Addressing the economic aspects of ties between the United States and Mexico, this book looks at the structural characteristics of the border region and the flow of goods, services, capital, and people between the two countries. The contributors describe the cultural, economic, and demographic dimensions of the borderlands and focus on specific issues critical to the region, among them environmental pollution, migration, territorial issues, and the implications of borderzone industrial growth. Finally, the authors consider how these issues affect the national economies and relations between the two countries.
