an environmental performance index for products reflecting damage costs abstract several studies have demonstrated how to use dea data envelopment analysis based techniques to estimate environmental performance indices none of these studies however are taking information on the environmental damage costs of the pressure types considered into account this study is bridging a gap between environmental indices founded in physical pressures and damage costs founded in welfare economics the aim of the paper is twofold first to demonstrate how to implement the information on environmental damage costs within a dea based environmental performance index and second to estimate these indices at product level by using danish input output data and environmental data from 1997

the price of pollution a dual approach to valuing so2 allowances under the 1990 clean air act amendments a market based scheme to reduce u s sulfur dioxide emissions takes effect in 1995 indications are that participation in the market will be light and allowance prices will be lower than was once expected using an output distance function approach for wisconsin coal burning utility plants we estimate the shadow price of so2abatement which should approximate the allowance price the estimated average shadow price is above the prices at which the few observed allowance trades have occurred wisconsin s stringent state so2legislation may explain a portion of this divergence

input orientated data envelopment analysis framework for measuring and decomposing economic environmental and ecological efficiency an application to oecd agriculture this paper presents an input orientated data envelopment analysis dea framework which allows the measurement and decomposition of economic environmental and ecological efficiency levels in agricultural production across different countries economic environmental and ecological optimisations search for optimal input combinations that minimise total costs total amount of nutrients and total amount of cumulative exergy contained in inputs respectively the application of the framework to an agricultural dataset of 30 oecd countries revealed that i there was significant scope to make their agricultural production systems more environmentally and ecologically sustainable ii the improvement in the environmental and ecological sustainability could be achieved by being more technically efficient and even more significantly by changing the input combinations iii the rankings of sustainability varied significantly across oecd countries within frontier based environmental and ecological efficiency measures and between frontier based measures and indicators

environmental efficiency measurement and the materials balance condition reconsidered abstract this note takes up a shortcoming of coelli et al s 2007 popular environmental efficiency measure and its extension to economic environmental trade off analysis see van meensel et al 2010 namely that they do not reward emission reductions by pollution control a new environmental efficiency measure that overcomes this issue and similar to coelli et al s efficiency measure is in line with the materials balance principle is proposed and further decomposed into technical environmental efficiency and material and nonmaterial allocative environmental efficiencies the new efficiency measure collapses into coelli et al s efficiency measure if none of the considered decision making units control pollutants a numerical example using data envelopment analysis is provided to further explore the properties of the new efficiency measure

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

a derivation of the marginal abatement cost curve abstract the relationship between a firm s technology and its marginal abatement cost mac curve is explored even under the simplest specifications the mac curve will be kinked at some point except under a special assumption which in reality could easily be violated the nondifferentiability implies that the choice of instrument under uncertainty may depend on the targeted level of emissions reduction also stability conditions for dynamic tax mechanisms may be violated in the neighborhood of the kink point a policy implication is that in some cases output restrictions are as efficient as emissions restrictions in contrast to previous results

political risk and export promotion evidence from germany political risk represents an important hidden transaction cost that reduces international trade this paper investigates the claim that german public export credit guarantees hermes guarantees mitigate this friction to trade flows and hence promote exports we employ an empirical trade gravity model where we explicitly control for political risk in the importing country in order to evaluate the effect of export guarantees the idea behind export promotion through public export credit agencies ecas is that the private market is unable to provide adequate insurance for all risks associated with exports as a consequence firms export activities are limited in the absence of insurance provision using a novel data set on guarantees we estimate the effect of guarantees in a static and dynamic panel model we find a statistically and economically significant positive effect of public export guarantees on exports which indicates that export promotion is indeed effective furthermore political risk turns out to be a robust determinant of exports and hence should be taken into account in any empirical model of trade

sufficiency or efficiency to achieve lower resource consumption and emissions the role of the rebound effect a frequent criticism of eco efficiency strategies is that an increase in efficiency can be offset by the rebound effect sufficiency is discussed as a new strategy involving self imposed restriction of consumption but can also be subject to the rebound effect we show that the range of possible secondary effects of efficiency and sufficiency strategies goes beyond the rebound effect the rebound effect can indeed also be linked to eco sufficiency strategies but there are further secondary effects of both eco efficiency and eco sufficiency strategies such as double dividend effects we develop an eco efficiency sufficiency matrix to logically order eco efficiency and sufficiency measures to attain lower resource consumption and emissions

comparing frontier methods for economic environmental trade off analysis abstract this paper uses a mechanistic frontier approach as a reference to evaluate the ability of conventional parametric sfa and non parametric dea frontier approaches for analyzing economic environmental trade offs conventional frontier approaches are environmentally adjusted through incorporating the materials balance principle the analysis is worked out for the flemish pig finishing case which is both representative and didactic results show that on average sfa and dea yield adequate economic environmental trade offs both methods are good estimators for technical efficiency cost allocative and environmental allocative efficiency scores are less robust due to the well known methodological advantages and disadvantages of sfa and dea for particular firms sfa dea and the mechanistic approach may yield different economic environmental trade offs one has therefore to be careful when using conventional frontier approaches for firm specific decision support the mechanistic approach allows for optimizing performances per average present finisher which is the production unit in pig finishing conventional frontier methods do not allow for this optimization since the number of average present finishers varies along the production functions since the mechanistic production function is based on underlying growth feed uptake and mortality functions additional firm specific indicators can also be calculated at each point of the production function

