trade s dynamic solutions to transboundary pollution abstract this study develops a differential game to examine the effects of trade liberalization on transboundary water pollution water pollution is due to wastewater emissions from countries in a shared waterway along the u s mexico border with available data of pollution abatement costs public health damages and trade benefits noncooperative and cooperative games are examined with changes in trade policy and public health damages results show trade liberalization leads mexico to curtail pollution in both games cooperation and trade liberalization limit emissions from both countries and curtail strategic behavior of the united states from mexico s pollution control efforts in the noncooperative game

externalities property rights and the allocation of resources in major league baseball most economists who have analyzed professional baseball have concluded that two distinctive features of its labor market the reserve clause and player draft influence the distribution of wealth between players and owners but do not affect the allocation of playing talent among teams such conclusions which are strongly at variance with laymen s views of such matters are derived from theoretical considerations rather than empirical examinations our paper examines data from the two decades of major league history and concludes that on the basis of that data the empirical generalizations of previous economists do not appear to be justified

dynamic nonpoint source pollution control policy ambient transfers and uncertainty when a regulator cannot observe or infer individual emissions corrective policy must rely on ambient pollution data assuming this kind of environment we study a class of dierential games of pollution control with prot functions that are polynomial in the global pollution stock given an open loop emissions strategy satisfying mild regularity conditions an ambient transfer scheme is exhibited that induces it in markov perfect equilibrium mpe proposed transfers are a polynomial function of the dierence between actual and desired pollution levels moreover they are designed so that in mpe no tax or subsidy is ever levied their applicability under stochastic pollution dynamics is studied for a symmetric game of polluting oligopolists with linear demand we discuss a quadratic scheme that induces agents to adopt markovian emissions strategies that are stationary and linearly decreasing in total pollution total expected ambient transfers are non positive and their magnitude is linearly increasing in physical volatility the size of the economy and the absolute value of the slope of the inverse demand function however if the regulator is interested in inducing a constant emissions strategy then in expectation transfers vanish the total expected ambient transfer is compared to its point source equivalent

pollution control under a possible future shift in environmental preferences abstract we examine how the possibility of a future shift in environmental preferences affects optimal pollution emissions for example is a more stringent carbon cap called for if excessive carbon emissions today may trigger a shift toward greener preferences in the future in contrast to the related literature which largely focuses on regime shifts in damages not preferences we find that the possibility of a shift in environmental preferences can induce higher or lower optimal current emissions this hinges on an economically interesting interplay between the magnitude of the possible shift whether the shift is endogenous and the magnitude of environmental damages this helps reconcile the tension between the conservationists view of pollution reduction to reduce damage and lessen the likelihood of regime shift and the traditional economic rationale emphasizing risk and discounting

global warming irreversibility and learning a number of economists have argued that the literature on the irreversibility effect implies that current abatement of greenhouse gas emissions should be greater when there is the possibility of obtaining better information in the future about the potential damages from global warming than when there is no possibility of obtaining better information in this paper we show that even the simplest model of global warming does not satisfy either of epstein s 1980 sufficient conditions so it is not possible to use epstein s analysis to tell whether the irreversibility effect applies to models of global warming we derive an alternative sufficient condition for the irreversibility effect to hold

the acid rain differential game this paper considers an acid rain differential game countries emit sulphur which is partly transferred to other countries depositions above critical loads ultimately destroy the soil countries face a trade off between the costs of emission reductions and the damage to the soil due to the depletion of the acid buffers because of the transboundary externalities the outcome will depend on whether the countries cooperate or not this paper presents the cooperative outcome and the open loop and markov perfect nash equilibria of the acid rain differential game it will be shown that the depositions always converge to the critical loads but the steady state levels of the buffer stocks differ the theory is used to analyse the acid rain differential game for sulphur between great britain and ireland finally some results are given for the whole of europe

response to embodied energy and emergy analyses of a concentrating solar power csp system 2012 while emergy analysis i e emergy synthesis environmental accounting was developed in the early 1980s by h t odum building upon his seminal work outlining the energy basis for man and nature the method is still developing some very important aspects of the method such as the global baseline for renewable emergy and how the emergy yield ratio eyr a critical index for implicating the contribution of a process to society is to be calculated are still under debate in the scientific community this makes it all the more critical that when an emergy analysis is done all methodology is laid bare and justified unfortunately zhang et al 2012 energy policy 42 pp 232 238 is deficient in doing so in the response below i lay out the problems i observed in the paper and propose a revision to their analysis i should note that no issues were found with the embodied energy portion of the analysis and the inconsistencies with accepted methodology were likely due to an unfamiliarity with the emergy method

