studying the relationship between economic growth co2 emissions and the environmental kuznets curve in venezuela 1980 2025 abstract this work tries to determine whether it is possible to stabilize co2 emissions under a rapid increase of gross domestic product in a medium term the paper is an effort to study in detail how changes in the driving forces of the economy affect co2 emissions we study the case of venezuela for the period 1980 2025 using the methodology proposed by robalino lopez et al 2014 2013 1 2 which is based on an extension of the kaya identity and on a gdp formation approach that includes the effect of renewable energies we test the environmental kuznets curve ekc 3 hypothesis in a coming future under different economic scenarios considering therefore not only past data but also projections for the coming years we use cointegration techniques 4 and the jaunky 2011 5 specification to test the fulfillment of the ekc hypothesis in venezuela our predictions show that venezuela does not fulfill the ekc hypothesis but however the country could be on the way to achieve environmental stabilization in the medium term this stabilization could be accomplished combining economic growth with increasing use of renewable energy appropriated changes in the energy matrix and in the productive sectoral structure

the causality relationship between energy consumption and gdp in g 11 countries revisited abstract this paper explores whether energy conservation policies can be implemented in countries with the same level of development that is is restraining energy consumption without compromising economic growth feasible in all industrialized countries a new granger non causality testing procedure developed by toda and yamamoto 1995 journal of econometrics 66 225 250 is applied to re investigate the relationship if any between energy consumption and income in 11 major industrialized countries the results clearly do not support the view that energy consumption and income are neutral with respect to each other except in the case of the united kingdom germany and sweden where a neutral relationship is found bi directional causality in the united states and uni directional running from energy consumption to gdp in canada belgium the netherlands and switzerland are found this indicates that energy conservation may hinder economic growth in the latter five countries further the causality relationship appears to be uni directional but reversed for france italy and japan which implies that in these three countries energy conservation may be viable without being detrimental to economic growth

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal 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 multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity 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 impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

useful exergy is key in obtaining plausible aggregate production functions and recognizing the role of energy in economic growth portugal 1960 2009 abstract the role of energy in economic growth is controversial models based on aggregate production functions apf range from the neoclassical which downplay energy due to a cost share theorem but typically rely on exogenous total factor productivity tfp to the ecological economic which acknowledge energy s importance the validity of the apf concept itself is questioned here we apply cointegration analysis to identify apfs between output capital labor and possibly energy measured as primary energy or useful exergy we test for tfp growth by including a time trend we require that plausible apfs verify cointegration non negative output elasticities and granger causality linking inputs to output our method recognizes cases where a plausible apfs do not exist thereby addressing the apf critique b energy impacts growth directly c energy impacts growth indirectly through capital and labor we apply the method to portugal 1960 2009 considering standard and quality adjusted capital labor measures with a time trend or disregarding energy plausible apfs are never found without a trend plausible apfs are found only when considering capital energy labor combinations within these with quality adjusted capital and labor and useful exergy results are consistent with the cost share theorem but energy plays a central role through a constraint on all factors of production

energy security and renewable energy deployment in the eu liaisons dangereuses or virtuous circle abstract a large body of literature estimates the effect of energy security drivers on renewable energy deployment using import dependence as a proxy for energy security which is an approach that ignores the potential effect of other energy security strategies such as the diversification of energy sources using panel data for the energy sector across 21 eu member states we investigate the effect of different energy security concepts on the development of renewable energies we compare the results of applying different energy security indicators including the ones used in eu energy policymaking unlike previous studies this study reports a long term relationship between energy security and renewable deployment our findings suggest that the relationship between energy security policies and renewable energy sources res deployment is far from straightforward and depends on the chosen energy security strategy which is usually linked to different energy security conceptualizations our primary findings confirm i that res deployment is a consequence of a combination of energy security strategies including environmental concerns rather than being solely caused by a shift towards more sustainable energy policies and ii that among the different energy security strategies the diversification of energy sources through renewable energy deployment is a more coherent strategy than using res to reduce dependency

energy consumption prices and economic growth in three ssa countries a comparative study in this paper we examine the causal relationship between energy consumption and economic growth in three sub saharan african countries namely south africa kenya and congo drc we incorporate prices as an intermittent variable in a bivariate setting between energy consumption and economic growth thereby creating a simple trivariate framework using the ardl bounds testing procedure we find that the causality between energy consumption and economic growth varies significantly across the countries under study the results show that for south africa and kenya there is a unidirectional causal flow from energy consumption to economic growth however for congo drc it is economic growth that drives energy consumption these findings have important policy implications insofar as energy conservation policies are concerned in the case of congo drc for example the implementation of energy conservation policies may not significantly affect economic growth because the country s economy is not entirely energy dependent however for south africa and kenya there is a need for more energy supply augmentations in order to cope with the long run energy demand in the short run however the two countries should explore more efficient and cost effective sources of energy in order to address the energy dependency problem

