Buccirossi, Paolo; Ciari, Lorenzo; Duso, Tomaso; Spagnolo, Giancarlo; Vitale, Cristiana (Oktober 2009): Measuring the deterrence properties of competition policy: the Competition Policy Indexes. SFB/TR 15 Discussion Paper No. 284




The aim of this paper is to describe in detail a set of newly developed indicators of the quality of competition policy, Competition Policy Indexes, or CPIs. The CPIs measure the deterrence properties of a competition policy in a jurisdiction, where for competition policy we mean the antitrust legislation, including the merger control provisions, and its enforcement. The CPIs incorporate data on how the key features of a competition policy regime score against a benchmark of generally-agreed best practices and summarise them so as to allow cross-country and cross-time comparisons. The CPIs have been calculated for a sample of 13 OECD jurisdictions over the period 1995-2005.
