estimation using contingent valuation data from a dichotomous choice with follow up questionnaire a comment abstract cameron and quiggin j environ econom management27 218 234 1994 provide evidence against the use of the standard interval data model and in favor of the more general bivariate probit model an apparent miscalculation in the estimation process overstates the poor performance of the interval data model for the application reported by cameron and quiggin when the miscalculation is corrected the data reported by cameron and quiggin provide results consistent with alberini s j environ econom mangement29 169 180 1995 finding that interval data models provide robust estimates of mean willingness to pay from dichotomous choice with follow up contingent valuation questions

the motivation and bias of bureaucrats many individuals are motivated to exert effort because they care about their jobs rather than because there are monetary consequences to their actions the intrinsic motivation of bureaucrats is the focus of this paper and three primary results are shown first bureaucrats should be biased second sometimes this bias takes the form of advocating for their clients more than would their principal while in other cases they are more hostile to their interests for a range of bureaucracies those who are biased against clients lead to more efficient outcomes third self selection need not produce the desired bias instead selection to bureaucracies is likely to be bifurcated in the sense that it becomes composed of those who are most preferred by the principal and those who are least preferred

statistical efficiency of double bounded dichotomous choice contingent valuation the statistical efficiency of conventional dichotomous choice contingent valuation surveys can be improved by asking each respondent a second dichotomous choice question which depends on the response to the first question if the first response is yes the second bid is some amount greater than the first bid while if the first response is no the second bid is some amount smaller this double bounded approach is shown to be asymptotically more efficient than the conventional singlebounded approach using data from a survey of californians regarding their willingness to pay for wetlands in the san joaquin valley we show that in a finite sample the gain in efficiency can be very substantial

conformity and the demand for environmental goods the existing literature on eco labeling and green consumerism has been framed within a classical market context where price and quality are the drivers of consumer choice however it seems possible that consumers are also concerned about the choices made by other consumers in fact it is unclear that people s consumption decisions are made independently of social context for instance under the desire to conform to certain social norms or in the presence of status concerns some individuals may be willing to pay a higher price premium for green products the more widespread green consumerism is in society we test this hypothesis using a choice experiment where the respondents were asked to choose among coffee products varying with respect to their share of ecological beans share of fair trade beans and price three treatments were used differing only in the information given about the choices made by other consumers we find different responses to the treatments across individuals and we can only confirm our hypothesis of conformity for women although men appear to have stronger preferences for ecological coffee than women have

sincerity in corporate philanthropy stakeholder perceptions and firm value this study extends the literature on symbolic management by incorporating the role of stakeholder perceptions into the context of corporate philanthropy in particular we differentiate between the quantitative generous giving and qualitative innovative giving aspects of giving we argue that although stakeholders may perceive both types of giving as being substantive rather than symbolic innovative giving is likely to be perceived as more substantive than generous giving is and thus has a greater impact on firm value furthermore stakeholder perceptions of corporate philanthropy as being more symbolic or substantive are influenced by firm characteristics the type of products or services that a firm provides and the life cycle stage that the firm is in which provide stakeholders with a context to better assess the nature of a firm s philanthropic actions and the substantiveness of its giving we find support for our predictions using a sample covering u s firms philanthropic activities over a 19 year period

estimation using contingent valuation data from a dichotomous choice with follow up questionnaire reply abstract our original article proposed that the two yes no willingness to pay wtp responses produced by this survey format should be viewed as a pair of jointly distributed correlated discrete random variables the comparison model the conventional approach to estimation using these types of data contained a programming error correction alters the results from the comparison model but our original claim that estimation by conventional methods can produce misleading inferences if ours is the appropriate specification still stands this is especially true if negative wtp is precluded when e wtp is calculated

consumer attitudes toward low stake risk in food markets consistency of quality is viewed as important for producers of consumer goods however there is no literature testing the importance of quality consistency on consumers willingness to pay for consumer goods we use an experimental auction market to investigate how inconsistency in tenderness affects consumers willingness to pay for beef we find that most consumers are risk averse with respect to sensory quality both the average tenderness and the variance of tenderness affected the consumers willingness to pay for beef reducing the uncertainty of the sensory quality by categorizing the beef into three tenderness classes increased the total value of the beef by 8

