improvement in market regulation there are questions and concerns on auction performance that require careful design and which are identified in this paper in addition the experiences and proposal described can serve to derive further mechanisms in order to promote the entrance of particular generation technologies e g renewables in the developed world and therefore achieve a clean electricity supply

fiscal spending and green economic growth evidence from china abstract the green economy is considered as an efficient way for sustainability but the connection between fiscal spending and green economic growth has not been systematically explained this paper attempts to fill this research gap based on the panel data of 282 prefecture level cities from 2005 to 2016 we first construct the green economic growth index by using the non radial direction distance function then by employing the system gmm estimation we further evaluate the effect of fiscal education spending and r d spending on green economic growth finally we explore the potential mechanism and discuss our findings we obtain the following conclusions 1 the green economic growth index fluctuated in the study period we attribute it to the political tournament of local governments 2 the system gmm estimation results confirm the existence of composition effect and technique effect in the full sample but the sub sample analysis suggests that there is a heterogeneous effect in different areas with different resources abundant degree 3 mechanism analysis illustrates that fiscal r d spending and education spending foster the green economic growth through technological activities and human capital intensive activities respectively but they exhibit distinct roles in different areas based on these findings we propose some targeted policy suggestions for promoting green economic growth

regional allocation of carbon emission quotas in china evidence from the shapley value method abstract it is an important task for china to allocate carbon emission quotas among regions so as to realize its carbon reduction targets and establish the national cap and trade carbon market meanwhile it is supposed to be cost effective to jointly reduce china s carbon emissions through some collaborative activities among regions then a natural question is how to allocate the quotas among regions in light of the collaboration for this purpose the shapley value method is adopted and the results show that first the regions with higher gdp higher carbon outflow and higher carbon reduction connection should be allocated more carbon quotas moreover when the collaboration is considered the optimal allocation of carbon quotas among regions will change significantly compared to the basic quotas by the entropy method and the central region is allocated the largest proportion of carbon quota among regions which indicates its largest radiation effect besides the collaboration between the central region and northern coast region and that between the central region and the eastern region should be paid close attention these results may provide insightful support for decision makers to promote collaborative carbon reduction and allocate carbon quotas in china

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

the optimal initial allocation of pollution permits a relative performance approach the initial allocation of pollution permits is an important aspect of emissions trading schemes we generalize the analysis of bohringer and lange 2005 eur econ rev 49 8 2041 2055 to initial allocation mechanisms that are based on inter firm relative performance comparisons including grandfathering and auctions as well as novel mechanisms we show that using firms historical output for allocating permits is never optimal in a dynamic permit market setting while using firms historical emissions is optimal only in closed trading systems and only for a narrow class of allocation mechanisms instead it is possible to achieve social optimality by allocating permits based only on an external factor which is independent of output and emissions we then outline sufficient conditions for a socially optimal relative performance mechanism

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

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

technical efficiency shadow price of carbon dioxide emissions and substitutability for energy in the chinese manufacturing industries abstract china is the world s largest co 2 producer and energy consumer in this paper we calculate the maximum technically obtainable co 2 emissions reduction from the efficient use of inputs and estimate the shadow prices of co 2 emissions in order to assess the potential cost savings deriving from trading emissions among industries by measuring the input distance function for 30 chinese manufacturing industries our empirical results indicate that co 2 emissions could be reduced by as much as 680 million tons in the aggregate the shadow prices of co 2 vary from a high of 18 82 to a low of zero across industries with an average of 3 13 per ton additionally the estimated indirect morishima elasticities of substitution of capital for fossil fuels indicate that the substitutabilities of capital for oil gas and coal are higher than the substitutability for labor

