green spillovers of outward foreign direct investment on home countries evidence from china s province level data abstract in recent years there has been substantial outward foreign direct investment ofdi from china to other countries meanwhile china has taken green development as one of its core future strategies questions arise as to whether the ofdi of china brings green spillovers towards home and should the government encourage ofdi to further promote the domestic green economy to answer these questions this study examines empirically the reverse spillovers of china s ofdi on its domestic green development based on a panel dataset involving 30 provinces provincial green total factor productivity gtfp is calculated and its relationship with ofdi is discussed for the period of 2006 2015 then the main results demonstrate whether china s ofdi has green spillovers on the domestic economy and to what extent they depend on provincial heterogeneity in terms of absorptive capability and environmental regulation stringency at the national level it is only either when employees in every province have more than 12 years of schooling on average or the environmental legal construction index reaches approximately 611 that china s ofdi can generate significant spillovers towards its green economic growth such that a rise of 1 unit of ofdi is associated with 2 4 and 3 2 increases in gtfp respectively moreover green benefits from ofdi cannot be found in the home country unless the stock of ofdi reaches a certain level i e beyond approximately 3361 chinese yuan rmb per capita at the 2005 constant price at the provincial level the influence of ofdi on the green economy in the eastern provinces is greater than that in other provinces additionally this study finds that the relationships between ofdi absorptive capability environmental regulation stringency and green economic growth are robust to multiple econometric methods and alternative proxies for threshold variables overall it is indicated that china s ofdi does bring green spillovers to china but the current effects show large heterogeneities across provinces and are still very limited due to the lack of necessary supporting conditions even with the dramatically rising scale ofdi in most of chinese provinces has only small effects on local transition to the green economy calling for the formulation of proper policies to encourage ofdi and enhance its green spillover effect

industry and country effects on managers perceptions of environmental uncertainties international management research highlights political government policy and macroeconomic uncertainties strategy studies focus on input supply product market and competitive uncertainties this study develops and tests the reliability of an instrument for measuring managers uncertainly perceptions data analyses using an international sample provide insights into the relative importance of country and industry factors for explaining managers perceptions of different environmental uncertainties

a modified malmquist luenberger productivity index assessing environmental productivity performance in china abstract the malmquist luenberger m l index has been used to assess environmental productivity growth with undesirable outputs through applying directional distance function ddf to standard malmquist productivity measurement however when calculating the cross period ddfs the m l index has the same infeasibility problem as the malmquist index does to address this infeasibility problem this paper discusses when infeasibility may happen and develops a modified m l index that is based on a new ddf we propose that the modified m l index can be applied to assessing environmental performance at both macro and micro levels at a macro level we evaluate china s growth in total factor productivity tfp from 1999 to 2012 accounting for undesirable impacts the results show that technical change is the main driver of most tfp growth the tfp changes support the status quo of a distinct gap in economic development among different regions at a micro level we assess chinese auto manufacturers environmental performance from 2005 to 2012 the results suggest that chinese automakers have enjoyed a noticeable tfp improvement and that technical change is the major contributor as well taking together reducing air emissions and other pollutants is an effective way of improving environmental productivity as demonstrated the proposed modified m l index has proved to be consistently feasible and guarantees non negative reference targets for all metrics as a result we recommend the modified m l index as a robust tool for solving the infeasibility problem that is typical in conventional index and for assessing productivity under environmental impacts

privatization in latin america lessons for transitional europe abstract latin american economies are predominately private with functioning financial systems substantial purchasing power and widespread understanding of how markets work nevertheless transitional and latin american privatizers share similar problems poor performing state firms varied commitment to privatization technical difficulties and adverse macroeconomic conditions five lessons from latin america are particularly relevant for transitional economies a privatization can help foster competition b governments can build competent institutions for privatization despite weak capacity c labor can benefit without majority control d transparency and share distributions help win public support and e selling profitable efficient firms can benefit the economy

a non radial dea approach to measuring environmental performance data envelopment analysis dea has gained great popularity in environmental performance measurement because it can provide a synthetic standardized environmental performance index when pollutants are suitably incorporated into the traditional dea framework past studies about the application of dea to environmental performance measurement often follow the concept of radial efficiency measures in this paper we present a non radial dea approach to measuring environmental performance which consists of a non radial dea based model for multilateral environmental performance comparisons and a non radial malmquist environmental performance index for modeling the change of environmental performance over time a case study of oecd countries using the proposed non radial dea approach is also presented it is found that the environmental performance of oecd countries as a whole has been improved from 1995 to 1997

assessing regional environmental efficiency in china with distinguishing weak and strong disposability of undesirable outputs abstract china has developed a remarkable economic growth in the past 30 years by accompanying with undesirable outputs the assumptions of weak and strong of undesirable outputs have become the focus discussion in data envelopment analysis dea models to have a comprehensive environmental efficiency measurement this paper proposes three dea models considering weak disposability strong disposability and distinguishing weak and strong disposability of undesirable outputs respectively we further combine with the malmquist luenberger productivity index to assess the environmental efficiency and the dynamic change trend of 30 provinces in china from 2005 to 2014 the results show that distinguishing technical features of undesirable outputs makes a significant difference to final environmental efficiency score at different regions the environmental efficiency of the whole nation however does not show any increasing trend during the ten years enhancing environmental efficiency of central and west area is an urgent task for chinese government the change trend of malmquist luenberger productivity index and technological change shows a similar shape technical progress is the main driving force to enhance the environmental efficiency relevant suggestions are presented for improving the regional environmental efficiency in china in the future

directional shadow price estimation of co2 so2 and nox in the united states coal power industry 1990 2010 abstract shadow prices also termed marginal abatement costs provide valuable guidelines to support environmental regulatory policies for co 2 so 2 and no x the key contributors to climate change this paper complements the existing models and describes a directional marginal productivity dmp approach to estimate directional shadow prices dsps which present substitutability among three emissions and are jointly estimated we apply the method to a case study of co 2 so 2 and no x produced by coal power plants operating between 1990 and 2010 in the united states we find that dsp shows 1 1 times the maximal shadow prices estimated in the current literature we conclude that estimating the shadow prices of each by product separately may lead to an overestimation of the marginal productivity and an underestimation of the shadow prices

