cost efficiency and optimal scale of electricity distribution firms in taiwan an application of metafrontier analysis abstract this paper analyzes the cost efficiency and optimal scale of taiwan s electricity distribution industry due to the substantial difference in network density firms may differ widely in production technology we employ the stochastic metafrontier approach to estimate the cost efficiency of 24 distribution units during the period 1997 2002 empirical results find that the average cost efficiency is overestimated using the traditional stochastic frontier model especially for low density regions the average cost efficiency of the high density group is significantly higher than that of the low density group as it benefits from network economies this study also calculates both short term and long term optimal scales of electricity distribution firms lending policy implications for the deregulation of the electricity distribution industry

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

how not to extend models of inequality aversion abstract several authors have made attempts to improve the explanatory power of models of inequality aversion in particular the one by fehr and schmidt 1999 by adding concerns for total surplus or efficiency in this note i point out that these attempts are misguided because they are equivalent to a much simpler change not requiring an additional parameter unless we simultaneously consider games with different numbers of players in the latter case however such an approach yields implausible predictions

some lessons from past experiments and some challenges for the future reading and rereading the other contributors pieces as they evolved during the production of this controversy the question i found myself coming back to most frequently was the issue of how far whatever we may observe in experiments can genuinely inform the way we model economic behaviour or formulate economic policy in the wider world surely or so some sceptics would argue the principles or processes governing the allocation of scarce resources in the world outside the laboratory are so complex that nothing that experimental economists can do on their shoestring budgets is likely to come anywhere close to usefully mimicking that reality one response to such a position is that it misses the point of most experiments which are not attempts to create faithful miniature replicas of parts of the outside world but rather aim to test certain theoretical models or to examine certain institutional constructs which are themselves abstracted from the welter of obfuscating detail out there the argument is that if the economics profession accords high status to these models accepting them for publication in mainstream journals incorporating them into the body of accumulated wisdom being passed on to fresh generations of students and so on then it would seem to be entirely legitimate if not a mandatory requirement of any discipline with pretensions to scientific rigour to try to test these models in an environment appropriate to the task if such a model performs acceptably in the laboratory that may still be no guarantee that it will hold up in a more complex natural environment but that is not in itself an argument against experimental tests of the theory alternatively if the model performs poorly even in an environment constructed to give it a fair trial this may well be grounds for being cautious about its more general viability though it may also happen that the data generated by such experiments can then provide some insights into where any weaknesses may lie and how the theory might usefully be modified or developed most experimenters and many others who do not run experiments themselves find such a defence of experimental methods both plausible and persuasive however much hinges on what counts as an appropriate environment and what constitutes a fair and relevant test in this paper i shall focus on those issues particularly with respect to individual decision making but also in a more cursory manner with some reference to games and market behaviour

structural change in an open economy we study the importance of international trade in structural change our framework has both productivity and trade cost shocks and allows for non unitary income and substitution elasticities we calibrate our model to investigate south korea s structural change between 1971 and 2005 we nd that the shock processes propagated through the model s two main transmission mechanisms non homothetic preferences and the open economy explain virtually all of the evolution of agriculture and services labor shares and the rising part of the hump shape in manufacturing counterfactual exercises show that the role of the open economy is quantitatively important for explaining south korea s structural change

risk perceptions and distributional judgments abstract we examine the role of laboratory questionnaire experiments and recent applied empirical research on attitudes in understanding the relationships between people s perceptions of inequality and their perceptions of risk we consider risk in three interpretations in vacuo in day to day life and in the original position

more is better but fair is fair tipping in dictator and ultimatum games abstract this paper examines allocators willingness to reward and punish their paired recipients recipients only compete in a skill testing contest the outcome of which determines the size of the surplus in the dictator game allocators reward skillful recipients but punish unskillful ones only modestly the punishment effect is mitigated by the belief held by some allocators that effort is the appropriate measure of deservingness the ultimatum game extension reveals offerers ability to adapt to the strategic environment offers to skillful recipients in the ultimatum game however are shown to be motivated by a taste for fairness and not strategic considerations journal of economic literature classification numbers c70 c91 d63

distributional concerns equity or efficiency oriented abstract this paper provides experimental evidence that in binary choice dictator games the majority of participants are efficiency rather than equity oriented even if their own payoff is reduced by the respective choice therefore altruistic and as a consequence reciprocal motives need to be modelled explicitly if we aim to predict behavior in experiments correctly

examining the cost efficiency of chinese hydroelectric companies using a finite mixture model this paper evaluates the operational activities of chinese hydroelectric power companies over the period 2000 2010 using a finite mixture model that controls for unobserved heterogeneity in so doing a stochastic frontier latent class model which allows for the existence of different technologies is adopted to estimate cost frontiers this procedure not only enables us to identify different groups among the hydro power companies analysed but also permits the analysis of their cost efficiency the main result is that three groups are identified in the sample each equipped with different technologies suggesting that distinct business strategies need to be adapted to the characteristics of china s hydro power companies some managerial implications are developed

inequality aversion and efficiency with ordinal and cardinal social preferences an experimental study abstract in this paper we report on a series of free form bargaining experiments in which two players have to distribute four indivisible goods among themselves in one treatment players are informed about the monetary payoffs associated with each bundle of goods in a second treatment only the ordinal ranking of the bundles is given we find that in both cases inequality aversion plays a prominent role in the ordinal treatment individuals apparently use the ranks in the respective preference orderings over bundles of goods as a substitute for the unknown monetary value allocations that distribute the value money or ranks respectively most equally serve as natural reference points for the bargaining processes frequently such equal split allocations are chosen by our subjects even though they are pareto dominated whether a pareto optimal allocation is chosen or not depends on whether or not it is a pareto improvement relative to the equal split reference allocation we find less pareto damaging behavior due to inequality aversion in the ordinal than in the cardinal treatment

