the empirical analysis of the determinants for environmental technological change a research agenda abstract technological change is usually considered a necessary albeit not sufficient condition for a transition to sustainability however the empirical analysis of the determinants to environmental technological change has not received too much attention in the environmental ecological economics literature and many open questions remain in this context based on a careful review of the literature this paper argues that further analysis should address several issues at different levels i e regarding the conceptual framework the thematic scope of the studies some methodological issues and other aspects related to the environmental policy variable first an integrated conceptual framework which takes into account the interplay between relevant variables influencing environmental technological change i e factors internal and external to the firm and characteristics of the environmental technologies and all the stages of this process with a greater emphasis on the invention stage should be developed other aspects should then be tackled including a focus on several themes i e a greater attention to cross sectoral technologies the barriers to different types of environmental technologies the international dimension of environmental technological change and environmental technological change in small and medium size enterprises methodological issues combination of case studies and econometric modelling and several issues related to the environmental policy variable

environmental regulation industrial innovation and green development of chinese manufacturing based on an extended cdm model abstract as for the academics and policymakers more attention has been given to the issue on how to drive green development of the manufacturing through regulations and innovations we construct the extended crepon duguet mairesse cdm model and employ the panel data of chinese manufacturing industries during 2003 2014 to examine the effects of environmental regulation on industrial innovation and green development the findings reveal that 1 in the long term environmental regulation has crowded out r d investment 2 environmental regulation has inhibited patent outputs so that the weak version of porter hypothesis is not underpinned 3 in the short term environmental regulation has promoted the improvements of labor productivity energy efficiency and environmental efficiency in the manufacturing industry excluding green total factor productivity gtfp whereas in the long term environmental regulation only has increased energy efficiency while it has obstructed labor productivity which provides no support for the strong version of porter hypothesis 4 different innovation outputs have distinct influences on labor productivity energy efficiency environmental efficiency and gtfp finally this paper provides pertinent policy implications

technical change external economies and the porter hypothesis abstract michael porter introduces the idea that environmental regulations may benefit affected firms this paper derives results consistent with porter s hypothesis by employing a general equilibrium framework with a large number of agents external economies of scale in production and discrete changes in technology the model shows that endogenous technical change makes porter s hypothesis feasible however a policy that produces results consistent with porter s hypothesis is not necessarily optimal

thermal plant bids and market clearing in an electricity pool minimization of costs vs minimization of consumer payments the spanish wholesale electricity market started on january 1st 1998 though it is based on simple price quantity bids it incorporates some provisions to take thermal plant running requirements into account this paper presents these rules and its mathematical treatment focusing on a possible implementation of the minimum income condition which allows thermal generators to declare minimum stable loads it also shows another key point in the debate whether the algorithm should minimize costs or consumer payments

optimal retailer investments in green operations and preservation technology for deteriorating items abstract this paper examines the impact of dynamic retailer investments in green operations while considering the reference price effect a replenishment problem based on joint pricing dynamic investment in green operations preservation technology and optimal replenishment times for deteriorating items is considered as a way to maximize retailer profit in this problem the demand rate depends on the sales and reference prices as well as green concern level optimal control theory is employed to obtain a dynamic investment rate and a simulated annealing algorithm is used to find the solution of the nonlinear constraint optimization problem which determines the price preservation technology investment and replenishment cycle time in addition computational simulations and sensitivity analyses are carried out to offer managerial insights the findings suggest that continuous investment in green operations and preservation technology can significantly improve the retailer s financial performance the consumer reference price is an important influence on the retailer s decision to invest in green operations furthermore results show that the higher price sensitivity of the market always discourages the retailer from investing in green operations the retailer needs to invest more in green operations for products with relatively high unit value

plant vintage technology and environmental regulation abstract we use data on productivity and pollution abatement costs at individual pulp and paper mills to test whether the impact of environmental regulation on productivity differs by plant vintage and technology plants with higher pollution abatement costs have significantly lower productivity levels this relationship differs greatly based on a plant s technology with productivity at integrated mills being greatly affected by abatement costs while the impact at non integrated mills is negligible plant vintage does not seem to matter with older and newer plants showing similar impacts reported abatement costs appear to substantially understate the true costs of abatement accounting for the impact of technology differences makes some difference in the estimated overall impact of environmental regulation

substitution effects in cvm values there is increasing recognition that statistical estimates of the average willingness to pay for environmental programs may be biased by the failure of respondents or of the statistical methodology to consider the effect of substitute programs and goods we design and implement a cvm survey that estimates the impact of substitution effects on the willingness to pay for an environmental program we find a statistically significant impact and suggest that the set of potential substitutes is very large

regulatory attitudes and environmental innovation in a model combining internal and external r d the extent to which environmental regulatory institutions are either green or brown impacts not just the intensity of regulation at any moment but also the incentives for the development of new pollution control technologies we set up a strategic model of r d in which a polluter can deploy technologies developed in house or license technologies developed by specialist outsiders an eco industry polluters exert r d effort and may even develop redundant technologies to improve the terms on which they procure technology from outside we find that while regulatory bias has an ambiguous impact on the best available technology strategic delegation to systematically biased regulators can improve social welfare

the effect of clean water regulation on profitability testing the porter hypothesis previous theoretical research provides opposing arguments regarding the effect of environmental regulation on profitability this study provides empirical evidence on this debated effect by testing the strong version of the porter hypothesis we employ panel data analysis to examine the effect of water regulation as measured by permitted wastewater discharge limits on the profitability of publicly held firms operating within the chemical manufacturing industries we find that tighter water regulation meaningfully lowers profitability by reinterpreting profitability in terms of sales and costs the results demonstrate that tighter water regulation increases costs conditioned on a given level of sales

