measuring the efficiency of energy intensive industries across european countries abstract this study evaluates the energy efficiency trends of five energy intensive industries in 23 european union eu countries over the period 2000 2009 in particular the performance of the construction electricity manufacturing mining and quarrying and transport sectors is examined the analysis is based on data envelopment analysis dea combined with the malmquist productivity index mpi which allows for distinctions between efficiency and technology changes over time at the second stage of the analysis cross classified multilevel modelling is applied to analyse the main drivers behind efficiency performance using a number of sector and country characteristics based on dea results an overall improvement in efficiency is observed in all sectors over the period the decomposition of the mpi indicates that technology change is primarily responsible for the improvements achieved in most sectors the results obtained by the cross classified model show among other things that the high electricity prices energy taxes and market share of the largest generator in the electricity market have a negative effect on industrial energy efficiency

the relationship between energy consumption structure economic structure and energy intensity in china this paper investigates the long run equilibrium relationships temporal dynamic relationships and causal relationships between energy consumption structure economic structure and energy intensity in china time series variables over the periods from 1980 to 2006 are employed in empirical tests cointegration tests suggest that these three variables tend to move together in the long run in addition granger causality tests indicate that there is a unidirectional causality running from energy intensity to economic structure but not vice versa impulse response analysis provides reasonable evidences that one shock of the three variables will cause the periods of destabilized that followed however the impact of the energy consumption structure shock on energy intensity and the impact of the economic structure shock on energy consumption structure seem to be rather marginal the findings have significant implications from the point of view of energy conservation and economic development in order to decrease energy intensity chinese government must continue to reduce the proportion of coal in energy consumption increase the utilization efficiency of coal and promote the upgrade of economic structure furthermore a full analysis of factors that may relate to energy intensity e g energy consumption structure economic structure should be conducted before making energy policies

energy conservation more effective with rebound policy this article sketches the problem of indirect energy use effects also known as rebound of energy conservation there is widespread support for energy conservation especially when it is voluntary as this seems a cheap way to realize environmental and energy climate goals however this overlooks the phenomenon of rebound the topic of energy rebound has mainly attracted attention from energy analysts but has been surprisingly neglected in environmental economics even though economists generally are concerned with indirect or economy wide impacts of technical change and policies this paper presents definitions and interpretations of energy and environmental rebound as well as four fundamental reasons for the existence of the rebound phenomenon it further offers the most complete list of rebound pathways or mechanisms available in the literature in addition it discusses empirical estimates of rebound and addresses the implications of uncertainties and difficulties in assessing rebound suggestions are offered for strategies and public policies to contain rebound it is advised that rebound evaluation is an essential part of environmental policy and project assessments as opposed to earlier studies this paper stresses the relevance of the distinction between energy conservation resulting from autonomous demand changes and from efficiency improvements in technology equipment in addition it argues that rebound is especially relevant for developing countries

what really matters discounting technological change and sustainable climate this paper discusses the interplay between the choice of the discount rate greenhouse gas mitigation and endogenous technological change neglecting the issue of uncertainty it is shown that the green golden rule stock of atmospheric carbon is uniquely determined but is not affected by technological change more generally it is shown analytically within the framework of a reduced model of integrated assessment that the optimal stationary stocks of atmospheric carbon depend on the choice of the discount rate but are independent of the stock of technological knowledge these results are then reinforced numerically in a fully specified integrated assessment analysis

investigating meso economic rebound effects production side effects and feedback loops between the micro and macro level abstract research on the rebound effect has so far mainly considered micro economic rebound effects at the level of consumers and households as well as macro economic rebound effects in the sense of energy efficiency induced economic growth effects this article focuses on an area of rebound research that has not yet received sufficient attention namely on meso economic rebound effects as production side and sector level rebounds the article summarizes and systematizes reasons why companies generate rebounds distinguishes market and sector level rebounds from macro economic growth effects identifies a number of feedback loops by which production side and sector level rebounds multiply or nullify consumer side rebound effects and finally discusses some conclusions on the potential quantitative dimension of production side rebound effects

understanding the mechanisms through which an influential early childhood program boosted adult outcomes a growing literature establishes that high quality early childhood interventions targeted toward disadvantaged children have substantial impacts on later life outcomes little is known about the mechanisms producing these impacts this paper uses longitudinal data on cognitive and personality traits from an experimental evaluation of the influential perry preschool program to analyze the channels through which the program boosted both male and female participant outcomes experimentally induced changes in personality traits explain a sizable portion of adult treatment effects

economic analysis of energy saving renovation measures for urban existing residential buildings in china based on thermal simulation and site investigation abstract energy saving renovations of existing residential buildings have proven to be very helpful in alleviating the pressure of energy shortages and co 2 emission but an economic analysis of the measures by using a life cycle cost lcc method is very important and necessary to determine whether to implement them or not based on thermal simulation and site investigation the paper uses one urban existing residential building in hangzhou city of china as the subject building and analyzes the economic benefits from the energy saving renovation measures through the lcc method the findings clearly show that the investigation of the factual electricity consumption of the subject building is very important to predict accurately the energy saving effects and financial benefits of the measures for the building because of the great discrepancy between in fact and in thermal simulation of the heating and cool loads and the too cheap electricity price may hamper the development of energy saving implementations in residential sector in china

