the evolution of hyperbolic discounting implications for truly social valuation of the future abstract we explore the standard expected utility model and alternatives to it we then examine the behavioral and neurological evidence for hyperbolic discounting we discuss evidence related to the neurological and behavioral evolution of discounting in non human animals and in humans we explore new findings about the importance of sociality in human behavior and the implications for truly social time preference finally we discuss the implications of the neurological evidence on discounting for social environmental valuation in particular the implications for very long run decisions such as those involved in climate change mitigation and biodiversity preservation

a test of the theory of reference dependent preferences eight alternative methods of eliciting preferences between money and a consumption good are identified two of these are standard willingness to accept and willingness to pay measures these methods differ with respect to the reference point used and the dimension in which responses are expressed the loss aversion hypothesis of tversky and kahneman s theory of reference dependent preferences predicts systematic differences between the preferences elicited by these methods these predictions are tested by eliciting individuals preferences for two private consumption goods the experimental design is incentive compatible and controls for income and substitution effects the theory s predictions are broadly confirmed

willingness to pay attitudes and fundamental values on the cognitive context of public preferences for diversity in agricultural landscapes abstract our study set out to investigate if and how willingness to pay both hypothetical and actual might reflect individuals wider cognitive networks we draw on the idea of cognitive hierarchies i e the notion that concrete preferences and attitudes are embedded in networks of more abstract beliefs and values and explore if willingness to pay wtp as expressed through contingent valuation can be understood as part of such hierarchies to this end we elicited stated and actual wtp in a survey of public preferences and attitudes towards the establishment of an agri environmental payment scheme in northeim germany that rewards farmers for the provision of riparian buffer strips two main findings emerged from the study first only a very small proportion of those stating positive wtp did actually transfer the money second contrary to our hypotheses results from a structural equation model suggest that stated wtp was only poorly connected to attitudes towards the payment scheme and other potentially relevant more abstract beliefs and values this casts doubts on the meaningfulness of such statements of the ten different fundamental value types included only universalism and conformity played a significant role in the cognitive hierarchy and informed generalised environmental beliefs as well as attitudes towards the payment scheme as attitudes seemed to be better integrated in the cognitive network than wtp we discuss if surveys of public preferences should rely on attitude statements rather than solely on monetary values

in defense of health based standards abstract this paper explores the utilitarian ethical foundations underlying two standards for pollution control an efficiency standard and a health based standard the main point is that a health based standard can be defended quite easily on utilitarian grounds safety proponents need not be self serving irrational nor ignorant criticism of health based standards as too costly is not always persuasive since material consumption is not the only component of social welfare nor do consumption increases necessarily increase social welfare

the worth of a wildflower precautionary perspectives on the environmental risk of gmos abstract how much is a wildflower worth inspired by the worth of a songbird by funtowicz and ravetz funtowicz s o ravetz j r 1994 the worth of a songbird ecological economics as a post normal science ecological economics 10 197 207 we use the value of a wildflower as symbol of the complexity of evaluating environmental qualities and risks we critically discuss the application of cost benefit analysis in evaluating environmental impacts of adoption of genetically modified organisms gmos we argue that cost benefit analysis should be supplemented with other methods such as processes for assessing uncertainty accommodation of scientific disagreements and integration of stakeholders interests and perspectives a more inclusive perspective is to develop precautionary approaches that recognize the multidimensional nature of environmental qualities and risks such as irreplaceability irreversibility uncertainty and complexity precautionary approaches can contribute to develop a stronger environmental responsibility within the framework of rational self interest

common property equality and development the appeal of common property ideas may be traced in large measure to the fact that they seem to embody widely held values of equality on the other hand empirical examination of common property institutions reveals that they can coexist with significant inequality in this paper the relationship between common property and equality is examined it is argued that the role of common property can only be understood in the context of the associated private property institutions common property in agriculture is interpreted as part of a system based on small scale peasant proprietorship of arable land common property institutions provide a method of capturing scale economies and thereby increasing the efficiency of small scale proprietorship in competition with large scale production based on wage labor

the assumption of equal marginal utility of income how much does it matter abstract in most applied cost benefit analyses individual willingness to pay wtp is aggregated without using explicit welfare weights this can be justified by postulating a utilitarian social welfare function along with the assumption of equal marginal utility of income for all individuals however since marginal utility is a cardinal concept there is no generally accepted way to verify the plausibility of this latter assumption nor its empirical importance in this paper we use data from seven contingent valuation studies to illustrate that if one instead assumes equal marginal utility of the public good for all individuals aggregate monetary benefit estimates change dramatically

the ideology of efficiency searching for a theory of policy analysis the potential pareto improvement criterion and other measures of economic efficiency do not pass the test of consistency and coherence within economic theory nor do such measures accord with what public decision makers seek in policy advice from economists such efficiency measures are nonetheless durable components of the ideology of economics in general and benefit cost analysis in particular the objectivity of the policy scientist has been confused with the objectivity of the science while economic efficiency has no claim to objectivity the policy scientist can be an objective analyst of policy choices

sustainable development looking for new strategies abstract many strategies have been proposed to reach sustainable development a great many of these strategies aim at one type of problem preventing environmental deterioration while ignoring the importance of economic or social goals in addition while political decisions are at the heart of the choices to be made most researchers seem to consider sustainable development as a mere technical problem in this paper we describe a more complete strategy for sustainable development we use the outlines of this strategy to find out what knowledge and skills are still needed the strategy is based on the idea that it is necessary to find consensus on the development of a socio environmental system as a whole and between all people involved it leaves us with at least two main areas that need further study the supply of information and the management of consensus building a formal procedure for consensus building might be developed based on the literature and on experiences with environmental impact assessments special attention is paid to the information needed it can be summarized as information about 1 delimiting a socio environmental system 2 the needs and wants to be satisfied via that system and 3 the physical ecological economic social and cultural constraints of satisfying those needs and wants

discounting according to output type federal discount rate policies advocate both a high rate representing the marginal productivity of capital and a low rate representing the government borrowing rate these differential discount rate policies could be inconsistent and biased in favor of projects on which the lower discount rate is applied this paper shows that the coexistence of different discount rates may be appropriate depending on the type of project output when a project s outputs are perfect substitutes for private consumption both its costs and benefits should be discounted using the marginal productivity of capital however if the project s outputs are separable in the utility function the benefits should be discounted using the net of tax rate of return

choices without prices without apologies valuing is usually regarded as a process of compressing information about attributes into a single metric armed with this reduced form of compact information the consumer can consider a particular object with a particular price attached or implied and make an informed decision but the process of valuing is less straightforward than we ordinarily suppose when environmental goods and services become the object of information compaction it is possible that important information is lost we comment on the choice problem germane to environmental goods and services and challenge the presumption that environmental choices made without explicit pricing are inferior to those in which hypothetical valuation studies are undertaken

