co benefit of carbon mitigation on resource use in china abstract on one hand natural resources and energy provide the basis for life on earth but waste and emissions are produced during their throughput on the other hand china as the most populous country and an emerging economic powerhouse has taken on the challenge of hitting peak carbon dioxide co2 emissions by 2030 pursuing resource co benefits from carbon mitigation is an effective approach for china on the road to achieving the 2030 goal in this study we combine the computable general equilibrium cge model and the economy wide material flow accounts or analysis ew mfa method to estimate china s future co2 emissions and resource consumption and their co benefit effect three scenarios are analyzed business as usual bau nationally determined contributions ndc and the scenario of achieving the 2 degree target 2deg we find that both the ndc and 2deg targets can be achieved by 2030 without a significant compromise in economic growth with the effect of carbon mitigation china s resource consumption would rise by a factor of 1 7 bau 1 6 ndc and 1 5 2deg during 2012 2030 and the reduction in co benefits of metal ores nonmetallic minerals and fossil fuels would be 0 6 billion tons and 1 4 billion tons 0 8 billion tons and 2 0 billion tons and 2 6 billion tons and 4 6 billion tons for ndc and 2deg respectively sectoral disparity indicates that sectors with high emissions and resource consumption include traditional heavy industrial sectors and energy related sectors for which additional mitigation policies should be employed not only because they offer the most co benefit effects but they also have the least cost

economic analysis of coal price electricity price adjustment in china based on the cge model in recent years coal price has risen rapidly which has also brought a sharp increase in the expenditures of thermal power plants in china meantime the power production price and power retail price have not been adjusted accordingly and a large number of thermal power plants have incurred losses the power industry is a key industry in the national economy as such a thorough analysis and evaluation of the economic influence of the electricity price should be conducted before electricity price adjustment is carried out this paper analyses the influence of coal price adjustment on the electric power industry and the influence of electricity price adjustment on the macroeconomy in china based on computable general equilibrium models the conclusions are as follows 1 a coal price increase causes a rise in the cost of the electric power industry but the influence gradually descends with increase in coal price and 2 an electricity price increase has an adverse influence on the total output gross domestic product gdp and the consumer price index cpi electricity price increases have a contractionary effect on economic development and consequently electricity price policy making must consequently consider all factors to minimize their adverse influence

how to improve the performance of carbon tax in china abstract the chinese government committed to controlling carbon dioxide co 2 emissions and promoting development of non fossil fuels thus it becomes a top priority for the government to develop effective climate policies against such background this paper develops a new multi country computable general equilibrium cge model with detailed energy disaggregation this study evaluates the impact of single policy instrument carbon tax and combined policy mixes in order to investigate driving factors affecting the policy performance the main findings are as follows firstly the driving factors can be classified into two types the first type of factors affects cost effectiveness significantly while the second type generates considerable effect on emission performance secondly cross border externalities function as important barriers to the co 2 emission reduction since they imply extra competitiveness loss and result in considerable carbon leakage finally this paper considers two integrated policy mixes wherein carbon tax revenue is recycled to reduce capital tax or support clean energy subsidy these policy mixes can improve both cost effectiveness and emission performance and thus perform better than carbon tax alone in this way carbon tax revenue can be used to improve the performance looking ahead complicated policy mixes are preferred to improve the performance of china s carbon tax

the impact of a carbon tax on the susquehanna river basin economy abstract this paper presents the first study of the economic impacts of a carbon tax on an environmentally delineated sub national area the study is based on a 32 sector computable general equilibrium model of the susquehanna river basin srb of the us a special feature of the analysis is that it incorporates changes in prices of traded goods facing the focal region as a result of the imposition of a tax imposed globally the results show that a tax of 16 96 per ton of carbon could have rather negligible negative impacts on the srb economy as a whole but that the negative impacts on its energy industries could be sizeable also several sensitivity tests on closure rules and key parameter values indicate that the results are rather robust