international pollution control cooperative versus noncooperative strategies abstract international pollution control involving two neighboring countries is modeled as a simple two player dynamic game each country produces a good that is consumed by domestic households production of each consumption good results in emissions of pollutants households in each country derive utility from the consumption of the domestically produced good but incur costs through the total stock of pollution stock externality in this setting we characterize cooperative as well as noncooperative pollution control strategies of the governments of the two countries that maximize the discounted stream of net benefits of a representative consumer it turns out that when the governments are restricted to use linear strategies noncooperative behavior results in overall losses for both countries if on the contrary governments use nonlinear markov perfect strategies and the discount rate is small enough a pareto efficient steady state pollution stock can be supported as a differentiable subgame perfect equilibrium thus the emergence of first best solutions cooperative outcomes does not require any institutional arrangements threats retaliation etc but can be brought about through the use of nonlinear markov perfect equilibrium strategies

a dynamic model of conflict and appropriation abstract this paper presents an extension of a static model of economic conflict analyzed by hirshleifer 1991 1995 and skaperdas 1992 to an infinite horizon differential game our aim is to highlight the strategic role of appropriation among a smaller group of agents in an intertemporal context the model yields the conclusion that there exists a unique linear nonlinear markov perfect equilibrium strategy even when strategies are defined over the entire state space we demonstrate that partial cooperation can be seen as a long run response to conflict moreover a decrease in the effectiveness of appropriation the depreciation rate of a common pool stock the rate of time preferences or an increase in the degree of noise improves the degree of partial cooperation and thus welfare in an anarchic society

ownership of property rights and the allocation of talents under the reserve clause system that assigns the property rights on the major league baseball players services to teams player transfers are negotiated between teams without the involvement of players in contrast under the current free agency system players with free agent status negotiate directly with potential suitors thus the system assigns the property rights to players using data extracted from the baseball archive http baseball1 com this article examines the effect of the change in the property rights assignment on the allocation of talents across teams we find that the change increased large market teams shares of veteran all star players and the concentration of senior players

uncertainty learning and international environmental policy coordination in this paper we construct a simple model of global warming which captures a number of key features of the global warming problem i environmental damages are related to the stock of greenhouse gases in the atmosphere ii the global commons nature of the problem means that these are strategic interactions between the emissions policies of the governments of individual nation states iii there is uncertainty about the extent of the future damages that will be incurred by each country from any given level of concentration of greenhouse gases but there is the possibility that at a future date better information about the true extent of environmental damages may become available an important aspect of the problem is the extent to which damages in different countries may be correlated in the first part of the paper we consider a simple model with two symmetric countries and show that the value of perfect information is an increasing function of the correlation between damages in the two countries in both the cooperative and non cooperative equilibria however while the value of perfect information is always non negative in the cooperative equilibrium in the non cooperative equilibrium there is a critical value of the correlation coefficient below which the value of perfect information will be negative in the second part of the paper we construct an empirical model of global warming distinguishing between oecd and non oecd countries and show that in the non cooperative equilibrium the value of perfect information for oecd countries is negative when the correlation coefficient between environmental damages for oecd and non oecd countries is negative the implications of these results for international agreements are discussed

nonparametric nonlinear cotrending analysis with an application to interest and inflation in the united states given the assumption that the components of a vector time series are stationary around nonlinear deterministic time trends nonlinear cotrending is the phenomenon that one or more linear combinations of the time series are stationary around a linear trend or a constant hence the series have common nonlinear deterministic time trends in this article i develop nonparametric tests for nonlinear cotrending and i derive nonparametric estimators of the cotrending vectors i apply this approach to the federal funds rate and the consumer price index inflation rate in the united states using monthly data to analyze the price puzzle

racial integration as an innovation empirical evidence from sports leagues this paper treats racial integration as an innovation in economic process in which economic entities find it advantageous to utilize potentially more productive inputs previously unavailable due to law custom or managerial discretion data on the racial integration of major league baseball and atlantic coast conference basketball are employed to address this issue the central question examined is which type of team integrated first losers or winners the results strongly support the idea that entrepreneurship trumps competitive rivalry that is winning teams led the process of racial integration jel li j7 one of the watershed events in u s history is the struggle to achieve a racially integrated society while the civil rights laws and court rulings in the 195o s 196o s and 197o s are among the major changes in public policy that gradually led to a breakdown of jim crow rule in the american south other changes in law and custom also motivated the process of racial integration across time and place indeed segregation was not limited to the south but was a prominent feature of many national organizations and markets despite the extensive commentary on these events from various perspectives there has been very little economic analysis of the actual process of racial integration economists have focused their efforts on the economics of discriminatio n while the actual process by which individuals firms and