urban biased policies and rising income inequality in china since the start of economic reforms in 1978 china has experienced the largest increase in income inequality of all countries for which comparable data are available according to the world bank 1997 china s gini coefficient increased from 28 2 in 1981 to 38 8 in 1995 based on official survey data another study that used internationally standard definitions for incomes estimated china s gini ratio at 38 2 in 1988 and 45 2 in 1995 a level that already surpassed many developing economies in asia azizur khan and carl riskin 1998 are these income inequality changes the consequence of institutional reforms that replaced egalitarian rewards with work incentives employment contracts and labor mobility this paper uses household survey data collected by china s state statistical bureau ssb to investigate the sources and causes of this rising inequality by analyzing gini ratios and generalized entropy measures i decompose the overall inequality into three sectoral components i inequality within rural areas ii inequality within urban areas and iii sectoral disparity the data indicate that increases in rural urban income differentials have been the driving factor behind the rising overall inequality in china i argue that urbanbiased policies and institutions including labor mobility restrictions welfare systems and financial policies of inflation subsidies and investment credits to the urban sector are responsible for the long term rural urban divide and the recent increases in disparity

does payoff equity facilitate coordination a test of schelling s conjecture abstract starting from schelling 1960 several game theorists have conjectured that payoff equity might facilitate coordination in normal form games with multiple equilibria the more equitable equilibrium might be selected either because fairness makes it focal or because many individuals dislike payoff inequities as abundant experimental evidence suggests in this line we propose a selection principle called equity eq which selects the equilibrium in pure strategies minimizing the difference between the highest and smallest money payoff if only one such equilibrium exists using a within subjects experimental design furthermore we study the relative performance of eq in twelve simple 2 2 coordination games in many of these games we find that eq explains individual behavior better than a large range of alternative theories including theories of bounded rationality and several other equilibrium selection principles yet we also observe that the frequency of eq play depends on the payoff structure of the game for instance eq play diminishes when the alternative equilibrium is socially efficient and not very unfair compared with the eq equilibrium our data suggests that equilibrium selection is affected by several factors and that subjects are heterogeneous in this respect but also that equity is often a crucial factor to understand coordination

fairness versus efficiency abstract fairness is a strong concern as shown by dictator and ultimatum experiments efficiency measured by the sum of individual payoffs is a potentially competing concern in games such as the prisoners dilemma in our experiment the participants can increase efficiency by giving gifts in the one sided treatment this is only possible for one of the two partners the two sided treatment allows for mutual gift giving in both cases decisions can be conditioned on whether there is or there is not an efficiency gain by gift giving our results indicate that efficiency concerns are dominated by fairness concerns that are less stringent in mutual exchanges than in one sided gift relationships

measuring attitudes towards inequality individuals attitudes to inequality aversion are measured using survey data based on the leaky bucket experiment for several groups of students in australia and israel three forms of social welfare function are estimated it is found that measures of inequality aversion can be obtained with some precision and that these estimates are substantially lower than the values typically used by those measuring inequality and examining optimal tax structures furthermore a welfare function based on the gini inequality measure is generally found to give a better fit than forms based on constant relative or constant absolute inequality aversion jel classification c91 d63

a note on the estimation of the equity efficiency trade off for qalys abstract in this note the veil of ignorance approach is tested as a basis for empirically determining the shape of the social welfare function for qalys an experiment is carried out where the participants choose between different societies that differ with respect to per capita qalys and the distribution of qalys the answers are analyzed using logistic regression analysis according to the results the respondents are willing to give up 1 qaly in the group with more qalys to gain 0 45 qalys in the group with fewer qalys but this trade off is independent of the size of the difference in qalys between the groups

are women more risk averse we find that single women exhibit relatively more risk aversion in financial decision making than single men using u s sample data we examine household holdings of risky assets to determine whether there are gender differences in financial risk taking as wealth increases the proportion of wealth held as risky assets is estimated to increase by a smaller amount for single women than for single men gender differences in financial risk taking are also influenced by age race and number of children greater financial risk aversion may provide an explanation for women s lower levels of wealth compared with men s jel j16 d81 g11

efficiency analysis of hydroelectric generating plants a case study for portugal abstract this paper estimates changes in total productivity breaking this down into technically efficient change and technological change by means of data envelopment analysis dea applied to the hydroelectric energy generating plants of edp the portugal electricity company the aim of this procedure is to seek out those best practices that will lead to improved performance in the energy market we rank the plants according to their change in total productivity for the period 2001 2004 concluding that some plants experienced productivity growth while others experienced a decrease in productivity the implications arising from the study are that edp should adopt an internal benchmark management procedure in order to evaluate the relative position of each hydroelectric generating plant and to adopt managerial strategies designed to catch up with the frontier of best practices as the frontier is shifting along the time constant efforts are needed in this respect along the time

project evaluation with democratic decision making what does cost benefit analysis really measure abstract it is often argued that projects involving public good changes should be chosen on the basis of monetary valuation and cost benefit analysis cba however cba is not value free when used to measure welfare it is based on highly controversial value judgements when used to measure efficiency it is based on assumptions of limited relevance to democratic decision making processes cba measures total net willingness to pay neither more nor less while interesting in its own right the normative significance of this indicator is not obvious

