modeling the global relationships among economic growth energy consumption and co2 emissions abstract the relationships among economic growth energy consumption and greenhouse gas emissions needs to be paid attention since the characteristics of global warming is from economy and greenhouse gas emissions this study employs a panel cointegration and vector error correction model to discuss the dynamic economy energy environment nexus for 188 countries for the periods of 1993 2010 the empirical results indicate that there exist long run relationships between economic growth energy consumption and carbon dioxide emissions for all countries it is worth noting that energy consumption negatively affects gdp in the world as a whole and developing countries but not in developed countries and the unidirectional causality from energy consumption to carbon dioxide emissions exists both on developing and developed countries that means the developed countries should take more responsibility on the energy efficiency and mitigating greenhouse gas emissions ghge on other hand environmental regulations related to the prevention of environmental degradation as the economy grows need to be adopted by all countries

estimating the public s value of implementing the co2 emissions trading scheme in korea abstract the korean government set out the carbon dioxide co2 emissions reduction target as 30 below business as usual by 2020 the co2 emissions trading scheme ets was initiated in january 2015 to meet this target we attempt to estimate the public s value of implementing the ets for co2 emissions reduction we apply the contingent valuation cv method using the willingness to pay wtp data obtained from a national cv survey of 1000 randomly selected households the survey was conducted via in person interviews value judgments required of the respondents were within their abilities the mean wtp to achieve the stated target of co2 emissions reduction using ets is estimated to be krw 1873 usd 1 66 per household per month which is statistically significant at the 1 level the aggregate national value amounts to krw 409 2 billion usd 363 4 million per year thus even though korea has no obligations to cut emissions under the kyoto protocol the public is willing to bear a financial burden to implement the ets if its cost is less than this value implementing the ets can be socially profitable the results of this study can serve as a basis for further policy discussions and decisions

economic feasibility of the path to zero net carbon emissions the united states and other developed countries currently and historically have transferred considerable resources overseas to further their foreign policy objectives and to purchase oil and natural gas these transfers are comparable in magnitude to estimates of the scale of the economic effort that would be required to create a world wide energy system with zero carbon emissions by the middle of this century solar energy the most abundant of the alternative energy supply sources is currently the most expensive of the alternatives to fossil fuels but a substantial body of research and practical experience suggests that solar costs could fall to competitive levels with sufficient technological progress and increases in solar energy production and capacity

sluggish intersectoral factor movements and alternative trade policies one of the basic assumptions of the standard two sector two factor general equilibrium model of production and trade is that factors are perfectly mobile between two sectors if a policy induced or policy independent change in a parameter of the model leads to an inequality in the price of a factor as between two sectors movement of the factor from the lower price sector to the higher price one will take place under the assumption of perfect mobility and that will eventually eliminate the intersectoral difference in factor prices at the new equilibrium this assumption of perfect mobility of factors has recently been a topic of further research in the two sector production and trade literature questions have been raised about the validity of this assumption see e g mussa 5 125 41 yu 7 387 93 casas 2 747 61 yu and parai 8 601 09 and parai and yu 6 842 52 in the context of labor it is argued that a policy induced increase in the wage rate in one sector does not necessarily lead to a movement of enough labor from the other sector so as to re establish the equality between sectoral wage rates even in the long run geographical or locational preferences of individuals for living in one area over another serious attachments of workers to one region due to strong family ties or high costs of moving from one place to another have usually been the reasons for the sluggish movement of labor from one sector to the other on the other hand the sluggishness in the mobility of physical capital is explained by the investors attitude towards uncertainty in other sectors and also the high cost of moving and adjusting to the need of the new industry given this imperfect mobility the net rental rates would not equalize between two sectors even in the long run mussa and casas separately modeled the imperfect labor mobility problem whereas grossman 3 1 17 modeled the case of imperfect capital mobility hill and mendez 4 19 25 however developed a general model incorporating the imperfect mobility of both capital and labor in the two sector general equilibrium model of production parai and yu have used the both factors are imperfectly mobile the purpose of the present paper is to extend the parai yu analysis further to investigate the implications of imperfect factor mobility in the analysis of standard gains from trade issues in the literature specifically we intend

