are emotions to blame the impact of non analytical information processing on decision making and implications for fostering sustainability policy advice based on a rationalist perspective to foster sustainable behaviour has approached its limits and gaps in the established models are becoming more and more obvious to better understand how unsustainable choices are made and to foster sustainable decision making alternatives to the rationalist models of human decision making need to be investigated such alternative models have already demonstrated their usefulness in other fields than ecological economics the paper begins with a presentation of conventional models of human behaviour as well as their advances and limitations in ecological and behavioural economics in most of these models the dominance of analytical thinking still prevails i identify this as problematic given the evidence for the influence of emotion and intuition in decision making to offer a perspective on human behaviour that acknowledges this influence dual process models are presented established applications of these models are then used to propose four basic types of explanations for unsustainable behaviour based on these explanations preliminary ideas to promote sustainable decision making are developed these ideas are considerably different from policy implications of the established economic model

limits of exact equilibria for capacity constrained sellers with costly search abstract this paper studies finite versions of competitive matching models in which sellers announce prices and buyers understand the relationship between price and probability of trade two equilibrium concepts are studied for finite games subgame perfect equilibrium and rational expectations equilibrium it is shown that the distribution of prices offered by sellers under both equilibrium concepts converges weakly to the same competitive equilibrium distribution of prices furthermore the payoffs that sellers face in both kinds of equilibrium have the market utility property in the limit journal of economic literature classification numbers c78 d41 d45

the new institutional economics this outstanding book presents new original contributions from some of the world s leading economists including ronald coase douglass c north masahiko aoki oliver e williamson and harold demsetz it demonstrates the extent and depth of the new institutional economics research programme which is having a worldwide impact on the economics profession

accounting technologies and sustainability assessment models abstract within ecological economics there is recognition of the need for new approaches to decision making to support sustainable development initiatives there is an increasing acknowledgement of the limitations of cost benefit analysis approaches as a measure of the un sustainability of organizational activities these are viewed as particularly inappropriate within the participatory settings that sustainable development proponents seek to foster they also fail to deal with the highly contested nature of sustainable development discourse in contemporary pluralist democracies while advances have been made in the field of multi criteria decision making there is still a relative dearth of versatile models that accommodate monetization in a way that recognizes the limits of calculative technologies this article introduces readers to developments within the accounting discipline designed to support sustainable development decision making and evaluation in particular it proposes sustainability assessment models as a viable alternative to cost benefit analysis sustainability assessment models are based on an inter disciplinary approach that recognizes the need for accountings that facilitate more participatory forms of decision making and accountability as such they address many of the weaknesses in current approaches to cost benefit analysis the authors first experiences with sustainability assessment models were with bp and the united kingdom oil and gas sector where models were developed as a means of making previously external costs more central to organizational decision making later work has included exploration of a range of decision making situations in private and public sector organizations in both the united kingdom and new zealand this has involved more explicit attention to plural values and issues of participation dialogue and democracy

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

corporate environmental and resource management in search of a new managerial paradigm abstract sustainable development is close to becoming the catchword of the 1990s but it is still far from being an operational concept for individual companies this paper attempts to transform the brundtlandian contradictory of sustainable development into a corporate and more operational concept as it is argued economists interest in the environment is not new whether to implement sustainable corporate environmental and resource management practices or not is no longer a real choice for industrialists today given the ultimate limitations of nature limitations that are close to being reached the implications of such a new corporate development philosophy will be far reaching however the new managerial paradigm which is outlined here challenges not only the way in which industry is run today but attacks the very bedrock on which mainstream economics is based

competitive search equilibrium in this paper i construct an equilibrium for markets with frictions which is competitive in the sense that all agents are price takers and maximize utility subject to a set of market parameters i show that the equilibrium allocation is socially optimal i also show how the competitive search equilibrium can be achieved if employers with vacancies can advertise publicly the wages they pay

a rudimentary random matching model with divisible money and prices abstract we consider a version of kiyotaki and wright s monetary search model in which agents can hold arbitrary amounts of divisible money a continuum of stationary equilibria indexed by the aggregate real money stock exists with all trading occurring at a single price there is always a maximum level of the real money stock consistent with existence of such an equilibrium in the limit as trading becomes faster relative to discounting any real money stock becomes feasible in such an equilibrium in contrast to the original kiyotaki wright model higher equilibrium real money stocks unambiguously correspond to higher welfare in this costless production environment journal of economic literature classification numbers d51 e40

search theoretic models of the labor market a survey we survey the literature on search theoretic models of the labor market we show how this approach addresses many issues including the following why do workers sometimes choose to remain unemployed what determines the lengths of employment and unemployment spells how can there simultaneously exist unemployed workers and unfilled vacancies what determines aggregate unemployment and vacancies how can homogeneous workers earn different wages what are the tradeoffs firms face from different wages how do wages and turnover interact what determines efficient turnover we discuss various modeling choices concerning wage determination and the meeting process including recent models of directed search

