The means of communication has long served to connect millions of people, living in the territories divided by the huge distances. One can easily consider them as the first manifestation of the globalization processes. The methods of communication constantly improved and diversified – from messengers and postal workers, through telegraph, radio and landline phones to the mobile and satellite communication, VoIP (Skupe, Viber & other), Instagram, Telegram (messenger) etc. The telecommunication industry is rapidly developing throughout the world (Jerbashian, 2015), and Russia is no exception. However, the global economic crisis of 2008-2009 considerably influenced this industry too. The credit risks that the telecommunication companies of Russia had faced in 2006-2007, before the global crisis, caused significant changes within the structure of the Russian mobile service market. (Dengov & Tulyakova, 2015). Where initially there had been several dozen mobile operators, defining the nature of the market as a monopolistic competition, within but a few years all the key positions there were taken by four major companies (domestic MTS, Megafon, Beeline and the Swedish company Tele-2), keeping out any new operators. In the two new articles on this topic, the authors address the analysis of the pricing strategies of the major operators within the Russian telecommunication market. In the first article, they calculated the concentration indices of the industry. Their values lead the authors to the conclusion about the “diluted” oligopoly that has fully emerged by now in the mobile communication market. As the result of their research, the authors came to certain conclusions about the character of the pricing policies of the main mobile operators in the Russian Federation and the strategies that they implement in view of price differentiation within the different regions.