the externalities problem of transboundary and persistent pollution abstract this paper deals with implementing the efficient allocation of transboundary and persistent pollution in particular we adapt varian s compensation mechanism varian a solution to the problem of externalities when agents are well informed amer econ rev 85 1994 1278 1293 to cover situations in which pollutants extend to neighboring regions and their effects persist over time the main contribution of this paper is the design of a mechanism that implements in subgame perfect equilibrium the efficient pollution levels in this context

emergy based ecological footprint analysis for a mega city the dynamic changes of shanghai abstract to move towards sustainable urban development interactions between economic and ecological systems should be further investigated due to their coupled relations in this study we propose an emergy based ecological footprint eef analysis framework shanghai was selected as a case study city to see its dynamic changes from 2007 to 2016 the results show that shanghai had a large ecological deficit an extremely high ecological footprint intensity and a poor coordination relationship between its ecological system and its economic system indicating a great ecological challenge that it is facing the uneven distribution of its emergy ecological footprint is mainly due to the large share of fossil fuels land type but with the city s great efforts the overall ecological pressure has been reduced and the coordination relationship has also been improved while the local economy is still booming pearson correlation analysis further indicates that the city s policy on developing tertiary industry has resulted in a positive effect on improving the coordinating relationship the ratio between the output value of heavy industry and gross industrial output value has the most negative correlation with the coordinating relationship finally policy recommendations are raised by considering the local realities these recommendations can also provide valuable insights to other megacities with similar challenges

a dynamic game of emissions pollution with uncertainty and learning we introduce learning in a dynamic game of international pollution with ecological uncertainty we characterize and compare the feedback non cooperative emissions strategies of players when the players do not know the distribution of ecological uncertainty but they gain information learn about it we then compare our learning model with the benchmark model of full information where players know the distribution of ecological uncertainty we find that uncertainty due to anticipative learning induces a decrease in total emissions but not necessarily in individual emissions further the effect of structural uncertainty on total and individual emissions depends on the beliefs distribution and bias moreover we obtain that if a player s beliefs change toward more optimistic views or if she feels that the situation is less risky then she increases her emissions while others react to this change and decrease their emissions

sustaining cooperation in a differential game of advertising goodwill accumulation abstract the paper suggests a differential game of advertising competition among three symmetric firms played over an infinite horizon the objective of the research is to see if a cooperative agreement among the firms can be sustained over time for this purpose the paper determines the characteristic functions value functions of individual players and all possible coalitions we identify an imputation that belongs to the core using this imputation guarantees that in any subgame starting out on the cooperative state trajectory no coalition has an incentive to deviate from what was prescribed by the solution of the grand coalition s optimization problem

learning and stock effects in environmental regulation the case of greenhouse gas emissions abstract this paper concerns the optimal regulation of greenhouse gases that lead to global climate change in particular we focus on uncertainty and learning which over time resolves uncertainty we present an empirical stochastic model of climate economy interactions and present results on the tension between postponing control until more is known vs acting now before irreversible climate change takes place uncertainty in our model is in the damage caused by global warming the results suggest that a temporary carbon tax may dominate a permanent one because a temporary tax may induce increased flexibility

strategic exploitation with learning and heterogeneous beliefs abstract we study the effect of learning with heterogeneous beliefs on the exploitation of a renewable common pool resource to that end we extend the great fish war model of levhari and mirman 1980 to a learning environment in which several agents interact strategically and learn about the distribution of the stochastic evolution of the resource we find that the effect of anticipation of learning with heterogeneous beliefs is twofold first the anticipation of learning makes future payoffs more uncertain which induces the agents to decrease present exploitation due to the precautionary motive second under heterogeneity of beliefs there is a differential informational externality that induces the agents to increase or decrease present exploitation we also perform a comparative analysis on the cournot nash equilibrium with learning by studying the effect of optimism and riskiness on resource exploitation