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

effort sharing in ambitious global climate change mitigation scenarios abstract the post 2012 climate policy framework needs a global commitment to deep greenhouse gas emission cuts this paper analyzes reaching ambitious emission targets up to 2050 either 10 or 50 from 1990 levels and how the economic burden from mitigation efforts could be equitably shared between countries the scenarios indicate a large low cost mitigation potential in electricity and industry while reaching low emission levels in international transportation and agricultural emissions might prove difficult the two effort sharing approaches triptych and multistage were compared in terms of equitability and coherence both approaches produced an equitable cost distribution between countries with least developed countries having negative or low costs and more developed countries having higher costs there is however no definitive solution on how the costs should be balanced equitably between countries triptych seems to be yet more coherent than other approaches as it can better accommodate national circumstances last challenges and possible hindrances to effective mitigation and equitable effort sharing are presented the findings underline the significance of assumptions behind effort sharing on mitigation potentials and current emissions the challenge of sharing the effort with uncertain future allowance prices and how inefficient markets might undermine the efficiency of a cap and trade system

the decomposition of total factor co2 emission efficiency of 97 contracting countries in paris agreement abstract greenhouse gas reduction requires joint efforts from the global society while improving co2 emission efficiency is a centrally important means to realize emission reduction targets therefore it is of strategic importance to identify main influential factors to co2 emission efficiency of different countries by considering the technology heterogeneity the originality herein lies in that applying the modified decomposition method of metafrontier malmquist luenberger index mml to define the priority of contracting countries in paris agreement to improve emission efficiency in this study 97 contracting countries of paris agreement are divided into 4 groups according to levels of income low income countries lower middle income countries upper middle income countries and high income countries and studied with their input and output data during 1990 2014 as samples the empirical results reveal that the paths for the contracting countries of paris agreement to improve the efficiency are different first lower middle income group can be facilitated through increasing factor input to increase the mml index considering the highest increase in scale efficiency 2 78 second low income group should eliminate the excessive concentration of inputs by enhancing the energy management efficiency third in terms of the significant advancement of high income group s mml index brought by technology advancement and the abnormal drop of brunei darussalam s mml related to technology decay this analysis emphasized that the advancement and innovation of energy technology are the main force for total factor co2 emission efficiency improvement

how can china reach its co2 intensity reduction targets by 2020 a regional allocation based on equity and development in late 2009 the chinese government committed to cut its carbon dioxide emissions per unit of gross domestic product gdp by 40 to 45 of 2005 levels by 2020 this has raised the issue of how to allocate the co2 reduction target regionally to meet the national reduction target to meet this objective the following aspects may be taken into consideration equity principles common but differentiated responsibilities intensity reduction target fulfillment and economic difference and reduction potential among provinces this paper selects per capita gdp accumulated fossil fuel related co2 emissions and energy consumption per unit of industrial added value as indicators for emission reduction capacity responsibility and potential respectively based on these three indicators a comprehensive index is developed and an intensity allocation model constructed as decision makers may have different preferences when allocating the reduction burden we allocate different weights to the indicators analyzing the results using cluster analysis the following aspects may also be considered together with the national regional development strategy to determine how to share the burden the reduction potential of various regions implementation potential of the plans and promotion of a highly efficient low carbon economic development model

a deterministic parametric metafrontier luenberger indicator for measuring environmentally sensitive productivity growth a korean fossil fuel power case abstract this paper contributes to the current literature by proposing an alternative parametric metafrontier productivity approach called the deterministic parametric metafrontier luenberger productivity indicator dpmlpi for measuring environmentally sensitive productivity growth incorporating technological heterogeneities the luenberger productivity indicator is constructed based on a quadratic output directional distance function with undesirable outputs and then combined with the deterministic metafrontier to develop dpmlpi the dpmlpi can be decomposed into efficiency change technological change and productivity growth gap the productivity growth gap can be further divided into efficiency change gap and technological change gap the parametric linear programming technique is used to estimate parameters and construct the metafrontier an empirical study for the korean fossil fuel power industry at the plant level is conducted for the 2003 2011 period the results show a 0 15 increase in environmentally sensitive productivity growth which is mainly driven by environmental technological change the oil fired power plants show higher levels than the coal fired ones of environmentally sensitive productivity growth and technological change performance some related policy implications are also proposed for the korean fossil fuel power sector

