Although North American integration has been the topic of heated publi
c debate, it has not yet received adequate theoretical attention from
the field of international relations. This article reviews the movemen
t to codify North American integration, and explores the implications
for integration and international relations theory. The first section
reviews the intellectual history of integration theory as it developed
in the European context. The second considers the North American expe
rience of codifying integration, 1982-1994. The third part returns to
integration theory and international relations, offering some amendmen
ts and suggestions considering the North American experience. The arti
cle argues that the dearest understanding of regional integration in t
he 1990s can be achieved through an approach which stresses developmen
ts in the global political economy as catalysts for change, and looks
to national and transnational institutions and social forces to explai
n variations in integration projects. Because other international rela
tions theories such as neofunctionalism and interstate bargaining are
unable to integrate these levels of analysis, they offer an incomplete
view of present dynamics.
