is the long run relationship between economic growth electricity consumption carbon dioxide emissions and financial development in gulf cooperation council countries robust the relationship between carbon dioxide emissions economic growth electricity consumption and financial development in the gulf cooperation council gcc countries is investigated in this study using panel data for the period of 1980 2012 a number of econometric techniques dynamic ordinary least squares dols fully modified ordinary least squares fmols and the dynamic fixed effect model dfe are applied in order to estimate the long run relationship between the variables the long run relationship is found to be robust across these different econometric specifications no significant short run significant relationship was observed electricity consumption and economic growth have a positive long run relationship with carbon dioxide co2 emissions whilst a negative and significant relationship was found between co2 emissions and financial development the findings imply that electricity consumption and economic growth stimulate co2 emissions in gcc countries while financial development reduces it granger causality results reveal that there is a bidirectional causal link between economic growth and co2 emissions and a unidirectional causal link running from electricity consumption to co2 emissions however there is no causal link between financial development and co2 emissions also impulse response and variance decomposition analysis outline forecasted impacts of economic growth and electricity consumption on future co2 emissions

firm incentives to promote technological change in pollution control reply abstract the process of technological change in pollution control is broken into three basic steps innovation diffusion and optimal agency response firm incentives to promote these steps are then examined under five regulatory regimes direct controls emission subsidies emission taxes free marketable permits and auctioned marketable permits on a relative basis emission taxes and auctioned permits provide the highest firm incentives to promote technological change at times free permits generate lower incentives direct controls which are common regulatory tools usually provide the lowest relative firm incentives to promote technological change

economic growth and transport energy consumption in the latin american and caribbean countries abstract transport is a strategic sector for economic development whilst being one of the most polluting sectors of the economy the latin american and caribbean countries have been consolidated as the region with significantly faster energy consumption growth this paper analyzes how the gdp per capita affects the transport energy consumption testing possible non linear relationships between variables a transport energy consumption function depending on gdp and its squared and cubed value is estimated for 22 lac countries over the period 1990 2014 the results support an n shaped curve while the elasticity values of transport energy consumption with respect to gdp per capita do not show a tendency to decrease in the long term fourteen lac countries show absolute coupling levels at the end of the period while the rest exhibit partial couplings likewise trade openness population density degree of urbanization and structural changes in the economy have positive effects on the transport energy consumption this paper proposes some energy efficiency measures to control the growing energy use and the promotion of biofuels and electric vehicles is also considered necessary to reduce the negative effects of transport energy use

strategic response to pollution taxes in supply chain networks dynamic spatial and organizational dimensions abstract this paper presents a model of the strategic behavior of firms operating in a spatial supply chain network the manufacturing and retailing firms engage in an oligopolistic noncooperative game by sharing customer demand such that a firm s decisions impact the product prices which in turn result in changes in all other firms decisions each firm s payoff is to maximize its own profit and we show that in response to such changes in prices and to exogenous environmental taxes the manufacturing firms may strategically alter a variety of choices such as make buy decisions with respect to intermediate inputs spatial distribution of production product shipment patterns and inventory management environmental tax payment vs recycling decisions and timing of all such choices to sustainably manage the profit and the environmental regulations an important implication is that effects of a tax depends on the oligopolistic game structure with respect to methods we show that this dynamic game can be represented as a set of differential variational inequalities dvis that motivate a computationally efficient nonlinear complementarity ncp approach that enables the full exploitation of above mentioned salient features we also provide a numerical example that confirms the utility of our proposed framework and shows substantial strategic reaction can be expected to a tax on pollution stocks

optimal pricing and advertising in a durable good duopoly abstract this paper analyzes dynamic advertising and pricing policies in a durable good duopoly the proposed infinite horizon model while general enough to capture dynamic price and advertising interactions in a competitive setting also permits closed form solutions we use differential game theory to analyze two different demand specifications linear demand and isoelastic demand for symmetric and asymmetric competitors we find that the optimal price is constant and does not vary with cumulative sales while the optimal advertising is decreasing with cumulative sales comparative statics for the results are presented