economic growth inequality and well being in advanced industrial societies rising levels of inequality have contributed strongly to the observed gap that has emerged between per capita income and the index of sustainable economic welfare isew which in its current versions is known as the genuine progress indicator gpi yet the isew gpi approach to measuring the social costs of inequality has been criticized as ad hoc the present paper reviews the literature on this topic and efforts to resolve it based on the construction of indicators grounded in a a classical utilitarian ethical framework and b empirical evidence on the relationship between income and well being in the united states after tax income per capita grew at an annual rate of 1 7 between 1979 and 2011 a growth rate of 1 2 per year arises when income is adjusted to account for the social costs of inequality the most common adjustment used in isew gpi studies yields a similar growth rate despite much smaller subtractions from baseline income

risk versus social preferences under the veil of ignorance abstract this paper reports experimental evidence from dictator game experiments in which subjects choose repeatedly one out of four options involving a pair of monetary prizes one for them one for another anonymously matched participant in some sessions there is no uncertainty about the player position i e the identity of the best paid agent constant across all options in other sessions subjects choose under the veil of ignorance not knowing in advance to which player position they will be eventually assigned but only that either possibility is equally likely finally we also collect evidence from additional sessions in which the same options correspond to binary lotteries in which subjects may win the high or the low prize with equal probability but their decisions do not affect other participants we frame subjects decisions within the realm of a simple mean variance utility maximization problem in which the parameter associated to the variance is interpreted depending on the treatment as a measure of pure risk aversion pure inequality aversion or some combination of the two our estimates suggest that we can simply rely on risk aversion to explain subjects behavior under the veil of ignorance

cooperation among strangers with limited information about reputation abstract the amount of institutional intervention necessary to secure efficiency enhancing cooperation in markets and organizations in circumstances where interactions take place among essentially strangers depends critically on the amount of information informal reputation mechanisms need transmit models based on subgame perfection find that the information necessary to support cooperation is recursive in nature and thus information generating and processing requirements are quite demanding models that do not rely on subgame perfection on the other hand suggest that the information demands may be quite modest the experiment we present indicates that even without any reputation information there is a non negligible amount of cooperation that is however quite sensitive to the cooperation costs for high costs providing information about a partner s immediate past action increases cooperation recursive information about the partners previous partners reputation further promotes cooperation regardless of the cooperation costs

a literature study for dea applied to energy and environment abstract this study systematically summarizes previous research efforts on data envelopment analysis dea applied to energy and environment in the past four decades including concepts and methodologies on dea environmental assessment industrial developments are very important for all nations in terms of their economic prosperities a problem is that the development produces various pollutions on air water and other types of contaminations all of which are usually associated with our health problems and climate changes thus it is necessary for us to consider how to make a balance between economic success and pollution mitigation to maintain a high level of social sustainability in the world it is widely considered that dea is one of the methodologies to examine the level of sustainability this study examines a recent research trend on dea applications from 1980s to 2010s nowadays many researchers have paid serious attention on how to combat various difficulties in the areas of energy and environment as a result the number of articles on dea applications on energy and environment has dramatically increased particularly after 2000s however it is true that dea has strengths and drawbacks in the applications therefore it is very important for us to carefully use dea for guiding large policy issues and business strategies such as the global warming and climate change an underlying premise of this study is that technology innovation in engineering and natural science may solve various problems by linking it with political and managerial efforts the use of dea provides a methodological linkage among them so enhancing the practicality in mitigating problems due to climate change and environmental pollutions this literature study along with a summary on conceptual and methodological developments provides us with guidelines for our future research works on dea on energy and environment issues

the role of trade in structural transformation abstract low agriculture productivity is considered a key obstacle to economic development for many countries international trade in agricultural goods can help overcome this barrier and facilitate structural transformation because it allows countries to import part of their food needs this article quantifies the role of trade in this context through the examples of south korea during the last 50 years and great britain in the 19th century to do the analysis i calibrate and simulate a two sector neoclassical growth model to match the data and perform the policy experiments i find that agricultural imports played a crucial role in the early transformation of great britain while in south korea trade also had a positive impact on its structural transformation but it could have played a much larger role if the country had not introduced agricultural protection policies

inequality aversion versus risk aversion inequality aversion and risk aversion are widely assumed in economic models however existing economic literature fails to distinguish between the two this paper presents methodology and a laboratory experiment which separates inequality aversion from risk aversion in a set of laboratory experiments subjects had to choose between two risky alternatives which pay meaningful prizes with the same individual risk but different levels of egalitarianism thus the choice of the more egalitarian alternative implies a higher level of inequality aversion the experiment was conducted among children some of whom live on a communal system kibbutz and some in the city

a metafrontier approach for measuring an environmentally sensitive productivity growth index this paper presents an alternative environmentally sensitive productivity growth index to incorporate group heterogeneities into a conventional malmquist luenberger productivity growth index the p

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

environmentally sensitive productivity growth a global analysis using malmquist luenberger index abstract we examine conventional and environmentally sensitive total factor productivity tfp in 41 developed and developing countries over the period of 1971 to 1992 due to the non availability of reliable input and co 2 emissions price data the study uses directional distance function to derive malmquist luenberger ml productivity index the index allows us to decompose the tfp into measures of technical and efficiency changes dea is used to compute the directional distance functions we find that tfp index value is not different when we account for the co 2 emissions relative to the situation when they are freely disposable but for the components of tfp change technical and efficiency changes the null hypothesis of whether the indexes are the same under two different scenarios cannot be accepted issues of catch up and convergence or in some cases possible divergence in productivity are examined within a global framework the paper also studies the impact of openness on conventional and environmentally sensitive measures of productivity

evolution of cooperation in asymmetric commons dilemmas abstract field experiments with asymmetric commons dilemmas have shown that groups who are able to derive high social efficiency also had higher equity compared to groups who were not able to derive significant levels of social efficiency these findings resemble the high productivity in long lasting irrigation systems based on self governance we present an agent based model based on cultural group selection that shows that the patterns observed in the field experiments can be evolved in cases where agents participate regularly in less challenging symmetric public good dilemmas these results indicate that cooperation in asymmetric dilemmas can evolve and persist when the agents contend with other social dilemmas than the asymmetric dilemmas

