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

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

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

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

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

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 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

energy and the long cycles abstract the hypothesis is submitted in this paper that energy directly or indirectly had much more to do with the generation of the long kondratiev cycles than generally recognized an attempt is made to test this and it is suggested that the next upturn may also be energy related

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

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 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

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

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 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

historical energy price shocks and their changing effects on the economy abstract the purpose of this paper is to identify the changes in the impact of energy shocks on economic activity with an interest in assessing if an economy s vulnerability and resilience to shocks improved with economic development using data on the united kingdom over the last three hundred years the paper identifies supply aggregate demand and residual shocks to energy prices and estimates their changing influence on energy prices and gdp the results suggest that the impacts of supply shocks rose with its increasing dependence on coal and declined with its partial transition to oil however the transition from exporting coal to importing oil increased the negative impacts of demand shocks more generally the results indicate that improvements in vulnerability and resilience to shocks did not progress systematically as the economy developed instead the changes in impacts depended greatly on the circumstances related to the demand for and supply of energy sources if these experiences are transferable to future markets a transition to a diversified mix of renewable energy is likely to reduce vulnerability and increase resilience to energy price shocks

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

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

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

self organization and sustainability energetics of evolution and implications for ecological economics abstract in the 1920s alfred lotka suggested that evolution results both in an increasing total energy flow through the biosphere and in increasing energy efficiency of biological processes later authors attempted to generalize lotka s conjectures and to transform them into general evolutionary laws these laws are derived from the laws of thermodynamics and it is frequently argued that they also apply to the development of economic systems in the present paper an alternative interpretation of the lotka principles is suggested which starts from the self organization of dissipative structures self organization concepts from ecological and evolutionary economics are integrated on this basis energetic regularities in evolutionary processes are interpreted as emergent properties of competitive self organization given the close relationship between energy dissipation in economic processes and various environmental problems thermodynamic effects of economic evolution are of practical policy relevance the evolutionary perspective taken here implies that policy measures toward sustainable development will primarily have to affect the kinds of innovative behavior triggered in competitive processes

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

experimentation with accumulation abstract we study signal dependent experimentation in the presence of accumulation and show that the passive learner s action surprisingly coincides with the experimentor s when the unknown term is the one determining the decay rate of the stock while they differ when the parameter being learned is the one measuring the accumulation rate these results highlight the importance of the dynamic structure of the problem in signal dependent experimentation moreover they have important consequences for the pollution accumulation debate currently in progress

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

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

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

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

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