inter factor inter fuel substitution carbon intensity and energy related co2 reduction empirical evidence from china carbon dioxide co2 reduction which is the central issue in addressing global warming depends on the extent that clean energy can substitute for co2 emitting coal and non energy factors can substitute for energy factor the purposes of this paper are to empirically investigate inter factor inter fuel substitution in china and to evaluate the determinants of china s energy related carbon intensity as well as mitigation effects of carbon tax considering china s rapid increase in energy consumption and the slow adjustment in substitution the two stage estimation method and the dynamic error correction mechanism are employed in this study the empirical results suggest substitutability among different types of energy sources as well as substitutability among energy labor and capital the magnitude of cross price elasticities indicates that the substitutions are inelastic which limits the scope of the chinese government to implement substitution strategy aiming at energy conservation and environmental management china s carbon intensity declined during 1985 2012 most of which can be attributed to labor substitution and energy price increase however carbon intensive technology being embodied in china s capital investment energy consuming equipment has contributed to the increase in carbon intensity a carbon tax of rmb 50 tonne could reduce 332 9 million tonnes co2 emissions on the basis of 2012 in addition if ignoring the feedback between inter factor inter fuel substitutions co2 mitigation potential would be underestimated

booming sector economic activity in paraguay 1973 86 a case of dutch disease the primary purpose of this study is to investigate the applicability of the dutch disease model as a means of explaining the changing sectoral composition of output for paraguay in the period 1973 86 the consequences of booming sector activity for 1 the distribution of income as it affects wages and 2 the in stability of export earnings for paraguay are examined the dutch disease model predicts that the consequences of booming activity will include a contraction of non booming sector activity as well as a real appreciation of the exchange rate these outcomes are tested in several single and multiple equation estimable models for the case of paraguay

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

models of export instability and empirical tests for less developed countries abstract alternative models are developed in which export earnings instability is generated by domestic supply domestic demand or foreign demand fluctuations their relative merits over the 1957 1972 period are examined through multiple regression analysis for a sample of 50 ldcs with breakdown into sub samples based on the type of commodity exported and the nature of foreign markets the results suggest that export instability originates mainly from foreign sources especially variations of market shares in foreign markets and commodity groups however domestic supply and demand fluctuations are the dominant factors for countries highly dependent on food exports geographic concentration is an important factor for countries dependent on food exports and developed country markets

when credit bites back using data on 14 advanced countries between 1870 and 2008 we document two key facts of the modern business cycle relative to typical recessions financial crisis recessions are costlier and more credit intensive expansions tend to be followed by deeper recessions in financial crises or otherwise and slower recoveries we use local projection methods to condition on a broad set of macro economic controls to study how past credit accumulation impacts key macro economic variables such as output investment lending interest rates and inflation the facts that we uncover lend support to the idea that financial factors play an important role in the modern business cycle

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

exploring the impacts of a carbon tax on the chinese economy using a cge model with a detailed disaggregation of energy sectors abstract this paper applies a computable general equilibrium model to investigate the impacts of a carbon tax on china s economy and carbon emissions based on china s 2010 input output table to obtain robust simulation results we further disaggregate the energy sectors into eight departments according to energy use characteristics the empirical results indicate that a moderate carbon tax would significantly reduce carbon emissions and fossil fuel energy consumption and slightly reduce the pace of economic growth however a large carbon tax has a significantly negative impact on china s economy and social welfare moreover a large carbon tax would entail marked price changes in china of the fossil fuels in use reducing coal consumption would have the greatest impact on reducing carbon emissions and the ad valorem duty rate for coal would be the highest after levying a carbon tax because it has the highest carbon emission coefficient therefore china should strive to promote clean coal technology which may be crucial to reducing carbon emissions moreover levying a carbon tax would improve the use of clean energy which would be an effective means of reducing carbon emissions therefore the chinese government should formulate the regulations for and pass a carbon tax as early as possible to achieve its carbon emission abatement target and further contribute to mitigating climate change

