论文摘要
我们考虑至少两种替代方案中最多两种的非操纵社会选择功能的类别。我们为我们考虑的每个类别提供功能形式。 这种功能形式是一种特征，明确描述了该特定类别的社会选择功能如何选择与配置文件相对应的集体选择。 我们使用新的“角色”概念提供了这些特征的统一表述。角色的选择取决于社会选择功能的类别，赋予了班级所有社会选择功能的功能形式。
We consider classes of non-manipulable social choice functions with range of cardinality at most two within a set of at least two alternatives. We provide the functional form for each of the classes we consider. This functional form is a characterization that explicitly describes how a social choice function of that particular class selects the collective choice corresponding to a profile. We provide a unified formulation of these characterizations using the new concept of "character". The choice of the character, depending on the class of social choice functions, gives the functional form of all social choice functions of the class.
