an economic theory of self control the concept of self control is incorporated in a theory of individual intertemporal choice by modeling the individual as an organization the individual at a point in time is assumed to be both a farsighted planner and a myopic doer the resulting conflict is seen to be fundamentally similar to the agency conflict between the owners and managers of a firm both individuals and firms use the same techniques to mitigate the problems which the conflicts create this paper stresses the implications of this agency model and discusses as applications the effect of pensions on saving saving and the timing of income flows and individual discount rates

ecosystem services from eye opening metaphor to complexity blinder abstract what started as a humble metaphor to help us think about our relation to nature has become integral to how we are addressing the future of humanity and the course of biological evolution the metaphor of nature as a stock that provides a flow of services is insufficient for the difficulties we are in or the task ahead indeed combined with the mistaken presumption that we can analyze a global problem within a partial equilibrium economic framework and reach a new economy project by project without major institutional change the simplicity of the stock flow framework blinds us to the complexity of the human predicament the ecosystem services approach can be a part of a larger solution but its dominance in our characterization of our situation and the solution is blinding us to the ecological economic and political complexities of the challenges we actually face

employment based analysis an alternative methodology for project evaluation in developing regions with an application to agriculture in yucatan abstract governmental and non governmental organizations ngos in developing regions increasingly recognize the links between sustainable development and environmental protection for this reason environmental protection efforts in these regions increasingly include sustainable community development projects unlike most traditional large scale development projects the objective of such projects is to give local inhabitants sustainable economic alternatives to environmentally degrading activities rather than to maximize the flow of discounted net benefits the traditional method of project evaluation cost benefit analysis cba does not provide useful information regarding the meeting of such objectives the purpose of this paper is to introduce discuss and provide a brief example of employment based analysis eba as a means of project evaluation in developing countries in contrast to the cba approach of measuring a discounted flow of net benefits from economic options eba measures the number of jobs or population support provided by alternative activities using a given resource typically land over a given period of time eba better incorporates sustainability into project analysis by avoiding the use of discounting directly linking project success with environmental sustainability and penalizing economic activities that involve income inequality and income capital flight eba is particularly illuminating when applied to small scale sustainable development projects that are part of environmental conservation programs after a brief description of the methodology the motivation strengths and weaknesses of eba are discussed a simple application of eba and cba to alternative agricultural activities traditional farming improved farming and cattle ranching in yucatan mexico is then provided this analysis indicates that while cattle ranching has a higher benefit cost ratio both traditional and improved farming provide more population support and greater contributions to sustainability this example serves to highlight the potential benefits to using eba instead of or in conjunction with cba in developing regions along with highlighting some of the strengths and challenges of eba

the environmental social interface of sustainable development capabilities social capital institutions the social dimension has commonly been recognised as the weakest pillar of sustainable development notably when it comes to its analytical and theoretical underpinnings while increasing attention has lately been paid to social sustainability the interaction between the environmental and the social still remains a largely uncharted terrain nevertheless one can argue that the key challenges of sustainable development reside at the interfaces synergies and trade offs between its various dimensions this paper looks for preliminary ideas on frameworks for analysing the environmental social interface it first discusses the concept of sustainable development and the relations of the three dimensions of sustainability on the basis of the fundamental premises of neoinstitutional and ecological economics and briefly presents the bioeconomy model based on this conceptualisation of sustainable development it then goes on to analyse two popular ways of addressing the social dimension of sustainability namely the capability approach of amartya sen and the concept of social capital and discusses the potential of these as bases for the analysis of the environment social interaction the organisation for economic cooperation and development oecd environmental performance review epr programme is presented as an example of attempts to analyse the environmental social interface in practice the paper concludes by noting that a single framework for studying environmental social interface is neither feasible nor desirable it questions the usefulness of analysing only two dimensions of sustainability at a time and emphasises the need to situate the analysis in its context in particular it stresses the need to involve the potential users as well as to take into account the planned use of the analysis and the interactions between different levels of analysis and decision making capabilities and social capital can both be useful in structuring thoughts but are not as such directly applicable as suitable analytical frameworks in particular they do not provide adequate tools for examining the social preconditions for institutional change needed for environmentally sustainable development

read this paper later procrastination with time consistent preferences a model of time consistent procrastination is developed to assess the extent to which the observed behavior is compatible with rational behavior when a finite work requirement must be completed by a deadline the remaining time for leisure is an exhaustible resource with a positive rate of time preference the optimal allocation of this resource results in more hours spent working and fewer in leisure the closer the deadline key qualitative findings of psychological studies of academic procrastination are consistent with the standard natural resource management principles implied by the model when suitably adapted to task aversiveness uncertainty and multiple deadlines however quantitatively the fully rational model appears to require an extremely high rate of time preference or elasticity of intertemporal substitution to generate serious procrastination furthermore it cannot explain undesired procrastination

the hyperbolic consumption model calibration simulation and empirical evaluation ur preferences for the long run tend to conflict with our short run behavior when planning for the long run we intend to meet our deadlines exercise regularly and eat healthfully but in the short run we have little interest in revising manuscripts jogging on the stairmaster and skipping the chocolate souffleala mode delay of gratification is a nice long term goal but instant gratification is disconcertingly tempting this gap between long run intentions and short run actions is apparent across a wide range of behaviors including saving choices a 1997 survey found that 76 percent of respondents believe they should be saving more for retirement looking only at respondents who believed they were at an age where you should be seriously saving already the survey found that 55 percent reported being behind in their savings and only 6 percent reported being ahead farkas and johnson 1997 the report on the survey concluded t he gaps between people s atti tudes intentions and behavior are troubling and threaten increased insecurity and dissatisfaction for people when they retire americans are simply not doing what logic and their own reasoning suggests they should be doing a 1993 luntz webber merrill lynch survey found similar answers when baby boomers were asked what percentage of your annual household income do you think you should save for retirement and what percentage of your annual

job search and impatience workers who are more impatient search less intensively and set lower reservation wages the effect of impatience on exit rates from unemployment is therefore unclear if agents have exponential time preferences the reservation wage effect dominates for sufficiently patient individuals so increases in impatience lead to higher exit rates the opposite is true for agents with hyperbolic time preferences using two large longitudinal data sets we find that impatience measures are negatively correlated with search effort and the unemployment exit rate and are orthogonal to reservation wages impatience substantially affects outcomes in the direction predicted by the hyperbolic model

