An experimental study about the role of the communication in an economic environment.

我进行了一个实验室实验，研究以下四种信息在独裁者游戏中的影响。O是关于接受者对独裁者的提议的规范性判断的信息。P是关于收款人期望收到的金额的信息。Q是关于接受者选择是否成为独裁者的提议的信息。R是关于其他独裁者提供的信息。实验结果表明，O、Q和R的主效应分别是显著的。此外，虽然P的主效应不显著，但P × Q互作效应显著。

I conducted a laboratory experiment to study the effects of the following four kinds of information in a dictator game. O is the information on a normative judgment of the recipient about the dictator's offer. P is the information on an amount of money that the recipient expects to receive. Q is the information on an offer that the recipient chose if he would be a dictator. R is the information on the offers of other dictators. The experimental result shows that main effects of O, Q, and R are significant, respectively. Moreover, although the main effect of P is not significant, the effect of P x Q interaction is significant.