do reminders of substitutes and budget constraints influence contingent valuation estimates a test is performed of the recommendation by the noaa panel on contingent valuation that respondents be reminded about other substitute resources and their budget constraint prior to answering the willingness to pay wtp question the context for this experiment is a cvm study of the benefits from reducing fire hazards to old growth forests in oregon the test was performed using two mail surveys that were otherwise identical except for the inclusion of reminder statements prior to the wtp question the dichotomous choice logit equations were not statistically different between versions and the mean wtp results were identical

hypothetical bias cheap talk and stated willingness to pay for health care subjects with rheumatoid arthritis ra enrolled in an online panel were asked to evaluate pairs of treatment alternatives with different attributes half of the sample saw a cheap talk text preference parameters were estimated using random parameters logit models to account for unobserved taste heterogeneity the models also were estimated in willingness to pay wtp space instead of conventional utility space cheap talk not only affected the coefficient on the cost attribute but also preferences for other attributes wtp estimates were generally lower in cheap talk sample except for the most important attribute and a 2 level attribute subjects who were presented with cheap talk discriminated between the adjoning attribute levels better than the subjects in the control sample

a new approach to valuing a life abstract because the issue of how to put a monetary value on a life will always be controversial this paper presents an alternative approach that can in certain circumstances avoid the use of monetary values the alternative approach uses time as the numeraire this numeraire can handle both the ex ante and ex post approaches to valuing a life after showing how a simple two period consumer choice problem can be translated into terms of time the paper considers an application that involves reformulating the data used to evaluate the 55 mph speed limit decision in the united states

interval estimates of non market resource values from referendum contingent valuation surveys contingent valuation methods cvm have attracted considerable attention in recent years as researchers have begun to resort to survey methods to elicit individual values for non market goods such as environmental resources or public goods cummings brookshire and schulze 1986 and mitchell and carson 1989 offer comprehensive assessments of these methods cvm survey questions come in a variety of forms one format which has proven to be popular is called the discrete choice or take it or leave it referendum or closedended question originally implemented in the literature by bishop and heberlein 1979 since respondents find it very difficult to identify precisely their true point value of access to some resource or public good open ended valuation questions can be unreliable or can discourage response in contrast most people are familiar with being confronted by a posted price for a good and with deciding whether or not they would buy at that price this is the strategy behind discrete choice cvm questions a different hypothetical price is offered to each respondent and by their yes no response to the question of whether they would be willing to pay this price the researcher gains information about their true underlying point value one persistent difficulty with the econometric techniques that are currently used most widely to analyze referendum contingent valuation data is the absence of confidence intervals for the ultimate value estimates early empirical applications approximate mean valuations using a truncated mean based on a logit model with the upper limit being the highest bid value in the sample unfortunately the variance of this estimated mean cannot easily be recovered from the numerical integration procedure commonly used to calculate the

demand for beef from cattle administered growth hormones or fed genetically modified corn a comparison of consumers in france germany the united kingdom and the united states we compare consumer valuations of beef ribeye steaks from cattle produced without growth hormones or genetically modified corn in france germany the united kingdom and the united states results suggest that french consumers place a higher value on beef from cattle that have not been administered added growth hormones than u s consumers however valuations of non hormone treated beef are statistically indistinguishable across germany the united kingdom and the united states results also suggest that european consumers place a much higher value on beef from cattle that have not been fed genetically modified corn than u s consumers copyright 2003 oxford university press

