productivity growth and environmental efficiency of the nonferrous metals industry an empirical study of china abstract this study intends to provide an insight into china s nonferrous metals industry production based on the analysis of the environmental efficiency the malmquist productivity index mpi and the malmquist luenberger productivity index mlpi the empirical experiment based on the annual data of 27 regions including provinces autonomous regions and municipalities of china during 2003 2009 shows the following results first the industry s environmental efficiency in the east area is mostly higher than that of the other area second the industry s average annual change of mpi and mlpi in china were 4 4 and 0 9 respectively this indicated that the total factor productivity growth of the industry was overestimated if undesirable outputs were ignored third the industry s productivity was mainly affected through technological advances rather than endogenous factors such as improvements in managerial practices finally during the worldwide financial crisis occurred in 2008 the industry s mlpis exceeded the mpis in most regions through measures such as adjustment of the product structure and elimination of backward production capacity

efficiency performance of current account bop flows in advanced world economies considering ghg emissions abstract current account ca imbalances reveal the unequal trade and foreign direct investment t fdi flows between various countries this paper investigates the performance of the ca component of the balance of payments bop of major advanced economies following the recent global financial and economic crisis 2013 2017 using a data envelopment analysis dea second stage approach slack based inefficiency sbi dea models are proposed using both a conventional perspective and a sustainability perspective that consider greenhouse gas ghg emissions as an undesirable output the efficiency assessment aims to identify output slacks i e exports and income inflows shortfalls as well as input slacks i e import and income outflows excesses in the second stage explanatory factors of the observed ca inefficiencies have been investigated using regression models under frequentist and bayesian frameworks although some differences exist between the conventional and sustainability scenarios regarding the negative effects of trade diversification and external debt and energy dependency on ca inefficiency in both scenarios the results indicate links between ca inefficiency and geographical regions socio economic development and the burden of customs procedures

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

a modified malmquist luenberger productivity index assessing environmental productivity performance in china abstract the malmquist luenberger m l index has been used to assess environmental productivity growth with undesirable outputs through applying directional distance function ddf to standard malmquist productivity measurement however when calculating the cross period ddfs the m l index has the same infeasibility problem as the malmquist index does to address this infeasibility problem this paper discusses when infeasibility may happen and develops a modified m l index that is based on a new ddf we propose that the modified m l index can be applied to assessing environmental performance at both macro and micro levels at a macro level we evaluate china s growth in total factor productivity tfp from 1999 to 2012 accounting for undesirable impacts the results show that technical change is the main driver of most tfp growth the tfp changes support the status quo of a distinct gap in economic development among different regions at a micro level we assess chinese auto manufacturers environmental performance from 2005 to 2012 the results suggest that chinese automakers have enjoyed a noticeable tfp improvement and that technical change is the major contributor as well taking together reducing air emissions and other pollutants is an effective way of improving environmental productivity as demonstrated the proposed modified m l index has proved to be consistently feasible and guarantees non negative reference targets for all metrics as a result we recommend the modified m l index as a robust tool for solving the infeasibility problem that is typical in conventional index and for assessing productivity under environmental impacts

energy efficiency and productivity change of china s iron and steel industry accounting for undesirable outputs abstract this paper used data from 50 enterprises in china s iron and steel industry to evaluate their energy efficiency and productivity change the study first used a conventional data envelopment analysis model and the malmquist productivity index mpi to measure the energy efficiency and productivity change over the period 2001 2008 the results indicated inefficiency in many of the plants the average energy efficiency was only 61 1 the annual growth rate of productivity was 7 96 over this period and technical change was the main contributor to this growth the research then took undesirable outputs into consideration by using the malmquist luenberger productivity index mlpi to explore the productivity change from 2006 to 2008 omitting undesirable outputs would result in biased efficiency change and technical change this paper also claimed that environmental regulation has a potentially positive impact on technical change

ecological well being performance growth in china 1994 2014 from perspectives of industrial structure green adjustment and green total factor productivity abstract industrial structure green adjustment isga and green total factor productivity gtfp deriving from development processes for green goals recently attracted great attention as two ways to achieve ecological well being performance ewp growth which is one of the main green development goals that humanity should pursue and which affects the efficiency improvement of transforming ecological consumption into human well being in this paper the effects of isga and gtfp on ewp growth are empirically tested in a dynamic panel model of spatial econometrics using statistics from 30 provinces of china in the 1994 2014 period in particular the indicator system of isga is firstly constructed based on the theories of ewp and three dimensional industrial ecological footprint 3dief the results indicate that spatial spillovers are important factors in the effects the main driving force for ewp growth in provinces of china had gradually shifted from isga to gtfp and gtfp is essential for structural bonuses from isga to take effect in addition a provincial government needs to target reference objects from not only other provinces in the same economic zone s yardstick competition but also isga and gtfp situations in geographically close or economically similar provinces in addition the adverse ewp effects of isga can be mitigated by gtfp increase or a combination of gtfp and isga for provinces in all stages of isga in general improving gtfp will be the main driving force for china s provincial ewp growth and the main venue through which the adverse effects of improper isga can be mitigated the present study contributes to explore the ewp growth effect of isga and gtfp can at least provide a valuable guidance and in depth understanding to researchers operators and policy makers who wish to improve human well being in an ecologically efficient way as well as for the follow up studies

multilateral productivity comparisons with undesirable outputs in a recent paper in this journal caves christensen and diewert i982 hereafter ccd derive what they term multilateral superlative indexes for use in the comparison of output input and productivity across economic entities the indexes derived are distinguished both by transitivity and by a high degree of characteristicity a term introduced by dreschler i 973 to refer to the degree to which the weights used in a comparison are specific to the observations being compared though the indexes are presented with the application to multicountry comparisons of output input and productivity foremost in mind the authors note that they may be useful in a number of other contexts as well i e firms and industries time series and pooled time series and cross section all of the applications mentioned or implied however have this in common they involve the comparison of productive entities all of whose outputs are sold for positive prices this is not surprising of course since most products with which economists are concerned possess this characteristic however it does render incomplete or potentially misleading the comparison of productive entities which produce significant amounts of undesirable outputs such as water and air pollution since the list of such entities is rather long and includes industries critical to many national and regional economies e g chemicals paper petroleum refining copper and steel the omission of this factor from consideration may be a matter of some importance 2 consider for example a comparison of the productivity of the steel industries

