We study empirically the price dynamics in the long-distance bus market using posted fares by Flixbus, the market leader in Europe. We find that, at a given point in time, the fare increases with the number of sold seats. This result largely explains, why the lowest available fare increases as the departure date approaches. No evidence is found in favor of intertemporal price discrimination, probably because of low consumer-heterogeneity throughout the entire booking period that characterizes the long-distance bus market.

欧洲长途巴士服务的定价：以Flixbus为例

我们使用欧洲市场领导者Flixbus公布的票价，对长途巴士市场的价格动态进行经验研究。我们发现，在给定的时间点，票价会随着售出座位的数量而增加。这个结果在很大程度上解释了为什么最低的可用票价会随着出发日期的临近而增加。没有发现支持跨期价格歧视的证据，这可能是由于在整个长途客车市场的整个预订期内，消费者的异质性较低。
