the early history of modern ecological economics abstract this paper provides a historical perspective for the discussion on ecological economics as a special field of research by studying the historical background of ecological economics the present discussions and tensions inside the field might become easier to understand and to relate to the study is inspired by other studies of the emergence of new research areas done by sociologists and historians of science and includes both cognitive and social aspects macro trends and the role of individuals the basis for the paper is a combination of literature studies and interviews with key researchers from the field the story opens with the emergence of the new environmental agenda in the 1960s which was influenced by the scientific development in biology and ecology then it is outlined how the environmental challenge was met by economics in the 1960s around 1970 the basic ideas of ecological economics were given modern formulations but it took a long gestation period from the beginning of the 1970s to the end of the 1980s before ecological economics took shape during this gestation period the personal relationships between the actors were formed and the meetings that were decisive for the formal establishment of ecological economics took place

sustainable de growth mapping the context criticisms and future prospects of an emergent paradigm article i nfo sustainable de growth is both a concept and a social grassroots northern movement with its origins in the fieldsofecologicaleconomics socialecology economicanthropologyand environmentalandsocialactivistgroups this paper introduces the concept of sustainable de growth by mapping some of the main intellectual influences fromthese fields with special focus on the francophone and anglophone thinking about this emergent notion we propose hypotheses pertaining to the appeal of sustainable de growth and compare it to the messages enclosed within the dominant sustainable development idea we scrutinize the theses contradictions and consequences of sustainable de growth thinking as it is currently being shaped by a heterogeneous body of literature and as it interacts with an ample and growing corpus of social movements we also discuss possible future paths for the de growth movement compared to the apparent weakening of the sustainable development paradigm

material flows vs natural capital what makes an economy sustainable abstract in the discourse about sustainable development constant natural capital is frequently referred to as a criterion for ecological sustainability but what is natural capital the concept will be analyzed by presenting arguments in favour of using the term and different versions of sustainability strong and weak subsequently a critique of the natural capital concept is brought forward from an ecological as well as from an economic perspective following this critique the use of material inputs and the material input per unit of service mips as a measure for the environmental impact potential is suggested dematerialisation is understood to be an alternative management rule for sustainability in conclusion a change of perspective is proposed due to the conceptual and measurement problems associated with the constant natural capital criterion which refers to a stock it seems more reasonable from a scientific as well as from a practical perspective to add flows i e material inputs to a decision criterion for whether a development is sustainable or not

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

stochastic dominance and mean variance measures of profit and loss for business planning and investment in this paper we first extend the stochastic dominance sd theory by introducing the first three orders of both ascending sd asd and descending sd dsd to decisions in business planning and investment to risk averse and risk loving decision makers so that they can compare both return and loss we provide investors with more tools for empirical analysis with which they can identify the first order asd and dsd prospects and discern arbitrage opportunities that could increase his her utility as well as wealth and set up a zero dollar portfolio to make huge profit our tools also enable investors and business planners to identify the third order asd and dsd prospects and make better choices to complement the stochastic dominance approach we also introduce an improved mean variance criterion to decisions in business planning or investment on both return and loss for risk averse and riskloving investors we then illustrate the superiority of the present approaches with well known examples in the literature and discuss the relationship between the improved stochastic dominance and mean variance criteria

trends in the development of ecological economics from the late 1980s to the early 2000s abstract as the contributions to ecological economics are very diverse recent years have seen some discussion on both how to delimit the field and in which direction it should develop the intention with this paper is to contribute to the discussion by outlining important trends in the development of the field from the late 1980s to the early 2000s the study is inspired by other studies in the sociology and history of science in particular by the theoretical framework regarding scientific fields as reputational organizations which draws attention to both cognitive and social aspects of the formation of a field the basis for the paper is a combination of literature studies interviews with key researchers in the field and participant observations the paper outlines the characteristic cognitive features of ecological economics at the time of the birth of the field it is then described how the development in ecological economics was influenced by broader social factors during the following years and how the field was shaped by the inflow and outflow of different groups of researchers the emergence of different research programmes is outlined as is the organizational development finally the characteristics of ecological economics are summarized and the future prospects are briefly assessed

