信号模型问题的扩展研究

信号模型提出了解决信息不对称问题的一种基本思路,但是,关于接收者如何考察信号,发送者的信号如何被传递的和发送者的信号成本构成等方面没有提供更加详尽的理论阐述。笔者试图对信号传递模型中的这3个问题进行些扩展研究,指出了信号的选择是发送和接收双方共同选择的结果,信号的传递过程类似双向沟通过程,信号成本包括信号制造成本、信号传送成本和信号考察成本。

Expansion Study on Signaling Model

Signaling model offers a basic instrument to account for the unbalanced issue on information,however,it does not expound theoretically in details about how receivers check the signal they received,how the signal from senders can be transferred and about the construct of signal costs of the senders,etc.In some aspects the three issues mentioned above of signal-transferring model are extended and analyzed.It is put forward that the choice on signal is the result of the common choice of senders and receivers;the transference of signal resembles the course of two-way communications;signal costs consist of the cost of making,transferring and checking the signal.
