The book includes considerable amounts of data, especially in this chapter. Students should be encouraged to peruse this data-perhaps by challenging them to discover "interesting facts" or by giving them an international trade IQ test-including questions such as which country is the world's largest exporter, etc. The chapter previews the Heckscher-Ohlin theory of trade flows in its discussion ofU.S.-Japan trade patterns. Students could be prompted to search through the tables for other examples of trade patterns that have similar regularities to them. In urging students to look for and to attempt to explain these patterns, one is laying a solid foundation for the theoretical work that will be developed in the chapters to come.
