models for referendum data the structure of discrete choice models for contingent valuation abstract in 1979 bishop and heberlein introduced an appealing variant of the contingent valuation method which required only yes or no responses hanemann developed a utility theoretic interpretation of the yes no responses which has helped popularize the approach recently cameron has offered another interpretation also utility theoretic which she argues is more general than the hanemann random utility model this paper compares the deterministic models suggested by hanemann and cameron showing them to be dual to each other it shows that correct specification of either function must exclude endogenous variables such as quantity demanded it also demonstrates that using utility theoretic models allows one to compare travel cost models and contigent valuation models on the basis of their implied behavior not on the unobservable surplus or variation measure

preference uncertainty in stated preference studies facts and artefacts the ordinal scale and polychotomous choice methods are two widely used techniques for estimating preference uncertainty in stated preference studies this article presents the results of two experiments that apply these estimation techniques the first experiment was designed to compare and contrast the scores of the ordinal scale and polychotomous choice method the second experiment was conducted to test a scale that combines verbal expressions with numerical and graphical interpretations a composite scale the results of the study can be summarized in three key findings first the polychotomous choice method generates a higher proportion of yes responses than the conventional dichotomous choice elicitation format second the composite scale generates a significantly higher proportion of certain responses finally the ordinal scale performs poorly on the ground of construct validity

precision of dichotomous choice contingent valuation welfare measures some simulation results the purpose of this research is to examine the roles of individuals heterogeneous economic factors and model misspecification in dichotomous choice contingent valuation welfare measurement willingness to pay for an improvement of environmental quality is studied simulation results indicate that the precision of welfare estimates increases with individuals income levels and decreases with the price of the quality related good the dependence of the consumption of the quality related good on the environmental quality also affects the reliability of welfare estimates

treatment of don t know responses in contingent valuation surveys a random valuation model abstract this paper provides a utility theoretic interpretation of don t know dk responses in contingent valuation surveys using a referendum elicitation procedure the random valuation model in this paper assumes that each respondent of a contingent valuation survey has an implicit valuation distribution rather than a single true value as traditionally assumed in his her mind if an offered referendum bid is not clearly different from the mean value of one s valuation distribution the respondent may give a dk answer to the cv referendum question based on this model a maximum likelihood procedure is proposed for estimating respondents willingness to pay for a nonmarket good with referendum contingent valuation data which include dk responses an empirical illustration of this estimation procedure is also provided

taste for diversity and the optimality of economic growth abstract we disentangle the taste for diversity in consumption present in endogenous growth models with expanding product variety from the elasticity of substitution between consumption goods this seriously affects the welfare analysis of the model if taste for diversity is relatively small the market rate of growth may be suboptimally large

sensitivity of willingness to pay estimates to bid design in dichotomous choice contingent valuation models this paper addresses the sensitivity of dichotomous choice contingent valuation method dc cvm based mean willingness to pay wtp estimates to the dc cvm sample design and to alternative measures of wtp this issue is examined both analytically and empirically the analysis of ten different dc cvm data sets revealed a sensitivity in estimated mean wtp to the sample design and to the measure chosen to calculate mean wtp

estimating the precision of welfare measures abstract three methods for constructing standard deviation and or confidence intervals for welfare estimates have been employed in the recreation demand literature a taylor s series approximation the bootstrap and a method proposed by krinsky and robb this paper presents the results of two sets of simulation experiments designed to examine the accuracy of these methods the first simulation examines the methods accuracy in estimating the standard deviation of welfare estimates the second simulation examines the accuracy of the methods in constructing confidence intervals

preservation or use a contingent valuation study of wilderness designation in utah evidence of strong opposition to wilderness proposals in utah suggested that the non market value of retaining those areas in multiple use management might be significant a contingent value analysis of both supporters and opponents of the two major proposals for wilderness designation in utah indicated that there existed significant non market willingness to pay on the part of opponents and that standard contingent valuation practice which does not explicitly consider these values could lead to a mis estimation of aggregate willingness to pay