the impacts of china s household consumption expenditure patterns on energy demand and carbon emissions towards 2050 abstract this paper explores how china s household consumption patterns over the period 2005 2050 influence the total energy demand and carbon dioxide co2 emissions in two baseline scenarios and how it influences carbon prices as well as the economic cost in the corresponding carbon mitigation scenarios to this end we first put forward two possible household consumption expenditure patterns up to 2050 using the working leser model taking into account total expenditure increase and urbanization for comparison both expenditure patterns are then incorporated in a hybrid recursive dynamic computable general equilibrium model the results reveal that as income level increases in the coming decades the direct and indirect household energy requirements and co2 emissions would rise drastically when household expenditure shifts from material products and transport to service oriented goods around 21 000 mtce 1 of primary energy and 45 billion tons of co2 emissions would be saved over the 45 year period from 2005 to 2050 moreover carbon prices in the dematerialized mitigation scenario would fall by 13 in 2050 thus reducing the economic cost

geographic concentration and china s agricultural export instability this paper investigates the impacts of geographic concentration on china s agricultural export instability with a multiple region variance decomposition approach the decomposition results suggest that china s agricultural export concentration into the japanese market greatly lowers agricultural export instability while concentration into the hong kong south korea asean the us and russian federation markets increases export instability china s exports to the eu also lower its agricultural export instability further decomposition results indicate that the impacts of geographic concentration on different agricultural product export instabilities are different

the environmental and economic impact of the carbon tax in australia to fulfil its emission reduction target pledged in the copenhagen accord the australian government has determined to introduce a carbon tax from july 1st 2012 this paper simulates the effects on the environment and on the economy of a carbon tax of a 23 per tonne of carbon dioxide proposed by the government with and without a compensation policy we employ a computable general equilibrium model with an environmentally extended social accounting matrix according to the simulation results the carbon tax can cut emissions effectively but will cause a mild economic contraction because the price signal is intact the proposed compensation plan has little impact on emission cuts while significantly mitigating the negative effect of a carbon tax on the economy

forecast comparisons in unstable environments we propose new methods for comparing the out of sample forecasting performance of two competing models in the presence of possible instabilities the main idea is to develop a measure of the relative local forecasting performance for the two models and to investigate its stability over time by means of statistical tests we propose two tests the fluctuation test and the one time reversal test that analyze the evolution of the models relative performance over historical samples in contrast to previous approaches to forecast comparison which are based on measures of global performance we focus on the entire time path of the models relative performance which may contain useful information that is lost when looking for the model that forecasts best on average we apply our tests to the analysis of the time variation in the out of sample forecasting performance of monetary models of exchange rate determination relative to the random walk copyright 2010 john wiley sons ltd

do carbon taxes work analysis of government policies and enterprise strategies in equilibrium abstract to achieve the goal of carbon emission reduction a number of countries have implemented carbon tax policies and carbon pricing has become an important tool this paper discusses the interactions between a government and an enterprise for implementing carbon taxes over time or by level of tax considering greenhouse gas emission we examine the impacts of various carbon tax policies on enterprises investments in new technology their reductions in production quantity and governments tax remittances a case study of the strategic responses of three firms in taiwan s electronics cement and steel industries to two carbon emission policies promulgated by government shows that appropriate levels of tax can induce an enterprise to alter its production processes to achieve emission reduction as part of a long term business strategy

exploring the impacts of regional unbalanced carbon tax on co_2 emissions and industrial competitiveness in liaoning province of china carbon tax is regarded as a useful policy instrument to achieve the environmental target efficiently however the effect of regional unbalanced carbon tax is still unknown in this study an improved two region computable general equilibrium cge model is developed to fill this research gap with liaoning province and the rest of china roc as the study area business as usual bau and nine carbon tax scenarios are designed results show that in 2030 the highest carbon tax of 221 usd ton co 2 in taxc4p8 scenario in liaoning province will lead to carbon reduction of 44 92 with the cost of 5 54 gross domestic product gdp loss price effect and scale effect are the two mechanisms that affect the changes in gdp industrial output and co 2 emissions industrial structure energy consumption and carbon intensity of liaoning are overwhelmingly affected by the price effect most less energy intensive industries belong to the winner industries due to the higher influence of domestic market by contrast loser industries including most of the energy intensive industries are mainly affected by the changes of provincial and international markets roc region is mainly affected by the price effect suggestions about preferential developmental industries are offered to balance the environmental and economic concerns

