the impact of climate targets on future steel production an analysis based on a global energy system model this paper addresses how a global climate target may influence iron and steel production technology deployment and scrap use a global energy system model etsap tiam was used and a scrap availability assessment model saam was developed to analyse the relation between steel demand recycling and the availability of scrap and their implications for steel production technology choices steel production using recycled materials has a continuous growth and is likely to be a major route for steel production in the long run however as the global average of in use steel stock increases up to the current average stock of the industrialised economies global steel demand keeps growing and stagnates only after 2050 due to high steel demand levels and scarcity of scrap more than 50 of the steel production in 2050 will still have to come from virgin materials hydrogen based steel production could become a major technology option for production from virgin materials particularly in a scenario where carbon capture and storage ccs is not available imposing a binding climate target will shift the crude steel price to approximately 500 usd per tonne in the year 2050 provided that ccs is available however the increased prices are induced by co2 prices rather than inflated production costs it is concluded that a global climate target is not likely to influence the use of scrap whereas it shall have an impact on the price of scrap finally the results indicate that energy efficiency improvements of current processes will only be sufficient to meet the climate target in combination with ccs new innovative techniques with lower climate impact will be vital for mitigating climate change

factors that influence carbon emissions due to energy consumption based on different stages and sectors in china abstract this study analyzes carbon emissions due to energy consumption based on different stages and sectors in china and by applying the logarithmic mean divisia index decomposition method carbon emissions were decomposed into energy structure energy intensity economic structure and economic output effects the study period was divided into high efficiency and high output low efficiency and low output high efficiency and low output and low efficiency and high output considering different carbon emission characteristics and economic development carbon emissions exhibit different characteristics at different stages the degree of increase in carbon emissions at these stages depends on the combined effect of the energy efficiency and the economic output the main factor driving carbon emissions was the economic output effect in each stage and the main factor inhibiting carbon emissions was the energy intensity effect the economic and energy structures had only a modest effect on carbon emissions at each stage the industry sector was the top contributor to carbon emissions followed by the transport sector the policy implications in terms of economic growth the economic structure and energy consumption are discussed in relation to the different stages

decoupling china s carbon emissions increase from economic growth an economic analysis and policy implications as the world s second largest carbon emitter china has long been criticized as a free rider benefiting from other countries efforts to reduce greenhouse gas emissions but not taking responsibility for its own emissions china has been singled out as one of the major targets at the subsequent negotiations after the kyoto meeting bq analyzing the historical contributions of interfuel switching energy conservation economic growth and population expansion to china s co2 emissions during 1980 97 this article clearly demonstrates that the above criticism is unjustified moreover given the fact that the role of china is an issue of perennial concern at the international climate change negotiations the article envisions some efforts and commitments that could be expected from china until its per capita income catches lip with the level of middle developed countries by emphasizing the it win win strategies these efforts and commitments are unlikely to jeopardize china s economic development and at the same time would give the country more leverage at the international climate change negotiations subsequent to the buenos sires meeting c 2000 elsevier science ltd all rights reserved

evolution of the brazilian residential carbon footprint based on direct energy consumption as one of the leading nations on climate negotiations brazil has to go beyond its voluntary commitment to reduce its carbon footprint and become a more constructive and less low key player in the

interest rate pass through and monetary transmission evidence from individual financial institutions retail rates official interest rate changes should influence short rates on money market instruments and retail products such as deposit accounts and mortgages but complete pass through is often taken for granted this paper provides a theoretical and econometric framework for assessing the evidence for this assumption using seventeen years of monthly data for rates on thirteen deposit and mortgage products offered by individual uk financial institutions the methodology allows for asymmetries and non linearities in adjustment and the results show that the speed of adjustment in retail rates depends on whether the perceived gap between retail and base rates is widening or narrowing

economic vs non material incentives for participation in an in kind payments for ecosystem services program in bolivia abstract this study examines the motivations that drive participation in a compensation program for environmental conservation in bolivia previous research on payments programs suggests that institutions that appeal to both economic and non material incentives should be encouraged this program attempts such a strategy offering in kind compensation for conservation while simultaneously attempting to engage with environmental values and traditional social norms i take advantage of a comprehensive household survey conducted prior to the offer of the program and employ means comparison tests and multi level regression analysis to compare those who chose to participate with those who did not my research examines whether motivations for participating in this program reflected purely financial calculations regarding the costs and benefits of the program or whether non financial motivations such as environmental or social beliefs and norms played a role as well i find evidence that the program s effort to engage with social motivations was successful and that social factors not financial incentives alone affect participation in the program findings also suggest that environmental values did not play a very large role and that the financial determinants of participation are related mainly to prohibitive costs or barriers to entry rather than the size of anticipated benefits

development of method for estimation of world industrial energy consumption and its application abstract the energy balances published by the international energy agency iea are one of the most valuable sources of energy statistics covering world energy supply and demand however some issues arise when these data are analyzed or used directly even when industrial energy consumption alone is examined at least three types of issues are encountered missing data large amounts of misallocated data in some countries and numerous unrealistic outliers in the time series variations when we deal with only a few regions we can look at data one by one and modify them in this case we are going to overcome these issues with a systematic method because the data covers world including more than a hundred regions this paper proposes a data reconciliation method to treat these issues and describes its application to world industrial energy consumption as a result of its application we found that the three issues mentioned above seemed to be overcome the degree of the reconciliation by region showed that oecd countries degree tends to be smaller than those of non oecd countries however not all of the oecd countries have low values and some countries such as the united states have high values

what is the major determinant of cross border banking flows abstract this study examines the major determinant of cross border credit flows through global banks across 70 countries employing a bayesian dynamic latent factor model we decompose volatilities of banking flows into the contribution of a global common factor regional common factor and country specific factor the results indicate that the global and regional common factor explains about 40 50 percent of volatility in overall cross border banking flows in particular the contribution of the global common factor increased in the 2000s simultaneously main determinants are largely heterogeneous across countries this implies that the desirable policy response to credit inflows may differ for each host country

who trades water allocations evidence of the characteristics of early adopters in the goulburn murray irrigation district australia 1998 1999 this article applies a model of innovation to analyze the characteristics of irrigators within the goulburn murray irrigation district in australia and examines the efficiency of the early water market in the late 1990s using multinominal and binary logit analyses we identify the factors associated with irrigators who sold or bought water allocations during 1998 1999 and irrigators who at that time had never participated in any kind of water trading contrary to expectations we find that early adopters of water trading were older farmers with low farm productivity but that in line with theory they had higher levels of education had spent less time farming had larger irrigated area farm operating surplus and farm assets owned farms that were more intensively farmed and were more progressive in their planning there was only weak evidence to suggest that water moved from lower value uses to higher value uses suggesting the water allocation market had limited efficiency in its initial years

