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

trade liberalization and wage inequality abstract this paper studies empirically the link between trade liberalization and wage inequality in chile within the context of the heckscher ohlin samuelson hos model we use cointegration techniques to estimate the long run relationship between the skill premium in chile and product prices openness and factor endowments we find that the fall in the relative price of labor intensive goods helps explaining the increase in wage inequality in chile during the last two decades the increase in proportion of the labor force with college degree on the other hand tends to reduce wage inequality in chile openness measured as the volume of trade over gdp widens the wage gap between skilled and unskilled labor we offer some hypothesis on the elements that are behind this positive relationship between wage openness and inequality but no empirical work is done this area may be an interesting subject of research

does marriage really make men more productive this paper presents new descriptive evidence regarding marital pay premiums earned by white males longitudinal data indicate that wages rise after marriage and that cross sectional marriage premiums appear to result from a steepening of the earnings profile data from a company personnelfile that includes information on job grades and supervisor performance ratings reveal large marital status pay differences within a narrow range of occupations managers and professionals and environments a single firm married workers tend to be located in higher paying job grades there are very small pay differentials within grades married men receive higher performance ratings than single men as a result they are much more likely to be promoted controlling for rated performance however eliminates the promotion differential sanders korenman is an assistant professor of economics and public affairs at princeton university and is a faculty associate of the office of population research at princeton university and a research affiliate of the national bureau of economic research nber david neumark is an assistant professor of economics at the university of pennsylvania and a research affiliate of the nber korenman wishes to acknowledge the hewlett foundation and the harvard university center for population studies for financial support the authors are grateful to james medofffor making available an extract from the company personnelfile questions regarding data availability should be directed to professor james

growth and poverty reduction in ethiopia evidence from household panel surveys abstract the paper investigates the impact of growth on poverty in ethiopia by analysing panel data covering 1994 97 a period of economic recovery driven by peace good weather and much improved macroeconomic management the analysis of poverty shows land ownership education type of crops planted occupations in urban areas dependency ratios and location to be important determinants the characteristics of households that fell into or escaped from poverty are examined in addition the profile of those that remained poor during the period the chronic poor is looked at in rural areas the cultivation of a nontraditional export crop chat has significantly improved the welfare of households primary education plays a more important role in improving welfare in urban than in rural areas decomposition of changes in poverty into growth and redistribution components indicates that potential poverty reduction due to the increase in real per capita income was to some extent counteracted by worsening income distribution the implications of the results for a propoor policy are discussed

resource allocation based on efficiency analysis the purpose of this paper is to develop an approach to a resource allocation problem that typically appears in organizations with a centralized decision making environment for example supermarket chains banks and universities the central unit is assumed to be interested in maximizing the total amount of outputs produced by the individual units by allocating available resources to them we will develop an interactive formal approach based on data envelopment analysis dea and multiple objective linear programming molp to find the most preferred allocation plan the units are assumed to be able to modify their production in the current production possibility set within certain assumptions various assumptions are considered concerning returns to scale and the ability of each unit to modify its production plan numerical examples are used to illustrate the approach

some models for estimating technical and scale inefficiencies in data envelopment analysis in management contexts mathematical programming is usually used to evaluate a collection of possible alternative courses of action en route to selecting one which is best in this capacity mathematical programming serves as a planning aid to management data envelopment analysis reverses this role and employs mathematical programming to obtain ex post facto evaluations of the relative efficiency of management accomplishments however they may have been planned or executed mathematical programming is thereby extended for use as a tool for control and evaluation of past accomplishments as well as a tool to aid in planning future activities the ccr ratio form introduced by charnes cooper and rhodes as part of their data envelopment analysis approach comprehends both technical and scale inefficiencies via the optimal value of the ratio form as obtained directly from the data without requiring a priori specification of weights and or explicit delineation of assumed functional forms of relations between inputs and outputs a separation into technical and scale efficiencies is accomplished by the methods developed in this paper without altering the latter conditions for use of dea directly on observational data technical inefficiencies are identified with failures to achieve best possible output levels and or usage of excessive amounts of inputs methods for identifying and correcting the magnitudes of these inefficiencies as supplied in prior work are illustrated in the present paper a new separate variable is introduced which makes it possible to determine whether operations were conducted in regions of increasing constant or decreasing returns to scale in multiple input and multiple output situations the results are discussed and related not only to classical single output economics but also to more modern versions of economics which are identified with contestable market theories

