Abstract
This is an ethnographic and theoretical exploration of the `shadows': vast transnational networks of goods, services, people and exchanges that flow outside formal and legal state channels and international laws. These networks involve millions of people and more than a trillion dollars yearly worldwide, and my research demonstrates these are more formalized, integrated and rule-bound than traditional studies have suggested. Thus, `shadow' networks broker political, economic and social power that can rival many of the world's states, and they are profoundly implicated in world markets. This article explores core characteristics and cultures defining extant extra-state systems, and the power and potentialities for social sovereignty they wield. Investigation into shadow realities prompts a reassessment of the basic theoretical ideas concerning the nexus of legality/illegality, state/non-state and formal/non-formal power relations defining the world today.
