environmental taxation inequality and engel s law the double dividend of redistribution empirical evidence shows that low income households spend a high share of their income on pollution intensive goods this fuels the concern that an environmental tax reform could be regressive we employ a framework which accounts for the distributional effect of environmental taxes and the recycling of the revenues on both households and firms to quantify changes in the optimal tax structure and the equity impacts of an environmental tax reform we characterize when an optimal environmental tax reform does not increase inequality even if the tax system before the reform is optimal from a non environmental point of view if the tax system before the reform is calibrated to stylized data and is thus non optimal we find that there is a large scope for inequality reduction even if the government is restricted in its recycling options

pigou meets mirrlees on the irrelevance of tax distortions for the second best pigouvian tax this paper extends the mirrlees 1971 model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities using general utility structures and exploring both linear and non linear taxes it is demonstrated that the optimal second best tax on an externality generating good should not be corrected for the marginal cost of public funds since it equals one in the optimal tax system in the optimum distortions of income taxes are equal to marginal redistributional gains if the government does not have access to a non distortionary marginal source of finance the marginal cost of public funds can be either larger or smaller than one depending on subjective preferences for income redistribution the optimal second best corrective tax is then either higher or lower than the pigouvian level the findings in this paper generalize and amend prior results based on representative agent models shedding new light on the weak double dividend hypothesis and on the welfare gains of recycling revenue from environmental taxes

identifying the efficiency status in network dea abstract data envelopment analysis dea is commonly employed to evaluate the efficiency performance of a decision making unit dmu that transforms exogenous inputs into final outputs in such a black box dea approach details of an internal production process of the dmu are typically ignored and hence the locations of inefficiency are not adequately provided in view of this dea researchers have recently developed various network approaches by looking into the black box where the inputs that enter the box and the outputs that come out of it are only considered however most of these network approaches evaluate divisional efficiency by using an optimal solution of their respective optimization problem if such an optimal solution is used in the case when there are multiple optima then managerial guidance based on this solution alone may be inappropriate because more appropriate targets from the viewpoint of management may be ignored taking this fact into account therefore we propose a network approach for identifying the efficiency status of each dmu and its divisions this approach provides a practical computational procedure

100 percent reserve banking a critical review of green perspectives abstract 100 percent reserve banking c perb is an enduring proposal for monetary reform that has been taken up by some ecological economists this paper identifies three groups of green arguments in favor of c perb and offers some criticism first the proposal could serve to constrain new investments by the availability of savings thereby checking economic growth however this would strongly increase interest rate volatility second it could potentially elevate environmental considerations in decisions about resource allocation by increasing the role of the democratic state as an economic actor this line of argument faces problems that require further detailed exploration and historical perspective third a transition to c perb would allow debt levels to be drastically cut this is technically possible but politically a tall order whether the existing system of debt based bank money generates a significant growth imperative is unclear and the importance of other driving forces behind perennial economic growth in modern societies which c perb does not address remains an issue of contention in general the adoption of c perb presupposes a tremendous reconfiguration of power relations between states and finance capital

to value or not to value that is not the question abstract should we reject money when we value nature like most environmentalists ecological economists are increasingly divided on this question synthesizing political ecology with ecological economics we argue that this way of framing the question is limited we propose a reformulation of the question into when and how to value with money and under what conditions we recommend four criteria for a sound choice environmental improvement distributive justice and equality maintenance of plural value articulating institutions and confronting commodification under neo liberalism we call for due attention to the socio political context within which a valuation is placed and the political goals it serves the relevance of this framework is demonstrated by applying it to three practical cases pollution damages water pricing and payments for ecosystem services

capitalist diversity and de growth trajectories to steady state economies abstract growth critical scholarship has done much to both expose the environmentally unsustainable nature of the capitalist growth economies of the overdeveloped part of the world and to develop an alternative vision of a de growth transition leading to a steady state economy however this scholarship fails to adequately take into consideration that if planned de growth actually materialised it would do so in societies that differ considerably from one another and that this would have implications both for the transition processes and the nature of their outcomes in other words not enough importance is ascribed to capitalist diversity and the nature of institutional change in the growth critical literature against this background the purpose of the present article is to make the concrete utopia of de growth scholars and steady state economists more specific by utilising insights from scholarship on capitalist diversity and institutional change on the basis of a typology of different models of capitalism the article suggests that if de growth transitions took place they would take different forms and lead to a variety of types of steady state economies sses to illustrate this point three ideal typical sses are delineated

