can we use the energy intensity indicator to study decoupling in modern economies abstract the economic energy intensity of a country defined as the ratio between the energy consumed and the gross domestic product of a country is a widely adopted indicator of economic performance often applied to sustainability analysis the usefulness of this indicator has been challenged on the basis of the fact that the two variables making up this ratio are correlated this implies that when considered in isolation each one of these two variables energy consumption p c and gdp p c maps on to typologies of socio economic systems e g developed countries vs less developed countries however calculating their ratio produces an indicator which does not map on to any meaningful typology of economic system a number without an external referent this paper checks the validity of this criticism by looking at the economic energy intensity eei of 133 countries over the period 1960 2009 two approaches are used for this task 1 an analysis at a given point in time year 2009 after excluding countries with real gdp p c

co2 emissions embodied in china s exports from 2002 to 2008 a structural decomposition analysis abstract this study examines the annual co2 emissions embodied in china s exports from 2002 to 2008 using environmental input output analysis four driving forces including emission intensity economic production structure export composition and total export volume are compared for their contributions to the increase of embodied co2 emissions using a structural decomposition analysis sda technique although offset by the decrease in emission intensity the increase of embodied co2 emissions was driven by changes of the other three factors in particular the change of the export composition was the largest driver primarily due to the increasing fraction of metal products in china s total export relevant policy implications and future research directions are discussed at the end of the paper

technology international trade and pollution from us manufacturing pollution emitted by us manufacturers declined markedly over the past several decades even as real manufacturing output increased i first show that most of the decline in us manufacturing pollution has resulted from changing production processes technology rather than changes in the mix of goods produced i then show that increased net imports of polluting goods international trade accounts for only a small portion of the pollution reductions from the changing mix of goods together these two findings demonstrate that shifting polluting industries overseas explains only a minor part less than 10 percent of the cleanup of us manufacturing jel f18 l23 l60 o30 q52 q53

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

metabolic inequality and its impact on efficient contraction and convergence of international material resource use international inequality in material use decreased between 1970 and 2000 inequality stabilized 2000 to 2010 when global growth in material use accelerated material intensity has gained importance in shaping material use inequality inequality in material intensity has increased and shapes global material use

evolutionary theorizing in economics modern economic analysis oriented toward understanding the workings of economies that make extensive use of markets came into existence with three guiding questions all central in adam smith s 1776 1937 the wealth of nations one question concerned order without any central authority guiding and commanding action how is economic activity coordinated the second question was the challenge of explaining the prevailing constellation of prices inputs and outputs what explains the price of labor and the rent of land the third question addressed the processes of economic progress or development smith and other early economists clearly were impressed by the inventiveness the energy and the growing productivity generated by the evolving market economy how to understand its dynamics the first two questions have defined continuing central concerns of the discipline of economics since they first were posed over two centuries ago when not posed in the context of an economy that is understood as in the process of developing they seem to pull the focus of theorizing toward equilibrium conditions the third question concerned with the processes driving economic progress pulls the theorizing toward an evolutionary orientation the question of economic development has waxed and waned in centrality to the discipline as has the importance of evolutionary theorizing during the first several decades of the twentieth century evolutionary thinking and language was widespread in economics but as one contrasts the economic

transfer behavior in the health and retirement study measurement and the redistribution of resources within the family recent work by a number of economists has opened a debate about the role played by intergenerational transfers using the new health and retirement study hrs we are better able to address the issues involved contrary to the current literature on bequests we do not find that parents give transfers equally to all children rather we find that in the case of inter vivos transfers respondents give greaterfinancial assistance to their less well off children than to their children with higher incomes financial transfers to elderly parents are also found to be negatively related to the potential recipient s income these results hold both for the incidence of transfers and for the amounts in addition we allow for unobserved differences across families by estimating fixed effect models and find our results to be robust to these specifications a comparison of the hrs transfer data to other survey data demonstrates that the hrs is potentially quite useful for research on transfer behavior

the multi factor energy input output model abstract energy input output analysis eio analysis is a noteworthy tool for the analysis of the role of energy in the economy however it has relied on models that provide a limited description of energy flows in the economic system and do not allow an adequate analysis of energy efficiency this paper introduces a novel energy input output model the multi factor energy input output model mf eio model which is obtained from a partitioning of a hybrid unit input output system of the economy this model improves on current models by describing the energy flows according to the processes of energy conversion and the levels of energy use in the economy it characterizes the vector of total energy output as a function of seven factors two energy efficiency indicators two characteristics of end use energy consumption and three economic features of the rest of the economy moreover it is consistent with the standard model for eio analysis i e the hybrid unit model this paper also introduces an approximate version of the mf eio model which is equivalent to the former under equal energy prices for industries and final consumers but requires less data processing the latter is composed by two linked models a model of the energy sector in physical units and a model of the rest of the economy in monetary units in conclusion the proposed modelling framework improves eio analysis and extends eio applications to the accounting for energy efficiency of the economy

intergenerational transfers and liquidity constraints a growing body of evidence indicates that liquidity constraints could affect a substantial proportion of u s consumers but little is known about why these constraints might exist an important but little explored issue is the relationship between inter vivos intergenerational transfers and liquidity constraints these transfers can ease borrowing constraints empirical transfer patterns match those predicted from a model in which transfers are allocated to liquidity constrained consumers in particular the distinction between current and permanent incomes of potential recipients is a key aspect of private transfer behavior the findings have important implications for our understanding of consumer behavior

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

team theory garbage cans and real organizations some history and prospects of economic research on decision making in organizations this essay attempts to articulate and advance a long term agenda for organizational economics the essay begins with a general discussion of four specific items on this agenda and then moves to a more specific discussion of decision making in organizations beginning with two polar opposite conceptions team theory and garbage cans and then describing several recent economic models part of the rationale for writing this essay is that this agenda has both substantive and methodological commonalities with the work of james march copyright 2003 oxford university press

emissions embodied in chinese exports taking into account the special export structure of china abstract quantification of co 2 emissions embodied in china s trade is important for an informed debate on whom to blame for the recent rise in chinese emissions or the calculation of border carbon adjustments applying input output io techniques we calculate these emissions in 1 a standard model 2 a regionally disaggregated model taking into account that export production is concentrated in more advanced and more emission efficient provinces and 3 in a model with export processing taking into account that almost half of the chinese exports rely on a large share of imported intermediates and little domestic value and emissions added we compare year 2007 emissions embodied in chinese exports in a unified framework we also report emissions embodied in chinese imports used for intermediate production of exports by combining calculations for china with data from global io models we find that both a model with 30 provinces 1730 mt co 2 and a model accounting for export processing 1630 mt yield lower chinese emissions embodied in exports compared to the standard model 1782 mt in the regional model emissions are even lower 1522 mt if interprovincial trade is not taken into account