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

trade environment and development the issues in perspective abstract this special issue on trade and the environment brings together a number of papers that are constructively critical of the conventional economic wisdom on the topic we think that this criticism is warranted because of the decidely uncritical way in which free trade has been advocated in much of the literature and especially in policy the papers analyse the validity of the underlying assumptions on which the conventional wisdom is based and provide suggestions for ways to facilitate trade that is also adequately protective of the environment sustainability and other social values in this introductory piece we discuss trade the environment and sustainability summarizing arguments in the papers included in this issue and adding a few additional points not covered by them

returns to scale and damages to scale on u s fossil fuel power plants radial and non radial approaches for dea environmental assessment abstract this study proposes a new use of data envelopment analysis dea for environmental assessment paying attention to a methodological bias i e different methods produce different results dea is analytically classified into radial and non radial approaches the radial approach determines the level of unified operational and environmental efficiency by measuring an inefficiency score the score indicates the distance of a projection from an observed performance to an efficiency frontier in contrast the non radial approach determines the level of unified efficiency by measuring a total amount of slacks because each slack indicates inefficiency to avoid the methodological bias this study considers the use of radial and non radial approaches in this study we consider a production process where all organizations produce not only desirable good but also undesirable bad outputs as a result of their business operations to unify the two types of outputs this study discusses the concept of disposability which is separated into natural and managerial disposability the natural disposability indicates negative adaptation to a regulation change on undesirable outputs in contrast the managerial disposability indicates corporate strategy by which a firm considers the regulation change as a new business opportunity a firm attempts to improve its unified efficiency by utilizing new environmental technology and or new management this type of strategy indicates positive adaptation to the regulation change under the two disposability concepts this study discusses how to measure rts returns to scale under natural disposability and dts damages to scale corresponding to rts on undesirable outputs under managerial disposability the two scale measures are analytically discussed by the proposed radial and non radial approaches with scscs or without scscs where scscs indicate strong complementary slackness conditions an illustrative example on u s fossil fuel power plants indicates a policy implication that they need to introduce new technology for environmental protection this study also discusses a necessity of examining a methodological bias in energy studies empirical findings identified in this study document the practicality of the proposed approaches to measure rts dts

environmental regulations and productivity growth the case of fossil fueled electric power generation this paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973 79 business cycle a firm specific measure of regulatory intensity is developed which depends on the severity of the emission standard the extent of enforcement and the unconstrained emission rate relevant to each utility the results indicate that emission regulations result in significantly higher generating costs primarily from the increased use of low sulfur fuels the average rate of productivity growth was reduced by 0 59 percentage points per year for constrained utilities

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

dea environmental assessment on u s industrial sectors investment for improvement in operational and environmental performance to attain corporate sustainability abstract environmental assessment has recently become an important business concern because consumers are interested in environmental protection they try to avoid purchasing products from dirt imaged companies which do not pay attention to environmental protection even if their prices are much less than the ones produced by green imaged companies thus a green image is very important for corporate survivability in a global market this study considers corporate sustainability indicating that companies need to consider both economic prosperity and pollution prevention in their operations to discuss the issue from corporate strategy for modern business this study discusses a use of data envelopment analysis dea for environmental assessment by focusing upon research and development r d strategy as well as technology innovation and selection for reduction of undesirable outputs e g co 2 emission this type of research has never been explored in previous studies it is easily envisioned that the proposed dea environmental assessment will guide corporate leaders in identifying how to invest for technology innovation to reduce an amount of undesirable outputs to discuss the practicality this study applies the proposed approach to 153 observations on s p 500 corporations in 2012 and 2013 the empirical investigation confirms that investors pay more serious attention to company s green image and the reality for a long run sustainability than profitability in a short run concern furthermore the energy sector is the best investment target among seven industrial sectors examined in this study the measurement of corporate sustainability can serve as an empirical basis in selecting what type of technology is fitted for a specific industry

data envelopment analysis for environmental assessment comparison between public and private ownership in petroleum industry abstract environmental assessment recently becomes a major policy issue in the world this study discusses how to apply data envelopment analysis dea for environmental assessment an important feature of the dea environmental assessment is that it needs to classify outputs into desirable good and undesirable bad outputs because private and public entities often produce not only desirable outputs but also undesirable outputs as a result of their production activities this study proposes the three types of unification for dea environmental assessment by using non radial dea models the first unification considers both an increase and a decrease in the input vector along with a decrease in the direction vector of undesirable outputs this type of unification measures unified efficiency the second unification considers a decrease in an input vector along with a decrease in the vector of undesirable outputs this type of unification is referred to as natural disposability and measures unified efficiency under natural disposability the third unification considers an increase in an input vector but a decrease in the vector of undesirable outputs this type of unification is referred to as managerial disposability and measures unified efficiency under managerial disposability all the unifications increase the vector of desirable outputs to document their practical implications this study has applied the proposed approach to compare the performance of national oil firms with that of international oil firms this study identifies two important findings on the petroleum industry one of the two findings is that national oil companies under public ownership outperform international oil companies under private ownership in terms of unified operational and environmental efficiency and unified efficiency under natural disposability however the performance of international oil companies exhibits an increasing trend in unified efficiency the other finding is that national oil companies need to satisfy the environmental standard of its own country while international oil companies need to satisfy the international standard that is more restricted than the national standards as a consequence international oil companies outperform national oil companies in terms of unified efficiency under managerial disposability

