energy growth long term relationship under structural breaks evidence from canada 17 latin american economies and the usa abstract we study the relationship and the causal link between electric power consumption epc and gross domestic product gdp both per capita for 17 countries in latin america canada and the usa considering that many of these economies underwent important economic crises in the last three decades we therefore model the epc gdp relationship through a vec specification that allows for structural breaks along with a robust testing methodology of causal links based on the concepts of weak and super exogeneity rather than granger causality evidence favorable to the growth hypothesis epc gdp is found for eight countries while data of three countries support the conservation hypothesis gdp epc for three countries evidence is favorable to the neutrality hypothesis but should be considered with caution as for the remaining five countries the evidence is not conclusive

energy consumption and economic growth nexus in tanzania an ardl bounds testing approach abstract in this paper we examine the intertemporal causal relationship between energy consumption and economic growth in tanzania during the period of 1971 2006 unlike the majority of the previous studies we employ the newly developed autoregressive distributed lag ardl bounds testing approach by pesaran et al 2001 bounds testing approaches to the analysis of level relationships journal of applied econometrics 16 289 326 to examine this linkage we also use two proxies of energy consumption namely total energy consumption per capita and electricity consumption per capita the results of the bounds test show that there is a stable long run relationship between each of the proxies of energy consumption and economic growth the results of the causality test on the other hand show that there is a unidirectional causal flow from total energy consumption to economic growth and a prima facie causal flow from electricity consumption to economic growth overall the study finds that energy consumption spurs economic growth in tanzania

oil price volatility and stock price fluctuations in an emerging market evidence from south korea abstract how important are oil price fluctuations and oil price volatility on equity market performance what are the policy implications if volatility turns out to be significant we assess this issue in an economics finance nexus for korea using a vec model including interest rates economic activity real stock returns real oil prices and oil price volatility our main aim is to capture the effects of crude oil prices on the korean economy thoroughly covering the period of the asian financial crisis of 1997 which heavily affected the country and the oil price hikes in the early 1990s after the gulf war south korea was the country most hit by the financial crisis together with indonesia and thailand results indicate the dominance of oil price volatility on real stock returns and emphasize how this has increased over time oil price volatility can have profound effect on the time horizon of investment and firms need adjust their risk management procedures accordingly this increase in dependency has been found in other net oil importing emerging equity markets we test the relationship between oil price movements and economic activity by using modern time series techniques in a cointegrating framework we expand the standard error correction model by examining the dynamics of out of sample causality through the generalized variance decomposition and impulse response function techniques the evidence from persistence profiles also gives important guidelines based on how fast the entire system adjusts back to equilibrium in addition we find the cointegrating relationship to be stable and find that the linear error correction model to be more favorable than an asymmetric 2 period markov switching model

oil price uncertainty and the canadian economy evidence from a varma garch in mean asymmetric bekk model abstract in this paper we build on recent work by elder and serletis 2010 forthcoming and rahman and serletis forthcoming and investigate the relationship between oil price uncertainty and the level of economic activity using quarterly canadian data over the period from 1974 1 to 2010 1 in doing so we use a bivariate varma garch in mean asymmetric bekk model as detailed in engle and kroner 1995 grier et al 2004 and shields et al 2005 we show that the conditional variance covariance process underlying output growth and the change in the real price of oil exhibits significant non diagonality and asymmetry we also present evidence that increased uncertainty about the change in the real price of oil is associated with a lower average growth rate of real economic activity in canada consistent with the results in elder and serletis 2010 forthcoming and rahman and serletis forthcoming for the united states and elder and serletis 2009 for canada our results are robust to alternative measures of the price of oil alternative measures of the level of economic activity and alternative data frequencies

on electricity consumption and economic growth in china abstract the invention and application of the electric power technology triggered the second industrial revolution in human history which marked the human society entered the age of electricity electricity provides the sustainable power for economic and social development with the rapid development of economy the electricity consumption is also increasing the increase of electricity consumption has further promoted the progress of the industrial economy in order to achieve the goal of improving the level of economic development while reducing energy consumption it is necessary to reveal the relationship between electricity consumption and economic growth this study is an extensive overview of the literature surrounding this topic in this paper we focus on the relationship between electricity consumption and economic growth in china we first analyze the general situation of china s electricity consumption and economic development then we explore the relationship between china s electricity consumption and economic growth from three dimensions i e the time dimension the regional dimension and the industrial dimension finally we study the key issues in the research of the relationship between electricity consumption and economic growth including variable selection model construction and results discussion this work suggests that the nature of the nexus in china should and can be explored from a wider perspective by developing a suitable integrated methodological framework

channel coordination and quantity discounts this paper presents a model for analyzing the impact of joint decision policies on channel coordination in a system consisting of a supplier and a group of homogeneous buyers the joint decision policy characterized by the unit selling price and the order quantity is coordinated through quantity discounts and franchise fees both the annual demand rate and the operating cost including the purchase ordering and inventory holding costs depend on the joint decision policy employed this paper contributes by integrating work addressing quantity discounts on inventory and ordering policies and work focusing on the control mechanism provided by quantity discounts in channel coordination it is shown that the optimal all unit quantity discount policy is equivalent to the optimal incremental quantity discount policy in achieving channel coordination furthermore it is shown that quantity discounts alone are not sufficient to guarantee joint profit maximization the analyses of the general models are illustrated by specific analytical results obtained for a given demand function

a dynamic panel study of economic development and the electricity consumption growth nexus abstract this study examines the relationship between electricity consumption and economic growth for 88 countries categorized into four panels based on the world bank income classification high upper middle lower middle and low income within a multivariate panel framework over the period 1990 2006 the larsson et al 2001 panel cointegration test indicates there is a long run equilibrium relationship between real gdp coal consumption real gross fixed capital formation and the labor force for the high upper middle and lower middle income country panels the results from the panel vector error correction models reveal 1 bidirectional causality between electricity consumption and economic growth in both the short and long run for the high income and upper middle income country panels 2 unidirectional causality from electricity consumption to economic growth in the short run but bidirectional causality in the long run for the lower middle income country panel and 3 unidirectional causality from electricity consumption to economic growth for the low income country panel