toward a more complete model of individual transferable fishing quotas implications of incorporating the processing sector abstract economic analyses of individual transferable quota itq fisheries management traditionally have focused on the harvesting sector however harvester decisions impact the economic performance of co dependent processing firms this paper incorporates both sectors in an analysis of the effect of itqs on commercial fisheries results show that as a consequence of season elongation under a harvester only allocation of fishing rights capital nonmalleability implies that processor quasi rents will be redistributed to harvesters these losses could promote political gridlock and jeopardize adoption of an itq policy unless they are fully compensated or unless redistribution is avoided by a policy superior initial allocation of rights to both harvesters and processors

the approach of ecological economics this paper discusses the major tenets of ecological economics including value pluralism methodological pluralism and multi criteria policy assessment ecological economics offers viable alternatives to the theoretical foundations and policy recommendations of neoclassical welfare economics a revolution in neoclassical economics is currently taking place and the core assumptions of welfare economics are being replaced with more realistic models of consumer and firm behaviour this paper argues that these new theoretical and empirical findings are largely ignored in applied work and policy applications in environmental economics as the only heterodox school of economics focusing on the human economy both as a social system and as one imbedded in the biophysical universe and thus both holistic and scientifically based ecological economics is poised to play a leading role in recasting the scope and method of economic science

public funding of environmental amenities contingent choices using new taxes or existing revenues for coastal land conservation alternative funding approaches affect stated preferences an individual s willingness to reallocate existing tax dollars exceeds willingness to pay new taxes to conserve land however stated preferences also imply a non zero opportunity cost to existing tax dollars different income groups reveal statistically equivalent marginal utilities both for income and for reallocating tax dollars yet individuals with lower income show a relatively larger increase in their willingness to support land conservation when the choice shifts from new taxes to reallocation of existing tax dollars the paper encourages consideration of equity implications that may be obscured when analysts focus on willingness to pay

environmental and ecological economics a citation analysis this study looks at two distinct questions dwhat have been the most influential journal articles in environmental economics and ecological economics over the 10 year period 1994 2003 t and dhow much overlap is there between the fields of environmental and ecological economics t we examine the references in all articles published in jeem and ecological economics ee over this period for each of these two fields a list of the top articles and top journals cited by articles published in jeem and ee is presented we also present some results based on our study of the isi journal citation reports we find that there is a significant overlap between the two fields at the journal level the two journals cite similar journals there is a correlation of 0 34 between the number of citations received by the journals that are most cited and the correlation is even higher if journal self citation is excluded the main differences are that ecological economics tends to cite but not be cited by general natural science journals more often than environmental economics does environmental economics cites more heavily from journals rather than other publications and citations in environmental economics are more concentrated on particular journals and individual publications however there is much less similarity at the level of individual articles nonmarket valuation articles dominate the most cited articles in jeem while green accounting sustainability and the environmental kuznets curve are all prominent topics in ee d 2005 elsevier b v all rights reserved

evolutionary policies for sustainable development adaptive flexibility and risk minimising abstract an evolutionary perspective on policies to foster sustainable development is presented it is argued that policies suggested by the traditional economic theory of environmental policy can stimulate unsustainable socio economic structures and patterns in addition they are unable to remove undesired locked in systems and technologies drawing on evolutionary thinking characterised by diversity selection innovation path dependence and bounded rationality an alternative partly complementary theory of environmental policy is suggested specific attention is given to the role of strategies that are aimed at increasing diversity and adaptive flexibility and at reducing risk

justifying precautionary policies incommensurability and uncertainty abstract when decisions are taken in conditions of keynesian or knightian uncertainty and when there is a threat of serious or irreversible environmental damage the precautionary principle is often recommended to guide decision making however the precautionary principle has been widely criticised in response to these criticisms a qualitative version of the precautionary principle is developed which draws its normative content from a blend of formal decision theory and political philosophy it is argued that precautionary action can be justified by some flexible combination of uncertainty and incommensurability the greater the uncertainty the less incommensurability is required to justify precautionary action and vice versa throughout the paper the arguments are explored using the example of climate change decision problems

price elasticity in import demand equations considering product quality estimates for the brazilian economy 1996 2013 abstract recent empirical studies argue that traditional trade models ignore product quality usually leading to bias in price elasticities which prevents the correct evaluation of trade determinants and the development of trade policies this article quantifies the effect of quality on brazilian imports for that we estimate import demand equations including a proxy for the quality of imported goods according to pooled data panel results show that price affects the demand for brazilian imports more than quality unlike literature results in developed countries introducing the quality proxy increased the price coefficient this occurred more significantly in estimates for the manufacturing sector supporting the hypothesis of elasticities bias when estimation does not consider product differentiation

distributional weights in cost benefit analysis should we forget about them many argue that it is socially inefficient to use distributional weights in cost benefit analysis and that doing so implies large inefficiency losses when distributional matters can be dealt with trough income taxation instead our results question this view by showing a large range of cases when distributional weights are second best optimal to use one example is when different provided goods affect tax revenues equally per dollar spent utility functions that are separable in the provided goods is sufficient for this most results hold for linear and non linear income taxes and whether they are optimal or not general policy implications are discussed

the neoclassical trojan horse of steady state economics the vision of a steady state economy elaborated by herman daly describes an economy that uses materials and energy within the regenerative and assimilative limits of the planet s ecosystems sustainable scale just distribution and efficient allocation are its constitutive theoretical goals this paper is a critique of the theoretical foundations of steady state economics it argues that steady state economics consists in an attempt to squeeze neoclassical economics into a biophysical and ethical corset as a result many fundamental flaws and criticisms of neoclassical economics remain as a consequence steady state economics does not lead to a radical departure from or improvement upon neoclassical theory but rather to fundamental internal inconsistencies between the old economics paradigm and new progressive ecological economic thinking contradictions appear at various levels ranging from ontology and methodology to theory and values as daly has pioneered the foundations of ecological economics with his thinking these ambiguities are not only problematic for steady state economics but ecological economics as a field more generally the paper concludes that ecological economics has to let go of neoclassical foundations as they contradict its core values and ambitions a new and consistent theory of political economy of the environment along heterodox lines is needed

sustainability and the intergenerational distribution of natural resource entitlements abstract the paper describes an olg economy with a single exhaustible resource that has amenity value the steady states of this economy form a continuum implying path dependency we compare three policy scenarios first a zero extraction policy of enforced conservation that avoids environmental degradation possibly at the expense of intertemporal efficiency second a grandfathering policy that endows the present generations with all resources and that ensures efficiency but cannot prevent a persistent decline in lifetime utility from one generation to the next third a trust fund policy where future generations receive claims for the natural resource of the three only the trust fund ensures efficiency and protects welfare of all generations

