global energy use decoupling or convergence we examine the key factors driving change in energy use globally over the past four decades we test for both strong decoupling where economic growth has less effect on energy use as income increases and weak decoupling where energy use declines overtime in richer countries ceteris paribus our econometric approach is robust to the presence of unit roots unobserved time effects and spatial effects our key findings are that the growth of per capita energy use has been primarily driven by economic growth convergence in energy intensity and weak decoupling there is no sign of strong decoupling

performance diversity and national identity evidence from association football the increasing national diversity of coworkers has no consensus on its impact on performance using a team s predominant nationality as a proxy for national diversity and national identity there is robust evidence that it affects team and individual performance detailed worker level data from a highly globalized industry association football show a nonlinear relationship between performance and the predominant nationality of a team s roster as the number of members from the predominant nationality increases performance declines however beyond a threshold level performance rises it follows that performance benefits from national diversity when the predominant nationality is small and from national identity when it is large jel m14 z21 z22 j15

why haven t global markets reduced inequality in emerging economies the theory of comparative advantage predicts that globalization should cause inequality in emerging economies to fall however this has not been true of the current globalization even though the prediction held up well for previous such episodes in this paper i sketch an alternative theory developed in collaboration with michael kremer that seems to fit recent history well

convergence in per capita energy use among oecd countries abstract unlike previous studies which mainly focus on the integration properties of energy consumption and production this study examines the convergence of per capita energy use among 25 oecd countries over the period 1960 to 2010 in particular newly developed lm and rals lm unit root tests with allowance for two endogenously determined structural breaks are employed the results indicate significant support for per capita energy use convergence among oecd countries

eu renewable energy support policy faith or facts the recent eu commission proposal for promoting the supply of power from renewable energy sources was originally based on a pan european harmonised tradable green certificate tgc scheme we suggest on the basis of a multi disciplinary analysis that a pan eu tgc system is not the way forward for europe it is vital that the commission and the majority of member states avoids implementation of such policy designs put forward by a coalition of vested interests they should instead look at and act upon the available evidence from those countries that have experimented with tgcs e g flanders uk and sweden and design policies that stand a better chance of meeting the criteria of effectiveness efficiency and equity in particular the policies must enable eu to meet the immense innovation industrialisation challenge by inducing the development of a capital goods industry that can eventually diffuse a broad range of technologies that use renewable energy sources only then we can acquire an ability to implement an industrial revolution in the energy system in a way that broadly meets the criteria of effectiveness and dynamic efficiency

the contribution of foreign direct investment to clean energy use carbon emissions and economic growth the paper investigates the contributions of foreign direct investment fdi net inflows to clean energy use carbon emissions and economic growth the paper employs cointegration tests to examine a long run equilibrium relationship among the variables and fixed effects models to examine the magnitude of fdi contributions to the other variables the paper analyzes panel data of 19 nations of the g20 from 1971 to 2009 the test results indicate that fdi has played an important role in economic growth for the g20 whereas it limits its impact on an increase in co2 emissions in the economies the research finds no compelling evidence of fdi link with clean energy use given the results the paper discusses fdi s potential role in achieving green growth goals

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

a degrowth transition pathways for the degrowth niche to replace the capitalist growth regime abstract facing the intertwined environmental social and economic crisis requires us to seriously consider alternatives to the current capitalist system including the emerging concept of degrowth existing understandings of degrowth have focused on characterizing the shape the key elements and the proposals for a degrowth society however its dynamic and evolving nature as an alternative vision of the future and the dynamics of a transition toward degrowth are inadequately considered this paper seeks to address this conceptual gap through a reconceptualisation of degrowth as a radical niche innovation to the capitalist growth regime by extending the multi level perspective framework to the capitalist growth system we undertake a critical reconsideration of the multi level perspective exposing key assumptions of this framework grounded in capitalist economic theory through this we propose a pluriversal potential pathway for change to consider this further a bibliometric analysis is used to measure and visualize research activity in degrowth as a proxy for the processes of development of the degrowth niche then we return to the multi level perspective to consider two potential pathways for change involving the degrowth niche and the capitalist growth regime finally we point to areas for further research that build on this new conceptualisation of a degrowth transition