economics of sustainability or the sustainability of economics different paradigms this article reviews different views of neo classical and ecological economics on the sustainability of economic growth and welfare neo classical economics concludes that due to substitution and technical progress consumption can be sustained even if production depends on a natural resource that is being depleted if production depends on an essential renewable resource there is a level of consumption that can be sustained forever pollution lowers the level of consumption that can be sustained if production depends on an exhaustible resource recycling of waste is insufficient for sustaining consumption unless 100 recycling is possible sustainable economic development is possible if the resource growth potential exceeds the sum of the discount rate minus the rate of exogenous technical progress and if resource productivity is sufficiently high in addition intial levels of environmental quality a composite of pollution and natural resources and man made capital influence the possibilities for sustainable economic development if the resource stock itself affects utility or if irreversibilities occur optimal consumption and extraction are lowered ecological economics states that substitution possibilities are restricted full recycling of waste is impossible and the limited influx of solar energy poses an additional constraint on the level of production that can be sustained since the functions of the environment production factor consumer good and waste sink are intertwined this life support function poses a restriction on economic growth as well in ecological economics development is viewed as an evolutionary process with continuous feedbacks between a changing economy and environment welfare is not merely the sum of discounted individual preferences but requires environmental compatibility and the explicit collective formulation of policies regarding the conservation of species ecosystems and natural resources

the influence of political orientation on the strength and temporal persistence of policy framing effects abstract the objective of this research is to analyze how political orientation moderates the influence of framing effects on policy evaluation drawing on the theory of motivated reasoning three interrelated experiments assess the strength and temporal persistence of framing effects in the context of an energy conservation program in the first experiment n 183 the delivery mechanism of the policy is described as either a tax rebate or a subsidy party identification of potential beneficiaries moderates the existence and magnitude of framing effects the second experiment n 603 presents alternative frames of communication which focus on either the economic or environmental benefits associated with the policy effects of the communication frames on policy support in comparison to a neutral text are significant but only when the policy is consistent with respondents pre existing views on economic individualism and government spending the third experiment n 603 investigates the temporal stability of framing effects after cognitive deliberation and finds that no change in policy support occurs over time a key implication is that tailoring frames to the target audience increases effectiveness in policy design and communication considering the persistence of framing effects early frames may have a disproportionate impact in public discourse

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

inflation tax in the lab a theoretical and experimental study of competitive search equilibrium with inflation in this paper we measure the effect of the inflation tax on economic activity and welfare within a controlled setting to do so we develop a model of price posting and monetary exchange with inflation and finite populations the model which provides a game theoretic foundation to rocheteau and wright 2005 s competitive search monetary equilibrium is used to derive theoretical propositions regarding the effects of inflation in this environment which we test with a laboratory experiment that closely implements the theoretical framework we find that the inflation tax is harmful with cash holdings production and welfare all falling as inflation rises and that its effect is relatively larger at low inflation rates than at higher rates for instance for inflation rates between 0 and 5 welfare in the two markets we consider 2 seller 2 buyer and 3 2 falls by roughly 1 percent for each percentage point rise in inflation compared with 0 4 percent over the range from 5 to 30 our findings lead us to conclude that the impact of the inflation tax should not be underestimated even under low inflation

niche diversification in environmental ecological economics abstract this paper is devoted to the identification and comparison of the niches of neoclassical environmental economics nee and ecological economics eco it is presented in four sections section 1 argues that the existing literature does not make the differences and relations between the sister disciplines neatly transparent section 2 critically examines the antecedents of the subjects with reference to three structural dimensions such as scarcity perception problem solving orientation and range of integration section 3 collates the elements and reformulates the definitions section 4 is coda on the essay the divide between the paradigms which came to the surface during the 1960s became prominent through the growth controversy of the subsequent decade the controversy over the need for change of economic theory to cope with the growing intensity of environmental uncertainty makes the disciplines sore about each other the neoclassical paradigm comprising of elements like relative scarcity allocative approach market correction and technological optimism characterises nee the distinguishing characteristics of eco include thermodynamic irreversibility absolute scarcity economy ecosystem symbiosis biophysical approach ecological stewardship and prudent pessimism the niches are competitive and complementary in some respects and thus provide a unique example of fruitful niche diversification within environmental ecological economics we have a feeling that the economics profession can trace out the interface of the disciplines in some policy areas and raise the effectiveness of prescriptions so that this academic species diversity can serve humankind to its full potential

marx s reproduction schemes and the environment abstract ecological economists have argued that marx s reproduction schemes are self contained circular flows that downgrade the importance of natural conditions the present paper evaluates this criticism in light of both marx s methodology and his response to quesnay s tableau economique it is shown that marx follows quesnay in clearly distinguishing monetary circular flows from material throughput and that his schemes encapsulate the dependence of capitalist production on natural conditions as developed elsewhere in capital at the same time the purpose of marx s schemes is not to theorize environmental crises but to set out the basic exchanges necessary for capitalist reproduction as a material and social class process marx s analyses of capitalist environmental crises are developed at other points in capital

well being and or quality of life in eu countries through a multidimensional index of sustainability abstract the aim of my paper is to demonstrate that sen s theory of well being can be applied to make the concept of sustainable human development operational through the building of a multidimensional index of sustainability which takes into account at the same time economic social and environmental variables this index may be considered an alternative to the current measures of welfare sustainability since not only conventional measures such as gdp but also multi attribute indices such as human development index hdi genuine savings index of sustainable economic welfare isew etc are found to be inadequate to make the concept of sustainable development operational therefore the limitations of these measures of welfare sustainability justify the search for a new index of sustainability this index will show at the operational level how sen s theory of well being can be useful to sustainable development it was applied to eu countries using the standardised deviation methodology being the closest and most suitable methodology to be adopted for building multidimensional indices the factor analysis methodology will also be used in my paper lastly the comparison between sen s trend of sustainability and gdp trend index number which are both of them applied to italy will show how much the criticisms and the limitations directed towards the indicator of gdp are founded

