The EconomicsEnvironment Relationship: Neoclassical, Institutional, and Marxist Approaches FIKRET ADAMAN AND BEGUM OZKAYNAK ntroduction The importance of the environment for economic activity and, in tum, the impact of economic activity on nature, have motivated economists to include the analysis of the relationship between economics and the environment in their research agenda since economics became a discipline. Given the existence of different schools of thought within economics-at times complementary and at times conflicting-the debate over the way in which this relationship should be conceptualized and analyzed has a history as old as that of the interest itself. Thus, it is not surprising to encounter studies that evaluate, from a historical perspective, the application of the tools of economics to environmental issues.! Although these studies provide rich descriptions of the history of environmental concerns within the discipline of economics, their common aim appears limited to defining positions with respect to the environmental issues of a rich spectrum of contributors. A complementary effort might involve explicit consideration of competing economic approaches to the economics-environment relationship. Such an undertaking would distinguish interrelated issues from one another according to epistemological standpoints, analytical approaches or operative categories and instruments of intervention.2 With this as our motivation, we propose to critically review the ways in which the three contemporary economic approaches-the Neoclassical, the Institutional, I Studies in Political Economy 69, Autumn 2002 L.. 109 Studies in Political Economy and the Marxist theories-eonceptualize the relationship of economics and the environment. The debate about environmental issues within economics can be reduced to different positions on three interrelated dimensions: the definition of environmental degradation itself (thus determining which economic actions should be categorized as causing degradation and which not); the economic explanation of the raison d'etre of this (however defined) degradation, and ways to slow down/halt/reverse this (however defined and explained) degradation. The first aim of this paper is to position, via these three dimensions, the three contending economic approaches with respect to their conceptualization of the economics-environment relationship. The second aim of this paper is to compare and contrast these three major approaches with an attempt at formulating the modus vivendi of an environmentally attuned economy. Our evaluation will indicate that both the definition and the scope of environmental problems and their proposed solutions should be conceptualized at a societal level. The critical survey will lead us, furthermore, to the conclusion that only a holistic methodology will enable the researcher to take full account of the complexity and multidimensionality of social and economic structures and natural systems. Thus, instead of assuming the existence of atomistic "actors" exercising their instrumental rationality, we suggest that individuals be considered with explicit reference to their social, political, and environmental milieus, as well as to their past and current experiences. We will finally argue that if this ontological and methodological standpoint were to be accepted in a society where participatory decision-making mechanisms are ensured, then economic and related spheres could be more easily organized in ways that are attuned to the environment. The structure of the paper is as follows: after outlining the three contenders' positions vis-a-vis the economics-environment relationship through the three dimensions set out, we will evaluate them comparatively and attempt to set out the contour of an environmentally attuned economy. Schools of Economic Thought on the Economics-Environment Relationship Of the contending models, the Neoclassical provides the most complete and detailed picture of the 110 Adaman and Ozkaynak/Economics-Environment economy-environment relationship. Glorifying the couplet of methodological individualism and market relations, Neoclassical theory locates the economic explanation of the degradation of nature-s-expressed operationally in terms of the overuse of natural resources and the waste disposal above the ecosystem's assimilative capacity-in a lack of markets for environmental goods and services. The non-existence of markets is thus regarded as being responsible for the failure of people to recognize the otherwise positive prices of environmental goods and services. Yet, this malady-the source of so-called "market failures"-is also seen to be remediable via institutional set-ups. Within this framework, the overuse of natural resources is seen, on one hand, as the consequence of a lack of welldefined property rights as a result of which (renewable and non-renewable) resources become readily available too cheaply to its current users. Hardin called this problem "the tragedy of the commons: 'Ruin is the destination toward which all men rush, each pursuing his own best interest in a society that believes in the freedom of the commons. Freedom in a commons brings ruin to all. "'3 Pollution of the environment, on the other hand, is understood as occurring because the economic agents who undertake activities of production and consumption enjoy a complete lack of liability to third parties who suffer the environmental damages imposed upon them. This situation is regarded as one of externalities, a corollary of which is that the "social" and "private" costs of an economic activity can be quite different from each other.' Neoclassical theory states that environmental degradation will translate itself into a loss of efficiency. The argument is that both "rapid" extraction rates and "externalities" will inevitably bring about a departure from optimum allocation of resources (the so-called Pareto efficiency). To restore efficiency, the theory seeks, first, to determine the "optimal" rate of the use of natural resources-the rate that will maximize the social collective return (and in a dynamic state this will be expressed in present value). Secondly, in the case of externalities, the theory dictates the internalization of environmental costs through balancing economic gains with the environmental costs accrued from undertaking economic activities. Two solutions are proposed to restore efficiency. The first, known as the Coasian theorem, advocates the introduction of 111 Studies in Political Economy appropriate property rights. When property rights are clearly defined, compensations change hands according to which party holds the natural resource, ensuring an efficient degree of economic activity. The second solution proposes introducing a regulatory agency that can initiate corrective measures designed to achieve optimality by either prohibiting/reducing environmentally damaging activities through the setting of standards and quotas (known as command-and-control approaches), or by designing incentive-based mechanisms, such as pollution taxes or emissions-trading regimes.