limited rationality and strategic interaction the impact of the strategic environment on nominal inertia much evidence suggests that people are heterogeneous with regard to their abilities to make rational forward looking decisions this raises the question as to when the rational types are decisive for aggregate outcomes and when the boundedly rational types shape aggregate results we examine this question in the context of a long standing and important economic problem the adjustment of nominal prices after an anticipated monetary shock our experiments suggest that two types of bounded rationality money illusion and anchoring are important behavioral forces behind nominal inertia however depending on the strategic environment bounded rationality has vastly different effects on aggregate price adjustment if agents actions are strategic substitutes adjustment to the new equilibrium is extremely quick whereas under strategic complementarity adjustment is both very slow and associated with relatively large real effects this adjustment difference is driven by price expectations which are very flexible and forward looking under substitutability but adaptive and sticky under complementarity moreover subjects expectations are also considerably more rational under substitutability

a framework for the practical application of the concepts of critical natural capital and strong sustainability this paper develops a methodology for identifying that natural capital called critical natural capital cnc the maintenance of which is essential for environmental sustainability by consideration of the characteristics of natural capital of the environmental functions that these characteristics enable natural capital to perform and of the importance of these functions to humans and the biosphere it shows how sustainability standards in respect of these environmental functions may be derived the difference between the current situation and these standards is termed the sustainability gap the methodology that emerges from bringing these ideas together into a single analytical framework enables policy makers to identify the extent of current unsustainability the principal causes of it the elements and processes of natural capital the cnc which need to be maintained or restored to close the sustainability gap and the costs of so doing the framework should therefore be of use in identifying priorities and policies for moving towards environmental sustainability

the epistemological challenge of self modifying systems governance and sustainability in the post normal science era abstract in this paper we conceptualize the difference among risk uncertainty and ignorance and focus on a theoretical analysis of modeling relation applied to self modifying systems within the framework of post normal science we provide an overview of the concept of risk and uncertainty elaborating on the work of f knight we extend r rosen s theory of modeling relation originally aimed in natural science to the issue of science for governance knight s analysis of risk and uncertainty can be used to generate a list of various types of uncertainty involved in every stage to model self modifying systems such a list is relevant for gaining insight into the issue of science for governance it is important for those attempting to model sustainability especially in the field of ecological economics to be aware of the theoretical difference between models and similes for self modifying systems

quantification of interdependencies between economic systems and ecosystem services an input output model applied to the seine estuary abstract the aim of this paper is to assess the possible contribution of an input output model towards two of the basic principles of the sustainability strategy of integrated coastal zone management iczm and post normal science according to these principles decision support tools should offer a holistic perspective and handle high uncertainty the difficulties in reaching sustainability are due partly to the prevailing use of narrow system boundary tools that are non holistic consequently they fail to capture important ecosystem services and ignore interdependencies between them to comply with the basic principles our method allows environmental assets to be evaluated in multiple units and integrates results from recent researches in natural sciences both enable coverage of interdependencies between ecosystem services thereby we enlarge input output modelling from the two conventional ecosystem services of sink and provisioning to the most vital ones the supporting services an application to the seine estuary addresses the impacts of maritime transportation infrastructures on nursery habitats for commercial fish the ecosystem services covered are life support and resource provisioning our results show that the restoration of a total of 73 7 km 2 of nursery areas over the period 2004 2015 would result in a stock of sole in 2015 that exceeds the business as usual scenario by 44 2 uncertainty range 35 9 69 9 in spite of high restoration costs the negative macro economic impact is very low however on the sector level a trade off results between nurseries and three economic sectors the quantification of such trade offs in our model is particularly useful to public participation in decision making

valuing fisheries depreciation in natural resource accounting the pelagic fisheries in northeast peninsular malaysia in this paper an approach based onthe net present value method is used to account forthe changes in the value of fisheries resources changes in the value of fisheries resources can occurbetween successive years catch as well as betweencurrent and optimal levels of catch these changesneed to be accounted for in the national accountingsystem to reflect the true net national income thatis sustainable the approach outlined in this paper isdesirable as it allows the estimation of thedepreciation value of fisheries resource with limitedbiological information the application of theapproach to the pelagic fisheries in northeastpeninsular malaysia nepm showed that the resourcedepreciated in value over most years from 1982 to1993 these depreciations correspond to increasedfishing effort in addition pelagic catches in nepmfrom 1982 to 1993 were lower than the optimal levelsof catch due to overfishing thus policies aimed atreducing fishing effort can provide improvement inboth the potentially higher capital values of thefishery resource and the earning potentials of thefishing industry in nepm

social multi criteria evaluation methodological foundations and operational consequences in order to address contemporary issues economics and decision sciences need to expand their empirical relevance by introducing more and more realistic thus more complex assumptions in their models one of the most interesting research directions in the field of public economics is the attempt to introduce political constraints interest groups and collusion effects explicitly j j laffont incentives and political economy 2000 the main argument developed here is the proposal of the concept of social multi criteria evaluation smce as a possible useful framework for the application of social choice to the difficult policy problems of our millennium where as stated by funtowicz and ravetz facts are uncertain values in dispute stakes high and decisions urgent this paper starts from the following main questions 1 why social multi criteria evaluation 2 how should such an approach be developed the foundations of smce are set up by referring to concepts from complex system theory and philosophy such as reflexive complexity post normal science and incommensurability to give some operational guidelines on the application of smce basic questions to be answered are 1 how is it possible to deal with technical incommensurability 2 how can we deal with the issue of social incommensurability to answer these questions using theoretical considerations and lessons learned from real world case studies is the main objective of the present article

operationalizing sustainable development dynamic ecological economic models abstract since the mid eighties a vast literature has evolved around the concept of sustainable development it shows a wide support for changes in policy making and decision making for instance to integrate environmental interests in national and international political processes remarkably recommendations of contours and new elements of research methods and policy analysis for sustainable development are rare although this is just as essential as the renewed attention for the political dimension a clear view on how to use and change adequately existing techniques and models for sustainable development will contribute to a more satisfactory operationalization of it this paper examines the implications of ecologically sustainable economic development for integrated dynamic modelling after a concise discussion of sustainable development it is suggested that five concepts are central to it intergenerational equity the regional scale multiple use long term uncertainty and economic ecological integration the discussion of each of these issues is focused on the implications for model elements and uses thereby old ideas are reviewed and new ones are proposed the aim is not to come up with a rigid framework for dealing with sustainable development but rather to suggest which alternatives are available to deal with the central concepts although in a section on economic ecological integration general requirements for dynamic economic ecological models are mentioned explicitly in order to offer a general frame of reference these requirements are fairly general and may be taken up in ensuing discussions of the methodological aspects related to sustainable development the main conclusions are the following we view economic ecological integration in the sense of combining processes instead of one process and a variable to deal with intergenerational equity one may choose objectives various constraints or a combination of both for regional models one may consider various types of conditions on cross boundary flows and external factors of regional processes multiple use can be modelled as an intermediate stage between single resource models with a partial view and complex models with a general view sensitivity probability and scenario analyses can be used to deal partially with the various types of long term uncertainty although this remains difficult for the very important class of unexpected events or catastrophes such surprises can at best be turned into risk by scenario analyses and examination of dynamic behaviour of the system as a whole

