asymmetries in price and quantity adjustments by the competitive firm focusing on the crucial role of inventory carry overs in the production and sales decision we describe the profit maximizing behavior of a dynamic competitive firm facing random prices each firm s behavior is incorporated into a stochastic equilibrium model of the competitive industry with uncertain demand the industry model exhibits asymmetric cyclical fluctuations of the keynesian sort when demand is weak output contracts while price holds at a fixed floor when demand is strong price increases as output is constrained by a ceiling even in a pure world of constant returns without increasing costs the inability to instantaneously coordinate production and sales along with the existence of inventories is sufficient to yield a backward i shaped supply curve for the short run journal of economic literature classification numbers 020 021 022

multiperiod sales production decisions under uncertainty abstract this paper studies the behavior of an expected profit maximizing multiperiod firm under uncertainty in output and demand the firm s problem is to determine in each period the level of sales and inventory and the expected output for the coming period the optimal policy is derived in an explicit closed form and is proved to be myopic it is shown that the observed phenomenon of downward price inflexibility can be explained and further specified by using the results of our model

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

how much is too much an investigation of the effect of the number of choice sets context dependence and the choice of bid vectors in choice experiments in a split sample design we examine how the number of choice sets design of the first choice set context dependence and the choice of attribute levels in the cost attribute affect the precision in the elicited preferences in otherwise completely identical choice experiment surveys these issues are investigated for swedish households marginal willingness to pay to reduce power outages our results indicate that neither the number of choice sets nor the design of the first choice set has a significant impact on estimated marginal willingness to pay while the effect was significant for the additive scaling of the cost vector at the end of the article we discuss the implications of our results on future developments and applications of choice experiments

ordering effects and choice set awareness in repeat response stated preference studies we present an experiment designed to investigate the presence and nature of ordering effects within repeat response stated preference sp studies our experiment takes the form of a large sample full factorial discrete choice sp exercise investigating preferences for tap water quality improvements our study simultaneously investigates a variety of different forms of position dependent and precedent dependent ordering effect in preferences for attributes and options and in response randomness we also examine whether advanced disclosure of the choice tasks impacts on the probability of exhibiting ordering effects of those different types we analyze our data both non parametrically and parametrically and find robust evidence for ordering effects we also find that the patterns of order effect in respondents preferences are significantly changed but not eradicated by the advanced disclosure of choice tasks a finding that offers insights into the choice behaviors underpinning order effects

modelling heterogeneity in response behaviour towards a sequence of discrete choice questions a probabilistic decision process model there is a growing body of evidence in the non market valuation literature suggesting that responses to a sequence of discrete choice questions tend to violate the assumptions typically made by analysts regarding independence of responses and stability of preferences decision processes or heuristics such as value learning and strategic misrepresentation have been offered as explanations for these results while a few studies have tested these heuristics as competing hypotheses none has investigated the possibility that each explains the response behaviour of a subgroup of the population in this paper we make a contribution towards addressing this research gap by presenting a probabilistic decision process model designed to estimate the proportion of respondents employing defined heuristics we demonstrate the model on binary and multinomial choice data sources and find three distinct types of response behaviour the results suggest that accounting for heterogeneity in response behaviour may be a better way forward than attempting to identify a single heuristic to explain the behaviour of all respondents

causes for an asymmetric relation between the price of crude oil and refined petroleum products we revisit the issue of asymmetries in the relation between the price of crude oil and refined petroleum products in the united states an econometric analysis of monthly data indicates that the asymmetric relation between the price of crude oil and motor gasoline is generated by refinery utilization rates and inventory behavior the asymmetric relation between the price of crude oil and home heating oil probably is generated by contractual arrangements between retailers and consumers together these results imply that price asymmetries may be generated by efficient markets under these conditions there is little justification for policy interventions to reduce or eliminate price asymmetries in motor gasoline and home heating oil markets