measuring the economic benefits of recycling the case of the waste agricultural film in korea recently increase of the waste agricultural film waf raises the loss of the resources and produces the environmental damage in korea the korean government has established the basic plan for increasing the recycling rate and abating the environmental damage the objective of this paper is to estimate the economic benefits attached to the policy of recycling the waf using contingent valuation method aiming to provide policy makers with useful information to make an informed public decision in recycling the waf the overall results show that the respondents well accepted the contingent market and would be willing to pay a significant amount for the proposed policy of recycling the waf the mean willingness to pay and the truncated mean willingness to pay per household were 4641 korean won us 3 6 and 5730 korean won us 4 4 respectively total economic benefits for the population amounted to approximately 14 33 billion korean won us 11 02 million per year this quantitative information can be use

the downsian voter meets the ecological fallacy this paper presents evidence that voter participation does not depend on the probability that one vote is decisive an extensive summary of the empirical participation literature is provided which shows that most but not all studies have found that turnout in an electoral district is higher when the race is closer individual level vote regressions for the 1979 and 1980 canadian national elections are estimated using objective measures of closeness as opposed to self reported measures the main finding is that a citizen is no more likely to vote in a close election than in a lands lide election district level turnout regressions for the same elections are also estimated and a significant relation between closeness and turnout is observed this suggests that aggregation bias may generate a spurious closeness turnout relation in district level regressions

voter information and power dilution evidence from sicilian provincial elections it is generally accepted that an increase in the amount of voter information is desirable as reisman 1990 points out a well informed and committed electorate is better able to exercise rational choice and consequently is less likely to have its wishes being thwarted by elected representatives in this connection a crucial question relates to the effect of increased voter information on power of elected representatives in other words does increased voter information dilute or increase the power of political parties from the answer to this question flow numerous conclusions about the size of rents enjoyed by political parties under differing electoral systems

yea saying in contingent valuation surveys a number of recent papers have provided estimates of willingness to pay derived in contingent valuation surveys exceeding those revealed in experimental or real life markets one possible explanation for the overestimation of values is the presence of yea saying with the objective of reducing the occurrence of yea saying a new elicitation format referred to as the dissonance minimizing d m format is proposed an empirical comparison of the dm format with the conventional dichotomous choice dc format and the ambivalence reducing polychotomous choice pc format suggested by ready whitehead and blomquist 1995 is made results are encouraging for the dm

using contingent valuation to value a noxious weeds control program the effects of including an unsure response category the national oceanic and atmospheric administration contingent valuation panel recommended that a response category be included along with the vote in favor and vote against options associated with a referendum contingent valuation question that allows individuals to express lack of a well defined opinion however the recommendation did not include guidance on how to analyze such responses in this article we describe the results of a carefully designed split sample experiment that allowed for comparison of a standard dichotomous choice referendum treatment to a treatment that included the option of responding unsure to the contingent valuation question in addition to the standard vote in favor and vote against response categories we are able to examine several options for dealing with the unsure responses and conclude that the unsure responses should be included in the value estimation as the respondents who choose this response category are distinct from respondents who choose the vote in favor and vote against response categories

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

choice certainty and consistency in repeated choice experiments the main objective of this study is to examine how repeated choice affects preference learning in stated preference experiments we test different hypotheses related to preference learning by analyzing response patterns and asking respondents in a choice experiment to report their experienced certainty when going through the choice tasks in a split sample test we show that follow up choice certainty questions are procedural invariant the self reported certainty results indicate that learning occurs but econometric testing procedures do not identify any significant impact of learning effects on parameter estimates or variance across choice tasks additional tests of choice consistency suggest that preferences in the choice experiment are stable and coherent

a new paradigm for valuing non market goods using referendum data maximum likelihood estimation by censored logistic regression abstract this paper challenges the w m hanemann amer j agr econom 66 332 341 1984 and c sellar j p chavas and j r stoll j environ econom management 13 382 390 1986 utilizations of logit models to estimate the value of non market resources from referendum survey data these data are more informative than conventional choice data the random utility interpretation of logit models is therefore too restrictive bypassing the utility function entirely it will be shown that parameters and standard errors for utility theoretic inverse hicksian demand functions can be extracted directly and much more simply estimated demand functions need not be limited to those corresponding to the linear in parameters utility difference specifications which can be handled by packaged logit programs