non linear production abatement pollution and materials balance reconsidered abstract in the environmental economics literature the standard approach of modeling non linear production and abatement processes is to treat waste emissions simply as another factor of production cropper and oates j econ lit 30 1992 675 740 that approach does not map the materials flow involved completely and hides moreover the exact links between production residuals generation and abatement this paper shows that production functions with emissions treated as inputs can be reconstructed as a subsystem of a comprehensive production cum abatement technology that is in line with the materials balance principle in a simple economy with full regard of the materials flow it also explores the consequences for allocative efficiency and efficiency restoring taxation of multiple and interdependent residuals generated in the transformation processes of production abatement and consumption finally the paper demonstrates that efficiency may require setting the emissions tax rate above or below conventionally defined marginal abatement cost if the residual subject to abatement is not the only residual causing pollution

the if how and where of assessing sustainable resource use in today s economies those who sustain the burden of resource use those using resources and those providing resources are not necessarily identical with this separation come three fundamental but interrelated decision making perspectives on the sustainability assessment of resource use these three perspectives correspond to the three assessment questions if how and where resources should be used most sustainability assessment approaches do not make their underlying assessment perspectives explicit the goal of this paper is to provide structure and organisation to existing approaches this structuring suggests that any discussion on the appropriateness and validity of different assessment approaches and their results must take into account the underlying assessment perspective the three questions if how and where resources should be used correspond to the requirements of a sustainable resource use while existing assessments do address the three questions in isolation it is all the more important that the limitations and implications of focusing on a single perspective are spelled out as the main contribution the paper distinguishes the rationale of each assessment perspective and develops on their interlinkages and thus provides the context and structure for a more informed and fruitful debate on the assessment of sustainable resource use

credit support for export robust evidence from the czech republic the topic of this paper is quite a novel one it is one of few empirical academic papers dealing with export credit moreover it is the first analysis of this kind which focuses on transition economies the paper deals with export credit promotion in the czech republic the development and structure of czech trade and export support is presented first followed by an econometric analysis of the gravity model of czech republic trade a panel of 160 countries in 1996 2008 is analysed and two gravity models of exports for the czech republic are estimated the static model by fixed effects lsdv estimator and the dynamic model by system gmm due to ambiguous conclusions we assume that the behaviour of our explanatory variables is not uniform and our data set behaves as a mixture of countries with heterogeneous behaviour this means that traditional techniques of estimation which include all observations into one model do not give significant results thus we use robust techniques of estimation that solve the problem of heterogeneous patterns in data sets out of several possibilities we use the least trimmed squares estimator lts with a leverage point we show that guarantees are a significant factor that influences positively the volume of exports in the czech republic moreover there exist more variables that affect the size of exports in the czech republic market forces described by gdp distance political risk or gross fix capital formation are significant in our econometric model we find that higher gdp shorter distance or lower political risk have a positive impact on czech exports

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

economic versus environmental improvement potentials of danish pig farms this article demonstrates how economic and environmental improvement potentials of danish pig farms can be estimated using data envelopment analysis dea to avoid some of the problems associated with the definition of undesirable outputs environmental variables are included as nutrients applied with manure and nutrients removed with the crops these environmental variables are combined with a series of economic variables including the costs of fertilizer furthermore subvector efficiency and a two step analysis are used in order to consider economic and environmental technical efficiency separately the empirical results show considerable improvement potentials especially on the environmental variables sensitivity studies validate that these results are robust to possible uncertainties in the measurement of the environmental variables

the concept of joint production and ecological economics joint production is suggested as one of the conceptual foundations of ecological economics the notion of joint production springs immediately from the application of thermodynamics and has a long history in economic analysis considerations of joint production give rise to philosophical concerns relating to responsibility and knowledge the concept of joint production is easily comprehensible and is also constitutive and supportive of a range of concepts current in ecological economic thought 2001 elsevier science b v all rights reserved

on the intergenerational allocation of natural resources it is known hartwick and others that under standard assumptions a society that invests in reproducible capital the competitive rents on its current extraction of exhaustible resources will enjoy a consumption stream constant in time it is shown here that this result can be interpreted as saying that an appropriately defined stock of capital including the initial endowment of resources is being maintained intact and that consumption can be interpreted as the interest on that patrimony this seems like a useful rule of thumb for policy

