integrating methods for ecosystem service assessment and valuation mixed methods or mixed messages a mixed method approach was used to assess and value the ecosystem services derived from the dogger bank an extensive shallow sandbank in the southern north sea three parallel studies were undertaken that 1 identified and quantified where possible how indicators for ecosystem service provision may change according to two future scenarios 2 assessed members of the public s willingness to pay for improvements to a small number of ecosystem services as a consequence of a hypothetical management plan and 3 facilitated a process of deliberation that allowed members of the public to explore the uses of the dogger bank and the conflicts and dilemmas involved in its management each of these studies was designed to answer different and specific research questions and therefore contributes different insights about the ecosystem services delivered by the dogger bank this paper explores what can be gained by bringing these findings together post hoc and the extent to which the different methods are complementary findings suggest that mixed method research brings more understanding than can be gained from the individual approaches alone nevertheless the choice of methods used and how these methods are implemented strongly affects the results obtained

the investor specific price of renewable energy project risk a choice experiment with incumbent utilities and institutional investors abstract renewable energy investments in germany have recently soared trebling the output of wind and solar power generation in only ten years while incumbent utilities have lagged behind in terms of investment new entrants have significantly contributed to this growth existing literature has primarily focused on explaining the lethargy of incumbents former investments although there is a growing need to investigate recent investment drivers to secure the necessary power plant capacity at a moderate cost from incumbents and new entrants alike to close this gap a choice experiment involving 1 659 investment choices by 52 european professional investors was conducted in significant contrast to the case with altruistic investors this survey underlines the importance of using financial incentives to attract professional investors given full exposure to electricity price risk incumbent utilities would facilitate projects at a 3 04 risk premium whereas institutional investors demand 6 61 generally incumbent utilities and institutional investors are equally attracted by low risk projects however when risk increases institutional investors are more hesitant to become involved while incumbent utilities confidently navigate these higher risk projects

modeling a multi attribute utility newsvendor with partial backlogging abstract traditional newsvendor models usually focus on single profit maximization or cost minimization approaches however making a monetary estimate of the consequences of lost sales as a result of shortages is often a difficult task for many practitioners besides there is still a lack of an explicit account of decision making judgments on the multiple consequences of making decisions with regard to order quantities in order to deal with this problem this paper presents a multi attribute utility model for the newsvendor problem with regard to profit the impacts of service level on corporate image and on customers goodwill and the impact on the environment arising from the disposal of unsold products demand is partially backlogged according to a decreasing exponential function of the waiting time the fundamental principles and limitations related to the application of the model built are also discussed

what aspects of formality do workers value evidence from a choice experiment in bangladesh this study uses a choice experiment among 2 000 workers in bangladesh to elicit willingness to pay wtp for job attributes a contract termination notice working hours paid leave and a pension fund using a stated preference method allows calculation of wtp for benefits in this setting despite the lack of data on worker transitions and the fact that many workers are self employed which makes it difficult to use revealed preference methods workers highly value job stability the average worker would be willing to forego a 27 percent increase in income to obtain a 1 year contract relative to no contract or to forego a 12 percent increase to obtain thirty days of termination notice there is substantial heterogeneity in wtp by type of employment and gender women value shorter working hours more than men while government workers place a higher value on contracts than do private sector employees

differences between continuous and discrete contingent value estimates in a split sample contingent valuation study of willingness to pay wtp for food safety improvements the dichotomous choice dc elicitation method consistently generated much larger estimates of wtp than did a continuous method little or none of these differences was due to bias introduced by the statistical techniques used with the dc data most or all of the difference was due to differences in respondent behavior in addition the continuous wtp responses showed a significant scope effect while the dc responses did not the observed difference in behavior may be attributable in part to yea saying by dc respondents

heterogeneity in preferences for woody biomass energy in the us mountain west abstract millions of acres of public forest in the us mountain west are substantially degraded and are in need of restoration mechanized restoration treatments can improve forest health and reduce the likelihood of severe wildfire these treatments produce some timber and substantial amounts of forest residues that can be used to generate renewable energy and displace fossil fuels using the choice modeling method this study investigates social preferences for generation of energy with woody biomass produced by restoration treatments on public forests in the mountain west both multinomial logit and latent class logit lcl models are fit to the data and used to estimate marginal willingness to pay mwtp for increased amounts of woody biomass energy generation and important associated co benefits and costs positive and statistically significant mwtp is found for the number of homes powered with wood the extent of healthy forests avoiding increases in the number of large wildfires and local air quality significant heterogeneity was found in respondent preferences for the attributes the heterogeneity can be explained in part by sociodemographic and attitudinal characteristics of respondents the lcl revealed four classes of respondents with distinct preferences revealing conflicting viewpoints toward forest management for woody biomass energy generation

a comparison of contingent preference models i compare the informational efficiencies of contingent rating contingent ranking and two contingent paired comparison methods as alternatives to the referendum contingent valuation method the contingent rating method is hypothesized to be most efficient because ratings convey information on preference intensities and can uniquely represent respondent indifference or ambivalence survey data on hunters ratings of alternative hypothetical hunting trips are used to estimate four alternative indirect utility models from which marginal willingness to pay measures for individual trip attributes are derived model comparison wtp estimates and their confidence intervals confirm the relative efficiency of the contingent rating approach

determining the scale of r d investment for renewable energy in korea using a comparative analogy approach abstract the rising price of fossil energy due to increasing global energy consumption has stimulated investment in renewable energy despite korea s high dependence on foreign energy sources it is well behind other developed countries with regard to renewable energy production this study attempts to develop a reasonable r d investment plan based on the forecasted diffusion of renewable energy in the korean market by analyzing the experiences of other developed countries the german market is selected as the reference case on the basis of its similarity to the korean market the realized data indicate that the growth of technology is proportional to cumulative r d investment a final investment schedule is established based on the goal of meeting the target penetration level the suggested investment plan which differs substantially from the plan recently announced indicates the necessity of more active investment in early stage and supportive policies for r d into renewable energy

pricing and the news vendor problem a review with extensions in the newsvendor problem a decision maker facing random demand for a perishable product decides how much of it to stock for a single selling period this simple problem with its intuitively appealing solution is a crucial building block of stochastic inventory theory which comprises a vast literature focusing on operational efficiency typically in this literature market parameters such as demand and selling price are exogenous however incorporating these factors into the mode l can provide an excellent vehicle for examining how operational problems interact with marketing issues to influence decision making at the firm level in this paper we examine an extension of the newsvendor problem in which stocking quantity and selling price are set simultaneously we provide a comprehensive review that synthesizes existing results for the single period problem and develop additional results to enrich the existing knowledge base we also review and develop insight into a dynamic inventory extension of this problem and motivate the applicability of such models

