a review of wta wtp studies abstract willingness to accept wta is usually substantially higher than willingness to pay wtp these constructs have been studied for roughly 30 years and with a wide variety of goods this paper reviews those studies we find that the less the good is like an ordinary market good the higher is the ratio the ratio is highest for non market goods next highest for ordinary private goods and lowest for experiments involving forms of money a generalization of this pattern holds even when we account for differences in survey design ordinary goods have lower ratios than non ordinary ones we also find that ratios in real experiments are not significantly different from hypothetical experiments and that incentive compatible elicitation yields higher ratios

sustainability development for supply chain management in u s petroleum industry by dea environmental assessment abstract environmental assessment and protection are important concerns in modern business consumers are interested in environmental protection they avoid purchasing products from dirt imaged companies even if their prices are much less than the ones produced by green imaged companies the green image is very important for business survivability in our global market a business concern associated with the green image is how to attain corporate sustainability where companies can attain both economic success and pollution prevention in their operations there is tradeoff between economic prosperity and environmental concern to attain a high level of corporate sustainability companies need to measure the current performance in terms of their operational and environmental achievements this study proposes a use of data envelopment analysis dea for such assessment the proposed dea assessment provides corporate leaders and managers with not only the measure of corporate sustainability but also information regarding how to invest for technology innovation for abatement of undesirable outputs e g co 2 as an application this study utilizes the proposed approach to measure the corporate sustainability of petroleum firms in the united states the petroleum industry is functionally separated into integrated and independent companies the integrated companies referred to as major have their large supply chains for both upstream e g exploration development and production of crude oil or natural gas and downstream e g oil tankers refineries storages and retails meanwhile the independent companies focus upon the upstream function but not the downstream in their business operations the empirical comparison between the two groups of petroleum firms identifies that the integrated companies outperform the independent companies because a large supply chain incorporated into the former group provides them with both a scale merit in their operations and an opportunity to obtain consumer s opinions on their business operations thus the large supply chain system covering business functions for upstream and downstream enhances corporate sustainability in the u s petroleum industry it is easily envisioned that the empirical findings discussed in this study are useful in preparing business strategy and industrial policy for the petroleum industry of not only the united states but also other nations involved in oil and gas production

effects of financial innovations on the money demand function a canadian evidence a money demand function for the candian economy has been estimated to explore if recent financial innovations have caused any significant change in the structural relationship between the demand for money and its determinants two sets of estimation results have been analysed the first set is obtained by estimating a standard money demand function for several overlapping sample periods and the other set is obtained by estimating a modified version which included a dummy or a ratchet variable to capture the effects of innovations the estimated equations have been used to generate ex post simulations and forecasts the results suggest that innovations have displaced the money demand function in the early 1980s it also appears that the incorporation of approriate innovation variables improves the predictive performance of the money demand function

sequential negotiations with loss averse buyers abstract this paper analyzes sequential negotiations with exogenous breakdown risk between a risk neutral seller and a loss averse buyer who is privately informed about his valuation i show that compared to the risk neutral benchmark loss aversion on the buyer s side softens the rent efficiency trade off for the seller the reason is that the higher the buyer s valuation is the more he has to lose by rejecting the seller s offer thus in equilibrium the seller s profits and overall efficiency are both higher than in the risk neutral case moreover i also show that loss aversion has a redistributive effect by increasing the equilibrium payoff of some low valuation buyers and decreasing that of high valuation ones

comparison among u s industrial sectors by dea environmental assessment equipped with analytical capability to handle zero or negative in production factors abstract a green image is recently an important component of corporate sustainability in modern business by extending the two previous works i e wang et al 2014 sueyoshi and wang 2014a this study discusses a new use of data envelopment analysis dea for environmental assessment by incorporating an analytical capability to handle zero and or negative in a data set the proposed approach provides us with not only new quantitative assessment on unified operational and environmental performance of firms but also information regarding how to invest for eco technology innovation for abating an amount of their industrial pollutions according to the previous studies the energy industry is an attractive investment target if desirable outputs are measured by return on assets roa as a short term concern and an amount of co 2 emission reduction the selection on a desirable output combination is important in understanding the corporate sustainability of the energy industry because it is the largest emitter among seven industry sectors examined in the previous studies however if the roa is replaced by a corporate value measured by tobin s q ratio as a long term concern the energy industry is not so attractive because it uses a very large production process so that green investment does not immediately increase the corporate value an empirical problem of these previous studies is that they have investigated only successful companies with positive roa or tobin s q ratios the analytical feature clearly indicates a methodological drawback of their studies in contrast this study pays attention to both successful companies with positive net incomes and unsuccessful companies with negative net incomes so being able to measure all aspects of their performance in a short term concern this study finds that the energy industry exhibits a high level of potential on green investment however the energy industry may be not attractive even in the short term concern i e net income partly because governmental regulations on their operation and pollution prevention efforts are stricter than the other industrial sectors this result may be seemingly inconsistent with wang et al 2014 rather the result indicates that successful energy firms can attain the corporate sustainability by investing eco technology innovation but unsuccessful ones cannot attain the sustainability even in the short term concern because they do not have large capital accumulation for eco technology investment whose importance has been first discussed by sueyoshi and goto 2010a in other words the eco technology investment for enhancing a high level of corporate sustainability depends upon an amount of net income generated by each energy firm

marginal rate of transformation and rate of substitution measured by dea environmental assessment comparison among european and north american nations this study discusses the new use of dea data envelopment analysis environmental assessment to measure mrt marginal rate of transformation and rs rate of substitution among production factors e g inputs desirable and undesirable outputs to measure the degree on mrt and rs this study first examines a concept of disposability from the perspective of economic strategies to combat various environmental issues the strategies are extendable to a policy change for pollution prevention the underlying concept is separated into natural and managerial disposability under managerial disposability it is possible for us to measure an occurrence of desirable congestion or eco technology innovation considering the disposability concept this study discusses how to measure the type and magnitude of mrt and rs a problem of the mrt rs measurement is that these measures usually become unstable e g very large or small in these magnitudes because dea does not assume any functional form for economic activities to overcome such a difficulty this study equips dea environmental assessment with multiplier restriction by utilizing a unique feature on a proposed data treatment the multiplier restriction in dea has been never explored in previous works on environmental assessment in an application this study finds three important economic concerns on europe and north america first western europe outperforms eastern europe and north america in their unified efficiency measures under managerial disposability this study statistically confirms a difference between western and eastern europe but not between western europe and north america this result exhibits that eastern europe is not yet well developed at the level of the other two regions second eastern europe has exhibited mrt estimates that are different from western europe and north america the nations in eastern europe have an economic potential for industrial developments because the level of their industrial pollutions is less than that of the other two regions the potential is also found in their mrt estimates finally an interesting difference can be found in the rs estimate between eastern europe and western europe from 2008 to 2012 they have statistically exhibited a difference between the two regimes but not with north america this is because most nations in both western europe and north america have already attained a high level of economic successes so that they have a limited industrial potential under current production technology and eco technology the situation of the two regions will be changed along with new technology development in contrast eastern europe is different from the other two regions in terms of attaining such a level of social sustainability because of limited capital accumulation and limited opportunity for technology innovation

correlates of narrow bracketing we examine whether different phenomena of narrow bracketing can be traced back to some common characteristic and whether and how different phenomena are related we find that making dominated lottery choices or ignoring the endowment when making risky choices are related phenomena and are both associated with low levels of cognitive reflection in contrast the phenomena of setting narrow goals or narrow mental budgets seem not to reflect choice errors due to low cognitive reflection but are tools to overcome self control problems buying small scale insurance is associated with having narrow mental budgets suggesting that people buy such insurance to insure themselves against the consequences of their own self control strategy

