Abstract This paper elaborates on administrative sorting, a threat to internal validity that has been overlooked in the regression discontinuity (RD) literature. Variation in treatment assignment near the threshold may still not be as good as random even when individuals are unable to precisely manipulate the running variable. This can be the case when administrative procedures, beyond individuals’ control and knowledge, affect their position near the threshold non-randomly. If administrative sorting is not recognized it can be mistaken as manipulation, preventing fixing the running variable and leading to discarding viable RD research designs.

超越操纵：回归不连续性设计中的行政排序

摘要 本文详细阐述了行政排序，这是回归不连续性 (RD) 文献中忽略的对内部有效性的威胁。即使个体无法精确操纵运行变量，阈值附近的治疗分配变化可能仍然不如随机。当超出个人控制和知识的行政程序非随机地影响他们在阈值附近的位置时，就会出现这种情况。如果未识别出行政排序，则可能会被误认为是操纵，从而阻止修复运行变量并导致丢弃可行的 RD 研究设计。