public disclosure private information collection and short term trading abstract this paper examines how public disclosure affects private inforamtion acquisition activity in a market economy we analyze a setting where traders with short term investment horizons are allowed to trade on their private information prior to a public disclosure we demonstrate in this setting that public disclosure stimulates investment in private information acquisition this result is shown to have implications for the magnitude of the pre announcement and announcement price reactions to the disclosure

technical efficiency of economic systems of eu 15 countries based on energy consumption in the present study data envelopment analysis is used to determine the technical efficiency index of eu 15 countries from 1980 to 2008 using cross country comparison technical efficiency index represents the capacity of an economy to produce a higher level of gross domestic product for a given level of total energy input the level of the technical efficiency index is determined from the energy mix fossil fuels non fossil fuels nuclear energy of each country and depends on the maximization level of the production of the gross domestic product of the economic system without waste of energy resources the current study is applied in the case of the eu15 countries its scope is to highlight the differentiations of country classifications before and after the integration of nuclear energy in the energy mix of each country the main result is that the integration of nuclear energy as an additional input in the energy mixture affects negatively the technical efficiency of countries also when an economy achieves a decrease of the energy consumption produced from fossil fuels and a better exploitation of renewable energy sources clearly improves its capacity to produce more output with the given levels of inputs

household specialization and the male marriage wage premium empirical research has consistently shown that married men have substantially higher wages on average than otherwise similar unmarried men one commonly cited hypothesis to explain this pattern is that marriage allows one spouse to specialize in market production and the other to specialize in home production enabling the former usually the husband to acquire more market specific human capital and ultimately earn higher wages the authors test this hypothesis using panel data from the national survey of families and households the data reveal that married men spent virtually the same amount of time on home production as did single men albeit on different types of housework estimates from a fixed effects wage equation indicate that the male marriage wage premium is not substantially affected by controls for home production activities household specialization the authors conclude does not appear to have been responsible for the marriage premium in this sample

predisclosure information firm capitalization and security price behavior around earnings announcements several studies on the relationship between earnings reports and security price behavior provide evidence suggesting that a significant portion of the information revealed through earnings reports is reflected in security prices prior to the report month e g ball and brown 1968 and brown and kennelly 1972 this has been attributed at least partly to the existence of other more timely sources of information which allow market agents to forecast earnings prior to their release the evidence above reflects an average finding across all firms one question of interest is whether there are significant systematic crosssectional differences in the security price reactions to earnings announcements of firms which are associated with specific firm characteristics that lead to differential amounts of predisclosure information this study focuses on firm size capitalization as one such characteristic a firm

urban wages and labor market agglomeration abstract using the 5 public use micro sample of the 1990 u s census we find that observationally equivalent workers in the manufacturing sector earn higher wages when they are in urban labor markets that have a larger share of national or metropolitan employment in their same occupation and industry groups quantitatively the effect is large with an elasticity measured at the means of between 1 2 and 3 6 for these effects we interpret the willingness of firms to pay more for equivalent workers in dense markets as evidence of an agglomeration economy in urban labor

cost based modelling of optimal emission quota allocation abstract given that a fixed national emission reduction target could be achieved by imposing emission quotas among multiple decision making units under administration a novel nonlinear programming approach is proposed in this paper to obtain an optimal emission quota allocation in a least cost way marginal emission abatement cost curves are simulated based on the environmental performance and marginal emission abatement costs measured in a set of parametric directional output distance functions with multi inputs and multi outputs further the proposed model is applied to empirically investigate the optimal carbon emission quota allocation for china s building construction industry among thirty three provinces in three different regions the results indicate that the relatively developed eastern region in china has higher marginal emission abatement cost and can be imposed with more emission quotas while the central and western regions can undertake more emission reduction approximately 74 million rmb can be saved by implementing the optimal emission allocation proposed in this paper as compared to a uniform emission quota allocation the findings are of great theoretical methodological and practical significance for policymakers and social science researchers in terms of climate change mitigation