inter vivos transfers and intergenerational exchange the surge of interest in intergenerational transfers in the past decade has sparked a debate over the motivation for them are transfers given out of altruism or part of an exchange while each motive is probably at work to some extent we know little about whether one motive predominates the question is relevant for issues concerning public income redistribution and inequality in the family but despite its importance empirical evidence about motives is scarce because of limited data we investigate a new data set the national survey of families and households which remedies many of the shortcomings of other data sets containing private transfer information we find that empirical patterns for inter vivos transfers i e transfers between living persons are more consistent with exchange than altruism

ideas and work of richard m cyert abstract richard m cyert s seminal contribution to economics is the development of behavioral theory of the firm this theory has become an important plank in the bridge from economics to management his other contributions include applications of bayesian theory to economics statistical sampling in accounting experimental economics and developing an economic theory of stragetic management

the strategic bequest motive although recent research suggests that intergenerational transfers play an important role in aggregate capital accumulation our understanding of bequest motives remains incomplete we develop a simple model of strategic bequests in which a testator influences the decisions of his beneficiaries by holding wealth in bequeathable forms and by conditioning the division of bequests on the beneficiaries actions the model generates falsifiable empirical predictions that are inconsistent with other theories of intergenerational transfers we present econometric and other evidence that strongly suggests that bequests are often used as compensation for services rendered by beneficiaries

shaping intergenerational relationships the demonstration effect abstract according to the demonstration effect theory parents make intergenerational transfers to their elders in order to elicit a symmetric future behavior from their children in this paper we show that upstream transfers are expected to increase with low returns from alternative financial assets and with the donor s life expectancy the latter effect creates a greater incentive for daughters to care for parents

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

an economic analysis of midwestern us criteria pollutant emissions trends from 1970 to 2000 abstract from 1970 to 2000 u s economic output doubled but emissions of four criteria pollutants from economic activity co no x voc and so 2 decreased by 20 understanding what factors have contributed to this pollution reduction in the u s as a whole as well as in various regions within the country has important policy implications a recently developed regional environmental econometric input output model for the midwestern states of the u s has been used to examine the causes of pollution reduction in this regional economy over a thirty year period simulations conducted with this model suggest that for the rate of growth experienced over the period technological improvement has dominated economic structural change in the reduction of pollutant emissions on average technological improvement has accounted for approximately 80 of emissions reduction while economic structural change explains the remaining 20 of the decrease our analysis suggests that while much remains to be done in reducing emissions in both developed and developing countries policies that are informed by an understanding of the role of structural change and which promote the adoption of more recently developed technologies may contribute substantially to sustainable development

linking namea and input output for consumption vs production perspective analyses evidence on emission efficiency and aggregation biases using the italian and spanish environmental accounts we integrate input output and namea tables for spain and italy in 1995 2000 and 2005 in order to address the hot policy issue of sustainable consumption and production a comparison of production and consumption perspectives may have relevant policy implications we deal with the domestic technology assumption and primarily the aggregation bias that may result when calculating indirect emission using different sector aggregations in the analyses e g 16 30 50 extended input output analysis provides analyses of the emissions embodied in domestic consumption and domestic production by considering the structure of intermediate inputs and environmental efficiency in each production sector our empirical findings show that different sectoral aggregation significantly biases the amount of emissions for the consumption perspective though differently in the two countries italy surprisingly show consumption production ratios around or lower than one but in line with some major work at eu level our results thus suggest that special attention must be paid when interpreting the ee ioa of country estimated amounts of embodied emissions both in domestic final demand and those directly associated with the production sectors when the sectoral aggregation level has a low definition as considered in some recent similar studies

a reexamination of the strategic bequest motive this paper investigates the strength of the empirical evidence of the strategic bequest hypothesis proposed by bernheim shleifer and summers 1985 at issue is whether bequests are primarily motivated by a desire to influnce the behavior of potential beneficiaries alternatively bequests may be motivated by altruism or risk aversion in the presence of incomplete annuity and health insurnace markets e g tomes 1981 hurd 1989

a review of recent multi region input output models used for consumption based emission and resource accounting abstract the interest in consumption based emission and resource accounting has grown significantly many studies juxtapose consumer emissions carbon footprint and producer territorial emissions of greenhouse gases in order to demonstrate the effects of trade on the national emission budget to this end a respectable number of studies have been undertaken worldwide in order to estimate emissions embedded in international trade of numerous countries and world regions input output approaches and increasingly multi region input output mrio models are commonly chosen as they provide an appropriate methodological framework for complete carbon footprint estimates at the national and supra national level with increasing processing capabilities of computers and a wider availability of economic accounts environmental accounts and trade data such models are now being implemented on a wide scale after a brief overview of salient single region input output studies i provide an in depth review of the most recent multi region input output models used for the purpose of consumption based environmental accounting the main methodological features and important results are described for around twenty studies covering the years 2007 to 2009 this is followed by a detailed review of studies dealing with uncertainty in mrio analysis an area which has not received a lot of attention so far i conclude that further research is mainly needed in two areas a improvements in data availability and quality and b improvements in the accuracy of mrio modelling

material flows and economic models an analytical comparison of sfa lca and partial equilibrium models abstract the growing concern for environmental problems in the current economy has spurred the study of the way materials and substances flow through the economy resulting in many different types of analysis since all of these have their merits and shortcomings much of the present theoretical research seems to be focusing on combining the best aspects of each model type into an integrated model the aim of this paper is to make a first step in bridging the gap between the various types of analysis of material flows in the economy by discussing the main differences and similarities of three often employed model types substance flow analysis life cycle assessment and partial economic equilibrium analysis instead of submitting each model to a lengthy theoretical discussion we apply them to a single hypothetical example of a pollution problem by doing so we are able to evaluate the differences and similarities of the methods and results of the model in a practical way it appears that the results of the three models are complementary rather than contradictory each of them puts an emphasis on different aspects of the real world a sequential application of a number of limited models may therefore be an approach that provides more useful information than the tedious construction and application of an encompassing model that integrates these models