how financial literacy affects household wealth accumulation this study isolates the causal effects of financial literacy and schooling on wealth accumulation using a new household dataset and an instrumental variables iv approach financial literacy and schooling attainment are both strongly positively associated with wealth outcomes in linear regression models whereas the iv estimates reveal even more potent effects of financial literacy they also indicate that the schooling effect only becomes positive when interacted with financial literacy estimated impacts are substantial enough to imply that investments in financial literacy could have large wealth payoffs

estimating energy conservation potential in china s energy intensive industries with rebound effect abstract the energy consumption of china s six most energy intensive sub industries is about half of the total national energy consumption and accounts for more than 70 of industrial energy consumption in recent years these six industries are capital and energy intensive and have a great impact on the energy consumption of china so they are directly related to the achievement of the energy conservation goal in the 13th five year plan this paper investigates the influential factors of energy consumption in the industries by employing the cointegration method and estimates the possible energy conservation potential considering energy rebound effect the results show that gdp and the scale of industries are the deterministic factors increasing energy consumption while r d intensity decreases it energy price has little impact on energy consumption the average energy rebound effect is calculated using the latent variable approach and the result is 90 75 considering energy rebound effect the energy conservation potential of china s energy intensive industries is 14 18 26 54 million tons of standard coal equivalent in 2020 and 44 64 80 72 million tons of standard coal equivalent in 2030

does energy price affect energy efficiency cross country panel evidence abstract in this paper we analyze the relationship between energy intensity and energy price in a panel of 120 countries over 34 years from 1980 to 2013 we use information on energy intensity and real oil price and merge it with macroeconomic data on the countries structural characteristics we assess their long run relationship and direction of causality using panel cointegration tests and dynamic panel data models we identify a statistically significant but weak negative effect of real oil price on energy intensity which corresponds to a positive effect of energy price on energy efficiency we also show significant large regional differences in this relationship we thus posit that a global policy aimed at increasing the price of oil would induce a limited increase in average energy efficiency through a more efficient use of energy but this increase would differ considerably across regions around the world

the importance of noncognitive skills lessons from the ged testing program it is common knowledge outside of academic journals that motivation tenacity trustworthiness and perseverance are important traits for success in life thomas edison wrote that genius is 1 percent inspiration and 99 percent perspiration most parents read the aesop fable of the tortoise and the hare to their young children at about the same time they read them the story of the little train that could numerous instances can be cited of high iq people who failed to achieve success in life because they lacked self discipline and low iq people who succeeded by virtue of persistence reliability and self discipline the value of trustworthiness has recently been demonstrated when market systems were extended to eastern european societies with traditions of corruption and deceit it is thus surprising that academic discussions of skill and skill formation almost exclusively focus on measures of cognitive ability and ignore noncognitive skills the early literature on human capital e g gary becker 1964 contrasted cognitive ability models of earnings with human capital models ignoring noncognitive traits entirely the signaling literature e g michael spence 1974 emphasized that education was a signal of a one dimensional ability usually interpreted as a cognitive skill most discussions of ability bias in the estimated return to education treat omitted ability as cognitive ability and attempt to proxy the missing ability by cognitive tests most assessments of school reforms stress the gain from reforms as measured by the ability of students to perform on a standardized achievement test widespread use of standardized achievement and ability tests for admissions and educational evaluation are premised on the belief that the skills that can be tested are essential for success in schooling a central premise of the educational testing movement since its inception much of the neglect of noncognitive skills in analyses of earnings schooling and other lifetime outcomes is due to the lack of any reliable measure of them many different personality and motivational traits are lumped into the category of noncognitive skills psychologists have developed batteries of tests to measure noncognitive skills e g robert sternberg 1985 these tests are used by companies to screen workers but are not yet used to ascertain college readiness or to evaluate the effectiveness of schools or reforms of schools the literature on cognitive tests ascertains that one dominant factor g summarizes cognitive tests and their effects on outcomes no single factor has yet emerged to date in the literature on noncognitive skills and it is unlikely that one will ever be found given the diversity of traits subsumed under the category of noncognitive skills studies by samuel bowles and herbert gintis 1976 rick edwards 1976 and roger klein et al 1991 demonstrate that job stability and dependability are traits most valued by employers as ascertained by supervisor ratings and questions of employers although they present no direct evidence on wages and educational t discussants susan mayer university of chicago cecilia rouse princeton university nan maxwell california state university hayward janet currie university of california los angeles

the rebound effect for heavy industry empirical evidence from china abstract energy efficiency improvement will reduce the effective price of energy services and hence at least partially mitigate original expected energy conservation therefore the magnitude of rebound effect is important for the design and timing of an effective energy conservation policy under the framework of translog cost share equations we estimates the direct rebound effect for heavy industry in china for the first time by conducting an empirical research on the relationship between the direct rebound effect and the ease with which energy services can substitute for other inputs additionally asymmetric price responses are specified in the model for the rebound effect estimation empirical results in our paper indicate that the rebound effect for heavy industry in china is about 74 3 this reveals that energy efficiency improvement can save energy to a certain degree since the rebound effect is less than 100 back fire but most of the expected reduction in heavy industry energy consumption is mitigated these findings prove that energy pricing reforms and energy taxes should be further implemented to achieve effective energy conservation in china s 12th five years plan