estimating the environmental efficiency productivity and shadow price of carbon dioxide emissions for the belt and road initiative countries abstract this study investigates the environmental efficiency productivity and shadow price of carbon dioxide co2 emissions of 52 belt and road initiative bri countries for 2005 2016 we consider the case of three inputs energy labor and capital one desirable output gdp and one undesirable output co2 emissions the contribution of this paper is that we use the endogenous directional distance function ddf to construct environmental efficiency and sequential productivity indicators the benefit of this approach is that we can both avoid the influence of arbitrary mapping rules and capture the progressive nature of the technology the results show that the technical efficiency of eastern asia increased continuously during the sample period while those of the other regions did not show a significant trend indicating that eastern asia was catching up with the frontier faster than the rest of the regions the average shadow prices of co2 emissions for all the bri countries increased steadily over the sample period but the shadow prices of eastern europe and central asia are much higher than those of the other regions the average productivity of the bri countries improved for most periods mainly because of technological progress moreover the technical changes for the six regions during the sample period are all positive meaning that technology progress is universal for the bri countries especially for those in eastern asia the results of this study have important policy implications for carbon reduction in the bri countries

effects of changes in the discount rate on the foreign exchange value of the dollar 1973 to 1978 this paper attempts to analyze the effects of changes in the federal reserve s discount rate on the dollar s foreign exchange value if a discount rate increase were to signal a subsequent general increase in market interest rates one would expect u s dollar denominated assets to become relatively more attractive and the ensuing increased demand for dollar assets to tend to raise the dollar s exchange value the reverse would be true for discount rate decreases however in recent years the federal reserve s policy of moving the discount rate with a lag behind the federal funds rate means that market participants generally have sufficient information to anticipate changes in the discount rate when this is the case announcement effectsimmediate and discernible market responses to discount rate changes do not occur under special circumstances in 1978 however announcement effects could and did occur by increasing the discount rate when the federal funds discount rate differential was around normal levels and by increasing the discount rate by a larger amount than the market anticipated the federal reserve used the discount rate as a signal to market participants that it would use other operating instruments to bring about changes in market interest rates and the monetary base in their 1977 article raymond e lombra and raymond g torto ran a number of econometric tests for discount rate exogeneity on monthly data from january 1968 to may 1974 they concluded that discount rate movements were not independent of the spread between the discount rate and the federal funds rate given rational expectations therefore changes in the discount rate could not generate announcement effects lombra and torto 1977 this paper updates the work of lombra and torto and then attempts to test directly

the reaction of stock prices to unanticipated changes in money a note much of the past work on the money stock market relationship centered on the question of whether money is a leading indicator of stock prices studies by sprinkel 22 homa and jaffee 10 and hamburger and kochin 8 supported the view that past increases in money lead to increases in equity prices the implication of this work was that investors could earn above normal proflts by using a trading strategy based on the observed behavior of the money stock this contradicts the efficient markets hypothesis which asserts that current asset prices reflect all available information so that no such trading strategy can exist subsequent research by cooper 3 pesando 17 rozeff 21 and rogalski and vinso 19 has shown that past money changes do not contain predictive information on stock prices upholding the efficient markets view this paper investigates whether the response of common stock prices to weekly money announcements is consistent with the efflcient markets hypothesis unlike the above research therefore the focus is on the very short run response of stock prices to both anticipated and unanticipated announced changes in money recent work by berkman 1 grossman 7 urich and wachtel 25 and roley 20 indicates that short term interest rates respond only to the unexpected component of the announcement with short term rates rising when the announced change in money exceeds the expected change berkman also examined the reaction of stock prices finding that an unanticipated increase in the money supply depressed share prices lynge 13 found that positive money announcements lowered stock prices but since he did not distinguish expected from unexpected money growth his results do not bear directly on the efficient markets issue in investigating the response of stock prices to weekly money announcements survey data on market participants forecasts of the announced weekly change

stock prices and economic news this paper examines the daily response of stock prices to announcements about the money supply inflation real economic activity and the discountrate except for the discount rate survey data on market participants expectations of these announcements are used to identify the unexpected component of the announcements in order to test the efficient markets hypothesis that only the unexpected part of any announcement the surprise moves stock prices the empirical results support this hypothesis and indicate further that surprises related to monetary policy significantly affect stock prices there is only limited evidence of an impact from inflation surprises and no evidence of an impact from real activity surprises on the announcement days there is also only weak evidence of stock price responses to surprises beyond the announcement day this abstract was borrowed from another version of this item

environmentally sensitive productivity growth a global analysis using malmquist luenberger index abstract we examine conventional and environmentally sensitive total factor productivity tfp in 41 developed and developing countries over the period of 1971 to 1992 due to the non availability of reliable input and co 2 emissions price data the study uses directional distance function to derive malmquist luenberger ml productivity index the index allows us to decompose the tfp into measures of technical and efficiency changes dea is used to compute the directional distance functions we find that tfp index value is not different when we account for the co 2 emissions relative to the situation when they are freely disposable but for the components of tfp change technical and efficiency changes the null hypothesis of whether the indexes are the same under two different scenarios cannot be accepted issues of catch up and convergence or in some cases possible divergence in productivity are examined within a global framework the paper also studies the impact of openness on conventional and environmentally sensitive measures of productivity

heterogeneous technologies strategic groups and environmental efficiency technology gaps for european countries abstract this paper measures technology tg and environmental efficiency technology gaps eetgs in 25 european countries over two distinct periods 2002 and 2008 examining the possible effect of adopted environmental regulations and the kyoto protocol commitments on environmental efficiency technology gaps however the introduction of the metafrontier in our analysis puts into our discussion the role of heterogeneous technologies and its effect on the above mentioned measures employing a directional distance function we investigate whether there is an actual difference in terms of environmental efficiency and efficiency performance among european countries considering the technological frontiers under which they operate the construction of individual frontiers has been realized employing a large number of variables that are highly correlated with countries learning and absorbing capacity new technological knowledge and using economic theory and classical frontier discrimination like developed vs developing north vs south and participation in the eurozone or not the overall results indicate a crucial role of heterogeneous technologies for technology gaps in both periods moreover a significant decrease for both measures although in different percent has been recorded emphasizing the key role of knowledge spillovers