comparative statics of changes in risk on monotonically and partially responsive kinked payoffs abstract this paper derives two sets of necessary and sufficient conditions on the comparative statics of changes in risk under kinked payoff functions that are monotonically responsive and partially responsive to the realization of risk respectively the former case includes the newsboy problem with backorder the latter case includes the newsboy problem without backorder and under some restrictions also includes the optimal deductible insurance problem some relatively non restrictive conditions derived from the necessary and sufficient conditions reveal that the three problems can be quite different even though they are often viewed in the literature as being congruous these conditions lead to simple predictions of the direction of change in any risk averse agent s optimal choice upon a change in risk without assuming specific functional forms for the utility function

social costs from proximity to hydraulic fracturing in new york state the study reports data from an economic choice experiment to determine the likely welfare impacts of hydraulic fracturing in this case using natural gas extracted by hydraulic fracturing for household electricity data were collected from an internet survey of 515 residents of new york state the welfare analysis indicated that on average households incur a welfare loss from in state hydraulic fracturing as the source of their electricity the evidence suggests that households in shale counties bear more costs from hf electricity than households out of shale counties the average welfare loss is substantive estimated at 40 46 of average household electric bills in shale counties and 16 20 of bills in counties without shale the evidence also suggests that relative proximity to hf well sites also increases cost borne by households

analyzing public preferences and increasing acceptability for the renewable portfolio standard in korea abstract in order to respond to the challenge of climate change similar to other countries korea has announced various policies to vitalize the development and uptake of renewable energy the renewable portfolio standard rps is the most striking example of a policy in this area this study employs a conjoint survey and bayesian mixed logit model to analyze consumer preferences for specific attributes of the rps policy it analyzes households marginal willingness to pay mwtp for the rps with specific attributes and simulates the degree of household acceptability of the policy through a scenario analysis comparison between costs and benefits of implementing the policy is also attempted by analyzing the households mwtp with the actual transition expense of rps implementation incurred by electricity supply companies the simulation results provide implications for improving rps policy implementation households consider the creation of new jobs as the most important policy attribute followed by increase in electricity prices damage to forests reduction in co 2 emissions and length of power outages moreover the korean household is willing to accept an increase of up to 1 39 in its electricity prices relative to 2012 and the median mwtp of each household for rps implementation is krw 734 99 month usd 0 67 month

is individual environmental consciousness one of the determinants in transport mode choice this article models negative impact on the environment as one of the attributes of transport mode by this modelling we are able to examine whether individual environmental consciousness of this impact plays a significant role in his her choice of transport mode a survey data from saito and onohara area in northern osaka of japan is used to estimate the model with the heteroscedastic extreme value specification both of the estimated and simulated results imply that individual environmental consciousness does influence his her decision on transport mode choice in the sample furthermore the likelihood ratio tests indicate that both the utility and scale parameters are not equivalent across sub samples of university commuters research facility commuters and residents the results of the comparison across sub samples suggest that sometimes we may learn more from sub dividing a whole sample into several sub samples if we could distinguish them by their characteristics

using labels to investigate scope effects in stated preference methods insufficient sensitivity to scope variations in the scale of the environmental good on offer remains a major criticism of stated preference methods and many studies fail a scope test of some sort across a range of existing explanations for insensitivity to scope commodity mis specification embedding warm glows there seems to exist no clear conclusion on how to deal with the problem this paper provides an alternative explanation for insufficient sensitivity to scope based on re definition of the determinants of value for environmental goods within an attributes based choice model in the proposed framework respondents willingness to pay need depend not only on physical characteristics of a good but may also depend on the label under which the environmental good is sold in the hypothetical market to investigate this problem a choice experiment study of biodiversity was conducted we find that controlling for the effects of a label in this case national park designation leads to significant increase in the scope sensitivity of welfare measures

a theory of jump bidding in ascending auctions abstract jump bidding is a commonly observed phenomenon that involves bidders in ascending auctions submitting bids higher than required by the auctioneer such behavior is typically explained as due to irrationality or to bidders signaling their value we present field data that suggests such explanations are unsatisfactory and construct an alternative model in which jump bidding occurs due to strategic concerns and impatience we go on to examine the impact of jump bidding on the outcome of ascending auctions in an attempt to resolve some policy disputes in the design of ascending auctions

renewables portfolio individual preferences and social values towards res technologies abstract the massive deployment of renewable energy sources represents a high priority for greece in order to comply with the directive 2009 28 ec on the promotion of the use of energy from renewable sources by 2020 in this perspective aegean islands especially lesvos are endowed with a considerable potential of a portfolio of renewables a fact that the entrepreneurial interest has already been targeted however regulatory attempts for a massive penetration of renewables do not take seriously into account preferences and risk perceptions of local communities where the proposed projects are to be installed the aim of this study is to investigate individual preferences and social values towards specific technologies of renewables in lesvos island we apply an open ended contingent valuation survey in order to analyze factors shaping public attitudes towards a portfolio of renewable technologies and estimate the economic welfare willingness to pay of the preferred technologies we argue that such information is relevant for energy policy design and the establishment of effective measures for the promotion of renewable energy sources

accounting for local impacts of photovoltaic farms the application of two stated preferences approaches to a case study in portugal abstract renewable energy sources for electricity generation are unequivocally more environmentally friendly than the traditional sources but are not impact free given the potential for solar photovoltaic energy to contribute to the energy mix in some countries it is timely to carefully consider the potential environmental costs of operation of photovoltaic farms which are experienced by the local population while the general benefits accrue to all we apply the contingent valuation method to a sample of local residents close to three selected photovoltaic farms in portugal also we design a discrete choice experiment to elicit the valuation of specific adverse impacts of electricity generation through photovoltaic energy by national residents our results show that the value elicited in the vicinity of the photovoltaic farms is non negligible on the other hand national residents ponder the trade offs implied by the choice sets and value positively the different adverse local impacts both of these estimates in conjunction or independently can be used to fully account for this often neglected cost of solar energy furthermore we argue that when studying the public acceptance of renewables using stated preference methods explicitly presents the trade offs between negative impacts and costs contributing to more realistic portrayal of public opinion