environmental regulation and competitiveness empirical evidence on the porter hypothesis from european manufacturing sectors abstract this paper investigates the weak and strong versions of porter hypothesis ph focusing on the manufacturing sectors of 17 european countries between 1997 and 2009 the hypothesis that well crafted and well enforced regulation would benefit both the environment and the firm was originally proposed by porter 1991 and porter and van der linde 1995 to date the literature has analyzed the impact of environmental regulation on innovation and on productivity mostly in separate analyses and focusing on the usa the few existing contributions on europe study the effect of environmental regulation either on green innovation or on performance indicators such as exports we instead look at overall innovation and productivity impacts first focusing on overall innovative activity allows us to account for potential opportunity costs of induced innovations second productivity impacts are arguably the most relevant indicators for the strong ph as a proxy of environmental policy stringency we use pollution abatement and control expenditures pace one of the few sectoral level indicators available we remedy upon its main drawback namely potential endogeneity by adopting an instrumental variable estimation approach we find evidence of a positive impact of environmental regulation on the output of innovation activity as proxied by patents thus providing support in favor of the weak ph this result is in line with most of the literature on the other front we find no evidence in favor of the strong ph as productivity appears to be unaffected by the degree of pollution control and abatement efforts

environmental policy with endogenous plant locations in a game between the governments of two countries each chooses its own environmental policy the nash equilibria of the game are generally not pareto optimal on the one hand each country may want to attract industry giving it an incentive to choose low environmental taxes or standards on the other hand if disutility from pollution is sufficiently high each country might prefer that a firm locates only in other countries this effect tends to make the environmental policy under non cooperation stricter than it would be with cooperation

the optimal research and development portfolio of low carbon energy technologies a study of china to support decision making for an optimal portfolio strategy for low carbon energy technology research and development r d this study proposes a dynamic two stage stochastic programming model taking into account both the uncertainty of technological change and damages of climate change based on china s economic and technology level and expert elicitation an r d investment portfolio strategy looking at three low carbon technologies carbon capture and storage ccs solar photovoltaic pv and nuclear including nine projects is investigated through the proposed model the optimized results show that the optimal r d technology portfolio is robust to different levels of risk in climate damage however the total social costs for the optimal r d technology portfolio is lowest in the medium risk of climate damage scenario under different opportunity costs the composition of the optimal r d portfolio varies however projects for each of the three technologies always constitute the optimal r d portfolio furthermore the implication is that a technology synergistic r d strategy is conducive to enhancing the level of co2 abatement and reducing the total social cost

estimation of distance decay functions to account for substitution and spatial heterogeneity in stated preference research in a site selection choice experiment various hypotheses are tested related to spatial heterogeneity in willingness to pay wtp for environmental improvements spatial heterogeneity is measured through distance decay effects substitute sites inside and outside the experiment s choice set and spatial trend variables we demonstrate that distance decay functions differ between users and nonusers and across study sites also the distance to substitutes outside the choice set explains spatial variation in wtp we show that further extending the model with spatial trend variables reveals additional spatial heterogeneity in choices accounting for spatial heterogeneity patterns results in significantly different wtp estimates for environmental improvements jel q25 q51

double sided auction mechanism design in electricity based on maximizing social welfare an efficient electricity double sided auction mechanism should control market power and enhance the social welfare of the electricity market based on this goal the paper designs a new double sided auction mechanism in the new mechanism the social welfare contribution of each participant plays a pivotal role because this contribution is the critical factor in market clearing payment settling and transaction matching rules in particular each winner of the auction can gain transfer payments according to his contribution to social welfare in the electricity market and this gives the mechanism the ability to control the market power of some participants at the same time this mechanism ensures that the market organizer balances his budget we then conduct a theoretical and empirical analysis based on the spanish electricity market both of the results show that compared to the uniform pricing mechanism the new mechanism can reduce market power of participants and enhance the social welfare of the electricity market

environmental regulations and productivity growth the case of fossil fueled electric power generation this paper measures and analyzes the effect of sulfur dioxide emission restrictions on the rate of productivity growth in the electric power industry over the 1973 79 business cycle a firm specific measure of regulatory intensity is developed which depends on the severity of the emission standard the extent of enforcement and the unconstrained emission rate relevant to each utility the results indicate that emission regulations result in significantly higher generating costs primarily from the increased use of low sulfur fuels the average rate of productivity growth was reduced by 0 59 percentage points per year for constrained utilities

environmental innovation and environmental performance abstract by estimating a simultaneous panel data model of environmental innovation and toxic air pollution this paper identifies bi directional causal links between the two we study a panel of 127 manufacturing industries over the period 1989 2004 pollutant emissions are an implicit measure of policy stringency and environmental patent counts are used to measure environmental innovation after accounting for the joint endogeneity we find that environmental innovation is an important driver of reductions in us toxic emissions conversely we find that tightened pollution targets induce environmental innovation however our estimates indicate that the environmental policy multiplier the proportionate contribution of induced innovation to long run emission reduction is small

beyond the question does it pay to be green how much green and when abstract this research investigates the relationship between green management and performance in italian firms the analysis compares innovation and productivity of firms with similar features but different environmental activities firms are matched on a rich set of covariates extending the coarsened exact matching to survey data matched data are analysed with parametric and non parametric tests and endogenous treatment regression the analysis shows that the relationship between green management and performance is u shaped green firms are performing no better than firms with no environmental activity especially in energy intensive sectors among green firms more advanced environmental management is associated with higher performance overall the results suggest that green management has strong sectoral patterns and no linear relationship with performance findings suggest that green managers should pursue a comprehensive environmental management system sectoral specific policies to promote environmentally friendly activities are needed when green activities are not paying off

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

bargaining to preserve a unique ecosystem the role of anticipatory investments to establish stronger bargaining positions abstract a forester and a conservation organization bargain over the commercial exploitation or preservation of a forested tract of land with unique ecological characteristics the forester can improve its bargaining position by preparing a portion of the land for future timber production prior to negotiations between the two however doing so decreases the preservation value of the forest as well as the compensation the conservation group is willing to pay to preserve the forest the analysis suggests that the forester will begin preparing the land for timber production prior to negotiations only when the value of the land in timber production is significantly lower than the preservation values of the conservation group

complements substitutes budget constraints and valuation this study employs a multi program contingent valuation cvm design tosimultaneously assess the value of three ecosystem conservation programsin alberta canada the design is different from most other cvm designsand has several different features including the natural incorporation ofdirect reminders of substitute complementary programs and budgetconstraints in contrast to the findings of other studies two of the environmentalprograms appear to be complements and other combinations of the programssuggest an absence of substitution effects the multi program model ismore informative and robust in terms of theoretical validity and expectedrelationships with demographic and recreational characteristics of therespondents

