an experimental investigation of the hahn noll revenue neutral auction for emissions licenses abstract this paper reports on three series of laboratory experiments designed to test the performance of the hahn noll revenue neutral auction rna an alternative institution a no rebate uniform price auction upa is also examined as a benchmark in these experiments the rna markets were little different from upa markets in terms of either prices or market efficiencies the two institutions did differ in terms of the distribution of the gains from exchange and of the propensity of bidders to engage in a certain type of overbidding

energy security in bangladesh perspective an assessment and implication energy is a key indicator of the nation s overall economic as well as social development looking at the present energy demand scenario in bangladesh electricity demand has significantly increased over the past years most of the bangladesh s power plants are heavily dependent on expensive imported fossil fuel energy resources thus the power failure has become an acute problem for the country and adversely affects the socio economic development of the country consequently the shortage and constraint in availability of fossil fuels appeal to boost up the renewable energy sector in bangladesh in order to bring down the gap between demand and supply hence decisive steps to reform the power sector with a mandate to oversee these sectors urgently need to overcome current energy crisis facing in the country in this paper efforts have been made to summarize the availability current status strategies perspectives promotion policies major achievements and future potential of energy options in bangladesh

a nonparametric cost approach to scale efficiency starting with farrell fieldhouse 1962 a host of notiparametric models have been developed for calculation of scale efficiency a common property of these models is that they are specified in terms of input output data duality theory has taught us that technological characteristics may be analyzed from either the primal or the dual cost side the purpose of this paper is to introduce a nonparametric dual method of calculating scale efficiency

barriers to energy efficiency a comparison across the german commercial and services sector abstract based on a large sample for the german commercial and services sector this paper econometrically assesses the relevance of various types of barriers to energy efficiency at the sectoral level and across fifteen sub sectors the results at the level of entire sectors suggest that the lack of information about energy consumption patterns and about energy efficiency measures lack of staff time priority setting within organizations and in particular the investor user dilemma are all relevant barriers allowing for sector specific differences in the relevance of these individual barriers yields a more heterogeneous picture the numbers and types of relevant barriers vary across sub sectors and the majority of sub sectors are subject to relatively few barriers the statistically most significant barriers are found for the sub sector of public administrations these findings are robust independent of whether the definition of an organization s energy efficiency performance includes only measures that have actually been realized or also those that are being planned for planned projects however organizations appear to underestimate internal priority setting as a barrier to energy efficiency

news a decision oriented model for new product analysis and forecasting modeling efforts in the area of new product introductions have had a significant impact on marketing planning and strategy one result of these efforts bbdo s new product early warning system news has been used since the late 1960s to provide marketing managers with forecasts and diagnostic information regarding their new product strategies this article presents the specification of the news model its parameter estimation methods and its validation a brief case history is also included which illustrates how the model is applied in a typical new product situation news is designed to use a variety of readily obtainable input data to generate forecasts of consumer awareness trial repeat purchase usage sales and market share for a new brand these outputs combined with diagnostics from the model can then be incorporated into the marketing plan in a way that will improve the new entry s chances of success in the marketplace the model can be used to project early test market data news market

attitudes toward risk and compliance in emission permit markets we investigate the effects of uncertainty and concomitant risk aversion as they impact the incentive structure and subsequent operation of an emissions permit market modeled after the u s s02 market our theoretical results suggest that uncertainty dulls incentives to achieve cost savings through permit trading and inhibits efficient allocation of abatement efforts by firms we test hypotheses in an experimental laboratory setting and find that the irreversibility of investment in abatement technology may present countervailing incentives for potential sellers of permits resulting in a wait and see attitude toward adoption of efficient levels of abatement technology

does the energy efficiency paradox exist technological progress and uncertainty we explain why firms may choose not to undertake investments inenergy saving technologies that appear profitable from a net presentvalue perspective as future technological advances are inherentlyuncertain and investments in new technology are at least partly irreversible it may pay to postpone investments in energy savingand wait for the arrival of improved varieties this insight casts doubton the existence of so called low hanging fruits in energy saving although we do not wish to deny that organisational failures may alsobe important failure to appreciate the underlying stochasticity oftechnological progress may obscure the insight that there is value inwaiting and costs involved in terminating the option to invest theappetite for low hanging fruits will be less when these costs areincorporated in the analysis we demonstrate that the effect of thearrival rate of new technologies on the adoption lag for a rational firmis ambiguous the same holds for the effect of the expected jump inefficiency of new technologies government policies aimed at enhancingthe adoption of new technologies through stimulation of r d maytherefore be counterproductive

