does the energy efficiency paradox exist technological progress and uncertainty we explain why firms may choose not to undertake investments inenergy saving technologies that appear profitable from a net presentvalue perspective as future technological advances are inherentlyuncertain and investments in new technology are at least partly irreversible it may pay to postpone investments in energy savingand wait for the arrival of improved varieties this insight casts doubton the existence of so called low hanging fruits in energy saving although we do not wish to deny that organisational failures may alsobe important failure to appreciate the underlying stochasticity oftechnological progress may obscure the insight that there is value inwaiting and costs involved in terminating the option to invest theappetite for low hanging fruits will be less when these costs areincorporated in the analysis we demonstrate that the effect of thearrival rate of new technologies on the adoption lag for a rational firmis ambiguous the same holds for the effect of the expected jump inefficiency of new technologies government policies aimed at enhancingthe adoption of new technologies through stimulation of r d maytherefore be counterproductive

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

energy consumption and economic growth new insights into the cointegration relationship abstract this paper examines the long run relationship between energy consumption and real gdp including energy prices for 25 oecd countries from 1981 to 2007 the distinction between common factors and idiosyncratic components using principal component analysis allows to distinguish between developments on an international and a national level as drivers of the long run relationship indeed cointegration between the common components of the underlying variables indicates that international developments dominate the long run relationship between energy consumption and real gdp furthermore the results suggest that energy consumption is price inelastic causality tests indicate the presence of a bi directional causal relationship between energy consumption and economic growth

disaggregate energy consumption employment and income in turkey the purpose of this paper is to contribute to literature on energy consumption and economic growth relationship by examining how much of the variance in national income growth can be explained by the growth of different sources of energy consumption and employment in turkey we use the recently developed generalized forecast error variance decomposition technique of koop et al j econom 74 1996 119 and pesaran and shin econ lett 58 1998 17 to determine the information content of the growth rate of energy consumption waste seems to have the largest initial impact followed by oil however over a 3 year horizon lignite appears to explain the largest forecast error variance of gdp the total energy consumption explains 21 of forecast error variance of gdp energy consumption appears to be almost as important as employment in turkey therefore policy makers may be interested in identifying the energy dependencies of economic growth in allocating the energy investment budget

on the causal dynamics between emissions nuclear energy renewable energy and economic growth this paper examines the causal relationship between co2 emissions nuclear energy consumption renewable energy consumption and economic growth for a group of 19 developed and developing countries for the period 1984 2007 using a panel error correction model the long run estimates indicate that there is a statistically significant negative association between nuclear energy consumption and emissions but a statistically significant positive relationship between emissions and renewable energy consumption the results from the panel granger causality tests suggest that in the short run nuclear energy consumption plays an important role in reducing co2 emissions whereas renewable energy consumption does not contribute to reductions in emissions this may be due to the lack of adequate storage technology to overcome intermittent supply problems as a result electricity producers have to rely on emission generating energy sources to meet peak load demand

determinants of long run unemployment this paper investigates the determinants of long run unemployment and growth by extending the endogenous growth model of howitt and aghion 1998 to allow for a more general treatment of the labor market in the spirit of pissarides 1990 we find that i both long run growth and unemployment depend not only on factors that affect long run growth as identified in endogenous growth models with full employment but also on certain labor market parameters ii long run unemployment may rise or fall with growth depending on the model s parameters and iii though government policies that promote growth indirectly through improvement in labor market efficiency always reduce the long run unemployment rate policies that directly encourage investment in research and development may increase the unemployment rate

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

new products quality changes and welfare measures computed from estimated demand systems this paper examines the construction of a price index based on an estimated demand system in principle the method examined can produce a price index that takes account of the introduction of new p

estimating the armington elasticity the importance of study design and publication bias abstract a key parameter in international economics is the elasticity of substitution between domestic and foreign goods also called the armington elasticity yet estimates vary widely we collect 3524 reported estimates of the elasticity construct 32 variables that reflect the context in which researchers obtain their estimates and examine what drives the heterogeneity in the results to account for model uncertainty we employ bayesian and frequentist model averaging to correct for publication bias we use newly developed non linear techniques our main results are threefold first there is publication bias against small and statistically insignificant elasticities second differences in results are best explained by differences in data aggregation frequency size and dimension third the elasticity implied by the literature after accounting for both publication bias and study quality lies in the range 2 5 5 1 with a median of 3 8