comparing structural decomposition analysis and index to analyze and understand historical changes in economic environmental employment or other socio economic indicators it is useful to assess the driving forces or determinants that underlie these changes two techniques for decomposing indicator changes at the sector level are structural decomposition analysis sda and index decomposition analysis ida for example sda and ida have been used to analyze changes in indicators such as energy use co2 emissions labor demand and value added the changes in these variables are decomposed into determinants such as technological demand and structural effects sda uses information from input output tables while ida uses aggregate data at the sector level the two methods have developed quite independently which has resulted in each method being characterized by specific unique techniques and approaches this paper has three aims first the similarities and differences between the two approaches are summarized second the possibility of transferring specific techniques and indices is explored finally a numerical example is used to illustrate differences between the two approaches

an input output framework for analysing energy consumption abstract the paper develops an input output framework for measuring the direct indirect and income induced energy effect of a change in final demand and for estimating the effect of technical change on energy consumption

economic growth and the evolution of water consumption in spain a structural decomposition analysis abstract the aim of this paper is to examine how technology processes of input substitution and changes in final demand all of which underlie economic growth influence water consumption this analysis is undertaken for spain during a significant socio economic period from 1980 the beginning of the democratic era to 2007 the onset of the current economic crisis to this end we construct water consumption series linked to a time series of input output tables generated for the spanish economy and we develop a structural decomposition analysis to study mainly changes in water consumption embodied in final demand we find that the growth in spanish demand all other things being constant would have implied an increase in water consumption almost three times the growth actually observed however this demand effect is largely offset by technology and intensity effects mainly due to changes in agricultural crops given the importance of the demand growth the final demand effect is also analyzed in detail broken down by categories as well as level and composition household demand and the increase of exports appear as key explicative factors

looking backward to look forward water use and economic growth from a long term perspective recent research has examined the relationship between natural resources and economic growth considered vitally important not only for humanity s well being but also for the integrity of the ecosystem the relationship between water use and economic growth has nevertheless traditionally attracted little attention by analysts this article studies water use trends from 1900 to 2000 throughout the world and their relationship to the main determinants of economic growth to do this we first analyse water use trajectories second to proceed with the determinants of water use we reformulate the ehrlich and holdren s impact population affluence technology ipat equation 1971 decomposing water use trends into changes in economic demands and in water use intensity on the basis of a decomposition analysis finally a simple scenario analysis is conducted to project future water use trends under different economic demographic and technological assumptions the empirical evidence shows that economic and

analysis of electricity consumption in china 1990 2016 using index decomposition and decoupling approach abstract electricity consumption accounts for a significant portion of final energy consumption in countries worldwide and has a close relationship with economic growth this paper explores the factors influencing electricity consumption in china during 1990 2016 using index decomposition analysis and analyses the decoupling status between economic growth and electricity consumption in addition to the influencing factors these analyses are conducted at both national and sectoral levels the results reveal that 1 the economic activity effect was the main driving force increasing total electricity consumption in china while the energy intensity effect hindered it 2 both diversity and aggregation existed at the sector level the power generation chemicals and non ferrous sectors were the top three contributors to increased electricity consumption 3 the change of electricity consumption caused by gdp growth in china showed three decoupling states during 1990 2016 expansive negative decoupling expansive coupling and weak decoupling in particular the energy intensity effect stimulated the occurrence of decoupling 4 industrial sectors played a significant role in decoupling in china while service sectoral electricity consumption showed expansive coupling with its sectoral gdp in recent years

readjustment potentials in industrial energy efficiency and structure abstract with the availability of input output data for 1977 it is possible to analyze the short run effects of the 1974 energy price increase as well as other factors on the energy efficiency of the industries of the economy such an analysis is conducted here using a number of measures derived through the energy input output model attention is focused on patterns of energy use changes in energy intensities through time and the factors which underlie these changes a specific measure of the degree to which energy substitution is attributable to changes in direct and indirect energy requirements is developed and estimated results show that large changes in the economy s overall industrial energy requirements are not observed between 1963 and 1977 however for individual fuels large changes in intensity values are not at all uncommon among industries

economic social and environmental impacts of fuel subsidies a revisit of malaysia abstract subsidizing energy has been widely used but is economically unfavorable the malaysian government has shown strong intention to reduce energy subsidies recently but face challenges to prepare policy instruments to manage the impact this study develops a computable general equilibrium cge model with breakdown of households by income level to evaluate the potential impacts of removing energy subsidies on the malaysian economy it is shown that removing petroleum and gas subsidy would improve economic efficiency and increase gdp up to 0 65 budget deficit would be largely reduced after removing the petroleum subsidies especially when the saved subsidy cost is not budgeted for other expenditure households would be worse off in most scenarios due to higher price level but some compensation policy could make the lowest income group no worse than baseline without harm the economy the reduction in carbon emissions ranges 1 84 6 63 in different scenarios the simulation results suggest malaysia to completely remove all fuel subsidies and use the saved funding to cut budget deficit or spend on education health and other service sector it is also necessary to set a compensation scheme to minimize public resistance and make sure such scheme is affordable

measuring structural change and energy use decomposition of the us economy from 1997 to 2002 abstract the steadily increasing focus on energy production and consumption has led to growing research attention to patterns of energy use within economies of particular interest has been comparing the driving forces of increasing efficiency and economic structural change input output analysis ioa and decomposition analysis have become critical tools for performing such analyses this study analyzes aggregate energy use in the united states in 1997 and 2002 to discover the causes of changing energy usage and flows results show that rising population and household consumption acted to drive up energy demand but this driving force was offset by considerable structural change within the economy particularly related to a quickly increasing trade deficit in manufacturing goods thus while total energy intensity the ratio of energy use to economic output declined by approximately 12 between 1997 and 2002 changes in the structure of the economy explain this drop more than increased energy efficiency the level of aggregation at which decomposition analyses are run was identified as a crucially sensitive parameter for the determination of structural change and future studies should specifically address the amount of detail necessary to adequately measure changes in economic structure

consumer and producer environmental responsibility comparing two approaches abstract two different indicators of environmental responsibility were independently proposed by rodrigues et al rodrigues j domingos t giljum s schneider f 2006 designing an indicator of environmental responsibility ecological economics 59 3 256 266 and lenzen et al lenzen m murray j sack f wiedmann t 2007 shared producer and consumer responsibility theory and practice ecological economics 61 27 42 these indicators are both supposed to reflect the indirect effects of consumer and producer behavior in the generation of environmental pressure in this paper we compare their mathematical properties and interpretation we conclude that they have different implications for environmental policy

