co2 emissions of international freight transport and offshoring measurement and allocation abstract the growing offshoring process is the result of the fragmentation of production processes and the creation of global supply chains this process has increased final and intermediate imports but also the distance that goods travel in different stages until they reach the final consumer as well as the requirements of transport per unit of output and the volume of co 2 emissions generated in transporting them nowadays there is no generally accepted criterion for international transport pollution allocation no single country has the responsibility for emissions of international bunkers provided by ipcc in this paper we propose a new methodology for quantifying by sector the impact of international freight transport on total pollution and assigning responsibility to consumers this methodology considers the distance and the means of transport as key elements and uses input output methodology we apply this to the spanish economy combining data from input output tables import data and co 2 emission data the results show that the proportion of total co 2 emissions accounted for by emissions from international freight transportation allocated via the consumer criterion increase up to 4 16 between 1995 and 2000 as expected the industries where this offshoring process is more intense show the greatest increases in carbon emissions related to international transport these emissions are significantly higher than emissions embodied in domestic inputs in some of those industries where international fragmentation of production is relevant and increasing

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

will china s trade restructuring reduce co2 emissions embodied in international exports china s co2 emissions exports embodied in international trade has recently attracted more attention and raises questions on the liability and responsibility for environmental costs associated with chinese produced goods given that embodied emissions exports and imports are normal phenomena during international trade the key question focuses on china s reduction of embodied emissions exports via trade restructuring a trade restructuring optimization model combined with input output analysis and multi objective programming was established in this study in order to analyze the maximum volume of embodied emissions reduction within bearable cost constraints the results suggest that the trade off cost for china to reduce embodied emissions exports is very high additionally the net exports of china s embodied co2 emissions under a reasonable scenario can only be reduced by 3 26 previous policy suggestions on import export structure adjustments have limited effects on the reduction of china s embodied emission exports and unemployment is an important constraint on embodied co2 emissions export reduction even so china can still take advantage of various positive factors that have emerged in recent years to improve the industrial and energy consumption structures given that the increasing trend of china s embodied co2 emission exports has already changed gradually

random walk and the velocity of money some evidence from annual quarterly series abstract the random walk hypothesis is tested using annual data of the united kingdom and quarterly data of eight industrialized countries while annual series follow a random walk not all quarterly series do this sharply contrasts with the results of ahking 1982

china s balance of emissions embodied in trade approaches to measurement and allocating international responsibility international trade is characterized not only by the flow of capital and goods but also by the energy and emissions embodied in goods during their production this paper investigates the evolving role that chinese trade is playing in the response to climate change by estimating the scale of emissions embodied in china s current trade pattern and demonstrating the magnitude of the difference between the emissions it produces some of which are incurred to meet the consumption demands of the rest of the world and the emissions embodied in the goods it consumes estimating china s emissions on a consumption rather than a production basis both lowers its responsibility for carbon dioxide co2 emissions in 2006 from 5 500 to 3 840mtco2 and reduces the growth rate of emissions from an average of 12 5 per cent p a to 8 7 per cent p a between 2001 and 2006 the analysis indicates that a reliable consumption based accounting methodology is feasible and could improve our understanding of which actors and states are responsible for emissions for example recent emissions reductions by developed countries may lack credibility if production has merely been displaced to countries such as china moreover in the current institutional context production methodologies encourage leakages through trade that may do more to displace than to reduce emissions both equity and efficiency concerns therefore suggest that emissions embodied in trade should receive special attention in the distribution of post kyoto abatement burdens

examining the global environmental impact of regional consumption activities part 2 review of input output models for the assessment of environmental impacts embodied in trade this paper offers a detailed review of recently described single and multi region input output models used to assess environmental impacts of internationally traded goods and services it is the second part of a two part contribution in part 1 turner k lenzen m wiedmann t and barrett j in press examining the global environmental impact of regional consumption activities part 1 a technical note on combining input output and ecological footprint analysis ecological economics we describe how to enumerate the resource and pollution content of inter regional and inter national trade flows with the aim to illustrate an ideal accounting and modelling framework for the estimation of ecological footprints a large number of such environment economic models have been described but only in the last few years models have emerged that use a more sophisticated multi region multi sector input output framework this has been made possible through improvements in data availability and quality as well as computability we identify six major models that employ multi sector multi region input output analysis in order to calculate environmental impacts embodied in international trade results from the reviewed studies demonstrate that it is important to explicitly consider the production recipe land and energy use as well as emissions in a multi region multi sector and multi directional trade model with global coverage and detailed sector disaggregation only then reliable figures for indicators of impacts embodied in trade such as the ecological footprint can be derived

the increase in brazilian household income and its impact on co2 emissions evidence for 2003 and 2009 from input output tables abstract in recent years brazil has experienced economic growth and a recovery of income that has had a positive impact on the consumption of goods in this paper we evaluate the impact of brazilian household consumption on the co2 emissions for 2003 and 2009 using input output tables from the world input output database we used a semi closed model with eight household groups in order to apply the hypothetical extraction method in the consumption structure of each group further we use the result from the hypothetical extraction to evaluate the impacts of the structure consumption of each household group in terms of co2 emissions we find that there is a trade off between the households greater satisfaction from consumption and the increasing setback in emissions from the restructuring and modification of the consumption basket thus this study contributes to the research on emissions by mapping the recent behavior of the brazilian economy in terms of increased income changes in the consumption structure and their impacts on emissions the paper s aggregated results by income and consumption structure based on the intensity of the emissions and their systemic effects add to the discussions on less polluting production processes more conscious consumption of goods and more rational uses of energy and transportation

a first empirical comparison of energy footprints embodied in trade mrio versus plum abstract the ecological footprint as an indicator that accounts for human demand on global bioproductivity sets out to quantify the impacts associated with consumption in a given country including the impacts associated with trade the national footprint accounts nfa by global footprint network gfn calculate trade embodied footprints by multiplying yield and embodied energy factors with mass volumes of traded goods in a product land use matrix plum this article compares energy footprints embodied in trade from and to the united kingdom in 2002 as calculated by the nfa plum with the results from a recently developed multi region input output model mrio for the uk although totals for imports and exports are comparable breaking down the results by economic sectors reveals large differences and hardly any correlation between the two methods the omission of trade in services especially transport services and upstream impacts of energy goods fossil fuels and the use of inappropriate embodied energy factors in the nfa plum method are identified as the main reasons for these differences in the light of the results it seems that a comprehensive footprint account of trade can better be achieved with an input output based approach i conclude that mrio models once fully developed will be particularly suitable in the future to estimate the ecological footprints of imports and exports of nations with the possibility to track their origin via inter industry linkages international supply chains and multi national trade flows

