intergenerational equity and sustainability abstract this paper explores the limitations of conventional economic analysis of intergenerational problems and examines some of the alternatives suggested in the literature it is argued that proper consideration of future generations has at least three requirements first when future costs and benefits are considered it should be taken into account that they are to be enjoyed by different generations second the sustainability requirement should be adopted this represents an equity commitment to the future and implies the recognition that future generations have the right to nondeteriorated ecological and economic capacity the paper studies the ways in which the recognition of these rights might be incorporated into economic evaluation and management third an appropriate institutional network to enforce the recognition of these rights in decision making processes should be constituted its design and necessary functions are also analyzed

an analysis of policy initiatives to promote strategic research partnerships strategic research partnerships srps have become a salient feature of the us national innovation system we provide an overview of srps and examine the antecedents and consequences of centerpiece legislation designed to stimulate the formation of srps the national cooperative research act ncra of 1984 ncra allows firms to disclose their research joint ventures rjvs to the department of justice which enabled them to significantly reduce their exposure to antitrust litigation we estimate an econometric model of trends in rjv filings and find that as intended by the legislation the propensity of firms to engage in rjvs is sensitive to changes in the global competitiveness of us high technology industries more importantly our results suggest that the establishment of the commerce department s advanced technology program which provides financial support to firms that engage in collaborative research projects induced firms to engage in additional privately financed rjvs this is a spillover mechanism that warrants further attention as national innovation systems evolve

reforming residential electricity tariff in china block tariffs pricing approach the chinese households that make up approximately a quarter of world households are facing a residential power tariff reform in which a rising block tariff structure will be implemented and this tariff mechanism is widely used around the world the basic principle of the structure is to assign a higher price for higher income consumers with low price elasticity of power demand to capture the non linear effects of price and income on elasticities we set up a translog demand model the empirical findings indicate that the higher income consumers are less sensitive than those with lower income to price changes we further put forward three proposals of chinese residential electricity tariffs compared to a flat tariff the reasonable block tariff structure generates more efficient allocation of cross subsidies better incentives for raising the efficiency of electricity usage and reducing emissions from power generation which also supports the living standards of low income households

optimal acid rain abatement policy for europe an analysis for the year 2000 acid rain causes greater environment damage than would occur if countries act cooperatively based on new estimates of sulphur abatement cost functions the potential gains from cooperation are calculated for europe various cooperative abatement rates are compared with the rates implied by recent international agreements the 30 club and the second sulphur protocol it is shown that the monetary gains from cooperation may be smaller than previously thought the distinction is made between primary and secondary abatement and their respective roles are discussed it is shown that agreed targets can only be met if primary measures eg fuel switching are adopted

the impact of ec environmental policy on british coal the courts and legal services act 1990 legalized a form of contingent contract between lawyers and clients in england and wales however it maintained the historic ban on american style contracts where lawyers receive a percentage of winnings in a successful case but nothing in the event of case loss the paper looks at the economic rationale for such american style contingent fees it then analyses the arguments used for and against them in britain in the 1989 90 pre legislation debate this is done with reference to the theoretical and empirical economic literature such fees have generated the arguments discussed concern access to justice the possibility of excessive contingent fees client lawyer conflicts of interest and the quantity of litigation under the fees the conclusion reached is that the british government s position on american style fees is acceptable except on the issue of excessive fees and that it should continue to consider introducing contingent fees copyright 1993 by oxford university press

germany s solar cell promotion dark clouds on the horizon abstract this article demonstrates that the large feed in tariffs currently guaranteed for solar electricity in germany constitute a subsidization regime that threatens to reach a level comparable to that of german hard coal production a notoriously outstanding example of misguided political intervention yet as a consequence of the coexistence of the german renewable energy sources act eeg and the eu emissions trading scheme ets the increased use of renewable energy technologies does not imply any additional emission reductions beyond those already achieved by ets alone similarly disappointing is the net employment balance which is likely to be negative if one takes into account the opportunity cost of this form of solar photovoltaic pv support along the lines of the international energy agency iea 2007 energy policies of iea countries germany 2007 review international energy agency oecd paris p 77 we recommend the immediate and drastic reduction of the magnitude of the feed in tariffs granted for solar based electricity ultimately producing electricity on this basis is among the most expensive greenhouse gas abatement options

a framework for scaling and framing policy problems in sustainability abstract it is argued that a necessary but lacking component of our approach in seeking policy responses to sustainability issues is some repeatable means whereby the relative magnitude and characteristics of these various policy problems faced in a given context can be analysed and described to this end a simple and tentative framework is constructed based on the definition of the key attributes which shape policy problems pertaining to environmental change these are spatial scale of cause and effect magnitude timing and longevity of possible impacts reversibility mensurability complexity and connectivity nature of cause s relevance to the given polity tractability availability and acceptability of means public concern and existence of goals these attributes inform a general taxonomy of micro meso and macro problems the attributes and the taxonomy are described with supporting examples to illustrate possible application of the framework it is discussed briefly in the contexts of operationalising the precautionary principle and policy instrument choice it is concluded that the framework can help focus debate and operationalise vague principles introduce relativity into the notion of sustainability and make policy choice more efficient

the rise and fall of german hard coal subsidies abstract beginning with the coal crisis of 1958 the survival of the german hard coal mining sector has been heavily dependent on subsidies for several decades these subsidies are a complex system of almost 60 different measures often with conflicting objectives annual financial support for this subsidy system grew from 0 6 billion in 1958 to 7 5 billion in 1989 with the majority of the funding financed outside the public budget by a special fund based on the coal penny kohlepfennig in 1995 the abolishment of the coal penny in connection with budget constraints led to a significant subsidy decrease to 3 5 billion a recent agreement between the federal government and the mining state of north rhine westphalia in 2003 however seems to have fixed german hard coal subsidies at the 2 billion level for the time after 2012