ranking farms with a composite indicator of sustainability the assessment of sustainability at farm level has been growing in popularity over the last few years this article contributes to this line of research by building up composite indicators for different facets social economic environmental and global of farm sustainability using a methodological approach that combines data envelopment analysis dea and multicriteria decision making mcdm methods and assigns common weights to each individual sustainability indicator this approach is applied to a database of 163 farms located in the campos county a region belonging to the dry lands of the spanish northern plateau using 12 individual indicators of sustainability our findings show that both economic and environmental composite sustainability indicators are positively correlated but that this is not the case for the social indicator we also check the influence of a set of variables on farm sustainability using bootstrapping statistical techniques and showing that increasing farm size membership in agricultural cooperatives and farmers medium and upper agricultural specific technical education all exert a significant positive influence on sustainability these results provide clues for policy makers that intend to design sustainability increasing structural agricultural policies

the environmental performance of dutch government bond funds we investigate the implications of using different indicators to assess the sustainability performance of investment funds in particular we look into the environmental performance of dutch government bond funds we find that it does matter a lot which particular indicator is used this suggests that funds should be very transparent and straightforward about their non financial performance we argue that basically they have three options first the industry comes up with a benchmark against which the responsibility of their investments is measured and reported by all funds second the funds make very clear and transparent which particular aspects of sustainability they specifically target and how they keep score third the dashboard approach where the funds report their performance on a well defined set of indicators

insecurity and the pattern of trade an empirical investigation corruption and imperfect contract enforcement dramatically reduce international trade this paper estimates the reduction using a structural model of import demand in which insecurity acts as a hidden tax on trade we find that inadequate institutions constrain trade as much as tariffs do we also find that omission of indices of institutional quality biases the estimates of typical gravity models obscuring a negative relationship between per capita income and the share of total expenditure devoted to traded goods finally we argue that cross country variation in the effectiveness of institutions and the consequent variation in the prices of traded goods offer a simple explanation for the stylized fact that high income capital abundant countries trade disproportionately with each other

eco efficiency in micro enterprises and small firms a case study in the automotive services sector abstract a significant number of small and micro enterprises worldwide make important contributions to global the economy however research studies that deal with this kind of enterprise especially regarding their environmental issues are limited this paper aims to demonstrate the viability of eco efficient practices among small firms and micro enterprises as a competitive advantage tool eco efficient practices were applied in a micro sized auto parts and electrical automotive services enterprise in brazil the procedures were applied based on the brazilian business council for sustainable development and the brazilian support for micro and small enterprises eco efficiency model the outcomes were evaluated and then measured again three years later to provide more consistent results the approach was carried out using qualitative action research followed by a statistical analysis of variance anova and an f test to compare the averages of the entire studied period together with a post hoc tukey statistical test to identify which averages among the studied years were driving significant differences levene s test was also performed to verify the homogeneity of the variance between all of the studied years in order to corroborate the analysis as important findings from this approach the micro sized enterprise attained better financial environmental and social performance and has purchased new financial incomings an important aspect was the engagement of the staff and owner during the implementation and evaluation of the new eco efficient practices eco efficient practices had positive and enduring results as verified by statistical analysis among the five studied years this provides evidence that eco efficient practices could provide low cost benefit for both environmental and small and micro enterprises

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

environmental emissions and production economics implications of the materials balance in modeling emissions the literature has usually specified an explicit emission function or treated emissions as a production input we examine the validity of these approaches taking into account the materials balance principle we show that a technology can equivalently be described by i a production function with material and nonmaterial inputs and bounded marginal product of the material input ii a well behaved production function with emissions as an input and iii a well behaved emission function if the materials balance is accounted for as an additional condition we offer a forma derivation of common but not rigorously established modeling approaches

green accounting and economic policy abstract through the lens of conventional national accounting resource depletion and natural environment degradation often appear misleadingly as desirable economic growth the old system of national accounts sna has been revised and a set of environmental satellite accounts proposed certain weaknesses however pervade the new proposals the conventional measurements remain largely unaltered and the satellite accounts are of unclear purpose and unnecessarily complex as proposed they rely on the valuation of environmental stocks while the economically more important flow accounts to their detriment are to be derived indirectly from changes in stock values the sna the paper stresses is primarily an economic framework incapable of capturing all environmental change and the national accounts are far more useful economically than environmentally greening the accounts would be optional for most affluent countries whose overriding environmental concern is pollution this can be addressed directly through taxation and regulation pollution information in satellite accounts can indeed be valuable but revised and fully integrated resource accounting is a priority concern for those developing countries that are running down natural resources and for which conventional accounting distorts macroeconomic measurement analysis and policy the paper argues that green accounting can only ensure income sometimes called weak sustainability which should be considered as a step leading ultimately to an ecological or stronger sustainability

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

it pays to be green a premature conclusion it has been claimed that good environmental performance can improve firms economic performance however because of e g data limitations the methods applied in most previous quantitative empirical studies on effects of environmental performance on economic performance of firms suffer from several shortcomings we discuss these shortcomings and conclude that previously applied methods are unsatisfactory as support for a conclusion that it pays for firms to be green then we illustrate the consequences of these shortcomings by performing several regression analyses of the effect of environmental performance on economic performance using a panel data set of norwegian plants a pooled regression where observable firm characteristics like e g size or industry are controlled for confirms a positive effect of environmental performance on economic performance however the estimated positive effect could be due to omitted unobserved variables like management or technology when the regression model controls for unobserved plant heterogeneity the effect is generally no longer statistically significant hence although greener plants tend to perform economically better the analysis provides little support for the claim that it is because they are greener these empirical findings further indicate that a conclusion that it pays to be green is premature

