We explore the effects of social distance in experiments conducted over the Internet on three continents, in classroom laboratory sessions conducted in Israel and Spain, and in computer sessions pairing participants from different states-one in Texas and the other in California. Our design...

Departures from "economic man" behavior in many games in which fairness is a salient characteristic are now well documented in the experimental economics literature. These data have inspired development of models of social preferences that assume agents have preferences for equity and efficiency...

We examine experimentally the impact of communication on trust and cooperation. Our design admits observation of promises, lies, and beliefs. The evidence is consistent with people striving to live up to others' expectations in order to avoid guilt, as can be modeled using psychological game...

Participants in experimental games typically can only choose actions, without making comments about other participants' future actions. In sequential two-person games, we allow first movers to express a preference between responder choices. We find that responder behavior differs substantially...

The standard procedure in experimental economics maintains anonymity among participants. Yet, many field interactions are conducted with neither complete anonymity nor complete familiarity. How will people respond to varying degrees of anonymity and social distance? We consider the effect of one...

We test an assortative mechanism whereby groups are formed endogenously, through the use of voting. Once formed, groups play a public-goods game, where the social value of an incremental contribution to the group account increases with the size of the group. Societies of nine people are...

We study experimentally a two-stage compensation mechanism for promoting cooperation in prisoner's dilemma games. In stage 1, players simultaneously choose binding non-negative amounts to pay their counterparts for cooperating in a given prisoner's dilemma game, and then play the prisoner's...

This paper investigates experimentally the impact of reciprocal fairness considerations in multilateral bargaining and coalition formation. The consequences for effciency and the distribution of wealth are analyzed. The results show that reciprocal fairness indeed deeply affects the effciency...

This paper reports the results of experiments involving a 3-person coalition formation game with an ultimatum bargaining character. The grand coalition was always the efficient coalition decision, whereas the values of the 2-person coalitions are varied such that they lead to an efficiency loss...

The question of whether lawyers and managers behave selfishly or fairly has inspired discussion for a long time. Empirical evidence, however, is sparse. Using data from an experiment with 359 law and business administration students, we investigate this question empirically and provide first...
