innovation in the energy sector lessons learnt from r d expenditures and patents in selected iea countries abstract long time series of the iea and international patent offices offer a huge potential for scientific investigations of the energy innovation process thus this paper deals with a broad literature review on innovation drivers and barriers and an analysis of the knowledge induced by public research and development expenditures r d and patents in the energy sector the cumulative knowledge stock induced by public r d expenditures in 14 investigated iea countries is 102 3 bn eur in 2013 nuclear energy has the largest share of 43 9 bn eur followed by energy efficiency accounting for 14 9 bn eur fossil fuels with 13 5 bn eur and renewable energy with 12 1 bn eur a regression analysis indicates a linear relation between the gdp and the cumulative knowledge with each billion eur of gdp leading to an additional knowledge of 3 1 mil eur however linearity is not given for single energy technologies further the results show that appropriate public r d funding for research and development associated with a subsequent promotion of the market diffusion of a niche technology may lead to a breakthrough of the respective technology

assessing income population and technology impacts on co2 emissions in canada where s the ekc abstract this study investigates the macroeconomic forces underlying carbon dioxide co2 emissions from fossil fuel use in canada in keeping with the relevant literature on environmental degradation three forces are expected to influence co2 emissions gross domestic product per capita gdp capita population and technological change while previous work has employed reduced form models that allow for non linear relationships between co2 and gdp capita it has been common practice to assume linear relationships between co2 and the latter two variables this study tests a more flexible model using a five region panel data set in canada over the period 1970 2000 findings indicate that gdp capita is unrelated to co2 that an inverted u shaped relationship exists with population and that a u shaped relationship exists with technology thus technological and population changes are supported over the commonly hypothesized environmental kuznets curve an inverted u shaped relationship between gdp capita and environmental degradation for affecting co2 emissions from fossil fuel use in canada

industrial pollution in economic development the environmental kuznets curve revisited abstract using new international data this paper tests the environmental kuznets curve ekc hypothesis for industrial water pollution we measure the effect of income growth on three determinants of pollution the share of industry in national output the share of polluting sectors in industrial output and end of pipe eop pollution intensities per unit of output in the polluting sectors we find that the industry share of national output follows a kuznets type trajectory but the other two determinants do not when combined our results imply rejection of the ekc hypothesis for industrial water pollution it rises rapidly through middle income status and remains roughly constant thereafter

baumol s disease and dematerialization of the economy this paper argues that there is reason to be skeptical about the idea that the transition to a service economy will bring about dematerialization of production and consequent environmental improvement this is because the shift to a service economy is an illusion in terms of real production but is instead generated by the fall in the price of manufacturing goods relative to services which is in turn caused by more rapid productivity growth in manufacturing than in services this argument relies on the insights baumol provided on the nature of the service economy and uses swedish long term data on relative sectoral development as an empirical illustration on the other hand the paper argues that there is reason to be cautiously optimistic that structural change may bring about a greening of growth namely the changes in growth patterns sometimes labeled the third industrial revolution which is connected to the emergence of microelectronics swedish co2 emissions show a decline after 1970 which is mainly explained by a politically driven change in the mix of energy carriers but is also related to the stabilization of energy consumption this energy stabilization was caused by slow growth of the economy in conjunction with substantial declines in energy intensity within industrial sectors and an absence of relative growth of the heavy sectors a growth that had marked the economy between 1870 and 1970 microelectronics have contributed to permanently transforming the swedish industrial sector in a lighter direction reducing energy losses in heavy industries and stabilizing household energy consumption so it appears as if there may be some environmental gains from this development that was initiated in the 1970s but not from relatively more production in the service sector