efficiency productivity and environmental policy a case study of power generation in the eu this study uses the eu public power generating sector as a case study to investigate the environmental efficiency and productivity enhancing performance of the european union s co2 emissions trading scheme eu ets in its first phase using data envelopment analysis methods we measure the environmental efficiency and the productivity growth registered in public power generation across the eu over the 1996 2007 period in the second stage of our analysis we attempt to explain changes in productivity and efficiency over time using econometric techniques our analysis suggests two conclusions carbon pricing led to an increase in environmental efficiency and to a shift outwards of the technological frontier and the overly generous allocation of emission permits had a negative impact on both measures these results are shown to be robust to changes in controls and specifications

cointegration real exchange rate and modelling the demand for broad money in japan the literature on the demand for the japan s broad money addresses two controversial issues the form log level or log difference in which variables enter the money demand function and the question of whether financial innovation and deregulation caused shift s in the money demand relationship log level specifications of the money demand function have been shown to exhibit large shifts whereas log first differences and error correction specifications do not our paper demonstrates that the appropriate specification for the japanese money demand function is that which uses cointegration and error correction procedures

the integrated efficiency of economic development and co2 emissions among asia pacific economic cooperation members abstract in recent years the evaluation of energy economic and environmental efficiency employing the data envelopment analysis models has been a hot topic in academe when choosing models people always expect to improve desirable outputs while reducing undesirable outputs at the same time e g when using a directional distance function model however directional distance function models may lead to biased estimations due to different directions given to different units to overcome this shortcoming in this paper we propose another non radial efficiency evaluation model based on previous literature which can also improve desirable outputs and reduce undesirable outputs then we employ this model to analyse the economic efficiency and co 2 emissions efficiency of the asia pacific economic cooperation apec members meanwhile we also measure the efficiency change by using the luenberger index and analyse the reasons for efficiency changes from the perspectives of technical efficiency and technical changes the results indicate that most countries have an extremely high economic efficiency but relatively low co 2 emissions efficiency and integrated efficiency except for the united states japan and singapore according to the luenberger index we find an increase in integrated efficiency and co 2 emissions efficiency for most members from 2001 to 2010 however technical progress is the main contributor technical efficiency exhibits a downward trend for most members

driving forces of residential co2 emissions in urban and rural china an index decomposition analysis abstract there exist many differences between urban and rural china among which residential co 2 emissions arising from energy consumption is a major one in this paper we estimate and compare the energy related co 2 emissions from urban and rural residential energy consumption from 1991 to 2004 the logarithmic mean divisia index decomposition analysis is then applied to investigate the factors that may affect the changes of the co 2 emissions it is found that energy intensity and the income effects respectively contributed most to the decline and the increase of residential co 2 emissions for both urban and rural china in urban china the population effect was found to contribute to the increase of residential co 2 emissions with a rising tendency however in rural china the population effect for residential co 2 emissions kept decreasing since 1998

green productivity growth in china s industrial economy abstract this paper uses a directional distance function ddf and the malmquist luenberger productivity index to estimate the changing patterns of green total factor productivity gtfp growth of 38 chinese industrial sectors during the period 1980 2010 unlike the measures of traditional total factor productivity tfp growth the ddf incorporates carbon dioxide emissions as an undesirable output directly into the production technology which credit sectors for simultaneously reducing their emissions and increasing their output our estimates of aggregate and sector level gtfp growth reveal that chinese industry is not yet on the path towards sustainable low carbon growth a dynamic panel data analysis of the determinants of gtfp across sectors is used to identify factors that might rectify this situation including state owned enterprise soe reform the growth of small private enterprises continued openness to foreign investment and higher spending on r d particularly in emission intensive sectors