technological joint venture formation under the real options approach abstract technological joint ventures as powerful mechanisms to attain innovation have become commonplace firms form tjvs in an effort to access future technological opportunities without losing flexibility in uncertain contexts the real options approach allows the essence of such managerial thinking to be captured although research in this line remains scarce drawing on the real options approach and using an eight year panel of 4050 spanish manufacturing firms we examine under which conditions firms form technological joint ventures we find that a firm s propensity to form technological joint ventures is positively related to its absorptive capacity and to the degree of environmental technological uncertainty and negatively related to the risk of pre emption by rivals and the existence of opportunity costs our study contributes to bridging the gap between finance theory and strategic analysis in addition it shows practitioners the applicability of the real options approach for decision making results suggest that public policies should particularly although not exclusively foster participation of young and small firms in technological joint ventures we also suggest using managerial perceptions as a guide for channeling public grants

scale prices and biophysical assessments abstract in a recent forum on biophysical assessments a number of ecological economists expressed serious reservations about the use of prices to assess the appropriate scale of macroeconomic systems while such reservations are warranted the preference for biophysical assessments over prices indicates that many ecological economists are focussing on one notion of scale and neglecting another altogether there are two notions of scale that are critical to achieving sustainable development sd one is the maximum sustainable macroeconomic scale the other is the optimal macroeconomic scale the maximum sustainable scale is the largest macroeconomic scale that can be sustained by a throughput of matter energy that is within the ecosphere s regenerative and waste assimilative capacities the optimal scale is a preferable macroeconomic scale and is one that is not only sustainable but one that maximises the net benefits of economic activity biophysical assessments are needed to determine the maximum sustainable scale because ecological sustainability is a biophysical problem not an economic problem thus it is through biophysical assessments that the necessary restrictions on the incoming resource flow can be calculated and imposed however since the achievement of an optimal macroeconomic scale is an economic problem albeit a constrained economic problem relative prices are required to efficiently allocate the sustainable resource flow so the macroeconomy can adjust to the optimum failure to recognise the two notions of scale and the most appropriate means of their assessment is likely to thwart rather than advance the movement toward sd

valuation and management of wetland ecosystems we recently completed a study of wetland values in coastal louisiana that employed both willingness to pay and energy analysis based methodologies and were able to bracket a range of values within which we feel fairly confident the true value lies however a large amount of uncertainty remains our current estimates of the total prsent value of an average acre of natural wetlands in louisiana are us 2429 6400 per acre assuming an 8 discount rate to 8977 17000 per acre assuming a 3 discount rate at the lowest value the current annual rate of loss of louisiana wetlands 50 sq miles per year is worth about 77 million at the largest value it is worth about 544 million in this paper we a discuss the fundamental theoretical and practical problems underlying natural resources valuation b summarize our methods and findings for louisiana wetlands and c elaborate on some of the more recalcitrant problems attending applied natural resource valuation including discounting and dealing with uncertainty and imprecision the discount rate makes more difference in the final result than any other one factor and yet there is much disagreement about the appropriate approach to discounting natural resources we discuss the discounting problem as applied to natural resources and argue for lower discount rates for valuing renewable natural resources than apply for other aspects of the economy it now seems clear that no reasonable amount of effort will produce very precise estimates of wetland values and we suspect this is also the case for several other classes of natural resources we elaborate a wetlands asurance bonding system to address these problems

the role of policy instruments in the innovation and diffusion of environmentally friendlier technologies popular claims versus case study experiences abstract moving towards sustainability will require that new environmentally friendlier technologies are developed and widely adopted policy instruments that promote eco efficiency are therefore necessary some claims frequently made in the literature on the relationship between policy instruments and technological development are examined the claims concern regulations environmental taxation and funding of research and development the claims are explored on the basis of empirical evidence from two sectors the pulp and paper industry and the marine engine industry little support was found for some of the claims in some cases even contradictory findings and for some claims the findings differed between the sectors and even within a sector depending on the issue

an optimal path to extinction poverty and resource degradation in the open agrarian economy this paper constructs a model of the open agrarian economy in order to explore the tendency of many such economies to evolve along paths characterised by severe environmental degradation it pays special attention to the importance of commodity prices and the transfer system in determining agricultural activity levels in ecologically delicate systems

fossil fuel subsidy reforms and their impacts on firms abstract while the potential adverse effects of fossil fuel subsidy reform are well documented for households the literature has largely ignored the effect of subsidy reform on firms competitiveness this paper discusses how firms are affected by and respond to energy price increases caused by subsidy reforms it highlights that cost increases both direct and indirect do not necessarily reflect competitiveness losses since firms have various ways to mitigate and pass on price shocks this paper presents and discusses direct and indirect transmission channels for price shocks and firms response measures absorbing cost shocks into profits inter fuel substitution increasing energy and material efficiency and passing on price increases it argues that further micro econometric studies using enterprise surveys are essential for quantifying the role of these mechanisms and for designing policy measures that ensure that competitiveness losses due to subsidy reforms are minimised

estimates of energy subsidies in china and impact of energy subsidy reform abstract for a transitional economy such as china some energy subsidies are reasonable and sometimes even necessary for achieving social goals however with rising energy prices and environmental concerns we see conflicts emerging between energy subsidies energy demand supply fundamentals and climate change considerations energy subsidies have important implications for sustainable development through their effects on energy use efficiency and the choice of fuel source this paper applies the price gap approach to estimate china s energy subsidies results indicate that china s energy subsidies amounted to cny 356 73 billion in 2007 equivalent to 1 43 of gdp subsidies for oil products consumption are the largest followed by subsidies for the electricity and coal sectors furthermore a cge model is used to analyze the economic impacts of energy subsidy reforms our findings show that removing energy subsidies will result in a significant fall in energy demand and emissions but will have negative impacts on macroeconomic variables we conclude that offsetting policies could be adopted such that certain shares of these subsidies are reallocated to support other sustainable development measures which could lead to reducing energy intensity and favoring the environment

universities and fundamental research reflections on the growth of university industry partnerships the recent rise in university industry partnerships has stimulated an important public policy debate regarding how these relationships affect fundamental research in this paper we examine the antecedents and consequences of policies to promote university industry alliances although the preliminary evidence appears to suggest that these partnerships have not had a deleterious effect on the quantity and quality of basic research some legitimate concerns have been raised about these activities that require additional analysis we conclude that additional research is needed to provide a more accurate assessment of the optimal level of commercialisation