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

market barriers to energy efficiency abstract discussions of energy policy in an environmentally constrained world often focus on the use of tax instruments to internalize the external effects of energy utilization or achieve specified reductions in energy use in the most cost effective manner a substantial literature suggests however that significant opportunities exist to reduce energy utilization by implementing technologies that are cost effective under prevailing economic conditions but that are not fully implemented by existing market institutions this paper examines the theory of the market for energy using equipment showing that problems of imperfect information and transaction costs may bias rational consumers to purchase devices that use more energy than those that would be selected by a well informed social planner guided by the criterion of economic efficiency consumers must base their purchase decisions on observed prices and expectations of post purchase equipment performance if it is difficult or costly for individuals to form accurate and precise expectations the level of energy efficiency achieved by competitive markets will vary from the socially efficient outcome such market barriers suggest a role for regulatory intervention to improve market performance at prevailing energy prices

beyond case studies barriers to energy efficiency in commerce and the services sector to assess the empirical relevance of various barriers to the diffusion of energy efficient measures we conduct econometric analyses for 19 sub sectors in the german commercial and services sectors results from estimating a separate logit model for each sub sector suggest that the most important barriers are the investor user dilemma and the lack of information about energy consumption patterns typically multiple types of barriers are found to be statistically significant but they vary considerably across sub sectors finally we discuss policy implications for the most relevant barriers

factors impacting investments in energy efficiency and clean technologies empirical evidence from slovenian manufacturing firms abstract promoting energy efficiency is one of the top priorities of the eu energy strategy manufacturing is identified there as one of the sectors holding the potential for substantial energy efficiency improvements this paper therefore examines factors impacting firms decisions to invest in energy efficiency and clean technologies drawing on the energy efficiency gap literature the impact of three groups of factors is analysed namely economic firm specific characteristics and market drivers organisational and regulatory employing probit and bivariate probit models on a panel data set for 848 slovenian manufacturing firms over 7 years 2005 2011 the paper finds that decisions to invest in energy efficiency and in clean technologies are impacted by similar yet not identical factors the following factors significantly increase the likelihood of both energy efficiency and clean technology investments share of energy costs market share and export orientation importantly other types of investments except for investments in the expansion of existing capacities do not crowd out energy efficiency or clean technology investments on the other hand foreign ownership and managers expectations of future demand only impact energy efficiency investments while clean technology investments are influenced by managers expectations of the future business condition of the firm further the economic and financial crisis reduces the likelihood of clean technology investments but not energy efficiency investments this is explained by the fact that investments in energy efficiency represent a cost effective solution for the firm the same argumentation can be used to explain why high energy costs also play an important role for investments in clean technology in addition the likelihood to invest is found to be importantly influenced by industry specific characteristics which captures the effect of industry differences in environmental regulation and other conditions the paper adds to the existing literature in three important ways it employs data on actual rather than intended investments it examines investment decisions over a number of years thereby allowing for an analysis of the impact of the recession on firms decisions and it examines relationships among different types of investments accounting for a potential crowding out effect based on the paper s findings it can be concluded that the energy efficiency gap is less likely to exist in large and well performing firms implying that policy measures should primarily target less energy intensive small and medium sized enterprises

the structure of technical efficiency it is common practice to decompose measures of efficiency into component measures of technical and allocative efficiency in this paper we show how and why to decompose a general measure of technical efficiency into component measures of purely technical efficiency congestion and scale efficiency and we investigate the properties of each measure we do so for a multiple output technology which satisfies a weak axiom system that does not include either constant returns to scale or strong input disposability