nonparametric production technologies with weakly disposable inputs abstract in models of production theory and efficiency analysis the inputs and outputs are assumed to satisfy some form of disposability in this paper we consider the assumption of weak input disposability it states that any activity remains feasible if its inputs are simultaneously scaled up in the same proportion as suggested in the literature the shephard technology incorporating weak input disposability could be used to evaluate the effect of input congestion we show that the shephard technology is not convex and therefore introduces bias in evaluation of congestion to address this we develop an alternative convex technology whose use in the evaluation of congestion removes the noted bias we undertake a further axiomatic investigation and obtain a range of production technologies all of which exhibit weak input disposability but are based on different progressively relaxed convexity assumptions apart from the evaluation of input congestion such technologies should also be useful in applications in which some inputs are closely related or are overlapping and therefore satisfy only the weak input disposability assumption incorporated in the new models

learning to carry the cat by the tail firm experience disasters and multinational subsidiary entry and expansion we investigate whether firm experience with discontinuous risks particularly high impact disasters that are episodic and difficult to anticipate moderates the relationship between disasters foreign entry and expansion decisions using a panel data set with 57 500 observations from 106 large european multinational corporations and their subsidiaries operating across 109 countries from 2001 to 2007 we find that although discontinuous risk was negatively related to firm entry and expansion firms that had experience with high impact disasters were more likely to expand in countries experiencing disasters

foreign entry cultural barriers and learning this paper examines the longevity of foreign entries hypotheses are developed on the mode start ups vs acquisitions and ownership structure wholly owned vs joint ventures in relation to cultural distance the hypotheses are tested within a framework of organizational learning using data on 225 entries that 13 dutch firms carried out from 1966 onwards results show that the presence of cultural barriers punctuates an organization s learning cultural distance is a prominent factor in foreign entry whenever this involves another firm requiring the firm to engage in double layered acculturation we also identify locational paths of learning the longevity of acquisitions is positively influenced by prior entries of the firm in the same country similarly the longevity of foreign entries in which the firm has a majority stake improves whenever the expanding firm engaged in prior entries in the same country and in other countries in the same cultural block

mixed strategy nash equilibrium in data envelopment analysis abstract in a typical productivity analysis the efficiency measure assumes a perfectly competitive market with an endogenous price and depends on a fixed orientation with respect to a specific firm such as an input oriented measure when an imperfectly competitive market affects the endogenous price however firms may take a mixed strategy approach to address uncertain competition this study proposes a mixed strategy measure msm we construct a model embedded with a data envelopment analysis dea framework that identifies the mixed strategy nash equilibrium in the first stage and considers a probabilistic and multi oriented efficiency measure in the second stage based on the environmental regulation and a typical nash measure we create two indices environmental consistency and strategic consistency to support the business roadmap development we validate the proposed msm with an empirical study of china s electric power industry the results find that the proposed msm complements the nash measure and the msm model successfully supports our two managerial strategies invest in capacity expansion or develop emission abatement technology

nonparametric productivity analysis with undesirable outputs reply hailu and veeman 2001 henceforth hv use both primal nonparametric dea and dual nonparametric frontiers that include undesirable outputs the dual frontier provides the tightest nonparametric outer bound to the unknown underlying technology while the dea frontier provides the tightest innerbound to the technology varian banker and maindiratta chavas and cox all previous nonparametric analyses incorporating undesirable outputs had been based on the dea model and hv highlighted the limitations of this one sided approach by confronting the results from the dea model with those from the dual model the dea model was found to be very poor in terms of discriminating between observations as indicated in hv this is a problem that has also been noted by several other researchers in the conventional productivity literature before i provide specific responses to some of the comments by fare and grosskopf fg i would like to make the following general remarks first hv use input based measures and a variable returns to scale formulation of the dea model however fg support their arguments using output possibility frontiers output based measures and constant returnsto scaleassumptionsthatwerenotusedinhv it is well known that a dea model with constant returns to scale has different characteristics and provides different results compared to those with variable returns second and more importantly it should be noted that the dea model with constant returns to scale does not qualify as the inner nonparametric bound that is the subject of hv s article third the major difference between the weakly disposable and hv dea frontiers becomes irrelevant for measures of efficiency that explicitly penalize extrabadoutput infg sfigure1 forexample the area east of line bc is irrelevant in the hv

a framework for integrated risk management in international business treatments of risk in the international management literature largely focus on particular uncertainties to the exclusion of other interrelated uncertainties this paper develops a framework for categorizing the uncertainties faced by firms operating internationally and outlines both financial and strategic corporate risk management responses

shadow pricing of undesirable outputs in nonparametric analysis abstract for three decades a growing interest in the modeling of desirable and undesirable outputs has led to a theoretical and methodological debate in the nonparametric literature on production technology and efficiency the first main discussion is about the way of modeling bad undesirables as inputs or outputs or by transformation functions the second debate concerns the implications of the weak disposability assumption in the modeling of bad outputs in particular the possibility of assigning unexpected signs to shadow prices of bad outputs in addition we point out a current error in the modeling of weak disposability under a variable returns to scale technology in this paper we introduce a hybrid model to ensure the economically meaningful jointness of good and bad outputs while constraining shadow prices of bad outputs to their expected sign we argue that it is a sound compromise to model undesirable outputs with a meaningful primal dual economic interpretation finally we propose an extension to define shadow prices for undesirable outputs following the law of one price loop rule

exploring the green total factor productivity of china s metallurgical industry under carbon tax a perspective on factor substitution abstract the characteristics of high emissions and high energy consumption in metallurgical industry have brought great challenges to the green and low carbon transition in china as a low carbon economic instrument carbon tax is generally considered to be an effective way to reduce co2 emissions through raising energy cost but whether it will promote the green total factor productivity gtfp of china s metallurgical industry is still unanswered under this background this paper uses provincial panel data over years 2000 2015 to investigate the impact of carbon taxation on gtfp of metallurgical industry from the perspective of inter fuel and inter factor substitution the lock in mechanism is also incorporated in the three stage estimation model to better reflect the asymmetric price response of factors and fuels the results reveal that the slow marketization process of energy price and the rigid demand for energy in china s metallurgical industry hinder the substitution effect of energy the implementation of carbon tax has limited effect on energy saving and co2 reduction in the metallurgical industry of china and levying a carbon tax has a negative effect on gtfp during the research period therefore the government should not achieve co2 reduction targets at the expense of green economic growth gtfp is suggested to be considered in future assessment criteria in the process of transforming to low carbon economy