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

when will fossil fuel reserves be diminished crude oil coal and gas are the main resources for world energy supply the size of fossil fuel reserves and the dilemma that when non renewable energy will be diminished is a fundamental and doubtful question that needs to be answered this paper presents a new formula for calculating when fossil fuel reserves are likely to be depleted and develops an econometrics model to demonstrate the relationship between fossil fuel reserves and some main variables the new formula is modified from the klass model and thus assumes a continuous compound rate and computes fossil fuel reserve depletion times for oil coal and gas of approximately 35 107 and 37 years respectively this means that coal reserves are available up to 2112 and will be the only fossil fuel remaining after 2042 in the econometrics model the main exogenous variables affecting oil coal and gas reserve trends are their consumption and respective prices between 1980 and 2006 the models for oil and gas reserves unexpectedly show a positive and significant relationship with consumption while presenting a negative and significant relationship with price the econometrics model for coal reserves however expectedly illustrates a negative and significant relationship with consumption and a positive and significant relationship with price consequently huge reserves of coal and low level coal prices in comparison to oil and gas make coal one of the main energy substitutions for oil and gas in the future under the assumption of coal as a clean energy source

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

evaluating environmental programs the perspective of modern evaluation research large scale environmental programs generally commit substantial societal resources making the evaluation of their actual effects on the relevant outcomes imperative as the example of the subsidization of energy saving appliances illustrates much of the applied environmental economics literature has yet to confront the problem of proper attribution of effects to underlying causes on a convincing methodological basis this paper argues that recent results in the econometrics and statistics literature on program evaluation could be utilized to advance considerably in this context in particular the construction of a credible counterfactual situation is at the heart of the formal statistical evaluation problem even when controlled experiments are not a viable option appropriate approaches might succeed where traditional empirical strategies fail to uncover the effects of environmental interventions

major oil exporters may profit rather than lose in a carbon constrained world the organization of petroleum exporting countries opec claims compensation for losses in expected oil export revenues due to co2 mitigation measures in developing countries these losses are expected for two primary reasons a reduction in the consumption of oil in importing countries and a reduction in the producer price of oil taxation in an importing country implies a transfer of rents from producers to consumers so far most studies have focused on these two mechanisms and corroborated that revenue losses for opec are to be expected however there are also mechanisms that may be expected to raise the price of oil products in a cost effective regime for dealing with climate change i e a regime in which all or most countries participate and in which the same carbon price is applied on all carbon emitting activities the cost of using unconventional oil or synthetic diesel from coal will increase even more than the cost of using conventional oil given that reserves of conventional oil are expected to dwindle over time heavy oils and coal to liquids might set the long run price for liquid fuels which means that the price of oil would increase beyond the carbon fee i e the rent on conventional oil would increase we use an energy economic optimization model to analyze these three mechanisms we find that the net present value of opec revenue from conventional oil increases slightly at most by 4 percent with a global co2 restriction regime we also consider conditions under which this result does not hold

an evaluation of the impact of reducing energy subsidies on living expenses of households abstract a policy of subsidizing energy has been pursued in the islamic republic of iran to help the poor and to utilize the relative advantages of the country but it has been realized that energy subsidy has led to market distortion and welfare loss hence elimination of energy subsidy is considered as a crucial matter changes in energy policy are hindered by the uncertainty on the impact of reducing energy subsidy on the living expenses of population in the present article the distribution of resources through energy subsidy is evaluated and the direct and indirect effect of eliminating energy subsidies on the living expenses is estimated with the help of an analytical tool that has been developed it is then concluded that additional financial resources obtained from reduction of energy subsidies could be allocated for compensating the decrease in purchasing power of households the results of analysis reveal that more egalitarian distribution of resources and helping the poor could be achieved through implementation of a progressive policy of social security that is supported by financial resources available from elimination of energy subsidies

environmental bonds and environmental research in innovative activities abstract this paper considers the incentive to uncover potential future social costs of activities having no historical precedents since ex ante markets in the future external effects of historically unique activities are non existent the private incentives to uncover the possibility of thalidomide type results in such activities is weak the paper discusses the value of sequentially determined environmental bonds as mechanisms for the generation of research funds in these cases and derives measures for the calculation of such bonds

environmental policy based on strict liability implications of uncertainty and bankruptcy a firm level model is developed to analyze the impacts of bankruptcy and uncertain firm wealth on incentives for safety under a strict liability rule future damages and wealth are uncertain and a firm s income earning activities that possibly create damages are incorporated into the model this analysis shows that firms do not always undertake more of a risky activity than is socially desirable for the extremely hazardous industry case larger firms always undertake less of a risky activity than smaller firms for the cyclical industry case larger firms do not always conduct less of a risky activity than smaller firms

ecological economics and scientific controversies lessons from some recent policy making in the eec abstract contrasting the very limited scientific evidence on the forest dieback issue with the sudden adoption of policies on air pollution decided in the frg 1983 1984 and extended to the european community 1985 we propose an interpretative framework for the real internalization process at work in what was tantamount to a social crisis for public opinion the media and political actors we conclude that open scientific controversies on some environmental issues effects causes solutions pave the way for some actors to use the issue for their own techno industrial strategies quite alien to ecological constraints in cases of very high uncertainties on impacts it becomes impossible to apply conventional social cost benefit analysis scba as an optimizing tool we propose to develop economic analysis as a negotiation language and to give pride of place to the value of learning time and to the crucial role of technological pluralism as a condition for flexibility in the future

externality or sustainability economics abstract in an effort to develop sustainability economics baumgartner and quaas 2010 neglect the central concept of environmental economics environmental externality this note proposes a possible connection between the concepts of environmental externality and sustainability in addition attention is asked for other aspects of sustainability economics namely the distinction weak strong sustainability spatial sustainability and sustainable trade distinctive sustainability policy and the ideas of early sustainability economists i argue that both sustainability and externalities reflect a systems perspective and propose that effective sustainability solutions require that more attention is given to system feedbacks notably other regarding preferences and social interactions and energy and environmental rebound the case of climate change and policy is used to illustrate particular statements as a conclusion a list of 20 insights and suggestions for research is offered

optimal abatement of sulphur emissions in europe this study presents a mathematical model for determining cost effective emissions control strategies in europe by minimizing sulphur abatement costs subject to different pollution control targets the purpose is to compare the efficiency of a uniform percentage emissions reduction with a scenario that takes variation in environmental conditions into account underlying the proposed model is the belief that a full cost benefit analysis of acid rain abatement is infeasible the model focuses on the costs of abatement and provides an estimation of the gains or losses that countries could achieve if they co operate in their policies rather than act independently