disentangling preferences and expectations in stated preference analysis with respondent uncertainty the case of invasive species prevention abstract contingent valuation typically involves presenting the respondent with a choice to pay for a program intended to improve future outcomes such as a program to place parcels into conservation easement or a program to manage an invasive species deducing from these data the value of the good or bad at the core of the program the welfare gain generated by a parcel of conserved land for instance or the loss incurred by a species invasion often is not possible because respondent preferences are conflated with their expectations about future environmental outcomes in the absence of the program this paper formally demonstrates this conundrum in the context of a standard contingent valuation survey and examines the use of additional survey data to resolve it the application is to the prevention of lake invasions by eurasian watermilfoil myriophyllum spicatum an invasive aquatic plant that is present in many lakes in the northern u s and canada and a possible threat to many more respondents are shoreline property owners on lakes without eurasian watermilfoil the estimated per property welfare loss of a lake invasion is 30 550 for one model and 23 614 for another both of which are in reasonable agreement with estimates obtained from a recent hedonic analysis of eurasian watermilfoil invasions in the study area 16 and from a companion contingent valuation survey of shoreline property owners on already invaded lakes

a comparison of alternative certainty calibration techniques in contingent valuation abstract a field test of two types of certainty calibration techniques in contingent valuation of public lands indicated that a 10 point certainty scale reduced wtp estimates by about half adjusting for uncertainty via a not sure option did not reduce wtp estimates but the variance increased there are several differences between these two ways of accounting for respondents uncertainty which may suggest why they provide different wtp value estimates and variances

what experimental protocol influence disparities between actual and hypothetical stated values preferences elicited in hypothetical settings have recently come underscrutiny causing estimates from the contingent valuation method to bechallenged due to perceived hypothetical bias given that the receivedliterature derives value estimates using heterogeneous experimentaltechniques understanding the effects of important design parameters onthe magnitude of hypothetical bias is invaluable in this paper we addressthis issue statistically by using a meta analysis to examine data from 29experimental studies our empirical findings suggest that on averagesubjects overstate their preferences by a factor of about 3 in hypotheticalsettings and that the degree of over revelation is influenced by thedistinction between willingness to pay and willingness to accept publicversus private goods and several elicitation methods

the net benefit of saving the asian elephant a policy and contingent valuation study reports results from a contingent valuation cv survey of willingness to pay wtp for the conservation of the asian elephant of a sample of urban residents living in three selected housing schemes in colombo the capital of sri lanka face to face surveys were conducted using an interview schedule is a non linear logit regression model is used to analyse the respondents responses for the payment principle questions and to identify the factors that influence their responses we investigate whether urban residents wtp for the conservation of elephants is sufficient to compensate farmers for the damage caused by elephants we find that the beneficiaries the urban residents could compensate losers the fanners in the areas affected by human elephant conflict hec and be better off than in the absence of elephants in sri lanka therefore there is a strong economic case for the conservation of the wild elephant population in sri lanka however we have insufficient data to determine the optimal level of this elephant population in the kaldor hicks sense nevertheless the current population of elephant in sri lanka is kaldor hicks preferable to having none c 2003 elsevier b v all rights reserved

flexible functional form estimation of willingness to pay using dichotomous choice data abstract this paper introduces fully flexible semi nonparametric methods for calculating willingness to pay wtp bounded between zero and the respondent s income for dichotomous choice contingent valuation a method to estimate median wtp using fully flexible functional forms is also presented finally the numerical illustration demonstrates the importance of considering jensen s inequality in calculating wtp with nonlinear models