dea radial and non radial models for unified efficiency under natural and managerial disposability theoretical extension by strong complementary slackness conditions abstract this study proposes a use of data envelopment analysis dea for environmental assessment all radial and non radial models are discussed under natural and managerial disposability the natural disposability implies corporate strategy by which a firm attempts to decrease an input vector to decrease a vector of undesirable outputs given the decreased input vector a firm attempts to increase a vector of desirable outputs as much as possible this type of strategy supported by economists indicates negative adaptation to a regulation change on undesirable outputs in contrast the managerial disposability indicates opposite strategy by increasing the input vector this disposability expresses corporate strategy by which a firm considers the regulation change as a new business opportunity a firm attempts to improve its performance by utilizing new environmental technology and or new management this type of strategy supported by corporate strategists in u s business schools indicates positive adaptation to the regulation change on undesirable outputs using the proposed dea assessment this study examines the relationship among energy consumption economic development and environmental protection in japanese prefectures to theoretically extend the use of dea for environmental assessment this study incorporates strong complementary slackness conditions scscs into the proposed radial models the incorporation of scscs has three methodological strengths first dea scscs can handle an occurrence of multiple reference sets and multiple projections second the incorporation of scscs makes it possible to restrict dual variables multiples in a specific range without any prior information finally dea scscs can bypass the conventional procedure i e a radial model combined with an additive model used for dea radial measurement

the disparity between willingness to accept and willingness to pay measures of value psychologists have long argued that people are much more averse to a loss than attracted to an equivalent gain this behavior termed loss aversion has been formalized by kahneman and tversky 1979 in their reformulation of expected utility theory prospect theory in prospect theory the utility function is replaced by a value function that evaluates changes in income from the current level increases in income are weighted by a relatively small marginal utility decreases in income are weighted by a much larger marginal utility in effect the value function implies that a kink in the relationship between utility and income occurs at the initial income or reference point and that the slope of the utility function for losses in income is steeper than it is for gains in a recent paper knetsch and sinden 1984 report a series of experiments that demonstrate the existence of a large disparity between willingness to accept wta and willingness to pay wtp measures of value they argue that the psychological theory of loss aversion explains this difference economic theory would suggest that individuals who exhibit a large disparity between wta and wtp are perhaps underperceiving the value of gains or overperceiving the value of losses are behaving in an irrational manner and will consequently achieve a lower level of well being than if they behaved in a true utility maximizing manner this would in contrast to loss aversion usually imply near equal values for wta and wtp see willig 1976 further documentation of a larger than expected disparity between wta and wtp has been obtained in surveys asking for the value of a variety of public goods for example cummings brookshire and schulze 1986 document six

salience in experimental tests of the endowment effect starting with knetsch 1989 experiments on the endowment effect thaler 1980 typically rely on a two stage procedure in the first stage subjects are endowed with a good such as a mug in the second stage the same subjects are given the opportunity to trade this good for another good of similar value such as a pen the endowment effect holds that very few subjects chose to trade sometimes as few as ten percent in related experiments subjects state selling prices for their endowment that are much higher than their buying prices for the same good these patterns are hard to reconcile with standard choice theory which predicts that about half the subjects would trade and that selling prices and buying prices are similar the common explanation of this evidence relies on prospect theory s loss aversion tversky and kahneman 1979 because the pain of parting with the endowment looms larger in the decision maker s mind than the pleasure of acquiring a good of similar value kahneman knetsch and thaler 1990 a decision maker endowed with a mug is unwilling to trade it for a

substitutability among undesirable outputs in recent years economists have started to move beyond calculating regulatory effects on a pollutant by pollutant basis since their interaction is important in this study we take up this issue to allow for joint production of multiple pollutants and marketable output we specify our technology using a directional distance function this allows us to treat pollutants as joint outputs yet accounts for their undesirability we estimate the distance function for a sample of coal fired electric power plants from 1985 to 1998 which includes the first 4 years of phase i of the clean air act amendments of 1990 we focus on the interaction between so2 and no x as they became more highly regulated and estimate shadow prices of the pollutants and the morishima elasticity of transformation between two pollutants no x and so2 as well as with respect to the desirable output kilowatt hours of electricity as expected we find that power plants increase no x emissions as they decrease so2 i e they are subs

eco efficiency analysis of power plants an extension of data envelopment analysis abstract in public discussion on environmental policy the notion of eco efficiency is often used the joint production of goods and undesirable outputs such as pollutants which may not be freely disposable without costs causes difficulties to measure the overall performance of the firm because of the absence of market prices for the undesirable outputs we are not able to estimate the environmental costs some of the measurement and evaluation difficulties can be overcome by employing data envelopment analysis dea as the efficiency measurement vehicle we propose the use of two different approaches in the first approach we start by decomposing the problem into two parts 1 the problem of measuring technical efficiency as the relation of the desirable outputs to the inputs and 2 the problem of measuring so called ecological efficiency as the relation of the desirable outputs to the undesirable outputs separately those two efficiency indicators are then combined in the second approach we treat pollutants as the inputs in the sense that we wish to increase desirable outputs and decrease pollutants and inputs the approaches are applied to the problem of measuring the efficiency of 24 power plants in a european country

japanese fuel mix strategy after disaster of fukushima daiichi nuclear power plant lessons from international comparison among industrial nations measured by dea environmental assessment in time horizon abstract on june 1 2015 the japanese government has announced that the fuel mix will consist of nuclear generation with a range between 20 and 22 and renewable generation with a range between 22 and 24 of the total electricity generation by 2030 a difficulty in understanding the governmental future energy plan is that it does not contain any scientific evidence concerning why japan needs to maintain the amount of nuclear generation and that of renewable at the level between 20 and 22 and between 22 and 24 respectively to investigate the future energy plan this study uses data envelopment analysis dea as a methodology the proposed dea approach incorporates the property of translation invariance the property indicates that an efficiency measure should not be influenced even if inputs and or outputs are shifted toward a same direction by adding or subtracting a specific real number the property makes it possible that we can evaluate the performance of organizations whose production factors i e inputs desirable and undesirable outputs contain many zeros and negative values in a data set such an occurrence of zero and negative in production factors is widely observed in many dea performance evaluations this study first uses the desirable property for dea environmental assessment in a time horizon the proposed dea environmental assessment identifies that the reasonable ranges for japanese future fuel mix are a combustible fuel generation within the range between 34 5 and 56 1 b hydro generation within the range between 22 4 and 40 5 c nuclear generation within the range between 10 4 and 13 7 d pumped hydro generation within the range between 3 9 and 6 9 and e renewable generation within the range between 3 7 and 8 4 all of which are measured by these generation capacities it is clearly identified that the future fuel mix proposed by the japanese government is inconsistent with the estimated one which we determine by relatively comparing it with the energy structures of 33 industrial nations the comparison indicates that the japanese future energy plan will be too ambitious to implement the future goal it is easily envisioned that the energy plan will have a considerable difficulty in future it is hoped that the electric power industry can access drastic technological advancements including eco technology innovation and then japan will be able to change the future direction on fuel mix as the government expects

competition and price variation when consumers are loss averse we modify the salop 1979 model of price competition with differentiated products by assuming that consumers are loss averse relative to a reference point given by their recent expectations about the purchase consumers sensitivity to losses in money increases the price responsiveness of demand and hence the intensity of competition at higher relative to lower market prices reducing or eliminating price variation both within and between products when firms face common stochastic costs in any symmetric equilibrium the markup is strictly decreasing in cost even when firms face different cost distributions we identify conditions under which a focal price equilibrium where firms always charge the same focal price exists and conditions under which any equilibrium is focal