project evaluation with democratic decision making what does cost benefit analysis really measure abstract it is often argued that projects involving public good changes should be chosen on the basis of monetary valuation and cost benefit analysis cba however cba is not value free when used to measure welfare it is based on highly controversial value judgements when used to measure efficiency it is based on assumptions of limited relevance to democratic decision making processes cba measures total net willingness to pay neither more nor less while interesting in its own right the normative significance of this indicator is not obvious

complementarities momentum and the evolution of modern manufacturing in the nineteenth century the railroad and telegraph were at the center of a set of technological advances physical investments and managerial innovations that transformed american industry alfred chandler 1977 later the automobile and telephone played a similar role in another transformation today the high tech industries include computers telecommunications and electronics working on our remarkably powerful computers even as they rapidly become obsolete co authoring papers by electronic mail and fax and conversing on our portable cellular telephones we are struck by what appears to be a self supporting and reinforcing dynamic to the technological improvements across the electronics industries an advance almost anywhere in the sector seems to call forth more advances across the sector these advances are occurring contemporaneously with a broad pattern of other changes not only in the electronics industries but in manufacturing more generally and not just in hardware but in methods and organization as well a new paradigm has begun to emerge in contrast to traditional manufacturing firms modern firms frequently 1 make greater use of flexible programmable equipment and of computeraided design and manufacturing technologies 2 have fewer job classifications 3 offer more varieties of their major products and or update their product lines more frequently 4 put more emphasis on speed in order processing production and delivery 5 hold much lower inventories of intermediate and finished goods 6 rely on subcontractors to supply a greater proportion of the total value added and 7 overlap design product and process engineering to speed the introduction of new products these features of modern manufacturing firms encompass technology choices marketing strategies personnel policies supplier relations lines of internal communications and other operational policies in a far reaching and coherent pattern whose existence in the words of michael piore 1986 poses a challenge to economic theory in a recent paper milgrom and roberts 1990 proposed a theory to explain the emergence of this new paradigm arguing that the various characteristics and activities described are mutually complementary and so tend to be adopted together with each making the others more attractive in that theory the falling costs of high speed data communication data processing and flexible multitask equipment lead to increases in the directly affected activities which through a web of complementarities then lead to increases in a set of related activities as well although the costs of flexible machinery and data communication and processing surely have fallen substantially in recent decades an analysis that takes these changes as exogenous does not constitute a full explanation of the pattern of change that we observe one must ask why are these particular costs falling relative to others here we enrich the milgrom roberts analysis by adding a dynamic to it innovations in the manufacture of basic inputs both arise in response to a growing market for those inputs and simultaneously encourage that growth this reflects a fundamental complementarity between the level of any activity and investments that reduce its marginal department of economics milgrom and qian and graduate school of business roberts stanford university stanford ca 94305 we thank avner greif for his helpful comments on an earlier draft financial support from the national science foundation milgrom and roberts and the robert and anne bass faculty fellowship roberts is gratefully acknowledged

in markets we trust setting the boundaries of market based instruments in ecosystem services governance abstract a growing tendency to frame environmental problems as a failure to price ecosystem services has coincided with the rise of so called market based instruments mbis the aim of this introductory article to the special section in markets we trust contrasting views on the performance and legitimacy of market based instruments in global environmental governance is to promote critical reflection about the nature scope and limits of mbis in ecosystem services governance and to provide guidance on where the boundaries for the application of markets ought to be set first we examine the role that methodological assumptions and implicit normative positions play in shaping academic perception of the effectiveness and legitimacy of mbis second we examine mbis in the broader ideological context and socio political processes that have favored their development and implementation third we test claims of the literature on mbis against insights and data from case studies presented in the special section fourth we discuss the scope and limits of markets in ecosystem services governance in the light of biophysical institutional and normative boundaries we end with a summary of concluding remarks from the special section and by identifying critical tasks for the scientific and policy agenda on ecosystem services governance

distributional weights in environmental valuation and cost benefit analysis theory and practice abstract cost benefit analysis cba is built on the kaldor hicks efficiency criterion whereby projects that have aggregate positive net benefits are recommended even if those who lose are not compensated for their losses two kinds of problems can be identified with the use of the criterion first as income tends to affect monetary welfare changes positively the preferences of those with higher wealth have a larger weight in societal decision making second monetary welfare changes can be thought of as changes in real income which matter more for those with a lower initial wealth level both problems can be mitigated with distributional weighting despite their strong theoretical pedigree distributional weights have been largely neglected in practical cbas one exception being analyses in climate change economics we present the theory of distributional weighting and illustrate how weights can be applied empirically in an international environmental cba that deals with marine water quality improvements we show that different weighting schemes can result in different policy recommendations we also show that taking the income distribution within countries into account can change a country s willingness to participate in the water quality improvement program and that the income elasticity of willingness to pay wtp is an important indication of the direction of change

searching for sustainability the poverty of spontaneous order abstract traditional approaches to sustainability rely on models that depend upon judgments of welfare across future generations right prices and some sense as to what future persons will find giving of utility these models both accept the spontaneous order of market processes and rely on that order to derive optimal consumption paths into the future sustainability is however not a problem of divining optimal paths predicated upon right prices rather sustainability to be operational requires a prior constructed order predicated upon rights for future persons and duties for those now living who sit in a position as dictator over the settings and circumstances that will be passed on to future persons rights based approaches to sustainability do not rely upon unknowable preferences of future persons but rather upon an environmental regency in which those now living agree to preserve settings and circumstances for the future this reminds us that the issue of sustainability concerns not how much to preserve but what to preserve

hotelling s competition with demand location uncertainty abstract firms product variety choices are examined in a differentiated products model where the range of consumers preferences is an unknown strict subset of the range of potential innovations it is found that the firms locating sequentially will follow the basic pattern of locations found by neven international journal of industrial organization 1987 5 419 434 the uncertainty however generally causes a greater more symmetric amount of differentiation among varieties as firms gamble on finding a market niche with less fierce competition for a sufficiently large pool of potential entrants some firms will lose this gamble and will fail

global mechanisms for sustaining and enhancing pes schemes article i nfo an international payment for ecosystem service ipes schemes may be one of the only mechanisms available to stimulate the provision of vital non marketed ecosystem services at the global level as those nations that benefit from global ecosystem services ges cannot readily force other sovereign nations to provide them currently international trade offers trillions of dollars in incentives for countries to convert natural capital into marketable goods and services and few payments to entice countries to conserve natural capital in order to sustain critical non marketed ecosystem services we examine the biophysical characteristics of climate change and biodiversity to understand the obstacles to developing effective ipes schemes we find that none of the existing schemes for providing ges are adequate given the scale of the problem a cap and auction scheme for co2 emissions among wealthy nations could fund ipes and simultaneously deter carbon emissions to disburse funds we should adapt brazil s icms ecologico and apportion available funds to targeted countries in proportion to how well they meet specific criteria designed to measure the provision of ges individual countries can then develop their own policies for increasing provision of these services ensured of compensation if they do so indirect ipes should include funding for freely available technologies that protect or provide ges such as the low carbon energy alternatives that will be essential for curbing climate change markets rely on the price mechanism to generate profits which rations technology to those who can afford it reducing adoption rates innovation and total value

