energy saving behavior and marginal abatement cost for household co2 emissions abstract this paper attempts to measure consumers perceived net benefits or net costs of energy saving measures in using energy consuming durable goods using the estimated net costs and the volume of co2 reduced by the measures a marginal abatement cost mac curve for the average household s co2 emissions is produced an analysis using the curve suggests that in order to provide households with an incentive to take actions that can lead to co2 emission reductions in using energy consuming durables a high level of carbon price is needed in addition a regression analysis reveals that the net benefits of the measures are larger for households that put a higher priority on energy saving for those living in detached houses for those with a smaller number of persons living together and for those with less income the result of the analysis using the mac curve may suggest that promoting energy saving behavior will require not only a policy to provide economic incentives but also interventions to influence psychological factors of household behavior

auctions with resale when private values are uncertain evidence from the lab and field abstract auction theory represents one of the richest areas of research in economics over the past three decades yet whether and to what extent the introduction of secondary resale markets influences bidding behavior in sealed bid first price auctions remains under researched this study begins by examining field data from a unique data set that includes nearly 3000 auctions over 10 000 individual bids for cutting rights of standing timber in british columbia from 1996 to 2000 in comparing bidding patterns across agents who are likely to have resale opportunities with those who likely do not we find evidence that is consistent with theory critical evaluation of the reduced form bidding model however reveals that sharp tests of the theoretical predictions are not possible because several other differences may exist across these bidder types we therefore use a laboratory experiment to examine if the resale opportunity by itself can have the predicted theoretical effect we find that while it does have the predicted effect a theoretical model based on risk averse bidders explains the overall data patterns more accurately than a model based on risk neutral bidders beyond testing theory the paper highlights the inferential power of combining naturally occurring data with laboratory data

a bibliometric analysis of research on carbon tax from 1989 to 2014 abstract as one of the most cost effective means of emission reduction carbon tax has attracted considerable attention from economists and international organizations and has led to a large number of related research using the bibliometric method this paper characterizes the carbon tax literature from 1989 to 2014 based on the network database platform of web of science the results indicate that the usa occupies a leading position in the carbon tax field the vrije university amsterdam massachusetts institute of technology and stanford university were the most productive research institutes energy policy 143 has been the most productive journal followed by energy economics 44 and energy 38 in general the cooperation of authors institutes and nations are continuing to strengthen however the growth rate at the author level was significantly higher than the others in addition the current key research areas in the carbon tax field based on co keyword analysis are as follows climate change and relevant policy carbon emissions trading socio economic effects of carbon tax renewable energy endogenous technological change and carbon capture and storage the results of this paper will help researchers grasp the current research in the carbon tax field but also provide a supporting role for future work

a random walk through mayfair art as a luxury good and evidence from dynamic models abstract the movement of international art prices in conjunction with other asset prices is preliminary to our understanding whether art is a luxury good it is well known that there are linkages between art market prices and equity prices however less is known about the structure of dependence between these variables and the influence of gold prices and sentiment we analyse art prices at the outset using granger causality and error correction models ecm to capture the long term dynamics between art prices equity markets gold prices and investor sentiment the dataset we use is unique and covers british art prices from 1895 to the present initial results do not give a complete picture of price movements or a fitting description of wealth effects to rectify this we look at short term dynamics in the art market we assume a regime switching model to describe the movement of prices using a threshold variable that drives prices into possibly locally explosive regimes these results indicate a dynamic wealth effect in that high low stock prices lead to subsequent increases decreases in art prices however this approach means that elasticities are now stochastic and we redefine what a luxury good is this is further explored by directly calculating elasticities from our model and its variants to analyse properties of art as a luxury good our threshold approach gives deeper insight into the impact of different market conditions than conventional ecm and cointegration modelling

a class of tractable incomplete market models for studying asset returns and risk exposure abstract we present a class of tractable incomplete market models where agents face both aggregate risk and limited participation in financial markets tractability relies on the assumptions of small asset volumes and of a period utility function that is linear beyond a threshold in line with fishburn s 1977 contribution in decision theory we prove the existence of an equilibrium and derive theoretical results regarding asset prices and consumption choices this small trade model is able to reproduce a low safe return and a high equity premium together with a realistic representation of household exposure to both idiosyncratic and aggregate risks

a derivation of the marginal abatement cost curve abstract the relationship between a firm s technology and its marginal abatement cost mac curve is explored even under the simplest specifications the mac curve will be kinked at some point except under a special assumption which in reality could easily be violated the nondifferentiability implies that the choice of instrument under uncertainty may depend on the targeted level of emissions reduction also stability conditions for dynamic tax mechanisms may be violated in the neighborhood of the kink point a policy implication is that in some cases output restrictions are as efficient as emissions restrictions in contrast to previous results

evaluation of land use based greenhouse gas abatement measures in germany abstract agricultural production contributes 11 to the total german greenhouse gas ghg emissions we compare the efficiency of three different land use based ghg abatement measures in combination and as separately applied measures the production of short rotation coppices of feedstocks for biomethane production and peatland restoration we evaluate these options with respect to the following criteria cost efficiency ghg abatement costs abatement potential and impact on agricultural production we use the regional supply model raumis to investigate the different abatement measures at the sector and regional level up to a reduction of ghg emission of 25 1012 g co2eq peatland restoration is the most cost efficient option short rotation coppice allow some cost efficient mitigation also only at limited scale energy maize is only an option if high abatement targets should be met the joint implementation of several abatement strategies allows meeting specified targets at lower costs the crowding out effect between the options is limited the spatial analysis indicates measure specific regional competitiveness and application e g short rotation coppice in eastern and southern germany peat restoration in northern germany and energy maize production in central germany

analysis of the economic impact of different chinese climate policy options based on a cge model incorporating endogenous technological change abatement cost is the main concern for climate change mitigation and the key factor for mitigation cost is technological change this study established an integrated economic energy environmental dynamic computable general equilibrium cge model representing endogenous technological change for china s climate change policy analysis this study analyzed and compared the economic impact of different approaches to mitigation commitments as well as the potential role of technological change in the formulation of mitigation targets and commitments taking into account china s climate policy making needs based on the current international climate negotiation process the results show that absolute emission limits similar to the kyoto protocol will seriously impede the future economic development of china while the impact of an 80 reduction in carbon intensity forecast for 2050 based on the 2005 level is relatively small technological change can promote economic growth improve energy efficiency and reduce carbon intensity per unit of output through the substitution of production factors consequently it can reduce marginal abatement cost and related gdp loss by mitigation at the same time it can increase mitigation potentials and extend the emission reduction amount showing that consideration of the impact of technological change when deciding the emission reduction targets is necessary