the relationship between gdp and electricity consumption in 10 asian countries the purpose of this study is to estimate the relationships between gdp and electricity consumption in 10 newly industrializing and developing asian countries using both single data sets and panel data procedures the empirical results from single data set indicate that the causality directions in the 10 asian countries are mixed while there is a uni directional short run causality running from economic growth to electricity consumption and a bi directional long run causality between electricity consumption and economic growth if the panel data procedure is implemented these empirical findings imply that electricity conservation policies through both rationalizing the electricity supply efficiency improvement to avoid the wastage of electricity and managing demand side to reduce the electricity consumption without affecting the end user benefits could be initiated without adverse effect on economic growth the findings on the long run relationship indicate that a sufficiently large supply of electricity can ensure that a higher level of economic growth

effects of renewable energy sector development on electricity consumption growth nexus in the european union abstract the aim of this study is to assess the effect of renewable energy sector development on the relationships between electricity consumption and economic growth in the european union countries in the period between 1995 and 2015 a panel vector autoregressive model is used for testing granger causality and estimating impulse response functions the results indicate that the relationships between economic growth and electricity consumption depend on the level of renewable energy sector development the greater the share of the renewable energy sector in the economy is the more noticeable the mutual dependence between the economic growth and renewable electricity consumption is in countries with relatively well developed renewable energy sectors renewable electricity consumption boosts the economy and vice versa in the remaining countries economic growth and electricity consumption are independent empirical findings suggest that policymakers should develop strategies to implement clean energy policy aimed at stimulating the development of the renewable energy sector to support economic growth

electricity consumption real gdp causality nexus evidence from a bootstrapped causality test for 30 oecd countries the goal of this paper is to examine any causal effects between electricity consumption and real gdp for 30 oecd countries we use a bootstrapped causality testing approach and unravel evidence in favour of electricity consumption causing real gdp in australia iceland italy the slovak republic the czech republic korea portugal and the uk the implication is that electricity conservation policies will negatively impact real gdp in these countries however for the rest of the 22 countries our findings suggest that electricity conversation policies will not affect real gdp

natural gas consumption and economic growth nexus panel data analysis for gcc countries abstract this study investigates the relationship between natural gas energy consumption and economic growth by including trade openness total labor force and gross fixed capital formation as a major determinants of gdp growth within the multivariate framework model in gulf cooperation council gcc countries a panel gdp model is constructed taking the period of 1980 2012 the result revealed that natural gas energy consumption is cointegrated with gdp growth in the investigated countries in addition based on the panel dynamic ordinary least square dols and the fully modified ordinary least square fmols this study concluded that the natural gas energy consumption affects the gcc s countries gdp growth positively in the long run furthermore the results from the granger causality test revealed bidirectional causality between natural gas energy consumption and gdp growth which confirms the feedback hypothesis from the outcome of this research a number of policy implications were provided for the gcc countries

electricity consumption and economic growth exploring panel specific differences abstract in this paper we examine the long and short run dynamics between electricity consumption and economic activities using panel data of per capita electricity consumption and per capita gdp of 160 countries for the period of 1980 2010 accounting for the degree of electricity dependence and the level of urbanization furthermore in order to capture the differences in this relationship the full sample is divided into various subsamples based on countries income levels regional locations and oecd memberships this framework is argued and found to be appropriate since the causal links and inferences arising therefrom differ considerably among the subsamples which led us to conclude that the electricity growth nexus is highly sensitive to regional differences countries income levels urbanization rates and supply risks

the dynamics of electricity demand in pakistan a panel cointegration analysis abstract this paper examines the dynamics of electricity demand in pakistan at the aggregate and sectoral levels over the period 1978 2012 panel cointegration test and fully modified ordinary least squares method is employed to determine the long run relationship between electricity consumption real income real price of electricity and domestic price of non energy products the results reveal that electricity demand is more responsive to changes in income than changes in prices at the aggregate and disaggregate levels short run and long run income elasticities are positive and statistically significant supporting the conservation hypothesis it appears from the results that long run price elasticities are negative and significant at the aggregate level and for the agriculture commercial residential sectors and public utilities the short run price elasticities are significant but low in magnitude which implies that changes in electricity price exert minimal effect on the electricity consumption in pakistan the domestic price of non energy products is positive and significant for aggregate sample in the short run the domestic price of non energy products exert significant negative positive impact on electricity demand in the agriculture industrial sectors the results thus provide important information to the agents operating in the electricity market regarding the income and pricing policies and helps in planning the future strategy of electricity demand management

estimating the environment kuznets curve hypothesis evidence from latin america and the caribbean countries this study explores the effect of economic growth gdp renewable energy consumption re and financial development fd on co2 emission co2 in latin america and caribbean countries to achieve this goal a panel co2 model was built over the period 1980 2010 the kao cointegration test results revealed that the variables are cointegrated the fully modified ols fmols results indicated an inverted u shape relationship between co2 and gdp thus confirming the environmental kuznets curve hypothesis furthermore fmols results also revealed that fd can improve environmental quality by its negative long run effect on co2 however re has no long run effect on co2 indicating that the re does not contribute to co2 reduction the vecm granger causality results revealed feedback causality between gdp re fd and co2 in both short and long run additionally granger causality results also revealed that re gdp and fd can be a good solution to reduce environmental damage since they have a causal effect on co2 this study shows the investigated countries should increase their banking loans on green energy energy efficiency and energy saving projects to reduce environmental damage in addition the above recommendation can increase the contribution of renewable energy in reducing environmental damage

growth and renewable energy in europe a random effect model with evidence for neutrality hypothesis this is an empirical study on the causal relationship between economic growth and renewable energy for 27 european countries in a multivariate panel framework over the period 1997 2007 using a random effect model and including final energy consumption greenhouse gas emissions and employment as additional independent variables in the model empirical results do not confirm causality between renewable energy consumption and gdp although panel causality tests unfold short run relationships between renewable energy and greenhouse gas emissions and employment the estimated cointegration factor refrains from unity indicating only a weak if any relationship between economic growth and renewable energy consumption in europe suggesting evidence of the neutrality hypothesis which can partly be explained by the uneven and insufficient exploitation of renewable energy sources across europe

oil price shocks and real gdp growth empirical evidence for some oecd countries this study assesses empirically the effects of oil price shocks on the real economic activity of the main industrialized countries multivariate var analysis is carried out using both linear and non linear models the latter category includes three approaches employed in the literature namely the asymmetric scaled and net specifications evidence of a non linear impact of oil prices on real gdp is found in particular oil price increases are found to have an impact on gdp growth of a larger magnitude than that of oil price declines with the latter being statistically insignificant in most cases among oil importing countries oil price increases are found to have a negative impact on economic activity in all cases but japan moreover the effect of oil shocks on gdp growth differs between the two oil exporting countries in the sample with the uk being negatively affected by an oil price increase and norway benefiting from it

