This introduction presents an overview of key concepts discussed in the subsequent chapters of this book. The book explores three main questions: What factors cause transnational crime? How does the process of globalization affect such crime? How does globalization affect crime control efforts? It takes discusses the issue of intellectual property (IP) crimes, which the author constructs as a corporate externality in a way that parallels similar analyses of several other industries and their 'lawful, but awful' practices. The book addresses a problem that relates to all types of financial crime: trade-facilitated crime and the comparative inattention of authorities to the lack of transparency in cross-border commercial activities. Finally, it explores the ways in which legal and illegal transnational actors interface.