uncertainty learning and heterogeneity in international environmental agreements this paper concerns the formation of international environmental agreements under uncertainty about environmental damage with different models of learning complete learning partial learning or no learning the results of the existing literature are generally pessimistic the possibility of either complete or partial learning generally reduces the level of global welfare that can be achieved from forming an iea relative to no learning that literature regards uncertainty as a parameter common to all countries so that countries are identical ex ante as well as ex post in this paper we extend the literature to the case where there is no correlation between damage costs across countries each country is uncertain about a particular parameter in our case the benefit cost ratio drawn from a common distribution but ex post each country s realized parameter value is independently drawn consequently while countries remain identical ex ante they may be heterogeneous ex post we show that this change reinforces the negative conclusions about the effects of partial learning on international environmental agreements but under certain conditions moderates the negative conclusions about the effects of complete learning

influence of sewage treatment on china s energy consumption and economy and its performances abstract the sewage treatment industry may affect china s energy saving and economic growth related goals to some degree this study investigated influence of sewage treatment on china s energy consumption and economic growth and its performances from 2008 to 2013 we adopted a set of indicator system based on energy emergy and money to depict these interactions including energy use per unit emission reduction euer cost per unit emission reduction cuer environmental benefit per unit investment ebui ratio of energy consumption from sewage treatment to national total energy consumption rest ratio of cost of sewage treatment to the gross domestic product rcsg structural coordination degree of sewage treatment scds and scale harmony degree of sewage treatment shds here emergy was used to quantify the environmental impact of water pollutants the study results show that energy efficiency of sewage treatment keeps relatively stable the economic cost of sewage treatment increases obviously the environmental performance of sewage treatment investment slightly rises and the sewage treatment has an increasing impact on the energy consumption and economic growth of this country as far as the relationships between different indicators or factors are concerned the structure of china s sewage treatment industry worsens obviously due to rising energy consumption and economic cost meanwhile the relationship between economic cost and energy consumption for sewage treatment domestic water consumption and discharged sewage s impact seriously deteriorated finally some corresponding issues are discussed and the related policy implications are put forward

an emergy evaluation of complexity information and technology towards maximum power and zero emissions abstract this paper mostly deals with the role of energy matter and information flows within both environmental and human dominated systems sustainable growth and development of both kinds of systems require optimum use of available resources for maximum power output as suggested by lotka s maximum power principle lotka aj contribution to the energetics of evolution in proceedings of the national academy of sciences of the united states of america vol 8 1922 p 147 50 lotka aj natural selection as a physical principle in proceedings of the national academy of sciences of the united states of america vol 8 1922 p 151 5 recently restated by odum odum ht maximum power and efficiency a rebuttal ecol model 1983 20 71 82 odum ht environmental accounting emergy and environmental decision making n y john wiley sons 1996 as maximum em power principle within the framework of his emergy synthesis approach in times of declining resources this principle translates into increased efficiency and optimum use of any kind of waste and co products ecosystems and any self organizing systems always apply this strategy and their selection evolution mechanisms are based on their ability of growing on any untapped resource available in order to do so they increase the number of components and patterns for resource degradation in order to optimize the resource throughput and power output such a strategy also applies to human dominated economic systems where the ability of dealing with co products and wastes by means of appropriate designs as well as reuse and recycling processes may lead to zero emission patterns increased complexity optimal resource throughput minimization of emissions resource exchange among system s components and be the key for successful and sustainable development in this paper life cycle assessment and emergy synthesis approaches are suggested as joint tools for qualitative and quantitative evaluation of progresses towards industrial symbiosis and more sustainable production and consumption patterns within a zero emission framework

efficiency inducing taxation for polluting oligopolists abstract we show that there exists a time independent tax rule that guides polluting oligopolists to achieve the socially optimum production path the optimal tax is dependent on the current pollution stock and it may be negative when the pollution stock is low a surprising result is that the optimal tax rule may give firms a subsidy for an initial time interval even though under laissez faire their output always exceeds the socially optimal output this subsidy however induces firms to produce less than they would under laissez faire

the impact of foresight in a transboundary pollution game abstract we study the impact of foresight in a transboundary pollution game i e the ability of a country to control its emissions taking into account the relationship between current emissions and future levels of pollution and thus on future damages we show that when all countries are myopic i e choose the laisser faire policy their payoffs are smaller than when all countries are farsighted i e non myopic however in the case where one myopic country becomes farsighted we show that the welfare impact of foresight on that country is ambiguous foresight may be welfare reducing for the country that acquires it this is due to the reaction of the other farsighted countries to that country s acquisition of foresight the country that acquires foresight reduces its emissions while the other farsighted countries extend their emissions the overall impact on total emissions is ambiguous moreover our results suggest that incentive mechanisms that involve a very small possibly zero present value of transfers can play an important role in inducing a country to adopt a farsighted behavior and diminishing the number of myopic countries these incentives would compensate the myopic country for the short run losses incurred from the acquisition of foresight and can be reimbursed by that country from the gains from foresight that it enjoys in the long run