the effects of oil price shocks on the iranian economy abstract the iranian economy is highly vulnerable to oil price fluctuations this paper analyzes the dynamic relationship between oil price shocks and major macroeconomic variables in iran by applying a var approach the study points out the asymmetric effects of oil price shocks for instance positive as well as negative oil price shocks significantly increase inflation we find a strong positive relationship between positive oil price changes and industrial output growth unexpectedly we can only identify a marginal impact of oil price fluctuations on real government expenditures furthermore we observe the dutch disease syndrome through significant real effective exchange rate appreciation

macroeconomic performance of oil price shocks outlier evidence from nineteen major oil related countries regions abstract as a special energy commodity oil price shocks can affect not only the energy market but also the performance of the macroeconomy this research provides complementary explanations for nineteen major oil related countries regions macroeconomic effects caused by unexpected oil price changes it focuses on the macroeconomic performance of oil price shocks from outlier perspective investigating the inner hidden factors of co movements between oil price shocks and macroeconomy three methods called empirical covariance ec method robust covariance rc method and one class support vector machine svm method are used in the outlier detection empirical results show that a one class svm method has the best environmental adaptability for detecting the outlier performance of the co movements between oil price shocks and macroeconomy followed by ec and rc methods b according to the time axis the outlier performances of gross domestic production consumer price index and unemployment rate are all concentrated in 2005 2014 which is highly consistent with the oil price shock process and c according to the spatial axis countries four categories with similar outlier performances are obtained outlier performance of macroeconomy of oil related country region in lower levels seems to be worse than that of the country region in higher levels which can be attributed to more attentions paid by higher leveled oil related countries on the oil price shock response system to relieve the severe macroeconomic impacts caused by oil price shocks

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

crude oil and the macroeconomy tests of some popular notions a note perhaps no other economic events in the post world war ii era have generated as much attention as the series of crude oil price shocks that have jolted the world economy since the opec boycott of 1973 a tremendous amount of space in the popular and professional literature has been devoted to analyzing the impacts of these shocks on the developed economies and the adjustments these shocks have induced one residual of this literature has been a general impression that since 1973 the functional relationship between crude oil prices and the developed macroeconomies has been dramatically and fundamentally altered yet to our knowledge no one has formally tested this impression recent evidence of hamilton 1983 suggests that crude oil prices had a strong impact on the u s business cycle well before 1973 further while textbook treatments of oil price shocks tend to highlight cost push inflationary effects the research of berndt and wood 1975 1979 and wilcox 1983 indicates the net complementarity between energy and capital in the u s economy is quite strong both before and after 1973 thus oil price shocks may have stronger real effects than generally believed in this paper we formally test three popular notions associated with the so called

oil price fluctuations and singapore economy this study finds that the impact of an oil price shock on the singapore economy is marginal both impulse response and variance decomposition analysis provide reasonable grounds to believe that the impact only had an insignificant adverse effect on singapore s gross domestic product gdp inflation and unemployment rates further analysis on two oil vulnerability measures supports the finding the declining trend of oil intensity in singapore since 1989 and the declining shares of the singapore s expenditure on oil consumption as a percentage of its nominal gdp this study identifies however that the impact of an oil price shock on the singapore economy should not be considered negligible even though it is small

energy consumption and economic growth revisited in african countries abstract the aim of this paper is to provide new empirical evidence on the relationship between energy consumption and economic growth for 21 african countries over the period from 1970 to 2006 using recently developed panel cointegration and causality tests the countries are divided into two groups net energy importers and net energy exporters it is found that there exists a long run equilibrium relationship between energy consumption real gdp prices labor and capital for each group of countries as well as for the whole set of countries this result is robust to possible cross country dependence and still holds when allowing for multiple endogenous structural breaks which can differ among countries furthermore we find that decreasing energy consumption decreases growth and vice versa and that increasing energy consumption increases growth and vice versa and that this applies for both energy exporters and importers finally there is a marked difference in the cointegration relationship when country groups are considered

electricity consumption and economic growth a time series experience for 17 african countries abstract while the availability of electricity by itself is not a panacea for the economic and social problems facing africa the supply of electricity is nevertheless believed to be a necessary requirement for africa s economic and social development this paper tests the long run and causal relationship between electricity consumption per capita and real gross domestic product gdp per capita for 17 african countries for the period 1971 2001 using a newly developed cointegration test proposed by pesaran et al 2001 and using a modified version of the granger causality test due to toda and yamamoto 1995 the advantage of using these two approaches is that they both avoid the pre testing bias associated with conventional unit root and cointegration tests the empirical evidence shows that there was a long run relationship between electricity consumption per capita and real gdp per capita for only 9 countries and granger causality for only 12 countries for 6 countries there was a positive uni directional causality running from real gdp per capita to electricity consumption per capita an opposite causality for 3 countries and bi directional causality for the remaining 3 countries the result should however be interpreted with care as electricity consumption accounts for less than 4 of total energy consumption in africa and only grid supplied electricity is taken into account

the nexus of electricity consumption economic growth and co2 emissions in the brics countries abstract this study reexamines the causal link between electricity consumption economic growth and co 2 emissions in the brics countries i e brazil russia india china and south africa for the period 1990 2010 using panel causality analysis accounting for dependency and heterogeneity across countries regarding the electricity gdp nexus the empirical results support evidence on the feedback hypothesis for russia and the conservation hypothesis for south africa however a neutrality hypothesis holds for brazil india and china indicating neither electricity consumption nor economic growth is sensitive to each other in these three countries regarding the gdp co 2 emissions nexus a feedback hypothesis for russia a one way granger causality running from gdp to co 2 emissions in south africa and reverse relationship from co 2 emissions to gdp in brazil is found there is no evidence of granger causality between gdp and co 2 emissions in india and china furthermore electricity consumption is found to granger cause co 2 emissions in india while there is no granger causality between electricity consumption and co 2 emissions in brazil russia china and south africa therefore the differing results for the brics countries imply that policies cannot be uniformly implemented as they will have different effects in each of the brics countries under study