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

an introduction to field experiments in economics this special issue highlights an empirical approach that has increasingly grown in prominence in the last decade field experiments while field experiments can be used quite generally in economics to test theories predictions to measure key parameters and to provide insights into the generalizability of empirical results this special issue focuses on using field experiments to explore questions within the economics of charity the issue contains six distinct field experimental studies that investigate various aspects associated with the economics of charitable giving the issue also includes a fitting tribute to one of the earliest experimenters to depart from traditional lab methods peter bohm who curiously has not received deep credit or broad acclaim hopefully this issue will begin to rectify this oversight this abstract was borrowed from another version of this item

public service motivation as an argument for government provision a public service motivation psm inclines employees to provide effort out of concern for the impact of that effort on a valued social service though deemed to be important in the literature on public administration this motivation has not been formally considered by economists when a psm exists this paper establishes conditions under which government bureaucracy can better obtain psm motivated effort from employees than a standard profit maximizing firm the model also provides an efficiency rationale for low powered incentives in both bureaucracies and other organizations producing social services 2000 elsevier science s a all rights reserved

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 theoretical structure of producer willingness to pay estimates this article analyzes the theoretical underpinnings of producer willingness to pay wtp for new inputs in addition to conceptualizing the producer wtp function we derive its comparative statics and show how these properties can be used to estimate quantities demanded or supplied and price elasticities we also discuss implications of the comparative statics

whither the nonprofit wage differential estimates from the 1990 census this article provides new estimates of the nonprofit for profit wage differential in the u s economy using observations on 4 1 million private sector employees from the 1990 census i find either zero or slightly positive economy wide wage differences between nonprofit and for profit employees in a standard earnings equation format significant wage differentials are found at the disaggregated occupation and industry level and provide a basis for testing hypotheses explaining nonprofit for profit wage differences

are korean consumers willing to pay a tax for a mandatory bse testing programme the outbreaks of mad cow disease bse have significantly increased the demand for food safety programs in the korean beef market two issues that are getting much attention are about whether korea should implement mandatory testing of slaughtered domestic cattle for bse and whether consumers are willing to pay a tax for the programme no study however has examined consumers willingness to pay wtp a tax for a bse testing programme we conducted a contingent valuation cv study using a double bounded dichotomous choice approach to estimate korean consumers valuation for a mandatory bse testing programme on slaughtered domestic cattle that are 21 months or older our results show that the sample population adjusted mean estimate of wtp a tax per year is 4482 krw us 4 01 per household this suggests that korean consumers have a strong preference for a mandatory testing of domestic cattle for bse this study also found that korean consumers wtp for the programme is greater than estimated implementa

social responsibility messages and worker wage requirements field experimental evidence from online labor marketplaces this paper examines the effects of employer social responsibility on the wages workers demand through randomized field experiments in two online labor marketplaces workers were recruited for short term jobs and i manipulated whether or not they received information about the employer s social responsibility i then observed the payment workers were willing to accept for the job in the first experiment information about the employer s social responsibility marginally reduced prospective workers wage requirements on average and had a significant effect on the highest performers who were willing to give up the wage differential they would otherwise demand in the second prospective workers submitted 44 lower wage bids for the same job after learning about the employer s social responsibility this paper provides causal empirical evidence of a revealed preference for social responsibility in the workplace and of a greater preference among the highest performers more broadly it provides evidence that

industry or academia basic or applied career choices and earnings trajectories of scientists we extend life cycle models of human capital investments by incorporating matching theory to examine the sorting pattern of heterogeneous scientists into different career trajectories we link differences in physical capital investments and complementarities between basic and applied scientists across industry and academic settings to individual differences in scientist ability and preferences to predict an equilibrium matching of scientists to careers and to their earnings evolution our empirical analysis using the national science foundation s scientists and engineers statistical data system database is consistent with theoretical predictions of i sorting by ability into basic versus applied science among academic scientists but not among industry scientists and ii sorting by higher taste for nonmonetary returns into academia over industry the evolution of an earnings profile is consistent with these sorting patterns the earnings trajectories of basic and applied scientists are distinct from each other in academia but are similar in industry this paper was accepted by lee fleming entrepreneurship and innovation

gender specific starting point bias in choice experiments evidence from an empirical study abstract in this paper we test whether preferences and willingness to pay estimates obtained in a choice experiment study are susceptible to starting point bias as is often the case in dichotomous choice contingent valuation studies on the basis of a multinomial probit model we find that preferences are indeed susceptible to starting point bias in a split sample design our results suggest that varying the price levels displayed in a so called instructional choice set presented prior to the actual preference eliciting choice sets significantly impacts respondents preferences and willingness to pay for protecting danish nature areas from new motorway development in particular our results show that the bias is gender specific only female respondents are significantly affected results further reveal that the impact of the starting point bias decays as respondents evaluate more and more choice sets this supports the discovered preference hypothesis and on the basis of this we suggest a number of ways to potentially mitigate the starting point bias