a variance ratio test of random walks in foreign exchange rates the separate variance ratio tests under homoscedasticity and heteroscedasticity both provide evidence rejecting the random walk hypothesis using five pairs of weekly nominal exchange rate series over the period from august 7 1974 to march 29 1989 the rejections cast doubt on the random walk hypothesis in exchange rates which has received support in the existing literature furthermore since the rejections are robust to heteroscedasticity they suggest autocorelations of weekly increments in the nominal exchange rate series which may be consistent with the exchange rate overshooting or undershooting phenomenon in the past decade there has been a consensus that nominal exchange rates follow a random walk process since a unit root and uncorrelated increments are both required for a random walk process the random walk is usually supported in the existing literature either because a unit root component is detected in the exchange rate series or because the increment in the exchange rate is found to be serially uncorrelated for example meese and singleton 1982 and baillie and bollerslev 1989 both find a unit root component in the exchange rate series and the evidence provided in giddy and dufey 1975 cornell and dietrich 1978 logue sweeney and willett 1978 and hsieh 1988 all suggest that the exchange rate series contains uncorrelated increments in this paper the random walk hypothesis for the nominal exchange rate series is reexamined by applying a variance ratio test developed in lo and mackinlay 1988 to five pairs of weekly nominal exchange rate series over the period from august 7 1974 to march 29 1989 while there are two implications of the random walk unit root and uncorrelated increments this paper focuses on the uncorrelated increments aspect this is not only because there are some important departures from the random walk that unit root test cannot detect but also because the autocorrelation aspect may yield

fossil resource trade balances emerging trends for the uk abstract the aim of this paper is to examine the extent to which the uk can be classified as a net importer of fossil resources and a creator of pollution havens abroad between 1968 and 2000 using input output techniques and a derived resource flow classification system both the physical trade balance ptb and pollution trade balance utb associated with fossil resource use are computed the ptb shows that between 1968 and the early 1980 s the uk is presented as a net importer of direct fossil resource flows between 1984 and 2000 the uk is identified as a net exporter of direct fossil resources these trends are primarily explained by the uk s discovery and commercial production of north sea oil and gas fields in the late 1970s on the other hand the utb shows that over the whole period the indirect used flows attributable to the uk s exports are higher than those attributable to its imports these findings suggest that the uk did not create pollution havens abroad from the use of fossil resources between 1968 and 2000 however it is noticeable in both cases that from 1995 the uk s position as a net exporter has been decreasing considerably maturing north sea oil and gas fields set against increasing demands for fossil fuels and imported goods is signalling a return to the uk s pre 1984 dependence on direct imported fossil resources and the possible creation of pollution havens abroad knowledge of these trends contributes to the evidence base for the uk s changing import and export structure and the potential environmental repercussions at home and abroad

the impact of domestic trade on china s regional energy uses a multi regional input output modeling to systematically reveal how domestic trade impacts on china s regional energy uses an interprovincial input output modeling is carried out to address demand derived energy requirements for the regional economies in 2007 based on the recently available data both the energy uses embodied in final demand and interregional trade are investigated from the regional and sectoral insights significant net transfers of embodied energy flows are identified from the central and western areas to the eastern area via interregional trade shanxi is the largest energy producer and interregional embodied energy deficit receiver in contrast to guangdong as the largest energy user and surplus receiver by considering the impacts of interregional trade the energy uses of most eastern regions increase remarkably for instance shanghai hainan zhejiang beijing jiangsu and guangdong have their embodied energy requirements 87 49 19 97 13 64 12 60 6 46 and 6 38 times of their direct energy inputs respectively in contrast the embodied energy uses of some central and western regions such as inner mongolia shanxi xinjiang shaanxi and guizhou decrease largely the results help understand the hidden network linkages of interregional embodied energy flows and provide critical insight to amend china s current end reduction oriented energy policies by addressing the problem of regional responsibility transfer

shared producer and consumer responsibility theory and practice abstract over the past decade an increasing number of authors have been examining the nexus of producer versus consumer responsibility often dealing with the question of how to assign responsibility for internationally traded greenhouse gas emissions recently a similar problem has appeared in drafting the standards for the ecological footprint while the method traditionally assumes a full life cycle perspective with full consumer responsibility a large number of producers businesses and industry sectors have started to calculate their own footprints see www isa org usyd edu au adding any producer s footprint to other producers footprints or to population footprints which all already cover the full upstream supply chain of their operating inputs leads to double counting the sum of footprints of producers and consumers is larger than the total national footprint the committee in charge of the footprint standardisation process was hence faced with the decades old non additivity problem posing the following dilemma for the accounting of footprints or any other production factor if one disallows double counting but wishes to be able to account for producers and consumers then one cannot impose the requirement of full life cycle coverage the supply chains of actors have to be curtailed somehow in order to avoid double counting this work demonstrates and discusses a non arbitrary method of consistently delineating these supply chains into mutually exclusive and collectively exhaustive portions of responsibility to be shared by all actors in an economy

energy embodied in the international trade of china an energy input output analysis abstract growing international trade has not only positively affected the people s republic of china s china s economic development but also expanded the exportation of energy embodied in goods during their production this energy flow out will pose risks to china s rational utilization of natural resources as well as environmental protection in this paper we evaluate the energy embodied in goods produced in china during 1992 2005 and use input output structural decomposition analysis to identify five key factors causing the changes of energy embodied in exports direct primary energy efficiency primary energy consumption structure structure of intermediate inputs structure of exports and scale of exports for the three sub periods of 1992 1997 1997 2002 and 2002 2005 results show that china is a net exporter of energy and the energy embodied in exports tends to increase over time the expanding total volume of exports and increasing exports of energy intensive goods tend to enlarge the energy embodied in exports within all three sub periods but these driving forces were offset by a considerable improvement of energy efficiency and changes in primary energy consumption structure from 1992 to 2002 and the effects of structure of intermediate input only in the sub period from 1992 to 1997 from 2002 to 2005 the sharp augmentation of energy embodied in exports was driven by all the five factors our research has practical implications for the chinese economy results of this study suggest that the energy embodied in trade should receive special attentions in energy policies design to limit the energy resource out flow and pollution generation

international trade and environmental quality a survey abstract international trade has been incorporating various aspects of environmental issues since 1970 the extent to which environmental problems might affect many facets of trade or vice versa has been the subject of considerable debate over these years in this article we have attempted to establish some of the links between international trade and environmental quality by performing a comprehensive literature review we discuss issues such as establishing direct and indirect effects of international trade on environmental quality effects of trade on economic development environmental quality and energy and their relation with each other and finally the role of governments and international organizations in this context studies have so far revealed some linkages between trade and environment through conventional trade theory however interactions between international trade and types of pollution their sink and assimilative capacity need to be analyzed using a general equilibrium approach currently very little knowledge and agreement on the nature of interactions between trade theories development process and environmental quality exist existing studies have shown that the structure of environmental regulations should be modified to reflect the existence of trade under imperfect competition therefore further research on the interaction between new trade theory and environmental regulation is needed also theoretical and quantitative analysis regarding the effects of environmental regulations on competitiveness and location decision is needed the intensity and type of environmental measures vary across issues and countries therefore harmonizing environmental measures creates an inefficient atmosphere and to assume that trade restrictions will either improve or reverse the environmental damages is a serious mistake given the dynamic and intricate nature of the problem trade and environment debate continues despite vast research and poses a challenge for researchers and policy makers in the foreseeable future