energy demand and stock market development in oecd countries a panel data analysis abstract this paper investigates the impact of stock market developments on oil and electricity demand of oecd member countries we conduct different panel data methodologies and use annual data ranging from 1996 to 2011 the overall findings substantiate that income real prices size of the stock market and liquidity are important determinants for both oil and electricity demand we also compute long run elasticity coefficients by using a simple partial adjustment model pam and find that the long run elasticity coefficients are larger than the short run parameters moreover our results show that the demand for oil and electricity is inelastic with respect to both own real price and real income over the short run and the long run from a policy making perspective the findings suggest that potential policy tools to reduce energy consumption may not be useful as the demand for energy is inelastic with respect to energy prices our results also manifest that although stock market deepening variables do not have a large effect on energy use as energy price and economic growth have market size and liquidity significantly affect energy consumption therefore energy demand estimations based on solely energy price and income may be inaccurate when some stock market development indicators are excluded the empirical findings of this paper provide further insights for policy makers energy companies and energy economists in terms of demand management policies and pricing decisions

oil prices and news based uncertainty novel evidence abstract in this paper using news implied volatility nvix as a key variable to measure news based uncertainty we investigate whether the world price of oil and three classical oil shocks affect news based uncertainty or vice versa our analysis is conducted through the news mechanism that is unrelated to fundamentals this research contributes to the literature on the effect of oil prices on news based uncertainty by studying the dynamics in both the time and frequency domains using the wavelet coherence analysis our results illustrate that oil prices exhibit a statistically and economically significant leading role on nvix especially in the long run further we distinguish the different impacts of oil shocks and find that the oil supply and aggregate demand shocks usually play a leading role on relatively long term nvix while the oil specific demand shocks are sensitive to the fluctuations of nvix we also find that the rules of comovement between oil prices oil shocks and news based uncertainty change at different frequencies and times they usually move together in opposite directions with the exception of the oil supply shocks and nvix these findings apply to both oil spot and futures markets our results present new and interesting implications for investors and policy makers by supporting the news reallocation channel as an important transmission mechanism from oil markets

are energy conservation policies effective without harming economic growth in the gulf cooperation council countries abstract this study explores the fossil fuels electricity consumption growth of the gross domestic product gdp relationship in the six gulf cooperation council gcc countries for the period 1980 2012 the aim of this study is to examine whether energy conservation policies are appropriate for these countries to reduce their high levels of electricity consumption the autoregressive distributed lag ardl and the toda yamamoto dolado lutkepohl tydl methodologies were employed to investigate this relationship the ardl results revealed that fossil fuels electricity consumption has a long run positive effect on gdp growth in the gcc countries however the tydl granger causality revealed different causality relationships among the countries a bi directional causality was found between fossil fuels electricity consumption and gdp growth in bahrain and the united arab emirates uae while one way causality from fossil fuels electricity consumption to gdp growth was found in oman and qatar on the other hand no causality was concluded between the variables in kuwait and saudi arabia from the results it is clear that energy conservation is not an ideal policy for the bahrain uae oman and qatar because it will have a negative consequence on their output however this policy can be implemented in kuwait and saudi arabia since it will not harm their output

the electricity consumption versus economic growth of the polish economy abstract the aim of this contribution is an investigation of causal interdependences between electricity consumption and gdp in poland our research was conducted for total electricity consumption as well as for the industrial consumption of electricity in order to reflect the causality between gdp and electricity consumption properly we performed our investigations in a three dimensional framework with employment chosen as an additional variable we used reliable quarterly data from the period q1 2000 q4 2009 in order to check the stability of the causalities the investigations were performed on two samples a full sample and a pre crisis i e q1 2000 q3 2008 subsample we applied both traditional methods and some recently developed econometric tools we found feedback between total electricity consumption and gdp as well as between total electricity consumption and employment we also found unidirectional causality running from industrial electricity consumption to employment and no direct causal links between industrial electricity consumption and gdp in addition all these findings were in general not seriously affected by the financial and economic crises of 2008 a significant exception is the causal effect of industrial electricity consumption on employment which was more pronounced after the crisis of 2008

identifying the oil price macroeconomy relationship an empirical mode decomposition analysis of us data this paper employs the empirical mode decomposition emd method to filter cyclical components of us quarterly gross domestic product gdp and quarterly average oil price west texas intermediate wti the method is adaptive and applicable to non linear and non stationary data a correlation analysis of the resulting components is performed and examined for insights into the relationship between oil and the economy several components of this relationship are identified however the principal one is that the medium run component of the oil price has a negative relationship with the main cyclical component of the gdp in addition weak correlations suggesting a lagging demand driven component and a long run component of the relationship were also identified comparisons of these findings with significant oil supply disruption and recession dates were supportive the study identifies a number of lessons applicable to recent oil market events including the eventuality of persistent oil price and economic decline following a long oil price run up in addition it was found that oil market related exogenous events are associated with short to medium run price implications regardless of whether they lead to actual supply losses

electricity consumption and economic growth in china cointegration and co feature analysis abstract this paper applies the cointegration theory to examine the causal relationship between electricity consumption and real gdp gross demostic product for china during 1978 2004 our estimation results indicate that real gdp and electricity consumption for china are cointegrated and there is only unidirectional granger causality running from electricity consumption to real gdp but not the vice versa then hodrick prescott hp filter is applied to decompose the trend and fluctuation component of the gdp and electricity consumption series the estimation results indicate that there is cointegration between not only the trend components but also the cyclical components of the two series which implies that the granger causality is probably related with the business cycle the estimation results are of policy implication to the development of electric sector in china

relationships between oil price shocks and stock market an empirical analysis from china this paper investigates the interactive relationships between oil price shocks and chinese stock market using multivariate vector auto regression oil price shocks do not show statistically significant impact on the real stock returns of most chinese stock market indices except for manufacturing index and some oil companies some important oil price shocks depress oil company stock prices increase in oil volatility may increase the speculations in mining index and petrochemicals index which raise their stock returns both the world oil price shocks and china oil price shocks can explain much more than interest rates for manufacturing index