carbon pricing and energy efficiency improvement why to miss the interaction for developing economies an illustrative cge based application to the pakistan case abstract carbon energy taxes and energy efficiency improvement are studied well in the recent years for their potential adverse impacts on economy especially for lost production and international competitiveness and rebound effects however little attention has been paid to investigate them jointly which can not only prevent fall of energy services cost and thereby rebound effect but reduce the associated macroeconomic costs this study thus employs a 20 sector cge model to explore separately the impacts of carbon tax and its coordinated implementation with energy efficiency improvement on the pakistan economy the country underwent enormous pressure of energy security issues as well as climate change fallouts in the last couple of years and can be regarded as a suitable candidate for energy environmental conservation policies to be considered at a broader context with more concrete efforts the simulation results show that the impact of carbon tax on gdp is negative but resulting reductions in pollutant emissions are relatively high moreover the gdp is expected to grow comparatively positive when analyzed with improvements in energy efficiency with even higher decline in energy consumption demand and so emissions this simultaneous economic and environmental improvement would thus have positive implications regarding sustainable development of the country

the rate of return to the high scope perry preschool program abstract this paper estimates the rate of return to the highscope perry preschool program an early intervention program targeted toward disadvantaged african american youth estimates of the rate of return to the perry program are widely cited to support the claim of substantial economic benefits from preschool education programs previous studies of the rate of return to this program ignore the compromises that occurred in the randomization protocol they do not report standard errors the rates of return estimated in this paper account for these factors we conduct an extensive analysis of sensitivity to alternative plausible assumptions estimated annual social rates of return generally fall between 7 and 10 with most estimates substantially lower than those previously reported in the literature however returns are generally statistically significantly different from zero for both males and females and are above the historical return on equity estimated benefit to cost ratios support this conclusion

competition and allocative efficiency the case of the u s telephone industry this study investigates the effect of competition on the productive efficiency of the u s telephone industry taking into account the fact that the industry was subject to rate of return regulation it is shown that competition induces the incumbents to use capital inputs closer to the unconstrained optima thereby reducing the allocative inefficiency caused by the averch johnson effect this effect is in addition to the usual technical efficiency improvement induced by competition empirical results based on annual data for the u s telephone industry for the 1951 90 period suggested that competition improved the allocative efficiency of the incumbent firms which had been under a rate of return regulation until 1989 copyright 1995 by mit press

total factor energy efficiency of coal consumption an empirical analysis of china s energy intensive industries abstract improvement of coal consumption efficiency is very important both for china in solving its problems of energy security and environmental pollution and for the world in addressing the issue of greenhouse gas emissions using a total factor framework this paper employs a data envelopment analysis dea approach to evaluate the coal consumption efficiency of six energy intensive sub industries in china in 2015 coal consumption efficiency is factorized into economic efficiency and environmental efficiency with sulfur dioxide nitrogen oxide and industrial smoke dust and soot emissions treated as undesirable outputs of energy consumptions the results show the following 1 of the six energy intensive sub industries studied two exhibit both dea effective coal economic efficiency and coal environmental efficiency coal economic efficiency is found to be greater than coal environmental efficiency indicating that the benefits of economic efficiency have masked the negative effects of the environmental impact china should therefore pay more attention to the clean utilization of coal 2 low environmental efficiency mainly resulted from the joint effects of pure technical efficiency and scale efficiency therefore enterprises in these industries must engage in management efforts to improve their ability to manage large enterprises 3 the energy intensive industries characterized by coal environmental efficiency that failed to achieve pure technological effectiveness all exhibited input redundancy or output inadequacy of varying degrees while showing a potential for energy conservation and emissions reductions

energy intensity trend explained for sao paulo state abstract a sectorial analysis and a logarithmic mean divisia index lmdi technique are used in this paper to decompose the energy intensity of the state of sao paulo from 1995 to 2012 into the economic activity effect and the energy efficiency effect this study contributes the following observations 1 the world energy intensity has decreased steadily but the energy intensity of the sao paulo state has been volatile and has declined 2 3 since 1995 2 in the period of study declining energy intensity of the primary and tertiary sectors was observed in contrast the energy intensity of the secondary sector has been gradually increasing 3 the energy efficiency effect was the primary driver of energy intensity change through 2007 and the economic activity effect subsequently had an increasingly more important role in the change 4 the economic structure remained constant until 2004 when the services sector shift became more significant it is hypothesized that the increasing energy intensity from 2005 to 2009 was caused by the growth of inefficient sugarcane bagasse consumption

energy efficiency rebound effects and the environmental kuznets curve technological change is one factor used to justify the existence of an environmental kuznets curve and technological improvements have been argued to be a key factor in mitigating the impacts of economic growth on environmental quality in this paper we use a cge model of the scottish economy to consider the factors influencing the impacts of one form of technological change improvements in energy efficiency on absolute levels of co2 emissions on the carbon intensity of the economy co2 emissions relative to real gdp and the per capita ekc relationship these factors include the elasticity of substitution between energy and non energy inputs responses in the labour market and the structure of the economy our results demonstrate the key role played by the general equilibrium price elasticity of demand for energy and the relative influence of different factors on this parameter