from production based to consumption based national emission inventories abstract under the united national framework convention of climate change unfccc countries are required to submit national emission inventories nei to benchmark reductions in greenhouse gas ghg emissions depending on the definition and system boundary of the nei the mitigation options and priorities may vary the territorial system boundary used by the unfccc has been critiqued for not including international transportation and potentially causing carbon leakage to address these issues past literature has argued in favour of using consumption based nei in climate policy this article discusses several issues in moving from the standard production based nei to consumption based nei first two distinct accounting approaches for constructing consumption based nei are presented the approaches differ in the allocation of intermediate consumption of imported products second a consistent method of weighting production based and consumption based nei is discussed this is an extension of the previous literature on shared responsibility to nei third due to increased uncertainty and a wide system boundary it may be difficult to implement consumption based nei directly into climate policy several alternative options for incorporating consumption based inventories into climate policy are discussed

analysis of co2 emissions embodied in china s bilateral trade a non competitive import input output approach co2 emissions embodied in international trade are critical to the national carbon mitigation strategy studies estimating embodied co2 emissions in china often overestimate actual values this work calculates china s co2 emissions embodied in bilateral trade with the usa european union japan and other countries using a modified non competitive import input output method and latest data the results show that net co2 emissions embodied in china s trade in 2007 were only 400 million tons much lower than previous estimations accordingly china s co2 emission on the consumption side in 2007 dropped to 5 628 billion tons with the transfer part accounting for 6 6 of total co2 emissions calculated for the production side it is concluded that because co2 emissions embodied in trade are not as great as previously estimated china should place more emphases on energy saving and emission reduction on its own side instead of emission transfer to substantially mitigate co2 emissions

the effects of carbon taxation in china an analysis based on energy input output model in hybrid units abstract this paper evaluates the economy wide effects of carbon taxation in china to this end we build a price model based on an energy input output table in hybrid units that ensures the consistency of the analysis the results indicate that carbon taxation has small negative impact on gdp there are however relatively substantial emissions reductions to explore whether the impacts are spatially blind in the sense of having similar impacts on urban and rural residents the results of the distributional effects show that the impacts of carbon taxation on different urban household groups reveal small differences and are slightly regressive yet for rural residents carbon taxation may be significantly regressive in addition rural residents are found to be affected much more than urban residents furthermore the paper explores a policy intervention to investigate the effects of redistributing the carbon tax paid by households the main results reveal that reallocating the carbon tax to the groups with low income levels can offset the negative distributional effects significantly moreover the results of miyazawa style interrelational income multiplier analysis indicate that the household groups with high income would benefit significantly from the income increases in those with low income levels but not vice versa

against the wind bargaining recentralisation and wage inequality in norway 1987 91 in the late 1980s norway s labour market experienced similar supply and demand shifts for skills to other countries but unlike other oecd nations norway s wage setting system became more centralised the pay distribution in norway became more compressed at the bottom from 1987 to 1991 while low wage workers in other countries lost ground relatively using norwegian microdata for 1987 and 1991 i found that changing labour market prices helped cause this wage compression further the less educated had declining relative overall employment but increasing relative public sector employment both possible labour market responses to the wage compression

analysis of energy embodied in the international trade of uk interest in the role embodied energy plays in international trade and its subsequent impact on energy security has grown as a developed nation the uk s economic structure has changed from that of a primary producer to that of a primary consumer although the uk s energy consumption appears to have peaked it imports a lot of energy embodied in international trade alongside the more obvious direct energy imports the uk has seen increasing dependency on imported fossil energy since the uk became a net energy importer in 2005 in this paper an energy input output model is established to calculate not only the amount of fossil energy embodied in uk s imports and exports but also the sector and country distributions of those embodied fossil energy the research results suggest the following uk s embodied fossil energy imports have exceeded embodied fossil energy exports every year since 1997 uk embodied energy imports through the so called made in china phenomena are the largest accounting for 43 of total net fossil energy imports if net embodied fossil energy imports are considered the gap between energy consumption and production in uk is much larger than commonly perceived with subsequent implications to the uk s energy security

input output analysis of carbon emissions embodied in china japan trade abstractenergy related co2 emissions embodied in international trade have been widely studied by researchers all over the world by using the bilateral trade input output btio approach this study investigates the co2 emissions embodied in china japan trade during 1995 2009 and attempts to identify the driving forces for the change in co2 emissions embodied in china s exports to japan during that period by using structural decomposition analysis sda result shows that co2 emissions embodied in china s exports increased by about 100 from 1995 to 2009 whereas those embodied in china s imports increased by about 500 during the same period result of this research also reveals that the scale effect had a large influence on the increase in co2 emissions embodied in china japan trade the technical effect greatly decreased co2 emissions embodied in china s exports to japan but obviously increased those embodied in imports the influence of the structural effect was relatively small and insignificant in

assessing the influence of manufacturing sectors on electricity demand a cross country input output approach abstract the production and consumption of electricity is a major source of co2 emissions in europe and elsewhere in turn the manufacturing sectors are significant end users of electricity in contrast to most papers in the literature which focus on the supply side this study tackles the demand side of electricity an input output approach combined with a sensitivity analysis has been developed to analyse the direct and indirect consumptions of electricity by eighteen manufacturing sectors in fifteen european countries with indirect electricity demand related to the purchase of industrial products from other sectors which in turn require the consumption of electricity in their manufacturing processes we identify the industrial transactions and sectors which account for a greater share of electricity demand in addition the impact of an electricity price increase on the costs and prices of manufacturing products is simulated through a price model allowing us to identify those sectors whose manufacturing costs are most sensitive to an increase in the electricity price

austria s co2 responsibility and the carbon content of its international trade abstract seeking to limit global warming to 2 c puts narrow restrictions on the remaining carbon budget while the prevalent accounting framework for carbon emissions is production based production based principle pbp we here quantify the co2 emissions on the basis of the consumption based principle cbp for austria at a methodological level a multi regional input output model with full linkages is used to account for austria s co2 responsibility on a global scale estimates are carried out for the years 1997 and 2004 results show that during 1997 co2 responsibility based on cbp were 36 larger than those based on pbp this relation has increased through time the cbp indicator of 2004 was 44 larger than the pbp in terms of carbon emission location for each euro spent on austrian final demand in 2004 it is estimated that two thirds of the co2 emissions occur outside austrian borders regarding the origin of the emissions embodied in imports it is estimated that about one fourth originated in non annex i countries in 1997 this proportion increased to one third by 2004 due to this divergence between cbp and pbp indicators there is a need to re think current accounting bases in order to properly assign co2 responsibilities

international trade and the sustainability footprint a practical criterion for its assessment a simple and minimal criterion for sustainability is that the value of natural capital plus manufactured capital be not decreasing on the basis of any individual country or region the above simple comparison may be misleading as it does not take account of the production of goods for consumption in other countries regions via international trade in other terms the full environmental footprint of a country may not be properly assessed a method of calculating a weak sustainability criterion has been established for both a closed economy approach and an open economy approach there are significant differences between the open and closed economies measures for several regions particularly the middle east overall global sustainability on this criterion has been positive and increasing using a difference equation approach a further analysis has been made of the average proportional rate of change of global sustainability between 1980 and 1990 and its various regional and structural components have been determined these indicate that most of global sustainability growth can be attributed to western europe other asia and japan particularly through high savings ratios the usa on the other hand has made a very small net contribution to the growth in global sustainability