contractual responses to the common pool prorationing of crude oil production this paper examines bargaining among firms to mitigate rent dissipation following the major oil discoveries of 1926 35 because of high bargaining costs firms chose prorationing instead of consolidation and unitization and success varied the analysis also shows that prorationing took the form it did because concession such as per well quotas were required to draw in small operations and the quotas led to predictable responses regarding rent dissipation prorationing despite its costs controlled total field production and costs conserved natural reservoir energies and lengthened field life when private agreements failed the parties successfully appealed for state enforcement since similar heterogeneities influnce regulations elsewhere in the economy detailed analysis of bargaining among firms is essential for insight into the emergence of various institutional forms 33 references 3 tables

what are the key drivers of mac curves a partial equilibrium modelling approach for the uk marginal abatement cost mac curves are widely used for the assessment of costs related to co2 emissions reduction in environmental economics as well as domestic and international climate policy several meta analyses and model comparisons have previously been performed that aim to identify the causes for the wide range of mac curves most of these concentrate on general equilibrium models with a focus on aspects such as specific model type and technology learning while other important aspects remain almost unconsidered including the availability of abatement technologies and level of discount rates this paper addresses the influence of several key parameters on mac curves for the united kingdom and the year 2030 a technology rich energy system model uk markal is used to derive the mac curves the results of this study show that mac curves are robust even to extreme fossil fuel price changes while uncertainty around the choice of the discount rate the availability of key abatement technologies and the demand level were singled out as the most important influencing factors by using a different model type and studying a wider range of influencing factors this paper contributes to the debate on the sensitivity of mac curves

strategic delay in market entry two firms are contemplating entry into a market that is viable for only one firm in a good state we show that even if each firm receives a signal that perfectly reveals a good state both might strategically delay entry owing to the fear that the other firm might enter in the same period as well we also find the conditions where the informed firm will let the rival firm know about the market s profitability and the two will merge to enter the market we discuss the applications of this model to the oil industry and the generic drug industry jel classification l71 d8

household balance sheet channels of monetary policy a back of the envelope calculation for the euro area abstract this paper formulates a back of the envelope approach to study the effects of monetary policy on household consumption expenditures we analyze several transmission mechanisms operating through direct partial equilibrium channels intertemporal substitution and net interest rate exposure and indirect general equilibrium channels net nominal exposure as well as wealth collateral and labor income channels the strength of these forces varies across households depending on their marginal propensities to consume their balance sheet composition the sensitivity of their own earnings to fluctuations in aggregate labor income and the responsiveness of aggregate earnings asset prices and inflation to monetary policy shocks we quantify all these channels in the euro area by combining micro data from the hfcs and the eu lfs with structural vars estimated on aggregate time series we find that the indirect labor income channel and the housing wealth effect are strong drivers of the aggregate consumption response to monetary policy and explain the cross country heterogeneity in these responses

heterogeneous life cycle profiles income risk and consumption inequality was the increase in income inequality in the us due to permanent shocks or merely to an increase in the variance of transitory shocks the implications for consumption and welfare depend crucially on the answer to this question we use consumer expenditure survey cex repeated cross section data on consumption and income to decompose idiosyncratic changes in income into predictable life cycle changes transitory and permanent shocks and estimate the contribution of each to total inequality our model fits the joint evolution of consumption and income inequality well and delivers two main results first we find that permanent changes in income explain all of the increase in inequality in the 1980s and 1990s second we reconcile this finding with the fact that consumption inequality did not increase much over this period our results support the view that many permanent changes in income are predictable for consumers even if they look unpredictable to the econometrician consistent with models of heterogeneous income profiles

decomposing trends in income volatility the wild ride at the top and bottom we use 2 year panels from the current population survey to provide a detailed accounting of family income volatility from 1980 to 2009 volatility doubled overall and the increase was most pronounced among the top 1 of the income distribution but in any given year the level of volatility among the bottom 10 exceeds that of the top the increased volatility comes from higher instability of head and spouse earnings other nonlabor income and from reduced covariance between these income sources with the tax system this suggests that current tax policy is less effective in mitigating income shocks than previous decades jel j31 i30

the hotspots reference routes and research trends of marginal abatement costs a systematic review abstract as one of the most effective means of evaluating environmental policies marginal abatement costs macs have been adopted in a growing body of research this study characterizes the mac related literature from 1993 to 2018 on web of science based on a systematic review bibliometric analysis and mind mapping the results classify the research hotspots into influential factors methods and empirical applications the three most frequently mentioned influential factors are technical change discount rates and energy prices compared with top down models bottom up models including engineering model and expert based method are the most widely used improvements in the former focus on strengthening market behavior effect while those in the latter aim to overcome the weaknesses of negative costs and lack of interaction across measures mac applications focus on environmental policies with two new research areas recently emerging co benefits and sectoral abatement costs furthermore a reference route is proposed by summarizing the applicability of methods and matching relationships among influential factors methods and empirical problems finally potential research directions are summarized based on the identified research hotspots and a similar co word analysis in marginal cost field such as considering the effects of both multiple influential factors and the interaction among factors on maccs

valuation of marginal co2 abatement options for electric power plants in korea the electricity generation sector in korea is under pressure to mitigate greenhouse gases as directed by the kyoto protocol the principal compliance options for power companies under the cap and trade include the application of direct co2 emission abatement and the procurement of emission allowances the objective of this paper is to provide an analytical framework for assessing the cost effectiveness of these options we attempt to derive the marginal abatement cost for co2 using the output distance function and analyze the relative advantages of emission allowance procurement option as compared to direct abatement option real option approach is adopted to incorporate emission allowance price uncertainty empirical result shows the marginal abatement cost with an average of 14 04 ton co2 for fossil fueled power plants and confirms the existence of substantial cost heterogeneity among plants which is sufficient to achieve trading gains in allowance market the comparison of two options enables us to identify the optimal position of the compliance for each plant sensitivity analyses are also presented with regard to several key parameters including the initial allowance prices and interest rate the result of this paper may help korean power plants to prepare for upcoming regulations targeted toward the reduction of domestic greenhouse gases