how environmental regulations affect innovation in the australian oil and gas industry going beyond the porter hypothesis the impact of environmental regulation on innovation is of central interest to many industries and policy makers alike while traditional research adopts a top down view of regulation and attempts to measure the innovation response the more bottom up view of contemporary theory argues that firms produce innovations that exceed compliance levels as a competitive strategy we approach this dichotomy by investigating innovation introduced by australian oil and gas firms in light of environmental regulatory compliance burden and firm level characteristics including competitive capabilities analyses of survey responses executive level interviews and conference proceedings reveal both regulatory top down and competitive advantage bottom up perspectives explain innovation in this industry regression analyses reveal that product service and novel innovations all types are related to a high compliance burden competitive skills research and development activity and engagement in formal collaborations interview and conference data add nuance to our findings revealing collaborative compliance frameworks result in similar innovation outcomes

optimal pricing strategies for a cluster of goods own and cross price effects with correlated tastes contingent valuation methods are used to identify observed and unobserved preferences of goods and services we apply these methods in the context of multivariate probit analysis to compute willi

environmental policy and competitiveness the porter hypothesis and the composition of capital abstract the porter hypothesis suggests a win win situation in the sense that environmental policy improves both environment and competitiveness the suggestion received strong criticism from economists driven by the idea that if opportunities exist firms do not have to be triggered by an extra cost in this paper a model is developed which confirms this point but which also draws attention to some general mechanisms that relax the trade off considerably downsizing and modernization of firms subject to environmental policy will increase average productivity and will have positive effects on the marginal decrease of profits and environmental damage

the dynamic capabilities of firms an introduction an expanded paradigm is needed to explain how competitive advantage is gained and held firms resorting to resource bas ed strategy attempt to accumulate valuable technology assets and employ an aggressive intellectual property stance however winners in the global marketplace have been firms demonstrating timely responsiveness and rapid and flexible product innovation along with the management capability to effectively coordinate and redeploy internal and external competences this source of competitive advantage dynamic capabilities emphasizes two aspects first it refers to the shifting character of the environment second it emphasizes the key role of strategic management in appropriately adapting integrating and re configuring internal and external organizational skills resources and functional competences toward changing environment 3 only recently have researchers begun to focus on the specifics of developing firm specific capabilities and the manner in which competences are renewed to respond to shifts in the business environment the dynamic capabilities approach provides a coherent framework to integrate existing conceptual and empirical knowledge and facilitate prescription this paper argues that the competitive advanis tage of firms stems from dynamic capabilities rooted in high performance routines z operating inside the firm embedded in the firm s processes and conditioned by its history it offers dynamic capabilities as an emerging paradigm of the modern business j firm that draws on multiple disciplines and advances with the help of industry studies in the usa and elsewhere

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

sustainable production and consumption systems cooperation for change assessing and simulating the willingness of the firm to adopt develop cleaner technologies the case of the in bond industry in northern mexico abstract over the last decade literature on the greening of industry and environmental policy has provided numerous important insights into the determinants of the firm s innovative behaviour in cleaner technologies however this literature still lacks empirically tested theoretical models this paper contributes to fill this gap proposing a definitional system that enables the testing of hypotheses of dependence between willingness to innovate in cleaner technologies and its determinants and to explore the conditions under which the firms innovative behaviour could be fostered regression and simulation outcomes indicate against the general wisdom that stringent environmental regulation without consideration to the dynamics of technical change and environmental and economic risk perceptions in the part of firms would play against the promotion of innovation in cleaner production

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

lead markets and regulation a framework for analyzing the international diffusion of environmental innovations abstract environmental regulations are often intended to stimulate the generation and adoption of eco efficient innovations an important argument in the public debate is also the creation of new markets for environmentally benign products processes and services in other countries and the generation as a result of export opportunities for the pioneering country lead markets research on lead markets has not however focused on environmental innovations to date we therefore extend the lead market model to environmental innovations and take particular account of the peculiarities of such innovations in particular the public good character of environmental benefits and the role of regulations this approach is applied to two case studies wind energy and fuel efficient passenger cars in both cases the innovation was initially adopted in one country other countries subsequently adopted the same innovation design favored by the lead market which in turn developed into a large exporter in the wind generation and car industries respectively we discuss the regulations employed and the reasons for the international success of the innovations induced by them our findings demonstrate that when supported by global demand or regulatory trends strict regulation results in the creation of lead markets finally we provide recommendations on how our model could be used for further research and in the development of a coordinated environmental and innovation policy

a resource based perspective on corporate environmental performance and profitability drawing on the resource based view of the firm we posited that environmental performance and economic performance are positively linked and that industry growth moderates the relationship with the returns to environmental performance higher in high growth industries we tested these hypotheses with an analysis of 243 finns over two years using independently developed environmental ratings results indicate that it pays to be green and that this relationship strengthens with industry growth we conclude by highlighting the study s academic and managerial implications making special reference to the social issues in management literature

it pays to be green a premature conclusion it has been claimed that good environmental performance can improve firms economic performance however because of e g data limitations the methods applied in most previous quantitative empirical studies on effects of environmental performance on economic performance of firms suffer from several shortcomings we discuss these shortcomings and conclude that previously applied methods are unsatisfactory as support for a conclusion that it pays for firms to be green then we illustrate the consequences of these shortcomings by performing several regression analyses of the effect of environmental performance on economic performance using a panel data set of norwegian plants a pooled regression where observable firm characteristics like e g size or industry are controlled for confirms a positive effect of environmental performance on economic performance however the estimated positive effect could be due to omitted unobserved variables like management or technology when the regression model controls for unobserved plant heterogeneity the effect is generally no longer statistically significant hence although greener plants tend to perform economically better the analysis provides little support for the claim that it is because they are greener these empirical findings further indicate that a conclusion that it pays to be green is premature

environmental policy stringency and technological innovation evidence from survey data and patent counts this article uses patent data to examine the impact of public environmental policy on innovations in environment related technology the analysis is conducted using data on an unbalanced panel of 77 countries between 2001 and 2007 drawing upon data obtained from the european patent office epo world patent statistical patstat database and the world economic forum s wef executive opinion survey the results support our hypotheses concerning the positive role of both general innovative capacity and environmental policy stringency on environment related innovation a subsequent two stage model assesses the factors which drive innovation in general and uses the fitted values to estimate environmental innovation while the analysis is conducted on a smaller sample they confirm the findings of the reduced form model

