Welcome to the ninth edition of Microeconomics, North America’s best-selling economics textbook. More than 7 million Canadian and U. S. students have now used this book. It has been adapted into Australian, Italian, Russian, and Chinese editions, and translated into French, Spanish, and other languages. We thoroughly revised, polished, and updated this edition. To use a software analogy, this is version 9.0, not 8.1 or 8.2. The comments of reviewers and survey correspondents provided encouragement, motivated improvements, and sparked innovation. Streamlined Presentations Amajor revision goal was to streamline presentations, where possible, without compromising the thoroughness of our explanations.Our efforts resulted in a more efficient organization and greater clarity. An example is Chapter 4, “An Overview of the Market System and the Canadian economy,” which is both shorter and better organized than before.
You will find similar kinds of improvements throughout the ninth edition.Where needed, of course, the “extra sentence of explanation” remains a distinguishing characteristic of Microeconomics. Brevity at the expense of clarity is a false economy. Improved Content The Ten Key Concepts, which appeared in the eighth edition, have been reinforced with margin icons when they are discussed later in the text.