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

the distributional impacts of indonesia s financial crisis on household welfare a rapid response methodology analyzing the distributional impacts of economic crises is an ever more pressing need if policymakers are to intervene to help those most adversely affected they need to identify those who have been hurt most and estimate the magnitude of the harm they have suffered they must also respond in a timely manner this article develops a simple methodology for measuring these effects and applies it to analyze the impact of the indonesian economic crisis on household welfare using only pre crisis household information it estimates the compensating variation for indonesian households following the 1997 asian currency crisis and then explores the results with flexible nonparametric methods it finds that virtually every household was severely affected although the urban poor fared the worst the ability of poor rural households to produce food mitigated the worst consequences of the high inflation the distributional consequences are the same whether or not households are permitted to substitute toward relatively cheaper goods households with young children may have suffered disproportionately large adverse effects

in kind finance a theory of trade credit it is typically less profitable for an opportunistic borrower to divert inputs than to divert cash therefore suppliers may lend more liberally than banks this simple argument is at the core of our contract theoretic model of trade credit in competitive markets the model implies that trade credit and bank credit can be either complements or substitutes among other things the model explains why trade credit has short maturity why trade credit is more prevalent in less developed credit markets and why accounts payable of large unrated firms are more countercyclical than those of small firms

lasting impacts of indonesia s financial crisis abstract we study the poverty impacts over time and space of indonesia s severe economy wide crisis of 1998 using 10 large national surveys spanning 1993 2002 on allowing for shifts in relative prices stemming from the crisis we find a sharp but geographically uneven increase in the poverty rate in 1998 reflecting both the unevenness in the extent of the economic contraction and the differing initial conditions at the local level our counterfactual analyses indicate geographically diverse recovery rates 4 years later proportionate impacts on the poverty rate in both 1998 and 2002 were greater in initially better off and less unequal districts in the aggregate a large share possibly half of the poverty count in 2002 is attributed to the 1998 crisis

cash crop choice and income dynamics in rural areas evidence for post crisis indonesia in this article we investigate the factors affecting levels and growth of incomes in rural indonesia following the crisis of 1997 1998 in particular we investigate the relative roles of nonfarm incomes and productivity improvements achieved via changes in crops versus improvements on the same crops on income dynamics framing the article in the context of an optimal labor allocation model relying on unique household panel data from central sulawesi and using advanced panel econometric methods we find that local innovations related to the adoption and intensification of new cash crop varieties more specifically the shift from coffee to cocoa production can explain a substantial part of the observed post crisis developments causal estimates of the effect of growing cocoa suggest that households were on average able to achieve about 14 higher income levels during the post crisis period compared to the planting of other crops most notably coffee also our results demonstrate the importance of engagement in nonfarm activities for household income growth comparative analyses using a nationally representative survey suggest that similar processes are at play in other parts of indonesia

export credit guarantees and export performance an empirical analysis for germany recent literature finds that exporters are particularly vulnerable to financial market frictions as a consequence exports may be lower than their efficient levels for this reason many countries support exporters by underwriting export credit guarantees the empirical evidence on the effects of those policies is however very limited in this paper we use sectoral data on export credit guarantees issued by the german government we investigate whether those guarantees indeed do increase exports and whether they remedy the export restricting effect of credit market imperfections both on the sectoral and on the export market levels exploiting the sectoral structure of a rich three way panel data set of german exports we control for unobserved heterogeneity on the country year sector year and country sector dimensions we document a robust export increasing effect of guarantees there is some evidence that the effect is larger for export markets with poor financial institutions and in sectors that rely more on external finance

rethinking productivity why has productivity focussed on labour instead of natural resources the contribution of natural resources and ecosystems to economic processes still remains under assessed by market evaluation and productivity analysis following the historical lines of the classical productivity debate ranging from the french physiocrats to early neoclassical growth theories the productivity concept underwent a gradual transformation from its previous understanding based on natural resources and other environmental factors to its contemporary narrow notion this paper claims that the course of the classical debate has shaped the scope of predominant contemporary analysis except for some very recent findings multifactor productivity largely focusses on a two factor model material flow analysis mfa provides a useful step for widening the measurement and notion of productivity

capital theory and the measurement of sustainable development an indicator of weak sustainability the measurement of sustainable development is not without considerable difficulties yet this should not detract from the positive advances that can be made in this direction in this paper we present one form that a weak sustainability indicator can take derived from a simple but intuitive savings rule it incorporates the idea that the level of overall capital stock should be non decreasing although subject to qualification at this stage some interesting results emerge from the application of the rule to 18 countries