the goals and promise of the sarbanes oxley act the primary goal of the sarbanes oxley act was to fix auditing of u s public companies consistent with its full official name the public company accounting reform and investor protection act of 2002 by consensus auditing had been working poorly and increasingly so the most important and most promising part of sarbanes oxley was the creation of a unique quasi public institution to oversee and regulate auditing the public company accounting oversight board pcaob in controversial section 404 the law also created new disclosure based incentives for firms to spend money on internal controls above increases that would have occurred after the corporate scandals of the early 2000s in exchange for these higher costs which have already fallen substantially sarbanes oxley promises a variety of long term benefits investors will face a lower risk of losses from fraud and theft and benefit from more reliable financial reporting greater transparency and accountability public companies will pay a lower cost of capital and the economy will benefit because of a better allocation of resources and faster growth sarbanes oxley remains a work in progress section 404 in particular was implemented too aggressively but reformers should push for continued improvements in its implementation by pcaob rather than for repeal of the legislation itself

a model of money with multilateral matching we develop a model of decentralized monetary exchange to examine the distributional effects of inflation across heterogeneous agents the agents have private information about their productivity preferences or money holdings matching is multilateral and each seller is visited by a stochastic number of buyers the good is allocated according to a second price auction in money in equilibrium homogeneous buyers hold different amounts of money leading to price dispersion we find the closed form solution for the distribution of money holdings entry of sellers is suboptimal except at the friedman rule inflation acts as a regressive tax

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

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

the concept of joint production and ecological economics joint production is suggested as one of the conceptual foundations of ecological economics the notion of joint production springs immediately from the application of thermodynamics and has a long history in economic analysis considerations of joint production give rise to philosophical concerns relating to responsibility and knowledge the concept of joint production is easily comprehensible and is also constitutive and supportive of a range of concepts current in ecological economic thought 2001 elsevier science b v all rights reserved

whither monetary economics i argue that monetary economics should be pursued by applying implementation theory to models which contain explicit frictions that make money essential the argument has two parts first i argue that models in which real balances are assumed to be productive models with money in utility or production functions or with cash in advance constraints contain hidden inconsistencies second i argue that the approach advocated is capable of providing new insights about some of the main issues in monetary economics the effects of monetary shocks the welfare cost of inflation and the roles of inside and outside money

money in search equilibrium in competitive equilibrium and in competitive search equilibrium we compare three market structures for monetary economies bargaining search equilibrium price taking competitive equilibrium and price posting competitive search equilibrium we also extend work on the microfoundations of money by allowing a general matching technology and entry we study how equilibrium and the effects of policy depend on market structure under bargaining trade and entry are both inefficient and inflation implies first order welfare losses under price taking the friedman rule solves the first inefficiency but not the second and inflation may actually improve welfare under posting the friedman rule yields the first best and inflation implies second order welfare losses

on the multiplicity of monetary equilibria green zhou meets lagos wright abstract green and zhou relax the assumption made in early search based models of monetary exchange of indivisible money their paper and various extensions make much technical progress and derive some interesting substantive results in particular they show there is an indeterminacy of steady state monetary equilibria we reconsider this result in the framework of lagos and wright which is more tractable we show that a similar multiplicity arises and is much easier to derive and understand we also compare the results to those in related nonmonetary models and discuss how they depend on details including the number of agents and the timing

clarifying the epistemology of corporate sustainability abstract business research is placing increasing focus on the relationship between the natural environment and the political concept of sustainable development within this nexus one area labelled corporate sustainability emphasizes the interactions between economic environmental and social values the need to consider multiple values has contributed to a blur in the conceptual landscape this is partly due to the fact that authors often address epistemological challenges on an implicit level moreover hidden ideologies e g the profit maximization paradigm can explain the conceptual obscurity the contribution of this article is twofold firstly a conceptual framework is developed based on the dichotomy of positivism and constructivism a relation is established between these epistemological positions and the analytic treatment of environmental and social values the framework can be applied to increase transparency on epistemological challenges and thereby strengthening construct validity in the field secondly an analysis of the most influential literature from the last 50 years shows that there is a trend of clustering theoretical positions and value constructs without any critical awareness of their philosophical assumptions the authors hope that acknowledgement of a multi paradigmatic approach can help to clarify the epistemology of the research area by establishing pluralism as an explicit position

equilibrium wage dispersion and interindustry wage differentials this paper develops a search theoretic explanation of interindustry wage differentials given coordination problems in the labor market the probability of filling a vacancy is an increasing function of the wage offered in equilibrium firms that find vacancies more costly will offer higher wages the model thus explains the persistence of interindustry wage differentials and their correlation with industry average capital labor ratio and profitability additionally the model predicts that high wage firms will receive more applications per job opening and that wages in the labor market will behave as strategic complements