age analysis of the impact of a carbon energy tax on the irish economy a computable general equilibrium model with specific detail in taxation and energy use is developed in this paper to quantify the impact of the implementation of energy taxation to reduce carbon dioxide emissions in ireland benchmark data combining physical energy and emissions data and economic data in the form of a social accounting matrix sam had to be compiled from various data sources because energy and pollution accounts from the seea are not available for ireland we find that the reduction target for energy related co2 emissions in ireland of 25 8 compared to 1998 levels can be achieved with a carbon energy tax of 10 15 euros per tonne of co2 though fuel switching is important in meeting the target this result is more sensitive to the possibilities for producers to substitute away from energy use welfare would fall but only by small percentages production and consumption patterns would change more significantly with a shift in demand from fuels with a high emission factor to energy sources with a lower carbon intensity and from energy to other commodities this paper confirms that a carbon energy tax leads to greater emission reductions than an equivalent uniform energy tax the latter has a stronger negative impact on the less polluting energy sectors whereas the carbon tax greatly stimulates the use of renewable energy and reduces the use of peat and coal the new sam the model and the application to energy taxes contribute to a better informed debate on environmental policy in ireland

economic and welfare influences of an energy excise tax in jiangsu province of china a computable general equilibrium approach abstract in recent years although china s energy intensity has gradually decreased the total consumption of energy commodities has increased sharply levying an excise tax on energy commodities is one of the keys to control energy consumption this paper constructed a computable general equilibrium model to simulate levying an energy excise tax in jiangsu province which is one of china s strong economic provinces with lower endowments of energy resources the results show that the energy excise tax is beneficial for energy saving while levying energy will cause economic and welfare declines when at a level tax rate of 5 10 and 15 the loss of gdp will reach 0 27 0 66 and 1 13 respectively and the incomes of inhabitants and enterprises alike will decrease when the energy tax revenue used to compensate for the welfare losses suffered by inhabitants or enterprises there is a double dividend effect energy saving and increasing income moreover the simulation indicated that a 5 improvement of energy efficiency brings about a backfire phenomenon with an increase of 142 in energy consumption however when considering the cost of energy efficiency improvements the rebound effect will be significantly decreased policy suggestions are further recommended to help improve the energy policy in regard to reducing energy consumption

exploring impact of carbon tax on china s co2 reductions and provincial disparities abstract with fast development it is not easy for china to achieve carbon reduction targets only by traditional command and control measures e g the measures for energy efficiency carbon tax is advocated as one effective complementary measure and has high possibility to be implemented for china s future low carbon development under such a circumstance this paper aims at forecasting the possible impact of carbon tax on both carbon reduction and economic loss of 30 chinese provinces a 30 chinese province cge computational general equilibrium model has been developed to conduct the provincial evaluation and seven scenarios including business as usual bau scenario and six carbon tax scenarios with carbon price from 20 usd ton to 120 usd ton up to 2030 are set the results show that china s industrial co2 will be reduced from 12 2 billion tons under bau scenario to 10 4 billion tons 9 3 billion tons 8 5 billion tons 7 9 billion tons 7 4 billion tons and 7 0 billion tons under scenarios of tax20 tax40 tax60 tax80 tax100 and tax120 in 2030 respectively electricity metal and chemicals sectors have high reduction potentials and are priority sectors for carbon tax policy provincial disparity analysis demonstrates that coal production consumption and total energy consumption are key factors to affect carbon tax effect on co2 reduction and inner mongolia shandong shanxi and hebei have the largest industrial co2 reduction potentials after levying carbon tax however the implementation of carbon tax will impede economic development for all provinces therefore the concept of carbon tax efficiency is further proposed in order to evaluate the effectiveness of carbon tax by considering both co2 reduction and gdp loss policy suggestions indicate that provinces of shanxi inner mongolia hebei and anhui should be set priority when implementing carbon tax policy in china and carbon price should be no more than 50 usd ton