actual averting expenditure versus stated willingness to pay the purpose of this study is to perform a complete comparison of actual averting expenditure and stated willingness to pay measures and to determine if the averting expenditure is a lower bound of the willingness to pay measured from contingent valuation experiment as suggested by literature in addition to the single value comparison bootstrap krinsky and robb jackknife and cameron are four simulation methods used to calculate confidence intervals for response function sample sizes of 100 200 and 1000 are simulated 100 and 200 times respectively a set of data with 540 households from a contingent policy referendum survey is employed for our purpose under a specific level of bod improvement a one to one single mean value comparison of the actual averting expenditure is greater than the mean willingness to pay from utility difference model the empirical results are consistent with the theoretical expectation for expenditure difference that averting expenditure is a lower bound of willingness to

evaluating the performance of benefit transfer an empirical inquiry abstract benefit transfers are used by public agencies needing information on costs and benefits of policy decisions although scientific debate regarding the validity of benefit transfer is ongoing this article develops a methodology to evaluate the performance of direct benefit transfer and benefit function transfer and applies the methodology to two pairs of similar non market amenities empirical results indicate that benefit function transfer is more robust than transfer of average site benefits our results suggest that the circumstances under which benefit function transfer provides valid policy relevant information may be limited and that errors from applying benefit transfer can be quite large even across seemingly similar amenities

improved estimation of willingness to pay in dichotomous choice contingent valuation studies this paper uses recently developed statistical techniques to achieve improved parameter estimates from models ofdichotomoiis choice contingent valuation data random effects associated with bid amounts presented to respondents are modelled alongside the variance of individual responses to give a nested model which more truly reflects the structure of the data being analyzed quasi likelihood methods for estimating parameters in such hierarchical models are discussed and a simulation method for assessing goodness of fit is demonstrated however estimated parameters may still be biased and hence a parametric bootstrap technique is presented and compared to a delta method approximation jel q26

property rights public enforcement and growth we study the link between public enforcement of property rights innovation investments and economic growth in an endogenous growth framework with an expanding set of product varieties we find that a government can assure positive equilibrium growth through public employment in the enforcement of property rights if the economic environment is sufficiently favorable to growth and or if public enforcement is sufficiently effective however in terms of welfare an equilibrium path without property rights protection and growth might be preferable in this case the enforcement of property rights involves too much reallocation of labor from production and research towards the public sector

prosperity without conflict abstract social conflict and slow growth are features of many developing economies this paper considers the role institutions of property rights and conflict management can play in both achieving prosperity and mitigating conflict in these economies we study how introducing conflict over economic distribution into an otherwise standard model of growth can shape optimal second best taxation policy when diversionary activities cannot be taxed in this context we find that the maximization of economic efficiency may call for a reduction in growth in order to mitigate the problem of diversion even though the economy s growth is inefficiently slow in the absence of taxation this is so when institutional quality is sufficiently poor but not otherwise the paper warns against the conventional justification of growth promoting policies on efficiency grounds independently of institutions

is there always too little research in endogenous growth with expanding product variety abstract it is generally believed that models of endogenous growth with expanding product variety typically yield a too low level of research we show here that this result is due to the implicit choice of a particular value for a crucial parameter once this parameter is set free one finds that too much research can occur as well

effective property rights conflict and growth abstract this paper shows how the interaction between conflict and growth can give rise to a nonmonotone relationship between property rights and social welfare this interaction is illustrated in a model of endogenous growth in which equilibrium diversion of resources is the cost of securing effective property rights a symmetric equilibrium allocation associated with more secure property rights and faster growth can be pareto dominated by one associated with poorer property rights and slower growth faster growth can exacerbate the problem of diversion whenever property rights are sufficiently poor these results call for caution before a society decides to pursue economic growth independently of the institutional structure of property rights furthermore if this structure is inappropriate piecemeal reform might not be in the interest of society and a substantial reform might be necessary if it is to be welfare improving

an independent sample test of yea saying and starting point bias in dichotomous choice contingent valuation abstract we developed several diagnostic tools to test the convergent validity of two common contingent valuation elicitation procedures data were collected from independent samples receiving dichotomous choice and payment card questions we compared actual with counter factual responses using deterministic and monte carlo methods and we found that wtp distributions and mean values varied by the value elicitation method we also developed a paired comparison test for procedure variance which indicated that yea saying and starting point bias influenced dichotomous choice responses

