<p>This open access book analyses the&nbsp;global diffusion of social policy as a process driven by multiplex ties between countries in global social networks. The contributions&nbsp;analyze links between countries via global trade<i>,</i> colonial history, similarity in culture, and spatial proximity. Networks are viewed as the structural backbone of the diffusion process, and&nbsp;diffusion is anlaysed via several subfields of social policy, in order to interrogate which network dimensions drive this process.&nbsp;</p>The focus is on a global perspective of social policy diffusion via networks, and it is the first book to explicitly follow this macro-quantitative perspective on diffusion at a global scale whilst also comparing different networks. The collection tests the network structures in terms of their relevance to the diffusion process in different subfields of social policy such as&nbsp;old age and survivor pensions, labor and labor markets, health and long-term care, education and training, and family and gender policy.<p></p><p>The book will therefore be invaluable to students and researchers of global social policy,&nbsp;sociology, political science, international relations, organization theory and economics.</p>