decoupling economic growth from carbon dioxide emissions in china a sectoral factor decomposition analysis china is facing the dilemma of how to coordinate economic development and carbon dioxide co2 emissions reduction this paper investigates the decoupling effect of economic growth from co2 emissions in china during the period 1992 2012 using the logarithmic mean divisia index lmdi method we decompose the driving forces of the decoupling of economic growth from co2 emissions in china s five major economic sectors into several factors and measure the contribution of each factor to the decoupling of china s overall economy from co2 emissions the results show that china performed the weak decoupling of economic growth from co2 emissions during 1992 2012 and so did all its five major sectors such a state did not occur smoothly and presented five different stages energy intensity and economic activity level were the most important factors affecting the decoupling in china energy intensity decreased in all sectors indicating a large acceleration for the sectoral decoupling states this finding is applicable to process carbon intensity in industrial sector and energy emission factor in agricultural industrial construction and service sectors in terms of sectoral effects on the decoupling in china industrial sector played a dominant role while construction sector had the most marginal influence the economic activity level and economic share of industrial sector exerted the most negative effects on the decoupling the energy intensity of industrial sector played a key role in promoting the national decoupling state while the energy emission factor of agricultural sector contributed the least

taming the global financial cycle what role for the global financial safety net abstract an ongoing active debate considers the role of the global financial cycle gfc in driving international capital flows especially in emerging economies as well as the policy options available to absorb their impact we make two contributions to the debate first we rely on a structural measure of the gfc developed in a companion paper to identify episodes of large capital flows and currency crises driven by global conditions second using both ols and instrumental variables we evaluate whether the availability and actual use of elements of the global financial safety net gfsn can help emerging markets cushion the impact of these episodes we find some evidence that potential access to imf support can help countries we also find that the use of imf support and reserves cushions the impact of global shocks on gdp growth this effect is quite heterogeneous across types of crises and across time as it is mostly present during currency crises and the benefits only occur with a delay

index decomposition analysis applied to co2 emission studies index decomposition analysis ida was first extended from energy consumption to energy related co2 emission studies in 1991 since then many studies have been reported covering various countries and emission sectors however unlike the case of energy consumption studies a comprehensive literature survey that focuses specifically on emission studies has so far not been reported in this paper we attempt to fill this gap by reviewing 80 papers appearing in peer reviewed journals from 1991 to 2012 in this application area the first part of this paper deals with the developments with regard to the ida approaches used by researchers and the scope and focus of their studies in the second part the empirical results reported in the surveyed studies are analyzed consolidated and presented by emission sector the objective is to reveal the relative contributions of key effects on changes in the aggregate carbon intensity and this is done by emission sector and by country the findings of both parts are useful in understanding the development of ida in the application area of emission study as well as the key drivers of aggregate carbon intensities in the past and their possible future developments

club convergence in carbon dioxide emissions we examine convergence in carbon dioxide emissions among 128 countries for the period 1960 2003 by means of a new methodology introduced by phillips and sul econometrica 75 6 1771 1855 2007a contrary to previous studies our approach allows us to examine for evidence of club convergence i e identify groups of countries that converge to different equilibria our results suggest convergence in per capita co2 emissions among all the countries under scrutiny in the early years of our sample however there seem to be two separate convergence clubs in the recent era that converge to different steady states interestingly we also find evidence of transitioning between the two convergence clubs suggesting either a slow convergence between the two clubs or a tendency for some countries to move from one convergence club to the other

underlying causal factors of the european union energy intensity econometric evidence abstract the aim of the research is to determine the main factors that define the level of energy intensity in the countries of the european union the research was conducted by estimation of six baseline and six auxiliary regressions with and without time lags in form of one way fixed and random effects error component models on different unbalanced panel data samples covering the period 1995 2015 the obtained baseline regressions results generate three sets of findings the first set consists of extremely robust findings relating to the positive influence of gross fixed capital formation and industrial gross value added and negative effects of real per capita gross domestic product and oil products retail price these variables are statistically significant in all 36 baseline empirical models the second set of results consists of quite robust findings relating to insignificant influence of foreign direct investment and negative influence of coal price according to the results it cannot be confirm the hypothesis of energy saving technology transfer via foreign direct investments in european union member states the third set of results shows that the research has failed to generate any robust findings for economic openness import ratio urbanization and natural gas price which means that the effect of these determinants on energy intensity in european union member states is unspecified finally auxiliary regressions estimation results show that changes in the sectorial composition within the european union member states economies have not enhanced energy saving technological transfer via foreign direct investments

understanding global liquidity abstract we explore the concept of global liquidity based on a factor model estimated using a large set of financial and macroeconomic variables from 24 advanced and emerging market economies we measure global liquidity conditions based on the common global factors in the dynamics of liquidity indicators by imposing theoretically motivated sign restrictions on factor loadings we achieve a structural identification of the factors the results suggest that global liquidity conditions are largely driven by three common factors and can therefore not be summarised by a single indicator these three factors can be identified as global monetary policy global credit supply and global credit demand

energy from sugarcane bagasse under electricity rationing in brazil a computable general equilibrium model in the midst of the institutional reforms of the brazilian electric sectors initiated in the 1990s a serious electricity shortage crisis developed in 2001 as an alternative to blackout the government instituted an emergency plan aimed at reducing electricity consumption from june 2001 to february 2002 brazilians were compelled to curtail electricity use by 20 since the late 1990s but especially after the electricity crisis energy policy in brazil has been directed towards increasing thermoelectricity supply and promoting further gains in energy conservation two main issues are addressed here firstly we estimate the economic impacts of constraining the supply of electric energy in brazil secondly we investigate the possible penetration of electricity generated from sugarcane bagasse a computable general equilibrium cge model is used the traditional sector of electricity and the remainder of the economy are characterized by a stylized top down representation as nested ces constant elasticity of substitution production functions the electricity production from sugarcane bagasse is described through a bottom up activity analysis with a detailed representation of the required inputs based on engineering studies the model constructed is used to study the effects of the electricity shortage in the preexisting sector through prices production and income changes it is shown that installing capacity to generate electricity surpluses by the sugarcane agroindustrial system could ease the economic impacts of an electric energy shortage crisis on the gross domestic product gdp

decomposition analysis of the variations in residential electricity consumption in brazil for the 1980 2007 period measuring the activity intensity and structure effects abstract introduced at the end of the 1970s to study the impacts of structural changes on electricity consumption by industry index decomposition analysis techniques have been extended to various other areas to help in the formulation of energy policies notably in developed countries however few authors have applied these techniques to study the evolution of energy consumption in developing countries in brazil the few available studies have focused only on the industrial sector in this article we apply the decomposition technique called the logarithmic mean divisia index lmdi to electricity consumption of the brazilian residential sector to explain its evolution in terms of the activity structure and intensity affects over the period from 1980 to 2007 the technique is sufficiently robust and flexible to perform this analysis by disaggregating residential consumers by consumption classes and regions of the country among the main results is measurement of the impact of government programs for income transfer and universal service on variations in residential consumption typical of developing countries

long term changes in co2 emissions in austria and czechoslovakia identifying the drivers of environmental pressures this study presents fossil fuel related co2 emissions in austria and czechoslovakia current czech republic and slovakia for 1830 2000 the drivers of co2 emissions are discussed by investigating the variables of the standard kaya identity for 1920 2000 and conducting a comparative index decomposition analysis proxy data on industrial production and household consumption are analysed to understand the role of the economic structure co2 emissions increased in both countries in the long run czechoslovakia was a stronger emitter of co2 throughout the time period but per capita emissions significantly differed only after world war i when czechoslovakia and austria became independent the difference in co2 emissions increased until the mid 1980s the period of communism in czechoslovakia explained by the energy intensity and the composition effects and higher industrial production in czechoslovakia counterbalancing factors were the income effect and household consumption after the velvet revolution in 1990 czechoslovak co2 emissions decreased and the energy composition effect and industrial production lost importance despite their different political and economic development austria and czechoslovakia reached similar levels of per capita co2 emissions in the late 20th century neither austrian eco efficiency nor czechoslovak restructuring have been effective in reducing co2 emissions to a sustainable level

