In this interview for the Global Governance Innovation Platform (GGI), Jean-Frédéric Morin distinguishes between invention and innovation in global governance. He describes inventions as new governance arrangements and innovations as those that are successfully applied and replicated, while noting that even isolated inventions can expand the policy toolbox and contribute to institutional diversity. He discusses the role of experimentation, feedback and replication in developing and adapting governance arrangements, and considers how new approaches can emerge by combining existing ideas and practices in novel ways.
