Abstract of the Paper:
When designing allocation rules for scarce goods or services, market designers often face the issue of balancing between efficiency and fairness. Critically, resolving this issue requires quantifying various forms of efficiency losses. We document that a previously understudied source of efficiency loss stemming from queuing can be substantial in many real-world booking systems using first-come-first-served allocation rules. We provide a novel experimental framework that allows us to quantify and compare different sources of efficiency losses across different allocation rules. The theory predicts and lab experiments confirm that the efficiency loss due to opportunity costs of time spent on queuing overwhelms any other efficiency concerns in a booking system based on queuing. However, such loss is almost completely eliminated in a booking system based on lotteries. We also develop and test a novel dual-track system that allows participants to freely choose their preferred allocation rule. We observe a majority prefers the allocation rule based on lotteries over the rule based on queuing.