transaction costs in pollution markets an empirical study this paper studies a market in pol lution permits launched in los angeles in 1994 this tradable permit market has been projected to lead to substantial cost savings due to the flex ibility it provides firms in terms of compliance with environmental regulation this paper shows that transaction costs can play an important role in the initial years of the program the transac tion cost variables have been defined to include search costs and information costs these costs are significant in explaining non participation of some firms in the market the study also draws policy implications for the development of future emissions trading programs jel q28 q25

impacts of shifting china s final energy consumption to electricity on co2 emission reduction abstract electrification is advocated by both academics and the chinese government to control air pollution and promote productivity however the problem remains to be solved of how to achieve the trade off between reducing co 2 emissions and maintaining economic growth when switching from various fuels to electricity under the policy support in view of this after analyzing the effects of exogenous shocks in various fuel demands based on impulse response functions of several vector autoregression models this paper measures the current and long term impacts of electrification on gdp and co 2 emissions finally some typical cases of replacement of fossil fueled appliances by electrical counterparts encouraged by the government are assessed the main findings are 1 almost all of the exogenous shocks in fuel demands have positive effects on both gdp and co 2 emissions while the gas shock has a slightly negative effect on gdp 2 carbon intensity decreases and even co 2 emission reductions with increased gdp are potentially achieved in both current and permanent periods for coal electricity and oil electricity switching while gas electricity switching is not a wise choice in view of co 2 emission reduction in the long run 3 the alternative electric appliances for electrification have very different impacts on co 2 emission reduction

bank integration and co movements across housing markets this paper investigates whether bank integration measured by cross border bank flows can capture the co movements across housing markets in developed countries by using a spatial dynamic panel model the transmission can occur through a global banking channel in which global banks intermediate wholesale funding to local banks changes in financial conditions are passed across borders through the banks balance sheet exposure to credit currency maturity and funding risks resulting in house price spillovers while controlling for country level and global factors we find significant co movement across housing markets of countries with proportionally high bank integration bank integration can better capture house price co movements than other measures of economic integration once we account for bank exposure other spatial linkages traditionally used to account for return co movements across region such as trade foreign direct investment portfolio investment geographic proximity etc become insignificant moreover we find that the co movement across housing markets decreases for countries with less developed mortgage markets characterized by fixed mortgage rate contracts low limits of loan to value ratios and no mortgage equity withdrawal

where are the industrial technologies in energy economy models an innovative cge approach for steel production in germany top down computable general equilibrium cge models are used extensively for analysis of energy and climate policies energy intensive industries are usually represented in top down economic models as abstract economic production functions commonly of the constant elasticity of substitution ces or translog functional form this study explores methods for improving the realism of energy intensive industries in top down economic models we replace a ces production function with a set of specific technologies and provide a comparison between the traditional production function approach in cge models and an approach with separate technologies for making iron and steel in particular we investigate the response of the iron and steel sector to a set of co2 price scenarios our technology based integrated approach permits a choice between several technologies for producing iron and steel and allows for shifts in technology characteristics over time towards best practice innovative technologies in addition the general equilibrium framework allows us to analyze interactions between production sectors for example between electricity generation and iron and steel production investigate simultaneous economy wide reactions and capture the main driving forces of greenhouse gas emissions reductions under a climate policy we conclude that technology specific effects are crucial for the economic assessment of climate policies in particular the effects relating to process shifts and fuel input structure

decomposition analysis of gas consumption in the residential sector in ireland abstract to date decomposition analysis has been widely used at the macro economic level and for in depth analyses of the industry and transport sectors however its application in the residential sector has been rare this paper uses the log mean divisia index i lmdi i methodology to decompose gas consumption trends in the gas connected residential sector in ireland from 1990 to 2008 which despite an increasing number of energy efficiency policies experienced total final consumption growth of 470 the analysis decomposes this change in gas consumption into a number of effects examining the impact over time of market factors such as a growing customer base varying mix of dwelling types changing share of vacant dwellings changing size of new dwellings the impact of building regulations policy and other factors such as the weather the analysis finds the most significant effects are changing customer numbers and changing intensity the analysis also quantifies the impact of building regulations and compares it with other effects such as changing size of new dwellings by comparing the historical impact on gas consumption of policy factors and non policy factors this paper highlights the challenge for policy makers in achieving overall energy consumption reduction

change in energy related co2 carbon dioxide emissions in portuguese tourism a decomposition analysis from 2000 to 2008 abstract tourism is an activity with great potential in portugal at a time of economic crisis tourism is seen as an opportunity to boost the economy and provide sustainable economic growth this strategic path based on tourism has to be accomplished in order to make better use of the economic advantages but at the same time respecting the environment and environmental goals to which portugal is committed so it becomes important to analyze what effects contribute more to emissions in this sector as well as which tourism subsectors are more responsible for the increase of emissions the objective of this work is to identify the effects in which co2 carbon dioxide emissions in tourism can be broken down and analyzed as well as their evolution and which of them has more importance in determining emissions for that in this study a decomposition technique based on logarithmic mean divisia index was used in the 2000 2008 period for five tourism subsectors in portugal in general tourism activity is the most important effect energy mix carbon intensity and energy intensity effects also proved important

impacts of urbanization on renewable energy consumption in china abstract in this paper we used the logarithmic mean divisia index method to investigate the impact of urbanization on renewable energy consumption growth recg the growth in renewable energy consumption is attributed to the urbanization effect energy mix effect energy intensity effect economic effect and population effect recg can be roughly divided into the slow growth stage the fluctuant growth stage and the accelerated growth stage the results showed that the energy mix effect economic effect and population effect positively affected recg however a significantly negative relationship was found between energy intensity and recg furthermore the contribution of urbanization differed in recg stages and urbanization contributed more to the total energy consumption growth than to recg this study would thus provide policymakers with insights about the link between urbanization and renewable energy consumption

decomposition of aggregate carbon intensity for the manufacturing sector comparison of declining trends from 10 oecd countries for the period 1971 1991 abstract as with total energy consumption or aggregate energy intensity changes in aggregate carbon intensity may also be decomposed or attributed to changes in various components including fuel mix for electricity generation final energy mix sub sectoral economic activity and sub sectoral energy intensities the adaptive weighted divisia rolling base year index specification is applied to total carbon emissions from the manufacturing sector of 10 oecd countries for the period 1971 1991 declines in aggregate carbon intensity for these countries range from 70 and may be primarily attributed to decreases in energy intensity i e increases in the average factor productivity of energy however these declines in aggregate carbon intensity appear to have a complex linkage to increases in energy prices as well as changes in other determinants of gross industrial output

