How does a group’s gender composition influence its decisions? Economists have found women to be more generous and egalitarian than men, so one might expect groups with more women to be more generous/egalitarian. Group polarization, whereby discussions amplify preexisting attitudes (a...

We examine experimentally how a person's generosity depends on the <p> sex of that person, on the sex of the person who is the target of the <p> generous act, and on the degree of anonymity between the interacting parties. <p> In our data fewer men than women give non-zero amounts; men receive less than <p>...</p></p></p></p>

We perform a (psychological) game-theoretic analysis of cheating in the setting proposed by Fischbacher & Föllmi-Heusi (2013). The key assumption, which we refer to as perceived cheating aversion, is that the decision maker derives disutility in proportion to the amount in which he is perceived...

Tacit cartels did not arise in experimental triopoly markets even with the help of detailed instructions to prospective cartel members on how to coordinate actions. In duopoly markets tacit cartels were successful, with winning bids and supporting "pass" bids increasing gradually. A simulated...

People cooperate more in one-shot interactions than can be explained by standard textbook preferences. We discuss a set of non-standard preferences that can accommodate such behavior. They are social, in the sense of incorporating the payoffs of other persons; they are also norm-based, in the...

Counterfeiting of trademarked products is an increasing problem in national and international trade. We contribute to the analysis of how counterfeiting affects markets by extending the work of Grossman and Shapiro (1988a) on consumption externalities in prestige good markets. We model a general...

We explore gender differences in preferences related to altruism, fairness, cooperation, trust, coordination, risk and competitiveness in an experiment with a large random sample of the Swedish population. In addition to a baseline treatment, we have treatments where participants are primed with...