analysis of the effect and potential of energy conservation in china in this paper a quantitative algorithm for direct and indirect energy savings is developed based on the database analysis of china s energy consumption per gdp in the last two decades the result shows that direct energy savings due to improved energy conversion and end use utilization efficiencies only account for 26 5 of the total energy savings and that indirect energy savings due to increased added value of products product shifts and structure shifts in industries account for 73 5 of the total energy savings factors affecting indirect energy savings are then analyzed and total energy system efficiencies and direct energy savings in 2020 are quantitatively estimated which shows that enlarging indirect energy savings is a more crucial task for china s macro energy conservation in the future the paper suggests that china should pay more attention to indirect energy savings to improve the energy utilization output benefits by increasing the added value of products optimizing product and industry structures and improving production technologies the potential of indirect energy savings in china is more significant compared with developed countries

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

evaluating the interplays among economic growth and energy consumption and co2 emission of china during 1990 2007 the interplays among economy and energy and environment have been widely concerned this paper put forward several indicators to quantify the relationships among economic growth and energy consumption and co2 emission as an example these indicators were applied to evaluate the comprehensive performances of china during 1990 2007 the results show that chinese people has been living a better life with chinese rapid economic growth but not synchronously in urban and rural areas non carbon energy resources share has increased however fossil energy resources have still acted as the main driver for chinese economic growth during this period technical progress has improved the fossil energy efficiency of chinese economic activity which leads to co2 emission per unit gdp and co2 emission per capita unit gdp dropping simultaneously however the two indicators annual decline rates become smaller and smaller which reflects that technical progress role is dropping and economic scale s effect is climbing people s survival has a rising contribution to co2 emission co2 emission per capita has increased which shows that economic scale has greater impact on co2 emission than technical progress does relatively speaking chinese development patterns have become more and more sustainable during this period finally based on the related issues being discussed some corresponding suggestions are put forward for chinese government to further coordinate the relationship among economic development and energy consumption and co2 emission the proposed indicators can form a set of useful tool for policy makers to promote the harmonious development of economy and energy and environment in different regions and countries

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

metafroniter energy efficiency with co2 emissions and its convergence analysis for china this paper measures the energy efficiency performance with carbon dioxide co2 emissions in 30 provinces in china during the period of 1997 2011 using a meta frontier framework with the improved directional distance function ddf we construct a new environmental production possibility set by combining the super efficiency and sequential data envelopment analysis dea models to avoid discriminating power problem and technical regress when evaluating efficiency by ddf then it is used in a meta frontier framework to reflect the technology heterogeneities across east central and west china the results indicate that eastern china achieved the highest progress inefficiency relative to the metafrontier followed by western and the central china by focusing on technology gaps we offer some suggestions for the different groups based on group frontier and meta frontier analyses the inefficiency can be attributed to managerial failure for eastern and western china and technological differences for central china the convergence analysis shows that energy and co2 emission governance will produce negative effects on economic growth and it is suitable and acceptable to introduce rigorous environmental measures in eastern china

cost efficiency and optimal scale of electricity distribution firms in taiwan an application of metafrontier analysis abstract this paper analyzes the cost efficiency and optimal scale of taiwan s electricity distribution industry due to the substantial difference in network density firms may differ widely in production technology we employ the stochastic metafrontier approach to estimate the cost efficiency of 24 distribution units during the period 1997 2002 empirical results find that the average cost efficiency is overestimated using the traditional stochastic frontier model especially for low density regions the average cost efficiency of the high density group is significantly higher than that of the low density group as it benefits from network economies this study also calculates both short term and long term optimal scales of electricity distribution firms lending policy implications for the deregulation of the electricity distribution industry