decomposition of co2 emissions change from energy consumption in brazil challenges and policy implications this study evaluates the changes in co2 emissions from energy consumption in brazil for the period 1970 2009 emissions are decomposed into production and consumption activities allowing computing the full set of energy sources consumed in the country this study aims to develop a comprehensive and updated picture of the underlying determinants of emissions change from energy consumption in brazil along the last four decades including for the first time the recently released data for 2009 results demonstrate that economic activity and demographic pressure are the leading forces explaining emission increase on the other hand carbon intensity reductions and diversification of energy mix towards cleaner sources are the main factors contributing to emission mitigation which are also the driving factors responsible for the observed decoupling between co2 emissions and economic growth after 2004 the cyclical patterns of energy intensity and economy structure are associated to both increments and mitigation on total emission change depending on the interval the evidences demonstrate that brazilian efforts to reduce emissions are concentrated on energy mix diversification and carbon intensity control while technology intensive alternatives like energy intensity has not demonstrated relevant progress residential sector displays a marginal weight in the total emission change

mitigating climate change decomposing the relative roles of energy conservation technological change and structural shift abstract we decompose the contribution of five drivers of energy use and co 2 emissions reductions in achieving climate change goals over 2005 2100 for various climate policy scenarios this study contributes to the decomposition literature in three ways first it disaggregates drivers of energy demand into technological progress and demand for energy services represented in terms of useful energy allowing us to estimate their contributions independently an improvement over other economy wide decomposition studies secondly this approach reduces the ambiguity present in many previous measures of structural change we delineate structural shifts into two separate measures changes in fuel mix within a given resource or service pathway and changes in mix among distinct energy resources or end use services finally this study applies decomposition methods to energy and emission trajectories from two mutually informing perspectives i primary energy resources crude oil natural gas coal nuclear and renewables and ii end uses of energy services residential and commercial buildings industry and transportation our results show that technological improvements and energy conservation are important in meeting climate goals in the first half of the coming century and that nuclear and renewable energy and ccs technology are crucial in meeting more stringent goals in the second half of the century we examine the relative roles of the drivers in reducing co 2 emissions separately for developed and developing regions although the majority of energy and emission growth and by extension the greatest opportunities for mitigation will occur in developing countries the decomposition shows that the relative roles of the five drivers are broadly consistent between these two regions

on the sources of business cycles in the g 7 abstract this paper examines sources of cyclical movements in output inflation and the term structure of interest rates in the g 7 it employs a novel identification approach which uses the sign of the theoretical cross correlation function in response to shocks to catalog orthogonal disturbances we find that demand shocks are the dominant source of output and inflation fluctuations in several of the g 7 countries the proportion of term structure variability explained by different structural sources does not depend on the horizon apart from the us and canada structural shocks are nearly uncorrelated across countries

the lmdi approach to decomposition analysis a practical guide in a recent study ang energy policy 32 2004 compared various index decomposition analysis methods and concluded that the logarithmic mean divisia index method is the preferred method since the literature on the method tends to be either too technical or specific for most potential users this paper provides a practical guide that includes the general formulation process summary tables for easy reference and examples

energy intensity trend explained for sao paulo state abstract a sectorial analysis and a logarithmic mean divisia index lmdi technique are used in this paper to decompose the energy intensity of the state of sao paulo from 1995 to 2012 into the economic activity effect and the energy efficiency effect this study contributes the following observations 1 the world energy intensity has decreased steadily but the energy intensity of the sao paulo state has been volatile and has declined 2 3 since 1995 2 in the period of study declining energy intensity of the primary and tertiary sectors was observed in contrast the energy intensity of the secondary sector has been gradually increasing 3 the energy efficiency effect was the primary driver of energy intensity change through 2007 and the economic activity effect subsequently had an increasingly more important role in the change 4 the economic structure remained constant until 2004 when the services sector shift became more significant it is hypothesized that the increasing energy intensity from 2005 to 2009 was caused by the growth of inefficient sugarcane bagasse consumption

the future natural gas consumption in china based on the lmdi stirpat plsr framework and scenario analysis abstract due to the growing pollution concerns in china there have been major efforts to design interrelated environmental protection policies as the policy of reducing coal consumption is implemented china s natural gas consumption is expected to commensurately rise such a trend may lead to the significant impacts on china s energy security and the global gas market this paper empirically investigates the relationship between the natural gas consumption and influencing factors in a comprehensive lmdi stirpat plsr framework it is found that fossil energy structure and non clean energy structure are the most important factors followed by urbanization per capita gdp industrialization and industrial energy intensity and then these factors from lmdi decomposition are innovatively divided into economic development and cleaning indicators when using scenario analysis to forecast china s natural gas consumption the prediction results suggest that economic development with high clean energy system would make a significant increase in gas consumption a commensurate increase in demand even the system of economic energy under scenario of low economic development and low clean as china would depend on gas imports to meet this demand there may be a serious supply shortage by 2020 therefore the government should consider the future energy security issue in making economic and environmental policies

effects of urbanisation on energy consumption in china as a key issue in china s economic development urbanisation creates increasing pressure on energy supply and the natural environment thus a better understanding of the relationship between urbanisation and energy consumption is necessary for chinese decision makers at various levels to address energy security and sustainable economic and social development this paper empirically investigates the effects of china s urbanisation on residential energy consumption rec and production energy consumption pec through a time series analysis the results show that compared with rural areas urbanisation slows per capita rec growth because of the economy of scale and technological advantages associated with urbanisation but has greater promotional effects on the growth of rec and the improvement of rec structure the economic growth caused by urbanisation most significantly contributes to an increase in pec whereas technological advancement was found to reduce the scale of pec except from 2001 to 2005 finally the structural effect of the energy supply increased rather than decreased china s pec and the effect of industrial structure adjustment on pec was found to be insignificant

what drives intersectoral co2 emissions in china abstract aiming to identify the intersectoral linkage of larger co2 emissions sectors this paper studies the co2 emissions elasticity of technical and final demand coefficients using the input output technique the results show that the greatest emission coefficient elasticities are those related to transactions between construction and manufacture of non metallic mineral products between gross fixed capital formation and construction and between agriculture and processing and manufacture of food and production and supply of electric power and heat power and mining and washing of coal all these transactions between these sectors imply that co2 emissions control policy only for a specific sector maybe have no obvious co2 emissions mitigations if national government promote the growth of those sectors which have the biggest emission coefficient sensitivity with it now chinese government formulates the policy to promote new type urbanization urbanization will cause the gross fixed capital formation in construction and the more demands for the products of manufacture of non metallic mineral products production smelting and pressing of ferrous metals and supply of electric power and heat power so how to balance the carbon emissions in larger emissions sectors and rapid urbanization is a big challenge for decision makers

the impact of china s differential electricity pricing policy on power sector co2 emissions abstract this article investigates the impact of china s differential electricity pricing policy on power sector co 2 emissions using the logarithmic mean divisia index method the differential pricing policy intended to reduce energy intensity in manufacturing is being implemented in eight electricity intensive industries the study finds that during 2004 2009 the policy accounted for a drop of roughly 115 twh in electricity use which amounted to a reduction of 82 million tons of co 2 emissions the policy has been most effective in reducing electricity use in the nonferrous metal smelting and rolling industry and least effective in the ferrous metal smelting and rolling industry because the differential pricing policy has had significantly different effects across industries improving the policy s design and implementation going forward will require a more detailed understanding and analysis of how it can be better tailored to individual industries