efficient allocation of co2 emissions in china a zero sum gains data envelopment model abstract the appropriate allocation of co 2 emission quotas can build up a solid foundation for future emissions trading building co 2 emissions allocation mechanism has significant practical implications based on radial zero sum gains data envelopment zsg dea allocation model this paper uses a non radial zsg dea model to allocate co 2 emissions between different chinese provinces unlike previous studies treating co 2 as the input variable we treat co 2 as the undesirable output variable the modified model can better reflect macro production process while earlier relevant models treated co 2 emissions as inputs this paper contributes to the existing resource allocation method and allocates china s provincial co 2 emissions from the view of technical efficiency the results of our paper reveal that 1 between 2006 and 2010 the cumulative optimal amounts of co 2 emissions were higher than the actual amounts in 12 provinces and lower in other 18 provinces 2 several energy abundant provinces such as shanxi and inter mongolia need to take more responsibilities in co 2 emissions reduction 3 after the zsg dea allocation all provinces co 2 emissions are on zsg dea frontier which reflects the overall pareto optimality

large block transactions the speed of response and temporary and permanent stock price effects abstract the paper investigates how quickly prices attain new equilibrium levels after large block transactions and measures the associated temporary and permanent price effects we find that prices adjust within at most three trades with most of the adjustment occurring in the first trade the temporary price effect for seller initiated transactions is related to block size but the temporary price effect observed for buyer initiated transactions is no larger than that observed in 100 share trades most of the price effect associated with block trades is permanent and is related to block size regardless of the initiating party

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

integrated weighting approach to carbon emission quotas an application case of beijing tianjin hebei region abstract the coordinated development of beijing tianjin hebei region has been included in the chinese 12th five year plan as a national strategy accordingly the cooperation of energy saving and environmental protection is an important part at the present stage establishing carbon emission trading market in china is regarded as an effective measure to reduce and control carbon dioxide emission meanwhile it is an important task for government to allocate carbon emission quotas among regions in order to explore the cross provincial carbon trading market mode of china this paper aims to construct a comprehensive index and use the integrated weighting approach to simulate the carbon quota allocation of beijing tianjin hebei region the results show that firstly the indicator of responsibility which is about 0 56 is given relatively more weight among the three indicators by comparison the weights of capacity and potential are 0 13 and 0 30 secondly the provinces with strong economic ability and lower carbon reduction potential may get fewer proportions of carbon emission quotas such as beijing thirdly since undertaking the function transfer and dispersal of beijing and tianjin hebei should have a relatively high carbon emission quotas in the future carbon trading market these results may provide insightful support for decision makers to promote collaborative carbon reduction and allocate carbon quotas in beijing tianjin hebei region of china

undesirable outputs in efficiency valuations abstract efficiency measurement is usually based on the assumption that inputs have to be minimized and outputs have to be maximized in a growing number of applications however undesirable outputs are incorporated into the production model which have to be minimized in this paper various approaches for treating such outputs in the framework of data envelopment analysis dea are discussed and the resulting efficient frontiers are compared new radial measures are introduced which assume that any change of the output level will involve both undesirable and desirable outputs

measuring macroeconomic performance in the oecd a comparison of european and non european countries abstract we study the macroeconomic performance of 19 oecd countries over the period 1970 1990 performance is defined in terms of the ability of a country s macroeconomic managers to provide four services to their citizens a high level of real gdp per capita a low rate of inflation a low rate of unemployment and a favorable trade balance we use linear programming techniques to construct a best practice macroeconomic performance frontier and to measure the performance of each country in each year relative to the frontier we then add two environmental disamenities carbon and nitrogen emissions to the service list and repeat the analysis to see if the performance rankings change throughout the analysis emphasis is placed on a comparison of the performance of 14 european oecd countries with that of five non european oecd countries we find that performance rankings do change and that the relative performance of the european countries declines when the environmental disamenities are added to the service list

pareto improvement through a reallocation of carbon emission quotas abstract this article presents a methodology that discusses a reallocation of carbon emission quotas based on the zsg dea model also introduces the process of solving the zsg dea model in extensive detail and derives theorems 1 and 2 theorem 1 shows the equivalence in competition and the cooperation case while theorem 2 indicates the correlation between quota adjustment and efficiency change through this zsg dea model the determination of carbon emission quotas is no longer subjective and reasonable carbon emission quotas among countries can be obtained the reallocation of carbon emission quotas can not only ensure that all countries have 100 efficiencies but also help all countries gain through pareto improvement the conclusions of this paper are that most developed countries should increase their carbon emission quotas and that most less developed countries need to reduce theirs including the two most populous countries of china and india the reallocation process should be paid by selling the quotas of low efficient countries so that they can obtain funds to support their development while at the same time high efficient countries can produce more due to relaxation of environmental constraints thus achieving global pareto improvement

