We examine the effects of quantity-based approaches to airport congestion management such as slot restrictions on price dispersion and on-time performance. From the evidence at Newark Liberty International Airport, we find that slot restrictions increase price dispersion and improve on-time performance. Price dispersion originates from heterogeneous price effects, as ticket prices for high-value passengers increase more than that for low-value passengers. Our novel finding is that the share of passengers who have purchased tickets at a top-end price increase despite the price hike. We use various empirical specifications and an analysis on leads and lags of the policy for robustness.

基于数量的拥堵管理的异质价格效应和价格分散性增加

我们研究了基于数量的方法对机场拥堵管理的影响，例如航班时刻限制对价格分散和准点率的影响。根据纽瓦克自由国际机场的证据，我们发现航班位限制增加了价格分散性，并提高了准点率。价格分散源于不同的价格效应，因为高价值乘客的机票价格涨幅高于低价值乘客的票价涨幅。我们的新发现是，尽管价格上涨，但仍以高端价格购买机票的乘客比例有所增加。我们使用各种经验规范和对稳健性政策的领先和滞后的分析。
