monitoring changes in economy wide energy efficiency from energy gdp ratio to composite efficiency index since the 1973 world oil crisis monitoring trends in energy efficiency at the economy wide level has been an important component of energy strategy in many countries to support this effort various energy efficiency related indicators have been developed we examine some classical indicators which are often found in national and international energy studies in the 1970s and 1980s we then describe the recent developments in using the index decomposition analysis to give an economy wide composite energy efficiency index based on a bottom up approach this composite index is superior to the classical indicators as an economy wide energy efficiency measure and has lately been adopted by a growing number of countries for national energy efficiency trend monitoring

unobserved heterogeneity in stochastic cost frontier models this paper applies a number of stochastic cost frontier models to a panel data set and compares their ability to distinguish unobserved heterogeneity from inefficiency variation among firms the main focus is on greene s 2005 panel data model that incorporates firm specific effects in a stochastic frontier framework in cases where the unobserved heterogeneity is correlated with explanatory variables while the random effects estimators can be biased the fixed effects model may overestimate inefficiency in line with mundlak a simple method is proposed to include such correlations in random effects specification the sample includes 36 swiss nursing homes operating from 1993 to 2001 the results suggest that the proposed specification can avoid the inconsistency problem while keeping the inefficiency estimates unaffected

market related reforms and increased energy efficiency in transition countries empirical evidence energy efficiency improvement is a desirable response to growing climate change and security of energy supply concerns this article studies the impacts of a varied set of macro level market oriented reforms as well as structural change on economy wide measure of energy efficiency across a group of the transition countries these countries experienced a rapid marketization process which since the early 1990s transformed their economies from central planning towards market driven models we use a bias corrected fixed effect analysis technique to estimate this effect for the period 1990 to 2010 the results suggest that reforms aimed at market liberalization financial sector and most infrastructure industries drove energy efficiency improvements we find significant differences in improvements in energy efficiency between transitional central european and baltic states south east europe ones and the commonwealth of independent states the reasons for these differences are also discussed

technology invention and diffusion in residential energy consumption a stochastic frontier approach traditional large appliances absorb a large share of residential electricity consumption and represent important targets of energy policy strategies aimed at achieving energy security despite being characterized by rather mature technologies this group of appliances still offers large potential in terms of efficiency gains due to their pervasive diffusion in this paper we analyse the electricity consumption of a set of four traditional white goods in a panel of ten eu countries observed over 21 years 1990 2010 with the aim of disentangling the amount of technical efficiency from the overall energy saving the technical efficiency trend is modelled through a set of technology components representing both the invention and adoption process by the means of specific patents weighted by production and bilateral import flows which allows to overcome the rigid stochastic frontier framework in modelling the effect of technical change our results show that the derived energy demand and inefficiency trends are both related to changes in the amount of available technology embodied in energy efficient appliances the effect is significant both in its domestic and international components and suggests an active role of innovation and trade policies for achieving efficiency targets which directly impact the amount of electricity consumed by households

regional green development level and its spatial relationship under the constraints of haze in china abstract this paper includes the new constraints of haze in the environmental efficiency research framework and the sbm undesirable and malmquist exponential models are used to measure and analyse the evolution characteristics and regional differences of regional green environmental efficiency of china and applied china s regional panel data and a spatial dubin model to deeply explore the impact of environmental regulation openness urbanisation industrial structure and technological innovation on regional green environmental efficiency the result show that under the constraints of smog the regional green environment efficiency of china is different with each area and shows strong spatial dependence and spatial differentiation the overall spatial distribution of the east middle northeast west gradient is decreasing environmental regulation had a major impact on the green environment efficiency of the region and demonstrated an inverted n type relationship the degree of openness urbanisation industrial structure and technological innovation play an active role in promoting regional green sustainable development economic growth corporate ownership structure fiscal policy and foreign investment dependence have hindered the progress of regional green sustainable development to a certain extent