the economy impacts of korean ets with an emphasis on sectoral coverage based on a cge approach abstract south korea initiated an emissions trading scheme ets on january 1 2015 based on this environmental policy at the 21st conference of parties cop meeting the korean government announced that it would decrease carbon emissions 37 from business as usual bau levels by 2030 since this target is too ambitious for the korean economy a number of studies have analyzed the economic impacts of emissions trading in korea but few have distinguished between industries covered and not covered by the ets notwithstanding the lack of industry level data on quotas and emissions this study overcomes such shortcomings by converting a dataset of 525 firms covered by the south korea ets sk ets into a 28 sector database consistent with the global trade analysis project gtap classifications we implement a simulation of the sk ets with a computational general equilibrium cge model simulation results suggest that while sk ets has significant abatement effects 2 56 from the base case it only has mild negative impacts on gdp 0 41 and household consumption 0 11 industry output on average falls by 0 54 with the gas and air transport sectors most adversely affected the most noticeable price changes are from the electricity sector whose output price goes up by 3 75 it is noteworthy that because of the export oriented economy many global business leaders and politicians have argued that the ets will disadvantage exporting companies while the simulation results showed a higher trade surplus based on enhanced competitiveness

on the causal dynamics between emissions nuclear energy renewable energy and economic growth this paper examines the causal relationship between co2 emissions nuclear energy consumption renewable energy consumption and economic growth for a group of 19 developed and developing countries for the period 1984 2007 using a panel error correction model the long run estimates indicate that there is a statistically significant negative association between nuclear energy consumption and emissions but a statistically significant positive relationship between emissions and renewable energy consumption the results from the panel granger causality tests suggest that in the short run nuclear energy consumption plays an important role in reducing co2 emissions whereas renewable energy consumption does not contribute to reductions in emissions this may be due to the lack of adequate storage technology to overcome intermittent supply problems as a result electricity producers have to rely on emission generating energy sources to meet peak load demand

should renewable energy policy be renewable political flexibility brings about trade offs for policy makers aiming to support the deployment of renewable energy sources res on the one hand it allows incorporating new information on ex ante uncertain benefits and costs of res policy on the other hand it may deter res investments this paper scrutinizes how these trade offs play out economically and politically when res policy makers choose the degree of flexibility as well as the instruments to implement flexibility the analysis builds on a theoretical framework distinguishing between flexibility by design and by adjustment it is complemented by a discussion of three case studies res support schemes in germany and the united kingdom and the eu emissions trading scheme theoretical as well as empirical results suggest that the politically chosen degree of flexibility by policy design may be sub optimally low in contrast flexibility by policy adjustment is often excessively high

who should abate carbon emission we review the optimal pattern of carbon emission abatements across countries in a simple multi country world we model explicitly with the model in chichilnisky 4 the fact that the atmosphere is a public good within this framework we establish conditions for it to be necessary for optimality that the marginal cost of abatement be the same in all countries these condition are quite restrictive and amount to either ignoring distributional issues between countries or operating within a framework within which lump sum transfers can be made between countries these results have implications for the use of tradeable emission permits which as normally advocated will lead to the equalization of marginal abatement costs across countries the observation that the atmosphere is a public good implies that we may need to look at a lindahl equilibrium rather than a walrasian equilibrium in tradeable permits

synergetic effects of water and climate policy on energy water nexus in china a computable general equilibrium analysis abstract a unified policy framework for energy and water would be beneficial considering the high interdependence of the two resources in china in this paper a recursive dynamic computable general equilibrium model is established to examine the existence of synergetic effects within water fee policy and energy related climate policy i e carbon tax and provide insights for chinese integrative policy making the results show that water fee can contribute to industrial water conservation whereas its effect is limited under current water fee level the adoption of a carbon tax in addition to it might further improve its water saving benefits furthermore water fee can also promote the enhancement of china s emission reduction goal and a higher carbon tax and water fee rate can achieve greater emission reduction effects at this point the synergetic spillover effects that water conservation benefits will be achieved simultaneously via the transition of industry into a more low carbon form is critical for elaborating an effective strategy of environmental policy besides our results suggest that giving priority to renewable power is regarded as the silver bullet to address the water and emission constraints on energy system as it can optimize the water conservation benefits of emission reduction