economic drivers of greenhouse gas emissions in china abstract for china greenhouse gas emissions increased by 0 075 gigatons gt in the period of 1995 2000 and increased by 4 23 gt from 2000 to 2009 then reached the amount of 8 61 gt in 2009 different from the traditional analysis focused on accounting sectors greenhouse gas emissions under the production based responsibility this paper investigates sectoral ghg emissions in china in the period of 1995 2009 from the perspective of consumption based and income based responsibility we found that different metrics yield very different ghg emission responsibilities the sector of electricity gas and water supply has the highest ghg emissions responsibility based on the production and income metrics while the sector of construction is the largest emitter under the consumption metric in the light of the key driver analysis of ghg emissions from 1995 to 2009 based on the consumption metric the change in the final demand volume is the largest driver of increase in china s consumption based ghg emissions 17 18 gt the changes in the production structure and the final demand structure are other contributors 0 53 gt 1 46 gt the improvement to the intensity of ghg emissions is the main force for ghg emissions mitigation 14 86 gt according to the income metric the contributions of input volume changes input structure changes and ghg intensity changes are similar to the effects of consumption based responsibility 19 11 gt 1 13 gt 14 95 gt the difference is that the change in the production structure is another force that offset ghg increase 0 98 gt results in this paper can give some recommendation on mitigating ghg emissions in china for policy makers from production side demand side and supply side

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 simulations of energy environment economy interactions in the uk this paper shows how a number of the complex interrelationships between energy environment and economic welfare can be investigated with the aid of a 10 sector input output i o model of the uk with pollution emission coefficients and a european sulphur deposition vector the paper reviews relevant past applications of i o analysis in the energy environment area and describes the endam program and its operation it is used to simulate the effects of a variety of policies and possibilities not only through changes in exogenous variables final demand and income taxes and transfers but also through changes in the structural matrices and their coefficients in each case the full effects direct indirect and income induced can be traced and the changes in comparative static equilibrium values discovered in this way policy issues connected with energy use and environmental impacts employment and economic welfare have been investigated

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

accounting for nitrogen in denmark a structural decomposition analysis abstract this paper examines the environmental economic cycle for nitrogen in denmark based on nitrogen input and output from different economic sectors an input output model is employed together with a nitrogen mass balance to apportion total nitrogen loading by final demand and estimate export and import of nitrogen from foreign trade the changes in agricultural and industrial nitrogen loading from the mid 1960s to the late 1980s are broken down into changes related to different technological and economic factors the analysis reveals that technological change intensified agricultural production and economic growth especially rising exports are the key factors structural shifts changes in commodity mix in the household and production sectors generally being of less importance

residential energy consumption in urban china a decomposition analysis abstract residential energy consumption rec is the second largest energy use category 10 in china and urban residents account for 63 of the rec understanding the underlying drivers of variations of urban rec thus helps to identify challenges and opportunities and provide advices for future policy measures this paper applies the lmdi method to a decomposition of china s urban rec during the period of 1998 2007 at disaggregated product activity level using data collected from a wide range of sources our results have shown an extensive structure change towards a more energy intensive household consumption structure as well as an intensive structure change towards high quality and cleaner energy such as electricity oil and natural gas which reflects a changing lifestyle and consumption mode in pursuit of a higher level of comfort convenience and environmental protection we have also found that china s price reforms in the energy sector have contributed to a reduction of rec while scale factors including increased urban population and income levels have played a key role in the rapid growth of rec we suggest that further deregulation in energy prices and regulatory as well as voluntary energy efficiency and conservation policies in the residential sector should be promoted

an overview of the driving forces behind energy demand in china s construction industry evidence from 1990 to 2012 abstract the rapid urbanization in china has produced a large demand for energy in the past decades it is therefore urgent to have an understanding of the driving forces behind the energy increase in the construction industry this study applies structural decomposition analysis sda to quantify the effects of driving factors from insight into consumption and production the results show that the energy consumption trajectory of china s construction industry is the result of competition between the effect of increasing final demand and improvement in energy efficiency although the effect of consistent efforts in structure optimization by the central government was significant from 2007 to 2012 the potential to save much energy still lies in structure optimization in energy production and final demand according to the projection structural upgrades in economy would be the most important factor for energy reduction in 2020 scenario analysis further indicated that the percentage change of energy increments in 2020 can be reduced at 22 of 2010 level under the optimistic scenario sector aggregation analysis revealed that more aggregates would increase uncertainty to some extent and result in a misinterpretation of the importance of the underlying factors according to the quantitative analysis in this study the percentage change of total embodied energy consumption in the construction industry should be limited below 25 of 2010 level at the end of the 13th five year plan

the supply of children s time to disabled elderly parents i introduction in recent years economists have become increasingly interested in intergenerational transfers of both time and money 1 such transfers may be motivated by altruism or exchange models of altruism assume that a person s utility depends on the consumption or utility of other family members and her own consumption for example children may supply unpaid informal care to aging parents because their utility increases when their parents are happier one of the most striking predictions of models of altruism is that public subsidies tend to crowd out transfers by altruistic individuals especially if the subsidy is financed by taxing the altruistic individual becker 1974 in exchange models there is typically altruism but one family member such as a parent can induce a relative such as a child or kid 2 to provide more services or money than the relative would normally provide by threatening to withhold a bequest to the extent that this is so one would plausibly expect more care and attention to be provided to wealthy parents when there is more than one kid more care should be provided because the threat of disinheritance is more credible when there is competition between kids for bequests in a well known article bernheim shleifer and summers 1985 hereafter referred to as bss found empirical support for the strategic bequest motive based on an observed positive relationship between children s visits and telephone calls to elderly parents per child as the measure of attention and bequeathable wealth per child as the measure of the financial motivation for providing such attention one might expect this result to extend to decisions about direct provision of help informal care that kids may provide to parents the marginal benefit of such care is plausibly greater than the benefit derived from a visit or telephone call in a recent article however we found no evidence that the strategic bequest motive is an important determinant of the amount of informal care kids provide or a related decision whether or not to place the parent in a nursing home sloan hoerger and picone 1996 we focused on the distinction between cognitively aware parents who can threaten to disinherit their kids and cognitively unaware parents who cannot disinherit and examined whether this distinction had any effect on the probability that the parent entered a nursing home or on amounts of formal and informal care received if the parent remained in the community any strategic effects were swamped by the greater marginal benefit of care to the parent when the parent was cognitively unaware moreover among the cognitively aware richer parents actually received less informal care contrary to the strategic model s predictions unfortunately in past research on intergenerational transfers of time and money it was not possible to control for the wealth wage and other characteristics of kids to the extent that kid s wealth and wage were positively correlated with parent s wealth which was observed the parameter estimates on parent s wealth may be negatively biased although parent s wealth and kid s wealth and wage rates are plausibly positively correlated they have opposite effects on the supply of kid s time according to the strategic bequest model that is potential bequests from a parent may be less attractive to rich kids and therefore induce less care we test the strategic bequest model using information on elderly parents and their children from two linked surveys the 1989 national long term care survey nltcs for elderly individuals and the survey of informal caregivers sic for a subsample of the elderly s children using these data we can include explicit measures of kid s wealth and wage rates thereby avoiding the possible bias introduced by a correlation between parent s and kid s wealth and wages also the data sets provide information on several pertinent health cognitive and functional status variables which are not typically observed in surveys of financial status