revenue sharing in airline alliances we propose a two stage game theoretic approach to study the operations of an airline alliance in which independent carriers managing different reservation and information systems can collaboratively market and operate codeshare and interline itineraries in the first stage game airlines negotiate fixed proration rates to share the revenues generated by such itineraries in the second stage game airlines operate independent inventory control systems to maximize their own expected revenues we derive a revenue sharing rule that is i an admissible outcome of the first stage negotiation in the sense that no airline coalition has enough incentives to secede from the grand alliance and ii efficient for the second stage game in the sense that the decentralized system can achieve the same revenues as a central planner managing the global alliance network our numerical study shows that the proposed proration rates can lead to a significant increase in revenues with respect to other rules commonly used

fuel consumption in road transport a comparative study of china and oecd countries abstract energy conservation and emissions reduction have been the focus of the road transport sector due to its energy intensive and air pollution intensive nature it also embodies the imprints of human technological progress this paper compares the energy consumption of the road transport sector in china and oecd countries we used time series and panel data co integration analysis error correction model and dynamic model to study the impacts of the major influencing factors such as income income structure urbanization price and technological advancement on gasoline and diesel consumption in road transport overall china s fuel consumption is influenced mainly by investment government expenditure and demographic changes such as urbanization while the fuel consumption of oecd countries is mainly driven by household final consumption expenditure in the short run and from a dynamic perspective china s fuel consumption is less influenced by its historical consumption than current influencing factors while that of oecd countries is more affected by historical fuel consumption based on the analysis and findings of this study some policy implications are proposed

art market inefficiency art is often used as an investment vehicle given the importance of market efficiency in finance we use a large auction based index to test whether the art market is weakly efficient evidence reveals that returns on artworks exhibit high positive auto correlation we attribute this result to price truncation resulting from unobservable reserve prices in auctions we conclude that the art market is not efficient mainly because price formation is opaque to outsiders who lack information on unsold artworks

how did japanese investments influence international art prices we test the luxury consumption hypothesis of ait sahalia parker and yogo 2004 using a unique international art price import export flow and stock market data set we find that the demand for art by japanese collectors is positively correlated with art prices and japanese stock prices this correlation is magnified during the bubble period of the japanese economy the mid 1980s to the early 1990s and gains even further strength for works of art typically favored by japanese collectors our results suggest that japanese investors or japanese asset markets indeed affect international art prices especially during the bubble period and its aftermath

carbon capture and storage and transboundary pollution a differential game approach abstract we study the strategic behavior of two countries facing transboundary co2 pollution under a differential game setting in our model the reduction of co2 concentration occurs through the carbon capture and storage process rather than through the adoption of cleaner technologies furthermore we first provide the explicit short run dynamics for this dynamic game with symmetric open loop and a special markovian nash strategy then we compare these strategies at the games steady states and along some balanced growth paths our results show that if the initial level of co2 is relatively high state dependent emissions reductions can lead to higher overall environmental quality hence feedback strategy leads to less social waste

what triggers environmental management and innovation empirical evidence for germany abstract it is frequently hypothesized that environmental management systems emss may improve firms environmental innovation performance whether this hypothesis is true is as critical for environmental policy as questions pertaining to the relevant incentives for 1 a firm s voluntary adoption of an ems and 2 its environmental innovation behavior based on ample empirical evidence for german manufacturing this paper addresses the simultaneity of these issues on the basis of a recursive bivariate probit model that explores the hypothesis that a facility s decision on innovation activities is correlated with the decision on ems adoption our empirical results indicating that environmental innovation activities are not associated with ems implementation nor any other single policy instrument reflect the perceptions of the survey respondents and hence should be interpreted as correlations rather than causal relationships according to these perceptions innovation behavior seems to be mainly correlated with the stringency of environmental policy