structured pluralism in ecological economics a reply to peter soderbaum s commentary abstract peter soderbaum argues in his commentary concerning my article on sustainability economics remig 2015 for more open and radical ecological economics i agree with that statement however i reject soderbaum s interpretation that my arguments foster mainstreamed ecological economics or dictatorship in my critique of sustainability economics i raised several issues that have remained unspecified and that potentially lead to unsustainable development patterns once put into practice soderbaum does not reply to these conceptual challenges of sustainability economics in this commentary i argue that structured pluralism dow 2004 is a constituent element of ecological economics i welcome peter soderbaum s proposal for a discussion about the definition of economics and suggest to rely on ronald coase s proposal to define economics as a science that studies the working of the economic system i conclude that sustainability economics in its current form is closer to neoclassical than ecological economics

estimating intergenerational distribution preferences resource management decisions influence not only the output of the economy but also the distribution of utility between groups within the community the theory of cost benefit analysis provides a means of incorporating distributional changes into the decision making calculus through the application of distributional or welfare weights however this practice has not been widely adopted in part due to difficulties in the estimation of distributional weights this paper addresses this problem by using the stated preference method of choice modelling to estimate distributional weights suitable for inclusion in a cost benefit analysis framework the findings of a choice modelling experiment designed to estimate community preferences with respect to intergenerational utility distribution illustrate the potential of this method in addressing distributional issues

aggregation and imperfect competition on the existence of equilibrium we present a new approach to the theory of imperfect competition and apply it to study price competition among differentiated products the central result provides general conditions under which there exists a pure strategy price equilibrium for any number of firms producing any set of products this includes products with multi dimen sional attributes in addition to the proof of existence we provide conditions for uniqueness our analysis covers location models the characteristics approach and probabilistic choice together in a unified framework to prove existence we employ aggregation theorems due to prekopa 1971 and borell 1975 our companion paper caplin and nalebuff 1991 introduces these theorems and develops the application to super majority voting rules we present a new approach to the theory of imperfect competition and apply it to study price competition among differentiated products the central result is that there exists a pure strategy price equilibrium for any number of firms producing any set of products in addition to the proof of existence we provide conditions for uniqueness our model both unites diverse strands of the earlier literature and opens up uncharted areas for future analysis in particular we expand the traditional one dimensional framework to allow for multi dimen sional product differentiation our approach involves twin restrictions on consumer preferences one on individuals preferences the other on the distribution of preferences across society these are generalizations of the restrictions supporting 64 majority rule presented in caplin and nalebuff 1988 to prove existence we apply a new technique of aggregation this technique is valuable in a variety of other problems in the companion paper we use the aggregation result to generalize our earlier work on 64 majority rule and to characterize the relationship between the distribution of human capital and the distribution of income caplin and nalebuff 1991 there are additional applications in statistics and in search theory we begin with a brief review of the early literature on imperfect competition describing in more detail the existence problem and previous solutions section 3 presents our twin assumptions and shows that they cover many standard cases in section 4 we introduce the aggregation theorem and use it in the analysis of demand functions the proof of existence of equilibrium is in section

limits to the value of external costs based on recent insights from the field of risk analysis this paper examines some of the difficulties encountered in attempts to characterise the environmental effects of energy options as monetary externalities more than 20 different dimensions of environmental appraisal are identified and discussed in relation to the historic literature on risk assessment and a number of recent influential environmental valuation studies a survey is conducted of the results obtained over more than a decade for the external environmental costs of electricity supply options theoretical and methodological criticisms are lent support by the finding that environmental valuation results vary over a very wide range of values yielding a variety of rank orderings for the different generating options in addition the values derived for energy externalities are found to be vulnerable to the possible influence of a price imperative the paper concludes by pointing to approaches to the social appraisal of generating technologies which offer greater transparency rigour and accessibility in addressing plural and intrinsically subjective value judgements concerning the different forms and dimensions of environmental effects

reconciling sustainability and discounting in cost benefit analysis a methodological proposal abstract the incorporation of the intergenerational equity objective has rendered the traditional cost benefit analysis cba approach obsolete for the evaluation of projects presenting an important number of environmental externalities and for those whose impacts extend throughout a long period of time based on the assumption that applying a discount rate rewards current consumption and therefore that it is only possible to introduce a certain intergenerational equity in a cost benefit analysis in this work we propose an approach to discounting based on a different rationale for tangible and intangible effects we designed two indicators of environmental profitability a the intergenerational transfer amount ita which quantifies in monetary units what the current generation is willing to pass on future generations when an environmental restoration project is carried out and b the critical environmental rate cer measures the implicit environmental profitability these concepts were tested through an empirical case study pertaining to the assessment of an erosion control project in the southeast of spain the results yield traditional profitability indicators that are higher and probably closer to the real values set by the contemporary society the information provided by the environmental profitability indicators proposed renders more transparency to the quantification of the levels of intergenerational equity applied thereby facilitating the difficult reconciliation of the cba technique with the objective of sustainability

institutions and environmental governance a reconceptualization abstract this article presents the conceptual revisions needed to extend the new institutional approach to environmental governance from its current local and international domains of application to all governance solutions including national environmental and natural resource use policies and multi level governance solutions that are increasingly used to address global environmental change the article suggests that environmental governance is best understood as the establishment reaffirmation or change of institutions to resolve conflicts over environmental resources it also explains why the choice of these institutions is a matter of social justice rather than of efficiency the article suggests a way to understand formal and state centered governance solutions as forms of collective ownership not unlike common property the article demonstrates how institutional analysis can gain resolution by looking at the functional and structural tiers organization of governance functions and formulation of key institutional rules as key aspects of the design of governance institutions

uncertain spatial demand and price flexibility a state space approach to duopoly abstract sufficient conditions for a unique price equilibrium in terms of the uncertainty distribution and the state contingent consumer distributions are given for spatial duopoly also considered are efficiency and endogenous locations for the symmetric case and comparative statics on price flexibility

linking economic complexity institutions and income inequality summary a country s mix of products predicts its subsequent pattern of diversification and economic growth but does this product mix also predict income inequality here we combine methods from econometrics network science and economic complexity to show that countries exporting complex products as measured by the economic complexity index have lower levels of income inequality than countries exporting simpler products using multivariate regression analysis we show that economic complexity is a significant and negative predictor of income inequality and that this relationship is robust to controlling for aggregate measures of income institutions export concentration and human capital moreover we introduce a measure that associates a product to a level of income inequality equal to the average gini of the countries exporting that product weighted by the share the product represents in that country s export basket we use this measure together with the network of related products or product space to illustrate how the development of new products is associated with changes in income inequality these findings show that economic complexity captures information about an economy s level of development that is relevant to the ways an economy generates and distributes its income moreover these findings suggest that a country s productive structure may limit its range of income inequality finally we make our results available through an online resource that allows for its users to visualize the structural transformation of over 150 countries and their associated changes in income inequality during 1963 2008