evaluating the environmental efficiency of a two stage system with undesired outputs by a dea approach an interest preference perspective abstract in this study we propose a new dea model to evaluate the environmental efficiency of a two stage system with undesired outputs the two stage system consists of two parts a production subsystem and a pollution treatment subsystem different choices for allocating resources to each subsystem represent different interest preferences of decision makers with the production subsystem corresponding to short term interests and the pollution treatment subsystem corresponding to long term interests based on a proposed new dea model three theorems are established to show the relationships between the interest preference parameter and the change of efficiency scores an empirical analysis was conducted using the data of 30 provinces and municipalities eight regions of china the empirical results show the effectiveness of the proposed model and the usefulness of the theorems for the real world data optimal efficiency rankings of the eight regions are provided and the efficiency rankings truly reflect the current environmental situations of these eight regions to examine the economic impacts and facilitate sustainable development we also analyze the shadow prices for undesired outputs corresponding implications of the empirical analysis are also discussed

economic democracy as an environmental measure abstract even though the conventional capitalist corporation is the globally dominant form of business organization it may not be the most environmentally friendly given the need for a sustainable steady state economic system some other form of business organization will likely be required that uses natural resource inputs more efficiently and is less growth oriented than the typical corporation an attractive alternative is the producer cooperative where employment is accompanied by a right to democratic participation in organizational governance and a share of surplus earnings a comparative theoretical analysis of cooperative and profit maximizing corporate behavior suggests that cooperatives will tend to use natural resource inputs more efficiently and will be less growth oriented than corporations the limited comparative empirical research that is available supports the greater input efficiency of cooperatives relative to corporations this same research suggests that in fully employed economies cooperatives will be less growth oriented than corporations although where unemployment is substantial the reverse is likely environmentally sustainable full employment is theoretically achievable through workweek reductions

industrial eco efficiency in china a provincial quantification using three stage data envelopment analysis abstract the coordinated development of industrialization and the ecological environment is vital to achieve ecological civilization in china integratively considering the economy energy and resources and environment this study aims to measure the industrial eco efficiency of 30 provinces autonomous regions and municipalities in china between 2005 and 2013 a three stage data envelopment analysis dea modeling approach is adopted to eliminate interference of the external environment and statistical noise with industrial eco efficiency measurement the results show that regional industrial eco efficiency in china is affected by the factors of the environmental regulation technological innovation level of economic development and industrial structure after eliminating the impacts of external environment and statistical noise china s national average industrial eco efficiency declines by 30 between 2005 and 2013 the industrial eco efficiency of the 30 provinces increases but at different rates of growth the variation of overall regional industrial eco efficiency is primarily caused by scale efficiency furthermore all the 30 provinces are classified into four groups to interpret the causes of variation and differences of regional industrial eco efficiency in general the management and technology level and the economy of scale of industries should be improved simultaneously even though specific opportunities for industrial eco efficiency improvement vary across provinces in china

progressive consumption tax minimum consumption and inequality abstract in this note we study the effects of a progressive consumption tax on wealth and consumption inequality in a model economy featuring minimum consumption we show that increasing the lower and upper bounds of the progressive tax rate reduces wealth and consumption inequality in the long run but is not sufficient the lower and upper bounds must not exceed the thresholds which are decreasing functions of minimum consumption the result is useful for empirical studies of the redistribution of wealth and consumption

decomposition weights and overall efficiency in two stage additive network dea abstract data envelopment analysis dea is a technique for performance evaluation of peer decision making units dmus the network dea models study the internal structures of dmus using two stage network structures as an example the current paper examines additive efficiency decomposition where the overall efficiency is defined as a weighted average of stage efficiencies and the weights are used to reflect relative importance of individual stages we show that weights may not affect the calculation of stage efficiency scores and that variation in the overall efficiency resulting from using different weights can be associated with constant stage efficiencies we demonstrate the need to isolate the impact of weights on the overall efficiency we propose to use a new overall efficiency index to address some pitfalls in weighted additive efficiency decomposition our findings are illustrated using two empirical data sets representing two types of two stage network structures

