co2 emissions energy consumption and economic growth in china a panel data analysis this paper examines the causal relationships between carbon dioxide emissions energy consumption and real economic output using panel cointegration and panel vector error correction modeling techniques based on the panel data for 28 provinces in china over the period 1995 2007 our empirical results show that co2 emissions energy consumption and economic growth have appeared to be cointegrated moreover there exists bidirectional causality between co2 emissions and energy consumption and also between energy consumption and economic growth it has also been found that energy consumption and economic growth are the long run causes for co2 emissions and co2 emissions and economic growth are the long run causes for energy consumption the results indicate that china s co2 emissions will not decrease in a long period of time and reducing co2 emissions may handicap china s economic growth to some degree some policy implications of the empirical results have finally been proposed

subcontracting and the survival of plants in the road construction industry a panel quantile regression analysis this paper investigates how subcontracting parts of contracted work shapes entrants success and survival we find that newly developed quantile regression approaches can be adapted to study survival of firms competing for government contracts in road construction the method is applied on a data set that includes patterns of firm entry exit and auction related information we find an apparent increase in the business life of firms who subcontract out part of their projects in texas these subcontracting effects appear to be more pronounced for firms with few or no options outside the industry and among firms who contract out part of their work to disadvantaged business enterprises

the sustainable supply chain network competition with environmental tax policies abstract this paper captures different environmental tax policies in a multi tiered supply chain network competition context we derive the governing equilibrium conditions for the noncooperative game theory models for each firm and provide the equivalent variational inequality formulations the numerical examples investigate the impacts of emission tax policies and product differentiation on the competing firms and compare the effects of different environmental policies flat emission tax rates progressive emission taxes and the government command and control regulations with emission standards on equilibrium product demands prices total emissions and overall profits the computational results indicate that the implementation of environmental tax policies along with an increase in consumers environmental concerns can not only motivate the firms to perform sustainable operations but also reduce the total carbon footprint furthermore the low cost progressive emission tax policies can be as effective as the high flat emission tax rate in terms of reduction in carbon footprint therefore the model developed in this paper can be used by the policymakers and the firms to evaluate the effects of different environmental tax policies in a supply chain competition context

a multivariate cointegrated modelling approach in testing temporal causality between energy consumption real income and prices with an application to two asian ldcs unlike previous studies on the casual relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multiple cointegration tests preceded by various unit root or nonstationarity tests we test for cointegration between total energy consumption real income and price level of two asian ldcs thailand and sri lanka nonrejection of cointegration between variables rules out granger noncausality and implies at least one way of granger causality either unidirectional or bidirectional secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample grangerexogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total

is the energy led growth hypothesis valid new evidence from a sample of 85 countries abstract the energy growth literature contains a large number of discussions on the causal relationship between energy consumption and economic growth the central debate focuses on whether energy consumption contributes or not to economic growth since it has direct implications for the formulation of strategic policies nevertheless current studies cannot provide a conclusive suggestion due to mixed causality results this inconclusive evidence is potentially attributed to model specifications and the stage of economic development of the countries under investigation hence this study attempts to empirically re investigate the validity of the energy led growth hypothesis using a different model specification and different stages of economic development for 85 selected countries around the globe overall although the causality results are mixed among countries we do find a systematic pattern in particular granger causality models with three and four variables are more likely to support the hypothesis compared to their counterparts that contain only two variables in addition both developed and developing countries are more likely to support the energy led growth hypothesis compared to the less developed or low income countries therefore causality results are very sensitive to the choice of the model specification along with the stages of economic development finally energy conservation policies should only focus on low income countries as these policies may not retard the process of economic growth

exploring the effects of energy consumption on output per worker a study of albania bulgaria hungary and romania in this article we explore the long run cointegration between output capital and energy consumption in per worker terms for albania bulgaria hungary and romania we use the augmented solow 1956 model and the ardl bounds procedure pesaran et al 2001 to examine the short run and long run effects of energy and capital on output in per worker terms we also conduct causality test using the toda and yamamoto 1995 non causality procedure our results show the existence of long run cointegration between output per worker and energy per worker for all the four countries we find that energy per worker have a dynamic short run positive effect in albania 0 37 bulgaria 0 25 hungary 0 36 and romania 0 68 and a long run positive effect in bulgaria 0 32 and romania 0 63 which duly indicate that energy consumption has a momentous long run effect in these two countries the causality results indicate a unidirectional causation from output per worker to energy per worker for all the four countries and from capital per worker to energy per worker for albania and romania consequently a balance between effective energy consumption and sound energy conservation policies are likely to support economic growth in the four countries

natural gas consumption and economic growth the role of foreign direct investment capital formation and trade openness in malaysia the objective of this paper is to reinvestigate the relationship between natural gas consumption and economic growth by including foreign direct investment capital and trade openness in malaysia for the period of 1971 2012 the structural break unit root test is employed to investigate the stationary properties of the series we have applied combined cointegration test to examine the relationship between the variables in the long run for robustness sake the ardl bounds testing method is also employed to test for a possible long run relationship in the presence of structural breaks we note the validity of cointegration between the variables natural gas consumption foreign direct investment capital formation and trade openness have positive influence on economic growth in malaysia the results support the presence of feedback hypothesis between natural gas consumption and economic growth foreign direct investment and economic growth and natural gas consumption and foreign direct investment the policy implications of these results are provided

energy consumption at business cycle horizons the case of the united states in this paper we propose a simple extension to a keynesian type macro model by augmenting it with energy consumption we show the relationship between energy consumption and output in a macroeconomic setting and ask the question do permanent shocks dominate changes in energy consumption and output at business cycle horizons for the united states to achieve the goal of this paper we undertake a variance decomposition analysis of shocks based on a common trend and common cycle framework within a vector error correction model our main finding is that permanent shocks explain the bulk of the variations in energy consumption and output at business cycle horizons for the united states