effects of urbanization on energy efficiency in china new evidence from short run and long run efficiency models abstract energy efficiency in china has been the cause for increasing concern for national and local sustainable development due to rapid economic development and large scale energy consumption using panel data of 30 provinces between 1997 and 2016 in china the measurement of energy efficiency is disentangled and the effects of urbanization on different types of energy efficiency are explored first the measurement of energy efficiency is disentangled with long run and short run efficiencies derived results of energy efficiency scores highlight the predominant status of long run inefficiency is low and that disparate energy efficiency is present between provinces second the effects of urbanization were found to be significantly negative on short run long run and overall energy efficiency comparatively the effect of urbanization on long run efficiency was shown to have recently grown implying an urgent call for energy conservation during rapid urbanization finally this study outlines broader implications and suggests policies to improve energy efficiency here application of energy conservation technology industrial structure upgrading and efficiency information disclosure to urban residents are thought to be smart ways to improve energy efficiency

planning and financial literacy how do women fare many older us households have done little or no planning for retirement and there is a substantial population that seems to undersave for retirement of particular concern is the relative position of older women who are more vulnerable to old age poverty due to their longer longevity this paper uses data from a special module we devised on planning and financial literacy in the 2004 health and retirement study it shows that women display much lower levels of financial literacy than the older population as a whole in addition women who are less financially literate are also less likely to plan for retirement and be successful planners these findings have important implications for policy and for programs aimed at fostering financial security at older ages

technological progress and energy rebound effect in china s textile industry evidence and policy implications abstract although energy efficiency improvement can reduce energy consumption reduction of the effective price will also increase the demand for energy services part of this reduction is then offset because of the energy efficiency improvement the magnitude of this energy rebound effect is one of the important factors that must be considered in the formulation and implementation of energy policies the textile industry is a traditional pillar industry in china it is an important part of the national economy and contributes significantly to international trade this study uses the morishima elasticities of substitution mes model combined with asymmetric energy prices trans log cost function and other econometric methods to establish a framework to measure the rebound effect in china s textile industry the empirical results of this paper indicate that the rebound effect for china s textile industry is 20 991 this reveals that energy efficiency improvement is conducive for energy saving to a certain degree notwithstanding these results also prove that energy efficiency improvement is not the only way for china s textile industry to realize energy saving and emission reduction finally based on the analysis future policy priorities are suggested

impacts of regional productivity growth decoupling and pollution leakage abstractimpacts of regional productivity growth decoupling and pollution leakage regional studies this paper examines the issues of decoupling regional economic growth and pollution and the extent to which pollution effects spillover regional national borders specifically a uk regionally disaggregated computable general equilibrium cge model is used to investigate the relationship between economic growth and the level of co2 emissions posited by the environmental kuznets curve ekc conjecture using production accounting principle pap and consumption accounting principle cap environmental accounting methods the simulation results suggest that at the regional level the existence of an ekc relationship depends on the source of regional growth and the how this relationship is specified

international spillover and rebound effects from increased energy efficiency in germany the pollution energy leakage literature raises the concern that policies implemented in one country such as a carbon tax or tight energy restrictions might simply result in the reallocation of energy use to other countries this paper addresses these concerns in the context of policies to increase energy efficiency rather than direct action to reduce energy use using a global cge simulation model we extend the analyses of economy wide rebound from the national focus of previous studies to incorporate international spill over effects from trade in goods and services our focus is to investigate whether these effects have the potential to increase or reduce the overall global rebound of local energy efficiency improvements in the case we consider increased energy efficiency in german production generates changes in comparative advantage that produce negative leakage effects thereby actually rendering global rebound less than national rebound

estimating the rebound effect in us manufacturing energy consumption abstract the energy price shocks of the 1970s are usually assumed to have increased the search for new energy saving technologies where eventual gains in energy efficiencies will reduce the real per unit price of energy services and hence the consumption of energy will rise and partially offset the initial reduction in the usage of energy sources this is the rebound effect which is estimated for the us manufacturing sector using time series data applying the dynamic ols method dols when allowing for asymmetric price effects the rebound effect is found to be approximately 24 for the us manufacturing sector

gradual reforms and the emergence of energy market in china evidence from tests for convergence of energy prices this study investigates the emergence of energy markets by testing for convergence of energy prices with a new dataset on energy spot prices in 35 major cities in china both descriptive statistics and unit root are employed to test the convergence of energy prices for each of four fuel price series the whole study period is divided into two sub periods in order to reconcile the gradual energy reforms the results show the steady improvement in energy market performance in china especially during the second sub period which suggests that the market appears to be playing an increasing role in determining energy prices while panel unit root tests show energy markets are integrated in china as a whole city by city univariate unit root tests suggest that there are still many regional energy markets probably because energy reserves especially coal vary widely across regions since china s energy economy is gradually moving towards market oriented mechanisms the existing literature may become obsolete soon