information and participation in social programs participation in social programs such as clubs and other social organizations results from a process in which an agent learns about the requirements benefits and likelihood of acceptance related to a program applies to be a participant and finally is accepted or rejected we propose a model of this participation process and provide an application of the model using data from a social program in mexico our empirical analysis illustrates that decision at each stage of the process are responsive to expectations about the decisions and outcomes at the subsequent stages and that knowledge about the program can have a significant impact on participation outcomes

improving takeup of health insurance program a social experiment in france this paper is based on a randomised social experiment conducted in order to understand the low take up rate of a complementary health insurance voucher program for the poorest in france the aide complementaire sante acs we explore two of the main hypotheses put forward to explain low enrolment a lack of information about the program and a voucher amount considered to be too low a sample of eligible individuals living in an urban area in northern france were randomly split into three groups a control group who benefited from the standard level of financial aid a group benefiting from an increase in the value of the voucher and a third group benefiting from the same increase along with an invitation to an information meeting regarding acs we show that the voucher increase has a small but statistically significant effect on acs take up the invitation to the meeting appears to cancel out the positive effect of the voucher increase using an instrumental variable model to control for potential selection bias we find ambiguous evidence of the meeting attendance on acs take up this study confirms the difficulties that are faced in increasing the health insurance coverage of poor populations via subsidy programs

an economic approach to influence activities in organizations members of organizations spend considerable time effort and ingenuity attempting to influence decision makers such influence activities may bring benefits to the organization but they also involve real costs this essay offers an economic rationale for such influence activity as representing rational self interested behavior in the presence of informational asymmetries and an analysis of how the design of the organization s structure and policies should respond to the incentives for attempting influence it is posited that information valuable for the organization s decision making is directly available only to members of the organization who have some personal stake in the decisions these individuals may then have an incentive to try to manipulate the information they develop and provide in order to influence the resulting decisions to their benefits this can be costly both in degrading the quality of decision making and in diverting the attention and effort of the organization s members from more productive activities the organization has three different methods it can employ to discourage excessive influence activities and to encourage more directly productive uses of time and effort it can limit access to decision makers and participation in decision making it can alter its decision making criteria to favor those performing well in productive activities and it can provide direct financial incentives to encourage the desired allocation of effort it is shown that an efficiently designed organization will use such financial incentives only as a last resort instead it will always first alter its decision participation policies and decisionmaking criteria

exploring futures for amazonia s sierra del divisor an environmental valuation triadics approach to analyzing ecological economic decision choices in the context of major shifts in boundary conditions abstract this text presents a new methodological approach to ecological economic analysis employing georgescu roegen s flow fund theory of economic process it offers an alternative to monetary valuation based analyses and aims to contribute toward advancing work concerned with addressing complex ecological economic questions as complete wholes the methodology is demonstrated through reference to the empirical case of a proposed rail link between peru and brazil which would cut across the sierra del divisor of western amazonia connecting the pacific and atlantic coasts and further opening up the amazon commodity frontier in order to analyze the potential impacts of the rail link four flow fund representations of economic process two at the regional and two at the local level are developed in order to juxtapose two alternative political economy contexts that might govern the rail link s impacts in the region one where conservation is prioritized over cash income and one where it is not our results suggest that completion of the rail link under the current political economy context which prioritizes cash income over conservation is likely to have substantial negative consequences for forest conservation in both peru and brazil and for local livelihoods throughout the region

accounting for the value of ecosystem services abstract a value of ecosystem services ves may be calculated by multiplying a set of ecosystem services by a set of corresponding shadow prices this paper examines the role of the ves concept in measuring trends in human well being under conventional arguments from applied welfare economics standard measures of market consumption may be extended to include the value of direct environmental services which affect welfare in ways that are not mediated by the consumption of purchased goods the ves concept does not capture values such as ecological sustainability and distributional fairness that are not reducible to individual welfare and its operationalization is constrained by the well known limitations of nonmarket valuation methods nonetheless attempts to calculate the value of environmental services can provide insights into the tradeoffs between market activity and environmental quality that are implicit in the process of economic growth such efforts can promote informed debate concerning the achievement of sustainable development

economic growth inequality and well being in advanced industrial societies rising levels of inequality have contributed strongly to the observed gap that has emerged between per capita income and the index of sustainable economic welfare isew which in its current versions is known as the genuine progress indicator gpi yet the isew gpi approach to measuring the social costs of inequality has been criticized as ad hoc the present paper reviews the literature on this topic and efforts to resolve it based on the construction of indicators grounded in a a classical utilitarian ethical framework and b empirical evidence on the relationship between income and well being in the united states after tax income per capita grew at an annual rate of 1 7 between 1979 and 2011 a growth rate of 1 2 per year arises when income is adjusted to account for the social costs of inequality the most common adjustment used in isew gpi studies yields a similar growth rate despite much smaller subtractions from baseline income

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

sustainability indicators policy and governance issues for ecological economics abstract ecological economics is a major forum for discussion of theoretical and analytical aspects of measuring sustainability the role of sustainability indicators as an evaluation method for sustainability within the emerging context of governance merits further analysis focusing on policy processes surrounding the production of sustainability indicators this paper addresses two questions what is the potential utility of indicators for policy and in what ways can indicators influence governance the former is addressed by exploring three disciplines with long histories of indicator application public administration studies urban studies and environmental sciences the latter is addressed by distilling key perspectives from public policy literature on knowledge utilisation and policy learning which become the foundation for clarifying the notion of policy resonant indicators this clarification is achieved by canvassing the spectrum of the influences on indicators and the mechanisms of their resonance in policy processes the final section of the paper brings these arguments together by exploring two major insights in terms of challenges for ecological economics strengthening indicator theory and practice by addressing four key ingredients and mobilisation of indicators through their active use within the context of governance

