total factor productivity and the measurement of technological change tfp is interpreted in the literature in different mutually contradictory ways changes in tfp are shown to measure not technological change only the super normal returns to investing in such change returns that exceed the full opportunity cost of the activity thus in the limit technological change can proceed with unchanged tfp measuring the effects of technological change instead requires counterfactual estimates reasons why changes in tfp are imperfect measures of super normal returns are also studied reasons connected with the timing of output responses the treatment of r d in the national accounts the omission of resource inputs and two types of aggregation la productivite totale des facteurs et la mesure du changement technologique la productivite totale des facteurs ptf est interpretee dans la litterature de manieres differentes et mutuellement contradictoires on montre que les changements dans la ptf ne mesurent pas le changement technologique mais seulement les rendements supra normaux sur les investissements dans de tels changements des rendements qui depassent le plein cout d opportunite de cette activite donc a la limite le changement technologique peut proceder sans que la ptf change mesurer les effets du changement technique reclame des evaluations d hypotheses de rechange les raisons pour lesquelles les changements dans la ptf sont des mesures imparfaites des rendements supra normaux sont aussi etudiees raisons connectees avec la reponse des niveaux de production le traitement de la r d dans les comptes nationaux l omission des intrants de ressources et deux types d agregation

from multi utility to cross utilities the challenges of cross sectoral entrepreneurial strategies in a german city in the water and energy sectors projects geared towards new forms of cross sectoral functioning have boomed in most european countries over the past decade and have deeply transformed the ecology

a proposal for integration of the ecosystem water food land energy ewfle nexus concept into life cycle assessment a synthesis matrix system for food security ensuring secure access to food and energy worldwide relies on win win share of sectoral use of constrained natural resources such as land and water taking also into account the crucial role of ecosystems and their services the increase in global population and the related growing demand for food and other services are exerting unsustainable pressures on natural resources compromising their use within the ecosystems carrying capacity progressively studies and initiatives have been developed with the aim of identifying win win share strategies which may compensate the sectoral demands of natural resources addressing the need of a holistic and interdisciplinary nexus approach in this study thus emphasizing the importance of a holistic approach and highlighting the fundamental role of ecosystems we propose a synthesis matrix system that describes the complex and closely bound relationship between natural resources use for food specifically water land energy defined as ecosystem service flows in our matrix system and ecosystems along the lines of the concept of ecosystem water food land energy nexus the synthesis matrix system could be defined for different scales both from the global to the local scale and has been designed to include impacts and nexus with climate change the matrix aims at integrating quantitative and qualitative aspects which are often neglected in traditional approaches of impact assessment the complexity of the interactions between the different components of the nexus requires relying not only on quantitative evidences but also on expert judgment a sensitivity check has been conducted to illustrate how to verify the convergence of expert judgment from different experts moreover being the matrix meant for supporting holistic assessment of supply chain in the present study the integration of the matrix within life cycle assessment lca is proposed however in order to support the analysis of interconnections among impacts further methodological development of the lca methods is needed an illustrative example related to the competition for water land and food bioenergy production is depicted the matrices show that there are predominantly negative impacts given by sectoral uses of resources on the provision of ecosystem services an issue that requires most focus on resource efficiency and on the environmental and economic impacts of natural resources use while reducing the trade offs between the sectoral demands

on the life cycle metaphor where ecology and economics diverge abstract there is an attractive analogy between nature and industry based on the similarity of natural functions and certain industrial activities for instance animals ingest eat and digest food finally there are metabolic wastes firms are analogous to organisms in several respects insofar as they consume material resources process digest them and produce output products and excrete wastes firms like organisms also compete with each other for resources curiously enough one of the apparent differences between natural and man made systems is actually not one like the industrial system the natural system does not recycle everything however there are at least four real and important differences between the biosphere ecology and the technosphere economy first there is no primary producer in the economic system analogous to what photosynthesizers play in the biosphere inputs to the economy are mostly natural resources capital services and labor second in the economic system output is a heterogeneous mix of manufactured products and services labor in economics is an input but not an output the economic system recycles much less than the ecological system but utilizes a far greater suite of elements in the biosphere there are no products as such growth is tantamount to accumulation of embodied solar exergy in the form of cellulose sugars lipids and proteins the biosphere produces only wastes and more of itself plus dead matter third in the biosphere there are no markets there is no medium of exchange like money and there is nothing analogous to paid labor exchanges are involuntary i e by predation parasitism or theft fourth evolution in nature is driven by differentiation by random mutations of the genome and darwinian selection based on reproductive success in economics differentiation is based on discovery invention and innovation by intelligent economic agents and selection is based on competition at the individual or firm level either way the economic system is not closely analogous to an ecosystem attempts to use ecological concepts in an economic context are often misleading and unjustified the paper discusses the implications of the eco eco mismatch for resource accounting and life cycle analysis

multi period efficiency and malmquist productivity index in two stage production systems abstract conventional two stage data envelopment analysis dea models measure the overall performance of a production system composed of two stages processes in a specified period of time where variations in different periods are ignored this paper takes the operations of individual periods into account to develop a multi period two stage dea model which is able to measure the overall and period efficiencies at the same time with the former expressed as a weighted average of the latter since the efficiency of a two stage system in a period is the product of the two process efficiencies the overall efficiency of a decision making unit dmu in the specified period of time can be decomposed into the process efficiency of each period based on this decomposition the sources of inefficiency in a dmu can be identified the efficiencies measured from the model can also be used to calculate a common weight global malmquist productivity index mpi between two periods in that the overall mpi is the product of the two process mpis the non life insurance industry in taiwan is used to verify the proposed model and to explain why some companies performed unsatisfactorily in the specified period of time

electoral systems and public spending we study the effects of electoral institutions on the size and composition of public expenditure in oecd and latin american countries we emphasize the distinction between purchases of goods and services which are easier to target geographically and transfers which are easier to target across social groups we present a theoretical model in which voters anticipating government policymaking under different electoral systems have an incentive to elect representatives more prone to transfer public good spending in proportional majoritarian systems the model also predicts higher total primary spending in proportional majoritarian systems when the share of transfer spending is high low after dee ning rigorous measures of proportionality to be used in the empirical investigation we e nd considerable support for our predictions

the impact of environmental expenditures on performance in the u s chemical industry abstract this study analyzes chemical industry companies with environmental expenditures to determine which ones have better financial performance in addition this study uses data envelopment analysis to evaluate the efficiency of firms with and without environmental expenditures this study also utilizes the malmquist productivity index mpi to analyze firms productivity change and a bootstrap method to test whether the indexes are statistically significant finally this study divides chemical industry companies into three main categories based on their products the results of this study provide significant evidence of a relationship between environmental expenditures and financial performance the findings suggest that firms with environmental expenditures have better efficiency and productivity hence the study encourages companies in the industry to put more effort into protecting the environment that can be through practicing cleaner production to create higher benefits