small distributed generation versus centralised supply a social cost benefit analysis in the residential and service sectors abstract this paper aims at measuring the social benefits of small chp distributed generation dg in the residential and service sectors we do this by comparing the social costs of decentralised and centralised supplies simulating ideal situations in which any source of allocative inefficiencies is eliminated this comparison focuses on assessing internal and external costs the internal costs are calculated by simulating the optimal prices of the electricity and gas inputs the external costs are estimated by using and elaborating the results of the dissemination process of the externe project one of the most recent and accurate methodologies in this field the analysis takes into account the main sources of uncertainty about the parameter values including uncertainty about external cost estimations despite these sources of uncertainty the paper concludes that centralised supply is still preferable to small dg in fact the overall range of dg social competitiveness is restricted even considering further remarkable improvements in dg electrical efficiency and investment costs the results are particularly unfavourable for the residential sector whereas in the service sector the performance of dg technologies is slightly better

retrospectives on the genius behind david ricardo s 1817 formulation of comparative advantage last year marked the 200th anniversary of ricardo s famous four numbers paragraph on comparative advantage which is one of the oldest analytical results in economics following the lead of james mill 1821 these four numbers have been interpreted as unit labor coefficients this interpretation has provided the basis for the development of the ricardian model from john stuart mill 1852 to eaton and kortum 2002 however if we accept the labor unit interpretation of these numbers ricardo s exposition in his 1817 principles of political economy and taxation makes little logical sense building on sraffa s 1930 interpretation of ricardo s numbers as labor embodied in trade our discussion reveals the amazing simplicity and generality of ricardo s comparative advantage formulation and gains from trade logic

renewable energy consumption and income in emerging economies abstract increased economic growth and demand for energy in emerging economies is creating an opportunity for these countries to increase their usage of renewable energy this paper presents and estimates two empirical models of renewable energy consumption and income for a panel of emerging economies panel cointegration estimates show that increases in real per capita income have a positive and statistically significant impact on per capita renewable energy consumption in the long term a 1 increase in real income per capita increases the consumption of renewable energy per capita in emerging economies by approximately 3 5 long term renewable energy per capita consumption price elasticity estimates are approximately equal to 0 70

renewable and non renewable energy consumption growth nexus evidence from a panel error correction model abstract unlike previous renewable energy consumption growth studies this study examines the relationship between renewable and non renewable energy consumption and economic growth for 80 countries within a multivariate panel framework over the period 1990 2007 the pedroni 1999 2004 heterogeneous panel cointegration test show a long run equilibrium relationship between real gdp renewable energy consumption non renewable energy consumption real gross fixed capital formation and the labor force with the respective coefficient estimates positive and statistically significant there is little difference in the elasticity estimates with respect to renewable and non renewable energy consumption the results from the panel error correction model reveal bidirectional causality between renewable and non renewable energy consumption and economic growth in both the short and long run also there is bidirectional short run causality between renewable and non renewable energy consumption indicative of substitutability between the two energy sources

renewable energy and macroeconomic efficiency of oecd and non oecd economies abstract this article analyzes the effects of renewable energy on the technical efficiency of 45 economies during the 2001 2002 period through data envelopment analysis dea in our dea model labor capital stock and energy consumption are the three inputs and real gdp is the single output increasing the use of renewable energy improves an economy s technical efficiency conversely increasing the input of traditional energy decreases technical efficiency compared to non oecd economies oecd economies have higher technical efficiency and a higher share of geothermal solar tide and wind fuels in renewable energy however non oecd economies have a higher share of renewable energy in their total energy supply than oecd economies

renewable and non renewable energy consumption and economic activities further evidence from oecd countries this article examines the dynamic relationship between renewable and non renewable energy consumption and industrial output and gdp growth in oecd countries using data over the period of 1980 2011 the panel cointegration technique allowing structural breaks is used for empirical investigation the results show that there is a long term equilibrium relationship among non renewable and renewable energy sources industrial output and economic growth the panel causality analyses show bidirectional causality between industrial output and both renewable and non renewable energy consumption in the short and long run however there is evidence of bidirectional short run relationship between gdp growth and non renewable energy consumption while unidirectional causality between gdp growth and renewable energy consumption these results indicate that oecd economies still remain energy dependent for their industrial output as well as overall economic growth however expansion of renewable energy sources is a viable solution for addressing energy security and climate change issues and gradually substituting renewable to non renewable energy sources could enhance a sustainable energy economy