optimal path for controlling co2 emissions in china a perspective of efficiency analysis this paper examines the optimal control of co2 emissions from a perspective of efficiency analysis several centralized data envelopment analysis dea models are introduced to study the optimal allocation of co2 emissions under spatial temporal and spatial temporal allocation strategies respectively the models have been used to determine the optimal paths for controlling co2 emissions at provincial and regional levels in china a sensitivity analysis of the optimal path on the emission control coefficient under spatial temporal allocation strategy is further carried out our empirical results show that more developed regions should take emission reduction responsibility earlier than less developed regions in china of the three allocation strategies spatial temporal allocation strategy seems to be a better choice for achieving the optimal control of co2 emissions at country level since it is more encompassing by allowing both timing and spatial substitutions it is also found that there exists an inverted u shape relationship between the aggregate optimal gdp and the emission control coefficient which shows that modest emission reduction policy might be more appropriate for china in order to achieve the joint goals of economic development and co2 emission reduction

industrial eco efficiency in china a provincial quantification using three stage data envelopment analysis abstract the coordinated development of industrialization and the ecological environment is vital to achieve ecological civilization in china integratively considering the economy energy and resources and environment this study aims to measure the industrial eco efficiency of 30 provinces autonomous regions and municipalities in china between 2005 and 2013 a three stage data envelopment analysis dea modeling approach is adopted to eliminate interference of the external environment and statistical noise with industrial eco efficiency measurement the results show that regional industrial eco efficiency in china is affected by the factors of the environmental regulation technological innovation level of economic development and industrial structure after eliminating the impacts of external environment and statistical noise china s national average industrial eco efficiency declines by 30 between 2005 and 2013 the industrial eco efficiency of the 30 provinces increases but at different rates of growth the variation of overall regional industrial eco efficiency is primarily caused by scale efficiency furthermore all the 30 provinces are classified into four groups to interpret the causes of variation and differences of regional industrial eco efficiency in general the management and technology level and the economy of scale of industries should be improved simultaneously even though specific opportunities for industrial eco efficiency improvement vary across provinces in china

the eco efficiency of pulp and paper industry in china an assessment based on slacks based measure and malmquist luenberger index abstract china has become the world largest paper and paperboard producer however pulp and paper industry has involved high resource consumption and severe pollution especially for water this research has assessed the eco efficiency of china s pulp and paper industry at the national level and provincial level an overview regarding the cleaner production of china s pulp and paper industry was presented to reveal the measures for reducing environmental impact in the last two decades slacks based measure was used to analyze the efficiency levels of 16 provinces pulp and paper industries to uncover the underlying causes of eco efficiency performance malmquist luenberger index was calculated to discover the drivers of productivity growth of pulp and paper industries our results showed that the pollution treatment of china s pulp and paper industry has made progress in terms of water consumption and water pollution although the absolute amount of pollution discharge is still large chemical oxygen demand emissions are still the first critical influencing factor of pulp and paper industry s inefficiency furthermore efficiency progress was the dominating contribution of the industry s productivity growth between 2010 and 2013 the policies for adjusting the industrial structure of pulp and paper industry have resulted in the scale effects through eliminating backward production capacity and accelerating merger and acquisitions moreover the productivity of pulp and paper industry was underestimated when the undesirable outputs were ignored it indicates that the stricter environmental regulations have positive effects on paper companies to internalize environmental pressures in the production activities through environmental management in the future pulp and paper companies should further internalize the cost of pollution treatment through scale effects and technology improvement

crisis and competition in expert organizational decision making credit rating agencies and their response to turbulence in emerging economies firms often delegate elements of strategic decisions to outside experts who promise objective assessments which are especially valuable in unstable environments however experts themselves may be prone to skewed decision making as the stability of their own industry environment changes and as their positioning within the industry shifts we examine this possibility in the context of expert credit rating agencies agencies and their risk ratings of emerging market sovereign borrowers ratings published from 1987 to 1998 a period that includes both industry stability 1987 1996 and industry turbulence set off by financial crises in several emerging market countries 1997 1998 after controlling for macroeconomic and related objective risk factors linked to the sovereigns themselves we find several points 1 agency ratings during crisis induced industry turbulence are negatively skewed indicating undue pessimism among these experts in line with decision making perspectives predicting negative reaction by experts in an effort to retain legitimacy with salient stakeholders in this case investors and public regulators 2 this negative shift is greater for incumbent firms and regionally focused firms possibly because of the loss of previous informational advantages and 3 this negative shift during crisis induced turbulence is greater as industry rivalry among these experts increases in particular market segments possibly indicating the development of competitive bandwagons among experts together our results suggest that objective assessments by expert organizations are vulnerable to substantial distortion from the confluent effects of industry instability and expert positioning within the industry particularly positioning affecting rivalry among experts ironically experts may be most likely to mislead clients in unstable industry environments when experts command greater attention and should show greater fidelity to disinterested objectivity

divestment response to host country terrorist attacks inter firm influence and the role of temporal consistency abstract host country terrorism poses extreme uncertainty to mnes foreign operations however little is known about how mnes respond to host country terrorist attacks and how they make the related decisions drawing on the research on mnes responses to exogenous shocks and the inter firm imitation literature we argue that mnes obtain relevant information from peers actions under terrorist attacks to inform their own responses thus mnes are more likely to divest under host country terrorist attacks when peers also divest furthermore the impact of peers divestments on focal mnes divestments is magnified by the temporal consistency in peers behavioral pattern under terrorist attacks as temporal consistency reduces inferential difficulties empirical evidence based on 93 fortune us companies and their 8698 foreign subsidiaries over 2005 2015 support our hypotheses our study extends the literature on mnes responses to host country exogenous shocks and on inter firm imitation by demonstrating the social amplification of terrorism threat and the role of temporal consistency in inter firm imitation under extreme uncertainty practically we stress that mne executives should always consider their firms idiosyncratic situations when modeling peer mnes actions and be mindful that they are especially likely to imitate peers temporally consistent behaviors under extreme uncertainty