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

inventories rational expectations and the business cycle abstract the simplest macroeconomic models in which markets clear instantaneously and expectations are rational preclude the existence of business cycles that is of serially correlated deviations of output from trend this paper studies one of several mechanisms that can be used to make these so called new classical models produce business cycles the mechanism is the gradual adjustment of inventory stocks two macroeconomic models of inventory holdings are formulated both imply first that current output should be a decreasing function of the stock of inventories and second that inventories once perturbed from equilibrium levels should adjust only gradually these two features are then embedded into an otherwise standard macroeconomic model in which markets clear instantaneously and expectations are rational two principal conclusions are reached first disturbances such as unanticipated changes in money will set in motion serially correlated deviations of output from trend second if desired inventories are sensitive to the real interest rate then even fully anticipated changes in money can affect real variables

contracts delivery lags and currency risks abstract this paper presents a competitive model in which exchange rate uncertainty has real effects on how trade contracts are written and executed in this model exporting firms have an incentive to delay delivery on trade contracts whenever they can sell their products on the domestic market for a higher price than the domestic currency value of the price specified by the trade contracts in general it is costly for a firm to offer a credible commitment to the promised delivery date of a trade contract we demonstrate that under certain conditions a firm can costlessly commit to a policy of no delivery lags by the appropriate choice of the currency of denomination of trade contracts

asymmetric price adjustments a supply side approach using a model of dynamic price competition we provide an explanation from the supply side for the well established observation that output prices react faster in response to input cost increases than to decreases when costs decline the opportunity of profitable storing in anticipation of higher future costs allows competitive firms to coordinate on prices above current marginal costs the initial price response is only partial and profitable storing relaxes competition conversely when costs rise storing is not beneficial in anticipation of lower future costs and firms immediately adjust their prices to current marginal costs which entails the standard bertrand outcome our results shed new light on the empirical evidence about asymmetric pricing and can stimulate further empirical investigation on this puzzle

vertical price transmission in the egyptian tomato sector after the arab spring this study assesses price transmission along the egyptian tomato food marketing chain in the period that followed the arab spring which accentuated economic precariousness in egypt static and tim

incentive incompatibility and starting point bias in iterative valuation questions we test for incentive incompatibility and starting point bias to describe the effects of iterative valuation questions on willingness to pay we compare double triple and multiplebounded models with data from two surveys with similar designs of the valuation questions we find that incentive incompatibility is present in both sets of data and starting point bias is present in one the efficiency of the willingness to pay estimate is improved in only one set of data the potential loss from using iterative questions without controlling for both incentive incompatibility and starting point bias is biased willingness topay estimates

preference anomalies preference elicitation and the discovered preference hypothesis there is wide ranging evidence much of it deriving from economics experiments of anomalies in behaviour that challenge standard preference theories this paper explores the implications of these anomalies for preference elicitation methods because methods that are used to inform public policy such as contingent valuation are based on standard preference theories their validity may be called into question by the anomaly data however on a new interpretation these anomalies do not contradict standard theory but are errors in stated preference that can be expected to disappear as people become more experienced in relevant decision environments we explore the evidence for this interpretation and what implications follow for preference elicitation methodology

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

price dynamics in a vertical sector the case of butter we develop a reduced form model of price transmission in a vertical sector allowing for refined asymmetric contemporaneous and lagged own and cross price effects under time varying volatility the model is used to investigate the wholesale retail price dynamics in the u s butter market the analysis documents the nature of nonlinear price dynamics in a vertical sector it finds strong evidence of asymmetric retail price responses both in the short term and the longer term but only weak evidence of asymmetric wholesale price responses asymmetric retail responses play a major role in generating a skewed distribution of butter prices the empirical results indicate the presence of imperfect competition at the retail level

a learning design for reducing hypothetical bias in the contingent valuation method over the last few years a great deal of research has focussed on hypothetical bias in value estimates obtained with the contingent valuation cv method and on means for ameliorating if not eliminating such bias to date efforts to eliminate hypothetical bias have relied on calibration techniques or on word smithing of one kind or another to induce subjects to provide responses to hypothetical questions that mimic responses made by subjects facing actual payments in the valuation experiment this paper introduces a different approach for eliminating hypothetical bias a design for a cv survey format is presented which provides subjects with the opportunity to learn how the cv institution works sequential referenda are conducted where respondents gain experience in cv settings by participating in both hypothetical and real referenda the logic of this learning design is a straightforward application of the trials process used in experimental economics we demonstrate that the learning design is effective in eliminating hypothetical bias in surveys concerning donations to two different public goods