radial and non radial decompositions of profit change with an application to indian banking abstract grifell tatje and lovell grifell tatje e lovell c a k 1999 profits and productivity management science 45 1177 1193 made significant contributions to the literature on the extended radial dea framework by decomposing profit change into six mutually exclusive components their approach however poses two basic problems first the radial estimates on these components might give conflicting signals about the direction of profit change after the full radial efficiencies are achieved when slacks are present second evaluations of these components using base period prices as weights can be potentially misleading to address these concerns we first introduce non radial dea models and then provide a few strong theoretical arguments in favor of using as weights either current period prices or an average price covering both periods to value the contributions of each of these components the indian banking sector is taken as a case study to illustrate the radial and non radial decompositions of profit change so as to empirically examine the role of competition on profit change and its drivers our broad empirical results are as follows first radial and non radial models yield diametrically opposite results on the contributions of various components second the increasing efficiency change trends in all ownership groups after 2002 indicate that the government reform process instituted on the banking industry has had a favorable effect on the performance of the indian banking sector third despite the fact that nationalized banks are the oldest banks their output and resource allocation behaviors do not reflect their learning experience

sustainability meta labelling an effective measure to facilitate more sustainable consumption and production abstract arguably one of the most prominent measures to facilitate more sustainable consumption and production has been the instrument of product labelling but with a plethora of labelling schemes having been implemented by various actors over the last decade many now accuse them of being confusing rather than facilitating as a result governments in france uk and germany as well as businesses such as walmart and non governmental organisations like wwf have begun to consider seriously the implementation of some form of meta scheme that condenses existing product labels and other communication measures into an overarching sustainability message yet so far in depth studies on the potential institutionalisation of a sustainability meta labelling scheme are missing drawing upon a novel theoretically integrative framework that combines theoretical arguments of constructivist institutionalism and institutional entrepreneurship with the concept of legitimacy this paper addresses this gap by exploring how the notion of sustainability meta labelling has so far been discussed and investigating the prospects for such an overarching scheme to become institutionalised empirically the paper bases on documentary analysis and elite interviews focussed on case studies of four existing product labelling schemes eu ecolabel eu energy label marine stewardship council and fairtrade label as well as the notion of sustainability meta labelling legitimacy constructions are demonstrated rather than shown to be highly dynamic and oftentimes inherently conflicting many of these conflicts thereby appear to be likely to increase rather than decrease with the implementation of an overarching sustainability meta labelling scheme in a sense this study shows that the very issue that is claimed to drive the establishment of a sustainability meta labelling scheme the different interpretations of the sustainable development concept through different product labels might in fact pose one of the main challenges for its institutionalisation and effectiveness in facilitating more sustainable consumption and production

bridging the gap between partial and total factor productivity measures using directional distance functions technical dependencies as well as data constraints limit our ability to allocate inputs across sectors and hence our ability to measure sectoral productivity we adapt a directional measure of efficiency to the measurement of sector specific productivity that does not require allocating all inputs across sectors applied to the agricultural sector of a group of countries the results show important differences in livestock and crops productivity growth commonly used partial factor productivity measures for livestock and crops tend to overestimate productivity growth in most developing countries while underestimating it in european countries

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

efficiency and technical progress sources of convergence in the spanish regions the paper analyses the contribution of efficiency as a mechanism of labour productivity convergence taking as the unit of analysis the spanish regions in the period 1964 1993 using the stochastic frontier approach a translogarithmic production function is estimated for the different sectors of the spanish regional economy demonstrating on this basis the existence of substantial differences in efficiency between sectors as well as between regions with regard to convergence the results obtained indicate that at aggregate level the convergence observed in labour productivity is explained by the faster growth of the capital labour ratio of the initially poorer regions and the contribution of technical change and the efficiency hence by the convergence of tfp however the information by sectors shows different results thus on the one hand the importance of the convergence in production per employee is seen in all sectors except agriculture and on the other it is observed that technical change is a

the evolution and main determinants of productivity in brazilian electricity distribution 1998 2005 an empirical analysis abstract this paper estimates changes in the productivity of the brazilian electricity distribution sector using data envelopment analysis dea on a panel of 18 firms from 1998 to 2005 the study decomposes the productivity change of these distribution firms in terms of technical efficiency scale efficiency and technical progress this exercise aims to help the understanding of the main determinants of the evolution of productivity focusing its relationship with the restructuring process implemented in the 1990s tfp index records a yearly positive growth rate of 1 3 in the whole period under analysis for all firms technical change was the main component behind this evolution with an average growth of 2 1 per year while technical efficiency presented a yearly negative performance of 0 8 the results prove that in general terms the incentives generated in the reform process do not seem to have led the firms to behave in a more efficient manner

the modern history of exchange rate arrangements a reinterpretation we develop a novel system of reclassifying historical exchange rate regimes one key difference between our study and previous classifications is that we employ monthly data on market determined parallel exchange rates going back to 1946 for 153 countries our approach differs from the imf official classification which we show to be only a little better than random it also differs radically from all previous attempts at historical reclassification our classification points to a rethinking of economic performance under alternative exchange rate regimes indeed the breakup of bretton woods had less impact on exchange rate regimes than is popularly believed

the impact of federal spending on house election outcomes while it is widely believed by academics politicians and the popular press that incumbent members of congress are rewarded by the electorate for bringing federal dollars to their district the empirical evidence supporting that claim is extremely weak one explanation for the failure to uncover the expected relationship between federal spending and election outcomes is that incumbents who expect to have difficulty being reelected are likely to exert greater effort in obtaining federal outlays since it is generally impossible to adequately measure this effort the estimated impact of spending is biased downward because of an omitted variable bias we address this estimation problem using instrumental variables for each house district we use spending outside the district but inside the state containing the district as an instrument for spending in the district federal spending is affected by a large number of actors e g governors senators mayors and other house members in the state delegation

the role of exergy in energy policy making abstract this paper deals with the utilization of exergy as an efficient tool for energy policy making applications since exergy is a measure of quantity and quality of the energy sources unlike energy which is only about the quantity in addition energy and exergy concepts are evaluated for various actual processes and the role of exergy is discussed for energy and environment policy making activities from several key perspectives e g quality energy conservation environment economy and sustainable development the results of this study exhibit that the potential usefulness exergy in addressing and solving environmental problems as well as attaining sustainable development is crucial

productivity growth and biased technological change in hydroelectric dams abstract this paper analyses productivity growth and the nature of technical change in a sample of portuguese hydroelectric generating plants over the period 2001 to 2008 in a first step we employ the luenberger productivity indicator to estimate and decompose productivity change a malmquist productivity index is also used for a comparative purpose the results paint a picture of mixed productivity performance in the portuguese energy sector the first decomposition underlines that in average the productivity variation is explained by the technological change then in a second step we analyse the nature of this technical change by using the recent concept of parallel neutrality briec et al 2006 we observe a global shift in the best practice frontier as well as in the evidence of input bias in technical change