energy conservation investment do consumers discount the future correctly we argue that the apparently high discount rates attributed to investors making energy conservation investments are not irrational or the result of some market failure rather they may result from an investor recognizing that many conservation investments entail substantial sunk costs in the presence of these costs and uncertainty over future conservation savings consumers should use a higher hurdle rate for investment than if there were no uncertainty simulations suggest that the hurdle rate should be about four times greater than the standard rate an implication of our model is that tax subsidies for the purchase of conservation capital are likely to be ineffective we discuss alternative policy approaches which are more likely to increase energy efficient investment namely mandatory efficiency standards and energy taxes

global and local scale characteristics in convex and nonconvex nonparametric technologies a first empirical exploration the purpose of this contribution is to empirically implement and supplement the proposals made by podinovski 2004b to explore the nature of both global and local returns to scale in nonconvex nonparametric technologies in particular we both propose a simplified method to compute the global returns to scale and employ some secondary data sets to investigate the frequency of the special case of global sub constant returns to scale furthermore when determining global returns to scale using both convex and nonconvex technologies we verify how often the resulting information is concordant or conflicting finally besides comparing the fdh and dea evolution of ray average productivity for some typical individual observations we introduce in the literature two original methods for the determination of local returns to scale in nonconvex technologies

defensive marketing strategies this paper analyzes how a firm should adjust its marketing expenditures and its price to defend its position in an existing market from attack by a competitive new product our focus is to provide usable managerial recommendations on the strategy of response in particular we show that if products can be represented by their position in a multiattribute space consumers are heterogeneous and maximize utility and awareness advertising and distribution can be summarized by response functions then for the profit maximizing firm it is optimal to decrease awareness advertising it is optimal to decrease the distribution budget unless the new product can be kept out of the market a price increase may be optimal and even under the optimal strategy profits decrease as a result of the competitive new product furthermore if the consumer tastes are uniformly distributed across the spectrum a price decrease increases defensive profits it is optimal at the margin to improve product quality in the direction of the defending product s strength and it is optimal at the margin to reposition by advertising in the same direction in addition we provide practical procedures to estimate 1 the distribution of consumer tastes and 2 the position of the new product in perceptual space from sales data and knowledge of the percent of consumers who are aware of the new product and find it available competitive diagnostics such as the angle of attack are introduced to help the defending manager this article was originally published in marketing science volume 2 issue 4 pages 319 360 in 1983

the efficiency paradox bureaucratic and organizational barriers to profitable energy saving investments abstract the paradox of why profitable energy saving investments are not undertaken continues to provoke debate the underlying phenomenon might be called the efficiency paradox because it represents a case in which business firms which are often presumed or taken axiomatically to be economically efficient make decisions that do not maximize profits new data from one of the us environmental protection agency s voluntary pollution prevention programs enables this paradox to be explored statistically the data show that both the level and variation in returns to lighting upgrade investments cannot be explained by standard economic models substantial gains in energy efficiency can be achieved without sacrificing profitability both economic and organizational factors account for some of the variation in observed returns to these investments but the results suggest a need for improved and more comprehensive theories of the investment behavior of firms and other organizations

differences in perception how the experts look at energy efficiency findings from a finnish survey abstract using energy efficiently is generally considered to be essential for a continuing prosperous future as a result improving efficiency has become a focus of attention and recently a lot of time and effort has been expended to develop new energy efficiency methodologies and technologies considering the amount of focused attention the rate of improvement has not been encouraging human behaviour is an important factor of the energy efficiency challenge and research has revealed several consumer profiles with significantly different perceptions on energy issues in this study the focus is not on consumers but on energy efficiency professionals a number of finnish energy efficiency professionals from both the private and public sectors were surveyed revealing that experts have decidedly different perceptions regarding energy efficiency our analysis of survey results suggests that energy efficiency expertise comes from a variety of educational and professional backgrounds and that instead of working on common ground experts with differing perspectives are endeavouring to make progress in a complex and multifaceted arena focusing on specific areas in which players need to share a common understanding of terminology and where common and clearly stated goals can be established should result in an acceleration of efficiency improvement results

efficiency productivity and determinants of inefficiency at public day care centers in sweden efficiency differences among day care centers and productivity change over time are examined on the basis of nonparametric frontiers calculated using the dea methodology the data consist of approximately 200 public day care centers in gothenburg sweden for the years 1988 and 1989 the findings indicate a potential output increase of about 10 to 15 per cent each year and a productivity decrease of 3 per cent between the years an attempt is also made to explain the differences in inefficiency by applying a tobit model

