This article analyses the effect of different entry regulations on company conduct and traveller behaviour. The paper presents a comprehensive case study of three railway markets with significantly different entry policies using data on prices and frequencies together with a survey conducted to obtain revealed preferences. The study employs data from the three main lines in the Czech Republic. The two open access markets tended to provide significantly higher connection frequencies than the line with regulated entry did. Surprisingly, low price variation across the rail and bus markets suggests low monopoly power for the monopolised incumbent and its uniform price strategy across markets with different entry regulations. On the other hand, high price sensitivity among travellers confirms the importance of intramodal competition.

本文分析了不同入境规定对公司行为和旅客行为的影响。本文使用价格和频率数据以及为获得显性偏好而进行的调查，对进入政策截然不同的三个铁路市场进行了综合案例研究。该研究使用了捷克共和国三个主要线路的数据。与受管制进入的线路相比，这两个开放式准入市场往往提供明显更高的连接频率。令人惊讶的是，铁路和公共汽车市场的低价格变化表明垄断的现任者的垄断能力较低，并且其在不同进入法规的市场中采用统一的价格策略。另一方面，旅行者对价格的高度敏感性证实了模式内竞争的重要性。