population consumption and resources ethical issues abstract this article is about the concept of optimum population and consumption even though it is primarily concerned with foundational issues the various ideas that have been discussed in the literature are tested in the context of economic models with limited resources it is argued that broadly speaking existing theories of optimum population and consumption are variants of average and what is often termed classical utilitarianism respectively both classes of theories are shown to have deficiencies in great measure because of their reliance on a defective concept of personhood it is also argued that contractual theories are of little use because potential people as opposed to future people cannot be parties to any contract a generation relative ethics is developed and is put to work in an overlapping generations model it is shown that generation relative ethics even when it is a variant of classical utilitarianism can prescribe a considerably lower population than classical utilitarianism

technical efficiency shadow price of carbon dioxide emissions and substitutability for energy in the chinese manufacturing industries abstract china is the world s largest co 2 producer and energy consumer in this paper we calculate the maximum technically obtainable co 2 emissions reduction from the efficient use of inputs and estimate the shadow prices of co 2 emissions in order to assess the potential cost savings deriving from trading emissions among industries by measuring the input distance function for 30 chinese manufacturing industries our empirical results indicate that co 2 emissions could be reduced by as much as 680 million tons in the aggregate the shadow prices of co 2 vary from a high of 18 82 to a low of zero across industries with an average of 3 13 per ton additionally the estimated indirect morishima elasticities of substitution of capital for fossil fuels indicate that the substitutabilities of capital for oil gas and coal are higher than the substitutability for labor

why is automobile insurance in philadelphia so damn expensive the authors document and attempt to explain the observation that automobile insurance premiums vary dramatically across cities the authors argue that high premiums can be attributed at least in part to large numbers of uninsured motorists in some markets while uninsured motorists can be attributed to high premiums the authors construct a simple noncooperative equilibrium model that can generate inefficient equilibria with uninsured drivers and high yet actuarially fair premiums for certain parameterizations an efficient full insurance equilibrium and inefficient high price equilibria with uninsured drivers exist simultaneously helping to explain price variability across otherwise similar cities policy implications are discussed

social motives in intergroup conflict group identity and perceived target of threat we experimentally test the social motives behind individual participation in intergroup conflict by manipulating the perceived target of threat groups or individuals and the symmetry of conflict we find that behavior in conflict depends on whether one is harmed by actions perpetrated by the out group but not on one s own influence on the outcome of the out group the perceived target of threat dramatically alters decisions to participate in conflict when people perceive their group to be under threat they are mobilized to do what is good for the group and contribute to the conflict on the other hand if people perceive to be personally under threat they are driven to do what is good for themselves and withhold their contribution the first phenomenon is attributed to group identity possibly combined with a concern for social welfare the second phenomenon is attributed to a novel victim effect another social motive reciprocity is ruled out by the data

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

do people care about future generations derived preferences from happiness data the main approaches for computing very long term discount rates revealed and stated preferences have limitations we overcome previous shortcomings using derived preferences i e we retrieve information on very long term time preferences from happiness data and people s expectations about the living conditions of future generations we account for possible endogeneity between expectations about the future and current well being using 2sls we find that negative positive expectations about future generations have a very large negative positive impact on subjective well being this finding suggests that the very long term discount rate is lower than implied by most traditional economic analyses

a continuous state space approach to convergence by parts abstract using a continuous state space approach this note extends feyrer s feyrer j 2003 convergence by parts manuscript dartmouth college available at http www dartmouth edu jfeyrer parts pdf study of the proximate determinants of the shape of the long run distribution of income per capita contrary to feyrer s finding of the primacy of total factor productivity tfp the results here imply that traps in both tfp growth and capital accumulation may matter

the role of the structural transformation in aggregate productivity we investigate the role of sectoral differences in labor productivity in explaining the process of structural transformation the secular reallocation of labor across sectors and the time path of aggregate productivity across countries using a simple model of the structural transformation that is calibrated to the growth experience of the united states we measure sectoral labor productivity differences across countries productivity differences between rich and poor countries are large in agriculture and services and smaller in manufacturing moreover over time productivity gaps have been substantially reduced in agriculture and industry but not nearly as much in services in the model these sectoral productivity patterns generate implications that are broadly consistent with the cross country evidence on the structural transformation aggregate productivity paths and relative prices we show that productivity catch up in industry explains about 50 percent of the gains in aggregate productivity across countries while low relative productivity in services and the lack of catch up explains all the experiences of slowdown stagnation and decline observed across countries

are people inequality averse or just risk averse individuals preferences for risk and inequality are measured through choices between imagined societies and lotteries the median relative risk aversion which is often seen to reflect social inequality aversion is between 2 and 3 most people are also found to be individually inequality averse reflecting a willingness to pay for living in a more equal society left wing voters and women are both more risk and inequality averse than others the model allows for non monotonic swfs implying that welfare may decrease with an individual s income at high income levels which is illustrated in simulations based on the empirical results

regulatory reforms and productivity an empirical analysis of the japanese electricity industry the japanese electricity industry has experienced regulatory reforms since the mid 1990s this article measures productivity in japan s steam power generation sector and examines the effect of reforms on the productivity of this industry over the period 1978 2003 we estimate the luenberger productivity indicator which is a generalization of the commonly used malmquist productivity index using a data envelopment analysis approach factors associated with productivity change are investigated through dynamic generalized method of moments gmm estimation of panel data our empirical analysis shows that the regulatory reforms have contributed to productivity growth in the steam power generation sector in japan