dynamic incentives of environmental regulations the effects of alternative policy instruments on technology diffusion abstract we develop a framework for comparing empirically the effects of alternative environmental policy instruments on the diffusion of new technology market based and command and control approaches can he quantitatively compared by estimating the economic penalty that firms through their actions reveal to be associated with violation of standards in the context of concerns about global climate change we empirically examine the likely effects of pigouvian taxes technology adoption subsidies and technology standards we employ state level data on the diffusion of thermal insulation in new home construction comparing the effects of energy prices insulation cost and building codes

the dynamics of technological substitution the case of eco innovation diffusion of surface cleaning products some eco innovations have already reached a mature state but they diffuse slowly there is little known about the importance of various factors on the diffusion process of eco innovations the aim of this research is to propose a conceptual model for eco innovation diffusion where particular case study of eco innovation micro fibre cloth mfc for surface cleaning purposes is given the work will study the relative importance of various motivations on diffusion processes as well as the influence of information campaigns this novel methodology has been developed under the system dynamics framework and is coupled with the logistic regression model structural validation tests were done for the proposed model the methodology is proposed then the integrated empirical study and system dynamics model are completed the results of the logistic regression models show that the overall attitudes and social influence has the most dominant impact on intention to use the studied eco innovation products the most sensitive parameters in the system dynamics model were found to be the adoption faction of information received by word of mouth households adopting micro fibre cloth at the beginning of the simulation and the contact rate per household the proposed methodology and developed mathematical model can also be used as the basis for other studies of other diffusion processes since system dynamics modelling is a white box modelling approach and the structure of the model can be enhanced with the latest results from other studies

green r d for eco innovation and its impact on carbon emissions and firm performance abstract over the past four decades the results of the debates about the relationship between corporate environmental performance and corporate financial performance have remained inconclusive due to the lack of theoretical underpinning and availability of data this paper examines the impact of green research and development investment for eco innovation on environmental and financial performance the research is based on the resource based view and the natural resource based view which explicitly recognize the importance of resources and capabilities using a sample of japanese manufacturing firms during the period of 2001 2010 the study focuses on green research and development investment as a key proxy of eco innovation and carbon emissions in environmental performance our results show the presence of a negative relationship between green research and development and carbon emissions while green research and development is positively related to financial performance at the firm level our findings explicitly support that in order for firms to adopt a proactive environmental strategy to manage their environmental and financial performance to the best advantage they urgently need to organise unique resources and capabilities the findings of this study provide valuable insights and basis of scientific debate on how firms to engage unique organizational resources and capabilities for superior corporate environmental and financial performance

productivity growth and environmental regulation in mexican and u s food manufacturing many argued during the nafta debate that trade liberalization would favor mexican over u s food processors especially because of lax environmental laws south of the border we find through an examination of profit functions that productivity growth in mexico has outstripped that in the united states suggesting free trade indeed will benefit mexican suppliers u s pollution regulations have had no impact on the profitability or productivity of u s food manufacturing in contrast mexico s swiftly rising environmental standards have enhanced food processors productivity growth corroborating the porter hypothesis pollution law therefore has favored mexican over u s food processing but for reasons few had anticipated

generation flexibility in ramp rates strategic behavior and lessons for electricity market design abstract a ramp rate usually defines the speed at which an electric power producer can decrease or increase its production in limited time the availability of fast ramping generators significantly affects the economic dispatch especially in the systems with high penetration of intermittent energy sources e g wind power since the fluctuations in supply are common and sometimes unpredictable one of the regulatory practices of how to impel generators to provide their true ramp rates is to separate the stages of submitting the bids on ramp rate and production in this paper we distinguish two types of market structures one stage when electric power producers are deciding their production and ramp rate at the same time or two stage when generators decide their ramp rate first and choose their production levels at the second stage we employ one stage and two stage equilibrium models respectively to represent these market setups and use a conjectured price response parameter ranging from perfect competition to the cournot oligopoly to investigate the effect of the market competition structure on the strategic decisions of the generators we compare these two market setups in a symmetric duopoly case with two time periods and prove that in the two stage market setup the level of ramp rate is independent of the strategic behavior in the spot market and generally lower than the one offered in the one stage setup we also show that the ramp rate levels in one and two stage models coincide at the cournot oligopoly we extend the model to asymmetry several load periods portfolio bidding and uncertainty and show that withholding the ramp rate still occurs in both models our findings prove that market regulators cannot rely on only separating the decision stages as an effective measure to mitigate market power and in certain cases it may lead to an adverse effect

do corporate global environmental standards create or destroy market value arguments can be made on both sides of the question of whether a stringent global corporate environmental standard represents a competitive asset or liability for multinational enterprises mnes investing in emerging and developing markets analyzing the global environmental standards of a sample of u s based mnes in relation to their stock market performance we find that firms adopting a single stringent global environmental standard have much higher market values as measured by tobin sq than firms defaulting to less stringent or poorly enforced host country standards thus developing countries that use lax environmental regulations to attract foreign direct investment may end up attracting poorer quality and perhaps less competitive firms our results also suggest that externalities are incorporated to a significant extent in firm valuation we discuss plausible reasons for this observation

does energy policy hurt international competitiveness of firms a comparative study for germany switzerland and austria this paper investigates the impact of energy policies on the export performance of firms there has been a long policy debate on potentially negative impacts of cost increasing energy policies on international competitiveness we use firm level data from three countries with similar industry structure but different energy policies germany switzerland and austria we rely on firm manager assessments on the relevance of energy policy in terms of taxes regulations standards subsidies and demand stimulation for their firm operation and link data on the adoption and development of new energy technologies regression analyses and matching approaches both show very few impacts of energy policy on export performance suggesting that either policy impacts on firms cost are negligible in the period of study 2012 to 2014 or likely negative impacts are balanced by the adoption of new technology