wealth and volatility we document that in the us over the course of the past century there has been a systematic negative relation between household wealth and business cycle volatility we develop a microfounded dynamic equilibrium model that contains elements of a traditional keynesian framework in which economic uctuations can be driven by sunspot type uctuations in household optimism or pessimism the novel feature is that the scope for equilibrium uctuations due to sunspots depends on the exogenously given value of household wealth when wealth is high consumers demand is not sensitive to unemployment expectations and the economy is robust to condence crisis when wealth is low consumers demand is sensitive to unemployment expectations the economy becomes vulnerable to condence driven uctuations and is in general more volatile in this case there is a potential role for public policies to stabilize demand we conclude by providing micro economic evidence on the importance of wealth in aecting the sensitivity of demand to aggregate conditions we show that during the great recession consumers with low

development of marginal abatement cost curves for the building sector in armenia and georgia abstract armenia and georgia are taking climate change agenda seriously and contributing to efforts for mitigating global climate change through various ways including preparation of low carbon development strategies for their future economic growth the improvement of energy efficiency is one of the key elements of the low carbon development strategies this study develops a methodology to estimate marginal abatement cost mac curve for energy efficiency measures and apply in the building sector in both countries the study finds that among the various energy efficiency measures considered the replacement of energy inefficient light bulbs i e incandescent lamps with efficient light bulbs is the most cost effective measure in saving energy and reducing greenhouse gas ghg emissions from the building sector most energy efficiency improvement options considered in the study would produce net economic benefits even if the value of reduced carbon is not taken into account while the mac analysis conducted demonstrates the cost competitiveness of various energy efficiency measures in armenia and georgia the study also offers a caution to policy makers to have supplemental analysis before prioritizing the implementation of these measures or introducing policies to support them

shortfall in on road fuel economy implications for public policy a prime factor in studying energy conservation in the usa has been the improvement in car fuel economy the environmental protection agency epa has published values for all models for several years these laboratory values often do not correspond to those found by motorists the differences in many cases between the two sets of data are substantial any future policies based on fuel economy will have to take into account the fact that on road values in miles per gallon are often much lower than the epa values the author devises a simple model to show the likely difference of petrol use in the usa using theoretical and actual fuel economies this amounts to about 5 000 million gallons between 1976 and 1985 over half of petrol use in 1978

a nonparametric method to estimate a technical change effect on marginal abatement costs of u s coal power plants the literature usually assumes that technical change reduces marginal abatement cost however recent results suggest that precisely the opposite occurs this paper proposes a nonparametric method to determine the effect of technical change on marginal abatement cost the method decomposes nox marginal abatement cost changes in 2000 2004 and in 2004 2008 for 325 boilers operating in 134 u s bituminous coal power plant into technical and non technical change effects we find that technical change reduces the nox marginal cost about 28 3 in 2000 2004 and 26 5 in 2004 2008 however more stringent regulations enacted the nox budget program results in lower nox emission levels as plant operators install more advanced nox abatement equipment which in turn causes an overall increase in marginal abatement cost

worker betas five facts about systematic earnings risk abstract the magnitude of and heterogeneity in systematic earnings risk has important implications for various theories in macro labor and financial economics using administrative data we document how the aggregate risk exposure of individual earnings to gdp and stock returns varies across gender age the worker s earnings level and industry aggregate risk exposure is u shaped with respect to the earnings level in the middle of the earnings distribution aggregate risk exposure is higher for males younger workers and construction and durable manufacturing at the top of the earnings distribution aggregate risk exposure is higher for older workers and finance

marginal abatement costs of carbon dioxide emissions in china a parametric analysis this paper investigates the technical inefficiency shadow price and substitution elasticity of hbox co 2 emissions of china based on a provincial panel for 2001 2010 using linear programming to calculate a quadratic parameterized directional output distance function we show that china s technical inefficiency increases over the period implying further scope for hbox co 2 emissions reduction in the medium and longer term at best by 4 5 and 4 9 respectively our results notwithstanding regional differences highlight increases in the shadow price of hbox co 2 abatement 1 000 yuan ton in 2001 to 2 100 yuan ton in 2010 additionally increasingly steep substitution elasticity highlights the difficult reality of reducing china s hbox co 2 emissions

the ranking of negative cost emissions reduction measures a flaw has been identified in the calculation of the cost effectiveness in marginal abatement cost curves maccs the problem affects negative cost emissions reduction measures those that produce a return on investment the resulting ranking sometimes favours measures that produce low emissions savings and is therefore unreliable the issue is important because incorrect ranking means a potential failure to achieve the best value outcome a simple mathematical analysis shows that not only is the standard cost effectiveness calculation inadequate for ranking negative cost measures but there is no possible replacement that satisfies reasonable requirements furthermore the concept of negative cost effectiveness is found to be unsound and its use should be avoided among other things this means that maccs are unsuitable for ranking negative cost measures as a result maccs produced by a range of organizations including uk government departments may need to be revised an alternative partial ranking method has been devised by making use of pareto optimization the outcome can be presented as a stacked bar chart that indicates both the preferred ordering and the total emissions saving available for each measure without specifying a cost effectiveness

estimates of ghg emission reduction potential by country sector and cost abstract in this study emission reduction potentials in greenhouse gases ghg are assessed by country sector and cost using a ghg emission reduction assessment model with high resolutions with respect to region and technology and high consistency in terms of assumptions interrelationships and solution principles model analyses show that large potential reductions can be achieved at low cost in developing countries and power sectors in addition cost efficient emission reductions were evaluated for some international emission reduction targets that have been derived on the basis of the principle of common but differentiated responsibilities among developed and developing countries if 1 emission reduction measures at negative costs and below 50 tco 2 for developed countries 2 intensity improvement measures for selected sectors at negative costs and below 20 tco 2 for major developing countries and 3 all emission reduction measures with negative costs for other developing countries in 2020 are adopted then emission reductions of 8 9 14 8 and 27 7 gtco 2 eq yr compared to the technology frozen case can be expected in developed countries major developing countries and globally corresponding to a 11 decrease 40 increase and 17 increase from 2005 levels respectively large scale emission reductions can be achieved even if co 2 intensity targets for major sectors are assumed for major developing countries