pollution accumulation and abatement policy in a supply chain abstract this paper seeks to determine how the double marginalization phenomenon affects the tradeoff between polluting emissions and abatement activities related to pollution accumulation in a supply chain composed of one manufacturer and one retailer the environmental consequence of this inefficiency which emerges in a non cooperative vertical setting governed by a single parameter contract is overlooked in the literature on pollution control in the setup of a two stage game we investigate the impact of double marginalization for non cooperative equilibrium to check whether there are differences between dynamic and strategic effects of double marginalization on pollution accumulation both the open loop and feedback nash equilibria are derived over a finite time horizon with the cooperative solution as a benchmark

sentiment and art prices we hypothesize the existence of a slow moving fad component in art prices using unique panel survey data on art market participants confidence levels in the outlook for a set of artists we find that sentiment indeed predicts short term returns

emissions trading electricity restructuring and investment in pollution abatement this paper analyzes an emissions trading program that was introduced to reduce smog causing pollution from large stationary sources using variation in state level electricity industry restructuring activity i identify the effect of economic regulation on pollution permit market outcomes there are two main findings first deregulated plants in restructured electricity markets were less likely to adopt more capital intensive environmental compliance options as compared to regulated or publicly owned plants second as a consequence of heterogeneity in electricity market regulations a larger share of the permitted pollution is being emitted in states where air quality problems tend to be more severe jel l51 l94 l98 q53 q58 when the us federal government first began regulating major sources of air pollution in the 1960s the conventional approach to meeting air quality standards involved establishing maxi mum emissions rates or technology based standards for regulated stationary sources however economists have long maintained that an emissions permit market could more efficiently coor dinate pollution abatement activities provided a series of assumptions are met over the past few decades market based cap and trade cat approaches to regulating emissions from industrial point sources have become a centerpiece of environmental regulation in the united states in the theoretical first best permit market equilibrium the total social cost of meeting an emis sions cap is minimized each firm chooses a level of pollution abatement such that its marginal cost of reducing pollution is set equal to the social marginal benefit from emissions reduction in practice preexisting distortions in product markets that are subject to cat regulation may interfere with the emissions permit market s ability to operate efficiently this paper studies the effects of electricity market regulation on permit market outcomes in the context of a major us emissions trading program the nox budget program the recent wave of electricity industry restructuring in the united states has resulted in significant interstate variation in economic regulation consequently facilities in the same cat program face very different economic regu lation and investment incentives in their respective electricity markets whereas rate base regu lated plants are guaranteed to earn a rate of return on prudent investments in pollution abatement equipment deregulated plants operating in restructured electricity markets are offered no such

complex losses allocation to generators and loads based on circuit theory and aumann shapley method this paper presents a new method to allocate active and reactive losses simultaneously to generators and loads the allocation is calculated for each transmission branch identifying and quantifying the buses responsibilities in losses this is a two step process in the first step generators are modeled as current injections and loads as constant admittances in order to determine generator participations in losses in the second step loads are modeled as current sources and generators as constant admittances in order to determine load participations in losses the aumann shapley and circuit theories are used to calculate the participation of each real and imaginary current component considering them as independent players in the complex losses allocation game the properties of the aumann shapley method ensure equitable allocation and recovery of the total active and reactive losses counter flow cross subsidy and negative allocation issues are discussed numerical results are presented and discussed to demonstrate the applicability of the proposed method

a monopolistic and oligopolistic stochastic flow revenue management model this paper studies a one shot inventory replenishment problem with dynamic pricing the customer arrival rate is assumed to follow a geometric brownian motion homogeneous customers have an isoelastic demand function and do not behave strategically we find a closed form optimal pricing policy which utilizes current demand information under this pricing policy the inventory trajectory is deterministic and a retailer sells all inventory we show that dynamic pricing coordinated with the inventory decision achieves significantly higher profits than does static pricing furthermore under oligopolistic competition we establish a weak perfect bayesian equilibrium for the price and inventory replenishment game we find the pricing equilibrium to be cooperative even in a noncooperative environment but that inventory competition results in overstock and damages profits finally we examine the trade off between dynamic pricing and price precommitment and find that flexible pricing is still beneficial provided competition is not too intense

