the impact of the german feed in tariff scheme on innovation evidence based on patent filings in renewable energy technologies abstract over the last two decades feed in tariffs have pushed the massive expansion of electricity from renewable energy sources in germany between 1991 and 1999 feed in tariffs were prescribed through the electricity feed in law the so called stromeinspeisungsgesetz seg at relatively moderate rates from 2000 onwards the seg was replaced by the renewable energy sources act the so called erneuerbare energien gesetz eeg with much higher subsidy rates the rise in subsidies to renewable power generation under the eeg came along with a substantial increase in electricity prices provoking an intense public debate on the benefits of renewable energy promotion in our regression analysis we assess one popular justification for feed in tariffs the demand side effect of induced innovation we find that the innovation impact of the german feed in tariff scheme over the last two decades supports the positive innovation hypothesis however the inducement effect of the feed in tariff scheme under the eeg is not significantly different from that of the seg given the drastic cost of the eeg we caution against the appraisal of the eeg feed in tariff scheme solely on the grounds of its impact on technological innovation

public policy supports and export performance of bioenergy technologies a dynamic panel approach abstract this study investigates the effects of public policy supports on the export performance of bioenergy technologies it uses panel data from 18 countries from the 1992 to 2008 period panel unit root and cointegration tests are applied taking into account the results of structural break tests for each time series and testing for the presence in the panel of cross sectional dependence time series data on public supports and exports are integrated and cointegrated the results of dynamic ordinary least squares indicate that in the long term public r d expenditures have a positive effect on the exports the contribution of bioenergy to the total energy supply has a negative effect on the exports and gdp has a positive effect on the exports the contribution of bioenergy to total energy supply responds to deviations in the previous period from the long term equilibrium additionally blundell bond system generalized methods of moments estimations are made to determine dynamic causality in a panel vector error correction mechanism setting evidence of a positive strong and short term relationship from exports to r d expenditures and of a positive short term causality from exports to the contribution of bioenergy to total energy supply is found a positive strong bidirectional relationship between gdp and exports is also uncovered there is a positive strong bidirectional and short term relationship between gdp and the contribution of bioenergy to total energy supply finally some policy implications based on the results of this study are offered

does s kuznets s belief question the environmental kuznets curves this paper examines the link between pollution and income the main purpose is to assess whether the introduction of income inequality in a environmental kuznets curve ekc analysis can give new insights into the relationship between pollution and economic growth the ekc hypothesis proposes that there is an inverted u shape relation between environmental degradation and income per capita we question this common result in a simple model where the income inequality evolution is exogenous and where the planner could use only one instrument for a set of parameter values we find for example a two hump curve jel classification d3 h4 q2 est ce que le postulat de s kuznets remet en question les courbes environnementales a la kuznets cet article analyse la relation entre pollution et revenu l objectif de cet article est de montrer comment la prise en compte de l inegalite des revenus dans une analyse de la courbe environnementale de kuznets peut modifier la relation entre pollution et croissance l hypothese de la courbe environnementale de kuznets revient a supposer l existence d une forme en u inverse entre la degradation de l environnement et le revenu par tete cet article remet en cause ce resultat a l aide d un modele simple dans lequel l inegalite du revenu evolue de maniere exogene et ou le planificateur ne peut utiliser qu un seul instrument pour certaines valeurs des parametres du modele nous trouvons que la relation entre la pollution et le revenu suit une courbe a deux bosses

interrelationships between income health and the environment extending the environmental kuznets curve hypothesis abstract this paper examines the link between the health indicators and the environmental variables for a cross section of countries widely dispersed on the economic development spectrum while environment and income are seen to have an inverted u shaped relationship environmental kuznets curve ekc hypothesis it is also well established that environment and health are positively related our study focuses on the implications of this for the relationship between health and income in the early phases of income growth the gains in health and the losses in environmental quality could cancel each other out and this challenges the idea that as incomes increase health would always improve to empirically analyse these issues we estimate a two stage least squares model that focuses on the impact of income and the environment on health status with environment being an endogenous variable our results show that the environmental stress variable has a significant negative effect on health status at the same time gross national product gnp levels are shown to vary positively with health status variables we find that the health gains obtained through improved incomes can be negated to a significant extent if the indirect effect of income acting via the environment is ignored research findings in this regard would be a useful policy instrument towards maximising both the environmental and health gains that come with economic growth and development