wind power externalities a meta analysis this study presents the first quantitative meta analysis of the non market valuation literature on the external effects associated with wind power production a data set of 60 observations drawn from 32 studies is constructed the relative economic values of different types of externalities as well as the impact of various methodological and sample characteristics on welfare estimates are examined the results indicate a significant effect of visual externalities on welfare estimates in both directions i e a positive effect of visual improvements and a negative effect of deteriorations this finding corresponds to predictions of the importance of visual impacts in the social science literature external effects of wind power on biodiversity mainly birds do not affect welfare estimates indirect externalities caused by conventional sources of electricity that can be avoided by wind power such as a the reduction of air pollution do neither have a significant impact on welfare measures methodologically we find substantial but inelastic income effects and for choice experiments clear evidence of sensitivity to scope from a policy point of view our results suggest that a policy mix combining a promotion of wind turbines with another green policy facilitates expansion of wind energy

are citizens willing to pay for agricultural multifunctionality agricultural multifunctionality is the recognition of the joint exercise of economic environmental and social functions by the agricultural sector in order to make the concept operative for the design of public policies it is necessary to estimate the social demand for such functions the main objective of this article is to present an empirical application in this sense for this purpose we have adopted the agricultural system of cereal steppes in tierra de campos in spain as a case study the economic valuation technique used is the choice experiment the results suggest the existence of a significant demand for the different functions although the demand is heterogeneous depending on the socioeconomic characteristics of the individuals surveyed

a note on the effect of optimal advertising on the distribution free newsboy problem abstract recently lee and hsu 2011 study the advertising effect on the distribution free newsboy problem in one of their results they show that the optimal expenditure on advertising the optimal order quantity and the optimal lower bound on the expected profit increase with the advertising effect parameters although this result holds in general it requires additional assumptions in this note we provide the necessary and sufficient conditions under which the statements of lee and hsu 2011 hold these conditions are shown to be violated if the advertising expenditure is too low or there is a very small difference between the optimal profit and the profit without advertising

green electricity investments environmental target and the optimal subsidy abstract we investigate the optimal investment decision in renewables under market demand uncertainty in the context of the italian strategy for renewable deployment under the eu policy the firm has to decide about the time and size of the investment we find that a higher subsidy level induces the firm to invest earlier with a smaller investment capacity this implies that a given environmental target cannot be reached by a too high too low subsidy level since this will cause the investment level to be too low too late we show that there exists an optimal intermediate subsidy level due to uncertain demand in some cases ensuring to reach the environmental target in time requires an additional conditional subsidy we propose a heuristic for policy makers stating when and how much subsidy to provide furthermore we find that in a more uncertain economic environment the subsidy adjustment to maintain the target level of investment results in the firm investing earlier which is opposite to the standard real options result

robust price setting newsvendor model with interval market size and consumer willingness to pay we consider a price setting newsvendor problem with partial information the newsvendor does not know the price dependent probability distribution of demand but is able to estimate lower and upper limits of the market size and consumer willingness to pay the objective is to minimize the maximum loss in expected profit or minimax regret we derive closed form expressions for optimal quantity and price and identify managerial insights

a bayesian approach to determine the value of information in the newsboy problem abstract the potential benefits of demand forecasting in a newsboy problem are to decrease the risk of overstocking or shortage but forecasting is usually not free in this paper a model to help the decision maker in a newsboy problem to assess the value of information is presented first two cases on available demand information are considered to develop an upper bound of the cost that the decision maker would spend on forecasting then a bayesian approach to forecasting is proposed and evai the expected value of additional information is computed to help the decision maker in deciding whether to use the extra information finally the relationship between the evai and model parameters is discussed

wind farm externalities and public preferences for community consultation in ireland a discrete choice experiments approach abstract in ireland the deployment of onshore wind turbines has become progressively more difficult in some areas because of the potential negative externalities associated with their operation using a discrete choice experiment dce we employ a willingness to accept framework to estimate the external effects of wind turbines on local residents with the inclusion of community consultation and to quantify the compensation required to permit wind farms to be built in ireland our findings reveal that the majority of respondents are willing to make monetary tradeoffs to allow for wind power initiatives and we find that respondents require less compensation if provision is made for a community representative and setback distance is increased

the effect of advertising on the distribution free newsboy problem abstract advertising is very important for the newsboy problem because the shelf life of the newsboy product is short and advertising may increase sales to avoid overstocking in this paper models to study the effect of advertising are developed for the distribution free newsboy problem where only the mean and variance of the demand are known as in khouja and robbins 2003 it is assumed that the mean demand is an increasing and concave function of advertising expenditure three cases are considered 1 demand has constant variance 2 demand has constant coefficient of variation and 3 demand has an increasing coefficient of variation this paper provides closed form solutions or steps to solve the problem numerical results of the model are also compared with those from other papers the effects of model parameters on optimal expenditure on advertising optimal order quantity and the lower bound on expected profit are derived or discussed

transferring economic values on the basis of an ecological classification of nature abstract in order to save research costs economists often try to transfer the economic value of existing nature areas to other planned areas because the existing area and the plan area are not similar such benefit transfers are generally not considered valid although some economists have paid attention to the ecological characteristics of sites in relation to transfers they do not seem to have decomposed ecosystems into spatially homogeneous units which are similar at different locations since ecologists have developed classifications of homogeneous units it is investigated whether it is possible to determine economic values for the elements of an ecological classification of nature which can be transferred from one location to another this investigation is conducted on the basis empirical data collected by means of a cvm survey at different nature reserves on the dutch coast the results indicate that the use of an ecological classification may offer economists new opportunities for transferring economic benefits within a limited geographical area

confidence intervals for evaluating benefits estimates from dichotomous choice contingent valuation studies i evaluate the potential usefulness of nonmarket valuation concepts and techniques from environmental economics for improving wildlife conservation the concepts include distinguishing between on site recreation use value and off site passive use or

willingness to pay lip service applying a neuroscience based method to wtp for green electricity abstract consumers willingness to pay wtp represents a central question for providers of renewable energy most studies on the subject have used contingent valuation and choice experiments however all empirical designs employed to date suffer from serious biases such as strategic behavior we introduce a novel neuroscience based approach to renewable energy related wtp research neuropricing which eliminates some of these biases we tested consumers wtp for two different green electricity products and found wtp for these products to be about 15 above that for a non green electricity tariff our results suggest that neuropricing is indeed able to eliminate strategic behavior moreover this approach allows for wtp studies with much smaller sample sizes than traditional methods require the neuroscience methodology can be used by researchers and marketers alike not only for testing the effects of product attributes on wtp but also for evaluating wtp effects of specific messages in marketing communications thus it may lead to a better understanding of consumer behavior and hence facilitate more successful marketing of renewable energy