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

noncognitive abilities and financial distress evidence from a representative household panel this paper provides evidence of how noncognitive abilities affect financial distress in a representative panel of households we find that people in the bottom quintile of noncognitive abilities are 10 times more likely to experience financial distress than those in the top quintile we provide evidence that this relation largely arises from worse financial choices and lack of financial insight by low ability individuals and reflects differential exposure to income shocks only to a lesser degree we mitigate endogeneity concerns using an iv approach and an extensive set of controls implications for policy and finance research are discussed received september 24 2017 editorial decision september 26 2018 by editor stijn van nieuwerburgh authors have furnished an internet appendix which is available on the oxford university press web site next to the link to the final published paper online

rebound effect of improved energy efficiency for different energy types a general equilibrium analysis for china abstract this paper explores the rebound effect of different energy types in china based on a static computable general equilibrium model a one off 5 energy efficiency improvement is imposed on five different types of energy respectively in all the 135 production sectors in china the rebound effect is measured both on the production level and on the economy wide level for each type of energy the results show that improving energy efficiency of using electricity has the largest positive impact on gdp among the five energy types inter fuel substitutability does not affect the macroeconomic results significantly but long run impact is usually greater than the short run impact for the exports oriented sectors those that are capital intensive get big negative shock in the short run while those that are labour intensive get hurt in the long run there is no backfire effect however improving efficiency of using electricity can cause negative rebound which implies that improving the energy efficiency of using electricity might be a good policy choice under china s current energy structure in general macro level rebound is larger than production level rebound primary energy goods show larger rebound effect than secondary energy goods in addition the paper points out that the policy makers in china should look at the rebound effect in the long term rather than in the short term the energy efficiency policy would be a good and effective policy choice for energy conservation in china when it still has small inter fuel substitution

negative rebound and disinvestment effects in response to an improvement in energy efficiency in the uk economy this paper uses a computable general equilibrium cge framework to investigate the conditions under which rebound effects may occur in response to increases in energy efficiency in the uk national economy previous work for the uk has suggested that rebound effects will occur even where key elasticities of substitution in production are set close to zero the research reported in this paper involves carrying out a systematic sensitivity analysis where relative price sensitivity is gradually introduced into the system focusing specifically on elasticities of substitution in production and trade parameters in order to determine conditions under which rebound effects become a likely outcome the main result is that while there is positive pressure for rebound effects even where direct and indirect demands for energy are very price inelastic this may be partially or wholly offset by negative income competitiveness and disinvestment effects which also occur in response to falling energy prices the occurrence of disinvestment effects is of particular interest these occur where falling energy prices reduce profitability in domestic energy supply sectors leading to a contraction in capital stock in these sectors which may in turn lead to rebound effects that are smaller in the long run than in the short run a result that runs contrary to the predictions of previous theoretical work in this area

health insurance and the consumer bankruptcy decision evidence from expansions of medicaid abstract anecdotal evidence and several observational studies suggest that out of pocket medical costs are pivotal in a large fraction of consumer bankruptcy decisions in this paper we assess the contribution of medical costs to household bankruptcy risk by exploiting plausibly exogenous variation in publicly provided health insurance using cross state variation in medicaid expansions from 1992 to 2004 we find that a 10 percentage point increase in medicaid eligibility reduces personal bankruptcies by 8 with no evidence that business bankruptcies are similarly affected we interpret our findings with a model in which health insurance imperfectly substitutes for other forms of financial protection and we use the model to present simple calibration results which illustrate how our reduced form parameter estimate affects the optimal level of health insurance benefits we conclude with calculations which suggest that out of pocket medical costs are pivotal in roughly 26 of personal bankruptcies among low income households

the cost of solar centric renewable portfolio standards and reducing coal power generation using arizona as a case study abstract this paper develops an econometric forecasting system of energy demand coupled with engineering economic models of energy supply the framework is used to quantify the impact of a state level renewable portfolio standard rps achieved predominately with solar generation we perform the analysis using arizona s rps as a case study over the period 2012 2035 we find if arizona implements its rps when supplying future electricity demand there will be an increase in electricity rates relative to a business as usual scenario of reliance on gas fired generation extending the current regime of tax credits greatly reduces this increase at the taxpayers expense we find that by 2025 arizona s rps will implicitly abate carbon dioxide emissions at a cost between 58 and 82 per metric ton and by 2035 abatement costs are between 22 and 69 per metric ton depending on the future evolution of nature gas prices the rps always leads to a negative impact on social welfare under low gas prices but after 2029 the welfare impact is positive under high gas prices in contrast phasing out arizona s existing coal fired generation always has positive welfare impacts

asymmetric impacts of the determinants of energy intensity in nigeria abstract this study analysed the problem of energy intensity determinants in nigeria based on the fully modified ols and canonical cointegration regressions these methods were preferred since they are able to deal effectively with the second order bias problems an often characteristics of time series data the impacts of price of crude oil fdi trade openness and industry structure are asymmetric which suggests the presence of structural effects in parameters the impact of crude oil price is negative but becomes stronger post 1989 saving 126 more in energy consumption relative to pre 1989 also the impacts of fdi and trade openness are negative and significant but become stronger post 1989 saving 11 2 and 0 8 more in energy consumption relative to the baseline respectively for every one percentage point increase in fdi and trade openness the impact of industry value added is positive and significant but weakens after 1989 consuming 1 8 less in energy for every one percentage point increase in industry value added relative to the baseline the energy reducing effect of industry value added post 1989 reflects improvements in the technical characteristics of industrial sector in nigeria last the result showed that the absorptive capability and industry characteristics of nigeria are important determinants of how fdi affects energy intensity this implies that a more integrated fdi programme considering the country characteristics rather than a one fit all programme is preferable

