The emergence of new forms of platform economies, such as Uber, has disrupted the basis and context of regulation in taxi passenger services. This research project examines to what extent regulatory and legal context has shaped how Uber has become established in three cities: Helsinki, st Petersburg and London. We will interview experiences of drivers in each of the cities and will examine the overall operational context. We then look at regional and global context of regulation and how and on what basis lessons may be learned across countries. The aim of our research is to understand better the relationship between “uberisation” and national and local regulatory practices as well as to examine and analyse to what extent and how new platform economies could be used to enhance social protection in the informal sector. Furthermore we ask if and how new platform economies could – intendely or unintendedly – contribute to globalisation of social rights.