considering the energy water and food nexus towards an integrated modelling approach the areas of energy water and food policy have numerous interwoven concerns ranging from ensuring access to services to environmental impacts to price volatility these issues manifest in very di

on the vote purchasing behavior of incumbent governments a couple of months before the swedish election in 1998 the incumbent government distributed 2 3 billion sek to 42 out of 115 applying municipalities this was the first wave of a four year long grant program intended to support local investment programs aimed at an ecological sustainable development this temporary grant program differs from traditional intergovernmental grants in several aspects most importantly in the sovereign decision making power given to the incumbent central government in this paper we investigate whether there were any tactical motives behind the distribution of these grants we find support for the hypothesis that the incumbent government used the grant program under study in order to win votes in particular we find strong support for the lindbeck weibull dixit londregan model in which parties distribute transfers to regions where there are many swing voters this result is statistically as well as economically significant we do however not find any support for the model that predicts that the incumbent government transfer money to its own supporters

more heat and light abstract one hundred years before the advent of modern power systems william blake in the marriage of heaven and hell argued with the devil asserting that energy is eternal delight that delight however remains beyond the reach of the two to three billion of people disadvantaged by a lack of modern energy services a number that has remained relatively unchanged over recent decades this is arguably the most disturbing of insights from an examination of global energy use trends and a simple clear justification for a political prioritisation of the issue it is widely accepted that a lack of access to energy services is a fundamental hindrance to human social and economic development addressing it comprehensively would have enormous multiple benefits however current efforts are woefully insufficient in scale scope and design and attempting to address the issue solely as part of wider poverty reduction policies is likely to be sub optimal we discuss energy policy with a focus on energy security as an effective vehicle for large scale action in providing modern clean energy services to this end we outline specific and limited examples of where international cooperation could play a role supporting national actions and ensuring universal access

data envelopment analysis of different climate policy scenarios abstract recent developments in the political scientific and economic debate on climate change suggest that it is of critical importance to develop new approaches able to compare policy scenarios for their environmental effectiveness their distributive effects their enforceability their costs and many other dimensions this paper discusses a quantitative methodology to assess the relative performance of different climate policy scenarios when accounting for their long term economic social and environmental impacts the proposed procedure is based on data envelopment analysis here employed in evaluating the relative efficiency of eleven global climate policy scenarios the methodology provides a promising comparison framework it can be seen as a way of setting some basic guidelines to frame further debates and negotiations and can be flexibly adopted and modified by decision makers to obtain relevant information for policy design three major findings emerge from this analysis i stringent climate policies can outperform less ambitious proposals if all sustainability dimensions are taken into account ii a carefully chosen burden sharing rule is able to bring together climate stabilisation and equity considerations and iii the most inefficient strategy results from the failure to negotiate a post 2012 global climate agreement

assessing productivity changes in uk hospitals reflecting technology and input prices in this study malmquist productivity indexes are used to evaluate the performance of acute hospitals in the uk over the period after the introduction of the internal market in the national health service in 1991 the indexes are computed using nonparametric programming known as data envelopment analysis and they are decomposed into multiple component measures to give insights into the trends in hospital performance overall it is found that productivity regressed in the year after the reforms but progressed thereafter so that overall there was a net progress both as far as the inputs and costs are concerned productivity progress is mainly due to overall efficiency progress which in turn is mostly attributed to allocative efficiency improvements technical change resulted in a small reduction in the amount of inputs used but also at higher production costs because of a worsening in the match between input mixes and relative input prices however it is suggested that the gains in productivity are not

attribution error in economic voting evidence from trade shocks this article exploits the international transmission of business cycles to examine the prevalence of attribution error in economic voting in a large panel of countries from 1990 to 2009 we find that voters on average exhibit a strong tendency to oust the incumbent governments during an economic downturn regardless of whether the recession is home grown or merely imported from trading partners however we find important heterogeneity in the extent of attribution error a split sample analysis shows that countries with more experienced voters more educated voters and possibly more informed voters all conditions that have been shown to mitigate other voter agency problems do better in distinguishing imported from domestic growth jel e3 e6

a quest for the economics of sustainability and the sustainability of economics abstract this paper briefly reviews key insights from natural resource and environmental economics ecological economics and industrial ecology in an effort to identify the major contributions of these fields to the understanding and promotion of sustainable development each is based on overlapping worldviews methods and tools their synthesis and extension subsumed under the rubric of natural economics is suggested as a new thrust in environmental research offering valuable guides to policy making an early illustration of the application of natural economics in new zealand is presented

life cycle uses of water in u s electricity generation water use by the electric power industry is attracting renewed interest as periods and zones of arid weather are increasingly encountered and various regional energy production scenarios are evaluated however there is a scarcity of data on upstream water factors and discrepancies of data from different sources we reviewed previous studies of water use in electricity generation and used full life cycle accounting to evaluate water demand factors both withdrawal and consumption for conventional and renewable electrical power plants our investigation showed that moving to technologies like photovoltaics and wind offers the best option for conserving our water supply we also emphasize the importance of employing a transparent balanced approach in accounting life cycle water usages

the sustainable value approach a clarifying and constructive comment recently the original benchmarking methodology of the sustainable value approach became subjected to serious debate while kuosmanen and kuosmanen 2009b critically question its validity introducing productive efficiency theory figge and hahn 2009 put forward that the implementation of productive efficiency theory severely conflicts with the original financial economics perspective of the sustainable value approach we argue that the debate is very confusing because the original sustainable value approach presents two largely incompatible objectives nevertheless we maintain that both ways of benchmarking could provide useful and moreover complementary insights if one intends to present the overall resource efficiency of the firm from the investor s viewpoint we recommend the original benchmarking methodology if one on the other hand aspires to create a prescriptive tool setting up some sort of reallocation scheme we advocate implementation of the productive efficiency theory although the discussion on benchmark application is certainly substantial we should avoid the debate to become accordingly narrowed next to the benchmark concern we see several other challenges considering the development of the sustainable value approach 1 a more systematic resource selection 2 the inclusion of the value chain and 3 additional analyses related to policy in order to increase interpretative power