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

on mandatory labeling of animal welfare attributes this paper assesses us resident support for mandatory labeling of animal welfare information on pork and egg products and outlines policy considerations for assessment prior to implementing any mandatory labeling policies regarding animal welfare practices results suggest consumers support mandatory labeling indicating use of gestation crates stalls and laying hen cages estimates suggest consumers would be willing to pay about 20 higher pork and egg prices to obtain this production practice information demographic and latent perception drivers of this support are highlighted multiple issues that warrant consideration prior to imposing mandatory labeling are discussed revealing lines of corresponding future research

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

show me the money the value of college graduate attributes as expressed by employers and perceived by students employers of agricultural undergraduates are presented with hypothetical job candidates with different attributes and salaries and are asked which candidate if any they would hire the employer choices are then used to estimate the additional salary they will pay for undergraduates with certain attributes students are administered similar surveys where they indicate which hypothetical candidate they think will be hired which can be used to estimate students perceived salary increase associated with each attribute employers stated values are then compared to students perceived values to identify any misperceptions regarding the monetary return of select attributes

the corporate social performance financial performance link strategic managers are consistently faced with the decision of how to allocate scarce corporate resources in an environment that is placing more and more pressures on them recent scholarship in strategic management suggests that many of these pressures come directly from sources associated with social issues in management rather than traditional arenas of strategic management using a greatly improved source of data on corporate social performance this paper reports the results of a rigorous study of the empirical linkages between financial and social performance corporate social performance csp is found to be positively associated with prior financial performance supporting the theory that slack resource availability and csp are positively related csp is also found to be positively associated with future financial performance supporting the theory that good management and csp are positively related 1997 by john wiley sons ltd

comparing open ended choice experiments and experimental auctions an application to golden rice we use two experimental valuation methods to estimate consumer demand for genetically modified golden rice the first is an open ended choice experiment oece where participants name the quantities of golden rice and conventional rice demanded at each of several price combinations one of which will be randomly chosen as binding this allows us to estimate market demand by aggregating demand across participants this estimate of market demand also allows us to estimate own price elasticity and consumer surplus for golden rice comparing willingness to pay wtp estimates from the oece with those from a uniform price auction we find that oece wtp estimates exhibit less affiliation across rounds and the effects of positive and negative information under the oece are more consistent with prior expectations and existing studies we also find that while auction wtp estimates more than double across five rounds oece wtp estimates are stable across rounds and are always roughly equal to those from the final auction round

are we willing to pay enough to back the bid valuing the intangible impacts of london s bid to host the 2012 summer olympic games using a contingent valuation survey this paper provides the first empirical test of the proposition that intangible impacts might justify hosting major sporting events on cost benefit grounds respondents drawn from london manchester and glasgow were asked for their willingness to pay wtp to host the 2012 olympic games in london on the basis of the intangible impacts that this event might provide annual mean wtp is 22 12 and 11 per year for 10 years in these 3 uk cities respectively an illustrative total uk wtp for intangible impacts is in the region of 2 billion statistical analysis of wtp determinants reveals a range of plausible explanatory factors such as respondents degree of support for the bid

risk perceptions risk preference and acceptance of risky food consumers risk preferences are often overlooked in studies of consumer demand for risky food we find that risk preferences elicited through context less lottery choices are significantly related to consumers stated preferences for genetically modified gm food these results suggest risk preferences elicited in the laboratory are not artificial in the sense that they appear to be related to the same risk preferences that govern other individual decisions such as food choice consistent with theoretical expectations risk perceptions and risk preferences were found to be significant determinants of acceptance of gm food which has important implications for explaining consumer behavior

