This title was first published in 2001. This is a collection of papers that look at the structure of the global economy, and its changing paradigms over the years. The contributors look at how the classic concept of state - autonomous, sovereign and freed of all constraint - never really reflected the reality of the international scene, despite the role it has played in realist and neo-realist theory for many decades. Instead, they consider that the political, social and economic characteristics originally attributed to states seem increasingly to be expressed through regional constructs. The papers in this volume show that even within regionalism there are a variety of different models that exist, and examine five of those models: the European Union; Mercosul-Mercosur; the North American Free Trade Area (NAFTA); the Association of South East Asian Nations (ASEAN); and the South African Development Community (SADC).