assessing natural resource damages using environmental annuities abstract although research methods exist to place economic values on lost wetland service flows in many circumtances the cost of conducting such research exceeds the expected value of damages in some cases sufficient time may not be available to undertake primary research in addition the existing wetland valuation research base is often inadequate to support defensible benefits transfer as an alternative to more traditional valuation techniques we propose a simplified approach based on environmental annuities the principal assumption behind this approach is that the public can be compensated for past losses in environmental services through the provision of additional services of the same type in the future an application of this approach as the basis of a recent natural resource damage claim is described

valuing lives equally distributional weights for welfare analysis abstract distributional weights for welfare analysis are proposed based on two axioms 1 all lives are equally valued 2 the monetary value of a person s life is her own valuation this implies weights proportional to the reciprocals of the values of statistical lives

on the meaning of economic efficiency in policy analysis there are crucial differences in the normative foundations of alternative economic cri teria used to assess the efficiency of policy pro posals differences between pareto and potential pareto measures are emphasized in this comparison of efficiency standards technical distinctions be tween these two criteria are examined and illus trated it is argued that potential pareto criteria have greater disciplinary acceptance than their nor mative foundations merit and further that the pareto measure has suffered undue criticism from association with its potential pareto namesake jel all

toward a new welfare economics for sustainability the debate over various definitions of sustainability has for the most part been conducted within the framework of traditional welfare economics discussion has centered on technical issues imbedded within the functional forms of various optimization models especially the coefficient of the elasticity of substitution and the social discount rate two more basic problems are 1 intractable theoretical difficulties within welfare economics call into question the results of traditional models of sustainability regarding intergenerational welfare and 2 equating per capita consumption with welfare contradicts empirical evidence suggesting that the link between happiness and wealth income is relatively weak alternative approaches to measuring well being are being developed and these have great potential to move the sustainability debate forward

entitlements missing markets and environmental uncertainty reply abstract at one level dore and ward seem intent on immunizing received doctrine they say that i did not prove that rights violated nozick s principles of justice and that i did not prove that missing markets were the problem more telling they allege i did not prove that my story was better than the particular story favored by dore and ward that is they argue that there is an alternative approach based on the theory of public economics which is indeed operational 3 they then use the bulk of their comment to explain and defend this alternative model they hope to convince the reader that the model of public economics survives intact in the face of my alternative model to the extent that their model allows one to define the problem away it is not difficult to see why they find it so compelling more seriously dore and ward fail to make a coherent argument about the concept of rights and duties and the logic of a particular rights structure that happens to prevail they seem concerned that my article was tampering with some sacred social construct the status quo rights structure and that my article threatened the received wisdom of both public economics and paretian walrasian bliss indeed theirs seems to be a genuine fear that if economists release their grip on the certitude of received orthodoxy the floodgates will be open to all manner of bumbling regulators seeking to shift rights and wealth positions across generations my article is apparently threatening because it seems to suggest that the received wisdom may at times be misleading

institutional ecological economics abstract new institutional economics and its forerunners have we argue made important contributions to the evolving agenda of ecological economics the conceptualisation of environmental problems as instances of interdependence and the acknowledgement of positive transaction costs are key insights into the nature of environmental problems we also discuss how plurality of behavioural motivations and limited cognitive capacity have important implications for environmental decision making and its analysis we show how evolutionary and collective action theories offer complementary takes on the choice and change of environmental governance institutions and how the concept of social capital can enrich analyses of environmental governance we conclude that an emerging institutional ecological economics has the greatest relative advantage in analysing the design implementation and effectiveness of environmental governance solutions

economic valuation of the environment how citizens make sense of contingent valuation questions this study adopts a qualitative approach in order to investigate how people make sense of contingent valuation cv questions of a global environmental amenity the objective is not only to capture people s motivations and considerations of willingness to pay wtp but also to determine if they adequately comprehend an economic valuation of such public goods the findings indicate that a large proportion of respondents do not interpret the valuation task as intended however this lack of understanding is not always expressed unless probed in relation to the elicitation question and some people have the tendency to provide monetary estimates anyway whatever meaning they attach to these

altruism evolution and welfare economics henrich clearly presents the convincing evidence that the evolution of prosocial preferences altruism and altruistic punishment is both theoretically possible and empirically present in human populations henrich convinces us using only the most restrictive arguments if one goes beyond the assumptions of one gene one trait or recognizes the existence of social cognition caporael 1997 the case for the existence of prosocial behavior is overwhelming furthermore while henrich is probably correct in saying that large scale social cooperation is unique to the human species mounting evidence suggests that prosocial behavior is also present in such diverse non human species as lions meerkats fire ants and arabian babblers clutton brock 2002 so why is the reaction against the notion of pure altruism so strong in both economics and biology a likely reason is that it goes against the dominant cultural belief in progress through competition among individuals both evolutionary biology and political economy matured in victorian england where darwin s careful and cautious argument for evolution by natural selection was recast as survival of the fittest a metaphor which fit the dog eat dog world of commercial society rugged individualism is reflected in the gene based reductionism of biology as well as the agent based reductionism of welfare economics bergh and van den gowdy 2003 in his contribution henrich establishes the theoretical basis for cultural group selection based on large scale cooperation he shows that the existence of prosocial behavior cannot be explained by individual based characteristic alone such as kin selection reciprocal altruism or costly signaling this does not contradict darwinian natural selection which can operate on any statistically reliable pattern patterns of culture may vary widely in human societies based on the different kinds of cultural transmission including conformist transmission a short cut to reliable information prestige based transmission punishment of non conformists and normative conformity by which people want their behavior to match that of the group the interplay between these kinds of cultural transmission and the in

incommensurability and monetary valuation at the very heart of environmental cost benefit analysis cba is the claim that benefits and costs can be expressed in terms of money and hence made comparable in particular cba puts all benefits and costs on a cardinal monetary scale it assumes monetary commensurability a significant literature in ethics and political philosophy has arisen which doubts this assumption but has so far had little impact on the theory or practice of cba in light of this the paper assesses the defense of monetary commensurability offered by cost benefit analysts and the wider economics literature

influences of transaction costs in environmental policy abstract there is a growing literature reporting the extent of transaction costs for environmental policies however understanding why transaction costs occur and why they are small or large is also important for efficient policy selection and evaluation following an analysis of the organisational economics literature and reports of the extent of transaction costs for a number of environmental policies three key influences to transaction costs in environmental policies are identified these are the following 1 the characteristics of the transaction for the environmental good 2 the nature of the transactors and 3 the current institutional environment and arrangements these affect transaction costs to the government and all other parties influenced by a policy transaction costs occur due to actions of information collection and policy design policy enactment and establishment implementation and contracting administration and monitoring and enforcement an interrogation of transaction cost influences reveals that 1 the influence varies between parties and is affected by the actions and interactions of and between all parties to a policy 2 how transaction costs are experienced varies across time and 3 who experiences transaction costs depends on the policy itself future policy selection and refinement will benefit from empirical analysis of the causes of transaction costs