the depressing effect of agricultural institutions on the prewar japanese economy why didn t the japanese miracle take place before world war ii the culprit we identify is a barrier that kept prewar agricultural employment constant using a standard neoclassical two sector growth model we show that the barrier induced sectoral distortion and an ensuring lack of capital accumulation account well for the depressed output level without the barrier japan s prewar gnp per worker would have been at least about a half of that of the united states not about a third as in the data the labor barrier existed because we argue the prewar patriarchy forced the son designated as heir to stay in agriculture

testing beliefs about social preferences evidence from an experimental coordination game we report experimental results on a simple coordination game in which two players can coordinate either on an equal distribution of payoffs or on a pareto superior but unequal distribution of payoffs we find that the higher the difference in individual payoffs the less likely is a successful coordination on the pareto superior distribution while this is well in line with the recent models of inequity aversion our results are best explained not by a preference for equality per se but rather by the belief that the opponent has such a preference

is more always better a survey on positional concerns abstract we use survey data to provide some empirical information about concerns regarding relative standing respondents chose between a world where they have more of a good than others and one where everyone s endowment of the good is higher but the respondent has less than others questions asked about education attractiveness and intelligence for one s child and oneself income vacation time approval and disapproval from a supervisor and papers to write half of the respondents preferred to have 50 less real income but high relative income concerns about position were strongest for attractiveness and supervisor s praise and weakest for vacation time

efficiency based rank assessment for electric power industry a combined use of data envelopment analysis dea and dea discriminant analysis da abstract this study discusses a combined use of dea data environment analysis and dea da discriminant analysis to determine the efficiency based rank of energy firms this type of performance evaluation is important because we often have a difficulty in accessing a large sample on energy firms to derive reliable empirical results the proposed approach is useful in dealing with such a limited number of energy firms often found in previous dea studies on energy industries in the world the proposed approach uses dea to classify energy firms into efficient and inefficient groups based upon their efficiency scores then it utilizes dea da to assess their efficiency scores and ranks in this stage we can find an adjusted efficiency score for each energy firm the proposed approach provides us with the following analytical capabilities all of which cannot be found in a conventional use of dea in assessing energy firms first the proposed dea approach can avoid zero in all multipliers on efficient energy firms by incorporating scsc strong complementary slackness condition so that it can handle an occurrence of multiple reference sets and multiple projections the dea result classifies all energy firms into efficient and inefficient groups second dea da applied to the two groups evaluates all energy firms by an industry wide evaluation not depending upon a limited number of efficient energy firms in a reference set as found in a conventional use of dea the analytical capability can reduce the number of efficient energy firms third the proposed approach can provide their efficiency based ranking scores finally we can conduct a rank sum test based upon their ranking scores to obtain a statistical inference as an application this study uses the proposed approach to examine the performance of japanese electric power industry we find two economic implications one of the two implications is that no major change has occurred in the operational performance of japanese electric power industry because of japanese sluggish economy from 2005 to 2009 the other implication indicates that there are strategic differences in the operation of japanese electric power firms after the liberalization

monotonicity dominance and the pareto principle abstract we examine the implications of three similar criteria that are commonly used in welfare economics and the analysis of inequality and poverty income dominance monotonicity and the pareto principle within the context of income distribution comparisons we show that whilst there is a simple logical relationship between the first two criteria the third is neither implied by nor implies the other two unless an assumption of individual indifference to income distribution is made similar problems arise with a fourth criterion utility dominance that is a natural counterpart to income dominance

productivity growth and pollution in state manufacturing the directional output distance function chambers chung fare 1996 is used to construct a malmquist luenberger index of total factor productivity growth for manufacturing when both good and bad outputs are jointly produced the index is constructed using information on good and bad output quantities and input quantities circumventing the problem of recovering shadow price information for the bad output needed for the fisher or tornqvist type of productivity indices accounting for toxic releases in manufacturing productivity growth averages 1 4 an nually during 1988 1994 the findings also suggest that the failure to account for toxic releases in manufacturing results in a significant under statement of total factor productivity growth

social mobility and the demand for redistribution the poum hypothesis this paper examines the often stated idea that the poor do not support high levels of redistribution because of the hope that they or their offspring may make it up the income ladder this prospect of upward mobility poum hypothesis is shown to be fully compatible with rational expectations and fundamentally linked to concavity in the mobility process a steady state majority could even be simultaneously poorer than average in terms of current income and richer than average in terms of expected future incomes a e rst empirical assessment suggests on the other hand that in recent u s data the poum effect is probably dominated by the demand for social insurance in the future everyone will be world famous for e fteen minutes andy warhol 1968

efficiency productivity and environmental policy a case study of power generation in the eu this study uses the eu public power generating sector as a case study to investigate the environmental efficiency and productivity enhancing performance of the european union s co2 emissions trading scheme eu ets in its first phase using data envelopment analysis methods we measure the environmental efficiency and the productivity growth registered in public power generation across the eu over the 1996 2007 period in the second stage of our analysis we attempt to explain changes in productivity and efficiency over time using econometric techniques our analysis suggests two conclusions carbon pricing led to an increase in environmental efficiency and to a shift outwards of the technological frontier and the overly generous allocation of emission permits had a negative impact on both measures these results are shown to be robust to changes in controls and specifications

non parametric efficiency progress and regress measures for panel data methodological aspects this purely methodological paper deals with the role of time in non parametric efficiency analysis using both fdh and dea technologies it first shows how each observation in a panel can be characterized in efficiency terms vis a vis three different kinds of frontiers i contemporaneous ii sequential and iii intertemporal these are then compared with window analysis next frontier shifts outward and inward interpreted as progress or regress are considered for the two kinds of technologies and computational methods are described in detail for evaluating such shifts in either case these are also contrasted with what is measured by the malmquist productivity index finally an alternative way of identifying progress and regress independent of the frontier notion and referring instead to some benchmark notion is extended here to panel data