earnings determination and labour markets gran santiago chile 1978 abstract the purpose of this study is twofold first to ascertain whether or not there are statistical differences in the structure of earnings functions among workers in various sectors of economic activity second to provide a test of the human capital approach in the explanation of earning differentials among wage earners using individual characteristics of full time wage earners in santiago the results show that the structures of earnings functions are not statistically different across sectors of economic activity also the application of a human capital model shows that about 50 percent of the relative dispersion of earnings may be attributed to differences in schooling and experience

changes in earnings inequality and labour market segmentation metropolitan santiago 1969 78 changes in earnings inequality are examined in this article through an eclectic approach allowing for differences in human capital earnings function by labour market segments several findings are of interest the first are the components of earnings inequality changes these being in order of importance changes in the within segments inequality changes in the relative share of the informal sector segment and changes in relative income between segments second these changes are found to be the result of labour market liberalisation policies such as abolition of both minimum wages and labour turnover legislation in the formal sector the promotion of self employed activities in the informal sector and the selective mobility pattern between segments

do corporate global environmental standards create or destroy market value arguments can be made on both sides of the question of whether a stringent global corporate environmental standard represents a competitive asset or liability for multinational enterprises mnes investing in emerging and developing markets analyzing the global environmental standards of a sample of u s based mnes in relation to their stock market performance we find that firms adopting a single stringent global environmental standard have much higher market values as measured by tobin sq than firms defaulting to less stringent or poorly enforced host country standards thus developing countries that use lax environmental regulations to attract foreign direct investment may end up attracting poorer quality and perhaps less competitive firms our results also suggest that externalities are incorporated to a significant extent in firm valuation we discuss plausible reasons for this observation

regional allocation of co2 emissions allowance over provinces in china by 2020 the mitigation efforts of china are increasingly important for meeting global climate target since the rapid economic growth of china has led to an increasing share in the world s total co2 emissions this paper sets out to explore the approach for realizing china s national mitigation targets submitted to the unfccc as part of the copenhagen accord that is to reduce the intensity of co2 emissions per unit of gdp by 40 45 by 2020 as well as reducing the energy intensity and increasing the share of non fossil fuel consumption through regional allocation of emission allowance over china s provinces since the realization of china s mitigation target essentially represents a total amount emission allowance allocation problem an improved zero sum gains data envelopment analysis optimization model which could deal with the constant total amount resources allocation is proposed in this study by utilizing this model and based on several scenarios of china s economic growth co2 emissions and energy consumption a new efficient emission allowance allocation scheme on provincial level for china by 2020 is proposed the allocation results indicate that different provinces have to shoulder different mitigation burdens in terms of emission intensity reduction energy intensity reduction and share of non fossil fuels increase

how can china reach its co2 intensity reduction targets by 2020 a regional allocation based on equity and development in late 2009 the chinese government committed to cut its carbon dioxide emissions per unit of gross domestic product gdp by 40 to 45 of 2005 levels by 2020 this has raised the issue of how to allocate the co2 reduction target regionally to meet the national reduction target to meet this objective the following aspects may be taken into consideration equity principles common but differentiated responsibilities intensity reduction target fulfillment and economic difference and reduction potential among provinces this paper selects per capita gdp accumulated fossil fuel related co2 emissions and energy consumption per unit of industrial added value as indicators for emission reduction capacity responsibility and potential respectively based on these three indicators a comprehensive index is developed and an intensity allocation model constructed as decision makers may have different preferences when allocating the reduction burden we allocate different weights to the indicators analyzing the results using cluster analysis the following aspects may also be considered together with the national regional development strategy to determine how to share the burden the reduction potential of various regions implementation potential of the plans and promotion of a highly efficient low carbon economic development model

econometric estimation of technical and environmental efficiency an application to dutch dairy farms in this article we estimate the technical and environmental efficiency of a panel of dutch dairy farms nitrogen surplus arising from the application of excessive amounts of manure and chemical fertilizer is treated as an environmentally detrimental input a stochastic translog production frontier is specified to estimate the output oriented technical efficiency environmental efficiency is estimated as the input oriented technical efficiency of a single input the nitrogen surplus of each farm the mean output oriented technical efficiency is rather high 0 894 but the mean input oriented environmental efficiency is only 0 441 intensive dairy farms are both technically and environmentally more efficient than extensive farms