environmental innovations and profitability how does it pay to be green an empirical analysis on the german innovation survey much of the empirical literature analysing the relation between environmental innovation and competitiveness has focused on the question whether it pays to be green we differentiate between different types of environmental innovations which will be disentangled in those aiming at reducing the negative externalities and those allowing for efficiency increases and cost savings what we analyze is at first the extent to which these two typologies have impacts on firms profitability with opposite signs and secondly whether the motivations driving the adoption of those innovations make the difference in terms of economic gains we find empirical evidence that both the typology of environmental innovation and the driver of their adoption affect the sign of the relationship between competitiveness and environmental performance the empirical strategy is based on a sample of german firms and makes use of a merge of two waves of the mannheim innovation panel in 2011 and 2009 that allow overcoming some endogeneity issues which may arise in a cross section setting

co2 gdp and ret an aggregate economic equilibrium analysis for turkey there is a worldwide interest in renewable electricity technologies rets due to growing concerns about global warming and climate change as an eu candidate country whose energy demand increases exponentially turkey inevitably shares this common interest on ret this study using an aggregate economic equilibrium model explores the economic costs of different policy measures to mitigate co2 emissions in turkey the model combines energy demands capital requirements and labor inputs at a constant elasticity of substitution under an economy wide nested production function growing energy demand triggered by economic growth is met by increased supply and initiates new capacity additions investment into ret is encouraged via the incorporation of a endogenous technological learning through which the ret cost declines as a function of cumulative capacity and b a willingness to pay wtp function which imposes the wtp of consumers as a lower bound on ret installation the wtp equation is obtained as a function of consumer income categories based on data gathered from a pilot survey in which the contingent valuation methodology was employed the impacts of various emission reduction scenarios on gdp growth and ret diffusion are explored as expected ret penetration is accelerated under faster technological learning and higher wtp conditions it is found that stabilizing co2 emissions to year 2005 levels causes economic losses amounting to 17 and 23 of gdp in the years 2020 and 2030 respectively

the impact of environmentally friendly innovations on value added while recent literature has focused on explaining the determinants of green innovations it is not well understood how such innovations affect performance to analyse the relationship between green innovation and performance new industry level panel data were exploited these include 12 oecd countries the whole manufacturing sector and a period of 30 years the results show that green inventions are u shape related to performance however the turning point is quite high and hence only relevant for a few industries this indicates that given the current level of green promotion market incentives alone are not sufficient to allow the green invention activities of industries to rise considerably to verify these results and to get a better understanding of the mechanisms in the green market we finally made several interviews with multinational firms that have a good understanding of what happens on the global market of green innovation

environmental policy design innovation and efficiency gains in electricity generation this paper explores the relationship between environmental regulation innovation and competitiveness drawing upon a unique dataset on environmental regulations directed at combustion plants a global dataset of power plants and a global dataset of environmental patents the analysis is conducted in two stages first a nonparametric frontier analysis is implemented to estimate efficiency scores including a measure of technological innovation based on patent stocks second econometric methods are applied to analyse the role of policy stringency and policy design on efficiency our estimation sample covers thermal power plant sectors in 20 countries from 1990 to 2009 the results show that the stringency of environmental regulations is a significant determinant of productive efficiency with respect to pollutant emissions as well as fuel use however these effects turn negative once the level of stringency leaps over a certain threshold in addition the paper concludes that the positive effect of regulatory stringency can be diminished by a negative effect of regulatory differentiation with measures which are differentiated across plant size and age having negative consequences and these effects are increasing over time this finding is important given the prevalence of size and vintage differentiated policies in many countries finally it is found that integrated approaches to environmental innovation are more likely to bring about efficiency improvements than end of pipe technologies

investigating policy and r d effects on environmental innovation a meta analysis in the last decades a wide research effort has been devoted at the analysis of the determinants of environmental innovation ei whereas agreement seemed to emerge around a cluster of determinants mainly technology push market pull policy push pull and firm specific factors empirical analyses have failed to provide strong confirmation on the relevance of some core variables after a qualitative discussion of this literature we empirically assess it by exploiting meta regression analysis techniques to test the effectiveness of two determinants policy and r d our findings are clear as for the first we show that only certain types of policy have proven to affect ei in particular regulatory stringency as for r d we show that the use of estimation methods is not neutral to the outcome of the primary studies

what is it about organic milk an experimental analysis auction experiments were used to examine demand relationships and willingness to pay wtp for organic rbst free no antibiotics used and conventional milk elasticities showed strong substitute and complement relationships between organic rbst free and no antibiotics varieties the sum of the latter two s premiums were not significantly different than the organic premium suggesting diminishing marginal utility for added attributes results from a two stage heteroskedastic tobit model demonstrated that wtp premiums for the varieties differ significantly by demographics and beliefs regarding the conventional version these suggest market segments for rbst free and no antibiotics versions could succeed alongside organic benefiting consumers and producers copyright 2007 oxford university press

development and utilization of energy related technologies economic performance and the role of policy instruments the present study investigates the effects of energy related technologies on economic performance at firm level we distinguish clearly between adoption and use of energy related technologies process innovation in the broad sense and product innovation in energy related fields we take into consideration four energy related policy instruments and expected demand for energy related new products and services we investigate the possibility of indirect effects of policy on performance via adoption or innovation by interacting adoption and innovation variables with policy instrument dummies we test our hypotheses not only for the pooled data but also separately for the three countries austria germany switzerland that are taken into consideration in this study we find a positive direct effect of investment expenditures for energy related technologies on labour productivity that measure intensity of adoption of energy related technologies and a positive indirect effect of energy taxes via investment in energy related technologies further we find positive direct and indirect effects of regulation standards and voluntary agreements via the adoption of production related technologies and for technologies for the generation of renewal energy sources we find neither direct nor indirect effects of the sales of innovative energy related products that measure product innovation in energy related products on labour productivity no differences among the three countries could be detected with respect to investment in energy related technologies and sales of innovative energy related products the indirect effects of regulation and standards and voluntary agreements can be primarily traced back to german firms