the effect of trade between china and the uk on national and global carbon dioxide emissions we estimate the amount of carbon dioxide embodied in bi lateral trade between the uk and china in 2004 developing and applying the method of shui and harriss 2006 tile role of co2 embodiment in us china trade energy policy 34 4063 4068 the most recently available data on trade and co2 emissions have been updated and adjusted to calculate the co2 emissions embodied in the commodities traded between china and the uk it was found that through trade with china the uk reduced its co2 emissions by approximately 11 in 2004 compared with a non trade scenario in which the same type and volume of goods are produced in the uk in addition due to the greater carbon intensity and relatively less efficient production processes of chinese industry china uk trade resulted in an additional 117 mt of co2 to global co2 emissions in the same one year period compared with a non trade scenario in which the same type and volume of goods are produced in the uk this represents an additional 19 to the reported national co2 emissions of the uk 555 mt y in 2004 and 0 4 of global emissions these findings suggest that through international trade very significant environmental impacts can be shifted front one country to another and that international trade can but does not necessarily result in globally increased greenhouse gas emissions these results are additional to the environmental consequences of transporting goods which are not robustly quantified here c 2008 elsevier ltd all rights reserved

changes in industrial electricity consumption in china from 1998 to 2007 abstract electricity consumption in the industrial sector experienced a dramatic increase between 1998 and 2007 accounting for approximately 75 of china s total electricity consumption this study analyzes the potential factors influencing the growth of electricity consumption in china s industrial sector over the past decade using a logarithmic mean divisia index i decomposition method results show that activity effect and shift effect caused by the change in the electricity s share of industrial energy use are the major factors responsible for the rise in electricity consumption between 1998 and 2007 it is found that structural change also contributed to the increase in electricity consumption it had only a small effect in contrast the technological effect is responsible for a decrease in electricity consumption during this period the influences of technological effects and shift effects followed approximately an inverse u shaped and u shaped curve respectively furthermore the results show that the main contributors to incremental electricity consumption among industrial subsectors were manufacturing of raw chemical material and products manufacturing of non metal mineral products smelting and pressing of ferrous and non ferrous metals and production and supply of electric power and heat power these sectors should take priority for industrial restructuring in order to implement policies for energy and electricity savings

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

global warming agreements international trade and energy carbon embodiments an input output approach to the italian case abstract in the kyoto protocol the absence of green house gases ghgs commitments of developing countries non annex i and the more flexible terms of implementation which are allowed to countries shifting toward a market economy transition economies naturally lead to the absence or to less constraining national measures and policies of reduction of the ghgs emissions which in turn may determine a comparative advantage in the production of the highest energy carbon intensive commodities for these countries these arguments are valid also considering the future implementation of the european emission allowance trading scheme eats thus developing countries may become a haven for the production of not environmental friendly commodities in this case the so called pollution haven hypothesis stating that due to freer international trade the comparative advantage may change the economic structure and consequently the trade patterns of the countries linked by trade relationships could occur this would lead to the increase of the transfers of energy and carbon embodied in traded commodities from developing countries and transition economies toward kyoto or eats constrained countries the aim of this paper is to verify if for italy as a kyoto and eats complying country evidence of a change in the trade patterns occurred on the basis of the pollution haven hypothesis does exist and to estimate the magnitude of the under estimation of the carbon actually emitted the carbon leakage the input output model has been used to calculate the intensities of energy consumption and the related green house gases emission for each italian economic sector

intra family transfers in japan intergenerational co residence distance and contact classified broadly two motives for intra family transfers exist altruism and selfishness this paper examines two selfish hypotheses the exchange motive strategic bequest motive and the demonstration effect using a new japanese microdata set analysis of the determinants of intergenerational co residence distance between residences and frequency of contact yields considerable support for the exchange motive but no support for the demonstration effect the findings are consistent with the exchange motive after distinguishing it from mutual altruism

is energy efficiency a driver or an inhibitor of energy consumption changes in spain two decomposition approaches abstract the 2000 2008 expansion period of the economy was accompanied by an important increase of energy consumption the desire of decoupling has led us to analyse the driving forces behind the energy consumption changes during this expansion period through a structural decomposition analysis sda based on the spanish input output tables previous decomposition has been supplemented by a logarithmic mean divisia index lmdi analysis of the energy consumption changes during a longer period 2000 2013 the results show that the energy intensity was the main inhibitor effect of the energy consumption changes of sectors of production not only during the recession but also during the expansion period secondly the energy intensity was a driver of the energy consumption change of households during the expansion period however during the recession period the energy intensity of private transport contributed to reducing energy consumption having an inhibitor effect therefore if the activity effect is still the most important driver the energy intensity effect has become the main inhibitor of energy consumption changes the energy policy recommendation is to focus on household energy consumption in the future if the spanish government aims to attain the eu energy efficiency objectives

private intergenerational contact in france and the demonstration effect this study analyses motives for intergenerational contact from adult children to their middle aged parents if these transfers may be explained either by altruism or by exchange we mainly focus on the demonstration effect where households take care of their own parents in order to elicit a future support from their children we test the model using a cross sectional survey from 1992 about private transfers in france according to the data the presence of children increases the amount of visits that respondents provide to their parents and the econometric results still hold after controlling for unobserved familial heterogeneity using fixed effects although this empirical evidence is consistent with the demonstration effect we suggest an alternative interpretation for the positive correlation based on the care of grandchildren