energy intensity and foreign direct investment a chinese city level study article i nfo in this paper we investigate the relationship between the energy intensity of chinese cities and the location of foreign firms employing a unique dataset of 206 of the largest prefecture level cities between 2005 and 2008 our results reveal a non linearinverted u shaped relationship between energy intensity and city level per capita income with the majority of cities on the downward slope of the curve we also find evidence of a significant and negative relationship between the foreign direct investment fdi flows into a city and energy intensity however this effect varies by geographic location reflecting differences in the ability of regions to absorb and benefit from environmental spillovers the relatively small economic effect of fdi can in part explained by the propensity for foreign firms to invest in energy intensive sectors coupled with the trend for china to invest heavily in capital intensive industries

how does your kindergarten classroom affect your earnings evidence from project star in project star 11 571 students in tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade this article evaluates the long term impacts of star by linking the experimental data to administrative records we first demonstrate that kindergarten test scores are highly correlated with outcomes such as earnings at age 27 college attendance home ownership and retirement savings we then document four sets of experimental impacts first students in small classes are significantly more likely to attend college and exhibit improvements on other outcomes class size does not have a significant effect on earnings at age 27 but this effect is imprecisely estimated second students who had a more experienced teacher in kindergarten have higher earnings third an analysis of variance reveals significant classroom effects on earnings students who were randomly assigned to higher quality classrooms in grades k 3 as measured by classmates end of class test scores have higher earnings college attendance rates and other outcomes finally the effects of class quality fade out on test scores in later grades but gains in noncognitive measures persist

the influence of south korean energy policy on opec oil exports abstract south korea is the fifth top oil importer worldwide with 64 of its oil coming from opec member countries over the last 30 years south korea accounted for a rapid increase in energy use this in turn led south korea to be totally dependent on oil imports due to this increase south korea has been experiencing drastic changes in its energy system which could potentially impact its dependence on opec oil import external and internal factors have forced south korea to change its energy strategy and targets these targets would be achieved by reducing its energy intensity and utilizing electricity and renewable energies in order to reduce its dependence on oil consumption low carbon green growth is one policy along with many other energy policies developed by south korea for reducing greenhouse gases thus this policy is receiving a remarkable attention today these national policies along with other international ones are needed to mitigate greenhouse gas emissions and promote other green initiatives this study puts emphasis on these policies as well as uses them to predict the future energy profile of south korea and how these policies will impact on oil imports from opec member countries

do increases in energy efficiency improve environmental quality and sustainability governments world wide increasingly see energy efficiency as an important aspect of sustainability however there is a debate in the literature as to whether the impact of improved energy efficiency on reducing energy use might be partially or more than wholly offset through rebound and backfire effects this paper clarifies the theoretical conditions under which such effects would occur and explores their likely significance using a computable general equilibrium cge model of the scottish economy we find that for scotland a general improvement in energy efficiency in the production sectors of the economy initially produces rebound effects that eventually grow into backfire energy use ultimately increases in response to an efficiency gain and the ratio of gdp to co2 emissions falls the economic factors underpinning rebound effects are straightforward energy efficiency improvements result in an effective cut in energy prices which produces output substitution competitiveness and income effects that stimulate energy demands however the presence of strong rebound or even backfire does not mean that efficiency enhancing policies are irrelevant rather it suggests that such policies operating alone are insufficient to generate environmental improvements the implication is that a co ordinated portfolio of energy policies is required

prices technology development and the rebound effect abstract energy efficiency is the critical parameter for policies that aim at reducing energy consumption while maintaining or even boosting economic growth the two main options to influence energy efficiency are changes in relative prices i e raising the price of energy through economic instruments or to introduce new technologies which increase the productivity of each unit of energy this paper is based on the notion that in an equilibrium economy the marginal economic productivity is identical for all factors i e energy labour knowledge and capital from this premise two main conclusions can be drawn first any change in price or technology will have an impact on the whole economy by creating feedbacks through the substitution of factors of production and goods as well as increased wealth second the two policy approaches changing relative prices and technology development are not opposite to each other they are the two faces of the same reality and should be developed and promoted simultaneously and consistently

how technological efficiency improvements change consumer preferences towards a psychological theory of rebound effects abstract the use of technologies can influence consumer preferences and demand and hence impact on environmental sustainability this article contributes to research on rebound effects which focus on how energy efficiency improvements eei increase energy service demand most of 35 years of rebound research has been analyzed from micro and macro economic perspectives yet micro economic rebound research has so far investigated human behavior only on grounds of simple rational choice models and static assumptions about consumer preferences this article exposes the existing rebound discourse to psychological theories building on considerations of how eei can interfere with processes of decision making it develops a model of how eei via psychological processes may lead to motivational rebound effects as well as to beneficial effects which countervail rebounds the article then advances a typology of such rebound and beneficial effects that not only integrates the typology currently used in the micro economic rebound literature but goes beyond it model and typology explain how economic rebound research could benefit from psychological theory provide the basis for empirically investigating rebound effects on more solid theoretical grounds and empower a comprehensive discussion about policies and measures that aim at a sustainable use of technologies