imposing emission trading scheme on supply chain separate and joint implementation abstract in response to global warming it is urgent to control and reduce greenhouse gas ghg emissions especially from the supply chain perspective the most often discussed topic in this domain indicates that emission trading scheme ets could be employed as one of policy instruments for supply chain emissions management via mathematical models scholars have shown that the employment of emission trading is affecting supply chain performances both environmental and economic in different levels however previous literature focus on the cost effectiveness analysis only from the mathematical aspect to provide policy makers and companies with the theoretical bases on this hot topic it is significant to discuss how ets one of market based instruments could be imposed in the context of supply chain from the mechanical point of view by incorporating ideas from relevant literature this paper generates two concepts modes in imposing ets on supply chain jointly imposed supply chain emission trading e g jointly imposed sc ets and separately imposed supply chain emission trading e g separately imposed sc ets it illustrates the working principles of both concepts modes and conducts a sandbox example to analyze the cost effectiveness of them furthermore this paper discusses the challenges and opportunities of implementing two modes from practical aspects results of quantitative analysis and discussion show that for the sake of both policy makers and supply chain companies the separately imposed sc ets allowing selling permits would be so far the better mode to manage supply chain ghg emissions compared to the jointly imposed sc ets

has energy efficiency performance improved in china non energy sectors evidence from sequenced hybrid energy use tables we conduct a comparative analysis of two energy efficiency indicators for china heating value energy intensity hei and economic value energy intensity mei we formulate 1997 2002 2007 2012 hybrid energy comparable sequence use tables in an input output accounting framework and compare the two indicators using a randomized block anova the results show that meis and heis have significantly different variability patterns among sectors and are evolutionarily divergent over time the directional changes in mei and hei are found to be inconsistent at both the sectoral and national levels a further analysis with a lmdi index decomposition model shows that the difference between hei lmdi and hei lmdi is principally caused by energy prices based on the evidence from the two indicators and their relationship to energy prices we are unconvinced about china s purported improvements in energy efficiency in recent years

outside options another reason to choose the first price auction abstract in this paper we study equilibrium and experimental bidding behaviour in first price and second price auctions with outside options we find that bidders do respond to outside options and to variations of common knowledge about competitors outside options however overbidding in first price auctions is significantly higher with outside options than without first price auctions yield more revenue than second price auctions this revenue premium is significantly higher with outside options in second price auctions the introduction of outside options has only a small effect

how costly is affirmative action government contracting and california s proposition 209 abstract this paper investigates the effect of disadvantaged business enterprise subcontractor goals on the winning bids for highway construction contracts using california s proposition 209 which prohibited the consideration of race or gender in awarding state funded contracts after proposition 209 prices on state funded contracts fell by 5 6 relative to federally funded projects for which preferences still applied most of the price decline after proposition 209 resulted from the mix of subcontractors employed which seems to arise from the higher costs of firms located in high minority areas finally short run barriers to entry and expansion may increase the cost of affirmative action

the effect of information on the bidding and survival of entrants in procurement auctions in government procurement auctions of construction contracts entrants are typically less informed and bid more aggressively than incumbent rms this bidding behavior makes them more sus ceptible to losses aecting their prospect of survival in april of 2000 the oklahoma department of transportation started releasing the internal cost estimates to complete highway construction projects using newly developed quantile regression approaches this paper examines the impact of the policy change on aggressive entrants first we nd that the information release eliminates the bidding dierential between entrants and incumbents attributed to informational asymmetries second we argue that the policy change aects the prospects of survival of entrants in the market we nd that those who used to exit the market relatively soon are now staying 37 percent longer while at the median level bidding duration increased by roughly 68 percent the policy has the potential to encourage entry in government procurement auctions and thus increase competition

decomposition of us manufacturing energy intensity and elasticities of components with respect to energy prices this paper proposes an analysis of changes in the us manufacturing energy intensity between 1974 and 1998 the starting point is a three term decomposition of an intensity index which evaluates annually the respective contributions of changes in industrial structure efficiency gains at the sectoral level and substitution between energy resources to aggregate productivity improvements then we study the time paths followed by each of these three components using spectral analysis techniques we show that they behave very differently as the structural influence plays a part mainly in the short run substitution between energy resources acts principally in the long run and the changes in sectoral intensity cause both trend variations and cyclical ones finally we focus on the effect of energy price evolution on each of the three components allowing energy price rises and decreases to have asymmetric effects we estimate both the long run impacts and the short run adjustments

aggregation and the role of energy in the economy methods for investigating the role of energy in the economy involve aggregating different energy flows a variety of methods have been proposed but none has received universal acceptance this paper shows that the method of aggregation has crucial effects on the results of the analysis we review the principal assumptions and methods for aggregating energy flows the basic heat equivalents approach economic approaches using prices or marginal product for aggregation emergy analysis and thermodynamic approaches such as exergy we argue that economic approaches such as the index or marginal product method are superior because they account for differences in quality among fuels we apply various economic approaches in three case studies in the us economy in the first we account for energy quality to assess changes in the energy surplus delivered by the extraction of fossil fuels from 1954 to 1992 the second and third case studies examine the importance of energy quality in evaluating the relation between energy use and gdp first a quality adjusted index of energy consumption is used in an econometric analysis of the causal relation between energy use and gdp from 1947 to 1996 second we account for energy quality in an econometric analysis of the factors that determine changes in the energy gdp ratio from 1947 to 1996 without adjusting for energy quality the results imply that the energy surplus from petroleum extraction is increasing that changes in gdp drive changes in energy use and that gdp has been decoupled from between aggregate energy use all of these conclusions are reversed when we account for changes in energy quality 2000 elsevier science b v all rights reserved

oil and the macroeconomy since world war ii all but one of the u s recessions since world war ii have been preceded typically with a lag of around three fourths of a year by a dramatic increase in the price of crude petroleum this does not mean that oil shocks caused these recessions evidence is presented however that even over the period 1948 72 this correlation is statistically significant and nonspurious supporting the proposition that oil shocks were a contributing factor in at least some of the u s recessions prior to 1972 by extension energy price increases may account for much of post opec macroeconomic performance