robust inventory decision under distribution uncertainty a cvar based optimization approach abstract we study the robust inventory decision making problem faced by risk averse managers with incomplete demand information in a newsvendor setting three basic models are developed expected profit maximization cvar based profit maximization and a combination of the two each model is robustly formulated under the assumption of ellipsoid discrete distribution and again under the box discrete distribution each robust model can be mathematically transformed into a second order cone program for ellipsoid uncertainty or into a general convex optimization problem for box uncertainty both transformed problems can be optimally solved directly we offer propositions with proof to show the equivalence of the transformed problems with the original ones numerical examples are given to validate the proposed approach we find that the performances under both ellipsoid and box uncertain distributions are robust finally sensitivity analysis with respect to risk averse levels and trade off coefficients is conducted to validate the proposed models and solution approaches

enhancing renewable and sustainable energy development based on an options based policy evaluation framework case study of wind energy technology in taiwan global warming and climate change have shifted the focus of industrial development towards low carbon renewable energy re as evidence by global efforts to develop re based sustainable energy policies however the generally cost ineffective nature of re investments explains continued governmental subsidies and draft assistance measures to encourage related industrial development reduce research and development r d costs and increase innovativeness besides measures to accelerate supply and reduced demand for energy sustainable energy policies must enact thoroughly planned legal and regulatory mechanisms notable examples of establishing a legal basis for a low carbon society in taiwan include the energy management act renewable energy development bill greenhouse gas reduction act draft and energy tax act draft however such legislative efforts occasionally conflict or compete with each other warranting further integration additionally re technologies are characterized by high r d costs long term planning and high investment risks therefore based on global trends in wind power development and related policy planning this study analyzes the feasibility of implementing management strategies in the development process and the correlations between such strategies additionally the achievements polices functions mechanisms promotion measures and future plans for related renewable and sustainable energy laws in taiwan is thoroughly reviewed an options based policy evaluation framework is also constructed based on governmental administrative considerations moreover the characteristics of options that lead to unforeseen circumstances during the planning of re development policies are discussed allowing us to derive real time response measures with a decision making value results of this study provide a valuable reference for governmental efforts to evaluate the merits and limitations of related policies concisely ultimately facilitating the formulation of re development policies

reconsidering heterogeneity and aggregation issues in environmental valuation a multi attribute approach the economic valuation of complex environmental goods composed of multiple attributes is an expanding field of research in ecological and environmental economics however several issues are still subjects of debate this paper focuses on three of them the linearity of the valuation function in the attributes aggregation criteria for obtaining social values and the heterogeneity of individuals utility functions a methodological approach based on multi attribute utility theory which enables us to contrast the impact of these concerns on the valuation of environmental goods is proposed we employ the methodology to value a protected natural area and from the results obtained we can conclude that the non linearity and the heterogeneity of the individual utility function are relevant aspects of environmental valuation that need to be taken into account when valuing environmental goods

perceptions versus objective measures of environmental quality in combined revealed and stated preference models of environmental valuation abstract this study examines perceptions and objective attribute measures in discrete choice models of recreation site choice behavior these forms of attribute measurement are examined in individual and combined revealed preference stated preference models our results suggest that the model based on perceptions slightly outperforms the models based on objective attribute measures however issues such as the definition of the choice set and the measurement of welfare present significant challenges when using perceptions data

willingness to accept compensation for the environmental risks of oil transport on the amazon a choice modeling experiment abstract this paper looks at the question of whether subsistence level indigenous people place a value on the preservation of ecosystems independent of direct impacts of environmental change such as impacts on their production activities the economics literature generally suggests that non use values don t exist among the poor and in the informal sector of the economy we examine this issue through a choice modeling experiment a survey was conducted of rainforest communities who live on the banks of the amazon river rio solimoes in the vicinity of proposed oil and gas pipelines the data were analyzed in the choice modeling framework revealing relatively high amounts of compensation that were necessary in order to accept the potential ecosystem damages associated with oil transport even if the people were completely compensated for direct damages such as loss of access to productive resources these results suggest that environmental quality is important for its own sake a result that is very different from the implicit assumption among many economists

improved quality setup cost reduction and variable backorder costs in an imperfect production process abstract this paper illustrates the relationship between quality improvement reorder point and lead time as affected by backorder rate in an imperfect production process to reduce the total system cost by optimizing the setup cost lot size lead time reorder point and process quality parameter simultaneously we first consider that the lead time demand follows a normal distribution then we apply the distribution free approach for the lead time demand we prove two lemmas which are used to find optimal solutions for the basic and distribution free models we compare our models with the existing models using numerical examples and show that significant savings over the existing models can be achieved

do hypothetical and actual marginal willingness to pay differ in choice experiments application to the valuation of the environment abstract in this paper we test the validity of choice experiments with donations for environmental projects in particular we test whether or not there are differences in preferences between a hypothetical and an actual choice experiment our experiments indicate no differences in addition internal tests of validity indicate transitive and stable preferences in both experiments although there are some indications of possible learning effects during the experiment

low energy efficiency in rental properties asymmetric information or low willingness to pay abstract asymmetric information may explain low energy efficiency in rented properties energy ratings while a solution to the information problem will only lead to higher efficiency levels if renter s willingness to pay wtp exceeds landlord s investment costs using a sample of renters from one university this paper estimates this wtp using a discrete choice experiment where respondents choose from a hypothetical set of single bedroom apartments that differ according to a number of attributes including the energy rating results show that there is a strong disutility associated with the least efficient properties and that renters will pay significantly more for efficiency improvements at the lower end of the efficiency scale importantly our wtp estimates are calculated in a setting where respondents were informed about the energy rating system prior to choosing and where the rating was shown for every property therefore in order to maximise the impact of energy rating systems policymakers are encouraged to ensure that both these informational characteristics are in place

the public s value for developing ocean energy technology in the republic of korea a contingent valuation study abstract ocean energy is a type of renewable energies and is considered as having a potential power of providing a substantial amount of energy although some forms of ocean energy are developed there is a need for further technological advances to better utilize ocean energy government should take observable actions to compensate for the costs of developing the technology this paper attempts to apply a contingent valuation cv method to obtaining at least a preliminary evaluation of the benefits that ensue from the development of the technology that commercializes ocean energy in the republic of korea overall the cv survey was successfully carried out to elicit the willingness to pay wtp for ocean energy the wtp was statistically significantly estimated from one and one half bounded spike model and the monthly mean wtp estimates was krw 1003 usd 0 9 per household the estimates of the annual benefits to relevant residents amounted to krw 206 4 billion usd 183 8 million

