Haas defined integration as “a process for the creation of political communities defined in institutional and attitudinal terms” (Haas, 1970, 610- 611). Among his generalizations for the regularities observed within the industrialized-pluralistic nations (such as the case of economic integration of Western Europe) were: (1) interests of the governments and groups in direction of interdependence and mutual benefits (2) collective decisions, (3) spill-over and (4) the faith of elites in increased integration.
