The De Gruyter Handbook of Social Entrepreneurship serves as a one-stop shop for nascent and established scholars and practitioners alike who seek to quickly gain a broad familiarity with the current state of research in social entrepreneurship. Part 1 reviews and discusses the historical scholarly foundations of the field, followed by a more in-depth treatment of newer research, while Part 2 examines the broader ecosystem in which social entrepreneurship takes place. In Part 3, the handbook explores infrastructural considerations such as organizational culture, values, processes, business models and mindsets that affect social entrepreneurship. Finally, in Part 4 the handbook analyzes social entrepreneurship from the individual social entrepreneur’s perspective. Faculty, research-oriented graduate students, think tanks, and government agencies who seek an overview of recent research in the field of social entrepreneurship will benefit from this essential addition to the literature. In addition, practicing social entrepreneurs, intrapreneurs in corporate settings, and non-governmental organizations interested in social entrepreneurship can use this handbook as a resource to inform their approaches to the development of social ventures, how they support social entrepreneurs, and the ways in which they can foster conditions to support a thriving social entrepreneurial ecosystem.
