an incentive aligned mechanism for conjoint analysis abstract this article specifies analyzes and validates a rigorous and practical truth telling mechanism game for conjoint applications the mechanism requires only one real product variation and has truth telling in conjoint as its bayesian nash equilibrium thus making it possible to incentive align participants in most conjoint applications using the ipod package as the context the author shows empirically that the mechanism substantially improves purchase prediction compared with a standard conjoint procedure

are consumption taxes really better than income taxes abstract we use political equilibrium theory and the neoclassical growth model to compare consumption and income tax systems if government outlays are used for redistribution through transfers then steady state equilibria in societies that use income taxes are not necessarily worse in welfare terms and may even be better income taxes are attractive precisely because they are more distortionary since this implies low equilibrium transfer levels we also find that switching tax systems typically does not benefit the median voter moreover a change from income to consumption taxes may make everybody worse off

stochastic dominance and mean variance measures of profit and loss for business planning and investment in this paper we first extend the stochastic dominance sd theory by introducing the first three orders of both ascending sd asd and descending sd dsd to decisions in business planning and investment to risk averse and risk loving decision makers so that they can compare both return and loss we provide investors with more tools for empirical analysis with which they can identify the first order asd and dsd prospects and discern arbitrage opportunities that could increase his her utility as well as wealth and set up a zero dollar portfolio to make huge profit our tools also enable investors and business planners to identify the third order asd and dsd prospects and make better choices to complement the stochastic dominance approach we also introduce an improved mean variance criterion to decisions in business planning or investment on both return and loss for risk averse and riskloving investors we then illustrate the superiority of the present approaches with well known examples in the literature and discuss the relationship between the improved stochastic dominance and mean variance criteria

stated preferences over job characteristics a panel study when making choices over jobs with different characteristics what trade offs are decision makers willing to make such a question is difficult to address using typical household surveys that provide a limited amount of information on the attributes of the jobs to address this question a small but growing number of studies have turned to the use of stated preference experiments but the extent to which stated choices by respondents reflect systematic trade offs across job characteristics remains an open question we use two popular types of experiments profile case best worst scaling and multi profile case best worst scaling to elicit job preferences of nursing students and junior nurses in australia each person participated in both types of experiments twice within a span of about 15 months using a novel joint likelihood approach that links a decision maker s preferences across the two types of experiments and over time we find that the decision makers make similar trade offs across job characteristics in both types of experiments and in both time periods except for the trade off between salary and other attributes the valuation of salary falls significantly over time relative to other job attributes for both types of experiments also within each period salary is less valued in the profile case compared to the more traditional multi profile case

consumer preference for a no choice option the traditional focus in the decision making literature has been on understanding how consumers choose among a given set of alternatives the notion that preference uncertainty may lead to choice deferral when no single alternative has a decisive advantage is tested in seven studies building on recent research the article shows that the decision to defer choice is influenced by the absolute difference in attractiveness among the alternatives provided and is not consistent with trade off difficulty or the theory of search these findings are then extended to show that choice deferral can also be modified for the same alternatives by manipulations that make them appear more similar in attractiveness or that decrease the need to differentiate among them the results are consistent with the notion that preference uncertainty results in a hesitation to commit to any single action since small differences in attractiveness among the alternatives are potentially reversible consistent with this premise the effect of attractiveness difference on choice deferral decreased significantly when subjects were first allowed to practice making monetary trade offs among the available alternatives

when more is less and less is more the role of ideal point availability and assortment in consumer choice contrary to the common wisdom that more choice is always better selections made from large assortments can lead to weaker preferences building on the extant literature this research identifies ideal point availability as a key factor moderating the impact of assortment on choice it is proposed that in the case of large assortments ideal point availability can simplify choice leading to a stronger preference for the selected alternative in contrast for choices made from smaller assortments ideal point availability is proposed to have the opposite effect leading to weaker preferences data obtained from four experiments lend support for the theory and the empirical predictions advanced in this article

incentive aligned conjoint analysis abstract because most conjoint studies are conducted in hypothetical situations with no consumption consequences for the participants the extent to which the studies are able to uncover true consumer preference structures is questionable experimental economics literature with its emphasis on incentive alignment and hypothetical bias suggests that more realistic incentive aligned studies result in stronger out of sample predictive performance of actual purchase behaviors and provide better estimates of consumer preference structures than do hypothetical studies to test this hypothesis the authors design an experiment with conventional hypothetical conditions and parallel incentive aligned counterparts using chinese dinner specials as the context the authors conduct a field experiment in a chinese restaurant during dinnertime the results provide strong evidence in favor of incentive aligned choice conjoint analysis in that incentive aligned choice conjoint outperforms hypothetical choice conjo

are choice experiments incentive compatible a test with quality differentiated beef steaks this study compares hypothetical and nonhypothetical responses to choice experiment questions we test for hypothetical bias in a choice experiment involving beef ribeye steaks with differing quality attributes in general hypothetical responses predicted higher probabilities of purchasing beef steaks than nonhypothetical responses thus hypothetical choices overestimate total willingness to pay for beef steaks however marginal willingness to pay for a change in steak quality is in general not statistically different across hypothetical and actual payment settings