international business cycles the authors estimate a dynamic two country model in which economic fluctuations are driven by a worldwide supply shock country specific supply shocks and relative fiscal money and preference shocks identification is achieved using only long run restrictions based on a theoretical model the main results are 1 supply shocks particularly country specific ones are very important in generating international business cycles and 2 although the post 1973 flexible exchange rate period has been inherently more volatile there are no differences in transmission properties of economic disturbances across exchange rate regimes for the endogenous variables they focus on copyright 1993 by american economic association

international business cycles world region and country specific factors the paper investigates the common dynamic properties of business cycle fluctuations across countries regions and the world we employ a bayesian dynamic latent factor model to estimate common components in macroeconomic aggregates output consumption and investment in a 60 country sample covering seven regions of the world the results indicate that a common world factor is an important source of volatility for aggregates in most countries providing evidence for a world business cycle we find that region specific factors play only a minor role in explaining fluctuations in economic activity we also document similarities and differences across regions countries and aggregates jel f41 e32 c11 c32

the triptych approach revisited a staged sectoral approach for climate mitigation abstract the triptych approach is a method for allocating future greenhouse gas ghg emission reductions among countries under a post 2012 international climate mitigation regime based on technological criteria at the sector level and accounting for structural differences the emission allowances are decomposed according to sectors thereby enabling the link to real world emission reduction strategies to be more concrete the new triptych approach presented here is a refinement of an earlier version in terms of an increased transparency and allowing a delayed participation for developing countries initial participation of developing countries with incentives but no penalties through no lose targets or sustainable development policies and measures for this article we calculated the emission reductions for countries for two technology oriented scenarios which stabilize ghg concentrations at 450 and 550 ppm co 2 eq respectively the reductions are ambitious but nonetheless compatible with existing technical reduction potentials as growth is allowed but efficiency has to be improved

swedish co2 emissions 1993 2006 an application of decomposition analysis and some methodological insights this study undertakes a decomposition analysis to identify the drivers of carbon dioxide emissions change in the swedish business and industry sectors 1993 2006 on aggregate energy intensity decreased but this does not seem to have been very important for reducing emissions rather fuel substitution seems to have been more important which is in line with findings from the decomposition literature on sweden however at the sectoral level we find no clear pattern of the effect of fuel substitution and energy intensity on emissions we also draw some methodological conclusions decomposition analysis should be undertaken at the most disaggregate level possible assessing decomposition results by summing results over several time periods leads to biased results and decomposition analysis should not be based only on some initial and final years of a long time period furthermore we address the problem of double counting energy flows in decomposition analysis of aggregate effects when the energy sector is included and point out potential problems related to output measured in monetary terms

retrospective and prospective decomposition analysis of chinese manufacturing energy use and policy implications abstract aims the industrial sector dominates the china s total energy consumption accounting for about 70 of energy use in 2010 hence this study aims to investigate the development path of china s industrial sector which will greatly affect future energy demand and dynamics of not only china but the entire world scope this study analyzes energy use and the economic structure of the chinese manufacturing sector the retrospective 1995 2010 and prospective 2010 2020 decomposition analyses are conducted for manufacturing sectors in order to show how different factors production growth structural change and energy intensity change influenced industrial energy use trends in china over the last 15 years and how they will do so up to 2020 conclusions the forward looking prospective decomposition analyses are conducted for three different scenarios the scenario analysis indicates that if china wants to realize structural change in the manufacturing sector by shifting from energy intensive and polluting industries to less energy intensive industries the value added average annual growth rates aagrs to 2015 and 2020 should be more in line with those shown in scenario 3 the assumed value added aagrs for scenario 3 are relatively realistic and are informed by possible growth that is foreseen for each subsector

energy intensity developments in 40 major economies structural change or technology improvement this study analyzes energy intensity trends and drivers in 40 major economies using the wiod database a novel harmonized and consistent dataset of input output table time series accompanied by environmental satellite data we use logarithmic mean divisia index decomposition to 1 study trends in global energy intensity between 1995 and 2007 2 attribute efficiency changes to either changes in technology or changes in the structure of the economy and 3 highlight sectoral and regional differences we first show that heterogeneity within each sector across countries is high these general trends within the sectors are dominated by large economies first and foremost the united states in most cases heterogeneity is lower within each country across the different sectors regarding changes of energy intensity at the country level improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries notable exceptions are japan the united states australia taiwan mexico and brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction

retracted factors affecting commercial energy consumption in pakistan progress in energy the purpose of this study is to identify major macroeconomic factors that enhance energy consumption for pakistan through the cointegration error correction model and granger causality tests over a 32 year time period i e between 1980 and 2011 the study employed the bivariate cointegration technique to estimate the long run relationship between the variables an error correction model was used to determine the short run dynamics of the system while granger causality test was used to find the directions between these variables the study investigates the relation between four energy consumption variables i e oil petroleum consumption gas consumption electricity consumption and coal consumption and four macroeconomic factors which have further sub classifications i e balance of payment bop factors i e exports imports trade deficit worker s remittances and current account balance fuel factors i e carbon dioxide emissions natural resource depletion and net forest depletion agricultural crops yield per hectare i e wheat rice sugarcane maize and cotton and industrial production items i e beverages cigarettes motor tyres motor tubes cycle tyres and cycle tubes in order to manage robust data analysis the result confirms the long run relationship between total commercial energy consumption and macroeconomic factors in pakistan as oil petroleum consumption increases exports fuel factors agricultural crops yield per hectare and industrial items however the intensity of these factors are different in nature carbon dioxide emissions net forest depletion beverages motor tyres and motor tubes are more elastic with oil petroleum consumption however oil petroleum consumption decreases trade deficit and workers remittances in pakistan gas electricity and coal consumption increases agricultural crops yield per hectare and industrial production which shows that as agriculture and industry modernizes energy demand increases energizing the food production chain is an essential feature of agricultural development which is a prime factor in helping to achieve food security in pakistan the empirical results only moderately support the conventional view that energy consumption has significant long run casual effect on macroeconomic variables in pakistan the present study finds evident of unidirectional causality between the commercial energy consumption factors and macroeconomic factors in pakistan however there is some bidirectional causality exist which is running between electricity consumption ec and exports ec to imports ec to carbon emissions ec to natural resource depletion nrd and ec to wheat the results conclude that macroeconomic variables tend to positively respond to total primary energy consumption this indicates that increasing total commercial energy consumption may cause growth variables which show that pakistan is an input driven economy

impacts of growth and structural change on co2 emissions of developing countries abstract carbon dioxide emissions the most significant greenhouse gas are growing at more rapid rates in developing economies relative to advanced economies this paper estimates the effects of the growth of gdp changes in industrial structure fuel mixes and energy efficiency on the carbon dioxide emissions of nine developing countries using a decomposition model policy implications for reducing emissions in the light of the findings are discussed