magnitude and direction of technological transfers for mitigating ghg emissions this paper discusses the issues of technological transfers aimed at reducing ghg mitigation costs under various assumptions in a new version of rice model we introduce technological transfer mechanism that donors monetary transfers go to recipients ghg mitigation through such transfer mechanism we examine the relationships between magnitude direction of transfers and choice of social welfare weights in the model our simulations show that different social welfare weights may lead to significant shifts on magnitudes even directions of technological transfers the results suggest that proposing policies of technological transfers should be mindful of distributional aspects and modeling assumptions

how to decide when experts disagree uncertainty based choice rules in environmental policy environmental economists have traditionally addressed the issue of choice under uncertainty by applying the expected utility hypothesis when policymakers face a panel of experts with widely divergent beliefs the problem may more accurately be described as a case of choice under pure uncertainty arrow and hurwicz 1972 demonstrate that rational choice criteria under pure uncertainty will focus on the extremes of the state space not the midpoint as is typically assumed using nordhaus s dice model uncertainty based choices about global warming policies are evaluated linkages to the safe minimum standard and the precautionary principle are also discussed

carbon dioxide emissions allocation a review carbon dioxide co2 emissions allocation plays a fundamental role in determining reduction responsibility at economy level or emission permits at firm level past decades have seen the development and applications of various methods for co2 emissions allocation this paper provides a literature review of co2 emissions allocation with emphasis on the evolution of allocation methods used it begins with a summary of the most popular allocation principles and criteria that lay a foundation for the development of allocation methods we then classify the existing allocation methods into four groups namely indicator optimization game theoretic and hybrid approaches the main features and findings of past studies are identified and summarized while the fairness principle prevails in earlier studies the efficiency principle has been found to receive increasing attention recently we also present a comparison of the empirical results based on ten popular indicator methods to show how indicator choice affects the allocation results issues related to selecting appropriate methods in co2 emissions allocation are finally discussed further research may be carried out to strike a balance between fairness and efficiency so that the allocation results become more widely acceptable and economically feasible

the political economy of global carbon emissions reductions abstract the discussion about what reductions in greenhouse gas emissions are required and how the emissions rights might be distributed globally has fostered the belief that there is a fundamental conflict between the rich nations of the north and the poor but populous nations of the south the argument is that grandfathering the rights will only reinforce existing global inequalities while per capita distribution of the rights would lead to such huge transfers of wealth to the south as to be unacceptable to the north however a very simple general equilibrium model highlighting key elements of the global economy shows that this perception is incorrect under a plausible interpretation of the goal of the united nations framework convention on climate change to avoid dangerous anthropogenic interference with the climate system instead of using an economic damage function to determine the optimal level of emissions reductions the model s utility functions are calibrated to reflect scientific understanding of what would be required to stabilize the atmosphere at safe concentrations of greenhouse gases among policy options that would accomplish this the united states has a preference for grandfathering the allocation of emissions rights over a per capita allocation but this preference is not strong and could be offset by other geopolitical considerations

carbon emissions trading scheme exploration in china a multi agent based model abstract to develop a low carbon economy china launched seven pilot programs for carbon emissions trading cet in 2011 and plans to establish a nationwide cet mechanism in 2015 this paper formulated a multi agent based model to investigate the impacts of different cet designs in order to find the most appropriate one for china the proposed bottom up model includes all main economic agents in a general equilibrium framework the simulation results indicate that 1 cet would effectively reduce carbon emissions with a certain negative impact on the economy 2 as for allowance allocation the grandfathering rule is relatively moderate while the benchmarking rule is more aggressive 3 as for the carbon price when the price level in the secondary cet market is regulated to be around rmb 40 per metric ton a satisfactory emission mitigation effect can be obtained 4 the penalty rate is suggested to be carefully designed to balance the economy development and mitigation effect and 5 subsidy policy for energy technology improvement can effectively reduce carbon emissions without an additional negative impact on the economy the results also indicate that the proposed novel model is a promising tool for cet policy making and analyses