information effects in contingent markets information bias in contingent markets is poorly understood in this paper testable hypotheses concerning beneficial contingent market information effects are developed conceptually perspective information and relative expenditure information were expected to increase comprehension and increase bids provision cost information was expected to counteract free riding behavior and also increase bids hypothesis tests using experimental markets suggested that each information type induced small statistically insignificant bid increases however the combined effect of the three information types induced a desirable statistically significant increase in bids this result supports the contention that not all contingent market information effects are biases

anomalies and stated preference techniques a framework for a discussion of coping strategies this paper introduces a symposium on the issue of how stated preference sp research can best cope with anomalies i e systematic deviations from the predictions of standard economic theory in survey responses it proposes a framework for constructive debate recognising i the legitimate aspirations of sp research ii the relevance of evidence from sources other than best practice sp and iii the precautionary value of investigating strategies for coping with suspected anomalies even if questions about the robustness of anomalies have not been finally resolved five alternative coping strategies discussed in more detail in the symposium are briefly introduced

soybean inventory and forward curve dynamics we present two results concerning soybean prices first we exhibit a simple relationship between stocks and price volatility the observation of an increasing price volatility with decreasing inventory is often mentioned in the literature but has so far been documented using a proxy for inventory see fama and french 1987 1988 litzenberger and rabinowitz 1995 instead we reconstruct a yearly quarterly and monthly database of worldwide soybean inventories using aggregate data from the united states brazil and argentina we show that under all time scales price volatility is an increasing linear function of inverse inventory which we term scarcity second we show how the addition of the factor scarcity in a state variable approach to the dynamics of the term structure of soybean forward prices improves the quality of the fit we document this property on a 25 year database of cbot futures contracts and show that the superior accuracy also affects long maturity futures contracts an important property for the valuation of long term origination contracts between producing countries and the agrifood industry

trading off positive and negative service changes in childcare a choice experiment using a latent class modelling approach theoretically the choice of childcare mode should be influenced by the quality of the childcare attributes however such preference relations have been difficult to identify in past studies one

determination of employment with wage and price speculation the purpose of this paper is to investigate whether aggregate fluctuations in employment may be explained within a market clearing framework as intertemporal substitution in labor supply and demand an intertemporal substitution model for the firm is derived this model is estimated with a lucas rapping type supply equation empirical results with finnish data lend support to the intertemporal substitution model particularly concerning the demand function specification on the other hand the results for the supply equation are somewhat mixed being rather sensitive to the dynamic specification

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

the effects of information on willingness to pay values of endangered species the contingent valuation method cvm has been employed in several research studies to measure the economic value of environmental commodities brookshire kramer and mercer loehman park and boldt lohr battard and bath the use of cvm allows for flexibility and for application to a wide range of environmental amenities not only those that can be measured in conjunction with some marketable goods however because of its hypothetical character the validity of cvm is often disputed a structural element that might have an especially strong influence on cvm valuation is the contingent market information structure bergstorm stoll and randall information content and presentation in contingent markets are controlled by the researcher the design of an information structure can influence a participant s cognitive valuation process and in turn final revealed valuations information is thus conceptualized as an input into the cognitive decision process of which stated valuations are the final result the role of information in a contingent valuation methodology is extremely important because it conveys the knowledge of an environmental issue with which the respondent will assimilate and base value judgment on this research study proposes that information disclosure can influence an individuals reported willingness to pay wtp values for the preservation of an endangered species the means by which information is disclosed by the researcher is critical in the valuation process new information disclosed about an ecological good might affect the wtp behavi r of the individuals kula

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

choosing between internet and mail survey modes for choice experiment surveys considering non market goods in a choice experiment setup considering a non market good this paper adds to the literature on survey mode effects by providing evidence that internet surveys can be a viable alternative to traditional mail surveys when gathering feedback from a sample of respondents the case study concerns preferences for protecting different types of landscape from road encroachment when building new motorways in denmark two samples of respondents are surveyed one by internet and one by mail the performances of the two samples are compared over six different criteria response rates protest responses demographics preferences and wtp estimation precision and finally certainty in choice differences are observed for some of these criteria implying that analysts should be aware that choosing internet over mail could be accompanied by a survey mode effect however the observed differences do not translate into significant differences in the unconditional wtp estimates in most applied economic valuation studies of non market goods the main objective is in fact estimation of wtp hence in the present case the identified survey mode effects do not severely invalidate the applicability and continued use of the internet as a suitable means of collecting data for choice experiment economic valuation of non market goods