why ecological economics needs to return to its roots the biophysical foundation of socio economic systems abstract ecological economics was formally established in 1989 with the ambitious vision of developing a new economic paradigm embedding the social and economic systems in the biophysical world ecological economics had its roots in the biophysical understanding of economics that pioneers of the field georgescu roegen 1971 odum 1971 daly 1977 jansson 1984 martinez alier 1987 and others developed while studying the thermodynamic bedrocks shared by natural and social systems subsequently however ecological economics has explicitly but controversially adopted a big umbrella approach to methodological pluralism focusing more on topics such as valuing nature and its functions rather than attempting to understand and quantify the biophysical roots of economic activities biophysical economics was established in response to these concerns focusing more on developing analyses and models of the transformations of nature to generate wealth and approached mostly from an energy and material flows perspective the present paper argues that to achieve its original vision ecological economics must return to its biophysical roots collaboration between the two fields will help the next generation of thinkers to address the socio ecological challenges of the 21st century requiring an energy transformation called for by aspirations such as the green new deal and the un sustainable development goals

trade off analysis between embodied energy exports and employment creation in china moving towards sustainable consumption in china must factor in the drivers of production china s domestic energy demand is affected not only by domestic demand but also by foreign trade the accounting of energy embodied in china s international trade has attracted much attention in recent years in fact embodied energy imports exports are a part of the normal pattern of economic phenomena occurring through international trade with exports of embodied energy contributing significantly to china s economic development this research suggest that china s net embodied energy exports remained relatively stable before 2002 and then increased dramatically from 73 mtoe in 2002 to 502 mtoe by 2007 with an average annual growth rate of 47 2 over that period the total employment creation reliant on these exports is 191 3 million people including direct employment of 44 1 million people and indirect employment of 147 2 million people in 2007 and the total employment creation increased quickly between 2002 and 2007 with an average annual growth rate of 9 1 the share of employment created by exports in china s total employment increased from 16 5 in 1997 to 18 6 in 2002 and a more dramatic increase can be observed in 2007 of 28 1 the exports oriented sectors in china are energy intensive from the perspective of embodied energy consumption and the energy intensive exports are located in nearly the same sectors as the labor intensive exports china will find it difficult to sustain the trade off in costs due to unemployment if it wishes to reduce embodied energy exports china needs to exercise patience and long term reform to change the current development model because of its large economy and population base

applying physical input output analysis to estimate land appropriation ecological footprints of international trade activities in the last few years some studies have been presented which link land use accounting and input output analysis based on monetary input output tables miots for the calculation of direct and indirect land appropriation of production and consumption activities the compilation of the first comprehensive physical input output tables piots for some western european countries in the 1990s opened new possibilities for linking physical accounting and input output analysis using a physical multiplier for this kind of calculation is more appropriate as the most land intensive sectors are also the sectors with the highest amounts of material flows physical input output analysis illustrates land appropriation in relation to material flows of each of the sectors which is more appropriate from the point of view of environmental pressures than land appropriation in relation to monetary flows of a miot physical input output analysis has so far not been applied for any land related studies based on a physical input output model of the eu 15 physical input output analysis is applied in this paper in order to calculate direct and indirect land requirements for the production of exports from eu 15 to the rest of the world

trade and consumption of energy varieties empirical analysis of selected west africa economies abstract this paper examined the relationship between consumption of energy varieties total electricity and road transport and trade export and import in selected west african countries data spanning 1971 to 2010 was used to estimate vector error correction models vecm for 6 countries based on data availability empirical analysis showed that there is insignificant linkage between consumption of energy varieties and export of benin however there is a one way positive linkage running from energy varieties to import of the country for cote d ivoire energy varieties have insignificant relationship with export and import however while inverse relationship runs from export to both electricity and road transport energy consumption positive direct association runs from import to total energy and transport energy consumption with respect to ghana positive causality runs from electricity and road transport energy consumption to export however there is a significant positive feedback effect between import and electricity as well as road transport energy consumption for nigeria there is a significant positive link running from both electricity and road transport energy consumption to export and import senegal s case suggests a bi directional inverse linkage between export and total energy consumption for togo both export and import are insignificantly linked with energy use these mixed findings generate different policy implications across the selected west african countries which are well articulated in the paper

an overview of energy consumption of the globalized world economy abstract for the globalized world economy with intensive international trade an overview of energy consumption is presented by an embodied energy analysis to track both direct and indirect energy uses based on a systems input output simulation in 2004 the total amounts of energy embodied in household consumption government consumption and investment are 7749 874 and 2009 mtoe million tons of oil equivalent respectively the united states is shown as the world s biggest embodied energy importer 683 mtoe and embodied energy surplus receiver 290 mtoe in contrast to china as the biggest exporter 662 mtoe and deficit receiver 274 mtoe energy embodied in consumption per capita varies from 0 05 uganda to 19 54 toe rest of north america based on a forecast for 2005 2035 china is to replace the united states as the world s leading embodied energy consumer in 2027 when its per capita energy consumption will be one quarter of that of the united states

colombian international trade from a physical perspective towards an ecological prebisch thesis abstract prebisch s approach to economic development was based on the notion that there is an international historical division of labour peripheral countries are specialised in exporting primary goods while centre countries export industrial goods the terms of trade for peripheral countries tend to deteriorate this approach can be extended to ecological issues the international centre periphery division does not only involve the monetary exchange of goods and capital but also the physical exchange in which southern countries provide materials and energy so that northern countries can develop their socioeconomic metabolism this metabolic process is guaranteed through cheap prices for primary goods this paper aims to apply and extend prebisch s thought on unequal exchange both monetary and ecological in relation to colombian trade in the period 1970 2002 using material flow analysis

food miles carbon footprint and global value chains for spanish agriculture assessing the impact of a carbon border tax abstract we develop a multiregional input output model to evaluate the importance of international trade of agricultural products as well as their food miles emissions on the proposed extended carbon footprint ecf measure of spanish agriculture in 2000 2008 this measure of ecf incorporates the virtual carbon embodied domestic imported and international transport in the consumption of spanish products of agriculture plus the direct emissions or producer responsibility of the spanish agriculture sector our results show that spanish agriculture ecf in 2008 is 18 5 mt co 2 more than doubles the usual measure of carbon footprint the importance of these emissions leads us to calculate the effect of levying a carbon border tax on both embodied emissions and international freight transport in agriculture products on the price of agriculture products consumed by spanish households and bought by different spanish industries our results do not appear to impose too great a burden on the economy as a whole 3 7 over the value of imported agriculture products and 0 02 over total spanish domestic final demand however there might be a significant impact from taxing embodied carbon and transport emissions on some sectors and in terms of a potential change in the origin of imports with chinese and east asian exports into spain being the most affected

are output fluctuations transitory according to the conventional view of the business cycle fluctuations in output represent temporary deviations from trend the purpose of this paper is to question this conventional view if fluctuations in output are dominated by temporary deviations from the natural rate of output then an unexpected change in output today should not substantially change one s forecast of output in say five or ten years our examination of quarterly postwar united states data leads us to be skeptical about this implication the data suggest that an unexpected change in real gnp of 1 percent should change one s forecast by over 1 percent over a long horizon

