the role of reference prices in experimental auctions abstract we examine the role of reference prices field prices in willingness to pay studies involving experimental auctions using a 2nd price vickrey auction we find that provision of reference prices increases bid values

repeated rounds with price feedback in experimental auction valuation an adversarial collaboration it is generally thought that market outcomes are improved with the provision of market information as a result the use of repeated rounds with price feedback has become standard practice in the applied experimental auction valuation literature we conducted two experiments to determine how rationally subjects behave with and without price feedback in a second price auction results from an auction for lotteries show that subjects exposed to price feedback are significantly more likely to commit preference reversals however this irrationality diminishes in later rounds results from an induced value auction indicate that price feedback caused greater deviations from the nash equilibrium bidding strategy our results suggest that while bidding on the same item repeatedly improves auction outcomes this improvement is not the result of price feedback

where do we go from here 2 real wages effective demand and economic development a central purpose of this paper is to argue for a more active role for historical analysis in filling out and extending classical theory firstly what is required is a more modern vision of capitalist growth which would not only include such classical variables as the rate of profit and accumulation but also take into account the changing level and composition of the standard of living and how this interrelates with the compositional evolution of the industrial structure including the effect of new technology and changes in industrial organisation such as the development of new industries new products and new systems of marketing the second important need is for a more differentiated class analysis with which to study the growth process this would require a detailed consideration of the historical stratification and re stratification of the working class and would incorporate an analysis of the impact of and the interaction between the evolving industrial and political organisation of labour state policy collective bargaining the restructuring of labour resulting from changing power relations in the market and in the labour process changing technology and industrial organisation these processes have particular relevance in the present context for inter and intra class distribution of income and how this relates to the level and structuring of demand the paper consists of five main sections the first considers representative attempts to incorporate historical processes into theory the second considers the development in the structure of consumption in britain since 1860 the third links changing consumption to the standard of living the fourth examines the relationship between the standard of life and institutional developments in wage determination and in welfare provision and the fifth is a brief attempt to relate these factors to economic development

resolving differences in willingness to pay and willingness to accept reply gwendolyn c morrison 1997 raises a logical point regarding our experimental test of the divergence between willingness to pay wtp and willingness to accept wta measures of economic value shogren et al 1994 she argues that our design does not provide a true test of the existence of a fundamental endowment effect since we did not control for the potential of a pivoting indifference map daniel kahneman et al 1990 she concludes that even though our ev idence shows that the mean wtp and wta bids for market goods with close substitutes e g candy bars and coffee mugs converge after market experience the endowment effect might still be alive and well albeit at statisti cally insignificant levels

are airports engines of economic development a dynamic panel data approach this paper applies the dynamic panel data generalized method of moments estimator to the data on commercial passenger air traffic at all primary airports in the united states to evaluate the impact of traffic volume and number of destinations served with non stop flights on the key indicators of regional economic development we find that number of destinations served with non stop flights has a much clearer and more robust impact on level of employment number of business establishments and average wage in the region passenger traffic volume affects employment and average wage but not number of establishments at the sample median connecting a metropolitan statistical area with an extra destination keeping everything else constant creates 98 jobs and facilitates the opening of four new business establishments that employ people the corresponding numbers for the sample mean are 223 jobs and 15 businesses the impact of air travel on regional economic development is influenced by competition on the

moral dimensions of the wta wtp disparity an experimental examination abstract contrary to welfare economic theory empirical evidence suggests that the amount of money people are willing to accept wta to forego a commodity will generally exceed the amount of money they are willing to pay wtp to gain the commodity this paper undertakes an experimental examination of the wta wtp disparity using conventional and ecologically produced eggs the results of this experiment reveal that the difference between the mean wtp and wta for conventional eggs is negligible while the mean wta is more than 1 5 times higher than the mean wtp in the case of ecological eggs an explanation for this result is offered following the boyce et al boyce r b brown t c mcclelland g h peterson g l schulze w d 1992 an experimental examination of intrinsic values as a source of the wta wtp disparity am econ rev 82 1366 1373 notion that an asymmetrical assignment of moral responsibility may cause wta to exceed wtp by comparing the two studies a tentative conclusion is that the valuation disparity is likely to increase with a corresponding increase in the degree of assigned moral responsibility