estimation and control of spanish energy related co2 emissions an input output approach this article uses input output methods to obtain the energy related co2 intensities for the spanish economy in 1992 based on those intensities it yields a structural decomposition of spanish energy related co2 emissions and an estimation of the price effects of several hypothetical carbon taxes levied on fossil fuel consumption these results are related to the ongoing discussion within eu circles and member states about the consequences of carbon energy taxes and to the simulated effects of such taxes in various countries the paper also responds to the lack of reliable disaggregated data on spanish co2 emissions and to the growing awareness on the limited effectiveness of spanish climate change policies

shrouded attributes consumer myopia and information suppression in competitive markets bayesian consumers infer that hidden add on prices e g the cost of ink for a printer are likely to be high prices if consumers are bayesian firms will not shroud information in equilibrium however shrouding may occur in an economy with some myopic or unaware consumers such shrouding creates an inefficiency which firms may have an incentive to eliminate by educating their competitors customers however if add ons have close substitutes a curse of debiasing arises and firms will not be able to profitably debias consumers by unshrouding add ons in equilibrium two kinds of exploitation coexist optimizing firms exploit myopic consumers through marketing schemes that shroud high priced add ons in turn sophisticated consumers exploit these marketing schemes it is not possible to profitably drive away the business of sophisticates it is also not possible to profitably lure either myopes or sophisticates to nonexploitative firms we show that informational shrouding flourishes even in highly competitive markets even in markets with costless advertising and even when the shrouding generates allocational inefficiencies

trade and the environment from a southern perspective the relationship between free trade and the environment is one of the main issues of contention between environmental and ecological economics environmental economics assumes a positive relationship between free trade economic growth and environmental policies environmental externalities may cause important damage however trade is not to be blamed for this instead the fault lies with policy inadequacies at the national level on the other hand some ecological economists criticise the assumptions of environmental economics especially the immobility of production factors and the positive correlation between income and environmental quality they plead for measures to prevent deterioration of northern environmental standards in a race to the bottom due to ecological dumping from the south in this paper we argue that neither environmental economics nor northern ecological economics take into account the structural conditions determining the international trade system based on some new empirical evidence on material flows we stress the notion of environmental cost shifting if physical and political ecology perspectives are adopted a southern approach to the trade and environment issue may arise 2001 elsevier science b v all rights reserved

optimal sin taxes abstract we investigate sin taxes on unhealthy items such as fatty foods that people may by their own reckoning consume too much of we employ a standard optimal taxation framework but replace the standard assumption that all consumers have 100 self control with an assumption that some consumers may have some degree of self control problems we show that imposing taxes on unhealthy items and returning the proceeds to consumers can generally improve total social surplus because such taxes counteract over consumption by consumers with self control problems while at the same time they naturally redistribute income to consumers with no self control problems who consume less such taxes can even create pareto improvements finally we demonstrate with some simple numerical examples that even if the population exhibits relatively few self control problems optimal taxes can still be large

an institutional analysis of methods for environmental appraisal abstract this paper focuses on a set of issues when choosing between methods for environmental appraisal approaches like cost benefit analysis contingent valuation multicriteria analysis and deliberative methods are based on very different assumptions concerning the characteristics of environmental resources the capacities of the individuals involved and the role the methods play in framing the process the present paper views environmental appraisal methods as institutional structures they are seen as rules concerning a who should participate and in which capacity b what is considered data and which form data should take and c rules about how a conclusion is reached specifically the choice of method defines the logic of the appraisal process and next influences the output while cost benefit analysis is based on the assumption of individual rationality deliberative methods assume that individuals can act according to social rationality the first part of the paper is devoted to clarifying what institutions are and their role in the valuation process second the main features of environmental or ecosystem services and the demands they raise for decision making are described a general framework for evaluating appraisal methods is then developed finally this structure is elaborated in more detail as a basis for deciding over the choices of methods in the case of evaluating ecosystem services a set of unresolved issues are identified especially related to how the choice of appraisal methods themselves should be instituted

multicriteria decision analysis and environmental economics an approximation abstract a multicriteria approach to address basic problems in environmental economics is proposed in this paper the methodology is underpinned by the wellknown multicriteria method called compromise programming together with some recent results relating the compromise sets with the traditional optimisation of the utility functions to illustrate the proposed methodology the following two cases are suggested 1 the reconciliation between economic environmental as well as recreational objectives inherent to the management of an environmental asset such as forestry system and 2 its application to the appraisal of environmental improvements or damages when nonmonetary objectives are involved

a consumption based approach to carbon emission accounting sectoral differences and environmental benefits in recent years there has been growing concern about the emission trade balances of countries this is due to the fact that countries with an open economy are active players in international trade trade is not only a major factor in forging a country s economic structure but contributes to the movement of embodied emissions beyond country borders this issue is especially relevant from the carbon accounting policy and domestic production perspective as it is known that the production based principle is employed in the kyoto agreement the research described herein was designed to reveal the interdependence of countries on international trade and the corresponding embodied emissions both on national and on sectoral level and to illustrate the significance of the consumption based emission accounting it is presented here to what extent a consumption based accounting would change the present system based on production based accounting and allocation the relationship of co2 emission embodied in exports and embodied in imports is analysed here international trade can blur the responsibility for the ecological effects of production and consumption and it can lengthen the link between consumption and its consequences input output models are used in the methodology as they provide an appropriate framework for climate change accounting the analysis comprises an international comparative study of four european countries germany the united kingdom the netherlands and hungary with extended trading activities and carbon emissions moving from a production based approach in climate policy to a consumption based principle and allocation approach would help to increase the efficiency of emission reductions and would force countries to rethink their trading activities in order to decrease the environmental load of production activities the results of this study show that it is important to distinguish between the two emission accounting approaches both on the global and the local level

a goal programming model for environmental policy analysis application to spain abstract sustainable development has become an important part of international and national approaches to integrate economic environmental social and ethical considerations so that a good quality of life can be enjoyed by current and future generations for as long as possible however nowadays sustainable development is threatened by industrial pollution emissions which cause serious environmental problems due to a lack of adequate quantitative models for environmental policy analysis there is a strong need for analytical models in order to know the effects of environmental policies in the present paper a goal programming model based on an environmental input output linear programming model is developed and applied to the spanish economy the model combines relations between economic energy social and environmental effects providing valuable information for policy makers in order to define and examine the different goals that must be implemented to reach sustainability

evidence on macroeconomic complementarities this paper provides empirical evidence on macroeconomic complementarities a restriction on the nature of interaction between individuals in a multiagent setting these models imply that activities across agents will be positively correlated that discrete decisions will be synchronized and that disturbances will be magnified and propagated the paper shows that these implications are consistent with aggregate observations as well as some microeconomic evidence further looking at certain historical episodes such as the national industrial recovery act as well as seasonal fluctuations provides additional support for models with macroeconomic complementarities copyright 1996 by mit press