environmental assessment for corporate sustainability by resource utilization and technology innovation dea radial measurement on japanese industrial sectors abstract this study proposes a new use of dea data envelopment analysis radial approach to examine the corporate sustainability of japanese industrial sectors the concept of corporate sustainability is measured by its subcomponent measures including uen unified efficiency under natural disposability uem unified efficiency under managerial disposability uenm unified efficiency under natural and managerial disposability uei unified efficiency for intermediate measurement and uenm dc unified efficiency under natural and managerial disposability with desirable congestion among the five measures the uei examines a degree of how each firm can efficiently utilize its resources the uenm dc examines a degree of how the firm can reduce an amount of undesirable outputs by technology innovation and or managerial change such a combined use between uei and uenm dc has been never explored in dea environmental assessment the empirical results obtained from the proposed approach have identified two important implications one of the two implications is that the japanese energy industry has been long under governmental regulation so that energy firms do not have corporate governance capabilities at the level of other industrial sectors which are competing in a global market in particular the implication is applicable to japanese electric power firms it is necessary for them to change their corporate governances e g by adding new executive board members who have international experience and or woman executives as widely found in american and european energy industries so that they can pay attention to consumers not regulatory agencies of the japanese government the other implication is that technology innovation can more effectively improve the performance of the energy sector employing high efficiency and low carbon generation technologies to achieve desirable fuel mix is essential for improving the corporate sustainability of the japanese energy sector

transport and co2 productivity growth and carbon dioxide emissions in the european commercial transport industry in the last decades transport activities persistently increased in the eu27 and were strongly coupled to growth in gross domestic product like most production processes they are inevitably linked with the generation of environmentally hazardous by products such as co2 emissions this leads to the question of how to promote a sustainable transport sector that meets both environmental protection targets and economic requirements in this context the objective of this paper is to compare the co2 sensitve productivity development of the european commercial transport industry for the period between 1995 and 2006 we calculate a malmquist luenberger productivity index to investigate the effects of country specific regulations on productivity and to identify innovative countries our results show a high variation in the co2 sensitive productivity development and a slight productivity decrease on average efficiency losses indicate that the majority of the countries were not able to follow the technological improvements induced by some innovative countries

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

did china s regional transport industry enjoy better carbon productivity under regulations despite rapid economic development the transport industry has been claimed to account for a major part of climate change this paper investigates total factor carbon sensitive productivity growth in the regional transport sector in china and decomposes its dynamic changes over time taking account of the regional heterogeneity of different provinces thus the contemporaneous metafrontier malmquist luenberger approach that combined with non radial directional distance functions is proposed and define a new indicator called the contemporaneous metafrontier malmquist luenberger carbon emission performance index cmml this total factor indicator includes the metafrontier efficiency change index mec the metafrontier technology change index mtc and the metafrontier technology gap change index tgc results show an about 4 increase in overall total factor carbon emission productivity during the period of 2000 2012 different growth patterns are also observed in the transport sector across different area of china in the eastern region the growth of carbon productivity is driven mainly by pure efficiency changes whereas the central region is driven mainly by innovations in the low carbon transport technology

co2 emissions reduction of chinese light manufacturing industries a novel ram based global malmquist luenberger productivity index climate change has become one of the most challenging issues facing the world chinese government has realized the importance of energy conservation and prevention of the climate changes for sustainable development of china s economy and set targets for co2 emissions reduction in china in china industry contributes 84 2 of the total co2 emissions especially manufacturing industries data envelopment analysis dea and malmquist productivity mp index are the widely used mathematical techniques to address the relative efficiency and productivity of a group of homogenous decision making units e g industries or countries however in many real applications especially those related to energy efficiency there are often undesirable outputs e g the pollutions waste and co2 emissions which are produced inevitably with desirable outputs in the production this paper introduces a novel malmquist luenberger productivity mlp index based on directional distance function ddf to address the issue of productivity evolution of dmus in the presence of undesirable outputs the new ram range adjusted measure based global mlp index has been applied to evaluate co2 emissions reduction in chinese light manufacturing industries recommendations for policy makers have been discussed

dea radial measurement for environmental assessment and planning desirable procedures to evaluate fossil fuel power plants abstract energy policy depends on a proper use of methodology in guiding a large energy issue such as the global warming and climate change dea is one of such methodologies that are often used for preparing environmental policy which is closely linked to various energy issues unfortunately the use of dea applied to environmental policy is insufficient often misguiding policy makers and other individuals who are involved in energy issues this study provides three guidelines for a use of dea in preparing environmental assessment first it is important to prepare both primal and dual formulations to confirm whether information regarding all production factors i e inputs desirable and undesirable outputs is fully utilized in dea assessment second dea has model variations in radial and non radial measurements it is necessary for us to examine environmental issues by different models in order to avoid a methodological bias existing in those empirical studies finally dea environmental assessment needs to incorporate the concept of natural and managerial disposability the natural disposability indicates that a firm negatively adapts a regulation change on undesirable outputs in contrast the managerial disposability indicates that a firm positively adapts the regulation change because the firm considers the regulation change as a new business opportunity

on the inconsistency of the malmquist luenberger index abstract apart from the well known weaknesses of the standard malmquist productivity index related to infeasibility and not accounting for slacks already addressed in the literature we identify a new and significant drawback of the malmquist luenberger index decomposition that questions its validity as an empirical tool for environmental productivity measurement associated with the production of bad outputs in particular we show that the usual interpretation of the technical change component in terms of production frontier shifts can be inconsistent with its numerical value thereby resulting in an erroneous interpretation of this component that passes on to the index itself we illustrate this issue with a simple numerical example finally we propose a solution for this inconsistency issue based on incorporating a new postulate for the technology related to the production of bad outputs