work contracts and earnings inequality the case of chile great social inequality has been one of the worrisome features of economic development in latin america this study focuses on chile one of latin america s fastest growing economies with one of the highest levels of income inequality during the 1990s using micro level data from the 1994 and 2000 encuestas de caracterizacion socio economica this article examines the role of work contracts in explaining male and female earnings and earnings inequality among wage and salary workers over the second half of the 1990s the analysis distinguishes between wage and salary work without a work contract referred to as informal work and wage and salary work with a work contract within the latter group the study further differentiates by the type of work contract held such as permanent and a variety of contingent work contracts the findings reveal that the majority of employees in informal and contingent wage and salary work arrangements earned significantly less than their permanent counterparts additiona

canadian jobs and firm size do smaller firms pay less even after controlling for observable workers characteristics and for occupation and industry specific effects a substantial wage differential remains between large and small firms what underlies the remaining wage differential is unclear direct evidence on pension plan coverage and on lay off rates by firm size is inconsistent with the bad working conditions hypothesis the union avoidance hypothesis does not seem to explain an important portion o f the wage differential as suggested by efficiency wage models part of the remaining wage differential may be due to firms heterogeneity similarly perhaps large firms pay higher wages simply partly beca use they employ workers with more unobserved abilities because differen t explanations of the wage differential may lead to different policy implications determining the source of the wage firm size effect is an important question for future research

can the kuznets effect be relied on to induce equalizing growth abstract the use of internationally comparable income data to test kuznet s inverted u hypothesis introduces several econometric problems this study a explains and corrects for these econometric problems b assesses the sensitivity of estimated results to alternative functional specifications and sample variations c provides a more rigorous test for structural change between more and less developed countries in the phasing of the inequality trend and d estimates the time likely to elapse before various of the developing countries reach the turning point the study s findings offer broad support for kuznets s hypothesis but do not support the advocacy of development policies focused exclusively on growth for low income countries growth s equalizing phase cannot be anticipated to set in for half a century

the impact of earnings announcements on the permanent price effects of block trades this study examines the permanent price effects that accompany block trades before and after earnings announcements permanent price effhcts are determined by comparing prices on either side of block trades this price change may be interpreted as a measure of the information asymmetry between privately informed traders and market makers we examine permanent price effects in the period surrounding earnings announcements to test the prediction that anticipated public announcements give rise to private information acquisition permanent price effects of block trades are analogous to bid ask spreads in prices quoted for small trades in testing for information asymmetries confounding effects may occur due to expected increases in price volatility at the time of an earnings release block trade data are less

allocating fixed costs and resources via data envelopment analysis abstract in this paper we show that data envelopment analysis dea can be viewed as maximising the average efficiency of the decision making units dmus in an organisation building upon this we present dea based models for a allocating fixed costs to dmus and b allocating input resources to dmus simultaneous to allocating input resources output targets are also decided for each dmu numeric results are presented for a number of example problems taken from the literature

do men whose wives work really earn less it is common knowledge among empirical labor economists that household status variables can enter significantly in wage equations in particular a substantial marital wage premium for men has been noted recently a series of articles in the management literature has argued that an even larger premium accrues to those married men whose wives do not work for pay single earner husbands our current study arises in response to perceived deficiencies in the conceptual framework and statistical methods used in these studies

allocation of carbon dioxide emission permits with the minimum cost for chinese provinces in big data environment abstract the environmental problem and global warming have drawn many governments attention in order to solve the problem reasonable allocation of carbon dioxide emission cde permits is an important issue because it sets the targets for the decision making units to control the amount of carbon dioxide emission in this paper a new data envelopment analysis approach is proposed to evaluate the efficiency of decision making units in a big data environment and set the carbon dioxide emission permits for each decision making unit with the minimum costs comparing with the previous works on carbon dioxide emission permits allocation we firstly allocate the amount of carbon dioxide emission permits taking account into the cost each decision making unit should take to achieve its target moreover two kinds of linear programming problems are developed under efficiency invariance principle and efficiency changeability principle respectively as the allocation of carbon dioxide emission permits causes the minimum cost the decision making units are more easily to accept the allocation alternative finally our approach is applied to the carbon dioxide emission permits allocation among chinese provinces the results show that the approach can well allocate the cde permits with the minimum cost and also reveal the relationship between the marginal cost of reducing cde permits and the adjustment on them