energy consumption and economic growth in the next 11 countries the bootstrapped autoregressive metric causality approach abstract departing from previous literature using bootstrapped autoregressive metric causality approach which is more robust against non stationarity and break problems than lag augmented tests this study analyzes causal relation between economic growth and energy consumption in the next 11 countries estimating a trivariate model consisting of gdp per capita energy consumption per capita and gross capital formation it was found that the neutrality hypothesis is valid for all of the countries except for turkey these findings imply that energy conservation oriented policies should be implemented in bangladesh egypt indonesia iran korea mexico pakistan and philippines in the case of turkey a unidirectional causal nexus was found from energy consumption to economic growth since the growth hypothesis is valid energy conservation policy poses an obstacle for economic growth in turkey

design of sustainable supply chains under the emission trading scheme increase in environmental concerns together with legislations are forcing industries to take a fresh look at the impact of their supply chain operations on the environment this paper introduces a mixed integer linear programming based framework for sustainable supply chain design that considers life cycle assessment lca principles in addition to the traditional material balance constraints at each node in the supply chain indeed the framework distinguishes between solid and liquid wastes as well as gaseous emissions due to various production processes and transportation systems the framework is used to evaluate the tradeoffs between economic and environmental objectives under various cost and operating strategies in the aluminum industry the results suggest that current legislation and emission trading schemes ets must be strengthened and harmonized at the global level in order to drive a meaningful environmental strategy moreover the model demonstrates that efficient carbon management strategies will help decision makers to achieve sustainability objectives in a cost effective manner

subcontracting and competitive bidding on incomplete procurement contracts this article examines the impact of incomplete contracts on subcontracting and the design of procurement auctions i estimate the effect of ex post contract revisions on unit costs for both subcontracted and in house performed work items on bridge projects procured by the california department of transportation i model a scoring auction showing how ex post revisions skew bidding decisions and estimate unit costs from bid data using the method of sieve estimation the results highlight the cost implications of incomplete contracting frictions subcontracting decisions and bidding distortions in conclusion i propose alternative auction mechanisms that could improve outcomes

dynamic auction environment with subcontracting this article provides evidence on the role of subcontracting in the auction based procurement setting with private cost variability and capacity constraints we demonstrate that subcontracting allows bidders to modify their costs realizations in a given auction as well as to control their future costs by reducing backlog accumulation restricting access to subcontracting raises procurement costs for an individual project by 12 and reduces the number of projects completed in equilibrium by 20 the article explains methodological and market design implications of subcontracting availability

entry and subcontracting in public procurement auctions we empirically study how the interplay between entry and subcontracting choices is affected by the use of different auction formats in public procurement the difference in differences strategy used exploits a data set of auctions for public works run alternately under first price and average bid auctions we find that the use of first price auctions causes a marked decline in both entry and subcontracting we also find that the type of firms entering first price auctions changes with firms becoming more likely to bid jointly with other firms in ad hoc joint ventures data as supplemental material are available at http dx doi org 10 1287 mnsc 2014 2071 this paper was accepted by teck hua ho behavioral economics

global reverse supply chain redesign for household plastic waste under the emission trading scheme with increasing global resource scarcity waste becomes a resource that can be managed globally a reverse supply chain network for waste recycling needs to process all the waste with minimum costs and environmental impact as re processing of waste is one of the major sources of pollution in the recycling processes a mechanism is needed to control and reduce the emission impact in the re processing as a key to facilitate the globalized reverse supply chain and avoid spreading pollutants overseas emission trading schemes ets can function as policy instruments for controlling emissions the ets introduces a trade off between the economic efficiency and the environmental impacts ets has been implemented in europe and is developing rapidly in china too the aim of the research is to re design a reverse supply chain from a global angle based on a case study conducted on household plastic waste distributed from europe to china emission trading restrictions are set on the processing plants in both europe and china we modeled a network optimization problem using integer programing approach allowing the re allocation of intermediate processing plants under emission trading restrictions optimization results show that global relocation of re processors leads to both a reduction of total costs and total transportation emission ets applied to re processors further helps to reduce emissions from both re processing and transportation sectors carbon cap should be carefully set in order to be effective with a given carbon cap the model also shows the effective carbon price range these results give an insight into the feasibility of building a global reverse supply chain for household plastic waste recycling and demonstrate the impact of ets on the network design

economic growth energy conservation and emissions reduction a comparative analysis based on panel data for 8 asian pacific countries this study was conducted to evaluate the causality between energy consumption gdp growth and carbon emissions for eight asia pacific countries from 1971 to 2005 using the panel data the results indicate that there are long run equilibrium relationships between these variables additionally causality from energy consumption to co2 emissions was observed generally but there were some opposite relationships also parameter estimations of the panel data model indicate that there are great differences in the carbon emissions the efficiencies of energy use carbon emissions of unit gdp and unit energy consumption between developed and developing countries the base carbon emissions per capita energy consumption and efficiency of energy use in developing countries are far lower than in developed countries however the co2 emissions per unit of energy use is higher although developing countries may reduce their co2 emission per unit energy use total energy consumption will rise rapidly with economic development thus developing countries must determine how to undergo economic growth while conserving energy and reducing emissions to respond to global climate change it is necessary to develop innovative technology for energy use transform the energy structure and conduct the clean development mechanism

exploring the relationship between energy use and economic growth with bivariate models new evidence from g 7 countries abstract there is a rapidly growing literature on the interaction between energy use and economic development with many analysts drawing policy conclusions on the basis of granger causality tests that involve only an energy and an economic variable this paper attempts to demonstrate empirically that such studies although useful for certain applications may be of limited use for policy purposes after outlining theoretical and methodological issues associated with such approaches i apply bivariate energy economy causality tests for canada france germany italy japan the united kingdom and the united states using aggregate and sectoral data and three different modern econometric methods the results which are often contradictory or economically implausible illustrate explicitly that one should be cautious when drawing policy implications with the aid of bivariate causality tests on small samples i therefore underline the importance of utilizing as large sample sizes as possible and using multivariate models which are closer to economic theory accommodate several mechanisms and causality channels and provide a better representation of real world interactions between energy use and economic growth