meta data envelopment analysis finding a direction towards marginal profit maximization abstract this paper discusses a new meta dea approach to solve the problem of choosing direction vectors when estimating the directional distance function the proposed model emphasizes finding the direction for productivity improvement rather than estimating the score of efficiency focusing on planning over evaluation in fact the direction towards marginal profit maximization implies a step by step improvement and wait and see decision process which is more consistent with the practical decision making process an empirical study of u s coal fired power plants operating in 2011 validates the proposed model the results show that the efficiency measure using the proposed direction is consistent with all other indices with the exception of the direction towards the profit maximized benchmark we conclude that the marginal profit maximization is a useful guide for determining direction in the directional distance function

analyzing foreign market entry strategies extending the internalization approach a new fully integrated analysis of the foreign market entry decision is presented encompassing the choice between exporting licensing joint venturing and wholly owned foreign investment the choice between acquisition and greenfield investment is examined and so too are options based on subcontracting and franchising the model extends the insights of internalization theory and draws on concepts from the economics of industrial organization a special feature of the model is the distinction between investment in production facilities and investment in distribution facilities an important practical distinction that has been overlooked in much of the international business literature the strength of competition from indigenous rivals is emphasized as a determinant of entry strategy into both production and distribution

alternative measures of environmental technology structure in dea an application abstract the nonparametric data envelopment analysis dea literature on environmental efficiency ee considers handling undesirable outputs in two alternative ways either in their original forms with the assumption that these are weakly disposable or in various translated forms with the assumption that these are strongly disposable choosing a particular approach implies adoption of a particular distinct treatment of undesirable outputs and hence yields a distinct set of ee estimates to explore the effects of the interplay between choice of ee measure and specific treatment of undesirable outputs this paper attempts to generate all possible output oriented ee measures based on these two alternative approaches furthermore guided by the argument that slacks are important in identifying properly the efficiency behavior of firms it proposes two new alternative slacks based formulations of ee one based on the range directional model and the other on the generalized proportional distance function model using a confected data set of ten firms and a real life data set of 22 oecd countries our empirical analysis reveals that first ee scores are influenced not only by the choice of disposability assumption for undesirable outputs but also by the way these are treated in various translated forms second the choice of any particular treatment of undesirable outputs plays no role in influencing the rankings of firms and third our two new alternative ee formulations are at the least viable alternatives to existing ee measures in ranking firms according to their eco efficiency behavior

power sector reform in south asia why slow and limited so far although south asian developing countries had initiated some form of electric power sector reform in the 1990s often under external lending agency pressures not much progress has been made so far and there is hardly any noteworthy example of a successful reform in the region this paper provides a brief review of power sector reform efforts in five south asian countries and uses an institutional economics framework to identify the factors shaping the success of power sector reforms four factors namely instability of rule makers poor overall acceptance slow adaptation and poor transition management are identified and their effect on the reform process of south asia are analysed the paper finds that political instability has affected the power sector reform of the region making hard decisions difficult to take slow progress of reform has also affected the sector viability as signs of adverse effects on the power sector investment and performance are already visible

technical efficiency and impact of environmental regulations in farrow to finish swine production in taiwan this article demonstrates how technical efficiency and the impact of environmental regulations of taiwanese farrow to finish swine production can be estimated in the presence of undesirable outputs the issue of measuring technical efficiencies while considering undesirable outputs has been addressed by past studies but the proper method of including undesirable outputs has always been a subject of debate this article develops a data envelopment analysis dea based model that includes undesirable outputs the technologies of desirable output production and undesirable output control are considered simultaneously this allows one to transform undesirable output into desirable output whereby a traditional shephard distance function can be used to measure technical efficiencies an approach to measuring the impacts due to environmental regulations is then derived empirical results show that larger farms are more technically efficient than small sized farms but no clear conclusions can be reached for the measures of regulatory impact among farms with different sizes on average the sample farms incurred an opportunity cost due to environmental regulations equivalent to 9 8 of market value opportunity costs rise with efficiency

nerlovian revenue inefficiency in a bank production context evidence from shinkin banks the paper further advances the contemporary methodological and empirical research on bank efficiency we introduce a bank two stage network revenue decomposition analysis based on the slack based directional inefficiency measurement framework by building upon the approaches of epure and lafuente 2015 fukuyama and weber 2009 2010 fukuyama and matousek 2017 and fare fukuyama grosskopf and zelenyuk 2015 2016 we apply the model on the segment of japanese financial institutions shinkin banks we examine the efficiency performance of shinkin banks during the period from march 2007 to march 2015 this covers the recent years after the turmoil in the us subprime residential mortgage market which started early 2007 the applied innovative framework is particularly suitable for this type of banks since the financing of their business activities is mainly dependent on the different types of deposits that the proposed model takes into consideration

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

the resource based theory of the firm interest in the resource based view of the firm continues to grow in the field of business policy and strategy recently most of this interest seems to have been focused on understanding the empirical implications of this theory and especially on how a firm s resources and capabilities can affect its performance evaluating the empirical implications of the resource based view is of course a worthwhile endeavor we present an overview of contributions in this issue

uncovering the complex relationships between political risk and mne firm legitimacy insights from libya using the before after natural experiment occasioned by the arab spring in libya we explore how market and non market activity affect foreign firm legitimacy in times of political turmoil although all mnes in libya had to cultivate strong ties to qadhafi to succeed during his 40 years of rule we found that those that also invested in social benefit projects and in social ties with families with few ties to the qadhafi family earned a broad based legitimacy that helped them survive qadhafi s overthrow our findings contribute to the political risk and political behavior literature the notion that the pursuit of firm legitimacy in general and especially in the eyes of social sector actors is an effective hedge against political risk more theoretically our findings support the addition of a social sector based path to firm legitimacy in the host country that complements and may at times substitute for the government based path to foreign firm legitimacy practically our findings suggest that mnes facing severe political risk can improve their prospects for survival by investing in relationships with influential social groups and by offering goods or services that are perceived as socially valuable

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

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

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

plant level productivity efficiency and environmental performance of the container glass industry this paper presents a methodology and empirical results based on themalmquist productivity index we measure productivity while treatingpollution as an undesirable output our estimates show that technicalchange has contributed to productivity and environmental performancegrowth in the container glass industry an energy and pollution intensivesector changes in inter plant efficiency over time have made thisproductivity growth more rapid than otherwise would have occurred withthe underlying technical change the efficiency estimates show that thereare both opportunities to improve productivity and reduce pollution in thisindustry as well as productivity losses associated with the emissionscontrol the shadow prices for nox the undesirable output we analyze is quite high compared to other regulated sectors

