In a credence goods game with an expert and a consumer, we study experimentally the impact of two devices that are predicted to induce consumer-friendly behavior if the expert has a propensity to feel guilty when he believes that he violates the consumerʼs payoff expectations: (i) an...

Expert opinions are often biased. To test how such bias affects the propensity to use opinions, we set up an experiment where subjects estimate the probability of an event that depends on (i) the subject's type, which is observable, and (ii) the unobserved state of the world. Before making their...

We investigate a private value auction in which a single “entrant” on winning imposes a negative externality on two “regular” bidders. In an English auction when all bidders are active, “regular” bidders free ride, exiting before price reaches their values. In a first-price...

We introduce noise in the signaling technology of an otherwise standard wasteful signaling model (Spence, 1973). We theoretically derive the properties of the equilibria under different levels of noise and we experimentally test how behavior changes with noise. We obtain three main insights....

We experimentally investigate the effect of social identification and information feedback on individual behavior in contests. In all treatments we find significant over-expenditure of effort relative to the standard theoretical predictions. Identifying subjects through photo display decreases...

This article reports the results of a laboratory experiment that examines the strategic effect of forward contracts on market power in infinitely repeated duopolies. Two competing effects motivate the experimental design. Allaz and Vila (1993) argue that forward markets act like additional...