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

price transmission and local market power empirical evidence from the austrian gasoline market we analyse the impact of local market power on price margins and different dimensions of price adjustment dynamics speed and asymmetry of price transmission using data for a large number of indiv

the effect of ethanol policies on the vertical price transmission in corn and food markets this paper analyzes the impact of ethanol policies on price transmission along the food supply chain we consider the us corn sector and its vertical links with food and ethanol energy markets we find that ethanol is a source of imperfect price transmission in the food supply chain ethanol however alters price transmission only under a binding blender s tax credit and only from food to corn not vice versa our results indicate that ethanol weakens the response of corn and food prices in terms of their level changes to shocks occurring in agricultural corn and food markets the results are robust to different assumptions on the model parameters although market power has previously been identified as a source of imperfect price transmission in the food supply chain our findings show that in the presence of ethanol the imperfect price transmission may occur even if markets are perfectly competitive this warrants careful evaluation of markets before any policy intervention

the effects of changing cost vectors on choices and scale heterogeneity choice experiments ce are widely used to estimate the values of changes in non market goods and services a cost attribute is typically included in a ce questionnaire to enable the estimation of monetary values for changes in the non market attributes presented notwithstanding the central importance of the cost attribute relatively little research has been undertaken on the impacts of varying cost attribute levels on value estimates or on individual heterogeneity in this paper i present results from mixed logit and generalised mixed logit models that account for unobserved idiosyncratic preference and scale heterogeneity respondents are found to anchor their choices on the relative cost levels presented in the survey with results suggesting that people are more sensitive to relative rather than absolute cost vectors however the higher cost levels do not lead to significantly higher value estimates partly because of observed preference heterogeneity towards the environmental attributes an important observation is that scale heterogeneity is important accounting for scale as well as preference heterogeneity in the generalised mixed logit model leads to significantly improved model fit the results indicate significant unobserved error variance across respondents unrelated to whether a high or low cost vector is used

starting point bias in dichotomous choice valuation with follow up questioning abstract follow up questions are frequently used to improve the efficiency of dichotomous choice contingent valuation questionnaires however a number of authors e g 12 16 have noted a significant difference between the wtp distributions implied by initial and follow up question responses this paper investigates starting point bias as one explanation for the phenomenon we develop a model of starting point bias in the context of dichotomous choice questioning with follow up using a monte carlo simulation to illustrate the potential bias imparted to wtp estimates an application is provided based on data from a cv study in northcentral iowa

a general model of starting point bias in double bounded dichotomous contingent valuation surveys abstract this paper develops a general model that addresses the starting point bias in the dichotomous choice evaluation data by incorporating both the anchoring effect and yea saying bias the model is applied to a contingent valuation study that evaluated the health benefits of air quality improvement in three major metropolitan areas in taiwan the empirical evidence shows a strong anchoring effect but an insignificant yea saying bias the results show a serious understated willingness to pay if the biases in anchoring and yea saying are not controlled

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

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

probabilities vs money a test of some fundamental assumptions about rational decision making this paper describes an experiment where respondents were asked to tackle two decision tasks which were very similar in structure but which differed in that one problem involved direct money payoffs while the other involved payoffs in the form of probabilities of winning a given sum of money according to most decision models most risk averse individuals might be expected to behave quite differently under the two conditions but the behaviour actually observed does not accord with this expectation the paper discusses possible reasons for this and the potential implications of such findings the central proposition in this paper is that much of the effort that has gone into developing formal decision models to explain individual decision making under risk and uncertainty may to some possibly considerable extent have been misdirected in section 1 this proposition is elaborated sections 2 and 3 report a new experiment designed to address the key issues directly the results lend further weight to the central proposition the concluding remarks discuss some possible implications and lines of future research 1 background most decision theorists would regard the pioneering work of von neumann and morgenstern 1944 and savage 1954 and the establishment of the expected utility eu paradigm as being the most important development this century in modelling behaviour under risk and uncertainty yet it was not long before other researchers were drawing attention to a number of apparently systematic patterns of behaviour which seemed to run directly counter to one or more of the basic eu axioms allais 1953 ellsberg 1961 lichtenstein and slovic 1971 and kahneman and tversky 1979 are notable examples observing the ease with which those patterns could be replicated and noting their robustness in the face of determined attempts to eliminate them a number of theorists interpreted these behavioural regularities as outward expressions of sophisticated and highly articulated preferences which do not

