This paper builds an economic model to investigate the interactions between baggage fee and airport congestion. With checked bag fees, we find that the socially optimal numbers of passengers and checked bags will not be achieved if the marginal congestion cost from carry-ons is larger than that from checked bags. However, it is possible with bundle pricing. Furthermore, we use numerical experiments to illustrate that checked bag pricing may underperform bundle pricing in terms of social welfare.

航空行李费和机场拥堵

本文建立了一个经济学模型来研究行李费和机场拥挤之间的相互作用。对于托运行李费用，我们发现，如果随身携带的边际拥堵成本大于托运行李的边际拥堵成本，将无法实现乘客和托运行李的社会最优数量。但是，捆绑定价是可能的。此外，我们使用数值实验来说明，就社会福利而言，托运行李定价可能不及捆绑定价。