examining the economic and environmental effects of emissions policies in china a bayesian dsge model abstract the purpose of this study is to build an energy emissions economy dynamic stochastic general equilibrium model to examine the economic and environmental effects of the carbon tax and carbon intensity target the model is calibrated to china s economy the results show that both the carbon tax and carbon intensity target policies have a negative effect on china s economy and environment however the carbon tax exerts more negative effects on the economy and environment than the carbon intensity target moreover the carbon tax shock lasts shorter than the carbon intensity target shock the findings additionally indicate that the effects of the increase in the productivity of energy sectors are greater than those of the increase in the productivity of other sectors thanks to the low carbon technology shock china s carbon dioxide emissions will reduce and output will increase taken together this study highlights the key policy implications associated with the results

input output analysis of co2 emissions embodied in trade the effects of sector aggregation abstract energy related co2 emissions embodied in international trade have been widely studied by researchers using the environmental input output analysis framework it is well known that both sector aggregation and spatial aggregation affect the results obtained in such studies with regard to the latter past studies are often conducted at the national level irrespective of country or economy size for a large economy with the needed data studies may be conducted at different levels of spatial aggregation we examine this problem analytically by extending the work of su et al su b huang h c ang b w zhou p 2010 input output analysis of co2 emissions embodied in trade the effects of sector aggregation energy economics 32 1 166 175 on sector aggregation we present a numerical example using the data of china and by dividing the country into eight regions it is found that the results are highly dependent on spatial aggregation our study shows that for a large country like china it is meaningful to look into the effect of spatial aggregation

effects of the internalization of the social cost of global and local air pollutants in chile abstract in 2017 environmental taxes on global pollutants co2 and local air pollutants so2 nox and pm began to be collected to reduce emissions in chile however large emitting sources only are subject to environmental taxes and the tax rates are much lower than the social cost of these pollutants which does not allow to fully internalize the generated damages for the above this study uses the environmental extension of the leontief price model and microsimulations to estimate the economic environmental distributive and poverty short term effects associated with the application of pigouvian taxes on all emissions generated by productive activities the results show that currently there are too many resources allocated to activities that generate strong negative externalities mainly in the electricity and transport sectors specifically the emissions are reduced almost 10 times more than in the current tax scenario if environmental taxes equal to social costs are applied but relevant negative indirect effects are generated that make the practical application of a tax of these characteristics unrealistic for example there is a fall between 1 2 and 2 9 in employment slightly worsening the income distribution and increases the poverty rate between 0 9 and 2 3 percentage points

the taylor rule and optimal monetary policy where it denotes the fed s operating target for the federal funds rate pt is the inflation rate measured by the gdp deflator yt is the log of real gdp and y t is the log of potential output identified empirically with a linear trend the rule has since been subject to considerable attention both as an account of actual policy in the united states and elsewhere and as a prescription for desirable policy taylor argues for the rule s normative significance both on the basis of simulations and on the ground that it describes u s policy in a period in which monetary policy is widely judged to have been unusually successful taylor 1999 suggesting that the rule is worth adopting as a principle of behavior here i wish to consider to what extent this prescription resembles the sort of policy that economic theory would recommend i consider the question in the context of a simple but widely used optimizing model of the monetary transmission mechanism which allows one to reach clear conclusions about economic welfare the model is highly stylized but incorporates important features of more realistic models and allows me to make several points that are of more general validity out of concern for the robustness of the conclusions reached the analysis here addresses only broad qualitative features of the taylor rule and attempts to identify features of a desirable policy rule that are likely to hold under a variety of model specifications