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

modelling the diffusion and operation of anaerobic digestions in great britain under future scenarios within the scope of water energy food nexus abstract the paper aims to understand the impacts of the spatial and temporal diffusion of anaerobic digestion ad on the water energy food wef nexus and to quantify the associated environmental social and economic benefits contemporary tight carbon reduction targets urge the need to deploy renewable energy technologies however due to interdependencies across the wef nexus various technologies are beneficial for some but not all sectors this paper quantifies the impacts of future possible ad technology diffusion choices on the environment society and economy this can aid decision makers to identify the potential consequences of various ad alternatives within the next three decades the study considers an integrated wef nexus approach and accounts for the interdependencies within the nexus this was done by developing an agent based model abm and simulating the relations between the main players within the nexus thus examining the upscaling of ad diffusion and its consequences for water consumption energy production transportation landfill use food waste processing and digestate generation three future wef nexus scenarios that reflect potential alternatives of society and technology in great britain up to 2050 were utilised by the abm implementation to test the sensitivity of ad diffusion choices these scenarios describe possible changes to lifestyle governance technologies climate and social structures accounting for the uncertainty associated with such future simulations the monte carlo method was employed to estimate the potential variations in scenario outputs results suggest that decentralisation results in the largest carbon reduction but can incur more costs centralisation consumes 35 more water but produces 37 more energy biogas the paper has visualised the scenario outputs graphically to highlight the consequences of neglecting the inter relationships between environmental social and economic aspects of ad

technical efficiency and productivity analysis in indonesian provincial economies this article estimates inefficiency and total factor productivity tfp across indonesian provinces from 1993 to 2000 indonesia is a large emerging market economy but provinces within the country due to the island structure of the country are more distinct from one another compared to other countries we use a stochastic frontier methodology to estimate inefficiency and tfp we find that tfp fell by an average rate of 7 5 across provinces due to the decrease in technical efficiency in fact the majority of output growth within indonesia is explained by the accumulation of inputs in this sense economic growth within indonesia does not appear to be sustainable without reversing these trends

malmquist productivity indexes and fisher ideal indexes comment fare and grosskopf i992 henceforth abbreviated as fg showed that under some conditions the productivity index defined as the geometric mean of two input based malmquist productivity indexes is equal to the quotient of the fisher input quantity index and the fisher output quantity index both fisher indices can be computed from observed prices and quantities these conditions appear to be so strong that they will almost certainly never be fulfilled in practice this is shown by a careful inspection of fg s proof however under slightly milder but more plausible conditions it can be shown that the quotient of the fisher input index and the fisher output index is a reasonable approximation of the productivity index consider a firm at two time periods t o i with different technologies which are modelled by the input correspondences lt y x x can produce y x c rn yce rm it is assumed that the sets lt y are closed and convex and that inputs are strongly disposable the vectors x yt wt pt t o i denote observed inputs observed outputs observed input prices and observed output prices respectively the productivity index is defined as

time frequency contained co movement of crude oil and world food prices a wavelet based analysis abstract this paper evaluates the association between crude oil prices and world food price indices first within general space and time and then within the combined time frequency sphere monthly price data spanning from january 1990 to february 2016 were used for the analysis the johansen cointegration test conducted within the time domain confirmed the statistically significant cointegrated relationship between crude oil prices and the price indices of food and its sub categories such as dairy cereals vegetable oil and sugar however frequency information was not accounted for to incorporate both the time and frequency features of the data we used a wavelet method that has shown that the world food prices along with the prices of cereals vegetable oils and sugar co move with and are led by crude oil prices results that remain relevant from the short run policy perspective the outcome of toda yamamoto causality confirmed the spillover of crude oil price changes to the world food price index also in the long run the paper ends with the policy implications of these results

total factor carbon emission performance of fossil fuel power plants in china a metafrontier non radial malmquist index analysis article i nfo this paper proposes the metafrontier non radial malmquist co2 emission performance index mnmcpi for measuring dynamic changes in total factor co2 emission performance over time the mnmcpi method allows for the incorporation of group heterogeneity and non radial slack into the previously introduced malmquist co2 emission performance index mcpi we derive the mnmcpi by solving several non radial data envelop ment analysis dea models we decompose the mnmcpi into an efficiency change ec index a best practice gap change bpc index and a technology gap change tgc index and based on the proposed indices we examine the dynamic changes in co2 emission performance and its decomposition of fossil fuel power plants in china for the 2005 2010 period the empirical results show a 0 38 increase in total factor co2 emission performance as a whole and a u shaped mnmcpi curve for the sample period because companies owned by the central government lack innovation and technological leadership the results suggest a missing link in the role of the central government in promoting co2 emission performance

total factor carbon emission performance of the chinese transportation industry a bootstrapped non radial malmquist index analysis this paper proposes a non radial malmquist co2 emission performance index nmcpi for measuring dynamic changes in total factor co2 emission performance over time this index enables the consideration of non radial slacks in the conventional malmquist co2 emission index mcpi the nmcpi is calculated based on a non radial directional distance function derived by several data envelopment analysis dea models furthermore nmcpi could be decomposed into an efficiency change ec index and technological change tc index a bootstrapping approach is conducted to introduce statistical inferences into the nmcpi and its decompositions based on the proposed indices the dynamic co2 emission performance change and its decompositions of the chinese regional transportation industry from 2002 to 2010 are investigated the empirical results demonstrate that the total factor carbon emission performance of the transportation industry as a whole decreased by 32 8 over the period and this reduction was primarily caused by technological decline

eco thermodynamics economics and the second law the laws of physics especially the first and second laws of thermodynamics have significant implications for economic theory the major implications of the first law conservation of mass energy are straightforward and have been discussed at length elsewhere in brief raw material inputs to economic processes are not consumed having been extracted from the environment in the first place they eventually return to the environment as wastes the economic implications of the second law entropy law are far more subtle there is considerable literature initiated by the work of georgescu roegen on the supposed constraints on economic growth imposed by the fact that economic processes utilize low entropy raw materials fossil fuels and high grade metal ores and discard high entropy wastes however as a practical matter the flux of available low entropy energy exergy from the sun is extremely large and certainly adequate to sustain economic activity in the solar system indefinitely even though fossil fuel and metal ore stocks may eventually be exhausted it is argued in this paper that the real economic significance of the second law lies in the fact that exergy is i not conserved and ii is a useful common measure of resource quality as well as quantity applicable to both materials and energy thus exergy can be used to measure and compare resource inputs and outputs including wastes and losses this is potentially important in itself moreover since exergy is not conserved it is truly consumed i e used up in economic processes hence exergy is no less a factor of production than labor or capital this fact has strong implications for economic growth theory especially with regard to assessing the role of technical progress

integrated assessment of water energy ghg emissions tradeoffs in an irrigated lucerne production system in eastern australia robust understanding of possible trade offs and synergies between climate change energy and water sector policies is critical to achieving economically viable and environmentally sound agricultural production systems in a low carbon water constrained economy in which greenhouse gas ghg emissions are penalized and water savings rewarded accurate assessment of the potential costs benefits of investment decisions can help to optimize the economic efficiency of agricultural production while minimizing environmental impacts this paper presents a novel integrated framework based on carbon and water accounting which enables analysis of potential trade offs between water savings energy consumption ghg emissions and economic costs benefits associated with the adoption of new water efficient irrigation technologies the framework was applied to an irrigated lucerne cropping system in eastern australia and compares the costs benefits of old roll line sprinkler irrigation systems against new pressurized systems positive synergies were found with the adoption of the new technology which saved both water and energy use reduced total ghg emissions and resulted in net economic returns across a range of carbon prices the results of this study provide support for an integrated evidence based approach to policy development and strategic decision making and for the prioritization of investments on both economic and environmental grounds