developing post normal technologies for sustainability abstract the last two decades have seen the development of an array of techniques and practices aimed at promoting sustainability for many results have been disappointing there are charges that supposedly new organisational approaches remain embedded in managerialist functionalist and anti dialogic frameworks that are a significant part of the problem similarly the technocratic scientization of public policy is viewed as ill equipped to deal with the social economic and ecological issues currently facing neo liberal societies in this paper we seek to interpret these frustrations and identify pathways that move beyond this specifically we argue that the gap between sustainability rhetoric and sustainability practices can be reconceptualised through the practice of science as post normal and through developing the notion of post normal sustainability technologies pnsts the exponents of post normal science show why stakeholder engagement in sustainability and other scientific issues is critical for the legitimacy and quality of decisions and the admission of complexity in decision making and accountability processes building on this now well established foundation we seek to characterise and give examples of pnsts as tools for achieving this participation wherein stakeholders assume expertise and interact with those possessing more traditional forms of expertise in order to co produce knowledge about sustainability recognition of ideological and value diversity is also central to the post normal sustainability agenda and with pnsts the values based nature of the issues involved is articulated in a way that seeks to bring politics openly into the picture to this end we identify processes that are emerging in the literature and in practice that will enable pnsts these include extended peer communities and multi actor heuristics agonistic processes and new characterisations of citizenship that support moves to sustainability in so doing we believe that pnsts offer clumsy solutions for wicked problems that can be engaged with in both the research and practice arenas as significant contributions to addressing urgent needs

humans environment and economies from vicious relationships to virtuous responsibility abstract the debates questioning the meaning of growth point to a need for a more holistic understanding of human beings and of the economic actor fundamental to economic theory and practice this contribution turns to virtue ethics in order to reframe the self in more reflexive relational and environmental terms we explore the significance of understanding humans sense of responsibility that is quintessentially relational and of their capacity and need to relate to nature as well as community and society we begin by reviewing the main arguments in the thriving debate in ecological economics around what the characteristics of the human being can contribute to implement an ecologically sustainable development our aim is then to draw a link between this debate and that of virtue ethics that leads to a different understanding of the human being of what can contribute to individual wellbeing and a good life responsibility we argue is not only a value but a virtue that enables individuals to find meaning in acting responsibly towards the environment emphasising the multiple benefits that arise from framing good lives in active terms we conclude reflecting on the challenges to and implications of our proposition for government institutions particularly education

bertrand equilibrium with capacity constraints and restricted mobility this paper considers price competition among firms when there are capacity constraints and buyers have limited ability to visit firms a natural method of allocating buyers among firms arises in the equilibrium of the buyers search game sufficient conditions are given under which the buyers equilibrium varies continuously with the prices charged by firms capacity constraints are used to guarantee that this ensures existence of mixed strategy equilibria for the pricing game played by sellers we show that natural pure strategy equilibria arise when the game is made large in appropriate ways since bertrand s criticism of cournot it has been known that models where sellers compete with prices may have undesirable properties when the commodities traded are homogenous in the simplest models with constant marginal costs price may be driven down to the competitive level even when there are only two firms more problematic if sellers are subject to capacity constraints nash in prices equilibrium may not exist at all these problems all arise because of a discontinuity in firms profit functions that arises when the prices of two or more firms are equal there have been many attempts to resolve this problem the simplest is to constrain sellers prices to be equal and to force them to compete in quantities this is the basis of most of the literature on monopolistic competi

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

equilibrium price dispersion in a matching model with divisible money the main purpose of this paper is to show that for any given parameter values an equilibrium with dispersed prices two price equilibrium exists in a simple matching model with divisible money presented by green and zhou 1998 we also show that our two price equilibrium is unique in certain environments moreover the welfare effect of price dispersion is analysed

towards a centerpiece for ecological economics this paper offers a hypothesis with cognitive claims for a social theory that is relevant for ecological economics as background a fable has ego metaphorically viewed as a horse driven to problematic extremes with the solution becoming an integration and balance of means with the other horse empathy the ego n empathy hypothesis starting with a new root metaphor which is extended with a pre analytic vision the main support for the cognitive claims is with a mathematical model and a metaeconomic analysis armed with both scope and precision along with an assortment of corroborative evidence from different disciplines the paper provides support for establishing a new center cognitive claims have ego and empathy apart giving value and possibilities and together as ego empathy giving an emergent value possibility this possibility suggests a rallying point for transdisciplinary work and a theoretical centerpiece for ecological economics suited as such the economic ego of homo economicus is distinguished from the political ego of sacro egoismo corroboration with adam smith s moral philosophy political economy is highlighted the individual person of an empirical ethics stemming from both self interest and fellow feeling is resurrected to support the hypothesis awareness emerges like a complementary consciousness an added value strikingly similar to smith s impartial spectator empirical demonstration concludes this integration of interests with a metaeconomic analysis for the case of soil and water conservation policy in the north american farming population taken together the root metaphor with reasonable scope and precision corroboration and demonstration help to structure the ego n empathy hypothesis d 2004 elsevier b v all rights reserved

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

malthus vs wordsworth perspectives on humankind nature and economy a contribution to the history and the foundations of ecological economics abstract in this paper the view of humankind and nature upon which the thinking of malthus is founded will be reflected on and contrasted with the opposed understanding of his contemporary wordsworth we show that the economic considerations of both are based decidedly on the premise of these views and that their alternative interpretations of the contemporary economy and the relationship between economy and nature may thus be explained from the comparison of malthus and wordsworth we draw conclusions for modern ecological economics identifying its malthusian understanding of nature and reflecting on the capacities and limits implied for further research we ascribe a central role in the conceptual history of ecological economics to wordsworth and present his philosophical presumptions as a fruitful alternative for ecological economics finally attention will be drawn to the principle importance of the philosophical foundations underpinning this field of research

