对"经济人"假设的反思

“经济人”假设是新古典主义经济学对经济个体行为动机的最基本假设。它被认为是一种简单而有价值的经济学智慧。但现实生活中也有大量现象无法用“经济人”假设来解释。为了加强该假设的解释力,经济学家不断拓宽和发展其中心概念的含义,但这样做的一个不利后果是基本概念就往往变得过于宽泛和模糊,从而失去可操作性。

In order to enlarge its explanation, the economists try to develop the meaning of the definition, but at the same time such work makes the basic principles, like utility and rationality, even loose its applicability.