energy consumption in china and underlying factors in a changing landscape empirical evidence since the reform period abstract in recent decades the phenomenal growth in the chinese economy has created increasing energy consumption this is the first study analysing energy consumption in china considering economic social and political dimensions of globalisation along with the effects from trade and financial sectors the time period covers the full trajectory since the start of economic reform until recent times in this respect we use the konjunkturforschungsstelle kof globalisation index to explore the dynamic link between economic growth financial development trade and various dimensions of globalisation and energy consumption modern time series econometric techniques are used in establishing stationarity long run dynamics and causality of the series the findings suggest that globalisation decreases energy consumption in the short run but increases it in the long run however the effect of financial development on energy consumption in china is opposite to the globalisation effect on energy consumption granger causality reveals a feedback effect between economic globalisation and financial development globalisation in china can only reduce energy consumption if china develops its financial sector to a greater extent in future china should invest in its financial sector and low carbon energy alternatives to achieve sustainable development prevention of energy shortfalls and cleaner environment would assist in bridging the gap both from social and political aspects to ensure china benefits significantly with high economic growth in this asian century

electricity consumption and economic growth in china abstract this paper applies the error correction model to examine the causal relationship between electricity consumption and real gdp for china during 1971 2000 our estimation results indicate that real gdp and electricity consumption for china are cointegrated and there is unidirectional granger causality running from electricity consumption to real gdp but not vice versa in order to overcome the constraints on electricity consumption the chinese government has to speed up the nation wide interconnection of power networks to upgrade urban and rural distribution grids and to accelerate rural electrification

energy and economic growth in the usa a multivariate approach abstract this paper examines the causal relationship between gdp and energy use for the period 1947 90 in the usa the relationship between energy use and economic growth has been examined by both biophysical and neoclassical economists in particular several studies have tested for the presence of a causal relationship in the granger sense between energy use and economic growth however these tests do not allow a direct test of the relative explanatory powers of the neoclassical and biophysical models a multivariate adaptation of the test vector autoregression var does allow such a test a var of gdp energy use capital stock and employment is estimated and granger tests for causal relationships between the variables are carried out although there is no evidence that gross energy use granger causes gdp a measure of final energy use adjusted for changing fuel composition does granger cause gdp

firm entry and exit in the canadian manufacturing sector 1970 1982 this paper measures the importance of entry and exit to the canadian manufacturing sector in the 1970s it focuses on the size of entrants as they move from a stage of infancy to adolescence the exit rates of births their length of life and the growth path of entrants are presented distinctions are made between greenfield and merger entry while entrants are small at birth the cumulative effect of successive cohorts of entrants in the 1970s adds up to a significant fraction of all firms and total sales by 1979

energy growth conundrum in energy exporting and importing countries evidence from heterogeneous panel methods robust to cross sectional dependence abstract this article uses the panel methods for energy exporting and importing countries that discuss the heterogeneity and cross sectional dependence in investigating the linkages between energy consumption and economic growth the findings of the study suggest that the energy consumption is an important input not only in the energy importing but also in energy exporting countries furthermore the results of the present paper suggest that the policy options should be different for the different countries in the back drop of heterogeneous slope coefficients

the relationship between energy and gnp further results this paper reexamines the casuality between gnp and energy consumption by using updated us data for the period 1947 1979 as a secondary contribution we investigate the causal relationship between energy consumption and employment applying sims technique we find no causal relationship between gnp and energy consumption we find further that there is a slight unidirectional flow running from employment to energy consumption economic interpretations of the empirical results are also presented

energy efficiency and the slump in labour productivity in the usa energy consumption is included in an aggregate cobb douglas production function for the usa the data suggest that energy conservation has not reduced the growth rate for real gnp by more than 0 3 percentage points and that less than one fifth of the overall slump in labour productivity since 1973 should be attributed to higher energy prices

residential and non residential electricity dynamics abstract this paper uses u s panel data to instrument and examine the dynamics of electricity within the world market while separating between both residential and non residential electricity consumptions during the time period of 1990 2014 to better assess the true differences within each causal relationship all panel data has been separated into one full panel and three subpanels of high middle and low income the empirical framework used consists of various tests that identify the existence of cross sectional dependency a pesaran panel unit root test a westerlund panel cointegration test and the dumitrescu hurlin method of the granger causality test furthermore this paper utilizes dols to estimate any long run elastic relations between real gdp and residential or non residential electricity consumption based on the results this paper determines that no long run relationship exists between non residential electricity consumption and economic growth throughout and that the relationship between residential electricity consumption and economic growth possesses unit elastic behavior in the long run other findings throughout imply causality moves from economic growth in the direction of residential electricity consumption for all panels

the impact of carbon policies on supply chain design and logistics of a major retailer abstract the energy used to move freight comprised about 17 of all the energy consumed in the united states in 2010 this percentage was an increase from 8 7 in 1970 even though fuel efficiency gradually improved over the period one major reason of this phenomenon is that the longer supply chains of many industries caused by globalization increase freight movement various carbon policies have been discussed and even implemented for some industry sectors in the european union to reduce carbon emissions however the emissions of surface transportation have not been well studied this paper investigates three of the most common carbon policies carbon emission tax inflexible cap and cap and trade the impact on a company may include the redesign of its supply chains and different choices of transportation modes truck rail or waterway this paper proposes optimization models for major retailers who make a huge contribution to freight movement to design their supply chains under various carbon policies the results from the models can help policy makers to predict the impact of policies on overall emissions in the freight transportation sector the model may also be incorporated into the integrated assessment models for climate change analyses furthermore a sensitivity analysis is conducted to study the impact of the policy parameters on carbon emissions and logistics cost this research uses the supply chain of a major u s retailer i e wal mart to demonstrate how to use the models and conduct the sensitivity analysis in order to realize significant emission reduction a redesign of supply chains of major retailers is necessary and will be triggered only by a high carbon tax rate a high carbon price or a very strict carbon cap which all may involve high social and or economic complexity numerical experiments show that different policies have different impacts on the costs and the effectiveness of emission reduction how to choose policy parameters is critical to the effectiveness of a carbon policy the different sensitivity also implies different challenges during the implementation of the policies such as the high cost preventing retailers from accepting any carbon taxes and the difficulty of reaching an agreement on the carbon caps between retailers and policy makers

