the renewables portfolio standard in texas an early assessment texas has rapidly emerged as one of the leading wind power markets in the united states this development can be largely traced to a well designed and carefully implemented renewables portfolio standard rps the rps is a new policy mechanism that has received increasing attention as an attractive approach to support renewable power generation though replacing existing renewable energy policies with an as of yet untested approach in the rps is risky early experience from texas suggests that an rps can effectively spur renewables development and encourage competition among renewable energy producers initial rps targets in texas were well exceeded by the end of 2001 with 915 mw of wind installed in that year alone rps compliance costs appear negligible with new wind projects reportedly contracted for well under 3 us cent k wh in part as a result of a 1 7 us cent kwh production tax credit an outstanding wind resource and an rps that is sizable enough to drive project economies of scale obliged retail suppliers have been willing to enter into long term contracts with renewable generators reducing important risks for both the developer and the retail supplier finally the country s first comprehensive renewable energy certificate program has been put into place to monitor and track rps compliance c 2002 published by elsevier science ltd less

prices in mixed cost allocation problems abstract we consider mixed cost allocation problems i e joint cost problems that involve two types of heterogeneous outputs divisible and indivisible the aumann shapley price mechanism is extended to this setting we also present a set of properties which characterize this cost sharing rule journal of economic literature classification numbers d63 c79

support systems for the diffusion of renewable energy technologies an investor perspective concern over climate change impacts and the projected depletion of fossil fuels has urged more governments to adopt policies that stimulate the diffusion of renewable energy technologies ret with an increasingly diverse suite of support instruments the question emerges as to which instruments or combinations are able to achieve faster more substantial diffusion results although various support instruments were extensively addressed in policy studies there is still no consensus this is partly because many policy studies take a policy maker approach in comparing support instruments leaving relationships between policy design and policy results as a black box this paper proposes an investor oriented perspective to analyze the diffusion potential of support systems for ret the main argument is that it is not the type of support instrument but rather its risk profitability characteristics that influence investor behavior and the rate of diffusion the two instruments most frequently discussed and compared are the feed in tariff and the quota model the analysis in this paper concludes that policy design is crucial while often feed in tariffs are applauded and quota system feared feed in tariffs may also bring about disappointing diffusion results when poorly designed while quota systems may be also conceived as attractive instruments for independent power producers

average cost pricing versus serial cost sharing an axiomatic comparison abstract a finite group of agents share a one output production function a cost sharing rule allocates the total cost among the users for every conceivable profile of output demands we investigate the space of possible cost sharing rules from an axiomatic perspective we provide two characterizations of average cost pricing one based on the axioms of additivity and monotonicity both with respect to the cost function and the other based on the axioms of additivity and a version of consistency we also provide a characterization of serial cost sharing based essentially on additivity and a free lunch axiom journal of economic literature classification numbers d63 d78 c79

one market one number a composite indicator assessment of eu internal market dynamics we consider the lack of consensus about an appropriate theoretical framework linking sub indicators as a defining characteristic of composite indicators this intrinsic feature implies uncertainties about the appropriate normalization and aggregation of the raw data the two are related index theory offers some valuable guidelines about their connection yet these do not fully solve the basic problem of expert disagreement we embed such residual disagreement in the aggregation method itself specifically we apply an impartial benefit of the doubt weighting procedure where weight restrictions incorporate the available information on experts opinions we apply this procedure to the dynamic performance assessment of eu internal market effects thereby highlighting its capacity to disaggregate member states observed performance shifts into changes relative to benchmarks and performance changes of the benchmarks i e catching up versus genuine progress our results indicate that the latter factor is more important in explaining the observed progress

cost competitive incentives for wind energy development in china institutional dynamics and policy changes abstract this paper presents an overview of the development of wind power in china the factors that affect the directions of wind power development are analyzed it examines the economics of windfarm development and compares it with conventional energy sources the major constraints in wind technology development and defects of the current policies are discussed it points out that wind power development should be subject to rational policy change and institutional adjustment it discusses the incentive mechanisms and institutional frameworks for future development particular importance is attributed to market incentives for wind power to reach the objectives of industrialization and commercialization a number of cost competitive incentive measures and policies are recommended i introducing market based mechanisms through standard power purchase agreement ii establishing effective investment policies and regulations to attract private investment iii promoting localization of wind turbine production iv adjusting tax and subsidy policies and v reforming governmental institutions to make clear rules and responsibilities for policymaking and enhancing communication coordination between relevant government agencies in order to formulate uniform and effective policies