convergence of per capita carbon dioxide emissions in the eu legend or reality abstract designing appropriate environmental and energy policies in order to meet the kyoto protocol s carbon dioxide co 2 reduction targets in the european union eu requires a detailed examination and thorough understanding of co 2 emission trends across the eu member states this paper investigates whether co 2 emissions have converged across 22 european countries over the 1971 to 2006 period the bayesian shrinkage estimation method is employed to do this work and the results reveal the following first the hypothesis of absolute convergence in per capita co 2 emissions is supported and a slight upward convergence is observed second the fact that countries differ considerably in both their speed of convergence and volatility in emissions makes it possible to identify different groups of countries third the results with respect to convergence do not vary much once the share of industry in gdp is accounted for in a conditional convergence analysis however a decreasing share of industry in gdp seems to contribute to a decline in per capita emissions these findings may carry important implications for both national and eu environmental policies

status and perspectives of renewable energy policy and deployment in the european union what is needed to reach the 2020 targets abstract this article evaluates the status of current res deployment policies and barriers in the eu 27 member states and compares it to the required to meet the 2020 targets the evaluation relies strongly on the quantitative deployment status and policy effectiveness indicators european res deployment and policy has progressed strongly in recent years but the growth here has been mainly driven by effective policies in a small or medium number of top runner countries across europe the highest average policy effectiveness over six years was reached for onshore wind 4 2 biofuels 3 6 and biomass electricity 2 7 while in the heat sector all technologies score below 2 comparing the recent progress to the required growth for meeting the 2020 target it appears that some countries largely exceed the interim targets of the res directive 2009 28 ec despite this europe will need additional policy effort to reach the 2020 target critical success factors include implementing effective and efficient policies that attract sufficient investments reducing administrative and grid related barriers especially in currently less advanced countries upgrading the power grid infrastructure dismantling financial barriers in the heat sector realising sustainability standards for biomass and lowering energy demand through increased energy efficiency efforts

on the economics of renewable energy sources abstract with the global expansion of renewable energy re technologies the provision of optimal re policy packages becomes an important task we review pivotal aspects regarding the economics of renewables that are relevant to the design of an optimal re policy many of which are to date unresolved we do so from three interrelated perspectives that a meaningful public policy framework for inquiry must take into account first we explore different social objectives justifying the deployment of re technologies and review model based estimates of the economic potential of re technologies i e their socially optimal deployment level second we address pivotal market failures that arise in the course of implementing the economic potential of re sources in decentralized markets third we discuss multiple policy instruments curing these market failures our framework reveals the requirements for an assessment of the relevant options for real world decision makers in the field of re policies this review makes it clear that there are remaining white areas on the knowledge map concerning consistent and socially optimal re policies

what governs the transition to a sustainable hydrogen economy articulating the relationship between technologies and political institutions abstract there is a lack of integrated knowledge on the transition to a sustainable energy system the paper focuses on the relationship between technologies and institutions in the field of hydrogen from the perspective of political theory the paper unfolds four paradigms of governance governance by policy networking governance by government governance by corporate business and governance by challenge and looks into the major line of argument in support of these paradigms and into their possible bias with respect to hydrogen options each of these paradigms reveals an institutional bias in that it articulates specific opportunities for collaboration and competition in order to stimulate the transition to a sustainable hydrogen economy the paper makes the observation that there is a compelling need to reframe fashionable discourse such as the necessary shift from government to governance or from government to market instead specific questions with respect to the impact of guiding policy frameworks on innovation will highlight that neither neutral nor optimal frameworks for policy making exist where competing hydrogen options are at stake the identification of paradigms of governance maybe considered a methodological device for participator policy analysis

will history repeat itself economic convergence and convergence in energy use patterns in this paper a difference in differences estimator on panel data for 30 developing and 21 industrialized countries is employed over the period 1971 2005 to examine how patterns of energy use characterized by the consumption of primary energy carriers sectoral energy use and carbon emissions are changing in the process of economic development for the average developing country in our sample the results indicate that economic catch up has been accompanied by above average growth of the use of most primary energy carriers the consumption of final energy in most sectors and total co2 emissions for industrialized countries we find that economic growth is partially decoupled from energy consumption and that above average rates of economic growth were accompanied by larger improvements in energy efficiency these results emphasize the need to identify the relevant engines of economic growth their implications for energy use and possibilities to achieve low carbon growth centered on productivity and efficiency improvements rather than on capital accumulation

a new robustness analysis for climate policy evaluations a cge application for the eu 2020 targets this paper introduces a new method for stochastic sensitivity analysis for computable general equilibrium cge model based on gauss quadrature and applies it to check the robustness of a large scale climate policy evaluation the revised version of the gauss quadrature approach to sensitivity analysis reduces computations considerably vis a vis the commonly applied monte carlo methods this allows for a stochastic sensitivity analysis also for large scale models and multi dimensional changes of parameters in the application an impact assessment of eu2020 climate policy we focus on sectoral elasticities that are part of the basic parameters of the model and have been recently determined by econometric estimation alongside with standard errors the impact assessment is based on the large scale cge model pace we show the applicability of the gauss quadrature approach and confirm the robustness of the impact assessment with the pace model the variance of the central model outcomes is smaller than their mean by order four to eight depending on the aggregation level i e aggregate variables such as gdp show a smaller variance than sectoral output