the output and welfare effects of government spending shocks over the business cycle how does the output response to a change in government spending vary over the business cycle what are the welfare eects of spending shocks this paper studies the state dependence of the output and welfare eects of shocks to government purchases in a dsge model with real and nominal frictions and a rich scal nancing structure both the output multiplier the change in output for a one dollar change in government spending and the welfare multiplier the consumption equivalent change in welfare for the same change in spending move signicantly across states but tend to co move negatively with one another in an historical simulation the output multiplier is countercyclical correlation with detrended output of 0 4 and strongly negatively correlated with the welfare multiplier correlation between multipliers of 0 9

downward nominal wage rigidity and state dependent government spending multipliers abstract despite much empirical evidence on business cycle dependent government spending multipliers the theoretical channels underlying such results are uncertain in an environment with involuntary unemployment this paper shows that downward nominal wage rigidity which arises only in recessions can generate business cycle dependent government spending multipliers in line with keynesian views a demand stimulus reduces unemployment in recessions and may not drive up inflation and wages as in expansions thus the positive income effects from reduced unemployment and weaker crowding out effects from a smaller increase in the real interest rate enhance the expansionary spending effects in recessions the theoretical implications are largely consistent with existing empirical evidence on business cycle dependent government spending effects on key macroeconomic variables

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

fiscal stimulus in times of high debt reconsidering multipliers and twin deficits we investigate the impact of fiscal stimuli at different levels of the government debt to gdp ratio for a sample of 17 european countries from 1970 to 2010 this is implemented in an interacted panel var framework in which all coefficient parameters are allowed to change continuously with the debt to gdp ratio we find that responses to government spending shocks exhibit strong nonlinear behavior while the overall cumulative effect of a spending shock on real gdp is positive and significant at moderate debt to gdp ratios this effect turns negative as the ratio increases the total cumulative effect on the trade balance as a share of gdp is negative at first but switches sign at higher levels of debt consequently depending on the degree of public indebtedness our results accommodate long run fiscal multipliers that are greater and smaller than one or even negative as well as twin deficit and twin divergence behavior within one sample and time period from a policy perspective these results lend additional support to increased prudence at high public debt ratios because the effectiveness of fiscal stimuli to boost economic activity or resolve external imbalances may not be guaranteed

a matter of opinion how ecological and neoclassical environmental economists and think about sustainability and economics abstract the differing paradigms of ecological and neoclassical environmental economics have been described in various articles and books and are also embedded in different professional associations however we cannot take for granted that the paradigm debates described in the literature are actually mirrored in exactly the same way in the perceptions and opinions of researchers looking at sustainability from an economic perspective this paper presents empirical results from a german case study on how economists and others involved in sustainability research from different schools of thought think about the issues of sustainability and economics how they group around these issues how they feel about the current scientific divide and what they expect to be future topics of sustainability research we analyze the data using cluster analysis based on a literature survey we generated forty sustainability economics related statements and asked 196 sustainability researchers about their degree of agreement or disagreement with these statements in evaluating our survey results we discuss to what extent the clusters that we identified do or do not represent the two schools of thought of ecological and neoclassical environmental economics we also propose some fields of research that can help to bridge the gaps amongst sustainability economics researchers while clearly marking others that are more suitable for a scientific competition of ideas key results of the study are we identify two primary scientific clusters one clearly confirming the existence of the ecological economics school of thought and the other largely capturing the neoclassical environmental view yet there are some surprising exceptions both schools of thought share a conceptual definition of sustainability that is integrative in considering ecological societal and economic dimensions three pillar concept and is geared at preserving the development potentials of society we also find a shared critique of pure economic growth strategies in our sample these shared opinions may provide bridging concepts between the schools of thought also both clusters agree with respect to a wide range of future fields of sustainability economics research yet the research agenda of the ecological economics cluster contains a large number of additional topics primarily related to social distributional and evolutionary aspects of sustainable development strong divides between the clusters that seem to be more suitable for a scientific competition of ideas are primarily related to the question of how to achieve sustainability including appropriate environmental policies

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

do investors like to diversify a study of markowitz preferences we study rankings of completely and partially diversified portfolios and also of specialized assets when investors follow so called markowitz preferences it turns out that diversification strategies for markowitz investors are more complex than in the case of risk averse and risk inclined investors whose investment strategies have been extensively investigated in the literature in particular we observe that for markowitz investors preferences toward risk vary depending on their sensitivities toward gains and losses for example it turns out that unlike in the case of risk averse and risk inclined investors markowitz investors might prefer investing their entire wealth in just one asset this finding helps us to better understand some financial anomalies and puzzles such as the well known diversification puzzle which notes that some investors tend to concentrate on investing in only a few assets instead of choosing the seemingly more attractive complete diversification