measuring energy performance with sectoral heterogeneity a non parametric frontier approach abstract evaluating economy wide energy performance is an integral part of assessing the effectiveness of a country s energy efficiency policy non parametric frontier approach has been widely used by researchers for such a purpose this paper proposes an extended non parametric frontier approach to studying economy wide energy efficiency and productivity performances by accounting for sectoral heterogeneity relevant techniques in index number theory are incorporated to quantify the driving forces behind changes in the economy wide energy productivity index the proposed approach facilitates flexible modelling of different sectors production processes and helps to examine sectors impact on the aggregate energy performance a case study of china s economy wide energy efficiency and productivity performances in its 11th five year plan period 2006 2010 is presented it is found that sectoral heterogeneities in terms of energy performance are significant in china meanwhile china s economy wide energy productivity increased slightly during the study period mainly driven by the technical efficiency improvement a number of other findings have also been reported

fuel tourism in border regions the case of switzerland this paper explores the issue of fuel tourism in switzerland for the period 1985 1997 a panel data model for the border regions of switzerland italy france and germany is estimated the results show a significant impact of the gasoline price differential on demand suggesting that a decrease of 10 in the swiss gasoline price leads to an increase in demand in the border areas of nearly 17 5 it is shown that fuel tourism accounted for about 9 of overall gasoline sales in the three regions during the period 1985 1997 and that the recently proposed swiss co2 tax might given current conditions eliminate net fuel tourism

us residential energy demand and energy efficiency a stochastic demand frontier approach this paper estimates a us frontier residential aggregate energy demand function using panel data for 48 states over the period 1995 to 2007 using stochastic frontier analysis sfa utilizing an econometric energy demand model the in efficiency of each state is modeled and it is argued that this represents a measure of the inefficient use of residential energy in each state i e waste energy this underlying efficiency for the us is therefore observed for each state as well as the relative efficiency across the states moreover the analysis suggests that energy intensity is not necessarily a good indicator of energy efficiency whereas by controlling for a range of economic and other factors the measure of energy efficiency obtained via this approach is this is a novel approach to model residential energy demand and efficiency and it is arguably particularly relevant given current us energy policy discussions related to energy efficiency

the decline in the number of school districts in the u s 1950 1980 between 1950 and 1980 the number of school districts fell from 83 642 to 15 987 data for the fifty states for 1950 1960 1970 and 1980 are used to identify the factors that contributed to this decline the focus is on the tradeoff between cost savings through scale economies a few large districts and a diverse population s demand for choice in public schooling many small districts we find that much of the decline in the number of school districts has resulted from 1 the decline in the farm population and increase in population density which has made it easier to take advantage of scale economies 2 the growing importance of state aid which reduces quality variation among districts within a state and 3 the increase in the fraction of teachers that belong to the national education association teacher s union which may reflect increased political influence used to lower the costs of organizing

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

a new approach to measuring the rebound effect associated to energy efficiency improvements an application to the us residential energy demand this paper brings attention to the fact that the energy demand frontier model introduced by filippini and hunt 2011 2012 is closely connected to the measurement of the so called rebound effect associated with improvements in energy efficiency in particular we show that their model implicitly imposes a zero rebound effect which contradicts most of the available empirical evidence on this issue we relax this restrictive assumption through the modelling of a rebound effect function that mitigates or intensifies the effect of an efficiency improvement on energy consumption we illustrate our model with an empirical application that aims to estimate a us frontier residential aggregate energy demand function using panel data for 48 states over the period 1995 to 2011 average values of the rebound effect in the range of 56 80 are found therefore policymakers should be aware that most of the expected energy reduction from efficiency improvements may not be achieved

a model of optimal plant size with an application to the demand for cognitive achievement and for school size a model of optimal plant size is developed which predicts that 1 plants experience increasing returns to in plants inputs 2 the relative price of plant output is greater in rural areas than in urban areas and 3 plants are larger in urban areas than in rural areas the model s predictions appear to be consistent with behavior in a number of consumer services e g grocery movie and library services these predictions are more rigorously tested and are strongly supported when demand functions for cognitive achievement and for school size are estimated these regressions also lend support to the quality quantity model of fertility

modelling oecd industrial energy demand asymmetric price responses and energy saving technical change abstract the industrial sector embodies a multifaceted production process consequently modelling the derived demand for energy is a complex issue made all the more difficult by the need to capture the effect of technical progress of the capital stock this paper is an exercise in econometric modelling of industrial energy demand using panel data for 15 oecd countries over the period 1962 2003 exploring the issue of energy saving technical change and asymmetric price responses although difficult to determine precisely it is tentatively concluded that the preferred specification for oecd industrial energy demand incorporates asymmetric price responses but not exogenous energy saving technical change