participation in gvcs and co2 emissions abstract this paper attempts to explore the determinants of co2 emissions in the context of international trade while there exist studies that examine the roles of horizontal specialization and inter industry trade transactions little previous research attention has been paid to the roles of vertical specialization and intra industry trade transactions in affecting co2 emissions to fill the knowledge gap this study uses the panel data of 62 countries and regions for the period of 1995 2011 to estimate the effect of participation in global value chains gvcs on per capita co2 emissions major findings include 1 the relationship between participation degrees in gvcs and per capita co2 emissions is found to be inversely u shaped at the aggregate economy level and for most individual industries 2 per capita gdp shows an n shaped relationship with per capita co2 emissions and 3 benign drivers of co2 emissions include r d energy conservation and population control it can be concluded that countries with low gdp or gvc participation degrees are expected to experience worsening co2 emissions in the short or even medium run this trend however can be moderated or even reversed with more r d investments

prioritizing towards a green export portfolio for india an environmental input output approach abstract proponents of free trade have often hailed international trade as an engine of economic growth however the foreign trade sector like many other sectors in developing countries frequently involves these countries walking a tightrope between their developmental objectives and environmental goals in this regard prioritizing for developing a green yet internationally competitive export portfolio provides a quintessential win win solution to the problem this study factors in both environmental benignity indicated by total co2 emission intensity as well as trade competitiveness indicated by revealed comparative advantage index in identifying the ideal indian export portfolio the analysis calculates the level of direct and indirect emissions from the foreign trade sector exports and imports using the environmental input output eio matrix for 2003 04 for india that has been jointly developed by researchers from keio university japan and the energy and resources institute teri new delhi the derived basket is compared to the current portfolio to estimate the potential saving from compositional changes and to suggest directions for policymaking to emphasize or de emphasize the export of certain categories of exports

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

random walks and monetary velocity in the g 7 countries new evidence from a multiple variance ratio test the random walk hypothesis rwh of the velocity of money has often been supported for the developed economies the literature is however far from unanimous this paper employs the most recent methodological advances in testing for random walks the multiple variance ratio test to re examine the behaviour of the velocity of money in the g 7 countries monetary velocity is computed as the ratio of nominal income to contemporaneous money stock under alternative definitions of income and money the empirical results from the present study do not support the rwh in most of the g 7 countries with the us m1 and m2 velocities as exceptions furthermore the results show that the rwh is sensitive to either the definitions of monetary velocity or the sample period of study

structural decompositions of energy consumption between 1995 and 2009 evidence from wiod abstract energy is key to achieving sustainable development this paper explicitly distinguishes between the supply side of energy consumption and demand side of energy consumption and investigates the factors that affect the energy consumption across economies using data from the world input output database wiod this paper decomposes the relative changes of energy consumption into intensity effect production structure structural change in final demand total final demand effect and household consumption then it further decomposes production structure into inter industry structural effect and trade effect in intermediate inputs overall energy consumption growth is mainly driven by total final demand 55 04 increase at the world level but can be significantly reduced by intensity effect due to technological change 21 02 decrease at the world level there is heterogeneity of structure related effects across economies and within the same economy in both aspects of energy consumption in addition the trade effect and household effect are relatively small this paper provides an empirical framework for analyzing energy consumption in a globalizing world and suggests tailored and integrated energy policies

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

the random walk hypothesis of the velocity of money some evidence from five eec countries abstract this paper investigates the random walk hypothesis of the velocity of money using quarterly data from five eec countries for all five countries this hypothesis is not rejected by the data

promoting green productivity growth for china s industrial exports evidence from a hybrid input output model abstract stimulated by low labor cost and loose environmental regulations china s industrial exports have benefited significantly since joining the world trade organization wto however the extensive growth model in the past several decades has led to environmental degradation china is now shifting her development pattern to a more sustainable model using a hybrid input output model this paper found that total energy coefficients fell sharply between 1997 and 2002 and 2007 and 2012 the total energy consumption and co2 emission embodied in china s industrial exports grew by more than 100 from 2002 to 2007 with little variation from 2007 to 2012 subsequently malmquist luenberger productivity index mlpi is employed to assess the green productivity growth in the sector the decomposition of the mlpi is further conducted this suggests that efficiency changes from 2002 to 2007 and 2007 to 2012 are lower than 1 indicating that technical change is the main contributor to mlpi finally policy implications are provided with emphasis on dissemination of new conservation technologies

an empirical examination of the pollution haven hypothesis for india towards a green leontief paradox using input output analysis we examine whether india can be regarded as a pollution haven we calculate the extra co2 so2 and nox emissions induced by 1 billion rupees of additional exports this is compared with the reduction of indian pollution caused by an import increase of equal size in contrast to what the pollution haven hypothesis states for developing countries we find that india considerably gains from extra trade comparing 1996 1997 with 1991 1992 the gains have only increased indicating that india has moved further away from being a pollution haven the outcome is robust to changes in the underlying assumptions

impact of electrical intertie capacity on carbon policy effectiveness this study investigates the potential cost and emissions reductions that result from an increase in electricity transmission capacity between canada s two westernmost provinces alberta a fossil fuel dominated jurisdiction and british columbia a predominantly hydroelectric jurisdiction a bottom up model is used to find the least cost electricity generation mix in alberta and british columbia under different carbon policies the long term evolution of the electricity system is determined by minimizing net present cost of electricity generation for the time span of 2010 2060 different levels of intertie capacity expansion are considered together with a variety of carbon tax and carbon cap scenarios results indicate that increased intertie capacity reduces the cost of electricity and emissions under carbon pricing policies however the expandable intertie does not encourage greater adoption of variable renewable generation instead it is used to move low cost energy from the united states to alberta the optimal intertie capacity and cost reduction of increased interconnectivity increases with more restrictive carbon policies

changing industrial structure to reduce carbon dioxide emissions a chinese application abstract increasing concern about carbon dioxide co2 emission reduction demands knowledge about the production structure of an economy information on productive linkages yields insight about forward and backward emission effects associated with sectoral inputs and outputs and serves as an essential starting point to identify the optimised industrial structure under the constraint of co2 emission this paper proposes a combined linkage analysis and multi objective programming approach to identify the key co2 emission sectors and the optimised production structure with respect to emission reduction target as a demonstration the proposed approach is applied to data from china in 2007 the result shows that to reduce co2 emissions from 5707 16 to 5452 12 million tonnes china needs to change its industrial structure by focussing on industrial groups as defined by linkage characteristics which would lead to a subsequent gdp decrease of 82 59 billion yuan from a policy standpoint the analytical techniques described in this paper can provide valuable information for planners and decision makers to formulate feasible and practical industrial polices with implications for co2 emissions