using logarithmic mean divisia index to analyze changes in energy use and carbon dioxide emissions in mexico s iron and steel industry using international comparisons and log mean divisia index this paper analyzes energy and co2 emission trends of mexico s iron and steel industry during the period 1970 2006 examining co2 emissions related to energy use and production process the decomposition analysis is based on the structure efficiency analysis for international comparisons considering industrial structure and the best available technology results show that for the period 1970 2006 activity drove up primary energy use by 227 instead of the actual 133 while structure and efficiency effects drove it down by 5 and by 90 respectively the important improvement in mexican iron and steel primary energy efficiency reduced the gap between best international practice and actual primary energy consumption from 103 in 1970 to only 15 in 2006 co2 emissions from fuel consumption and production process increased by 134 and in addition to structure and efficiency fuel share effect also drove down emissions by 4 2 in the entire period

the modest environmental relief resulting from the transition to the service economy a service transition is supposed to lead to the decline of energy intensity energy gdp we argue that this interpretation is overly optimistic because the shift to a service economy is somewhat of an illusion in terms of real production several recent studies of structural effects on energy intensity have made the error of using sector shares in current prices combined with gdp in constant prices which is inconsistent and ignores the different behaviour of prices across sectors we use the more correct method of sector shares in constant prices and make an attempt to single out the effect from the real service transition by using two complementary methods shift share analyses in current and constant prices and logarithmic mean divisia index lmdi for 10 developed and 3 emerging economies a service transition is rather modest in real terms the major driver of the decline in energy intensity rests within the manufacturing sector meanwhile the transition to a service sector had a small downward impact on energy intensity in 7 of the developed countries and no impact in the others for emerging economies like brazil mexico and india it is the residential sector that drives energy intensity down because of the declining share of this sector as the formal economy grows and as a consequence of switching to more efficient fuels less

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

the use of physical indicators for industrial energy demand scenarios abstract scientific information on the size and nature of the threat of climate change is needed by politicians in order to weight their decisions computerised models are extremely useful tools to quantify the long term effects of current policies this paper describes a new modelling approach that allows formulation of industrial energy demand projections consistent with the assumptions for scenario drivers such as gdp and population in the model a level of industrial production is used as a key variable and we define it in physical units rather than in monetary units the aim of this research is to increase insights that come with long term energy demand scenarios this research clearly shows that physical indicators provide additional insights in scenario analysis the use of physical indicators instead of monetary indicators seems to affect the energy scenarios significantly the differences with monetary indicators are larger in developing regions than in oecd regions we conclude that an integrated energy and materials approach reveals developments that are hardly visible using a monetary approach moreover this research shows the potential and benefits of the use of physical indicators for scenario development

decomposing the decoupling of co2 emissions and economic growth in brazil abstract this paper examines the occurrence of a decoupling between the growth rates in economic activity and co 2 emissions from energy consumption in brazil from 2004 to 2009 this decoupling was highlighted when economic activity and co 2 emissions moved in opposite directions in 2009 more generally we observe several periods of relative decoupling in brazil but not to the extent witnessed in 2009 to identify the determinants of emissions change we develop a decomposition model based on a log mean divisia index lmdi framework the results indicate that the carbon intensity and energy mix are the main determinant of emissions reduction in brazil between 2004 and 2009 modifications in the economy structure are also associated to emission mitigation in the period such evidence demonstrates similarities with events of decoupling registered for the interval 1980 1994 in brazil finds from brazil differ from observations in other countries in which improvement in energy intensity has been the most common determinant of emissions reduction

factors shaping aggregate energy intensity trend for industry energy intensity versus product mix understanding the mechanisms of change of energy consumption in industry has attracted much attention since the 1973 world oil crisis a popular line of research has been to decompose changes in the aggregate energy intensity of industry to give the relative impacts arising from energy intensity change and product mix change using a decomposition technique many empirical studies covering a large number of countries have been reported the main objective of this paper is to put together the empirical results reported in these studies in a coherent framework and identify possible systematic features of particular interest are the basic trends in this line of research the relative importance of energy intensity change and product mix change possible variations over time and between country groups in the energy impacts of these changes and inconsistencies in findings among studies an overview of the decomposition technique including its strengths weaknesses and role in industrial energy consumption studies is also presented

extended divisia index decomposition of changes in energy intensity a case of korean manufacturing industry abstract this study aims to examine the energy efficiency of the manufacturing industry of korea by using the extended divisia index decomposition of choi and ang 2012 first we applied the sato vartia index decomposition to the energy intensity of the manufacturing industry in korea second we attributed the growth rate of aggregate energy intensity to 10 sub manufacturing industries through two channels real energy intensity and structural change the result of the decomposition illustrates that the aggregate energy intensity index decreased in the period 1981 2010 the index decomposition analysis demonstrates that real energy intensity decreased by 85 85 whereas structural change increased energy intensity by 69 37 over the same period of time the negative effect of structural change is partly a result of the increasing portion of energy intensive industry in manufacturing the result reflects that industrial structure in korea can be an important aspect for improving energy efficiency

driving forces for aggregate energy consumption a cross country approach abstract although a cornerstone for development past and current energy use has often posed a major challenge for policymakers with respect to planning and management within this context in this paper an updated multi sectorial cross country assessment of energy consumption trends was undertaken aiming at identifying the main drivers of changes in aggregate energy consumption these drivers have been interpreted in the light of the policy measures that have been implemented over the years by different countries to achieve a sustainable development of the energy sector the cross country assessment encompasses a set of developed united kingdom portugal and spain and emerging brazil china and india countries resorting to the logarithmic mean divisia index lmdi decomposition method changes in the aggregate energy consumption were decomposed into three main explanatory effects activity structure and intensity the major findings achieved reflect the relevance of intensity and activity effects in detriment of the structural effect the assessment of energy consumption trends using the lmdi decomposition method provides critical information regarding which is the dominant factor that should be focused in policy design

influential factors of carbon emissions intensity in oecd countries evidence from symbolic regression abstract carbon emissions intensity is used as a yardstick to evaluate the relative extent of carbon emissions of a country to reduce carbon emissions intensity it is crucial to find out the dominant factors that enhance it and take actions to manage them this study is an attempt to employ symbolic regression method to explore the most influential factors of carbon emissions intensity in 34 oecd member countries using data from 1995 to 2014 rooted in genetic programming symbolic regression method can explore the inherent functional structures amidst the variables and could discover the influential factors robotically the results confirm that the influential factors of carbon emissions intensity vary from country to country gdp is found as the most frequent and important factor of carbon emissions intensity in 17 countries each of industrialization and technological innovation is the prominent factor in every 4 countries and each of urbanization total population and foreign direct investment plays a pro active role in 3 individual nations based on the empirical results some policy implications are also conferred