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 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

environmental innovation and environmental performance abstract by estimating a simultaneous panel data model of environmental innovation and toxic air pollution this paper identifies bi directional causal links between the two we study a panel of 127 manufacturing industries over the period 1989 2004 pollutant emissions are an implicit measure of policy stringency and environmental patent counts are used to measure environmental innovation after accounting for the joint endogeneity we find that environmental innovation is an important driver of reductions in us toxic emissions conversely we find that tightened pollution targets induce environmental innovation however our estimates indicate that the environmental policy multiplier the proportionate contribution of induced innovation to long run emission reduction is small

determinants of co2 emissions in a small open economy abstract the aim of the paper is to explore the relationship between economic development and carbon dioxide co2 emissions for a small open and industrialized country austria we test whether an environmental kuznets curve relationship also holds for a single country rather than concentrating on panel or cross section data for a set of countries a cubic i e n shaped relationship between gdp and co2 emissions is found to fit the data most appropriately for the period 1960 1999 and a structural break is identified in the mid seventies due to the oil price shock furthermore two variables are additionally significant import shares reflecting the well known pollution haven hypothesis and the share of the tertiary service sector of total production gdp accounting for structural changes in the economy emission projections derived from this single country specification support the widely held opinion that significant policy changes are asked for when implementing the kyoto protocol in order to bring about a downturn in future carbon emissions

an alternative analysis of apparent ekc type transitions abstract the hypothesis of the environmental kuznets curve ekc depends upon the assumption that countries pass through a similar environmental impact trajectory as they experience income growth implying that income levels determine pollution levels the authors present evidence that this is not representative of the way many individual country s pollution emission trajectories evolve and question the emphasis on income determinism by the ekc the study proposes that nonlinear dynamic systems analysis provides a more complete description of individual country pollution trajectories in the case of co 2 emissions the nonlinear time trajectories show abrupt transitions that occur contemporaneously with historical events and over a broad range of incomes

inequality of energy intensities across oecd countries a note abstract this paper proposes the use of theil s second measure to analyze international energy intensity differences this index allows differences to be broken down within and between groups of countries in a consistent manner an analysis of oecd countries for the period 1971 1999 shows some basic points first the fall in energy intensities differences is attributable both to within group and between group inequality components second between group inequalities are currently the main contributor to the whole inequality value finally a detailed exploration on within group inequalities reveals the significant explanatory role played by eu countries

strategic choices for renewable energy investment conceptual framework and opportunities for further research this paper introduces the special issue on strategic choices for renewable energy investment which is a collection of best papers presented at an international research conference held in st gallen switzerland in february 2010 substantial private investment is needed if public policy objectives to increase the share of renewable energy and prevent dangerous anthropogenic climate change are to be achieved the aim of this paper and the entire special issue is to draw scholarly attention to the processes underlying strategic choices for renewable energy investment and how they are influenced by energy policy we disentangle the role of risk return perceptions portfolio effects and path dependence in explaining energy investment decisions and suggest that the heterogeneous universe of investors requires a segmentation of policies the paper outlines some of the rich opportunities for further research in this emerging area

energy innovations ghg emissions nexus fresh empirical evidence from oecd countries abstract this study explores the impact of improvements in energy research development erd on greenhouse gas ghg emissions using environmental kuznets curve hypothesis for 28 oecd countries over the period of 1990 2014 in doing so we have employed a panel data where public budget in energy research development and demonstration erd d has transformed into a finite inverted v lag distribution model developed by de leeuw 1962 this model considers that energy innovation accumulates in time and presents empirical evidence how energy innovation contributes in reducing energy intensity and environmental pollution as well our results indicate that energy innovation measures require lapses of time to reach their full effect i e innovation applied to measures for environmental correction does not reach its whole effect immediately requiring instead a certain amount of time to pass innovation policies have recommended for improving environmental quality

are there limits to growth a simple theoretical model of pollution is developed that generates an inverted u shape relationship between per capita income and environmental quality this model is then used to study long run growth the same inverted u shape is shown to appear in time series and the prospects for sustained growth are shown to hinge on whether increasingly strict environmental regulation is compatible with a constant rate of return on capital implementation is also studied tax and voucher schemes are shown to have an advantage over direct regulation because they provide the correct incentives for capital accumulation copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