the impact of economics on environmental policy abstract environmental economists have seen their ideas translated into the rough and tumble policy world for over two decades they have witnessed the application of economic instruments to several environmental issues including preserving wetlands lowering lead levels and curbing acid rain this essay examines the impact of the rise of economics in the policy world on the making of environmental policy i focus on two related but distinct phenomena the increasing interest in the use of incentive based mechanisms such as tradable permits to achieve environmental goals and the increasing interest in the use of analytical tools such as benefit cost analysis in regulatory decision making i argue that economists and economic instruments have had a modest impact on shaping environmental health and safety regulation but that economists will play an increasingly important role in the future although the role of economics is becoming more prominent it does not follow that environmental policy will become more efficient this apparent inconsistency can be explained by the political economy of environmental policy

variety complexity and economic development abstract we propose a combinatorial model of economic development an economy develops by acquiring new capabilities allowing for the production of an ever greater variety of products with an increasing complexity taking into account that economies abandon the least complex products as they develop over time we show that variety first increases and then decreases in the course of economic development this is consistent with the empirical pattern known as the hump our results question the common association of variety with complexity we further discuss the implications of our model for future research

the equity efficiency trade off in environmental policy evidence from stated preferences the design of environmental policy raises several equity issues in particular the distribution of benefits and costs at the same time it has often been argued that there is a trade off in environmental policy between equity and efficiency which brings these issues firmly to the attention of environmental economics in this paper we use a simple choice experiment to elicit individual preferences over equity efficiency trade offs in the context of two environmental problems local air pollution and global climate change we find that equity matters to people as much as efficiency does in the design and delivery of environmental policy

reducing protest responses by deliberative monetary valuation improving the validity of biodiversity valuation this paper focuses on examining the validity of biodiversity valuation methodologies the results of a group deliberation technique deliberative monetary valuation are compared to those derived from a contingent valuation cv survey using the same environmental topic evidence is here presented that dmv can address some of the limitations of cv namely a prevalence for lexicographic preference ordering due to psychological reasons and the lack of a priori or well formed preferences both of these methodological shortcomings can result in protest responses which decrease the external validity of results it is common environmental valuation methodology practice to exclude protest responses from the analysis on the grounds that they are illegitimate choices thus the sample and consequently the environmental valuation analysis may become less representative of the population an advantage of the dmv methodology is that it was found to significantly reduce the rate of protest responses to less than half from 29 to 13 furthermore dmv significantly increased the proportion of positive bids but not the amounts contributed in relation to preference formation issues we suggest rethinking the current practice of the dmv method and propose dedicating the entire initial discussion session to introducing the good outside of a valuation context

externalities a market model failure we focus here on a set of conceptual problems related to the accepted theory of externalities we are primarily concerned with difficulties that arise when a theoretical system is extended beyond its logical domain this is the practice in externality theory when the market model assuming independent agents is used to analyze physical interdependency the different kinds of dependencies obscure the standard use of the paretian analysis as the issues of rights and efficiency are mixed up the creation of emissions and the creation of externalities are further not held apart producing flows in the efficiency evaluations due to the interdependencies involved actions of both emitter and victim must be taken into account while searching for efficient policies finally we analyze the interrelationships between what is termed the internal structure of the market model and the annexed sphere of externalities we conclude that the accepted policy prescriptions both assume and demand no interrelationships between these two spheres we find the assumption unrealistic and inconsistent as concerns the basic foundations of the market model there are two main traditions addressing externalities the coasean and the pigovian this paper shows that both are vulnerable to the above critique thus the presumption that externality theory is now settled and coherent is seen to be without theoretical support

i struggled with this money business respondents perspectives on contingent valuation abstract in the long running debates about the validity and legitimacy of contingent valuation cv very little research has engaged directly with respondents during or after the survey to explore what individuals willingness to pay wtp figure meant this paper presents the results of qualitative research with respondents to a cv survey carried out as part of the appraisal of a specific nature conservation policy in the uk the results show that respondents questioned the validity of their wtp figures through discussion of the difficulties they experienced in framing a meaningful reply significant difficulties included problems in contextualising what the scheme was and how much it might be worth in both monetary and non monetary terms an inability to work out a value for one scheme in isolation from others in other parts of the uk and feelings that values for nature were not commensurable with monetary valuation turning to the legitimacy of cv participants in the research challenged claims that cv is a democratic process for ensuring that public values are incorporated in policy decisions recognizing that hard economic choices have to be made in order to achieve nature conservation goals participants argued for a decision making institution where local people could contribute to environmental policy decisions through dialogue with scientists and policy makers in the final part of the paper this project is compared with three studies that have also used qualitative approaches with respondents during and or after a cv survey the paper concludes that more context specific qualitative research with respondents is needed to explore further the conclusion that cv may not be a good methodology for capturing complex cultural values for nature and landscape

the sophistication of exports a new trade measure summary trade data are often classified by product characteristics we propose a new classification sophistication as a means of distinguishing between products we construct a sophistication index based on the income levels of exporting economies sophistication captures a range of factors including technology ease of product fragmentation natural resource availability and marketing we calculate sophistication scores at the 3 and 4 digit levels and test how far the index relates to existing technological classifications of products we use the index to examine trade patterns and illustrate how it can be applied in the analysis of export performance of individual economies

towards a fair constructive and consistent criticism of all valuation languages comment on kallis et al 2013 we provide critical notes to the paper by kallis et al 2013 on monetary valuation we evaluate the four criteria they propose for assessing valuation studies we argue that no clear distinction is made between monetary valuation and pricing instruments the selected criteria are more relevant to assessing policy than monetary valuation the examples provided are not representative of the diversity of valuation studies encountered in the literature moreover no clear examples are provided of where valuation and associated cost benefit analysis of environmental policy go wrong we plea for a more fair constructive and consistent criticism of all valuation languages and offer relevant issues for consideration

the true index of cost of living under general equilibrium the numeraire matters abstract the evaluation of welfare effects should be unambiguous we show that the konus true index of cost of living is numeraire dependent in general equilibrium this may lead to ambiguous even contradictory interpretations of welfare results to correct this problematic interpretational situation we propose a normalization of the standard konus index using an endogenously determined price index we also provide a simplified expression of the index for the special case of homothetic utilities which is especially relevant given their widespread use in numerical general equilibrium