the impacts of energy prices on energy intensity evidence from china in this paper we present a review of the deregulation of energy prices in china between 1985 and 2004 and assess the impacts of changes in energy prices on aggregate energy intensity and coal oil electricity intensity we used time series data to provide estimates of energy price elasticities empirical results showed that 1 the own price elasticities of coal oil and aggregate energy were negative in periods both before and after 1995 implying that higher relative prices of different energy types lead to the decrease in coal oil and aggregate energy intensities however the positive own price elasticity of electricity after 1995 probably indicates that the price effect was weaker than other factors such as income effect and population effect 2 the impacts of energy prices were asymmetric over time 3 sectoral adjustment also drove the decrease in aggregate energy intensity although raising energy prices to boost efficiency of energy use seems to be an effective policy tool other policy implications concerned with energy prices such as energy supply security and fuel poverty must also be considered

inside information and the own company stock puzzle u s investors allocate 30 40 of their financial asset portfolio in the stock of the company they work for such a portfolio flies in the face of standard portfolio theory which prescribes that an investor should hold less of a financial asset that is positively correlated with her undiversified labor income nevertheless we propose a rational explanation that prescribes a long position in own company stock precisely because the own company stock is positively correlated with the investor s labor income any information the investor learns about her earnings is a partial information advantage in her own company stock when confronted with a choice of what information to acquire employees may choose to learn about their own firm learning lowers the employee s risk of holding own firm equity which raises its risk adjusted returns and makes a long position optimal jel f30 g11 d82

rebound and disinvestment effects in refined oil consumption and supply resulting from an increase in energy efficiency in the scottish commercial transport sector in this paper we use an energy economy environment computable general equilibrium cge model of the scottish economy to examine the impacts of an exogenous increase in energy augmenting technological progress in the domestic commercial transport sector on the supply and use of energy we focus our analysis on scottish refined oil as the main type of energy input used in commercial transport activity we find that a 5 increase in energy efficiency in the commercial transport sector leads to rebound effects in the use of oil based energy commodities in all time periods in the target sector and at the economy wide level however our results also suggest that such an efficiency improvement may cause a contraction in capacity in the scottish refined oil supply sector this disinvestment effect acts as a constraint on the size of rebound effects however the magnitude of rebound effects and presence of the disinvestment effect in the simulations conducted here are sensitive to the specification of key elasticities of substitution in the nested production function for the target sector particularly the substitutability of energy for non energy intermediate inputs to production

water use and economic growth reconsidering the environmental kuznets curve relationship abstract predictions of national and global water use have been criticized for being inaccurate and for not taking into consideration economic development of the little research that does address water use as a function of economic development results are inconsistent but much claims to find clear evidence of an environmental kuznets curves ekc or inverted u type relationship this research attempts to elucidate the relationship between income growth and freshwater use by a evaluating a variety of cross sectional and panel datasets on water withdrawals and consumptive use b employing both traditional least squares and non parametric regression analysis the latter of which offers the advantage of not assuming a given functional form c testing both per capita and total water use and d comparing water withdrawals to consumptive use the research finds some support for the existence of an ekc but results are highly dependent on choice of datasets and statistical technique results are also sector specific and ekc curves prove to be poor indicators of individual country behavior as such the study points to limitations of ekcs in terms of water use policy and planning

how does administrative pricing affect energy consumption and co2 emissions in china despite reforms china still largely applies the cost plus pricing mechanism for the energy sector government administrative energy pricing leads to energy price distortions which could result in not only the excessive and wasteful energy consumption but also environmental deterioration thereby undermining energy conservation and emission abatement using fossil fuel subsidies as a proxy for the level of energy price distortions this paper estimates the subsidy of 22 chinese departments during the period 2006 2010 and adopts the price gap approach to analyze the impacts of subsidy removal on energy consumption and co2 emissions for the various sectors and energy types the results demonstrate that removing energy subsidies would reduce energy consumption and emissions by 3 77 and 2 85 respectively but the effects vary across sectors the transport storage and post sector and the electricity gas and water supply sector are much more affected by energy subsidies removal than other sectors with respect to energy types fuel oil and natural gas are sensitive to subsidies indicating the magnitude of their consumption this suggests that removing subsidies on these fuel types could significantly reduce co2 emissions finally we comprehensively discuss relevant policy issues on energy price formation reform

