In an experiment, we first elicit the distributional preferences of subjects and then let them bid for a lottery, either in a Becker–DeGroot–Marschak (BDM) mechanism or a Vickrey auction (VA). The standard theory predicts that altruistic subjects underbid in the VA—compared to the BDM—while spiteful subjects overbid in the VA. The data do not confirm those predictions. While we observe aggregate underbidding in the VA, the result is not driven by the choices of altruistic subjects.

Economic experiments often entail subjects making decisions with payoffs in experimental currency units (ECUs). Earnings in ECUs are converted to cash at the end of the experiment. Such a procedural choice seems to be driven more by habit or tradition than by empirical evidence that this is more appropriate to use. We report results of a private, induced value second price auction (SPA) experiment in which we manipulate the exchange rate between ECUs and cash. We find virtually no relationship between a stronger/weaker experimental currency and the ability of theory to predict observed outcomes. The only significant effect relates to the comparison of the cash-only condition to the one-to-one exchange condition. The latter produced greater behavioral deviations from theoretical predictions. However, we find that this effect is largely driven by a handful of subjects. The results suggest that the use of ECUs is not a hindrance for experimental practice, at least not in the context of an induced value SPA.

Produce that does not meet sellers’ esthetic standards may be redirected to alternative uses or wasted, but consumer trends indicate potential marketability of blemished produce. We conduct a nonhypothetical experimental auction to elicit consumer willingness-to-pay (WTP) for produce of varying degrees of blemish and test whether valuations are affected by (1) information on food waste resulting from grocery stores’ esthetic standards and (2) additional information on the environmental impacts of food waste. WTP for blemished produce increases as consumers become informed, but the information effects vary by blemishing degree. Market simulations indicate that introducing blemished produce can increase retailer revenue.
