MARKET CONCENTRATION AND INDUSTRIAL CONCENTRATION MEASURES IN THE SERVICE OF EFFECTIVE COMPETITION WITH SPECIAL REFERENCE TO THE TELECOMMUNICATIONS MARKET IN BIH

The problem of mergers and market concentration, especially the emergence of cartels, is becoming increasingly widespread throughout the world, and the importance of antitrust authorities is also becoming greater. It is very important to define the concept of "market dominance", which is the ability of a company or group of companies to continuously maintain high prices, significantly above long-term average costs, without significantly reducing sales due to high prices. Industry is constantly developing and is affected by various influences that lead to an increase in market concentration, and based on this, the paper points out that it is necessary to constantly analyze and monitor the movement of concentration in the leading branches of an economy, with special attention to be paid to the basic elements of industrial concentration on the basis of which it is possible to easily understand numerous and complicated processes of the economy and business. Accordingly, the subject of research in this paper is market concentration and models for measuring industrial concentration in the service of effective competition. In order to investigate the problem and the subject of research, a hypothesis was set that the telecommunications market in Bosnia and Herzegovina is highly concentrated. The following methods and techniques of scientific research were used in the paper: comparative method, inductive and deductive method, standard statistical methods, concentration indices. Based on the achieved research results, it was concluded that the telecommunications market in Bosnia and Herzegovina is highly concentrated.
