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 energy transition of the transition economies an empirical analysis the aggregate manufacturing energy intensity of 28 countries in eastern europe and central asia had declined by 35 percent during 1998 2008 this study reveals strong evidence of convergence less efficient countries improved more rapidly and the cross country variance in energy productivity narrowed over time an index decomposition analysis indicates that energy intensities declined largely because of more efficient energy use rather than shifts from energy intensive to less intensive manufacturing activities income growth and energy price increases were the main drivers of the convergence they dominated the impact of trade which led to specialization in energy intensive industries

environmental regulation technological innovation and energy consumption a cross region analysis in china abstract china has encountered the environmental issues and energy pressures in the middle income stage strengthening environmental regulation is a crucial measure to prevent environment deterioration and energy dilemma this paper investigates the three types of environmental regulations on energy consumption using feasible generalized least squares method during 1997 2015 in direct and indirect path the main conclusions are as follows in the direct path the economical and supervised types of environmental regulations have inhibited energy consumption whilst legal environmental regulation has no significant impact as for indirect path the rebound effect of energy is greater than the energy conservation generated by technological innovation which is embodied as an inhibitory effect the effects of environmental regulation display regional difference the legal and supervised types of environmental regulations have significant cost effect and rebound effect on energy consumption in the entire samples on the contrary the economical environmental regulation shows the opposite sigh in eastern regions the counterfactual simulation results show that the net effects of environmental regulations on energy consumption are negative which is beneficial for relieving energy pressures based on the findings this paper provides pertinent policy implications

longitude matters time zones and the location of foreign direct investment abstract using bilateral foreign direct investment fdi data we find that differences in time zones have a negative and significant effect on the location of fdi we show that this finding is robust across different specifications estimation methods and proxies for time zone differences time zones also have a negative effect on trade but this effect is smaller than that on fdi finally the impact of the time zone effect has increased over time suggesting that it is not likely to vanish with the introduction of new information technologies

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

why did the energy intensity fall in china s industrial sector in the 1990s the relative importance of structural change and intensity change there have been a variety of studies investigating the relative importance of structural change and real intensity change to the change in china s energy consumption in the 1980s however no detailed analysis to date has been done to examine whether or not the increased energy efficiency trend in the 1980s still prevailed in the 1990s this article has filled this gap by investigating the change in energy consumption in china s industrial sector in the 1990s based on the data sets of value added and end use energy consumption for the 29 industrial subsectors and using the newly proposed decomposition method of giving no residual our results clearly show that the overwhelming contributor to the decline in industrial energy use in the 1990s was the decline in real energy intensity indicating that the trend of real energy intensity declines in the 1980s at the 2 digit level was still maintained in the 1990s this conclusion still holds even if we lower the growth rate dramatically in line with the belief that the growth rate of china s gdp may be overestimated

under the cover of darkness how ambient light influences criminal activity abstract we exploit daylight saving time dst as an exogenous shock to daylight using both the discontinuous nature of the policy and the 2007 extension of dst to consider the impact of light on criminal activity regression discontinuity estimates show a 7 decrease in robberies following the shift to dst as expected effects are largest during the hours directly affected by the shift in daylight we discuss our findings within the context of criminal decision making and labor supply and estimate that the 2007 dst extension resulted in 59 million in annual social cost savings from avoided robberies

the influential factors of china s regional energy intensity and its spatial linkages 1988 2007 abstract a large amount of literature on china s energy intensity seldom considers the regional differences of energy intensity inside china and the spatial effects based on spatial statistics methods this paper explores the regional imbalance of china s provincial energy intensity and the spatially correlation of energy intensity among provinces using spatial panel data models this paper finds that gdp per capita transportation infrastructure the level of marketization and scientific and technological input significantly reduce the energy intensity the ratio of heavy industries to total industries and the ratio of coal consumption to total energy consumption significantly expand the energy intensity meanwhile the coefficient of the ratio of export to gdp is not significant then the spillover and convergence of china s regional energy intensity have been tested the results indicate that the spillover effect between the eastern and western china is remarkable and there exist absolute convergence of provincial energy intensity moreover gdp per capita transportation infrastructure the level of marketization and scientific technological input are conducive to conditional convergence after the spatial effects are controlled according to the empirical results this paper proposes some policy suggestions on reducing china s energy intensity