a generalized dea model for centralized resource allocation abstract in this paper we introduced a new generalized centralized resource allocation model which extends lozano and villa s and asmild et al s models to a more general case in order to uncover the sources of such total input contraction in the generalized centralized resource allocation model we applied the structural efficiency to further decompose it into three components the aggregate technical efficiency the aggregate allocative efficiency and re transferable efficiency components the proposed models are not only flexible enough for the central decision maker to adjust the inputs and outputs to achieve the total input contraction but also identify the sources of such total input contraction thereby giving rise to an important interpretation and understanding of the generalized centralized resource allocation model finally an empirical example is used to illustrate the approach

block trading and information revelation around quarterly earnings announcements the author investigate the empirical importance of information revelation in the pricing of block trades in particular he examine whether block prices are correlated with the unexpected part of firms quarterly earnings for his sample of block trades information revelation does indeed appear to be a significant factor shortly before earnings announcements article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

a new frontier approach to model the eco efficiency in european countries abstract this study aims to evaluate the resource and environment efficiency problem of european countries we specify a new stochastic frontier model where gross domestic product gdp is considered as the desirable output and greenhouse gases ghg emissions as the undesirable output capital labor fossil fuels and renewable energy consumption are regarded as inputs gdp ghg ratio is maximized given the values of the other four variables the study is divided into two distinct periods 2000 2004 and 2005 2011 this division is related to the implementation of the kyoto protocol in 2005 and will allow us to evaluate the difference between the levels of efficiency before and after the establishment of environmental targets since stochastic frontier models are typically ill posed a new maximum entropy approach to assess technical efficiency which combines information from the data envelopment analysis and the structure of composed error from the stochastic frontier approach without requiring distributional assumptions is presented in this work

olympic ranking based on a zero sum gains dea model abstract it is usual to rank the participant countries in the olympic games in accordance with the number of medals they have won an alternative ranking is suggested in this paper this ranking is based on each country s ability to win medals in relation to its available resources this is an efficiency that can be measured with the help of data envelopment analysis dea for which two models exist the traditional dea model that takes into account variable returns to scale and a dea model based on the premise that the sum of the gains is zero constant sum of outputs it is the latter that is developed in this paper

assessment of the environmental efficiency of the electricity mix of the top european economies via data envelopment analysis abstract moving towards a more sustainable energy system is a major goal of modern societies that aim to minimize the dependence on fossil fuels and the associated anthropogenic impacts in this article the combined use of life cycle assessment lca and data envelopment analysis dea is applied to analyse the environmental performance eco efficiency of the electricity mix of the top european economies this approach allows identifying environmentally efficient and inefficient countries considering as undesirable inputs several environmental impacts associated with the production of 1 kwh regarded as output the method provides as well targets for the inefficient countries that if attained would make them efficient our results provide valuable insight for governments and policy makers that aim to satisfy the electricity demand while minimizing the associated environmental impact

is the lithuanian economy approaching the goals of sustainable energy and climate change mitigation evidence from dea based environmental performance index abstract even though lithuania has seen extensive social and political transformations there is still a gap in the literature on environmental performance of lithuanian economy specifically the environmental pressures stemming from economic activities have never been analysed in lines with the principles of production economics this paper therefore aims to estimate the environmental performance index epi for lithuanian economic sectors the paper presents the underlying trends in greenhouse gas emissions in lithuania the environmental performance index is estimated by employing the data envelopment analysis in the spirit of the hicks moorsteen indices the present analysis is based on the data from the world input output database specifically the environmental technology is defined in terms of the value added carbon and nitrous oxide emissions labour capital and energy results of the analysis imply that the analysed economic sectors can be grouped into the four clusters with respect to the mean epi and its rate of growth pulp paper and agricultural sectors fall into the best performing group featuring the highest mean epi and the highest growth rate petroleum production and air transport sectors are those featuring the lowest environmental performance therefore the latter sectors should be given an especial importance when developing strategies for increase in sustainability