dynamic efficiency measurement theory and application nonparametric dynamic measures of production efficiency are developed in the context of an adjustment cost technology and intertemporal cost minimization bounds on each efficiency measure are derived for each firm using a nonparametric revealed preference approach long run efficiency measures indicate the relative efficiency of both variable and dynamic factors while short run measures of efficiency indicate whether variable inputs are employed efficiently in the production process the efficiency measures are temporal in nature by describing the degree of efficiency of the firm at a particular point along its adjustment path the empirical implementation is illustrated for a balanced panel of pennsylvania dairy operators during 1986 1992

implied discount rate and payback threshold of energy efficiency investment in the industrial sector the industrial sector is responsible for about a third of the energy usage in the united states and there is significant energy saving potential from the industrial sector however the phenomenon of energy efficiency gap the scenario in which cost effective energy efficient technologies enjoy only limited market success appears frequently in the industrial sector this article tries to explain this efficiency gap in the industrial sector by empirically estimating the implied discount rates and payback thresholds industrial firms use to evaluate their energy efficiency investments using the industrial assessment centers iac database from 2002 to 2011 with more than 30 000 energy efficiency recommendations this article builds structural models of firms evaluation of an energy efficiency project the model results show that the implied discount rates of medium to small industrial firms range from 40 to 45 and the average payback threshold is about 9 months

5 information impact and allocation rules in auctions with affiliated private values a laboratory study in affiliated private value auctions each bidder has perfect information regarding his her own value for the object at auction but higher values of the item for one bidder make higher values for other bidders more likely we report on a series of experiments examining three key implications of these auctions i in a first price auction public information about rivals values increases expected revenue ii an english auction increases expected revenue compared to a first price auction and iii a second price auction is isomorphic to an english auction in examining these issues we compare predictions of some ad hoc bidding models with nash equilibrium predictions in the first price auction experiments nash equilibrium bidding theory organizes the data better than either of two ad hoc bidding models public information about others valuations does increase average revenue but the increase in revenue is smaller and less reliable than predicted under risk neutral nash equilibrium bidding lower average revenue might be attributed to risk aversion while the high variability is attributed to a sizable frequency of individual bidding errors relative to the theory bidding theory precisely organizes english auction outcomes after a brief initial learning period the dominant strategy equilibrium does not organize second price auctions nearly as well as market prices persistently exceed predicted prices the difference between english and second price outcomes is attributed to effects of different information flows inherent in the structure of the two institutions on eliminating bidding errors revenue impacts of these two institutions relative to a first price auction are examined in light of observed bidding patterns

technical and scale efficiency of japanese commerical banks a non parametric approach not only are the nature and extent and scale efficiency of japanese commerical banks studied but a relationship between both organizational status and size efficiency is also announced the efficiency measures are computed from a 1990 sample of cross sectional data for the estimation we employ the non parametric approach which has recently been gaining popularity for the studies of banking efficiency outside japan

dea duality on returns to scale rts in production and cost analyses an occurrence of multiple solutions and differences between production based and cost based rts estimates this article discusses the concept of rts returns to scale in the framework of dea data envelopment analysis production and cost analyses focusing on an occurrence of multiple solutions and how to deal with such a difficulty dual relationships between production based and cost based rts estimates are also theoretically discussed in this study

static efficiency decompositions and capacity utilisation integrating economic and technical capacity notions starting from existing static decompositions of overall economic efficiency on nonparametric production and cost frontiers this article proposes more comprehensive decompositions including several cost based notions of capacity utilization furthermore in case prices are lacking we develop additional decompositions of overall technical efficiency integrating a technical concept of capacity utilization these new efficiency decompositions provide a link between short and long run economic analysis and in empirical work avoid conflating inefficiency and differences in capacity utilization an empirical analysis using a monthly panel of chilean hydro electric power plants illustrates the potential of these decomposition proposals