waste performance of nuts 2 regions in the eu a conditional directional distance benefit of the doubt model abstract this paper attempts to benchmark the municipal solid waste msw management performance of the nuts 2 regions in the eu by constructing a composite indicator in order to account for commensurability weighting and aggregation issues of the performance indicators in regional waste and materials management this paper advocates a conditional directional distance version of the benefit of the doubt weighting technique in addition the waste management hierarchy defined by the eu is strongly embedded in the construction of our composite indicator the results reveal considerable differences in the aggregate performance of the regions even within member states in general waste sectors of the nuts 2 regions in austria belgium and germany generally do well in terms of msw management our results also reveal that some differences in the operating environment of the regions such as the number of tourist overnight stays are related to the aggregate performance of the regions however the observation that other conditions are not significantly related to the performance on a regional level is interesting as many policy makers frequently argue that the level of performance in their regions cannot be compared to that in other regions precisely due to this difference in operating conditions

government funded renewable energy innovation in china abstract with the rapid development of the economy china is facing pressures caused by traditional energy deficiency and environmental pollution in recent years which has forced the chinese government to start to pay attention to the development and utilization of renewable energy re this article based on data and statistics available up to 2008 studies features of china s re technology innovation and problems thereof it finds that national science and technology programs are the main aspect of china s re technology innovation and most of r d funds for the re technology come from china s three main national programs besides the overall expenditures on re technology innovation constitute only a small proportion of china s total domestic r d funding and seem not enough this paper also finds that compared with research and development stages of re technology the demonstration and diffusion of re technology in china are given less attention and thus are relatively less sufficient furthermore influenced by china s traditional scientific research system there appears lack of sufficient incentives and opportunities for private sectors to fully participate in re technology innovation because most national programs are undertaken by universities or research institutes

prospects for global market expansion of china s wind turbine manufacturing industry abstract emerging economies are increasingly contributing to global innovation including clean tech innovation the development of china s wind power sector has often been used to illustrate this point china s domestic wind power market is the largest in the world and is largely supplied by domestic manufacturers competition for market share in the domestic market may pressure firms to innovate which consecutively improves prospects for global expansion this paper reviews developments in china s domestic wind turbine market using the technological innovation system framework we analyze the pressure to innovate arising from market competition and assess the prospects for global expansion of chinese wind turbine manufacturers we conclude that domestic customers are not pressured or incentivized to perform with respect to power output such that turbine manufacturers are not pressured to perform with respect to turbine efficiency or maintenance needs pressure to innovate is further reduced by formalizing connections between wind farm developers and turbine manufacturers chinese turbine manufacturers cannot yet compete with leading global brands in technological leadership the prospects for exports are improved however by the preferential supply of project financing from institutional investors such as the china development bank from chinese utilities that seek global expansion and from the manufacturers themselves

an efficient and almost budget balanced cost sharing method for a convex technology c we characterize cost sharing games where the nash equilibrium demands maximize total surplus budget balance is possible if and only if c is polynomial of degree n 1 or less for general c the residual cost shares are balanced if at least one demand is null a characteristic property if the cost function is totally monotone a null demand receives cash and total payments may exceed actual cost the ratio of excess payment to efficient surplus is at most min 2logn 1 for power cost functions c a ap p 1 the ratio of budget imbalance to efficient surplus vanishes as 1np 1 for analytic cost functions the ratio converges to zero exponentially along a given sequence of users all asymptotic properties are lost if the cost function is not smooth

multi product serial cost sharing an incompatibility with the additivity axiom previous literature has shown that the serial cost sharing rule is endowed with a variety of desirable incentive and equity features by definition applications of this mechanism are essentially constrained to single service facilities we investigate difficulties that emerge when attempting to extend serial cost sharing to multi product environments in particular we show that such an extension is incompatible with the additivity axiom journal of economic literatureclassification numbers d63 c71

loss allocation in energy transmission networks abstract in this paper we study a cost allocation problem that is inherent to most energy networks the allocation of losses in particular we study how to allocate gas losses between haulers in gas transmission networks we discuss four allocation rules two of them have already been in place in real networks and two others that are defined for the first time in this paper we then present a comparative analysis of the different rules by studying their behavior with respect to a set of principles set forth by the european union this analysis also includes axiomatic characterizations of two of the rules finally as an illustration we apply them to the spanish gas transmission network