developing a sustainability framework for the assessment of bioenergy systems the potential for biomass to contribute to energy supply in a low carbon economy is well recognised however for the sector to contribute fully to sustainable development in the uk specific exploitation routes must meet the three sets of criteria usually recognised as representing the tests for sustainability economic viability in the market and fiscal framework within which the supply chain operates environmental performance including but not limited to low carbon dioxide emissions over the complete fuel cycle and social acceptability with the benefits of using biomass recognised as outweighing any negative social impacts this paper describes an approach to developing a methodology to establish a sustainability framework for the assessment of bioenergy systems to provide practical advice for policy makers planners and the bioenergy industry and thus to support policy development and bioenergy deployment at different scales the approach uses multi criteria decision analysis mcda and decision conferencing to explore how such a process is able to integrate and reconcile the interests and concerns of diverse stakeholder groups

the shallow or the deep ecological economics movement ecological economics and its policy recommendations have become overwhelmed by economic valuation shadow pricing sustainability measures and squeezing nature into the commodity boxes of goods services and capital in order to make it part of mainstream economic financial and banking discourses there are deeper concerns which touch upon the understanding of humanity in its various social psychological political and ethical facets the relationship with nature proposed by the ecological economics movement has the potential to be far reaching however this is not the picture portrayed by surveying the amassed body of articles from this journal or by many of those claiming affiliation a shallow movement allied to a business as usual politics and economy has become dominant and imposes its preoccupation with mainstream economic concepts and values if instead ecological economists choose a path deep into the world of interdisciplinary endeavour they will need to be prepared to transform themselves and society the implications go far beyond the pragmatic use of magic numbers to convince politicians and the public that ecology still has something relevant to say in the 21st century author s abstract

economic instruments for environmental regulation our knowledge about economic incentive approaches to pollution control has grown rapidly in the two decades in which they have received serious analytical attention not only have the theoretical models become more focused and the empirical work more detailed but we have now had over a decade of experience with emissions trading in the u s and emission charges in europe as the world community becomes increasingly conscious of both the need to tighten environmental controls and the local economic perils associated with tighter controls in a highly competitive global marketplace it seems a propitious time to stand back and to organize what we have learned about this practical and promising approach to pollution control that may be especially relevant to current circumstances this paper draws upon economic theory empirical studies and actual experience with implementation to provide a brief overview of some of the major lessons we have learned about two economic incentive approaches emissions tradi copyright 1990 by oxford university press

dynamic complementarities a quantitative analysis abstract this paper considers the importance of dynamic complementarities as an endogenous source of propagation in a dynamic stochastic economy dynamic complementarities link the stocks of human and organizational capital which are influenced by past levels of economic activity to current levels of productivity we supplement an otherwise standard dynamic business cycle model with both contemporaneous and dynamic complementarities the model is calibrated using estimates of these effects from both micro and aggregate data our quantitative analysis identifies empirically relevant dynamic complementarities as a source of propagation for both technology and taste shocks

quasi hyperbolic discounting and retirement abstract some people have self control problems regularly this paper adds endogenous retirement to laibson s quasi hyperbolic discounting savings model quarterly journal of economics 112 1997 443 477 earlier selves think that the deciding self tends to retire too early and may save less to induce later retirement still earlier selves may think the pre retirement self does this too much saving more to induce early retirement the consumption pattern may be different from that with exponential discounting other observational non equivalence includes the impact of changing mandatory retirement rules or work incentives on savings and a possibly negative marginal propensity to consume out of increased future earnings naive agents are briefly considered

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

a participatory approach to sustainable energy strategy development in a carbon intensive jurisdiction the case of nova scotia the need for governments to reduce the exposure of energy consumers to future increases in fossil fuel prices places urgent pressure on policy makers to deliver fundamental transformations in energy strategies particularly in jurisdictions with high dependency on fossil fuel sources dorian et al 2006 this transformation is unlikely without a high level of stakeholder engagement in the policy development process this paper describes two policy development processes recently undertaken in nova scotia in which the inclusion of stakeholder views was central to the approach the first delivered a new institutional framework for electricity energy efficiency involving the inception of an independent performance based administrator the second required the delivery of a strategy to significantly increase renewable energy generation in the province it involved recommendations for changes in institutional arrangements financial incentives and technological options this process was followed by new commitments to renewable energy developments new infrastructure for the importation of hydro electricity and the announcement of fits for ocean energy in both cases recommendations were made by an independent academic institution and the government responded directly to a majority of recommendations the paper concludes with a discussion of lessons learned and the implications for future energy policy making in carbon intensive jurisdictions

participative multi criteria analysis for the evaluation of water governance alternatives a case in the costa del sol malaga this paper presents the results of a participatory multi criteria evaluation of urban water supply alternatives in costa del sol occidental in malaga spain multi criteria and social research techniques were combined relying on social actors involvement throughout the research work the paper documents that participatory processes allowed to unveil framings perspectives values and interests as well as understanding of the social and institutional context in which the waters are governed the deployment of this methodological approach has in this case provided an extended diagnosis which was the starting point to explore non a priori foreseen management alternatives by the researchers the methodological approach proved useful for problem structuring in a collective flexible and iterative way unveiling existing water management conflicts and their motivations and improving the quality and effectiveness of the information exchange and the reflection process among social actors even if the whole process developed in a research setting rather than in a policy for real one participatory multi criteria evaluation could in this case contribute to identify policy options that could be better defended before all the social actors including the general public thus attempting to achieve shared ground the paper suggests some methodological considerations for applying participatory multi criteria evaluation based on the outcomes of the case study application

degrowth initiatives in the urban water sector a social multi criteria evaluation of non conventional water alternatives in metropolitan barcelona abstract debates on degrowth have mainly focused on theoretical issues specially around the unsustainability of the current economic model based on growth along those lines some scholars have dealt with the opportunities and barriers to voluntary social action for degrowth at a general level notwithstanding the key importance of such debates we argue that local strategies to move towards degrowth are still to be explored departing from the specific case of water in this paper we interrogate the compatibility of non conventional centralised and decentralised water supply technologies desalination reclaimed water reuse greywater reuse and rainwater harvesting with degrowth principles taking as a case study the metropolitan area of barcelona spain a social multi criteria evaluation has been performed to explore the feasibility desirability and acceptability of both models the paper aims to explore the pros and cons of the different water alternatives in two different and hypothetic societies one based on growth business as usual and one based on degrowth the technical analysis reveals that rainwater harvesting and reclaimed water reuse are the most preferred alternatives from a degrowth perspective while reclaimed water reuse and desalination are the most preferred alternatives from a growth perspective the social multi criteria analysis also serves to unveil which social actors may favour or block the adoption of each alternative notwithstanding that most social groups see desalination as the least desired option this is the hegemonic non conventional source in spain which evidences the prevalence of growth discourses in water management local decision makers city council managers and environmental groups clearly opt for the promotion of rainwater harvesting and as a result they appear as potential allies to promote degrowth in water consumption the social multi criteria evaluation helps to elucidate the main challenges that need to be addressed in the pursuit of a more sustainable and equitable water management