why does private consumption rise after a government spending shock recent empirical evidence suggests that private consumption is crowded in by government spending this outcome violates existing macroeconomic theory according to which the negative wealth effect brought about by a rise in public expenditure should decrease consumption

nominal wage rigidity and the rate of inflation using the accurate and extensive data available in the uk new earnings survey this paper investigates the extent to which nominal wages are downwardly rigid and whether such rigidity interferes with necessary real wage adjustments when inflation is low despite the substantial numbers of individuals whose nominal wages fall from one year to the next we find that if long run inflation is one percent higher the number of individuals with negative real pay growth increases by around 1 4 percent this is controlling for the median and dispersion of the real wage change distribution

clearing up the fiscal multiplier morass bayesian prior predictive analysis of five nested dsge models suggests that model specifications and prior distributions tightly circumscribe the range of possible government spending multipliers multipliers are decomposed into wealth and substitution effects yielding uniform comparisons across models by constraining the multiplier to tight ranges model and prior selections bias results revealing less about fiscal effects in data than about the lenses through which researchers choose to interpret data when monetary policy actively targets inflation output multipliers can exceed one but investment multipliers are likely to be negative passive monetary policy produces consistently strong multipliers for output consumption and investment

environmental expenditure spillovers evidence from an estimated multi area dsge model abstract this article constructs and estimates a multi area dynamic stochastic general equilibrium model with a spatial simultaneous equation taking beijing tianjin hebei region in china as an example we explain the dynamic effect of environmental expenditure shock and its spillover effects environmental expenditure has an obvious crowding out effect on consumption and investment in local area but has some positive influences on the economy of external regions over the business cycle environmental expenditure shock in local area can well explain the volatility of real output and social investment in the last 52 quarters however environmental expenditure shocks in external regions have little contribution to the volatility of output and investment in local area one interesting result is that the contribution of environmental expenditure shocks in external regions to the trend of pollution fluctuation is greater than that in local area

the circular economy an interdisciplinary exploration of the concept and application in a global context there have long been calls from industry for guidance in implementing strategies for sustainable development the circular economy represents the most recent attempt to conceptualize the integration of economic activity and environmental wellbeing in a sustainable way this set of ideas has been adopted by china as the basis of their economic development included in both the 11th and the 12th five year plan escalating the concept in minds of western policymakers and ngos this paper traces the conceptualisations and origins of the circular economy tracing its meanings and exploring its antecedents in economics and ecology and discusses how the circular economy has been operationalized in business and policy the paper finds that while the circular economy places emphasis on the redesign of processes and cycling of materials which may contribute to more sustainable business models it also encapsulates tensions and limitations these include an absence of the social dimension inherent in sustainable development that limits its ethical dimensions and some unintended consequences this leads us to propose a revised definition of the circular economy as an economic model wherein planning resourcing procurement production and reprocessing are designed and managed as both process and output to maximize ecosystem functioning and human well being

fiscal stimulus and the role of wage rigidity abstract in this paper we study the impact of an expansion in public spending in an economy characterized by limited asset market participation and sticky wages the flexible wage version of the model implies strong expansionary effects on output and consumption but also a counterfactual increase in real wages the introduction of sticky wages besides being a realistic addition solves this problem and preserves the expansionary effects on output and consumption moreover once we introduce segmentation in the labor market sticky wages are even essential to obtain expansionary effects

regime switching debt and taxation the effects of changes to the tax rate are studied within a framework where an estimated regime switching process for the debt output ratio is embedded in a standard growth model the regime is a hidden state variable so agents face a signal extraction problem consequently agents incorporate the possibility of switching to different fiscal regimes when forming expectations over future taxes decision rules have additional nonlinearity relative to fixed regime models income allocation and the tax elasticity of investment depend on agents inference regarding the regime specifically the tax elasticity can be either positive or negative depending on whether agents perceive a tax reform as an intra regime shock or change in regime

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

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

monetary fiscal policy interactions and fiscal stimulus abstract increases in government spending trigger substitution effects both inter and intra temporal and a wealth effect the ultimate impacts on the economy hinge on current and expected monetary and fiscal policy behavior studies that impose active monetary policy and passive fiscal policy typically find that government consumption crowds out private consumption higher future taxes create a strong negative wealth effect while the active monetary response increases the real interest rate this paper estimates markov switching policy rules for the united states and finds that monetary and fiscal policies fluctuate between active and passive behavior when the estimated joint policy process is imposed on a conventional new keynesian model government spending generates positive consumption multipliers in some policy regimes and in simulated data in which all policy regimes are realized the paper reports the model s predictions of the macroeconomic impacts of the american recovery and reinvestment act s implied path for government spending under alternative monetary fiscal policy combinations