a malmquist based approach to change in local economic well being murias p novello s and martinez roget f a malmquist based approach to change in local economic well being regional studies the focus on the multifaceted nature of well being has increased substantially in recent years this paper employs data envelopment analysis dea combined with the malmquist index to examine the temporal change in the economic well being of spanish provinces over the ten year period between 1996 and 2006 this method not only allows the aggregation of multiple indicators and the estimation of well being shifts over time but also shows the sources of variation in local economic well being the results seem to suggest that whilst economic well being has improved in the great majority of provinces this advancement stems largely from a more favourable environment than from the specific capacity of each province to reduce its relative distance from key benchmarks

how to decide when experts disagree uncertainty based choice rules in environmental policy environmental economists have traditionally addressed the issue of choice under uncertainty by applying the expected utility hypothesis when policymakers face a panel of experts with widely divergent beliefs the problem may more accurately be described as a case of choice under pure uncertainty arrow and hurwicz 1972 demonstrate that rational choice criteria under pure uncertainty will focus on the extremes of the state space not the midpoint as is typically assumed using nordhaus s dice model uncertainty based choices about global warming policies are evaluated linkages to the safe minimum standard and the precautionary principle are also discussed

a review on global wind energy policy with the increasing negative effects of fossil fuel combustion on the environment in addition to limited stock of fossil fuel have forced many countries to inquire into and change to environmentally friendly alternatives that are renewable to sustain the increasing energy demand energy policy plays a vital role to mitigate the impacts of global warming and crisis of energy availability this paper explores the wind energy industry from the point of view of the wind energy policy it is noticed that energy policy could help increasing wind power generation as well as stimulating the energy industry it may be stated that without specific energy policy a country would not be able to solve the acute problems like reducing greenhouse gases ghgs emission scarcity of energy etc this paper discussed the existing successful energy policies for few selected countries based on literatures it has been found that fit rps incentives pricing law and quota system are the most useful energy policies practiced by many countries around the world then status of wind energy policy for malaysia was investigated and compared with few selected countries around the world

erratum to environmental determinants of cost sharing multiple cost sharing rules often coexist in seemingly identical environments we use shared irrigation costs as a context for examining the extent to which the structural environment explains cost sharing rule selection we find that environmental factors affecting irrigation costs and benefits as well as those determining irrigator distribution along the ditch have impressive explanatory power these results present some of the first formal empirical analysis of the manner in which structural features influence the actual cost sharing choices of economic agents moreover our results also suggest that previous axiomatic studies are reflective of real world cost sharing behavior

on demand responsiveness in additive cost sharing under partial responsibility the ranking of cost shares should never contradict that of demands the solidarity axiom says that if agent i demands more j should not pay more if k pays less it characterizes the quasi proportional methods sharing cost in proportion to rescaled demands full responsibility rules out cross subsidization for additively separable costs restricting solidarity to submodular cost characterizes the fixed flow methods containing the shapley shubik and serial methods the quasi proportional methods meet but most fixed flow methods fail group monotonicity if a group of agents increase their demands not all of them pay less serial cost sharing is an exception

bargaining with an agenda gradual bargaining is represented by an agenda a family of increasing sets of joint utilities parameterized by time a solution for gradual bargaining specifies an agreement at each time we axiomatize an ordinal solution i e one that is covariant with order preserving transformations of utility it can be viewed as the limit of step by step bargaining in which the agreement of the last negotiation becomes the disagreement point for the next the stepwise agreements may follow the nash solution the kalai smorodinsky solution or many others and still yield the ordinal solution in the limit

beyond gdp an overview of measurement issues in redefining wealth in the last decades a growing quantity of literature has been written about concepts such as quality of life and well being as a proxy for evaluating societal prosperity and progress this paper analyses the theoretical foundations and the empirical validity of multi dimensional technical tools that can be used for well being measurement there is no doubt that there is a lot of complexity and fuzziness inherent in multi dimensional concepts such as well being a possible reduction of this complexity a pre condition for policy making introduces the problem of the descriptors used indicators and indexes in a multi dimensional framework multi criteria evaluation is a consistent approach for the construction of so called composite indicators often some individual indicators improve while others deteriorate this is the classical conflictual situation dealt with in multi criteria evaluation in particular non compensatory methods are quite relevant since compensability implies complete substitutability between different types of capital uncertainty and sensitivity analysis can estimate the robustness of the results obtained and help the framing of the debate around the conceptual framework used that is which representation of reality and thus which societal values and interests has been considered

