In this study, the differences in behavior and thinking between groups and individuals are examined in multiple ways using the methods of economics experiments. We found that: (1) the information used when adjusting behavior over time is different between groups and individual, (2) the cooperation rate of groups in the social dilemma situation is lower, which is largely influenced by the social value orientation of the group members, and the deeper understanding of the strategic situation they are facing, and (3) groups disguise lying better than individuals.

This study examined the preference changes of individuals through forming a group using experimental methods. It became clear that by becoming a group, people would like more selfish choices and risk averse choices. We also found that the determinants of group time preference tend to reflect the influence of those who emphasize short-term benefits more than those who emphasize long-term benefits. From experiments using a task (preemptive attack game) wherein participants consider whether or not to make defensive preemptive attacks from fear that an opponent may attack, it became clear that preemptive attacks from a group to an individual was higher than the other conditions.

We provide a game theoretical framework to explain how bottom punishment or top reward enhances performance of teams when there is heterogeneity across players in cost-performance relationships. We derive easy-to-check sufficient conditions to judge whether reward or punishment is better. From the sufficient condition, we know that punishment is better for less heterogeneous people and reward is better for more heterogeneous people if the performance function is additive. To check the theoretical predictions, we conducted the field and laboratory experiments. We found that while the reactions of the actual people to the two incentives are more complex than the predicted behavior by the theory, how they use sticks or carrots are consistent with the theoretical predictions.

The essence of the problem we encounter today, such as regional conflict and destruction of environment, is adjustment between persons involved on interests and actions, which is typically done through the negotiation. This research project investigate experimentally how people negotiate in the group, and what they choose. In the preemptive strike game, which is developed in social psychology, groups became more aggressive against individuals. In two-person zero-sum game, groups behave more consistent with Nash equilibrium prediction than do individuals.

Okano (2013) examined the decision makings between groups and individuals who play O’Neill’s (1987) game which is the game with win and loss, and found that the group decision making is more consistent with Nash equilibrium prediction. This indicates that Nash equilibrium has predictive power for the behavior of groups (This research was published in Games and Economic Behavior). By examining the various games, the experiments revealed that the positive synergies in group decision makings do not always occur. Furthermore, I studied theoretical analysis concerning the bargaining process within a group.
