Preface
Beware of a thick book.-RicHARD wagner
This book is intended for conventional undergraduate courses in interna-tional economics of either one or two semesters in length. The full line of usual topics is included, and the discussion is almost entirely verbal and geometric. More advanced or specialized material is provided by starred sections labeled EXPLORING FURTHER. These sections contain no algebra or advanced mathematics, but do on occasion make intensive use of geometry. They can all be skipped without loss of continuity. The mathe-matically trained student is directed to Appendix I, which provides a tech-nical treatment of international trade theory, keyed to Part One of the text. A typical one-semester course would cover the unstarred sections of the core chapters (1-4, 8, and 9) together with whatever the instructor wishes from other chapters. A one-year course might cover the entire text and supple-ment it with readings. Appendix I is suitable for graduate students and more sophisticated undergraduates.
The majority of sections are followed by a selection of problems. The problems are arranged more or less in order of increasing difficulty, and especially challenging problems are distinguished by asterisks. Students should at least attempt the unstarred problems before going on to the next section. Appendix III provides the answers to a selection of problems.