releasing the trap a method to reduce inattention bias in survey data with application to u s beer taxes this study uses discrete choice experiments to explore the efficacy of prompts targeted at reducing inattention bias upon receiving feedback inattentive respondents are given the opportunity to reanswer a so called trap question that checks for attentiveness we find that individuals who miss trap questions and do not correctly revise their responses have significantly different choice patterns as compared to individuals who correctly answer the trap question adjusting for these inattentive responses has a substantive impact on policy impacts results based on attentive participant responses indicate that a minimum beer price would have to be substantial to substantially reduce beer demand jel c83 q18 q51

charity as a substitute for reputation evidence from an online marketplace consumers respond positively to products tied to charity particularly from sellers that are relatively new and hence have limited alternative means for assuring quality we establish this result using data from a diverse group of ebay sellers who experiment with charity by varying the presence of a donation in a set of otherwise matched product listings most of charity s benefits accrue to sellers without extensive ebay histories consistent with charity serving as a quality signal we find fewer customer complaints among charity intensive sellers

consumer benefits of labels and bans on gm foods choice experiments with swedish consumers the european union has been relatively cautious about using biotechnology in food production a label regime combined with the right of individual member states to ban introduction of new genetically modified gm strains means that gm food products in effect are banned in many countries we show how it is possible to empirically test whether a ban can be motivated by reference to potential negative externalities this is followed up by results from a choice experiment we cannot reject the hypothesis of equal wtp for a ban and a labeling scheme

signaling and screening of workers motivation abstract this paper develops a model in which workers are heterogeneous in their intrinsic motivation to work at a firm we characterise optimal incentive schemes and examine how the firm can attract and select highly motivated workers to fill a vacancy when workers motivation is private information while posting a higher wage increases the probability of filling the vacancy it decreases the expected average quality of job applicants because less motivated workers are induced to apply the optimal wage scheme entails a trade off between the probability of filling the vacancy the rents left to the worker and the expected worker s motivation

on consumers willingness to purchase nutritionally enhanced genetically modified food this study assesses consumers willingness to purchase genetically modified gm food products with two different types of benefits an input i e reduced pesticides and an output trait benefit i e nutritionally enhanced data were collected using a telephone survey of an italian households sample discrete choice approach is used to elicit the purchase intentions of the respondents four separate probit models are estimated to examine the effect of various factors on choices results suggest that majority of italians are not willing to buy gm food products even if they are nutritionally enhanced however more consumers are willing to buy a nutritionally enhanced plant based gm product than a traditional plant based gm with input trait benefit willingness to buy for a nutritionally enhanced animal based gm product and for a traditional animal based gm product with input trait benefit are similar consumers unwilling to buy gm food would not buy it even if it is nutritionally enhanced and has lo

corporate philanthropy and productivity evidence from an online real effort experiment contributing to a social cause can be an important driver for workers in the public and nonprofit sectors as well as in firms that engage in corporate philanthropy or other corporate social responsibility policies this paper compares the effectiveness of a social incentive that takes the form of a donation received by a charity of the subject s choice to a financial incentive we find that social incentives lead to a 13 rise in productivity regardless of their form lump sum or related to performance or strength the response is strong for subjects with low initial productivity 30 whereas high productivity subjects do not respond when subjects can choose the mix of incentives half sacrifice some of their private compensation to increase social compensation with women more likely to do so than men furthermore offering subjects some discretion in choosing their own payment schemes leads to a substantial improvement in performance comparing social incentives to equally costly increases in private compensation for low productivity subjects reveals that the former are less effective in increasing productivity but the difference is small and not statistically significant data as supplemental material are available at http dx doi org 10 1287 mnsc 2014 1985 this paper was accepted by uri gneezy behavioral economics

economics and identity this paper considers how identity a person s sense of self affects economic outcomes we incorporate the psychology and sociology of identity into an economic model of behavior in the utility function we propose identity is associated with different social categories and how people in these categories should behave we then construct a simple game theoretic model showing how identity can affect individual interactions the paper adapts these models to gender discrimination in the workplace the economics of poverty and social exclusion and the household division of labor in each case the inclusion of identity substantively changes conclusions of previous economic analysis