does restricting choice in referenda enable governments to spend more if school boards represent the preferences of the median voter referendums to approve school expenditures should not constrain school expenditures if school boards would choose expenditures larger than the median voter s preference referendums that restrict voters to approving or disapproving a school board s recommended expenditure level will result in expenditures larger than the median voter would prefer however florida used a unique referendum system which guaranteed the median voter s most preferred outcome using florida education expenditures as a benchmark the evidence suggests that spending was slightly higher in restricted choice referendum states than in florida

efficiency assessment of hydroelectric power plants in canada a multi criteria decision making approach abstract hydropower plays a major role in the canadian electricity generation industry few attempts have been made however to assess the efficiency of hydropower generation in canada this paper analyzes the overall efficiency of hydropower generation in canada from comprehensive viewpoints of electricity generating capability its profitability as well as environmental benefits and social responsibility using the topsis the technique for order preference by similarity to ideal solution method the factors that influence the efficiency of the hydropower generation are also presented to help to the sustainable hydropower production in canada the most important results of this study concern 1 the pivotal roles of energy saving and of the social responsibility in the overall efficiency of hydropower corporates and 2 the lower hydropower generation efficiency of some of the most important economic regions in canada other results reveal that the overall efficiency of hydropower generation in canada experienced an improvement in 2012 following a downtrend from 2005 to 2011 amidst these influencing factors energy saving and social responsibility are key factors in the overall efficiency scores while management defined herein by the number of employees and hydropower stations of a corporation has only a slightly negative impact on the overall efficiency score

correcting the uneven burden sharing of emission reduction across provinces in china abstract although china committed to reduce its energy and emission intensity the allocation of such national targets in the provincial level is still a political negotiation process and lack of a systematic principle from the perspective of efficiency this paper proposes an allocation principle based on the efficiency levels the efficiency levels are estimated by employing a stochastic frontier analysis approach and the links between energy intensity and efficiency are constructed the results show that energy efficiency change is not the major contributor to energy intensity reduction furthermore this analysis indicates that i the efficiency based allocation can distribute reduction burdens among regions smoothly compared to the intensity based allocation and ii the national target of emission intensity reduction can be achieved solely through efficiency measures

evidence on the impact of state government on primary and secondary education and the equity efficiency trade off abstract state governments may affect the productivity of primary and secondary education in two ways first various regulations imposed on local school districts are expected to make schools less efficient second state efforts to reduce inequality in education spending make it more difficult for voters to increase school quality which should lead to less voter monitoring of schools and thus less efficient schools our empirical analysis of state scholastic aptitude test sat scores from 1987 to 1992 provides evidence on both effects the state s revenue share which captures state meddling in local decisions has the expected negative impact on school efficiency but our novel result is that state induced spending equalization also lowers average test scores but has had little if any effect on reducing the disparity in student achievement these results bring into question policy efforts designed to shift education responsibilities from local governments to state and federal governments

a review of time use models of residential electricity demand residential electricity demand in most european countries accounts for a major proportion of overall electricity consumption the timing of residential electricity demand has significant impacts on carbon emissions and system costs this paper reviews the data and methods used in time use studies in the context of residential electricity demand modelling it highlights key issues which are likely to become more topical for research on the timing of electricity demand following the roll out of smart metres

been top down so long it looks like bottom up to me abstract while technologists emphasize suboptimal choices by individuals and organizations many economists have ignored behavior exhibiting technical inefficiency this paper selectively discusses efforts by some economists to identify and measure technical inefficiency as applied to the energy efficiency gap bottom up economics would seek to measure significant departures from best practice technology distinguish between inefficiency that is more less wasteful of energy than other inputs and focus on developing testable hypotheses about technical inefficiency support for widespread intervention in energy use decisions may not necessarily follow from such an inquiry

