Poorly designed waiting lists can be inefficient and unfair.
How to Allocate Subsidized Housing More EfficientlyTo study waiting-lists as allocation mechanisms, we analyze a class of waiting-list mechanisms where agents are offered a choice among items with corresponding expected waiting times. Because the expected waiting time required for a given item fluctuates over time, different agents may face different waiting times, potentially resulting in misallocation of items. In a stylized model we derive expressions for welfare and compare mechanisms. We find that a simple randomized assignment policy can decrease expected wait fluctuations, thereby reducing misallocation and increasing welfare.