measuring farm sustainability and explaining differences in sustainable efficiency abstract a major objective of european agricultural policy is to have a sustainable and efficient farming sector that is applying environmentally friendly production methods policy makers aim to combine a strong economic performance and a sustainable use of natural resources therefore it is important to measure and to assess farm sustainability for a large dataset of flemish dairy farms a valuation method that is based on the concept of opportunity costs is used to calculate and analyze differences among the sample farms with respect to the creation of sustainable value but more important than measuring the creation of sustainable value is to analyze differences in sustainable efficiency therefore sustainable efficiency measures are calculated and differences in sustainable efficiency are explained using panel data an effect model captures the determinants of sustainable efficiency of the studied farms the empirical model shows that in general larger farms have a higher sustainable efficiency also farmer s age and dependency on support payments proved to be determining characteristics for observed differences in sustainable efficiency

does the us exim bank really promote us exports this paper investigates the impact of us export import bank exim on us exports particularly in the wake of international competition from foreign national export credit agencies ecas we employ a gravity framework on a country industry year level panel data set that matches exim authorisations with us bilateral exports our results depict the general ineffectiveness of the bank in promoting exports within and across industries some heterogeneities behind the general finding are also uncovered industries other than aerospace parts and products are more likely to benefit from exim authorisations and exim authorisations to larger businesses seem to be more effective in encouraging exports furthermore we find no evidence that exim encourages us exports by offsetting foreign eca competition these results are neither affected by competing countries membership to the oecd arrangement nor by the size of american firms that received exim support our results cast doubt on the ubiquitously positive claims made by the bank and its supporters yet also provide policy lessons for countries that are either in the inception stages of establishing their own ecas or are now placing greater importance on eca financing in encouraging exports

growth inequality and poverty looking beyond averages the evidence is compelling that the poor in developing countries do typically share in the gains from rising aggregate affluence and in the losses from aggregate contraction but how much do poor people share in growth do they gain more in some settings than others do some gain while others lose does pro poor growth mean more or less aggregate growth recent theories and evidence suggest some answers but deeper microeconomic empirical work is needed on growth and distributed change only then will we have a firm basis for identifying the specific policies and programs needed to complement and possibly modify growth oriented policies

dynamic environmental performance analysis a malmquist index approach abstract this article presents a general framework for dynamic environmental performance analysis by generalizing the approach proposed by kuosmanen and kortelainen kuosmanen t kortelainen m 2005 measuring eco efficiency of production with data envelopment analysis journal of industrial ecology 9 4 59 72 from a static to a dynamic setting for this purpose we construct an environmental performance index epi by applying frontier efficiency techniques and a malmquist index approach compared to other dynamic environmental productivity and efficiency analysis approaches based on these methods our approach builds on the standard definition of eco efficiency as it is presented in the ecological economics literature recognizing the importance to analyze the sources of environmental performance changes we show how changes in overall environmental performance can be decomposed into changes in relative eco efficiency and shifts in environmental technology respectively we apply the presented technique at the macro level to dynamic environmental performance analysis of 20 member states of the european union in 1990 2003 according to the results environmental technical change mostly explains the improvement in overall environmental performance while relative eco efficiency change has been minor for most countries during the sample period

towards indicators of sustainable development for firms a productive efficiency perspective sustainable development can be reflected by various economic social and environmental factors that are closely interconnected with each other and with the additional dimension of time which stresses the long term perspective of several factors due to their central role in human activities and development firms should play an important part in the attainment of sustainability goals the purpose of this paper is to contribute to the methodology of indicators that allow for the assessment of business participation into sustainable development a fundamental standpoint adopted is to view economic social and environmental efficiency as a necessary but not sufficient step towards sustainability to work out indicators we build on both the concepts of cost benefit analysis and the principles of productive efficiency we assume that we have observations on economic social and environmental factors for a set of decision making units dmus e g firms in an industrial sub sector the efficiency of each dmu is computed from a set of observed data using mathematical programming techniques resulting in dmus that are efficient and define the efficiency frontier among the set of dmus and dmus that are inefficient to cope with the multidimensionality of sustainable development it is important not to base decisions on one unique aggregate sustainability indicator instead it is suggested to develop two or three partial indicators that stress different aspects of the problem the proposed indicators could be used as an aid to detect so called factors of unsustainability and hence to provide for recommendations as to the regulations and incentives or managerial practices that will contribute to overall sustainability c 1999 elsevier science b v all rights reserved

production consumption and general equilibrium with physical constraints abstract this paper analyzes the consequences of integrating the conservation laws of mass and energy into the microeconomic models of production consumption and general equilibrium we show that abstract models and especially general equilibrium theory are consistent with these physical constraints but most applied and environmental economic models are not we analyze the consequences of physical conservation laws for substitution possibilities and show that these constraints limit the number of independent substitution processes but not the value of the substitution elasticities finally we propose a method for integrating physical constraints into static microeconomic models with a minimum of changes