cost benefit analysis of reforming israel s electricity industry abstract in june 2003 the israeli government decided to reform the israeli electricity industry which is currently dominated by israel electric corporation iec a government owned vertically integrated electric utility the first step of the planned reform will be taken in 2006 when iec will be functionally separated into generation transmission local distribution and customer services immediately thereafter will be the second step which by 2012 will result in the deregulation and privatization of the wholesale generation and customer services transmission and distribution t and d services will remain regulated but will be available to all t and d users under mandatory open access this paper summarizes a cost benefit analysis of the government s reform plan relative to a regulated regime the government s plan even if carried out flawlessly may only yield a small net benefit however it entails a large increase in electricity producer profit and government tax receipt at the expense of electricity consumers a less than perfect transition to competition can easily wipe out the potential gain of the government plan market reform experience to date shows that electricity market reform can easily fail and the factors for success do not exist in israel since the outcome of a failing reform can be disastrous it will be imprudent to implement the government s plan in 2006 when the current electricity law expires hence we recommend performance based regulation for the period of 2006 2010 subject to an updated cost benefit analysis possible decentralization privatization and competition may follow

estimating technical and allocative efficiency in the public sector a nonparametric analysis of dutch schools abstract public sector output provision is influenced not only by discretionary inputs but also by exogenous environmental factors in this paper we extended the literature by developing a conditional dea estimator of allocative efficiency that allows a decomposition of overall cost efficiency into allocative and technical components while simultaneously controlling for the environment we apply the model to analyze technical and allocative efficiency of dutch secondary schools the results reveal that allocative efficiency represents a significant 37 percent of overall cost efficiency on average although technical inefficiency is still the dominant part furthermore the results show that the impact of environment largely differs between schools and that having a more unfavorable environment is very expensive to schools these results highlight the importance of including environmental variables in both technical and allocative efficiency analysis

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

the relationship among natural gas energy consumption capital and economic growth bootstrap corrected causality tests from g 7 countries abstract this paper examines the relationship between natural gas consumption economic growth and capital by using g 7 countries data and a bootstrap corrected causality test for the period 1970 2008 it was found eight significant granger causality relationships for italy the granger causality is from natural gas consumption to growth and united kingdom adverse for pattern of france germany and united states there is two sided granger causality between natural gas and growth

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 development of renewable energies and supply security a trade off analysis this paper analyzes the effects of the green transformation on the german electricity sector with respect to the energy political triangle it focuses on how the development of renewable energies will affect security of electricity supply in a cost benefit analysis the value of supply security is compared with its costs of provision more specifically the benefits of maintaining the present quality of electricity supply are the avoided social damages from electricity outages and are compared with the respective investment costs in the low and medium voltage distribution grid it is shown that the transformation process towards a green and decentralized production structure will be costly for society even though the costs can be reduced by different measures

reforming israel s electricity sector abstract this paper analyzes the regulatory structure of the electricity sector in israel which is currently dominated by the government owned integrated utility israel electric corporation iec the current structure of a price cap with a mandatory rate reduction of 2 per year and a target return on equity roe of 6 5 is not sustainable because of iec s deteriorating financial health caused by the substantial investments it made to meet the 7 2 per year electricity demand growth in the past decade which has led to an exceptionally low realized roe of 3 4 for that period the investment trend will continue thanks to the 4 5 per year gdp growth projected for the next 10 20 years part of our proposed remedy is performance based regulation pbr implemented via a a price cap formula that will restore iec s financial health and offer iec downward pricing flexibility b changes in how iec compensates its workers and c a sliding scale plan that provides incentives for iec to become more efficient and to share risk with its customers we augment the pbr proposal by recommending changes in iec s tariffs and resource procurement procedures that aim to promote the development of a competitive power industry in the next 10 15 years

environmental kuznets curve and financial development in pakistan abstract in this study we analyzed the effects of financial development per capita real income the square of per capita real income per capita energy consumption and openness on per capita co 2 emissions for pakistan during 1972 2013 the bound f test for cointegration yielded evidence of a long term relationship among these variables the results confirm the existence of an environmental kuznets curve in pakistan for both the short and long term this finding indicates that at the initial stage of development the level of co 2 increases with income and after some threshold level of income this relationship may change from positive to negative as more efficient infrastructure and energy efficient technology are implemented during the development process of the country the findings of this study also reveal a significantly positive sign for the coefficient of financial development suggesting that financial development has occurred at the expense of environmental quality the results further indicate that the key contributing factors to carbon emissions in pakistan are income energy consumption and financial development in addition the openness variable has no significant influence on carbon emission in either the short or long term