does ecological economics have a future contradiction and reinvention in the age of climate change abstract this paper addresses the role of neoclassical methodologies in ecological economics and the contradictions these methodologies pose to the field s critical founding principles we first consider robert costanza s treatment of nicholas stern s global deal and then survey climate change related articles published in this journal over the past five years this survey reveals how mainstream neoclassical methodologies dominate discourse and do so by marginalizing more critical political economy analyses this situation imperils the field s founding vision of a no growth steady state it also fails to address the related growth dynamics of capitalism without such a critical treatment the field s formal embrace of methodological pluralism actually entails an ideological empiricism that renders ecological economics theoretically incoherent this situation undermines the field s historical promise as an alternative economic paradigm ecological economics now faces a problematic future its survival in a form faithful to its founding vision will require an explicit choice to address its internal contradictions and reinvent itself in ways relevant to our contemporary context without such a choice ecological economics will likely succumb to an implicit acceptance of the hegemony of mainstream economic methodologies and their pro growth imperatives

coupling model of energy consumption with changes in environmental utility abstract this study explores the relationships between metropolis energy consumption and environmental utility changes by a proposed environmental utility of energy consumption euec model based on the dynamic equilibrium of input output economics theory it considers three simulation scenarios fixed technology technological innovation and green building effect it is applied to analyse hong kong in 1980 2007 continual increase in energy consumption with rapid economic growth degraded environmental utility first energy consumption at fixed technology was determined by economic outcome in 1990 it reached a critical balanced state when energy consumption was 22 109 kwh before 1990 x1 22 109 kwh expansion of energy consumption facilitated socio economic development but suppressed environmental benefits second technological innovation strongly influenced energy demand and improved environmental benefits the balanced state remained in 1999 when energy consumption reached 32 33 109 kwh technological innovation dampened energy consumption by 12 99 exceeding the fixed technology condition finally green buildings reduced energy consumption by an average of 17 5 in 1990 2007 they contributed significantly to energy saving and buffered temperature fluctuations between external and internal environment the case investigations verified the efficiency of the euec model which can effectively evaluate the interplay of energy consumption and environmental quality

irreversible abatement investment under cost uncertainties tradable emission permits and emissions charges abstract a major concern with tradable emission permits is that stochastic permit prices may reduce a firm s incentive to invest in abatement capital or technologies relative to other policies such as a fixed emissions charge however under efficient permit trading the permit price uncertainty is caused by abatement cost uncertainties which affect investment under both permit and charge policies we develop a rational expectations general equilibrium model of permit trading and irreversible abatement investment to show how cost uncertainties affect investment under permits we compare the resulting investment incentive with that under charges after controlling for the assumption that random shocks affect the abatement cost linearly we find that firms investment incentive decreases in cost uncertainties but more so under emissions charges than under permits therefore tradable permits in fact may help maintain firms investment incentive under uncertainty

potential cost savings from internal external co2 emissions trading in the korean electric power industry abstract korea plans to introduce an emissions trading scheme for the controlling greenhouse gas emissions in 2015 using shephard s 1970 output distance function we first estimate the shadow price of co 2 for power generators in the korean fossil fueled electric generation industry then by assuming that each power generator is required to reduce co 2 emissions by one ton we compute the potential cost savings from internal trading among generators within the same plant and from external trading across plants at prevailing market prices the results indicate that on average the generators paid 14 63 to abate one ton of co 2 emissions in 2007 plants realized additional gains through external trading in particular cost savings from trades between different fuel fired plants were substantial

on modeling and interpreting the economics of catastrophic climate change with climate change as prototype example this paper analyzes the implications of structural uncertainty for the economics of low probability high impact catastrophes even when updated by bayesian learning uncertain structural parameters induce a critical tail fattening of posterior predictive distributions such fattened tails have strong im plications for situations like climate change where a catastrophe is theoretically possible because prior knowledge cannot place sufficiently narrow bounds on overall damages this paper shows that the economic consequences of fat tailed structural uncertainty along with unsureness about high temperature damages can readily outweigh the effects of discounting in climate change policy analysis