decomposition of co2 emissions over 1980 2003 in turkey abstract there is a multi dimensional need for studying the energy situation in turkey and to obtain insight into the development of co2 emissions on the one hand recent projections of the oecd show that turkey has a yearly gdp growth potential of over 7 on the other hand recent projections of undp and world bank indicate that the level of co2 emission is going to rise six fold by 2025 with respect to the level of emissions in 1990 it is a great challenge to both meet the growth target and keep the co2 under control thereupon this paper tries to unfold factors that explain co2 emissions by undertaking a complete decomposition analysis for turkey over the period 1980 2003 the analysis shows as is common to relatively fast growing economies that the biggest contributor to the rise in co2 emissions is the expansion of the economy scale effect the carbon intensity and the change in composition of the economy which nearly move in tandem also contribute to the rise in co2 emissions albeit at a slower rate the energy intensity of the economy which is decreasing is responsible for a modest reduction in co2 emissions hence in congruence with the scale effect a decoupling of carbon emissions and economic growth is not found in turkey over the period 1980 2003

an interindustry analysis of structural change and energy use linkages in the saskatchewan economy abstract the impacts of changes in final demand on energy use are analysed through the use of a combined energy use input output model of the province of saskatchewan through the use of various index measures the energy interdependence of the provincial economy is examined for the 1974 1979 period key sectors are identified whose final demand result in relatively large increases in provincial energy use the model is extended to analyse the interaction of changes in final demand on energy use the level of household income and employment

how does the implementation of the policy of electricity substitution influence green economic growth in china abstract to promote the level of electrification reduce environmental pollution and achieve the goal of clean energy usage and green economic growth in china the national development and reform commission and other eight departments jointly issued and implemented the policy of electricity substitution in 2016 electricity substitution aims to replace traditional fossil fuels such as coal and fuel oil with clean electric energy in different fields e g industry transportation and construction and deal with the pollutants at power generation however we still need to find out the exact impact of the policy of electricity substitution on energy saving and emission reduction in this paper we estimate the economically feasible increment of electricity demand according to different classifications in electricity substitution technology furthermore based on the input output model we discuss the relative influence of the policy of lectricity substitution the main conclusions are first the policy of electricity substitution alone is not adequate to reduce the dependence on fossil energy and environmental pollution under china s current power generation structure we should also increase the use of renewable energy second the power sector plays a leading role in stimulating economic output and the increasing electricity consumption due to the policy of electricity substitution can boost the green development of china s economy

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

motives for private income transfers private income transfers are becoming increasingly recognized as a key aspect of the u s economy the majority of private income transfers occur inter vivos i e between living persons but very little is known about this type of transfer behavior this paper tests alternative hypotheses concerning motivation for inter vivos transfers two motives are considered altruism and exchange evidence presented here casts doubt on the altruistic model of transfer behavior observed patterns for inter vivos transfers are more consistent with exchange related motives this finding has important implications for the effects of public transfer programs on the distribution of economic well being

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

revisiting drivers of energy intensity in china during 1997 2007 a structural decomposition analysis the decline of china s energy intensity slowed since 2000 during 2002 2005 it actually increased reversing the long term trend therefore it is important to identify drivers of the fluctuation of energy intensity we use input output structural decomposition analysis to investigate the contributions of changes in energy mix sectoral energy efficiency production structure final demand structure and final demand category composition to china s energy intensity fluctuation during 1997 2007 we include household energy consumption in the study by closing the input output model with respect to households results show that sectoral energy efficiency improvements contribute the most to the energy intensity decline during 1997 2007 the increase in china s energy intensity during 2002 2007 is instead explained by changes in final demand composition and production structure changes in final demand composition are mainly due to increasing share of exports while changes in production structure mainly arise from the shift of chinese economy to more energy intensive industries changes in energy mix and final demand structure contribute little to china s energy intensity fluctuation from the consumption perspective growing exports of energy intensive products and increasing infrastructure demands explain the majority of energy intensity increase during 2002 2007

a three perspective view of greenhouse gas emission responsibilities in new zealand abstract while responsibility for the environmental impacts of production has been commonly assigned to producers production is driven by consumer demand and it is valid to question whether impacts should instead be assigned to consumers however in each of these approaches producers and consumers either bear the full burden of responsibility or none at all an example of this is the kyoto protocol where all greenhouse gas emissions are assigned to the producer and no consideration is given to where goods are finally consumed rather than taking the conventional producer or consumer responsibility approach a third perspective is possible in which responsibility is shared we use input output analysis to apply all three of these responsibility perspectives to new zealand s domestic greenhouse gas emissions our main findings from the shared responsibility approach are that new zealand producers are responsible for 44 of domestic emissions new zealand consumers take 28 and 27 are exported a shared responsibility approach appears to distribute the burden of responsibility and associated liability between parties more fairly and is likely to be more widely acceptable than pure producer or consumer perspectives

on the demand for grandchildren tied transfers and the demonstration effect it is argued that parents provide help with housing downpayments in order to encourage the production of grandchildren and that such a subsidization emanates from the bdemonstration effect q a child s propensity to furnish parents with attention and care can be conditioned by parental example parents who desire such transfers in the future have an incentive to make transfers to their own parents in order to instill appropriate preferences in their children this generates a derived demand for grandchildren since potential grandparents will be treated better by their adult children if the latter have their own children to whom to demonstrate the appropriate behavior empirical work indicates behavior consistent with subsidization of the production of grandchildren and the demonstration effect

parental altruism and inter vivos transfers theory and evidence this paper uses psid data on the extended family to test whether inter vivos transfers from parents to children are motivated by altruism specifically the paper tests whether an increase by one dollar in the income of parents actively making transfers to a child coupled with a one dollar reduction in that child s income results in the parents increasing their transfer to the child by one dollar this restriction on parental and child transfer income derivatives is derived for the standard altruism model augmented to include uncertainty and liquidity constraints these additional elements pin down the timing of inter vivos transfers the method used to estimate income transfer derivatives takes into account unobserved heterogeneity across families in the degree of altruism the findings strongly reject the altruism hypothesis redistributing one dollar from a recipient child to donor parents leads to less than a 13 cent increase in the parents transfer to the child far less than the one dollar increas

bi lateral co2 emissions embodied in australia china trade abstract this paper quantifies the co 2 emissions embodied in bi lateral trade between australia and china using a sectoral input output model the results revealed 1 that china performs lower than australia in clean technology in the primary manufacturing energy sectors due to their overuse of coal and inefficient sectoral production processes and 2 that china had a 30 94 mt surplus of bi lateral co 2 emissions in 2010 2011 and 3 overall global emissions were reduced by 20 19 mt through australia china trade in 2010 2011 the result indicates that the greater the energy efficient a country among the trading partners the lower will be the overall global co 2 emissions global emissions decreased mainly because china consumed australian primary products rather than producing them australia is an energy efficient producer of primary products relative to china the bilateral trade compositions and trade volume played an important role in lowering global emissions and therefore one can view proposed china australia free trade agreement positively in reducing global emissions however for the sustainable development china should strengthen clean energy use and both countries should adopt measures to create an emission trading scheme in order to avoid protectionism in the form of future border price adjustments