what cause the decline of energy intensity in china s cities a comprehensive panel data analysis abstract china s progress in energy efficiency has contributed significantly to the reduction in global energy intensity ei but the descending speed of per unit gdp energy consumption in china has been decreasing during recent years the present study aims to investigate the core driving forces of ei from 2005 to 2016 in 289 chinese cities based on granger casualty test and regression analysis for this purpose the study employs panel data analysis with both fixed coefficient and time varying coefficient which are suitable for examining the effects of influence factors on ei and their change trend the granger casualty test investigates that there supposed to be a bidirectional causality between air pollutant emission and energy consumption in china however due to china s weak environmental regulations the negative effect of emission on ei is not significant further regression analysis shows that a percentage increase in electricity price decreases ei by 0 722 in long term but this adjustment takes time furthermore analysis of short term relationship reveals that optimizing energy structure may be the best way for china to reduce ei in short run finally the time varying coefficients of panel data model indicate that inhibitory effect of promoting electricity consumption on ei will keep improving with expansion of electricity use

time preference noncognitive skills and well being across the life course do noncognitive skills encourage healthy behavior a number of prominent diseases are influenced by health behaviors for example it is well known that the decision to smoke comes with considerable risks of developing smoking related ailments such as lung cancer emphysema and heart disease obesity is another health condition that can be costly it is associated with increased risk for diseases such as coronary heart disease and diabetes centers for disease control 2009 nationally it is estimated that about one third of the u s population is obese and estimates suggest that obesity costs society anywhere from 27 to 47 billion in health care expenditures annually centers for disease control 2009 national center for health statistics 2008 research suggests that changing individuals diets and getting them to exercise would help to reduce the prevalence of obesity in society melayne mcinnes and judith shinogle 2009 smoking and obesity provide just two examples of cases in which the nation s burden of disease is influence by behaviors that its citizens engage in because the united states spends a large share of gdp on health care each year understanding the determinants of health behaviors is important as it may allow scholars to identify ways to reduce these costs this paper examines the relationship between individuals health behaviors and the non cognitive skills that individuals possess in the past decade the economics discipline has seen a burst of interest in human capabilities that contribute to labor market productivity beyond the usual foci of attention levels of education and learning by doing the collection of personality traits soft skills incentive enhancing preferences and socio emotional factors that economists are now studying has been loosely grouped together under the heading non cognitive skills 1 while the term may be something of a misnomer because many of the worker attributes that the authors writing in this subfield are interested in require reasoning or cognition the skills of interest have been found to be important determinants of labor market success james heckman jora stixrud and sergio urzua 2006 samuel bowles herbert gintis and melissa osborne 2001 2james heckman 2007 has stated that these socio emotional attributes as non cognitive skills are sometimes called are also likely to affect health behaviors this paper tests this hypothesis it provides a theoretical and an empirical analysis of the connection between socio emotional attributes and the choices that individuals make about health it uses data from a large nationally representative dataset to analyze the relationships

implications of rational inattention abstract a constraint that actions can depend on observations only through a communication channel with finite shannon capacity is shown to be able to play a role very similar to that of a signal extraction problem or an adjustment cost in standard control problems the resulting theory looks enough like familiar dynamic rational expectations theories to suggest that it might be useful and practical while the implications for policy are different enough to be interesting

path analysis of factors impacting china s co2 emission intensity viewpoint on energy abstract to explore the means of achieving carbon intensity targets in china this study empirically discusses the key factors influencing the co2 emission intensity and the causal relationships among these factors based on a path analysis using panel data six factors are included in the analysis gross domestic product gdp per capita a technology effect te energy price ep industrial structure is energy structure es and foreign direct investment fdi the study period is divided into three stages 1991 2002 2003 2014 and 1991 2014 improving t is the most significant way to decrease the emission intensity followed by fdi in each stage the effects of a ep es and fdi on the emission intensity mainly come from indirect contributions through te and is and the effects of te and is arise primarily through direct contributions improving a promotes the development of te in each stage and the adjustment of is in 1991 2002 but increases the proportion of secondary industry in 2003 2014 a rising ep negatively affects te in 2003 2014 improving the fdi promotes the development of te in each stage but is not conducive to the adjustment of is in 2003 2014

debt and depression causal links and social norm effects individuals exhibiting problems repaying their debt obligations also exhibit much worse psychological health selection into problem debt on the basis of poor psychological health accounts for much of this difference the causality between problem debt and psychological health may be two way using individual level uk panel data local house price movements exogenous to individual households are used to establish the causality from problem mortgage debt to psychological health in addition the social norm effects of problem debt are investigated using local bankruptcy and repossession rates results indicate there are sizeable causal links and social norm effects in the debt psychological health relationship language en

the sufficiency strategy would rich world frugality lower environmental impact abstract one alleged weapon against unsustainable environmental impact is for the wealthy to consume less this sufficiency strategy is to complement the efficiency strategy of lowering ratios of resource inputs to economic outputs the former would reduce the affluence factor in i pat the latter the technology factor that the latter strategy suffers from a consumption rebound is widely recognized this paper identifies a similar rebound when the affluence factor is autonomously lowered the lower initial demand lowers prices which in turn stimulates new demand by others the strategy moreover addresses only the rich raising questions of its theoretical maximum efficacy its proponents usually conflate frugality with the north south dichotomy and intra generational with inter generational equity moreover there are difficulties with the supporting arguments that frugality is good for one s own sake as well as for the environment and that the rich should lead the way to living more lightly personal behaviour change is furthermore not a substitute for international political efforts finally since all changes in right side factors of the i pat equation change other right side factors such indirect attacks on impact should be abandoned in favor of supply and emissions quotas