marx s reproduction schemes and the environment abstract ecological economists have argued that marx s reproduction schemes are self contained circular flows that downgrade the importance of natural conditions the present paper evaluates this criticism in light of both marx s methodology and his response to quesnay s tableau economique it is shown that marx follows quesnay in clearly distinguishing monetary circular flows from material throughput and that his schemes encapsulate the dependence of capitalist production on natural conditions as developed elsewhere in capital at the same time the purpose of marx s schemes is not to theorize environmental crises but to set out the basic exchanges necessary for capitalist reproduction as a material and social class process marx s analyses of capitalist environmental crises are developed at other points in capital

productivity and customer satisfaction in swedish pharmacies a dea network model this paper presents a data envelopment analysis dea network model that allows inclusion of customer satisfaction in efficiency and productivity measures the network consists of a production node and a consumption node and offers flexibility in modelling the production and consumption process where a firm specific allocation of input resources to production and customer oriented activities is allowed the proposed model is applied on a sample of swedish pharmacies with organizational objectives that necessitates a monitoring of efficiency and productivity as well as customer satisfaction estimation results from the network model and a direct productivity model without customer satisfaction are compared and indicate that the technical efficiency is lower under the network model the productivity results indicate productivity progress under both models albeit with a slower rate of change under the network model

dea like models for efficiency evaluations of specialized and interdependent units abstract the problem of evaluating the efficiency of a set of specialized and interdependent decision making subunits dmsus that make up a larger decision making unit dmu is considered the dmsus are interdependent in the sense that part of the output produced by each of them may be used as an input by the other ones they are also specialized hence non homogeneous as they may have not the same inputs and outputs for this problem some efficiency indexes are introduced and they are shown to satisfy some basic properties

overcoming accumulation is a capitalist steady state economy possible abstract this article critically reviews the case for a steady state zero growth economy posing the question whether such an economy can be stable and socially just given that in the current global economy lack of growth is synonymous with crisis the sse thesis is analysed within a framework of marxian political economy concluding that a stable and just sse is possible but not feasible within the social relations of capitalism using the marxian analysis of capital accumulation the article then considers whether the reforms proposed by ecological economists can form an effective countervailing force to the drive for accumulation the conclusion is that such reforms can be successful but only in so far as they are complemented and brought to their logical conclusion by a wider attempt to transcend the capitalist relations of production

best performing us mutual fund families from 1993 to 2008 evidence from a novel two stage dea model for efficiency decomposition when analyzing relative performance especially at the institutional level the traditional data envelopment analysis dea models do not recognize vastly different and important activities as separate functions and therefore cannot identify which function may be the main source of inefficiency we propose a novel two stage dea model that decomposes the overall efficiency of a decision making unit into two components and demonstrate its applicability by assessing the relative performance of 66 large mutual fund families in the us over the period 1993 2008 by decomposing the overall efficiency into operational management efficiency and portfolio management efficiency components we reveal the best performers the families that deteriorated in performance and those that improved in their performance over the sample period we also make frontier projections for poorly performing mutual fund families and highlight how the portfolio managers have managed their funds relative to the others during financial crisis periods

coal taxation reform in china and its distributional effects on residential consumers abstract there is an ongoing reform in coal taxation in china from a quantity based to a price based approach while the coal tax could play an important role in resource conservation and air pollution reduction its distributional effect is not well studied this paper investigates the distributional effect of china s coal taxes on households before and after the reform we find that about 30 percent of rural households and six percent of urban households are directly affected by the coal taxes and that the directly affected households tend to be poor we also find that provinces are affected differently by the coal taxes the provinces that are more affected tend to have lower household income by the suits index we find that both the quantity based and price based coal taxes are regressive for residential consumers in china and that the coal taxation reform had little effect on the regressivity of the coal tax by simulation we find that the regressivity of the coal tax could be reduced if the tax rate were set to be positively correlated with provincial household income

how to make a carbon tax reform progressive the role of subsistence consumption this letter analyzes the distributional effects of a carbon tax reform when households must consume carbon intensive goods above a subsistence level the reform is progressive if revenues are recycled as uniform lump sum transfers in other cases it is regressive

optimal control of externalities in the presence of income taxation a substantial literature examines second best environmental policy focusing particularly on how the pigouvian directive that marginal taxes should equal marginal external harms needs to be modified in light of the preexisting distortion due to labor income taxation additional literature is motivated by the possibility that distributive concerns should amend the internalization prescription it is demonstrated however that simple first best rules unmodified for labor supply distortion or distribution are correct in a natural basic formulation of the problem specifically setting all commodity taxes equal to marginal harms and subsidies equal to marginal benefits can generate a pareto improvement likewise a marginal reform in the direction of the first best can yield a pareto improvement qualifications and explanations for differences from previous work are also presented