opening the policy window for ecological economics katrina as a focusing event abstract ecological economics and its allied trans disciplinary fields are well established in academia but so far have failed to have significant influence on policy makers public policy research and theory suggest that three process streams must converge in order to shape the political agenda and change policy kingdon j 1984 agenda alternatives and public policies boston little brown first the problem stream emerges when an existing condition is defined as a problem a discrepancy between current reality and a desired goal and critical policy makers accept the definition of the problem the policy stream emerges as consensus grows around policy instruments to solve the problem the politics stream emerges as the national mood and leading politicians accept the gravity of the problem and are willing to implement the policies required to address it when these three streams converge a policy window is created that can move issues onto the political agenda and into formal policy a focusing event like katrina can bring these three process streams together however different strategic representations of the situation may allow entirely different problem definitions and policies to dominate the political agenda this paper analyzes the extent to which katrina has opened a policy window for ecological economics we find that katrina has strengthened the three streams necessary to create a policy window for ecological economics but that the dominant economic paradigm currently on the political agenda market fundamentalism is strategically presenting katrina as supporting its own problem stream and policy stream key elements of the ecological economic agenda such as investing in natural capital are making it on to the political agenda but overall market fundamentalist policies appear likely to dominate we argue that ecological economists have failed to galvanize public acceptance for the policy goals of sustainable scale and just distribution thus failing to effectively communicate their perspectives on problem definition and or policy solutions to policy makers and the voting public we conclude with suggestions for how ecological economists can still take advantage of the katrina window and better prepare for future windows opening

the rhetorics of ecological economics since the early 1980s there has been a lively discussion about the rhetoric of economics ecological economists however so far have not tried to incorporate this discussion into their work this paper is a first step towards including the discourse on rhetoric into the self awareness of ecological economics after a brief outline of what this discourse is about the importance of metaphors as one aspect of rhetoric is examined connections of the rhetorical discourse to ecological economics as a post normal science are shown it is argued that two rhetorics of ecological economics can be distinguished internal and external rhetoric while the former refers mostly to methodological issues the latter is of particular importance for the political impact that ecological economics can have finally some suggestions for research are made

different ways of knowing a communicative turn toward sustainability abstract despite the urgency of the ecological crisis the steady continuation of environmental degradation suggests that new ways of interpreting problems and acting with environmental integrity may need to be considered this paper draws on a broad range of contemporary theory to argue that the conventional conceptualization of environmental problems has remained a largely disciplinary based exercise that has relied on abstracting the environmental issues from their real world complexity a practical articulation of the main environmental narratives reveals self referential discourses whose disciplinary based practices have insulated these approaches from a broad range of contemporary theorising and different ways of knowing the dominance of these approaches in environmental policy development has led to the continued acceleration of environmental degradation despite widespread political and social interest in its abatement this paper provides a critique of methodologies derived from the assumptions of instrumental rationalism and contemplates the potential for alternative communicative approaches and strategies for dealing with environmental policy development and implementation it is argued that a communicative approach to planning for sustainability represents a more appropriate strategy for mobilising a currently impotent environmental movement a communicative approach by explicitly dealing with the assumptions and motivations of contested positions in the sustainability debate it is argued offers the most pragmatic way of developing change strategies to deal with the complex issues surrounding environmental policy development and implementation

masters of our time impatience and self control in high level chess games this paper presents empirical findings on gender differences in time preference and inconsistency based on international high level chess panel data with a large number of observations including a control for ability due to the time constraint in chess it is possible to study performance and choices related to time preferences the results suggest that men play shorter games on average and pay a higher price to end the game sooner they also perform worse in shorter game compared to women but better in longer games furthermore women perform worse in time pressure the 40th move time control the results are consistent with the interpretation that men are more impatient with a lower discount factor but also more inconsistent in the sense that they tend to be too impatient women on the other hand are more inconsistent as they tend to over consume reflection time in the beginning leading to time pressure later

stop go monetary policy we propose and estimate several discrete choice models of monetary policy decision making that feature time varying inertia the models permit us to account for three stylized facts characterizing monetary policymaking in the united states 1 target interest rates are gradually adjusted in small discrete movements 2 there are some long stretches of time in which rates are repeatedly moved and 3 there are other long stretches in which the policy rate does not change our models are used to account for the fed s failure to adopt promptly an easier policy stance during the recession of 2001 they are also used to explain delay in tightening the policy stance during the 2003 2006 period that featured a bubble in house prices and was followed by a financial crisis in 2008

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

bioeconomics and post keynesian economics a search for common ground abstract this paper is concerned with the links between two schools of economic thought which challenge the neoclassical synthesis bioeconomics refers to that school of economics stressing the fact that the human species is a part of the larger biosystem of the planet and ultimately subject to the same laws and limitations as other life forms post keynesian economics is a specific school of macroeconomics stressing the fundamental ideas of keynes marx and kalecki concerning uncertainty the nature of production and the role of government in economic affairs bioeconomics and post keynesian economics have much in common in terms of their methodological framework their emphasis on production rather than exchange and their interpretation of the social rate of discount a potential area of conflict between the two schools is their attitude toward economic growth the areas of commonality between the two schools are discussed and a research and policy program which combines the insights of both approaches is suggested

why are grain legumes rarely present in cropping systems despite their environmental and nutritional benefits analyzing lock in in the french agrifood system grain legume plants fix atmospheric nitrogen in the soil and thus do not need nitrogen fertilizers therefore grain legumes can potentially decrease global warming as nitrogen fertilization is responsible for half of all agricultural greenhouse gas emissions moreover grain legumes have many functional and nutritional properties both as feed and food despite the fact that the european union has granted considerable subsidies to promote grain legume cultivation their production continues to fall and there has been no satisfactory explanation as to why this study provides an answer by showing that a situation of technological lock in has resulted from the co evolution of crop systems based on an agrochemical paradigm public policies and market dynamics that promote cereals this process began with the historical choice by european and french public institutions to relegate grain legumes to feed in direct competition with imported soybeans moreover interrelated factors such as breeding selection public subsidies and food systems have favored increasing returns to adoption for cereals to the detriment of grain legumes finally the evolutionary economics approach used here identified several actions that must be implemented together such as agricultural cost accounting methods nitrogen management institutional innovations and market outlets to promote grain legumes and move towards more sustainable agriculture

how do contribution limits affect contributions to tax preferred savings accounts abstract contributions to tax preferred savings accounts are typically constrained by a contribution limit these limits influence contributions not only for taxpayers currently constrained by the limit but also for those contributing less than the limit i develop a simple life cycle model in which taxpayers exhibit use it or lose it contribution behavior this connects current contributions to future contribution limits and implies that an increase in contribution limits can decrease contributions empirical evidence from microdata provides support for the model using variation from canadian limit reforms i find that larger future contribution room is associated with smaller contributions