market response to financial reports abstract a two date rational expectations model is analyzed at the first date traders can privately acquire a costly signal that provides imperfect information about a public report that will be issued at the second date equilibrium characterizations are provided for the fraction of traders that become informed and the informativeness of the first date price as well as the price change variance and the expected trading volume at the second date comparative statics identify how the above variables are influenced by changes in the information content of the public report and in particular how market phenomena at the public release date are influenced by endogenous prior information acquisition and trading in response to the forthcoming public release

the kuznets process and the inequality development relationship abstract in his classic paper on economic growth and income inequality kuznets discussed the process of population shift from traditional to modern activities as the basis for a theory of distributional change during the course of development in this paper we present a formalization of the kuznets process conduct a general analysis of distributional change under this process and derive the functional forms of and conditions for a turning point in the inequality development relationship for six commonly used indices of inequality the functional form appropriate to each index is then estimated using cross section data on 60 developing and developed countries finally some extensions to the initial formalization of the kuznets process are considered

efficiency and allocation of emission allowances and energy consumption over more sustainable european economies abstract efficient use of energy reduction in fossil fuel dependence and control of co2 emissions are all fundamental to development of a sustainable economy competitiveness in energy use saves imports of oil and gas increases gross domestic product and creates new jobs in the renewable energy and energy efficiency sectors this study identifies the more or less competitive european union member states in terms of sustainable growth using data envelopment analysis dea model and proposes new allocations of country greenhouse gas limits and energy consumption using a zero sum gains dea model the analysis of european countries fills a gap in the existing literature and contributes to the discussion on the 2020 2030 european strategy proposing an efficiency based indicator which measures country performance in terms of economic social and environmental factors gdp represents the economic factor population represents the social factor and emissions final and renewable energy consumption are the environmental factors the numerical results show that the initial allocations are inefficient applying the modelled reallocation the most efficient countries are rewarded by potential increases in emission and energy consumption while the least efficient countries must bring about decreases to achieve full efficiency

a dea approach for estimating the agricultural energy and environmental efficiency of eu countries this study attempts to evaluate the energy and environmental efficiency of the primary sectors of the eu member state countries the evaluation is based on a non radial data envelopment analysis dea model which allows for non proportional adjustments to energy inputs and undesirable outputs and thus it provides different estimations for energy and environmental efficiency scores the 2001 2008 time period was selected for this research one of the most important findings is that countries like germany sweden or austria with strong environmental protection standards appear to be less energy and environmentally efficient compared with countries like denmark belgium spain france or ireland in addition a series of eastern european countries achieve low efficiency scores which can be characterized as expectable due to low technology level being implemented in the primary production process there are also two sub periods for this research the first one 2001 2006 covers the fully coupled with specific cultivations period for subsidy administation and the second 2007 2008 where the new decoupled subsidy scheme was implemented there are significant hints for considerable changes of energy and environmental efficiency after the implementation of the the new cap with the new member states siginificantly differ of both energy and environmental efficiency copmared with the older ones

bringing income distribution in from the cold the title of this presidential address is chosen to highlight the way in which the subject of income distribution has in the past been marginalised for much of this century it has been very much out in the cold there are signs that in the 1990s it is being welcomed back and i shall be referring to recent research but i would like to use this occasion to give further impetus to the re incorporation of income distribution into the main body of economic analysis this abstract was borrowed from another version of this item

a study of allocative efficiency of pm2 5 emission rights based on a zero sum gains data envelopment model abstract it is an urgent task for china to control haze emission in environmental treatment emission right trading is a feasible way to achieve the reduction of pollutant emission on the premise that the total pollutant emission amount is under control and the allocation of initial emission rights based on the target total amount is the key to emission right trading in this paper via the input oriented zsg dea model the inter provincial allocative efficiency of pm2 5 emission rights is investigated under the condition that the target total amount is fixed the results showed that 1 after initial emission rights were allocated in accordance with the zsg dea model pm2 5 emission amounts of all provinces would be in a new common dea frontier so as to realize the overall pareto optimality with a set total amount 2 two factors namely land areas and atmospheric environmental capacities of all provinces were considered in the actual allocation to avoid the homogenization of all evaluated units found in the previous evaluation literature on allocative efficiency thereby making the evaluation results more in line with the actual situations in all provinces such an investigation approach can provide guidance on the allocation of initial emission rights in emission right trading and the research results can offer empirical support for haze reducing work load conducted by central and local governments of china