the effect of knowledge on the disparity between hypothetical and real willingness to pay the use of a contingent valuation cv method is controversial among economists because it is based on hypothetical rather than real economic choices this paper reports the results of an experiment designed to elicit the real and the hypothetical willingness to pay wtp for a private good the effect of different settings of knowledge direct and indirect of the good on subjects valuation behaviour are investigated the findings show that i a direct knowledge of the good reduces the observed disparity between hypothetical and real wtp and that ii different settings of knowledge generate different perceptions of the characteristics of the good

effects of cheap talk on consumer willingness to pay for golden rice a large body of literature suggests willingness to pay is overstated in hypothetical valuation questions as compared to when actual payment is required recently cheap talk has been proposed to eliminate the potential bias in hypothetical valuation questions cheap talk refers to process of explaining hypothetical bias to individuals prior to asking a valuation question this study explores the effect of cheap talk in a mass mail survey using a conventional value elicitation technique results indicate that cheap talk was effective at reducing willingness to pay for most survey participants however consistent with previous research cheap talk did not reduce willingness to pay for knowledgeable consumers

breaking monotony with meaning motivation in crowdsourcing markets abstract we conduct the first natural field experiment to explore the relationship between the meaningfulness of a task and worker effort we employed about 2500 workers from amazon s mechanical turk mturk an online labor market to label medical images although given an identical task we experimentally manipulated how the task was framed subjects in the meaningful treatment were told that they were labeling tumor cells in order to assist medical researchers subjects in the zero context condition the control group were not told the purpose of the task and in stark contrast subjects in the shredded treatment were not given context and were additionally told that their work would be discarded we found that when a task was framed more meaningfully workers were more likely to participate we also found that the meaningful treatment increased the quantity of output with an insignificant change in quality while the shredded treatment decreased the quality of output with no change in quantity we believe these results will generalize to other short term labor markets our study also discusses mturk as an exciting platform for running natural field experiments in economics

competition and incentives with motivated agents a unifying theme in the literature on organizations such as public bureaucracies and private nonprofits is the importance of mission as opposed to profit as an organizational goal such mission oriented organizations are frequently staffed by motivated agents who subscribe to the mission this paper studies incentives in such contexts and emphasizes the role of matching the mission preferences of principals and agents in increasing organizational efficiency matching economizes on the need for high powered incentives it can also however entrench bureaucratic conservatism and resistance to innovations the framework developed in this paper is applied to school competition incentives in the public sector and in private nonprofits and the interdependence of incentives and productivity between the private for profit sector and the mission oriented sector through occupational choice jel d23 d73 h41 l31 the late twentieth century witnessed a historic high in the march of market capitalism with unbridled optimism in the role of the profit motive in promoting welfare in the production of private goods moreover this generated a broad consensus on the optimal organization of private good production through privately owned competitive firms when it comes to the provision of collective goods no such consensus has emerged debates about the relative merits of public and private provision still dominate this paper suggests a contracting approach to the provision of collective goods it focuses on two key issues how to structure incentives and the role of competition between providers at its heart is the idea that organizations that provide collective goods cohere around a mission 2 thus production of collective goods can be viewed as mission oriented

affect or information labeling policy and consumer valuation of rbst free and organic characteristics of milk abstract using a labeling policy framework we answer the question of whether attitude has an impact on consumers valuation of rbst free and organic characteristics of milk we utilize 2 years of consumer survey data and a hedonic model to estimate marginal effects of attitude on consumer valuation of rbst free and organic milk findings indicate that in 2001 milk value was impacted by attitude regardless of whether attitude was measured using an opinion based or behavioral construct in 2004 the contribution of attitude to value was insignificant implications for labeling policy are discussed