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

deeds not words a cosmopolitan perspective on the influences of corporate sustainability and ngo engagement on the adoption of sustainable products in china to make a business case for corporate sustainability firms must be able to sell their sustainable products the influence that firm engagement with non governmental organizations ngos may have on consumer adoption of sustainable products has been neglected in previous research we address this by embedding corporate sustainability in a cosmopolitan framework that connects firms consumers and civil society organizations based on the understanding of responsibility for global humanity that underlies both the sustainability and cosmopolitanism concepts we hypothesize that firms sustainability engagement and their ngo engagement influence consumer adoption of sustainable products empirically we investigate the adoption of sustainable eco circle products made from recycled fibers marketed by li ning a china based global sportswear brand we apply a stepwise regression approach to test our hypotheses with paper and pencil survey data from 217 chinese consumers we find adoption to be positively associated with consumers sustainability attitude but not with firms sustainability engagement for firm ngo engagement these relationships are reversed adoption is positively associated with firm ngo engagement but not with consumers related attitude our results present a picture of the chinese context in which there is a business case for corporate sustainability if firms words about sustainable product strategies are supported by signals from civil society about firm deeds the results imply that in a chinese context firms need to be particularly aware of the role of ngos when hoping to be rewarded for sustainability

foreign direct investment spillovers and technical efficiency in the indonesian pharmaceutical sector firm level evidence the spillovers of foreign direct investment fdi on domestic firms performances have been highly debated for many years this article contributes to this debate by analysing spillovers effects on technical efficiency of indonesian pharmaceutical sector using a unique unbalanced panel of highly disaggregated at five digit international standard industrial classification isic 210 firms over the period 1990 1995 1001 observations the stochastic production frontier spf and the data envelopment analysis dea based on malmquist productivity indices mpi have been used to test the spillovers effects of fdi on technical efficiency the empirical results from the spf show that foreign firms are more efficient than domestic competitors and the presence of the former increases the inefficiency of the latter similarly the results from the mpi demonstrate that fdi has a negative and significant impact on technical efficiency changes in domestic competitors but generate positive spillovers to domestic s

estimating most productive scale size using data envelopment analysis abstract the relation between the most productive scale size mpss for paparticular input and output mixes and returns to scale for multiple inputs multiple outputs situations is explicitly developed this relation is then employed to extend the applications of data envelopment analysis dea introduced by charnes cooper and rhodes ccr to the estimation of most productive scale sizes for convex production possibility sets it is then shown that in addition to productive inefficiencies at the actual scale size the ccr efficiency measure also reflects any inefficiencies due to divergence from the most productive scale size two illustrations of the practical applications of these results to the estimation of most productive scale sizes and returns to scale for hospitals and stem electric generation plants are also provided emphasize the advantage of this method in examining specific segments of the efficient production surface

eco efficiency of the western taiwan straits economic zone an evaluation based on a novel eco efficiency model and empirical analysis of influencing factors abstract obtaining the most economic benefits while using the least resources and causing the least environmental damage is an urgent and key problem in achieving sustainable development the concept of eco efficiency provides a comprehensive perspective for observing and solving this problem this paper proposes an extended data envelopment analysis model named the win us sbm as a comprehensive eco efficiency evaluation method that can accommodate undesirable outputs all the identification problems of decision making units dmus possible slacks of variables and the problems of an insufficient number of available dmus and intertemporal comparability china s western taiwan straits economic zone wts economic zone is an important regional economic growth center by applying win us sbm and arcgis software we investigated data on the temporal and spatial evolution characteristics of eco efficiency in the wts economic zone for the years 2009 2016 later the global malmquist luenberger index was used to decompose the sources of growth in eco efficiency finally the main driving factors of eco efficiency were explored through a tobit regression analysis the empirical results show that 1 the overall eco efficiency of the wts economic zone had greatly improved increasing by 11 46 annually and the cumulative growth rate of eco efficiency was 110 84 from 2009 to 2016 2 the eastern area had the highest average eco efficiency followed by the western area and the middle area in that order also the growth rate of the middle area ranked first 16 68 whereas the eastern area had the slowest growth in eco efficiency 7 22 3 on the whole the growth of eco efficiency was driven mainly by technological progress and was restricted by the decrease in management level which implies that policy makers should focus on improving management and technical levels 4 high levels of economic development population density market openness and industrial structure had positive effects on the eco efficiency of the wts economic zone whereas energy intensity and expenditure on science and technology had negative impacts

rural household energy consumption and its impacts on eco environment in tibet taking taktse county as an example abstract rural energy consumption causes tremendous damage to eco environment and leads to aberration from a socio economic point of view in many developing countries due to its unique physical features there is a high potential of renewable energies in tibet and traditional biomass energies such as cattle dung firewood and crop residues play very important roles in local household energy usage this special consumption structure do harm not only to eco environment but to rural residents themselves as well basing on the field study and household questionnaires in june 2006 in taktse the article analyzed the rural household energy supply and consumption structure and its impacts on eco environment health and social aspects of 2005 in this case study county results show that traditional biomass energy takes up to almost 70 which leads to a series of serious eco environment problems such as deforestation soil erosion grassland degradation desertification and some other problems such as human beings diseases and loss of time for education and recreation besides natural backgrounds cultural tradition population growth economy reason and policy guidance are other main driving forces of the input output flow of energy environment relationship in rural tibet at last a multilevel policy suggestion of making less use of traditional biomass and invest more resources in solar energy and biogas are put forward

decomposition of the fisher ideal index of productivity a non parametric dual analysis of us airlines data in this paper we offer a non parametric method of decomposing the fisher ideal index of productivity into individual factors measuring i technical efficiency change ii allocative efficiency change iii shift in the cost function iv scale economies due to output change and v an adjustment factor reflecting change in the output attributes cross section data from the us airline industry for the years i 983 and i 984 are utilised in an empirical application illustrating this method the rate of multifactor productivity growth mfpg over time in the single output multiple input case can be measured by the difference in the rates of growth in the quantity of output and the divisia index of input quantity when no technical inefficiency exists this rate of mfpg can be decomposed into two additive components i the rate of technical change measuring the rate of change in the volume of output holding the input bundle unchanged and ii a returns to scale effect showing change in productivity with changes in the input quantities without technical change when technical efficiency varies over time a part of the measured rate of mfpg would be due to efficiency

pollution abatement activities and traditional productivity abstract this study models the joint production of good and bad output production and calculates traditional productivity when bad output production is regulated and when it is unregulated we apply this model to data for u s coal fired electric power plants for 1985 1995 and compare rates of productivity and technical change to gain an understanding of the association between pollution abatement activities and traditional rates of productivity and technical change while traditional productivity and technical change associated with abatement activities decline we conclude they are not statistically significant