> It is self-evident that for implementing and enforcing both sets of mechanisms for restoring efficiency, the existence of a social guardian/government that works selflessly needs to be assumed a priori. Neoclassical theory acknowledges the difficulty of making such an assumption; either such a body may simply not exist (as in the case of environmental problems of global scale, such as ozone depletion), or central/local governments may simply "fail." Regarding the first possibility: when a government-like institution is absent (who, for example, has the ownership of the ozone layer other than all governments?), open access problems a la Hardin will re-emerge. Regarding the second possibility, when networks between governments and interest groups that ask for particularistic favours happen to be binding, favouritism rather than efficiency will likely dictate the outcome.s The issue of government failures and their impacts on environmental policies can best be addressed, according to conventional theory, by explicitly considering the strategic behaviours of individuals and government officers. At any rate, the extensive body of literature on the "public choice" that considers such strategic interactions applies mutadis mutandis to environmental regulation cases as well.? The solutions offered, under the assumption that governments do exist and are immune to failures, are of course contingent on measuring the value assigned to environmental goods. The theory assumes that individuals assign values to the environment (with the distinction among "use," "altruistic," "bequest," and "existence" values) and that underlying these values are exogenously given individual preferences.f Since markets do not exist for environmental goods and services, the theory calls for the estimation of their values. 112 Adaman and OzkaynaklEconomics-Environment Although their accuracy is discussed within the theory itself, there now exists a body of techniques for measuring individuals' valuations.? One of the techniques most used is the socalled "contingent valuation" method, according to which individuals who are considered "relevant" are asked to reveal their maximum willingness to pay for a project that will improve the quality of a specific environmental good (say, cleaning up a lake), or their minimum willingness to accept a project that will lower the environmental quality of a specific good (say, the pollution of a lake). Individuals' revealed valuations are then aggregated to estimate the value of a specific environmental good. Once valuation is assumed to be established for projects which will bring about environmental damages and economic gains over a period of years, all kinds of actual and future costs and benefits associated with economic activities can be computed with an a priori chosen discounting factor, and optimality calculations in the form of "cost-benefit," or "cost-effectiveness," analyses can then be conducted. to In addition to the efficiency problem caused by extraction rates and levels of production and consumption, Neoclassical theory acknowledges the existence of a justice (equity) problem that reveals itself in the relative positions of perpetrators and victims, and which can assume either an intragenerational or an intergenerational aspect, depending on whether or not perpetrators and victims live in the same span of time)! When the justice issue is raised, however, conventional theory either bypasses it on the grounds that the theory itself is value-free whereas the justice issue is by definition value-laden, or refers to the field of public choice that investigates problems associated with aggregating individual preferences (regarding different states of distributional justice) in order to come up with a social one. Let us, by explicitly referring to the three-dimensionality yardstick described in the Introduction, reiterate the theory's position vis-a-vis environmental issues. Regarding the first dimension, environmental degradation is defined through glimpses of separate, autonomous individuals, each of whom is assumed to have an ordering of goods and services, including those pertaining to the environment. The value of a specific environmental good is determined by aggregating the 113 Studies in Political Economy valuations of all concerned individuals. Should the value of the environmental good in question turn out to be greater than the economic value-added that can be obtained at the cost of destroying/using the environmental good in question, then the theory labels it a degradation. The theory, secondly, offers the lack of markets for environmental goods and services as the economic cause of environmental degradation. Finally, regarding the third dimension, the theory proposes, first, to discover through a set of valuation techniques the values individuals assign to environmental goods in order to compare economic profits with their accompanying environmental costs, and, secondly-once the appropriate efficient level of environmental protection is identified-to achieve this level of optimality via a set of mechanisms (commandand-control or incentive-based). Following the presentation of the contours of Neoclassical theory as applied to the economics-environment relationship, it may be time to ask whether it is vulnerable to internal criticism. Here, we might address two problematic areas: the first has to do with the weaknesses associated with the proposed solutions to environmental problems. On the one hand, it is always possible to assign property rights to environmental goods, as Coase would have us do, and still observe no improvement in environmental quality. We will then correctly suspect the existence of high transaction costs of bargaining between concerned parties, but since such transaction costs can never be observed a priori, we find ourselves in a tautological world. On the other hand, were we to follow a regulatory approach, we should presuppose not only the possibility of measuring individuals' valuations of environmental goods as accurately as possible, but also the existence of an omnipotent and selfless enforcer as already mentioned. The theory, in fact, acknowledges the dubious nature of both these assumptions: regarding the first, the techniques used for extracting individuals' preferences for environmental goods demand too strong a set of assumptions and/or require the existence of too detailed a data set; regarding the second, the remedy for government failures is widely regarded as too great a challenge.l? The second problematic area