Retributive responses do play a role in human behavior. Whether they are primarily triggered by supposed intentions or by observed consequences of actions is an important question. It can be addressed by experimental studies of retributive responses in situations in which the individual actor...

We report on an experiment designed to explore the interrelation of other-regarding concerns with attitudes towards risk and delay when the latter have a social dimension, i.e., pertain to one's own and another person's payoffs. For this sake, we compare evaluations of several prospects, each of...

This article examines the nature of human behavior in a nested socialdilemma referred to as the Spillover Game. Players are divided into twogroups with positive production interdependencies. Based on theoreticallyderived opportunistic, local, and global optima, our experimental...

Are commonly known beliefs essential for bidding behavior in asymmetric auctions? Our experimental results suggest that not informing participants how values are randomly generated does not change behavior much and may even make it appear more rational.

Most research in economics models agents somehow motivated by out-comes. Here, we model agents motivated by procedures instead, whereprocedures are dened independently of an outcome. To that end, wedesign procedures which yield the same expected outcomes or carry thesame information on other's...

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 important extensions of the standard...

Although one may hope to achieve equality of stated profits withoutenforcing it, one may not trust in such voluntary equality seeking andrather try to impose rules (of bidding) guaranteeing it.[...]