economic evaluation of environmental externalities in china s coal fired power generation abstract serious environmental externalities exist in china s power industry environmental economics theory suggests that the evaluation of environmental externality is the basis of designing an efficient regulation the purposes of this study are 1 to identify chinese respondents preferences for green development of electric power industry and the socio economic characteristics behind them 2 to investigate the different attitudes of the respondents towards pollution and co2 reduction 3 to quantitatively evaluate the environmental cost of china s coal fired power generation based on the method of choice experiments ce and the 411 questionnaires with 2466 data points we found that chinese respondents prefer pm2 5 so2 and nox reduction to co2 reduction and that the environment cost of coal fired power plants in china is 0 30 yuan per kwh in addition we found that the socio economic characteristics of income education gender and environmental awareness have significant impacts on respondents choices these findings indicate that the environmental cost of coal fired power generation is a significant factor that requires great consideration in the formulation of electric power development policies in addition importance should also be attached to the implementation of green power price policy and enhancement of environmental protection awareness

robust inventory management with stock out substitution abstract stock out substitution is a well documented phenomenon that occurs when customers seek a different product as a substitute for their first choice item if it runs out of stock we consider a single period inventory model with limited information regarding the external demands i e mean variance and covariance and focus on identifying the inventory levels that maximize the worst case expected profit we formulate a two stage optimization model the second stage characterizes the worst case joint demand distribution by treating the inventory levels as input parameters and the first stage identifies the optimal inventory levels based on the results of the second stage the closed form solution of the second stage problem is analytically intractable except for two special cases we develop closed form solutions for these two special cases and use them to develop a heuristic for the general case an extensive numerical study over a wide range of parameters indicates that the performance of the heuristic that we develop is nearly optimal we also provide insights into the effects of demand correlation substitution rate and other parameters on the optimal worst case expected profit of the system

robust optimal policies of production and inventory with uncertain returns and demand abstract we consider an inventory and production planning problem with uncertain demand and returns in which the product return process is integrated into the manufacturing process over a finite planning horizon we first propose an inventory control model for the return and remanufacturing processes with consideration of the uncertainty of the demand and returns then a robust optimization approach is applied to deal with the uncertainty of the problem through formulating a robust linear programming model moreover properties on the robust optimization model are studied and an equivalent robust optimization model based on duality theory is obtained which allows the solutions to be derived more efficiently finally we provide a set of numerical examples to verify the effectiveness of the approach and analyze the effects of the key parameters on the solutions

using choice experiments to value the environment this paper we outline the choice experiment approach to environmental valuation this approach has its roots in lancaster s characteristics theory of value in random utility theory and in experimental design we show how marginal values for the attributes of environmental assets such as forests and rivers can be estimated from pair wise choices as well as the value of the environmental asset as a whole these choice pairs are designed so as to allow efficient statistical estimation of the underlying utility function and to minimise required sample size choice experiments have important advantages over other environmental valuation methods such as contingent valuation and travel cost type models although many design issues remain unresolved applications to environmental issues have so far been relatively limited we illustrate the use of choice experiments with reference to a recent uk study on public preferences for alternative forest landscapes this study allows us to perform a convergent validity test on the choice experiment estimates of willingness to pay

an integrated revenue management framework for a firm s greening pricing and inventory decisions abstract there is a growing interest on developing efficient ways of incorporating environmental considerations into business practices in order to meet both consumers demand for green products services and the firms sustainable profitability the main contribution of this article is in developing an integrated revenue management framework to address a firm s greening investment effort pricing and inventory decisions it is assumed that the firm inaugurates a green product along with its existing product even though the firm offers both the green and regular product at differentiated prices the market segmentation as a result of this price differentiation is regarded as imperfect this imperfect market segmentation causes a demand leakage mainly due to the heterogeneity among the customers willingness to pay these effects are included in our proposed model and simplified analytical solutions are developed to solve the same additional scenarios where a firm experiences a price dependent stochastic demand with an unknown distribution is also modeled this scenario is addressed using a distribution free approach based on scarf s rule the performance of the proposed methods and the significance of the modeling framework are finally corroborated through several simulations this analysis provides a sustainable environment production and retailing framework while still augmenting profitability using fundamental tools from revenue management

on the role of discrete bid levels in oral auctions abstract bids in oral auctions are restricted to discrete levels this paper both examines the choice of levels at which bids will be allowed and also presents a simple model of the role of the discrete levels in bidding strategy we consider two different distributions of bidders values identifying cases in which revenue is maximized by increasing intervals by constant intervals and by decreasing intervals moreover conditions under which the choice of bid levels that maximizes bid taker revenue also maximizes economic efficiency are developed we present a model of the economic trade off between auction duration and step size we consider the previously undiscussed issue of when economically motivated bidders should skip bid levels and when they should merely make minimum advances and develop a model in which it is equilibrium behavior always to make the minimum allowed advance

jump bidding strategies in internet auctions abidding strategy commonly observed in internet auctions is that of jump bidding or entering a bid larger than what is necessary to be a currently winning bidder in this paper we argue that the cost associated with entering online bids and the uncertainty about future entry both of which distinguish internet from live auctions can explain this behavior we present a simple theoretical model that includes the preceding characteristics and derive the conditions under which jump bidding arises in a format commonly used for online trading the ascending price auction we also present evidence recorded from hundreds of internet auctions that is consistent with some of the basic predictions from our model we find that jump bidding is more likely earlier in an auction when jumping has a larger strategic value and that the incentives to jump bid increase as competition increases our results also indicate that jump bidding is effective jump bidders place fewer bids overall and increased early jump bidding deters entry later in the auction we also discuss possible means of reducing bidding costs and evidence that internet auctioneers are pursuing this goal

product selection for newsboy type products with normal demands and unequal costs abstract in this paper we consider two newsboy type products with unequal prices and costs both demands are independent and follow normal distributions with unknown parameters and we study the product selection problem which deals with comparing two products and selecting the one that has a significantly higher profitability in which the profitability is defined to the probability of achieving a target profit under the optimal ordering policy the statistical hypothesis testing methodology is performed to tackle this selection problem critical value of the test is calculated to determine the selection decision sample size required for a designated power and confidence level is also investigated an application example on comparing english teaching magazines is presented to illustrate the practicality of our approach