the influence of energy consumption of china on its real gdp from aggregated and disaggregated viewpoints abstract this paper investigated the causal relationship between energy consumption and gross domestic product gdp in china at both aggregated and disaggregated levels during the period of 1978 2009 by using a modified version of the granger 1969 causality test proposed by toda and yamamoto 1995 within a multivariate framework the empirical results suggested the existence of a negative bi directional granger causality running from aggregated energy consumption to real gdp at disaggregated level of energy consumption the results were complicated for coal empirical findings suggested that there was a negative bi directional granger causality running from coal consumption to real gdp however for oil and gas empirical findings suggested a positive bi directional granger causality running from oil as well as gas consumption to real gdp though these results supported the feedback hypothesis the negative relationship might be attributed to the growing economy production shifting towards less energy intensive sectors and excessive energy consumption in relatively unproductive sectors the results indicated that policies with reducing aggregated energy consumption and promoting energy conservation may boost china s economic growth

scale economies and the dynamics of recurring auctions we analyze the dynamics of a game of sequential bidding in the presence of stochastic scale effects either economies or diseconomies of scale we show that economies of scale give rise to declining expected equilibrium prices whereas the converse is not generally true moreover first and second price auctions are not always revenue equivalent economies of scale make second price auctions more profitable for the seller whereas revenue equivalence may be preserved in the case of diseconomies

on the application of input output analysis to energy issues abstract the paper develops a static input output i o framework for analysing energy issues in the short run in addition to reviewing the conventional static i o model the paper discusses two problems in its applications i interdependence between the projected sectoral output in the multiplier analysis and ii definition of substitution effect in changing the energy input coefficient the corresponding modifications will be analysed an unconventional supply driven i o model is also discussed here in order to improve the completeness on the application of the input output model

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

income and emission a panel data based cointegration analysis this paper presents the results of an investigation of the causality issue of incomeemission relationship based on time series econometric techniques of unit root test cointegration and related error correction model for a panel data set here the nature of causality between per capita co2 emission pcco2 and per capita gdp pcgdp has been examined using a cross country panel data set covering 88 countries for the period 1960 90 using the panel unit root test procedure of im et al 1997 ips we have found that the hypothesis of unit root i e non stationarity of the time series of pcgdp and pcco2 can not be rejected for individual country groups as both the variables are found to follow i 1 process we next have performed the panel data co integration test and finally we have estimated the ecm for these country groups for which significant income emission cointegration was obtained to explore the nature of dynamics implicit in the given panel data set our findings suggest that there is more or less a bi directional causal relationship between income pcgdp and co2 emission pcco2 for africa central america america as a whole eastern europe western europe europe as a whole and the world as a whole that means the movement of the one variable directly affects the other variable through a feedback system thus the policy makers should be cautious to make proper decision about the control of emission level

disadvantaged business enterprise goals in government procurement contracting an analysis of bidding behavior and costs programs that encourage the participation of disadvantaged business enterprises dbe as subcontractors have been a part of government procurement auctions for over three decades in this paper we examine the impact of a program that requires prime contractors to subcontract out a portion of a highway procurement project to dbe firms we study how dbe subcontracting requirements affect bidding behavior in federally funded projects within a symmetric independent private value framework we use the equilibrium bidding function to obtain the cost distribution of firms undertaking projects either with or without subcontracting goals we then use nonparametric estimation methods to uncover and compare the cost of firm bidding on a class of asphalt projects related to surface treatment in texas the analysis shows little differences in the cost structure between projects that have subcontracting goals and those that do not

defining total energy use in economic studies does the aggregation approach matter abstract in economic models the aggregate consumption of energy resources is normally expressed either in terms of its total heating value e g btus or barrels of oil equivalent or in terms of its economic value e g divisia indices or total expenditures for most major oecd countries we find that it matters little whether various energy resources consumed in the industrial sector are aggregated in terms of their heating value or their economic value similar trends emerge regardless of which measure is adopted consequently as a practical matter macroeconomic and energy modeling efforts need not be too concerned about which measure of total energy usage is adopted the prominent exceptions are the united states and mexico where measures of total industrial sector energy use based on heating values and economic values diverge greatly due to some unique trends in electrification and energy prices consequently attention to aggregation issues may be an important consideration in efforts to model the energy consumed in the us or mexico

breaks and trends in oecd countries energy gdp ratios this paper uses the econometrics of endogenous structural breaks to examine changes in energy intensity trends for oecd countries over 1960 2009 nearly all oecd countries currently have significant negatively trending energy gdp ratios but for several countries those negative trends are recent and two countries have recent significant positive trends for several countries energy intensity had a significant positive trend followed by a break and then a significant negative trend those break dates however appear to have little to do with level of development gdp per capita alternatively the volatile energy prices of the 1970s and early 1980s played a role in many of the countries that experienced inverted v breaks these findings have implications for future modeling and forecasting of energy consumption as well as for the role of energy price policy in developed and developing countries