concepts of efficiency in ecological economics sisyphus and the decision maker abstract efficiency forms the bedrock of policy planning and business approaches to sustainable development but what do ecological economists mean by efficiency in the resource use context efficiency has a wide range of potential interpretations from the ratio of work output energy inputs to pareto efficiency despite the potential richness of the efficiency concept in practice efficiency is often narrowly conceived within disciplinary boundaries this appears to be the case even in ecological economics which purports to be transdisciplinary and pluralistic such narrow disciplinary perspectives essentially waste the richness of the efficiency concept this wasting could mean ecological economists and decision makers are destined to sisyphean toil in the pursuit of sustainable development this paper explores the efficiency concept and its interpretation it then reviews ecological economic literature to find that there is much room for improvement in the way ecological economists apply efficiency finally the paper presents a framework within which a truly ecological economic approach to efficiency can emerge armed with this framework policy makers and planners should be better prepared to make decisions leading to sustainable development

why ecological economics needs to return to its roots the biophysical foundation of socio economic systems abstract ecological economics was formally established in 1989 with the ambitious vision of developing a new economic paradigm embedding the social and economic systems in the biophysical world ecological economics had its roots in the biophysical understanding of economics that pioneers of the field georgescu roegen 1971 odum 1971 daly 1977 jansson 1984 martinez alier 1987 and others developed while studying the thermodynamic bedrocks shared by natural and social systems subsequently however ecological economics has explicitly but controversially adopted a big umbrella approach to methodological pluralism focusing more on topics such as valuing nature and its functions rather than attempting to understand and quantify the biophysical roots of economic activities biophysical economics was established in response to these concerns focusing more on developing analyses and models of the transformations of nature to generate wealth and approached mostly from an energy and material flows perspective the present paper argues that to achieve its original vision ecological economics must return to its biophysical roots collaboration between the two fields will help the next generation of thinkers to address the socio ecological challenges of the 21st century requiring an energy transformation called for by aspirations such as the green new deal and the un sustainable development goals

organizing a public ecosystem service economy for sustaining biodiversity abstract the core question this paper attempts to address is how social organization needs to respond to biodiversity features and functions in order to achieve its sustainable use scholars have suggested that the governance of complex systems should be dispersed across multiple centers of authority and that any regulative system needs as much variety in the actions that it can take as exists in the system it is regulating further it has been argued that complex ecosystems and biodiversity can successfully be maintained by complex polycentric multi layered governance systems which have a variety of response mechanisms but how should polycentric governance of biodiversity be organized borrowing from the organization of public economies in metropolitan areas we distinguish between production and provision of public ecosystem services and suggest the direction of institutional change for the organization of a public ecosystem service economy if the market alone cannot solve the allocation of public ecosystem services economic efficiency criteria based on hypothetical markets are not sufficient therefore we suggest design principles which go beyond economic efficiency and provide examples of the emergence of polycentric governance from an ethiopian coffee forest conservation project

applying methodological pluralism to wildlife and the economy abstract methodological pluralism is important when we study complex systems we aim to show that methodological pluralism yields additional insight by applying it to a specific question how are the economy and wildlife related in developed and developing countries we identify three possible ingredients of methodological pluralism 1 using both qualitative and quantitative information 2 tapping the potential of history to illuminate slow moving variables and 3 explicitly synthesizing either individually or in groups by thinking about the corresponding system we illustrate with examples

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

the case for methodological pluralism abstract ecology and economics share the same greek root both address complex systems ecology consists of numerous approaches to understanding natural systems energetics population biology food web models hierarchy theory to mention just a few within ecology field knowledge and the reporting of new observations are well respected economics on the other hand is dominated by one pattern of thinking and standard of proof the market model and econometrics within economics field knowledge and observations per se are little valued agreement on a correct method is frequently taken as an indication of the maturity of a science the argument is developed in this paper that all the aspects of complex systems can only be understood through multiple methodologies the agreement on method within economics however seems to reflect stronger pressures within the discipline for conformity than for truth relative to ecology since ecological economics seeks to understand a larger system than either economics or ecology seeks to understand a diversity of methodologies is appropriate and pressures to eliminate methodologies for the sake of conformity should be avoided

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

environmental economics an evolutionary critique and a plea for pluralism abstract environmental economics is a contradiction in terms the contradiction is intuitive to the puzzled lay person inquiring about the nature of our subdiscipline it is explicit to those who think of environmental systems in terms of complex evolving interconnectedness and identify the economic model with the atomistic and mechanistic assumptions of classical mechanics within the subdiscipline we try to resolve the contradiction by internalizing externalities by matching market feedbacks with environmental relations while acknowledging that insights can be drawn from the market view of environmental problems i argue in this essay that 1 the contradiction is nerver resolved 2 multiple incongruous perspectives are all we have for understanding the interface between economic and environmental systems and 3 environmental economics will thrive with a return to philosophical pluralism to the open acceptance of the contradiction

response to robinson and lebron learning from complementary approaches to soil natural capital and ecosystem services abstract we respond to the recent commentary of robinson and lebron in press on our framework to quantify and value soil natural capital and ecosystem services dominati et al 2010 we argue that the framework proposed by robinson et al 2009 and our framework dominati et al 2010 should be seen as complementary as well as having some areas of overlap

procrastination and obedience in this lecture i shall focus on situations involving repeated decisions with time inconsistent behavior although each choice may be close to maximizing and therefore result in only small losses the cumulative effect of a series of repeated errors may be quite large thus in my examples decision makers are quite close to the intelligent well informed individuals usually assumed in economic analysis but cumulatively they make seriously wrong decisions that do not occur in standard textbook economics this lecture discusses and illustrates several pathological modes of individual and group behavior procrastination in decision making undue obedience to authority membership of seemingly normal individuals in deviant cult groups and escalation of commitment to courses of action that are clearly unwise in each case individuals choose a series of current actions without fully appreciating how those actions will affect future perceptions and behavior the standard assumption of rational forwardlooking utility maximizing is violated the nonindependence of errors in decision making in the series of decisions can be explained with the concept from cognitive psychology of undue salience or vividness for example present benefits and costs may have undue salience relative to future costs