china s foreign trade and climate change a case study of co2 emissions abstract the globalization of trade has numerous environmental implications trade creates a mechanism for consumers to shift environmental pollution associated with their consumption to other countries carbon leakage exerts great influences on international trade and economy applying an input output approach the paper estimates the amount of carbon dioxide co2 embodied in china s foreign trade during 1997 2007 it is found that 10 03 26 54 of china s annual co2 emissions are produced during the manufacture of export goods destined for foreign consumers while the co2 emissions embodied in china s imports accounted for only 4 40 1997 and 9 05 2007 of that we also estimate that the rest of world avoided emitting 150 18 mt co2 in 1997 increasing to 593 mt in 2007 as a result of importing goods from china rather than manufacturing the same type and quantity of goods domestically during 1997 2007 the net additional global co2 emissions resulting from china s exports were 4894 mt then the paper divides the trade embodied emissions into scale composition and technical effect it was found that scale and composition effect increased the co2 emissions embodied in trade while the technical effect offset a small part of them finally its mechanism and policy implications are presented

unilateral co2 reductions and carbon leakage the consequences of international trade in oil and basic materials a recursively dynamic general equilibrium model featuring six world regions with trade in energy and non energy goods is used to simulate the period from 1990 through 2100 in 10 year intervals the simulations explore the effect of unilateral action by the oecd to curb global co2 emissions unilateral cuts create incentives for free riding by non participating regions so that global emissions are reduced by less than the amount that the oecd cuts back its regional emissions carbon leakage occurs through two channels first basic materials production increases in unconstrained regions resulting in increased carbon intensity of gdp second reductions in oecd oil imports cause the world oil price to fall leading to an increased energy intensity in the non participant regions in this paper we use a general equilibrium model to assess the extent to which these two mechanisms reduce the effectiveness of oecd reductions in curbing global co2 concentrations

velocity and the variability of money growth evidence from granger causality tests comment in a recent issue of this journal hall and noble 1987 employ the grangercausality method to test milton friedman s 1970 hypothesis that money growth volatility is a causal factor in changes in velocity the background of hall and noble s investigation is based on 1 the controversial marked decline in m 1 velocity in 1982 and 2 the apparent weakening of the money nominal gnp linkage implicit in the velocity decline this latter aspect of the drop in velocity would appear to undermine a basic plank of monetarism and has been described by robert gordon 1983 as the demise of monetarism friedman 1984 has countered this argument by relating the velocity decline in part to the unprecedented volatility of money growth following the federal reserve s 1979 shift to nonborrowed reserves targeting implicit in friedman s reasoning is that general uncertainty regarding money growth enters as an important argument in the public s money demand function thus friedman explains the 1982 velocity decline does not undermine monetarism rather it reflects one aspect of general portfolio readjustment under conditions of extreme perceived monetary uncertainty and the elnancial instability that characterized the period using quarterly data from 1963 i through 1984 ii hall and noble granger test the friedman hypothesis by estimating the following regression

firm size wage differentials in switzerland evidence from job changers using information on job changes and search behavior of workers and controlling for endogenous mobility we study firm size wage differentials in switzerland we find that the observed cross sectional firm size premium cannot be explained exclusively by worker heterogeneity almost 50 of the cross section differential is a firm size effect this abstract was borrowed from another version of this item

energy requirements of households in brazil abstract in this study we determine the total direct plus indirect energy requirements of a given set of brazilian households we use a generalized input output model in order to calculate the energy embodied in goods and services purchased by households of different income level in 11 capital cities of brazil our results show that on average the total energy intensity of household expenditure increases with income level although there is a considerable spread in energy intensities within income classes as well as disparities between regions of the country the total yearly average energy requirement per household in brazil in 1995 96 was 173 6 gj 61 of which was indirect with 32 8 gj for the lower income level 66 of which was indirect and 602 2 gj for the higher income level 62 of which was indirect of this total average energy requirement 76 was required for only three consumption categories utilities 31 mobility 28 and shelter 17 this analysis calls for the attention that has to be given not only to the direct energy consumption as motor fuels and electricity for example but also to the consumption categories that encompass an important part of the indirect energy requirement of households in capital cities in brazil

international trade and shared environmental responsibility by sector an application to the spanish economy abstract the aim of this paper is to define a shared responsibility criterion for analysing the impact of international trade on co 2 emissions applied to sectors with the approach proposed it is possible for sectors in a country to account for only a part of the emissions associated with exported and imported goods the agents considered as responsible for pollution are sectors two fold as producers and suppliers of intermediate inputs and final demand accounting for direct emissions linked to production and as consumers of intermediate inputs required for production accounting for direct and indirect emissions linked to consumption of inputs and the countries and foreign sectors that trade with these industries the responsibility of emissions is shared by all the participants along the global product chain depending on the value added of each step the criterion is applied to the spanish economy for the period 2000 to 2005 and proves useful for determining what economic policies may be suitable for mitigating anthropogenic impact on the environment and for including all the agents of the supply chain in the development of sustainable supply chain management

has energy conservation been an effective policy for thailand an input output structural decomposition analysis from 1995 to 2010 abstract thailand has depended heavily on imported fossil fuels since the 1990s which hindered the nation s economic development because it created uncertainty in the nation s fuel supply an energy conservation policy was implemented in 1995 to require industries to reduce their energy intensity ei and consumption immediately this study investigates the effectiveness of the policy between 1995 and 2010 using the hybrid input output approach surprisingly ei improvement was observed in only a few sectors such as transportation non metallic paper and textile an embodied energy decomposition analysis revealed that while households were the largest energy consumer in 1995 energy consumption in exports exceeded that of households in 2000 2005 and 2010 in addition structural decomposition analysis revealed the final demand effect was the strongest factor in determining the efficacy of energy conservation whereas the energy efficiency effect was not an effective factor as expected for decreasing energy consumption policy barriers and conflicting economic plans were factors that affected the outcome of these energy policies

balanced matching and labor market equilibrium we analyze equilibrium in a labor market model wherein it takes time for the workers to contact firms workers assumed identical repeatedly sell their labor services all through their work lives choosing their search intensity endogenously identical firms attempt to maximize their steady state profit flow we focus on the importance and consequences of balanced matching in which workers are more likely to contact a larger firm a unique equilibrium is shown to exist wherein all firms offer the same wage and select an employment level at which wage equals marginal product the effect of traditional labor market policies and empirical implications are discussed

energy and carbon embodied in the international trade of brazil an input output approach abstract all goods and services produced in an economy are directly and or indirectly associated with energy use and according to the type of fuel utilized with co2 emissions as well international trade is an important factor in shaping the industrial structure of a country and consequently in affecting a country s energy use and co2 emissions this study applies input output techniques to the brazilian economy to evaluate the total impacts of international trade on its energy use and co2 emissions a commodity by industry io model in hybrid units energy commodities in physical units and non energy commodities in monetary units is applied to the brazilian economy in 1995 results show that total energy embodied in the exports of non energy goods of brazil equals 831 pj while total carbon embodied is 13 5 mtc these amounts are larger than the relevant amounts embodied in the imports of non energy goods respectively 679 pj and 9 9 mtc these figures are better understood by contrasting them with the total energy use and the corresponding total carbon emissions of the brazilian economy in 1995 estimated by this work 6781 pj and 99 4 mtc respectively this means that international inflows and outflows of energy embodied in non energy goods are in the order of 10 and 12 of the total energy use while inflows and outflows of carbon embodied in non energy goods are approximately 10 and 14 of the corresponding total carbon emissions of the brazilian economy in 1995 the general picture is that brazil is not only a net exporter of energy 153 pj and of carbon 3 6 mtc embodied in the non energy goods internationally traded by the country in 1995 but also that each dollar earned with exports embodied 40 more energy and 56 more carbon than each dollar spent on imports these findings suggest that brazilian policy makers should be concerned about the extra impacts international trade policy may have on energy use and carbon emissions of the country

