In one of its previous books, the EMES European Research Network traced the most significant developments in 'social entrepreneurship' emerging inside the third sector in Europe. Building upon that seminal work, this volume presents the results of an extensive research project carried out over a four-year period of a comparative analysis of 160 social enterprises across eleven EU countries. It breaks new ground in both its articulation of multidisciplinary theoretical frameworks and its rigorous analysis of empirical evidence based on a homogenized data collection methodology. Looking at work intergration, it is structured around a number of key themes (multiple goals and multiple stakeholders, multiple resources, trajectories of workers, public policies) developed through a transversal European analysis, and is illustrated with short country experiences that reflect the diversity of welfare models across Europe. With contributions from an impressive list of academics, all members of the EMES European Research Network, this rich follow-up volume to The Emergence of Social Enterprise is essential reading for academics, researchers and students in the fields of the third sector and social policies.