divergence in alternative hicksian welfare measures the case of revealed preference for public amenities this paper investigates the divergence between the two hicksian welfare measures of non traded amenity improvement associated with housing first the hicksian surplus measures for amenity changes are analytically developed based on explicit specification of utility structures a hedonic two stage approach is then applied to empirically show that for quantity changes in contrast to hypothetical markets divergence in real market is small the paper also analytically develops expressions for the income and substitution effects and empirically shows that for a given income effect the greater the substitution effect the smaller the divergence between the two measures copyright 2002 john wiley sons ltd

recent trends in aggregate concentration in the united kingdom economy the extent to which large corporations dominate economic activity and the design of ap propriate policies towards them have been the subject of an extensive debate in the uk in recent years trends in concentration in manufacturing have played an important role in fuelling this debate recent studies however suggest that the unprecedented increases in overall or aggregate concentration in manufacturing which took place in the 1960s have not been repeated in the 1970s on the contrary concentration seems to have stabilised or fallen in the first half of the 1970s 1 in our view such estimates are not necessarily a good guide to the size and role of big business in the economy as a whole the discussion needs to be extended beyond the confines of manufacturing non manufacturing activity in the uk in the 1970s accounted for around 70 of gdp and over two thirds of employ ment 2 many of the largest uk companies including the oil companies the clearing banks and insurers and major retailers operate principally outside manufacturing and many of those within manufacturing have substantial non manufacturing interests as their consoli dated annual accounts reveal 3 mergers provide a more dramatic indication of this pattern in 1983 bat industries one of the ten largest industrial companies in the uk made a takeover bid for eagle star the sixth largest insurer whilst this may be an extreme example it is certainly the case that in the 1970s conglomerate mergers have generally become of far greater relative importance than they were in the 1960s 4 our object in this paper is therefore to provide recent estimates of aggregate concen tration which extend beyond manufacturing industry and cover the years 1968 82 this involves major problems because there are no official statistics to guide us we have there fore had to use a variety of published sources principally based on company accounts

pay and employment determination in britain what are labour contracts really like the recent growth of unemployment in western economies has prompted new research on the workings of the labour market there has been much interest in particular in the questions what determines the level of real pay and why is it apparently so insensitive to changes in aggregate demand and unemployment european economists now find it hard to take seriously the notion still taught to many undergraduate that wages are determined by the intersection of demand and supply curves roughly half of all british employees belong to trade unions a much higher percentage have their pay fixed by some kind of collective bargain in this country it is negotiations not impersonal com petitive markets which decide what most of us will be paid the difficult problem is that of how to understand this process or to put it differently of how to think up the right model of the world

price information and bidding behavior in repeated second price auctions examining panel data on bidding behavior in over forty second price auction markets with repeated trials we observe that i posted prices influence the behavior of the median naive bidder ii posted prices do not affect the behavior of the median experienced bidder or the bidder for familiar goods and iii anticipated strategic behavior wanes after two trials the results suggest that while affiliation might exist in auctions for new goods the repeated trial design with nonprice information removes the correlation of values and provides the experience that bidders need to understand the market mechanism

understanding the disparity between wtp and wta endowment effect substitutability or imprecise preferences abstract although it is now generally accepted that willingness to accept exceeds willingness to pay disagreement remains as to why this disparity is shown to persist even when controlling for learning substitutability and respondents imprecision thus lending further support for the endowment effect

5 information impact and allocation rules in auctions with affiliated private values a laboratory study in affiliated private value auctions each bidder has perfect information regarding his her own value for the object at auction but higher values of the item for one bidder make higher values for other bidders more likely we report on a series of experiments examining three key implications of these auctions i in a first price auction public information about rivals values increases expected revenue ii an english auction increases expected revenue compared to a first price auction and iii a second price auction is isomorphic to an english auction in examining these issues we compare predictions of some ad hoc bidding models with nash equilibrium predictions in the first price auction experiments nash equilibrium bidding theory organizes the data better than either of two ad hoc bidding models public information about others valuations does increase average revenue but the increase in revenue is smaller and less reliable than predicted under risk neutral nash equilibrium bidding lower average revenue might be attributed to risk aversion while the high variability is attributed to a sizable frequency of individual bidding errors relative to the theory bidding theory precisely organizes english auction outcomes after a brief initial learning period the dominant strategy equilibrium does not organize second price auctions nearly as well as market prices persistently exceed predicted prices the difference between english and second price outcomes is attributed to effects of different information flows inherent in the structure of the two institutions on eliminating bidding errors revenue impacts of these two institutions relative to a first price auction are examined in light of observed bidding patterns

