    Abstract: The overarching goal of nutrition labeling is to transform credence attributes into searchable cues, which would enable consumers to make appropriate choices at lower search costs. However, despite an abundance of food labeling information, asymmetries regarding appropriate healthy food choices largely persist. Thus, there is need for research that exposes consumer’s label usage and their level of concern about their health in order to understand the underlying motivations that may explain consumer behavior with regard to labels. In order to better understand how current food-health behavior and related perceptions over potential future health complications are affected by present labeling usage patterns, this study will estimate 1) the impact of nutrition label usage on individual’s perceived diet health concerns using alternative propensity score matching (PSM) techniques; 2) the effect of nutrition label usage on consumer’s stated concerns on (a) diet-health, (b) obesity, and (c) general future wellbeing controlling for a wide variety of socio-demographic variables, food-intake and choice related behaviors, and lifestyles factors; and 3) conduct a series of tests and sensitivity analyses to assure robustness of matching indicators and to validate impacts of treatment effects for label users and non-users. The analysis utilizes data from the 2008 National Health and Wellness Survey conducted by Nielsen Canada. As the results suggest, consumers are not aware or use nutrition labeling information. In order to change dietary behavior, policy makers may need to adopt instruments that account for differences with regard to food preferences, food shopping habits, and overall usage patterns of food/nutrition labeling information.

    Abstract: This article examines consumers’ preference for three types of orange juice in China. Two non-hypothetical experiments, Real Choice Experiments and Experimental Auctions were used in the study. We found that WTP estimates from real choice experiment are significantly higher than auction bids, which is consistent with what Lusk and Schroeder (2006) and Gracia, Loureiro, and Nayga (2011) found in their paper. In addition, we found that purchase intention only has significantly effects on consumers’ behavior in Experimental Auction, but not in Real Choice Experiments, and this purchase intention only has effects on non-novel food, but not novel food.

    Abstract: Previous research on the relation between oxytocin and trustworthiness evaluations has yielded inconsistent results. The current study reports an experiment using artificial faces which allows manipulating the dimension of trustworthiness without changing factors like emotions or face symmetry. We investigate whether (1) oxytocin increases the average trustworthiness evaluation of faces (level effect), and/or whether (2) oxytocin improves the discriminatory ability of trustworthiness perception so that people become more accurate in distinguishing faces that vary along a gradient of trustworthiness. In a double blind oxytocin/placebo experiment (N = 106) participants conducted two judgment tasks. First they evaluated the trustworthiness of a series of pictures of artificially generated neutral faces. Next they compared neutral faces with artificially generated faces that were manipulated to vary in trustworthiness. The results indicate that oxytocin (relative to a placebo) does not affect the evaluation of trustworthiness in the first task. However, in the second task, misclassification of untrustworthy faces as trustworthy occurred significantly less in the oxytocin group. Furthermore, oxytocin improved the discriminatory ability of untrustworthy, but not trustworthy faces. We conclude that oxytocin does not increase trustworthiness judgments on average, but that it helps people to more accurately recognize an untrustworthy face.

    Abstract: The field of experimental economics is past its 50th anniversary and is celebrating its 2nd Nobel prize winner. By far the largest number of economic experiments are now conducted in computer labs, although there is a wide array of settings, ranging from pen-and-paper to elaborate field settings. The controlled environment of the computer lab remains a strong foothold for experimental research. On top of the high level of control, including the standardisation of recruitment protocol and software used, the ease of data collection singles out the lab environment as a key instrument for the testing of economic theory and market mechanics. A number of tools and procedures have developed over the recent decades shaping how experiments are conducted. Z-tree (Fischbacher, 2007) has been established as the quasi-standard tool to conduct experiments. This paper introduces a novel view on how to approach programming for experiments, specifically it introduces a number of innovations from professional software development into the programming of economic experiments. Finally the lightweight experimental software framework CORAL will be introduced.

    Abstract: This paper studies monitoring and punishment behavior by second and third parties in a cooperation experiment with endogenous information structures: Players are uninformed whether the target player cooperated or defected at the cooperation stage, but can decide to resolve the information imperfection at non-negative cost at the punishment stage. We examine how monitoring and punishment respond to changes in monitoring costs, and exploit the evidence to gain new insights about commonalities and differences between second and third party behavior. We establish three effects of positive monitoring costs relative to the zero-cost baseline and find that each one affects third parties differently than second parties: A «direct punishment cost effect» (the supply of non-strategic punishment decreases), a «blind punishment effect» (players punish without resolving the information imperfection) and a «diffusion effect» (defectors make up a smaller share of the punished and receive weaker punishment). The first effect affects third parties less, the other two more. As a result, third party punishment leads to increasingly weaker incentives for cooperation relative to second party punishment as monitoring costs rise. In addition, the differences between second and third parties suggest the presence of a «pure role effect»: Taking into account elicited beliefs and risk preferences, third parties punish differently from second parties, not just more weakly.