causal relationship between energy consumption and gdp growth revisited a dynamic panel data approach abstract this paper uses the panel data of energy consumption and gdp for 82 countries from 1972 to 2002 based on the income levels defined by the world bank the data are divided into four categories low income group lower middle income group upper middle income group and high income group we employ the gmm sys approach for the estimation of the panel var model in each of the four groups afterwards the causal relationship between energy consumption and economic growth is tested and ascertained we discover a in the low income group there exists no causal relationship between energy consumption and economic growth b in the middle income groups lower and upper middle income groups economic growth leads energy consumption positively c in the high income group countries economic growth leads energy consumption negatively after further in depth analysis of energy related data the results indicate that in the high income group there is a great environmental improvement as a result of more efficient energy use and reduction in the release of co2 however in the upper middle income group countries after the energy crisis the energy efficiency declines and the release of co2 rises since there is no evidence indicating that energy consumption leads economic growth in any of the four income groups a stronger energy conservation policy should be pursued in all countries

electricity market reform failures uk norway alberta and california an analysis of electricity market reforms already taken place in the uk norway alberta canada and california usa leads to our overall conclusion that the introduction of a competitive generation market of itself has failed to deliver reliable service at low and stable prices the market reform failures are attributed to market power abuse by few dominant sellers especially at times of transmission congestion poor market design that invites strategic bidding by suppliers the lack of customer response to price spikes capacity shortage caused by demand growth not matched by new capacity and thin trading of forward and futures contracts that are critical for price discovery and risk management the paper then explains why an electricity market reform can easily fail to deliver the promised gains of better service at lower and more stable prices the policy implication is that an electric market reform can be extremely risky and may lead to a disastrous outcome thus it is imprudent to implement such a reform in countries with limited sites for newgeneration and no indigenous fuels e g israel and hong kong these countries should therefore consider introducing performance based regulation that can immediately benefit electricity consumers in terms of lower prices more stable prices improved reliability more choices while encouraging the electric sector to pursue efficient operation and investment r 2003 elsevier science ltd all rights reserved

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

energy consumption economic growth and prices a reassessment using panel vecm for developed and developing countries this paper reinvestigates the energy consumption gdp growth nexus in a panel error correction model using data on 20 net energy importers and exporters from 1971 to 2002 among the energy exporters there was bidirectional causality between economic growth and energy consumption in the developed countries in both the short and long run while in the developing countries energy consumption stimulates growth only in the short run the former result is also found for energy importers and the latter result exists only for the developed countries within this category in addition compared to the developing countries the developed countries elasticity response in terms of economic growth from an increase in energy consumption is larger although its income elasticity is lower and less than unitary lastly the implications for energy policy calling for a more holistic approach are discussed c 2006 elsevier ltd all rights reserved

energy consumption and gdp revisited a panel analysis of developed and developing countries this paper applies a new panel data stationarity testing procedure first developed by carrion i silvestre et al 2005 econometrics journal 8 159 175 with panel vars that employ the generalized method of moment techniques in order to re investigate the dynamic interactions between energy consumption per capita lec and real gdp per capita lry in 22 developed and 18 developing countries when multiple breaks in the series are taken into account there is convincing evidence of panel stationarity for lec and lry in both groups the energy crises evidently had a substantive impact on both lec and lry in all sample countries furthermore our panel vars attest to bidirectional causality between lec and lry in developed countries but there is uni directional causality from lry to lec in developing countries finally from the orthogonalized impulse response functions all of the variables in the panel vars have a positive effect on each other but their impact is greater and more persistent in developing countries some important policy implications do emerge

a critical assessment of the hong kong government s proposed post 2008 regulatory regime for local electricity utilities abstract in december 2005 the hong kong government issued a consultation paper on future development of the electricity markets in hong kong stage ii consultation proposing a post 2008 regulatory regime upon the expiration of the existing regulatory contract between the hong kong government and each of the two local electricity utilities we assess the proposal using the criteria of safe reliable and environmentally friendly service at the lowest rates that will allow the utilities reasonable returns on their investments we caution that if fully adopted the highly risky proposal may lead to less reliable service without the compensating benefits to the environment
