Teams are shown to violate the most basic of equilibrium refinements in signaling games: single-round deletion of dominated strategies (part of the Cho–Kreps intuitive criteria). This is important because, to the extent that teams can be easily induced to violate the most basic of equilibrium...

Charness et al. (2007b) have shown that group membership has a strong effect on individual decisions in strategic games when group membership is salient through payoff commonality. In this comment I show that their findings also apply to non-strategic decisions, even when no outgroup exists, and...

In this paper, we report the results of experiments designed to test whether individuals and groups abide by the axioms of monotonicity, with respect to first-order stochastic dominance and Bayesian updating, when making decisions in the face of risk. The results indicate a significant number of...
