Book excerpt: The formation of "multinational" and "transnational" companies, coupled with the accelerating pace of technology, has changed the way the world practices business. International Business and Trade: Theory, Practice, and Policy addresses the challenges that face large, worldwide businesses today and in the 21st century. This textbook introduces business executives and students to current issues and practices in international business. It analyzes the conceptual nature and operational aspects of multinational enterprise and international trade practices. The book is divided into three parts, each addressing a specific area of international business. The first part discusses the theoretical framework of global commerce, monetary systems, and financial environments. The specifics of international business operations-from legal environments to international trade and foreign investments-are covered in Part II. Part III concentrates on government policies and practices, covering the role of national and international organizations in impacting trade and investments.
