This paper studies the existence of two different supply operators in the peer-to-peer accommodation rental market for the city of Madrid. We specifically analyse spatial dependencies in price formation and whether the so-called professional hosts (i.e. those who have several Airbnb listings) set prices differently from single-property hosts. To this end, hedonic price models are estimated with and without spatial price dependence. Listings’ structural characteristics and accessibility measures to transportation hubs and sightseeing spots are considered in the regressions. Results provide clear evidence that price mimicking is higher among non-professional hosts whereas professional hosts set prices more independently.

本文研究了马德里市 P2P 住宿租赁市场中存在两个不同的供应商。我们专门分析了价格形成中的空间依赖性，以及所谓的专业房东（即拥有多个 Airbnb 房源的房东）制定的价格是否与单一物业的房东不同。为此，在有和没有空间价格依赖性的情况下估计享乐价格模型。回归中考虑了房源的结构特征和交通枢纽和旅游景点的可达性措施。结果提供了明确的证据，表明非专业主持人的价格模仿程度更高，而专业主持人更独立地设定价格。
