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...

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....

Punishment typically involves depriving violators of resources they own such as money or labor. These resources can become revenue for authorities and thus motivate profit-seeking punishment. In this paper, we design a novel experiment to provide direct evidence on the role punishment plays in...

We analyse pricing, effort and tipping decisions at the online service ‘Google Answers’. Users set a price for the answer to their question ex ante, and they can additionally tip the researcher who provided the answer ex post.

Rule learning posits that decision makers, rather than choosing over actions, choose over behavioral rules with different levels of sophistication. Rules are reinforced over time based on their historically observed payoffs in a given game. Past works on rule learning have shown that when...