transmission loss unbundling and allocation under pool electricity markets this paper presents a methodology based on the circuit theories for unbundling and allocation of transmission losses among the participants of a pool based electricity market starting from a known operation point and using the basic network equations without additional assumptions an expression of the branch losses based on nodal current injections is derived since the power flow equations and circuit theories are satisfied the methodology turns explicit in a natural way separating the losses at each system branch and assigning the responsibility to the respective market participants it means that the loss allocation of each branch which is produced by each generator and consumer is obtained extensions and strategies considering unsubsidized and predefined proportion based loss allocation as well as issues related with the allocation fairness and transparency are also included comparisons with previous methods and validation tests of the proposed method are reported by using the ieee reliability test system

the impact of environmental management on firm performance environmental management has the potential to play a pivotal role in the financial performance of the firm many individuals suggest that profitability is hurt by the higher production costs of environmental management initiatives while others cite anecdotal evidence of increased profitability a theoretical model is proposed that links strong environmental management to improved perceived future financial performance as measured by stock market performance the linkage to firm performance is tested empirically using financial event methodology and archival data of firm level environmental and financial performance significant positive returns were measured for strong environmental management as indicated by environmental performance awards and significant negative returns were measured for weak environmental management as indicated by environmental crises the implicit financial market valuation of these events also was estimated cross sectional analysis of the environmental award events revealed differences for first time awards and between industries first time award announcements were associated with greater increases in market valuation although smaller increases were observed for firms in environmentally dirty industries possibly indicative of market skepticism this linkage between environmental management and financial performance can be used by both researchers and practitioners as one measure of the benefits experienced by industry leaders and as one criterion against which to measure investment alternatives

emission path planning based on dynamic abatement cost curve abstract global climate change is one of the most serious environmental problems that has attracted an unprecedented global attention the scientific community has recognized that human activity is mostly responsible for global climate warming therefore states participating in the united nations framework convention on climate change unfccc have initiated a series of negotiations on how to develop their own emission reduction targets however the realization of these targets is at the expense of economic development to a great extent therefore an abatement plan is necessary to decide how and when to implement emission reduction targets a marginal abatement cost curve macc often used as an important quantitative tool to estimate abatement burden or evaluate abatement performance should be considered carefully in this paper we enrich the traditional macc by introducing the concept of an immediate unit marginal abatement cost to describe its intrinsic incremental abatement difficulty this cost is proved to be agreed with the actual situation in many ways and is therefore very suitable for practical use two factor learning curve are considered in the model which can go some way in improving the performance of the revised macc using a parameterization method the original problem can be converted into a tractable nonlinear programming problem we use an algorithm to search for the approximate global optimal solution the effectiveness and the efficiency of the algorithm are discussed respectively in the results we find that the abatement path distinguishes largely under different abatement targets some plausible reasons and policy advices are given

investigating the validity of pollution haven hypothesis in the gulf cooperation council gcc countries this study investigated the validity of the pollution haven hypothesis in the gulf cooperation council gcc countries using a multivariate framework to achieve the goal of this study the non stationary panel techniques were used to examine the hypothesis from 1980 to 2009 based on the pedroni cointegration test results it was found that the variables are cointegrated moreover the fully modified ols results showed that energy consumption and gdp growth increase co2 emission while foreign direct investment inflows have a long run negative relationship with co2 emission furthermore based on the short run granger causality test results fdi has no short run causal relationship with co2 emission and energy consumption while energy consumption and gdp growth have a positive causal relationship with co2 emission thus the results of this study indicate that energy consumption and gdp growth are the source of pollution in the gcc countries and not the foreign direct investment inflows thus the study recommended that these countries should utilize policies to encourage inward foreign investment since it plays an important role in stimulating gdp growth