testing commitment cost theory in choice experiments in choice experiments it is commonly assumed that individuals make choices in static and certainty decision making conditions real world choices however are usually made in a dynamic setting committing a purchase decision under conditions of uncertainty might have a commitment cost cc in this study we test cc theory using a nonhypothetical choice experiment specifically we test whether choice behavior and willingness to pay estimates differ when individuals have the option to gain present or delayed information or reverse the transaction our results suggest that the construction of a dynamic decision context can be relevant in the design of choice experiments

do investors like to diversify a study of markowitz preferences we study rankings of completely and partially diversified portfolios and also of specialized assets when investors follow so called markowitz preferences it turns out that diversification strategies for markowitz investors are more complex than in the case of risk averse and risk inclined investors whose investment strategies have been extensively investigated in the literature in particular we observe that for markowitz investors preferences toward risk vary depending on their sensitivities toward gains and losses for example it turns out that unlike in the case of risk averse and risk inclined investors markowitz investors might prefer investing their entire wealth in just one asset this finding helps us to better understand some financial anomalies and puzzles such as the well known diversification puzzle which notes that some investors tend to concentrate on investing in only a few assets instead of choosing the seemingly more attractive complete diversification

paying politicians theory and evidence this paper looks at the theory behind the idea that paying politicians better will improve their performance the paper lays out a political agency model with adverse selection and moral hazard where politicians are subject to two period term limits this model provides a number of predictions about how the pay of politicians affects agency problems we also consider what happens when the pool of politicians is endogenous the main ideas in the model are confronted with data on u s governors jel d72 j33

how closely do hypothetical surveys and laboratory experiments predict field behavior we compare the ability of three preference elicitation methods hypothetical choices nonhypothetical choices and nonhypothetical rankings and three discrete choice econometric models the multinomial logit mnl the independent availability logit ial and the random parameter logit rpl to predict actual retail shopping behavior in three different product categories ground beef wheat flour and dishwashing liquid overall we find a high level of external validity our specific results suggest that the nonhypothetical elicitation approaches especially the nonhypothetical ranking method outperformed the hypothetical choice experiment in predicting retail sales we also find that the rpl can have superior predictive performance but that the mnl predicts equally well in some circumstances experiment

would you choose your preferred option comparing choice and recoded ranking experiments previous research has shown that results from a choice experiment are statistically different from those obtained from a ranking experiment that is recoded and treated as a choice experiment using only the first rank by avoiding some of the shortcomings of previous comparisons we obtain the opposite results using data from the valuation of a cork oak reforestation program in the south of spain structural models and welfare estimations are statistically indistinguishable irrespective of the use of parametric or bootstrapping tests further we employ follow up questions and subsample analysis to test whether divergences appear when potential effects are isolated copyright 2008 oxford university press

fiscal restraints and voter welfare this paper explores the logic of fiscal restraints in a political agency model with both moral hazard and adverse selection the role of the political process is both to discipline incumbents who may act against the public interest and to sort in those politicians who are most likely act in voters interests we use the model to examine the optimality of inefficient taxation limits on the size of government increasing transparency and yardstick competition some conclusions are surprising for example we show that some forms of fiscal restraint can only be desirable when incumbents are sufficiently likely to be benevolent

are results from non hypothetical choice based conjoint analyses and non hypothetical recoded ranking conjoint analyses similar conflicting findings have been found in previous research that compared choice based conjoint analysis and ranking conjoint analysis in a public good setting the present paper revisits this issue for a private good in a non hypothetical context using small and large choice sets our results suggest that in a small choice set setting participants preferences and willingness to pay are similar across the two conjoint analysis formats however in large choice sets a divergence between the two conjoint analysis formats emerges hence the two conjoint analysis formats can only be used interchangeably in small choice sets not in large choice sets

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

an incentive compatible conjoint ranking mechanism a simple method for making ranking based conjoint analysis incentive compatible is proposed the incentive compatible mechanism involves people purchasing a product profile with a probability proportional to its assigned rank in an empirical application related to consumer preferences for beef attributes we find that the forecasted market share for a new pasture raised steak obtained using incentive compatible rankings was significantly greater than that implied from traditional hypothetical conjoint rankings people s rankings of ground beef products were not affected by the mechanism or by information about pasture raised beef copyright 2008 oxford university press

choice modelling approaches a superior alternative for environmental valuation in this paper we examine some popular choice modelling approaches to environmental valuation which can be considered as alternatives to more familiar valuation techniques based on stated preferences such as the contingent valuation method a number of choice modelling methods are consistent with consumer theory and its focus on an attribute based theory of value permits a superior representation of many environmental management contexts however choice modelling surveys can place a severe cognitive burden upon respondents and induce satisficing rather than maximising behavioural patterns in this framework we seek to identify the best available choice modelling alternative and investigate its potential to solve some of the major biases associated with standard contingent valuation we then discuss its use in the light of policy appraisal needs within the eu an application to the demand for rock climbing in scotland is provided as an illustration