the limits of monetization in valuing the environment a reply to gsottbauer et al we welcome the attention of gsottbauer logar and van den bergh thereinafter glv to our contribution however their critique misrepresents what our article was trying to do so it merits a response our article offered a framework for assessing the conditions under which one may or may not engage with processes that value nature in money terms glv argue that first we confuse monetary valuation methods with pricing policies and that most of what we have to say may be relevant for the latter but not for the former second they argue that the assessment criteria we propose are either obvious or unconvincing third they contend that the examples we give to illustrate the applicability of our criteria are not representative and finally they suggest that our concern with whether a particular monetary valuation study or pricing policy contributes to enclosures and neo liberalism is ideological an

preferences in the future environmental economics has been much occupied with the discount rate which is the value of future costs and benefits relative to present costsor benefits but at least as important is the question of whatshould be discounted that is what the value of those future environmentalbenefits is to future generations this paper analyzes the role for futurepreferences and discusses the state of knowledge i argue that theappropriate discount rate is the market one and that the real problemis determining future willingness to pay this approach makes clearerthe connection between discounting and the valuation debate this paper focuses on two features that have been prominent in that debate existence value and reference dependence i argue that thereis a vital connection between the two constructs and that this link yieldsimportant implications for future willingness to pay

product differentiation and location decisions under demand uncertainty we investigate hotelling s duopoly game of location then price choices with quadratic transportation costs and uniformly distributed consumers under the assumption that firms are uncertain about the exact location of demand we characterize the unique equilibrium and the socially optimal locations contrary to the individual level random utility models location uncertainty is a differentiation force in equilibrium increases in the variance of the uncertainty lead to greater differentiation higher expected equilibrium prices and profits and a greater welfare loss

the barely revealed preference behind road investment priorities an attempt is made to reveal the preference of decision makers within the regional norwegian public roads administration the order of priority assigned to the respective competing public road investment opportunities within the various counties provinces is studied by means of a rank order multinomial logit model explanatory variables used include cost benefit and a variety of attributes characterizing the individual investment projects although statistically significant cost and benefit appear to be of only marginal importance for the priorities set more weight is attached to cost than to benefit smaller projects are preferred to larger given the benefit cost ratio in general the models estimated are able to explain only a relatively small share of the priority setting made

disaggregated economic impact analysis incorporating ecological and social trade offs and techno institutional context a case from the western ghats of india economic valuation of ecosystem benefits and their aggregation in a benefit cost analysis bca framework is the norm in mainstream environmental economics but valuation and bca have also attracted criticisms internal criticisms point to the absence of alternative scenarios in valuation overlooking of ecological trade offs and dis services and inattention to context others criticize aggregation across diverse stakeholders and the problem of non monetizable benefits and dismiss bca as fatally flawed they suggest approaches such as deliberative decision making and multi criteria analysis we propose a middle path that uses the strengths of economic analysis for decision support while avoiding the pitfalls we disaggregate economic impacts by stakeholder groups link ecosystem changes to benefits as well as dis benefits and examine how socio technological context shapes the magnitude of economic impact we illustrate this approach by studying the impact of creating the biligiri rangaswamy temple wildlife sanctuary in the western ghats forests of southern india our analysis shows that while some stakeholders are net beneficiaries others are net losers changes in forest rights irrigation technologies and ecosystem dynamics influence the magnitude of benefits and sometimes convert gainers into losers such disaggregated analysis can provide useful information for deliberative decision making and important academic insights on how economic value is generated

the sustainable residential water use sustainability efficiency and social equity the european experience abstract the present paper traces the operational conditions governing the sustainable use of water in cities towards this objective the paper first proposes a new comprehensive definition for the sustainable use of water next efficiency in use is proposed as a fundamental instrument in achieving sustainability in spite of prevailing opinions maintaining that sustainability and efficiency aim at different and probably conflicting objectives in this light several pricing modes that inhibit efficiency are examined and their effects are defined in this context egalitarian pricing which nevertheless prevents efficiency is also systematically evaluated until it is ascertained that it does not serve social equity in the use of water in the long run all the more the present paper advocates that certain egalitarian pricing systems such as the increasing block rates most prevalent at this time may have the reverse effect than the one intended and hence in the long run impose negative impacts on the welfare of low incomes as a result full cost prices are proposed as a necessary instrument for the sustainable use of water an instrument that promotes social equity in the long run the assumptions of the study are examined in a comparative analysis of representative european pricing systems and urban management modes

experimentation and learning in a differentiated products duopoly abstract this paper explores price setting behavior in the context of a duopoly in which firms are uncertain about the degree of product differentiation firms learn from the difference in their realized demands in light of the price differential the informativeness of this market experiment is shown to be increasing in size of the price differential in markets with highly substitutable products price dispersion is enhanced as firms adjust their prices so as to generate more information in markets with highly differentiated products firms compress their prices as they prefer to reveal less about the extent of product differentiation journal of economic literature classification numbers d43 d83 l13

the numeraire matters in cost benefit analysis abstract the choice of numeraire is shown to be important in cost benefit analysis when a public good is involved individual consumers marginal rates of substitution will generally differ thus the less valuable the numeraire is to a person the higher the number required to express his net benefit and the more will his interest weigh in the total sum the choice of money as numeraire is systemetically favourable to those who value money the least relative to alternative numeraires

the virtual aquarium commodity fiction and cod fishing abstract this article deals with the commoditization and pricing of environmental goods in particular the practice and social theory of individual transferable quotas itqs in fisheries emphasizing ethnographic material related to the management system introduced in iceland in 1984 icelandic fisheries discourse i argue is increasingly textual and hegemonic dominated by marine scientists resource economists and state officials at the same time the allocation and exchange of quotas are matters of an ongoing moral debate this debate i suggest reflects the politics of independence and equity in icelandic history as well as a deeper concern in western society with the status of money and monetary exchange a concern that has a number of parallels in other parts of the world

should a central bank transfer its profits to the treasury in this paper we show how two seemingly irrelevant accounting principles for central banks namely the choice of the unit of account for its balance sheet and the method of inventory valuation of foreign currency reserves can overstate or understate profits transferred to the treasury and how this can threaten the ability of central banks to control inflation we show the first point through monte carlo experiments calibrated for the venezuelan economy and the second point in an infinitely lived representative agent model that illustrates the problem of the joint determination of the level of central bank assets and the size of profits transferred to the treasury when the objective of the central bank is to eliminate the possibility of hyperinflation

project analysis as input to public debate environmental valuation versus physical unit indicators abstract monetary valuation of environmental change is useful if one aims to rank alternative projects according to some specific social welfare function however if the project analysis is intended as background information to a democratic debate the advantages of monetary valuation are less obvious this paper analyzes aggregation of information taking normative disagreement explicitly into account it is demonstrated that monetary valuation is not always more informative than a physical unit measure of environmental change

