This Autumn 2009 issue marks several anniversaries; it is the tenth volume of CPI, the end of our fifth year, and the last issue we will publish in the first decade of the 21st century. Since our first issue, we’ve published 134 articles from many of the leading thinkers, doers, and judges of antitrust from around the world. As the global competition policy community has grown, so has this publication. Over the course of the year the CPI website attracts visitors from more than 150 countries. We extend our thanks to this vibrant community.
