论文摘要
我们研究动态筛查问题，其中要素受到嘈杂的评估，并且在每个阶段，某些元素被拒绝，而其余的元素在随后的阶段被独立地重新评估。我们证明，ceteris paribus，动态筛选过程的质量在阶段的数量中不是单调的。具体而言，我们检查了公认的元素的值，并表明在筛选过程中添加一个阶段可能会产生较低的结果，而在随机优势方面，而增加阶段的数量大大导致了第一最好的结果。
We study dynamic screening problems where elements are subjected to noisy evaluations and, in every stage, some of the elements are rejected while the remaining ones are independently re-evaluated in subsequent stages. We prove that, ceteris paribus, the quality of a dynamic screening process is not monotonic in the number of stages. Specifically, we examine the accepted elements' values and show that adding a single stage to a screening process may produce inferior results, in terms of stochastic dominance, whereas increasing the number of stages substantially leads to a first-best outcome.