heterogeneous preferences toward landscape externalities of wind turbines combining choices and attitudes in a hybrid model abstract expanding the share of renewable energy sources might substantially increase externalities as for example wind turbines may disturb the landscape and negatively affect biodiversity this paper investigates the public s sensitivities towards these externalities by using discrete choice experiments and shows how preferences differ across inhabitants of our study region as a further insight into the sources for these variations a hybrid choice model is employed in order to incorporate individuals latent attitudes in the estimated model our latent class structure allocates individuals to classes according to underlying latent attitudes that also influence the answers to attitudinal questions we show that these underlying attitudes are a function of a number of socio demographic characteristics with young people men with low income and those living closer to turbines having a stronger pro wind power generation attitude the inclusion of the attitudes in the class allocation component of the latent class model leads to a richer picture of people s valuations revealing for example antagonistic preferences of two distinct groups of respondents i e advocates and opponents of wind power generation

external benefits of waste to energy in korea a choice experiment study abstract the korean government has planned to expand a variety of waste to energy wte facilities in order to reduce waste disposal decrease the crude oil imports and mitigate greenhouse gases ghgs emissions one response to this concern is to measure the external benefits of wte to this end this study attempts to apply a choice experiment ce to four attributes or types of benefits such as the improvement of energy security reduction of ghg emissions job creation and extension of landfill life expectancy a survey of 500 households was undertaken in seoul korea the trade offs between price and the four attributes for selecting a preferred alternative are considered in the ce survey and a marginal willingness to pay mwtp estimate for each attribute is derived a nested logit nl model is employed in this study rather than a multi nomial logit mnl model since two specification tests indicate that the nl model outperforms the mnl model the estimation results for the nl model show that the mwtps for a 1 increase in energy security a 1 reduction in ghg emissions the creation of 10 000 new jobs and the doubling of landfill life expectancy as a result of expanding wte facilities is estimated to be krw 437 usd 4 5 1763 1 5 598 0 5 and 89 0 1 per household per month respectively the findings can provide policy makers with useful information for evaluating and planning wte policies and projects

using choice experiments to investigate the policy relevance of heterogeneity in farmer agri environmental contract preferences agri environmental contracts are used to provide incentives for nature management on private land in e g the european union the aim of this article is to investigate preference heterogeneity for agri environmental contracts among farmers in order to discuss potential policy improvements utilising heterogeneity we used a choice experiment to elicit farmers stated preferences for afforestation contracts four attributes are investigated purpose of afforestation option of cancelling the contract monitoring and compensation level all attributes present a potential conflict between farmers and authorities interests which emphasises the importance of knowing how to handle these interests a random parameter logit model shows that having the option to cancel the contract decreases farmers required compensation level and monitoring increases it furthermore farmers are willing to accept a lower compensation when the aim is to protect biodiversity and ground water relative to recreation latent class models with class probability variables reveal discrete heterogeneity and support a division into four groups with divergent preferences for example a group of farmers who already have forest areas does not find the option of cancelling the contract important whereas another group relying on the farm for income requires higher compensation the findings indicate potential for efficiency gains from targeting the contracts

willingness to pay for renewable energy investment in korea a choice experiment study abstract renewable energy sources are considered as alternatives for coping with the high price of oil and global warming the korean government has set a target that 11 of the total primary energy supply should be obtained through renewable energy sources until 2030 in order to develop proper policies for renewable energy investment it is necessary to analyze the benefits of renewable energy investment based on households willingness to pay this study attempts to apply a choice experiment ce for assessing renewable energy investment in korea moreover we employ a multinomial probit mnp model to relax the assumption that all respondents have the same preferences for the attributes being valued which is usually required in empirical ce studies an mnp model allows the most flexible pattern of error correlation structure the results reveal that the korean public puts a value on the protection of wildlife reduction of pollution and increased employment opportunities on the other hand respondents do not derive significant values from the improvement of landscapes this study is expected to provide policy makers with useful information for evaluating and planning policies related to renewable energy investment

using conjoint analysis to derive estimates of compensating variation abstract we use several approaches to derive estimates of hicksian compensating variation from conjoint ratings data the different estimation approaches produced mixed results with respect to consistency with utility theory statistical significance of key variables magnitude of welfare estimates and confidence bounds on welfare estimates these findings suggest conjoint analyses are not a panacea for the problems being debated regarding contingent valuation and travel cost methodologies and conjoint questions appear to share many of the advantages and disadvantages associated with dichotomous choice contingent valuation questions

renewable electricity as a differentiated good the case of the republic of korea this paper examines the willingness for korean consumers to pay a premium for renewable electricity under a differentiated good framework by applying the contingent valuation method korean consumers have been required to pay for their use of renewable electricity as of 2012 first we find that korean consumers recognise renewable electricity as a differentiated good from traditional electricity generated from fossil fuels or nuclear energy the mean willingness to pay to use renewable electricity is usd 1 26 per month second we confirm the existence of perfect substitution relationships among variant renewable technologies which suggests that korean consumers do not perceive them as differentiated goods one reason for this perception is that korean consumers are more inclined to favour economic feasibility over sustainability or the availability of the resource stock when choosing between renewable technology types in sum we can say that korean consumers recognise renewable electricity as a differentiated good but that they do not differentiate between variant renewable technologies thus the imposition of the cost of renewable electricity on consumers in the form of increased electricity charges would be acceptable to consumers as long as any price rise properly reflects their preferences

silent auctions in the field and in the laboratory we analyze data from hundreds of auctions from three field silent auction sessions we focus on the descriptive statistics and on a parametric model of jump bidding we then report data from six laboratory sessions of silent auctions as a controlled environment this allows us to evaluate the auctions in ways not available within the field the laboratory experiments capture essential features of the field sessions and thus comprise a credible laboratory testbed for further examination of institutional perturbations in the silent auction jel d44 h41

jumping and sniping at the silents does it matter for charities abstract despite its popularity as a fundraiser for charities very little research has been done on the bidding and revenue properties of the silent auction this paper examines the consequences of two behaviors common in silent auctions jump bidding and sniping in laboratory experiments with endogenous participation our results suggest that deliberative jumping the result of impatient bidders attempting to telescope time tends to increase revenue while deliberative sniping by experienced bidders tends to decrease it we also show that when charities can encourage jumping and discourage sniping silent auctions can perform as well as their sometimes more entertaining but more expensive alternative the english auction

