Since the 1970s, we have witnessed a growing body of scholarship that investigates the social context, processes, and consequences of entrepreneurship. Despite—or, perhaps, because of—the conceptual vagueness around the definition of the entrepreneur, this topic has attracted attention from a wide range of interdisciplinary scholars and has been applied to a variety of entrepreneurial activities among businesses, nonprofits, social movements, and public sector initiatives. This review begins with three views of entrepreneurs that are rooted in classical scholarship, conceptualizing them as innovators, autonomy seekers, and organizers. It then analyzes the mechanisms that link these views to entrepreneurial outcomes at different levels of analysis. Scholarship on social networks examines how the structure of relations may transmit new ideas, encourage freedom from interpersonal constraint, and produce social support for organizing. Research on career structures considers how past organizational contexts tend to augment or decrease entrepreneurial propensities. Studies of organizational populations and regions address when the ecology of those contexts allows entrepreneurs to carve out a new niche, despite competition from incumbents. The review concludes with suggestions for improving research methodology and the representativeness of social contexts in the study of entrepreneurship.
