From the Lab to the Field: Cooperation among Fishermen
通过实地实验测量休闲渔民群体的合作程度，发现与实验室结果相反，当合作要求减少捕鱼努力时，个体不合作，并识别出活动类型是差异原因。
We conduct a field experiment to measure cooperation among groups of recreational fishermen at a privately owned fishing facility. Group earnings are greater when group members catch fewer fish. Consistent with classical economic theory, though in contrast to prior results from laboratory experiments, we find no cooperation. A series of additional treatments identifies causes of the difference. We rule out the subject pool and the laboratory setting as potential causes and identify the type of activity involved as the source of the lack of cooperation in our field experiment. When cooperation requires reducing fishing effort, individuals are not cooperative. © 2012 by The University of Chicago. All rights reserved.