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

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

examining the cost efficiency of chinese hydroelectric companies using a finite mixture model this paper evaluates the operational activities of chinese hydroelectric power companies over the period 2000 2010 using a finite mixture model that controls for unobserved heterogeneity in so doing a stochastic frontier latent class model which allows for the existence of different technologies is adopted to estimate cost frontiers this procedure not only enables us to identify different groups among the hydro power companies analysed but also permits the analysis of their cost efficiency the main result is that three groups are identified in the sample each equipped with different technologies suggesting that distinct business strategies need to be adapted to the characteristics of china s hydro power companies some managerial implications are developed

optimal path for controlling co2 emissions in china a perspective of efficiency analysis this paper examines the optimal control of co2 emissions from a perspective of efficiency analysis several centralized data envelopment analysis dea models are introduced to study the optimal allocation of co2 emissions under spatial temporal and spatial temporal allocation strategies respectively the models have been used to determine the optimal paths for controlling co2 emissions at provincial and regional levels in china a sensitivity analysis of the optimal path on the emission control coefficient under spatial temporal allocation strategy is further carried out our empirical results show that more developed regions should take emission reduction responsibility earlier than less developed regions in china of the three allocation strategies spatial temporal allocation strategy seems to be a better choice for achieving the optimal control of co2 emissions at country level since it is more encompassing by allowing both timing and spatial substitutions it is also found that there exists an inverted u shape relationship between the aggregate optimal gdp and the emission control coefficient which shows that modest emission reduction policy might be more appropriate for china in order to achieve the joint goals of economic development and co2 emission reduction

the money demand function in a small open and quasi monetary economy the gambia the open economy money demand asserts that for its underlying theory to hold the variables ought to be co integrated co integrated variables although nonstationary in level can share a long term trend that is indeed stationary however the open money demand model has mainly been tested in developed and developing nations this article investigates the co integrated open economy money demand in the gambia where the macro economy is a quasi monetary system small relative to the world market but very open with a floating exchange rate regime in the co integrated space the gambian money demand appears to be quite responsive to domestic income a measure of interest rate and the real exchange rate fluctuations

good subsidies or bad subsidies evidence from low carbon transition in china s metallurgical industry abstract since the metallurgical industry has become the main source of china s carbon dioxide emissions and energy consumption in recent years low carbon transition in that industry is of great significance for achieving china s carbon reduction targets it is generally believed that phasing out fossil fuel subsidies is an effective way to reduce energy related co2 emissions since it can increase the energy prices and lower its consumption this paper aims to investigate whether the energy subsidy removal can promote the low carbon transition of china s metallurgical industry taking inter fuel and inter factor substitution effects as the link we calculate the co2 mitigation potential on the assumption that the subsidies for each category of fossil energy were eliminated we find that the metallurgical industry has a sluggish reaction to the changes in energy price supposing eliminating the energy subsidies in the period of 2003 2015 the amount of reduced co2 would be 487 286 million tons accounting for a slight proportion of the total emissions in the industry but it is meaningful for the global co2 mitigation since it approximates the whole co2 emissions in norway during the same period these findings can provide some new insights for the energy subsidy issue and suggest that the additional measures are required to promote the low carbon transition in china s metallurgical industry rather than just relying on the removal of fossil fuel subsidies

cointegration tests of a long run relation between money demand and the effective exchange rate abstract for the period starting with the floating of the us dollar we find evidence that long run stationarity of the demand function for m2 but not m1 requires inclusion of the effective exchange rate these results lend some support to mckinnon s hypothesis that nonstationarity in the demand for money can be resolved by inclusion of the exchange rate jel f41 e41

measuring total factor co2 emission performance and technology gaps using a non radial directional distance function a modified approach implementing the common but differentiated responsibilities principle for co2 mitigation requires an understanding of co2 emission performance and technology gaps in different countries this paper uses a meta frontier and non radial directional distance function to propose an alternative three stage approach to measure total factor co2 emission performance and technology gaps the first stage calculates the co2 emission performance of the group frontier the second stage uses these results to calculate the technology gap ratio the third stage integrates data from the first two stages to calculate co2 emission performance under the meta frontier this approach is easier to apply than other approaches in the literature and effectively avoids the phenomenon of the technology gap ratio being greater than unity the proposed approach can also decompose co2 emission performance loss into two categories management inefficiency and technical gaps to demonstrate the method an empirical analysis using data for 54 countries was conducted the study highlighted three main findings first upper middle income countries did not perform as well as high income countries and lower middle income countries second high income countries generally enjoy optimized production technology whereas the lower middle income countries generally had the lowest technological levels third both management inefficiency and technical gaps negatively impacted co2 emission performance but management inefficiency played a dominant role