solow meets leontief economic growth and energy consumption abstract this paper proposes a methodology that integrates a growth model with an input output model to analyze the impacts of economic growth on the consumption of energy the integration between the models is carried out by calibrating the growth module which incorporates energetic inputs renewable and nonrenewable in the production function and implementing shocks by the supply side capital labor renewable and nonrenewable energy in the input output model this allows us to verify the pattern of energy consumption for each sector in the input output matrix we apply this methodology to study the energy consumption of eleven economic sectors in brazil using data from the brazilian national accounts and input output matrix ibge and the national energy report ben we conduct experiments involving changes in technological progress growth rate extraction and regeneration rates of both renewable and nonrenewable resources and population growth to analyze the impact of changes in the parameters of the model on the sectoral output growth rate and consequently on the consumption of energy in each economic sector

energy consumption and economic growth evidence from the commonwealth of independent states abstract this study examines the relationship between energy consumption and economic growth for eleven countries of the commonwealth of independent states over the period 1991 2005 within a multivariate panel data framework based on pedroni 1999 pedroni 2004 heterogeneous panel cointegration test and corresponding error correction model cointegration is present between real gdp energy consumption real gross fixed capital formation and labor force with the respective coefficients positive and statistically significant the results of the error correction model reveal the presence of unidirectional causality from energy consumption to economic growth in the short run while bidirectional causality between energy consumption and economic growth in the long run thus the results lend support for the feedback hypothesis associated with the relationship between energy consumption and economic growth

evaluation of financial incentives for combined heat and power chp systems in u s regions abstract in recent years combined heat and power chp systems have gained more attention from the u s government both the federal government and the state government have proposed many incentive policies to promote chp systems this paper focuses on analyzing and evaluating the effectiveness of existing incentive policies for chp systems in various u s states in this paper the existing incentive policies for chp systems in different states are classified in four categories capital cost rebate tax credits low tax loan and utility credits four types of buildings including hospitals large offices large hotels and primary schools located in different u s regions are selected and analyzed for the chp incentives using the energyplus simulation software the energy consumption of each building is obtained then the simulation models of a chp system are established for each building type from the simulation results the payback period of the chp systems in different locations is calculated according to local incentive policies this payback period is then compared with the one without regard for incentive policies the results show that most of the incentive policies could obviously shorten the payback period in various u s regions however some of them seem meaningless because some incentives were not effective enough to give a favorable payback period this paper reveals that the type and level of incentives to promote chp systems need to be carefully determined because the effectiveness and usefulness of incentive policies are highly dependent on the chp performance due to the capacity of the power generation unit the operational strategy of chp system the climate location and the ratio of electricity cost to fuel cost

energy consumption and economic growth nexus for 17 highly developed oecd countries further evidence based on bootstrap corrected causality tests abstract unlike previous energy consumption economic growth studies this study examines the relationship among energy consumption economic growth employment and gross fixed capital formation for 17 highly developed oecd countries by employing both the toda yamamoto procedure which based on asymptotic critical values and the bootstrap corrected causality test since non normality of the error term harms the validity of the toda yamamoto procedure this study finds that there is very small bias due to the assumption of normality furthermore using different information criterions importance of lag length is tested findings indicate that selection of lag length is important for denmark ireland norway and spain it is concluded that while there exists uni directional causality running from energy consumption to real gdp for japan bi directional causality is found for italy new zealand norway and spain on the other hand uni directional causality from gdp to energy is found for australia canada and ireland whereas no causal nexus is found for all of other nine countries our analyses covering the sample periods imply that japan italy new zealand norway and spain should not follow energy conservation policy at the aggregated level since the reduction of energy damages the economic growth

energy consumption and economic growth nexus in portugal italy greece spain and turkey an ardl bounds test approach 1965 2009 abstract the paper examines the nexus between primary energy consumption and growth in portugal italy greece spain and turkey pigst with annual time series data from 1965 to 2009 pigst are southern european economies which have experienced several episodes that make them of particular interest to the study of periods of economic expansion and stagnation an ardl bounds test approach is a suitable technique to examine energy growth nexus within the context of countries with both sporadic shocks outliers and permanent shocks structural breaks empirical results suggest bidirectional causality between energy and growth in both the long run and short run supporting the feedback hypothesis the results reveal themselves to be robust to panel framework an energy conservation policy will reduce gdp growth while a saving phenomenon is observed since one additional unit of product requires less than one unit of energy

the us gains from trade valuation using the demand for foreign factor services about 8 cents out of every dollar spent in the united states is spent on imports what if because of a wall or some other extreme policy intervention imports were to remain on the other side of the us border how much would us consumers be willing to pay to prevent this hypothetical policy change from taking place the answer to this question represents the welfare cost from autarky or equivalently the welfare gains from trade in this article we discuss how to evaluate these gains using the demand for foreign factor services the estimates of gains from trade for the us economy that we review range from 2 to 8 percent of gdp