optimal protection of property rights in a general equilibrium model of growth we incorporate weak property rights into an otherwise standard general equilibrium model of growth and second best optimal policy in this setup the state plays two of its key roles it protects property rights and provides public services the government chooses policy the income tax rate as well as the allocation of collected tax revenues between law enforcement and public services to maximize the growth rate of the economy the focus of our analysis is on how weak property rights generate multiple decentralized competitive equilibria the different properties of these equilibria and the implications of second best optimal policies

tough and easy choices testing the influence of utility difference on stated certainty in choice in choice experiments respondents in stated preference studies may be uncertain about their preferences for the good presented to them inspired by wang j environ econ manag 32 219 232 1997 we hypothesize that respondents stated certainty in choice increases with the utility difference between the alternative chosen and the best alternative to that we test this hypothesis using data from two independent choice experiments both focusing on nature values in modelling respondents self reported certainty in choice we find evidence that the stated level of certainty increases significantly as utility difference in choice sets increases in addition stated certainty increases with income furthermore there is some evidence that male respondents are inherently more certain in their choices than females and a learning effect may increase stated certainty we find evidence of this in the first study where the good is described in rather broad and generic terms but not in the second study where a more specific description of the good is used

dichotomous choice contingent valuation with dont know responses and misreporting a new approach is presented that simultaneously deals with misreporting and don t know dk responses within a dichotomous choice contingent valuation framework utilising a modification of the standard bayesian probit framework a gibbs with metropolis hastings algorithm is used to estimate the posterior densities for the parameters of interest several model specifications are applied to two contingent valuation datasets one on wolf management plans and one on the us fee demonstration program we find that dks are more likely to be from people who would be predicted to have positive utility for the bid therefore a dk is more likely to be a yes than a no we also find evidence of misreporting primarily in favour of the no option the inclusion of dk responses has an unpredictable impact on willingness to pay estimates since it impacts differently on the results for the two datasets we examine copyright c 2009 john wiley sons ltd

discrete choice under preference uncertainty an improved structural model for contingent valuation abstract this paper is concerned with discrete choice contingent value estimation in the presence of response errors we attempt to extend the theoretical frameworks developed by hanemann 1984 amer j agric econom 66 332 341 and cameron 1988 j environ econom management 15 355 379 by introducing preference uncertainty with individual respondents we assume that respondents have incomplete knowledge about their true valuation of a nonmarket resource and thus may give wrong yes no answers on whether or not to pay a given bid amount for the resource a post decisional confidence measure for each observed yes no answer is elicited for characterizing the degree of preference uncertainty with the help of this confidence measure we develop an improved structural model for deriving value estimates data from a forest environment valuation survey are used for the empirical estimations

stated versus revealed knowledge determinants of offsetting co2 emissions from fuel consumption in vehicle use abstract this paper examines the role of prior knowledge in offsetting co2 emissions from fuel consumption in vehicle use the main result of our econometric analysis on the basis of unique representative data from drivers license holders in the usa and germany refers to the strong discrepancy between the stated and revealed knowledge of co2 offsetting the revealed knowledge measured by the correct estimation of the costs for this offsetting practice has a positive impact on the stated purchase of corresponding offsetting credits in both countries in contrast the effect of the stated knowledge of offsetting is not robust and in some cases even negative surprisingly it cannot even be confirmed that drivers license holders who claim that they are more than sufficiently informed estimate these costs more accurately