asset returns discount rate changes and market efficiency the primary purpose of this paper is to reconcile the previous findings of discount rate endogeneity with the presence of discount rate announcement effects in securities markets the crux of this reconciliation is the distinction between technical discount rate changes that are endogenous and nontechnical changes which contain some informative policy implications in essence we attempt to separate expected discount rate changes from unexpected changes or equivalently the expected component of discount rate changes from the unexpected component if markets are efficient the former should have no announcement effects while the latter may be associated with an announcement effect accordingly the focus of the empirical analysis is on the interaction between discount rate exogeneity the specific monetary policy regime and accouncement effects in addition we examine whether the behavior of these markets in the postannouncement period is consistent with the rapid price adjustment implied by market efficiency

evaluating environmental performance using data envelopment analysis the case of european countries abstract environmental efficiency is considered to be a critical pillar of sustainable development consequently improving environmental performance has aroused attention at both the local and global level this study evaluated the environmental performance of european union eu countries using the data envelopment analysis dea approach and the global malmquist luenberger index although literature using the dea approach to measure environmental performance exists this study s main contribution was considering different types of undesirable outputs and using long term panel data on eu countries in particular the dea window analysis technique was applied to evaluate the environmental performance of 27 eu countries in cross sectional and time varying data during the period 2000 2017 three dea models were examined labor capital and energy were used as common inputs with a combination of different outputs including gross domestic product carbon dioxide and particulate matter emissions and waste the empirical results revealed that the trends in the environmental performance of the entire eu and its individual countries were similar under all examined models environmental performance was indeed negatively affected by the financial crisis of 2007 2008 this impact was mainly observed in eastern eu countries furthermore both economic and environmental variables significantly influenced countries overall efficiency the analysis using the global malmquist luenberger index elucidated that overall eu countries experienced the efficiency improvement during the study period although fluctuations were observed these results enable countries and policymakers to understand their environmental performance identify strengths and weaknesses and set targets for further improvement based on the current best practices of comparable peers

carbon sensitive meta productivity growth and technological gap an empirical analysis of indian thermal power sector abstract this paper measures carbon sensitive efficiency and productivity growth in technologically heterogeneous coal fired thermal power plants in india for the period of 2000 to 2013 it uses a unique data set of 56 plants obtained petitioning the right to information act 2005 we apply within mle fixed effects stochastic frontier model to get consistent estimates of meta directional output distance function the thermal power plants are grouped into two categories central sector and state sector we find that the state sector plants have higher potential to simultaneously increase electricity generation and reduce carbon emissions than the central sector plants if all the state and central sectors plants were made to operate on the meta frontier reduction of 98 million tonnes of co2 could have been achieved carbon sensitive productivity growth in the central sector plants is higher than the plants in state sector though in both the sectors productivity growth is governed by carbon sensitive innovation effect commercialisation or autonomy in electricity generation also induces carbon sensitive productivity growth and reduces carbon sensitive productivity growth gap

returns to scale and damages to scale under natural and managerial disposability strategy efficiency and competitiveness of petroleum firms environmental assessment recently becomes a major policy issue all over the world this study discusses how to use data environment analysis dea for environmental assessment for planning corporate strategy and international competitiveness an important feature of dea environmental assessment is that it classifies outputs into desirable good and undesirable bad outputs because all private and public entities produce not only desirable outputs but also undesirable outputs as a result of their production activities this study proposes the two types of output unification for dea environmental assessment by using a non radial model one of the two output unifications is that it considers a decrease in an input vector along with a decrease in the vector of undesirable outputs this type of unification is referred to as natural disposability the other unification considers an increase in an input vector but a decrease in the vector of undesirable outputs this type of strategy is referred to as managerial disposability both unifications increase the vector of desirable outputs after developing the two concepts on disposability this study theoretically explores how to measure returns to scale rts under natural disposability and damages to scale dts under managerial disposability to document the practicality of the proposed approach this study applies it to compare the performance of national oil firms with that of international oil companies this study identifies four important findings on the petroleum industry first national oil companies outperform international oil companies in the unified efficiency under natural disposability second international oil companies outperform national oil companies in the unified efficiency under managerial disposability third national oil firms exhibit a mixed result on rts while international oil firms exhibit decreasing rts finally both national and international oil companies exhibit increasing dts implying that all oil firms need to decrease their operational sizes for improving their environmental performance on co2 emission as an alternative strategy the result suggests that they need to introduce technology innovation e g clean air technology into their business operations the technology based strategy has more practicality than the size reduction in their operations

journey for green development transformation of china s metal industry a spatial econometric analysis abstract the metal industry mi in china is energy and emissions intensive this paper tries to provide guidance for the green development transformation of china s mi by investigating the green total factor productivity gtfp and its influencing factors using a global data envelopment analysis and a spatial tobit regression model the estimation results show that 1 from 2000 to 2015 gtfp of china s mi enjoyed a considerable improvement however the current value of gtfp of china s mi is still less than 0 5 indicating that gtfp of china s mi is far from efficient 2 the spatial correlation test shows that gtfps of china s provincial mis have positive spatial correlations most of the provinces scattered in high high and low low agglomerations 3 gtfp of china s mi is significantly positive related to the degree of marketization fiscal decentralization environmental regulation industrial scale is significantly negative related to resources endowment and product structure and has u shaped relationship with the level of economic development the above results suggest that china already has made remarkable achievements in promoting green development of its mi however there is much room for further improvement policy options for the green development transformation of china s mi include but are not limited to promoting market oriented and financial system reforms strengthening environmental supervision and optimizing industrial scale and product structure finally recommendations for the effective implementation of these policies are provided at the end of the study

an analysis of spain s global and environmental efficiency from a european union perspective abstract sustainable economic growth from the environmental point of view is one of the commitments of the eu 28 different measures have been implemented to deal with this issue this work analyses spain s natural efficiency and management efficiency in their static and dynamic sense for the years 2005 2012 in comparison eu 28 the analysis has been carried out using the malmquist index and natural and managerial efficiency three variables have been considered as inputs work gross fixed capital formation and final energy consumption two variables are the outputs the gdp as a desirable output and greenhouse effect gas emissions as an undesirable output the result is that spain s managerial efficiency and natural efficiency are though their values are lower evolving in a similar manner to those of the countries which have been at the heart of the eu longer these levels of efficiency are higher than those of the block of countries which have joined the eu 28 more recently the natural malmquist index results indicate that these are the countries which have had a greater growth in productivity above spain s and the average of the more veteran countries

four decades of terms of trade booms a metric of income windfall we study latin america s history of terms of trade booms during the period 1970 2012 through the prisms of a metric that quantifies the associated exogenous income shock income windfall we also document saving patterns during these episodes and propose a measure of how much of the income windfall was saved i e the marginal saving rate we find that latin america s terms of trade shock of the last decade has not differed much in magnitude from that observed during the 1970s but the associated income windfall has been substantially larger while aggregate saving increased more than in past episodes the share of the windfall saved has been lower suggesting that greater aggregate savings reflect mainly the sheer size of the exogenous income shock rather than a greater effort to save it