the innovation effects of environmental policy instruments a typical case of the blind men and the elephant abstract in this paper we examine the innovation effects of environmental policy instruments in four literatures theoretical models on incentives for eco innovation econometric studies based on observed data survey analysis based on stated information and technology case studies the aim of this paper is to critically examine the methods and the results we argue that the case studies literature even when its results are specific and difficult to generalise is a necessary source of empirical evidence about policy impacts and the factors responsible for these impacts pointing to issues that are neglected in the theoretical and econometric literature such as the specifics of the innovation context and policy interaction effects the paper states five synthesised findings and makes a plea for multi method analysis one other important synthesised finding is that the influence of market based instruments on innovation such as emission trading and taxes is far weaker than assumed

environmental innovations in services manufacturing services integration and policy transmissions abstract this paper investigates the relevant factors behind the almost unexplored realm of environmental innovation in services using a dataset of 8161 italian service firms specifically we test whether manufacturing services integration matters for environmental innovations in addition taking account for the heterogeneity of the service industries we analyse whether environmental policies for manufacturing transmit induced innovation effects to services our findings show that i the drivers of environmental innovations related to carbon abatement and energy efficiency differ across industries and ii cooperation training environmental management systems and public funding play key roles in these processes the integration of services and manufacturing through push and pull effects and the environmental policy transmission effect from manufacturing to services generally do not seem to have a positive impact on the diffusion of environmental innovations

induced innovation and energy prices this paper uses u s patent data from 1970 to 1994 to study the impact of energy prices on energy efficient innovations theories of technological change have focused both on demand side factors which spur innovative activity by increasing the value of new innovations and supply side factors such as scientific advancements that make new innovations possible data on demand side factors are easily obtained but data on supply side factors that influence innovation are not readily available this paper uses patent citations as a measure of the usefulness of the existing base of scientific knowledge citations to previous patents are used to construct productivity estimates which measure the usefulness of the existing stock of knowledge to inventors in a given energy field for any given year these estimates are then combined with data on demand side factors to estimate a model of induced innovation in energy technologies the results indicate that both energy prices and the supply of knowledge have strongly significant positive effects on innovation the paper concludes with a discussion of the implication of this work for environmental policy

consumption process and multiple valuation of landscape attributes abstract environmental valuation can be seen as a process which evolves as individuals reflect on their consumption experience in this paper we consider how environmental values could change as the subject has reached the end of the consumption process a split sample comparison is conducted for estimating the values tourists give to a set of landscape attributes the first subsample was taken on site as subjects were on a tour contemplating the landscape of the island of gran canaria canary islands the second subsample was contacted at the airport when individuals were about to leave the tourist enclave since landscapes are complex environmental goods we utilize and compare a multiple contingent valuation cv approach with the stated preference approach of contingent ranking the results show that the influence of the consumption experience depends on the valuation method and the consideration of interaction effects in the model the valuation functions were not stable across both sites for most of the models considered and some of the attributes changed their values between the two points of the consumption process interaction effects were more relevant with the contingent ranking model suggesting that cv is a more limited approach in a context of multiple valuation

the effect of within sector upstream and downstream energy taxes on innovation and productivity the aim of this paper is to investigate the effect of environmental regulatory stringency on innovation and productivity using a panel of 8 european countries for 13 manufacturing sectors over the years 2001 2007 this research topic falls under the heading of the porter hypothesis ph of which different versions have been tested we consider both the strong and the weak versions of the ph while also adding some peculiar features to the analysis firstly we assess the role played by environmental taxes that is an instrument rarely tested as a factor which can support the ph secondly we analyse not only the effect of environmental taxes within a given sector within sector but also the role played by environmental taxes in upstream and downstream sectors in terms of input output relationships thirdly we test these relationships also indirectly by verifying whether innovation is one of the channels through which higher sectoral productivity can be achieved by imposing tighter environmental regulations our main findings suggest that downstream stringency is the most relevant driver of innovation and productivity while within sector regulations only affect productivity but not innovation moreover the effect of regulations on productivity is mostly direct while the part of the effect mediated by induced innovations as measured by patents is relevant only for what concerns downstream regulations

upstream and downstream pollution taxations in vertically related markets with imperfect competition when two markets are vertically related the government can control pollution at the upstream as well as the downstream market levels this paper employs the stylized model of input price discrimination and compares the effectiveness of upstream and downstream pollution taxations we consider the situation in which downstream firms have heterogeneous abatement technologies and an upstream monopolist performs input price discrimination against them in order to mitigate pollution the government imposes input tax on the intermediate inputs and emission tax on the pollutant we show that the degree of input price discrimination decreases with a rise in the input tax and increases with a rise in the emission tax we further examine the effect of a green tax reform in which the government changes the source of taxation from input tax to emission tax we argue that although this green tax reform may reduce the tax revenue of the government it will certainly increase social welfare

auction design in day ahead electricity markets competition in day ahead electricity markets has been established through auctions where generators and loads bid prices and quantities different approaches have been discussed regarding the market auction design multi round auctions despite its implementation complexity allow market participants to adapt their successive bids to market prices considering their operational and economic constraints however most of the day ahead electricity market implementations use noniterative single round auctions this paper presents a market simulator to compare both auction models different auction alternatives such as the spanish single round auction that takes into account special conditions included in the generator bids and multi round auctions with different stopping rules are analyzed the results and acquired experience in the simulation of the spanish market started in january 1998 are presented hourly market prices average daily price price demand correlation and several economic efficiency indicators such as generator surplus consumer surplus and social welfare are compared to derive conclusions regarding the performance of the auction alternatives

redefining innovation eco innovation research and the contribution from ecological economics while innovation processes toward sustainable development eco innovations have received increasing attention during the past years theoretical and methodological approaches to analyze these processes are poorly developed against this background the term eco innovation is introduced in this paper addressing explicitly three kinds of changes towards sustainable development technological social and institutional innovation secondly the potential contribution of neoclassical and co evolutionary approaches from environmental and innovation economics to eco innovation research is discussed three peculiarities of eco innovation are identified the double externality problem the regulatory push pull effect and the increasing importance of social and institutional innovation while the first two are widely ignored in innovation economics the third is at the least not elaborated appropriately the consideration of these peculiarities may help to overcome market failure by establishing a specific eco innovation policy and to avoid a technology bias through a broader understanding of innovation finally perspectives for a specific contribution of ecological economics to eco innovation research are drawn it is argued that methodological pluralism as established in ecological economics would be very beneficial for eco innovation research a theoretical framework integrating elements from both neoclassical and evolutionary approaches should be pursued in order to consider the complexity of factors influencing innovation decisions as well as the specific role of regulatory instruments and the experience gathered in ecological economics integrating ecological social and economic aspects of sustainable development is highly useful for opening up innovation research to social and institutional changes 2000 elsevier science b v all rights reserved