barriers to electricity load shift in companies a survey based exploration of the end user perspective abstract as countries move toward larger shares of renewable electricity the slow diffusion of active electricity load management should concern energy policy makers and users alike active load management can increase capacity factors and thereby reduce the need for new capacity improve reliability and lower electricity prices this paper conceptually and empirically explores barriers to load shift in industry from an end user perspective an online survey based on a taxonomy of barriers developed in the realm of energy efficiency was carried out among manufacturing sites in mostly southern germany findings suggest that the most important barriers are risk of disruption of operations impact on product quality and uncertainty about cost savings of little concern are access to capital lack of employee skills and data security statistical tests suggest that companies for which electricity has higher strategic value rate financial and regulatory risk higher than smaller ones companies with a continuous production process report lower barrier scores than companies using batch or just in time production a principal component analysis clusters the barriers and multivariate analysis with the factor scores confirms the prominence of technical risk as a barrier to load shift the results provide guidance for policy making and future empirical studies

adoption of low cost energy efficiency measures in the tertiary sector an empirical analysis based on energy survey data this paper empirically explores factors driving the adoption of low cost energy efficiency measures in the tertiary sector which mainly consists of public and private services trade commerce and some small industries the measures considered include switching off installations or lighting managing energy use and routinely considering energy efficiency for new purchases our statistical analysis employs single and multivariate probit models relying on more than 1500 observations from a recent representative survey of the tertiary sector in germany the findings suggest that the landlord tenant dilemma holds for the adoption of all low cost energy efficiency measures considered they further imply that financial incentives such as higher energy prices accelerate the diffusion of low cost energy measures our findings also provide some evidence that knowledge transfer from the mother company to a subsidiary enhances the diffusion of low cost energy efficiency measures likewise public sector organizations are more likely to adopt energy management by and large though sectoral heterogeneity appears to have little impact on the adoption of low cost energy efficiency measures

cost efficiency of electric grid utilities in china a comparison of estimates from sfa mle sfa bayes and stoned cnls with the purpose of estimating the range of cost efficiency levels of the power grid sector in china we assembled a data set including 23 provincial power grid companies spanning from 2005 to 2009 and conducted an empirical study based on the sfa mle sfa bayes and stoned cnls methodologies empirical results show that the average values of efficiency from different models vary from 0 85 to 0 92 depending especially on the assumptions underlying inefficiency content further results demonstrate that there is exogenous technical progress during the sample period and per capita gdp of the province is negatively related to the costs of the electric grid company located in the corresponding province we hope this empirical study will contribute to the debate on an efficiency based regulation scheme which was introduced to the chinese electric grid sector on a pilot base in 2014

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

how high are option values in energy efficiency investments high implicit discount rates in consumers energy efficiency investments have long been a source of controversy in several recent papers hassett and metcalf argue that the uncertainty and irreversibility attendant to such investments and the resulting option value account for this anomalously high implicit discounting using their model and data we show that to the contrary their analysis falls well short of providing an explanation of this pattern

evaluating the performance of higher education institutions in europe a nonparametric efficiency analysis of 944 institutions abstractalthough a long tradition exists of studying the economics of education performance comparisons of different kinds have traditionally been difficult to undertake an important impediment has been the lack of comparable data to a large extent this study remedies the shortcomings of earlier studies our contribution is twofold first the current higher education policy of contraction and economizing common to most european countries make knowledge of potential efficiency gains crucial second a unique database allows us to study a broad diversity of organizations as well as organizations located in a number of different european countries the study suggests evaluating higher education institution hei performance in a production theory context applying the well known data envelopment analysis dea method to a cross section of 944 heis in 17 european countries the dea approach is particularly suitable in this context where little is known about production technologies and economic behavio

