Dynamic Matching in Overloaded Waiting Lists
构建了一个模型，研究等候名单分配机制中等待时间的内生波动如何导致资源错配和福利损失，并提出随机分配政策可改善福利。
This paper introduces a stylized model to capture distinctive features of waiting list allocation mechanisms. First, agents choose among items with associated expected wait times. Waiting times serve a similar role to that of monetary prices in directing agents' choices and rationing items. Second, the expected wait for an item is endogenously determined and randomly fluctuates over time. We evaluate welfare under these endogenously determined waiting times and find that waiting time fluctuations lead to misallocation and welfare loss. A simple randomized assignment policy can reduce misallocation and increase welfare.
