摘要
研究理性选择函数描述方式的等价性问题。首先定义选择函数并给出理性选择函数的形式化描述。定义选择函数的展示偏好和一致性条件,并对展示偏好与一致性条件间的关系进行分析。在此基础上,探讨理性选择函数的展示偏好描述和一致性条件描述的相互关系,得到了3种理性选择函数在两种描述方式上达到一致的条件。所得结论表明,理性选择函数的展示偏好描述和一致性条件描述具有等价性。
In this paper the description forms for rational choice functions are studied. First, the definition of choice function is given and the normative forms of rational choice function are defined. Then the definitions of revealed preference and consistency condition of choice function are given, and the characteristics of the revealed preference and consistency condition are investigated. On this basis, the relation between the revealed preference description form and the consistency condition description form is studied, and the conditions under which the two description forms of rational choice function can coincide are presented. The result shows that under certain conditions, rational choice function's revealed preference description is equivalent to its consistency condition description.
