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 Ph.D. 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.
Today, neofunctionalism is one of the best-known theories of European integration. In the last decades Haas' theory has been revived by several authors, who describe the neofunctionalist theoretical legacy left by him as able to speak directly to current EU studies and comparative regionalism, if it is seen as a dynamic theory that corresponds to established social scientific norms with disciplinary openness.
Neofunctionalism describes and explains the process of regional integration with reference to how three causal factors interact:
Early neofunctionalist theory assumed a decline in importance of nationalism and the nation-state; it predicted that, gradually, elected officials, interest groups, and large commercial interests within states would see it in their interests to pursue welfarist objectives best satisfied by the political and market integration at a higher, supranational level. Haas theorized three mechanisms that he thought would drive the integration forward: positive spillover, the transfer of domestic allegiances and technocratic automaticity.
Neofunctionalism was modified and updated in two important books that helped to revive the study of European integration: European Integration and Supranational Governance (1998) by Wayne Sandholtz and Alec Stone Sweet, and The Institutionalization of Europe (2001) by Sandholtz, Stone Sweet, and Neil Fligstein. Sandholtz and Stone Sweet describe and assess the evolution of Neofunctionalist theory and empirical research in their 2009 paper, Neo-functionalism and Supranational Governance.
Despite its profound insights in regional integration, neofunctionalism is widely criticized at an empirical level for failing to account the reality of the European Communities. Neofunctionalism predicts a progressive political integration, but such a development did not occur in the 1970s. The absence or the slow pace of regional integration in Western Europe throughout the 1970s and early 1980s has been the focus of the critique. The French boycott of the European institutions in the mid-1960s, led by then French President Charles de Gaulle's "Empty Chair" policy, had led to recognize the importance of political leaders as constraints on the integration process. The neofunctionalists have acknowledged that "de Gaulle has proved us wrong".
Haas also talked about "spillback", a disintegrative equivalent to spillover. Brexit can be regarded as an example of spillback process in the EU. Neofunctionalist framework does not predict that a major country chooses to leave the EU. However, neofunctionalism scholars may argue that spillback processes are often followed by spillovers, that crises are opportunities to further integrate in the long run. As Jean Monnet famously puts in his memoirs, "Europe will be forged in crises and will be the sum of the solutions adopted for those crises".
On theoretical grounds, Intergovernmentalism is a theory on European integration which rejects the neofunctionalist mechanisms of integration. Intergovernmentalism is an alternative theory of political integration that also aims to explain the integration process, where power in international organizations is possessed by the member-states and decisions are made unanimously. Independent appointees of the governments or elected representatives have solely advisory or implementational functions. Intergovernmentalism is used by most international organizations today. An alternative method of decision-making in international organizations is supranationalism.
The theory, initially proposed by Stanley Hoffmann (classical intergovernmentalism) and refined by Andrew Moravcsik (liberal intergovernmentalism) suggests that governments control the level and speed of European integration. Any increase in power at supranational level, Moravcsik argues, results from a direct decision by governments who make decisions based on a domestic agenda. The theory rejects the spillover-effect argument and the idea that supranational organisations wield political influence on par with that of national governments.
Neofunctionalists have criticized intergovernmentalism on theoretical grounds as well as on the basis of empirical evidence, which they claim demonstrates that intergovernmentalism is incapable of explaining the dynamics and trajectory of European integration.
