This book highlights the changing face of social policy and social work against the background of accelerating transnationalization of economies, labour markets, education, social services, and care. The contributions of this book provide unique case examples on the interplay of social policies, mobile populations, and travelling knowledge about welfare within an increasingly asymmetrical global context. This innovative volume also includes historical studies on the transformations of social policies during the last century and reflects the developments of social welfare across the Global North and the Global South. With its emphasis on theoretical assumptions of policy translation, the case studies show the importance of adjustments, negotiations, and participation of various actors in the transnational social field of welfare production. Thus, within ever-shifting contexts of new political agendas promoting the free play of the market and a neoliberal agenda of competition and austerity, this insightful book reveals new transnational forms of social exclusion that function within, across, and in-between nation-states.