digitalization and energy consumption does ict reduce energy demand abstract this article investigates the effect of digitalization on energy consumption using an analytical model we investigate four effects 1 direct effects from the production usage and disposal of information and communication technologies ict 2 energy efficiency increases from digitalization 3 economic growth from increases in labor and energy productivities and 4 sectoral change tertiarization from the rise of ict services the analysis combines empirical and theoretical findings from debates on decoupling energy consumption from economic growth and from debates on green it and ict for sustainability our main results effects 1 and 3 tend to increase energy consumption effects 2 and 4 tend to decrease it furthermore our analysis suggests that the two increasing effects prevail so that overall digitalization increases energy consumption these results can be explained by four insights from ecological economics a physical capital and energy are complements in the ict sector b increases in energy efficiency lead to rebound effects c ict cannot solve the difficulty of decoupling economic growth from exergy d ict services are relatively energy intensive and come on top of former production in future digitalization can only boost sustainability when it fosters effects 2 and 4 without promoting effects 1 and 3

energy consumption and economic growth in vietnam abstract this study attempts to analyse the relationship between energy consumption and economic growth in vietnam using the neoclassical solow growth framework for the 1971 2011 period the concept and methods of cointegration and granger causality are used to establish the relationship between the variables of interest our results confirm the existence of cointegration among the variables in particular energy consumption fdi and capital stock were found positively influence economic growth in vietnam the granger causality test revealed unidirectional causality running from energy consumption to economic growth hence vietnam is an energy dependent economy and any energy or environment policy drawn up in an attempt to conserve energy will jeopardise the process of economic development in vietnam for this reason the renewable energy policy should be given attention to provide sufficient supplies of energy to speed up economic expansion investment in r d may be required to incentivise private public institutions to engage in this innovation while the awareness for energy saving policy among public could be integrated to meet social economic development

will the aggregation approach affect energy efficiency performance assessment abstract aggregate energy is usually measured in the linear weighted summation of various energy types based on thermal dynamics laws this measurement is scientific and acceptable in the physics or energy engineering world however it implicitly assumes that all energy types are perfectly substitutable and thus may result in distorted conclusions in energy economy research in economics world production factors are usually non linearly aggregated using divisia approach which is derived from microeconomic theory and considers the heterogeneity and imperfect substitutability among various energies using which ruler to measure the aggregate energy the linear one or the others will certainly affect the conclusions and energy saving incentives of the economic agents inequitable energy aggregations may bring out speculations or discouraged behaviors according to china s current provincial energy efficiency performance assessment policy the central government assigned the target of reducing the national aggregate energy intensity by 20 in 2006 2010 to provincial authorities in 2006 and in july 2011 the central government formally released the provincial assessment results based on conventional linear aggregation approach coal equivalent our re examination review this policy and show that the official results are quite different to that based on divisia approach from the perspective of economics some local performances are overestimated and others are underestimated to raise the equity and incentive compatibility of the assessment we suggest the central take the imperfect substitutability or energy structure changes into consideration we also discuss the difficulties and deficiencies when using divisia aggregate approach

small business set asides in procurement auctions an empirical analysis as part of public procurement many governments adopt small business programs to pro vide contract opportunities for businesses often with preferences for firms operated by mem bers of groups designated as disadvantaged the redistribution arising from such programs however can introduce significant added costs to government procurement budgets in this paper the extent to which small business set asides increase government procurement costs is examined the estimates employ data on japanese public construction projects where approximately half of the procurement budget is set aside for small and medium enterprises smes applying a positive relationship between profitability and firm size obtained by the non parametric estimation of asymmetric first price auctions with affiliated private values a counterfactual simulation is undertaken to demonstrate that approximately 40 percent of smes would exit the procurement market if set asides were to be removed surprisingly the resulting lack of competition would increase government procurement costs more than it would offset the production cost inefficiency

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

an analysis of co2 emissions of japanese industries during the period between 1985 and 1995 this paper examines the factors that have an effect on co2 emissions produced by japanese industries between 1985 and 1995 by using input output tables the effects of environmental technological changes etc and production technological changes ptc on co2 emissions are considered separately furthermore backward and forward linkage effects in each sector that shows the extent to which each sector spreads or receives co2 emissions impacts across all of sectors will be calculated the results show that both types of technologies contributed to a decrease in co2 emissions during the bubble economy of the late 1980s but not during the recession of the early 1990s trade factors succeeded in decreasing co2 emissions in both periods thus trade structures facilitated the turning of japan into a net importer of co2 emissions between 1985 and 1995 the backward and forward linkage effects also decreased during the boom of the late in 1980s but not the recession of the early 1990s while the chemical products and electrical machinery sectors continued to reduce both effects this indicates that both sectors were relatively successful in decreasing their co2 emissions impacts between 1985 and 1995

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

industrial co2 emissions from energy use in korea a structural decomposition analysis abstract this paper attempts to quantify energy consumption and co 2 emissions in the industrial sectors of korea the sources of the changes in co 2 emissions for the years 1990 2003 are investigated in terms of a total of eight factors through input output structural decomposition analysis changes in emission coefficient caused by shifts in energy intensity and carbon intensity changes in economic growth and structural changes in terms of shifts in domestic final demand exports imports of final and intermediate goods and production technology the results show that the rate of growth of industrial co 2 emissions has drastically decreased since the 1998 financial crisis in korea the effect on emission reductions due to changes in energy intensity and domestic final demand surged in the second period 1995 2000 while the impact of exports steeply rose in the third period 2000 2003 of all the individual factors economic growth accounted for the largest increase in co 2 emissions the results of this analysis can be used to infer the potential for emission reduction in korea

energy efficiency achievements in china s industrial and transport sectors how do they rate abstract china is experiencing intensified industrialisation and motorisation in the world s largest emerging economy energy efficiency is expected to play a critical role in the ever rising demand for energy based on factual overviews and numerical analysis this article carries out an in depth investigation into the effectiveness of policies announced or implemented in recent decades targeted at energy conservation in the energy intensive manufacturing and transportation sectors it highlights nine energy intensive sectors that achieved major improvements in their energy technology efficiency efforts under the umbrella of the 11th five year plan these sectors performances reflect the effectiveness of china s energy conservation governance numerous actions have been taken in china to reduce the road transport sector s demand for energy and its ghg emissions by implementing fuel economy standards promoting advanced energy efficient vehicles and alternative fuels coal based energy saving technologies especially industrial furnace technologies are critical for china s near and medium term energy saving in the long run renewable energy development and expanding the railway transport system are the most effective ways to reduce energy use and ghg emissions in china fuel economy standards could reduce oil consumption and ghgs by 34 35 per cent