valuing financial health and environmental benefits of bt cotton in pakistan data from a farm survey and choice experiment are used to value the benefits of bt cotton in pakistan unlike previous research on the economic impacts of bt which mostly concentrated on financial benefits in terms of gross margins we also quantify and monetize positive externalities associated with technology adoption due to lower chemical pesticide use on bt cotton plots there are significant health advantages in terms of reduced incidence of acute pesticide poisoning and environmental advantages in terms of higher biodiversity and lower soil and groundwater contamination these positive externalities are valued at us 79 per acre of which half is attributable to health and the other half to environmental improvements adding average gross margin gains of us 204 results in an aggregate benefit of us 283 per acre of bt or us 1 7 billion for the total bt cotton area in pakistan

random coefficient models for stated preference surveys abstract this paper combines the use of random coefficient discrete choice models that allow for correlated errors in the form of unobserved preference heterogeneity with an investigation of the reliability and usefulness of rankings data for the data we examine we find significant unobserved preference heterogeneity in the rankings which violates the underlying assumptions of the rank ordered logit model further directly modeling unobserved preference heterogeneity results in significant improvement in the precision of the parameter estimates and in estimated willingness to pay wtp the reliability and usefulness of rankings data should be re examined with econometric models not subject to the independence of irrelevant alternatives iia

the distribution free newsboy problem extensions to the shortage penalty case abstract in the classical newsboy problem no cost is assumed if the ordered quantity is less than the demand however in reality failure to meet demand is always associated with a penalty the aim of this work is to extend the analysis of the distribution free newsboy problem to the case when shortage cost is taken into consideration the analysis is based on the assumption that only the mean and variance of demand are known but its particular probability distribution is not a model is presented for determining both an optimal order quantity and a lower bound on the profit under the worst possible distribution of the demand the following cases are considered the single product case the fixed ordering cost case the random yield case and the resource constrained multi product case

hydropower externalities a meta analysis this paper presents a meta analysis of existing research related to the economic valuation of the external effects of hydropower a database consisting of 81 observations derived from 29 studies valuing the non market impacts of hydropower electricity generation is constructed with the main aim to quantify and explain the economic values for positive and negative hydropower externalities different meta regression model specifications are used to test the robustness of significant determinants of non market values including different types of hydropower impacts the explanatory and predictive power of the estimated models is relatively high whilst controlling for sample and study characteristics we find significant evidence for public aversion towards deteriorations of landscape vegetation and wildlife caused by hydropower projects there is however only weak evidence of willingness to pay for mitigating these effects the main positive externality of hydropower generation the avoidance of greenhouse gas emission positively influences welfare estimates when combined with the share of hydropower in national energy production sensitivity to scope is detected but not linked to specific externalities or non market valuation methods

the distribution free newsboy problem with resalable returns we study the case of a catalogue internet mail order retailer selling style goods and receiving large numbers of commercial returns returned products arriving before the end of the selling season can be resold if there is sufficient demand a single order is placed before the season starts excess inventory at the end of the season is salvaged and all demands not met directly are lost since little historical information is available it is impossible to determine the shape of the distribution of demand therefore we analyze the distribution free newsboy problem with returns in which only the mean and variance of demand are assumed to be known we derive a simple closed form expression for the distribution free order quantity which we compare to the optimal order quantities when gross demand is assumed to be normal lognormal or uniform we find that the distribution free order rule performs well when the coefficient of variation cv is at most 0 5 but is far from optimal when the cv is large

a risk tolerance analysis for a joint price differentiation and inventory decisions problem with demand leakage effect abstract price differentiation is a commonly used practice in revenue management rm to improve a firm s profitability however most studies in the literature have considered a risk neutral firm to demonstrate the benefits of price differentiation the main contribution of this paper is in considering several important objectives while determining the optimal product prices and order production quantities for a risk adjusted firm with demand leakage effects in the presence of a price dependent stochastic demand the objectives considered include the maximization of a firm s expected profit and maximizing the probability of exceeding the risk adjusted expected revenue closed form expressions for optimal product prices and production quantities are derived for several of these objectives a numerical study is also presented to calibrate the impact of a firm s risk tolerance and other factors such as demand leakage market demand variability on the firm s profitability and its optimal decision

robust multi item newsboy models with a budget constraint abstract in this paper we present robust newsboy models with uncertain demand the traditional approach to describing uncertainty is by means of probability density functions in this paper we present an alternative approach using deterministic optimization models we describe uncertainty using two types of demand scenarios namely interval and discrete scenarios for interval demand scenarios we only require a lower and an upper bound for the uncertain demand of each item while for discrete demand scenarios we require a set of likely demand outcomes for each item using the above scenarios to describe demand uncertainty we develop several minimax regret formulations for the multi item newsboy problem with a budget constraint for the problems involving interval demand scenarios we develop linear time optimal algorithms we show that the corresponding models with discrete demand scenarios are np hard and that they are solvable by dynamic programming finally we extend the above results to the case of mixed scenarios where the demand of some of the items is described by interval scenarios and the demand of the remaining items is described by discrete scenarios

altruism spillovers are behaviors in context free experiments predictive of altruism toward a naturally occurring public good abstract this paper addresses the external validity of experiments investigating the characteristics of altruism in the voluntary provision of public goods we conduct two related experiments that allow us to examine whether individuals who act more altruistically in the context free environment are also more likely to act altruistically toward a naturally occurring public good we find that laboratory behavior can be predictive of contributions toward naturally occurring goods but not in a uniform way in fact parametric measures of altruism do a poor job of predicting which subjects are most likely to contribute to a naturally occurring public good

integrated assessment of sustainability trade offs and pathways for global bioenergy production framing a novel hybrid approach abstract current controversies and debates on bioenergy production in the areas of greenhouse gases emission reduction food and energy security social exclusion and welfare erosion and ecosystem deterioration attest to the challenges which the bioenergy sector has to overcome to achieve its global production potentials because it is yet an evolving sector the sustainability of bioenergy production in different regions is very elusive experiences show that bioenergy policies in one region can have impacts not only on its own but also on other regions social economic and ecological sustainability it is thus important to assess development pathways for bioenergy to exploit the potential benefits and forestall any unnecessary costs this paper frames a novel hybrid approach for assessing bioenergy potentials for regions with diverging economic social and ecological systems the approach is based on a conceptual framework that takes into account trade offs decisions on sustainability goals and production options in the assessment of bioenergy pathways it combines different empirical techniques for the systematic investigation of trade offs and pathways including fuzzy logic conjoint logit and path analyses to show the relevance and utility of these techniques for the integrated assessment of trade offs and pathways in bioenergy development we illustrated their application using results and data from previous related studies