renewable energy consumption co2 emissions and oil prices in the g7 countries abstract economic and societal issues related to energy security and global warming is placing greater emphasis on the consumption of renewable energy this paper presents and estimates an empirical model of renewable energy consumption for the g7 countries panel cointegration estimates show that in the long term increases in real gdp per capita and co2 per capita are found to be major drivers behind per capita renewable energy consumption these results are robust across two different panel cointegration estimators oil price increases have a smaller although negative impact on renewable energy consumption deviations from equilibrium are driven mostly by the error correction term as opposed to short term shocks short term deviations from the long term equilibrium take anywhere from between 1 3 years france and 7 3 years japan to correct

energy consumption and growth in south america evidence from a panel error correction model abstract this study examines the relationship between energy consumption and economic growth for a panel of nine south american countries over the period 1980 2005 within a multivariate framework given the relatively short span of the time series data a panel cointegration and error correction model is employed to infer the causal relationship pedroni s heterogeneous panel cointegration test reveals a long run equilibrium relationship between real gdp energy consumption the labor force and real gross fixed capital formation with the respective coefficients positive and statistically significant the granger causality results indicate both short run and long run causality from energy consumption to economic growth which supports the growth hypothesis

renewable energy consumption and economic growth evidence from a panel of oecd countries abstract this study examines the relationship between renewable energy consumption and economic growth for a panel of twenty oecd countries over the period 1985 2005 within a multivariate framework given the relatively short span of the time series data a panel cointegration and error correction model is employed to infer the causal relationship the heterogeneous panel cointegration test reveals a long run equilibrium relationship between real gdp renewable energy consumption real gross fixed capital formation and the labor force with the respective coefficients positive and statistically significant the granger causality results indicate bidirectional causality between renewable energy consumption and economic growth in both the short and long run

do combined heat and power plants perform case study of publicly funded projects in new york abstract we investigate lower than expected capacity factors of combined heat and power plants using a publicly available dataset of hourly performance for plants in the state of new york low utilization of a chp indicates underperformance we examine possible causes of this underperformance including economic arbitrage poor maintenance and operational practices oversizing of plants and reliability and resiliency needs based on seasonal and weekday weekend capacity factor averages we find that there is not enough evidence to support the economic arbitrage cause out of 99 plants in the dataset 64 plants have average capacity factor below 60 indicating they are either oversized and or poorly maintained this suggests that the current practice of one time fixed incentive kw favors investment in capacity with no incentive for utilization unlike a production credit which incentivizes generation kw h from a policy perspective this paper recommends better pre engineering assessment for correct sizing as well as revision of incentives based on performance additional information should be collected so that a more accurate ongoing analysis of the societal benefits of chp projects can be made lastly the energy efficiency gap may be smaller than is commonly assumed and other options should be explored to meet energy efficiency goals

energy consumption and gdp in turkey is there a co integration relationship energy consumption and gdp are expected to grow by 5 9 and 7 annually until 2025 in turkey this paper tries to unfold the linkage between energy consumption and gdp by undertaking a co integration analysis for turkey with annual data over the period 1970 2003 the analysis shows that energy consumption and gdp are co integrated this means that there is a possibly bi directional causality relationship between the two we establish that there is a unidirectional causality running from gdp to energy consumption indicating that energy saving would not harm economic growth in turkey in addition we find that energy consumption keeps on growing as long as the economy grows in turkey

renewable energy consumption and growth in eurasia this study examines the causal relationship between renewable energy consumption and economic growth for 13 countries within eurasia over the period 1992 2007 within a multivariate panel data framework the heterogeneous panel cointegration test reveals a long run equilibrium relationship exists between real gdp renewable energy consumption real gross fixed capital formation and labor force the results from the error correction models indicate bidirectional causality between renewable energy consumption and economic growth in both the short run and long run thus the empirical findings lend support for the feedback hypothesis of the interdependent relationship between renewable energy consumption and economic growth

energy consumption income and carbon emissions in the united states abstract this paper investigates the effect of energy consumption and output on carbon emissions in the united states earlier research focused on testing the existence and or shape of an environmental kuznets curve without taking energy consumption into account we investigate the granger causality relationship between income energy consumption and carbon emissions including labor and gross fixed capital formation in the model we find that income does not granger cause carbon emissions in the us in the long run but energy use does hence income growth by itself may not become a solution to environmental problems

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