the energy intensity of transition countries the economies of central and eastern europe and the former soviet union have traditionally been very energy intensive energy intensity defined as energy use per gdp has decreased in the course of transition but progress has been uneven and most transition countries still use several times as much energy per unit of output as their western peers this paper decomposes energy data to identify the main factors behind the improvements in energy intensity it shows that energy prices and progress in enterprise restructuring are the two most important drivers for more efficient energy use

sleep and the allocation of time using aggregated data for 12 countries a cross section of microeconomic data and a panel of households we demonstrate that increases in time in the labor market reduce sleep our theory of the demand for sleep differs from standard models of time use by assuming that sleep affects wages by affecting labor market productivity estimates of a system of demand equations demonstrate that higher wage rates reduce sleep time among men but increase their waking nonmarket time by an equal amount among women the wage effect on sleep is negative but very small

saving babies revisiting the effect of very low birth weight classification we reconsider the effect of very low birth weight classification on infant mortality we demonstrate that the estimates are highly sensitive to the exclusion of observations in the immediate vicinity of the 1 500 g threshold weakening the confidence in the results originally reported in almond doyle kowalski and williams 2010

sunset time and the economic effects of social jetlag evidence from us time zone borders abstract the rapid evolution into a 24 h society challenges individuals ability to conciliate work schedules and biological needs epidemiological research suggests that social and biological time are increasingly drifting apart social jetlag this study uses a spatial regression discontinuity design to estimate the economic cost of the misalignment between social and biological rhythms arising at the border of a time zone in the presence of relatively rigid social schedules e g work and school schedules exploiting the discontinuity in the timing of natural light at a time zone boundary we find that an extra hour of natural light in the evening reduces sleep duration by an average of 19 minutes and increases the likelihood of reporting insufficient sleep using data drawn from the centers for disease control and prevention and the us census we find that the discontinuity in the timing of natural light has significant effects on health outcomes typically associated with circadian rhythms disruptions e g obesity diabetes cardiovascular diseases and breast cancer and economic performance per capita income we provide a lower bound estimate of the health care costs and productivity losses associated with these effects

energy intensity developments in 40 major economies structural change or technology improvement this study analyzes energy intensity trends and drivers in 40 major economies using the wiod database a novel harmonized and consistent dataset of input output table time series accompanied by environmental satellite data we use logarithmic mean divisia index decomposition to 1 study trends in global energy intensity between 1995 and 2007 2 attribute efficiency changes to either changes in technology or changes in the structure of the economy and 3 highlight sectoral and regional differences we first show that heterogeneity within each sector across countries is high these general trends within the sectors are dominated by large economies first and foremost the united states in most cases heterogeneity is lower within each country across the different sectors regarding changes of energy intensity at the country level improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries notable exceptions are japan the united states australia taiwan mexico and brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction

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

sustainability of catch up growth in the extended european union abstract this paper analyses the compatibility of growth and sustainability in the european union eu including a new eu member states from the former soviet bloc eu 10 the extension of eu borders financial and technological support stimulated rapid convergence and decreased the socio economic differences between the old eu 15 and newly accepted eu member states the transition from a command to a market economy resulted in the remarkable increase in resource efficiency and other positive aspects of sustainability along with 1 5 times increased gdp final energy consumption decreased by 20 greenhouse gases emissions by 25 and the emissions of acidifying compounds were halved during the period from the collapse of former soviet bloc to the recent economic crisis however the per capita production and consumption in eu 10 is still approximately half that of eu 15 and further catch up growth should be expected ensuring that economic and social cohesion is not achieved at the expense of increased environmental impact decelerated economic growth is a feature characteristic of mature economies and the gdp growth rate in eu 15 states decreased almost 2 5 times during the last 50 year similar trends are characteristic of other developed countries and market economies have adapted to this trend even with a decelerated growth rate the ecological footprint in developed countries currently exceeds three and more times the allowable limits and almost two thirds of the ecological footprint relates to traditional energy de fossilisation by a greater increase in energy efficiency use of renewable energy and more intense material recovery is the most promising option for reducing the ecological footprint of these countries deceleration of the economic growth rate supplemented by the aforementioned options is a hard but realistic track leading to the reduction of ecological footprint in developed countries to allowable limits without radical de growth in consumption and production that can result in unpredictable and unacceptable consequences

a marginal measure of energy efficiency the shadow value abstract economists are well aware of the importance of marginal versus average measures of energy efficiency yet in the energy literature there is no consensus on the appropriate method for defining and measuring energy efficiency this paper sets out the shadow value of energy as a proper and meaningful marginal energy efficiency index a restricted profit function is used to model the shadow value we explore four scenarios to characterize and evaluate the shadow value of energy a within country comparison of different production processes with different energy requirements a comparison of different countries with different resource endowment a government policy to impose a tax to alter the shadow value to address environmental issues and a within country comparison of externalities arising from two sources of energy a comparative static analysis is carried out to sign the functional arguments defined for the shadow value

