This volume contains the papers presented at the annual Concurrences Journal conference held on 22 February 2013 at the French Parliament. After a key note paper from Commissionner Joaquin Almunia on the state of competition policy enforcement in the EU in 2013, the papers adress four main issues : • Opening competition in protected sectors: Should new entrants be protected? • Personal data: Will competition law collide with privacy? • Private enforcement: Will the wave be coming from Brussels, London, Paris or… elsewhere? • Industrial policy: Can a pro-competition industrial policy exist? The volume ends by a contribution of Fleur Pellerin on innovation and competition.