prioritarianism and climate change prioritarianism is the ethical view that gives greater weight to well being changes affecting individuals at lower well being levels this view is influential both in moral philosophy and in theoretical work on social choice where it is captured by a social welfare function swf summing a concave transformation of individual well being numbers however prioritarianism has largely been ignored by scholarship on climate change this article compares utilitarianism and prioritarianism as frameworks for evaluating climate policy it reviews the distinctive normative choices that are required for the prioritarian approach specifying a ratio scale for well being if the prioritarian swf takes the standard atkinson form determining the degree of concavity of the transformation function i e the degree of social inequality aversion and choosing between ex ante and ex post prioritarianism under conditions of risk the article also sketches some of salient implications of a prioritarian swf for climate policy with respect to the social cost of carbon the social discount rate optimal mitigation and the dismal theorem finally it discusses the issue of variable population

the effect of power imbalances on incentives to make non contractible investments we use an experiment to study the effect of ex post sharing rules on relationship specific investments in an incomplete contracting context we find that no power structure can induce first best investments and that equally productive partners reach more efficient outcomes with a balanced power structure i e equal sharing of returns than with an asymmetric one in addition we find evidence for behavioural effects partners make higher investments and reach higher efficiency levels than own payoff maximisation would suggest this behaviour is in line with a model where decision makers care about social efficiency it is not consistent with inequity averse preferences

measuring future grandparents preferences for equality and relative standing individuals aversion to risk and inequality and their concern for relative standing are measured through experimental choices between hypothetical societies it is found that on average individuals are both fairly inequality averse and have a strong concern for relative income the results are used to illustrate welfare consequences based on a utilitarian swf and a modified crra utility function it is shown that the social marginal utility of income may then become negative even at income levels that are far from extreme

carbon emission reduction potentials under different polices in chinese cities a scenario based analysis abstract city is the core for carbon emission reduction this paper examines co 2 emission efficiency and productivity in 286 chinese cities under different production scenarios using a non radial directional distance function approach the examination is conducted via three scenarios namely co 2 emission reduction er emission reduction and energy conservation erec and emission reduction energy conservation and economic growth ereceg the results show substantial differences in total factor emission efficiency and productivity across the three scenarios we also found that total factor emission efficiency varies considerably across regional and different sized city groups however the distribution dynamics analysis provides strong evidence for the convergence of total factor emission efficiency across chinese cities in the long run efficiency change contributes of the majority of cross city variation in productivity growth for the sample period however low average total factor emission efficiency and large disparity in emission efficiency indicate great potential for future co 2 reduction regional development programs tend to drive economic activities into low co 2 emission performance regions our empirical findings provide valuable policy implications for achieving the joint targets of economic growth and co 2 emission reduction

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

metafroniter energy efficiency with co2 emissions and its convergence analysis for china this paper measures the energy efficiency performance with carbon dioxide co2 emissions in 30 provinces in china during the period of 1997 2011 using a meta frontier framework with the improved directional distance function ddf we construct a new environmental production possibility set by combining the super efficiency and sequential data envelopment analysis dea models to avoid discriminating power problem and technical regress when evaluating efficiency by ddf then it is used in a meta frontier framework to reflect the technology heterogeneities across east central and west china the results indicate that eastern china achieved the highest progress inefficiency relative to the metafrontier followed by western and the central china by focusing on technology gaps we offer some suggestions for the different groups based on group frontier and meta frontier analyses the inefficiency can be attributed to managerial failure for eastern and western china and technological differences for central china the convergence analysis shows that energy and co2 emission governance will produce negative effects on economic growth and it is suitable and acceptable to introduce rigorous environmental measures in eastern china

inequality aversion in income health and income related health abstract based on a survey of a sample of the general public we estimate inequality aversion across income health and bivariate income health inequality aversion is domain specific mean inequality aversion is greater for income than for health but the underlying distributions of aversion attitudes differ with a highly bi modal distribution of inequality aversion values for health in which nearly half the participants display very low aversion and nearly half display very high aversion aversion to income related health inequality is greater than that to income or health alone consistent with previous literature we find only weak associations between aversion attitudes and individual characteristics the magnitude of the estimates implies potentially large gains in welfare from reducing inequality in these domains

consumer inequality aversion and risk preferences in community supported agriculture abstract in community supported agriculture csa consumers face a tradeoff between i the desire to support a csa farmer and obtain environmentally friendly goods and ii the risk associated with a long term commitment we elicit inequality aversion and risk preferences of a sample of 162 french csa consumers using incentivized field experiments we find that csa consumers are concerned about payoff inequalities while we obtain evidence of advantageous inequality aversion toward csa farmers we also find disadvantageous inequality seeking we find that csa consumers are risk averse and loss averse and distort probabilities we also observe that inequality and risk preferences in the loss domain might complement each other to strengthen consumers support for csa farmers

an experimental test of the concentration index the concentration index is widely used to measure income related inequality in health no insight exists however whether the concentration index connects with people s preferences about distributions of income and health and whether a reduction in the concentration index reflects an increase in social welfare we explored this question by testing the central assumption underlying the concentration index and found that it was systematically violated we also tested the validity of alternative health inequality measures that have been proposed in the literature our data showed that decreases in the spread of income and health were considered socially desirable but decreases in the correlation between income and health not necessarily support for a condition implying that the inequality in the distribution of income and in the distribution of health can be considered separately was mixed