    Abstract: We show that people have difficulty valuing annuities, and this, instead of a preference for lumpsums, helps explain observed low annuity demand. Although the median price at which people are willing to sell an annuity stream is close to the actuarial value, many responses diverge greatly from optimizing behavior. Moreover, people will pay substantially less to buy than to sell annuities. We conclude that boundedly rational consumers adopt “buy low, sell high” heuristics when confronting a complex trade-off. This suggests that many consumers do not make optimizing decisions, underscoring the difficulty of explaining cross-sectional annuity valuation differences using standard models.

    Abstract: In this paper we conduct a series of eld experiments in rural India in order to measure preferences related to risk, loss, and ambiguity. Disaggregating by data, we nd that on average women are signicantly more risk averse and loss averse than men, though the higher average risk aversion arises due to a greater share of women who are extremely risk averse. Through a series of two empirical examples, we demonstrate how these parameters aect decisions to adopt new agricultural technologies. By combining these results with a choice experiment over new and familiar rice seeds, we nd that ambiguity averse individuals are far more likely to stick with seeds they are familiar with, while a greater degree of loss aversion generally suggests people are more willing to switch to a new variety.

    Abstract: This article examines the preferences revealed by two non-hypothetical experiments. We found that WTP estimates from real choice experiment are significantly than auction bids. We provide two possible reasons for it: consumers’ purchase intention and aggressiveness in price bargaining. Our results suggest that the discrepancies among experiments can come from the heterogeneity of respondents’ price bargaining aggressiveness, but not from purchase intention differences.

    Abstract: This paper studies whether people can avoid punishment by remaining willfully ignorant about possible negative consequences of their actions for others. We employ a laboratory experiment, using modified dictator games in which a dictator can remain willfully ignorant about the payoff consequences of his decision for a receiver. A third party can punish the dictator after observing the dictator’s decision and the resulting payoffs. On the one hand, willfully ignorant dictators are punished less if their actions lead to unfair outcomes than dictators who reveal the consequences before implementing the same outcome. On the other hand, willfully ignorant dictators are punished more than revealing dictators if their actions do not lead to unfair outcomes. We conclude that willful ignorance can circumvent blame when unfair outcomes result, but that the act of remaining willfully ignorant is itself punished, regardless of the outcome.

    Abstract: We study the role of status in an experimental Principal-Agent game.Status is awarded to subjects based on either talent or luck. In each randomly matched principal-agent pair, the principal chooses the agent's status-contingent piece rate for a task in which talent matters for performance (an IQ test). We perform the experiment in Cambridge (UK) and in HCMV (Vietnam). We find that in Cambridge piece rate others are significantly higher for high-status agents (only) when status signals talent. However, these higher offers are not payoff-maximizing for the principals.In contrast, Vietnam piece rate offers are significantly higher for high-status agents (only) when status is determined by luck. We explore possible explanations, and the implications for status and incentives.

    Abstract: We present an axiomatic model of choice involving two agents, motivated by the experimental evidence on non-selfish preferences. We distinguish two classes of social preferences, depending on whether they are or not separable. Altruism and spite (Andreoni & Miller, 2002; Cox et al., 2007) are separable, while the various forms of inequality aversion are not (Fehr & Schmidt, 1999; Bolton & Ockenfels, 2000; Charness & Rabin, 2002). Separable and non-separable preferences give very close predictions when only sure outcomes are involved, but they make opposite predictions in choices involving lotteries. We show this by proposing a generalization of expected utility that accounts for preferences for “fair procedures”, which violate the independence axiom. An experimental test of the model reveals little evidence of ex-post inequality aversion, even when non-expected utility preferences are accounted for.

    Abstract: In premium auctions, the highest losing bidder receives a reward from the seller. This paper studies the private value English premium auction (EPA) for different risk attitudes of bidders. We explicitly derive the symmetric equilibrium for bidders with CARA utilities and conduct an experimental study to test the theoretical predictions. In our experiment, subjects are sorted into risk-averse and risk loving groups. We find that revenues in the EPA are significantly higher when bidders are risk loving rather than risk averse. These results are partly consistent with theory and confirm the general view that bidders’ risk preferences constitute an important factor that affects bidding behavior and consequently also the seller’s expected revenue. However, individual subjects rarely follow the equilibrium strategy and as a result, revenue in our experiment is lower than in the symmetric equilibrium.
    Keywords: premium auction; risk preference; Holt-Laury method; experimental economics.
