本文介绍了一个程式化的模型来捕捉显着特点的等候名单分配机制。首先，代理在具有相关联的预期等待时间的项目中进行选择。在引导代理人选择和配给物品方面，等待时间起到与货币价格类似的作用。第二，物品的预期等待时间是内在决定的，并随时间随机波动。我们评估这些内生决定的等待时间下的福利，发现等待时间的波动导致分配不当和福利损失。一个简单的随机分配政策可以减少分配不当，增加福利。(JEL C78、D61、D82、D83）
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. (JEL C78, D61, D82, D83)