imperfect factor mobility a generalization and synthesis of two sector models of international trade the paper constructs and analyses a two sector model characterized by an endogenous factor price differential resulting from imperfect factor mobility it is shown that various models commonly used in international trade theory are special cases of our model the major conclusions include 1 a demonstration that commodity factor intensity rankings do not alone determine the relationship between endogenous and exogenous variables 2 an indication of the role played by the elasticity of intersectoral factor mobility in determining the effects of exogenous disturbances and 3 a proof that the allocational and distributional effects of factor price differentials must be dissociated from their welfare implications mobiliue imparfaite desfacteurs de production synthese et gmneralisation des modcles a deux secteurs dans la theorie du commerce international ce memoire pr6sente et analyse un modele a deux secteurs caracterise par un differentiel endogene dans le prix des facteurs de production entre secteurs suscite par la mobilit6 imparfaite des facteurs de production on montre que les divers modeles utilises traditionnellement dans la theorie du commerce international sont des cas particuliers du modele presente ici les conclusions principales sont i que l ordonnancement des coefficients d intensite des facteurs pour les differents biens ne suffit pas pour definir le rapport entre les variables exogenes et endogenes ii une indication du role joue par l elasticite de la mobilite des facteurs entre secteurs dans la definition de l impact des chocs exogenes et iii une preuve que les effets d allocation et de repartition des differentiels de prix des facteurs entre secteurs peuvent etre dissocies de leur impact au plan du bien etre

factor immobility and gains from trade the implications of imperfect factor mobility have been studied by for example batra 1 ch 10 mussa 10 grossman 7 hill and mendez 8 and casas 4 among others this factorimmobility literature has generated many interesting results in the neo classical trade theory the issue of gains from trade has been studied by batra 1 ch 4 eaton and panagariya 6 choi and yu 5 and batra and naqvi 2 the implications of imperfect factor mobility for gains from trade remain by and large unexplored the main purpose of this paper is to explore the implications of factor immobility for several gains from trade and optimal policy issues a special feature of the present paper involves an endogenously determined wage differential arising from factor immobility however the wage distortion is not a genuine distortion as the social welfare depends upon workers locational preferences in addition to consumer demands the paper is developed as follows section ii describes the model and its assumptions section iii presents the analysis regarding the optimality of free trade free trade vs no trade and the optimal policies section iv shows the welfare effects of protection measures section v offers the concluding remarks

who should abate carbon emissions an international viewpoint abstract we review the optimal pattern of carbon emission abatements across countries in a simple multi country world we model explicitly with the model in chichilnisky 1993b the fact that the atmosphere is a public good within this framework we establish conditions for it to be necessary for optimality that the marginal cost of abatement be the same in all countries these conditions are quite restrictive and amount to either ignoring distributional issues between countries or operating within a framework within which lump sum transfers can be made between countries these results have implications for the use of tradeable emission permits which as normally advocated will lead to the equalization of marginal abatement costs across countries the observation that the atmosphere is a public good implies that we may need to look at a lindahl equilibrium rather than a walrasian equilibrium in tradeable permits

what role of renewable and non renewable electricity consumption and output is needed to initially mitigate co2 emissions in mena region abstract this study attempts to explore the causal relationship between renewable and non renewable electricity consumption output and carbon dioxide co 2 emissions for 10 middle east and north africa mena countries over the period of 1980 2009 the results from panel fully modified ordinary least squares fmols and dynamic ordinary least squares dols show that renewable and non renewable electricity consumption add in co 2 emissions while output real gross domestic product gdp per capita exhibits an inverted u shaped relationship with co 2 emissions i e the environment kuznets curve ekc hypothesis is validated the short run dynamics indicate the unidirectional causality running from renewable and non renewable electricity consumption and output to co 2 emissions in the long run there appears to be a bidirectional causality between electricity consumption renewable and non renewable and co 2 emissions the findings suggest that future reductions in co 2 emissions might be achieved at the cost of economic growth