auction institutional design theory and behavior of simultaneous multiple unit generalizations of the dutch and english auctions historically english and dutch auctions have been used for the exchange of single objects such as works of art or single lots of a good such as produce fish or cut flowers where these institutions have been used for the exchange of multiple units such as the australian wool auction using english rules successive lots of the good are sometimes sold sequentially at auction in some but not all instances this is because the goods are not identical even though the various lots may be close substitutes see penny burns 1985 where the goods are accepted universally as being homogeneous as in the securities markets multiple units are often commonly auctioned simultaneously in the securities industry orders are batched for simultaneous execution in multiple unit auctions in what are referred to as call markets that is the security is called for auction at a particular point in time this type of market is used on the stock exchanges of austria belgium france germany and israel some of these are verbal and some are sealed bid auctions although the u s organized exchanges are predominantly continuous rather than call markets except that call markets are used each day to open trading in each listed security there is a growing number of exceptions such as the proliferation since 1984 of auction preferred stock goldman sachs and co october 1984 and money market preferred stock lehman brothers july 1984 we now have dutch auction rate transferable securities called darts stated rate auction preferred stock or straps and many more after the initial subscription offering of this type of security the market is called every 49 days to reset the preferred dividend rate using a multiple unit auction the exchange of shares and the dividend determination is based on the array of stated dividend rates at which existing holders and potential new holders are willing to sell and or buy corresponding quantities the dividend rate and exchange of shares every 49 days is executed using the uniform price or competitive sealed bid mechanism vernon l smith et al 1980 the discussion to follow will be confined to this sealed bid form of the call market call markets provide temporal consolidation of trade orders or other forms of expressing the desire to buy and sell by comparison with continuous trading call markets offer both advantages and disadvantages robert a schwartz 1988 pp 442 6 the cited advantages include low cost of operating the exchange information aggregation and presumed pricing efficiency price stability individual trades which are thought to have a small impact on price reduced price uncertainty and finally nondiscriminatory pricing however there are offsetting disadvantages 1 the market is inaccessible except at the time of call 2 no bid offer contract or price information is available until the results of the call are announced and 3 there is transaction uncertainty because a submitted bid offer may be too low high to execute inside the supply demand cross these conditions are only partially alleviated if there is a secondary market between calls these disadvantages may be significant in september 1988 the wall street journal published an article on the failure of a call market for the auction rate preferred stock economic science laboratory university of arizona tucson arizona this material is based upon work supported by the national science foundation under grant no ses 8320121

regional concentration and efficiency in mexican manufacturing abstract this paper explores the link between industrial location concentration and economic efficiency in mexican manufacturing using a linear programming approach the authors calculate indices of overall technical allocative and scale efficiency for mexican manufacturing industries by state to test whether in 1985 those regions with high levels of industrial concentration were suffering from the costs of congestion the evidence suggests that at least at the aggregate level there continued to be a positive relationship between industry concentration and efficiency in production there is also evidence that overall efficiency was related to scale efficiency although highly industrialized regions on the production frontier often operated at inefficient scales in particular the most concentrated regions the federal district the state of mexico jalisco and nuevo leon consistently display decreasing returns to scale indicating that the process of industrial concentration may be leading to diseconomies of scale finally an econometric analysis suggests that scale urbanization and agglomeration economies are positively related to overall and technical efficiency at the regional level while foreign ownership is negatively related agglomeration economies at the industry level were not significant the paper also makes a methodological contribution it is the first application of a distance function production methodology to measuring regional efficiency in a developing country it demonstrates how to conduct distance function efficiency analysis using the newly developed gams mathematical programming environment these tools should be of considerable interest to applied microeconomists

measuring and explaining scale efficiency with the parametric approach the case of greek tobacco growers estimates of technical and scale inefficiencies of tobacco farms in greece during the period 1991 1995 are obtained by using the parametric approach the degree of technical efficiency was found to be lower than the degree of scale efficiency and thus a greater portion of overall inefficiency is due to producing below the production frontier than to producing at an inefficient scale in addition the vast majority of farms in the sample exhibited suboptimal scale implying that output should be expanded to reach the optimal scale empirical results are provided to determine the impact of various socioeconomic demographic and geoclimatic indicators on technical and scale efficiency

barriers to increasing energy efficiency evidence from small and medium sized enterprises in china abstract this paper analyzes financial informational and organizational barriers to energy efficiency investments for small and medium sized enterprises smes in china its findings are based on a survey of 480 smes in zhejiang province and complemented by semi structured interviews with enterprises contained in the survey sample responses reveal that only a minority of smes in china actively perform energy saving activities at a significant level the survey data suggest further that informational barriers are the core bottleneck inhibiting energy efficiency improvements in china s sme sector financial and organizational barriers also influence a company s energy saving activities with interview based evidence stronger than statistical evidence the interviews point out three additional barriers to energy saving activities the role of family ownership structures lax enforcement of government regulations and the absence of government support as well as a lack of skilled labor more than 40 of enterprises in the sample declared themselves unaware of energy saving equipment or practices in their respective business area indicating that there are high transaction costs for smes to gather assess and apply information about energy saving potentials and relevant technologies one policy implication of the study is that the chinese government could play a more active role in fostering the dissemination of energy efficiency related information in the sme sector