involves justice issues. The first dimension has to do with the fact that, since nearly all policies that aim to deal with environmental issues have an 114 Adaman and Ozkaynak/Economics-Environment impact on income distribution (directly or indirectly), the choice of which distributional outcome is most desirable is contingent on how individuals' preferences for various distributional policies are aggregated, so that one distributive maxim could be applied at the end. But here the theory acknowledges an unavoidable cul-de-sac: Arrow's wellknown theorem on the impossibility of aggregation points out that no "social choice function" (viz. aggregation mechanism) exists that can satisfy a minimum set of aggregation properties that one would definitely like to have.r' The second dimension has to do with the fact that a different initial distribution of endowments (and income) is likely to generate different environmental prices. When the distribution is altered, the pattern of demand, and thus the pattern of prices, will also be altered, affecting the whole valuation system.tThe critiques originating within the theory itself having been addressed, we now turn to the critiques from outside. In the entire Neoclassical setting, the social, cultural, and political status of the individual is reduced to that of an economic agent (in the form of a consumer/producer/resource owner) and, as such, the theory falls into a tautological trap: whatever choice is made, this can be formulated as furthering individuals' interests. But a full critique of Neoclassical theory can, of course, only be given by a presentation of the contending positions. This is where our paper is heading. The Institutional school, the second contender, which is itself historically linked to writers as diverse as Galbraith, Kapp, Marx, Mitchell, Myrdal, Schumpeter, K. Polanyi, J. Robinson, and Veblen, accepts the view that organizations, institutions, habits, values, norms, and rules-all both causes and consequences of the power structure, and socialized behaviour of individuals and subgroups-have substantive impacts on economic performance (expressed as, inter alia, resource allocation, income distribution, growth, division of labour and its remunerationj.i> In this perspective, not only is a holistic method chosen and the endogeneity of individual preferences assumed to play an important role in explaining social and economic processes, but also public debates and networking are regarded as instrumental complements to the market mechanism, in forming a society's value system. The Institutional approach, thus, recognizes "the centrality of 115 Studies in Political Economy participatory democratic processes to the identification and evaluation of real needs, instead of a utilitarian outlook which separates considerations of means from those ends, and judgments of fact from those of value, and which ignores social relations, conflicts and inequalities between agents."16 Kapp, one of the key figures of the school, aptly formulated the core of the Institutional approach as "the denial that economic processes (of production, distribution, and reproduction) can adequately be understood and analyzed as closed, i.e., self-contained and self-sustaining, systems isolated from a social and physical 'environment' of which the economic system is a part and from which it receives important inputs and with which it is related through manifold reciprocal interdependencies."17 If the economy were not conceptualized as embedded within the social life, according to the Institutional approach, then not only should the motives that predispose the individual be designated merely as instrumental, but it would also be impossible to see how the individual's preferences are formed and, thus, how costs and benefits are computed. Rather than accept a reductionist and mechanistic methodology, the Institutionalists assume a holistic point of view, emphasizing the social and historical context to bypass the tautological gap mentioned above.l'' This perspective further advocates that the economy be conceived as a cumulative and evolutionary process, one in which both individuals and societies face radical uncertainty. It thus recognizes the legitimacy of different value-commitments in dealing with the more uncertain aspects of social, economic as well as environmental issues, and calls for an interdisciplinary research agenda, arguing that the entwined relationship between the individual, nature, and society be investigated with respect to their entwined relationships. More specifically, when addressing the production side, the Institutional approach aims to consider explicitly the forces that promote technological transformation, the interactive process of production and exchange, networking among firms and other social institutions, and internal organizational issues. This standpoint necessitates, first, the investigation of the "real" purposes of production units, instead of simply assigning them the Neoclassical maxim "profit maxi116 Adaman and Ozkaynak/EconomicsoEnvironment mization."19 Second, and in a related way, the firms' developmental paths and their organizational modalities have been questioned and evaluated. Within this framework, the emphasis seems to have fallen on the ways in which a firm's stocks of knowledge are articulated and mobilized in the course of interaction with the external economic environment. It is further suggested that what is learned during this interactive processes is then "loaded" into the firm's "routines."2o Hodgson neatly summarizes the Institutional position by claiming that the learning process is to be seen as both developmental and reconstitutive-in contrast to the Neoclassical school that perceives learning simply as "the cumulative discovery of pre-existing 'blueprint' information, or Bayesian updating of subjective probability estimates in the light of incoming data."21 With respect to the economics-environment relationship, this perspective recognizes, above all, that the three broad headings of economic, social, and ecological dimensions are inseparable, as aptly put forward by O'Connor et al.: "[T]he economic domain of commodity production and consumption can be deemed part of the social domain of activities establishing and renewing relationships and institutional forms; and the social category includes culture which bears on the ways that features of the natural world are classified and appraised. "22 The Institutional approach considers two dimensions when applied to environmental issues. The first deals with the impact of power structures and power relations (at local/national/international levels) on environmental issues and regimes. This approach emphasizes the claim that environmental conflicts are not only about values but, above all, about power and interests