cross constrained measuring the cost environment efficiency in material balance based frontier models frontier models based on the material balance principle mbp constitute a major group of environmentally adjusted efficiency methods that produce environmental and economic outcomes but fail to integrate them with measures of allocative efficiency in order to perform a joint cost environmental efficiency analysis drawing insight from the literature on multi criteria analysis the objective of this paper is to extend the mbp framework to new measures of cross constrained cost and environmental allocative efficiency using data envelopment analysis dea cross constrained measures seek for efficiency improvement in one of the two relevant criteria cost and environment consistent with given levels of both production and the outcome of the other criteria the incorporation of these measures into the mbp framework provides an extra decomposition of allocative efficiency in efficiency gains that involve an economic environmental trade off and those that do not the proposed approach is illustrated with an application geared to assessing the efficiency of a sample of greenhouse horticultural production units in almeria spain the results for this case show that it is possible to increase environmental allocative efficiency by up to 34 on average without incurring additional costs

between ostrom and nordhaus the research landscape of sustainability economics abstract we survey the emerging research area of sustainability economics through a quantitative full text analysis of peer reviewed journal publications from 1987 to 2013 to identify relevant contributions we draw on existing definitions of sustainability economics for a keyword based identification strategy a combined focus on a the human nature relationship b the long term uncertain future c normative orientation towards sustainability and d economic analysis our analysis of a random subsample of 343 relevant papers reveals that i sustainability economics is a rapidly developing research area ii while theoretical contributions shaped the area in earlier years applied work now constitutes the largest share of contributions iii the research landscape can be clustered into eleven research clusters these range from participatory governance of social ecological systems associated with the work of elinor ostrom to questions of intertemporal allocation and distribution applied to climate economics associated with the work of william nordhaus iv the research area is broad in scope and heterogeneous and there is relatively little interaction between important clusters v relevant contributions are published in more than 100 journals ten journals publish half of all contributions led by ecological economics and 40 appear in non economics journals underscoring the importance of interdisciplinary dialogue

analysis of environmental efficiency variations a nutrient balance approach recent literature has argued that environmental efficiency ee which is built on the materials balance mb principle is more suitable than other ee measures in situations where the law of mass conversation regulates production processes in addition the mb based ee method is particularly useful in analysing possible trade offs between cost and environmental performance identifying determinants of mb based ee can provide useful information to decision makers but there are very few empirical investigations into this issue this article proposes the use of data envelopment analysis and stochastic frontier analysis techniques to analyse variation in mb based ee specifically the article develops a stochastic nutrient frontier and nutrient inefficiency model to analyse determinants of mb based ee the empirical study applies both techniques to investigate mb based ee of 96 rice farms in south korea the size of land fertiliser consumption intensity cost allocative efficiency and the share of owned land out of total land are found to be correlated with mb based ee the results confirm the presence of a trade off between mb based ee and cost allocative efficiency and this finding favouring policy interventions to help farms simultaneously achieve cost efficiency and mp based ee

how robust is a poverty profile comparison of poverty such as when poverty is greatest typically matter far more for policy choices than do aggregate measures of poverty such as how many people are deemed poor the authors examine alternative methods for constructing poverty profiles focusing on their internal consistency and appropriateness for guiding policy none is perfect but some methods appear to be preferable to others when the aim is to inform policies for fighting absolute consumption poverty a case study on indonesia reveals that the country s regional and sectoral poverty profile is highly sensitive to some aspects of measurement but quite robust to others

the control of export credit subsidies and its welfare consequences a two stage bertrand duopoly model demonstrates how the sequence of firm and government actions can explain the origins of export credit subsidies and can affect the welfare consequences of international agreements to adopt subsidy rate ceilings firms act first by stating prices in applications for export credit and can induce positive subsidies by inflating the prices the subsidies transfer rents from governments to firms without changing welfare defined as profits less subsidy expenditures governments become the first to act by adopting subsidy rate ceilings that bind ceilings cause firms to lower prices such that if a positive ceiling binds welfare falls

value standards in sub sustainable development on limits of ecological economics abstract sustainable development is hard to conceptualize as an economic problem and an economic problem is also ambiguous thus there is room for several kinds of ecological economics this paper analyses different ways of relating ecological and economical thinking to each other and how expertise in these fields relates to politics available methods are delimited in scope where some are suitable for the analysis of sustainable development and others are not it is concluded that the promotion of sustainable development as a basic value assumes an explicit value strategy it is argued that neoclassical economics for example cost benefit analysis is suitable for analysis of sustainable development only as a special case and alternatives are at hand for other cases to illustrate a non neoclassical analysis an empirical investigation using the sustainable development records approach is briefly reported upon

an aggregate resource efficiency perspective on sustainability a sustainable value application to the eu 15 countries the sustainable value approach integrates the efficiency with regard to environmental social and economic resources into a monetary indicator it gained significant popularity as evidenced by diverse applications at the corporate level however its introduction as a measure adhering to the strong sustainability paradigm sparked an ardent debate this study explores its validity as a macroeconomic strong sustainability measure by applying the sustainable value approach to the eu 15 countries concretely we assessed environmental social and economic resources in combination with the gdp for all eu 15 countries from 1995 to 2006 for three benchmark alternatives the results show that several countries manage to adequately delink resource use from gdp growth furthermore the remarkable difference in outcome between the national and eu 15 benchmark indicates a possible inefficiency of the current allocation of national resource ceilings imposed by the european institutions additionally by using an effects model we argue that the service degree of the economy and governmental expenditures on social protection and research and development are important determinants of overall resource efficiency finally we sketch out three necessary conditions to link the sustainable value approach to the strong sustainability paradigm