carbon efficiency and carbon abatement costs of coal fired power enterprises a case of shanghai china abstract in this paper we adopt a non radial directional distance function to analyze the efficiency and shadow price of co2 emissions of coal fired power plants using a sample of shanghai s 20 coal fired power plants we find that the efficiency performance of power plants remained steady during the period 2007 2010 on average the carbon abatement costs of shanghai s power plants increased from 20 58 yuan ton to 39 67 yuan ton during 2007 2010 although the average shadow price of the power plants increased during the period the price was still well below shadow prices for the energy consumption of the industries and a little lower than the trading price in the ets markets in addition the paper discusses the implications of the findings

meta data envelopment analysis finding a direction towards marginal profit maximization abstract this paper discusses a new meta dea approach to solve the problem of choosing direction vectors when estimating the directional distance function the proposed model emphasizes finding the direction for productivity improvement rather than estimating the score of efficiency focusing on planning over evaluation in fact the direction towards marginal profit maximization implies a step by step improvement and wait and see decision process which is more consistent with the practical decision making process an empirical study of u s coal fired power plants operating in 2011 validates the proposed model the results show that the efficiency measure using the proposed direction is consistent with all other indices with the exception of the direction towards the profit maximized benchmark we conclude that the marginal profit maximization is a useful guide for determining direction in the directional distance function

carbon emissions performance in logistics at the city level the importance of good performance in the logistics industry contributing towards a low carbon economy is widely recognised however there are few studies on carbon emissions performance for the logistics industry especially at the city level therefore this study attempts to analyse the carbon emissions performance of the logistics industry at the city level by examining sixteen cities within yunnan province in particular the data envelopment analysis dea model and malmquist index from both the static and dynamic perspective were explored to further capture the driving factors of the carbon emissions performance in logistics the tobit model was applied to perform regression analysis the results indicate that 1 with regards to static performance two northwest cities nujiang and diqing have reached the technological frontier 2 regarding dynamic performance although six cities have improved the average dynamic logistics carbon emissions performance of all the cities decreases by approximately 5 9 from 2011 to 2015 3 in terms of driving factors the economic development factor is found to be positively and significantly related to static carbon emissions performance whereas others indicate negative and significant relationships

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

marginal abatement cost under the constraint of carbon emission reduction targets an empirical analysis for different regions in china abstract as the global climate and environmental issues become increasingly serious low carbon development has become a consensus among countries to seek new economic growth pathway as an important emitter of carbon dioxide china has put forward thirteenth five year plan tfyp outline that carbon dioxide emissions per unit of gross domestic product gdp will be 18 lower in 2020 than that in 2015 to measure the policy effects on co2 emission reduction and abatement costs the directional distance function model is introduced in this paper and the sensitivity analysis is conducted to verify the rationality of our index formulation the results show the areas with the highest carbon emission control target level have significantly higher marginal abatement costs than that of other areas in the short term the reduction targets policy effect on decreasing carbon abatement cost is not significant through sensitivity analysis we further discovered that the carbon emission reduction cost is less sensitive to the carbon emission reduction target and the impact in the short term is smaller however as time goes by the impact increases we suggest that the government should guide interregional enterprises to cooperate and play a synergistic role implementing the multilevel emission reduction targets and expanding the scope of trading in the national carbon trading market are especially important to optimize the allocation