with the further clarification that an unequal distribution of power is usually conducive to an increase in environmental degradation.P The second dimension is found in the design of institutional settings that directly and indirectly affect environmental policies. In this regard, we acknowledge a recent attempt to approach environmental issues from an Institutional perspective under the rubric of "Ecological Economics. "24This understanding proposes various deliberative mechanisms and procedures concerning decisions that have an environmental impact; its proponents 117 Studies in Political Economy argue in favour of using a multicriteria analysis that would involve political and economic as well as moral, scientific, and cultural inputs. The Institutional perspective, as signalled, posits a set of social norms and principles in addition to market institutions, to create harmony in society; it looks for possible· ways of attaining consensus among the holders of different views and approaches, by way of deliberative social institutions, in order to facilitate interactive debates and negotiations among individuals.e In this process, values are learned rather than discovered-and this applies mutadis mutandis to the valuation of the environment. More precisely, individuals will find themselves in such a milieu that they will try to assign values to nature from a wider perspective, taking into account other people's interests, their own ethical values, and their views on what is good for society as a whole, together with the results of ecological research. The Institutional approach further argues that "many of our environmental concerns are idealistic in nature, expressing our commitments, principles and values, so that the human response to the environment is misrepresented, when it is presented as lying entirely within the sphere of human preferences."26 It is within this context that Sagoff severely criticizes the contingent valuation technique on the ground that in such a method "private income is exchanged for personal benefit," thus encouraging people to approach the environment as individuals; or more specifically as private "consumers" rather than as "citizens. "27Once this ontological standpoint has been accepted, the Institutionalists tum their attention to the examination of the rise of environmental concerns. In that regard, Jacobs's question is self-revealing: "It seems evident that town planning has been radically transformed by the development of the car; but that in tum such planning has required most people to have a car. Might there be alternative patterns of economic development with different consumption behaviours and different levels of environmental degradation?"28 Jacobs's example suggests that different worldviews do indeed affect the ways in which social systems and their interactions with nature are understood. In their quest for an understanding of environmental behaviour, attitudes and values, members of the Institutional 118 Adaman and OzkaynaklEconomics-Environment school have considered power relationships and their impacts on the environment as a central, if not the principal, explanatory parameter. Power, broadly defined,· when applied to local and national levels is considered as a function of, first, individual socioeconomic characteristics (such as wealth, gender, and ethnicity), and secondly, the political framework in which these variables are mapped with respect to power.s? When the international dimension is considered, a nation's economic, political and military strength is obviously assumed to be the key factor in defining its relationship to power. Since the Institutional approach acknowledges interactive social processes that aim both at achieving social consensus on key environmental issues and at playing a role complementary to market institutions, it emphasizes the need for institutional structures that can facilitate such negotiations. Within this framework, ecological research is thought to have great importance in the areas of-to borrow Meyer and Helfman's categories-"detecting change, guiding and evaluating policy and management decisions, and designing sustainable systems. "30 The Institutional perspective recognizes, therefore, the need to provide information (supplied by various disciplines including economics, ecological sciences, sociology, law, political science, and psychology) in the context of an enlarged decision-making framework, where the aim is to guide and inform collective choices and to help resolve social conflicts. This flow of information should not be perceived as one-dimensional, since consensus among scientists-when it is attained-usually occurs only after informed discussion, experimentation, and debate. So, too, society in general influences the scientific community in setting its research agenda and choosing its methodologies.u The critical stance of the Institutionalists with respect to monetary reductionism applies mutadis mutandis to environmental issues. Kapp, the Institutional economist whose environmental interests we have noted, long ago argued forcefully on the impossibility of reducing environmental values to a single, one-dimensional criterion. He did so by jettisoning the assumption that social costs and benefits are heterogeneous and thus cannot be compared quantitatively among themselves and with each other (Kapp, 1970). In conjunction with 119 Studies in Political Economy Kapp's seminal remark, the term "incommensurability" has been proposed to denote the fact that it is simply not possible to reduce all relevant features of an object, service, or system to a single and common dimension. When applied to the environment, this observation implies the rejection of not just monetary, but also physical-such as energy-based valuationreductionism. But it has been suggested, rather, that "[w]e can rationally discuss sources of energy, transport systems, agricultural policies, patterns of industrialization, taking into account both monetary costs and socio-environmental (present and future) costs without an appeal to a common chrematistic unit of measurement."32 As a corollary, incommensurability is regarded as the epistemological foundation of a multicriteria decision too1.33The key premise here is that rather than solve conflicts, we need to shed light on their nature. Only in light of such knowledge can members of a particular society arrive at informed political decisions.s- The technique is conceived as an aid to decision-making on the part of those people who will have a say in the process. It might be useful to recapitulate what has been said thus far regarding the Institutional position in terms of the three dimensions set out in the Introduction. We first noted that the value of the environment and, in tum, that the extent and intensity of environmental degradation