This volume contains papers presented at the 17th Annual EU Competition Law and Policy Workshop, organized by Philip Lowe and Mel Marquis and held at the European University Institute on 13-14 July 2012. From a variety of angles the book explores the themes of competition, regulation and certain public policies; their interactions; and, in some cases, their mutual tensions. The authors of the various chapters consider legal and economic issues relating to network industries, industrial, environmental and trade policies, and intellectual property and innovation policies, among others. Comparative views and the views of judges from different jurisdictions are provided, and techniques for mediating among different policy objectives and frameworks are discussed. Authors contributing to this book include: Rafael Allendesalazar, Robert D Anderson, Marco Boccaccio, Ginevra Bruzzone, Cristina Caffarra, Alexandre de Streel, Ian Forrester, Douglas Ginsburg, Geert Goeteyn, Calvin Goldman, Daniel Haar, Kullike Jurimae, Suzanne Kingston, Lars Kjolbye, Paul Lugard, Mel Marquis, Veljko Milutinovic, Giorgio Monti, Anna Caroline Muller, Rosa Perna, Anthony Pygram, Philip Lowe, Pierre Regibeau and Jon Stern.