auctions with a buy price the case of reference dependent preferences abstract in an auction with a buy price the seller provides bidders with an option to end the auction early by accepting a transaction at a posted price this paper develops a model of an auction with a buy price in which bidders use the auction s reserve price and buy price to formulate a reference price the model both explains why a revenue maximizing seller would want to augment her auction with a buy price and demonstrates that the seller sets a higher reserve price when she can affect the bidders reference price through the auction s reserve price and buy price than when she can affect the bidders reference price through the auction s reserve price only the comparative statics properties of bidding behavior are in sharp contrast to equilibrium behavior in other models where the existence and size of the auction s buy price have no effect on bidding behavior

posted prices and bid affiliation evidence from experimental auctions in most experimental auctions researchers ask participants to bid on the same item in multiple po tentially binding rounds posting the price submitted by the top bidder or bidders after each of those rounds if bids submitted in later rounds are affiliated with posted prices from earlier rounds this practice could result in biased value estimates in this article we discuss the results of an experiment designed explicitly to test whether posted prices affect bidding behavior we find that for familiar items high posted prices lead to increased bids in subsequent rounds our results have implications for researchers conducting experimental auctions article advances the literature in several im portant ways first we report the design and results of the only study designed specifically to control for the effects of posted prices on bids in subsequent rounds we do this with the aid of confederate bidders who were instructed to bid within a certain narrow range thus we have multiple treatments that vary only by the presence or absence of confederate bidders al lowing for what we believe to be the cleanest possible test of the effect of posted prices on bidding behavior in later rounds while list and shogren 1999 model bids in round t as a function of the posted price in round t 1 through our use of confederate bidders to con trol posted prices we are able to test whether exposure to high posted prices has an effect that accumulates over the course of multiple rounds leading to a gradual increase in mean bids second our methods of analysis are more complete than previous work examining bid af filiation we not only compare summary statis tics from early and late rounds but we also use panel data analysis to understand how in dividual participants bids are affected by the presence of confederate bidders focusing on individuals rather than summary statistics al lows us to understand how individual specific characteristics influence affiliation and it also allows us to better understand the role of out liers

market simulation and the provision of public goods a non paternalistic response to anomalies in environmental evaluation most normative economics assumes that individuals have coherent preferences this paper responds to growing evidence of failures of this assumption particularly in the context of stated preference methods widely used in environmental policy analysis it proposes a non paternalistic concept of consumer sovereignty that does not assume preference coherence is satisfied by competitive markets and can be applied to the provision of public goods a key implication is that decisions should reflect valuations revealed at the point of consumption such valuations which can be inferred from hedonic prices may be less susceptible to willingness to accept wta willingness to pay wtp disparities than those elicited by stated preference methods

tests of market outcomes with asymmetric valuations of gains and losses smaller gains fewer trades and less value abstract the pervasive finding that individuals value losses more than gains suggests that actual gains from trade and numbers of market exchanges may well be much smaller than would be the case if people s buying and selling prices were equivalent as normally assumed the results of two sets of costless market simulations using actual gain and loss valuations show that the actual gains from exchange and trade volumes are less than half of those expected with conventional assumptions and that completion of all pareto efficient exchanges fail by wide margins to shift entitlements to those willing to pay the most for them these findings suggest the valuation disparity has significant welfare implications and may be a major cause of market stickiness

which deceptive practices if any should be allowed in experimental economics research results from surveys of applied experimental economists and students deceptive experimental practices are banned in some professions but are standard in others recently the journals of the agricultural and applied economics association introduced guidelines that allow researchers to publish articles that use some forms of deception however in their present form these guidelines leave room for interpretation this situation is not ideal for researchers and a clearer definition of which deceptive practices should be banned could be beneficial our aim is to help provide greater clarity and potential guidance for journal policies regarding deception by using the results of surveys of both researcher and student subjects evaluating ten potentially deceptive experimental techniques we find consistent support for banning certain practices while allowing others