a review of the stern review on the economics of climate change the stern review calls for immediate decisive action to stabilize greenhouse gases because the benefits of strong early action on climate change outweighs the costs the economic analysis supporting this conclusion consists mostly of two basic strands the first strand is a formal aggregative model that relies for its conclusions primari ly upon imposing a very low discount rate concerning this discount rate aspect i am skeptical of the review s formal analysis but this essay points out that we are actual ly a lot less sure about what interest rate should be used for discounting climate change than is commonly acknowledged the review s second basic strand is a more intuitive argument that it might be very important to avoid possibly large uncertain ties that are difficult to quantify concerning this uncertainty aspect i argue that it might be recast into sound analytical reasoning that might justify some of the review s conclusions the basic issue here is that spending money to slow global warming should perhaps not be conceptualized primarily as being about consump tion smoothing as much as being about how much insurance to buy to offset the small change of a ruinous catastrophe that is difficult to compensate by ordinary savings

who should abate carbon emissions a note economists commonly believe that failure to equalize the marginal cost of carbon abatement across countries implies a loss of global efficiency chichilnisky and heal 1994 economic letters 44 444 first challenged this consensus a decade ago demonstrating that in general efficiency does not require equalizing marginal abatement costs this note revisits that important debate it provides the missing intuition behind chichilnisky and heal s surprising result explains what critical assumption gives rise to their result and clarifies the role a social welfare function plays in their model the implications of chichilnisky and heal s result are increasingly important given international debate over the preferential role given to developing countries in the kyoto protocol and the role those countries will play in future climate negotiations

the impact on electric power industry under the implementation of national carbon trading market in china a dynamic cge analysis abstract as the largest carbon emissions source sector electric power industry is undoubtedly a principal part of the carbon trading market in china aimed at researching the impact on power industry beyond establishing the national carbon trading market a dynamic computable general equilibrium cge model embedded with carbon trading block is introduced in this paper subsequently we design 8 scenarios of which illustrate corresponding industry carbon emissions baselines and free quotas ratios the main simulation results are as follows the implementation of carbon emissions trading would bring a certain negative impact on the overall economy real gdp will be reduced by about 0 08 0 52 in 2030 though low free quotas ratio will cause a relatively high loss of gdp this negative impact would be eliminated in the long run in addition carbon emissions trading would also promote the clean production of electricity indeed the electric power industry would reach carbon emissions peak around 2020 relative to scenarios without carbon trading carbon emissions would reduce more than 1000 million tons in 2030 when industry carbon emissions baseline declines at an annual rate of 2 consequently the carbon market can achieve a more significant reduction in carbon emissions with the influencing of quotas fully auctioned scenario

factor mobility and the general equilibrium model of production abstract the two sector production model is generalized to accommodate any degree of mobility in the two factors the model provides a convenient framework for exploring the manner in which factor mobilities interact with factor intensities in resolving a number of basic issues in neoclassical trade theory particular emphasis is placed on determining the importance of absolute mobility when the two factors are equally mobile and of the size of the mobility differential when factor intensities are equal across sectors

growth and energy nexus in europe revisited evidence from a fixed effects political economy model this is an empirical study on the causal relationship between economic growth and energy for 26 european countries in a multivariate panel framework over the period 1975 2009 using a two way fixed effects model and including greenhouse gas emissions capital fossil energy consumption herfindahl index political competition and number of years the government chief executive stays in office political stability as independent variables in the model empirical results confirm bidirectional causality between growth and political stability capital and political stability capital and fossil energy consumption whether political stability favors the implementation of growth or leads to corruption demands further research

governance of co2 markets lessons from the eu ets the european emissions trading scheme eu ets is the centerpiece of europe s climate policy the system has been undermined variously by the weakness of its regulation an undesirable overlap with other public policies and the far reaching economic and financial crisis that caused the market price of allowances to plunge this article attempts to identify the conditions for making the coming years of the eu ets a success it draws historical lessons from the eight years the scheme has been in operation and then presents the various interventions by the public authorities currently under discussion in order to revive the market finally the article proposes to draw lessons from monetary policy by outlining what might be the mandate of an independent carbon market authority with responsibility for the dynamic management of the supply of allowances and whose main mission would be to ensure the optimal linkage between the different temporal horizons of the climate strategy this article could provide important lessons for schemes developing in the rest of the world especially in south korea or in china

