In this paper, we describe what economists have learned about differences between group and individual decision-making. This literature is still young, and in this paper, we will mostly draw on experimental work (mainly in the laboratory) that has compared individual decision-making to group...

While most papers_new on team decision-making find teams to behave more selfish, less trusting and less altruistic than individuals, Cason and Mui (1997) report that teams are more altruistic than individuals in a dictator game. Using a within-subjects design we re-examine group polarization by...

We use a laboratory experiment to examine whether and to what extent other-regarding preferences (efficiency, inequality aversion and maximin concerns) of team managers influence their management style in choice under risk. We find that managers who prefer efficiency are more likely to exercise...

We use a laboratory experiment to examine whether and to what extent other-regarding preferences of team leaders influence their leadership style in choice under risk. We find that leaders who prefer efficiency or report high levels of selfishness are more likely to exercise an autocratic...

While most papers on team decision-making find that teams behave more selfishly, less trustingly and less altruistically than individuals, Cason and Mui (1997) report that teams are more altruistic than individuals in a dictator game. Using a within-subjects design we re-examine group...

We test for behavioral differences between groups and individuals in gift-exchange experiments. Related studies establish group behavior as typically closer to the game-theoretic equilibrium. We show that this result may depend crucially on the decision making procedure within groups. A novel...