crowding out in the labor market a prosocial setting is necessary recent studies mostly from prosocial settings suggest that monetary rewards may crowd out effort exertion by economic agents we design a field experiment with data entry workers to investigate the extent of such crowding out effects in a labor market using simple variations in the job description of a task we induce a natural work setting under the work frame and emphasize social preference under the social frame we find that crowding out of labor participation critically depends on framing whereas small monetary rewards reduce the participation rate under the social frame the participation rate is nondecreasing in the wage rate under the work frame moreover among the workers who participate in the task those who receive a positive wage perform a considerably higher amount of work than those who are paid zero wage under either frame thus there is weak evidence of crowding out only when the task is explicitly given a prosocial flavor and not under a regular work setting furthermore emphasizing social preference in the labor market in such a way reduces the overall labor supply and seems to have an adverse effect on the quality of work data as supplemental material are available at http dx doi org 10 1287 mnsc 2013 1807 this paper was accepted by john list behavioral economics

efficient estimation methods for closed ended contingent valuation surveys closed ended contingent valuation surveys can be very useful in the evaluation of nonmarket resources respondents merely state whether they would accept or reject a hypothetical threshold amount either as payment for giving up access to the resource or as a fee for its use the authors develop a maximum likelihood procedure which exploits the variation in the threshold values to allow direct and separate point estimates of regression like slope coefficients and error standard deviations without truncation bias their illustration uses data from a survey of recreational fisherman to examine factors which influence individuals willingness to pay copyright 1987 by mit press

preference learning in consecutive experimental auctions this paper explores the origins of the strikingly high price premia paid for new food products in lab valuation exercises our experimental design distinguishes between two explanations of this phenomenon novelty of the experimental experience versus the novelty of the good i e preference learning bids reflect a person s desire to learn how an unfamiliar good fits into their preference set subjects bid in four consecutive experimental auctions for three goods that vary in familiarity candy bars mangos and irradiated meat our results suggest that preference learning is the main source of the high premia and that novelty of the experimental experience does not in itself artificially inflate valuations copyright 2000 oxford university press

using ex ante approaches to obtain credible signals for value in contingent markets evidence from the field while contingent valuation remains the only option available for measurement of total economic value of nonmarketed goods the method has been criticized due to its hypothetical nature we analyze field experimental data to evaluate two ex ante approaches to attenuating hypothetical bias directly comparing value statements across four distinct referenda hypothetical cheap talk consequential and real our empirical evidence suggests two major findings hypothetical responses are significantly different from real responses and responses in the consequential and cheap talk treatments are statistically indistinguishable from real responses we review the potential for each method to produce reliable results in the field

man s search for meaning the case of legos we investigate how perceived meaning influences labor supply in a laboratory setting we manipulate the perceived meaning of simple repetitive tasks and find a strong influence on subjects labor supply despite the fact that the wage and the task are identical across the conditions in each experiment subjects in the less meaningful conditions exhibit reservation wages that are consistently much higher than the subjects in the more meaningful conditions the result replicates across different types of tasks moreover in the more meaningful conditions subjects productivity influences labor supply more strongly

evaluating the validity of the dichotomous choice question format in contingent valuation hypothetical and actual cash willingness to pay wtp for an art print were elicited with dichotomous choice and open ended question formats comparing hypothetical and actual dichotomous choice responses using both a likelihood ratio test and the method of convolutions suggests we reject equality at the 0 05 but not the 0 01 level hypothetical wtp was roughly two times actual wtp with the dichotomous choice format there were no significant differences between the open ended and dichotomous choice question formats when both were used to estimate hypothetical wtp or both used to estimate actual wtp

hypothetical actual bid calibration of a multigood auction abstract evidence suggests the calibration of hypothetical and actual behavior is good specific we examine whether clustering commodities into mutual categories can reduce the burden while we reject a common calibration across sets of commodities a sport specific calibration function cannot be rejected

referendum models and economic values theoretical intuitive and practical bounds on willingness to pay innovations in the estimation of referendum type contingent valuation models have led to willingness to pay wtp measures inconsistent with consumer preferences and unbounded from above or below we propose a set of criteria which guarantee a bounded measure of wtp the criteria reject the traditional random utility model with unrestricted error terms in favor of the random wtp model with bounds on wtp once wtp is bounded by zero and income the form of the distribution is less consequential a new model for wtp is developed based on the beta distribution and is compared to previously estimated models