analysis of the changes in the scale of natural gas subsidy in china and its decomposition factors abstract this paper applied the price gap approach to estimate natural gas subsidy in china during 2007 2015 and employed the lmdi method to analyze the influencing factors of the changes in the subsidy scale the results showed that the chinese government raised the domestic gas price in contrast to the slump in global gas price in 2009 which accelerated the huge decrease in the natural gas subsidy scale but the stagnation in price adjustment immediately led to a rebound in natural gas subsidy during 2010 2012 however the level of natural gas subsidy has declined substantially in the industrial and commercial sectors since the natural gas pricing mechanism reform began in 2013 but the level of residential natural gas subsidy still remained high because the city gate pricing mechanism was not extended to this sector the pricing mechanism was the most important decomposition factor of changes in the level of natural gas subsidy the contribution rates of competitive gas price pricing mechanism consumption structure and natural gas consumption on decrease in natural gas subsidy scale were 11 08 101 21 3 15 and 9 14 respectively during 2013 2015 a reasonable and well implemented pricing mechanism can prevent a rebound in natural gas subsidy therefore the government should seize the current opportunity of sufficient natural gas supply and relatively low gas price to deepen and advance the natural gas pricing mechanism reform

guilty until proven innocent regulation with costly and limited enforcement abstract we consider optimal regulations for a polluting firm when regulators cannot observe emission control costs and can only observe emissions via costly monitoring fines or subsidies for enforcing compliance are also limited the optimal regulations resemble a deposit refund system the firm reports its emissions and pays an initial tax based on this report if the firm is monitored it receives a rebate when actual and reported emissions coincide the enforcement constraints and the firm s rights determine whether the incentives to reduce emissions are optimally provided by varying the rebate for compliance the monitoring probability or the initial tax

what will happen to the producer prices for fossil fuels if kyoto is implemented implementation of the kyoto commitments will result in lesser global fossil fuel consumption in 2010 than would occur in the absence of climate policy the paper explores how the consumption change resulting from climate policy implementation could affect the producer prices of fossil fuels the conclusion is that the price impact will be insignificant if the climate policy goals are established credibly and in the near future for that will give rationally behaving fossil fuel producers ample time to adjust production capacity to the changed outlook for future demand it is argued that as long as capacity develops in line with demand prices should remain the same irrespective of the speed and direction of demand change

bargaining and international policy cooperation the past decade has witnessed the growth of a large literature on international cooperation in trade and macroeconomic stabilization policy virtually all the models developed to date however are based on one of two extreme assumptions concerning governments ability to commit to international agreements either they assume that governments can make constitutionally binding long term agreements or else they assume that governments have no ability to make legal commitments whatsoever in the latter case international policy cooperation is possible only to the extent that reputational factors will allow in this paper i consider a world in which there is no legal mechanism for enforcing long term international agreements but where governments must still incur some small direct costs if they renege these small costs might arise due to legislative or administrative frictions i also allow for the possibility that international economic policy agreements can include small sidepayments for example in negotiating a bilateral reduction in tariffs two allies could simultaneously agree to redistribute the burdens of defense expenditures

reducing subsidies on household fuels in india how will it affect the poor kerosene and lpg are widely used in households in india for lighting and cooking these fuels have historically been subsidized as part of the restructuring of the energy sector the government is committed to limiting these subsidies this paper examines the impact of reducing energy subsidies on the welfare of the poor the paper uses data from nationally representative surveys of over 100 000 households the paper concludes that the case for reducing lpg subsidies is strong although the kerosene subsidy is an inefficient means of subsidizing fuel use by the poor reduction in it will need to be supported by other policies that would limit the adverse impacts

policy cooperation among benevolent governments may be undesirable this paper presents a simple counterexample to the belief that policy cooperation among benevolent governments is desirable it also explains circumstances under which such counterexamples are possible and relates them to the literature on time inconsistency since the work of hamada 1976 investigating the effects of increasing policy cooperation among countries has been a major topic in international economics a standard conclusion of this work is that increasing policy cooperation among countries is desirable in a seminal paper rogoff 1985 has challenged this view using a simple monetary model rogoff shows that cooperation among policy makers can lead to a lower level of welfare than noncooperation does rogoff s result has caused much consternation among those who advocate policy cooperation and his work has been criticized along several dimensions for example some authors including canzoneri and henderson 1988 have noted that a key assumption in rogoff s model is that the objective function of each country s policy maker does not coincide with the objective function of its residents indeed if in his model policy makers maximize the welfare of their country s residents the counterexample is overturned and cooperation strictly dominates noncooperation this feature leads some to interpret rogoff s result as simply saying that if policy makers form a coalition against the private sector they may be worse off than if they do not others such as neck and dockner 1988 have claimed that rogoff s result depends on private agents acting strategically under this interpretation rogoff s result is relevant to say economies with a large trade union but not to economies with a large number of competitive private agents in a somewhat different vein persson 1988 and especially devereux 1986a b have questioned the significance of welfare comparisons across different institutional regimes in a model without a solid foundation for the behavioural relationships this paper presents a simple model in which governments are benevolent but cooperation is still undesirable the model is a two country version of fischer s 1980 optimal tax model in it private agents are competitive in that each agent takes both prices and government policies as uninfluenced by his actions and each government maximizes the welfare of its country s residents in the paper the two different regimes cooperative and noncooperative

an experimental analysis of the effectiveness of an environmental assurance bonding system on player behavior in a simulated firm it has long been recognized that the present command and control methods for pollution abatement are inefficient using market mechanisms for environmental management is a promising alternative to the direct regulatory approach market mechanisms are just beginning to appear in u s environmental policy for example tradable permit schemes are being developed and implemented for some air pollutants under the amended clean air act various other forms of taxes and tradable permits have been proposed however these systems do not address the large uncertainty inherent in most environmental problems one mechanism currently being studied to address uncertainty more effectively is a flexible environmental assurance bonding system designed to incorporate environmental criteria and uncertainty into market incentives this study uses an experimental approach employing an interactive computer game simulation model with human players to examine the effectiveness of the assurance bonding system under varying degrees of uncertainty an environmental cost efficiency index ecei or profit per unit waste is used to measure player performance preliminary results indicate that players are more successful under the assurance bonding system in terms of ecei than under the simulated current system