an integrated approach to price differentiation and inventory decisions with demand leakage abstract price differentiation is among widely practiced tools in revenue management rm in which a seller offers same or slightly different products or services at different prices to its customers earlier research studies have shown that the benefits from price differentiation are evident when the market segmentation is assumed to be perfect in a perfect market segmentation customers associated with a market segment do not move between market segments however it is not uncommon to observe that a market segmentation a firm operates in is seldom prefect and due to imperfect segmentation customers move between market segments which is also referred to as demand leakage in addition the firms predominantly experience stochastic demand and thus a firm experiences both the short sales and leftovers due to demand uncertainty this research proposes a model to address the issue of an optimal market segmentation using price differentiation as a tool we also establish an integrated framework for pricing order and production quantity allocation decisions in each market segment when a firm experiences demand leakage from one market segment to another and faces price dependent stochastic demand the model is analyzed to determine an optimal decision framework on pricing order quantity allocation and market segmentation using the proposed price differentiation due to the complexity of the problem both the hierarchical and joint optimization approaches are developed a simplified closed form optimal solution to the problem is outlined in the case of hierarchical approach the model is also analyzed for a situation in which the distribution of the price dependent stochastic demand is unknown and a distribution free approach is utilized to address the problem it is identified that the use of distribution free approach also results in a closed form optimal solution to the problem a numerical study is presented to demonstrate the performance of the model and solution approaches the benefits of the optimal market segmentation using a differentiation price are also highlighted along with the proposed integrated optimal decision framework when a firm experiences demand leakage

valuation for renewable energy a comparative review abstract environmental cost benefit analysis is applied for the evaluation of renewable energy projects since some benefits and costs do not have monetary values economic valuation techniques are applied to estimate them this paper reviews the literature on the valuation evaluation of renewable energy resources and summarizes the methods used in them it discerns four main streams of valuation in renewable energy the first is economic welfare oriented and comprises stated and revealed preference methods the second is the financial option analysis with a financial background the third is emergy analysis which is mostly an ecological engineering based method with capable economic links and the fourth is again economic but not welfare based the paper discusses the main directions discerned in these studies and recognizes first that proper valuation takes place only in the first method while the other methods describe only evaluation procedures and second that there is a research gap that has yet to be filled in as compared to other areas of environmental resource and energy economics

the simultaneous ascending auction dynamics of price adjustment in experiments and in the uk3g spectrum auction we develop a model of the behavior of bidders in simultaneous ascending auctions based on two principles principle of surplus maximization and principle of bid minimization these principles lead to models of both price dynamics and equilibration leading to disequlibrium structural equations that can be used for estimating bidder values the intention behind the development of this methodology is to provide an auctioneer a method of extracting information during an auction about possible closing prices we benchmark the performance of the model with data from experimental auctions and then apply it to the uk umts or third generation mobile auction

the impact of choice inconsistencies in stated choice studies a new test procedure revealing mutuallyinconsistent choices has been developed andapplied to stated choice data our analysisshows that inconsistent choices commonly occurin several stated choice tasks an applicationof the test to the norwegian value of timestudy data shows that failing to excludeinconsistent choices resulted in asubstantially higher value of time theinconsistent choices were made by less educatedparticipants as the tasks were undertaken inthe easy context of choosing travelalternatives with three attributes practitioners of more complex and cognitivedemanding designs should be particularilyconcerned with these results

the role of the bidding process in price determination jump bidding in sequential english auctions i introduction standard auction theory predicts that in a private value english oral auction the winner will be the bidder with the highest valuation for the object and the selling price will be the second highest valuation in those auctions a reasonable strategy for a bidder would be to increase each bid by the minimum bid increment this solution is referred to as the ratchet solution straightforward bidding or as pedestrian bidding jump bidding occurs when a new offer is submitted that is above the old offer plus the minimum bid increment permitted in this paper i study the sequence of bidding in an open outcry english auction to examine how strategic bidding affects price determination i do this by examining the nature of jump bidding in data i have collected from a series of public auctions of used cars in new jersey the auction literature has not fully addressed and characterized jump bidding in english auctions the theoretical literature on the conditions under which jump bidding will emerge e g avery 1998 daniel and hirshleifer 1998 easley and tenorio 2004 isaac salmon and zillante 2007 macskasi 2000 rothkopf and harstad 1994 does not include any models of english auctions with affiliated values and discrete bid levels table 1 summarizes the different models predictions the empirical and experimental literature on jump bidding is also quite narrow plott and salmon 2004 isaac salmon and zillante 2005 2007 and isaac and schnier 2005 found support for jump bidding in their studies borgers and dustmann 2005 in analyzing the united kingdom s sale of licenses for third generation mobile telephone services found that although the majority of bids in the auction were the lowest admissible bids there were a significant number of jump bids haile and tamer 2003 also documented jump bidding in a regular english auction and reported that the gap between first and second highest bids is usually above the minimum bid increment allowed section ii provides a detailed literature survey in order to characterize jump bidding and because the auctions i study have no seller s reserve price i define the first jump as the first offer submitted by any bidder the second jump is the difference between the second offer submitted by a bidder and the first offer the last jump is the difference between the winning bid and the previous offer 1 i further define the average jump 2 across all jumps excluding the first and last jumps figure 1 describes these variables graphically i find that jump bidding is a widespread empirical regularity in the sale of all items the jumps depend on the presale estimate of the item s price and are not affected by the selling order for almost all items bidders use jump bidding to increase the current offer furthermore on average the first jump is greater than the second jump which is greater than the average jump which in turn is greater than the last jump i offer several explanations for the existence of jump bidding these findings suggest that there is some strategic bidding behavior in the way bidders advance their bids bidders consider the way the auction progresses which implies that a bidder s strategy includes not only the stopping point along the bidding path but also the precise nature of the path that led there consideration of jump bidding strategy sheds light on whether an open outcry auction is best interpreted with models that assume private or common item valuations under the assumption of independent private values bidding history should not affect the point at which a bidder drops out this is not the case in a common value auction in which each stage of the auction is used as a device for signaling the selling price in an english auction with common values will be path dependent hence a simple test of the effect of the first jump on the selling price determines the type of the auction

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
