The major goals of this revision have been to streamline the text and to present more student oriented examples. We are also providing a new design with enhanced four colour graphics. Much fine tuning and trimming has gone into almost every chapter resulting in a more approachable textbook for your students. Several chapters that are rarely used will now appear on the book's website. The 9th edition will be much better integrated with the book's website where students can get additional information and/or current events associated with many major topics in the text. Also, the website will have "Want to see the Math Notes" for those instructors that choose a more sophisticated math treatment of the major topics in both Micro and Macro. Another commitment to Instructor Support will be the annual updating of time sensitive PowerPoint slides.