evaluating public policy mechanisms for climate change mitigation in brazilian buildings sector abstract this paper applies a multi criteria analysis mca and marginal abatement cost curves macc to evaluate public policies mechanisms to promote the dissemination of energy efficiency ee and on site renewable energy sources res technologies in brazilian buildings sector the objective here is to bring together the advantages of both methods in order to provide more valuable insights to policy makers the mca results show that in the case of more integrative policies which considers for instance potential of jobs creation the mechanisms to foster distributed res and solar water heaters are better ranked than in macc analysis where only cost effectiveness of each option is evaluated other key finding is that 1 there is a significant cost effective potential that could be reached through alternative mechanisms not implemented yet in the country such as public procurement regulation and building codes and 2 minimum energy performance standards meps could be broader in scope and more stringent and include the use of energy in standby mode and tubular fluorescent lamps in particular some important appliances such as large air conditioning devices should have more aggressive meps

who bears aggregate fluctuations and how the consumption of high consumption households is more exposed to fluctuations in aggregate consumption and income than that of low consumption households in the consumer expenditure cex survey the exposure to aggregate consumption growth of households in the top 10 percent of the consumption distribution in the cex is about five times that of households in the bottom 80 percent given real aggregate per capita consumption growth about 3 percentage points less than its historical mean during the past year these figures predict that the ratio of consumption of the top 10 percent to the bottom 80 percent has fallen by about 15 percentage points relative to trend using income data from piketty and saez 2003 we show that the income especially the wage income of rich households is more exposed to aggregate fluctuations so their higher income exposure is a likely contributor to their higher consumption exposure finally we find a striking change in the exposure of the incomes of high income households prior to the early 1980 s the incomes of high income households were not more exposed to aggregate fluctuations thus while high income households currently bear an inordinately large share of aggregate fluctuations this is a recent occurrence this abstract was borrowed from another version of this item

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

technical change and the marginal cost of abatement abstract we address one aspect of the treatment of technical change in the environmental economics literature how technical change impacts the marginal cost of abatement we review a selection of papers that employ a variety of representations of technical change and show that these representations have quite different and sometimes surprising effects on the marginal costs of pollution reductions we argue that these varied representations in fact correspond to a variety of different technology options we then present results indicating that this representation matters the impacts of technical change on the marginal cost of abatement can crucially impact policy analysis

the failure of marginal abatement cost curves in optimising a transition to a low carbon energy supply abstract one of the tools used to optimise actions in reducing the carbon intensity of the economy is to use marginal abatement cost mac curves whilst these are known to be imperfect they are widely used to prioritise actions and often in a way that is incorrect in particular whilst their use for measures which have positive costs and a net reduction in carbon emissions can correctly rank the measures for effectiveness use for ranking measures which have a net negative cost including a wide range of energy efficiency measures is entirely inappropriate and leads to perverse and incorrect outcomes as a result many assessments of low carbon actions are fundamentally flawed in their ranking of effectiveness and action is needed to overcome this and allow an optimum outcome an alternative approach is suggested here

the economic and budgetary impact of climate policy in portugal carbon taxation in a dynamic general equilibrium model with endogenous public sector behavior the objective of this paper is to study hbox co 2 taxation in its dual role as a climate and fiscal policy instrument using a dynamic general equilibrium model of the portuguese economy which highlights the mechanisms of endogenous growth and incorporates a detailed modeling of public sector behavior and accounts in addition to the conventional marginal abatement cost curve we present a pair of complementary marginal abatement cost curves which highlight the impact hbox co 2 taxation has on economic performance and public debt and are therefore directly relevant to the terms of the policy debate these marginal abatement cost curves provide an effective tool for understanding the rate at which the environmental effectiveness economic costs and budgetary effects change with the tax level our results indicate that hbox co 2 taxes can be an important policy instrument for reducing emissions and promoting fiscal consolidation although this will come at a cost in terms of economic performance simulation results suggest that a tax of 17 00 euros per hbox tco 2 can satisfy existing climate policy targets the tax revenue effects together with reductions in public spending yield a 4 8 reduction in public debt these desirable outcomes come at the cost of a 1 3 reduction in gdp over the long term our analysis highlights that limiting public consumption expenditures can contribute to larger reductions in public debt albeit at a marginally greater cost to economic activity in turn reducing public investment although effective in reducing public debt produces a much larger negative economic impact this evokes an important trade off particularly pronounced in the present debates regarding austerity measures in the eu between fiscal consolidation efforts and efforts to promote convergence to eu standards of living these results further highlight that modeling assumptions with respect to public spending decision are not innocuous an exogenous trajectory for public spending suggests substantially smaller gdp effects and substantially larger public debt effects for any given emissions target

capturing the least costly way of reducing pollution a shadow price approach abstract the production analysis literature is increasingly concerned with estimating marginal abatement costs yet most studies do not emphasize the ways in which pollutants may be reduced and their costs which makes them unable to identify the least costly compliance strategy this paper utilizes the materials balance principle to relate pollution to the employment of material inputs a production model which allows input and output substitution downscaling of operations pollution control and emission permits purchases as compliance strategies is proposed and the implications of joint and non joint pollution controls for the trade off between pollutants and desirable outputs are considered marginal abatement costs reflecting the least costly way of compliance are derived by exploiting the duality between the directional distance function and the profit function

an analysis of the costs of energy saving and co2 mitigation in rural households in china abstract households may imperfectly implement energy saving measures this study identifies two factors resulting in imperfect use of energy saving technology by households households often continue to use old technologies alongside new ones and the energy saving technologies have shorter actual lifetimes than their designed lifetimes these two factors are considered when computing marginal energy conservation cost and marginal co2 abatement cost using data collected from a survey of rural households in three provinces in china the results show that there are cost reduction for most space heating technologies and their marginal abatement cost under full implementation ranges from 60 to 15 usd t co2 while the marginal abatement cost of cooking technologies ranges from 12 to 85 usd t co2 the marginal abatement costs of the majority of technologies increased after accounting for the two implementation factors the marginal abatement cost in the imperfect implementation scenario is higher with a range of 1 to 15 usd t co2 for space heating and 18 to 165 usd t co2 for cooking assuming implementation factors are constant until 2035 annually achievable co2 abatement by 2035 is estimated to be 57 11 and 10 mt co2 y in hebei guizhou and guangxi provinces