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

the context for substitutes in cvm studies some empirical observations abstract the purpose of this paper is to report results from a set of experiments that provide data to test the noaa 13 panel recommendation that subjects be reminded of budgetary substitutes when providing values the results suggest that simply reminding subjects of alternative environmental goods does not affect the distribution of values for a specific good such values are affected however whenever subjects simultaneously value alternative goods

learning and fatigue effects revisited investigating the effects of accounting for unobservable preference and scale heterogeneity using multiple choice tasks per respondent in discrete choice experiment studies increases the amount of available information however respondents learning and fatigue may lead to changes in observed utility function preference taste parameters as well as the variance in its error term scale they need to be controlled to avoid potential bias a sizable body of empirical research offers mixed evidence in terms of whether these ordering effects are observed we point to a significant component in explaining these differences we show how accounting for unobservable preference and scale heterogeneity can influence the magnitude of observed ordering effects

choke price bias in choice experiments this paper reports on the results from a split sample choice experiment where the effect of changing the maximum level of the cost attribute is investigated the hypothesis was that changing the maximum price level would either give rise to an income effect or have no effect on consumers preferences this was tested in the framework of a valuation study of different quality characteristics of minced pork the data was analysed using a mixed logit error component model which accounts for correlation in the unobserved part of the utility results suggest that the size of the maximum price level does matter and that changing the maximum price level has a statistically significant effect on both the general preferences structure and the wtp estimates hence researchers should be very careful when defining not only the range of the price attribute but also the maximum level of the price attribute

new evidence on asymmetric gasoline price responses in a 1997 paper borenstein cameron and gilbert bcg claim that gasoline prices rise quickly following an increase in the price of crude oil but fall slowly following a decrease this note estimates an error correction model with daily spot gasoline and crude oil price data over the period 1985 1998 and finds no evidence of asymmetry in wholesale gasoline prices the sources of the difference in results are twofold first we use the standard engle granger two step estimation procedure whereas bcg used a nonstandard estimation methodology second even using bcg s nonstandard specification the use of daily rather than weekly data yields little evidence of price asymmetry

the state of the art of environmental valuation with discrete choice experiments abstract this paper provides with a review of the state of the art of environmental valuation with discrete choice experiments dces the growing body of literature on this field serves to emphasize the increasing role that dces are playing in environmental decision making in the last decade the paper attempts to cover the full process of undertaking a choice experiment including survey and experimental design econometric analysis of choice data and welfare analysis the research on this field is found to be intense although many challenges are put forward e g choice task complexity and cognitive effort experimental design preference and scale heterogeneity endogeneity or model uncertainty reviewing the state of the art of dces serves to draw attention to the main challenges that this methodological approach will need to overcome in the coming years and to identify the frontiers in discrete choice analysis

preferences for site and environmental functions when selecting forthcoming national parks abstract a political decision to establish the first ever national parks in denmark allowed us to examine if people hold preferences regarding which site to be designated as national park separate from the preferences for its environmental functions to this end we designed a choice experiment representing the national park alternatives by the possible site and the possible improvements in environmental functions results revealed that respondents have strong preferences for the establishment of a national park per se furthermore there are significant differences in taste parameters for the different sites which cannot be explained by respondents valuing the different functions differently across sites instead we explain the results with differences in regional and cultural preferences we also performed a balanced split sample test of anchoring effects and found clear evidence of this we included a zero bidder screening question prior to the choice set part of the survey instrument to improve wtp estimation

the effects of consumers price expectations on sellers dynamic pricing strategies abstract the authors propose a dynamic market equilibrium model to investigate how consumers form price expectations and how these expectations influence their sequential search behavior and prices in the market they derive a perfect bayesian nash equilibrium and show that whereas higher current period prices induce search consumers who observe higher historical prices form higher price expectations become more pessimistic and search less furthermore the authors show that when prices increase as a result of an increase in marginal costs consumers respond by searching more which then leads to higher prices and instant price adjustment in contrast because consumer search activities decline when prices fall sellers may respond by lowering their prices just enough to dampen consumers search tendencies when costs decrease the authors test their theoretical model and its implications and find support for it in a series of simulated market experiments

