Does Studying Economics Discourage Cooperation? Watch What We Do, Not What We Say or How We Play
通过“丢失信件”实验发现，经济学学生归还装有现金信封的比例显著高于其他学生，表明其实际合作行为更强，挑战了以往基于言论和游戏得出的结论。
Based on what economics students say and how they play games, economics students appear less cooperative than other students. But appearances can be deceiving: the evidence in this paper indicates that the actual behavior of economics students is more cooperative than that of other students. The authors carried out a ‘lost letter’ experiment, in which envelopes containing currency were dropped in classrooms and the return rate measured. In this test of actual behavior, the economics students returned a significantly larger percentage of lost letters, exhibiting more cooperative behavior than other students.