directional heterogeneity in wtp models for environmental valuation many studies in the stated preference literature on environmental valuation do not include the effects of substitutes and distance in willingness to pay wtp models in spite of the relevance of these effects in aggregation and benefit transfer heterogeneity in the availability of substitutes over space may cause multidirectional distance effects in wtp as a result disregarding this spatial heterogeneity may lead to biased estimators of the distance effect and associated wtp values cameron 2006 in this paper we demonstrate that distance decay is subject to significant directional effects which tend to be related to differences in the availability of substitutes across the study area we apply a straightforward methodology to account for such spatial heterogeneity in choice experiments and assess the effect on wtp for improvements in ecosystem services in a lake district we model distance decay effects whilst controlling for heterogeneity between users and non users and non use related wtp reasons the directional effects result in significantly different wtp estimates different market sizes reflecting the population with positive wtp and differences in total wtp up to 32

determinants of environmental innovation new evidence from german panel data sources abstract in most cases empirical analyses of environmental innovations based on firm level data relied on surveys for one point in time these surveys allow for the inclusion of many explanatory variables such as different policy instruments or the influence of pressure groups but it is not possible to address the dynamic character of environmental innovations this paper uses two german panel databases the establishment panel of the institute for employment research iab and the mannheim innovation panel mip of the centre for european economic research zew to explore the determinants of environmental innovations the econometric estimations show that the improvement of the technological capabilities knowledge capital by r d triggers environmental innovations environmental regulation environmental management tools and general organizational changes also encourage environmental innovation a result that has also been postulated by the famous porter hypothesis

heterogeneous impacts of regulatory policy stringency on the eu electricity industry a bayesian shrinkage dynamic analysis abstract environmental and technical efficiency in the electricity sector is a major focus of regulatory policies aimed at hastening greenhouse gas reduction and lowering energy prices for final consumers understanding the impact of market and environmental regulations on efficiency is crucial for the design and choice of policy packages at the national level the productivity response to regulations depends on unobserved country specific factors that current empirical analyses have not modelled in this framework we analyse the regulation effects on efficiency in the electricity sector for a panel of european union countries we explicitly consider the effects of the environmental regulation along with the market regulation our estimation strategy uses the bayesian shrinkage estimator which can deal with the bias aggregation problem and cross country heterogeneity it allows us to identify the different transmission channels through which regulatory policy is implemented the results highlight divergent behaviours at the country level the direct impacts of the market and environmental regulatory policies on productivity are negative around 2 7 and 2 3 respectively but the countries vary in the degree to which they are able to compensate these negative effects

does environmental performance affect financial performance a meta analysis abstract what do we know about the impact of environmental regulations performance on firm performance after more than three decades of theoretical as well as empirical research the results seem to remain inconclusive some papers suggest that regulations harm firms while others claim that regulations may contribute positively and give an impetus to innovations therefore i examine the heterogeneity in financial environmental performance nexus empirically carrying out a meta regression analysis of 64 outcomes from 37 empirical studies to uncover the underlying factors which can influence the observed variation in the empirical results the results suggest both that the empirical method used matters for the nexus and that the likelihood of finding a negative link between environmental and financial performance significantly increases when using simple correlation coefficients instead of more advanced econometric analysis the results also indicate that the portfolio studies tend to report a negative link between environmental and financial performance this likely reflects the omitted factors in portfolio studies the positive link is found more frequently in common law countries than in civil law countries the results also point to the importance of appropriate time coverage to establish a positive link between environmental and financial performance

valuing the multidimensional impacts of environmental policy theory and methods a theoretically consistent framework is developed for valuing the multidimensional impacts of environmental policy conventional benefit estimates are shown to be biased because of the presence of substitution and complementarity effects in valuing policy impacts procedures are developed for implementing a valid framework consistent with theory empirical results indicate significant substitution effects in valuing environmental conditions across different geographic regions

simulating oligopolistic pool based electricity markets a multiperiod approach this paper simulates a pool based electricity market and identifies equilibrium patterns a multiperiod framework that requires the use of continuous and binary variables is considered producers can be either price takers or price makers although price makers and their behavior characterize the market the elasticity of the loads is modeled through piecewise constant price demand curves the market operator uses a detailed network constrained market clearing auction that results in hourly market clearing prices the behavior of the market participants and the market itself are characterized through a repetitive simulation procedure the tool presented in this paper is particularly useful for the market regulator that may use it to monitor the market and to identify the exercise of market power by producers results from a realistic case study are presented and discussed

auction implementation problems using lagrangian relaxation lagrangian relaxation lr is used as an auction method for bidding in a deregulated environment this paper focuses on the problems that occur while using lr as an auction method identical or similar units can prevent lr from finding the optimal solution if the units are similar lr may have trouble selecting some of them for the optimal solution a feasible solution may thus not be found since a heuristic selection of which unit data to alter has to be applied this is inequitable to the unit s not selected and may result in lawsuit s because the dispatcher has to use heuristic selection there is no fair solution to these problems the authors suggest previously published methods to implement auctions sensitivity analysis has also been applied in this paper to show that the percentage difference of similarity between units may affect the solution found

environmental regulation and the export dynamics of energy technologies abstract the pollution haven hypothesis affirms that an open market regime will encourage the flow of low technology polluting industries toward developing countries because of potential comparative advantages related to low environmental standards in contrast the hypothesis suggested by porter and van der linde claims that innovating firms operate in a dynamic competitive situation which allows global diffusion of environmental friendly technologies environmental regulation may represent a relevant mechanism through which technological change is induced in this way countries that are subject to more stringent environmental regulations may become net exporters of environmental technologies this paper provides new evidence on the evolution of export flows of environmental technologies across different countries for the energy sector advanced economies particularly the european union have increasingly focused on the role of energy policies as tools for sustaining the development path the kyoto protocol commitments together with growing import dependence on energy products have brought attention to the analysis of innovation processes in this specific sector the analysis uses a gravity model in order to test the determinants and the transmission channels through which environmental technologies for renewable energies and energy efficiency are exported to advanced and developing countries our results are consistent with the porter and van der linde hypothesis where environmental regulation represents a significant source of comparative advantages what strongly emerges is that the stringency of environmental regulation supplemented by the strength of the national innovation system is a crucial driver of export performance in the field of energy technologies