is political rivalry an incentive to vote according to the theory of the rational voter s behavior riker and ordeshook 1968 the decision to vote depends among other things on the expected effectiveness of his vote to bring to power his preferred candidate or party though this hypothesis is valid in the case of a two party political system in the case of a multi party system one has to take into consideration the influence of the competition2 between parties upon the vote s efficiency and on the distribution of the votes among parties3 in a multi party system quite often no one party is in a position to win an overal majority and the result is a governmental coalition therefore the voter is in more doubt about the effectiveness of his vote for a given number of parties the closer the outcome of the election the more likely people would be to vote see tullock 1972 110 an increase in the number of parties might be considered as contributing to a better representation of the electorate s preferences and therefore as an incentive to vote on the other hand when parties become too numerous there could be a weakening of power among them and that in turn would cancel out the incentive to vote therefore an optimal degree of competition encouraging electoral participation as shown in figure 1 must exist4 this paper will concentrate on the assessment of the explanatory power of the competition among parties upon the rate of electoral participation it should however not be overlooked that in practice there are many factors of an institutional as well as of a psychological nature which prevent such an ideal balance being attained factors affecting the voter s behavior such as compulsory participation tend to reduce considerably the margin between the expected benefit from voting and the costs the development of efficient lobbies considered by the voter to be more likely to support his preferences in parliament tend to reduce the

inference and optimal design for a welfare measure in dichotomous choice contingent valuation this paper considers the use of contingent valuation to estimate non market benefits from separately valued nested goods survey respondents were asked referendum wtp questions regarding either a scheme to protect the whole area of a wetland or a

bias in discrete response contingent valuation abstract the empirical literature on discrete response contingent valuation has found that seemingly innocuous changes in the statistical models estimated result in significantly different point estimates of willingness to pay this paper hypothesizes and tests several potential explanations for these results first it investigates and compares the biases inherent in single bounded and double bounded maximum likelihood estimation procedures and examines how they react to various bid designs and sample sizes then it examines the presence and identification of outliers in binary choice data and how these outliers influence estimation finally it presents an alternative approach to addressing the issue of outliers which explicitly acknowledges the possibility of upwardly biased response probabilities

a comparison of approaches to calculating confidence intervals for benefit measures from dichotomous choice contingent valuation surveys this paper compares the performance of four approaches to calculating confidence intervals around dichotomous choice contingent valuation method dc cvm benefit estimates the performance of the approaches is compared using monte carlo simulation techniques for the two most common specifications for the welfare estimate the results indicate that all four methods tended to perform well on average but the methods differed in the frequency with which they performed well the results indicate the best choice depends on the sample size on the distribution of the welfare estimate and on the choice of functional form for the welfare estimate

construct validity of dichotomous and polychotomous choice contingent valuation questions in this note we conduct construct validity tests for dichotomous choice dc and polychotomous choice pc contingent valuation questions contrary to previous results we find that dc and pc estimates of willingness to pay are theoretically valid convergent valid and similar in terms of statistical precision similar to previous results pc respondents are less sensitive to information than dc respondents we conclude that dc and pc valuation questions are construct valid for this study sequential pc valuation questions could be used in studies where obtaining information about the certainty or intensity of respondent preferences would be useful

voter turnout and the principle of one person one vote empirical evidence from the constituency freeze in india this article uses panel data from national and state elections in india during the period 1977 2007 to examine the effect of inequality in constituency population size on voter turnout during this period constituency boundaries in india remained fixed as a result differences in population size between constituencies increased thus changing the value of a single vote using this large variation in population size and informative data this article carefully distinguishes the effect of population size from other factors we find that an increase of one million electorates decreases voter turnout by 12 27 in addition we find that the share of votes gained by national political parties is greater in small population constituencies this suggests that political parties direct their efforts in electoral campaigns preferentially to less populous constituencies as a result voters in small constituencies are more likely to participate in elections

respondent uncertainty in a contingent market for carbon offsets abstract the main objective of this paper is to provide additional empirical evidence of what explains respondent uncertainty in contingent valuation cv and how this in turn affects stated willingness to pay wtp air travelers asked to pay a carbon travel tax to offset carbon emissions from flying were asked how likely it is that they will actually pay if the tax is voluntary when changing the market compliance imperative from a mandatory carbon tax to a voluntary contribution a third of all air travelers consider it unlikely they will actually pay their stated wtp amount an ordered probit estimation approach is applied to identify the sources of respondent uncertainty besides the bid price respondent sense of responsibility and belief in the effectiveness of the voluntary carbon market are among the main reasons for the experienced uncertainty
