The idea of confining the idea of ‘rationality’ with that of the ‘choice of best elements’ unnecessarily limits the sense and scope of ‘rationality’. The existing internal consistency conditions that are popularly used in the social choice theory to assess a choice function are insufficient to analyse several choice patterns. The paper tries to address that problem by accepting a broader definition of rationality and characterizes choice behaviours where an individual chooses a k-th best element from set of alternatives, where k is an integer.

全域第 k 个最佳元素合理化选择函数的表征

将“合理性”的概念与“最佳元素的选择”的概念相限制的想法不必要地限制了“合理性”的含义和范围。社会选择理论中普遍使用的现有内部一致性条件来评估选择函数不足以分析多种选择模式。本文试图通过接受更广泛的理性定义来解决这个问题，并描述个体从一组备选方案中选择第k个最佳元素的选择行为，其中k是整数。