renewable and non renewable electricity consumption environmental degradation and economic development evidence from mediterranean countries abstract in this article we develop an empirical model to investigate the causal link amid renewable and non renewable electricity consumption gdp and carbon emissions by using a panel of 9 mediterranean countries over the period 1980 2014 using the pmg panel ardl and panel econometric technics heterogeneity and cross sectional dependence among the panel were considered to explore the long and short run dynamic relationships as well as the validity of a proposed model the results provide panel empirical evidence that there is short term bidirectional causality between gdp renewable electricity consumption and co2 emissions and between non renewable electricity consumption gdp and renewable electricity consumption for the long term causal relationship the result indicates that there is bidirectional causality between non renewable electricity consumption and co2 emissions however there is evidence of unidirectional causal relationships from gdp to co2 emissions and non renewable electricity consumption and from renewable electricity consumption to co2 emissions the findings imply that non renewable electricity consumption and economic growth stimulate co2 emissions in southern and northern mediterranean countries while renewable electricity reduces them this empirical evidence suggests that expansion of renewable energy sources is a viable strategy for addressing energy security and reducing carbon emissions to protect the environment for future generations

the effect of renewable and nonrenewable electricity generation on economic growth abstract this note examines the impact of electricity generation on economic growth using data for a panel of 174 countries over the period 1980 2012 the paper makes several contributions first contrary to much of the literature the paper focuses on the effect of electricity generation on economic growth because of transmission and distribution losses and theft not all the electricity that is generated is eventually consumed making it necessary to investigate the impact of electricity generation on growth second we disentangle the impact of total electricity generation on growth into renewable and nonrenewable effects with increasing pursuit of energy security technological advances the falling costs of renewables and the movement to exploit renewable energy sources for electrification there is need to study not only the impact of traditional sources of electricity but renewable sources as well third we deviate from previous studies that focus on granger causality and or cointegration by estimating the effect of electricity generation on growth using the system generalized method of moments gmm given that electricity generation and many of the other regressors in our model may be jointly determined with gdp growth the system gmm approach is appropriate to deal with these endogeneity issues fourth we provide evidence of a link between electricity loss and economic growth our results indicate a strong positive and statistically significant relationship between renewable and nonrenewable electricity generation and growth

nonlinear causality between crude oil price and exchange rate a comparative study of china and india while several studies have examined the linear causal relationship between oil prices and exchange rates little is known about the nonlinear causality between these two variables the present paper tries to fill this research gap in the context of india and china by applying the hiemstra and jones 1994 nonlinear granger causality test to the var residuals the study finds a significant bi directional nonlinear granger causality between oil prices and exchange rates in both countries the findings suggest that the nonlinearity of oil price influences the exchange rate irrespective of the exchange rate regimes further to check robustness the persistence in the variance of oil price and exchange rate is taken into account using a garch 1 1 model while the results consistently hold in the case of india with respect to china a unidirectional causality runs from exchange rate to oil price however the oil price in china does not granger cause exchange rate

liquidity surprise volume and return premia in the oil market abstract we investigate oil market price dynamics in the context of the mixture of distributions hypothesis mdh our econometric model addresses autoregressive properties in returns the impact of surprise volume and conditional oil market return volatility as well as oil market liquidity in the conditional return equation surprise volume as a proxy of private information flow is shown to be unrelated to a set of standard market liquidity proxies oil return heteroscedasticity is found to be partly explained by surprise volume a finding that is consistent with the mdh our findings further show that both oil market liquidity as well as surprise volume shocks are priced in the oil market as such lower levels of lagged market liquidity relate to above average conditional returns surprise volume shocks are associated with lower conditional oil market returns jointly with higher contemporaneous conditional return volatility lagged market liquidity dominates conditional volatility in predicting conditional oil price returns

are oil shocks inflationary asymmetric and nonlinear specifications versus changes in regime this paper identifies a structural break in core u s inflation phillips curves such that oil prices contributed substantially before 1981 but since that time pass through has been negligible this characterization is robust to a variety of re specifications and fits the data better than asymmetric and nonlinear oil price alternatives evidence does not support the hypotheses that declining energy intensity or deregulation of energy producing and consuming industries played an important role monetary policy did not itself become less accommodative of oil shocks but may have helped create a regime where inflation is less sensitive to price shocks more generally

oil prices and the impact of the financial crisis of 2007 2009 abstract oil prices increased dramatically during 2004 2006 industry experts initially attributed these price increases to fundamental factors such as the rise in global demand but also because of disruptions in the supply of oil the price increases however were so substantial that additional factors are needed to explain such dramatic changes we propose that the decline in the value of the u s dollar measured both by the appreciation of the euro and of gold prices played an important role as oil suppliers demanded compensation for the declining value of the dollar using a markov switching regime methodology we find evidence that this hypothesis is true prior to the financial crisis but its validity does not hold after the crisis when oil prices crashed and the dollar rallied

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

electricity consumption growth nexus evidence from panel data for transition countries abstract this paper investigates the long run relationship and causality issues between electricity consumption and economic growth in 15 transition countries albania belarus bulgaria czech republic estonia latvia lithuania macedonia moldova poland romania russian federation serbia slovak republic and ukraine by using the pedroni panel cointegration method for the 1990 2006 period results suggest that the pedroni panel cointegration tests do not confirm a long term equilibrium relationship between electricity consumption per capita and real gdp per capita moreover since no cointegration was found error correction mechanisms plus causality tests cannot be run for further steps in the long term to investigate the causality between electricity consumption and economic growth overall it can be said that the electricity consumption related policies have no effect or relation on the level of real output in the long run for these countries as a conclusion the literature has conflicting results and there is no consensus either on the existence or the direction of causality between electricity consumption and economic growth thus the findings of this study have important policy implications and it shows that this issue still deserves further attention in future research

98 effective integer ratio lot sizing for one warehouse multi retailer systems a warehouse supplies n retailers constant external demand occurs at each retailer and shortages are not allowed there are linear holding costs and fixed costs for ordering at the warehouse and at each retailer the goal is to minimize the long run average cost over an infinite time horizon we define a new class of policies for this problem whose simple structure facilitates both computation and implementation the cost of a policy that is optimal within this class is shown to be within 2 of the cost of an optimal policy for the original problem in the worst case such a policy can be computed in on log n time

dynamic jumps in global oil price and its impacts on china s bulk commodities abstract this paper investigated the impacts of oil price shocks especially dynamic jumps in its returns on china s bulk commodity markets at both the aggregate and industry levels after setting a zero lower bound to the jump intensity of the arji model we found that dynamic jumps exist in oil price movements moreover under shocks of oil price jumps not only the returns but also the risks of china s bulk commodity markets are affected significantly and the reactions of risks are characterized by overreactions meanwhile by decomposing oil price shocks into expected positive negative and unexpected positive negative components we discovered that the impacts of unexpected shocks are positive and significantly asymmetric at both levels while those of the expected shocks are negative and insignificantly asymmetric at the industry level in addition the volatility clustering of all price movements and the permanent volatility effects on china s bulk commodities are also authenticated by applying the garch family models