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

bigger cakes with fewer ingredients a comparison of material use of the world economy the amount of materials used worldwide in production and consumption increased by 56 from 1995 to 2008 using an index decomposition analysis based on the logarithmic mean divisia index we investigate the drivers of material use both on a global and a country scale we exploit a panel dataset of 40 countries accounting for 75 of worldwide material extraction and 88 of gdp from 1995 to 2008 the results show that economic growth and structural change towards material intensive countries explain most of the growth in global material use slight gains in material efficiency and falling importance of material intensive sectors have decelerating effects the country level analysis reveals substantial heterogeneity some nations exhibit stable or falling material use while it increases notably in most countries improving material efficiency is able to dampen growth of material use in important industrializing nations like china or india

research on the energy saving effect of energy policies in china 1982 2006 this paper summarizes the main energy policies of china from 1980 and divides them into three groups of policies two methods with and without antitheses and linear regression are created to evaluate the energy saving effects of the energy policies and the energy saving effects of these three groups of energy policies of china are evaluated by the two methods respectively it is concluded that with and without antitheses is used to evaluate short term effects and linear regression is used to evaluate long term effects

barriers to massachusetts forest landowner participation in carbon markets u s forests including family owned forests are important carbon sinks and sources for carbon sequestration family forest owners constitute a significant portion of the overall forestland in the u s but little is known about their preferences for participating in carbon sequestration programs the goal of this research is to understand what motivates massachusetts family forest owners to participate in carbon markets the study estimates the probability these landowners would engage in carbon sequestration programs using data from a survey of 930 massachusetts family forest owners results from a random effects ordered probit indicate that under a carbon scenario similar to the current voluntary scheme very few of these landowners would be interested in participating supply analysis indicates these landowners are more influenced to participate by factors other than price regression analysis results suggest that survey respondents are concerned about early withdrawal penalties additionality requirements and contract length forest owner harvesting plans opinions about forest usage and beliefs about climate change all play a significant role in the decision to participate the study suggests that policy makers should consider the reasons behind these low participation rates because private forest owners could play a pivotal role in the carbon sequestration potential of forests

energy intensity in the iron and steel industry a comparison of physical and economic indicators abstract energy consumption of the iron and steel industry is examined in seven countries brazil china france germany japan poland and the united states for the period 1980 1991 using a decomposition analysis based on physical indicators for process type and product mix we decompose intra sectoral structural changes and efficiency improvements specific energy consumption decreased in all countries except poland efficiency improvement played a key role in brazil china germany and the us while structural changes were the main driver for energy savings in france and japan we also compare the use of various economic indicators to physical indicators and find that they do not track physical developments well in poland or the developing countries we studied in the industrialized countries value added based energy intensity indicators generally reflect the specific energy consumption better than other economic indicators although large differences occur in individual years we found a smaller correlation between other economic indicators gross output and value of shipments and specific energy consumption we conclude that use of physical energy intensity indicators improves comparability between countries provides greater information for policy makers regarding intra sectoral structural changes and provides detailed explanations for observed changes in energy intensity

loan supply shocks during the financial crisis evidence for the euro area this paper employs a panel vector autoregressive model for the member countries of the euro area to explore the role of banks during the slump of the real economy that followed the financial crisis in particular we seek to quantify the macroeconomic effects of adverse loan supply shocks which are identified using sign restrictions we find that loan supply shocks significantly contributed to the evolution of the loan volume and real gdp growth in all member countries during the financial crisis however concerning both the timing and the magnitude of the shocks our results also indicate that the euro area was characterized by a considerable degree of cross country heterogeneity

analysis and decomposition of energy consumption in the chilean industry abstract with rising energy costs and climate change concerns energy efficiency will be important in maintaining competitiveness and reducing the environmental impact of industrial activities in this paper we study the chilean industrial sector which is the largest consumer of energy within the country energy demand and co 2 emissions in chile have grown rapidly in recent years while energy supply is mostly imported and subject to disruption therefore it is important to understand energy consumption in this sector and determine which sub sectors have the greatest potential to reduce energy consumption we used the index decomposition analysis ida applying the logarithmic mean divisia index method i lmdi i to quantify the impact of diverse driving factors on energy consumption furthermore a panel data analysis was used to determine whether there are differences in energy intensity across firms with different characteristics our results show that energy intensity has risen over time although energy consumption remains stable this fact supports the idea that energy efficiency policies could play an important role for the industrial sector additionally energy consumption and energy intensity follow different patterns in each sub sector therefore we conclude that the application of differentiated sectoral policies is preferable over a single global policy

evaluation of socio economic factors on co2 emissions in iran factorial design and multivariable methods abstract nowadays global co2 emissions play a focal role in the human sustainable development and environmental concern this paper investigates the relationships among co2 emissions and the efficient factors including energy consumption oil product gross domestic product gdp non oil gdp foreign direct investment fdi gas consumption citizen rate cost of energy number of vehicles and mean incoming urban and rural in iran over the period of 1976 2016 a factorial design was applied to screening the significant factors and their relations on carbon emissions the results indicated that energy consumption and its cost citizen rate non oil gdp and fdi have significant effects on co2 emissions and there is a linear relationship among these factors and co2 emissions the relationships among significant factors were evaluated for the first time by the latent variable modeling method using partial least square pls model the latent variable model results showed that the lower energy consumption leads to lower co2 emissions with a coefficient of 0 87 the results also indicated that citizen rate positively and fdi negatively the share of 13 and 4 are the other most important factors in raising co2 emissions by a directional relationship the share of energy cost and non oil gdp in explaining co2 emissions is minimal it was found that the chance of successful determination of critical factors on co2 emissions increases with these mathematical models

assessing eco efficiency through the dea analysis and decoupling index in the latin america countries abstract this study was developed according to a two step approach in the first step we provide an investigation of the changes in eco efficiency under constant and variable return to scale while on a second step the evaluation of the decoupling elasticity will be given the impacts of energy economic and environmental determinants inputs on the performance indicators of eco efficiency were calculated as the inverse of the carbon intensity ratio of the gdp over the co2 emissions both from the world development indicators database the changes in eco efficiency and the decoupling elasticity between co2 emissions and economic growth changes data was used for 16 latin america countries according to five year periods from 1994 to 2013 for all the five time span considered it is worth noting that the degree of technical efficiency for the latin america countries is lower than the degree of technological efficiency thus indicating that a portion of the overall inefficiency is due to the fact that these countries are producing below the production frontier rather than to an inefficient use of technology on average the results have confirmed that the technological scale change in energy production is the dominant factor influencing the optimal production frontier in the sample of countries under analysis complementarily according to the mixed results from the decoupling analysis we may conclude that the increase decrease of the co2 per capita emissions was due to other economic and environmental factors rather than to a negative positive effect of the gdp growth rate

consistent multi level energy efficiency indicators and their policy implications in order to cope with the global warming issue most of the asia pacific economic cooperation apec economies have made energy conservation policy a top priority in terms of their energy policies the energy efficiency indicators included in the present paper focus on the micro foundation aspects there are basically two types of energy efficiency indicators namely the economic thermodynamic energy efficiency indicators that use real gdp as the denominator and the physical thermodynamic energy efficiency indicators that are based on the output volume index while the common definitions and consistent methodology used in the present paper fulfill the iea pyramid eei concept the new methodology in this paper compares the decomposition effects between upstream and downstream industries when aggregating efficiency changes these decomposition effects can thereby provide valuable explanations for the energy conservation policy needed by energy policy and government administrators

