Abstract:
The junction of economy, law and technology is an important topic in the world that is increasingly
moving online. Digital platforms “match” supply and demand by using large amounts of
data and algorithms. Some digital platforms dominate travel markets because of platforms’ data and
networks effects. Digital platforms in travel industry use algorithms to generate suggestions to consumers
via recommendation (ranking) systems. Ranking has important implications not only for business
users of digital platforms, but for consumers’ choice as well. This research explores motivations to
participate in digital platforms for short-term vacation rental and it sheds light on information asymmetries
in regard to algorithms generating ranking in search results. This research also briefly explores
EU regulatory approach to digital platforms and looks at the latest EU legal texts in regard to
fairness and transparency in ranking.
Keywords:
Fairness, Ranking, EU Regulation, Algorithm.
