The Sharing Economy (SE) has been growing at an impressive rate across the globe (Cohen & Kietzmann, 2014) and emerging as an innovative and rapidly growing sector of the economy (Hira & Reilly, 2017), which attracted the attention of the scientific community. An increasing number of studies have been brought to light helping to document and analyze how SE manifests and evolves across economic systems, thus, contributing to refine and recast existing management theory (Mair & Reischauer, 2017). Nevertheless, there still is a lack of a common understanding of SE and its underlying mechanisms (Knote & Blohm, 2016). As an emergent category, SE has been contoured by being a mutant process, as it has been crafted by multiple and distinct temporal identity and legitimacy events, mechanisms and claims. Showing signs of being an on-going process of evolution, there is a constant need for further research to identify developments in the evolution of SE considering both identify claims (self-referential) and legitimacy (granted by stakeholders), which would offer additional comprehension about the SE phenomenon. The research addresses it by studying what is the role of SE in establishing the identity of organizations belonging to the field, considering both identify claims (self- referential) and legitimacy (granted by stakeholders)? To answer the research question, the research was designed involving two components inspired on category creation studies (Durand & Paolella, 2013; Glynn & Navis, 2013; Navis & Glynn, 2010; Kennedy & Fiss, 2013; Kennedy et al., 2010; Lounsbury & Rao, 2004; and Wry et al., 2014): 1) four prototypical SE organizations were selected, each of them belonging to Schor’s (2014) four SE archetypes of activities: (i) Airbnb – peer-to-peer, for-profit activity –, (ii) Zipcar – business-to-peer, for- profit activity –, (iii) TimeBanks – peer-to-peer, non-profit – and (iv) Make: makerspaces – business-to-peer, non-profit. The content of the evolution of their identity claims was analyzed, using data from their public available reports, as well as, other secondary data available on-line; and 2) considering the same set of SE organizations, legitimacy evolution was analyzed considering how scientific community, investors, customers, media, other analysts and other interested audiences have been constructing category meaning to them, conferring the formation of SE categorical and organizational identities, and perceptions about the viability of their business models (Tripsas, 2009, as cited in Navis & Glynn, 2010). In short, it was analyzed how stakeholders assess the viability of SE categories and organizations and can grant or withhold legitimacy to SE organizations (Zuckerman, 1999, as cited in Navis & Glynn, 2010). This research presents a new layer on framing a detailed understanding of the SE field in its maturing dimension, thus, meeting Mair’s and Reischauer’s (2017) call for studying the SE, unpack and make sense of an inspiring and complex phenomenon and thereby advancing and sophisticate the existing theory.