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

the synchronization of credit cycles abstract this paper proposes a simple econometric procedure to test for the synchronization of credit cycles using a century of data for 14 advanced economies we find that credit cycle synchronization dropped in the early 1920s from initially relatively high levels between the 1920s and the 1970s synchronization was overall low and concentrated within five predominantly regional clusters however synchronization has significantly increased in the post bretton woods era and has become less associated with geographic proximity australia denmark france italy japan norway spain switzerland the uk and the us form a single major credit cycle cluster since the 1970s a smaller cluster is formed by canada the netherlands and sweden while the german credit cycle follows a distinct path using logistic regressions we find that the synchronization of credit and business cycles go hand in hand our findings are especially relevant for the international coordination of macroprudential policy as well as to spur and inform further analysis on credit cycle dynamics

energy decomposition analysis iea model versus other methods abstract in energy decomposition analysis the international energy agency iea model which is based on the laspeyres index method is included in a recent international collaborative initiative on energy indicators for sustainable development for possible adoption iaea 2005 energy indicators for sustainable development guidelines and methodology international atomic energy agency vienna www pub iaea org mtcd publications pdf pub1222 web pdf from an empirical analysis using the data of the united states we found that the residual term given by the iea model could be significant and that the estimates of the impacts of structure and intensity changes given by the model could be quite different from those given by other decomposition methods the residual term tends to be large when changes in structure and or energy intensity variables are significant since changes in these variables over time are generally larger in the developing countries than in the iea countries there is the question about whether the iea model is an appropriate decomposition method for the developing countries

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

analysis of co2 emissions in apec countries a time series and a cross sectional decomposition using the log mean divisia method abstract we decompose the changes of co2 emissions in apec countries over time as well as the differences of co2 emissions among three income groups of apec countries at a given period of time based on the logarithmic mean divisia decomposition approach among the major findings of the paper the growth in per capita gdp and population are the two dominant contributors to the increase in co2 emissions in most cases furthermore energy efficiency and fuel switching are found to be the two most promising fields for possible cooperation between apec member countries

driving factors of carbon emissions embodied in china us trade a structural decomposition analysis abstract based on the environmental multi regional input output model this study employed structural decomposition analysis to investigate the driving factors of carbon emissions embodied in china us trade over the period of 1995 2009 effective driving factors were classified into six groups and each group included both factors at home and abroad the results show that factors trade structure of intermediate products at home and export market shares of final products at home presented the largest positive impacts to increments in carbon emissions embodied in chinese exports to the us while the majority of negative impacts was generated by changes in energy intensities at home the increment in carbon emissions embodied in us exports to china was mostly contributed by total demands abroad impacts of other driving factors were much smaller at the sectoral level both positive and negative impacts of driving factors were largely limited to a few sectors e g textiles products machinery transport equipment and electrical equipment here positive impacts were mostly contributed by export market shares of final products at home and total demands abroad and negative impacts were mainly contributed by energy intensities at home policy implications deduced from the results were discussed

water rights reform and water marketing australia vs the us west we consider the connection between water marketing and the modification of property rights to water in australia highlighting the australian s distinctiveness through a contrast with water rights in the western us especially california australia started out the same as california but in the 1880s it abandoned california s system and adopted a new approach ending the common law property right to water and creating a statutory right that could be modified by administrative fiat this shifted the arena for dispute resolution from courts to parliaments it eliminated the seniority inherent in appropriative water rights and it sidelined issues of third party impacts another difference was the tight control of irrigation institutions by state governments and the national government s willingness to intervene in state and local water management australian water reform was wrapped in politics when there were successes this is because the politics were managed adroitly when political challenges proved insurmountable reform stalled

how can chile move away from a high carbon economy abstract this paper quantitatively evaluates the performance of chile s co2 emissions between 1991 and 2013 using a complete decomposition technique to examine emissions and their components a decomposition analysis based on log mean divisia index method lmdi i was conducted six decomposition factors were considered carbon intensity effect ci res penetration effect res energy intensity effect ei economy structure effect es income effect yp and population effect p to know how these factors could influence each other in the future the innovative accounting approach iaa was used including forecast error variance decomposition and impulse response functions irfs these two methodologies allow us to identify the drivers of co2 emission changes in the past 1991 2013 test policy measures and learn how these drivers could influence each other in the future to evaluate whether the current measures meet the paris commitments the lmdi analysis results show that the energy intensity factor is the main compensating factor of chile s co2 emissions and the only effect with a clear trend to aid the economy s decoupling iaa and ifrs results react similarly and confirm that carbon intensity reacts to shocks more significantly in the short term the reaction to res has the same and opposite behavior to shocks in es and yp to disappear in the long term

manufacturing energy use in eight oecd countries decomposing the impacts of changes in output industry structure and energy intensity this paper examines trends in manufacturing energy use in eight oecd countries decomposing the changes that occured between 1973 and 1987 into the effects of changes in aggregate manufacturing activity industry structure and energy intensities measured at the industry group level while manufacturing production grew in every country except the uk the rate of growth was variable from nation to nation structural change led to modest reductions in energy use in most countries although in norway structural change led to substantial growth in energy use the reduction in energy intensities was strikingly uniform across all nations ranging from 20 norway to 36 japan over the period of the analysis while other studies have used divisia decomposition techniques we use an alternative method based on laspeyres indices a comparison of the two techniques shows that they yield closely similar empirical results although the laspeyres approach is more easily interpreted while the interactions between changes in structure and intensity are arbitrarily assigned to the two factors by the divisia approach the lapeyres method yields interaction terms that explicitly account for such effects

a tale of two water markets in australia lessons for understanding participation in formal water markets water markets are promoted as a demand management strategy for addressing water scarcity although there is an increasing literature on the institutional preconditions required for successful formal water markets there has been less focus on understanding what drives participation after establishment of the basic enabling conditions participation can be measured in terms of either trading activity conducting either a permanent or temporary water trade and or trade volumes across time and market products australia s water markets in the southern and northern basins of the murray darling basin provide a notable example of a tale of two water markets offering insights about the economic policy levers that can drive participation across different hydrological irrigation and socioeconomic contexts key lessons include distribution of initial property rights in resource allocation the need to prepare for and seize opportunities to strengthen property rights and robust monitoring and compliance requirements all of which will reduce transaction costs and increase participation

decomposition of aggregate carbon intensity for freight trends from 10 oecd countries for the period 1971 1993 abstract historical patterns of aggregate carbon intensity from freight are different than those from other sectors while aggregate carbon intensity declined for all other sectors aggregate carbon intensity for freight increased the adaptive weighted divisia rolling base year index specification is applied to carbon emissions from the freight sector of 10 oecd countries for the period 1970 1993 increases in aggregate carbon intensity for nine of the countries range from less than 20 to over 150 and may be primarily attributed to shifts in modal structure toward more carbon intensive modes these increases in aggregate carbon intensity are driven primarily by an increase in activity which parallels the growth in gdp furthermore changes in fuel price and vehicle purchase taxes do not appear to be effective instruments for reducing energy consumption for this end use alternative policy options including less carbon intensive fuels and technologies and reduced congestion appear to be better choices

non parametric frontier approach to modelling the relationships among population gdp energy consumption and co2 emissions abstract in this paper a non parametric approach based in data envelopment analysis dea is proposed as an alternative to the kaya identity a k a impact this frontier method identifies and extends existing best practices population and gdp are considered as input and output respectively both primary energy consumption and greenhouse gas ghg emissions are considered as undesirable outputs several linear programming models are formulated with different aims namely a determine efficiency levels b estimate maximum gdp compatible with given levels of population energy intensity and carbonization intensity and c estimate the minimum level of ghg emissions compatible with given levels of population gdp energy intensity or carbonization index the united states of america case is used as illustration of the proposed approach
