total factor carbon emission performance of the chinese transportation industry a bootstrapped non radial malmquist index analysis this paper proposes a non radial malmquist co2 emission performance index nmcpi for measuring dynamic changes in total factor co2 emission performance over time this index enables the consideration of non radial slacks in the conventional malmquist co2 emission index mcpi the nmcpi is calculated based on a non radial directional distance function derived by several data envelopment analysis dea models furthermore nmcpi could be decomposed into an efficiency change ec index and technological change tc index a bootstrapping approach is conducted to introduce statistical inferences into the nmcpi and its decompositions based on the proposed indices the dynamic co2 emission performance change and its decompositions of the chinese regional transportation industry from 2002 to 2010 are investigated the empirical results demonstrate that the total factor carbon emission performance of the transportation industry as a whole decreased by 32 8 over the period and this reduction was primarily caused by technological decline

the assessment competition policy the paper advances four propositions concerning the objectives content and institutions of competition policy first the role of policy should be to advance economic efficiency rather than competition for its own sake or some wider definition of the public interest second economic analysis is generally ambiguous a priori about the efficiency effects of particular market structures and conduct third the design of policy and institutions needs to reflect this ambiguity policy rules are essential but there should be scope for parties to argue countervailing efficiency benefits a policy institution should be empowered to identify investigate and propose remedies for failures of competition subject to review by an independent competition tribunal fourth international harmonization of competition policies is essential current policies in the u k and ec and relationships between the two are evaluated and the case made for a radical reform of u k policy copyright 1993 by oxford university press

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

an equilibrium efficiency frontier data envelopment analysis approach for evaluating decision making units with fixed sum outputs abstract based on the minimal reduction strategy yang et al 2011 developed a fixed sum output data envelopment analysis fsodea approach to evaluate the performance of decision making units dmus with fixed sum outputs however in terms of such a strategy all dmus compete over fixed sum outputs with no memory that will result in differing efficient frontiers evaluations to address the problem in this study we propose an equilibrium efficiency frontier data envelopment analysis eefdea approach by which all dmus with fixed sum outputs can be evaluated based on a common platform or equilibrium efficient frontier the proposed approach can be divided into two stages stage 1 constructs a common evaluation platform via two strategies an extended minimal adjustment strategy and an equilibrium competition strategy the former ensures that original efficient dmus are still efficient guaranteeing the existence of a common evaluation platform the latter makes all dmus achieve a common equilibrium efficient frontier then based on the common equilibrium efficient frontier stage 2 evaluates all dmus with their original inputs and outputs finally we illustrate the proposed approach by using two numerical examples

a generalized equilibrium efficient frontier data envelopment analysis approach for evaluating dmus with fixed sum outputs the recently published equilibrium efficient frontier data envelopment analysis eefdea approach yang et al 2014 represents a step forward in evaluating decision making units dmus with fixed sum outputs when compared to prior approaches such as fsodea fixed sum outputs dea approach yang et al 2011 and zsg dea zero sum gains dea approach lins et al 2003 and so on based on the eefdea approach in this paper we proposed a generalized equilibrium efficient frontier data envelopment analysis approach geefdea which improves and strengthens the eefdea approach compared to eefdea approach this approach makes several improvements in evaluation namely that 1 it is not necessary to determine the evaluation order in advance which overcomes the limitation that different evaluation orders will lead to different results 2 the equilibrium efficient frontier can be achieved in only one step no matter how many dmus they are which greatly simplifies the procedure to reach the equilibrium efficient frontier especially when the number of dmus is large and 3 the constraint that signs of outputs adjustment of each dmu must be same all non positive or all non negative in prior approaches has been relaxed in this sense the result obtained by the proposed approach is more consistent with the demand of practical applications finally the proposed approach combined with assurance regions ar is applied to the data set of 2012 london olympic games

reputation and imperfect information abstract a common observation in the informal literature of economics and elsewhere is that is multistage games players may seek early in the game to acquire a reputation for being tough or benevolent or something else but this phenomenon is not observed in some formal game theoretic analyses of finite games such as selten s finitely repeated chain store game or in the finitely repeated prisoners dilemma we reexamine selten s model adding to it a small amount of imperfect or incomplete information about players payoffs and we find that this addition is sufficient to give rise to the reputation effect that one intuitively expects

resistance to reform status quo bias in the presence of individual specific uncertainty comment why do governments so often fail to adopt policies which economists consider to be efficiency enhancing our answer to this question relies on uncertainty regarding the distribution of gains and losses from reform we show that there is a bias towards the status quo and hence against efficiency enhancing reforms whenever some of the individual gainers and losers from reform cannot be identified beforehand there are reforms which once adopted will receive adequate political support but would have failed to carry the day ex ante the argument does not rely on risk aversion irrationality or hysteresis due to sunk costs jel d72 f13 why do governments so often fail to adopt policies that economists consider to be efficiency enhancing this is one of the fundamental questions of political economy the answer usually relies on what may be