the importance of energy quality in energy intensive manufacturing evidence from panel cointegration and panel fmols this paper expands on the panel gdp energy cointegration modeling literature it does so by using data disaggregated along sectoral lines and adjusting energy consumption for the quality of the energy source e g electricity is of higher quality than oil which is of higher quality than coal in order to examine the role of energy quality in the five most energy intensive manufacturing sectors iron and steel non ferrous metals non metallic minerals chemicals and pulp and paper the database was constructed by combing energy consumption and energy price data to construct the energy quality index from the iea with economic data value added labor employed and physical capital from the oecd s structural analysis database in addition to finding the variables analyzed are panel i 1 and cointegrated for each sector based panel the long run elasticity estimates from panel fmols indicate the importance of energy quality primarily the shift toward the use of high quality electricity in these energy intensive manufacturing sectors in each case the elasticity for energy quality is greater than that for conventionally measured energy consumption sometimes orders of magnitude greater indeed the elasticity of conventionally measured energy consumption is insignificant to very small for three of the five sectors also when using the energy quality measure the importance of energy consumption relative to the other production factors stands out such results are useful for both energy gdp cointegration causality modelers and cge modelers who may need to estimate elasticities

carbon pricing versus emissions trading a supply chain planning perspective abstract carbon pricing taxes and carbon emissions trading are two globally practiced carbon regulatory policy schemes this paper presents an analytical supply chain planning model that can be used to examine the supply chain performance at the tactical operational planning level under these two policy schemes model implementation and analyses are completed using actual data from a company operating in australia where these environmental regulatory policies are practiced numerical results provide important managerial and practical implications and policy insights in particular the results show that there are inflection points where both carbon pricing and trading schemes could influence costs or emissions reductions an erratic nonlinear emissions reduction trend is observed in a carbon pricing scheme as the carbon price increases steadily whereas emissions reduction in a carbon trading scheme follows a relatively linear trend with a nonlinear cost increase overall a carbon trading mechanism although imperfect appears to result in better supply chain performance in terms of emissions generation cost and service level even though a carbon tax may be more worthwhile from an uncertainty perspective as emissions trading costs depend on numerous uncertain market conditions

the impact of public information on bidding in highway procurement auctions a number of papers in the theoretical auction literature show that the release of information regarding the seller s valuation of an item can cause bidders to bid more aggressively this widely accepted result in auction theory remains largely untested in the empirical literature recent theoretical work has also shown that this effect can be more pronounced in auctions with larger common cost uncertainty we examine the impact of a policy change by the oklahoma department of transportation that led to the release of the state s internal estimate of the costs to complete highway construction projects we perform a differences in differences analysis comparing bidding in texas a state that had a uniform policy of revealing the same information all throughout the period of analysis to bidding in oklahoma our results show that in comparison to texas auctions the average bid in oklahoma fell after the change in engineers cost estimate ece policy this decline in bids was even larger for projects where the common uncertainty in costs is greater moreover the within auction standard deviation of bids fell after the change in ece policy with the most significant decline observed again in projects with greater common cost uncertainty

the impact of carbon pricing on a closed loop supply chain an australian case study concerns about industrial and supply chain implications on our natural environment have existed for decades climate change and greenhouse gas emissions have caused countries to implement various instruments ranging from taxes permits and voluntary incentives to required regulatory policies given this environment we develop a unified optimization model for a closed loop supply chain in which the carbon emission is expressed in terms of dollar carbon cost this study is one of the first to evaluate the forward and reverse supply chain influences on the carbon footprint a comparative analysis is completed with a decomposition of cost and environmental influences across supply chain functions we utilize data from a company located in australia where the government is currently introducing a carbon pricing scheme we find that variations in cost and environmental impacts occur over ranges of carbon pricing characteristics and patterns of the numerical results over these ranges provide insights for corporate key strategies and potential additional government policies these results and implications are analyzed along with limitations and directions for future research

ex post assessment of china s industrial energy efficiency policies during the eleventh five year plan abstract china implemented a package of policies during the 11th five year plan 2006 2010 to improve industrial energy efficiency this assessment provides a methodology that establishes a causal relationship between policy implementation and energy conservation effects to enhance the confidence in the research findings this assessment applies two distinctive and independent approaches one top down and the other bottom up this assessment finds that industrial energy efficiency policies collectively achieved energy savings of 322 mtce 9 4 ej against the baseline scenario this accounted for 59 of the sector s total energy savings from 2006 to 2010 the remaining energy savings were realised through autonomous technology improvement 33 and sector level structural shift 8 correspondingly cumulative avoided co2 emissions realised through energy efficiency policies amounted to 760 million tons this assessment concludes that industrial energy efficiency policies were effective in realising energy conservation targets but energy conservation effects were not achieved in a cost effective way command and control measures were dominantly implemented with economic incentives and informational measures taking a complementary role while market based instruments did not play an important role as china is planning on implementing a nationwide emissions trading scheme special attention needs to be paid to policy interaction and coordination

energy conservation and sustainable economic growth the case of latin america and the caribbean this study examines the causal relationships among energy consumption economic growth and carbon dioxide emissions in twenty countries from latin america and the caribbean region the methodology includes the use of phillips and perron pp tests a cointegration model with vector error correction modeling vecm and vector autoregression var with granger causality the study concludes that of the twenty countries analyzed only in four of them will it be possible to implement energy conservation polices without affecting their economic growth four others are not able to consider an energy conservation policy with economic growth and the other twelve should focus on their economic growth before adopting any conservation policies energy efficiency was found in this region especially in the countries which have both cointegration and short term equilibrium