regulatory reforms and productivity an empirical analysis of the japanese electricity industry the japanese electricity industry has experienced regulatory reforms since the mid 1990s this article measures productivity in japan s steam power generation sector and examines the effect of reforms on the productivity of this industry over the period 1978 2003 we estimate the luenberger productivity indicator which is a generalization of the commonly used malmquist productivity index using a data envelopment analysis approach factors associated with productivity change are investigated through dynamic generalized method of moments gmm estimation of panel data our empirical analysis shows that the regulatory reforms have contributed to productivity growth in the steam power generation sector in japan

getgreen vietnam towards more sustainable behaviour among the urban middle class abstract in vietnam the middle class is expected to grow from 12 million to 33 million people between 2012 and 2020 the growth causes an increase as well as a shift in consumption products that were not accessible or affordable before will become increasingly so such as cars dishwashers meat products and air conditioning in urban areas the changes are most prominent and so are the side effects increased amounts of waste smog pollution and use of fossil energy or pesticides the main objective of this study was to identify sustainable behaviour that followed or did not follow from the intervention project getgreen vietnam 604 urban middle class consumers participated in a series of sustainable consumption trainings before during and after the trainings quantitative and qualitative data was collected on 90 sustainable actions 64 of the participants self reported to be engaged in a sustainable action before the intervention and this percentage increased to 80 after the group environment and activity based meetings of getgreen vietnam project ggvn were critical for the success of the intervention participants reported that before ggvn certain actions were already habitual as a money saving strategy e g sparse electricity use or food leftovers re use or due to past scarcity e g sparse water use many participants reported the intention to buy sustainable products but fewer participants took action to do so a powerful strategy toward more sustainable consumption in vietnam can be to create more group based activities around the themes of energy and shopping for food a twofold approach is needed that both installs new sustainable consumption patterns and keeps old habits rooted in daily rituals role models should set an example for the young population and consumers and vietnamese producers should be better connected to increase mutual trust and transparency

a stable international monetary system emerges inflation targeting is bretton woods reversed a stable international monetary system has emerged since the early 1990s a large number of industrial and a growing number of developing countries now have domestic inflation targets administered by independent and transparent central banks these countries place few restrictions on capital mobility and allow their exchange rates to float the domestic focus of monetary policy in these countries does not have any obvious international cost inflation targeters have lower exchange rate volatility and less frequent sudden stops of capital flows than similar countries that do not target inflation inflation targeting countries also do not have current accounts or international reserves that look different from other countries this system was not planned and does not rely on international coordination there is no role for a center country the imf or gold it is durable in contrast to other monetary regimes no country has been forced to abandon an inflation targeting regime succinctly it is the diametric opposite of the post war system bretton woods reversed

the effect of incentive reforms upon productivity evidence from the vietnamese rice industry in this study we use region level panel data on rice production in vietnam to investigate total factor productivity tfp growth in the period since reunification in 1975 two significant reforms were introduced during this period one in 1981 allowing farmers to keep part of their produce and another in 1987 providing improved land tenure we measure tfp growth using two modified forms of the standard malmquist data envelopment analysis dea method which we have named the three year window tyw and the full cumulative fc methods we have developed these methods to deal with degrees of freedom limitations our empirical results indicate strong average tfp growth of between 3 3 and 3 5 per cent per annum with the fastest growth observed in the period following the first reform our results support the assertion that incentive related issues have played a large role in the decline and subsequent resurgence of vietnamese agriculture

is inflation in developing countries driven by low productivity or monetary growth abstract this paper investigates whether inflation in developing countries is driven by retrogression in productivity or by monetary expansion our empirical methodology relies on growth accounting non parametric and generalized method of moment techniques results indicate that inflation is primarily driven by monetary growth

on the circular bioeconomy and decoupling implications for sustainable growth abstract this paper explores the existing confusion around the conceptual definitions and interpretations of the term circular bioeconomy the co existence of diametrically opposite interpretations of the concept indicates lack of a serious discussion of its theoretical foundations two narratives on circular bioeconomy are explored in depth i the new economic paradigm based on technological progress the economics of technological promises that seeks perpetual economic growth ii an entropic thermodynamic narrative that reflects on the limits on economic growth imposed by nature the latter narrative makes a distinction between primary secondary and tertiary resource flows and helps to identify what can and cannot be re circulated within the metabolic pattern of social ecological systems adopting the biophysical view it becomes clear that the industrial revolution represented a linearization of material and energy flows with the goal to overcome the low pace and density of biological transformations the required level of productivity of production factors in contemporary developed economies flows per hour of labor and per hectare of land use is orders of magnitude larger than the pace and density of supply and sink capacity of natural processes relying on nature to close the loop will simply slow down the economic process

politics and business cycles in industrial democracies politics alberto alesina influences from political competition on macroeconomic policy are often thought to be a source of economic fluctuations politicians are described as being driven by two not mutually exclusive main motivations they want to be reelected and they harbour political or ideological biases when such theories are confronted with actual cycles in a number of industrial countries the pattern of inflation unemployment output and budget deficits indicates that partisan policy making is a fairly widespread phenomenon with more limited evidence that electoral preoccupations result in major fluctuations the combination of partisanship and electoral cycles may easily result in socially undesirable outcomes in particular the degree of politico institutional stability and the independence of the central bank have a bearing on macroeconomic outcomes these observations raise a number of important questions about the design of political institutions

performance and efficiency in colombia s power distribution system effects of the 1994 reform we assess evolution in performance efficiency and productivity of colombia s power distribution utilities before and after the 1994 regulatory reform that introduced electricity market activities for the power sector in 12 distribution companies from 1985 to 2001 performance is evaluated contrasting changes in mean and median by wilcoxon rank sum and pearson tests on financial and other performance indicators technical efficiency is measured by means of data envelopment analysis dea the nature of the dataset allows the estimation of malmquist productivity index and its evolution in time results show a recovery after the reform in the main performance indicators of profitability partial input productivity and output plant efficiency and productivity increased after the reform mainly in the largest utilities used as benchmarks in the dea efficiency scores measures meanwhile the less efficient power distribution companies did not improved after the reform and were not able to undertake plant restructuring to catch up in plant efficiency with respect to the pareto efficient input allocations econometric results on dea efficiency scores suggest a positive effect of policy reform

empiricism in ecological economics a perspective from complex systems theory economies are open complex adaptive systems far from thermodynamic equilibrium and neo classical environmental economics seems not to be the best way to describe the behaviour of such systems standard econometric analysis i e time series takes a deterministic and predictive approach which encourages the search for predictive policy to correct environmental problems rather it seems that because of the characteristics of economic systems an ex post analysis is more appropriate which describes the emergence of such systems properties and which sees policy as a social steering mechanism with this background some of the recent empirical work published in the field of ecological economics that follows the approach defended here is presented finally the conclusion is reached that a predictive use of econometrics i e time series analysis in ecological economics should be limited to cases in which uncertainty decreases which is not the normal situation when analysing the evolution of economic systems however that does not mean we should not use empirical analysis on the contrary this is to be encouraged but from a structural and ex post point of view