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

decomposition of the environmental inefficiency of the meta frontier with undesirable output abstract in this paper we present an alternative analysis framework to evaluate the effects of technology heterogeneities and undesirable output on environmental efficiency measurement the proposed framework combines the directional distance function and a meta frontier analysis it can be used to measure efficiency improvements brought about by enhanced technical management and technological advances for demonstration purposes we used the framework to measure the environmental efficiency in 90 countries worldwide for the 2003 2007 period the results showed that when the meta technology set is used as the evaluation basis the average environmental efficiency of high competitiveness countries is greater than that of lower middle low and upper middle competitiveness countries the upper middle competitiveness countries perform worse than the lower middle and low competitiveness countries because of the excessive labor force usage and carbon dioxide emissions in these countries we also found that the environmental inefficiency of the meta frontier for high competitiveness countries can be attributed to managerial failure in the production process whereas that for upper middle lower middle and low competitiveness countries can be attributed to technological differences

environmental assessment by dea radial measurement u s coal fired power plants in iso independent system operator and rto regional transmission organization abstract the economic concept of weak and strong disposability on undesirable outputs dominated the previous discussions on dea data envelopment analysis radial measurement for environmental assessment this study reexamines the economic concept from the perspective of corporate strategies on how to adapt a regulation change on undesirable outputs the economic concept of disposability conventionally accepted by production economists is replaced by natural and managerial disposability in this study the natural disposability implies an environmental strategy that a firm attempts to decrease an input vector to reduce a vector of undesirable outputs given the decreased input vector the firm attempts to increase a vector of desirable outputs as much as possible this type of strategy indicates negative adaptation meanwhile 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 on undesirable outputs as a new business opportunity a firm attempts to improve its unified operational and environmental performance by utilizing new technology and or new management the strategy indicates positive adaptation considering the two types of disposability this study discusses how to measure unified efficiency under natural and managerial disposability by dea radial models to document the practicality of the proposed dea environmental assessment this study applies it to compare the performance of u s coal fired power plants under isos rtos independent system operators regional transmission organizations with that of the other power plants not belonging to any organization this study identifies two empirical findings one of the two findings is that the latter coal fired power plants outperform the former power plants belonging to isos rtos in terms of three efficiency measures this result indicates that isos and rtos do not provide an effective coordination for coal fired power plants at the level that can be found in the other power plants the other finding is that there is technological improvement in the operation of coal fired power plants

market response to the weekly money supply announcements in the 1970s the hypothesis that the weekly announcement of the money supply affects interest rates is examined the announcement effect is interpreted as a policy anticipation effect that is an unanticipated increase in the money supply leads to an increase in interest rates in anticipation of future tightening by the federal reserve estimates of this effect with proxies for the unanticipated change constructed from a survey of money supply forecasts and an arima model indicate that a financial markets respond very quickly to the announcement and b the response was largest when policymakers emphasized the importance of the monetary aggregates financial market participants are careful observers of the weekly money supply announcement and generally agree that the announcement often leads to changes in interest rates this occurs because the announcement leads market participants to revise their expectations both of future federal reserve policy actions and of future economic conditions in this paper we examine the response of yields on treasury bills to the announcement of the money supply and the extent to which that response has varied in the last ten years money supply announcements may affect market interest rates in three ways first actual expansion of the money supply leads to lower interest rates through a liquidity effect however rapid monetary growth which is not anticipated leads market participants to expect the federal reserve to counteract such growth in the future as a consequence there may be a policy anticipation effect which causes higher interest rates in anticipation of future tightening furthermore prolonged rapid monetary growth also creates inflation and inflationary expectations which lead to higher interest rates thus there may exist a third effect the inflationary expectations effect which also leads to higher interest rates our interest in this paper is in the immediate market response to the weekly announcement of the money supply which as we argue below is most likely to be a policy anticipation effect the policy anticipation effect is best described by example suppose that the announced change in the money supply exceeds that which was expected by

measurement of environmentally sensitive productivity growth in korean industries this study measures productivity growth using the metafrontier malmquist luenberger productivity growth index mml index method and decomposes the index the results are compared with those obtained from the conventional malmquist luenberger ml productivity growth index mml has two advantages compared with the ml index the former is able to consider undesirable output as a by product of production which accounts for producer group heterogeneities as a result it enables separation and estimation of changes in the technological gap between regional and global frontier technologies the proposed index is employed to measure productivity growth and decompose its components in 14 korean industrial sectors during the period between 1981 and 2007 for the purpose of detailed analysis of policy effects the study period was divided into three decades the results show that technology innovation can be regarded as a more important factor of productivity growth rather than efficiency change the chemical and petrochemical machinery and transport equipment industries are treated as global innovators in the whole period however the result differs according to decades it is found that the groups with higher energy efficient technology and profitability obtain a higher productivity growth rate in comparison with their low energy efficient technology industry counterparts policy implications of the empirical results are discussed