carbon taxation and market structure a cge analysis for russia abstract russia is one of the world s major sources of carbon based energy as well as one its most intensive users introducing carbon taxes can lead to a reduction in emissions and encourage investment in energy efficiency we investigate the economic effects of carbon taxes on the russian economy under perfect competition and a cournot oligopoly in output markets the main findings are i substituting carbon taxes for labour taxes can yield a strong double dividend in russia however welfare gains strongly depend on the labour supply elasticity and elasticities of substitution between capital labour and energy ii under the assumption of a cournot oligopoly with homogenous products and symmetric firms in the markets for natural gas petroleum and chemical products metals and minerals welfare costs of the environmental tax reform can be higher than under perfect competition this is because introducing carbon taxes leads to a reduction in already sub optimal output thereby exacerbating pre existing distortions arising from imperfect competition iii furthermore increases in energy costs can result in higher mark ups in some markets because of less competition resulting from firms exit

mind the gap a monetarist view of the open economy phillips curve abstract in many countries inflation has become less responsive to domestic factors and more responsive to global factors over the past decades we introduce money and credit into the workhorse open economy new keynesian model with this framework we show that i an efficient forecast of domestic inflation is based solely on domestic and foreign slack and ii global liquidity global money as well as global credit is tied to global slack in equilibrium then motivated by the theory we evaluate empirically the performance of open economy phillips curve based forecasts constructed using global liquidity measures such as g7 credit growth and g7 money supply growth instead of global slack as predictive regressors using 50 years of quarterly u s data we document that these global liquidity variables perform significantly better than their domestic counterparts and outperform in practice the poorly measured indicators of global slack that global liquidity proxies for

commodity decomposition of export import instability new zealand abstract this study examines instability of a country s income terms of trade in preference to its export receipts and uses a two step decomposition first the normalised variance of the income terms of trade is explained in terms of the variance of its two components the commodity terms of trade and the export quantity index then the variance of these indices is explained in terms of the variance of the individual commodity components the model is applied to the new zealand economy during 1962 1963 to 1978 1979 interaction terms account for a large part of the total variance indicating that the structure of the domestic economy is an important determinant of trade instability

assessment of china s climate commitment and non fossil energy plan towards 2020 using hybrid aim cge model china made a commitment in copenhagen to reduce its carbon dioxide emissions per unit of gdp from 40 to 45 compared with the 2005 level by 2020 and is determined to vigorously develop non fossil fuels this study analyzes the effects and impacts of policies that could help to achieve china s copenhagen commitments with a hybrid static cge model in which the electricity sector is disaggregated into 12 generation technologies four scenarios are developed including the reference scenario a the reference scenario b and two carbon constraint scenarios the results show that carbon intensity in terms of gdp will fall by 30 97 between 2005 and 2020 in the reference scenario a and will be reduced further by 7 97 if china s targeted non fossil energy development plans can be achieved in the reference scenario b however the rest of the 40 45 target must be realized by other measures such as carbon constraint it is also observed that due to carbon intensity constraints gdp loss would be from 0 032 to 0 24 compared to the reference scenario b and co2 emission reductions are due mainly to decreases in coal consumption in the electricity sector and manufacturing sector

terms of trade fluctuations and stabilization of producer prices by compensatory taxation abstract a small general equilibrium model is presented which highlights the role of the real exchange rate in the south in determining the terms of trade between the south and the north the dynamics of the model may generate terms of trade instability for some values of the parameters of the system compensatory taxation of export earnings by a stabilization fund in the south is shown to increase the likelihood of instability

does global liquidity help to forecast u s inflation we construct a measure of global liquidity using the growth rates of broad money for the g7 economies global liquidity produces forecasts of us inflation that are significantly more accurate than the forecasts based on us money growth phillips curve autoregressive and moving average models the marginal predictive power of global liquidity is strong at three years horizons results are robust to alternative measures of inflation