on the nexus of financial development economic growth and energy consumption in china new perspective from a gmm panel var approach abstract this paper studies the endogenous relationships among financial development energy consumption and economic growth in china by applying a gmm panel var approach with a panel data of 30 chinese provinces over the period 1996q1 2015q4 financial development is measured by six individual indicators and by a comprehensive indicator obtained through the pca method we also account for regional heterogeneity by dividing our sample into three regions eastern region central region and western region we underline our findings in three aspects first financial development measured by most individual indicators m2 credit revenue of the insurance industry and stock market value and the comprehensive one has a significantly negative impact on economic growth second energy consumption can significantly contribute to economic growth in all regions while no feedback effect is found except in the western region this result is further supported by the granger causality tests last financial development in the sense of m2 credit stock turnover and the comprehensive indicator can significantly lessen energy consumption in all regions but this inhibitory effect is found to be largest in the western region followed by the eastern region and be smallest in the central region the granger causality tests confirm further the existence of heterogeneity across regions a bidirectional granger causality between the two variables is found in the eastern region a unidirectional granger causality running from energy consumption to financial development is identified in the central region and no significant causal relationship shows up in the western region our findings provide valuable policy implications for china heading for a green economic growth

energy consumption and energy r d in oecd perspectives from oil prices and economic growth abstract we estimate the short run and long run elasticities of various types of energy consumption and energy r d to changes in oil prices and income of the 20 oecd countries over the period of 1980 2010 using the nerlove partial adjustment model npam we find negative income elasticity for coal consumption but positive income elasticity for oil and gas consumption suggesting the importance of economic growth in encouraging the usage of cleaner energy from coal to oil and gas by introducing time dummies into the regressions we show that climatic mitigation policies are able to promote the usage of cleaner energies through the dynamic linkages between energy consumption and energy r d we find that fossil fuel consumption promotes fossil fuel r d and fossil fuel r d in turn drives its own consumption renewable energy r d which is more responsive to economic growth reduces fossil fuel consumption and hence fossil fuel r d

testing the environmental kuznets curve hypothesis across the u s evidence from panel mean group estimators abstract it is widely believed that greenhouse gases contribute to a warmer climate since global warming is a serious threat and greenhouse gas emissions are one of the main causes of it analyzing the effects of economic development on environment have great importance in this study the validity of the environmental kuznets curve ekc hypothesis is tested for the 50 u s states during the 1960 2010 period using recent panel data estimators that take cross sectional dependence and slope heterogeneity into account accordingly the cross sectional dependence and slope heterogeneity robust estimators augmented mean group amg and common correlated effects mean group estimator ccemg provide mixed results the amg estimator strongly validates the ekc hypothesis asserting that the ekc holds in 30 of the 50 states with turning points for income per capita lie between 1292 and 48597 on the contrary the ccemg estimator provides only weak evidence on the ekc hypothesis and the ekc holds only in 10 states with turning points between 2457 and 14603

the effects of environmental regulation and technical progress on co2 kuznets curve an evidence from china based on environmental kuznets curve theory a panel data model which takes environmental regulation and technical progress as its moderating factors was developed to analyse the institutional and technical factors that affect the path of low carbon economic development the results indicated that there was a co2 emission kuznets curve seen in china environmental regulation had a significant moderating effect on the curve and the inflection of co2 emissions could come substantially earlier under stricter environmental regulation meanwhile the impact of technical progress on the low carbon economic development path had a longer hysteresis effect but restrained co2 emission during its increasing stage and accelerated its downward trend during the decreasing stage which was conducive to emission reduction strict environmental regulation could force the high carbon emitting industries to transfer from the eastern regions to the central or the western regions of china which would make the co2 kuznets curve higher in its increasing stage and lower in its decreasing stage than that under looser regulation furthermore energy efficiency energy structure and industrial structure exerted a significant direct impact on co2 emissions we should consider the above factors as essential in the quest for low carbon economic development

regional heterogeneity of china s energy efficiency in new normal a meta frontier super sbm analysis abstract this study aims at investigating regional heterogeneity of china s energy efficiency in the new normal a model combining meta frontier method and super sbm is proposed which has higher discriminatory power under the group frontier the energy efficiencies of the eastern central western and northeastern china and each provinces were estimated during 2006 2016 we also discussed the technology gaps of different regions the changes in energy efficiency and the main influencing factors of energy efficiency the results show that the highest energy efficiency lied in eastern china surprisingly the technology levels of central and western china have improved rapidly furthermore as china enters a new normal period more regions showed a strong decoupling relationship between energy consumption and economic growth meanwhile the regression results indicate that both state intervention and market openness had negative impacts on energy efficiency in different study periods finally according to the local conditions of different regions several policy recommendations to promote china s regional energy efficiency improvement are proposed

