In recent years, a tendency on the part of different authorities to consolidate has been noted worldwide. Competition agencies are merging with consumer protection agencies and/or regulators in order to establish more effective and less expensive public systems. Accordingly, since the first roundtable meeting on the optimal design of a competition agency, held in February 2003, OECD has organized two more roundtables concerning changes in the institutional design of competition authorities in less than one year – one in December 2014, and one in June 2015.
