The development of short-term rental (STR) markets through digital platforms is transforming our habit (for example the way we rent a car or an apartment for our holidays) but also our neighborhoods and cities. The EU-funded DweLinks project explored the notions of "sharing" and "collaboration", the resources, as well as new, hybrid labour relations and conditions that are involved in STRs. Focusing on Athens and Berlin, DweLinks conducted an in-depth analysis of STR activities and their articulation within local sites and networks. Results of the project are expected to contribute to a better understanding how temporary and shared socio-economic practices and their digital organization are expressed in post-modern societies. DweLinks’ objective was to explore the qualitative, geographical, and space-transformative characteristics of platform economy, and its development within complex, multi-leveled assemblages, in Athens, Greece and Berlin, Germany. More specifically, the project investigated the ways the emergence and establishment of digitally mediated, short-term renting (STR) markets, take place through i) the mobilisation and ii) the creation of ties and flows, among a variety of actors and networks. DweLinks’ major research hypothesis is that the development and establishment of STR activities is taking place through assemblages that employ, bring together, and mobilize human, material, and symbolic elements: urban and natural resources and assets, labour, knowledge, services, historical meanings, and the notions of ‘sharing’ and ‘collaboration’. Through a qualitative methodology, heavily based upon assemblage thinking approaches, specifically Assemblage and Actor-Network Theories and the in-depth engagement with two study areas in each city, DweLinks i) analysed and delineated the STR markets’ landscape in Athens and Berlin, through the exploration of their networks and actors, extent and limits, hybrid development, practices, role in socio-spatial transformations and differentiations, ii) enriched and informed ‘platform economy’ literature in the fields of urban studies, and social and economic geography, iii) informed policy agendas and regulatory frameworks and formulate policy directions, through the in-depth understanding of the development of the STR activity and its articulation in local sites and networks.