structural change in an interdependent world a global view of manufacturing decline this paper presents a simple model of the world economy in which productivity gains in manufacturing are responsible for the global trend of manufacturing decline and yet in a cross section of countries faster productivity gains in manufacturing do not necessarily imply faster declines in manufacturing in doing so it aims to draw attention to the common pitfall of using the cross country evidence to test a closed economy model and argues for a global perspective in order to understand cross country patterns of structural change one needs a world economy model in which the interdependence across countries is explicitly spelled out jel f43 o11 o14 o19

natural disasters and the effect of trade on income a new panel iv approach natural disasters affect bilateral trade we use this fact to generalize the instrumental variables strategy of frankel and romer 1999 to a panel setup this allows revisiting an old question does openness cause per capita gdp we work with a modified gravity framework in which we interact foreign natural disasters with geography predicting the exogenous component of bilateral trade flows and aggregating over trade partners we obtain a time varying instrument for multilateral openness of a country controlling for constant determinants of income history geography by means of fixed effects we find a robust positive effect of trade on income averaging 0 74 the estimated elasticity is substantially smaller than the one obtained in the cross section poor or non oecd countries feature a larger elasticity

examining risk preferences under high monetary incentives experimental evidence from the people s republic of china several experimental sessions were conducted to elicit certainty equivalents for a sequence of lotteries involving real monetary outcomes the opportunity to conduct sessions in the people s republic of china afforded the ability to offer very large monetary incentives relative to subjects living costs in the highest payoff condition subjects earned three times their normal monthly revenue in the course of a two hour experiment results indicate a statistically significant impact of the level of monetary incentives on revealed risk preferences however even under extreme monetary incentives subjects demanded amounts well in excess of expected value for low probability gain prospects copyright 1992 by american economic association

measuring total factor co2 emission performance and technology gaps using a non radial directional distance function a modified approach implementing the common but differentiated responsibilities principle for co2 mitigation requires an understanding of co2 emission performance and technology gaps in different countries this paper uses a meta frontier and non radial directional distance function to propose an alternative three stage approach to measure total factor co2 emission performance and technology gaps the first stage calculates the co2 emission performance of the group frontier the second stage uses these results to calculate the technology gap ratio the third stage integrates data from the first two stages to calculate co2 emission performance under the meta frontier this approach is easier to apply than other approaches in the literature and effectively avoids the phenomenon of the technology gap ratio being greater than unity the proposed approach can also decompose co2 emission performance loss into two categories management inefficiency and technical gaps to demonstrate the method an empirical analysis using data for 54 countries was conducted the study highlighted three main findings first upper middle income countries did not perform as well as high income countries and lower middle income countries second high income countries generally enjoy optimized production technology whereas the lower middle income countries generally had the lowest technological levels third both management inefficiency and technical gaps negatively impacted co2 emission performance but management inefficiency played a dominant role

would the right social preference model please stand up abstract a number of competing social preference models have been developed inspired by the evidence from economic experiments we test the relative performance of some of these models using an experimental design that is aimed at capturing pure distributional concerns in a multi person setting we find that the individuals in this study are heterogeneous and that they do not follow any single notion of fairness or inequality aversion in addition the results suggest that efficiency concerns are not confined to students of economics but are important to students of all disciplines

are compact cities environmentally friendly there is a wide consensus among international institutions and national governments in favor of compact i e densely populated cities as a way to improve the ecological performance of the transport system indeed when both the intercity and intra urban distributions of activities are given a higher population density makes cities more environmentally friendly because the average commuting length is reduced however when we account for the possible relocation of activities within and between cities in response to a higher population density the latter may cease to hold indeed an increasing density policy affects prices wages and land rents which in turn incentivizes firms and households to change place this reshapes the urban system in a way that may generate a higher level of pollution thus although an increase in compactness is environmentally desirable when locations are given compactness may not be environmentally friendly when one accounts for the general equilibrium effects generated by such a policy

social preferences self interest and the demand for redistribution preferences for redistribution may be influenced by values and beliefs about distributive justice as well as by self interest people may prefer more redistribution to the poor if they believe that poverty is caused by circumstances beyond individual control therefore beliefs about the causes of income may affect demand for redistribution alternatively the effect of these beliefs on redistributive preferences may be spurious if they are correlated with income and self interest is not properly controlled for they may also measure incentive cost concerns using social survey data i find that self interest cannot explain the effect of these beliefs on redistributive preferences 2001 elsevier science b v all rights reserved

the impact of climate change on the balanced growth equivalent an application of fund the stern review added balanced growth equivalents bge to the economic climate change research agenda we first propose rigorous definitions of the bge for multiple regions and under uncertainty we show that the change in the bge is independent of the assumed scenario of per capita income for comparable welfare economic assumptions as the stern review we calculate lower changes in bge between a business as usual scenario and one without climate impacts with the model fund than the stern review found with the model page we find that mitigation policies give even lower changes in bge and argue that those policy choices should be the focus of the research effort rather than total damage estimates according to our results the current carbon tax should be below 55 tc sensitivity analyses show that the stern review chose parameters that imply high impact estimates however for regionally disaggregated welfare functions we find changes in bge that are significantly higher than the results from the stern review both for total damage as for policy analysis with regional disaggregation and high risk aversion we observe fat tails and with that very high welfare losses