employer size or skill group size effect on wages the authors analyze explanations for firm or establishment size effects on wages one theory is that each firm faces an upward sloping supply curve for labor implying that the number of any particular type of worker should matter for his or her level of pay rather than the total number of workers in the firm to test this hypothesis the authors add the log of skill group size to the standard log wage equation results indicate that the traditional employer size effect on wages dwindles away once control for the number of workers of the same skill group educational type as the observed individual within the establishment is added to the equation the skill group size effect on wages is substantial after controlling for both individual and establishment specific heterogeneity a dwindling employer size effect and a significant group size effect remain

establishment size and task specific wages evidence from historical contract data this study examines whether task specific jobs are rewarded differently across establishments of different sizes and whether these rewards vary across distinct technologies we found that the aggregate premium estimates on the impact of size on wages conceal significant differences between tasks and technologies and that these differences reflect unobserved individual heterogeneity the role of self selection of more productive workers into larger establishments is particularly substantial in the case of abstract tasks

recalculating co2 emissions from the perspective of value added trade an input output analysis of china s trade data abstract using traditional trade statistics to calculate co 2 emissions embodied in international trade results in significant miscalculations and a deeper divide between countries the aim of this research is to provide a reasonable estimate of carbon emissions to help policymakers in each country address their actual share of responsibility this study employs the world input output database and the gross export decomposition methodology to recount the co 2 emissions embodied in china s international trade from the perspective of value added trade the result shows that reliance on traditional statistics caused a significant overestimation of china s imports and exports us 398 77 billion and us 504 46 billion for china s imports and exports respectively our findings suggest that 177 24 million tons of carbon emissions embodied in imports and 907 636 million tons of carbon emission embodied in exports were over calculated the result obtained with traditional calculation methods has artificially increased the responsibility share of china in the global emissions reduction we also compare the co 2 emission coefficients of china with those of other countries our findings suggest that the high emission coefficients of most chinese industrial sectors determine the carbon emissions embodied in china s exports to be higher than in its imports

scale technique and composition effects in trade related carbon emissions in china this study applies structural decomposition analysis to evaluate the scale composition and technique effects of trade related carbon emissions in china mainland from 1987 to 2007 the initial findings indicate that the increasing magnitude of china s trade both in terms of the carbon emissions embodied in exports and the carbon emissions avoided via imports had large scale effects during the whole period the technique effect caused by changes in input mix sector energy intensity fuel mix and carbon coefficients effectively offset part of the scale effect during the entire period but failed to do so during some sub periods changes in trade composition caused a relative small increase in the carbon emissions created by exports but a relative small decrease in the carbon emissions avoided via imports during the whole period

measuring progress towards carbon reduction in the uk the uk climate change bill proposes to establish legally binding targets for a 60 reduction in carbon dioxide emissions by 2050 this paper discusses the challenges posed by measuring progress towards this target it takes as a premise that the conventional productionbased accounting framework enshrined in the unfccc emissions accounting guidelines is inappropriate for this task because it fails to account for the carbon traded across the uk national boundary accordingly it sets out a consumption based accounting framework using a two region environmental input output eio model which could in principle measure progress in reducing the emissions attributable to final consumers in the uk it illustrates the use of this framework to measure the reduction in carbon dioxide achieved by the uk between 1990 the kyoto base year and the year 2004 and compares this against the production perspective the results indicate that any progress towards the uk s carbon reduction targets visible under a production perspective disappears completely when viewed from a consumption perspective but the robustness of this conclusion depends critically on the accuracy of underlying economic and environmental data sets as well as specific assumptions concerning imports by analysing the consistency of uk input output data we conclude that eio is still some way from being able to answer the critical question of the carbon trade balance for the uk in these circumstances measuring real progress towards carbon reduction in the uk remains elusive

examining the global environmental impact of regional consumption activities part 1 a technical note on combining input output and ecological footprint analysis in recent years there have been a number of attempts to develop a more comprehensive approach to the issue of measuring resource use and or pollution generation embodied in trade flows including contributions that combine input output techniques and ecological footprint analysis in this two part paper we describe how to enumerate the resource and or pollution content of inter regional and inter national trade flows part 1 and we present a literature review of recent methodological and empirical developments part 2 it is straightforward in principle to extend the basic input output approach to capture international trade flows however in practice problems of data availability and compatibility and of computability of extended input output matrices mean that simplifying assumptions are generally applied but with the implications of these assumptions often not made fully explicit what appears to be absent from previous applications is an account of the analytical method by which ecological footprints should ideally be estimated in an international input output accounting analysis this allows an explicit analysis of the problems that prevent the application of the full method and identification of the most appropriate short cut methods in a transparent way the objective of this paper is to provide such an account

manpower programs in a local labor market a theoretical note a major aspect of social policy in the united states during the 1960 s was the effort to increase employment and lessen the extent of poverty the effects of these efforts in particular those of the manpower development and training act have been discussed by economists solely within the framework of empirical cost benefit analysis in this note we take a different approach to the study of manpower programs under a set of admittedly restrictive assumptions we analyze the relative efficiencies in reducing unemployment of several alternative subsidy programs it should be remembered that the reduction of unemployment is merely one goal of these programs and that the usefulness of our result must be qualified accordingly

sharing responsibility for carbon dioxide emissions a perspective on border tax adjustments concerns about the equity and efficiency of current allocation principles related to responsibility for carbon dioxide co2 emissions have been presented in the recent literature the objective of this paper is to design a calculation framework for shared responsibility from the perspective of border tax adjustments the advantage of this framework is that it makes the shared responsibility principle and border carbon taxation complementary to each other these are important policies for reducing global co2 emissions but they are individually supported by developing and developed countries as an illustration the proposed framework is applied to data from china in 2007 the empirical results show that for the chinese economy as a whole changing from the production based criterion to the shared responsibility approach would lead to an 11 decrease in its responsibility for co2 emissions moreover the differences observed between the production based criterion and the shared responsibility approach are considerable in several sectors for example changing from the production based criterion to the shared principle would lead to a 60 decrease in the responsibility of the textile sector

specialization patterns and reduction of co2 emissions an empirical investigation of environmental preservation and economic efficiency abstract we study the effects that different degrees of specialization in the production of the global net output of a group of countries might have on the emissions of co2 the analysis is based on the sraffian notion of subsystems which allows us to study what the input output table of a country would look like under different hypotheses on the allocation of the available resources we use the wiod input output tables and the related environmental accounts for 1995 2009 we show that the environmental benefits deriving from appropriate specialization patterns could be substantial moreover our results suggest that co2 reduction is not necessarily detrimental to economic activity on the contrary with the appropriate exploitation of suitable patterns of specialization co2 reduction and gdp growth may even be pursued jointly