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

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

how do budget deficits and economic growth affect reelection prospects evidence from a large panel of countries conventional wisdom is that good economic conditions and expansionary fiscal policy help incumbents get reelected but this has not been tested in a large cross section of countries we test these arguments in a sample of 74 countries over the period 1960 2003 we find no evidence that deficits help reelection in any group of countries developed and less developed new and old democracies countries with different government or electoral systems and countries with different levels of democracy in developed countries and in old democracies election year deficits actually reduce the probability that a leader is reelected with similar although smaller negative electoral effects of deficits in the earlier years of an incumbent s term in office higher growth rates of real gdp per capita raise the probability of reelection only in the less developed countries and in new democracies but voters are affected by growth over the leader s term in office rather than in the election year itself and apparently only by growth not attributed to global growth low inflation is rewarded by voters only in the developed countries the effects we find are not only statistically significant but also quite substantial quantitatively we also suggest how the absence of a positive electoral effect of deficits can be consistent with the political deficit cycle found in new democracies

the misleading effect of energy efficiency information on perceived energy friendliness of electric goods the european union energy label informs consumers at the point of sale about the energy efficiency and electricity consumption of various electric goods the label should enable consumers to purchase energy friendly products i e products with low energy consumption thereby making a significant contribution to the reduction of overall energy consumption this paper offers a systematic analysis of consumers interpretation of the energy label the results of a set of experimental studies revealed that consumers tend to base their estimates of a product s energy consumption mainly on the energy efficiency class e g a communicated on the energy label and largely ignore information about annual electricity consumption e g 120 kwh year thereby consumers potentially overestimate the energy friendliness of a product assigned a high energy efficiency rating this also holds true when consumers directly compare two products in terms of energy friendliness thus participants chose a higher consuming product because it had a high energy efficiency rating high energy efficiency ratings e g a can distort consumers perceptions of product categories that consume excessively e g freezers participants were seduced into thinking that a high energy efficiency rating e g a means the energy consumption of energy hogs is no longer problematic this paper provides evidence that the energy label could have a contrary effect than the one intended due to people s susceptibility to an energy efficiency fallacy this misinterpretation of the energy label could further explain why overall energy demand is increasing despite enhanced energy efficiency finally implications for policy makers and further research for enhancement of the energy label are discussed

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

separation of powers and political budget cycles political budget cycles pbcs arise when the electorate is imperfectly informed about the incumbent s competence and the incumbent has discretion over the budget focusing on the second condition we study how separation of powers affects pbcs in the composition of government spending we find that the details of the budget process namely the bargaining rules the status quo s location and the degree of compliance with the budget law are critical for the existence and the amplitudes of pbcs in particular when the status quo is determined by the previous budget and there is high compliance with the budget law separation of powers acts as a commitment device which solves the credibility problems that drive pbcs

productivity and efficiency change and shareholder value evidence from the spanish banking sector productivity change and shareholder value have been analysed in the banking sector in the last few years although it should be noted that these two important aspects have been studied separately in this regard the main contribution of our study is to link these two lines of research by verifying whether those banks characterized by higher levels of efficiency and productivity change have a higher shareholder value to measure changes in efficiency and productivity we use the malmquist nonparametric technique which is calculated from data envelopment analysis dea linear programming approach the malmquist total factor productivity index enables separation of the catching up effect i e changes over time in technical efficiency from technological change i e the shift of best practice frontier over time due to technological progress our results for a sample of listed spanish banks in the period 2000 to 2004 confirm that those banks with higher efficiency and productivity changes have a higher

developing food labelling strategies multi level labelling abstract labelling is an important cue for consumers as it helps to quickly communicate information about a product or production process however the majority of labels on the market are binary such as labels that indicate whether a product was produced using animal welfare friendly standards or not or whether it was produced organically or not yet there are many intermediate qualities that binary labels do not display in turn this could lead to a market failure a multi level label can show different process standards of products explicitly nonetheless before launching a multi level labelling system it should be tested if a multi level labelling system can shift market shares in favour of the labelled products using a consumer study with 1538 german consumers and the example of animal welfare the shares of product choices are calculated two comparisons of the shares of product choices will be made one between no label and a binary label and the other between no label and a multi level label the results suggest that a multi level labelling system achieves higher market shares therefore boosts sustainability attributes and can result in higher revenues or sales the results deliver important information for policymakers and industry

the role of environmental factors in growth accounting this paper explores a relatively new methodology the directional distance function method to analyse productivity growth the method allows us to explicitly evaluate the role that undesirable outputs of the economy such as carbon dioxide and other greenhouse gases have on the frontier production process which we specify as a piecewise linear and convex boundary function we decompose productivity growth into efficiency change catching up and technology change innovation we test the statistical significance of the estimates using recently developed bootstrap methods we also explore implications for growth of total factor productivity in the oecd and asian economies copyright 2004 john wiley sons ltd

legislative budget cycles recent literature suggests that electoral budget cycles are a phenomenon of new rather than established democracies what part of the democratization process explains the amelioration of the political budget cycle we argue the answer lies in part in the development of a strong party system we extend the classic rogoff siebert model to show that political budget cycles are possible in a legislative context with rational voters we then demonstrate that the development of a strong party system can restrain political budget cycles in a majoritarian electoral system finally we follow prior work in using vote share volatility as a measure of the institutionalization of the party system using newly collected vote share data for 433 elections for 90 democracies from 1980 2007 we calculate a measure of party institutionalization we then use this data to demonstrate that institutionalized party systems are associated with mitigated political budget cycles especially in majoritarian electoral systems

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

internalizing sustainable practices a configurational approach on sustainable forest management of the dutch wood trade and timber industry a number of environmental labels and certificates have been developed to inform consumers of the environmental impacts this paper explored different configurations of institutional and organizational conditions for the internalization of sustainable practices for the institutional conditions the level of institutional pressures were considered for the organizational conditions the following elements were taken into account 1 the timing of adoption 2 the willingness to cannibalize existing capabilities and routines to incorporate institutional demands for sustainability 3 the degree of implementation of these demands 4 the internal representation of environmental concerns and 5 the type of organization the paper analyzed sustainable forestry practices in wood trade and timber factories in the netherlands using a fuzzy set qualitative comparative analysis from the analysis three configurations were found 1 concerned internalization for early adopting wood trade companies 2 forced internalization for late adopting wood trade companies and 3 lagged internalization for late adopting timber factories the configurations revealed that important conditions for explaining internalization of sustainable practices are high levels of implementation and high levels of willingness to cannibalize the findings reaffirm the relevance of institutional and organizational conditions in explaining the internalization of environmental friendly practices they also showed that the interplay between a firm s internal and external environments influence the internalization of environmental practices the results imply that practice internalization is more subtle than previously understood in the literature