returns to scale in convex production technologies the notion of returns to scale rts is well established in data envelopment analysis dea in the variable returns to scale production technology the rts characterization is closely related to other scale characteristics such as the scale elasticity most productive scale size mpss and global rts types indicative of the direction to mpss in recent years a number of alternative production technologies have been developed in the dea literature most of these technologies are polyhedral and hence are closed and convex sets examples include technologies with weakly disposable undesirable outputs models with weight restrictions and production trade offs technologies that include several component production processes and network dea models for most of these technologies the relationship between rts and other scale characteristics has remained unexplored the theoretical results obtained in this paper establish such relationships for a very large class of closed convex technologies of which polyhedral technologies are an important example

semi radial technical efficiency measurement semi radial efficiency measurement combines technical efficiency as captured by the classical farrell measure with an economically meaningful mix efficiency component the semi radial evaluation we propose proceeds in two steps first we build on the price interpretation of the generally accepted koopmans efficiency notion to characterize appropriate benchmarks next we present both a quantity based distance measure and its dual price based equivalent to evaluate the mix efficiency factor the type of measures we propose may e g be used to provide a price rationale for the zieschang technical efficiency evaluation procedure

the role of the reference technology in measuring productive efficiency after a twenty year lull the measurement of productive efficiency is enjoying a revival in particular the index of efficiency developed by debreu i95i and later utilised by farrell i957 has received considerable attention these measures have been used fairly extensively in empirical work in both the operations research and economic literature these types of indexes have also appeared in the growing literature on testing for regularity conditions in production e g in afriat i972 diewert and parkan i983 and varian 1984 since the farrell type measure is the focus in this paper a brief review is useful in the farrell framework overall efficiency oe can be decomposed into two multiplicative components allocative efficiency ae and technical efficiency te

triggers and barriers to energy efficiency measures in the ceramic cement and lime sectors evaluating and understanding the interplay of barriers to the diffusion of energy efficiency measures is highly relevant because if policies are effective in overcoming these barriers co2 emissions can be decreased at low cost the study aims to understand how managers make decisions to invest in energy efficiency how perceived barriers affect these decisions and how policy can overcome these barriers we apply neo classical economic theory as well as insights from transaction cost economics and behavioural economics to understand why hurdle rates even when omitted costs and risk are taken into account are higher than the weighted average cost of capital we find that internal capital budgeting rules and the effort of studying technical feasibility and profitability are relevant to understanding the efficiency gap the results indicate that the voluntary agreement and the emission trading scheme are complementary addressing different barriers in different contexts

alternative treatments of congestion in dea a rejoinder to cooper gu and li abstract this paper is a response to cooper w w b gu and s li comparisons and evaluations of alternative approaches to the treatment of congestion in dea european journal of operational research this issue who claim that the standard fgl procedure by fare grosskopf and lovell for dealing with congestion in dea can i fail to identify congestion when it is present and ii identify congestion when it is not present we clarify the notion of congestion and its relationship to structural efficiency and free disposability respectively to point out that the fgl approach was originally intended for measuring structural efficiency i e the influence of congestion on the efficiency of a particular production unit not for identifying occurrence of congestion in any feasible production vector moreover we point out that the result of cooper et al partially arises from ignorance of some key maintained assumptions underlying the fgl approach further we present some counter examples which demonstrate that the alternative approach advocated by cooper et al can equally fail in identification of congestion finally some remarks on the influence of sampling error and errors in variables on the two stage dea approaches are presented

