In this new paper, Geoff Mulgan, Chief Executive of Nesta, summarises some of the key policy tools that national governments have used or considered, and which together provide a menu of options for any future national governments that want to develop a more comprehensive strategy for social innovation. The tools are divided in ten categories: Laws and Regulations, New Funding Sources, New Uses of Money, Social Innovation and Public Services, Growing Capacity, Empowerment and Democracy, Social Innovation and Science R&D, Social Innovation and Problem Solving, New Metrics, and Structures.
