This book questions whether the recently promoted European 'social investment' strategy is able to regenerate the welfare state, promote social inclusion, create more and better jobs, and help address the challenges posed by the economic crisis, globalisation, ageing and climate change. To assess the diversity, achievements, shortcomings and potentials of social investment policies, it brings together some of the best social policy scholars and well-known policy experts, connecting academic and policy debates around the future of the welfare state. Supported by the Nordic Center of Excellence NordWel and the EU funded Network of Excellence RECWOWE (Reconciling Work and Welfare).
