Аннотация:Social enterprise is a broad and diverse set of phenomena that has emerged in recent decades to address a variety of social issues and problems not sufficiently addressed by traditional governmental, nonprofit or private sector solutions. As such it can be initially understood by extending market failure theory past its current three-sector focus of market, government and voluntary failure into the remaining areas of social concern not sufficiently well served by the three traditional sectors. However, social enterprise does not easily fit the "sector" model; indeed its diversity and complexity require a more embracing conceptual frame of reference. Hence we employ the metaphor of the social enterprise zoo to help define the boundaries and composition of social enterprise. Using this perspective, this book examines the concepts and content of the social enterprise zoo, how the zoo functions as an interactive collection of diverse animals in various habitats, how the zoo is managed and governed by its curators and zookeepers, and how we can assess the performance of the social enterprise zoo in terms of innovation, economic resilience, and overall social impact.