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

transparency political polarization and political budget cycles in oecd countries we investigate the effects of fiscal transparency and political polarization on the prevalence of electoral cycles in fiscal balance while some recent political economy literature on electoral cycles identifies such cycles mainly in weak and recent democracies in contrast we show conditioning on a new index of institutional fiscal transparency that electoral cycles in fiscal balance are a feature of many advanced industrialized economies using a sample of 19 oecd countries in the 1990s we identify a persistent pattern of electoral cycles in low er transparency countries while no such cycles can be observed in high er transparency countries furthermore we find in accordance with recent theory that electoral cycles are larger in politically more polarized countries

ossified materialism introduction to the special volume on absolute reductions in materials throughput and emissions drawing from papers in this special volume sv this introductory paper on absolute reductions argues that the magnitude scope and urgency of the sustainability challenge require a drastic change in global civilisation including a radical transformation of the institutional arrangements and socio technical systems that facilitate the pursuit of wellbeing the authors of this paper identify four main challenges to absolute reductions including the resource intensive conventional template for development macroeconomic structures and trade policies creating burden shifting and inequality a resourceefficiency improvements fallacy and the dominant consumerist culture and lifestyles the paper demonstrates

modelling technical efficiency in cross sectionally dependent stochastic frontier panels summary this paper proposes a unified framework for accommodating both time and cross sectional dependence in modelling technical efficiency in stochastic frontier models by combining the exogenously driven factor based approach and an endogenous threshold efficiency regime selection mechanism this approach is able to deal with both weak and strong cross sectional dependence in a flexible manner using a dataset of 26 oecd countries over 1970 2010 we provide satisfactory estimation results for the production technology parameters and the associated efficiency ranking of individual countries we find a positive spillover effect on efficiency supporting the hypothesis that knowledge spillover is more likely to be induced by technological proximity furthermore our approach enables us to identify efficiency clubs endogenously

electoral goals and center state transfers a theoretical model and empirical evidence from india we construct a model of redistributive politics where the central government is opportunistic and uses its discretion to make transfers to state governments on the basis of political considerations these considerations are the alignment between the incumbent parties at the central and state levels and whether a state is a swing state or not a testable prediction from the model is that a state that is both swing and aligned with the central government is especially likely to receive higher transfers we test this prediction using indian data for 14 states from 1974 75 to 1996 97 we find that a state which is both aligned and swing in the last state election is estimated to receive 16 higher transfers than a state which is unaligned and non swing

at a tipping point how the debate on biofuel standards sparks innovative ideas for the general future of standardisation and certification schemes abstract consumer demand for environmentally and socially responsible products is the driving force behind the expansion of competing certification systems paradoxically this has led to an increasingly crowded marketplace for labels and confusion among stakeholders such as producers retailers and buyers rather than providing clear and reliable product information as intended the situation has sparked a debate about the future of certification schemes and the need for a more streamlined system this article explores some of the innovative ideas coming from the current discussion regarding biofuel certification and standardisation and outlines how those ideas can be applied to create a global generic standard setting scheme for natural resources

biofuel developments in mozambique update and analysis of policy potential and reality abstract climate change rising oil prices and concerns about future energy supplies have contributed to a growing interest in using biomass for energy purposes several studies have highlighted the biophysical potential of biofuel production on the african continent and analysts see mozambique as one of the most promising african countries favorable growing conditions and the availability of land water and labor are mentioned as major drivers behind this potential moreover the potential of biofuel production to generate socio economic benefits is reflected in the government s policy objectives for the development of the sector such as reducing fuel import dependency and creating rural employment this article provides an overview of biofuel developments in mozambique and explores to what extent reality matches the suggested potential in the country we conclude that biofuel developments mainly take place in areas near good infrastructure processing and storage facilities where there is skilled labor available and access to services and goods moreover our analysis shows the need to timely harmonize current trends in biofuel developments with the government s policy objectives as the majority of existing and planned projects are not focusing on remote rural areas and in absence of domestic markets principally target external markets

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

environmental cost benefit analysis of alternative timing strategies in greenhouse gas abatement a data envelopment analysis approach assessing the benefits of climate policies is complicated due to ancillary benefits abatement of greenhouse gases also reduces local air pollution the timing of the abatement measures influences both the economic costs and ancillary benefits this paper conducts efficiency analysis of ten alternative timing strategies taking into account the ancillary benefits we apply the approach by kuosmanen and kortelainen valuing environmental factors in cost benefit analysis using data envelopment analysis ecological economics 62 2007 56 65 which does not require prior valuation of the environmental impacts the assessment is based on synthetic data from a dynamic applied general equilibrium model calibrated to the netherlands our assessment shows that if one is only interested in ghg abatement at the lowest economic cost then equal reduction of ghgs over time is preferred if society is willing to pay a premium for higher ancillary benefits an early mid intensive reduction strategy is optimal

valuing environmental factors in cost benefit analysis using data envelopment analysis abstract environmental cost benefit analysis ecba is used for the social evaluation of investment projects and policies that involve significant environmental impacts economic valuation of environmental impacts forms one of the critical steps of ecba we develop a new method for this purpose which does not require price estimation for environmental impacts using stated or revealed preference methods our approach is based on data envelopment analysis dea which is modified to ecba by using absolute shadow prices instead of relative prices we also discuss how the method can be used for sensitive analysis in ecba we illustrate the method by means of a hypothetical numerical example

opportunistic political cycles test in a young democracy setting this paper tests the theory of opportunistic cycles in a decade old democracy russia finds strong evidence of cycles and provides an explanation for why previous literature often found weaker evidence using regional monthly panel data we find that 1 the budget cycle is sizable and short lived public spending shifts toward direct monetary transfers to voters 2 the magnitude of the cycle decreases with democracy government transparency media freedom voter awareness and over time and 3 preelectoral manipulation increases incumbents chances for reelection the short length of the cycle explains underestimation of its size by previous literature because of low frequency data used in previous studies

non parametric frontier approach to modelling the relationships among population gdp energy consumption and co2 emissions abstract in this paper a non parametric approach based in data envelopment analysis dea is proposed as an alternative to the kaya identity a k a impact this frontier method identifies and extends existing best practices population and gdp are considered as input and output respectively both primary energy consumption and greenhouse gas ghg emissions are considered as undesirable outputs several linear programming models are formulated with different aims namely a determine efficiency levels b estimate maximum gdp compatible with given levels of population energy intensity and carbonization intensity and c estimate the minimum level of ghg emissions compatible with given levels of population gdp energy intensity or carbonization index the united states of america case is used as illustration of the proposed approach
