中文摘要
摘要：Booking.com 等主导平台经常施加价格平价条款，以阻止替代销售渠道出现更低价格。我们利用 2015 年法国针对三大全球酒店集团取消上述价格限制这一事件，提供准实验证据。分析显示，对于通过消费者可见渠道（如酒店官网或在线旅行社）销售的客房，价格效应有限且不具统计显著性。然而，我们发现，在消费者不可见的销售渠道（如直接线下预订）上，价格出现显著下降。此外，我们还识别出预订份额从在线旅行社向酒店直接线下渠道的显著转移。
Abstract
Abstract Dominant platforms like Booking.com have often imposed Price Parity Clauses to prevent lower prices on alternative sales channels. We provide quasi-experimental evidence on the removal of these price restrictions in France in 2015 for three major global hotel groups. Our analysis reveals limited and non-significant price effects for rooms sold through consumer-visible channels, such as hotels’ websites or online travel agencies. However, we document a significant price reduction on sales channels not visible to consumers, such as direct offline bookings. Additionally, we identify a significant shift in the share of bookings from online travel agencies to the hotels’ direct offline channels.