technology appropriation in a de growing economy this article proposes a concept of technology appropriation as a means of ideological repurposing of technology in a de growing economy its economic and institutional foundations are set forth using an endogenous theory of economic development in the spirit of marx schumpeter and veblen technological and institutional change lead interdependently to the emergence of socio technical complexes which are subject to ideological appropriation these complexes are analyzed as actor networks from an ontological perspective and exemplified using special cases in the information and communication technologies icts the approach contributes to synthesizing critical political economy with actor network theory technology appropriation is elaborated as a means of repurposing existing technologies in terms of recombination with an emphasis on the strategy of habilitation this political economic strategy delivers new insights for a solidary mode of economic reproduction in a low carbon de growing economy

co2 taxes equity and the double dividend macroeconomic model simulations for austria abstract this paper investigates the impacts of co2 tax schemes on co2 emissions equity and macroeconomic indicators in austria with the macroeconomic model dynk aut our scenarios focus on non ets co2 emissions and comprise different tax rates and revenue recycling options lower labor taxes lower vat and lump sum payments the short term comparative scenario analysis indicates that co2 taxes without recycling lead to significant co2 emission reductions at moderate economic costs equity impacts on households depend on the indicator used but can be regressive without recycling most recycling schemes can achieve a double dividend i e emission reductions and increases in gdp lump sum payments are less efficient than reducing the vat or labor taxes equity impacts are progressive with lump sum payments rather proportional with lower vat and regressive with lower labor taxes a combination of recycling schemes and or a restriction of lump sum payments to lower income households can minimize the trade off between equity and efficiency our simulations suggest that well designed co2 tax schemes could be a crucial and socially acceptable element within a comprehensive policy package to achieve ghg emission targets for non ets sectors in austria

the economics of degrowth economic degrowth is ecologically desirable and possibly inevitable but under what conditions can it become socially sustainable how can we have full employment and economic stability without growth what will happen to public spending and to public debt how would production be organised in a degrowing economy and under what plausible socio political conditions could such grand changes happen standard economic theories and models ignore these questions for them economic growth is an axiomatic necessity this article reviews recent contributions in the economics of degrowth and identifies research avenues for ecological economists

externalities and optimal taxation this paper reexamines the optimal tax design problem income and commodities in the presence of externalities the nature of the second best and the choice of the tax instruments are motivated by the informational structure in the economy the main results are i environmental levies linear or nonlinear differ in formula from pigouvian taxes by the expressions for the optimal tax on private goods ii externalities do not affect commodity tax formulas linear and nonlinear for private goods iii externalities do not affect the income tax structure if commodity taxes are nonlinear and affect it if commodity taxes are linear and iv a general income tax plus strictly pigouvian taxes are sufficient for efficient taxation if individuals of different types have identical marginal rates of substitution at any given consumption bundle

a new carbon tax in portugal a missed opportunity to achieve the triple dividend in 2014 the portuguese government appointed a commission for environmental tax reform that formulated a carbon tax proposal designed to achieve three dividends to help portugal meet the european union s target for emissions reductions by 2030 to boost long term employment and gdp above their pre carbon tax levels and to strengthen public finances by lowering public indebtedness a key feature of this proposal was a judicious set of mixed strategies to recycle all carbon tax revenues back into the economy in this note we show how the carbon tax that the portuguese parliament eventually approved deviated from such guidelines and ultimately failed to achieve the triple dividend we argue that authorities need to quickly amend the existing legislation to avoid this misguided attempt turning into a missed opportunity to improve environmental macroeconomic and fiscal outcomes

productivity and intermediate products a frontier approach abstract in recent years it has become popular to measure productivity using non parametric approaches however this has been done while ignoring intermediate products here we develop a non parametric productivity measure that explicitly incorporates such products

galtung meets daly a framework for addressing inequity in ecological economics abstract since world war ii economic growth has been the leading policy goal in efforts to eradicate poverty there is strong evidence that this strategy has gone hand in hand with increasing inequity and environmental degradation we need concepts that will help us understand the inadequacies of the current economic system we propose drawing from the ideas of sociologist johan galtung on social power structures and those of economist herman daly on the physical features of the economy a fusion of these perspectives creates a novel framework for analysis and a basis to formulate alternatives to the current growth strategy