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

investment strategy for sustainable society by development of regional economies and prevention of industrial pollutions in japanese manufacturing sectors abstract a balance between industrial pollution prevention and economic growth becomes a world wide issue to develop a sustainable society in many industrial nations to discuss the issue this study proposes a new use of dea environmental assessment to determine how to effectively allocate capital for developing regional industries the amount of capital is used to invest for technology innovation for both local economic growth and environmental protection in this study the proposed approach separates outputs into desirable and undesirable categories inputs are also separated into two categories one of which indicates an amount of investment on capital assets the other category is used for production activities the proposed approach unifies them by two disposability concepts this study has evaluated the performance of manufacturing industries in 47 prefectures local government units in japan by unified efficiency under natural disposability uen unified efficiency under managerial disposability uem and unified efficiency under natural and managerial disposability uenm the uenm is further separated into its two cases with and without a possible occurrence on desirable congestion or technology innovation on undesirable outputs this study has empirically confirmed that japanese manufacturing industries need to make their efforts to reduce greenhouse gas emissions and air pollution substances by investing in technology innovation furthermore most of economic activities are currently located at metropolitan regions e g tokyo in japan to develop a sustainable society japan needs to allocate capital into regions with a high level of investment effectiveness by shifting the manufacturing industries from the metropolitan regions to much promising local areas identified in this study such a shift along with technology innovation makes it possible to reduce air pollutions in the entire japan by balancing economic growth and pollution prevention this empirical study confirms that the proposed approach is useful in both guiding regional planning and developing a sustainable society it is easily envisioned that the proposed approach is useful for not only japan but also the other industrial and developing nations

issue in pollution control interplant cost differences and economies of scale debate on interplant pollution control cost differences focuses on the question of whether a system of taxes or transferable discharge permits should require those plants with low treatment costs to control a higher share of effluents another issue under debate is whether those industries with a large minimum size may be effectively barred by pollution control requirements evidence of the inefficiency of present institutional arrangements is shown by studying production function estimations of 30 pulp and paper mills in wisconsin and michigan a more efficient reallocation of pollution control resources could be effected with more market oriented regimes 58 references 6 tables dck

a sequential malmquist luenberger productivity index environmentally sensitive productivity growth considering the progressive nature of technology this study proposes an index for measuring environmentally sensitive productivity growth which appropriately considers the nature of technical change the rationale of this methodology is to exclud

dea environmental assessment in time horizon radial approach for malmquist index measurement on petroleum companies abstract the climate change and various pollutions have been influencing our societies and economies the environmental assessment to be discussed in this study is increasingly important because it serves as an initial step toward pollution prevention corporate leaders policy makers researchers and individuals who are interested in environmental protection have been paying attention to the assessment so that they can prepare policy suggestions on the global warming and climate change as a methodology for the assessment this study proposes a use of data environment analysis dea in a time horizon most of data sets on the climate change are sampled in a time series where the performance of organizations fluctuates every moment in applying the dea environmental assessment to such a data set it is necessary for us to classify outputs into desirable e g oil production and undesirable e g co 2 emission categories because all organizations usually produce not only desirable but also undesirable outputs as a result of their economic activities to unify the two different types of outputs this study incorporates the concept of natural and managerial disposability into the computational framework of dea and extends them into a time horizon for the research purpose this study incorporates malmquist index into the proposed dea environmental assessment to examine an occurrence of a frontier shift among multiple periods the frontier shift indicates a technology progress and or managerial innovation during an observed period the index is further separated into four subcomponents in a time horizon these subcomponents are differently expressed under the natural and managerial disposability thus eight different subcomponents on the malmquist index are proposed to measure the frontier shift as an application this study uses the proposed dea approach to examine whether the frontier shift due to technology progress occurs or not in the petroleum industry from 2005 to 2009 our empirical study finds that the industry has not exhibited any major frontier shift under natural disposability but showing a considerable frontier shift under managerial disposability in other words the petroleum firms have improved their environmental performance by eco technology to reduce an amount of co 2 emission during the observed annual periods

controlling monetary aggregates the discount window this paper argues that current discount window policy coupled with non borrowed reserve targeting of the federal reserve makes the quantity of high powered money endogenous examination of the advisability of this procedure in a stochastic environment is conducted using a general equilibrium financial model it is concluded that the current policy reduces the destabilizing effects of shifts between various depository financial assets but increases the effect of other asset portfolio shifts and aggregate supply disturbances these results are consistent with the work of poole inasmuch as the current debate over discount policy is a repackaging of the debate over interest rate or aggregates control for monetary policy

dea environmental assessment in a time horizon malmquist index on fuel mix electricity and co2 of industrial nations abstract climate change and global warming become a major policy issue in the world economic activities produce not only desirable outputs e g electricity but also undesirable outputs e g co 2 emission the important policy issue is how each nation can balance between economic development and environmental protection to attain a sustainable society in attaining the sustainable society environmental assessment is increasingly important because it can serve as an initial step toward the green growth of each nation for the purpose this study proposes a new use of dea data environment analysis for environmental assessment in a time horizon the proposed use of dea incorporates malmquist index to examine the degree of a frontier shift among multiple periods the frontier shift indicates a technology progress and or managerial innovation during an observed period the index is conceptually separated into six subcomponents which are further divided into twelve different subcomponents six subcomponents two disposability concepts under the natural and managerial disposability in the index measurement it is necessary for us to consider a frontier crossover among different periods because technology innovation usually has a time lag until it really appears as an empirical application this study utilizes the proposed approach to identify the relationship among fuel mix electricity and co 2 of ten industrial nations this study finds three important empirical findings first there is a time lag in technology innovation on electricity generation and co 2 emission reduction consequently it is necessary to consider the existence of a frontier crossover in assessing the electric power industry second nuclear generation as found in france as well as hydro and renewable energy as found in netherlands are important for the development of a sustainable society although the former is associated with a very high level of risk and the latter has a limited generation capacity finally the electric power industry has been making a corporate effort to reduce the amount of co 2 emission by utilizing nuclear and renewable energy