disappointment in decision making under uncertainty decision analysis requires that two equally desirable consequences should have the same utility and vice versa most analyses of financial decision making presume that two consequences with the same dollar outcome will be equally preferred however winning the top prize of 10 000 in a lottery may leave one much happier than receiving 10 000 as the lowest prize in a lottery this paper explores the implications of disappointment a psychological reaction caused by comparing the actual outcome of a lottery to one s prior expectations for decision making under uncertainty explicit recognition that decision makers may be paying a premium to avoid potential disappointment provides an interpretation for some known behavioral paradoxes and suggests that decision makers may be sensitive to the manner in which a lottery is resolved the concept of disappointment is integrated into utility theory in a prescriptive model

the impacts of the clean air act on production cost and the substitution between inputs in the electric utility industry abstract the paper examines how having to comply with phase 1 of title iv of the 1990 clean air act affected production cost and the substitution between fuel and non fuel labor capital inputs phase 1 required firms to reduce their sulfur dioxide emissions enacting procedures to reduce sulfur dioxide emissions using lower sulfur content coal or other fuel sources could lead to higher cost and impact the substitution between fuel and non fuel inputs using a 1992 2000 panel of 34 u s electric utilities empirical results indicate that the procedures electric utilities enacted to comply with phase 1 contributed to small increases in both marginal cost and total cost firms having to comply with phase 1 were more willing than firms not subject to phase 1 to substitute from fuel to non fuel labor capital inputs following an increase in the price of fuel utilities subject to phase 1 that had a fuel clause were more willing than phase 1 firms without a fuel clause to substitute from non fuel inputs to fuel when the price of the non fuel input increased

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

dea environmental assessment on u s industrial sectors investment for improvement in operational and environmental performance to attain corporate sustainability abstract environmental assessment has recently become an important business concern because consumers are interested in environmental protection they try to avoid purchasing products from dirt imaged companies which do not pay attention to environmental protection even if their prices are much less than the ones produced by green imaged companies thus a green image is very important for corporate survivability in a global market this study considers corporate sustainability indicating that companies need to consider both economic prosperity and pollution prevention in their operations to discuss the issue from corporate strategy for modern business this study discusses a use of data envelopment analysis dea for environmental assessment by focusing upon research and development r d strategy as well as technology innovation and selection for reduction of undesirable outputs e g co 2 emission this type of research has never been explored in previous studies it is easily envisioned that the proposed dea environmental assessment will guide corporate leaders in identifying how to invest for technology innovation to reduce an amount of undesirable outputs to discuss the practicality this study applies the proposed approach to 153 observations on s p 500 corporations in 2012 and 2013 the empirical investigation confirms that investors pay more serious attention to company s green image and the reality for a long run sustainability than profitability in a short run concern furthermore the energy sector is the best investment target among seven industrial sectors examined in this study the measurement of corporate sustainability can serve as an empirical basis in selecting what type of technology is fitted for a specific industry

a theory of disappointment aversion an axiomatic model of preferences over lotteries is developed it is shown that this model is consistent with the allais paradox includes expected utility theory as a special case and is only one parameter beta richer than the expected utility model allais paradox type behavior is identified with positive values of beta preferences with positive beta are said to be disappointment averse it is shown that risk aversion implies disappointment aversion and that the arrow pratt measures of risk aversion can be generalized in a straight forward manner to the current framework copyright 1991 by the econometric society

data envelopment analysis for environmental assessment comparison between public and private ownership in petroleum industry abstract environmental assessment recently becomes a major policy issue in the world this study discusses how to apply data envelopment analysis dea for environmental assessment an important feature of the dea environmental assessment is that it needs to classify outputs into desirable good and undesirable bad outputs because private and public entities often produce not only desirable outputs but also undesirable outputs as a result of their production activities this study proposes the three types of unification for dea environmental assessment by using non radial dea models the first unification considers both an increase and a decrease in the input vector along with a decrease in the direction vector of undesirable outputs this type of unification measures unified efficiency the second unification considers a decrease in an input vector along with a decrease in the vector of undesirable outputs this type of unification is referred to as natural disposability and measures unified efficiency under natural disposability the third unification considers an increase in an input vector but a decrease in the vector of undesirable outputs this type of unification is referred to as managerial disposability and measures unified efficiency under managerial disposability all the unifications increase the vector of desirable outputs to document their practical implications this study has applied the proposed approach to compare the performance of national oil firms with that of international oil firms this study identifies two important findings on the petroleum industry one of the two findings is that national oil companies under public ownership outperform international oil companies under private ownership in terms of unified operational and environmental efficiency and unified efficiency under natural disposability however the performance of international oil companies exhibits an increasing trend in unified efficiency the other finding is that national oil companies need to satisfy the environmental standard of its own country while international oil companies need to satisfy the international standard that is more restricted than the national standards as a consequence international oil companies outperform national oil companies in terms of unified efficiency under managerial disposability

modeling loss aversion and reference dependence effects on brand choice based upon a recently developed multiattribute generalization of prospect theory s value function tversky and kahneman 1991 we argue that consumer choice is influenced by the position of brands relative to multiattribute reference points and that consumers weigh losses from a reference point more than equivalent sized gains loss aversion we sketch implications of this model for understanding brand choice we develop a multinomial logit formulation of a reference dependent choice model calibrating it using scanner data in addition to providing better fit in both estimation and forecast periods than a standard multinomial logit model the model s coefficients demonstrate significant loss aversion as hypothesized we also discuss the implications of a reference dependent view of consumer choice for modeling brand choice demonstrate that loss aversion can account for asymmetric responses to changes in product characteristics and examine other implications for competitive strategy

an endowment effect for risk experimental tests of stochastic reference points recent models of reference dependent preferences indicate that expectations may play a prominent role in the presence of behavioral anomalies a subset of such expectations based models predicts an endowment effect for risk that risk attitudes differ when reference points change from certain to stochastic in two purposefully simple risk preference experiments eliminating often discussed confounds i demonstrate both between and within subjects such an endowment effect for risk these results provide needed separation between expectations based reference dependent models allow for evaluation of recent theoretical extensions and may help to close a long standing debate in decision science on inconsistency between utility elicitation methodologies

are adults better behaved than children age experience and the endowment effect we find that large increases in age do not reduce the endowment effect supporting the hypothesis that people have reference dependent preferences which are not changed by repeated experience getting and giving up goods

cognitive performance in competitive environments evidence from a natural experiment competitive situations that involve cognitive performance are widespread in labor markets schools and organizations including test taking competition for promotion in firms and others this paper studies cognitive performance in a high stakes competitive environment the analysis takes advantage of a natural experiment that randomly allocates different emotional states across professional subjects competing in a cognitive task the setting is a chess match where two players play an even number of chess games against each other alternating the color of the pieces white pieces confer an advantage for winning a chess game and who starts the match with these pieces is randomly decided the theoretical analysis shows that in this setting there is no rational reason why winning frequencies should be better than 50 50 in favor of the player drawing the white pieces in the first game yet we find that observed frequencies are about 60 40 differences in performance are also stronger when the competing subjects are more similar in cognitive skills we conclude that the evidence is consistent with the hypothesis that psychological elements affect cognitive performance in the face of experience competition and high stakes

new network data envelopment analysis approaches an application in measuring sustainable operation of combined cycle power plants abstract nowadays organizations deal with numerous economic environmental and social problems to have sustainable operations they have begun to incorporate environmental and social concerns into conventional economic objectives a combined cycle power plant ccpp is a good instance of an open system with multistage processes and interconnected activities efficiency evaluation of ccpps is a complex task since there exist a variety of inputs outputs which enter into any stages of network additionally there might be intermediate products which are consumed by the same power plants we call such factors loop intermediate measures to measure efficiency of ccpps network data envelopment analysis ndea is used this paper proposes new ndea models to evaluate efficiency of ccpps the proposed models calculate the efficiency of power plants and their sub sectors under both crs constant returns to scale and vrs variable returns to scale assumptions this paper provides a comprehensive analysis for returns to scale we apply the new ndea models to measure relative efficiency of ccpps

