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...

Several experimental studies on altruism have found women to be more generous than men. We investigate whether observed gender gaps in generosity can be explained by experimental setting, where some settings are more conducive than others to activating gender identity and social norms. In a...

An experiment is designed to test if individuals show (unrealistic) optimism when determining their subjective probabilities about exogenous circumstances. Subjects in the control group make an informed guess about a number, under a payment scheme that rewards close guesses. In the treatment...

This paper first presents stylised evidence showing how the date of the introduction of competition policy is correlated with country size. Smaller countries tend to adopt competition policy later. We thereafter present a simple theoretical model with countries of different size and firms...

The paper examines the impact of income inequality and mobility on income redistribution in a modified median voter model where redistributive conflict takes place both between educational groups and age-groups. The effects of inequality and mobility are not unambiguous but depend on factors...

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>
