基于机会项目标价值分布的选择自由测度研究

Appraisal to Freedom of Choice Based on the Distribution of Objective Value of Opportunities

摘要: 基于机会项效用的选择自由测度没有对价值与效用的概念进行区分。机会项的价值与机会项的效用实际上是两个既有联系又有区别的概念。机会项的价值具有三种形式，即机会项的目标价值、机会项的非目标价值以及机会项的参与人价值。基于机会项的目标价值分布，文章提出一种新的机会集选择自由测度方法；利用广义洛伦茨曲线确定机会集选择自由测度指标的参数。

Abstract: The value and the utility of opportunity are distinct and related concepts. The value of opportunity has three forms, namely objective value, non-objective value and value to participant. Based on the distribution of objective value of opportunity, a news method of measuring freedom of choice is given and parameters in the model are determined by the generalized Lorenz curve.