radial and non radial approaches for environmental assessment by data envelopment analysis corporate sustainability and effective investment for technology innovation abstract environmental assessment and protection are important concerns in modern business consumers are interested in corporate effort and investment for environmental protection it can be easily imagined that they avoid purchasing products from dirty imaged companies even if their prices are much less than the ones produced by green imaged companies a green image is recently a very important concern for corporate survivability in a competitive global market by extending previous works on environment assessment and corporate sustainability where companies need to consider both economic prosperity and pollution prevention in their operations this study discusses a new use of data envelopment analysis dea for environmental assessment by utilizing its radial and non radial measurements the proposed radial and non radial approaches may guide corporate leaders managers and policy makers by providing not only quantitative assessment on their efforts for environmental protection but also information regarding how to invest for technology innovation on abatement of undesirable outputs the empirical investigation identifies that the green investment in u s energy industry is useful for improving its unified operational and environmental performance if operational performance is measured by roa return on assets and an amount of co 2 emission reduction because the industry is the largest emitter among seven industry sectors examined in this study the green investment makes it possible that firms can increase their net incomes by a good corporate image however if the financial measure is replaced by a corporate value i e tobin s q ratio mainly measured by stock price the energy industry does not exhibit the best investment opportunity because the effect of green investment is limited on enhancing its corporate value the energy industry is a very large process industry so that the green investment does not immediately increase its corporate value as found in the other industrial sectors such as information technology industry

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

expectations as endowments evidence on reference dependent preferences from exchange and valuation experiments while evidence suggests that people evaluate outcomes with respect to reference points little is known about what determines them we conduct two experiments that show that reference points are determined at least in part by expectations in an exchange experiment we endow subjects with an item and randomize the probability they will be allowed to trade subjects that are less likely to be able to trade are more likely to choose to keep their item in a valuation experiment we randomly assign subjects a high or low probability of obtaining an item and elicit their willingness to accept for it the high probability treatment increases valuation of the item by 20 30 copyright 2011 oxford university press

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

is the endowment effect an expectations effect a hallmark result within behavioral economics is that individuals choices are affected by current endowments a recent theory due to k szegi and rabin 2006 quarterly journal of economics 121 1133 1165 explains such endowment effect with a model of expectations based reference dependent preferences departing from past work we conduct complementary experiments to disentangle expectations verified probabilistic beliefs held by subjects from other features of endowment such as assignment to a good hence allowing us to compare the effect of expectations with that of other variations while mere assignment can affect choices we do not find a large role in the effect for k szegi rabin expectations

economic growth and the elasticity of substitution two theorems and some suggestions at the beginning of the twentieth century the work of the swedish economist knut wicksell 1901 marked an important advance in our understanding of the relationship between the structure of production functions and income distribution wicksell had asked the following question among many others suppose that the marginal productivities are equal to the remuneration rates of each factor what then should be the form of the corresponding production function he pointed out p 125 that the general integral of the partial differential equation implied by this relationship was of the form y lf kil which meant in turn that the product y was necessarily a homogeneous of degree one function of capital k and labor l as an example he gave a function where the shares of k and l in y were constant and wrote down the function which would be rediscovered decades later by charles w cobb and paul h douglas 1928 however it is only half a century later in robert m solow s nobel prize winning 1956 essay that implications between the structure of the production function and long run equilibrium or disequilibrium of the economy were drawn in his classic article a contribution to the theory of economic growth solow had considered three cases analytically other cases were also discussed geometrically using a phase diagram he had labeled the two first cases 1hlarrod domar and cobb douglas respectively and he referred to the third type of production function as offering a bit of variety it was y ak 2 l 2 2 a particular case of y akp lp 1p in those early days solow had not pointed out to the reader that his cases could have been numbered 0 1 and 2 following the elasticity of substitution of the corresponding production function it would be only five years later in 1961 that with his coauthors kenneth j arrow et al he would find the general form of the two factor constant elasticity of substitution ces production function by integrating the differential equation corresponding to the observed relationship between output per capita and the wage rate solow s third case was indeed highly interesting since it allowed the possibility of everincreasing income per head even without any technical progress indeed solow showed that due to the efficiency of the system entailed by the particular production function he had chosen there existed a threshold for the savings rates s to generate investment per head large enough for income per head to grow forever that threshold was s nla2 where n is the growth rate of the population it was then natural to ask whether one could express that threshold in terms of the elasticity of substitution a the value of that threshold was determined by de la grandville 1989 to be equal to s no3 or where a is k s coefficient in a normalized ces function equal to a in solow s third case where u 2 for any s and n values this relationship gives also the threshold value in implicit form by the solution of ao1 1 log 3q or ilog nls by totally differentiating the last relationship one could observe that the threshold for the elasticity of substitution to entail ever sustained growth was an in klump faculty of mathematics and economics university of ulm helmholtzstrasse 20 d 89081 ulm germany de la grandville department of economics university of geneva 102 boulevard carl vogt ch 1211 geneva 4 switzerland we gratefully acknowledge the comments of seminar participants at stanford university and at the universities of stuttgart hohenheim and munich where parts of the paper were presented also we would like to thank without implicating in any way robert solow for his insightful remarks and an anonymous referee for very helnfuil supgestions wicksell cobb and douglas would no doubt burst with pride if they knew that one of our first year students wrote in a paper of his of course we recognize here a kirk douglas production function

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

environmental assessment for corporate sustainability by resource utilization and technology innovation dea radial measurement on japanese industrial sectors abstract this study proposes a new use of dea data envelopment analysis radial approach to examine the corporate sustainability of japanese industrial sectors the concept of corporate sustainability is measured by its subcomponent measures including uen unified efficiency under natural disposability uem unified efficiency under managerial disposability uenm unified efficiency under natural and managerial disposability uei unified efficiency for intermediate measurement and uenm dc unified efficiency under natural and managerial disposability with desirable congestion among the five measures the uei examines a degree of how each firm can efficiently utilize its resources the uenm dc examines a degree of how the firm can reduce an amount of undesirable outputs by technology innovation and or managerial change such a combined use between uei and uenm dc has been never explored in dea environmental assessment the empirical results obtained from the proposed approach have identified two important implications one of the two implications is that the japanese energy industry has been long under governmental regulation so that energy firms do not have corporate governance capabilities at the level of other industrial sectors which are competing in a global market in particular the implication is applicable to japanese electric power firms it is necessary for them to change their corporate governances e g by adding new executive board members who have international experience and or woman executives as widely found in american and european energy industries so that they can pay attention to consumers not regulatory agencies of the japanese government the other implication is that technology innovation can more effectively improve the performance of the energy sector employing high efficiency and low carbon generation technologies to achieve desirable fuel mix is essential for improving the corporate sustainability of the japanese energy sector