velocity effects of anticipated and unanticipated money growth and its variability the purpose of this paper is to empirically test the relationship between velocity growth and anticipated and unanticipated money growth and its variability in particular by decomposing actual monetary growth into anticipated and unanticipated components the study investigates whether knowledge of past variability of anticipated and unanticipated monetary growth improves the prediction of future velocity growth beyond predictions that are based on past velocity growth alone this is the empirical definition of granger causality comparasions are made in all tests among simple sum and divisia aggregates of m1 m2 m3 and l and with spindt s monetary velocity mq aggregate

energy use and structural changes factors behind the fall in sweden s energy output ratio abstract this paper examines the causes behind the fall in sweden s use of energy in relation to real gdp after the energy crisis 1973 1974 the author uses historical and statistical data as well as economic theory especially input output analysis to analyse effects on the energy output ratio of the changes in sectoral energy use and of variations in the composition of final demand the results obtained are used to assess the energy implications of alternative strategies for economic policy actually discussed in sweden for the early 1980s

co2 emissions embodied in china us trade input output analysis based on the emergy dollar ratio to gain insight into changes in co2 emissions embodied in china us trade an input output analysis based on the emergy dollar ratio edr is used to estimate embodied co2 emissions a structural decomposition analysis sda is employed to analyze the driving factors for changes in co2 emissions embodied in china s exports to the us during 2002 2007 the results of the input output analysis show that net export of co2 emissions increased quickly from 2002 to 2005 but decreased from 2005 to 2007 these trends are due to a reduction in total co2 emission intensity a decrease in the exchange rate and small imports of embodied co2 emissions the results of the sda demonstrate that total export volume was the largest driving factor for the increase in embodied co2 emissions during 2002 2007 followed by intermediate input structure direct co2 emissions intensity had a negative effect on changes in embodied co2 emissions the results suggest that china should establish a framework for allocating emission responsibilities enhance energy efficiency and improve intermediate input structure

environmental pollution and world trade abstract in this paper we present a model that highlights the relationship between international trade and environmental pollution it includes a small open economy that produces a domestic composite good and imports another composite good and energy products the pollution is created by local production global production and transportation given this model we demonstrate that free trade within the current political and economic context may produce a suboptimal level of welfare the rationale is based upon the argument that transportation is energy intensive and that therefore trade itself is a source of pollution consequently under certain global conditions the introduction of an energy tariff in a small open economy raises social welfare and is superior to free trade a consumption tariff adopted by a single nation will not have similar consequences because it has no impact upon local usage however when a consumption tariff is globally adopted there is the opportunity for a net benefit finally we argue that a global tariff that raises both the price of energy and the price of the imported composite good may generate the greatest increase in welfare by reducing both energy intensive production and energy intensive trade

a combined input output and sensitivity analysis approach to analyse sector linkages and co2 emissions abstract this paper proposes a methodology which identifies the main productive linkages between activity branches in terms of co2 emissions and applies this methodology to the spanish case it suggests that emissions are related to the input output productive relationships within an economy to the co2 emissions intensity of sectors and to the structure of final demand of different sectors a formal analysis of these factors is carried out by means of an input output framework combined with sensitivity analysis and lineal programming the most co2 emissions intensive productive relationships in spain are shown this consideration of the main linkages contributes to the identification of the key sectors and facilitates the design of effective policy measures aimed at co2 emissions abatement

impact of inter sectoral trade on national and global co2 emissions an empirical analysis of china and us abstract this paper attempts to discuss the co2 emissions embodied in sino us international trade using a sector approach based on an input output model established in this study we quantify the impact of sino us international trade on national and global co2 emissions our initial findings reveal that in 2005 the us reduced 190 13 mt co2 emissions through the consumption of imported goods from china while increasing global co2 emissions by about 515 25 mt similarly china reduced 178 62 mt co2 emissions through the consumption of us goods while reducing global co2 emissions by 129 93 mt sino us international trade increased global co2 emissions by 385 32 mt as a whole of which the chemical fabricated metal products non metallic mineral products and transportation equipment sectors contributed an 86 71 share therefore we suggest that accelerating the adjustment of china s trade structure and export of us advanced technologies and experience related to clean production and energy efficiency to china as the way to reduce the negative impact of sino us trade on national and global co2 emissions this behavior should take into account the processing and manufacturing industries as a priority especially the chemical fabricated metal products non metallic mineral products and transportation equipment sectors

the embodied energy in trade what role does specialization play abstract many industrialized countries are net importers of embodied energy and emissions while many developing countries are net exporters we examine the role of specialization in driving these trade patterns by conducting a spatial index decomposition analysis on the embodied energy in net exports for 41 economies the results reveal that industrialized countries have generally offshored energy intensive production which many developing countries specialize in we find that specialization on average makes the biggest contribution accounting for roughly 50 of a country s embodied energy in net exports however other factors namely energy intensity and the trade balance combine to make an equally important contribution in summary specialization despite its significant role is not the only cause of the embodied energy trade patterns observed between industrialized and developing countries

china usa trade indicators for equitable and environmentally balanced resource exchange abstract trade needs to be evaluated by more comprehensive indicators that complement market based economic value the emergy accounting ema method proved to be a valuable tool to help address trade complexity by means of environmental quality oriented indicators ema is used in this paper to evaluate the environmental and resource flows involved in china united states usa trade in the years 1993 2000 and 2008 results show that china emergy exports i e exports of raw and less processed resources exceed the imports from usa although the money received by china from exports is higher than the money paid for imports the real imbalance relies in the huge amount of resources that outflow from china hardly compensated by the value of imports in terms of support to chinese economy the conclusion is that trade accounting methods should include holistic valuations beyond the financial costs of traded goods policy implications of these results are discussed

wage differentials employer size and unemployment the unique equilibrium solution to a game in which a continuum of individual employers choose permanent wage offers and a continuum of workers search by sequentially sampling from the set of offers is characterized wage dispersion is a robust outcome provided that workers search while employed as well as when unemployed the unique nondegenerate equilibrium distribution of wage offers is constructed for three cases 1 identical workers and employers 2 identical employers and an atomless distribution of worker supply prices and 3 identical workers and an atomless distribution of job productivities copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

economic structure and strategies for greenhouse gas mitigation abstract greenhouse gas ghg emission mitigation policy impacts the economic system directly in the short term by altering relative prices and indirectly in the long term by shifting the structure of the economy there may also be adjustments to economic structure independent of policy intervention due to changes in population consumption patterns and global markets the overall effectiveness of specific mitigation policy will partly depend on these indirect and exogenous changes to economic structure this study develops a new measure linking economic development with its environmental effects the technical cost of ghg mitigation under economic growth in an economy is calculated by combining traditional input output io analysis and a linear programming based sensitivity analysis the approach is applied to northern ireland ni producing an isoemission matrix that maps emission neutral expansion paths for the economy the measurement provides an indicator of the demand for technical improvement to achieve ghg mitigation at a national or regional level the flexibility and transparency of the approach make it useful for evaluating potential ghg mitigation strategies