global estimates of energy consumption and greenhouse gas emissions abstract the present study examines the long run relationship between energy consumption and greenhouse gas emission for different groups of countries comprising lower middle income upper middle income and heavily indebted countries east asia and pacific east europe and central asia latin america and caribbean middle east and north africa south asia sub saharan africa and for aggregate data of the world the data has been analyzed by using various econometric techniques specifically the johnson cointegration modified version of granger causality and variance decomposition analysis from the period of 1975 to 2011 the results confirm that there is a long run relationship between greenhouse gas emissions i e agricultural methane emission agricultural nitrous oxide emission and carbon dioxide emission and energy consumption the results of granger causality indicate that energy consumption granger causes greenhouse gas emission but not vice versa the important finding is that energy consumption granger causes gdp per unit energy use which confirms the energy led growth hypothesis in the world however the vice versa relationship does not hold the results imply that a policy to cut energy consumption tends to diminish greenhouse gas emission though affecting gdp of countries negatively

do urbanization and industrialization affect energy intensity in developing countries abstract against a backdrop of concerns about climate change peak oil and energy security issues reducing energy intensity is often advocated as a way to at least partially mitigate these impacts this study uses recently developed heterogeneous panel regression techniques like mean group estimators and common correlated effects estimators to model the impact that income urbanization and industrialization has on energy intensity for a panel of 76 developing countries in the long run a 1 increase in income reduces energy intensity by 0 45 to 0 35 long run industrialization elasticities are in the range 0 07 to 0 12 the impact of urbanization on energy intensity is mixed in specifications where the estimated coefficient on urbanization is statistically significant it is slightly larger than unity the implications of these results for energy policy are discussed

air quality and economic growth an empirical study abstract in the present empirical study we have observed an inverse and sometimes u shaped relationship between environmental degradation and per capita real income as opposed to the inverted u shaped environmental kuznets curve ekc found in many earlier studies it was felt that a possible explanation of the observed pattern of relationship might be sought in the dynamics of the process of economic growth experienced by the countries concerned thus e g economic development may strengthen the market mechanism as a result of which the economy may gradually shift from non market to marketed energy resources that are less polluting this phenomenon may show up in the form of an inverse relationship as mentioned above also due to the global technical progress the production techniques available to the countries all over the world are becoming more and more capital intensive and at the same time less polluting this may mean that given the income level the pollution level decreases as the capital intensity of an economy rises in the present study it is indeed observed that as capital intensity increases the level of suspended particulate matter spm in the atmosphere decreases per capita real income is also found to be inversely related to spm partially but the interaction effect of per capita income and capital intensity on spm is observed to be positive this suggests that given the level of per capita income capital intensity a more capital intensive production technique a higher per capita income level would cause less pollution for spm a surprising result is also obtained i e a u turn is observed at a very high level of per capita real income i e us 12 500 at 1985 us prices this is possibly indicative of the fact that there are technological limits to industrial pollution control such that beyond a threshold level of income further rise in income cannot be achieved without environmental degradation

quantitative modelling of the eur chf exchange rate during the target zone regime of september 2011 to january 2015 krugman 1991 s target zone model for exchange rate dynamics has become the reference of a large part of this literature despite its simplicity and elegance empirical evidence has been lacking not least because it is difficult to capture the predicted non linear relationship between the observable exchange rate and the non observable fundamental value this is why we propose a different approach by inverting locally the relation between exchange rate and fundamental value we derive analytical expressions for the conditional volatility and the probability density as a function of the exchange rate this allows us to examine krugman s prediction directly from historical data and furthermore enables us to test the smooth pasting condition which is intimately related to the no arbitrage condition concretely we study the performance of the euro swiss franc exchange rate in the extraordinary period from september 6 2011 to january 15 2015 when the swiss national bank enforced a minimum exchange rate of 1 20 swiss francs per euro we show that the data are well explained by the theory and conclude that krugman s target zone model holds after all but apparently only under extreme and sustained pressure that pushes continuously the exchange rate very close to the boundary of the target zone

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