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

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

towards an ecological economics of sustainability abstract persistent disagreement both as to the interpretation to be given to sustainability and as to the relation between ecological and economic sustainability has hindered the development of an ecological economics of sustainable resource use this paper identifies the main concepts of sustainability deriving from the two disciplines in order to explore the difference implied by an ecological approach to the problem it is argued that present economic and ecological approaches are largely disjoint and that they address basically different phenomena by combining the efficiency requirements of what is usually thought of as economic sustainability with the stability requirements of an ecological approach it is shown that an intertemporally efficient allocation of resources that satisfies the conditions for constant levels of consumption is not necessary to assure ecological sustainability ecological sustainability requires that the allocation of economic resources should not result in the instability of the economy environment system as a whole

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

some issues in agrarian and ecological economics in memory of georgescu roegen abstract ecological critics of economics have argued for over one hundred years that economists should study the flow of energy and materials in the economy the services nature offers to the human economy cannot be adequately valued in the accounting system of neoclassical environmental and resource economics today s ecological economics does not only critizice it also tries to provide physical indicators in order to judge whether the economy is ecologically sustainable beyond its decisive role in strengthening such ecological economics georgescu roegen s work currently still holds sway in two additional fields consumption theory as analysed by gowdy 1993 and agrarian economics are there relations between such fields of study and ecological economics in this article i shall first focus on the agrarian question and then on intra and inter generational ecological distribution

production and environmental resources a prelude to an evolutionary framework the paper advances a framework to study the evolution of technology and institutions it is based on two simple tenets first the quality and quantity of environmental resources are defined and constrained by the regime of technology and institutions second the character and extent of innovations are informed and limited by the regime as well the framework is contrasted with neoclassical and ecological economics while the framework assimilates ideas from both paradigms it departs from them by stressing the importance of the technological institutional regime tir the two views ignore in different ways the significance of tir 46 the neoclassical program conceives the flow of innovations as tir independent while the ecological agenda regards the fund of resources as tir independent 1 consequently both camps fail to provide an endogenous account of the observed punctuated character of the evolution of tir neoclassical economists maintain that as a resource depletes its price rises which induces switching to a cheaper one encourages exploration or spurs invention harold barnett and chandler morse 7 11 state that nature imposes particular scarcities not an inescapable general scarcity the responses to environmental resource limitation are supposedly singular activities stripped from any underpinning regime the neoclassical disregard of tir heuristically resembles the fable of marie antoinette s folly in response to the scarcity of bread at the eve of the french revolution she advised according to legend buying cake instead ecological economists offer a different view of resource limits 48 for herman daly 21 8 nature really does impose an inescapable general scarcity while neoclassical economists emphasize relative limitation scarcity pricing ecological economists stress malthusian general limitation for ecological economists substitution can solve relative allocation but cannot solve general limitation general limitation can be avoided only if economic activity proceeded within certain boundaries or as put by martin o connor 69 within appropriate cyclical structure of resource transformations under the motto sustainable development a low pace production activity supposedly enables a population to replicate indefinitely ecological economists conceive

intertemporal valuation in an unpredictable environment abstract the inherent unpredictability of ecological systems is a vital feature for the development of theories at the interface between economics and ecology such unpredictability is caused by instabilities that are intrinsic parts of ecosystem function succession and evolution the complexity of ecological dynamics undermines the simple probabilistic treatment of uncertainty based on the equilibrium paradigm common in traditional environmental economics we investigate an important alternative by representing the dynamics of the biogeophysical system as an infinite sequence of instabilities this leads to a stochastic process exhibiting an exponentially growing variance our analysis is carried out in a macroeconomic setting in a situation where the value system here formalized in terms of risk averse social welfare functions contains at least two distinct aspects consumption rate and the state of the environment the central variables for intertemporal valuation i e the time dependent expected values of the two welfare function components are calculated using the probability distribution describing the environmental dynamics one result is that if the unpredictability of the environmental dynamics is taken into account then the social discount rate for environmental existence values may well be negative

cost benefit analysis values wellbeing and ethics an indigenous worldview analysis abstract in cost benefit analysis cba values are often invoked to discuss maximization strategies that produce the highest state of social wellbeing expressed in terms of utility also the conception of preferences is what individuals reveal as contributing to their wellbeing however as cba ignores the empirically testable facts of how preferences are constituted practical question arises about the legitimacy of the values themselves in contributing to welfare maximization this paper seeks to uncover the meaning of wellbeing from lessons drawn from an extensive field study conducted with a group of indigenous people in malaysia between 2008 and 2011 it concludes that despite decades of conceptual and analytical refinement the price based cba is still limited in the practical world of evaluation because of the real difficulties it encountered in assessing the non use and indirect use components of environmental assets that are non subjectively distinguishable or are not traded in the market also in ignoring individuals value judgment and the various meanings of wellbeing from different socio cultural backgrounds cba tends to lead to welfare distortions to address these theoretical and practical deficiencies it is necessary to embrace the heterodox school of ecological economics focusing on the social cultural and biophysical aspects of valuation processes

feminism ecology and the philosophy of economics abstract the contemporary discipline of economics pays little heed to either the natural environment or to the work of women a review of the literature on the historical development of western concepts of self and science shows that this is not coincidental rather than suggesting that ecological economics reinforce the identification of women with nature however feminist thought suggests that dualistic thinking about men and women humans and nature can be should be replaced with a fuller picture of human identity and knowledge