distributional impacts of carbon pricing a general equilibrium approach with micro data for households article i nfo many policies to limit greenhouse gas emissions have at their core efforts to put a price on carbon emissions carbon pricing impacts households both by raising the cost of carbon intensive products and by changing factor prices a complete analysis requires taking both effects into account the impact of carbon pricing is determined by heterogeneity in household spending patterns across income groups as well as heterogeneity in factor income patterns across income groups it is also affected by precise formulation of the policy how is the revenue from carbon pricing distributed as well as the treatment of other government policies e g the treatment of transfer payments what is often neglected in analyses of policy is the heterogeneity of impacts across households even within income or regional groups in this paper we incorporate 15 588 households from the u s consumer and expenditure survey data as individual agents in a comparative static general equilibrium framework these households are represented within the mit usrep model a detailed general equilibrium model of the u s economy in particular we categorize households by full household income factor income as well as transfer income and apply various measures of lifetime income to distinguish households that are temporarily low income e g retired households drawing down their financial assets from permanently low income households we also provide detailed within group distributional measures of burden impacts from various policy scenarios

comprehensive effectiveness assessment of renewable energy generation policy a partial equilibrium analysis in china abstract in order to stimulate renewable energy and control carbon dioxide emissions the chinese government has already introduced lots of renewable energy generation policies under this background it is of great significant to figure out the economic environmental and social effectiveness of these polices firstly this paper systematically studied the framework and content of renewable energy generation policies secondly this paper built a basic partial equilibrium model to calculate the equilibrium state of electricity market and carbon emissions on this base the effectiveness of seven renewable energy generation policies was analyzed by introducing policies into the basic model and comparing relevant indicators in different policy scenarios with that in basic scenario further an empirical analysis was made to estimate the actual benefits of these policies in china this paper proposed an analysis method for evaluating the mechanism effectiveness and efficiency of renewable energy generation policies all the results and discussions in this paper can provide specific suggestions for chinese government to shape a blueprint for implementing different kinds of policies

what factors drive inequalities in carbon tax incidence decomposing socioeconomic inequalities in carbon tax incidence in ireland abstract carbon taxes increase the cost of necessary household energy expenditures in many developed countries carbon taxes are regressive as they comprise a greater proportion of a poorer household s income certain socioeconomic groups are more negatively affected by these impacts than others while inequality of incidence by income group has received great attention in the literature a gap exists to quantify the inequality associated with socioeconomic characteristics this information is policy relevant as it may inform the most effective means to offset negative welfare impacts through changes to taxes and or social transfers this paper provides this contribution first the inequality of carbon tax incidence across the income spectrum is quantified using the concentration index methodology a subsequent multivariate decomposition quantifies the contribution each socioeconomic factor makes towards this inequality of incidence this is carried out for electricity motor fuel and all other home fuels to elicit variation of socioeconomic incidence by source while income contributes a great deal towards inequality of incidence for other home fuels other socioeconomic characteristics are the primary determinants of electricity and motor fuel related carbon tax incidence the relative importance of each characteristic in determining regressive impacts is quantified and this varies by carbon tax source

deriving the dea frontier for two stage processes data envelopment analysis dea is a method for measuring the efficiency of peer decision making units dmus recently dea has been extended to examine the efficiency of two stage processes where all the outputs from the first stage are intermediate measures that make up the inputs to the second stage the resulting two stage dea model provides not only an overall efficiency score for the entire process but as well yields an efficiency score for each of the individual stages due to the existence of intermediate measures the usual procedure of adjusting the inputs or outputs by the efficiency scores as in the standard dea approach does not necessarily yield a frontier projection the current paper develops an approach for determining the frontier points for inefficient dmus within the framework of two stage dea

optimal control of externalities in the presence of income taxation optimal control of externalities a substantial literature examines second best environmental policy focusing particularly on how the pigouvian directive that marginal taxes should equal marginal external harms needs to be modified in light of the preexisting distortion due to labor income taxation additional literature is motivated by the possibility that distributive concerns should amend the internalization prescription it is demonstrated however that simple first best rules unmodified for labor supply distortion or distribution are correct in a natural basic formulation of the problem specifically setting all commodity taxes equal to marginal harms and subsidies equal to marginal benefits can generate a pareto improvement likewise a marginal reform in the direction of the first best can yield a pareto improvement for other reforms a simple efficiency test characterizing when a pareto improvement is possible is offered qualifications and explanations for the substantial departure from results in previous work are also elaborated