could only be defined at a societal level through a set of political discussions and negotiations. Secondly, the cause of this degradation was given as the failure to embed the economic system into the social system and the environment-a failure most likely caused by existing unequal power distributions within and between societies. Thirdly, the solution to environmental problems is to be formulated through a political process, its implementation requiring using a variety of economic and non-economic tools. Although the approach has elaborated suggestions regarding environmental issues, it does not fully consider the operation of the socioeconomic system as a whole. Readers, therefore, may find it difficult to see how decisions on environmental issues might be incorporated into the overall picture.v' More precisely, although the Institutional school acknowledges the presence of a network of social institu120 Adaman and OzkaynaklEconomics-Environment tions, some of which are value articulating, and consequently takes a critical view of monetary reductionism, it nevertheless relies-in the final analysis and with varying emphasison the operation of market forces to determine the changes in capacity that occur in economies. This outlook may be correct, and useful for understanding the dynamics of (today's) capitalist systems, but there is a widespread tendency to preserve this structure-that of a guided/regulated market-forces mechanism-for possible future (post-capitalist) prospects as wel1.36It is time, therefore, to consider the Marxist approach. It might be argued that, even though the original contributions of Marx and Engels do not adequately address the economics-environment relationship, the Marxist approach nevertheless provides a framework for questioning that relationship-as many Marxist contributors have recently undertaken. Interpreters of Marx and Engels appear to have achieved a consensus on the answer to the questions of how, and to what extent, nature was incorporated into the original Marxist vision. Their answer is that, despite the expressed concern for nature and environmental issues that appears here and there in their eeuvres, the founders of the Marxist school placed neither the environment, nor its degradation, at the core of their analysis. From that recognition, a step forward is not easy. While a few have argued that the Marxist agenda is unable to properly accommodate environmental issues, others have suggested that the Marxist agenda does in fact adequately take environmental issues into account, though perhaps not as explicitly as one would like.3?Still others have emphasized that the Marxist agenda is in need of modifications and revisions for nature to be properly addressed.v At any rate, a post-mortem is overdue. Nowadays, it is generally accepted that, although Marx and Engels' works show some sensitivity to ecological issues, a full consideration of the exploitation of nature is missing from their writings because, in the final analysis, the founders tended to abstract their discussions of social labour from both culture and nature.a? In the original Marxist vision, nature was ascribed no value apart from its instrumental value to human beings in allowing them to prosper and progress. Admiring greatly the forces of production and their domina121 Studies in Political Economy tion over nature, Marx and Engels, like most of their contemporaries, seem to have adopted a "Promethean," protechnological perspective, understanding human progress as corresponding to ever-greater human domination over nature. Moreover, the founders seem to have adopted, without much inquiry, the view that capitalist technology and economic development had to a large extent solved all problems of ecological limits and believed that the future (communist) society would live under conditions of abundance. The progressive historical role that was ascribed to capitalism in that regard meant a development of the productive forces "to the point where transition to a realm of freedom and abundance becomes a real historical possibility."4O Although the founders accepted that capitalist accumulation was subject to outer limits, they theorized these limits "as internally generated by the contradictory social-relational structures of capitalist economies, and mediated through class-struggles."41 In tum, they set the progressive forces' task as "to harness the technological possibilities of exploiting nature in the service of a fundamental change in the social relations of production in which the surplus labour value of the worker no longer accrued solely to the benefit of the capitalist class. "42 All in all, it would not be wrong to conclude that, despite some passing references to the importance of nature, Marx and Engels took mainly an anthropocentric position, disconnecting human beings from the rest of the ecosystem, and therefore considering the environment largely in terms of its direct impact on the well-being of humans.O The last point worth mentioning is the singling out, in orthodox Marxism, of members of the industrial working class as the main agents of change. The implication is that any social actor outside that class has no transformational role to play, however strong his or her desire to improve the environment. Although a textual reading gives little credit to the original Marxist vision in terms of incorporating nature into its analysis, an open question remains as to the extent Marxist methodology in general is compatible with an ecological perspective. It goes without saying that the core of the original Marxist writings was the analysis of capitalism. In that regard one may argue that some elements of the complaint that Marxist value theory downgrades-if it does not exclude122 Adaman and OzkaynaklEconomics-Environment the productive role of nature should be redirected to capitalism. Burkett, following this line, forcefully opposes any view that divorces Marxism from environmentalism, arguing that such a perspective fails to address systematically the "classrelational specificity of the natural conditions and limits of production in Marx's view."44Once such a link is established, Burkett will greet Marxist thought with the following prospect: "[T]he capitalism-nature relationship has a specific antagonistic character constituted by the wage-labour form of exploitation that underpins the value form of the commodity. Hence, the struggle for an ecologically rational production system must in large part be a struggle to overcome capitalist exploitation and the commodity form of the products of labour and nature. "45Although Burkett certainly has a point in arguing that the Marxist theorization of exploitation and commodification has explanatory power with regard to the economics-environment relationship, to jump from this assertion to the claim that Marx and Engels properly theorized the dependence of economic life upon the environment does not seem responsible. In that regard, Benton has attempted to modify Marxist theory so as to better understand the environmental dimension. His argument explicitly considers labour processes. What is required, he argues, is "the recognition that each form of social/economic life has its own specific mode and dynamic of interrelation with its own specific contextual conditions, resource materials, energy sources and naturally mediated unintended consequences (forms of 'waste,' 'pollution,' etc.)