inequality as a cause of environmental degradation abstract this paper advances two hypotheses first the extent of an environmentally degrading economic activity is a function of the balance of power between the winners who derive net benefits from the activity and the losers who bear net costs second greater inequalities of power and wealth lead all else equal to more environmental degradation

effects of policies on patenting in wind power technologies abstract this paper explores the effects of policies and other factors driving innovation in wind power technologies in twelve oecd countries over more than two decades patent counts are used as an indicator for innovation the factors considered are generally derived from the systems of innovation literature count data econometric model were used for the estimations the suggest that patenting in wind power technology is positively related to public r d in wind power reflecting supply side policy the stock of wind capacity reflecting learning effects the number of patents per capita reflecting a country s innovative capacity and the share of green party voters reflecting the legitimacy of the technology in particular the presence of production or capacity targets for wind power or renewable energy sources and a stable policy environment reflecting policy process appear to be favourable for patenting wind power technologies these results are robust to various model specifications distributional assumptions and alternative classifications of wind power technologies in the patent search

the impacts of removing energy subsidies on economy wide rebound effects in china an input output analysis abstract facing with the increasing contradiction of economic growth energy scarcity and environmental deterioration energy conservation and emissions abatement have been ambitious targets for the chinese government improving energy efficiency through technological advancement is a primary measure to achieve these targets however the existence of energy rebound effects may completely or partially offset energy savings associated with technological advancement this paper adopted a modified input output model to estimate the economy wide energy rebound effects across china s economic sectors with the consideration of energy subsidies the empirical results show that the aggregate rebound effect of china is about 1 9 in 2007 2010 thus technological advancement significantly restrains energy consumption increasing removing energy subsidies will cause the aggregate rebound effect declines to 1 53 specifically removing subsidies for coal and nature gas can reduce the rebound effects signifcantly while removing the subsidies for oil products has a small impact on rebound effect the existence of rebound effects implies that technological advancement should be cooperated with energy price reform so as to achieve the energy saving target in addition the government should consider the diversity of economic sectors and energy types when design the reform schedule

china s energy demand and its characteristics in the industrialization and urbanization process a reply zhang and qin 2013 argued that in jiang and lin 2012 the equation form and variable selection should be altered and it was problematic to use regression equation to project the future in this reply we disagree with and will refute some of the points raised in their comments the model that we established was based on the mature economic theory with the variable selections all having economic implications considering the economic development stage china s urbanization will speed up and this will have significant effect on energy consumption therefore urbanization is an indispensable variable for analyzing energy demand in china the scenario design only in terms of the gdp is sufficient for illustrating energy demand trend in china to be understood in a way by most of the people although energy forecast is not that precise it has an important implication for energy policy design especially for china which is in transition and china s energy demand will keep high growth in the mid term

the environmental kuznets curve ekc theory part b critical issues according to the environmental kuznets curve ekc theory the process of economic growth is expected to limit the environmental degradation created in the early stages of development the first article of this study reviews the empirical studies examining various factors other than income that may lead to an ekc pattern the current article reviews in the first part the major critiques on the ekc speculation which relate to the following issues the normal distribution of world income the feedback from environmental degradation to economic growth the characteristics of the pollutant in question various econometric issues the evolution of consumption when income rises and the assumption about a common developmental pattern in all countries the second part discusses additional matters reported indirectly in the literature and or must be further examined there are doubts whether the gdp series captures the transition of production to the three productive sectors in empirical estimations and whether services are less polluting compared to industry activities finally the original kuznets theory which laid the groundwork for the ekc concept does not seem to solve income inequality problems