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

the impact of deal proneness on wtp estimates in incentive aligned value elicitation methods even after controlling for hypothetical biases some incentive aligned value elicitation methods still produce different willingness to pay wtp estimates in this study we compare wtp estimates from three incentive aligned value elicitation methods real choice experiment rce real double bounded dichotomous contingent valuation rcvm and becker degroot marschak auction bdm we find that participants aggressiveness in obtaining low prices i e deal proneness influences wtp estimates in the bdm auction but not those elicited from the rce and rcvm the participants with higher levels of deal proneness tend to submit lower bids in the bdm auction the discrepancies in wtp estimates between different incentive aligned procedures are narrower for participants with lower levels of deal proneness our results indicate that the bids in bdm auctions may be understated and the auction mechanism may induce the gambling behavior of people who are deal prone that is whether the bdm auction is truly incentive aligned is again called into question we also discuss the practical implications for food retailers

market power in a non monetarist inflation model for greece a post keynesian inflation model for greece is constructed and tested the model consists of three equations including a cost demand price equation for the gross domestic expenditure deflator cost demand functions have been occasionally estimated in the past the equation presented is a more systematic test since the effect of industry concentration is examined both theoretically and empirically a collective bargaining equation for the first time in greece was simultaneously estimated the role of public deficit was investigated and it was found that this exerts a moderate influence on inflation

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

markets and the measurement of value consumer s surplus and the hicksian measures of compensating and equivalent variation have a long history in empirical economic analysis however at both the theoretical and the empirical level economists psychologists and public choice theorists have not been able to reach a significant consensus regarding the usefulness of these measures economic theorists have only recently dissected the differences which exist between alternative welfare measures in a systematic and transparent fashion in willig 1976 hausman 1981 and takayama 1984 the role of income in determining the correct theoretical measurements of compensating and equivalent variations was exposed during this same period of time theoretical results obtained by the psychologists kahneman and tversky 1979 indicated that the fundamental structure of preferences upon which the theoretical economic results are based is flawed the so called prospect theory of decision developed by these authors indicated that measured of welfare based upon payment will differ from measures of welfare based upon compensation because of the fact that individuals will value losses at a greater marginal rate than gains this difference was then predicted to dominate any income effect important in the economist s model finally this period recorded the emergence of many demand revealing processes which provide individuals with appropriate incentives to accurately reveal their preferences as summarized in coursey and schulze 1986 one interpretation of the literature on incentive compatibility suggests a set of well defined guidelines for improving both the accuracy and validity of compensating and equivalent variation measures these differences in professional preferences regarding what is important in improving the accuracy of economic welfare measurements led john

valuing an eu animal welfare label using experimental auctions the aim of this article is to determine consumers valuation for an eu animal welfare eu caw label for products providing higher animal welfare standards than the current legal requirements using revealed preference data from random nth price auction mechanism and two auction procedures our results generally suggest that consumers are willing to pay a premium for an eu animal welfare eu caw label for cured ham this finding is consistent in both the endowment and full bidding auction approaches we employed in our experiments conducted in spain the average premium that consumers are willing to pay for a cured ham with the eu caw label ranges between 19 and 23 of the average price of the regular cured ham that is currently available in supermarkets

willingness to pay and willingness to accept how much can they differ comment i agree with the point made by edoh y amiran and daniel a hagen 2003 that there can be a substantial or even infinite divergence between the wta and wtp for a public good even where there is a nonzero elasticity of substitution between market goods and the public good provided that the indifference curves are asymptotically bounded with respect to market goods in the manner they describe this is an important point they are also correct to point out that the elasticity of substitution is a local concept whereas their asymptotic boundedness condition applies also for discrete changes my 1991 paper used a local analysis because it was following the structure of the analysis in robert d willig 1976 and alan randall and john r stoll 1980 i wanted to show that while randall and stoll appeared to extend willig s local result on wta versus wtp from price changes to changes in the quantity of a public good the relevant elasticity was in fact different and involved the substitution elasticity as well as the income elasticity i view these points by amiran and hagen as not two separate results but essentially the same result their asymptotic boundedness condition generalizes my zero elasticity of substitution condition to discrete changes the asymptotic boundedness condition can be expressed as follows assuming a bivariate utility function u x q and given a reference point x q associated with a reference utility level u u x q there exists some q q such that for all q q there exists no x such that u x q u in other words no amount of x can substitute for the reduction in public good from q to q q in the case of a zero elasticity of substitution q q but as amiran and hagen show in their theorem 1 this is unnecessarily restrictive when dealing with a discrete reduction in q furthermore their theorem 2 can be viewed as a special case of their theorem 1 in which q 0 which makes q an essential commodity it is well known in consumer theory that the wta to avoid the loss of an essential market good is infinite their theorem 2 extends this result to the case of an essential nonmarket good but as their theorem 1 shows essentialness is not necessary for an infinite wta the boundedness condition is the key and this implies a fundamental lack of substitutability between money market goods and the public good