convergence in energy consumption per capita among asean countries abstract we test for convergence in energy consumption per capita among asean countries over the period 1971 to 2011 using the panel kpss stationarity test and panel lagrange multiplier lm unit root test the results for the panel stationarity and unit root tests with structural breaks find support for energy convergence in asean

accelerating the transition to sustainable energy systems abstract the slow pace of transition to sustainable energy systems is the result of several factors running in parallel the starting points are very low even 30 per annum increases in rated capacity for wind energy or solar pv for example take many years to make a big impact at the global level policy initiatives are for the most part ineffectual in relation to the urgency and scale of what is required and often fail to address the fundamental causes of this slow progress this reflects a top down approach often accompanied by unrealistic targets and simultaneously undermined by a lack of consistency across policies which reflect a utopian social engineering mentality made worse because the planner s response to failure of previous interventions is to do more intensive and comprehensive interventions as william easterly has put it in short there is little or no accountability this approach has failed to harness the sympathy imagination self interest or sound options of energy users although it may attract developers including those not hitherto noted for renewable energy projects or environmental concern targets are usually too short term and clearly unrealistic especially where fossil fuel use is rising very rapidly and renewable energy use expands modestly government subsidies for traditional energy forms continue insufficient attention is paid to what individuals might achieve in energy efficiency and renewable energy terms if permitted to have or retain in industrialized countries where the burden of taxation is often inhibiting the wherewithal to make the necessary investments subsidy systems often promote renewable energy schemes that are misdirected and buoyed up by grossly exaggerated claims one or two mature renewable energy technologies are pushed nationally with insufficient regard for their costs contribution to electricity generation transportation fuels needs or carbon emission avoidance investors are rewarded excessively under some national schemes for mature technologies that should not require support and that frequently do not make the contribution to renewable energy output or carbon emission avoidance they claim costs to business and domestic electricity consumers through the subsidy payments they make are much greater under some schemes than what other carbon abatement measures would cost higher cost less mature renewable energy technologies that have large potential for meeting global energy needs are not getting the support they warrant this is of grave concern given the minimum 30 50 year lead times required to make a large global contribution without departing from the sense of urgency required to address the pressing needs for sustainable energy systems it is imperative that the involvement of people at the grassroots level is harnessed and sound commercial and technical criteria are applied

renewable energy policies in europe converging or diverging abstract nations today are urgently challenged with achieving a significant increase in the deployment of renewable energies in europe that need has given rise to a debate about the most effective and efficient support strategy whilst the different interests debate whether full european harmonisation or strengthening of national support policies for electricity from renewable energy sources res e is the best way forward individual national support schemes are rapidly evolving this study investigates how the eu member states have applied support policy types over the last decade by identifying predominant developments in the application of feed in tariffs premiums tradeable green certificates tax incentives investment grants and financing support for specific technologies wind biomass pv this study shows that europe is currently experiencing certain tendencies towards a bottom up convergence of how national policy makers design res e policy supports while some outliers remain the policy supports of most countries become more similar in the policy types applied dominance of feed in tariffs and in their scope of implementation differentiation for installation sizes and stacking of multiple instruments these trends in national decision making which show tendencies of convergence could make an eu driven top down harmonisation of support either dispensable or at least depending on the agreement less controversial

the merit order effect a detailed analysis of the price effect of renewable electricity generation on spot market prices in germany the german feed in support of electricity generation from renewable energy sources has led to high growth rates of the supported technologies critics state that the costs for consumers are too high an important aspect to be considered in the discussion is the price effect created by renewable electricity generation this paper seeks to analyse the impact of privileged renewable electricity generation on the electricity market in germany the central aspect to be analysed is the impact of renewable electricity generation on spot market prices the results generated by an agent based simulation platform indicate that the financial volume of the price reduction is considerable in the short run this gives rise to a distributional effect which creates savings for the demand side by reducing generator profits in the case of the year 2006 the volume of the merit order effect exceeds the volume of the net support payments for renewable electricity generation which have to be paid by consumers

