Illicit goods cross invisible and visible barriers of borders, social regulation and control, and societal norms using largely the same supply chain mechanisms and technologies employed by legitimate organizations. Illicit market participants evade and elude traditional control mechanisms, and, in some cases, capitalize upon systemic gaps or failures to deliver legal or illegal goods in prohibited environments or distribution channels. This paper facilitates an examination of the complexity and common elements of supply chains and organizational environments across functions and international boundaries, and articulates the link between illicit market activities and terrorist organization funding. Insights into constraints and operations of illegal and enforcement activities generate constructive theoretical and research directions for developing intervention and disruption strategies.