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

the role of environmental factors in growth accounting this paper explores a relatively new methodology the directional distance function method to analyse productivity growth the method allows us to explicitly evaluate the role that undesirable outputs of the economy such as carbon dioxide and other greenhouse gases have on the frontier production process which we specify as a piecewise linear and convex boundary function we decompose productivity growth into efficiency change catching up and technology change innovation we test the statistical significance of the estimates using recently developed bootstrap methods we also explore implications for growth of total factor productivity in the oecd and asian economies copyright 2004 john wiley sons ltd

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

modeling undesirable factors in efficiency evaluation abstract data envelopment analysis dea measures the relative efficiency of decision making units dmus with multiple performance factors which are grouped into outputs and inputs once the efficient frontier is determined inefficient dmus can improve their performance to reach the efficient frontier by either increasing their current output levels or decreasing their current input levels however both desirable good and undesirable bad factors may be present for example if inefficiency exists in production processes where final products are manufactured with a production of wastes and pollutants the outputs of wastes and pollutants are undesirable and should be reduced to improve the performance using the classification invariance property we show that the standard dea model can be used to improve the performance via increasing the desirable outputs and decreasing the undesirable outputs the method can also be applied to situations when some inputs need to be increased to improve the performance the linearity and convexity of dea are preserved through our proposal

distinguishing operational performance in power production a new measure of effectiveness by dea measuring the efficiency of power plant systems requires capturing fluctuations in the level of sales to customers as well as accounting for the effects of regulatory caps on emissions this study proposes a novel effectiveness measure considering desirable outputs and undesirable outputs via data envelopment analysis dea the new measure complements typical efficiency measures we test the validity of the proposed measure with an empirical case study of the fifty u s states and the district of columbia we find that the current interregional electricity transmission plan increases 8 56 in effectiveness for the emissions control we suggest a 9 8 reduction in electricity generation towards an effective production frontier we conclude that the proposed effectiveness measure s ability to distinguish sales and regulation effects from typical productive efficiency eliminates the bias often found in currently used measures

the economics and politics of regulation this article provides a critical survey of the literature on the economics and politics of regulation after some conceptual clarifications the article surveys the evolution of perspectives on regulation during the post second world war period emphasizing especially the interactions between intellectual changes and real world economic and political developments it then looks at some themes that are neglected in the current literature the inevitability of regulation the need to create and not simply regulate markets distributional issues dynamic considerations and the politics of regulation and suggests that incorporating these themes more closely into the discussion will improve our understanding in this area copyright 1997 by oxford university press

environmental regulation and green productivity growth empirical evidence on the porter hypothesis from oecd industrial sectors abstract green growth has become an important development strategy for oecd countries and governments have correspondingly implemented various environmental regulation policies whereas few studies have discussed the impacts of environmental regulation on green productivity growth in oecd countries based on a panel data of oecd countries industrial sectors this study analyzes the stringency of environmental regulation policies and measures green productivity growth using an extended sbm ddf approach the dynamic panel regression investigates the impacts and mechanism of environmental policy stringency on green productivity growth in oecd countries industrial sectors the main results are i porter hypothesis is validated that the environmental policy has a positive impact on green productivity growth within a certain level of stringency lower than 3 08 ii the impact turns to be adverse when the environmental regulation policy is stringent over a certain level as the compliance cost effect is higher than innovation offset effect the findings provide new empirical evidence for the strong version of the porter hypothesis and some implications for oecd countries to further promote green growth

south korean and taiwanese development and the new institutional economics the publication of books by both alice amsden and robert wade provide an opportune moment to reflect on the study of east asian development after an initial surge of interest beginning in the 1970s the field has reached a plateau and scholars recently have cast a wide net in searching for ways to extend the field in assessing the state of the art regarding the economic development of the east asian newly industrialized countries nics this review will treat three themes first i will argue that the focus on states versus markets is becoming stale and that much of the scholarly interest lies in the politics behind the economics second i argue that political scientists have underexplored the historical origins of korean and taiwanese capitalism and that such attention promises to strengthen both theories and explanations of development third i argue that the international system has been more important in promoting development in east asia than accounts in the first wave have recognized the purpose of this review is to assess the field reveal

accounting for externalities and disposability a directional economic environmental distance function abstract the existence of positive and negative externalities ought to be considered in a productivity analysis in order to obtain unbiased measures of efficiency in this research we present an additive style data envelopment analysis model that considers the production of both negative and positive externalities and permits a limited increase in input utilisation where relevant the directional economic environmental distance deed function is a unified approach based on a linear program that evaluates the relative inefficiency of the units under examination with respect to a unique reference technology we discuss the impact of disposability assumptions in depth and demonstrate how different versions of the deed model improve on models presented in the literature to date

pollution abatement activities and traditional productivity abstract this study models the joint production of good and bad output production and calculates traditional productivity when bad output production is regulated and when it is unregulated we apply this model to data for u s coal fired electric power plants for 1985 1995 and compare rates of productivity and technical change to gain an understanding of the association between pollution abatement activities and traditional rates of productivity and technical change while traditional productivity and technical change associated with abatement activities decline we conclude they are not statistically significant

total factor energy efficiency of regions in china abstract this paper analyzes energy efficiencies of 29 administrative regions in china for the period 1995 2002 with a newly introduced index most existing studies of regional productivity and efficiency neglect energy inputs we use the data envelopment analysis dea to find the target energy input of each region in china at each particular year the index of total factor energy efficiency tfee then divides the target energy input by the actual energy input in our dea model labor capital stock energy consumption and total sown area of farm crops used as a proxy of biomass energy are the four inputs and real gdp is the single output the conventional energy productivity ratio regarded as a partial factor energy efficiency index is computed for comparison in contrast to tfee our index is found fitting better to the real case according to the tfee index rankings the central area of china has the worst energy efficiency and its total adjustmentof energy consumption amount is over half of china s total regional tfee in china generally improved during the research period except for the western area a u shape relation between the area s tfee and per capita income in the areas of china is found confirming the scenario that energy efficiency eventually improves with economic growth