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

the impacts of carbon tax and complementary policies on chinese economy under the pressure of global warming it is imperative for chinese government to impose effective policy instruments to promote domestic energy saving and carbon emissions reduction as one of the most important incentive based policy instruments carbon tax has sparked a lively controversy in china this paper explores the impact of carbon tax on chinese economy as well as the cushion effects of the complementary policies by constructing a dynamic recursive general equilibrium model the model can describe the new equilibrium for each sequential independent period e g one year after carbon tax and the complementary policies are imposed and thus describe the long term impacts of the policies the simulation results show that carbon tax is an effective policy tool because it can reduce carbon emissions with a little negative impact on economic growth reducing indirect tax in the meantime of imposing carbon tax will help to reduce the negative impact of the tax on production and competitiveness in addition giving households subsidy in the meantime will help to stimulate household consumptions therefore complementary policies used together with carbon tax will help to cushion the negative impacts of carbon tax on the economy the dynamic cge analysis shows the impact of carbon tax policy on the gdp is relatively small but the reduction of carbon emission is relatively large

on the impacts of carbon tax and technological progress on china using a dynamic national computable general equilibrium model we investigate the impact of carbon tax and energy efficiency improvement on the economy and environment of china the chinese social

inflation as a global phenomenon some implications for inflation modeling and forecasting abstract we model local inflation dynamics using global inflation and domestic slack motivated by a novel interpretation of the implications of the workhorse open economy new keynesian model we evaluate the performance of inflation forecasts based on the single equation forecasting specification implied by the model exploiting the spatial pattern of international linkages underpinning global inflation we find that incorporating cross country interactions yields significantly more accurate forecasts of local inflation for a diverse group of 14 advanced countries including the u s than either a simple autoregressive model or a standard closed economy phillips curve based forecasting model we argue that modeling the temporal dimension but not the cross country spillovers of inflation does limit a model s explanatory power in sample and its pseudo out of sample forecasting performance moreover we also show that global inflation without domestic slack often contributes the most to achieve the gains on forecasting accuracy observed during our sample period 1984 q1 2015 q1 this observation according to theory is crucially related to the flattening of the phillips curve during this time period of increased globalization

globalization macroeconomic performance and monetary policy the paper argues that many of the exaggerated claims that globalization has been an important factor in lowering inflation in recent years just do not hold up globalization does however have the potential to be stabilizing for individual economies and has been a key factor in promoting economic growth the paper then examines four questions about the impact of globalization on the monetary transmission mechanism and arrives at the following answers i has globalization led to a decline in the sensitivity of inflation to domestic output gaps and thus to domestic monetary policy no ii are foreign output gaps playing a more prominent role in the domestic inflation process so that domestic monetary policy has more difficulty stabilizing inflation no iii can domestic monetary policy still control domestic interest rates and so stabilize both inflation and output yes iv are there other ways besides possible influences on inflation and interest rates in which globalization may have affected the transmission mechanism of monetary policy yes

the impacts of carbon pricing on coastal megacities a cge analysis of singapore abstract pricing carbon is a widely used policy instrument for climate change mitigation quantitative analysis of carbon pricing are mainly conducted at the regional and national level rarely at the city level due to data availability as a representative of coastal megacities that are vulnerable to both climate change and climate policies singapore has announced to impose carbon tax on large direct emitters as a complementary mitigation option to technical measures a city level computable general equilibrium cge model is developed to simulate potential impacts of carbon pricing on the city including paying border carbon adjustment bca on exports or introducing a domestic carbon tax different sector coverages and carbon tax revenue recycling schemes are investigated for domestic carbon tax the simulation results show that a domestic carbon tax is a more cost effective option than paying bca given an identical carbon price at s 10 t co 2 gdp total exports and household consumption would decline less and average abatement cost is much smaller in the carbon tax scenarios compared to the bca scenario in terms of absolute emissions reduction a carbon tax that covers energy manufacturing and land transport sectors would be preferred making emissions around 2 7 lower than 2010 baseline level