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

towards a common renewable future the system gmm approach to assess the convergence in renewable energy consumption of eu countries abstract this paper investigates whether the contribution of renewable energy sources to primary energy consumption is characterized by a convergence process across core european union eu countries over the period from 1990 to 2014 the system generalized method of moments gmm methodology is employed for 5 year span panel data of 14 eu members the findings indicate strong evidence for both the absolute unconditional and conditional convergence of renewables share in primary energy consumption across eu 14 countries moreover the control variables namely co2 emissions per gdp fdi inward stock and electricity prices contribute to the speed of convergence hence the implicit rate of conditional convergence is higher than that of absolute convergence the empirical evidence suggests that the energy mixes of core eu members have a tendency to become similar in the long run as the shares of res in primary energy consumption converge to the average level nonetheless it does not necessarily imply that this average would be 20 target which is to be achieved by 2020 according to eu directive 2009 28 ec

a cost benefit analysis of the eu 20 20 2020 package the european commission did not publish a cost benefit analysis for its 2020 climate package this paper fills that gap comparing the marginal costs and benefits of greenhouse gas emission reduction the uncertainty about the marginal costs of climate change is large and skewed and estimates partly reflect ethical choices e g the discount rate the 2010 carbon price in the eu emissions trading system can readily be justified by a cost benefit analysis emission reduction is not expensive provided that policy is well designed a condition not met by planned eu policy it is probably twice as expensive as needed costing one in ten years of economic growth the eu targets for 2020 are unlikely to meet the benefit cost test for a standard discount rate 3 pure rate of time preference the benefit cost ratio is rather poor 1 30 so that benefits need to be very much higher or costs very much lower than typically assumed to justify the 2020 targets only a very low discount rate 0 prtp would justify the 20 emission reduction target for 2020

structural change and convergence of energy intensity across oecd countries 1970 2005 abstract this paper uses new and unique data derived from a consistent framework of national accounts to compute and evaluate energy intensity developments across 18 oecd countries and 50 sectors over the period 1970 2005 we find that across countries energy intensity levels tend to decrease in most manufacturing sectors in the service sector energy intensity decreases at a relatively slow rate with diverse trends across sub sectors a decomposition analysis reveals that changes in the sectoral composition of the economy explain a considerable and increasing part of aggregate energy intensity dynamics a convergence analysis reveals that only after 1995 cross country variation in aggregate energy intensity levels clearly tends to decrease driven by a strong and robust trend break in manufacturing and enhanced convergence in services moreover we find evidence for the hypothesis that across sectors lagging countries are catching up with leading countries with rates of convergence that are on average higher in services than in manufacturing aggregate convergence patterns are almost exclusively caused by convergence of within sector energy intensity levels and not by convergence of the sectoral composition of economies

the eu decarbonisation roadmap 2050 what way to walk we carry out a detailed cge computable general equilibrium analysis of the eu decarbonisation roadmap 2050 on a macroeconomic and on a sectoral level herein we study a reference scenario that implements existing eu policies as well as 3 unilateral and 3 global climate action scenarios we identify global climate action with international emissions trading and the full equalization of co2 prices across all eu sectors as a reasonable policy option to avoid additional costs of the decarbonisation roadmap to a large extent this policy option may include cdm clean development mechanism in the sense of where flexibility in an extended form if there are countries without emissions caps moreover we identify diverse sectoral effects in terms of output investment emissions and international competitiveness we conclude that the successful realization of the eu decarbonisation roadmap probably requires a wise and joint consideration of technology policy design and sectoral aspects

carbon dioxide emissions intensity of portuguese industry and energy sectors a convergence analysis and econometric approach abstract given the relevance of energy and pollution issues for industrialised countries and the importance of industry and energy sectors to the achievement of their economic and environmental goals it is important to know if there is a common pattern of emissions intensity fuel intensity and energy intensity between industries to know if it justifies a more specific application of energy policies between sectors which sectors have the greatest potential for reducing energy use and which are the long term effects of those specific variables on the mitigation of emissions we found that although there is literature on decomposition of effects that affect emissions the study of the convergence and of the relationships between these variables does not include ratios or effects that result from the decomposition analysis thus the above questions are not answered much less for the portuguese reality the purpose of this paper is to study i the existence of convergence of some relevant ratios as carbon dioxide co 2 emissions intensity co 2 emissions by fossil fuel consumption fossil fuel intensity energy intensity and economic structure between industry and energy sectors in portugal and ii the influence that the consumption of fossil fuels the consumption of aggregate energy and gdp have on co 2 emissions and the influence that the ratios in which co 2 emissions intensity decomposes can affect that variable using an econometric approach namely panel corrected standard errors estimator we concluded that there is sigma convergence for all ratios with exception of fossil fuel intensity gamma convergence verifies for all ratios with exception of co 2 emissions by fossil fuel from the econometric approach we concluded that the considered variables have a significant importance in explaining co 2 emissions and co 2 emissions intensity

