This book provides new insights into how the concept of bricolage is used to foster research on social entrepreneurship.The contributors assess the relevance of the concept from a theoretical point of view, questioning the concept and its relationships with similar concepts or theories, like those of effectuation and improvisation; use the concept of bricolage to study processes by which social entrepreneurs make their business grow; and investigate the diversity of social entrepreneurial situations and, as a consequence, the variety of forms (and effects) of bricolage practices. The primary objective of this book is thus to shed light on bricolage in social entrepreneurship, especially at the intersection of different levels of analysis and in different contexts. It takes stock of existing research at the intersection of both concepts and looks at future research avenues. This book was originally published as a special issue of Entrepreneurship and Regional Development.