shareholder protection compulsory acquisition and the efficiency of the takeover process this paper examines public good problems connected with takeovers two broad categories of exclusion device oppression of minority interests and compulsory acquisition of shares are evaluated it is argued that inability to control the level of oppression with any precision renders the first method unsatisfactory from the policy viewpoint but that strong protection of minorities coupled with compulsory acquisition rights for the acquiror can straightforwardly generate an efficient solution to the public good problems it is shown that in the u k company law and the city code on takeovers and mergers combine to produce an approximation to this efficient solution against managements which are performing poorly in the eyes of the capital market and since the work of marris 1964 this incentive mechanism has come to play a prominent role in the economic analysis of company behaviour the usual argument is that as the market value of a particular company falls relative to the level that it is generally believed could be obtained by other managers following different policies the firm becomes increasingly vulnerable to a takeover by a raider attracted by the prospect of the capital gains that would ensue following managerial changes in turn the threat to the incumbent managers acts as a deterrent to behaviour which runs counter to shareholders interests the effectiveness of the workings of the takeover mechanism is therefore of some importance for the efficient utilisation and allocation of resources potential obstacles to the smooth functioning of the takeover process have however been recognised for quite some time as long ago as 1926 the greene committee on company law reform identified cases where a takeover had been inhibited by the actions of small minorities of shareholders much more recently grossman and hart 1980 have formalised some of the earlier points in a way that clearly highlights one of the major difficulties that freeriding strategies on the part of shareholders in firms with dispersed share ownership can prevent successful bids the argument is that shareholders of the target company believing their own actions have a trivially small effect on

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

non parametric productivity analysis with undesirable outputs an application to the canadian pulp and paper industry this article extends the chavas cox approach to non parametric analysis by incorporating undesirable outputs to provide a more complete representation of the production technology inner and outer non parametric technology bounds are constructed the methods are illustrated with application to time series data for the canadian pulp and paper industry conventional measures that ignore changes in pollutant outputs underestimate true productivity growth further there is a large gap between estimates generated with reference to inner and outer bounds to the technology suggesting that researchers need to be aware of the limitations of results derived from analyses relying only on dea methods copyright 2001 oxford university press

measuring the performance of thermal power firms in china via fuzzy enhanced russell measure model with undesirable outputs abstract thermal power has accounted for the major part of the electricity generation over recent several decades in china it plays an important role in supporting china s economic development while it also brings great pressure to the environment protection because of a large amount of pollution generated during its production in order to solve or alleviate the environmental problem caused by thermal power firms efficiency evaluation is the first important step as thermal power firm is a complex system with multiple inputs and multiple outputs usually including fuzzy data and undesirable outputs in the productions in this paper we build an integrated enhanced russell measure model based on data envelopment analysis for evaluating the performance of decision making units in the presence of the undesirable outputs in fuzzy circumstance then this new model is applied to analyze the environmental performance and provide the benchmarks for the thermal power firms in china which can guide the decision makers to make suitable future production plans for improving their performance

green efficiency and environmental subsidy evidence from thermal power firms in china abstract to achieve green development ample environmental subsidies have been invested into many energy intensive firms such as thermal power firms in china investigations of the effects of this kind of subsidy can help to provide specific and important implications for ongoing regulations unlike previous studies on the national regional or sectoral level this paper measures green efficiency and its compositions of thermal power firms and studies the impact of environmental subsidies on green efficiency by using the classical slacks based measure and tobit model the results show that the average green efficiency ranges from 0 509 to 0 663 during 2010 2015 which is much lower than the general efficiency the green scale efficiency is the main reason for the low green efficiency thus indicating large room for improvement environmental subsidies negatively affect green efficiency and its decompositions from 2010 to 2013 the negative effect becomes weak and insignificant in 2014 and the environmental subsidies start to significantly promote green efficiency and its decompositions in 2015 according to our findings some implications relating to improving green scale efficiency increasing the intensity of environmental subsidies to firms and strengthening their supervision are proposed

balanced budget redistribution as the outcome of political competition this paper models balanced budget redistribution between socio economic groups as the outcome of electoral competition between two political parties equilibrium is unique in the present model and a sufficient condition for existence is given requiring that there be enough stochastic heterogeneity with respect to party preferences in the electorate the validity of hotelling s principle of minimum differentiation and of director s law are examined under alternative hypotheses concerning administrative costs of redistributions and voter s possibilities both of abstaining from voting and of becoming campaign activists for one of the parties the policy strategy of expected plurality maximization is contrasted with the strategy of maximizing the probability of gaining a plurality incomes are fixed and known so lump sum taxation is feasible however constraints on tax transfer differentiation between individuals are permitted in the analysis