case study on initial allocation of shanghai carbon emission trading based on shapley value abstract carbon emission trading is an effective measure to reduce greenhouse gas emissions worldwide china has publicized plans to initiate the demonstration of carbon emission trading in seven regions as of 2013 initial allocation is fundamental but it proposes difficulty in the mechanism design of the carbon emission trading system benchmark grandfathering and the shapley value have been employed to simulate a specific case which consists of the initial allocation of carbon emission allowances of three power plants in shanghai china the results of the shapley value are regarded as a theoretical equitable reference the results of benchmark are similar to those of the shapley value however it is apparent that the allocation regarding grandfathering is inequitable considering other factors we proposed the following at the introduction of experimental stage free allocation pertaining to grandfathering can be adopted meanwhile benchmark should be prepared and adopted at the appropriate time furthermore a portion of the initial allowances can be reserved for auction and this portion for auction will escalate to the extent of 100 upon entering the formal stage in addition the tiered price mechanism and the subsidy policy are also suggested

co2 emissions from electricity generation in seven asia pacific and north american countries a decomposition analysis abstract the logarithmic mean divisia index lmdi method of complete decomposition is used to examine the role of three factors electricity production electricity generation structure and energy intensity of electricity generation affecting the evolution of co2 emissions from electricity generation in seven countries these seven countries together generated 58 of global electricity and they are responsible for more than two thirds of global co2 emissions from electricity generation in 2005 the analysis shows production effect as the major factor responsible for rise in co2 emissions during the period 1990 2005 the generation structure effect also contributed in co2 emissions increase although at a slower rate in contrary the energy intensity effect is responsible for modest reduction in co2 emissions during this period over the 2005 2030 period production effect remains the key factor responsible for increase in emissions and energy intensity effect is responsible for decrease in emissions unlike in the past generation structure effect contributes significant decrease in emissions however the degree of influence of these factors affecting changes in co2 emissions vary from country to country the analysis also shows that there is a potential of efficiency improvement of fossil fuel fired power plants and its associated co benefits among these countries

efficiency based rank assessment for electric power industry a combined use of data envelopment analysis dea and dea discriminant analysis da abstract this study discusses a combined use of dea data environment analysis and dea da discriminant analysis to determine the efficiency based rank of energy firms this type of performance evaluation is important because we often have a difficulty in accessing a large sample on energy firms to derive reliable empirical results the proposed approach is useful in dealing with such a limited number of energy firms often found in previous dea studies on energy industries in the world the proposed approach uses dea to classify energy firms into efficient and inefficient groups based upon their efficiency scores then it utilizes dea da to assess their efficiency scores and ranks in this stage we can find an adjusted efficiency score for each energy firm the proposed approach provides us with the following analytical capabilities all of which cannot be found in a conventional use of dea in assessing energy firms first the proposed dea approach can avoid zero in all multipliers on efficient energy firms by incorporating scsc strong complementary slackness condition so that it can handle an occurrence of multiple reference sets and multiple projections the dea result classifies all energy firms into efficient and inefficient groups second dea da applied to the two groups evaluates all energy firms by an industry wide evaluation not depending upon a limited number of efficient energy firms in a reference set as found in a conventional use of dea the analytical capability can reduce the number of efficient energy firms third the proposed approach can provide their efficiency based ranking scores finally we can conduct a rank sum test based upon their ranking scores to obtain a statistical inference as an application this study uses the proposed approach to examine the performance of japanese electric power industry we find two economic implications one of the two implications is that no major change has occurred in the operational performance of japanese electric power industry because of japanese sluggish economy from 2005 to 2009 the other implication indicates that there are strategic differences in the operation of japanese electric power firms after the liberalization

non parametric efficiency progress and regress measures for panel data methodological aspects this purely methodological paper deals with the role of time in non parametric efficiency analysis using both fdh and dea technologies it first shows how each observation in a panel can be characterized in efficiency terms vis a vis three different kinds of frontiers i contemporaneous ii sequential and iii intertemporal these are then compared with window analysis next frontier shifts outward and inward interpreted as progress or regress are considered for the two kinds of technologies and computational methods are described in detail for evaluating such shifts in either case these are also contrasted with what is measured by the malmquist productivity index finally an alternative way of identifying progress and regress independent of the frontier notion and referring instead to some benchmark notion is extended here to panel data

