The Damage Caused by Anticompetitive Practices. Effective Methods and Techniques of Quantification

Analyzing the impact of competition policy, the effects of anti-competitive practices and the decisions of competition authorities is a constant concern. Thus, public authorities, and especially competition authorities seek to justify the use of public resources to promote competition policy. Business representatives and international bodies seek to standardize competition rules so that they do not harm business development and others. In this regard, there are several methods and techniques applied to quantify the harm caused by anti-competitive practices, the economic effects of competition policy and the intervention of competition authorities proposed by the European Commission, the OECD, competition authorities in several countries, and the academic environment. The efficient analysis and quantification of the impact of anti-competitive practices are crucial in the regulatory process, being the premise of making the right decisions. The paper presents the classification and application of assessing methods for anti-competitive practices to determine the damage caused by them.