weak and strong disposability vs natural and managerial disposability in dea environmental assessment comparison between japanese electric power industry and manufacturing industries the economic concept of weak and strong disposability has long dominated studies on dea data envelopment analysis environmental assessment this study reviews the two disposability concepts from their conceptual and methodological implications in particular this study is interested in the concept of weak disposability because the concept is believed to have an analytical capability to measure an occurrence of congestion the two economic concepts on disposability accepted by production economists are replaced by natural and managerial disposability in this study the natural disposability implies an environmental strategy by which a firm attempts to decrease an input vector to reduce a vector of undesirable outputs given the decreased input vector a firm attempts to increase a vector of desirable outputs as much as possible this type of strategy indicates negative adaptation in contrast the managerial disposability indicates an opposite strategy by increasing the input vector this disposability expresses an environmental strategy by which a firm considers a regulation change as a new business opportunity a firm attempts to improve its unified performance by utilizing new clean air technology and or new management the strategy indicates positive adaptation considering the two groups of disposability this study compares between weak strong disposability and natural managerial disposability in terms of their conceptual and methodological differences focusing upon the concept of congestion and technology innovation furthermore using the concept of natural and managerial disposability this study compares japanese electric power firms with manufacturing firms this study finds that the manufacturing firms outperform the electric power firms under natural disposability an opposite result is found under managerial disposability this empirical study also finds that the two groups of japanese firms have attained desirable good congestion due to technology innovation based upon such empirical results this study identifies two policy implications one of the two implications is that the two groups of japanese industries have attained a high level of technology innovation by a result of environmental regulation the other is that the electric power industry operates more efficiently to reduce the co2 emission than the manufacturing industries

procedures for eliciting time preferences we study three procedures to elicit attitudes toward delayed payments the becker degroot marschak procedure the second price auction and the multiple price list the payment mechanisms associated with these methods are widely considered as incentive compatible thus if preferences satisfy procedure invariance which is also widely and often implicitly assumed they should yield identical time preference distributions we find instead that the monetary discount rates elicited using the becker degroot marschak procedure are significantly lower than those elicited with a multiple price list we show that the behavior we observe is consistent with an existing psychological explanation of preference reversals

dea radial measurement for environmental assessment and planning desirable procedures to evaluate fossil fuel power plants abstract energy policy depends on a proper use of methodology in guiding a large energy issue such as the global warming and climate change dea is one of such methodologies that are often used for preparing environmental policy which is closely linked to various energy issues unfortunately the use of dea applied to environmental policy is insufficient often misguiding policy makers and other individuals who are involved in energy issues this study provides three guidelines for a use of dea in preparing environmental assessment first it is important to prepare both primal and dual formulations to confirm whether information regarding all production factors i e inputs desirable and undesirable outputs is fully utilized in dea assessment second dea has model variations in radial and non radial measurements it is necessary for us to examine environmental issues by different models in order to avoid a methodological bias existing in those empirical studies finally dea environmental assessment needs to incorporate the concept of natural and managerial disposability the natural disposability indicates that a firm negatively adapts a regulation change on undesirable outputs in contrast the managerial disposability indicates that a firm positively adapts the regulation change because the firm considers the regulation change as a new business opportunity

disappointment and dynamic consistency in choice under uncertainty the central proposition of disappointment theory is that an individual forms expectations about uncertain prospects and that if the actual consequence turns out to be worse than or better than that expectation the individual experiences a sensation of disappointment or elation generating a decrement or increment of utility which modifies the basic utility derived from the consequence by incorporating a simple disappointment elation function into a model of individual choice many observed violations of conventional expected utility axioms including violations of savage s sure thing principle and the isolation effect can be predicted and defended as rational and dynamically consistent behaviour

measuring substitution in monetary asset demand systems the allen elasticity of substitution aes is widely used to study monetary asset substitution and structural demand stability blackorby and russell showed that the aes is uninformative and that the morishima elasticity of substitution mes is the appropriate measure a point overlooked in the monetary literature use of improper measures can lead to incorrect inferences this article considers five alternative measures of substitution the aes the mes the hicksian and marshallian elasticities of demand and mundlak s unencountered but appealing constant cost elasticity of substitution selection of the substitution measure appropriate to respective research questions is addressed

returns to scale and damages to scale under natural and managerial disposability strategy efficiency and competitiveness of petroleum firms environmental assessment recently becomes a major policy issue all over the world this study discusses how to use data environment analysis dea for environmental assessment for planning corporate strategy and international competitiveness an important feature of dea environmental assessment is that it classifies outputs into desirable good and undesirable bad outputs because all private and public entities produce not only desirable outputs but also undesirable outputs as a result of their production activities this study proposes the two types of output unification for dea environmental assessment by using a non radial model one of the two output unifications is that it considers a decrease in an input vector along with a decrease in the vector of undesirable outputs this type of unification is referred to as natural disposability the other unification considers an increase in an input vector but a decrease in the vector of undesirable outputs this type of strategy is referred to as managerial disposability both unifications increase the vector of desirable outputs after developing the two concepts on disposability this study theoretically explores how to measure returns to scale rts under natural disposability and damages to scale dts under managerial disposability to document the practicality of the proposed approach this study applies it to compare the performance of national oil firms with that of international oil companies this study identifies four important findings on the petroleum industry first national oil companies outperform international oil companies in the unified efficiency under natural disposability second international oil companies outperform national oil companies in the unified efficiency under managerial disposability third national oil firms exhibit a mixed result on rts while international oil firms exhibit decreasing rts finally both national and international oil companies exhibit increasing dts implying that all oil firms need to decrease their operational sizes for improving their environmental performance on co2 emission as an alternative strategy the result suggests that they need to introduce technology innovation e g clean air technology into their business operations the technology based strategy has more practicality than the size reduction in their operations

methodological comparison among radial non radial and intermediate approaches for dea environmental assessment abstract this study compares three dea approaches for environmental assessment all of which are designed to examine the level of simultaneous achievement on economic prosperity and environmental protection so measuring the degree of sustainability development dea standing for data envelopment analysis has been widely applied for performance assessment in the past five decades a new type of applications is referred to as dea environmental assessment and it measures the performance of many organizations that utilize inputs to produce not only desirable outputs e g electricity but also undesirable outputs e g co 2 in the previous studies dea based performance evaluation for environment assessment is methodologically classified into radial or non radial category recently a new intermediate approach analytically locating between the radial and non radial measures has been proposed as the third alternative a use of the intermediate approach has several unique features all of which cannot be found in the radial and non radial ones the new approach measures the degree of unified inefficiency on each production factor and determines the level of total unified inefficiency from the average of the sum of these inefficiency scores this study discusses the analytical features by comparing the intermediate approach with the radial and non radial ones the methodological comparison attempts to convey a message that dea is indeed an important methodology but not perfect rather it is an approximation approach to examine the performance of various organizations many dea applications on energy and environment often suffer from a methodological bias implying that different approaches produce different empirical results thus in guiding a large policy issue such as the global warming and climate change it is necessary for us to compare several different approaches e g models and concepts to derive a reliable empirical suggestion the importance of such a message is applicable to not only dea but also the other types of empirical research in natural and social sciences therefore this study discusses the methodological bias issue from the practicality of the three dea approaches in assessing various concerns on energy and environment

china s regional sustainability and diversified resource allocation dea environmental assessment on economic development and air pollution abstract environmental protection including the prevention of air pollution and health hazard materials such as pm2 5 and pm10 is now a very serious policy issue in china after attaining the rapid economic growth and development the pm stands for particular matter indicating the size of both solid particles and liquid droplets found in air unfortunately the economic development has produced a serious healthcare problem in not only china and other surrounding nations to enhance people s healthcare and appeal a good national image to the world china is recently looking for the new industrial and environmental policy direction to attain social sustainability in terms of economic development and environmental prevention to discuss policy implications on the new policy direction this study utilizes data envelopment analysis dea for assessment on its regional performance by incorporating pm2 5 and pm10 as undesirable outputs along with two disposability concepts i e natural disposability and managerial disposability no previous dea study has incorporated the amount of pm2 5 and pm10 in empirical investigation using a simulated data set for the period of 2013 2014 this study measures the efficiency of municipality cities under four different types of regional classifications the empirical results indicate that the chinese government should distribute its economic resources to cities which locate in the northwest region including lanzhou xining yinchuan and urumqi and reinforce more strict regulation on energy consumptions for environmental prevention in major cities e g beijing tianjin shanghai and chongqing the industrial policy change from the economic growth to the environment protection is essential for the future of china which is currently the second largest economic power in the world the environmental protection can enhance the china s image of contributing in economics industry and environmental protection to all other nations it can be envisioned that the new policy effort reduces the regional imbalance and increases the social sustainability in china the empirical findings and policy implications discussed in this study are applicable to not only china but also other industrial and developing nations and those are useful in guiding their industrial and environmental policy development