the development of renewable energy power in india which policies have been effective abstract the international energy agency has identified the development of renewable energy sources as a key element to mitigate climate change at the same time it has projected india to be the second largest contributor to the increase in global energy demand to 2035 india hence faces a significant challenge to ensure its energy security by diversifying its power generation mix in the wake of the creation of a green climate fund in cancun this paper studies empirically the effect of the introduction of the electricity act 2003 and the tariff policy 2006 as well as the implementation of feed in tariffs and minimum quotas on clean electricity sourcing on the development of grid connected renewable energy power in nine indian states over the period 2001 2009 results suggest that the passing of the tariff policy 2006 state level policies quantity based instruments and a greater participation of the private sector have played a key role in promoting the development of installed capacity from renewable energy power in the nine states of the sample

an alternative approach to monetary aggregation in dea this paper proposes a set of alternative dea based money indices that are proved to be both theoretically and empirically competing monetary aggregates since they perform as good as the divisia aggregates based on all the results concerning causality forecasting and money demand we conclude that dea money aggregates prove to be at least competing alternatives to the divisia aggregates and hence suggest that these new aggregates may be considered along with the existing weighted monetary aggregates like the divisia ones given the inherent benefit of the doubt weighting mechanism underlying the dea models where the optimal weight assigned by dea to each monetary asset reflects the ongoing financial innovation and the reserve bank of india s policy priority in the distribution of total liquidity we feel that the dea money indices can truly capture the liquidity better with ongoing financial innovations in the economy

technological change technological catch up and capital deepening relative contributions to growth and convergence we decompose labor productivity growth into components attributable to 1 technological change shifts in the world production frontier 2 technological catch up movements toward or away from the frontier and 3 capital accumulation movement along the frontier the world production frontier is constructed using deterministic methods requiring no specification of functional form for the technology nor any assumption about market structure or the absence of market imperfections we analyze the evolution of the cross country distribution of labor productivity in terms of the tripartite decomposition finding that technological change is decidedly nonneutral and that both growth and bipolar international divergence are driven primarily by capital deepening jel o30 o47 d24

ordinal cost sharing abstract we ask how the best known mechanisms for solving cost sharing problems with homogeneous cost functions the value proportional and serial mechanisms should be extended to arbitrary problems we propose the ordinality axiom which requires that cost shares should be invariant under essentially all increasing transformations of the measuring scales following thevalueapproach first we present an axiomatization of the shapley shubik rule based on ordinality next we define and axiomatize two extensions of theserialmechanism which contrary to the friedman moulin rule are ordinal finally we note that the aumann shapley extension of theproportionalmechanism is not ordinal we propose and defend an alternative proportional extension which does satisfy ordinality journal of economic literatureclassification numbers d63 c71

feed in tariff mechanisms for large scale wind power in china abstract in recent years with the large scale and centralized development of the wind power industry in china wind power curtailment has become increasingly serious in order to promote wind power consumption in china this paper designs four kinds of feed in tariff fit mechanisms a double track fit mechanism based on a ratio a time of use benchmarking tariff mechanism a net back pricing mechanism based on the inter provincial wind power consumption market and an fit mechanism based on negotiation then we establish a benefit distribution model to analyze the wind power stakeholders benefits finally based on the four kinds of fit mechanisms and the benefit distribution model we propose the best fit mechanisms for the various electricity market circumstances in china in order to provide a reference to formulate wind fit to promote the consumption of wind power and to advance the sustainable development of renewable energy in developing countries

human development revisited a new undp report abstract the undp s first annual human development report is reviewed and discussed the report introduces a new index the human development index hdi as a counter to measures of national income such as gdp measuring development of countries with the aid of this index gives a significantly different ordering to one based on gnp per capita this point is not disputed although success on the index is not a necessary and sufficient condition for success in terms of rapid economic growth as is shown by the case of sri lanka nevertheless the report is welcome for its attention to human development issues for its useful statistical annex and for its observation that the poverty of the people of the developing world has been no barrier to the affluence of their armies