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

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

econ 101 in need of a sustainability transition abstract ecological economics was one of the first of a number of scientific communities to develop transdisciplinary understandings of the sustainability challenges faced by society as a field with economics in its name ecological economics differs from the other communities and should face the particular task of contributing to the development of a new economics for economics to promote sustainability transitions it is not enough to call for more pluralism a new basic structure of economic knowledge should be developed in order to provide the foundation for a sustainability transition to econ 101 this paper argues that the performativity of economics needs to change and proposes a way of structuring econ 101

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

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

can de growth be considered a policy option a historical note on nicholas georgescu roegen and the club of rome abstract at a few months interval georgescu roegen s the entropy law and the economic process 1971 and club of rome s limits to growth 1972 were published both emphasized the dangers of economic growth and both drew negative reactions from mainstream economists relying on archival evidence we show that georgescu roegen and the club of rome developed strategies of mutual support which would present them at first view as natural allies georgescu roegen actually became a member of the club of rome while dennis meadows acknowledged the influence of georgescu roegen s ideas on the team of authors of limits to growth but in the late 70 s the gap widened between georgescu roegen s adamant defense of de growth and the club of rome s less firm view of sustainable growth this paper explores the process leading to the self isolation of georgescu roegen by showing that beyond a shared acknowledgment that economic and biologic systems were interdependent technological optimism and ambitions for the global management of growth were central to the club of rome while georgescu roegen s personal history led him to ignore those practicalities and judge that de growth was inescapable

living to spend another day exploring resilience as a new fourth goal of ecological economics abstract the three main goals of ecological economic theory seek to predict and prevent system breakdowns however chaos theory and human uncertainty ignorance guarantee that shocks breakdowns and catastrophes like covid 19 will increasingly occur due to converging environmental resource crises the challenge then is designing a resilient safe fail economy that can endure adapt to and successfully recover from breakdowns and avoid collapse to date little attention has been paid in ecological economics to the implications of resilience for broader economic decisions affecting the design of global civilization this paper provides a general introduction to resilience and an argument for why it should become a much larger focus of ecological economic research going forward five arguments are advanced for why resilience should not be subsumed under an existing goal including that efforts to build resilience have the potential to both complement and contradict the other three goals especially efficiency the resilience alliance s adaptive cycle highlighting the cost to resilience of increasing scale and complexity meshes readily with ecological economist s own critiques of growth encouraging increased collaboration between these transdisciplines the need to further study these tensions provides justification for adding resilient design as a distinct fourth policy goal to core ecological economic theory

prospect theory and mean variance analysis the experimental results of prospect theory pt reveal suggest that investors make decisions based on change of wealth rather than total wealth that preferences are s shaped with a risk seeking segment and that probabilities are subjectively distorted this article shows that while pt s findings are in sharp contradiction to the foundations of mean variance mv analysis counterintuitively when diversification between assets is allowed the mv and pt efficient sets almost coincide thus one can employ the mv optimization algorithm to construct ptefficient portfolios the markowitz 1952a tobin 1958 mean variance mv rule is probably the most popular investment decision rule under uncertainty in economics and in finance and it is widely employed by both academics and practitioners the strength of the mv analysis is that in the case of normal return distributions the choice of any expected utility maximizing risk averse individual will be according to the mv rule 1 the mv framework is the foundation of the sharpe 1964 lintner 1965 capital asset pricing model capm which is a cornerstone of modern finance moreover the mv framework provides a very important practical procedure for the construction of efficient portfolios while standard economic theory and in particular mv analysis assume expected utility maximization and risk aversion in a breakthrough article kahneman and tversky 1979 show that the actual behavior of individuals systematically and consistently violates these

