In the cosmopolitan democracy model, decisions are made by those affected, avoiding a single hierarchical form of authority. According to the nature of the issues at stake, democratic practice should be reinvented to take into account the will of stakeholders. This can be done either through direct participation or through elected representatives. The model advocated by cosmopolitan democrats is confederal and decentralized—global governance without world government—unlike those models of global governance supported by classic World Federalism thinkers, such as Albert Einstein.