new foundations for ecological economics abstract ecological economics has been repeatedly described as transdiciplinary and open to including everything from positivism to relativism i argue for a revision and rejection of this position in favour of realism and reasoned critique looking into the ontological presuppositions and considering an epistemology appropriate for ecological economics to meaningfully exist requires rejecting the form of methodological pluralism which has been advocated since the start of this journal this means being clear about the differences in our worldview or paradigm from others and being aware of the substantive failures of orthodox economics in addressing reality this paper argues for a fundamental review of the basis upon which ecological economics has been founded and in so doing seeks improved clarity as to the competing and complementary epistemologies and methodologies in part this requires establishing serious interdisciplinary research to replace superficial transdisciplinary rhetoric the argument places the future of ecological economics firmly amongst heterodox economic schools of thought and in ideological opposition to those supporting the existing institutional structures perpetuating a false reality of the world s social environmental and economic systems and their operation

ecological economics in china origins dilemmas and prospects abstract this paper is a first step towards articulating a chinese version of ecological economics over the last decade ecological economics has attracted increasing attention in the west similarly since the early 1980s scholars in china have undertaken specific research on existing ecological economic issues in accordance with chinese political economic socio cultural and ecological conditions however this endeavor is hardly known in the west and little attention has been given so far to the potential role of chinese attitudes in the international ecological economics movement this paper is designed to make up for that neglect and attempts to address the following questions what social and cultural traditions are required for chinese ecological economics to operate what are the political and institutional implications of ecological economics in china will chinese ecological economists feel comfortable in a society where open debate is viewed as unacceptable behavior in order to clarify the chinese interpretation of ecological economics and its impact on the policy making process a preliminary overview of its emerging background evolutionary history key viewpoints and theories nature and policy influence is presented three major intellectual sources of chinese ecological economics are identified and the theoretical applications are emphasized then some theoretical and practical issues that may arise in future research are discussed along with implications of chinese ecological economics for the international community in addition to biophysical functions and ecological conditions socio political structures and processes need to be explicitly addressed in extending the research agenda of ecological economics

the value of biodiversity markets society and ecosystems the value of biodiversity is discussed at different levels including market value non market values to humans and the value of biodi versity to ecosystems the main conclusion is that although market exchange values of environmental services may be used to justify biodiversity protec tion measures it must be stressed that exchange value constitutes a small portion of total biodiver sity value the total value of existing biodiversity is largely unknown but indications are that it is essen tial to human existence the various levels of biodi versity value point to the need for a hierarchical and pluralistic methodology to determine appropri ate policies for its preservation jel q21 i introduction among ecologists there is a general con sensus that biodiversity1 is of critical impor tance to the health of ecosystems and even for the long term survival of the human species there is also a consensus that bio diversity is being lost at a rate which is a cause for concern 2 economists on the other hand generally view biodiversity as just an other good which is to be placed in the basket of market choices just as any other the discussion of the specifics of biodiver sity policy has been unsatisfactory partly because of the different meanings of the word value used by economists and ecolo gists many ecologists fail to understand the logic of market allocation and why biologi cal resources are used in seemingly irra tional ways many economists fail to ap preciate the narrowness of the concept of economic value as indicated by relative prices determined by market exchange fol lowing anderson 1966 and brown 1984 the discussion below considers economic measures of value to be species of the genus assigned value which belongs to the family value many biologists and paleontologists be lieve that we are at a critical point in the history of the human species and perhaps even in the 600 million year history of com plex multicelled life on earth if the paleon tologists and biologists who study the phe nomenon of mass extinction are correct the current human induced mass extinction may be of the same order of magnitude as the five other major extinction episodes which destroyed between 20 and 96 percent of existing species on the planet ehrlich and ehrlich 1992 ward 1994 wilson 1992 we are living in a truly remarkable period in earth s 41 billion year history the valua tion decisions our species has made in the recent past and will make during the next few decades will determine the fate of life on earth for the next tens of millions of years it is critical to clarify the language and concepts we use to estimate the value of biodiversity and thus policies leading to its destruction or preservation the importance attached to the issue of biodiversity preservation necessarily in volves ethical judgments about duty to fu ture generations and responsibility toward the nonhuman natural world although in dividuals hold a variety of conflicting beliefs about human responsibility to the natural world this does not mean that policy choices

a dynamic approach to forest regimes in developing economies abstract in the developing economies optimal forest regimes should incorporate the socio economic characteristics of the user groups and since socio economic factors will change with time optimal forest regimes will also follow a dynamic path the two most important socio economic factors are the heterogeneity of the user group with respect to forest management and the direct dependence of the user group on forest normally the heterogeneity will increase and dependence will decrease with economic growth of user group an optimal control model is used to integrate the dynamics of natural system such as joint product of forests and its growth function and the dynamics of the two socio economic factors heterogeneity and dependence the model demonstrates that the dynamics of optimal forest regimes will depend upon the change in natural factors socio economic factors and on the interactions between natural and socio economic factors hence optimal forest management strategies would require a continuous refinement in forest management regimes instead of static state regimes as local communities in developing economies pass through different phases of economic growth

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

technological diffusion and preference learning in the world of homo sustinens the challenges for politics abstract this article relates agents learning of a preference for a technology competition of technologies and their relative diffusion among potential adopters competitive interactions between two technologies are captured by an extended lotka volterra model to also incorporate preference learning on the part of potential adopters of these technologies we combine it with a model of cultural learning based on role model conformist and hedonistic learning our theoretical analysis is illustrated by a concrete example the competition between electric mobility and conventional forms of individual mobility the model enables an evaluation of specific policy instruments as to the promotion of sustainable technology

an ecological monetary theory abstract while money is critical to the modern world ecological economics does not have a theory of money that is applicable to its theoretical framework and policy prescriptions accordingly the field often defers to an orthodox conception of money that is historically inaccurate and ontologically inconsistent the dualized nature of western philosophy informs orthodoxy by defining money according its function as a medium of exchange this conceptualization creates logical and historical problems that can be addressed by exploring an interdisciplinary literature that defines money according to its nature as a social relation expressed in a unit of account this paper develops an ecological monetary theory that is simultaneously rooted in a socio historical understanding of money s nature and in an ontology of social and ecological embeddedness such a theory provides ecological economists and others concerned with social and ecological equity with a framework from which to address monetary systems and policy