the legacy of serrano the impact of mandated equal spending on private school enrollment 1 introduction the california supreme court decision in serrano v priest in 1971 was the first state supreme court ruling to declare a state s education finance system unconstitutional 1 the suit originally filed by a class of los angeles county public school children and their parents argued that the california public school finance system was unconstitutional because of its reliance on a local property tax system under this system large differences in property wealth created enormous variations in educational resources across the state in its subsequent 1976 serrano h decision the california supreme court found that the state legislature s response to the first serrano decision was insufficient the court ordered the state legislature to follow a trial court s requirement to implement a funding formula that reduces wealth related per pupil expenditure disparities i e property tax revenue exclusive of categorical aid and special needs to 100 across school districts the serrano ii decision resulted in a nearly complete shift of the fiscal responsibility for k 12 education in california from local to state government in the aftermath of the initial serrano decision suits were filed in several other states claiming unconstitutional inequities in the state education system many of these suits were successful between 1973 and 1983 six state supreme courts new jersey 1973 connecticut 1977 washington 1978 west virginia 1979 wyoming 1980 arkansas 1983 found their systems of educational finance unconstitutional similar rulings followed in 1989 in kentucky montana and texas in 1993 in massachusetts and tennessee in 1994 in arizona and in 1997 in new hampshire ohio and vermont a third of the states education finance systems now have been ruled unconstitutional as a result of these rulings and legislative based education reforms in a number of other states education expenditure inequality has been reduced 2 this in turn has left local districts with less latitude in determining spending levels parents in richer districts are expected to be especially frustrated with the limits on spending that accompany equalization changes in state educational finance systems to gain greater equity affected average spending on education in these states the initial research on this issue focused on the california experience where raw expenditure figures reveal the dramatic change in per pupil spending in california since the initial serrano decision in 1971 in academic year ay 1969 1970 per pupil spending in california s public elementary and secondary schools was slightly greater than the national average 106 25 of the national average ranking 14th among all states however by ay 1992 1993 education expenditures in california had fallen to 85 6 of the national average and its rank had dropped to 34th silva and sonstelie 1995 concluded that education spending in california in 1989 1990 was significantly lower than they would have otherwise predicted they attributed about half of the lowered spending to the legislation following serrano ii and the other half to the growth of the student population in california but the california experience of reduced expenditures appears to be atypical manwaring and sheffrin 1997 found spending to be higher in many states as a result of litigation or legislativebased educational finance reform downes and shah 1995 similarly estimated that school finance reform raised spending in some states and lowered spending in other states murray evans and schwab 1998 found state per pupil spending rose with successful state education finance litigation the variation across states in the spending effects of education finance reforms may be due to the source court ordered or legislative and or degree e g weak reform strong reform etc of the reforms in any case there should be greater interest in supplementing what the public schools do or opting out of the public system if reforms cause spending in a state to fall

underlying trends and seasonality in uk energy demand a sectoral analysis this paper demonstrates the importance for energy demand modelling of allowing for trends and seasonal effects that are stochastic in form inherent underlying trends may be non linear and reflect not only technical progress which usually produces greater energy efficiency but also other factors such as changes in consumer tastes and the economic structure that may be working in the opposite direction using quarterly unadjusted data for various sectors in the uk it is shown that unless energy demand models are formulated so as to allow for stochastic trends and seasonals estimates of price and income elasticities could be seriously biased

impact of energy policy instruments on the estimated level of underlying energy efficiency in the eu residential sector the promotion of energy efficiency is seen as one of the top priorities of eu energy policy ec 2010 in order to design and implement effective energy policy instruments it is necessary to have information on energy demand price and income elasticities in addition to sound indicators of energy efficiency this research combines the approaches taken in energy demand modelling and frontier analysis in order to econometrically estimate the level of energy efficiency for the residential sector in the eu 27 member states for the period 1996 to 2009 the estimates for the energy efficiency confirm that the eu residential sector indeed holds a relatively high potential for energy savings from reduced inefficiency therefore despite the common objective to decrease wasteful energy consumption considerable variation in energy efficiency between the eu member states is established furthermore an attempt is made to evaluate the impact of energy efficiency measures undertaken in the eu residential sector by introducing an additional set of variables into the model and the results suggest that financial incentives and energy performance standards play an important role in promoting energy efficiency improvements whereas informative measures do not have a significant impact