on the form of transfers to special interests an important question in political economy concerns the form of transfers to special interests the chicago view is that political competition leads politicians to make such transfers efficiently the virginia position is that lack of information on the part of voters leads politicians to favor inefficient sneaky methods of redistribution this paper analyzes the form of transfers in a model of political competition in which politicians have incentives to make transfers to special interests it shows that when voters have imperfect information about both the effects of policy and the predispositions of politicians inefficient methods of redistribution may be employed

redistributive politics and economic efficiency the political process often compensates the losers from technical change or international competition in an economically inefficient way namely by subsidizing or protecting declining industries instead of encouraging the movement of resources to other more productive uses we find that a dynamic inconsistency in the game of redistributive politics contributes to this outcome to achieve economically efficient outcomes it is necessary that those making economically inefficient choices not be given offsetting transfers but the political process distributes income on the basis of political characteristics which are in general different from the economic characteristics that are rewarded by the market we identify circumstances in which the inefficient choosers have desirable political characteristics and are therefore immune from threats of having to face the economic consequences of their choices

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

radial and non radial decompositions of luenberger productivity indicator with an illustrative application abstract viewing slacks as one possible source of inefficiency and that inputs have differential importance in the production process this paper develops based on the directional russell measure of inefficiency the non radial luenberger indicator this indicator is then shown as the sum of the individual input specific luenberger indicators the luenberger indicator and its various input specific indicators are also then shown as the composite measure of efficiency change and technical change this decomposition enables the researcher to empirically examine the contributions of each factor input towards the productivity change and its components efficiency change and technical change our proposed decomposition scheme is then empirically illustrated to analyze the eco productivity performance behavior of the 22 oecd countries during the period 1995 2004 our results indicate that first the productivity change estimates yielded from the non radial luenberger indicator are different from those yielded from its radial counterpart when slacks are present second most of these countries are found experiencing productivity growth due to technical progress alone and finally as regards the order of input specific contributions towards productivity growth capital contributes the most followed by savings in emissions and labor respectively

case study on initial allocation of shanghai carbon emission trading based on shapley value abstract carbon emission trading is an effective measure to reduce greenhouse gas emissions worldwide china has publicized plans to initiate the demonstration of carbon emission trading in seven regions as of 2013 initial allocation is fundamental but it proposes difficulty in the mechanism design of the carbon emission trading system benchmark grandfathering and the shapley value have been employed to simulate a specific case which consists of the initial allocation of carbon emission allowances of three power plants in shanghai china the results of the shapley value are regarded as a theoretical equitable reference the results of benchmark are similar to those of the shapley value however it is apparent that the allocation regarding grandfathering is inequitable considering other factors we proposed the following at the introduction of experimental stage free allocation pertaining to grandfathering can be adopted meanwhile benchmark should be prepared and adopted at the appropriate time furthermore a portion of the initial allowances can be reserved for auction and this portion for auction will escalate to the extent of 100 upon entering the formal stage in addition the tiered price mechanism and the subsidy policy are also suggested

why higher takeover premia protect minority shareholders posttakeover moral hazard by the acquirer and free riding by the target shareholders lead the former to acquire as few sharcs as necessary to gain control as moral hazard is most severe under such low ownership concentration inefficiencies arise in successful takeovers moreover share supply is shown to be upward sloping rules promoting ownership concentration limit both agency costs and the occurrence of takeovers furthermore higher takeover premia induced by competition translate into higher ownership concen tration and are thus beneficial finally one share one vote and simple majority are generally not optimal and socially optimal rules need not emerge through private contracting

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

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

efficiency of a fixed but allocatable input a non parametric approach the traditional non parametric or dea models measure efficiency for given inputs and outputs without allowing for reallocation of inputs these models do not look inside the technology but rather treat it as a black box in this paper we open up the box by modeling the possibility of reallocation of a fixed input

fixed cost and resource allocation based on dea cross efficiency abstract in many managerial applications situations frequently occur when a fixed cost is used in constructing the common platform of an organization and needs to be shared by all related entities or decision making units dmus it is of vital importance to allocate such a cost across dmus where there is competition for resources data envelopment analysis dea has been successfully used in cost and resource allocation problems whether it is a cost or resource allocation issue one needs to consider both the competitive and cooperative situation existing among dmus in addition to maintaining or improving efficiency the current paper uses the cross efficiency concept in dea to approach cost and resource allocation problems because dea cross efficiency uses the concept of peer appraisal it is a very reasonable and appropriate mechanism for allocating a shared resource cost it is shown that our proposed iterative approach is always feasible and ensures that all dmus become efficient after the fixed cost is allocated as an additional input measure the cross efficiency dea based iterative method is further extended into a resource allocation setting to achieve maximization in the aggregated output change by distributing available resources such allocations for fixed costs and resources are more acceptable to the players involved because the allocation results are jointly determined by all dmus rather than a specific one the proposed approaches are demonstrated using an existing data set that has been applied in similar studies