on measuring the welfare cost of business cycles lucas 1987 argues that the gain from eliminating aggregate fluctuations is trivial following lucas a number of researchers have altered assumptions on preferences and found that the gain from eliminating business cycles are potentially very large however in these exercises little discipline is placed on preference parameters this paper estimates the welfare cost of business cycles allowing for potential time non separabilities in preferences where discipline is placed on the choice of preference parameters by requiring that the preferences be consistent with observed fluctuations in a model of business cycles that is a theoretical real business cycle world is constructed and the representative agent is then placed in this world the agent responds optimally to exogenous shocks given the frictions in the economy the agent s preference parameters along with other structural parameters are estimated using a bayesian procedure involving markov chain monte carlo methods two main results emerge from the paper first the form for the time non separability estimated in this paper is very different than the forms suggested and used elsewhere in the literature second the welfare cost of business cycles is close to lucas s estimate

five capital impact assessment appraisal framework based on theory of sustainable well being abstract this paper sets out to formulate an appraisal approach in context with sustainable development in conventional project appraisal such as energy undertakings most emphasis is placed on financial flows and rate of return on infrastructure investments although current greenhouse gas emissions are estimated to pose large costs on future generations these emissions are generally not estimated as part of the investment cost other public goods may also be omitted because their value is not recognized we review conventional cost benefit assessment and propose a new broader evaluation this new evaluation approach is based on the theory that five capital value types support long term well being rather than economic growth alone the theory states that humans depend on the size of stocks and flows from natural manufactured human social and financial capital we describe the five capitals to illustrate the value categories and outline an approach to evaluate all these in the context of energy development

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

in search of substantive economics comparing today s two major socio metabolic approaches to the economy mefa and musiasem ecological economics is largely about the substantive in kind study of the economy as opposed to a purely formal economic analysis in money following kapp polanyi and others this article argues that substantive economics is interested in the biophysical and politico institutional structure of the economy rather than in correct prices within a particular axiomatic conformity as in formal economics after outlining the history of the substantive vs formal dichotomy we point out that socio metabolic analyses are ecological economics most significant contribution towards substantive economics the core of this article then compares what could be today s two best candidates for offering a distinctive foundation to ecological economics as substantive economics material and energy flows analyses mefa and multi scale integrated analyses of societal and ecosystem metabolism musiasem while mefa is more easily comparative and historical musiasem is more integrative and comprehensive yet we also argue that socio metabolic analyses represent one of the three pillars of substantive economics and that both mefa and musiasem are still weak in integrating the politico institutional structure second pillar and a theory of needs third pillar if such an integration was done ecological economics would be in a position to offer a full fledge alternative substantive economic theory

flows funds and the complexity of deprivation using concepts from ecological economics for the study of poverty abstract poverty has been increasingly conceptualized as being multidimensional involving deprivation in many dimensions of life this paper discusses issues and implications of multidimensional poverty by adopting concepts commonly used in ecological economics in particular poverty is approached as an irreducible complex phenomenon for which many legitimate but non equivalent descriptions exist issues of social and technical incommensurability are illustrated for different meanings and measurement types of poverty georgescu roegen s flow fund framework is interpreted informed by the capability approach of amartya sen the paper argues that a predominant focus on flows as a proxy to analyze poverty represents rather a short term perspective on access to satisfiers to fulfill particular needs contrary to that focusing on valued funds may provide useful information for the analysis of capabilities that persons and societies might pursue in the long term furthermore it is argued that strong poverty alleviation needs to adopt analytical tools that can deal with non trade off cases improvements in one poverty dimension cannot always compensate for the deterioration of other poverties this implies to rethink the usefulness of aggregate multidimensional poverty indices as well as the predominant use of income measures

a credit score system for socially responsible lending ethical banking microfinance institutions or certain credit cooperatives among others grant socially responsible loans this paper presents a credit score system for them the model evaluates social and financial aspects of the borrower the financial aspects are evaluated under the conventional banking framework by analysing accounting statements and financial projections the social aspects try to quantify the loan impact on the achievement of millennium development goals such as employment education environment health or community impact the social credit score model should incorporate the lender s know how and should also be coherent with its mission this is done using multi criteria decision making mcdm the paper illustrates a real case a loan application by a social entrepreneur presented to a socially responsible lender the decision support system not only produces a score but also reveals strengths and weaknesses of the application

historical roots for ecological economics biophysical versus allocative approaches abstract a number of economists today are aware that the results of their science are more or less at variance with concrete fact and are alive to the necessity of perfecting it they go wrong rather in their choice of means to that end they try obstinately to get from their science alone the materials they know are needed for a closer approximation to fact whereas they should resort to other sciences and go into them thoroughly not just incidentally for their bearing on the given economic problem until economic science is much farther advanced economic principles are less important to the economists than the reciprocal bearings of the results of economics and the results of the other social sciences many economists are paying no attention to such interrelations for mastery of them is a long and fatiguing task requiring an extensive knowledge of facts whereas anyone with a little imagination a pen and a few reams of paper can relieve himself of a chat on principles pareto 1935 para 2022

pricing the ecosystem and taxing ecosystem services a general equilibrium approach abstract in an integrated dynamic general equilibrium model of the economy and the ecosystem humans and other species compete for land and prey biomass each submodel exhibits a price driven competitive allocation mechanism and the endogenously determined habitat is either openly accessible or privately owned in both scenarios specific corrective taxes or subsidies are needed to internalize ecosystem externalities an open access habitat causes additional inefficiencies through diverging prices for biomass and land in both subsystems values of all ecosystem components are determined in an efficient steady state clarifying the role and the interplay of ecosystem prices and economic prices

a regional dynamic general equilibrium model of alternative climate change strategies outcomes and noncooperative equilibria this study finds that cooperative policies show much higher levels of emissions reductions than do noncooperative strategies that there are substantial differences in the levels of controls in both the cooperative and the noncooperative policies among different countries and that high income countries may be the major losers from cooperation jel h41 q4 q2 q20

life cycle consumption and hyperbolic discount functions abstract studies of animal and human behavior suggest that discount functions are approximately hyperbolic ainslie picoeconomics 1992 hyperbolic models explain a wide range of empirical anomalies including 1 missing precautionary savings effects 2 incongruence between the elasticity of intertemporal substitution and the inverse of the coefficient of relative risk aversion 3 consumption discontinuities at retirement 4 variation in patience over the life cycle 5 consumer self reports of undersaving 6 disproportionate retirement accumulation in illiquid assets 7 asset specific marginal propensities to consume and 8 declining national savings rates in developed countries hyperbolic models also provide a new framework for analyzing the welfare gains that come from pro saving policies like social security and tax deferred retirement accounts

closely competing firms and price adjustment some findings from an online marketplace we investigate retailers price setting behavior using a unique dataset containing by the second records of prices offered by closely competing retailers on a major japanese price comparison website first we find that when the average price of a product across retailers falls rapidly the frequency of price adjustments increases and the size of price adjustments becomes larger second we find positive autocorrelation in the frequency of price adjustments implying that there tends to be clustering where price adjustments occur in succession in contrast there is no such autocorrelation in the size of price adjustments these two findings indicate that the behavior of competing retailers is characterized by state dependent pricing rather than time dependent pricing