adaptation mitigation and risk an analytic approach abstract the adaptation vs mitigation dilemma is considered by analyzing a simple dynamic model of managing a polluting process subject to the risk of abrupt occurrences of harmful events the occurrence hazard can be mitigated by reducing the polluting emissions while the occurrence damage can be controlled via investments in adaptation activities a full dynamic characterization of the optimal mitigation adaptation processes is presented the adaptation and mitigation policies interact strongly and the evolution in time of each is affected by the option to implement the other the conditions under which adaptation investments should begin promptly take place after some delay or be avoided altogether are derived in terms of some key model parameters

can uncertainty alleviate the commons problem global commons problems such as climate change are often affected by severe uncertainty the paper examines the effect of uncertainty on pollution emissions and welfare in a strategic context we find that emissions are always lower under uncertainty than under certainty reflecting risk reducing considerations we show that uncertainty can have a net positive impact on the welfare of risk averse polluters we extend the analysis to increases in risk increases in risk aversion and to risk heterogeneity jel d81 c72 q54 h23

on the evolution of competitive balance the impact of an increasing global search the coase theorem maintains that where free market precepts exist the allocation of property rights does not impact the distribution of resources an application to major league baseball suggests that institutions such as free agency and the reverse order amateur draft would not impact player distributions and therefore would not impact competitive balance the present study finds that the distribution of wins is generally consistent with the precepts of the coase theorem and therefore suggests a course for those who wish to alter the level of competitive balance major league baseball should increase its focus on expanding the size of its labor pool jel o15 l83 c22

strategic behavior and efficiency in the common property extraction of groundwater groundwater has always been regarded as a common property resource where entry is restricted by land ownership and private exploitation is inefficient in 1980 gisser and sanchez presented a first estimation of this inefficiency cornparing socially optimal exploitation with private competitive exploitation using a model with linear water demand average extraction cost independent of the rate of extraction and linearly decreasing with respect to the water table level they characterized the private exploitation of the aquifer assuming that farmers are myopic and choose their rate of extraction to maximize their current profits whereas optimal exploitation is obtained by maximizing the present value of the stream of aggregate profits their results show that if the storage capacity of the aquifer is relatively large the difference between the two systems is so small that it can be ignored for practical consideration this result has been called the gisser sanchez rule by nieswiadomy 1985 and it has and important policy implication regulation of the resource does not seem justified since the profits it brings are not very high 1

analysis of nash equilibria in a class of capital accumulation games in a simple capital accumulation game we study existence and dynamic properties of the cooperative solution two kinds of markov perfect equilibria mpe and a trigger strategy equilibrium in the cooperative solution the stock always converges towards a steady state this property is shared by our first mpe whereas the second type of mpe may result in complicated dynamics a pareto comparison of both mpe depends on the parameter specifications but can turn out either way finally we show how the players can achieve the efficient payoffs of the cooperative solution as an equilibrium outcome by using trigger strategies

on the evolution of competition an application of nonlinear tests a corollary of the coase theorem maintains that where free market precepts exist the allocation of property rights would not impact the level of competition within an industry within the major league baseball industry for example the theorem would suggest that institutional arrangements such as free agency would not impact player distributions and therefore would fail to alter competitive balance in order to examine this implication the present paper investigates the univariate behaviour of competition balance in the end it appears that an increased labour pool rather than institutional changes is responsible for movements in competitive levels within the industry specifically the evidence suggests that competitive balance measures are trend stationary however the trend is nonlinear and is common to baseball s labour pool i e the two co trend

the inclusion of economic and environmental factors in the ecological cumulative exergy consumption analysis of industrial processes abstract resource economic and environmental impacts are three major factors in the evaluation of industrial processes all of them might imply certain contributions of ecosystems services a comprehensive accounting of these factors is critical to sustainability assessment of industrial activities at the ecological scale ecological cumulative exergy consumption ecec analysis is a promising approach to address these issues however the current knowledge on ecec is incomplete especially in economic investment and environmental impact in this paper ecec analysis is extended to quantify purchased resources and pollutant emissions of industrial production accordingly an extended ecec framework is proposed integrating the resource economic and environmental factors furthermore for better understanding of sustainability a concept of ecological life cycle cost elcc is put forward revealing the relationship between the ecec and traditional economic evaluation finally a case study of china s raw coal production is used to illustrate the features of these proposed frameworks the ecec and elcc analyses indicate the great ecological influence of raw coal which has been underestimated by the traditional assessment approaches