china s carbon dioxide emissions an interprovincial comparative analysis of foreign capital and domestic capital abstract against the background of china s further relaxation of foreign investment control and implementation of energy conservation and emissions reduction the data of 30 provinces in china from 2001 to 2015 were used to measure the carbon dioxide emissions levels foreign direct investment stock and domestic capital stock in various regions the impulse response function variance decomposition and panel causality test in the panel vector autoregressive model evaluated in detail the impact of foreign capital inflows domestic capital inputs and economic growth on co2 emissions in regions of different energy intensity the study found that on the whole foreign direct investment has no significant impact on china s carbon dioxide emissions china s carbon dioxide emissions are mainly driven by domestic investment and economic growth the sub regional analysis based on different energy intensities shows that in areas of low energy intensity and medium energy intensity foreign direct investment has a significant impact on co2 emissions and the contribution of foreign investment to co2 emissions is between 12 2 and 14 1 the panel causality test found that in the short term foreign direct investment and domestic capital have significant predictive effects on carbon dioxide in various regions

energy consumption and economic growth evidence from china at both aggregated and disaggregated levels using a neo classical aggregate production model where capital labor and energy are treated as separate inputs this paper tests for the existence and direction of causality between output growth and energy use in china at both aggregated total energy and disaggregated levels as coal oil and electricity consumption using the johansen cointegration technique the empirical findings indicate that there exists long run cointegration among output labor capital and energy use in china at both aggregated and all three disaggregated levels then using a vec specification the short run dynamics of the interested variables are tested indicating that there exists granger causality running from electricity and oil consumption to gdp but does not exist granger causality running from coal and total energy consumption to gdp on the other hand short run granger causality exists from gdp to total energy coal and oil consumption but does not exist from gdp to electricity consumption we thus propose policy suggestions to solve the energy and sustainable development dilemma in china as enhancing energy supply security and guaranteeing energy supply especially in the short run to provide adequate electric power supply and set up national strategic oil reserve enhancing energy efficiency to save energy diversifying energy sources energetically exploiting renewable energy and drawing out corresponding policies and measures and finally in the long run transforming development pattern and cut reliance on resource and energy dependent industries

co2 emissions in australia economic and non economic drivers in the long run abstractaustralia has sustained a relatively high economic growth rate since the 1980s compared to other developed countries per capita co2 emissions tend to be highest amongst oecd countries creating new challenges to cut back emissions towards international standards this research explores the long run dynamics of co2 emissions economic and population growth along with the effects of globalization tested as contributing factors we find economic growth is not emission intensive in australia while energy consumption is emissions intensive second in an environment of increasing population our findings suggest australia needs to be energy efficient at the household level creating appropriate infrastructure for sustainable population growth high population growth and open migration policy can be detrimental in reducing co2 emissions finally we establish globalized environment has been conducive in combating emissions in this respect we establish the beneficial effect of economic globalization

the dynamic links between energy consumption economic growth financial development and trade in china fresh evidence from multivariate framework analysis abstract this study investigates the relationship between energy use and economic growth by incorporating financial development international trade and capital as important factors of production function in case of china over the period of 1971 2011 the ardl bounds testing approach to cointegration was applied to examine long run relationship among the series while stationarity properties of the variables was tested by applying structural break test our empirical evidence confirmed long run relationship among the variables the results showed that energy use financial development capital exports imports and international trade have positive impact on economic growth the granger causality analysis revealed that unidirectional causal relationship running from energy use to economic growth financial development and energy use granger cause each other there is bidirectional causality between international trade and energy use the feedback relation exists between financial development and international trade there is also bidirectional causality exists between capital and energy demand financial development and economic growth and international trade and economic growth this paper makes significant contribution in energy economics and opens up new direction for policy makers to explore new and alternative sources of energy which would be helpful in meeting the rising demand of energy due to sustained rate of economic growth

oil and the macroeconomy when prices go up and down an extension of hamilton s results in an important paper hamilton 1983 demonstrated a strong correlation between oil price changes and gross national product growth in u s data however his study pertained to a period in which all the large oil price movements were upward and thus it left unanswered the question whether the correlation persists in periods of price decline moreover the price variable he used was somewhat distorted by price controls in the 1970s this note investigates whether hamilton s results continue to hold when the sample is extended to include the recent oil market collapse and the oil price variable is corrected for the effects of price controls particular attention is given to the possibility of asymmetric responses to oil price increases and decreases as suggested in the structural employment literature loungani 1986 davis 1987 hamilton 1988 like hamilton i based my investigation on the gnp equation in sims s 1 980b six variable quarterly vector autoregressive model

energy efficiency fallacies revisited abstract a number of governments including that of the uk subscribe to the belief that a national program devoted to raising energy efficiency throughout the economy provides a costless indeed profitable route to meeting international environmental obligations this is a seductive policy it constitutes the proverbial free lunch not only avoiding politically unpopular measures like outlawing taxing or rationing offending fuels or expanding non carboniferous sources of energy like nuclear power but doing so with economic benefit the author of this contribution came to doubt the validity of this solution when it was offered as a way of mitigating the effect of the opec price hikes of the 1970 maintaining that economically justified improvement in energy efficiency led to higher levels of energy consumption at the economy wide level than in the absence of any efficiency response more fundamentally he argues that there is no case for preferentially singling out energy from among all the resources available to us for efficiency maximization the least damaging policy is to determine targets enact the restrictive measures needed to curb consumption and then leave it to consumers intermediate and final to reallocate all the resources available to them to best effect subject to the new enacted constraints and any others they might be experiencing there is no reason to suppose that it is right for all the economic adjustment following a new resource constraint to take the form of improvements in the productivity of that resource alone as many others have argued any action to impose resource constraint entails an inevitable economic cost in the shape of a reduction in production and consumption possibilities there would be no free lunch in the last few years debate about the validity of these contentions has blossomed especially under the influence of writers on the western side of the atlantic in this contribution the author outlines the original arguments for questioning whether raised efficiency leads to lower consumption reports more recent developments and offers some insights as food for further thought