policies to accelerate the growth of offshore wind energy sector in india abstract india s power generation capacity needs to be augmented to support the growing demands for electricity india which has predominantly used fossil fuels to power its generators need to make a switch to clean energy fuels but renewable sources form a miniscule portion 26 gw 12 of india s overall installed power capacity 210 gw there is no contribution from offshore wind farms to the energy basket for india as there is no policy framework to encourage the development of offshore wind farms several european countries have tapped the offshore wind energy potential to reduce their dependence on adopted by these countries to identify the core components 21 of them of robust policy intervention a detailed questionnaire was administered to 181 stakeholders of wind energy in india to seek their feedback on these building blocks these core components variables in research parlance are then subjected to factor analysis to understand the underlying structure of the variables the factor analysis logically reduces these 21 variables into five factors government support fiscal and quota based incentives availability of local expertise capital for investments and building an enabling r d ecosystem which are then fed into a logistic regression model as independent variables to predict the probability of growth of offshore wind energy dependent variable in the country the logistic regression model gives the weight the impact of these independent variables in influencing the growth of offshore wind energy in india it emerges that government support fiscal and quota based incentives and building an enabling r d ecosystem have a much higher impact on the growth of offshore wind energy for india this paper fills the gap of absence of an empirically tested framework on offshore wind energy policy for india

envisaging feed in tariffs for solar photovoltaic electricity european lessons for canada abstract while it is widely agreed that support schemes need to be put in place to promote the use of renewable electricity there is less consensus as to what are the best kinds of strategies to use what is attracting increasing attention in canada is a system of renewable portfolio standards in this all power suppliers are under an obligation to ensure that a certain percentage of the electricity they generate is from renewable resources they can either generate that electricity themselves or purchase green certificates from those who have used renewables to generate electricity recent experience from europe however suggests that a whole hearted commitment to this single strategy could be premature and potentially damaging for the development of all kinds of renewable electricity in canada solar photovoltaics included on the other side of the atlantic ocean the use of so called feed in tariffs that is an obligation for utilities to purchase at a set price the electricity generated by any renewable energy resource is widely credited with accelerating the development of renewable electricity in many countries the purpose of this article is to reflect upon this european experience with feed in tariffs to stimulate discussions regarding what promise they might hold for the development of solar photovoltaic electricity in canada the article is divided into three main sections in the first section policies to promote renewable electricity presently in place in different parts of canada are reviewed attention is then focused more specifically in the second section of this article upon feed in tariffs after defining and describing this alternative system experiences in the countries of the european union are reviewed the main strengths and weaknesses of feed in tariffs in the european experience are also examined the focus then moves back to canada in the third section of the article in this a system of feed in tariffs is proposed for the province of ontario in order to provide just one example of the kind of support that could be forthcoming

wind farm investment risks under uncertain cdm benefit in china abstract china has set an ambitious target to increase its wind power capacity by 35 gw from 2007 to 2020 the country s hunger for clean power provides great opportunities for wind energy investors however risks from china s uncertain electricity market regulation and an uncertain energy policy framework mainly due to uncertain clean development mechanism cdm benefits prevent foreign investors from investing in china s wind energy the objectives of this paper are to 1 quantify wind energy investment risk premiums in an uncertain international energy policy context and 2 evaluate the impact of uncertain cdm benefits on the net present values of wind power projects with four scenarios this study simulates possible prices of certified emissions reductions cers from wind power projects project net present values npvs have been calculated the project risk premiums are drawn from different and uncertain cer prices our key findings show that uncertain cdm benefits will significantly affect the project npvs this paper concludes that the chinese government needs revising its tariff incentives most likely by introducing fixed feed in tariffs fits and re examining its cdm granting policy and its wind project tax rates to facilitate wind power development and enable china to achieve its wind energy target

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

the determination of marginal cost prices under a set of axioms the main purpose of this paper is to provide an axiomatic approach to marginal cost mc pricing and to point out its similarity with aumann shapley a s pricing the latter is a cost sharing price mechanism discussed in 3 and 6 that is derived from a set of five natural axioms in this paper we consider models in which there is one producer with a given technology who faces fixed input prices and produces a finite number of consumption goods thus we can uniquely derive the cost function that describes the minimal cost of producing a given vector of consumption goods by a price mechanism p we mean a rule or a function that associates with each cost function f and vector a of quantities a vector of prices

addressing india s energy security and options for decreasing energy dependency abstract energy plays the most vital role in the economic growth and security of any nation future economic growth crucially depends on the long term availability of energy from sources that are affordable accessible and environmental friendly acute energy scarcity in india in recent years is hampering its industrial growth and economic progress india is strongly dependent on the fossil fuels for its energy requirements which are also contributing significantly to greenhouse gases emissions it is proposed that the introduction of renewable energy sources portfolio to the future energy mix and diversification of fuel sources will i enhances energy security and mitigates co 2 emission and ii improves the quality of life if india failed to protect its environment not only its economic growth would be impeded but also would pose serious health hazards