redefining innovation eco innovation research and the contribution from ecological economics while innovation processes toward sustainable development eco innovations have received increasing attention during the past years theoretical and methodological approaches to analyze these processes are poorly developed against this background the term eco innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development technological social and institutional innovation secondly the potential contribution of neoclassical and co evolutionary approaches from environmental and innovation economics to eco innovation research is discussed three peculiarities of eco innovation are identified the double externality problem the regulatory push pull effect and the increasing importance of social and institutional innovation while the first two are widely ignored in innovation economics the third is at the least not elaborated appropriately the consideration of these peculiarities may help to overcome market failure by establishing a specific eco innovation policy and to avoid a technology bias through a broader understanding of innovation finally perspectives for a specific contribution of ecological economics to eco innovation research are drawn it is argued that methodological pluralism as established in ecological economics would be very beneficial for eco innovation research a theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments and the experience gathered in ecological economics integrating ecological social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes 2000 elsevier science b v all rights reserved

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

public export credit guarantees and foreign trade structure evidence from austria foreign trade is usually not based on cash transactions but rather sales on credit are the rule the resulting monitoring costs for lenders and the risk of default on accounts receivable are part of the costs associated with cross border goods transactions relative to domestic trade credit cross border credit creates trade barriers due to differences in language business practice jurisdiction and payment enforceability between trading partners export credit insurance has long been a domain of public export credit agencies only since the early 1980s private insurance is gaining ground using disaggregated panel data for goods exports from austria over the period 1996 to 2002 we show that public export credit guarantees have a less than proportional positive effect on international trade volume they predominantly affect the country structure of foreign trade but leave the industry specialisation almost unchanged

optimal environmental taxes and standards implications of the materials balance abstract this paper investigates the implications of the materials balance for optimal environmental policy we find that neglecting the materials emissions relationship as is common in models of optimal environmental regulation implies biases whose sign depends on the regulatory instrument chosen when emissions are regulated through an emission tax the seemingly optimal tax is too high when regulation proceeds through the use of an emission standard the seemingly optimal standard is too lax

education in a crisis abstract the year 1998 saw the onset of a major economic and financial crisis in indonesia gdp fell by 12 that year the effect on education of the next generation is examined on average household spending on education declined most dramatically among the poorest households spending reductions were particularly marked in poor households with more young children while there was a tendency to protect education spending in poor households with more older children the evidence on school enrollments mirrors these findings poor households apparently sought to protect investments in the schooling of older children at the expense of the education of younger children

not measuring sustainable value at all a response to kuosmanen and kuosmanen abstract in their article in this issue of ecological economics kuosmanen and kuosmanen kuosmanen t and kuosmanen n this issue how not to measure sustainable value and how one might ecological economics aim to criticise the measurement of sustainable value as proposed in our previous research by adopting a production perspective and based on a productive efficiency analysis they claim that the proposed way of measuring sustainable value represents an invalid simplification that rests on restrictive and unrealistic assumptions our response is to show that their argument rests on a fundamental misspecification of the sustainable value approach we identify three conceptual misfits a mismatch in the perspective of the analysis a misspecification of opportunity costs and the irrelevance of production functions ultimately kuosmanen and kuosmanen s train of thought rests entirely within the realm of productive efficiency analysis whereas sustainable value builds on the foundations of financial economics and consequently adopts a macro rather than a firm perspective it is thus not surprising that the findings of kuosmanen and kuosmanen appear to contradict the sustainable value approach however this is due to their fundamental misspecification of the sustainable value approach as a result rather than providing novel insights into how sustainable value might be measured in a better way they do not measure sustainable value at all

geographic poverty traps a micro model of consumption growth in rural china how important are neighbourhood endowments of physical and human capital in explaining diverging fortunes over time for otherwise identical households in a developing rural economy to answer this question we develop an estimable micro model of consumption growth allowing for constraints on factor mobility and externalities whereby geographic capital can influence the productivity of a household s own capital our statistical test has considerable power in detecting geographic effects given that we control for latent heterogeneity in measured consumption growth rates at the micro level we find robust evidence of geographic poverty traps in farm household panel data from post reform rural china our results strengthen the equity and efficiency case for public investment in lagging poor areas in this setting copyright 2002 john wiley sons ltd

does corporate social responsibility make over educated workers more productive this article provides first evidence on whether corporate social responsibility csr influences the productivity effects of over education by relying on detailed belgian linked employer employee panel data covering the period 1999 2010 our empirical results exhibit a positive and significant impact of over education on firm productivity moreover they suggest that the effect of over education is positively enhanced when the firm implements a csr process especially when it aims to have i a good match between job requirements and workers educational level ii a diverse workforce in terms of gender and age and iii a long term relationship with its workers when focussing on required education and over education the results suggest that csr besides representing an innovative and proactive approach for the firms stakeholders may also be beneficial for the firm itself through a bigger increase in productivity for each additional year of required education or over education