entropy structure and organisational change abstract the paper sets out a basis for rigorous thermodynamic characterisation of structural change and of organisational interdependencies between economic and environmental processes many attempts have been made to exploit entropy as a generic explanatory variable it has widely been proposed that entropy is a measure of the level of dis order of a system of how mixed up things are then as organisation is often thought synonymous with some notion of order it has been a small step to propose that increasing organisation is the converse of increasing entropy another suggestion has been that social system structure and change can be explained in terms of a tendency towards maximum entropy production the lotka principle of maximum energy dissipation all these notions must be rejected the putative entropy order connection has its inspiration in boltzmann s probabilistic interpretation of thermodynamic entropy as a measure of microscopic disorder this order principle is simply not applicable under conditions far from thermodynamic equilibrium prigogine conditions which prevail for all important economic and ecological processes under such conditions the relationship between entropy production and changes in structure or organisation is multi faceted and situation specific attempts to account for the specificity of societal activities in terms of a generic scalar measure of organisation or dissipation are largely after the fact and in no way do away with the need for analysis of institutional and ethical dimensions of human action in their own right when properly allied to institutional analysis however the far from equilibrium thermodynamics furnishes a rich impetus for a coevolutionary perspective in ecological economics with promise of incisive treatments of in particular issues of system environment codependency and of the time in determinacies of economy environmental change

new evolutionary foundations theoretical requirements for a science of sustainability abstract ecological economics stands in theoretical and ethical opposition to many aspects of neoclassical economic theory despite their sound critiques of that theory ecological economists have not settled on an alternative theory of human behavior as a potential alternative norgaard s socioecological coevolutionary framework remains underspecified in terms of variation heredity and selection i review concepts and insights on human behavior from evolutionary biology and evolutionary social science in order to supply new theoretical tools for ecological economic problems and help refine the coevolutionary framework i argue that a synthetic evolutionary theory of human behavior provides a sufficient alternative to the neoclassical perspective and that cultural evolutionary theory is a necessary prerequisite of a mature economic science ecological coevolutionary or otherwise finally i suggest some potential topics that such a mature theory might begin to tackle

the role of economics in global management of whales re forming or re founding iwc abstract the global management of whale species identified as an economic mixed good is addressed by means of economic theory of bargaining and institution making i will analyse i why it is important to take into account explicitly both consumptive use and non use values within international conventions on global mixed goods ii the role and nature of institutions dealing with global issues iii the role of bargaining between conflicting interests as a focal feature of the institution making process and iv the role of economic thinking in international conventions co operative and non co operative solutions are discussed and instruments aimed at achieving co operative bargaining analysed the study has both positive and normative implications with insights on social welfare enhancing institutional reforms although the study is broad yet special focus is given to the international whaling commission iwc this paper concludes that we should make economic theory operational within the realm of global institutions on the basis of the bargaining model the conclusion is that iwc should necessarily be re founded or at least re formed changing the convention from whaling to a whale it is suggested that the possibility of introducing compensatory side payments into the bargaining arena in order to increase social welfare and enforceability with respect to a ban scenario be investigated ethical implications of monetary compensations are considered in parallel with economic efficiency the limits and potentialities of economics and economic instruments are also tested globally with respect to the whale and other environmental issues

ecological economics in relation to democracy ideology and politics two recent studies and policy documents are discussed in the present article one is a un report prepared by experienced politicians as input into the 2012 rio de janeiro conference the other a st

evolution of macro information systems for sustainable development abstract the changing perception of the environmental problem as articulated in the brundtland report has shifted the issue of environment information from an almost exclusive focus on pollution towards changes in natural productivity and resource depletion this has reorientated environmental data needs towards the macro perspective of national accounting as reflected in natural resource stocks and flows indicators of the state of environment and sustainable development the stockholm conference 1972 raised the question of the need for a system of environment statistics complementary to and integratible with the body of social and economic statistics we propose here a conceptual framework which tracks stocks and flows of natural resources incorporates a critical set of indicators of ecological integrity at the eco region level and has the capacity to integrate certain parameters in the system of national accounts sna with those found in natural resource accounts nra and state of environment reporting soe reports the emphasis is on the applied side of macro information systems of ecological economics as it has so far evolved from the experience of official government statistics the final section briefly reviews developments in canada and suggests some future directions

values ideology and politics in ecological economics abstract ecological economics is built on a value commitment to study environmental issues and to contribute constructively to a more sustainable development path however many ecological economists still hesitate it appears to depart too much from other scholars by openly addressing issues of values and ideology in this essay the role of the scholar s orientation with respect to values and ideology is addressed it is observed that not only scholars but also actors in society are guided by their ideological orientation this leads to the idea that some of the weaknesses of economic man and profit maximising firm assumptions can be mitigated by introducing a political economic person and a political economic organisation

a bibliometric account of the evolution of ee in the last two decades is ecological economics becoming a post normal science abstract in ecological economics the debate on formalism and formalization has been addressed in the context of a lively discussion on ecological economics as a post normal versus normal science using ecological economics ee as a seed journal and applying bibliometric techniques to all 2533 the articles published in ee from january 1989 to december 2009 we analyze the evolution of the field of ecological economics aiming to shed light on this debate we observe the predominance and increased relevance of certain research topics methodological issues policies governance and institutions and valuation moreover collective action technical change and the environment and values stand as emergent themes of research finally we note that ecological economics experienced an empirical turn reflected in a shift away from exclusively formalized papers towards exclusively empirical and to a larger extent formal and empirical ones the combination of the prominent and emergent topics and the empirical turn mirrors the increasing awareness among researchers in the field of the need to address a key specificity of ecological economics the interdependence of the economic biophysical and social spheres on this basis we argue that at least through the lens of ee ecological economics has evolved towards a post normal science