government failure the cause of global environmental mismanagement abstract this paper argues that although pollution may move across national boundaries and polluters are mobile governments should be able to coordinate a sound management of the environment through transfer payments or commitments however governments may respond to political pressure rather than maximize social welfare because pollution tends to hurt large unorganized groups future generations and those who are uninformed there is likely to be a government failure resulting in too little protection of the environment government failure in one country may also reduce the desirable level of cleaning in other countries brief analyses of atmospheric emissions the destruction of the tropical rainforest consumption of tobacco and the development and diffusion of new technology by multinational corporations further suggest that government failure is a major cause of environmental mismanagement it is advocated that an international body should be instituted to compensate for this

household heterogeneity impact of removing energy subsidies in china direct and indirect effect abstract reforming subsidies for fossil fuels is a challenging prospect for many governments the impact of such a reform on households is a major concern for the government this paper investigates the heterogeneous impacts of eliminating energy subsidies on households in china from direct and indirect perspectives the results of the direct effects show that the removal of energy subsidies particularly for removing electricity and gas subsidies has a greater negative impact on the poor than on the rich from an indirect perspective this article shows that the lower the per capita disposable income the higher the proportion of consumption to disposable income and the greater the indirect impact of eliminating subsidies meanwhile the impact is not only related to household income but consumer goods moreover the indirect effects of eliminating subsidies on households differ across energy types specifically eliminating electricity subsidies has the greatest effect on households followed by transportation fuel and gas we suggest that targeted supportive measures need to be taken towards the implementation of subsidy reform particularly in countries with greater inequality to minimize the negative effects on the poor

ecological economics as a policy science rhetoric or commitment towards an improved decision making process on sustainability abstract with sustainability issues currently attracting increasing political and policy attention this paper examines the impact of the rise of ecological economics in the policy world and its potential influence on the decision making process this study emphasises that ecological economics development is coevolved with and modified to fit specific social economic political and cultural contexts as a policy science ecological economics is context sensitive and action oriented explaining why it is so and what to do about it has become imperative for ecological economists this paper attempts to address the questions such as what are the macroeconomic conditions and political processes that make the formulation and implementation of ecological economic policy possible how should this alternative social reality engage with the dominant decision making process does ecological economics provide the necessary means for prescribing policy measures to achieve sustainable development endeavouring to understand these dimensions of ecological economics has been a dynamic social process and understanding this complex process might provide an opportunity to bridge the divide between policy rhetoric and reality in practice rather than maintain the status quo in order to achieve an improved decision making process on sustainability it highlights the imperative to explicitly study the institutional setting through which sustainable development policy discourse is mediated

biodiesel a new oildorado guaranteeing tax reductions and exemptions the european governments intend to increase the share of biofuels in total eu fuel consumption to 5 75 by 2010 the financial support of this eu objective is frequently justified by expected positive environmental impacts most notably the mitigation of climate change and by favorable employment effects in the agricultural sector this paper investigates the environmental and economic implications of the support of rapeseed based biodiesel as a substitute for fossil diesel based on a survey of recent empirical studies we find that the energy and greenhouse gas balances of this environmental strategy are clearly positive yet it appears to be unclear whether the overall environmental balance is also positive most importantly though biodiesel is not a cost efficient emission abatement strategy thus for the abatement of greenhouse gases we recommend more efficient alternatives based on both renewable and conventional technologies

reform of coal policies in western and central europe implications for the environment abstract a subsidy to a polluting activity increases the level of that activity and therefore the amount of pollution it generates ceteris paribus in western europe coal production is generally subsidized through price support and budgetary transfers in central europe both production and consumption are subsidized to analyse the net effects of coal policies in europe however one cannot treat them simply as equivalent to pure taxes or subsidies other distortions besides those that are price induced have to be taken into account our qualitative assessment suggests that eliminating producer and consumer subsidies to coal in europe would lead to environmental improvements and remove an important barrier to introducing greater competition in national electric power industries

taxes subsidies and insurance as drivers of united states coastal development abstract ever increasing coastal populations in the united states and worldwide are putting growing quantities of people and property at risk due to coastal disasters at the same time poorly planned development policies and practices erode the natural capital of coastal regions eliminating existing landscape protection from intense wind and waves government tax subsidy and insurance policies can encourage or discourage particular forms of development in the u s there is no consistent set of incentives or disincentives for coastal development and many programs have ambiguous or contradictory goals federal programs are highly fragmented being administered by a variety of government agencies state and local governments can also implement policies to improve coastal disaster protection but often fail to do so in other cases state and local policies designed for local economic growth work against the goals of federal policy increasing flood damage risk while relying on federal aid once disaster does strike these programs frequently lead to perverse subsidies where economically inefficient policies degrade natural capital and foster economic inequality in this study we evaluate the existing tax subsidy and insurance structures that led to coastal development patterns on the u s gulf coast over the last sixty years and propose alternative policies that could create a more sustainable just economically efficient and storm adaptive region

a note on the concept of subsidy abstract the term subsidy has been subject to many interpretations and much misuse especially as regards energy subsidies in common parlance a subsidy is a payment or tax concession from the government corden 1966 extended the concept to include in addition market transfers that is transfers from consumers to producers or vice versa resulting from government interventions that distort prices such as tariffs or price controls several summary measures have been developed to indicate the level of subsidy provided by various instruments affecting a particular sector or activity

grazing the commons an empirical analysis of externalities subsidies and sustainability abstract an empirical means of measuring externalities in the fifty states of the us is presented and the relationship between externalities subsidies and sustainability is investigated firms seeking to maximize profits create externalities thus securing implicit internal subsidies the subsidies are generally supported by those less well off and the socioeconomic energy and environmental indicators of the public sector worsen as externalities and subsidies increase implicit subsidies due to externalities in pollution control energy consumption and taxes are quantified the amount of subsidy is calculated by state and statistically compared to socioeconomic energy environmental and economic variables poverty unemployment and income disparity are found to increase significantly while income economic development attractiveness energy efficiency and environmental quality decline with increasing externalization across states an empirical method of operationalizing sustainability is presented and the relationship of sustainability to subsidies is investigated and found to be significant and negative recommendations are presented for minimizing the effects of externalities

