We correlate competitive bidding and profits in symmetric independent private value first-price auctions with salivary testosterone, estradiol, progesterone, and cortisol in more than 200 subjects. Females bid significantly higher and earn significantly lower profits than males. Moreover,...

In an experiment using two-bidder first-price sealed bid auctions with symmetric independent private values, we collected information on the female participants' menstrual cycles. We find that women bid significantly higher than men in their menstrual and premenstrual phase but do not bid...

We analyze subjects' eye movements while they make decisions in a series of one-shot games. The majority of them perform a partial and selective analysis of the payoff matrix, often ignoring the payoffs of the opponent and/or paying attention only to specific cells. Our results suggest that...

Opinion is divided on whether it is better to have a single world money or variable exchange rates.Pope, Selten and von Hagen (2003) propose that fresh light would be shed via an analysis that allows forseven complexity impacts on the exchange rate that are underplayed (where not entirely...

The distinct historical and cultural experiences of American blacks and whites may influence whether members of those groups perceive a particular exchange as fair. We investigate racial differences in fairness standards using preferences for equal treatment in the ultimatum game, where...

We show in a public goods experiment on three continents that conditional cooperation is a universal behavioral regularity. Yet, the number of conditional cooperators and the extent of conditional cooperation are much higher in the U.S.A. than anywhere else. -- conditional cooperation ; public...

We report results from a replication of Solnick (2001), which finds using an ultimatum game that, in relation to males, more is demanded from female proposers and less is offered to female responders. We conduct Solnick's (2001) game using participants from a large US university and a large...

We report results from a sender-receiver deception game, which tests whether an individual's decision to deceive is influenced by a concern for relative standing in a reference group. The sender ranks six possible outcomes, each specifying a payoff for him and the receiver. A message is then...

We experimentally investigate the nature of cooperation in various repeated games, with subjects from Romania and USA. We find stark cross-country differences in the propensity to sustain multilateral cooperation through bilateral rewards and punishments. U.S. groups perform well because...
