Main interests 
Haas was mainly interested in international integration. Haas realized that traditional European politics could be dramatically changed by liberalizing movement of goods capital, and persons, but his analysis differed significantly from classical liberalism.
He is the founder of neofunctionalism as an approach to the study of integration. Neofunctionalism recognizes the importance of national states but also stresses the roles of regional interest groups and the bureaucracy of regional organizations. Though the member states create the initial conditions, regional interest groups and international bureaucrats push the process forward, and national governments increasingly solve conflicts of interest by conferring more authority on the regional organizations, and citizens increasingly look to the regional organization for solutions to their problems.
Haas published numerous books, monographs and articles.