regime shifts and uncertainty in pollution control we develop a simple model of managing a system subject to pollution damage such as climate change under the risk of an abrupt and random jump in the damage function the model allows the full dynamic characterization of the optimal emission policies under uncertainty the results imply precautionary behavior in contrast with the ambiguous outcomes reported in the literature for models of catastrophic occurrences the framework is used to analyze the adaptation vs mitigation dilemma and provides a simple criterion to determine when adaptation activities should be undertaken

sustainability analysis of a society based on exergy studies a case study of the island of samso denmark abstract the danish island samso has since 1997 initiated a process through which the island should reach a state where it would be able to supply its own energy such a situation was reached since 2005 after having established 21 windmills and the island is now a net exporter of electricity to the danish power network at the same time the buildings in the more habituated areas were connected to 4 district heating plants which generate heat from combustion of straw in some cases combined with supplementary inputs from photo thermal devices meanwhile certain activities on the island such as running the ferries cars factories and heating in more distant areas are still dependent on significant input of fossil fuels the inhabitants have recently stated a wish to move on towards being independent of fossil fuels in 2030 and carbon neutral during the next decades as a consequence the idea came up to develop a method for the sustainability analysis of a society which would assist in governing the transitional process in the direction of increasing sustainability therefore a framework has been developed based on the concept exergy that may reveal where large consumptions are taking places such areas are likely to be sensible targets for action or at least increased attention basic methods have been developed that allows to account for infrastructure transfers inputs and outputs and consumption in terms of exergy and taking into account whether the exergy storages or flows can be considered to be renewable or not the framework has been developed for six societal sectors the energy sector the public sector the private households the agricultural sector the industry commerce and trade sector and nature nature is here considered an activity that provides the society with an exergy that may also be of value to our societies often referred to as ecosystem services based on the estimated amount of infrastructure and transfers inputs and outputs a number of sustainability indicators have been developed that may be monitored over time and which may serve to indicate whether potential measures undertaken also lead the society in the right direction an attempt to evaluate the potential importance of wastes has also been carried out as in organic waste could play an important role in acquiring the amount of bio diesel required to run the ferries in the future the results demonstrate that the already existing overhead in production of electricity leaves the island with many options and a great opportunity to be independent of fossil fuels in near future in fact it might well be that socio economical perspectives will turn out to be the more severe obstacles in the transition process adjacent to this work a carbon model has also been set up to reveal the consequence of proposed measures and strategies to the carbon budget of the island jorgensen and nielsen 2014

optimal control for transboundary pollution under ecological compensation a stochastic differential game approach abstract to account for previously ignored yet widely observed uncertainty in nature s capability to replenish the natural environment in ways that should inform ideal design of ecological compensation ec regimes this study constructs a stochastic differential game sdg model to analyze transboundary pollution control options between a compensating and compensated region equilibrium strategies in the stochastic two player game inform optimal control theory and reveal a welfare distribution mechanism to form the basis of an improved cooperative game contract a case based numerical example serves to verify the theoretical results and supports three key insights first accounting for various random disturbance factors the probabilistic pollutant stock in stackelberg non cooperative game exceeds that of a cooperative game situation second the ec mechanism provides long term effective incentives only when the marginal losses of environmental damage in the compensating region are more than twice that of the compensated region achieving a pareto optimal equilibrium relies upon the attainment of a dynamic allocation ratio derived from the analysis of a robust welfare allocation mechanism third cross region cooperation reliably outperforms stackelberg non cooperation due to either overwhelming incumbent economic interests or high abatement costs this study illuminates the importance of balancing both parties interests within an ec agreement while reducing uncertainty around unobserved environmental factors during ex ante negotiations

international aspects of pollution control pollution is a by product of production is only gradually dissolved by the environment and crosses national borders the market outcome ignores the adverse effects of pollution and thus yields higher levels of output and pollution than would prevail under a supranational social planner which does care about pollution in practice governments often do not cooperate and this leads to outcomes of pollution and production in between the market outcomes and the outcomes under supra national social planning absence of precommitment leads to lower emission charges less cleaning up activities and more pollution appropriate levels of emission charges under the various outcomes are a result of this analysis attention is also paid to investment in clean technology the debate between optimists who believe that higher production is compatible with sound environmental policy and pessimists can be analysed in this way