."46 This prospect constitutes the basis for two additional assertions. The first is that the ecological problems of any form of social and economic life have to be theorized as the outcome of this specific structure of natural/social articulation; the second is that each form of social and economic life is to be understood in terms of its own specific conditions and limits. This contextual approach is in no wayan argument for the "demolition" of social-relational issues; his intention is, rather, to suggest that "the patterning and dynamics of power relations and social conflicts in the labour process, and in the wider society, will be viewed very differently on the basis of a re-conceptualization of the labourprocess itself."47 At an operational level, Benton proposes 123 Studies in Political Economy the formation of a "typology of labour-processes" in which both the intentional structures (as such specific objects, mechanisms, substances, and the like can be identified as "instruments," "raw materials," "products" and so on) and the unintended consequences (that result from the combination of a particular intentional structure with its material embodiment) could be represented. Once such a framework is set up, different modes of production can be envisaged. Labour processes under socialism, on the one hand, could in theory be conceived as environmentally sensitive since it is possible to envisage these processes in line with the said relationship, but at the same time one should recall the Promethean element inherent in Marxism that may hamper the inclusion of environmental concern within socialism.ss In capitalism, on the other hand, Benton claims to find a tendency to "materially assimilate all labour processes to the productive-transformative model, and to drive productive practices themselves beyond their sustainable limits."49 This last point does not entirely support the claim that a capitalist mode of production can never be environmentally sustainable. Unlike those who stress the opposition between the forces of production and the natural conditions of production under capitalisms-e-in the sense that, as capitalism is conceptualized as invariably imposing a commitment to growth and expansion at any cost, the environment and the economy are understood as a zero-sum game-Benton suggests not a causality relationship but rather a tendency. In this looser conclusion, Benton's thought bears some resemblance to the post-modern version of Marxism where economic events---capital accumulation being the major one-are not reduced to the effects of class. Rather, in the post-modern version, the multifarious ways in which class and economic events simultaneously interact with one another are underIined.S Thus, the economy is not confined to the capitalist sector; on the contrary, it is seen as a complex totality of multiple class structures and non-class processes, including consumption and distribution, the corollary of which is that capital accumulation should no longer be seen as the sole determinant of capitalist dynamics. From this perspective, the environment is understood to be mediated by an environmental regime, as a result of which 124 Adaman and Ozkaynak/Economics-Environment ecological issues are formulated, constructed and injected into the discursive field. Thus, the environment is conceptualized not as an exogenous factor determining the social formation, but as constituted through political, cultural, and economic processes. Once both the environment and the economy are theorized as heterogeneous entities and endogenized with respect to each other and the rest of society, their interaction can no longer be formulated as a zero-sum game. It becomes possible, even, to imagine a "Green Capitalism" in which "environmentally friendly commodities" are differentiated from otherwise identical commodities because of the existence of the socio-cultural mediation of a particular environmental regime.x Although the debate over the compatibility of Marxism and environmentalism is far from over, the explanation provided by the Marxist approach for the distribution of pollution among individuals and societies appears fairly robust: it arrives at the historically persistent charge that these damage costs become "class costs" because of their uneven social incidence-workers who are subject to oppression and exploitation both at home and at work are exposed to more than their fair share of pollution. The view through Marxist lenses of the international arena also reveals the exploitation process manifesting itself in the operations of transnational corporations. Furthermore, Marxists see from afar structural linkages between economic development in the North and the South, links that radically affect the environment in the South. In passing, the environmental justice movement against the disproportionate exposures suffered by racial minorities and the poor, particularly in the context of mining and the dumping of toxic waste (e.g., in the United States and South Africa) should be acknowledged.P The Marxist explanation of such linkages and of the uneven share of the degradation borne by the Southern sphere is based on the so-called "international re-division of labor."54 Amin's protest is to the point: "Why should people, who by their negligible consumption, only have minor responsibility for the disaster, accept an order which only allows the perpetuation of monstrous waste by the rich minority of the planet?"55 All in all, the Marxist approach takes a "reproductive" approach to the economy, and ipso facto supports a replace125 Studies in Political Economy ment of market calculus (and private ownership) with planned production for social need (and common ownership). In that regard, it is worth referring to the Sraffian framework viz. a system of production of commodities by means of commodities, which analyses the formation of production prices from the supply side, with the well-known result that the costs of producing different commodities and the distribution of income are interdependent. The Sraffian framework can in fact be extended to deal with renewable and non-renewable natural resources.e To review what has been said so far about the Marxist