airfreight transport and economic development an examination of causality the paper examines the potential role that airfreight transport in the us can play in stimulating local and regional economic development the analysis examines trends in employment and income for metropolitan statistical areas that make use of airfreight services the focus is on causality and not on simple correlation and uses econometric analysis rather than simpler economic multiplier approaches granger causality testing based on panel data covering 35 airport and 32 metropolitan statistical areas in the us from 1990 to 2009 indicates that airfreight transport was a positive driver for local economic development the conclusions focus on the strengths but also the weaknesses of the methodology for assessing causality

information and the divergence between willingness to accept and willingness to pay abstract there is considerable empirical and experimental evidence that there is a divergence between willingness to accept compensation to give up a good and willingness to pay to obtain a good this divergence persists even when the good in question is small relative to income a result in apparent conflict with standard economic theory this paper develops a theoretical bidding model with costly information acquisition to explain this divergence the model generates a gap between offers to sell and bids to buy consistent with the experimental results we argue that the model does a better job of explaining empirical and experimental data than either of the two commonly invoked theoretical explanations the endowment effect and the substitution effect

price discontinuities in an online market for used cars we study the price setting behavior in a competitive market for used cars and provide empirical evidence for coarse information processing based on detailed field data from one of europe s largest online marketplaces for automotive vehicles we document systematic and sizable price discontinuities at salient car age and mileage thresholds the price difference between two otherwise identical cars across registration years where one was first registered in january and the other in december of the previous year is up to five times larger than that between two cars first registered in any two subsequent months within a registration year a similar pattern can be observed in the mileage dimension at 10 000 km odometer marks which is in line with earlier findings in the literature being able to study discontinuities along two dimensions of the same good allows us to further our understanding toward a more general notion of inattentive behavior while our results are compatible with a behavioral model of l

is public expenditure productive abstract this paper considers the relationship between aggregate productivity and stock and flow government spending variables the empirical results indicate that i the nonmilitary public capital stock is dramatically more important in determining productivity than is either the flow of nonmilitary or military spending ii military capital bears little relation to productivity and iii a core infrastructure of streets highways airports mass transit sewers water systems etc has most explanatory power for productivity the paper also suggests an important role for the net public capital stock in the productivity slowdown of the last fifteen years

consumer s surplus without apology the purpose of this paper is to settle the controversy surrounding consumer s surplus and by so doing to validate its use as a tool of welfare economics i will show that observed consumer s surplus can be rigorously utilized to estimate the unobservable compensating and equivalent variations the correct theoretical measures of the welfare impact of changes in prices and income on an individual i derive precise upper and lower bounds on the percentage errors of approximating the compensating and equivalent variations with consumer s surplus these bounds can be explicitly calculated from observable demand data and it is clear that in most applications the error of approximation will be very small in fact the error will often be overshadowed by the errors involved in estimating the demand curve the results in no way depend upon arguments about the constancy of the marginal utility of income consequently this paper supplies specific empirical criteria which can replace the apologetic caveats frequently employed by those who presently apply consumer s surplus moreover the results imply that consumer s surplus is usually a very good approximation to the appropriate welfare measures to preview below i establish the validity of these rules of thumb for a

