This accessible introduction to the world economy and to the theory and practice of globalization argues that key topics in international economics cannot be understood without knowledge of international business, and vice versa. It reviews and combines insights from both literatures and applies them to real-world issues, clearly explaining the main concepts of international economics and business in a uniquely integrated approach. This accessible text contains numerous international examples and is a clear and comprehensive account of how nations and firms function in the modern era of global competition.