an activity analysis model of the environmental performance of firms application to fossil fuel fired electric utilities the productivity of firms when some outputs pollution are undesirable has been studied in the literature for some time in this paper we introduce an environmental performance indicator based on the decomposition of overall factor productivity into a pollution index and an input output efficiency index this indicator is compared to the more conventional jaggi and freedman 1992 model results are given for illustrative purposes using data from u s fossil fuel fired electric utilities the rankings of the utilities obtained with the two models show significant divergence which is due to the different ways in which the undesirable outputs are dealt with as well as due to the different possible tradeoffs between the pollutants released into the atmosphere and the resources used as inputs

capturing the least costly way of reducing pollution a shadow price approach abstract the production analysis literature is increasingly concerned with estimating marginal abatement costs yet most studies do not emphasize the ways in which pollutants may be reduced and their costs which makes them unable to identify the least costly compliance strategy this paper utilizes the materials balance principle to relate pollution to the employment of material inputs a production model which allows input and output substitution downscaling of operations pollution control and emission permits purchases as compliance strategies is proposed and the implications of joint and non joint pollution controls for the trade off between pollutants and desirable outputs are considered marginal abatement costs reflecting the least costly way of compliance are derived by exploiting the duality between the directional distance function and the profit function

how not to measure sustainable value and how one might abstract sustainability is a complex multidimensional concept that entails economic environmental and social aspects the sustainable value sv method developed by f figge and t hahn ecol econ 48 2004 173 187 is one of the most promising attempts to measure sustainability performance of firms sv measures corporate contributions to sustainability by valuing resource use based on the opportunity cost which must be estimated this paper critically examines figge and hahn s estimator for opportunity cost and shows that the proposed estimator rests on a number of strong unrealistic assumptions evidence from monte carlo simulations conducted by authors shows that the proposed estimator performs very poorly even under ideal conditions having identified shortcomings in the sv method we review some econometric approaches with a proven statistical foundation which might be usefully applied in the present context

can high inequality developing countries escape absolute poverty do the poor face the same prospects for escaping poverty in high inequality developing countries as in low inequality countries is it possible for inequality to be so great as to stifle prospects of reducing absolute poverty even when other initial conditions and policies are favorable to growth household survey data for developing countries suggest that initial distribution does affect how much the poor share in rising average incomes higher initial inequality tends to reduce growth s impact on absolute poverty by the same token higher inequality diminishes the adverse impact on the poor of general economic contraction combining this evidence with that from recent investigations of inequality s effect on growth the author finds that if inequality is high enough countries that would have very good growth prospects at low levels of inequality may see little or no overall growth and little progress in reducing poverty or even a worsening on both counts the data the author uses suggest that such cases do occur the precision with which key parameters have been estimated makes it difficult to say with confidence how common such cases are but they appear to be in the minority what appear to be the best available estimates suggest that about one fifth of the spells between surveys he analyzed were cases in which poverty was rising yet positive growth in the mean and hence falling poverty is predicted at zero inequality inequality can be high enough to result in rising poverty despite good underlying growth prospects

justifying the incorporation of the materials balance principle into frontier based eco efficiency models frontier based models are an alternative to traditional eco efficiency ratio indicators this paper considers two different types environmentally adjusted production efficiency models and frontier eco efficiency models and tries to find justification for incorporating the materials balance principle mbp in them similar importance is attached to the economic and environmental outcomes of a production process like economic outcomes can be derived from inputs and outputs and respective prices some cases allow for deriving environmental outcomes from the production function with the mbp after an overview of attempts to incorporate environmental issues in production efficiency models and some reflections why mbp has been neglected in environmental economics and production efficiency analysis the paper gives basic principles to incorporate the mbp in conventional production efficiency methods and shows how this adjustment leads to a more diversified diagnosis of eco efficiency finally potentialities and bottlenecks are discussed exploiting the mbp in production efficiency and eco efficiency analysis will facilitate more pro active eco efficiency research

environmental regulations environmental governance efficiency and the green transformation of china s iron and steel enterprises abstract based on micro level enterprise panel data from 2005 to 2014 a slack based global data envelopment analysis dea model and a global malmquist luenberger index model are used to calculate the environmental governance efficiency ege of china s iron and steel enterprises ises then the different effects of two types of environmental regulation on ege of china s ises are analysed the results show that the overall level of ege for china s ises has remained low over the past 10 years the total factor environmental governance efficiency tfege presents a decreasing trend from 2005 to 2014 and the decline in tfege is mainly attributed to the technical progress change index gtpch moreover the bootstrap dea method is used for bias correction and the correction efficiency values are all within the confidence interval improving the accuracy of ege evaluation the regression analysis results show that different types of environmental regulations exert heterogeneous effects on tfege the relationship between market incentive environmental regulation and tfege has an inverted u shaped implying that although market incentive environmental regulation may improve the tfege in the short term continuously increasing this intensity would inhibit it however command control environmental regulation and tfege have a positive but not significant relationship