price taker bidding strategy under price uncertainty this paper provides a framework to obtain the optimal bidding strategy of a price taker producer an appropriate forecasting tool is used to estimate the probability density functions of next day hourly market clearing prices this probabilistic information is used to formulate a self scheduling profit maximization problem that is solved taking advantage of its particular structure the solution of this problem allows deriving a simple yet informed bidding rule results from a realistic case study are discussed in detail

technology diffusion with market power in the upstream industry this paper compares taxes and tradable permits when used to regulate a competitive and polluting downstream industry that can purchase an abatement technology from a monopolistic upstream industry second best policies are derived for the full range of the abatement technology s emission intensities and marginal abatement costs the second best permit quantity can be both above or below the socially optimal emission level explicit consideration of the output market provides further insights on how market power distorts the allocation in the downstream industry the ranking between permits and taxes is ambiguous in general but taxes weakly dominate permits if full diffusion is socially optimal in addition it is analysed how a cap on the permit price affects the diffusion of an abatement technology

determinants of environmental innovation in us manufacturing industries abstract this paper provides new evidence on the determinants of environmental innovation we employ panel data models to study how environmental innovation by us manufacturing industries responded to changes in pollution abatement expenditures and regulatory enforcement during the period 1983 through 1992 we find that 1 environmental innovation as measured by the number of successful environmental patent applications granted to the industry responded to increases in pollution abatement expenditures however 2 increased monitoring and enforcement activities related to existing regulations did not provide any additional incentive to innovate we also find some empirical evidence that environmental innovation is more likely to occur in industries that are internationally competitive

green technologies and environmental productivity a cross sectoral analysis of direct and indirect effects in italian regions abstract this paper provides empirical investigation of the effects of environmental innovations eis on environmental performances as proxied by the environmental productivity ep measure we focus on sectoral environmental productivity of italian regions by exploiting the regional accounting matrix including environmental accounts regional namea patent applications have been extracted by the patstat database and assigned to the environmental domain by adopting different international classifications of green technologies the latest release of the oecd env tech indicators and the union of this with the previously established wipo green inventory econometric results outline that regions sectors characterized by higher levels of green technologies gts are those facing better environmental performance these positive effects directly stem from the introduction of gt in the same sector as well as from the introduction of gt in vertically related sectors

contingent valuation and the activation of environmental norms abstract this paper uses contingent valuation cvm as the context in which to explore the implications of a model of altruistic norm activation a model is presented which provides a framework for thinking about the factors that individuals consider when formulating their responses to cvm questions and the processes by which they bring such factors together the activation of personal environmental norms and hence positive willingness to pay depends on four main categories of belief awareness and acceptance of environmental need consequences of personal action responsibility for personal action and acceptance of policy initiatives the model is illustrated with a qualitative case study and some of the implications for cvm are considered in light of these findings it is argued that whilst notions of fairness may not present problems from a demand prediction economic standpoint such notions may be more problematic for the cost benefit analysis use of results

beyond does it pay to be green a meta analysis of moderators of the cep cfp relationship review of extant research on the corporate environmental performance cep and corporate financial performance cfp link generally demonstrates a positive relationship however some arguments and empirical results have demonstrated otherwise as a result researchers have called for a contingency approach to this research stream which moves beyond the basic question does it pay to be green and instead asks when does it pay to be green in answering this call we provide a meta analytic review of cep cfp literature in which we identify potential moderators to the cep cfp relationship including environmental performance type e g reactive vs proactive performance firm characteristics e g large vs small firms and methodological issues e g self report measures by analyzing these contingencies this study attempts to provide a basis on which to draw conclusions regarding some inconsistencies and debates in the cep cfp research some of the results of the moderator analysis suggest that small firms benefit from environmental performance as much or more than large firms us firms seem to benefit more than international counterparts and environmental performance seems to have the strongest influence on market measures of financial performance

environmental innovations and firm profitability unmasking the porter hypothesis we examine impacts of different types of environmental innovations on firm profits following porter s sci am 264 4 168 1991 hypothesis that environmental regulation can improve firms competitiveness we distinguish between regulation induced and voluntary environmental innovations we find that innovations which do not improve firms resource efficiency do not provide positive returns to profitability however innovations that increase a firm s resource efficiency in terms of material or energy consumption per unit of output have a positive impact on profitability this positive result holds for both regulation induced and voluntary innovations although the effect is greater for regulation driven innovation we conclude that the porter hypothesis does not hold in general for its strong version but depends on the type of environmental innovation our findings rest on firm level data from the german part of the community innovation survey 2008 cis 2008

a simulation model for a competitive generation market the simulation of a wholesale electricity market should go beyond a simple optimization based on the operating costs of the generating units a model of a competitive electricity market must consider the market structure the strategy of the market participants and any other factor that lead to prices different from costs this paper presents cosmee a model of a wholesale electricity market based on simple bids that estimates expected bid prices and quantities system hourly prices and generation schedules taking into account the bidding strategies of generators and the structure of the market the model reflects the profit maximizing behavior of the market agents subject to different types of constraints cosmee has been used to simulate a real wholesale market

a comparison of stated preference methods for environmental valuation this paper presents an empirical comparison of contingent valuation cvm and choice experiments which are used to value environmental quality changes both of these methods require individuals to state their preferences for environmental qualities however choice experiments differ from cvm in that environmental attributes are varied in an experimental design which requires respondents to make repeated choices between bundles of attributes the empirical application involved the effect of environmental quality changes arising from forest management practices on recreational moose hunting values significant differences were found between the values derived from the two methods however detailed examination of the implied choice behaviour suggested that respondents ignored substitute recreation areas in the cvm question restricting the choice experiment model to consider only the one site where quality was varied resulted in welfare estimates similar to the cvm model this highlights the importance of substitutes in environmental valuation and suggests that choice experiments may be more appropriate than cvm in some cases