position in terms of the three dimensions set out: from the first one-the definition of environmental degradation-we have observed that the Marxist school, either in its original version or its revisions, does not appear explicitly to consider this aspect. When attention is given to the cause of this degradation-the second dimension-we have noted that the concept of "unintended consequences of the production processes" does provide-within the Marxist approach-a satisfactory explanation; it has further been emphasized that the Marxists seem to agree that the consequences of a capitalist production process are likely to be detrimental to nature. Finally, we have acknowledged that these adverse consequences-the third dimension-can adequately be addressed only after production processes have been restructured. A Comparative Evaluation and Looking Forward Having sketched the interconnectedness of economics and the environment through glimpses of three contemporary schools of economic thought, we now embark upon a comparative evaluation of the three contenders. The Neoclassical approach, as we have seen, amounts to a cost-benefit analysis based on costs and benefits derived from the exogenously determined and ethically unchallengeable preferences of separate and autonomous individuals whose decisions collectively have an impact on the environment. This framework is consonant with the suggestion made in 1992 by Lawrence Summers, as the chief economist of the World Bank, that the migration of dirty industries to less developed countries should be encouraged, for the following reasons: 126 Adaman and OzkaynaklEconomics-Environment 1. As "[t]he measurement of the costs of health-impairing pollution depends on the forgone earnings from increased morbidity and mortality," a given amount of health-impairing pollution should be done in the country with the lowest wages; 2. As "[t]he costs of pollution are likely to be non-linear as the initial increments of pollution probably have very low costs," vastly under-polluted African countries should be receiving pollution, and 3. As "[t]he demand for a clean environment for aesthetic and health reasons is likely to have very high income-elasticity," a welfare improvement necessitates once again the migration of pollution away from rich countries.v These words, shocking to the tender humanist conscience, set forth just one of the inescapable implications of the theory, for Mr. Summers here considers only exogenously given desires and wants, and does not incorporate needs (of, say, citizens of "under-polluted African countries") into his analysis. Moreover, in assuming the reductionist perspective of expressing all alternative actions via a common criterion viz. money, the theory foresees no problem in accepting the substitutability of human-made capital for nature. The Institutional perspective clearly rejects any individualist and consequentialist reductionism of utility-maximizing behaviour. Because the market mechanism is seen as inextricably entwined with other social institutions, the Institutional approach is said to underscore the importance of non-market deliberative interactions in forming public policies with respect to environmental issues. Moreover, the Institutional position has been critical of the idea of substituting humanmade capital for environmental goods and services. All in all, the Institutional argument amounts to an embedding of the economic system in the environment, rather than a consideration of the two as separate systems. To make this integration or embedding possible, the approach rejects an individualist methodology and argues instead for deliberative mechanisms. Nonetheless, as the authors of this paper have argued, the Institutional school relies, in the final analysis, on a modified market mechanism not only to explain contemporary social formations but also in its proposed models for the future. 127 Studies in Political Economy The third approach, the Marxist, greatly enlarges the arena for investigating the compatibility of the market and the social-deliberative mechanisms. At a more general level, the Marxist approach certainly appears to have a point when the Institutional approach claims that if market forces were to play a role on the specific issue of investment and disinvestment, then the entire idea of deliberative design would be endangered. Since the impacts of (dis )investments on the environment are obvious-to the extent that decisions are taken by atomistic units-both the Neoclassical and the Institutional approaches will be subject to Marxist critiques. Yet Marxist scholars who focus primarily on the capitalist mode of production have thus far not considered in full the subject of environmental issues in a post-capitalist society. We hope the above discussion has made clear the following points: first, that Neoclassical reductionism and individualism are unlikely to lead us to an environmentally attuned economy; secondly, that Institutionalists' emphasis on deliberative and participatory mechanisms is crucial to us as we envision the multidimensionality of the economics-environment relationship, even though the line they draw between issues with and issues without environmental impact is naive, and thirdly, that although the Marxist school rightly criticizes the anarchy of production, with its adverse impacts on nature, it fails to provide a viable alternative organizational structure that will embed the economy in the environment. What is required, therefore, is an alternative vision that will combine deliberative mechanisms with planning at a general level. Planning is vital if the economy is to be embedded in society and nature; and, among a variety of proposals, the one called "Participatory Planning" seems to offer the most workable project for the future. Furthermore, as the rental values of society's fixed assets as well as its natural resources also need to be determined, this process itself should include participatory mechanisms as well. Participatory Planning is an umbrella concept, one that incorporates, with different melanges, participation and planning in a prospectus for an alternative societal organization. Although participatory forms of economic organizations have had a long history, the modelling of an economy based on Participatory Planning is 128 Adaman and OzkaynaklEconomics-Envil'onment rather new.58Its aim is to confront head-on the dilemma that Nove once described so neatly: "There are horizontal links (market), there are vertical links (hierarchy). What other dimension is there?"59 The goal, therefore, seems to be to plan and co-ordinate economic life without subjecting people to the "coercive power of either administrative directives from the hierarchically organized planning system or market forces operating with inherently unpredictable