international corporate diversification market valuation and size adjusted evidence errunza and senbet es 7 analyze the effects of international operations on the market value of the firm both at theoretical and empirical levels the theoretical model which is largely heuristic exploits the costly supply adjustment of multinational firms mncs in providing international portfolio diversification services to investors who face differential cost barriers to direct holdings of assets across national boundaries mncs compete as financial intermediaries to undo the barriers so that in equilibrium profits are driven out mncs and pure domestic firms sell at an equivalent risk adjusted return however costly financial intermediation and the associated relative efficiency leads to a positive valuation effect for mncs relative to purely domestic firms further the equilibrium analysis implies that demand side investor barriers to international capital flows alone are inconsequential to the valuation of mncs in their pure financial role but that the interaction with the supply side costs are necessary to produce a valuation effect at the corporate level es subject the theory to an empirical analysis in a value based approach by employing a variant of tobin s 17 qratio the analysis controlling for industrial market power suggests that the relationship between the excess valuation and the degree of international involvement doi has magnified over periods characterized by severe u s government controls vis a vis the more recent periods in this paper we formalize the theoretical argument by viewing indirect portfolio diversification by mncs as a means of completing the international capital market we employ a paradigm in the unanimity literature and formally characterize the equilibrium in which there is a rationale for mnc financial intermediation we then perform an expanded empirical study by employing generalized least squares and maximum likelihood procedures since the positive relationship between excess valuation and doi as suggested in es 7 might be attributed to the so called small firm or size and the p e effects the test methodology controls for such effects also the traditional literature has relied upon foreign sales percentage as a proxy for doi in view of the well recognized limitations of this proxy we employ four different measures of international

a conditional directional distance function approach for measuring regional environmental efficiency evidence from uk regions abstract this paper by using conditional directional distance functions as introduced by simar and vanhems j econometrics 166 2012 342 354 modifies the model by fare and grosskopf eur j operat res 157 2004 242 245 and examines the link between regional environmental efficiency and economic growth the proposed model using conditional directional distance functions incorporates the effect of regional economic growth on regions environmental efficiency levels the results from uk regional data reveal a negative relationship between regions gdp per capita and environmental inefficiency up to a certain gdp per capita level after that level it appears that the relationship becomes positive as an overall result the regional environmental inefficiency gdp per capita relationship appears to have a u shape form

natural disasters and foreign direct investment the world s population has witnessed the concurrence of two powerful global trends an unprecedented growth in foreign direct investment fdi and an increase in natural disasters since investment decisions are based on an evaluation of expected risks and returns we consider whether fdi decisions are influenced by natural disasters we do so by considering the relation between fdi in 94 countries between 1984 and 2004 and the number of disasters striking those countries across a variety of empirical tests that control for two way fixed effects we find natural disasters to be negatively and statistically significantly associated with a country s fdi

non parametric frontier approach to modelling the relationships among population gdp energy consumption and co2 emissions abstract in this paper a non parametric approach based in data envelopment analysis dea is proposed as an alternative to the kaya identity a k a impact this frontier method identifies and extends existing best practices population and gdp are considered as input and output respectively both primary energy consumption and greenhouse gas ghg emissions are considered as undesirable outputs several linear programming models are formulated with different aims namely a determine efficiency levels b estimate maximum gdp compatible with given levels of population energy intensity and carbonization intensity and c estimate the minimum level of ghg emissions compatible with given levels of population gdp energy intensity or carbonization index the united states of america case is used as illustration of the proposed approach

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

congestion measurement in nonparametric analysis under the weakly disposable technology abstract congestion is a widely observed economic phenomenon where outputs are reduced due to excessive amount of inputs the previous approaches to identify congestion in nonparametric analysis only consider desirable outputs in the production process undesirable outputs are usually jointly produced with desirable outputs in this paper we propose an approach for measuring congestion in the presence of desirable and undesirable outputs simultaneously the proposed approach can discriminate between the congested dmus and the truly efficient dmus which are all efficient according to the scores calculated by the directional distance function finally an empirical example is used to illustrate the approach

estimating the shadow prices of so2 and nox for u s coal power plants a convex nonparametric least squares approach abstract weak disposability between outputs and pollutants defined as a simultaneous proportional reduction of both outputs and pollutants assumes that pollutants are byproducts of the output generation process and that a firm can freely dispose of both by scaling down production levels leaving some inputs idle based on the production axioms of monotonicity convexity and weak disposability we formulate a convex nonparametric least squares cnls quadratic optimization problem to estimate a frontier production function assuming either a deterministic disturbance term consisting only of inefficiency or a composite disturbance term composed of both inefficiency and noise the suggested methodology extends the stochastic semi nonparametric envelopment of data stoned described in kuosmanen and kortelainen 2011 applying the method to estimate the shadow prices of so 2 and no x generated by u s coal power plants we conclude that the weak disposability stoned method provides more consistent estimates of market prices

regulation institutions and commitment in telecommunications a comparative analysis of five country studies within any system of utility regulation there is a tension between the ability to commit to a stable set of rules and the ability to respond flexibly to changing circumstances countries differ in their institutional endowments and hence in the ways in which they can resolve this tension a first group of countries can design regulatory systems that afford the regulator substantial formal discretion to respond to changing circumstances and can use process to restrain arbitrary action a second group of countries can restrain arbitrary action only by calling on specific substantive rules and may have to sacrifice some flexibility to achieve credible commitment a third group may lack the domestic institutions to put in place a credible and workable regulatory system of any kind

the assessment international competitiveness the concept of international competitiveness as applied to national economies is a popular one politicians businessmen and economists alike re fer to it in day to day discussion when looking at the external export import market share or trade balance performance of different countries indi cators are produced showing changes in or levels of various countries competitiveness e g the relative price or cost indices regularly published by the imf and the oecd or the absolute measures produced by organizations such as the geneva world economic forum and the lausanne institute for management development governments of ten instigate research on the matter as for instance in the case of the 1993 us competitiveness policy council orthe 1995 eu competitiveness advisory group yet it has recently been argued by paul krugman that competitiveness is a meaningless word when applied to national economies and the obsession with competitiveness is both wrong and dangerous krugman 1994 p 44 apositionkrugman forcefully reaffirms in his contribution to this issue of the oxford review of economic policy

news droughts news floods and u s disaster relief this paper studies the influence of mass media on u s government response to approximately 5 000 natural disasters occurring between 1968 and 2002 these disasters took nearly 63 000 lives and affected 125 million people per year we show that u s relief depends on whether the disaster occurs at the same time as other newsworthy events such as the olympic games which are obviously unrelated to need we argue that the only plausible explanation of this is that relief decisions are driven by news coverage of disasters and that the other newsworthy material crowds out this news coverage

