Abstract

We test for behavioral differences between groups and individuals in gift-exchange experiments. Related studies in economics establish group behavior as often closer to the standard game-theoretic equilibrium under the assumptions of rationality and selfishness. We show that this result may depend crucially on the decision making procedure within groups and the nature of the task. A novel experimental decision making protocol opens the black box of group decision making and allows tracking important features of the group interaction process. We are also able to show that acting in a group may shift initial individual choices.