a non simplistic approach to composite indicators and rankings an illustration by comparing the sustainability of the eu countries composite indicators are very popular despite being affected by several problems that often result in lack of robustness of the rankings involved the aim of this paper is to show that composite indicators can be safely used provided that rankings are built via uncertainty analysis rather than using a single composite for this purpose the approach we follow first combines different normalisation aggregation rules and weighting systems to calculate many different composites and then derives the rankings from the frequency distribution of the rankings of each competitor according to each composite such an approach appears to be a good compromise between the need for a more concise overview when looking at many variables and the loss of relevant information occurring when indicators are aggregated into a single composite indicator to illustrate the approach we rank eu countries in terms of their sustainability

income and co2 emissions evidence from panel unit root and cointegration tests abstract this paper re investigates the stationarity properties of per capita carbon dioxide co 2 emissions and real gross domestic product gdp per capita for 109 countries within seven regional panel sets covering 1971 2003 we apply the recent unit root test of the panel seemingly unrelated regressions augmented dickey fuller suradf test developed by breuer et al 2001 misleading inferences from panel unit root tests with an illustration from purchasing power parity review of international economics 9 482 493 2002 series specific unit root tests with panel data oxford bulletin of economics and statistics 64 527 546 the panel suradf test accounts for the presence of cross country correlations in the data and the parameters in the panel specification vary across countries more importantly this test allows us to identify how many and which members of the panel contain a unit root overall our empirical results illustrate that real gdp and co 2 emissions in these countries are a mixture of i 0 and i 1 processes and that the traditional panel unit root tests could lead to misleading inferences as well as the conduct of cointegration analysis being perhaps inappropriate the results of our analysis carry critical implications for the modeling of co 2 emissions and gdp because of the different orders of integration for the two variables

regional energy environmental performance and investment strategy for china s non ferrous metals industry a non radial dea based analysis globally china is the largest producer and consumer of common non ferrous metals china s non ferrous metals industry is energy intensive accounting for 24 of the total industrial energy consumption in 2011 in this study we adopted a non radial dea model to examine the energy environmental performance of the non ferrous metals industry from a regional perspective during the 2006 2011 period the energy environmental performance was evaluated by the eco efficiency under natural disposability en eco efficiency under managerial disposability em eco efficiency under natural and managerial disposability enm and enm with desirable congestion enm dc based on the en both the energy conservation and emission reduction potentials were calculated additionally the investment strategy was confirmed by regional types of damages to return dtr in the second stage study the factors influencing eco efficiency were measured using tobit regression and truncated regression models the results indicated that the efficiency scores of en em enm and enm dc were considerably different investment was effective in improving the energy environmental performance for twenty one regions during the whole study period henan had the highest energy conservation and emission reduction potentials the results obtained from the regression models were similar which displayed that the population density and energy price were responsible for the increase in eco efficiency while economic development level and industrial structure affected eco efficiency negatively based on these results policy recommendations for the non ferrous metals industry to improve their performance in a low carbon economy are suggested

analysis of energy efficiency and energy savings potential in china s provincial industrial sectors abstract because industrial sectors in china are energy intensive improving energy efficiency and promoting energy savings in these sectors are of great importance for the further sustainable development of china s economy using a proposed meta frontier data envelopment analysis dea this paper analyzes the total factor energy efficiency and energy savings potential in china s provincial industrial sectors for the years 2000 2014 from three perspectives namely the technology gap management and scale the results indicate that 1 driven by technological progress energy efficiency during the sample period was greatly improved though the expansion of technology gaps between regions and the decline in scale efficiency represented two significant handicaps 2 the current energy efficiency in china s industrial sectors remains extremely low indicating that there is considerable potential for energy efficiency improvement and energy savings and 3 the sources of energy inefficiency and energy savings potential in china s industrial sectors exhibit spatially distinct characteristics accordingly it is determined that most of china s eastern provinces should focus on improving scale and management efficiency whereas most of its central and western provinces should concentrate on three factors narrowing the regional technology gap improving management efficiency and optimizing the industrial scale