input output and structural decomposition analysis of singapore s carbon emissions singapore is an island city state it lacks conventional energy resources and is alternative energy disadvantaged in the past decade 2000 2010 its energy related carbon emissions increased from 37 8 to 44 4 million tonnes of co2 this paper analyses the city state s carbon emissions from the demand perspective using the input output i o method and investigate the drivers of emission changes using structural decomposition analysis sda it is the first comprehensive analysis of singapore s emissions using the i o framework the results obtained show that exports accounted for nearly two thirds of its total emissions and growth in its emissions in the last decade was largely export driven emissions increased as export oriented industries and export volume expanded fuel switching and energy efficiency however helped to lower growth in emissions besides exports household related emissions accounted for about a quarter of singapore s total emissions the emissions related to different household groups remained fairly stable as increases in embodied indirect emissions were offset by decreases in direct emissions the high income household group registered the largest increase in direct emissions while the middle income household group registered the largest increase in embodied emissions the policy implications of our findings are discussed

transaction cost economics and the carnegie connection abstract this paper tracks my remarks at the september 1993 conference honoring richard m cyert it begins with some recollections of my years as a graduate student at gsia in the early 1960s i then shift to transaction cost economics and how this project relates to what i learned from dick cyert and others at carnegie

carbon dioxide emissions in the u s economy a structural decomposition analysis this paper provides an empirical analysis of the impact of various influences on carbon dioxide emissions it incorporates methodological refinements of input output structural decomposition analysis which is the examination of economic change by means of a set of comparative static variations in key parameters of i o tables the analysis is performed using a two tiered klem model which allows for estimation of substitution and technological change effects within and between input aggregates the model is used to decompose the sources of change in co2 emissions in the u s over the 1972 82 timeframe using hybrid energy value tables for the initial and terminal years results show the significant effect of substitution within the energy sector and between energy and other inputs as the leading causes of the decline in carbon dioxide emissions

the co2 trade balance between scotland and the rest of the uk performing a multi region environmental input output analysis with limited data in this paper we attempt an empirical application of the multi region input output mrio method proposed by turner lenzen wiedmann and barrett turner k lenzen m wiedmann t barrett j 2007 examining the global environmental impact of regional consumption activities part 1 a technical note on combining input output and ecological footprint analysis ecological economics 62 1 37 44 in a recent issue of this journal in order to enumerate the co2 pollution content of interregional trade flows between scotland and the rest of the uk ruk we extend the analysis to account for direct emissions generation by households as final consumers and to a social accounting matrix sam where a more comprehensive account of incomes and expenditures is possible while the existence of significant data problems mean that the quantitative results of this study should be regarded as provisional the interregional economy environment io and sam framework for scotland and ruk allows an illustrative analysis of some very important issues in terms of the nature and significance of interregional environmental spillovers within the uk and the existence of a co2 trade balance between scotland and ruk

imbalance of carbon emissions embodied in the us japan trade temporal change and driving factors abstract in us japan trade japan ran both economic export surplus and export co2 emission surplus with the us positive net monetary exports for japan were actually a kind of economic losses of the us while positive net export co2 emissions or net co2 emissions embodied in us japan trade were regarded as pollution transfer from u s to japan however due to lack of unified measurement units and standards between the two research fields it is difficult to directly assess whether positive effects of u s via carbon transfer outweigh negative effects caused by economic losses the study transforms absolute values of net monetary exports and net export co2 emissions from 2000 to 2011 in us japan trade into two ratios the ratio of net monetary exports to gdp of u s and the ratio of net embodied co2 emissions to total co2 emissions of the us by comparison the result shows that on average net monetary exports between u s and japan accounted for 0 45 of american gdp while ratio of net export emissions to aggregate consumption based co2 emissions of u s kept about 0 20 during the research period concerned which indicated that negative effects of economic losses in u s outweighed positive effects via carbon transfer in us japan trade furthermore a structural analysis of co2 emissions embodied in us japan trade during the 11 years is given the most significant driver was emission coefficients defined as co2 emissions per unit of energy consumption the driving force of emission coefficients led to dramatic reduction in co2 flows from japan to the us and thus caused decrease of net export emissions which also explained the major reason for the low ratio of export emissions to total co2 emissions of the us finally according to sectoral distributions of co2 flows between japan and the us emission sources of two countries presented different characteristics

sources of change in industrial electricity use in the taiwan economy 1976 1986 abstract this paper applies an input output structural decomposition model in order to analyse the sources of change in the 1976 to 1986 electricity demands of the industrial sectors in taiwan various types of demand shifts technical substitutions and technological changes are identified the relative importance of 14 mutually exclusive sources of change is evaluated the results indicate that over the course of the study period while economic growth had the dominant impact on electricity use followed in importance by substitution effects effects due to technological change had an adverse effect being much weaker than those resulting from economic growth and substitution effects it is expected that this pattern will remain unchanged in the foreseeable future hence industrial electricity demand in taiwan will continue to grow

the carbon content of japan us trade we analyze the greenhouse gas emissions embodied in trade between japan and the us extending the japanese government s linked japan us input output model to include carbon emission coefficients for each sector we estimate that in 1995 japan us trade reduced us industrial emissions by 14 6 million tons of co2 equivalent and increased emissions in japan by 6 7 million tons for a global savings of 7 9 million tons these quantities are less than one percent of each country s total emissions trade with the rest of the world reduced emissions by much larger amounts roughly four percent of each country s emissions the sectoral patterns of carbon intensity are strongly correlated between japan and the us in addition greater carbon intensity has a small but significantly positive effect on net exports policies that tax or otherwise regulate carbon emissions are needed to discourage this destructive route to competitiveness however the most important policy implication may be that us industry could cut its carbon emissions by more than half if it matched the environmental performance of industry in japan r 2007 elsevier ltd all rights reserved

how altruism can prevail in an evolutionary environment abstract we study environments in which an individual gets a higher payoff from defecting than from cooperating and where copies of an individual are more likely to appear the higher is the individual s payoff we demonstrate that even in single shot prisoner s dilemma models where cooperation benefits one s opponent at a cost to oneself evolution can sustain cooperative behavior between relatives or neighbors in addition we show that selfish individuals who conciously choose their actions may find it in their interest to be altruistic when there is some probability that their practices will be imitated both genetic and cultural inheritance appear to be blunt instruments that do not operate on individuals in isolation those who inherit a genetic tendency to cooperate are more likely than others to enjoy the benefits of cooperative siblings similarly with culturel inheritance altruism can prevail when individuals are likely to interact with others who share the same role model