dynamic hypothetical bias in discrete choice experiments evidence from measuring the impact of corporate social responsibility on consumers demand abstract this paper is aimed at studying the dynamics of consumers preferences for corporate social responsibility the data come from both a discrete choice experiment dce and a field experiment conducted in a real market setting the results show that in a static setting first month predictions of a standard dce study and real market shares are statistically similar for the various profiles of corporate social responsibility however as time evolves real market shares present some dynamic patterns that are not mirrored by the standard dce predictions the overall conclusion is that differences between real market behavior and dce data can be attributed to the lack of learning experience or adaptation in dce surveys rather than to the hypothetical nature of the experiments

reducing transatlantic barriers on u s eu agri food trade what are the possible gains in recent years the eu and the u s have engaged in discussions to lower trade and investment barriers and strengthen transatlantic integration for food and agricultural trade non tariff measures ntms such as sanitary and phytosanitary measures sps stand out as significant barriers this study combines sector level econometric modeling with an agriculture focused computable generable equilibrium cge model to simulate various transatlantic liberalization scenarios on u s eu agri food trade the simulations quantify the effect from tariff removal and addressing ntms the magnitude of the gains depend upon the level of tariff liberalization the depth of integration and possible consumer demand changes

are hypothetical referenda incentive compatible a comment in a recent article in this journal cummings al 1997 offer experimental evidence rejecting the hypothesis that a hypothetical referendum is an incentive compatible mechanism for obtaining the social value of or willingness to pay for changes in the allocation of environmental goods and services while cautions in offering a blanket rejection of hypothetical referenda as a means of measuring economic values on the basis of their findings the authors do suggest that at least in experimental settings respondents appear to behave differently when real money is changing hands wheather hypothetical situations adequately mimic real market situations has been debated in the contigent valuation literature since its inception see cummings brookshire and schulze 1986 cummings et al s finding of incentive incompatibility appears to offer strong evidence for the critics of hypothetical referenda

producer decision making under uncertainty role of past experiences and question framing limited research examines the role of reference points or how uncertain outcomes are processed in producer decisions this study employs a survey containing a split sample choice experiment varying how uncertain outcomes are portrayed and assesses multiple candidate reference points results suggest that u s cattle producers use the best outcome experienced as reference points in their decisions and the method by which uncertain outcomes are presented impacts loss aversion marginal willingness to pay and market participation estimates this illustrates how research employing split samples multiple reference points and alternative methods of portraying uncertain outcomes may better identify producer decision making

the cross price effect on willingness to pay estimates in open ended contingent valuation abstract previous literature has shown that potential buyers use a reference price or product to form their opinion about the value of a new product therefore the pricing decision is an interactive process we investigate the two generalizations of the cross price effect the neighborhood price effect and the asymmetric price effect on consumer willingness to pay wtp for multiple similar products in an open ended contingent valuation context results show that the cross price effect on wtp is prominent with the neighborhood price effect holding in contingent valuation no conclusions are reached about the asymmetric price effect

the dispersion and development of consumer preferences for genetically modified food a meta analysis this paper presents a meta analysis of 51 primary studies reporting a total of 114 genetically modified food valuation estimates results indicate that elicitation methods and formats used in the primary studies affect valuation estimates much more than do sample characteristics the analysis of average preferences and dispersion of preferences indicates clear differences between regions furthermore region specific preferences diverge over time

measuring the relative importance of preferences for country of origin in china france niger and the united states recent labeling policies in developed countries place new focus on origin labeling especially country of origin labeling for a variety of food products it is not clear if this new emphasis on origin is the result of more ethnocentric consumer preferences for food we measure consumer preferences for country of origin in four different international locations and one domestic control location using a conjoint experiment to test the null hypotheses that consumers do not have stronger own country preferences in addition we compare the relative importance of consumer preferences for origin to their preferences for genetically modified food and pesticide free production using attribute coefficients from within location ordered probit models the study was conducted in china france niger and the united states we find consumers tend to prefer food from their own location indicating ethnocentric tendencies do play a role in shaping country of origin preferences country of origin is generally less important to consumers than genetically modified food content and pesticide use in food production