exploration and development of u s oil and gas fields 1955 2002 we study the exploration and development of oil and gas fields in the u s over the period 1955 2002 we make four contributions to explain the economic evolution of the oil and gas industry during this period first we derive a testable model of the dynamics of competitive oil and gas field exploration and development second we show how to empirically distinguish hotelling scarcity effects from effects due to technological change third we test these hypotheses using statewide panel data of exploration and development drilling we find that the time paths of exploration development and total wells drilled are dominated by hotelling scarcity effects finally we offer an explanation for why fixed costs from exploration can make the contracting equilibrium in the mineral rights market efficient

energy efficiency and marginal carbon dioxide emission abatement cost in urban china abstract energy efficiency improvement and carbon emission reduction are two important ways to mitigate energy consumptions and global warming this paper aims to examine energy efficiency and carbon dioxide co2 emissions abatement costs of city urban areas in china to this end an improved slacks based measure approach is introduced which considers the linkage between desirable and undesirable outputs then measures of energy efficiency co2 emission abatement cost and comprehensive state index of co2 emissions abatement cost and co2 emissions reduction potential are defined the proposed model is then applied to the dataset of 285 cities in china during 2008 2012 the results show that most city urban areas in china have relatively low energy efficiencies surprisingly there are gradually narrowing gaps regarding mean energy efficiencies between areas during 2008 2012 nevertheless there are great disparities in energy efficiencies between cities within a typical area and even a provincial region it is found that co2 emissions abatement cost in urban china exhibits an increasing trend during the study period also significantly geographic disparities in abatement costs between areas regions and cites are found specifically energy efficiency has significantly positive correlation with the comprehensive state index in china some important findings and useful policy implications are achieved

greenhouse gas abatement cost curves of the residential heating market a microeconomic approach in this paper we develop a microeconomic approach to deduce greenhouse gas abatement cost curves of the residential heating sector our research is based on a system dynamics microsimulation of private households investment decisions for heating systems to the year 2030 by accounting for household specific characteristics we investigate the welfare costs of different abatement policies in terms of the compensating variation and the excess burden we investigate two policies i a carbon tax and ii subsidies on heating system investments we deduce abatement cost curves for both policies by simulating welfare costs and greenhouse gas emissions to the year 2030 we find that i welfare based abatement costs are generally higher than pure technical equipment costs ii given utility maximizing households a carbon tax is the most welfare efficient policy and iii if households are not utility maximizing a subsidy on investments may have lower marginal greenhouse gas abatement costs than a carbon tax

divide and conquer multiple leasing in common pool oil fields a theoretic model is developed to analyse strategic leasing behaviours of u s landowners in a non exclusively owned common oil pool oil field development is modelled as a simultaneous move two stage non cooperative game the landowners choose leasing strategies in the first stage independent lease operators choose extraction strategies in the second ownership structure is distinguished from operation structure and their relationship analyzed it is shown that in a non exclusively owned oil field it is individually rational for a landowner to subdivide his landholding and delegate production rights to multiple inde pendent firms although more dispersed production control leads to heavier common pool

the next generation of urban maccs reassessing the cost effectiveness of urban mitigation options by integrating a systemic approach and social costs abstract many cities are implementing policies and climate action plans yet local climate policies suffer from a lack of scientific understanding and evaluation methods able to support the definition of efficient mitigation strategies the purpose of this paper is to build on classical approaches in the energy policy field that exist at the national and international level to propose an urban maccs methodology able to fulfill this lack and inform local debates the methodology is an extension of static expert based maccs it combines a land use transport integrated model and an abatement cost methodology that integrates co benefits and takes into account the spatial and systemic dimensions of cities the methodology is implemented for the transportation sector of a mid sized european city grenoble france our results present the cost effectiveness and political feasibility of several proposed measures we find that the inclusion of co benefits can profoundly change the cost benefit assessment of transport mitigation options moreover we underline the key parameters determining the cost effectiveness ranking of mitigation options these urban maccs aim to serve as a bridge between urban planning and mitigation policies and can thus contribute to strengthen and align sustainable and climate change agendas at the local level

marginal abatement costs of greenhouse gas emissions a meta analysis in this paper we carry out a meta analysis of recent studies into the costs of greenhouse gas mitigation policies that aim at the long term stabilisation of these gases in the atmosphere we find the cost estimates of the studies to be sensitive to the stringency of the stabilisation target the assumed emissions baseline the way in which the time profile of emissions is determined in the model the choice of control variable co2 only versus multigas the number of regions and energy sources in the model and to a lesser degree the scientific forum in which the study was developed we find that marginal abatement costs of the stringent long term targets that are currently considered by the european commission are still very uncertain but might exceed the costs that have been suggested by recent policy assessments

are the costs of reducing greenhouse gases from passenger vehicles negative energy models suggest that the costs of reducing carbon emissions from transportation are high relative to those for other sectors this paper discusses why taxes or equivalent permit systems to reduce passenger vehicle emissions produce large net benefits rather than costs when account is taken of a their impact on reducing other highway externalities besides carbon and b interactions with the broader fiscal system both of these considerations also strengthen the case for a tax based approach over fuel economy regulation while fiscal considerations strengthen the case for taxes over grandfathered emissions permits the paper also comments on the practical relevance of automobile fuel taxes or their policy equivalents to broader legislation intended to mitigate climate change

divisionalization franchising and divestiture incentives in oligopoly a two stage game is used to model firms strategic incentives to divide production among autonomous competing units through divisionalization franchising or divestiture firms simultaneously choose their number of competing units which then engage in cournot competition while it is costly to form autonomous units each firm does so in equilibrium thus reducing firm profits and increasing social welfare relative to the case where firms cannot form competing units with linear demand and costs duopolists choose the socially optimal number of competing units oligopolies with larger numbers of firms choose too many the case of nonlinear demand is also examined copyright 1996 by american economic association

on the cost effectiveness of national economy wide greenhouse gas emissions abatement measures abstract this paper explores cost effective greenhouse gas abatement options for the european union member state of cyprus for those sectors of the national economy that are not subject to the european emissions trading system the analysis leads to the construction of a baseline and several alternative marginal emission abatement cost curves it addresses all economic sectors and considers all different types of mitigation measures improving energy efficiency switching to low or zero carbon fuels and inducing behavioural change towards public transport modes we apply nationally appropriate data that are mainly derived from local market information and judgement of national experts finally we present results of several sensitivity analyses which address main shortcomings of marginal abatement cost curves that have been identified in the literature and discuss the policy implications of each one of them apart from its relevance for eu member states this assessment is useful for all countries seeking guidance in their decarbonisation strategies