the liquidity effect and money demand abstract i suggest a liquidity effect model in which financial intermediation costs are determined by aggregate economic activity an expansionary monetary shock leads to a persistent contraction in the loan deposit rate spread a persistent liquidity effect and a persistent real expansion a feature of this expansion is that nominal prices respond sluggishly to monetary shocks as an equilibrium outcome

factor demand linkages technology shocks and the business cycle abstract this paper argues that factor demand linkages can be important for the transmission of both sectoral and aggregate shocks we show this using a panel of highly disaggregated manufacturing sectors together with sectoral structural vars when sectoral interactions are explicitly accounted for a contemporaneous technology shock to all manufacturing sectors implies a positive response in both output and hours at the aggregate level otherwise there is a negative correlation as in much of the existing literature furthermore we find that technology shocks are important drivers of the business cycle

seasonal solow residuals and christmas a case for labor hoarding and increasing returns in aggregate unadjusted data measured solow residuals exhibit large seasonal variations total factor productivity grows rapidly in the fourth quarter at an annual rate of 16 percent and regresses sharply in the first quarter at an annual rate of 24 percent how much of the total seasonal variation in the measured solow residual can be explained by christmas the answer to this question is surprising with increasing returns and time varying labor effort christmas is sufficient to explain the seasonal variation in the solow residual consumption average productivity and output in all four quarters our analysis of seasonally unadjusted data uncovers important roles for labor hoarding and increasing returns that are difficult to identify in adjusted data prescott 1986 has argued that the variability of solow s residual is a reasonable estimate of the variability of exogenous technology shocks when solow s residual is measured using seasonally unadjusted data for the postwar u s economy it exhibits large seasonal variations growing rapidly in the fourth quarter at an annual rate of 16 percent and falling sharply in the first quarter at an annual rate of 24 percent this paper starts from the premise that it is implausible to attribute seasonal variation of this magnitude to changes in the state of technology we present a model in which all seasonal fluctuations arise from a single demand shift christmas this demand shift together with misspecification of the traditional production function leads to large seasonal variation in the solow residual we consider two candidates for misspecification labor hoarding and external increasing returns to scale even when technological growth is aseasonal either candidate in isolation can induce spurious seasonality in the solow residual our general equilibrium analysis indicates that 1 the economy s seasonal patterns in all four quarters may be a response simply to a fourth quarter consumption demand shift and 2 a combination of labor hoarding and external increasing returns is important for replicating these patterns in aggregate quantity variables for the postwar u s economy since our analysis identifies important roles for labor hoarding and increasing returns these results have implications for nonseasonal macroeconomic models indeed our analysis im

what have macroeconomists learned about business cycles from the study of seasonal cycles this paper argues that analysis of seasonal fluctuations can shed light on the nature of business cycle fluctuations the fundamental reason is that in many instances identifying restrictions about seasonal fluctuations are more believable than analogous restrictions about nonseasonal fluctuations the authors show that seasonal fluctuations provide good examples of preference shifts and synergistic equilibria they also find evidence against production smoothing and in favor of unmeasured variation in labor and capital utilization in some industries capacity constraints appear to bind copyright 1996 by mit press

a social and environmental approach to microfinance credit scoring microfinance institutions provide loans to low income individuals their credit scoring systems if they exist are strictly financial although many institutions consider the social and environmental impact of their loans they do not incorporate formal systems to estimate these social and environmental impacts this paper proposes that their creditworthiness evaluations should be coherent with their social mission and accordingly should estimate the social and environmental impact of microcredit thus a decision support system to facilitate microcredit granting is proposed using a multicriteria evaluation the assessment of social impact is performed by calculating the social net present value the system captures credit officers experience and addresses incomplete and intangible information the model has been tested in a microfinance institution the paper shows how a small institution can include social and environmental issues in its decision making systems to evaluate credit applications a gap in the preferences was found between members of the board who are socially driven and managers and credit officers who are financially drifted this mission drift was corrected the approach followed contributed to creating a culture of social and environmental assessment within the institution especially among credit officers thereby translating microfinance institutions social mission into numbers

ecological thresholds a survey abstract the existence of ecological discontinuities and thresholds has been recognised by ecological economics as a key feature to take into account in the study of environment economy interactions this paper reviews some theoretical developments and empirical studies dealing with ecological phenomena involving non linear dynamics the literature about this issue reveals that there is abundant evidence of discontinuities and threshold effects as the consequence of human perturbations on ecological systems however due to the complexities involved the predictive capacity of ecology is limited and large uncertainties still remain

does ecological economics have a future contradiction and reinvention in the age of climate change abstract this paper addresses the role of neoclassical methodologies in ecological economics and the contradictions these methodologies pose to the field s critical founding principles we first consider robert costanza s treatment of nicholas stern s global deal and then survey climate change related articles published in this journal over the past five years this survey reveals how mainstream neoclassical methodologies dominate discourse and do so by marginalizing more critical political economy analyses this situation imperils the field s founding vision of a no growth steady state it also fails to address the related growth dynamics of capitalism without such a critical treatment the field s formal embrace of methodological pluralism actually entails an ideological empiricism that renders ecological economics theoretically incoherent this situation undermines the field s historical promise as an alternative economic paradigm ecological economics now faces a problematic future its survival in a form faithful to its founding vision will require an explicit choice to address its internal contradictions and reinvent itself in ways relevant to our contemporary context without such a choice ecological economics will likely succumb to an implicit acceptance of the hegemony of mainstream economic methodologies and their pro growth imperatives

the challenge of measuring biofuel sustainability a stakeholder driven approach applied to the french case measuring biofuel sustainability requires dealing with a wide variety of complex and conflicting values at stake consequently the biofuel capacity to contribute to one specific value cannot lead to any absolute conclusion about the overall sustainability of biofuel the scope of the sustainability concept may vary depending on individuals preferences the time scale and the geographical region based on the 5 pillars sustainability concept that includes social economic environmental legal and cultural considerations the present study proposes to assess several biofuel sustainability options for france by 2030 through a stakeholder driven approach rather than seeking to reach a consensus our approach allows us to capture the wide diversity of stakeholders perspectives and preferences french stakeholders perceive 22 different sustainability criteria for biofuels with a very low level of agreement between the different segments of professions feedstock producers biofuel producers refining industry fuel distributors car manufacturers end users government and ngos in order to operationalize the sustainability assessment a set of indicators has been identified with stakeholders that allows us to measure the capacity of biofuels to fulfill each of their criteria seventeen biofuel options were assessed with regards to economic social environmental cultural and legal considerations allowing the identification of the strengths and weaknesses of each biofuel

geographical variations in expenditure of learning disability services in england this article investigates the determinants of local authority learning disability ld expenditure in england it adopts a reduced form of demand and supply model extended to account for possible interdependence between municipalities risk factors such as people aged under 14 mortality rate and lone parents seem to play an important role in explaining geographical variation of spending further labour municipalities on average allocate lower resources on ld than do other political parties finally results corroborate recent findings in economics that authorities interact with each other when allocating public resources