carbon markets 15 years after kyoto lessons learned new challenges abstract carbon markets are substantial and they are expanding there are many lessons from market experiences over the past eight years there should be fewer free allowances better management of market sensitive information and a recognition that trading systems require adjustments that have consequences for market participants and market confidence moreover the emerging market architecture features separate emissions trading systems serving distinct jurisdictions and a variety of other types of policies exist alongside the carbon markets this situation is in sharp contrast to the top down integrated global trading architecture envisioned 15 years ago by the designers of the kyoto protocol and raises a suite of new questions in this new architecture jurisdictions with emissions trading have to decide how whether and when to link with one another stakeholders and policymakers must confront how to measure the comparability of efforts among markets as well as relative to a variety of other polic

imperfect factor mobility and the distribution of income abstract when labor is imperfectly mobile between industries workers may have a special interest in commercial policies that increase the price of the output of the industry in which they are employed this proposition is investigated in a two good model in which the degree of labor mobility is measured by the elasticity of a convex input transformation curve the existence of such a transformation curve is justified by a model in which individual workers have differing relative and absolute efficiencies in different industries the results are extended to the case of many industries

time and frequency connectedness among oil shocks electricity and clean energy markets abstract this paper examines the time and frequency connectedness among electricity carbon and clean energy markets and oil price demand and supply shocks in doing so we use the spillover method proposed by diebold and yilmaz 2012 and its extension in the frequency domain by barunik and k ehlik 2018 we find increased connectedness during the global financial crisis as well as in the shale oil revolution period the total connectedness is also higher in the short run compared to the long run due to their low connectedness electricity futures can act as a risk diversifier and safe haven asset against oil shocks net pairwise directional connectedness among oil shocks and the clean energy index is higher during the shale oil revolution these results have important implications for investors with different investment time horizons

does improved environmental quality prevent a growing economy abstract a major concern for sustainable development is how countries can lower pollution while avoiding adverse output and energy shocks since economic activities change with time we develop a dynamic applied equilibrium model to study the dynamics of co2 emissions and evaluate how the pursuit of environmental policy objectives can influence output and productivity in a surrogate country in transition under an optimal environmental policy which ensures mitigation between 38 and 50 we show that productivity projected towards the year 2075 increases slightly from between 3 8 and 6 2 to between 5 7 and 7 6 respectively the required carbon tax begins from 5 29 ton in 2020 and grows on average by 3 5 reaching up to 35 83 per ton carbon towards the year 2075 even though these tax rates ensure huge benefits for mitigation they represent marginal productivity growth and substantial output and consumption costs in other words improved environmental quality presents opportunities for multifactor productivity mfp but this productivity improvement is too marginal to offset the compliance costs of the carbon tax thereby causing output to decline hence to ensure maximum economic dividend from carbon pricing especially in transitional economies measures are required to improve the innovation benefits of carbon taxes towards levels that offset the compliance costs of environmental regulations otherwise caution should be taken by developing countries in their environmental policy designs especially when boosting consumption and economic growth is a major priority

impacts and implications of implementing voluntary greenhouse gas emission reduction targets in major countries and korea abstract this study analyses the pledges submitted by korea and other major parties to the unfccc secretariat as part of the copenhagen accord using the global cge model the analysis shows that the greenhouse gas ghg emissions of the developed countries decrease by up to 14 0 by 2020 compared to the 1990 level these results show the need to raise the targets amongst developed countries in order to reach to the reduction levels 25 40 recommended by the ipcc to meet 450 ppm co2 eq on the other hand the full implementation of those pledges of annex i and non annex i countries was found to contribute to the decrease of the global ghg emissions by about 15 9 compared to business as usual bau such results imply the need for developed countries to step up their reduction targets as well as for developing ones to participate comprehensively and to reduce ghg emissions at a considerable level in order to enhance the environmental effectiveness of the post kyoto framework hereafter meanwhile it is analyzed that the implementation of voluntary target among major countries would reduce the global real gdp by 1 2 and in the case of korea the real gdp was projected to diminish by 1 5