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

environmental assessment by dea radial measurement u s coal fired power plants in iso independent system operator and rto regional transmission organization abstract the economic concept of weak and strong disposability on undesirable outputs dominated the previous discussions on dea data envelopment analysis radial measurement for environmental assessment this study reexamines the economic concept from the perspective of corporate strategies on how to adapt a regulation change on undesirable outputs the economic concept of disposability conventionally accepted by production economists is replaced by natural and managerial disposability in this study the natural disposability implies an environmental strategy that a firm attempts to decrease an input vector to reduce a vector of undesirable outputs given the decreased input vector the firm attempts to increase a vector of desirable outputs as much as possible this type of strategy indicates negative adaptation meanwhile the managerial disposability indicates an opposite strategy by increasing the input vector this disposability expresses an environmental strategy by which a firm considers a regulation change on undesirable outputs as a new business opportunity a firm attempts to improve its unified operational and environmental performance by utilizing new technology and or new management the strategy indicates positive adaptation considering the two types of disposability this study discusses how to measure unified efficiency under natural and managerial disposability by dea radial models to document the practicality of the proposed dea environmental assessment this study applies it to compare the performance of u s coal fired power plants under isos rtos independent system operators regional transmission organizations with that of the other power plants not belonging to any organization this study identifies two empirical findings one of the two findings is that the latter coal fired power plants outperform the former power plants belonging to isos rtos in terms of three efficiency measures this result indicates that isos and rtos do not provide an effective coordination for coal fired power plants at the level that can be found in the other power plants the other finding is that there is technological improvement in the operation of coal fired power plants

new york city cab drivers labor supply revisited reference dependent preferences with rational expectations targets for hours and income this paper reconsiders whether cabdrivers labor supply decisions reflect reference dependent preferences following botond koszegi and matthew rabin 2006 we construct a model with targets for hours as well as income both determined by rational expectations estimating using henry s farber s 2005 2008 data we show that the reference dependent model can reconcile his 2005 finding that drivers stopping probabilities are significantly related to hours but not income with the negative wage elasticity of hours found by colin camerer et al 1997 and farber 2005 2008 the model yields sensible estimates that avoid farber s 2008 criticism that drivers income targets are too unstable to allow a useful reference dependent model of labor supply

consumer choice on ecologically efficient water heaters marketing strategy and policy implications in japan abstract this study examines how consumers select ecologically efficient water heaters in japan energy conservation in household water heating is increasingly important for reducing an amount of co 2 emission because the share of water heating in household energy consumption is approximately 30 recently japanese households have widely used ecologically efficient electric heat pump water heaters eco cute or gas fired water heaters eco jozu the total number of such efficient water heaters sold in japan was more than 2 5 million at the end of 2008 this study investigates various factors and impacts of marketing strategy for promoting the appliances in japan we apply mixed and nested logit models to a disaggregated choice data on water heaters from 2004 to 2008 this study considers retail energy prices a government financial support and marketing activities as important factors for appliance selection in addition we consider consumers housing attributes such as floor space and age of building this empirical study finds two business implications one of the two implications is that an increase in an energy price may enhance a choice probability of eco cute and eco jozu because a price increase invites consumer s consciousness on energy conservation so that a cost reduction on energy consumption becomes essential in a use of the efficient appliances the other implication is that marketing activities especially by recommendations from sales representatives and or housing suppliers are important for consumer behaviors the other important findings are discussed in this study this business experience in japan is useful to the other countries where ecologically efficient water heaters are not popular at the current moment

investment strategy for sustainable society by development of regional economies and prevention of industrial pollutions in japanese manufacturing sectors abstract a balance between industrial pollution prevention and economic growth becomes a world wide issue to develop a sustainable society in many industrial nations to discuss the issue this study proposes a new use of dea environmental assessment to determine how to effectively allocate capital for developing regional industries the amount of capital is used to invest for technology innovation for both local economic growth and environmental protection in this study the proposed approach separates outputs into desirable and undesirable categories inputs are also separated into two categories one of which indicates an amount of investment on capital assets the other category is used for production activities the proposed approach unifies them by two disposability concepts this study has evaluated the performance of manufacturing industries in 47 prefectures local government units in japan by unified efficiency under natural disposability uen unified efficiency under managerial disposability uem and unified efficiency under natural and managerial disposability uenm the uenm is further separated into its two cases with and without a possible occurrence on desirable congestion or technology innovation on undesirable outputs this study has empirically confirmed that japanese manufacturing industries need to make their efforts to reduce greenhouse gas emissions and air pollution substances by investing in technology innovation furthermore most of economic activities are currently located at metropolitan regions e g tokyo in japan to develop a sustainable society japan needs to allocate capital into regions with a high level of investment effectiveness by shifting the manufacturing industries from the metropolitan regions to much promising local areas identified in this study such a shift along with technology innovation makes it possible to reduce air pollutions in the entire japan by balancing economic growth and pollution prevention this empirical study confirms that the proposed approach is useful in both guiding regional planning and developing a sustainable society it is easily envisioned that the proposed approach is useful for not only japan but also the other industrial and developing nations

dea environmental assessment in time horizon radial approach for malmquist index measurement on petroleum companies abstract the climate change and various pollutions have been influencing our societies and economies the environmental assessment to be discussed in this study is increasingly important because it serves as an initial step toward pollution prevention corporate leaders policy makers researchers and individuals who are interested in environmental protection have been paying attention to the assessment so that they can prepare policy suggestions on the global warming and climate change as a methodology for the assessment this study proposes a use of data environment analysis dea in a time horizon most of data sets on the climate change are sampled in a time series where the performance of organizations fluctuates every moment in applying the dea environmental assessment to such a data set it is necessary for us to classify outputs into desirable e g oil production and undesirable e g co 2 emission categories because all organizations usually produce not only desirable but also undesirable outputs as a result of their economic activities to unify the two different types of outputs this study incorporates the concept of natural and managerial disposability into the computational framework of dea and extends them into a time horizon for the research purpose this study incorporates malmquist index into the proposed dea environmental assessment to examine an occurrence of a frontier shift among multiple periods the frontier shift indicates a technology progress and or managerial innovation during an observed period the index is further separated into four subcomponents in a time horizon these subcomponents are differently expressed under the natural and managerial disposability thus eight different subcomponents on the malmquist index are proposed to measure the frontier shift as an application this study uses the proposed dea approach to examine whether the frontier shift due to technology progress occurs or not in the petroleum industry from 2005 to 2009 our empirical study finds that the industry has not exhibited any major frontier shift under natural disposability but showing a considerable frontier shift under managerial disposability in other words the petroleum firms have improved their environmental performance by eco technology to reduce an amount of co 2 emission during the observed annual periods