an operational policy for a three stage distributive supply chain system with retailers backorders abstract this research deals with a production inventory problem consisting of three stage tree type single producer multi distributor and multi retailer supply chain network where a model has been developed for achieving the lowest total cost for operating a supply chain system with allowable shortage in this research the shortage is assumed to occur in a form of backorder the refrigerator manufacturing can suitably be used to illustrate the scenario which makes the situation more rational and realistic by assumptions the customers will not go somewhere else the cost of lost sale is not included in this case the total cost of this tree type distributive supply chain system is comprised of setup costs and holding costs at all echelons and the backorder cost at retailer level only a replenishment policy is sought to operate the system at a minimum cost the problem is formulated as an unconstrained mixed integer programming problem and a newly developed doubly hybrid meta heuristic algorithm is adopted as the solution procedure the solutions which determine the desired replenishment policy for the producer distributors and retailers are obtained to minimize the total system cost a sensitivity analysis is performed to evaluate the outcome of the proposed solution procedure presented in this research numerical results are generated to demonstrate the solution procedure and future research is indicated for further study

price of oil and world inflation and recession new evidence shows that the commonly held assumption that the 1973 74 oil price increase directly affected us and world inflation and subsequent recession is consistent with the empirical data an extended lucas varro real income equation applied to the us united kingdom canada france germany italy japan and the netherlands gives mixed results partly because of price control and decontrol programs simulation experiments on the price control variable using us data finds strong effects further studies can be made when consistent international data is available for the 1979 80 period 18 references 4 figures 3 tables dck

estimation of electricity demand function for algeria revisit of time series analysis abstract this paper aims to empirically re examine whether economic growth has effect on electricity consumption for algerian economy we have incorporated urbanization and trade openness in electricity demand function as additional determinants of electricity consumption for the period of 1971 2012 for empirical purpose we have applied the recently developed combined cointegration test proposed by bayer and hanck 2013 and bounds testing approach to cointegration by pesaran et al 2001 for establishing the cointegration between the variables by accommodating structural breaks the results expose that income growth leads to higher electricity demand along with urbanization being another major contributing factor of rising electricity demand in contrast trade openness leads to reduce electricity demand the causal association between the variables is further examined with the application of innovation accounting approach of vector autoregressive var the empirical evidence indicates the presence of the neutral effect between income growth and electricity use urbanization causes electricity use and electricity use causes urbanization in granger sense

electricity consumption in g7 countries a panel cointegration analysis of residential demand elasticities this article applies recently developed panel unit root and panel cointegration techniques to estimate the long run and short run income and price elasticities for residential demand for electricity in g7 countries the panel results indicate that in the long run residential demand for electricity is price elastic and income inelastic the study concludes that from an environmental perspective there is potential to use pricing policies in the g7 countries to curtail residential electricity demand and thus curb carbon emissions in the long run

energy consumption and gdp causality a three step analysis for emerging european countries abstract the established european targets should play a leading role in the complex economic process of energy consumption and the emerging countries have to consider their implications for adjusting the energy policies at national level this paper develops investigations on the causality relationship between energy consumption and gdp in the context of emerging european countries covering the period 1980 2013 this research covers the limits identified by previous researchers by detailing the energy consumption by sources and by referring to five emerging countries in europe unlike most of the previous studies it has a double approach long and short run bidirectional relationships a detailed analysis on the impact of economic growth on the energy consumption by country is conducted in order to contribute to the enrichment of the research field towards this objective a three step analysis is performed stationarity cointegration and causality tests are considered the empirical study shows mixed results there is a balance in confirming conservation growth and neutrality hypotheses in some specific cases results imply that energy consumption and economic growth are jointly determined however a comparative analysis for different significance levels draws attention on the differences in judgment of results for this type of studies discussions on the results in terms of causality are conducted in order to identify future trends for research

what happened to the oil price macroeconomy relationship abstract strong evidence is found that oil prices no longer granger cause many u s macroeconomic indicator variables in data after 1973 a number of potential explanations are explored that sample stability issues are responsible that oil prices are now endogenous and that linear and symmetric specifications misrepresent the form of the oil price interaction none of these hypotheses are supported by the data the opec price increases do appear to have had significant impacts while the effects of the price declines of the 1980s are smaller and harder to characterize these results have potentially important implications for the large body of research which utilizes oil prices as an instrumental or explanatory variable

cointegration and causality between electricity consumption and gdp empirical evidence from malawi abstract the granger causality gc and error correction ecm techniques were applied on 1970 1999 data for malawi to examine cointegration and causality between electricity consumption kwh and respectively overall gdp agricultural gdp agdp and non agricultural gdp ngdp cointegration was established between kwh and respectively gdp and ngdp but not with agdp the gc results detect bi directional causality between kwh and gdp suggesting that kwh and gdp are jointly determined but one way causality running from ngdp to kwh the ecm results detect causality running one way from gdp also from ngdp to kwh suggesting that a permanent rise in gdp may cause a permanent growth in electricity consumption

the causal relationship between electricity consumption and economic growth in the asean countries abstract this paper investigates the causal relationship between electricity consumption and economic growth among the association of south east asian nations asean 4 members namely indonesia malaysia singapore and thailand using modern time series techniques for the period 1971 2002 the results indicate that there is a bi directional causality between electricity consumption and economic growth in malaysia and singapore this means that an increase in electricity consumption directly affects economic growth and that economic growth also stimulates further electricity consumption in the two countries however uni directional causality runs from economic growth to electricity consumption in indonesia and thailand without any feedback effect thus electricity conservation policies can be initiated without deteriorating economic side effects in the two countries

electricity consumption and economic growth bounds and causality analyses of opec members this paper investigates the relationship between electricity consumption and economic growth for opec members the bounds test yields evidence of a long run relationship between electricity consumption and economic growth for all opec members causality results suggest that economic growth is dependent on electricity consumption in five countries less dependent in three countries and independent in three countries because these countries do not necessarily share similar political and economic traits no single universal policy implication can be inferred from the results the disparities across these causality results therefore stress the importance of formulating causality explanations while taking into account the particularities of individual countries rather than blindly applying the conventional interpretations