the environmental and economic impact of the emissions trading scheme ets in vietnam abstract this study aims to fill a gap in the literature by examining the impacts of an emissions trading scheme ets in vietnam as the policy has been discussed for a decade in the country but the likely impacts on the economy and different sectors are still unidentified the simulations are carried out in a global energy computable general equilibrium cge model an extension of the gtap e model which treats vietnam as a country region results show that restricting the number of industrial sectors in the emissions trading market substantially affects the country s economy with a decline in real gdp by 4 57 however the country experiences much smaller adverse impacts e g real gdp declines by 1 78 when all industries participate in the emissions trading market in either case of the ets design the coal mining manufacturing transportation and electricity sectors are highly adversely affected however the crude oil and natural gas extraction sectors would experience expansion in their production levels due to substitutions for coal in general under the policy the emission levels from burning fossil fuels decline at significant rates particularly from the electricity generation sector

evaluating the interplays among economic growth and energy consumption and co2 emission of china during 1990 2007 the interplays among economy and energy and environment have been widely concerned this paper put forward several indicators to quantify the relationships among economic growth and energy consumption and co2 emission as an example these indicators were applied to evaluate the comprehensive performances of china during 1990 2007 the results show that chinese people has been living a better life with chinese rapid economic growth but not synchronously in urban and rural areas non carbon energy resources share has increased however fossil energy resources have still acted as the main driver for chinese economic growth during this period technical progress has improved the fossil energy efficiency of chinese economic activity which leads to co2 emission per unit gdp and co2 emission per capita unit gdp dropping simultaneously however the two indicators annual decline rates become smaller and smaller which reflects that technical progress role is dropping and economic scale s effect is climbing people s survival has a rising contribution to co2 emission co2 emission per capita has increased which shows that economic scale has greater impact on co2 emission than technical progress does relatively speaking chinese development patterns have become more and more sustainable during this period finally based on the related issues being discussed some corresponding suggestions are put forward for chinese government to further coordinate the relationship among economic development and energy consumption and co2 emission the proposed indicators can form a set of useful tool for policy makers to promote the harmonious development of economy and energy and environment in different regions and countries

a regional dynamic general equilibrium model of alternative climate change strategies outcomes and noncooperative equilibria this study finds that cooperative policies show much higher levels of emissions reductions than do noncooperative strategies that there are substantial differences in the levels of controls in both the cooperative and the noncooperative policies among different countries and that high income countries may be the major losers from cooperation jel h41 q4 q2 q20

integrating economic analysis and the science of climate instability abstract scientific understanding of climate change and climate instability has undergone a revolution in the past decade with the discovery of numerous past climate transitions so rapid and so unlike the expectation of smooth climate changes that they would have previously been unbelievable to the scientific community models commonly used by economists to assess the wisdom of adapting to human induced climate change rather than averting it lack the ability to incorporate this new scientific knowledge here we identify and explain the nature of recent scientific advances and describe the key ways in which failure to reflect new knowledge in economic analysis skews the results of that analysis this includes the understanding that economic optimization models reliant on convexity are inherently unable to determine an optimal policy solution it is incumbent on economists to understand and to incorporate the new science in their models and on climatologists and other scientists to understand the basis of economic models so that they can assist in this essential effort

efficiency wages disinflation and labor mobility abstract the paper analyzes the role of labor market segmentation and relative wage rigidity in the transmission process of disinflation policies in an open economy facing imperfect capital markets wages are flexible in the nontradables sector and based on efficiency factors in the tradables sector with perfect labor mobility a permanent reduction in the devaluation rate leads in the long run to a real appreciation a lower ratio of output of tradables to nontradables an increase in real wages measured in terms of tradables and a fall in the product wage in the nontradables sector under imperfect labor mobility unemployment temporarily rises
