题目：The significant effect of uninformative signal on social preference

地点：弘远楼3楼311室

内容提要：

Information about the recipient affect people's giving behaviors. However little is known about how givers respond to uninformative signals, that is, signals that do not really tell us about the recipient's type. In our experiment, we use a mini-dictator game to generate such signals, in which the recipient allocates 0.5CNY either to herself or to another person. We then investigate how a third person, the giver, respond to such signals. Interestingly, We find that givers give significantly less to the recipient when she takes the 0.5 Yuan, but not give more when she gives it to the other person. This effect can be largely explained by changes in givers' belief about the recipient.

关于接受者的信息会影响人们的捐赠行为。然而，人们对捐赠者如何回应无信息的信号知之甚少，也就是说，那些没有真正告诉我们接受者的类型的信号。在我们的实验中，我们使用了一个小型的独裁者游戏来产生这样的信号，在这个游戏中，接受者将0.5元人民币分配给自己或另一个人。然后，我们调查了第三人，即捐赠者，是如何对这种信号做出反应的。有趣的是，我们发现，当接受者拿走0.5元时，给予者给的钱明显减少，但当她把钱给其他人时，却没有给予更多。这种影响在很大程度上可以用捐赠者对接受者的信念变化来解释。