incremental and average control costs in a model of water quality trading with discrete abatement units this paper answers three questions related to the discrete nature of pollution abatement i does a source s incremental control cost as defined by the u s environmental protection agency necessarily exceed its average control cost ii is incremental control cost a better approximation of a source s willingness to pay for abatement credits than average control cost and iii exactly how does trading in discrete and continuous abatement markets differ we find that the answer to the first two questions are both no suggesting that the u s environmental protection agency needs to refine its reliance on incremental control cost as the sole measure upon which to assess the financial feasibility of water quality trading in answer to the third question we show that the outcome of bilateral trading in the presence of discrete abatement is determined by comparing the gains from trade associated with the full sequence of possible sunk cost trading scenarios for the most common case where trading partners average control cost curves cross the trading outcome with discrete abatement is inherently sensitive to the initial allocation of abatement responsibilities

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

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

the end of economic growth a contracting threshold hypothesis this paper argues that gdp growth in both developed and developing countries has associated costs that can outweigh the benefits and thus reduce sustainable well being this conclusion is based upon the findings of empirical applications of the genuine progress indicator gpi to a range of countries in the asia pacific region the studies conducted on seven asia pacific countries indicate that in the case of five of the seven nations more recent gdp growth has reduced the sustainable well being experienced by the average citizen residing within them moreover the threshold point at which the costs of gdp growth outweigh the benefits appears to be contracting i e occurring at a much lower per capita level of gdp this paper therefore introduces a new contracting threshold hypothesis as the economies of the asia pacific region and the world collectively expand in a globalised economic environment there is a contraction over time in the threshold level of per capita gdp as a consequence the threshold point confronting growth late comers i e developing countries occurs at a much lower level of sustainable welfare than what wealthy nations currently enjoy the consequences of this for developing countries are clearly significant and require a new approach to economic development

the effects of the energy price reform on households consumption in iran abstract the substantial subsidizing of energy prices over the years has led to high energy consumption inefficiencies fiscal pressures and environmental problems in iran to address the increasing socio economic problems associated with the energy subsidies the government embarked on an aggressive energy price reform through which energy subsidies were removed and cash handouts were given to all households in 2010 in this paper i analyze the effectiveness of the energy price reform in iran by estimating energy demand elasticities for households in different income groups i apply a two stage consumer optimization model and estimate the system of energy expenditures shares using the household budget survey data for the period 2001 2008 the results show that the overall price elasticities of demand are small but income elasticities are close to one the results also indicate heterogeneous responses to energy price and income changes in different income groups specifically the urban households show stronger response to price changes but rural households particularly mid income households to income changes these findings suggest that the current policy of price increases would not solely be able to reduce energy consumption and therefore it should be geared towards increasing energy efficiency through a series of price and non price measures

environmental impairment liability as an instrument of environmental policy abstract this paper evaluates the role of liability that may arise in the context of an impairment of the environment environmental impairment liability or eil for short is analyzed as an instrument of environmental policy interrelationships between injurers victims the legal system insurers and the environment serve to show that eil may contribute to preserve the environment however peculiarities such as mass torts and uncertain behavior of courts serve to detract from the effectiveness of eil the question arises of whether these shortcomings are 1 mitigated or exacerbated by eil insurance the potential contribution of insurance to eil is found to be undermined by partial market failure which however can be alleviated by permitting the flotation of environmental risk warrants on capital markets

a flexible assurance bonding system for improved environmental management abstract current methods of regulating activities that are known or suspected to be environmentally danaging are not working well they induce legal confrontation obfuscation and government intrusion into the inner workings of firms they tend to suppress technical and social innovation aimed at long term solutions they do not mesh well with the market signals that firms use to make decisions this paper discusses some of the underlying reasons for this problem and outlines a flexible environmental assurance bonding system designed to incorporate environmental criteria and uncertainty into the market system and to induce positive environmental technological innovation in addition to direct charges for known environmental damages an assurance bond equal to the current best estimate of the largest potential future environmental damages would be levied and kept in an interest bearing escrow account the bond plus a portion of the interest would be returned if and only if the firm could prove that the suspected damages had not occured or would not occur if damages did occur the bond would be used to rehabilitate or repair the environment and to compensate injured parties by requiring the users of environmental resources to post a bond adequate to cover potential future environmental damages with the possibility for refunds the burden of proof is shifted from the public to the resource user and a strong economic incentive is provided to research the true costs of environmentally innovative activities and to develop innovative cost effective pollution control technologies

empirical analysis of the environmental and energy policies in some developing countries using widely employed macroeconomic indicators the cases of brazil china and india abstract this paper proposes an empirical analysis concerning the environmental and energy policies of some important developing countries brazil china and india today present in the international scenario with very different features than in the past the research is carried out using two of the most important macroeconomic indicators several times proposed in the field of policy analysis emission intensity ratio and energy intensity ratio moreover the emission intensity ratio is used in order to verify the empirical existence of the so called environmental kuznets curve for the three countries for what concerns this last point final results do not correspond closely to the theoretical strict formulations hypothesised in the classical environmental kuznets curve model this paper follows completing and concluding the previous one carried out by the same author for some industrialised countries after a brief but ineluctable premise considering the theoretical basic assumptions to define the question and regarding general statements the specific cases are analysed main findings show that resulting trends in these developing countries are different and furthermore they differ from those already observed in industrialised ones

household welfare implications of fossil fuel subsidy reforms in developing countries abstract with over 200 countries reaching an agreement with the stated aim of restricting global warming to well below 2 c above pre industrial levels the most comprehensive climate change agreement was recently signed though most of the hard work lies ahead it marks an important first step for the collective global community to address climate change fossil fuels continue to remain one of the largest contributors to greenhouse gas emissions and for many developing countries high levels fossil fuels continues to enable an overconsumption of fossil fuels given the sensitivity of governments to subsidy reforms this study examines the household welfare implications of the removal of fossil fuel subsidies it finds that while welfare implications are unambiguously positive for government the results are mixed for private households although in an overwhelming majority of cases the results are positive however even in the cases where the welfare implications are negative for private households we find that it is possible for governments to carry out the reforms in such a way as to be welfare improving to households incomes by compensating them with some of the fiscal savings gained from the subsidy reform

