International institutions and formal international organizations lie at the heart of the new global economy. International economic interactions occur within a framework of norms, rules and organizations, and an appreciation of this institutionalization is essential for understanding the functioning of the new global economy. The growth of the institutional framework has attracted extensive attention from political scientists, who in recent years have developed more nuanced theories of the international organizations' form, function and effects, and have begun to subject these theories to systematic empirical scrutiny. For this significant collection Lisa Martin has brought together the most important articles, published since 1982, on the role of institutions in the global economy and has provided a scholarly new introduction which gives a comprehensive overview of the subject.
