The book develops an integrated approach of competition policy analysis. Based on the assumption that the deterrence of anticompetitive behaviour is the fundamental aim of competition policy rules and their enforcement, three pivotal levels of such an integrated approach are identified: a fundamental level, a strategic level as well as an operational level. Subsequent to the development of the approach, it is applied to three traditional areas of competition policy – hard core cartels, horizontal mergers and predation – before conclusions are drawn on how to ameliorate current competition policy.
