Introduction The International Competition Network (ICN), a “virtual” organization comprised of most of the world’s competition (antitrust) agencies and expert non-governmental advisors (NGAs), held its Sixteenth Annual Conference in Porto, Portugal from May 10-12. (I attended this Conference as an NGA.) Now that the ICN has turned “sweet sixteen,” a stocktaking is appropriate. The ICN can point to some significant accomplishments, but faces major future challenges.