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

an empirical analysis of energy intensity and the role of policy instruments abstract the reduction of energy intensity is important for sustainable economic growth especially in non oecd countries where energy demand growth is high understanding the impact of policies on energy intensity can help policy makers to reduce energy intensity using empirical methods and cross country data from 44 countries over the period 1990 2016 we study the determinants of energy intensity the common correlated effects mean group estimator is employed since it addresses nonstationarity cross sectional dependence and heterogeneity all three of which exist in the data both gdp per capita and economy wide energy prices are shown to be negatively associated with energy intensity the empirical results provide evidence that several policy instruments are effective in reducing energy intensity i standards and labeling ii government direct investment iii strategic planning and support iv fiscal measures taxes and v grants and subsidies the duration of the policy is more important than the mere existence of the policy in demonstrating the policy s effectiveness

limited attention and income distribution economists have long been interested in the idea that there is a direct circular relation between poverty and low productivity and not just one that is mediated by market failures usually in asset markets the nutrition based efficiency wage model partha dasgupta and debraj ray 1987 is the canonical example of models where this happens however it has been variously suggested see for example t n srinivasan 1994 that the link from nutrition to productivity and especially the link from productivity to nutrition is too weak to be any more than a small part of the story partha dasgupta himself acknowledges this when he writes nutrition productivity construct provides a metaphor for an economic environment harboring poverty traps partha dasgupta 1997 page 5 we propose an alternative approach to this question based on the idea that attention is a scarce resource that is important for productivity specifically people may not be able to fully attend to their jobs if they are also worrying about problems at home and being distracted in this way reduces productivity but not paying attention at home is also costly early symptoms of a child s sickness may go unnoticed water may run out at the end of the day kerosene for lighting lamps at home might run out and make it hard to do homework etc finally the extent to which home life distracts depends on the nature of home life specifically certain goods e g a good baby sitter a 24 hour piped water supply a connection to a power supply grid can reduce the extent of home life distraction these three assumptions generate an interesting relation between income and productivity that is at the core of our model the non poor in this model by virtue of owning distraction saving goods and services at home are able to focus more on their work hence they will be more productive at work and will be able to afford more distraction saving goods this simple two way relationship between in this abstract was borrowed from another version of this item

regional analysis across colombian departments a non parametric study of energy use abstract the analysis of energy use is important in emerging economies and especially in the manufacturing industries as energy is a key factor of sustainable development this research analyses and evaluates the features of regional energy use and efficiency across colombian departments in the manufacturing industries for the period between 2005 and 2013 by applying two malmquist data envelopment analysis models the results indicate significant difference in energy use and efficiency across colombian departments in the manufacturing industries the results of the malmquist indexes determine that various manufacturing industries across colombian departments have a high potential to increase energy efficiency several manufacturing industries across colombian departments have experienced gains in productivity a growth in efficiency an improvement in the relationship between inputs and outputs and scale production and advances in innovation through new technologies this technique allows to make comparisons and improves energy policies to increase energy efficiency and decrease co 2 emissions the application of panel data models indicate that increases in energy prices exports and productivity lead to better energy use while a higher presence of energy intensive sectors and small and medium enterprises across colombian departments reduce energy efficiency the methods selected in this research generated consistent robust and reliable estimates related to energy use and co 2 emissions for regional studies the findings of this study indicate that diverse energy policies should implement in the industrial sector across colombian departments and that they should contribute to improvements in energy use especially in small and medium companies and energy intensive sectors

coping with the upheavals of globalization in the shea value chain the maintenance and relevance of upstream shea nut supply chain organization in western burkina faso summary market globalization has had only a weak impact on the regional shea nut supply chain in western burkina faso despite the boom in the shea trade and the arrival of leading foreign firms we show that despite the fact that wholesalers have kept the shea chain locked in an oligarchic organization for the last 50 years they still play an important role in the smooth functioning of the chain and in profit sharing down the chain to the rural poor we suggest that development actors should consider shea traders and their role in the coordination of the chain more carefully 2014 the authors published by elsevier ltd this is an open access article under the cc by nc sa license http creativecommons org licenses by nc sa 3 0