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

fostering a renewable energy technology industry an international comparison of wind industry policy support mechanisms this article examines the importance of national and sub national policies in supporting the development of successful global wind turbine manufacturing companies we explore the motivations behind establishing a local wind power industry and the paths that different countries have taken to develop indigenous large wind turbine manufacturing industries within their borders this is done through a cross country comparison of the policy support mechanisms that have been employed to directly and indirectly promote wind technology manufacturing in 12 countries we find that in many instances there is a clear relationship between a manufacturer s success in its home country market and its eventual success in the global wind power market whether new wind turbine manufacturing entrants are able to succeed will likely depend in part on the utilization of their turbines in their own domestic market which in turn will be influenced by the annual size and stability of that market consequently policies that support a sizable stable market for wind power in conjunction with policies that specifically provide incentives for wind power technology to be manufactured locally are most likely to result in the establishment of an internationally competitive wind industry

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

rickety numbers volatility of university rankings and policy implications abstract the most popular world university rankings are routinely taken at face value by media and social actors while these rankings are politically influential they are sensitive to both the conceptual framework the set of indicators and the modelling choices made in their construction e g weighting or type of aggregation a robustness analysis based on a multi modelling approach aims to test the validity of the inference about the rankings produced in the academic ranking of world universities arwu of shanghai jiao tong university and those produced by the uk s times higher education supplement thes conclusions are drawn on the reliability of individual university ranks and on relative country or macro regional performance e g europe versus usa versus china in terms of the number of top performing institutions we find that while university and country level statistical inferences are unsound the inference on macro regions is more robust the paper also aims to propose an alternative ranking which is more dependant on the framework than on the methodological choices

responsibility and cross subsidization in cost sharing we propose two cost sharing theories in which agents demand comparable commodities and are responsible for their own demand under partial responsibility agents are not responsible for the asymmetries of the cost function two agents consuming the same quantity pay the same price this holds under full responsibility only if the cost function is symmetric if the cost function is additively separable each agent pays her stand alone cost under full responsibility this holds under partial responsibility only if the cost function is also symmetric we generalize moulin and shenker s distributivity axiom to cost sharing methods for heterogeneous goods moulin h shenker s 1999 distributive and additive costsharing of an homogeneous good games econ behav 27 299 330 the subsidy free serial method moulin h 1995 on additive methods to share joint costs japan econ rev 46 303 332 is essentially the only distributive method meeting ranking and dummy the cross subsidizing serial method sprumont y 1998 ordinal cost sharing j econ theory 81 126 162 is the only distributive method satisfying separability and strong ranking we propose an alternative characterization of the latter method based on a strengthening of distributivity

profit sharing in unique nash equilibrium characterization in the two agent case abstract two agents jointly operate a decreasing marginal returns technology to produce a private good we characterize the class of output sharing rules for which the labor supply game has a unique nash equilibrium it consists of two families rules of the serial type which protect a small user from the negative externality imposed by a large user and rules of the reverse serial type where one agent effectively employs the other agent s labor exactly two rules satisfy symmetry a result in sharp contrast with moulin and shenker s characterization of their serial mechanism as the unique cost sharing rule satisfying the same incentives property moulin h shenker s 1992 serial cost sharing econometrica 60 5 1009 1037 we also show that the familiar stand alone test characterizes the class of fixed path methods under our incentives criterion friedman e j 2004 strong monotonicity in surplus sharing econ theory 23 643 658

asymmetric cost sharing mechanisms we describe the construction and analysis of asymmetric cost sharing mechanisms in which a variety of axioms are applied to subsets of the agents goods we show that the analysis can be quite subtle as apparently similar axiomatizations lead to significantly different results in particular combinations of symmetric mechanisms can be extremely asymmetric and biased in addition we characterize some interesting mixed mechanisms

on the discrete version of the aumann shapley cost sharing method each agent in a finite set requests an integer quantity of an idiosyncratic good the resulting total cost must be shared among the participating agents the aumann shapley prices are given by the shapley value of the game where each unit of each good is regarded as a distinct player the aumann shapley cost sharing method charges to an agent the sum of the prices attached to the units she consumes we show that this method is characterized by the two standard axioms of additivity and dummy and the property of no merging or splitting agents never find it profitable to split or to merge their consumptions we offer a variant of this result using the no reshuffling condition the total cost share paid by a group of agents who consume perfectly substitutable goods depends only on their aggregate consumption we extend this characterization to the case where agents are allowed to consume bundles of goods