the eu 20 20 2020 targets an overview of the emf22 assessment three computable general equilibrium models are used to estimate the economic implications of a stylized version of eu climate policy if implemented at the lowest possible cost the 20 emissions reduction would lead to a welfare loss of 0 5 2 0 by 2020 second best policies increase costs a policy with two carbon prices one for the ets one for the non ets could increase costs by up to 50 a policy with 28 carbon prices one for the ets one each for each member state could increase costs by another 40 the renewables standard could raise the costs of emissions reduction by 90 overall the inefficiencies in policy lead to a cost that is 100 125 too high the models differ greatly in the detail of their results the ets non ets split may have a negligible impact on welfare while the renewables standard may even improve welfare the models agree however that the distortions introduced by total eu package imply a substantial welfare loss over and above the costs needed to meet the climate target the marginal total and excess costs reported here are notably higher than those in the impact assessment of the european commission

the world per capita electricity consumption distribution signs of convergence abstract considering residential per capita electricity consumption as one of the most suitable economic welfare indicators the aim of this paper is to explore worldwide differences on this variable over the period 1980 2007 the paper adds to the standard practice of and convergence analysis by tracking the external shape and time evolution of the entire distribution applying nonparametric techniques density functions and stochastic kernels to a sample of 98 countries the main finding is that a weak process of electricity consumption convergence has taken place this reduction of disparities is clearly related to at least three issues firstly the rapid economic changes experienced by some developing countries secondly the energy conservation policies implemented by most developed countries following the first oil shock and thirdly the growing awareness on energy issues in rich countries notwithstanding this the ergodic distribution on per capita electricity consumption indicates that large cross country disparities will persist in the long run

capital in the payments system capital is required to support the payments system in modern economies with well developed financial markets financial innovations raise the marginal product of capital in this usage this suggests that there are general equilibrium consequences associated with an optimal selection of a payments system that includes barter money and a capital based accounting system in this paper goods are differentiated with respect to the medium of exchange associated with their acquisition which is endogenously determined as a consequence of explicit trading frictions the response of the economy to endowment production and payments system shocks including financial innovations is examined copyright 1992 by the london school of economics and political science

state renewable energy electricity policies an empirical evaluation of effectiveness over the past decade state governments have emerged as us energy policy leaders across the country states are adopting policy instruments aimed at carbon mitigation and renewable energy deployment one of the most prevalent and innovative policy instruments is a renewable portfolio standard rps which seeks to increase the share of renewable energy electrification in the electricity market this analysis evaluates the effectiveness of state energy programs with an empirical investigation of the linkage between state rps policy implementation and the percentage of renewable energy electricity generation across states we use a variant of a standard fixed effects model referred to as a fixed effects vector decomposition with state level data from 1998 to 2006 results indicate that rps implementation is not a significant predictor of the percentage of renewable energy generation out of the total generation mix yet for each additional year that a state has an rps policy they are found to increase the total amount of renewable energy generation these findings reveal a potentially significant shortcoming of rps policies political institutions natural resource endowments deregulation gross state product per capita electricity use per person electricity price and the presence of regional rps policies are also found to be significantly related to renewable energy deployment

testing for convergence in carbon dioxide emissions using a century of panel data this paper tests the convergence in per capita carbon dioxide emissions for a collection of developed and developing countries using data spanning the period 1870 2002 for this purpose three recently developed panel unit root tests that permit for dependence among the individual countries are employed the results lend strong support in favor of convergence for the panel as a whole estimates of the speed of this convergence is also provided

the merit order effect of wind and photovoltaic electricity generation in germany 2008 2016 estimation and distributional implications abstract generation from renewable energy sources in germany has experienced a considerable uptake in recent years mainly responsible for this development is the german renewable energy sources act erneuerbare energien gesetz eeg this paper considers redistributive implications of the eeg for different electricity consumers using time series regression analysis we show that electricity generation by wind and pv has reduced spot market prices considerably by 6 mwh in 2010 rising to 10 mwh in 2012 we use these results to build a near term forecasting tool for merit order effects projected to reach 14 16 mwh in 2016 on the other hand the costs of the eeg are passed forward to consumers in the form of a surcharge our findings highlight significant redistributive transfers under the current design of the eeg in particular some energy intensive industries are benefiting from lower wholesale electricity prices whilst being largely exempted from contributing to the costs of the scheme we also highlight implications of our results for other areas for reform of the eeg such as adequate remuneration mechanisms that ensure efficient operation and investment decisions are made under the scheme more generally these findings suggest that policy makers need to integrate distributional assessments into policy design and implementation