prospect theory and mean variance analysis the experimental results of prospect theory pt reveal suggest that investors make decisions based on change of wealth rather than total wealth that preferences are s shaped with a risk seeking segment and that probabilities are subjectively distorted this article shows that while pt s findings are in sharp contradiction to the foundations of mean variance mv analysis counterintuitively when diversification between assets is allowed the mv and pt efficient sets almost coincide thus one can employ the mv optimization algorithm to construct ptefficient portfolios the markowitz 1952a tobin 1958 mean variance mv rule is probably the most popular investment decision rule under uncertainty in economics and in finance and it is widely employed by both academics and practitioners the strength of the mv analysis is that in the case of normal return distributions the choice of any expected utility maximizing risk averse individual will be according to the mv rule 1 the mv framework is the foundation of the sharpe 1964 lintner 1965 capital asset pricing model capm which is a cornerstone of modern finance moreover the mv framework provides a very important practical procedure for the construction of efficient portfolios while standard economic theory and in particular mv analysis assume expected utility maximization and risk aversion in a breakthrough article kahneman and tversky 1979 show that the actual behavior of individuals systematically and consistently violates these

prospect theory much ado about nothing prospect theory is a paradigm challenging the expected utility paradigm one of the fundamental components of prospect theory is the s shaped value function the value function is mainly justified by experimental investigation of the certainty equivalents of prospects confined either to the negative or to the positive domain but not of mixed prospects which characterize most actual investments we conduct an experimental study withmixed prospects using for the first time recently developed investment criteria called prospect stochastic dominance psd and markowitz stochastic dominance msd we reject the s shaped value function showing thatat least 62 76 of the subjects cannot be characterized by such preferences we find support for the markowitz utility function which is a reversed s shaped function exactly the opposite of the prospect theory value function it is possible that the previous results supporting the s shaped value function are distorted because the prospects had only positive or only negative outcomes presenting hypothetical situations which individuals do not usually face and which are certainly not common in financial markets

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

stochastic dominance via quantile regression with applications to investigate arbitrage opportunity and market efficiency abstract tests for stochastic dominance constructed by translating the inference problem of stochastic dominance into parameter restrictions in quantile regressions are proposed they are variants of the one sided kolmogorov smirnoff statistic with a limiting distribution of the standard brownian bridge the procedure to obtain the critical values of our proposed test statistics are provided simulation results show their superior size and power they are applied to the nasdaq 100 and s p 500 indices to investigate dominance relationship before and after major turning points results show no arbitrage opportunity between the bear and bull markets our results infer that markets are inefficient and risk averters are better off investing in the bull rather than the bear market

theories of risk testing investor behaviour on the taiwan stock and stock index futures markets investor behavior towards risk lies at the heart of economic decision making in general and modern investment theory and practice in particular this paper uses both the mean variance mv criterion and stochastic dominance sd procedures to analyze the preferences for four of the most widely studied investor types in the taiwan stock and stock index futures market we find that risk averters concave utility function prefer spot to futures whereas risk seekers convex utility function prefer futures to spot our findings also show that investors with s shaped utility functions prefer spot futures to futures spot when markets move upward downward finally our results imply that investors with reverse s shaped utility functions prefer futures spot to spot futures when markets move upward downward these results are robust with respect to sub periods spot returns including dividends and diversification although we do not check whether risk averters risk seekers and investors with s shaped and reverse sshaped utility functions actually exist in the market we do show that their existence is plausible the implications of our findings on market efficiency and the existence of arbitrage opportunities are also discussed in this study

variety vice and virtue how assortment size influences option choice assortment size has been shown to influence whether consumers make a choice but could it also influence what they choose five studies demonstrate that because choosing from larger assortments is often more difficult it leads people to select options that are easier to justify virtues and utilitarian necessities are generally easier to justify than indulgences consequently choosing from larger assortments often shifts choice from vices to virtues and from hedonic to utilitarian options these effects reverse however when situational factors provide accessible reasons to indulge underscoring the role of justification implications for choice difficulty and justification processes are discussed

great expectations assortment size expectations and satisfaction abstract recent research challenges the idea that greater choice is always desirable showing that larger assortments can increase choice deferral and switching the current research demonstrates that even when consumers make a purchase the same item may generate lower satisfaction when chosen from a larger rather than a smaller assortment the authors explain this effect in terms of an expectation disconfirmation mechanism when assortments are small consumers have low expectations about their ability to match their preferences as assortment sizes increase so do consumers expectations of the degree of preference match they can achieve subsequently consumers may experience greater negative expectation disconfirmation or less positive expectation disconfirmation when a chosen item comes from a larger rather than a smaller set either less positive or more negative disconfirmation leads to lower choice satisfaction the results from three studies support this expectation based process and establish t