the usefulness of marginal co2 e abatement cost curves in austria energy efficiency measures are manifold in all economic sectors these measures can be pictured by a marginal abatement cost curve macc which is a common way to show co2 e abatement potential and its related costs in various fields in this paper we calculated the marginal co2 e abatement cost curve for austria for the first time to fulfill the need for country specific cost curves one of the strengths of such curves lies in their ability to highlight that energy efficiency measures can even have negative abatement costs the weaknesses consist of neglecting a change in energy prices the rate of diffusion and compatibility with existing technologies by using a static bottom up approach we constructed the macc for four economic sectors household service transport energy and found a national mitigation potential of 45 4 million tons co2 e the results further show that even with the measures with negative abatement costs it is possible to make the necessary co2 e mitigation to fulfill the kyoto protocol the conclusions emphasize that the curve makes a contribution to overcome one of the barriers of implementation by providing enhanced information on energy efficiency measures and its costs

when can carbon abatement policies increase welfare the fundamental role of distorted factor markets abstract this paper employs analytical and numerical models to assess the welfare effects of a revenue neutral carbon tax and nonauctioned carbon emissions permits taking into account preexisting tax distortions in factor markets the presence of preexisting taxes significantly raises the general equilibrium costs of both policies this cost increase is much greater under emissions permits since this policy does not generate revenues to reduce distortionary taxes under our central estimates emissions permits cannot increase welfare unless environmental damages exceed about 18 per ton of carbon in contrast an appropriately scaled carbon tax is welfare improving so long as environmental damages are positive

improving behavioral realism in hybrid energy economy models using discrete choice studies of personal transportation decisions hybrid energy economy models combine top down and bottom up approaches to explore behaviorally realistic responses to technology focused policies this research uses empirically derived discrete choice models to inform key behavioral parameters in cims a hybrid model the discrete choice models are estimated for vehicle and commuting decisions from a survey of 1150 canadians with the choice models integrated into cims we simulate carbon taxes gasoline vehicle disincentives and single occupancy vehicle disincentives to show how different policy levers can motivate technological change we also use the empirical basis for the choice models to portray uncertainty in technological change costs and emissions

the drivers of income inequality in rich countries rising income inequality has recently come centre stage as a core societal concern for rich countries the diagnosis of the forces driving inequality upwards and their relative importance remains hotly contested notably with respect to the roles of globalization versus technology and of market forces versus institutions and policy choices this survey provides a critical review and synthesis of recent research the focus is on income inequality across the entire distribution rather than only on what has been happening at the very top we pay particular attention to including what has been learned from the analysis of micro data to ensuring that the coverage is not unduly us centric and to analyses of the interrelations between the different drivers of inequality the marked differences in inequality trends across countries and time periods reflect how global economic forces such as globalisation and technological change have interacted with differing national contexts and institutions major analytical challenges stand in the way of a consensus emerging on the relative importance of different drivers in how income inequality has evolved in recent decades

marginal abatement cost curves for policy recommendation a method for energy system analysis abstract the transport sector is seen as one of the key factors for driving future energy consumption and greenhouse gas ghg emissions in order to rank possible measures marginal abatement cost curves have become a tool to graphically represent the relationship between abatement costs and emission reduction this paper demonstrates how to derive marginal abatement cost curves for well to wheel ghg emissions of the transport sector considering the full energy provision chain and the interlinkages and interdependencies within the energy system presented marginal abatement cost curves visualize substitution effects between measures for different marginal mitigation costs the analysis makes use of an application of the energy system model generator times for south africa times geeco for the example of gauteng province this study exemplary shows that the transport sector is not the first sector to address for cost efficient reduction of ghg emissions however the analysis also demonstrates that several options are available to mitigate transport related ghg emissions at comparable low marginal abatement costs this methodology can be transferred to other economic sectors as well as to other regions in the world to derive cost efficient ghg reduction strategies

lock in effect of emission standard and its impact on the choice of market based instruments abstract a country s existing emission standard policy will lead to a lock in effect when the country plans to adopt new market based instruments to control greenhouse gas emissions it must consider this effect as it chooses among instruments to avoid larger efficiency loss in this paper we find that the lock in effect will cause a kink point to occur on the marginal abatement cost mac curve this change of shape for the mac curve reminds us to be cautious in choosing market based instruments when applying weitzman s rule we also introduce this concept into a dynamic multi regional computable general equilibrium cge model for china and simulate mac curves for all regions after applying weitzman s rule we propose a timeline for introducing price instruments under different marginal benefit mb curve scenarios

innocent bystanders monetary policy and inequality abstract we study the effects of monetary policy shocks on and their historical contribution to consumption and income inequality in the united states since 1980 as measured by the consumer expenditure survey contractionary monetary policy systematically increases inequality in labor earnings total income consumption and total expenditures furthermore monetary policy shocks account for a non trivial component of the historical cyclical variation in income and consumption inequality using detailed micro level data on income and consumption we document some of the different channels via which monetary policy shocks affect inequality as well as how these channels depend on the nature of the change in monetary policy

international fish wars the strategic roles for fleet licensing and effort subsidies abstract this article examines the problem of noncooperative international fishing by analyzing the strategic rent shifting roles for such well known national management policies as fleet licensing and effort subsidies it is shown that the noncooperative equilibrium in each policy takes the form of a prisoner s dilemma with dissipated rents in the fishery it is also shown that strategic effort subsidies can only lead to incomplete rent dissipation but strategic fleet licensing can lead to complete rent dissipation the models developed in this article may help to provide an explanation for the persistence of large and excessively subsidized national fleets that exploit depleted international fish stocks