measurement of energy efficiency based on economic foundations abstract energy efficiency policy is seen as a very important activity by almost all policy makers in practical energy policy analysis the typical indicator used as a proxy for energy efficiency is energy intensity however this simple indicator is not necessarily an accurate measure given changes in energy intensity are a function of changes in several factors as well as true energy efficiency hence it is difficult to make conclusions for energy policy based upon simple energy intensity measures related to this some published academic papers over the last few years have attempted to use empirical methods to measure the efficient use of energy based on the economic theory of production however these studies do not generally provide a systematic discussion of the theoretical basis nor the possible parametric empirical approaches that are available for estimating the level of energy efficiency the objective of this paper therefore is to sketch out and explain from an economic perspective the theoretical framework as well as the empirical methods for measuring the level of energy efficiency additionally in the second part of the paper some of the empirical studies that have attempted to measure energy efficiency using such an economics approach are summarized and discussed

do energy efficiency policies save energy a new approach based on energy policy indicators in the eu member states abstract over the last two decades the european union and its member states have introduced policies aimed at improving energy efficiency the energy service directives esd introduced the concept of measurement of energy savings attributed to policies two different and complementary methodologies for the evaluation of energy savings have been developed under the esd the bottom up bu approach based on a technical analysis of each measure and the top down td approach based on the analysis of how energy intensity changes over time bu methods can hardly take into account policy induced behavioural changes whereas td methods have difficulties in disentangling policy induced savings from other savings econometric models have been proposed as a viable alternative to deal with both drawbacks the purpose of this article is to present an econometric model aimed at estimating the energy savings induced by energy efficiency policies in the eu member states in the period 1990 2013 we introduce an explicit measure of energy policy intensity based on the mure database which is used as explanatory variable in a dynamic panel model for 29 european countries our results suggest that energy consumption in 2013 in europe would have been about 12 higher in the absence of energy efficiency policies

energy efficiency in swedish industry a firm level data envelopment analysis this paper assesses energy efficiency in swedish industry using unique firm level panel data covering the years 2001 2008 the efficiency estimates are obtained for firms in 14 industrial sectors by using data envelopment analysis dea the analysis accounts for multi output technologies where undesirable outputs are produced alongside with the desirable output the results show that there was potential to improve energy efficiency in all the sectors and relatively large energy inefficiencies existed in small energy use industries in the sample period also we assess how the eu ets the carbon dioxide co2 tax and the energy tax affect energy efficiency by conducting a second stage regression analysis to obtain consistent estimates for the regression model we apply a modified input oriented version of the double bootstrap procedure of simar and wilson 2007 the results of the regression analysis reveal that the eu ets and the co2 tax did not have significant influences on energy efficiency in the sample period however the energy tax had a positive relation with the energy efficiency

estimating the potential for electricity savings in households abstract improving efficiency in the use of energy is an important goal for many nations since end use energy efficiency can help to reduce co 2 emissions furthermore since the residential sector in industrialised countries requires around one third of the end use electricity it is important for policy makers to estimate the scope for electricity saving in households to reduce electricity consumption by using appropriate steering mechanisms we estimate the level of technical efficiency in the use of electricity using data from a swiss household survey we find an average inefficiency in electricity use by swiss households of around 20 to 25 bottom up economic engineering models estimate the potential in switzerland to be around 15 in this paper we use a sub vector input distance frontier function based on economic foundations our estimates lie at the upper end of the electricity saving potential estimated by the afore mentioned economic engineering approach

energy planning and its relationship to energy poverty in decision making a first approach for the canary islands abstract after reviewing the energy policies in the canary islands this study addresses the concept of energy poverty from a different perspective than that usually found in the academic literature this analysis advances knowledge of the role played by the following six pillars sustainability renewable energies energy efficiency self consumption regimes electrification of energy demand and electrical interconnections regarding energy poverty in these isolated environments the relationship of these pillars with energy poverty is analysed in terms of energy scenarios projected for 2030 the results show that the interrelations between these six elements are a good indicator of the evolution of energy poverty they also provide a roadmap for energy policy in these regions this research highlights the importance of promoting energy policies that are not based on short term results and that energy strategy does not necessarily require planning more tasks in a shorter time intending to asses policies suitable for implementation in the medium and long term this study proposes alternative definitions to measure energy poverty by identifying the key pillars in energy planning for the canary islands