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

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

towards connecting green economy with informal economy in south africa a review and way forward the informal economy is a vibrant and growing phenomenon offering both opportunities and lessons on resilience and innovation when considering global social economic and environmental challenges resilience and innovation are valuable response strategies the notion of a green economy has similarly inspired a number of ideological geopolitical and institutional responses yet a review of the dominant approach indicates the propensity to undervalue or ignore the informal economy within the context of sustainable development and poverty eradication connecting the informal economy with the green economy is imperative this paper explores possible connections between the green economy and the informal economy in south africa and argues that by engaging the informal economy in discussions on the green economy a more informed policy and planning environment may ensue resulting in more socially equitable and environmentally sustainable development

prospect theory much ado about nothing prospect theory is a paradigm challenging the expected utility paradigm one of the fundamental components of prospect theory is the s shaped value function the value function is mainly justified by experimental investigation of the certainty equivalents of prospects confined either to the negative or to the positive domain but not of mixed prospects which characterize most actual investments we conduct an experimental study withmixed prospects using for the first time recently developed investment criteria called prospect stochastic dominance psd and markowitz stochastic dominance msd we reject the s shaped value function showing thatat least 62 76 of the subjects cannot be characterized by such preferences we find support for the markowitz utility function which is a reversed s shaped function exactly the opposite of the prospect theory value function it is possible that the previous results supporting the s shaped value function are distorted because the prospects had only positive or only negative outcomes presenting hypothetical situations which individuals do not usually face and which are certainly not common in financial markets

equilibrium in a production economy with an income tax this paper develops a method to study an infinite horizon production economy distorted by a state dependent income tax this setting permits taxes to depend on the capital stock an endogenous state variable and thus captures situations where the evolution for capital and taxes is jointly determined to solve this model the consumption function is represented as a fixed point of a nonlinear monotone operator that is defined such that its nth iteration computes the consumption function n steps away from the horizon for a corresponding finite horizon economy the oparator s monotonicity is exploited in proving the existence of and constructing an equilibrium copyright 1991 by the econometric society

nonlinear adventures at the zero lower bound abstract in this paper we argue for the importance of explicitly considering nonlinearities in analyzing the behavior of the new keynesian model with a zero lower bound zlb of the nominal interest rate to show this we report how the decision rules and the equilibrium dynamics of the model are substantially affected by the nonlinear features brought about by the zlb we also illustrate a tension between the length of a spell at the zlb and the drop in consumption there

stochastic dominance via quantile regression with applications to investigate arbitrage opportunity and market efficiency abstract tests for stochastic dominance constructed by translating the inference problem of stochastic dominance into parameter restrictions in quantile regressions are proposed they are variants of the one sided kolmogorov smirnoff statistic with a limiting distribution of the standard brownian bridge the procedure to obtain the critical values of our proposed test statistics are provided simulation results show their superior size and power they are applied to the nasdaq 100 and s p 500 indices to investigate dominance relationship before and after major turning points results show no arbitrage opportunity between the bear and bull markets our results infer that markets are inefficient and risk averters are better off investing in the bull rather than the bear market

debt dependent effects of fiscal expansions abstract economists often postulate that fiscal expansions are less stimulative when government debt is high than when it is low empirical evidence however is ambiguous using a nonlinear neoclassical growth model we show that the difference in government spending effects between high and low debt environments depends on the wealth effect on labor supply and on whether the government uses taxes or spending to retire debt because of interrelated state variables structural var estimations conditioning on debt alone can fail to isolate debt dependent effects also uncertainty on when the government will conduct fiscal consolidations generates wide confidence bands for spending multipliers further complicating efforts to estimate debt dependent government spending effects

the neoclassical production function as a relic of anti george politics implications for ecological economics abstract widespread support for henry george s land tax proposal prompted a backlash from wealthy landowners who focused their political efforts on tax policy the backlash corresponded chronologically with the development of neoclassical economics and land barons became active in the establishment of academic economics institutions in the united states whereas the classical economists frequently referred to the factors of production as land labor and capital neoclassical textbooks appearing in the 20th century increasingly ignored land and provided a production function y f k l in which capital and labor were the only factors explicitly identified neoclassical authors had several possible reasons for using a two factor production function but the political influence on neoclassical economics during its formative stages was conducive to avoiding reference to land when discussing factors of production an emphasis on land would have invited scrutiny of land rents for tax purposes ecological economics has evolved as a response to the shortcomings of neoclassical economics in dealing with the environmental perils of economic growth one of those shortcomings is the capital labor production function which hides the importance of land and natural resources ecological economists have developed production functions that are more ecologically oriented and one of them is explained herein