how to decarbonize the transport sector this article investigates possible evolution pathways for the transport sector during the 21st century globally and in europe under a climate change control scenario we attempt to shed light on the question how the transport sector should best be decarbonized we perform our study with the global bottom up energy systems model tiam ecn a version of the tiam model that is broadly used for the purpose of developing energy technology and climate policy scenarios which we adapted for analyzing in particular the transport sector given the global aggregated perspective of tiam ecn that in its current version yields at every point in time a single co2 price for different forms of energy use across geographic regions and economic sectors it generates a decarbonization process that for the transport sector occurs later in time than for the power sector this merely reflects that emission reductions are generally cheaper for electricity production than for transportation and that it is thus cost minimizing to spend limited financial resources available for co2 emissions abatement in the power sector first in our scenarios the use of hydrogen in internal combustion engines and fuel cells rather than electricity as energy carrier and batteries to store it gradually becomes the dominant transport technology this outcome is in agreement with some recent publications but is at loggerheads with the current popularity of the electric car based on sensitivity analysis we conclude that even if the establishment of a hydrogen infrastructure proves about an order of magnitude more costly than modeled in our base case electricity based transportation only broadly emerges if simultaneously also the costs of electric cars go down by at least 40 with respect to our reference costs one of the explanations for why the electric car is today by e g entrepreneurs often considered the supposed winner amongst multiple future transportation options is that the decision horizon of many analysts is no more than a few decades instead of a full century electric cars fit better the current infrastructure than hydrogen fueled vehicles so that from a short time perspective covering the next decade or two investments are not optimally spent by establishing an extensive hydrogen distribution network hence the path dependency created by the present existence of a vast power transmission and distribution network can make electricity the most efficient choice for transportation but only if the time frame considered is short electric transportation generally proves the more expensive alternative in our long term perspective except when electric car costs are assumed to drop substantially

how costly is mitigation of non co2 greenhouse gas emissions from agriculture a meta analysis this text reviews the assessments of marginal abatement costs of methane and nitrous oxide emissions from agriculture we use agricultural emissions and the corresponding prices collected from 21 studies that have assessed abatement potentials and costs using various modeling approaches and assumptions we first highlight the implications of the modeling approach for marginal abatement costs harmonized abatement rates for three emission prices 10 20 and 50 2005 tco2eq are regressed on variables that reflect various modeling assumptions and study characteristics in a second step the emission price is introduced as an explanatory variable when controlling for a few key characteristics of the studies the models explain an important share of the observed variability in abatement rates the type of modeling approach is found to have a significant effect in particular we find that equilibrium models lead to higher abatement rates for a given price the flexibility in nitrogen use and its effect on crop yields also plays a significant role in lowering marginal abatement costs the results of the second step indicate that the price elasticity of the abatement rate is about 0 6 this estimate is found to be robust to several specifications and consistent with previous assessments covering other economic sectors

cost effectiveness of greenhouse gas mitigation in transport a review of methodological approaches and their impact abstract a review is given of methodological practices for ex ante cost effectiveness analysis cea of transport greenhouse gas ghg mitigation measures e g fuel economy and co2 standards for road vehicles in the us and eu besides the fundamental differences between different types of policies and abatement options which inherently result in different cea outcomes differences in methodological choices and assumptions are another important source of variation in cea outcomes fourteen methodological issues clustered into six groups are identified on which thirty three selected studies are systematically reviewed the potential variation between lower and upper cost effectiveness estimates for ghg mitigation measures in transport resulting from different methodological choices and assumptions lies in the order of 400 per tonne co2 eq the practise of using cea for policy making could improve considerably by clearly indicating the specific purpose of the cea and its strengths and limitations for policy decisions another improvement is related to the dominant approach in transport ghg mitigation studies the bottom up financial technical approach which assesses isolated effects implying considerable limitations for policy making a shift to welfare economic approaches using a hybrid model has the potential to establish an improved assessment of transport ghg mitigation measures based on realistic market responses and behavioural change

decomposing the impact of alternative technology sets on future carbon emissions growth abstract what are the drivers of future global carbon dioxide co 2 emissions growth and how would the availability of key energy supply technologies change their relative importance in this paper we apply a novel index number decomposition technique to the results of a multi region multi sector computable general equilibrium model to quantify the influence of five factors on the growth of future carbon emissions 1 growth in global economic activity 2 shifts in the regional composition of gross world product 3 shifts in the sectoral composition of regions gdp 4 changes in sectors energy output ratios and 5 changes in the co 2 intensity of energy sources we elucidate how the relative importance of these factors changes in response to the imposition of a global carbon tax and alternative assumptions about the future availability of key energy supply technologies rising global economic activity and shifts in regional composition put upward pressure on emissions while changes in energy and emission intensity and the sectoral output mix have attenuating effects a global emission tax that increases over time slows economic expansion and shifts the fuel mix with the most pronounced impacts on china india and russia limited availability of carbon capture and storage nuclear and hydroelectric generation all lead to upward shifts in the long run marginal abatement cost curve causing some countries to choose to pay the tax rather than abate

the applicability of marginal abatement cost approach a comprehensive review abstract the marginal abatement cost mac methodology is widely used in climate change policies policy makers rely on mac to assess feasible strategies and related costs to achieve emission reduction goals this paper introduces a variety of mac methodologies aiming at solving diverse problems which utilizes various calculable logic thus producing different results and implications this study applies a mind mapping method to capture differentiation of mac methods and systematically classify mac methodologies the applicability path analysis was proposed based on principles such as stakeholder type decision making objectives cost concept strategy mode and information scope our goal is to assess the applicability of different methodologies to reduce misuse by policy makers and to serve as a guide for subsequent research which might prompt and lead to the derivation of more consequential results in future studies the results of this study suggest that the complex method is not always better than the simplified method because policy makers are required to select the appropriate method according to the type of information needed it may even be suggested that mac could be reliable by ranking relative value of options compared with baseline rather than focusing on the absolute value of individual measures

endogenous partial insurance and inequality in this paper we propose a model of endogenous partial insurance and we investigate its implications for macroeconomic outcomes such as wealth inequality asset accumulation interest rate and consumption smoothing to this end we include participation costs to state contingent asset markets into an otherwise standard aiyagari 1994 model we highlight the resulting nonmonotonic relationship between wealth and insurance market participation when insurance is costly poor households remain uninsured middle class households participate in the insurance market whereas rich households decide to self insure by only purchasing risk free assets after theoretically characterizing the endogenous partial insurance equilibrium we quantify its effect emphasizing the roles of a participation channel and an interest rate channel

which workers get insurance within the firm abstract industry level time series data suggest that low skilled workers get less insurance within the firm than high skilled workers in particular wages respond relatively more to productivity shocks in low skilled industries than high skilled industries our theory is that low skilled workers get relatively less insurance from their firms because they have relatively lower displacement costs under limited commitment lower displacement costs make the workers outside options more attractive and hence decrease the amount of risk sharing sustainable within the firm evidence on average displacement costs by industry support the theory s predictions