neoclassical and institutional approaches to development and the environment abstract institutional economics is suggested as a more fruitful approach to environmental problems than the now dominant neoclassical paradigm the historical background of institutionalism in the united states and europe is given as well as the main characteristics of this approach i e holism emphasis on institutional arrangements pattern modelling and emphasis on the political element of economics differences between neoclassical and institutional economics are elaborated with respect to the concept of economics reductionist versus holistic the approach to decision making aggregated versus highly disaggregated and the view of social and institutional change public choice versus actor network approach

ecological economics and sustainable governance of the oceans abstract this paper is an introduction and synthesis of the papers that appear in this special issue devoted to the sustainable governance of the oceans the special issue contains papers on various aspects of the problem including the ecological and economic importance of the oceans the problems facing the oceans from an ecological economics perspective the links between science and policy the rationale for sustainable ocean governance and examples of sustainable institutions and governance structures we developed the lisbon principles of sustainable governance responsibility scale matching precaution adaptive management full cost allocation and participation as a core set of guidelines for sustainable ocean governance we then describe the major problems facing the oceans in terms of how the principles are violated and evaluate some suggested institutions in terms of how the principles are incorporated

aggregation and deliberation in valuing environmental public goods starting from a distinction between kantian principle based and utilitarian preference based approaches in political theory this essay argues that we may understand normative judgments individuals make about policy to express principled views of the public interest or purpose not private preferences about their own consumption opportunities these judgments in other words state opinions about what we ought to do as a society rather than report preferences about what i want as a utility maximizer this essay then argues that contingent valuation can take into account these kinds of judgments which dominate public discourse about the environment only if it moves toward a deliberative discursive jury like research method emphasizing informed discussion leading toward a consensus based on an argument about the public interest

finding common ground between ecological economics and post keynesian economics abstract post keynesian economics and ecological economics have in common that they are considered to be heterodox schools of thought aside from that there has not been a strong connection between them previous books on post keynesian economics contain no chapter on environmental or ecological issues this neglect has led leading ecological economists to criticize post keynesians for succumbing to the same growth paradigm as the neoclassical school this paper argues that the two approaches are complementary in the sense that they each have different strong points ecological economics has correctly pointed out that the growth of the global economy may not be welfare improving anymore whereas post keynesians have gained valuable insights into the functioning of the capitalist growth process to determine the feasibility of a synthesis between the two schools the paper compares their approaches to the problems of production consumption and economic dynamics as well as the associated policy recommendations it shows that on a theoretical level the two schools have much in common but their policy conclusions differ with regard to the desirability of further growth the paper concludes that a synthesis of both approaches may lead to a better understanding of how a capitalist economy operates in a natural environment with limits to growth and to better informed policy advice

competition among sellers who offer auctions instead of prices abstract in this paper we study a large market in which sellers compete by offering auctions to buyers instead of simple fixed price contracts two variants of the model are studied one extends a model first analyzed by wolinsky rev econ stud 55 1988 71 84 in which buyers learn their valuations only after meeting sellers the other variant extends the model of mcafee econometrica61 1993 1281 1312 in which buyers know their valuations before they choose among available auctions the equilibrium array of auctions is characterized for each case and the efficiency properties of the equilibria are analyzed journal of economic literatureclassification numbers d41 d44 d82

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

does commodity money eliminate the indeterminacy of equilibrium abstract previous studies have shown that a random matching model with divisible fiat money and without constraint on agents money inventories possesses a continuum of stationary single price equilibria wallace j econom theory 81 1998 223 conjectures that the indeterminacy can be eliminated by the use of commodity money instead i find that in a similar random matching model with dividend yielding commodity money a continuum of stationary single price equilibria exists when the utility of dividend is not too high this result casts doubt on the conventional belief that the indeterminacy of monetary equilibrium is be caused only by the nominal nature of money

beyond homo economicus evidence from experimental economics environmental policies are generally based on a model of the human actor taken from neoclassical economic theory this paper reports on laboratory experiments suggesting weaknesses in this model and describes alternative models correcting these weaknesses one finding is that economic actors tend to be hyperbolic as opposed to exponential discounters who discount the immediate future at a higher rate than the more distant future another finding is that economic actors are not self regarding but rather in many circumstances are strong reciprocators who come to strategic interactions with a propensity to cooperate respond to cooperative behavior by maintaining or increasing cooperation and respond to free riders by retaliating against the offenders even at a personal cost and even when there is no reasonable expectation that future personal gains will flow from such retaliation we discuss some implications for policy analysis 2000 elsevier science b v all rights reserved

has new york become less competitive than london in global markets evaluating foreign listing choices over time abstract we study the determinants and consequences of cross listings on the new york and london stock exchanges from 1990 to 2005 this investigation enables us to evaluate the relative benefits of new york and london exchange listings and to assess whether these relative benefits have changed over time perhaps as a result of the passage of the sarbanes oxley act in 2002 we find that cross listings have been falling on us exchanges as well as on the main market in london this decline in cross listings is explained by changes in firm characteristics instead of by changes in the benefits of cross listing we show that after controlling for firm characteristics there is no deficit in cross listing counts on us exchanges related to sox investigating the valuation differential between listed and non listed firms the cross listing premium from 1990 to 2005 we find that there is a significant premium for us exchange listings every year that the premium has not fallen significantly in recent years and that it persists when allowing for time invariant unobservable firm characteristics in contrast no premium exists for listings on london s main market in any year firms increase their capital raising activities at home and abroad following a cross listing on a major us exchange but not following a cross listing in london our evidence is consistent with the theory that an exchange listing in new york has unique governance benefits for foreign firms