what causes the change in energy demand in the economy the role of technological change this paper proposes a simple and theoretically clear approach to the estimation of technological change in a multisector general equilibrium framework this study employs the multiple calibration decomposition analysis mcda to evaluate technological change that is responsible for changes in energy use and carbon dioxide emissions in the japanese economy in the oil crises period from 1970 to 1985 the mcda serves as an elementary way of separating structural change due to technological change from that due to price substitution effects capturing the interdependence among economic sectors the empirical result provides a better understanding of the effects on the economy of technological change in that significant period

gray water and environmental externalities international patterns of water pollution through a structural decomposition analysis abstract despite regulatory measures restricting industrial and agricultural operations from pouring pollutants into lakes streams and rivers around 1 1 trillion m3 of wastewater were still disposed in waterways around the world in 2009 and this amount continues to grow several studies have analyzed the determinants of gray water increase at local level but so far none has explored them in an international context to highlight the role of global value added chains and the dichotomy between developed and developing nations in order to provide insights on the dynamics of water pollution worldwide this paper analyzes the main drivers of gray water discharge during the 1995 2009 period and the effort on reducing gray water compared to other environmental externalities based on the world input output database a structural decomposition analysis sda of gray water generation shows that domestic demand for food is the main driver of gray water changes in all countries while relocation of industrial activities to developing nations has disproportionally transferred this burden from developed countries manufacturing industries we highlight that while national policies should target water pollution from the agri food sector within each country water discharges from manufacturing sectors in global value chains need to be regulated from an international perspective besides the empirical evidence on water pollution drivers currently lacking in the environmental literature this paper also introduces a novel hybrid multiplicative additive sda that overcomes the issue of distributing large interaction terms in standard additive models and allows simulating mitigation scenarios it portrays the heterogeneity among sectors of how environmental abatement policies affect water and air pollution

drivers of provincial so2 emissions in china based on multi regional input output analysis abstract studying the driving factors of pollutant emissions is of great significance for china in the formulation of pollution control strategies existing studies mainly focus on the causes of national aggregate emission changes however considering the large differences among provinces in china and their close economic linkages it is necessary to develop a provincial level analysis to shape provincial policies for emission reduction using the multi regional input output mrio tables of 30 provinces in china and adopting structural decomposition analysis we analyze how changes in the end of pipe treatment cleaner production economic production structure domestic final use domestic exports and international exports drive national and provincial so2 emissions decomposition results show that during 2002 2010 the absolute value of each effect based on the mrio model is higher than that based on the national aggregate input output model which indicates that the existing studies adopting the national average data conceal the variation in the driving factors and underestimate their contributions to so2 emission changes the decomposition results based on mrio model further show that the end of pipe treatment and cleaner production are the major emission reduction factors for all provinces and the effect of the former has noticeably increased during 2007 2010 for the eastern provinces interestingly the economic production structure becomes a major emission reduction factor during the period of 2007 2010 changes in domestic final demand domestic exports and international exports exhibit significantly different contributions among provinces the increased final demand in eastern provinces largely drive so2 emissions for all provinces based on the above findings policy implications that address the so2 emission reduction issues are proposed

the role of co2 embodiment in us china trade abstract this study examines the influence of us china trade on national and global emissions of carbon dioxide co2 the three basic questions are as follows 1 what amount of co2 emissions is avoided in the us by importing chinese goods 2 how much are co2 emissions in china increased as a result of the production of goods for export to the us and 3 what are the impacts of us china trade on global co2 emissions our initial findings reveal that during 1997 2003 1 us co2 emissions would have increased from 3 to 6 if the goods imported from china had been produced in the us 2 about 7 14 of china s current co2 emissions were a result of producing exports for us consumers and 3 us china trade has increased global co2 emissions by an estimated 720 million metric tons we suggest that the export of us technologies and expertise related to clean production and energy efficiency to china could be a win win strategy for both countries for reducing their trade imbalance and mitigating global co2 emissions improved international accounting methodologies for assigning responsibility for co2 emissions must be designed to account for the dynamic nature of international trade

carbon dioxide emission drivers for a typical metropolis using input output structural decomposition analysis as the capital of china beijing is regarded as a major metropolis in the world study of the variation in temporal co2 emissions generated by the driving forces in beijing can provide guidance for policy decisions on co2 emissions mitigation in global metropolises based on input output structural decomposition analysis io sda we analysed the driving forces for the increment in co2 emissions in beijing from both production and final demand perspectives during 1997 2010 according to our results the co2 emission growth in beijing is driven mainly by production structure change and population growth partly offset by co2 emission intensity reduction as well as the decline in per capita final demand volume during the study period final demand structure change has a limited effect on the change in the co2 emissions in beijing from the final demand perspective urban trades urban residential consumption government consumption and fixed capital formation are mainly responsible for the booming emissions this study showed how the top down io sda methodology was implemented on a city scale policy implications from this study would be helpful for addressing co2 emissions mitigation in global capital cities and metropolises

the effect of globalisation on water consumption a case study of the spanish virtual water trade 1849 1935 abstract this paper aims to analyse the impact on water consumption of trade expansion in the first era of globalisation to that end we have chosen the case of spain a semi arid country with significant cyclical water shortages more specifically we are interested in answering the following questions what volume of water was required for exports of agricultural and food products how did this variable evolve over time which factors drove this evolution in short we wish to understand the impact on water resources of spain s entry into world agriculture and food markets firstly we examine virtual water trade flows in the long run secondly we attempt to disentangle certain major driving forces underlying these trajectories in order to establish the role played by trade in the final net balance of water a decomposition analysis da is applied our findings show the great pressures that the first globalisation imposed on not only domestic but also foreign water resources trade volumes as well as trade patterns were essential factors driving rising virtual water flows while yield improvements contributed smoothly to moderation in the expansion of water flows

nobel lecture the economic way of looking at behavior an important step in extending the traditional theory of individual rational choice to analyze social issues beyond those usually considered by economists is to incorporate into the theory a much richer class of attitudes preferences and calculations while this approach to behavior builds on an expanded theory of individual choice it is not mainly concerned with individuals it uses theory at the micro level as a powerful tool to derive implications at the group or macro level the lecture describes the approach and illustrates it with examples drawn from my past and current work