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

a critique of non parametric efficiency analysis in energy economics studies abstract the paper reexamines non additive environmental efficiency models with weakly disposable undesirable outputs appeared in the literature of energy economics these efficiency models are used in numerous studies published in this journal and other energy related outlets recent studies however have found key limitations of the weak disposability assumption in its application to environmental efficiency analysis it is found that efficiency scores obtained from non additive efficiency models can be non monotonic in pollution quantities under the weak disposability assumption which is against common intuition and the principle of environmental economics in this paper i present taxonomy of efficiency models found in the energy economics literature and illustrate the above limitations and discuss implications of monotonicity from a practical viewpoint finally i review the formulations for a variable returns to scale technology with weakly disposable undesirable outputs which has been misused in a number of papers in the energy economics literature an application to evaluating the energy efficiencies of 23 european union states is presented to illustrate the problem

multi output efficiency with good and bad outputs abstract cherchye de rock dierynck roodhooft and sabbe 2013 introduced a dea methodology that is specially tailored for multi output efficiency measurement the methodology accounts for jointly used inputs and incorporates information on how inputs are allocated to outputs in this paper we present extensions that render the methodology useful to deal with undesirable or bad outputs in addition to desirable or good outputs interestingly these extensions deal in a natural way with several limitations of existing dea approaches to treat undesirable outputs we also demonstrate the practical usefulness of our methodological extensions through an application to us electric utilities

the institutional environment for infrastructure investment the empirical evidence that links political institutions to economic outcomes has grown dramatically in recent years however virtually all of this analysis is undertaken using data from the past three decades this paper extends this empirical framework by performing a two century long historical analysis of the determinants of infrastructure investment in a panel of over 100 countries the results demonstrate that political environments that limit the feasibility of policy change are an important determinant of investment in infrastructure copyright 2002 oxford university press

regulation of privatized utilities the chilean experience abstract the privatization of chile s public utilities has led to substantial new investment and improvements in internal efficiency however the limited information available to regulators combined with their insufficient technical capacity have combined to prevent efficiency increases being fully passed on to consumers in price reductions in fact drastic price cuts have occurred only where competition has emerged so achieving competition wherever possible should be the main policy goal competition can be enhanced by either modifying existing regulations as happened in long distance telecommunications or by a more active antitrust policy to achieve this the regulatory institutions clearly need strengthening

banks efficiency and credit risk analysis using by production approach the case of iranian banks abstractthis article uses a by production approach that integrates credit risk to monitor bank efficiency the method overcomes the possible misspecification issues of the commonly assumed weak disposability wda of undesirable outputs in addition our measure extends the classic by production approach by including statistical aspects through subsampling techniques we have also provided an algorithm to correct related infeasibilities using this approach we investigate the performance of iranian banks and credit risk management in the sector for the period 1998 2012 non performing loans npls have been used as an undesirable output and proxy for credit risk in our models based on our empirical results although the banks generally exhibited efficiency improvements over time their credit risk performance deteriorated considerably after the regulatory changes introduced in 2005 these findings confirm that credit quality can be monitored more actively across iranian banks

dodging bullets the heterogeneous effect of political violence on greenfield fdi the relationship between political violence and greenfield foreign direct investment is contingent on the type of violence characteristics of the investment receiving sector and extent to which the investing firm is geographically diversified this paper presents an analysis with a dynamic fixed effects model for a panel of 90 developing countries from 2003 to 2012 the analysis shows that nationwide political conflict is negatively associated with total and non resource related greenfield foreign direct investment but not with resource related greenfield foreign direct investment the insensitivity to political conflict of multinational firms in the resource sector is associated with the high profitability of natural resource extraction and the companies geographic constraints on location choice during the period of estimation in the non resource sector the less geographically diversified firms are most sensitive to the risk of conflict

green productivity growth in china s industrial economy abstract this paper uses a directional distance function ddf and the malmquist luenberger productivity index to estimate the changing patterns of green total factor productivity gtfp growth of 38 chinese industrial sectors during the period 1980 2010 unlike the measures of traditional total factor productivity tfp growth the ddf incorporates carbon dioxide emissions as an undesirable output directly into the production technology which credit sectors for simultaneously reducing their emissions and increasing their output our estimates of aggregate and sector level gtfp growth reveal that chinese industry is not yet on the path towards sustainable low carbon growth a dynamic panel data analysis of the determinants of gtfp across sectors is used to identify factors that might rectify this situation including state owned enterprise soe reform the growth of small private enterprises continued openness to foreign investment and higher spending on r d particularly in emission intensive sectors

productivity growth and environmental regulations accounting for undesirable outputs analysis of china s thirty provincial regions using the malmquist luenberger index this paper employs the malmquist luenberger ml productivity index to evaluate china s growth in total factor productivity tfp incorporating undesirable outputs during the period from 1989 to 2008 the ml productivity index and its components technical and efficiency changes are derived from the directional distance function which gives credit for an increase in good outputs and for reductions in undesirable outputs the average annual ml productivity growth accounting for undesirable outputs is 2 46 whereas the value of the traditional malmquist productivity index is 4 84 showing that the true tfp growth in china is overestimated if undesirable outputs are ignored we explore the strictness in enforcing environmental regulations and its impact on improvements in ml productivity the results show that the enforcement of environmental regulations in china is in general far below the levels achieved in the best performing regions and that the more stringent enforcement of environmental regulations would help to improve ml productivity growth in china

patterns in the expansion of u s banks foreign operations combining foreign direct investment theory with data on 32 countries from the federal reserve board we examined u s banks patterns of foreign operations including their levels of banking services and choice of organizational forms in host countries results generally supported predictions but only in developed countries the lack of support in rapidly growing markets of asia and latin america raises serious theoretical concerns and presents fresh research opportunities into the global banking industry