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

ecological economic modeling in a pluralistic participatory society abstract this paper discusses the evolution of the role of the scientist and clarifies the demands on all scientists who wish to have their scientific results well represented in public debate this evolution is traced starting with the progressive movement in the late 1800s when the neutrality of scientists was taken for granted and the facts were believed to be sufficient to resolve most public policy questions to the current situation marked by the increasingly tentative nature of scientific inquiry disagreement among experts within a specific discipline and interdisciplinary conflict reflected in competing paradigms and interest groups given this perspective on scientific inquiry and modeling the process of convincing one s peers and the public at large is only partially separable in spite of symptoms of information overload rigorous analysis is a prerequisite to having anything persuasive to say to either group easy to understand explanations are dependent on not a short cut around such analysis the paper discusses some specific recommendations on how scientists can contribute to the pluralistic policy formulation process

scientific methodology for ecological economics abstract positivist philosophy has dominated scientific research throughout most of the twentieth century positivism has been discredited within the philosophy of science but this has only had limited impact on research practices in the social and natural sciences economists have called for the adoption of positivism in economics however economic methodologists have noted that this application has not taken place and because of the limitations of positivism it is unlikely that it will take place ecological economists should learn from the methodological failures of economics and look for alternatives since the 1970s several alternative paradigms to positivism have emerged post normal science and constructivism are critically considered and their significance for the discipline of ecological economics is addressed in this paper i propose a modification of the paradigmatic basis of constructivism and suggest that the revised constructivist paradigm should be seriously considered for adoption by ecological economists i also point out that there are complementarities between post normal and constructivist methodologies that deserve further exploration this could enrich the methodological base of ecological economics

ecological macroeconomics an application to climate change ecological economics has not paid sufficient attention to the macroeconomic level both in terms of theory and modeling yet key topics debated in the field of ecological economics such as sustainable consumption reduction in working time the degrowth debate the energy exergy link and the rebound effect require a holistic and macro perspective while this deficiency has been identified before and keynesian economics has been generally suggested as a potent vehicle to establish economic system s thinking very little concrete theorizing and practical suggestions have been put forward we give further credence to this suggestion and demonstrate the value of tackling key concerns of ecological economics within a keynesian growth framework contextualized by an application to climate change we suggest that policy relevant recommendations need to be based on a consistent view of the macroeconomy we end with laying out key building blocks for a keynesian model framework for an ecological macroeconomics authors abstract

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

description prescription and the choice of discount rates abstract the choice of discount rates is a key issue in the analysis of long term societal issues in particular environmental issues such as climate change approaches to choosing discount rates are generally placed into two categories the descriptive approach and the prescriptive approach the descriptive approach is often justified on grounds that it uses a description of how society discounts instead of having analysts impose their own discounting views on society this paper analyzes the common forms of the descriptive and prescriptive approaches and finds that in contrast with customary thinking both forms are equally descriptive and prescriptive the prescriptions concern who has standing i e who is included in society how the views of these individuals are measured and how the measurements are aggregated such prescriptions are necessary to choose from among the many possible descriptions of how society discounts the descriptions are the measurements made given a choice of measurement technique thus the labels descriptive approach and prescriptive approach are deeply misleading as analysts cannot avoid imposing their own views on society

sustainable development in a post brundtland world not yet two decades after the publication of our common future the world s political and environmental landscape has changed significantly nonetheless we argue that the concept and practice of sustainable development sd as guiding institutional principle as concrete policy goal and as focus of political struggle remains salient in confronting the multiple challenges of this new global order yet how sd is conceptualized and practiced hinges crucially on the willingness of scholars and practitioners to embrace a plurality of epistemological and normative perspectives on sustainability the multiple interpretations and practices associated with the evolving concept of development and efforts to open up a continuum of local to global public spaces to debate and enact a politics of sustainability embracing pluralism provides a way out of the ideological and epistemological straightjackets that deter more cohesive and politically effective interpretations of sd using pluralism as a starting point for the analysis and normative construction of sustainable development we pay particular attention to how an amalgam of ideas from recent work in ecological economics political ecology and the development as freedom literature might advance the sd debate beyond its post brundtland quagmire enhanced levels of ecological degradation vast inequalities in economic opportunities both within and across societies and a fractured set of institutional arrangements for global environmental governance all represent seemingly insurmountable obstacles to a move towards sustainability while these obstacles are significant we suggest how they might be overcome through a reinvigorated set of notions and practices associated with sustainable development one that explicitly examines the linkages between sustainability policies and sustainability politics

relative and absolute scarcity of nature assessing the roles of economics and ecology for biodiversity conservation abstract our aim in this essay is to identify and analyze some of the difficulties with interdisciplinary integration of economic and ecological contributions to the study of biodiversity loss we develop our analysis from a widely accepted definition of economics which is based on the concept of scarcity taking a closer look at this notion we find that economics actually limits itself to a very particular aspect of scarcity which we denote as relative scarcity we describe in what respect the economic approach towards biodiversity is based on this notion and also reflect on the specific understanding of the relation of humans and nature behind the economic approach we then turn to absolute scarcity as another notion of scarcity and show that this is not within the scope of economics but has been a theme of ecology and ecological economics we describe in which way ecological and ecological economic approaches towards biodiversity are based on the idea of absolute scarcity and also reflect on the specific understanding of the human nature relationship behind this notion of scarcity against this background we discuss the roles of economics and ecology for nature conservation we conclude that the interdisciplinary integration of ecology and economics requires a philosophical underpinning and suggest a framework for further research

tying odysseus to the mast evidence from a commitment savings product in the philippines we designed a commitment savings product for a philippine bank and implemented it using a randomized control methodology the savings product was intended for individuals who want to commit now to restrict access to their savings and who were sophisticated enough to engage in such a mechanism we conducted a baseline survey on 1777 existing or former clients of a bank one month later we offered the commitment product to a randomly chosen subset of 710 clients 202 28 4 percent accepted the offer and opened the account in the baseline survey we asked hypothetical time discounting questions women who exhibited a lower discount rate for future relative to current trade offs and hence potentially have a preference for commitment were indeed significantly more likely to open the commitment savings account after twelve months average savings balances increased by 81 percentage points for those clients assigned to the treatment group relative to those assigned to the control group we conclude that the savings response represents a lasting change in savings and not merely a short term response to a new product

estimating individual discount rates in denmark a field experiment we estimate individual discount rates with respect to time streams of money using controlled laboratory experiments these discount rates are elicited by means of field experiments involving real monetary rewards the experiments were carried out across denmark using a representative sample of 268 people between 19 and 75 years of age individual discount rates are estimated for various households differentiated by socio demographic characteristics such as income and age our conclusions are that discount rates are constant over the 12 month to 3 year horizons used in these experiments and that discount rates vary substantially with respect to several socio demographic variables hence we conclude that it would be reasonable to assume constant discount rates for specific household types but not the same rates across all households

