The recognition of entrepreneurship as a solution to, rather than a cause of, environmental degradation and social inequality moved the field to identify a new type of entrepreneurial activity, namely sustainable entrepreneurship. Scholarly interest has spiked in recent years; however, aside from its aspirational appeal, there remains a lack of understanding of the nature of the phenomenon and the future of sustainable entrepreneurship in theory and practice. This review seeks to provide a conceptual basis for stimulating scholarly thought and improving our collective understanding of sustainable entrepreneurship as a distinct subdomain within entrepreneurship research. Based on boundary definition and delineation of main features, this review critically discusses the main challenges ahead and elaborates on the research implications and future research directions beyond current, dominant approaches to entrepreneurial action.

This paper examines the development process of sustainable ventures by focusing on three substantive markers, namely the ideas, actions, and exchange relationships articulated and instigated by the entrepreneurs in question. Based on data from 45 sustainability-oriented new ventures, it examines the causal configurations behind the manifestations of these markers using Fuzzy-Set Qualitative Comparison Analysis (fsQCA). The analysis also reveals two distinct opportunity development paths. The first, conformist, operates in an enabling supporting context as sustainability conveyor. The second, insurgent, path operates as a change agent against an establishment that is not conducive to sustainability ideals. ! THE CALL OF THE WHOLE IN UNDERSTANDING THE DEVELOPMENT OF SUSTAINABLE VENTURES

Sharing economy businesses have emerged in recent years as a disruptive approach to the traditional way of planning, modeling and doing business. The phenomenon has gained significant traction within a wide range of domains including entrepreneurship, innovation, technology and management more broadly. Despite this surge and interest, there is a lack of empirical research regarding the increasing diversity of sharing economy business models and the implications for business growth, community impact, sustainability and public policy. With this research, we sought to leverage a rigorous comparative method, fs/QCA, to assess the business models of 36 firms in the sharing economy. Leveraging a rich set of qualitative data, our analysis leveraged seven dimensions of sharing economy business models drawn from extant research, revealing a typology comprising five ideal types that collectively account for the constellation of possible, empirically-relevant business models across the sharing economy. The emergent dilemmas and paradoxes as well as implications of these typologies of business models for startups, investors and policymakers are explored. HighlightsSharing business modeling is complex yet the one-size model fits all logic prevails It seeks to understand the inner complexity and diversity of sharing business models Using fsQCA, it analyses 36 firms deriving a typology of 5 business models It enables a more fine-grained understanding of the sharing business space It reveals a number of paradoxes, challenges and opportunities for a range of actors ! *Highlights (for review)

ÒBuilding a sharing infrastructure and culture is quite simply one of the most important things cities can do to contribute to a fair and sustainable worldÓ (Agyemen, et al., 2013, p. 29). AbstractCalls for a transformation towards more sustainable consumption and production (SCP) have been intensifying. As urban populations swell across the planet, cities are faced with incresing pressure on infrastructure, economic and ecological systems. Yet, with their high population densities and ubiquity of information and communication technologies, cities are becoming breeding grounds for a new, circular economy driven by emerging and long-standing sharing activities. This research provides a comprehensive view of SCP systems in cities by integrating and examining sharing economy activities in the context of two continuums, i.e. SCP and private/public orientation. Based on these two analytical dimensions, the paper evaluates and plots five groups of 18 sharing activities to create a Sharing Cities-SCP Typology comprised by five ideal types. Each of these five types represents a unique form of SCP activity, with the potential to directly impact SCP systems in the context of urban environments. By enabling diversity and hybridity in the SCP analysis, we allow for a theoretical expansion of SCP models and a new way of understanding how they may play out in cities. Highlights¥ The paper examines the relationship between sharing economy activities and SCP in cities ¥ It analyzes several classification alternatives in light of substantive data ¥ It examines sharing activities in light of two continuums, i.e. SCP and private/public orientation ¥ It evaluates 18 activities to develop a Sharing Cities-SCP Typology comprised by five ideal types, each of them representing a unique form of SCP activity within the SCP system. ¥ In the context of sustainable business, we extend the notion of hybrid modeling by incorporating the consumption and production dimensions