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

measuring technical efficiency in the presence of pesticide spillovers and production uncertainty the case of dutch arable farms pesticides dynamic effects and production uncertainty play an important role in farmers production decisions pesticides have a current production impact through reducing crop damage in the current period and a future impact through impacting the farm biodiversity which alters the future production environment this study presents the difference in inefficiency arising from models that ignore the dynamic effects of pesticides in production decisions and the impact of production uncertainty a dynamic data envelopment analysis dea model is applied to outputs inputs and undesirables of dutch arable farms over the period 2003 2007 a bootstrap approach is used to explain farmers performance providing empirical representations of the impact of stochastic elements on production these empirical representations are used to adjust firms inefficiency scores to incorporate production uncertainty in efficiency evaluation we find that efficiency increased dramatically when a production technology representation that considers both pesticides dynamic impacts and production uncertainty is adopted

pesticide use environmental spillovers and efficiency a dea risk adjusted efficiency approach applied to dutch arable farming pesticides are widely used by crop producers in developed countries to combat risk associated with pests and diseases however their indiscriminate use can lead to various environmental spillovers that may alter the agricultural production environment thus contributing to production risk this study utilises a data envelopment analysis dea approach to measure performance of arable farms incorporating pesticides environmental spillovers and output variance as undesirable outputs in the efficiency analysis and taking explicitly into account the effect of pesticides and other inputs on production risk the application focuses on panel data from dutch arable farms over the period 2003 2007 a moment approach is used to compute output variance providing empirical representations of the risk increasing or decreasing nature of the used inputs finally shadow values of risk adjusted inputs are computed we find that pesticides are overused in dutch arable farming and there is a considerable evidence of the need for decreasing pesticides environmental spillovers

a multiplicative environmental dea approach to measure efficiency changes in the world s major polluters we propose a multiplicative environmental data envelopment analysis me dea approach to measure the performance of 46 countries that generate most of the world s carbon dioxide co2 emissions in the model we combine economic labour and capital environmental freshwater and energy inputs with a desirable output gdp and three undesirable outputs co2 methane and nitrous oxide emissions we rank each country according to the optimum use of its resources employing a multiplicative extension of environmental dea models by computing partial efficiency scores for each input and output separately we thus identify major sources of inefficiency for all sample countries based on the partial efficiency scores obtained from the model we define aggregate economic energy and environmental efficiency indexes for 2002 2007 and 2011 reflecting points in time before and after the official enactment of the kyoto protocol we find that for most countries efficiency scores increase over this period in addition there exists a positive relationship between economic and environmental efficiency although at the same time our results suggest that environmental efficiency cannot be realized without first reaching a certain threshold of economic efficiency we also find support for the paradox of plenty whereby an abundance of natural and energy resources results in their inefficient use

the dynamic efficiency of regulatory constitutions in this article we model regulation as a repeated game between a utility facing a random sequence of demands and a regulator tempted to underreward past investment rate of return regulation designed with a constitutional commitment to an adequate rate of return on capital prudently invested is able to support an efficient investment program as a subgame perfect nash equilibrium for a larger set of parameter values than rate of return regulation without such a commitment furthermore rate of return regulation is superior to price regulation according to the same criterion assuming that the regulator is unable to make state contingent transfer payments

measuring environmentally sensitive productivity growth an application to the urban water sector the energy use and greenhouse gas emissions in the provision of urban water and sewerage services have become an increasingly important issue in recent times however the impact of negative externalities such as greenhouse gas emissions on the productivity of urban water provision has received less attention in the literature this paper applies the global malmquist luenberger gml productivity index which accounts for undesirable outputs in order to evaluate the productivity trends in the australian urban water sector results indicate that the inclusion of greenhouse gas emissions significantly influences the productivity measurement findings also indicate that the conventional index which disregards undesirable outputs over states the productivity growth despite a declining trend in greenhouse emissions over the period the overall productivity trend of the urban water sector experienced a downward trend while accounting for bad output this productivity decline occurs in a period of prolonged drought water security concerns and increased reliance on desalinization and water recycling

distinguishing between related and unrelated international geographic diversification a comprehensive measure of global diversification this paper argues that it is important to distinguish between related and unrelated international geographic diversification when measuring impact of diversification on performance it then extends the jacquemin berry entropy measure to propose a comprehensive measure of global diversification that comprises related and unrelated product diversification and related and unrelated international geographi diversification it suggests a classification of firms based on diversification strategies and proposes hypotheses for future research

slacks based efficiency measures for modeling environmental performance we develop two slacks based efficiency measures for modeling environmental performance on the basis of environmental dea technology of the two measures one is a composite index with a higher discriminating power for modeling economic environmental performance and the other can be used to estimate the impacts of environmental regulations we apply the proposed measures to model the co2 emissions of 30 oecd countries from 1998 to 2002 and present the results obtained

economic value of greenhouse gases and nitrogen surpluses society vs farmers valuation abstract livestock supply must challenge the growth of final demand in the developing countries this challenge has to take into account its ecological effects since the dairy and livestock sectors are clearly pointed out as human activities which contribute significantly to environmental deterioration therefore livestock activity models have to include desirable and undesirable outputs simultaneously using this perspective we implement a data envelopment analysis model to evaluate shadow prices of outputs under contradictory objectives between the society and the farmers we show that farmers are able to reduce pollution significantly if society accepts to balance farmers opportunity cost finally we observe that initial levels of the co 2 tax implemented in european countries are in line with farmers valuation while the current level of the co 2 tax tends to reach the value of pollution targeted by the society

a review of research on the growth of multinational enterprises a penrosean lens abstract we provide a comprehensive review of the growth of multinational enterprises mnes based on a quarter century 25 years of scholarly international business publications we synthesize research insights on the determinants of the growth of mnes through the lens of penrose s theory of firm growth which is the most influential theoretical perspective on firm growth the review takes stock of the research findings on the facilitators constraints and the trajectory of growth of mnes and elaborates on the commonalities and differences between research on the growth of mnes that draws on penrose s theory and research that does not this comparison highlights the opportunity to build an internally coherent theory of the growth of mnes that is a theory that connects what an mne is to what determines an mne s growth it also indicates that past research placed a strong emphasis on exogenous factors e g cross country distances as key constraints on growth even though the penrosean lens suggests a close consideration of endogenous factors that drive international growth as well as endogenizing the ostensibly exogenous growth determinants the review highlights the importance of firm specific managerial knowledge and learning which shapes the direction of the growth of mnes and ensures its administrative coherence