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

buying beauty on prices and returns in the art market this paper investigates the price determinants and investment performance of art we apply a hedonic regression analysis to a new data set of more than one million auction transactions of paintings and works on paper based on the resulting price index we conclude that art has appreciated in value by a moderate 3 97 per year in real u s dollar terms between 1957 and 2007 this is a performance similar to that of corporate bonds at much higher risk a repeat sales regression on a subset of the data demonstrates the robustness of our index next quantile regressions document larger average price appreciations and higher volatilities in more expensive price brackets we also find variation in historical returns across mediums and movements finally we show that measures of high income consumer confidence and art market sentiment predict art price trends this paper was accepted by wei xiong finance

emission permit banking pollution abatement and production inventory control of the firm abstract in this paper we present a dynamic model modified with emission permit banking and pollution abatement and investigate the effect of emission permit banking and pollution abatement on the production inventory strategy of the firm after introducing emission permit banking and pollution abatement the cost function consists of the inventory holding and production costs the cost of investment in abatement capital goods and the emission procurement selling cost furthermore the inventory holding costs are linear production costs are non decreasing and convex functions of the production level and the costs of investment in abatement capital goods are increasing and convex functions of the investment level we compare the optimal production inventory strategy before emission permit banking and pollution abatement and thereafter the mathematical investigation is based on the arrow karlin model

a weakly conditioned imputation of an impedance branch dissipation power in a sinusoidal steady state circuit how much of an impedance branch dissipation power should be assigned to each source the answer is the basis of electricity transmission pricing such as the pricing of line loss and line security due to thermal limit however it is difficult to obtain a unique and common consent answer because of the nonlinearity of power expression this paper presents two weakly conditioned imputation formulas respectively for dissipation active and reactive power to answer the question first a detailed form of shapley value formula and three weak conditions are proposed on this basis the two imputation formulas are then derived and proved mathematically the imputation formulas are explicitly in terms of source currents voltages thus analytic and easy to compute they possess eight mathematical and economic features that lay a good foundation for electricity transmission pricing the two imputation formulas are also extended to actual power systems where trades are conducted in mwh mvarh instead of amperes volts numerical examples illustrate their computing process and features

incentives for advanced pollution abatement technology at the industry level an evaluation of policy alternatives abstract in this research we evaluate the incentive effects of five environmental policy instruments to promote the development and adoption of advanced pollution abatement technology in a heterogenous industry from most to least incentive the policy instruments can be rank ordered as follows i auctioned permits ii emissions taxes and subsidies iii issued marketable permits iv performance standards including performance standards in this list necessitates the assumption that they are differentiated between heterogeneous firms before the technology adoption in a way which replicates the initial emissions control distribution of the efficient incentive based instruments with the starting point normalized in this fashion the instrument rankings are invariant with respect to the size of firms the size of the industry or the industry s abatement cost structure

does higher economic and financial development lead to environmental degradation evidence from bric countries abstract a vast number of studies addressed the environmental degradation and economic development but not financial development moreover as argued by stern 2004 the rise and fall of the environmental kuznets curve world development 32 1419 1439 they present important econometric weaknesses using standard reduced form modeling approach and controlling for country specific unobserved heterogeneity we investigate the linkage between not only economic development and environmental quality but also the financial development panel data over period 1992 2004 is used we find that both economic and financial development are determinants of the environmental quality in bric economies we show that higher degree of economic and financial development decreases the environmental degradation our analysis suggests that financial liberalization and openness are essential factors for the co 2 reduction the adoption of policies directed to financial openness and liberalization to attract higher levels of r d related foreign direct investment might reduce the environmental degradation in countries under consideration in addition the robustness check trough the inclusion of us and japan does not alter our main findings

energy consumption carbon emissions and economic growth in china abstract this paper investigates the existence and direction of granger causality between economic growth energy consumption and carbon emissions in china applying a multivariate model of economic growth energy use carbon emissions capital and urban population empirical results for china over the period 1960 2007 suggest a unidirectional granger causality running from gdp to energy consumption and a unidirectional granger causality running from energy consumption to carbon emissions in the long run evidence shows that neither carbon emissions nor energy consumption leads economic growth therefore the government of china can purse conservative energy policy and carbon emissions reduction policy in the long run without impeding economic growth