cognitive and institutional perspectives of eco efficiency the paper sketches out a theoretical framework for analysing the interplay between eco efficiency cognition and institutions it derives from analytical shortfalls of the prevailing literature which features strongly engineering and business economics by using insights from new institutional economics from cognitive science and partly from evolutionary economics it emphasises the role cognition and institutions play in the adoption of green technologies by firms a cognitive perspective derives from recent research on simple heuristics and context based rationality it is proposed that those findings can serve to analyse decision making of individual actors respectively firms and thus should complement economic analysis a second proposition is that eco efficiency and normative rules such as a factor four strongly rely upon institutions i e the ability of institutions to evolve over time and the development of those institutions that are most appropriate to enhance technological change in this regard business institutions and competition are crucial but regulatory needs remain in order to safeguard continuity of knowledge creation the framework allows for an analysis why overall adoption of eco efficiency still can be considered relatively slow and why some markets and firms are far ahead as a brief case study the article reflects upon german waste law s ability to enhance eco efficiency

how to be an ecological economist abstract to answer the question how to be an ecological economist we must start by defining the field of ecological economics mainstream economics altogether lacks the concepts required to deal adequately with nature justice and time it was the absence of these three concepts in this otherwise great social science that led to the establishment of ecological economics the interest in nature justice and time is its defining characteristic the main thesis of this paper is that our field is a fragile institution and that the professional existence of an ecological economist is no less fragile however this very fragility also represents freedom scope for free thinking conceptualising and research nevertheless to be able to really use and in turn enjoy the full scope of this freedom an ecological economist needs certain specific characteristics in particular what is termed in the german philosophical tradition urteilskraft and in english power of judgement a description of these characteristics is developed in this paper providing an answer to the question how to be an ecological economist

the london stock exchange s aim experiment regulatory or market failure a discussion of gerakos lang and maffett abstract the conference paper by gerakos lang and maffett 2013 provides reliable descriptive evidence on the post ipo performance of firms listing on the london stock exchange s alternative investment market aim their findings are consistent with both a failure of private sector regulation and incorrect market expectations about aim s investor protections in this discussion of gerakos et al 2013 i highlight the strengths and limitations of their conference paper summarize how various regulatory and market factors could produce the observed systematic under performance of aim offerings and outline paths for future research on the topic

a unified framework for monetary theory and policy analysis search theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential however tractable versions of these models typically make strong assumptions that render them ill suited for monetary policy analysis we propose a new framework based on explicit micro foundations within which macro policy can be studied the framework is analytically tractable and easily quantifiable we calibrate the model to standard observations and use it to measure the cost of inflation we find that going from 10 percent to 0 percent inflation is worth between 3 and 5 percent of consumption much higher than previous estimates

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

changing concepts of land in economic theory from single to multi disciplinary approaches abstract the role of land in economic theory is surveyed both from a conceptual and historical perspective land has been incorporated in economic theories in various ways originally land used by agriculture was the main motivation for an economic treatment of land this was gradually extended with various other land use categories neoclassical economic theory gave less attention to land use generally regarding land as a production factor of relatively little importance nevertheless specialized sub fields within economics such as regional and urban economics met the demand for explicit spatial analysis including land use considerations attention for environmental and resource problems has stimulated new perspectives on and conceptualizations of land in economic analysis this involves the interaction with other disciplines as well as the use of spatially disaggregated methods of analysis awareness of the richness of ideas on land in economic theory can contribute to enhanced environmental research

pricing and matching with frictions suppose that n buyers each want one unit and m sellers each have one or more units of a good sellers post prices and then buyers choose sellers in symmetric equilibrium similar sellers all post one price and buyers randomize hence more or fewer buyers may arrive than a seller can accommodate we call this frictions we solve for prices and the endogenous matching function for finite n and m and consider the limit as n and m grow the matching function displays decreasing returns but converges to constant returns we argue that the standard matching function in the literature is misspecified and discuss implications for the beveridge curve

on the role of tax subsidy scheme in money search models this article investigates the roles of policy in search models with divisible money recently real indeterminacy of stationary equilibria has been found in both specific and general search models with divisible money thus if we assume the divisibility of money it would be quite difficult to make accurate predictions of the effects of simple monetary policies therefore in this article we introduce a certain tax subsidy scheme and show that this is effective in selecting a determinate efficient equilibrium in other words for a given efficient equilibrium and for any real number 0 a certain tax subsidy scheme induces a locally determinate equilibrium within the neighborhood of the given equilibrium moreover the size of the tax subsidy can be arbitrarily small

do workers prefer increasing wage profiles we present survey data challenging the assumption implicit in analyses of labor supply that all else being equal workers prefer declining over increasing wage profiles we test several explanations for our results including that a there is something special about wages e g their association with productivity as opposed to other types of payments that induces the preference for increasing wages b utility depends not only on absolute levels of consumption but also on changes in consumption over time and c respondents who prefer increasing wage profiles are irrational and would change their behavior if the rationale for preferring declining wages were explained