benefit evaluation of the country of origin labeling in taiwan results from an auction experiment this research is aimed at investigating the consumer s preference for food produced in taiwan and the economic benefits for the country of origin labeling cool the study used vickrey second price sealed bid auction to elicit the consumer s willingness to pay wtp for products under cool the study compared the bid functions estimated with tobit model and the premium functions estimated with ordinary least squares ols due to price affiliation it is more reliable to use the estimated premium functions the estimated premiums are 67 5 84 7 and 99 for taiwan products over their alternatives of china olives china oolong tea and vietnam oolong tea respectively the study concludes that enacting and rigorously enforcing a cool law would increase economic benefits to consumers in taiwan and at the same time placing the imported products in the leveled playing field

why does unemployment persist the main movements of unemployment correspond to fluctuations in the short run nairu around a stable long term nairu these supply side fluctuations have two main origins i variations in the number of insiders involved in wage setting ii variations in the effectiveness of the unemployed outsiders as potential job seekers the evidence of micro studies suggests that ii is more important than i and this also helps to explain the widespread shift outwards in the u v curve to derive these arguments rigorously the paper presents a simple model of efficiency wages another of collective bargaining and finally a fully dynamic model with labour market flows

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

despairing over disparities explaining the difference between willingness to pay and willingness to accept this paper examines the three major explanations for the disparity between willingness to pay wtp and willingness to accept wta observed in contingent value surveys and laboratory experiments a belief that the results must be biased in some fashion hanemann s 1991 substitutes hypothesis and the loss aversion model proposed by tversky and kahneman 1991 starting from the assumption that individuals make utility maximizing choices we develop structural equations that yield parametric tests of the hypotheses within a single non experimental framework the approach is flexible enough to incorporate a variety of functional form and distributional assumptions and can be applied to either data from either open ended bids or dichotomous choice questions the usefulness of the approach is demonstrated using data from a survey that asked both wtp and wta questions the results provide weak support for loss aversion

the relationship between inflation and the budget deficit in turkey this article analyzes the empirical relationship between inflation and the budget deficit for the turkish economy by a multivariate cointegration analysis a single equation model shows that the scaled budget deficit as well as income growth and debt monetization significantly affects inflation in turkey the conditional model of inflation is constant and it encompasses a previously estimated model

does production labeling stigmatize conventional milk production labeling is a common approach for differentiating otherwise similar products in the marketplace while these labels may convey positive messages to consumers about the new product they may simultaneously stigmatize the conventionally produced product by highlighting perceived problems the net economic result for producers can be negative since consumers may decrease their willingness to pay for the conventional product that dominates the market while the new product has a relatively small market share this experimental research identifies this stigma effect in the case of milk where the introduction of rbst free and organic milk reduces consumers willingness to purchase conventional milk copyright 2009 oxford university press

willingness to pay and compensation demanded experimental evidence of an unexpected disparity in measures of value aside from possible income effects measures of the maximum amounts people will pay to avoid a loss and the minimum compensation necessary for them to accept it are generally assumed to be equivalent unexpectedly wide variations between these sums however have been noted in survey responses to hypothetical options this paper reports the results of a series of experiments that confronted people with actual money payments and cash compensations the results indicate that the compensation measure of value seems to exceed significantly the willingness to pay measure which would appear to call into some question various rules of entitlement damage assessments and interpretations of indifference curves

a canonical model of choice with initial endowments we use the revealed preference method to derive a model of individual decision making when the endowment of an agent provides a reference point that may influence her choices this model generalizes the classical rational choice model which views choice as a consequence of utility maximization instead our model sees choice as arising from psychologically constrained utility maximization where the constraints are induced by one s initial endowment in particular this model produces status quo bias as a natural consequence but not necessarily the endowment effect a range of economic applications identify the predictive and explanatory strength of the model in particular we demonstrate that the status quo bias phenomenon reduces the size of the substitution effect in problems of consumption choice

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

willingness to pay for natural organic and conventional foods the effects of information and meaningful labels vague food labels and distorted product claims have persisted in the natural food industry while organic claims can be certified by the u s department of agriculture usda using experimental methods and a sample of randomly selected subjects we test food label and information treatment effects on subjects willingness to pay wtp for organic natural and conventional foods random nth price auctions are used to elicit wtp after subjects received one of five randomly assigned information treatments we find large information effects including asymmetric cross market effects for natural and organic foods perhaps surprising is that organic premiums increase in response to subjects seeing the natural foods industry s perspective on its products demographics effects are also important the results have practical implications for natural and organic food marketing and valuing products where there are vague claims about their attributes