an equilibrium framework for global pollution problems abstract the paper analyzes global pollution problems from the point of view of the benefit approach to the allocation of public costs special attention is paid to the possibility that the optimum abatement vector may have negative elements an appropriate cost share equilibrium is defined and characterized and conditions under which the equilibrium is beneficial to all parties are derived an implementation mechanism whose nash equilibrium yields positive abatement levels under appropriate conditions is described

limits to environmental bonds abstract bonds have recently been promoted as an alternative tool to control environmental damages particularly in those instances when the innovative activities of a firm have uncertain future impacts under this mechanism a firm would post a bond ex ante forfeiting all or a portion of the bond if its activities harmed environmental resources while the benefits of bonds have been developed there has been little systematic effort to explore their limitations in contrast the labor literature has extensively studied the limits of bonds as a mechanism to prevent worker shirking using insights from this parallel problem this paper explores the limits to environmental bonds focusing on the problems of moral hazard liquidity constraints and legal restrictions each limit offers a challenge to the success of environmental bonds we explore the use of bonds in surface mining and agricultural nonpoint pollution as motivating examples we also consider how other incentive schemes suggested by the labor literature might prove useful in the context of environmental management we consider the labor mechanisms of efficiency wages increasing wage profiles trust funds and rank order tournaments

efficiency and applicability of economic concepts dealing with environmental risk and ignorance abstract the paper examines the efficiency and applicability of various economic concepts dealing with environmental uncertainty their applicability is analysed by classifying environmental uncertainty according to different criteria using such a structure it can be shown that while the economic concepts are able to deal satisfactorily with some types of environmental uncertainty they are unable to deal with others adequately the analysis of efficiency distinguishes between environmental risk in which the decision maker is aware of the distribution function of the random variables and ignorance in which the decision maker does not know the relevant distribution functions the concept of a risk premium proposed by siebert the policy recommendation to promote integrated technologies and the environmental assurance bonding system developed by costanza and perrings are examined in terms of efficiency and applicability the analysis reveals the following i the application possibilities of the three concepts differ significantly ii a concept which concentrates on the reduction of risk may lead to an increase in ignorance iii while an economic concept may be efficient in the context of risk it can be inefficient when ignorance exists iv a trade off exists between the possibility to precisely state whether an economic concept is efficient and the scope of its applicability

factors affecting wood energy consumption by u s households about 23 of energy derived from woody sources in the u s was consumed by households of which 70 was used by households in rural areas in 2005 we investigated factors affecting household level wood energy consumption in the four continental u s regions using data from the u s residential energy consumption survey to account for a large number of zero observations i e households that do not burn wood left censored tobit models were estimated urban rural location is a key determinant of level of household wood energy consumption wood energy consumption elasticity with respect to non wood energy price changes was 1 55 at the u s level and a much higher 2 30 among rural households while household wood energy consumption was affected primarily by non wood energy price in rural areas it was influenced mainly by household size and level of income in urban areas elasticity of wood energy consumption with respect to income can be positive or negative depending on household urban rural location region and income level newer houses were found to use less wood energy than older ones and greater urbanization was found to have negative effect on wood energy use our findings suggest that policies reducing relative wood energy cost or increasing non wood energy prices in the residential sector will result in greater wood energy consumption in the u s the effect of policies may vary by region and are likely to be more effective in u s rural areas and in the u s midwest in particular

absorptive capacity coauthoring behavior and the organization of research in drug discovery we examine the interface between for profit and publicly funded research in pharmaceuticals firms access upstream basic research through investments in absorptive capacity in the form of in house basic research and pro publication internal incentives some firms also maintain extensive connections to the wider scientific community which we measure using data on coauthorship of scientific papers between pharmaceutical company scientists and publicly funded researchers connectedness is significantly correlated with firms internal organization as well as their performance in drug discovery the estimated impact of connectedness on private research productivity implies a substantial return to public investments in basic research

impact of energy subsidies on energy consumption and supply in zimbabwe do the urban poor really benefit abstract twenty percent of zimbabwe s urban poor households are still to be connected to the grid the majority of these households are poor there are several reasons why the zimbabwe urban poor are still not connected to the grid the most important one being the household incomes and the cost of different sources of energy in order to facilitate wider usage of electricity by the poor the policy makers have introduced a subsidy policy the objective of this paper is to ascertain the extent to which the poor urban households could afford the cost of electricity with or without subsidies this gives an indication on whether contrary to the current thinking subsidies are decisive for the affordability of electricity by the urban households the paper also examines the distribution of the subsidies amongst the different urban household income categories and other economic sectors furthermore the impact of such subsidies on the utility s finances is assessed

welfare implication of reforming energy consumption subsidies abstract reforming energy consumption subsidies in particular for fossil fuels has been frequently referred to as a quick win policy to enhance environmental mitigation in addition the removal of such subsidies may release a sizeable portion of a country s national budget for use on more productive targets one of the most recognized challenges of such reform is selling the new energy prices to citizens particularly those with a more fragile purchasing power several empirical and technical studies have prescribed that the reform might be supported by a direct compensation mechanism in order to ensure feasibility this is what was done during the recent energy subsidy reform in iran however the compensation mechanism implemented in iran s reform was successful at the beginning but did not proceed as expected this has raised questions about the feasibility and sustainability of the direct compensation mechanism and even of the reform policy itself in this paper we consider a stylized model where direct compensation is the instrument proposed to restore consumers utility against increased energy prices we find that when prices of other goods are affected by the announced reform policy the feasibility of a subsidy reform critically depends on the value of certain parameters the initial subsidization rate the share of energy in the consumers bundle and the energy portion of price of other goods

from the ground up ecofeminism and ecological economics abstract speaking from the margins ecofeminist analysis exposes many of the assumptions of neoclassical economics as gender biased and as anti ecological it identifies the abstract individual of neoclassical economics as a privileged male individual whose apparent autonomy is predicated on the oppression of women marginal people and nature thus ecofeminists tell a different story about economic man from the grounds of others experience up ecofeminism points to the limits of models of sustainability built on extending market rationality to non market spheres of life ecofeminist economics contains a creative tension between a commitment to social justice and a determination not to colonize the wild