malmquist index measurement for sustainability enhancement in chinese municipalities and provinces abstract this study discusses a use of dea environmental assessment in a time horizon we use a radial approach to examine a dynamic change of index measures related to china s regional development and industrial pollution prevention in applying the proposed assessment to a time series data we need to examine components that produce a shift of an efficiency frontier in a time horizon a unique feature of the proposed assessment is that it incorporates a framework of malmquist index to examine the frontier shift among multiple periods here the frontier shift indicates a progress potential on technology development and or managerial improvement among observed periods thus it is not an efficiency measure rather the measurement eliminates inefficiency by shifting an organization to an efficiency frontier in this study the index is conceptually separated into 6 subcomponents which are further disaggregated into 12 different elements 6 subcomponents 2 disposability concepts under natural and managerial disposability concepts the proposed index measurement needs to consider a possible occurrence of a frontier crossover among different periods because technology diffusion on production activities usually has a time lag until it becomes really effective methodologically this study conveys the message that dea is an approximation method so being not perfect therefore it is necessary for us to use several different approaches e g potential improvement by measuring a frontier shift and efficiency analysis to obtain reliable empirical evidence as an application this study examines the level of sustainability related to 30 municipalities and provinces in china from 2003 to 2014 the following six policy implications are obtained in this study first all municipalities and provinces have made a considerable progress on their economies and pollution prevention efforts second the effect of the frontier crossover is limited in china because they attain a high level of their potentials on economic development and pollution prevention of course this effort is within the chinese boundary not international because this study does not compare them with other industrial nations third china needs to allocate its resources to western provinces at a level that it has used for coastal developments fourth the government should reinforce efforts on environmental protection in central and southern regions fifth the government has focused on the sustainability development in urban municipalities and provinces and then has gradually shifted the policy influence toward rural areas finally different empirical results are confirmed by the potential analysis which consists of the malmquist index measurement and the efficiency analysis both approaches need to be examined for future planning on chinese regional development

binary payment schemes moral hazard and loss aversion we modify the principal agent model with moral hazard by assuming that the agent is expectation based loss averse according to k o szegi and rabin 2006 2007 the optimal contract is a binary payment scheme even for a rich performance measure where standard preferences predict a fully contingent contract the logic is that due to the stochastic reference point increasing the number of different wages reduces the agent s expected utility without providing strong additional incentives moreover for diminutive occurrence probabilities for all signals the agent is rewarded with the fixed bonus if his performance exceeds a certain threshold

dea environmental assessment in a time horizon malmquist index on fuel mix electricity and co2 of industrial nations abstract climate change and global warming become a major policy issue in the world economic activities produce not only desirable outputs e g electricity but also undesirable outputs e g co 2 emission the important policy issue is how each nation can balance between economic development and environmental protection to attain a sustainable society in attaining the sustainable society environmental assessment is increasingly important because it can serve as an initial step toward the green growth of each nation for the purpose this study proposes a new use of dea data environment analysis for environmental assessment in a time horizon the proposed use of dea incorporates malmquist index to examine the degree of a frontier shift among multiple periods the frontier shift indicates a technology progress and or managerial innovation during an observed period the index is conceptually separated into six subcomponents which are further divided into twelve different subcomponents six subcomponents two disposability concepts under the natural and managerial disposability in the index measurement it is necessary for us to consider a frontier crossover among different periods because technology innovation usually has a time lag until it really appears as an empirical application this study utilizes the proposed approach to identify the relationship among fuel mix electricity and co 2 of ten industrial nations this study finds three important empirical findings first there is a time lag in technology innovation on electricity generation and co 2 emission reduction consequently it is necessary to consider the existence of a frontier crossover in assessing the electric power industry second nuclear generation as found in france as well as hydro and renewable energy as found in netherlands are important for the development of a sustainable society although the former is associated with a very high level of risk and the latter has a limited generation capacity finally the electric power industry has been making a corporate effort to reduce the amount of co 2 emission by utilizing nuclear and renewable energy

why do so few hold stocks the authors investigate why 75 percent of u s households do not hold stocks despite the equity premium and predictions of expected utility models the question is relevant for privatization asset pricing and tax progressivity issues they show that risk aversion per se heterogeneity of beliefs habit persistence time nonseparability and quantity constraints on borrowing do not account for the phenomenon a wedge between borrowing and lending rates and minimum investment requirements are plausible but empirically weak factors more promising explanations are inertia and departures from expected utility maximization there is also qualified support for nondiversifiable income risk as a contributing factor copyright 1995 by royal economic society

expected prices as reference points theory and experiments abstract i show theoretically that applying the model of k szegi and rabin 2006 to a simple purchasing decision where consumers are ex ante uncertain about the price realisation gives when changing the underlying distribution of expected prices rise to counterintuitive predictions in contrast with a good deal model where consumers are predicted to be disappointed rejoice when the realised price is perceived as being worse better than the other possible realisation while the underlying ideas of both models are similar with respect to expectation based reference points the different results come from the concept of personal equilibrium in k szegi and rabin 2006 the experimental results show some support for the simpler good deal model for a number of different real consumption goods though the support is weaker for goods that either have a salient market price or no market price outside of the experiment

the endowment effect and the reference state evidence and manipulations abstract recent reports suggest that the endowment effect may be due to conditions under which it is observed and explained by incentives long recognized in standard theory evidence from new experiments reported here provides empirical support for the role of the economic environment on people s perceived reference state and consequently on their valuations as suggested by koszegi and rabin koszegi b rabin m 2006 a model of reference dependent preferences quarterly journal of economics 121 1133 1165 and indicates that the disappearance of the valuation disparity is more likely due instead to conditions that weaken the perception of reference states further these conditions appear to be poor approximations of those that prevail in most cases for which valuations are normally made

deal or no deal decision making under risk in a large payoff game show we examine the risky choices of contestants in the popular tv game show deal or no deal and related classroom experiments contrary to the traditional view of expected utility theory the choices can be explained in large part by previous outcomes experienced during the game risk aversion decreases after earlier expectations have been shattered by unfavorable outcomes or surpassed by favorable outcomes our results point to reference dependent choice theories such as prospect theory and suggest that path dependence is relevant even when the choice problems are simple and well defined and when large real monetary amounts are at stake

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

weak disposability in nonparametric production analysis with undesirable outputs environmental economics and natural resources group at wageningen university in the netherlands weak disposability of outputs means that firms can abate harmful emissions by decreasing the activity level modeling weak disposability in nonparametric production analysis has caused some confusion this article identifies a dilemma in these approaches conventional formulations implicitly and unintentionally assume all firms apply uniform abatement factors however it is usually cost effective to abate emissions in those firms where the marginal abatement costs are lowest this article presents a simple formulation of weak disposability that allows for non uniform abatement factors and preserves the linear structure of the model

goal setting and energy conservation abstract this paper develops a theoretical model of consumer demand for an energy conservation program that involves non binding self set goals we present evidence from a northern illinois goal setting program aimed at reducing residential electricity consumption which is difficult to reconcile with standard preferences and is broadly consistent with a model of present biased consumers with reference dependent preferences we find that the need for commitment is correlated with program adoption higher pre adoption consumption and lower responsiveness to goals consumers choosing realistic goals persistently save substantially more achieving savings of nearly 11 than those choosing very low or unrealistically high goals

loss aversion and competition in vickrey auctions money ain t no good we present results from an experiment with a within subject design aimed at testing a unique prediction of expectations based reference dependent preferences and loss aversion in private value second price vickrey auctions if bidders have expectationsbased reference dependent preferences the total number of participants in an auction should affect bids in auctions for real objects but not in auctions with induced monetary values our findings are consistent with expectations based reference dependent preferences and loss aversion in real object auctions subjects bids are affected by the number of competitors and on average they decline with the intensity of competition in induced value auctions instead bids are unaffected by the intensity of competition we also successfully replicate an experiment from sprenger 2015 aimed at distinguishing expectations based loss aversion from models of disappointment aversion this provides additional evidence that our findings in the auction experiments are due to expectations based loss aversion