an ecological economic approach to forest and biodiversity conservation the case of vanuatu abstract the paper presents an ecological economic approach to forest and biodiversity conservation constructivist philosophy of social science is critically reviewed and adopted as the methodological basis of the approach the paradigmatic basis of ecological economics is discussed and a model of human behavior suited to ecological economics is presented this model accounts for altruistic normative affective and irrational behavior as well as the role of institutions a discussion of participatory land use planning which also accounts for intergenerational equity issues completes the presentation of the ecological economic approach its application to the conservation of forests and biodiversity in vanuatu demonstrates the operational applicability of the proposed approach

economic schools of thought on the environment investigating unity and division how do ecological and heterodox economists differ if at all from each other and from neoclassical economists addressing environmental problems in 2009 we probed this question by conducting an international survey across these communities namely at conferences of the european society for ecological economics the association for heterodox economics and the european association of environmental and resource economists the research was designed to gain insight into the extent to which ecological economics can be described as heterodox and a distinct field from orthodox environmental and resource economics conflicting visions of ecological economics have led to a prevalence of neoclassical articles and thought mixed in amongst more heterodox work we introduce a novel classification of work in the field of environmental policy in order to test for the existence of differences in terms of methodological and ideological approaches how heterodox economists understand environmental issues is also an important question to answer if there is to be more collaboration between them and ecological economists the findings have implications for cooperation and the future direction of both ecological and heterodox economics

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

three dilemmas of environmental accounting abstract economist during the past two decades have tried to logically extended the system of national accounts to include the value of resources environmental systems and their services alternative proposals for improving the accounts have been extensively debated but no agreement has been reached the debate has been fueld by a false implicit belief among the participants that there is one best way to understand how economies interrelate with environmental systems the falsity is exposed through the elaboration of irresolvable dilemmas rather than trying to agree on a single approach the alternative strategy of experimenting with many approaches is espoused the development and use of multiple approaches would be scientifically more rigorous and more likely fail safe

are there environmental limits to cost benefit analysis this paper considers the problem areas found in applying cost benefit analysis cba to projects involving environmental costs or benefits this is particularly relevant given recent moves by the uk government to include environmental valuations in cba exercises and in other related appraisal activities following the publication of the pearce report the paper argues that a major problem lies in placing monetary values on non market goods the paper also addresses the problems of i differences between citizen and consumer values ii complexity of ecosystems iii irreversibility and uniqueness and iv intergenerational equity and discounting the extent to which cba is an institution open to capture is also discussed

the second generation of ecological economics how far has the apple fallen from the tree this paper examines the discourse produced in the academic journal ecological economics from its inception in 1989 and compares this discourse with that of the field of environmental economics i used methods for discourse analysis alceste and iramuteq on 6308 abstracts of papers published in four journals namely ecological economics the journal of environmental economics and management environmental values and environmental and resource economics published between 1989 and 2013 the results suggest that the discourses of ecological economics and environmental economics have grown closer over time the semantic classification of co occurrent terms used in ecological economics indicates increasing significance of the notions of ecosystem services and of monetary valuation i argue that this trend is parallel to costanza s career path which suggests the rise of a tacit recognition of the new environmental pragmatic scientific approach i conclude with some of the implications for ee of promoting this kind of discourse to such an extent

ecological economic modeling and valuation of ecosystems abstract we are attempting to integrate ecological and economic modeling and analysis in order to improve our understanding of regional systems assess potential future impacts of various land use development and agricultural policy options and to better assess the value of ecological systems starting with an existing spatially articulated ecosystem model of the patuxent river drainage basin in maryland we are adding modules to endogenize the agricultural components of the system especially the impacts of agricultural practices and crop choice and the process of land use decision making the integrated model will allow us to evaluate the indirect effects over long time horizons of current policy options these effects are almost always ignored in partial analyses although they may be very significant and may reverse many long held assumptions and policy predictions this paper is a progress report on this modeling effort indicating our motivations ideas and plans for completion

aging and health financing in the u s a general equilibrium analysis abstract we quantify the effects of population aging on the u s healthcare system our analysis is based on a stochastic general equilibrium overlapping generations model of endogenous health accumulation calibrated to match pre 2010 u s data we find that population aging not only leads to large increases in medical spending but also a large shift in the relative size of private vs public insurance without the affordable care act aca aging by itself leads to a 40 increase in health expenditures by 2060 and a 9 6 increase in gdp which is mainly driven by the increase of the fraction of older higher risk individuals in the economy as well as behavioral responses to aging and the subsequent expansion of the healthcare sector aging increases the premium in group based health insurance ghi markets and enrollment in ghi decreases while the individual based health insurance ihi market medicaid and medicare expand significantly the size of medicare will almost double by 2060 as the elderly dependency ratio increases additional funds equivalent to roughly 2 7 of gdp are required to finance medicare and medicaid the introduction of the aca increases the fraction of insured workers to almost 100 by 2060 compared to 82 without the aca this increase is driven by the stabilization of ghi markets and the further expansions of medicaid and the ihi market the aca mitigates the increase of healthcare costs by reducing the number of the uninsured who pay the highest market price for healthcare services overall the aca adds to the fiscal cost of population aging mainly via the medicaid expansion our findings demonstrate the importance of accounting for behavioral responses structural changes in the healthcare sector and general equilibrium adjustments when assessing the economy wide effects of aging

limits to substitution and irreversibility in production and consumption a neoclassical interpretation of ecological economics abstract there are many methodological approaches within ecological economics one of the principal modes of analysis is a modified version of the standard neoclassical model this paper examines the parallels which emerge between the ideas of some ecological economists concerning production and the ideas of others concerning consumption when these ideas are interpreted in the neoclassical paradigm it is well known that ecological economics is characterized by arguments concerning limits to substitution between inputs energy natural capital etc vs manufactured capital labor etc in production and the implications these have for sustainability however various authors have also expressed concerns regarding limits to substitution in consumption either between environmental assets and other goods or between basic needs commodities and other goods though the specific reasons for non substitution are different in the production and consumption cases the underlying theme is that individual commodities and other inputs have unique physical or other properties which make them poor substitutes ideas about irreversibility in production and economic development are also prominent in ecological economics likewise many authors have argued for similar irreversibilities in consumption behavior in analogy to the term technological change i coin the term preferential change to describe these phenomena the linking themes in this case are that the economy environment system is evolutionary in character and that external effects intended and unintended consequences of actions or processes imposed on other parties or resources are all pervasive

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