changing industrial structure to reduce carbon dioxide emissions a chinese application abstract increasing concern about carbon dioxide co2 emission reduction demands knowledge about the production structure of an economy information on productive linkages yields insight about forward and backward emission effects associated with sectoral inputs and outputs and serves as an essential starting point to identify the optimised industrial structure under the constraint of co2 emission this paper proposes a combined linkage analysis and multi objective programming approach to identify the key co2 emission sectors and the optimised production structure with respect to emission reduction target as a demonstration the proposed approach is applied to data from china in 2007 the result shows that to reduce co2 emissions from 5707 16 to 5452 12 million tonnes china needs to change its industrial structure by focussing on industrial groups as defined by linkage characteristics which would lead to a subsequent gdp decrease of 82 59 billion yuan from a policy standpoint the analytical techniques described in this paper can provide valuable information for planners and decision makers to formulate feasible and practical industrial polices with implications for co2 emissions

choice and procrastination author s o donoghue ted rabin matthew abstract recent models of procrastination due to self control problems assume that a procrastinator considers just one option and is unaware of her self control problems we develop a model where a person chooses from a menu of options and is partially aware of her self control problems this menu model replicates earlier results and generates new ones a person might forego completing an attractive option because she plans to complete a more attractive but never to be completed option hence providing a non procrastinator additional options can induce procrastination and a person may procrastinate worse pursuing important goals than unimportant ones

weak comparability of values as a foundation for ecological economics the main argument of this paper is that weak comparability of values should be seen as one characteristic feature of ecological economics the formal properties of the concepts of strong comparability implying strong or weak commensurability and weak comparability implying incommensurability will be clarified multicriteria evaluation offers the methodological and mathematical tools to operationalize the concept of incommensurability at both macro and micro levels of analysis the concept of incommensurability of values already has a long tradition in economics moreover we will show that analytic philosophy theories of complexity post normal science and the recent theories of rationality lead with different trajectories to a non algorithmic approach which in our view could be implemented by some forms of multicriteria evaluation 1998 elsevier science b v all rights reserved

a review and comparison of tests of cross section independence in panels abstract in this paper we review and compare diagnostic tests of cross section independence in the disturbances of panel regression models we examine tests based on the sample pairwise correlation coefficient or on its transformations and tests based on the theory of spacings the ultimate goal is to shed some light on the appropriate use of existing diagnostic tests for cross equation error correlation our discussion is supported by means of a set of monte carlo experiments and a small empirical study on health results show that tests based on the average of pairwise correlation coefficients work well when the alternative hypothesis is a factor model with non zero mean loadings tests based on spacings are powerful in identifying various forms of strong cross section dependence but have low power when they are used to capture spatial correlation

the impact of demographic change on energy use and greenhouse gas emissions in germany abstract this paper estimates the impact of demographic change on energy use and greenhouse gas emissions in germany since old people display different consumption patterns than young people an increase in the proportion of old people affects overall consumption patterns micro data from a household survey are used to identify age specific consumption patterns and to project the impact of demographic change on the structure of total consumption expenditure up to the year 2030 the resulting final demand vectors are entered into an environmental input output model which allows the calculation of sectoral production energy use and greenhouse gas emissions the model results suggest that until 2030 demographic change raises the share of methane in total greenhouse gas emissions and does not contribute to reducing energy use and greenhouse gas emissions in germany the model is also used to explore the effects of redistributing income between age groups and a policy induced switch from motor vehicle use to public transport

trade liberalization economic specialization and the environment abstract a great deal has been written and a great deal of debate has raged on the effects of international trade and trade liberalization on the environment given that it is only recently that the general agreement on tariffs and trade has begun to address the interdependence of the international economy and the international environment in a systematic way it is likely that the debate will continue for quite some time it will be argued that the economic case for there being benign environmental consequences associated with trade liberalization is flawed in important ways this is due to statistical empirical and conceptual issues which affect the estimation of such effects moreover it will be argued that despite the intensity of the debate the effects of international trade on the environment have in fact only been addressed in an incidental manner rather the debate has concentrated on factors that may coexist with trade but not on the role of trade itself this has served to obscure the more fundamental environmental effects of trade liberalization through the homogenization and specialization of ecosystems

ecological pricing and economic efficiency abstract there is a need to accurately account for the contributions of environmental assets to the overall economy such accounting would permit policies that allow protection of important natural resources and aid the analytic process to determine an accurate basis for a sustainable economy the aim is to develop an accounting framework for ecology that is sufficiently consistent with the economic framework that the two can be fruitfully combined with appropriate definitions of the flows the two systems can be connected into a common framework no single measure of the system productivity and efficiency can be given for the combined system however until the ecosystem metabolism can be converted into economic terms this could be done with a series of economic valuation techniques ecological prices could then be estimated and a single measure of ecological economic output could be given with the net combined system input and output now in common terms a technical system efficiency measure can logically be proposed because human activity inevitably involves dissipation such emissions would now have a monetary price because such emissions are irrecoverable the total output of the combined system is greater than it is under the current definition giving rise to a technical system wide efficiency measure

exploiting naivete about self control in the credit market we develop a model of the credit market where competitive lenders oer long term contracts specifying a non linear schedule of possible repayment schedules to borrowers who may dier both in their taste for immediate gratication and their prior beliefs about that taste the equilibrium contract to a borrower with given beliefs is discontinuous it features an advantageous option involving fast repayment and a penalty for deviating and repaying later these predictions seem to resemble some salient features of many credit card and mortgage contracts for fully sophisticated borrowers the discontinuity acts as a commitment device and yields fast repayment but all other borrowers even those with an arbitrarily small amount of naivete end up delaying repayment despite the penalty and receive little benet from commitment furthermore because they believe they will repay early they underestimate the cost of credit and hence borrow too much non sophisticated borrowers cross subsidize sophisticated borrowers while sophisticated borrowers discipline rms by preventing very exploitative contracts we identify natural conditions under which the above results obtain even if

on the mechanics of migration decisions skill complementarities and endogenous price differentials abstract why are highly skilled workers more responsive than other workers to productivity differentials when taking migration decisions why do low skilled workers abandon rich regions this paper aims to answer these questions using skill complementarities and endogenous price differentials between rich and poor regions if the skill premium is increasing in the average level of human capital of a location the more skilled the workers are the stronger the economic incentives to migrate to the rich regions become in contrast the low skilled workers have an incentive to migrate to the poor regions to minimize their living costs