monetary valuation of ecosystem services it matters to get the timeline right in the abundant literature dealing with the monetary valuation or monetization of ecosystem services mes with very few exceptions the concept is presented as having emerged in 1997 in fact there is a long history starting in the late fifties but largely ignored of sustained attempts to assign monetary values to nature s services these early efforts encountered many conceptual and methodological roadblocks which could not be resolved and led a number of researchers to argue that monetary valuation was not a fruitful approach it is in that context that mes was hailed by some in 1997 as a promising way to integrate environmental goods and services into the logic of economic markets knowledge of the full timeline casts a very different light in particular on the difficulties currently encountered in the practice of mes far from being the expected growing pains of a young discipline these difficulties turn out to be long standing problems that have eluded solution over the last half century and appear intrinsically unresolvable this perspective suggests that at this point it is advisable to look at alternatives to mes for the integration of nature into economic decisions

environmental regulations and the problem of sustainability moving beyond market failure abstract the standard metaphor of market failure is an impediment to the crafting of environmental policy that can escape policy lock in sustainability requires a policy process that can avoid this lock in sustainability concerns the creation of dynamic human processes that can respond to indeed anticipate unanticipated feedback from biological processes

export sophistication and economic growth evidence from china we consider the effect of export sophistication on economic performance by appealing to regional variation within one single country china over the 1997 2009 period we find evidence in support of hausmann hwang and rodrik 2007 in that regions specializing in more sophisticated goods subsequently grow faster we find substantial variation in export sophistication at the province and prefecture level controlling for the level of development and that this sophistication in turn drives growth our results suggest that these gains are limited to the ordinary export activities undertaken by domestic firms no direct gains result from either processing trade activities or foreign firms even though these are the main contributors to the global upgrading of china s exports as such the extent of assembly trade and foreign entities should be distinguished in order to measure the true movement in a country s technology and the contribution of exports to economic growth

the cold shiver of not giving enough on the social cost of recycling campaigns governments sometimes try to increase individuals contributions to public goods through appeals to consumer responsibility rather than by economic incentives for example in recycling campaigns using standard consumer theory one would hardly expect such campaigns to work at all but if consumers are motivated by norms appeals may work through changing consumers perception of the normrequirement however increasing voluntary contributions through appeals may come at a social cost the reason is that appeals work through imposing a heavier perceived responsibility on consumers this represents a welfare loss which is not necessarily outweighed by warm glow benefits

does aid for trade diversify the export structure of recipient countries the importance of aid for trade as a tool for facilitating trade economic growth and social development has received attention since the concept was introduced in 2005 while one of the main targets of aid for trade is export diversification reflecting the fact that the exports of many developing countries are concentrated in a small range of items there have not been many efforts to measure the effect of aid for trade on export structure this study therefore attempts to trace the relationship between aid for trade and 133 aid recipients export structure between 1996 and 2013 using the herfindahl hirschman index to measure the degree of export concentration the findings suggest that total aid for trade has reduced the concentration level in the short run in the long run on the other hand aid for trade has had no significant effect on export structure of recipient countries only aid for building productive capacity which is one of the three categories of aid for trade contributes to lower concentration yet this change is not caused by an increase in export diversity but by the redistribution of shares of existing products of a similar sophistication level

limits to cba in uk and european environmental policy retrospects and future prospects this paper reviews the contemporary debate and the now long standing role of cba in uk and european environmental policy appraisal epa and looks forward to possible future applications the position taken is that despite its limitations cba still has an important part to play in epa however with the increasingly contested nature of environmental and related public policies and outcomes its role will become less prescriptive and its findings more constrained by social justice and ethical imperatives future cba is more likely to continue to flourish as a component in a wider policy analysis and decision support system whatever decision support system is eventually adopted its value will be judged on how well it aids real policymakers operating iteratively in the non linear real world political economy

measuring potential rents in the north sea herring fishery this paper assesses the potential for rent generation in the north sea herring fishery the assessment distinguishes between rents and intra marginal profits the sum of which constitutes variable profits in the fishery a bioeconomic model combining fish population dynamics and the economics of the fishery is constructed to allow the computation of these different components of profits in order to assess the dynamics of both rents and intra marginal profits the model is computed under various assumptions with regard to price costs and discount rates potential total profits are measured at 88 to 89 million annually of which rents make up about 87 million with intra marginal profits measured in the order of only 2 million the study further shows that in this fishery rent is dissipated mainly due to excess effort but also due to suboptimal stock size

changing trade structure and its implications for growth there is a long tradition in the development literature that what a country exports matters for its growth prospects recent work has refocused on this issue by attempting to produce numerical scores for different types of product to identify the complexity or sophistication of a country s export basket based on the insight that the type of product an economy exports can have important implications for its economic performance and that goods exported predominantly by rich countries will have different characteristics from those exported by poor countries lall et al 2006 put forward a means of classifying commodities based on the income levels of a product s main exporters at around the same time hausmann et al 2006 following a similar approach put forward a slightly different form of product classification and rodrik 2006 applied this specifically to an analysis of china this paper highlights the difference between the approaches and its implications for the analysis of china which appears less special using the approach of lall et al it argues that the classification of products at a disaggregate level is a helpful starting point for assessing issues of trade competitiveness and that further work using either or both forms of classification is justified

compensating for environmental damages this paper examines a situation in which a decision maker determines the appropriate compensation that should be awarded for a given amount of ecological damage the compensation can take the form of either or both monetary and environmental units to meet three goals i minimisation of the cost associated with the compensation ii no aggregate welfare loss and iii minimal environmental compensation requirement the findings suggest that in some cases providing both monetary and environmental compensation can be the cost minimising option minimal compensation constraints can increase total compensation costs but reduce individual gains and losses relative to the initial situation that arise from heterogeneous tradeoffs between income and environmental quality

the necessity for environmental taxes for the avoidance of environmental thievery a note on the paper environmental responsibility versus taxation abstract internalizing environmental costs is a necessary condition for an effective environmental policy since the majority of socio economic activities cannot be free of environmental impacts the noninternalized external environmental costs impose a peculiar thievery of welfare charging environmental costs through environmental taxes and other economic instruments is a necessary condition for avoiding welfare thievery in this context the anti tax approaches emerging within ecological economics are found to be misleading and directing away from an effective environmental policy environmental responsibility is a different issue from the charging of the environmental costs therefore environmental taxes should not be considered as an induction to less environmental responsibility and hence to environmental degradation

unraveling the veil of fuzziness a thick description of sustainability economics this article provides a thick description geertz 1973 of sustainability economics baumgartner and quaas 2010a b have proposed as an alternative to ecological economics the new field of sustainability economics which has triggered various replies the purpose here is to order and to review these contributions building upon a literature review of sustainability economics the paper argues that the concept currently has more of a fuzzy and declamatory character the rhetoric mccloskey 1998 of sustainability economics contains general issues of sustainability economics externalities and the capability approach the article argues that it is currently not clear how the solutions for science and policy proposed by sustainability economics differ from those of ecological economics efforts should be directed towards further development of the theory and the operationalization of sustainability principles the systemic view of co evolutionary development social learning and sustainability economics normative underpinning merits more consideration in the debate about sustainability economics