theories of risk testing investor behaviour on the taiwan stock and stock index futures markets investor behavior towards risk lies at the heart of economic decision making in general and modern investment theory and practice in particular this paper uses both the mean variance mv criterion and stochastic dominance sd procedures to analyze the preferences for four of the most widely studied investor types in the taiwan stock and stock index futures market we find that risk averters concave utility function prefer spot to futures whereas risk seekers convex utility function prefer futures to spot our findings also show that investors with s shaped utility functions prefer spot futures to futures spot when markets move upward downward finally our results imply that investors with reverse s shaped utility functions prefer futures spot to spot futures when markets move upward downward these results are robust with respect to sub periods spot returns including dividends and diversification although we do not check whether risk averters risk seekers and investors with s shaped and reverse sshaped utility functions actually exist in the market we do show that their existence is plausible the implications of our findings on market efficiency and the existence of arbitrage opportunities are also discussed in this study

assessing the degrowth discourse a review and analysis of academic degrowth policy proposals abstract debates on ecological and social limits to economic growth and new ways to deal with resource scarcity without compromising human well being have re emerged in the last few years central to many of these is a call for a degrowth approach in this paper a framework is developed to support a systematic analysis of degrowth in the academic literature this article attempts to present a clearer notion of what the academic degrowth literature explores by identifying organising and analysing a set of proposals for action retrieved from a selection of articles the framework is applied to classify proposals according to their alignment to ecological economics policy objectives sustainable scale fair distribution and efficient allocation type of approach top down versus bottom up and geographical focus local national or international a total of 128 peer reviewed articles focused on degrowth were reviewed and 54 that include proposals for action were analysed the proposals identified align with three broad goals 1 reduce the environmental impact of human activities 2 redistribute income and wealth both within and between countries and 3 promote the transition from a materialistic to a convivial and participatory society the findings indicate that the majority of degrowth proposals are national top down approaches focusing on government as a major driver of change rather than local bottom up approaches as advocated by many degrowth proponents the most emphasised aspects in the degrowth literature are related to social equity closely followed by environmental sustainability topics such as population growth and the implications of degrowth for developing nations are largely neglected and represent an important area for future research moreover there is a need for a deeper analysis of how degrowth proposals would act in combination

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

is there a fiscal free lunch in a liquidity trap this paper uses a dsge model to examine the eects of an expansion in government spending in a liquidity trap the spending multiplier can be much larger than in the normal situation if the liquidity trap is very persistent and scal stimulus can be rapidly implemented moreover the budgetary costs may be minimal as the large response of output boosts tax revenues allowing for something close to a scal free lunch however we caution that the multiplier may be much smaller under plausible implementation lags for many types of public spending and or if the liquidity trap lasts less than two years in addition because the marginal impact of scal expansion decreases in the scale of the outlay it is crucial to distinguish between average and marginal multipliers

fiscal multipliers in recessions standard business cycle models have difficulties generating large state dependent fiscal multipliers employing a model of costly financial intermediation based on curdia woodford we show that fiscal multipliers can be strongly state dependent fiscal expansions during recessions may lead to multiplier values exceeding two while similar expansions during economic booms would produce values falling short of unity this pattern obtains if the spread the financial friction is more sensitive to fiscal policy during recessions than during expansions a feature that is present in the data our results are consistent with recent empirical work documenting the state contingency of multipliers

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

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

estimating fiscal multipliers news from a non linear world we estimate non linear vars to assess to what extent fiscal spending multipliers are countercyclical in the us we deal with the issue of non fundamentalness due to fiscal foresight by appealing to sums of revisions of expectations of fiscal expenditures this measure of anticipated fiscal shocks is shown to carry valuable information about future dynamics of public spending results based on generalised impulse responses suggest that fiscal spending multipliers in recessions are greater than one but not statistically larger than those in expansions however non linearities arise when focusing on extreme events that is deep recessions versus strong expansionary periods

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

the identity of ecological economics retrospects and prospects the paper first reveals the relevance of ecological economics in the time of a triple crisis ecological social and economic and promotes it as a distinct paradigm comprised of two interconnected and interdependent aspects the qualitative framework within which it operates and the quantitative models and techniques it uses to observe ecosystem resilience measure progress towards sustainability and evaluate policies while acknowledging the progress that has so far been made the paper argues that divergences in understanding the meaning and content of ecological economics hinder its effectiveness and influence on real world policy making and calls for a unified framework as a common ground that would strengthen the field and direct research the implication of this position then follows pointing out what has so far been missing from the ecological economics analysis and what should be done for it to become a more problem oriented and policy relevant alternative copyright oxford university press

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

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