industrial output restriction and the kyoto protocol an input output approach with application to canada the objective of this paper is to assess the economic impacts of reducing greenhouse gas emissions by decreasing industrial output in canada to a level that will meet the target set out in the kyoto protocol the study uses an ecological economic input output model combining economic components valued in monetary terms with ecologic components ghg emissions expressed in physical terms economic and greenhouse gas emissions data for canada are computed in the same sectoral disaggregation three policy scenarios are considered the first one uses the direct emission coefficients to allocate the reduction in industrial output while the other two use the direct plus indirect emission coefficients in the first two scenarios the reduction in industrial sector output is allocated uniformly across sectors while it is allocated to the 12 largest emitting industries in the last one the estimated impacts indicate that the results vary with the different allocation methods the third policy scenario allocation to the 12 largest emitting sectors is the most cost effective of the three as the impacts of the kyoto protocol reduces gross domestic product by 3 1 compared to 24 and 8 1 in the first two scenarios computed economic costs should be considered as upper bounds because the model assumes immediate adjustment to the kyoto protocol and because flexibility mechanisms are not incorporated the resulting upper bound impact of the third scenario may seem to contradict those who claim that the kyoto protocol would place an unbearable burden on the canadian economy c 2008 elsevier b v all rights reserved

contracting with diversely naive agents in standard contract theoretic models the underlying assumption is that agent types differ in their preference or cost parameters and the principal s objective is to design contracts in order to screen this type we study a contract theoretic model in which the heterogeneity among agent types is of a cognitive nature in our model the agent has dynamically inconsistent preferences agent types differ only in their degree of sophistication that is their ability to forecast the change in their future tastes we fully characterize the menu of contracts which the principal offers in order to screen the agent s sophistication the menu does not exclude any type it provides a perfect commitment device for relatively sophisticated types and exploitative contracts which involve speculation with relatively naive types more naive types are more heavily exploited and generate a greater profit for the principal our results allow us to interpret real life contractual arrangements in a variety of industries

complementarity of socio economic and emergy evaluation of agricultural production systems the case of slovenian dairy sector agriculture is a complex system in which the economic principles of production are directly intertwined with its biological and ecological characteristics the paper investigates synergetic potentials of multiple criteria and multiple perspective evaluation of agricultural activity through a study of the dairy sector in slovenia socio economic and emergy evaluation was performed on nine farm types formulated to represent the diversity of the country s dairy sector the results indicate larger discrepancies in the performance of the farm types when defined by socio economic or emergy based indicators standard socio economic evaluation favours larger conventional systems that are cost efficient and financially independent emergy analysis however favours less productive organic farms which show greater ability to exploit free local resources and produce less stress on the local environment socio economic and emergy indicators show that small conventional farm types are the poorest performers overall analysis of emergy flows reveals for all farm types a high dependency on the wider socio economic system suggesting that within the current economic system agriculture itself has little ability to affect its sustainability the paper suggests a complementarity in the evaluation approaches their joint application can improve the quality of the decision making process in various stages of planning in agriculture and land use

linking economic and ecological models for a marine ecosystem increasingly economists and ecologists have begun to recognize the value to public policy of combining information and results from each discipline into multidisciplinary studies here we present a methodological approach that links economic and ecological analyses we develop an economic ecological model by merging an input output model of a coastal economy with a model of a marine food web we describe distinct linear system sub models of the economy and the ecosystem and we develop a method for linking the two our method extends the work of earlier researchers by incorporating an ecosystem matrix into resource multipliers and by showing how these multipliers may be calculated we present a numerical example for the new england region using coastal economic and marine ecological data from the region for a restricted set of industry sectors and food web trophic levels we calculate resource multipliers for the example and we simulate the economic impacts of changes in primary production in the ecosystem on final demands for fishery products the results illustrate the effects of incorporating the impacts of habitat destruction and ecosystem structure on resource multipliers our approach can be extended to incorporate the full range of sectors in the economy and trophic levels in a linked ecosystem 2003 elsevier b v all rights reserved

the value base of water governance a multi disciplinary perspective some scholars promote water governance as a normative concept to improve water resources management globally while others conceive of it as an analytical term to describe the processes systems and institutions around the management of water resources and water supply critics often highlight how specific water governance scenarios fail to deliver socially desirable outcomes such as social justice or environmental sustainability while water governance is often perceived as a technical matter its conceptual and practical components are in fact based on multiple values that nonetheless often remain implicit the present paper seeks to uncover this value base and discusses existing research on values from multiple perspectives using material from economics philosophy psychology and other social sciences in different disciplines values can be understood as fundamental guiding principles governance related values or as values assigned to water resources together they shape complex relationships with water governance which from an analytical perspective is understood as a combination of policy politics and polity introducing a new conceptual framework this study seeks to provide a theoretical foundation for empirical research on water governance processes and conflicts

investigating the sustainability of renewable energy an empirical analysis of european union countries using a hybrid of projection pursuit fuzzy clustering model and accelerated genetic algorithm based on real coding abstract renewable energy sustainability plays a significant role in ensuring energy security improving environment and promoting sustainable development of economic and social this paper focuses on assessing and analyzing the sustainability and influencing factors of 27 eu countries renewable energy by dpsir four dimensional indicators system four sustainability dimensions of energy economy society and environment are considered and integrated to deal with the randomness and fuzziness of multi dimensional metadata and to conduct assessment without standard we develop a nonlinear multi factor assessment model projection pursuit fuzzy clustering model with accelerated genetic algorithm based on real coding the results show that the co2 emissions energy productivity non renewable energy emission intensity energy dependence electricity price and policy support are closer related to the renewable energy sustainability the strongest sustainability countries are denmark and sweden from the overall analysis time series analysis shows that general sustainable level is a wave of growth the geographical analysis shows that the countries with better sustainable development are mainly located in the central region showing a belt distribution from north to south the sustainability decreases from the middle to the sides

news shocks and the slope of the term structure of interest rates abstract we adopt a statistical approach to identify the shocks that explain most of the fluctuations of the slope of the term structure of interest rates we find that one shock can explain the majority of unpredictable movements in the slope impulse response functions lead us to interpret this shock as news about future total factor productivity tfp by showing that slope shocks are essentially tfp news shocks we provide a new explanation for the relationship between the slope and macroeconomic fundamentals our results also provide a new empirical benchmark for structural models at the intersection of macroeconomics and finance jel e23 e43 e52 g12 g14

policy incentives for switchgrass production using valuation of non market ecosystem services abstract this study presents a linear profit model with combined economic and environmental factors for a switchgrass for biofuels agricultural system in the southeastern u s the objectives are to establish conversion to switchgrass thresholds for various market prices and identify policy incentives that would ensure economic profit while also maximizing environmental benefits carbon sequestration displacement of fossil fuels and minimizing negative impacts global warming potential nitrate loss weighting factors are chosen to represent incentives and penalties by assigning value to the impacts with no other incentives switchgrass market prices of at least 51 and 58 dton would be needed in order to make a profitable switch from corn conservation reserve program crp lands and cotton respectively at a mid range offering of 50 dton feasible carbon credit prices of 3 8 23 per metric tonne co 2 e would incentivize conversion from corn crp or cotton respectively similarly a water quality penalty of 0 20 3 2 per kilogram no 3 n leached would incentivize the same conversions with resultant watershed improvement at a lower price of 30 dton switchgrass incentives based on valuation of ecosystem services begin to exceed feasible ranges of these valuations

non compensatory non linear composite indicators for ranking countries a defensible setting composite indicators or indexes are very common in economic and business statistics for benchmarking the mutual and relative progress of countries in a variety of policy domains such as industrial competitiveness sustainable development globalization and innovation the proliferation of the production of composite indicators by all the major international organizations is a clear symptom of their political importance and operational relevance in policy making as a consequence improvements in the way these indicators are constructed and used seem to be a very important research issue from both the theoretical and operational points of view this article aims at contributing to the improvement of the overall quality of composite indicators or indexes by looking at one of their technical weaknesses that is the aggregation convention used for their construction for this aim we build upon concepts coming from multi criteria decision analysis measurement theory and social choice we start from the