the neighbor effect simulating dynamics in consumer preferences for new vehicle technologies abstract understanding consumer behaviour is essential in designing policies that efficiently increase the uptake of clean technologies over the long run expert opinion or qualitative market analyses have tended to be the sources of this information however greater scrutiny on governments increasingly demands the use of reliable and credible evidence to support policy decisions while discrete choice research and modeling techniques have been applied to estimate consumer preferences for technologies these methods often assume static preferences this study builds on the application of discrete choice research and modeling to capture dynamics in consumer preferences we estimate canadians preferences for new vehicle technologies under different market assumptions using responses from two national surveys focused on hybrid gas electric vehicles and hydrogen fuel cell vehicles the results support the relevance of a range of vehicle attributes beyond the purchase price in shaping consumer preferences towards clean vehicle technologies they also corroborate our hypothesis that the degree of market penetration of clean vehicle technologies is an influence on people s preferences the neighbor effect finally our results provide behavioural parameters for the energy economy model cims which we use here to show the importance of including consumer preference dynamics when setting policies to encourage the uptake of clean technologies

why are exchange rates so smooth a household finance explanation abstract empirical moments of asset prices and exchange rates imply that pricing kernels are almost perfectly correlated across countries otherwise observed real exchange rates would be too smooth for high sharpe ratios however the cross country correlation among macro fundamentals is weak we reconcile these facts in a two country stochastic growth model with heterogeneous households and a home bias in consumption in our model only a small fraction of households trade domestic and foreign equities we show that this mechanism can quantitatively account for the smoothness of exchange rates in the presence of volatile pricing kernels and weakly correlated macro fundamentals

estimating the environmental efficiency and marginal co2 abatement cost of coal fired power plants in china abstract we estimate the environmental efficiency reduction potential and marginal abatement cost of carbon dioxide co2 emissions from coal fired power plants in china using a novel plant level dataset derived from the first and second waves of the national economic survey which were implemented in 2004 and 2008 respectively the results indicate that there are large opportunities for co2 emissions reduction in china s coal fired power plants given that all power plants operate fully efficiently china s co2 emissions in 2004 and 2008 could have been reduced by 52 and 70 respectively accompanied by an expansion in electricity output in other words the opportunities for double dividend exist in 2004 the average marginal abatement cost of co2 emissions for china s power plants was approximately 955 yuan ton whereas in 2008 the cost increased to 1142 yuan ton the empirical analyses show that subsidies from the government can reduce environmental inefficiency but the subsidies significantly increase the shadow price of the power plants older and larger power plants have a lower environmental efficiency and marginal co2 abatement cost the ratio of coal consumption negatively affects the environmental efficiencies of power plants

the cost of reducing co2 emissions integrating abatement technologies into economic modeling we explore two methods of incorporating bottom up abatement cost estimates into top down modeling an economy wide method and a sector specific method carbon emissions generally depend on technology and scale given the technology options abatement is possible without a substantial reduction in scale otherwise the change must come purely through a reduction in demand our analysis shows that the cost of environmental policy is considerably overestimated by top down models if a bottom up abatement cost curve is not included using the data for the swiss economy we demonstrate two techniques of representing an abatement function explicitly in a computable general equilibrium model a traditional and a hybrid discrete technology modeling approach the results suggest that the current climate policy in switzerland will not be able to move the economy towards the required 10 co2 reduction both approaches provide virtually the same results when the calibration process is precisely executed which contradicts the results of previous studies

the y factor for climate change abatement a method to rank options beyond abatement costs abstract the tools available to translate climate targets into abatement actions are mainly based on costs and technical feasibility options for greenhouse gas abatement span all sectors all countries and involve a huge variety of technologies the reasons for abatement to be realized or not are diverse and complex in particular the political discussion why many affordable options do not materialize is naive and ad hoc here we show the y factor an approach for a quick scan of abatement options against a set of prominent abatement barriers we define 12 factors which capture a broad set of barriers related to 1 costs and financing 2 multi actor complexity 3 physical interdependencies and 4 behaviour we rank 24 abatement options using an explicit but coarse scoring for these barriers we show that all abatement options have implementation barriers many of which may well drastically impact their implementation beyond what would be expected from their abatement costs the analysis implies that the relation between abatement costs and the barriers withholding implementation is not straightforward and calls for a deliberate policy debate on prioritization and policy intervention the y factor structures such a policy debate

impact of a carbon tax on the chilean economy a computable general equilibrium analysis abstract in 2009 the government of chile announced their official commitment to reduce national greenhouse gas emissions by 20 below a business as usual projection by 2020 due to the fact that an effective way to reduce emissions is to implement a national carbon tax the goal of this article is to quantify the value of a carbon tax that will allow the achievement of the emission reduction target and to assess its impact on the economy the approach used in this work is to compare the economy before and after the implementation of the carbon tax by creating a static computable general equilibrium model of the chilean economy the model developed here disaggregates the economy in 23 industries and 23 commodities and it uses four consumer agents households government investment and the rest of the world by setting specific production and consumptions functions the model can assess the variation in commodity prices industrial production and agent consumption allowing a cross sectoral analysis of the impact of the carbon tax the benchmark of the economy upon which the analysis is based came from a social accounting matrix specially constructed for this model based on the year 2010 the carbon tax was modeled as an ad valorem tax under two scenarios tax on emissions from fossil fuels burned only by producers and tax on emissions from fossil fuels burned by producers and households the abatement cost curve has shown that it is more cost effective to tax only producers rather than to tax both producers and households this is due to the fact that when compared to the emission level observed in 2010 a 20 emission reduction will cause a loss in gdp of 2 and 2 3 respectively under the two scenarios the tax value that could lead to that emission reduction is around 26 us dollars per ton of co2 equivalent the most affected productive sectors are oil refinery transport and electricity having a contraction between 7 and 9 analyzing the electricity sector by energy source the production of electricity from fossil fuels will decrease by 11 but electricity from renewables will increase by 43 electricity producers will pass the cost of the carbon tax to the consumer by increasing the price of electricity by 8 the findings of this paper will allow policy makers to take better and more informed decisions by providing a cross sectoral analysis of the impact on the economy of reducing emissions by 20 by implementing a national carbon tax
