Over the last decade, the phenomenon called collaborative economy or sharing economy gained significant dimensions and crossed many sectors of economic and social life, creating new business models. Despite the growing interest, there is no single concept for its definition, manifestations, impacts and business models, while at the same time, digital platforms have allowed its sophisticated development. The seen emergence of sharing economy in Bulgaria brings out the need to study the phenomenon at the national level, its context, development, stakeholders. (...) The aim of this chapter is to shed light on the main manifestations and regulatory issues of the sharing economy in Bulgaria and to discuss its stage of development critically. The first part starts with a review of definition aspects and academic conceptualisation of the sharing economy and key issues. In the second part, aspects of the context and manifestations in the development of the phenomenon are discussed. Then, looking at several national examples of market players, an attempt is made to present the sectoral scope of the sharing economy and its development and to highlight the active stakeholders in the market. The study concludes with a discussion on the policies to be developed at the national level and future research to be carried out in order to catch the potential opportunities and overcome potential barriers.

One of the greatest achievements of modern physics is the discovery of spacetime by Hermann Minkowski. Still, talking about the ”discovery” of spacetime cannot be done without further questioning its ontological status. Did Minkowski discover a real physical substrate? What is the creative role of his scientific imagination in the process of discovery? To what extent the explanatory power of spacetime supports the conclusion that it is a true description of the physical world? I consider those questions in that paper, (...) and I claim that for Minkowski’s discovery of spacetime, imagination and explanation work together in a fictionalist strategy. I explain why there is no reason to doubt the veracity of the discovery of spacetime and its physical reality. (shrink)