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

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

an empirical study of the determinants of green party voting i empirically study the determinants of individuals green voting behavior for this i make use of three datasets from germany a panel dataset and two cross sectional datasets the empirically strongest determinants are the voters attitude or distance to nuclear sites the level of schooling and net income i show that those voters with deviant attitudes or alternative world views are more likely to vote green a result of the fact that the green party has always had the position of a protest party i find little role for demographic variables like gender marital status or the number of children this is in contrast to the stated preference literature age plays a role for explaining voting behavior only insofar as it proxies for health

money is memory abstract this paper examines the sets of feasible allocations in a large class of economic environments in which commitment is impossible following myerson 8 the standard definition of feasibility is adapted to take account of the lack of commitment the environments feature either memory or money memory is defined as knowledge on the part of an agent of the full histories of all agents with whom he has had direct or indirect contact in the past money is defined as an object that does not enter utility or production functions and is available in fixed supply the main proposition is that any allocation that is feasible in an environment with money is also feasible in the same environment with memory depending on the environment the converse may or may not be true hence from a technological point of view money is equivalent to a primitive form of memory journal of economic literature classification numbers e40 c73 d82

liquidity a new monetarist perspective this essay surveys the new monetarist approach to liquidity work in this literature strives for empirical and policy relevance plus rigorous foundations questions include what is liquidity is money essential in achieving desirable outcomes which objects can or should serve in this capacity when can asset prices differ from fundamentals what are the functions of commitment and collateral in credit markets how does money interact with credit and intermediation what can and should monetary policy do the research summarized emphasizes the micro structure of frictional transactions and studies how institutions like monetary exchange credit arrangements or intermediation facilitate the exchange process

environmental sustainability as the first principle of distributive justice towards an ecological communitarian normative foundation for ecological economics abstract the ecological economic concern with environmental sustainability embodies the normative orientations of the field this concern is foremost a matter of distributive justice the definition of which determines the relevance of the appropriate scale and efficient allocation criteria yet it would appear that the discipline lacks a shared internally consistent set of ethical premises by which this concern might be legitimized various authors have embraced a rawlsian conception of liberal justice as the appropriate banner for ecological economics in place of the consequentialist libertarian foundations of neoclassical economics including environmental economics it is argued here that this is insufficient in so far as it is premised on a vision of a discrete self sufficient economic actor instead it is posited that an ecological economic ethic must proceed from an understanding of the economic actor as community member a recognition implicit in recent ecological economic contributions focused on discourse ethics and deliberative democracy an ecological communitarian conception of distributive justice which views the well being of the individual as inseparable from the integrity of its implicate mutually constituting human and non human natural communities is advanced as the appropriate basis for the ecological economic world view in this light the thermodynamic foundations of ecological economics are seen to provide the necessary departure point for normative decision making oriented towards ensuring sustainability in economic organization

bridging theories on environmental governance insights from free market approaches and institutional ecological economics perspectives abstract due to methodological problems and their practical limitations the criticism of neoclassical environmental economics is increasing the goal of this paper is to stress the differences and similarities between the two competing alternative approaches institutional ecological economics and free market approaches to environmental protection to encourage their interactions towards a possible synthesis in the future

contingent prices and money price posting with directed search is a widely used trading mechanism coles and eeckhout showed that if sellers are allowed to post prices contingent on realized demand instead of one price then there is real market indeterminacy in this article we fit this contingent price posting protocol into a monetary economy we show that as long as holding money is costly there exists a unique equilibrium rather than a continuum in this equilibrium sellers post a low price for when the buyer is alone a high price for when several buyers show up and buyers randomize between sellers and money holdings

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

open market operations abstract in an open market operation the central bank swaps currency for bonds we show how injecting money in this way is different from transfers the way policy is usually formulated the model captures liquidity explicitly by modeling the roles of assets in frictional exchange under various specifications for market structure and the acceptability or pledgeability of assets we discuss implications for the fisher and quantity equations the possibility of negative nominal yields liquidity traps and market segmentation when liquidity is endogenized using information theory multiple equilibria emerge with different policy predictions interest on reserves and quantitative easing are discussed

what is ecological economics ecological economics addresses the relationships between ecosystems and economic systems in the broadest sense these relationships are the locus of many of our most pressing current problems i e sustainability acid rain global warming species extinction wealth distribution but they are not well covered by any existing discipline environmental and resource economics as it is currently practiced covers only the application of neoclassical economics to environmental and resource problems ecology as it is cur rently practiced sometimes deals with human impacts on ecosystems but the more common tendency is to stick to natural systems ecological economics aims to extend these modest areas of overlap it will include neoclassical environmental economics and ecological impact studies as sub sets but will also encourage new ways of thinking about the linkages between ecological and economic systems we have chosen the name ecological economics for this area of study because it implies a broad ecological interdisciplinary and holistic view of the problem of studying and managing our world the earth from space cover of the journal reflects this global holistic perspective we did not intend to imply with the ordering of the two words in the title that the journal is mainly an economics journal it is intended to be a new approach to both ecology and economics that recognizes the need to make economics more cognizant of ecological impacts and dependencies the need to make ecology more sensitive to economic forces incentives and constraints and the need to treat integrated economic ecologic systems with a common but diverse set of conceptual and analytical tools there was much discussion of other possible names such as economic ecology or ecology and economics or some conjoining of the two words that to me end up being confusing tongue twisters like ecolnomics or econology but ecological economics seemed to get closest to the mean ing we desired while still being evocative to the uninitiated
