neofunctionalism

Neofunctionalism is a theory of regional integration which downplays globalisation and reintroduces territory into its governance. Neofunctionalism is often regarded as the first European integration theory developed by Ernst B. Haas in 1958 as part of his PhD research on the European Coal and Steel Community. Neofunctionalism seeks to explain the European integration process and why states accept to become a part of supranational organization. Jean Monnet's approach to European integration, which aimed at integrating individual sectors in hopes of achieving spillover effects to further the process of integration, is said to have followed the neofunctional school's tack.

Ernst B. Haas, later declared the theory of neofunctionalism obsolete, a statement he revoked in his final book, after the process of European integration started stalling in the 1960s, when Charles de Gaulle's "Empty Chair" politics paralyzed the institutions of the European Coal and Steel Community, European Economic Community, and European Atomic Energy Community. The theory was updated and further specified namely by Wayne Sandholtz, Alec Stone Sweet, and their collaborators in the 1990s and in the 2000s (references below). The main contributions of these authors was an employment of empiricism.