green innovation transformation economic sustainability and energy consumption during china s new normal stage abstract as china s economy is transforming into a new normal stage the energy industry is becoming increasingly innovation driven which is shown particularly in renewable energy given that the green innovation transformation is crucially critical during china s new normal stage this paper analyzes the direct impact of energy consumption on energy innovation and innovation transformation and reveals the net effect of green innovation transformation on economic sustainability and energy consumption micro and macro empirical evidence are both provided in this paper by implementing two estimation methodologies fixed effect model and generalized method of moments gmm vector autoregression var approach respectively estimating chinese micro 153 listed energy companies data and macro 30 provincial data from 2009 to 2016 we find that 1 in terms of energy enterprises innovation activity behavior energy consumption could promote total energy innovation of which renewable energy innovation is stimulated far more significantly 2 there is an increasing tendency for energy structure to transform into renewables as the energy consumption increases 3 the green innovation transformation instead of total innovation counts can reduce energy consumption and benefit economic sustainability therefore the structure of innovation transformation plays more significant role than total energy innovation in stimulating economic growth and alleviating the energy consumption antinomy during china s new normal stage in this regard in order to stimulate green energy transformation government should implement financing policy reduce administrative intervention upgrade energy legal system and improve energy pricing mechanism to encourage more research and development r d activities at the core of renewable energy

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

north south negotiations on emission reductions a bargaining approach this article models north south negotiations on emission reductions where the north provides side payments in exchange for the south s adoption of a more stringent emission standard we find that depending on where firms compete strong asymmetry among regions the two regions different valuations of side payments and climate change damage can produce self enforcing cooperative agreements moreover the south s optimal standard choice can be one of two polar cases i e either the cleanest or the dirtiest irrespective of the continuum of standards available the results above can also hold true when both parties bargain over the south s emission tax

corruption pollution and the kuznets environment curve abstract this paper examines the implications of corruption and rent seeking behavior by the government for the relationship between pollution and growth cases of both cooperative and non cooperative interaction between the government and the private firm are studied it is shown that corruption is not likely to preclude the existence of an inverted u shaped kuznets environmental curve under both these cases however for any level of per capita income the pollution levels corresponding to corrupt behavior are always above the socially optimal level further the turning point of the kuznets curve takes place at income and pollution levels above those corresponding to the social optimum

economic growth and the transition from traditional to modern energy in sweden we examine the role of substitution from traditional to modern energy carriers and of differential rates of innovation in the use of each of these in economic growth in sweden from 1850 to 1950 we use a simple growth model with a nested ces production function and exogenous factor augmenting technological change and carry out a counterfactual simulation based on the econometric results even though the rate of technical change was higher for modern energy innovation in the use of traditional energy carriers contributed more to growth between 1850 and 1890 since the cost share of traditional energy was so much larger than that of modern energy in that period however after 1890 we find that modern energy contributed much more to economic growth than traditional energy but increasingly labor augmenting technological change became the most important single driver of growth

impact of energy technology patents in china evidence from a panel cointegration and error correction model abstract enhancing energy technology innovation performance which is widely measured by energy technology patents through energy technology research and development r d activities is a fundamental way to implement energy conservation and emission abatement this study analyzes the effects of r d investment activities economic growth and energy price on energy technology patents in 30 provinces of china over the period 1999 2013 several unit root tests indicate that all the above variables are generated by panel unit root processes and a panel cointegration model is confirmed among the variables in order to ensure the consistency of the estimators the fully modified ols fmols method is adopted and the results indicate that r d investment activities and economic growth have positive effects on energy technology patents while energy price has a negative effect however the panel error correction models indicate that the cointegration relationship helps to promote economic growth but it reduces r d investment and energy price in the short term therefore market oriented measures including financial support and technical transformation policies for the development of low carbon energy technologies an effective energy price mechanism especially the targeted fossil fuel subsidies and their die away mode are vital in promoting china s energy technology innovation

rich enough to go renewable but too early to leave fossil energy abstract typically environmental kuznets curve ekc studies on energy concentrate on the emissions produced from energy production or consumption and neglect the aspect of exhaustion of a natural resource which is an irreversible result against any definition of sustainability and intergenerational equity this paper investigates whether there is an environmental kuznets curve for renewable energy whether there should be one and if there is what it should stand for for this reason the paper employs balanced panel data for 33 european member and candidate state countries that produce crude oil natural gas coal and renewable energy for the years 1990 2010 to investigate the relationship between their scale of economic activity fossil energy production and the production of renewable energy results from random effects models together with arellano bond estimator models identify the u shape for the environmental kuznets curve only for renewable energy and coal production a theoretical justification on the mechanisms possibly driving the environmental kuznets curve for renewable energy are also discussed