privatization in theory and practice privatization george yarrow this paper examines the theoretical and empirical case for private versus public ownership privatization usually leads managers to place greater emphasis on the pursuit of profits however whether this is beneficial to society depends on the trade off between possible market failures due to a lack of competition and deficiencies in government control of public firms the competitive and regulatory environment is more important than the question of ownership per se in competitive markets there is a presumption in favour of private ownership where there is a natural monopoly vigorous regulatory action is required the evidence suggests that privatization has led to improved performance by firms such as the national freight corporation and cable and wireless which operate in a relatively competitive environment the benefits are less clear in the case of firms like bp britoil and british aerospace however the most worrying case is that of british telecom and the projected privatization of british gas where little thought has been given to limiting the abuse of monopoly power rather the regulatory environment has been tailored to the needs of the existing management and to ensuring a successful share flotation privatization is also advanced as a weapon for reducing trade union power encouraging wider share ownership redistributing wealth and improving the public finances however there are other policy instruments better suited to achieving these objectives the existing privatization programme has not led to a marked widening of share ownership and has resulted in windfall gains to a small group of investors at the expense of taxpayers in general

freeze out mergers do freeze out mergers mitigate the free rider problem of corporate takeovers we study this question in a tender offer model with finitely many shareholders under a freeze out merger minority shareholders expect to receive the original offer price whether or not they tender their shares we show that the ability to freeze out shareholders increases the raider s expected profit however as the number of shareholders gets arbitrarily large the raider s expected profit in equilibrium converges to zero for any freeze out clause with an ownership threshold that is strictly above simple majority in this sense freeze out mergers do not solve the free rider problem received september 17 2016 editorial decision june 3 2018 by editor francesca cornelli

information in tender offers with a large shareholder we study takeovers of firms whose ownership structure is a mixture of minority block holders and small shareholders we show that the combination of dispersed private information on the side of small shareholders and the presence of a large shareholder can facilitate profitable takeovers furthermore our analysis implies that even if some model of takeovers predicts a profit for the raider for example due to private benefits the profit will be underestimated unless the large shareholder and the dispersion of information among the small shareholders are modeled

voting on the budget deficit this paper analyzes a model in which a group of rational individuals votes over the composition and time profile of public spending all voters agree that a balanced budget is ex ante optimal however if there is disagreement between current and future majorities a balanced budget is not a political equilibrium under majority rule under certain conditions a majority of the voters favors a budget deficit and the equilibrium deficit is larger the greater is the polarization among voters copyright 1990 by american economic association

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

competition strategy and efficiency evaluation for decision making units with fixed sum outputs this paper develops a dea data envelopment analysis model to accommodate competition over outputs in the proposed model the total output of all decision making units dmus is fixed and dmus compete with each other to maximize their self rated dea efficiency score in the presence of competition over outputs the best practice frontier deviates from the classical dea frontier we also compute the efficiency scores using the proposed fixed sum output dea fsodea models and discuss the competition strategy selection rule the model is illustrated using a hypothetical data set under the constant returns to scale assumption and medal data from the 2000 sydney olympics under the variable returns to scale assumption

a more scientific allocation scheme of carbon dioxide emissions allowances the case from china abstract efficient allocation of carbon dioxide co2 emissions allowances is essential to the realization of the emissions reduction goal using china as an example this study applies a zero sum gains data envelopment analysis zsg dea model to translate the country s reduction target into provincial goals based on the chinese government s 2020 reduction goal to evaluate efficiency scores we employ the epsilon based measure model that combines radial and non radial characteristics different from prior studies we emphasize the effect of industrial structure on co2 emissions and calculate a composite gross domestic product gdp index as one of the output variables by utilizing the zsg dea model and based on china s provincial co2 emissions allowances as the input variable the composite gdp index and the population as the output variable we obtain an optimal reallocation scheme after four iterations a comparison between the results and official reduction goals shows that the government should increase co2 emissions allowances appropriately for most provinces with high proportions more than 40 of second industry increment in gdp thereby carrying implications for policymakers with china as an example these findings have global implications as regards developing a more scientific allocation scheme especially for regions with unbalanced industrial structures