assessment of china transit and economic efficiencies in a modified value chains dea model abstract this study incorporates the concepts of undesirable intermediate intermediate input uncontrollable input and undesirable output to the value chains model chen and zhu 2004 thereby creating a modified value chains model to compute transit and economic efficiencies in 30 regions of china the modified value chains model forms a more general formulation to the value added chains in the utilization of the above concepts it also provides an optimal intermediate measure which differs from the independent two stage measure empirical evaluations indicate that large scale transit development in china s coastal area does not necessarily represent higher transit efficiency because in the coastal area there is a lack of significant positive relationships between transit and economic efficiency high economic efficiency does not contribute to greater transit efficiency the finding also suggests that by simultaneously decreasing the quantity in passenger and freight transport transit and economic efficiencies have greatly improved in most regions of china

ecological monetary economics a post keynesian critique the monetary analysis of some ecological economists currently appears to be mostly articulated around the following core a stationary economy and a fortiori a degrowth economy is incompatible with a system in which money is created as interest bearing debt to question the relevance of the debt money positive interest rate output growth nexus this paper adopts a critical stance towards the currently emerging ecological monetary economics from the standpoint of another strand of heterodox economics the post keynesian approach in its current state ecological monetary economics is at odds with post keynesian economics in its analysis of the money growth relationship this will be shown using the theory of endogenous money and a simple cambridgian kaleckian model where debt money and a positive interest rate are compatible with a full stationary economy

two paradoxes with one stone a critical reading of ecological modernization abstract the current contribution aims at critically reviewing state initiatives in the frame of ecological modernization under the lenses of the labor theory of value further the article addresses two phenomena related to ecological modernization that have received much attention namely the porter hypothesis and the jevons paradox state led environmental regulation in terms of environmental legislation as well as initiatives to promote green technology can be understood as a twofold attempt which ultimately leads to re defining socially necessary labor time first state intervention would wish to remove surplus profit from polluting or resource depleting capitals through legislation which would tend to increase socially necessary labor time in the branch of production under reference state policy might then attempt to propel the adoption of green technology which would tend to decrease socially necessary labor time in the sectors targeted through state initiatives competition among rival capitals would be re aligned so as to allow for conditions of production to be renewed the porter hypothesis can be approached as a strategy followed by individual capitals to gain an early mover advantage while the jevons paradox can be seen as the result of an imitation process when rival capitals take up technological modifications launched by innovators

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

can carbon taxes be progressive abstract most studies have assessed the distributional impact of carbon taxes through their effects on commodity prices alone while ignoring their impact on individual welfare brought about by changes in factor prices yet the remunerations of capital and labor are not affected by these taxes similarly and their shares in earned incomes are not uniform across households this paper provides a comprehensive analysis of the incidence of carbon taxes on inequality by considering simultaneously the commodity and the income channels we propose a decomposition of the change in individual welfare metrics then we develop a general equilibrium model to assess the impact of carbon taxes on factor and commodity prices and subsequently their distributional impact on households using the lorenz and concentration curves and the gini index our results suggest that changes in factor prices and changes in commodity prices especially those of energy commodities have opposing effects on inequality carbon taxes tend to reduce inequality through the changes in factor prices and tend to increase inequality through the changes in commodity prices hence we find a non monotonic u shaped relationship between carbon taxes and inequality our results suggest that the traditional approach of assessing the impact of carbon taxes on inequality through changes in commodity prices alone may be misleading the findings cast light on the desirability of using both channels in the assessment of carbon taxes on inequality

economic instruments for environmental regulation our knowledge about economic incentive approaches to pollution control has grown rapidly in the two decades in which they have received serious analytical attention not only have the theoretical models become more focused and the empirical work more detailed but we have now had over a decade of experience with emissions trading in the u s and emission charges in europe as the world community becomes increasingly conscious of both the need to tighten environmental controls and the local economic perils associated with tighter controls in a highly competitive global marketplace it seems a propitious time to stand back and to organize what we have learned about this practical and promising approach to pollution control that may be especially relevant to current circumstances this paper draws upon economic theory empirical studies and actual experience with implementation to provide a brief overview of some of the major lessons we have learned about two economic incentive approaches emissions tradi copyright 1990 by oxford university press