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

toward consilience between biology and economics the contribution of ecological economics abstract during its ten year history ecological economics has made a real difference in the way economists look at the natural world and in the way biologists look at the economy in this survey article we examine the contributions to the journal in terms of e o wilson s concept of consilience that is his argument that the methods and assumptions of any field of study should be consistent with the known and accepted facts in other disciplines in particular we examine the contributions of ecological economics to reconciling the economic theory of the consumer and producer with biophysical reality

targeting conservation efforts in the presence of threshold effects and ecosystem linkages abstract the prevailing federal policy of targeting conservation programs on the basis of physical criteria tends to ignore the threshold effect of conservation efforts and the correlation between alternative environmental benefits in this article we examine the extent to which conservation funds will be misallocated when threshold effects and correlated benefits are ignored we show that targeting conservation efforts based on physical criteria or political equity concerns may actually lead to the lowest possible benefits to society from conservation expenditure ignoring correlated benefits may lead not only to misallocation of conservation funds among watersheds but also to incorrect resources e g land streams being targeted for conservation the empirical analysis focuses on riparian habitat investments for salmon restoration in the pacific northwest we show that a large portion of conservation benefits would be lost when threshold effects and correlated benefits are ignored and argue that funds should be allocated so that the total value of environmental benefits is maximized not the total amount of resources protected

over savings and hyperbolic discounting abstract hyperbolic discounting models are widely seen as implying that consumers do not save enough in accordance with the observed low rates of savings of some households this paper qualifies this view by showing that hyperbolic consumers may oversave in the short run the result extends to uncertainty on future income and does not depend on whether preferences are present biased or future biased a generalized comparative statics analysis of self control is introduced and its relationship to the analysis of uncertainty on discount factors is emphasized

life insurance and life settlement markets with overconfident policyholders abstract we analyze how the life settlement market the secondary market for life insurance may affect consumer welfare in a dynamic equilibrium model of life insurance with one sided commitment and overconfident policyholders in our model policyholders may lapse their life insurance policies when they lose their bequest motives however they are overconfident in the sense that they may underestimate the probability of losing their bequest motives we show that in the competitive equilibrium without life settlement overconfident consumers will buy life insurance contracts with too much reclassification risk insurance for later periods the life settlement market can impose a limit on the extent to which primary insurers can exploit overconfident consumers we show that the life settlement market may increase the equilibrium consumer welfare of overconfident consumers when they are sufficiently vulnerable in the sense that they have a sufficiently large intertemporal elasticity of substitution of consumption our result is robust to alternative specifications where i insurers cannot observe the subjective or objective probability that policyholders will lose their bequest motives ii insurers can include health contingent cash surrender values csvs in the life insurance contract and iii policyholders underestimate their future mortality risk

a theory of intermediated investment with hyperbolic discounting investors abstract financial intermediaries may reduce welfare losses caused by hyperbolic discounting investors who may liquidate their investment prematurely when the liquidation cost is low in a competitive equilibrium sophisticated investors are offered contracts with perfect commitment and first best results are achieved naive investors are attracted by contracts that offer seemingly attractive returns in the long run but introduce discontinuous penalties for early withdrawal if the investor types are private information naive investors withdraw early and cross subsidize sophisticated investors when a secondary market for long term contracts opens for trading financial intermediaries are compelled to offer contracts that have more flexible withdrawal options with linear schemes and the welfare of naive investors is improved arbitrage free linear contracts allow for a unique term structure for interest rates that includes a premium for naivete solvency requirements may limit competition for contracts and result in positive profits banks that have capital are able to compete more aggressively which improves investor welfare

inferior products and profitable deception we analyse conditions facilitating profitable deception in a simple model of a competitive retail market firms selling homogenous products set anticipated prices that consumers understand and additional prices that naive consumers ignore unless revealed to them by a firm where we assume that there is a binding floor on the anticipated prices our main results establish that bad products those with lower social surplus than an alternative tend to be more reliably profitable than good products specifically 1 in a market with a single socially valuable product and sufficiently many firms a deceptive equilibrium in which firms hide additional prices does not exist and firms make zero profits but perversely 2 if the product is socially wasteful then a profitable deceptive equilibrium always exists furthermore 3 in a market with multiple products since a superior product both diverts sophisticated consumers and renders an inferior product socially wasteful in comparison it guarantees that firms can profitably sell the inferior product by deceiving consumers we apply our framework to the mutual fund and credit card markets arguing that it explains a number of empirical findings regarding these industries

the history of ecosystem services in economic theory and practice from early notions to markets and payment schemes article i nfo this paper reviews the historic development of the conceptualization of ecosystem services and examines critical landmarks in economic theory and practice with regard to the incorporation of ecosystem services into markets and payment schemes the review presented here suggests that the trend towards monetization and commodification of ecosystem services is partly the result of a slow move from the original economic conception of nature s benefits as use values in classical economics to their conceptualization in terms of exchange values in neoclassical economics the theory and practice of current ecosystem services science are examined inthelight ofthis historicaldevelopment from thisreview we conclude thatthefocus onmonetary valuation and payment schemes has contributed to attract political support for conservation but also to commodify a growing number of ecosystem services and to reproduce the neoclassical economics paradigm and the market logic to tackle environmental problems

dynamic multidimensional assessment of sustainability at the macro level the case of austria abstract this paper explores the issue of sustainability at the macro scale employing multi criteria decision aid mcda methods the incommensurability of values and the essentially multi dimensional and dynamic nature of sustainability challenge the use of composite measurement indices this determined the choice of mcda methods austria was chosen as a case study due to the wide availability of data especially on indicators of strong sustainability the structure of the multi criteria problem comprised the evolution of different sustainability dimensions over time the process for selecting criteria included a critical assessment of institutional sustainability agendas un eu and austrian government and theoretical recommendations after an assessment of mcda methods the naiade method demonstrated the most suitable properties for sustainability assessment the application of this outranking approach was undertaken in three separate settings long term from 1960 to 2003 medium term 1970 1995 and short term 1995 2003 with varying numbers of criteria the response of results to the addition of evaluating criteria and periods was tested the degree of credibility for accepting preference relations was also employed for sensitivity analysis according to the results of long term and medium term assessments especially in the weak sustainability setting sustainable progress is taking place in austria in the short term in the stronger sustainability setting and especially as the number of criteria increases more incomparable periods appear and trends are less determined moreover it is shown how results crucially depend on the methodological choices this is one of the first applications of the multi criteria tools to the dynamic analysis of sustainability at the macro scale
