In the peer‐to‐peer market for tourist accommodation, the demand is oriented to the center of the cities, generating impacts in different areas, which has opened a social and political debate on their regulation. The regulatory response from public administrations has often been to limit the supply of existing accommodation. However, as proven by the case of Barcelona, this does not guarantee the decrease of demand, and instead, results in more intensive use of the available accommodation. Thus, this article presents an alternative proposal on the basis of a model on the concept of both contamination and public resources externalities.

规范游客住宿点对点市场的提案

在对等旅游住宿市场中，需求以城市中心为导向，在不同地区产生影响，这引发了有关其监管的社会和政治辩论。公共行政部门的监管反应通常是限制现有住房的供应。但是，正如巴塞罗那的情况所证明的那样，这不能保证需求的减少，相反，会导致对可用住宿的更多使用。因此，本文基于污染和公共资源外部性的概念模型，提出了另一种建议。