sectoral effects of a green tax reform in portugal abstract economic downturn coupled with serious and persisting environmental problems require a new regulation system to tackle these problems the portuguese government created the commission for the green tax reform in 2014 following the guidelines of the european union in the sense that fiscal policy should contribute to public budget consolidation and sustainable growth the commission was commissioned to propose a simplification of taxation in order to promote economic competitiveness environmental sustainability and the efficient use of resources the aim of this paper is to present the results from one of the teams that have contributed to the commission for the green tax reform we have followed the european commission guidelines in order to simulate a green tax reform with a static general equilibrium model and aligned to the political context we found that i it is possible to enjoy a positive double dividend ii to achieve improvements in the energy trade balance and energy independence and iii to reduce the energy intensity of the portuguese economy

on the partition of transmission losses among generators due to the introduction of competition in the electrical power industry determining the percentage of transmission grid losses that should be attributed to each generator has become important usually this is accomplished by determining the percentage of each transmission branch losses that should be attributed to each generator using the aumann shapley theory this letter identifies the fairest way to share the nonseparable portion of losses amongst the generators the obtained result validates some approximations assumed in recent papers and contributes to strengthening circuit theory based methods

competition in multiechelon assembly supply chains in this paper we study competition in multiechelon supply chains with an assembly structure firms in the supply chain are grouped into homogenous sectors nodes that contain identical firms with identical production capabilities that all produce exactly one undifferentiated product that may itself be a kit of components each sector may use several inputs to produce its product and these inputs are supplied by different sectors the production process within any sector is taken to be pure assembly in fixed proportions the number of firms in each sector is known the demand curve for the final product is assumed to be linear as are production costs in all sectors competition is modeled via a coordinated successive cournot model in which firms choose production quantities for their downstream market so as to maximize profits given prices for all inputs and all complementary products production quantities for sectors supplying the same successor are coordinated through pricing mechanisms so that complementary products are produced in the right proportions under these assumptions equilibrium prices for any multiechelon assembly network are characterized by a system of linear equations we derive closed form expressions for equilibrium quantities and prices in any two stage system i e a system with multiple input sectors and a single assembly sector we show that any assembly structure can be converted to an equivalent larger structure in which no more than two components are assembled at any node finally large structures can be solved either by direct solution of the characteristic linear equations or through an iterative reduction compression to smaller structures

transmission loss allocation i single energy market this paper presents a new methodology for allocating transmission losses to the participants of a single energy market the proposed approach is based on the incremental transmission loss concept and is implemented through two models basic and extended in the basic model the total system losses are estimated through the linear dc load flow equations while the extended model uses the exact ac formulation the concept of center of losses is used a fictitious bus in the system network where all transactions are compensated for transmission losses both models provide a sharing of transmission losses among generators and loads based on a predefined proportion for instance 50 50 for each participant class some important aspects related with the allocation fairness and transparency are illustrated by numerical applications with the ieee reliability test system the extension of this methodology to interconnected energy markets is treated in a companion paper

green growth planning a multi factor energy input output analysis of the canadian economy abstract incorporating socioeconomic and environmental considerations into energy decisions is necessary when tackling climate change and accelerating green growth in this work we propose a novel extension of the multi factor energy input output model to support evidence informed energy policy making and green growth planning through the introduction of eight different multipliers and two green growth indexes we demonstrate the approach through application at the national scale in canada in particular we quantitatively assess the extent to which changes in final demand impact the domestic and imported primary and renewable energy flows co2 emissions economic expansion and energy job earnings the results point to a potential path of green growth in canada prioritizing activities that generate economic and job growth at minimal environmental pressure i e fewer co2 emissions economic activities that are critical for stimulating green growth in the short to medium run are identified and recommendations are made regarding a longer structural change path for improving the supply chains of other economic activities this work provides insights to decision makers seeking strategies e g policy reforms or targeted public expenditure strategies to accelerate green growth planning on a national scale

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