and unintended consequences."60 Furthermore, should the valuation problem be conducted through participatory processes, the "rental for the use of each natural resource would reflect the socially determined evaluation of its relative scarcity with respect to potential current use and, in the case of exhaustible resources, of its desired rate of deletion. "61 Two prerequisites can be cited before a process of Participatory Planning begins: first, people must have access to the material and personal resources necessary for their participation, if the social process of discovery is to be effective; secondly, decision-making at all levels needs to be conducted through a participatory process involving all those affected by the decision. Once the right to decide on the use of social and economic assets is vested in those who are affected by the decisions, then planning will provide "a structure, a procedure, a form of social organization, that enables people to make most effective use of the possibilities open to them to achieve their objectives. "62 The Devine model, more precisely, sees the basis of economic organization as a process of "negotiated coordination" among those affected by the decisions involved. Within this principle, a distinction between "market exchange" and "market forces" is made-the former involving transactions that consist of goods produced within existing capacities, between buyers and sellers, and the latter referring to the process whereby changes are brought about in the underlying allocation of resources, the relative size of different sectors, and the geographical distribution of economic activity.63 Devine's model incorporates market exchange but not market forces; hence, while market exchange coordinates the use of existing capacity, changes in the structure of productive capacity are negotiated and coordinated in the ex ante sense by those affected by them. As such, and with openness of 129 Studies in Political Economy information being assumed to play a central role in the model, it is claimed that the values and interests of people will interact and shape one another in such a way that interdependencies in economic decisions can be explicitly considered and dealt with, long- and medium-term planning of key economic parameters be set, mistakes be openly and publicly discussed, and lessons drawn. When the economics-environment relationship is questioned, this perspective provides a framework to enable people to shape their environment, within the possibilities open to them, on the basis of priorities that will be openly and publicly debated and negotiated. More specifically, "[S]uch a system would politicize the economic sphere, introducing into the process of co-ordinating economic activity the specific interests of those affected and the wider consequences anticipated for the environment...The potential of this way of co-ordinating economic activity is perhaps most evident when thinking about the reshaping of production, consumption and life styles that is likely to result from the combined imperatives of global redistribution and ecological sustainability."64 Were this framework adopted, societies would be able to debate decisions on environmental issues from a wider perspective including social, ethical and political factors as well as economic ones. There is, of course, a clear contrast between the Neoclassical approach, which regards the valuation issue as the use of "neutral" tools that will make individuals reveal the "true" value they place on the environment (in monetary terms), and the Participatory Planning approach which welcomes planning of the use of nature through participatory and negotiated networks-a process logically separate from the aggregation of individual benefits and costs. As such, not only would people gain understanding of their own and others' interests and values, but they would also have the opportunity to influence other people's approaches. This perspective will also be conducive to the creation of a milieu where people's needs will be fully considered and the intrinsic values of non-human beings receive serious consideration. With this approach, the social system can be reorganized in such a way as to make production decisions on the basis of needs defined prior to production, rather than needs based solely on production decisions. 130 Adaman and OZkaynaklEconomic:s-Environment Moreover, much needs yet to be done. The Participatory Planning mechanism does not provide, at this time, a completed model that explains how specific decisions with environmental impacts are to be made. On the other hand, although recent studies conducted under the rubric "ecological economics" provide detailed proposals regarding environmental issues, they do not as yet fully explore the issue of how to frame economic life in general-s-creating the illusion that a demarcation line between the environment and nonenvironment exists and can be easily drawn. We hope that the methodological approach we have proposed will open wide green avenues in the policymaking areas of environmental issues.

Overgrazing is a typical example of the overuse of natural resources, leaving future generations with far less grazing areas. An upstream industry discharging harmful wastes into a river, harming the fish stock of the river, which then affects the earnings of downstream fishermen, is a typical example of pollution. 5. More specifically, one can either change the prices of existing market activities by taxing environmental damage or by subsidizing environmental improvement, or one can create markets for environmental goods by issuing tradeable pollution permits. Furthermore, it is assumed that, in discussing pollution, the efficiency required is regained by bringing economic activity down by either producing or consuming less; this will of course be the only case when the abatement option is not available or is not economically feasible. 6. It is worth mentioning that in cases where governments are not immune to failures, the relative size of polluters and victims might be an additional dimension here (as pinpointed long ago by M.

The use value derives from the actual and direct use of the environment; the altruistic value is the value individuals place on other people having a clean and unexploited environment; the bequest value is the value that the current generation places on the availability to future generations of a clean and unexploited environment; and the existence value is the value attached to the knowledge that the species exists and will continue to exist, independent of any use.

Martinez-Alier, "Political Ecology, Distributional Conflicts, and Economic Incommensurability," New Left Review 211 (1995), pp. 70-88). As a consequence, the way these rental values are to be determined assumes great importance.