price and expenditure elasticities of residential energy demand during urbanization an empirical analysis based on the household level survey data in china abstract urbanization one of the most obvious characteristics of economic growth in china has an apparent lock in effect on residential energy consumption pattern it is expected that residential sector would become a major force that drives china s energy consumption after urbanization process we estimate price and expenditure elasticities of residential energy demand using data from china s residential energy consumption survey crecs that covers households at different income levels and from different regional and social groups empirical results from the almost ideal demand system model are in accordance with the basic expectations the demands for electricity natural gas and transport fuels are inelastic in the residential sector due to the unreasonable pricing mechanism we further investigate the sensitivities of different income groups to prices of the three types of energy policy simulations indicate that rationalizing energy pricing mechanism is an important guarantee for energy sustainable development during urbanization finally we put forward suggestions on energy pricing reform in the residential sector based on characteristics of china s undergoing urbanization process and the current energy consumption situations

hard coal subsidies a never ending story abstract in germany hard coal has been subsidized for almost half a century despite the declining significance of hard coal production for the domestic labor market the subsidies have continued to increase until the middle of the last decade reaching a peak at 6 7 billion in 1996 while these subsidies have been continually shrinking since then settling at 2 7 billion in 2005 it is very likely that hard coal support will be extended in germany well into the next decade and even beyond this article questions the main arguments raised by the proponents of hard coal subsidization in germany and other eu countries most importantly in addition to the drain these subsidies impose on public budgets substantial opportunity costs are implied leading funds away from alternative more beneficial public investments from a social welfare perspective we therefore recommend the rapid abolition of these subsidies not only in germany where in real terms the accumulated amount of subsidies has now far exceeded 165 billion but also all across europe

trade and the political economy of redistribution this paper shows how international trade affects the support for policies which redistribute income between workers across sectors and how the existence of such policies changes the support for trade liberalization workers who are imperfectly mobile across sectors vote on whether to subsidize ailing sectors thereby redistributing income but also distorting the labor allocation we present three main findings first redistributive policies are more likely to arise in a small open than in a closed economy for a broad range of parameters second if a redistributive policy is adopted in both situations income differences across sectors tend to be lower in the open economy third the possibility to redistribute income across sectors raises the political support for trade liberalization in the first place

sustainable land use management under biodiversity lag effects the destruction of natural habitats for agricultural production results in local biodiversity loss biodiversity loss in turn affects agricultural production indirectly through a range of biodiversity dependent ecosystem services land conversion thus results in a negative externality mediated by changes in biodiversity when the consequences of this externality are delayed in time lack of internalization results in overshoot and collapse dynamics which are undesirable from a sustainability perspective here we emphasize the importance of forward looking policies for the long term sustainability of human nature interactions we show that the internalization of this externality through a land tax can result in several win win effects in the long run first more biodiversity is preserved at equilibrium which increases the carrying capacity and total well being of the human population second a taxation path that maximizes the discounted sum of human utilities prevents or greatly alleviates overshoot and collapse crises thus increasing the sustainability of the system in particular this result holds in the case of imperfect information regarding the precise temporal dynamics of biodiversity loss suggesting that the design of efficient land use management policies is possible despite incomplete ecological data this study highlights the need to internalize biodiversity dependent externalities through economic incentives especially under uncertainty regarding long term ecological dynamics

planning for sustainability as a learning concept abstract the major theme of the following discussion is the importance of a transdisciplinary approach to guide sustainability related planning and management activities the proposed approach involves much more than the usual interaction between partners from different disciplines a revised process is needed to allow real cooperation in sustainability planning this process will require a more open recognition of the subjective priorities that become the framework of sustainable development issues of various interest groups and disciplines the sustainable development agenda should be more geared towards learning processes than projected future outcomes learning is enhanced through a participatory framework inclusive of stakeholder interests insights from a broad range of disciplinary areas including the science of complexity sociology philosophy law economics and management are presented to support this position the conventional stranglehold of disciplinary thinking in policy circles limits the capacity of our decision makers to unravel the complexity of all real world environmental policy and management problems policy making needs to embody respect for that complexity and allow flexibility to promote perpetually evolving learning as a fundamentally transdisciplinary framework ecological economics has some prospect to represent these interests in a purposeful and necessarily pragmatic way

international environmental problems a simple taxonomy of international environmental problems is developed based on economic considerations the unidirectional externalities are illustrated by the case of one upstream and one downstream country the main problem in this case is an informational one the analysis of regional reciprocal externalities is illustrated by the acid rains in europe it is shown that an efficient solution could be achieved by transferable export rights finally global external problems are discussed with reference to greenhouse effects and extinction of species copyright 1990 by oxford university press

a finnish soviet acid rain game noncooperative equilibria cost efficiency and sulfur agreements abstract this study analyzes cost effectiveness in environmental cooperation between finland and the soviet union it is assumed that the aim of both countries is to attain a given target deposition level at minimum possible sulfur abatement costs cost effective cooperation is compared to noncooperative equilibrium and to the agreement on sulfur emissions between these two countries it is shown that the agreement is not cost effective implies higher abatement costs than under noncooperation and is strategically unstable however the cost differences and the incentives to cheat are small the computations reveal that the main source of potential cooperation benefits is not asymmetrical emission transportation or differences in abatement costs but rather different target deposition levels for finland and the soviet union

the political economy of coal subsidies in europe abstract both the mining and the burning of coal is polluting so we might expect to observe taxes on coal production and consumption yet several countries of western europe subsidize coal production and most east european countries subsidize coal consumption the first part of this paper shows that those subsidies which are emulated by other rich and poor countries respectively have become enormous neoclassical political economy is used to examine why governments adopt such inappropriate policies when they are so wasteful of resources and damaging to the environment several new and offsetting political forces have been at work in western europe in recent years though causing some countries to dismantle their coal producer subsidies the paper concludes that these pressures for reform will continue to operate in the few remaining protectionist countries if coupled with more commercial diplomatic pressure from coal exporting countries they could be sufficient to see the end of such protection by early next century