making the link climate policy and the reform of the uk construction industry this paper explores the barriers to energy efficiency in the construction of non domestic buildings in the uk the source of the barriers is argued to lie in the organisation of the construction industry including the linear design process the reliance on cost based competitive tendering and the incentives placed upon different actors the consequences include oversizing of equipment reduced quality neglect of whole life costs and lack of integrated design each of these problems can usefully be interpreted using concepts from the new institutional economics while the barriers are well known to construction industry specialists they are relatively neglected in the academic literature on energy policy furthermore conventional policy measures such as building regulations leave these barriers largely untouched the uk construction industry is currently undergoing a series of reforms which aim to change the relationship between different actors and to achieve improvements in product quality and productivity while these reforms have the potential to address many of the barriers the reform agenda makes practically no reference to sustainability this paper argues that climate policy objectives must be integrated into the reform agenda if the uk is to begin the transition to a low carbon built environment

the energy efficiency gap what does it mean abstract as renewed attention has been given by policy makers to energy conservation issues it has frequently been asserted that an energy efficiency gap exists between actual and optimal energy use the critical questions is how to define the optimal level of energy efficiency this paper seeks to disentangle some confusing strands of argument that are frequently brought to bear on this question by identifying the major conceptual issues that determine the set of feasible answers we identify five separate and distinct notions of optimality the economists economic potential the technologists economic potential hypothetical potential the narrow social optimum and the true social optimum each of these has associated with it a corresponding definition of the energy efficiency gap our analysis demonstrates that necessary preconditions for identifying the right measure of the energy efficiency gap include understanding and disentangling market failure and non market failure explanations for the gradual diffusion of energy efficient technologies

the impact of electricity demand reduction policies on the eu ets modelling electricity and carbon prices and the effect on industrial competitiveness the european electricity market is linked to a carbon market with a fixed cap that limits greenhouse gas emissions at the same time a number of energy efficiency policy instruments in the eu aim at reducing the electricity consumption this article explores the interactions between the eu s carbon market on the one hand and instruments specifically targeted towards energy end use efficiency on the other hand our theoretical analysis shows how electricity demand reduction triggered by energy efficiency policy instruments affects the emission trading scheme without adjustments of the fixed cap decreasing electricity demand relative to business as usual reduces the carbon price without reducing total emissions with lower carbon prices costly low emission processes will be substituted by cheaper high emitting processes possible electricity and carbon price effects of electricity demand reduction scenarios under various carbon caps are quantified with a long term electricity market simulation model the results show that electricity efficiency policies allow for a significant reduction of the carbon cap compared to the 2005 emission level 30 emission reductions can be achieved by 2020 within the emission trading scheme with similar or even lower costs for the industrial sector than were expected when the cap was initially set for a 21 emission reduction

barriers to energy efficiency in industrial bottom up energy demand models a review the goal of this paper is to review bottom up models for industrial energy demand with a particular focus on their capability to model barriers to the adoption of energy efficient technologies the integration of barriers into the models is an important prerequisite for a more detailed and realistic modeling of policies for energy efficiency particularly with the emergence of more and more varying policy instruments it also becomes crucial for the models to take account of these policies as well as the barriers they address in a more realistic way our review revealed that despite the broadly evident existence of market failures and barriers for energy efficient technologies they are only partly and in a rather aggregated form considered in today s bottom up models the state of the art bottom up model is based on an explicit representation of the technology stock and considers the costs of energy efficiency options in detail but with regard to barriers most models only make use of an aggregated approach like an adjusted discount rate while some models do not even consider technology costs and energy prices but instead use exogenous technology diffusion rates other more advanced models took first steps towards considering barriers in more detail the latter allows differentiation between multiple parameters that influence technology adoption still even in the most advanced models only a few of the observed barriers are explicitly considered at the same time new approaches to considering barriers like uncertainty or the slow spread of information are being developed in other disciplines we conclude the paper by summarizing promising ways to improve representation of barriers in bottom up models

theory and misbehavior of first price auctions recent experimental evidence appears to reject simple nash equilibrium models of bidding behavior in first price auctions the author presents a methodological critique of this evidence existing tests have concentrated on deviations of subjects from predictions in the message space of the action bid deviations the author suggests that it is more natural to evaluate subject behavior in expected payoff space he concludes that the evidence against the simple models is not significant enough to warrant their rejection copyright 1989 by american economic association
