In this experiment I study a novel three-player ultimatum game in which two proposers with unequal amounts of money simultaneously submit offers to one responder, who may accept at most one offer. I compare the predictions of inequity aversion, advantage seeking, and self-interest. Unlike...

We analyze experimental data obtained from an ultimatum game framed as a situation of employee–employer negotiation over salaries. Parallel to this, we elicit subjects’ risk attitudes. In the existing literature, it has often been conjectured that gender differences in strategic environments...

Humans often lie strategically. We study this problem in an ultimatum game with an informed proposer and an uninformed responder, where the former can send an unverifiable statement about his endowment. A simple message game with heterogenous players with respect to lying costs shows that in...

Combining the methodologies of experimental economics and molecular genetics, we report a genetic association between sex-hormone genes and ultimatum game (UG) behavior in a discovery sample from China and a replication sample from Israel. The androgen receptor gene is found to be associated...

Take-it or leave-it offers are probably as old as mankind. Our objective here is, first, to provide a, probably subjectively colored, recollection of the initial ultimatum game experiment, its motivation and the immediate responses. Second, we discuss extensions of the standard ultimatum...

We report results from an Ultimatum Game experiment with and without pre-play communication, conducted both in a real-world experimental laboratory and in the virtual world Second Life. In the laboratory, we replicate previous results that communication increases offers and agreement rates...

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

Group membership is a powerful determinant of social behaviour in a variety of experimental games. Its effect may be channelled primarily via the beliefs of group members, or directly change their social preferences. We report an experiment with a prisoner's dilemma with multiple actions, in...

We set up an experiment to study whether disclosure of the advisor's interests can foster truthfulness and trust. We measure how advisors expect decisionmakers to react to their advice in order to distinguish between strategic and moral reactions to disclosure by advisors. Results indicate that...

We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare consultation to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our benchmark...