increasing agricultural productivity while reducing greenhouse gas emissions in sub saharan africa myth or reality the motivation for this study stems from two major concerns that are interlinked the first is the decades long food insecurity crisis faced by sub saharan african ssa countries which is still prevalent the second is the negative impact greenhouse gas ghg emissions from agriculture may have on future food production and which is likely to worsen the food insecurity problem the conundrum ssa farmers face is how to increase food output through productivity growth while minimizing ghg emissions to measure changes in productivity growth and ghg emissions this study evaluates the agricultural performance of 18 ssa countries by utilizing the malmquist luenberger index to incorporate good and bad outputs for the years 1980 2012 the empirical evidence demonstrates that productivity is overestimated when bad outputs are not considered in the production model the analysis provides a better understanding of the effectiveness of previous mitigation methods and which informs an appropriate course of action needed to achieve the twin objectives of increasing agriculture productivity while reducing ghg emissions

environmental regulation and environmental productivity the case of china abstract constrained by the dual mission of supporting industrial growth and reducing emissions china s traditional emission reduction oriented environmental policies unavoidably face a dilemma this study adopts the gml index to calculate china s industrial productivity by considering environmental factors in addition based on the assumption of industry heterogeneity the author examines the non linear relationship between china s environmental regulation and environmental productivity and calculated the optimal regulation environment for industries according to this study when impact of undesirable outputs pollutant emissions is considered environmental regulation and environmental productivity are positively correlated which to some degree validates the porter hypothesis at present environmental regulation has significant positive effects on clean production industries but shows a lag effect on pollution intensive industries the degree of environmental regulation and environmental productivity show an inverted u shaped relation and display three thresholds it should be noted however that the relationship between regulation and productivity may vary across industries these findings have clear policy implications rather than continually increasing the level of environmental regulation the government should establish standards for individual industries that emphasize flexibility

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

productivity growth and environmental regulations accounting for undesirable outputs analysis of china s thirty provincial regions using the malmquist luenberger index this paper employs the malmquist luenberger ml productivity index to evaluate china s growth in total factor productivity tfp incorporating undesirable outputs during the period from 1989 to 2008 the ml productivity index and its components technical and efficiency changes are derived from the directional distance function which gives credit for an increase in good outputs and for reductions in undesirable outputs the average annual ml productivity growth accounting for undesirable outputs is 2 46 whereas the value of the traditional malmquist productivity index is 4 84 showing that the true tfp growth in china is overestimated if undesirable outputs are ignored we explore the strictness in enforcing environmental regulations and its impact on improvements in ml productivity the results show that the enforcement of environmental regulations in china is in general far below the levels achieved in the best performing regions and that the more stringent enforcement of environmental regulations would help to improve ml productivity growth in china

productivity growth environmental regulation and win win opportunities the case of chemical industry in italy and germany abstract this paper analyzes the environmental and economic efficiency of a sample of firms located in italy and germany operating in the chemical sector and included in the european pollution release and transfer register e prtr the directional distance function ddf approach in a conditional setting has been applied to obtain efficiency score and total factor productivity tfp growth indexes considering pollution in computations emissions increase in absolute term between 2004 and 2007 with a worse performance of italian firms but efficiency indicators show a reduction of inefficiency over time with similar performance of firms from the two countries the formal test for the porter s hypothesis suggests that chemical firms suffering higher compliance costs in the first period react with investment increasing productivity in the following years the empirical evidence robust to different specifications and estimation methods supports the presence of win win opportunities

environmental productivity and kuznets curve in india abstract as a result of india s extremely rapid economic growth the scale and seriousness of environmental problems are no longer in doubt whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management because it influences the cost of alternative production and pollution abatement technologies in this study we use state level industry data of sulfur dioxide nitrogen dioxide and suspended particular matter over the period 1991 2003 employing recently developed productivity measurement technique we show that overall environmental productivities decrease over time in india furthermore we analyze the determinants of environmental productivities and find environmental kuznets curve type relationship existences between environmental productivity and income panel analysis results show that the scale effect dominates over the technique effect therefore a combined effect of income on environmental productivity is negative

measuring environmental efficiency of industry a case study of thermal power generation in india technical and environmental efficiency of some coal fired thermal power plants in india is estimated using a methodology that accounts for firm s efforts to increase the production of good output and reduce pollution with the given resources and technology the methodology used is directional output distance function estimates of firm specific shadow prices of pollutants bad outputs and elasticity of substitution between good and bad outputs are also obtained the technical and environmental inefficiency of a representative firm is estimated as 0 06 implying that the thermal power generating industry in andhra pradesh state of india could increase production of electricity by 6 while decreasing generation of pollution by 6 this result shows that there are incentives or win win opportunities for the firms to voluntarily comply with the environmental regulation it is found that there is a significant variation in marginal cost of pollution abatement or shadow prices of bad outputs across the firms and an increasing marginal cost of pollution abatement with respect to pollution reduction by the firms this result calls for the use of economic instruments like pollution taxes instead of command and control regulation used currently in india to reduce air pollution

the structure of expectations of the weekly money supply announcement abstract this paper examines the structure of expectations of the weekly money supply announcement in the late 1970s the data used are from a weekly telephone survey of money market participants the rationality and structure of expectations are explored with the data organized in three ways the mean response to each weekly survey the pooled sample of individual responses and time series of responses by each individual in the survey the effect of data aggregation on rationality tests is investigated the structure of the expectations data are also examined and it is found that both strong regressive influences and adaptive learning characterize the data

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

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

environmentally sensitive productivity analysis of the canadian pulp and paper industry 1959 1994 an input distance function approach abstract this study employs a parametric input distance function that incorporates both desirable and undesirable outputs to provide a more complete representation of the production technology from which environmentally sensitive productivity and efficiency measures can be generated this framework also generates pollution abatement cost estimates that are useful for policy making an input based malmquist index of productivity growth that appropriately credits the producer not only for increases in marketable or desirable outputs but also for the production of improved environmental quality through pollution abatement activities is derived from the input distance function the method was applied to time series data from the canadian pulp and paper industry our shadow price estimates indicate that the marginal cost to producers of pollution control has been rising the main conclusion of this study is that productivity improvement from the social viewpoint has been stronger than conventional measures would suggest

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