labor supply of new york city cabdrivers one day at a time life cycle models of labor supply predict a positive relationship between hours supplied and transitory changes in wages because such changes have virtually no effect on life cycle wealth previous attempts to test this hypothesis empirically with time series data have not been supportive estimated elasticities are typically negative or nonsignificant such analyses however are vulnerable to measurement error and other estimation problems we use data on daily observations of wages and hours for new york city cab drivers to estimate the supply response to transitory fluctuations in wages cab drivers decide daily how many hours to supply and face wages that are positively correlated within days but largely uncorrelated between days using these data our central finding is that wage elasticities are persistently negative from 5 to 1 in three different samples even after correcting for measurement error using instrumental variables these negative wage elasticities challenge the notion that cab drivers trade off labor and leisure at different points in time and question the empirical adequacy of life cycle formulations of labor supply

money stock targeting and money supply an intertemporal optimization approach with an application to canada we propose a model of the short term behaviour of the monetary authorities of a small open economy that is willing to stabilize to some extent its bilateral exchange rate vis a vis a dominant partner the optimal money supply strategy is derived using intertemporal optimization arguments in a rational expectations environment the model is formulated so as to avoid the time inconsistency problem stressed by kydland and prescott 1977 it allows econometric estimation of the optimal money supply rule as well as of the parameters of the intertemporal utility function and of the function that defines the intermediate target money stock the model is successfully estimated on canadian quarterly data using maximum likelihood techniques copyright 1988 john wiley sons ltd

endowments and risky choice abstract we report evidence of an endowment effect for risk extending previous results to the popular paired choice lottery setting specifically we observe a distribution of revealed preferences consistent with risk aversion that diminishes in endowed variance although the effect is considerably weaker for compound relative to simple lotteries we also find that in the absence of an obvious endowment subjects behave as if the comparatively lower variance lottery is a cognitive reference point revealing a distribution of preferences indistinguishable from subjects who are explicitly endowed with the low variance lottery finally we report no significant difference in elicited preferences between two popular mechanisms the multiple price list and a variant on the becker degroot and marshak mechanism when no endowment is induced suggesting previously reported differences in behavior between the two mechanisms may be in part a consequence of relative responsiveness to endowment framing

a critical review of distance function based economic research on china s marginal abatement cost of carbon dioxide emissions abstract the last few years have witnessed a rapidly emerging literature estimating the marginal abatement cost or the shadow price of carbon dioxide co2 emissions in china using parametric or non parametric distance function approaches this is largely driven by the fact that china has become the world s largest carbon emitter and thus faced mounting domestic and international pressure to mitigate emissions there is an urgent policy need to model and predict the cost burdens of various mitigation scenarios consistent information about the marginal abatement cost of co2 emissions plays a crucial role in addressing this need however the existing literature has suffered from various issues that have severely weakened the scientific support that these studies could potentially provide for sound policy making this paper provides a thorough and critical review of this rapidly emerging literature and identifies important research directions that need the most attention from scholars

dea environmental assessment on us petroleum industry non radial approach with translation invariance in time horizon abstract this study empirically assesses the performance of the petroleum industry focusing upon independent companies in the united states us for the empirical study we use the data envelopment analysis dea that has been widely used for environmental assessment and performance measurement the conventional use of dea requests that all observations in the data set should be positive prohibiting an occurrence of zero and or negative values the requirement of non negative value is inconsistent with the reality of us petroleum industry because many oil firms recently experience negative shocks in financial performance to overcome the obstacle this study discusses the property of translation invariance under undesirable congestion e g capacity limit in the transportation pipeline network and desirable congestion e g green technology innovation based on the non radial models the property implies that the unified efficiency measure should be not influenced even if production factors are shifted toward the same direction by adding or subtracting a specific real number the property makes it possible that we can evaluate the performance of firms whose production factors contain zero and or negative values this study is empirically concerned with practical implications of translation invariance from energy and environmental perspectives in addition this study examines the proposed environmental assessment in a time horizon for the purpose this study uses window analysis to examine an efficiency change along with a time shift our empirical investigation finds the following three implications first under the natural disposability the oil firms efficiency growth rates have become less than unity implying the industry wide difficulty or inability to cut back their drilling and production operations second all firms have been under regulatory and stakeholder pressures on air pollution therefore the efficiency growth rates under managerial disposability have not exhibited a major change during the observed annual periods finally such implications are statistically reconfirmed by regression analysis that examines how the change of energy price influences unified efficiencies under natural and managerial disposability an exception can be found in the natural disposability where energy prices influence their efficiency growths thus an increase in energy prices is important in maintaining a high level of efficiency growths in the us petroleum industry

willingness to pay and compensation demanded experimental evidence of an unexpected disparity in measures of value aside from possible income effects measures of the maximum amounts people will pay to avoid a loss and the minimum compensation necessary for them to accept it are generally assumed to be equivalent unexpectedly wide variations between these sums however have been noted in survey responses to hypothetical options this paper reports the results of a series of experiments that confronted people with actual money payments and cash compensations the results indicate that the compensation measure of value seems to exceed significantly the willingness to pay measure which would appear to call into some question various rules of entitlement damage assessments and interpretations of indifference curves

reference points and effort provision a key open question for theories of reference dependent preferences is what determines the reference point one candidate is expectations what people expect could affect how they feel about what actually occurs in a real effort experiment we manipulate the rational expectations of subjects and check whether this manipulation influences their effort provision we find that effort provision is significantly different between treatments in the way predicted by models of expectation based reference dependent preferences if expectations are high subjects work longer and earn more money than if expectations are low

social sustainability measured by intermediate approach for dea environmental assessment chinese regional planning for economic development and pollution prevention abstract this study examines the level of simultaneous achievement on economic prosperity and environmental protection so measuring the level of sustainability by a newly proposed intermediate approach conventionally dea data envelopment analysis for performance evaluation was used to assess various economic activities of organizations that utilized inputs e g the number of employees to yield desirable outputs e g the number of products the methodology was usually classified into radial or non radial category in an effort of extending it to environmental assessment dea needs to incorporate undesirable outputs e g the amount of co 2 into the computational framework this type of assessment is referred to as dea environmental assessment the proposed intermediate approach develops a new type of dea environmental assessment by combining the analytical features of radial approach with those of non radial approach the new approach measures the level of unified inefficiency on each production factor and determines the level of total unified inefficiency from the average of the sum of these inefficiency scores a rank sum test and a mean test are additionally incorporated into the proposed intermediate approach such a combination enhances the statistical capability as an application this study examines the level of sustainability related to 30 provinces in china from 2003 to 2014 the application finds four policy implications first it is important for china to allocate its resources to western provinces at a level that it has used for coastal developments second the government continues to reinforce the policy making effort on environmental protection by paying attention to central and southern regions the chinese industries need to transfer toward green energy the transfer should be efficiently executed for their future developments third the government has focused on the sustainability development in urban provinces and then has gradually shifted the policy influence toward rural areas finally the policy implementation needs a time lag until it becomes effective the time lag on economic policy is longer than that of environmental policy the economic policy has historically produced a regional imbalance often leading to educational and income imbalances among chinese provinces

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

do people anticipate loss aversion there is growing interest in the use of loss contracts that offer performance incentives as up front payments that employees can lose standard behavioral models predict a trade off in the use of loss contracts employees will work harder under loss contracts than under gain contracts but anticipating loss aversion they will prefer gain contracts to loss contracts in a series of experiments we test these predictions by measuring performance and preferences for payoff equivalent gain and loss contracts we find that people indeed work harder under loss than gain contracts as the theory predicts surprisingly rather than a preference for the gain contract we find that people actually prefer loss contracts in exploring mechanisms for our results we find suggestive evidence that people do anticipate loss aversion but select into loss contracts as a commitment device to improve performance using one bias loss aversion to address another dynamic inconsistency data as supplemental material are a