oil and the macroeconomy since the 1970s economists have long been intrigued by empirical evidence that suggests that oil price shocks may be closely related to macroeconomic performance this interest dates back to the 1970s the 1970s were a period of growing dependence on imported oil unprecedented disruptions in the global oil market and poor macroeconomic performance in the united states thus it was natural to suspect a causal relationship from oil prices to u s macroeconomic aggregates since then a large body of work has accumulated that purports to establish this link on theoretical grounds and to provide empirical evidence in its support we do not attempt a comprehensive survey of this literature but rather provide an idiosyncratic synthesis of what we view as the key issues in this debate and the insights gained over the last 30 years the timing seems right for such an account although the experience of the 1970s continues to play an important role in discussions of the link between oil and the macroeconomy there have been a number of new oil price shocks since the 1970s notably the 1986 collapse of oil prices and the 2000 boom in oil prices as well as the oil price increases associated with the 1990 1991 gulf war and the 2003 iraq war given this richer case history we are arguably in a better position than two decades ago to distinguish the idiosyncratic features of each oil crisis from the systematic effects increases in oil prices have been held responsible for recessions periods of excessive inflation reduced productivity and lower economic growth in this paper we review the arguments supporting such views first we highlight some of the conceptual difficulties in assigning a central role to oil price shocks in explaining

oil price movements and macroeconomic performance evidence from twenty six oecd countries abstract this study investigates the relationship between oil price movements and macroeconomic aggregates such as gross domestic product gdp consumer prices cpi and unemployment for oecd countries to do this second generation econometric methods have been employed to panel data including panel unit root tests panel cointegration tests and panel long run models panel unit root tests suggest that oil prices plus selected macroeconomic aggregates in oecd countries are non stationary at levels but become stationary at first differences in the existence of multiple structural breaks five structural break points have successfully been investigated in the series of this study during panel unit root and panel cointegration tests durbin h panel co integration tests confirm that there is a long term relationship between oil prices and those macroeconomic aggregates on the other hand results of this study reveal that the price of oil exerts statistically and negatively significant impacts on gdp cpi and unemployment in the case of oecd countries in general

this is what happened to the oil price macroeconomy relationship abstract many of the quarterly oil price increases observed since 1985 are corrections to even bigger oil price decreases the previous quarter when one looks at the net increase in oil prices over the year recent data are consistent with the historical correlation between oil shocks and recessions

electricity consumption and economic growth in transition countries a revisit using bootstrap panel granger causality analysis abstract the purpose of this paper is to revisit the granger causal relationship between electricity consumption and economic growth for 15 transition economies for the period 1975 2010 using a bootstrap panel causality approach that allows for both cross sectional dependency and for heterogeneity across countries applying this approach we found a unidirectional causality running from electricity consumption to economic growth only in belarus and bulgaria from economic growth to electricity consumption in the czech republic latvia lithuania and the russian federation bidirectional causality only in ukraine while no granger causality in any direction in albania macedonia moldova poland romania serbia slovak republic and slovenia these results show that there is a limited support for the electricity led growth hypothesis nevertheless these different findings provide important implications for energy strategies and policies for transition countries

reverse globalization does high oil price volatility discourage international trade this paper examines whether higher oil price volatility causes a reversal in globalization using a large annual panel data set covering 84 countries all over the world from 1984 to 2008 we investigate the impacts of oil price fluctuations on international trade namely exports and imports we present strong and robust evidence that international trade flows will be lower when oil prices fluctuate significantly we therefore conclude that oil price volatility hurts globalization

the impact of oil price shocks in the canadian economy a structural investigation on an oil exporting economy abstract oil price shocks and monetary policy response by oil producing economies have been the subject of important theoretical investigation in the modern literature this topic seems to be well grounded since fluctuations in the us dollar which is affected by us monetary policy plays an important role in exacerbating run ups and precipitous falls in world oil prices we investigate the economic consequences of oil price shocks using an open economy dsge model that incorporates demand for and supply of oil while allowing for interaction between domestic and foreign monetary policy using canadian and u s data we quantify the relative importance of oil price shocks and monetary policy response on macroeconomic variables we show that domestic monetary policy is a key channel that accounts for over 40 of discounted variation in domestic output across a 4 year horizon after an oil shock in contrast us monetary policy is of lesser importance in propagating oil price shocks on an oil exporting economy through the international channel

the optimal and heuristic solutions of a distribution network abstract competitive environment of global networking and customization call for cost reduction in arborescent tree like inventory system one of the keys to cost reduction is the integration of the supply chain much practical research has been done in the area of integrating the inventory system in recent years integration involves the joint decision making among the producer the distributors and the retailers in the supply chain by revising goyal s model an optimal solution is derived in this paper a heuristic solution model is also developed for a producer distributors retailers inventory system using the principle of strategic partnership numerical results indicate the heuristic solution is a good estimation of the optimal solution

the joint economic lot size problem a review abstract this article reviews lot size models which focus on coordinated inventory replenishment decisions between buyer and vendor and their impact on the performance of the supply chain these so called joint economic lot size jels models determine order production and shipment quantities from the perspective of the supply chain with the objective of minimizing total system costs this paper first describes the problem studied introduces the methodology of the review and presents a descriptive analysis of the selected papers subsequently papers are categorized and analyzed with respect to their contribution to the coordination of different echelons in the supply chain finally the review highlights gaps in the existing literature and suggests interesting areas for future research

relationship between oil prices interest rate and unemployment evidence from an emerging market abstract while the interrelation between oil price changes economic activity and employment is an important issue that has been studied mainly for developed countries little attention has been devoted to inquiries on fluctuations in the price of crude oil and its impact on employment for small open economies adopting an efficiency wage model for equilibrium employment that does not require any assumptions regarding labor supply this paper contributes to the literature by investigating the causality between unemployment and two input prices namely energy crude oil and capital real interest rate in an emerging market turkey for the period 2005 01 2009 08 applying a relatively new technique the toda yamamoto procedure we find that the real price of oil and interest rate improve the forecasts of unemployment in the long run this finding supports the hypothesis that labor is a substitute factor of production for capital and energy

economic growth and electricity consumption in former soviet republics abstract this study estimates the causal relationship between electricity consumption and economic growth with annual data for the commonwealth independent states countries in three groups of income levels empirical results reveal that electricity consumption and gdp are cointegrated for all these countries furthermore there is a unidirectional causality from electricity consumption to gdp for all groups in the long run effect of electricity consumption on the gdp is negative for the second group of countries which supports the energy conservation policies whereas it is positive for the first and third group of countries which supports the growth hypothesis