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

position dependent order effects on the prediction of consumer preferences in repeated choice experiments abstractusing stated choice data collected by experimental design with repeated choice tasks this study developed an approach to quantify the position dependent order effects on the prediction of

the stylized facts about the behavior of manufacturers inventories and backorders over the business cycle 1959 1980 recent theoretical work has highlighted the role of inventories in propagating business cycles this paper attempts to provide an empirical foundation for current and future research on the role inventories play in business cycles the evidence presented here indicates that inventories and backorders are major variables in predicting output fluctuations further the evidence is that disaggregating inventories by stage of fabrication is important in predicting output in concert with previous findings our results suggest that disaggregated inventories ought to be a component of models of the business cycle

changing with the tide semiparametric estimation of preference dynamics we contrast the discovered preference hypothesis against the theory of coherent arbitrariness in a split sample stated choice experiment on flood risk exposure a semiparametric local multinomial logit model is developed as an alternative to the swait and louviere 1993 test procedure controlling for preference dynamics within and between samples the proposed model supports the discovered preference hypothesis by means of a decaying starting point bias the swait and louviere 1993 test procedure reaches a different conclusion it rejects the assumption of stable preferences but most preference dynamics tend to be smoothed out causing a more erratic pattern of preference dynamics

coherent arbitrariness stable demand curves without stable preferences economic theories of valuation generally assume that prices of commodities and assets are derived from underlying fundamental values for example in finance theory asset prices are believed to reflect the market estimate of the discounted present value of the asset s payoff stream in labor theory the supply of labor is established by the tradeoff between the desire for consumption and the displeasure of work finally and most importantly for this chapter consumer microeconomics assumes that the demand curves for consumer products chocolates cds movies vacations drugs and so forth can be ultimately traced to the valuation of pleasures that consumers anticipate receiving from these products because it is difficult as a rule to measure fundamental values directly empirical tests of economic theory typically examine whether the effects of changes in circumstances on valuations are consistent with theoretical prediction for example whether labor supply responds appropriately to a change in the wage rate whether compensated demand curves for commodities are downward sloping or whether stock prices respond in the predicted way to share repurchases however such comparative static relationships are a necessary but not sufficient condition for fundamental valuation e g summers 1986 becker 1962 was perhaps the first to make this point explicitly when he observed that consumers choosing commodity bundles randomly from their budget set would nevertheless produce downward sloping demand curves

optimal inventories and equilibrium price behavior abstract this paper departs from the established tradition of equilibrium inventory theory by examining the relationship between inventories and market prices when production is instantaneous but distribution is costly inventory holdings are not buffer stocks and do not facilitate production smoothing rather production variability exceeds the variability of final sales voluntary holdings of marketable finished goods are not restricted to occasional speculation during periods of unexpectedly low demand but may persist even when capital losses are anticipated in these respects the paper reconciles important features of the inventory decision problem with the results of modern investment theory

long and short run price asymmetries and hysteresis in the italian gasoline market abstract using monthly data from 1994 to 2013 we study the long run relation of the pre tax retail prices of gasoline with crude price and the nominal exchange rate we find a strongly significant long run relation we then use the nonlinear ardl nardl model to assess the asymmetries on both the short and long run elasticities as well as the presence of hysteresis in the pricing behaviour the estimation results confirm the presence of asymmetry in the long run elasticities with significant differences between the crude price and the exchange rate as well as the presence of hysteresis in the relation between the retail price of gasoline and crude oil price

do gasoline prices respond asymmetrically to crude oil price changes the authors test and confirm that retail gasoline prices respond more quickly to increases than to decreases in crude oil prices among the possible sources of this asymmetry are production inventory adjustment lags and market power of some sellers by analyzing price transmission at different points in the distribution chain the authors attempt to shed light on these theories spot prices for generic gasoline show asymmetry in responding to crude oil price changes which may reflect inventory adjustment effects asymmetry also appears in the response of retail prices to wholesale price changes possibly indicating short run market power among retailers