development and application of the hicks moorsteen productivity index for the total factor productivity assessment of wastewater treatment plants abstract the assessment of the productivity change in wastewater treatment plants is essential to improve performance and reduce operational costs several indices are available to compute unit productivity however some assessments are more reliable than others in the absence of price data the malmquist productivity index is the most commonly applied but it does not maintain total factor productivity properties under variable returns to scale technology hence malmquist productivity index is not a suitable index to compute total factor productivity change in wastewater treatment plants the present study served to overcome such limitations by calculating for the first time total factor productivity changes in a sample of 204 spanish wastewater treatment plants using the hicks moorsteen productivity index it is a multiplicatively complete index which can be decomposed as several sub indices representing technical and efficiency changes therefore this study also investigated the drivers of total factor productivity change in wastewater treatment plants results showed a 5 4 total factor productivity decline per year from 2003 to 2008 in the plants analysed the primary driver in the reduction was efficiency change alternatively technical change improved during the five years of study the results of this study provide support for policymakers and managers in decision making processes and contribute to the improvement of technical and economic wastewater treatment plants performance in addition it is evidenced that wastewater treatment plants current dependence on external energy sources should be reduced to improve productivity and reduce costs to citizens who pay for wastewater treatment services

the economic and financial dimensions of degrowth abstract we respond to the call for future research on degrowth and specifically analyze the implications of economic degrowth on the monetary and financial system we argue that any early indications of degrowth would cause the stock market to crash which would trigger further deleveraging contagion and a deflation as a result the economy would implode which would eventually allow for a new rapid growth cycle given the likely extraordinary fiscal and monetary policy response during the implosion thus in our view degrowth as an explicit strategy option is economically unsustainable and unfeasible as a limitation our analysis centers on the examples of unplanned crisis leading to an economic implosion which imperfectly represent the idea of planned voluntary degrowth

from regressive pollution taxes to progressive environmental tax reforms european countries have increased their use of environmental tax instruments by designing new tax bases but many countries face opposition from public opinion for fear of the distributive consequences of these environmental tax reforms this paper sheds light on the distributive consequences of environmental tax policies when households are heterogeneous the objective is to assess whether an environmental tax reform could be pareto improving when the revenue of the pollution tax is recycled by a change in labor tax properties we show that whatever the degree of regressivity of the environmental tax alone it is possible to design a recycling mechanism that renders the tax reform more pareto efficient by simultaneously decreasing the wage tax and increasing its progressivity

redistribution and pollution taxes with non linear engel curves abstract this paper analyses optimal corrective taxation and optimal income redistribution the pigouvian pollution tax is higher if pollution damages disproportionally hurt the poor due to equity weighting of pollution damages moreover under general utility functions optimal pollution taxes should be set below the pigouvian tax if the poor spend a disproportionate fraction of their income on polluting goods however if engel curves are linear optimal pollution taxes should follow the first best rule for the pigouvian corrective tax even if the government wants to redistribute income and the poor spend a disproportional part of their income on polluting goods the often used quasi linear ces and stone geary utility functions all have linear engel curves if engel curves are linear and if pollution taxes are not optimised pareto improving green tax reforms exist that move the pollution tax closer to the pigouvian tax simulations demonstrate that optimal corrective taxes should be pigouvian if the demand for polluting goods is derived from a les demand system but deviate from the pigouvian taxes if demand for polluting goods demand is derived from a piglog demand system

the prerequisites for a degrowth paradigm shift insights from critical political economy abstract what would it take for a degrowth paradigm shift to take place drawing on contemporary critical political economy scholarship this article identifies four prerequisites for socio economic paradigm shifts deep crisis an alternative political project a comprehensive coalition of social forces promoting the project in political struggles and broad based consent it is argued that on the one hand there is much to suggest that current crises cannot be resolved under existing institutional frameworks and that degrowth is a political project that provides solutions to some of the key problems currently facing humanity on the other hand the prospects for a degrowth paradigm shift remain bleak unlike political projects that became hegemonic in the past degrowth has neither support from a comprehensive coalition of social forces nor any consent to its agenda among the broader population