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

trends in road freight transportation carbon dioxide emissions and policies in china we adopted the simple average divisia index approach to explore the impacts of factors on the carbon dioxide co2 emissions from road freight transportation in china from 1985 to 2007 co2 emissions were investigated using the following as influencing factors the emission coefficient vehicle fuel intensity working vehicle stock per freight transport operator market concentration level freight transportation distance market share of road freight transportation ton kilometer per value added of industry industrialization level and economic growth building on the results we suggest that economic growth is the most important factor in increasing co2 emissions whereas the ton kilometer per value added of industry and the market concentration level contribute significantly to decreasing co2 emissions we also discussed some recent important policies concerning factors contained in the decomposition model

total factor carbon emission performance of fossil fuel power plants in china a metafrontier non radial malmquist index analysis article i nfo this paper proposes the metafrontier non radial malmquist co2 emission performance index mnmcpi for measuring dynamic changes in total factor co2 emission performance over time the mnmcpi method allows for the incorporation of group heterogeneity and non radial slack into the previously introduced malmquist co2 emission performance index mcpi we derive the mnmcpi by solving several non radial data envelop ment analysis dea models we decompose the mnmcpi into an efficiency change ec index a best practice gap change bpc index and a technology gap change tgc index and based on the proposed indices we examine the dynamic changes in co2 emission performance and its decomposition of fossil fuel power plants in china for the 2005 2010 period the empirical results show a 0 38 increase in total factor co2 emission performance as a whole and a u shaped mnmcpi curve for the sample period because companies owned by the central government lack innovation and technological leadership the results suggest a missing link in the role of the central government in promoting co2 emission performance

role dependent social preferences bargaining results emerge from the interplay of strategic options and social preferences for every bargaining game however the advantage of a player having certain preferences in terms of negotiated equilibrium revenues might differ we explore the hypothesis that preferences change according to the players strength combination simple 1 1 bargaining experiments from the literature are discussed and 2 2 as well as 2 3 assignment market experiments with possible renegotiations are investigated the assumption that players adopt preferences for two to five roles defined by strength combinations of the two bargainers explains the experimental results better than individually constant preferences

a leaky bucket in the real world estimating inequality aversion using survey data existing evidence of inequality aversion relies on data from class room experiments where subjects face hypothetical questions this paper estimates the magnitude of inequality aversion using representative survey data with questions related to the real economy situations the respondents face the results reveal that inequality aversion can be measured in a meaningful way using survey data but the magnitudes of the estimates depend dramatically on how inequality aversion is measured no matter how measured the revealed inequality aversion predicts opinions on a wide range of questions related to the welfare state such as the level of taxation tax progressivity and the structure of unemployment benefits

the decrease of co2 emission intensity is decarbonization at national and global levels abstract this viewpoint proposes the definition decarbonization refers to a decrease of co2 emission intensity in a trend this viewpoint then argues that an analysis of decarbonization at national and global levels based on that definition would lead to the correct calculation of decarbonization

analysis of energy efficiency and energy savings potential in china s provincial industrial sectors abstract because industrial sectors in china are energy intensive improving energy efficiency and promoting energy savings in these sectors are of great importance for the further sustainable development of china s economy using a proposed meta frontier data envelopment analysis dea this paper analyzes the total factor energy efficiency and energy savings potential in china s provincial industrial sectors for the years 2000 2014 from three perspectives namely the technology gap management and scale the results indicate that 1 driven by technological progress energy efficiency during the sample period was greatly improved though the expansion of technology gaps between regions and the decline in scale efficiency represented two significant handicaps 2 the current energy efficiency in china s industrial sectors remains extremely low indicating that there is considerable potential for energy efficiency improvement and energy savings and 3 the sources of energy inefficiency and energy savings potential in china s industrial sectors exhibit spatially distinct characteristics accordingly it is determined that most of china s eastern provinces should focus on improving scale and management efficiency whereas most of its central and western provinces should concentrate on three factors narrowing the regional technology gap improving management efficiency and optimizing the industrial scale

dea approach for unified efficiency measurement assessment of japanese fossil fuel power generation this study discusses a new dea data envelopment analysis approach to measure the unified operational and environmental efficiency of energy firms it is widely known that they produce not only desirable good outputs e g electricity but also undesirable bad outputs e g co2 as a result of their plant operations the proposed approach incorporates an output separation desirable and undesirable outputs for the performance evaluation of energy firms in addition to the output separation this study separates inputs into energy and non energy inputs consequently the proposed approach incorporates not only the output separation but also the input separation within a computational framework of dea non radial measurement this study compares the proposed approach with other previous dea approaches used for the performance evaluation of energy firms after the methodological comparison this study applies the proposed approach for measuring the unified efficiency of japanese fossil fuel power generation this empirical study confirms that the implementation of kyoto protocol 2005 has not been effective on the unified efficiency of japanese fossil fuel power generation during the observed period 2004 2008 although the empirical result is inconsistent with the current japanese environmental policy under kyoto protocol it contains policy implications for guiding the future direction of japanese environmental policy on the electric power industry

does factor market distortion inhibit the green total factor productivity in china abstract this article measures green total factor productivity gtfp to discuss whether factor market distortions inhibit the green development of china s economy meanwhile export and foreign direct investment fdi are taken into account based on a threshold model considering export and fdi are closely related to factor market distortion environment and the economy the result shows that the factor market distortion has negative influences on china s gtfp growth export and fdi s spillover effect significantly moreover factor market distortion was found to be the threshold of export and fdi s spillover effect leading to inferior export and fdi which further inhibit gtfp growth this article provides a supplement to the issue from the perspective of environment based on the widely confirmed proposition that factor market distortion inhibits tfp growth according to the results we suggest that the chinese government should reduce the control of factor market as much as possible leaving the factor resources allocation to the market this will not only promote an innovation driven development but also an energy saving and environment friendly economy in china the article provides a new perspective on the influence mechanism of export and fdi on gtfp growth by discussing the impact path of factor distortion and expands the empirical framework of the research direction as well