the role of portuguese electricity generation regimes and industrial production abstract this paper examines how renewables special regime simultaneously interact with conventional sources ordinary regime within the portuguese electricity generation system there is also an appraisal of the relationship between these two regimes and economic activity using the industrial production index first difference var modelling was applied for monthly data for the time span of 2007 m1 to 2012 m10 the appropriateness of the var is proved the relationship between variables develops within a structure of endogeneity i e they generate feedback and may be both explained and explaining variables simultaneously the outcomes show a strong complementarity between the ordinary and special regimes economic activity causes electricity consumption but only the special regime causes economic activity moreover the non renewable component of the special regime does not cause a need for backup from either the ordinary regime or imports contributing to a reduction in energy dependency

economic welfare impacts from renewable energy consumption the china experience over the last years renewable energy sources have increased their share on electricity generation of china due to environmental and security of supply concerns in this work author assesses the role of both the amount and share of renewable energy consumption in economic welfare using cobb douglas type production functions this assessment is carried out by multivariate ols and spss software for china from 1978 to 2008 results indicate that a 1 increase in renewable energy consumption rec increases real gdp by 0 120 gdp per capita by 0 162 per capita annual income of rural households by 0 444 and per capita annual income of urban households by 0 368 respectively the impact of renewable energy consumption share srec on economic welfare is insignificant and an increasing share of rec negatively affects economic welfare growth to a certain extent in this paper the cost structural demand accounting mechanism and policy reasons of renewable energy development are interpreted marginal effects analysis show that the shape of sound and robust renewable energy institutions and policies would matter for increasing the standards of economic welfare in the context of speeding up renewable energy development and increasing share of renewable energy consumption especially the goal oriented policy refinement should be addressed efficiently in improvement households income while increasing share of renewable energy consumption c 2011 elsevier ltd all rights reserved

the electricity consumption and gdp nexus for the fiji islands fiji is a small open island economy dependent on energy for its growth and development hence the relationship between energy consumption and economic growth is crucial for fiji s development in this paper we investigate the nexus between electricity consumption and economic growth for fiji within a multivariate framework through including the labour force variable we use the bounds testing approach to cointegration and find that electricity consumption gdp and labour force are only cointegrated when gdp is the endogenous variable we use the granger causality f test and find that in the long run causality runs from electricity consumption and labour force to gdp implying that fiji is an energy dependent country and thus energy conservation policies will have an adverse effect on fiji s economic growth

the link between renewable energy production and gross domestic product in africa a comparative study between 1980 and 2008 abstract renewable energy re projects are arguably one of the most important strategies that can be used in the mitigation of climate change impacts at the same time re technologies can generate clean energy and potentially boost the economy of the african continent it is thus not surprising that recent studies have investigated the relationship between re and economic growth in some african countries however the limitation of these reductionist analytical frameworks is that they can conceal the true regional picture in terms of the link between investments in re technologies and gross domestic product gdp this holistic analysis is important in order to inform regional policies on climate change the article uses statistical analytic techniques to examine the correlation between re production and economic growth across different blocks of the african continent between 1980 and 2008 the analysis is between geographical blocks e g southern africa western africa etc and between oil and non oil producing blocks generally speaking while there exists a similar pattern in all the studied blocks in terms of mean standard deviation and correlation between re and gdp a few exceptions can be found for instance the rise in re gdp correlation from 1992 1993 onwards was conspicuously higher in north africa and oil producing countries compared to all the other blocks similarly southern africa was the only block where the correlation between re and gdp was negative throughout the period under review except 1988 1989 and 1997 when it was positive

a literature survey on energy growth nexus abstract this paper provides a survey of the recent progress in the literature of energy consumption economic growth and electricity consumption economic growth causality nexus the survey highlights that most empirical studies focus on either testing the role of energy electricity in stimulating economic growth or examining the direction of causality between these two variables although the positive role of energy on growth has become a stylized fact there are some methodological reservations about the results from these empirical studies a general observation from these studies is that the literature produced conflicting results and there is no consensus neither on the existence nor on the direction of causality between energy consumption electricity consumption and economic growth as a policy implication to avoid from conflicting and unreliable results the authors may use the autoregressive distributed lags bounds test two regime threshold co integration models panel data approach and multivariate models including new variables such as real gross fixed capital formation labor force carbon dioxide emissions population exchange rates interest rates etc thus the authors should focus more on the new approaches and perspectives rather than by employing usual methods based on a set of common variables for different countries and different intervals of time

relationship between energy production and water resource utilization a panel data analysis of 31 provinces in china abstract the systematic study of the relationship between energy production and water resource utilization is crucial for china to relieve the energy water crisis and achieve sustainable use of them this work explores the causal relationship between energy production and water resource utilization in china using panel data of 31 provinces over the period 2000 2014 this study have applied a panel unit root test cointegration test vector error correction model vecm and granger causality approaches to examine the long run and short run relationship between the variables the results show that 1 there is a long run bidirectional granger causality relationship between energy production and water resources utilization but a short run unidirectional relationship between two variables i e the water resource utilization is the short run granger reason for the change in energy production 2 the increases in industrial added value population and ratio of the secondary industry value added to gdp have a positive effect on both energy production and water resource utilization 3 industrial water use will fall by about 0 12 if the rate of industrial waste water reuse increases by 1 which shows that the progress of water saving technology can reduce industrial water usage effectively our findings indicate that government should implement strict water constraint strategies and promote water conservation technology for the sustainable development of energy and water resources in china

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

demand customer base line and demand response in the electricity market a survey the increasing use of demand side management as a tool to reliably meet electricity demands at peak time has stimulated interest among researchers consumers and producer organiza tions managers regulators and policymakers this research reviews the growing literature on models which are used to study demand customer base line cbl and demand response in the electricity market after characterizing the general demand models the cbl based on which the demand response models are studied is reviewed given the experience gained from the review and existing conditions the study combines an appropriate model for each case for a possible application to the electricity market moreover it discusses the implications of the results in the literature these aspects are studied independently the main contribution of this survey is attributed to the treatment of the three issues as sequentially interdependent the review is expected to enhance the understanding of the demand cbl and demand response in the electricity market and their relationships the objective is conducted through a combination of demand and supply side managements in order to reduce demand through different demand response programs during peak times this enables electricity suppliers to save costly electricity generation and at the same time reduce energy vulnerability
