Features of antimonopoly regulation of the markets of basic and derivative goods

The markets of after-sales service and components occupy a dependent position in relation to the markets of the main product. Classic examples of this kind of dependence are: the car market and the service market, the MFP market and the cartridge market, the shaving machine market and the cassette market, the software product markets and their updates. In such cases, manufacturers of products in the so-called main markets can limit competition in derivative markets using dealer licensing or through the terms of a contract with the consumer within the framework of warranty service. The relevance of the study is also due to the emergence of new plots of anti–competitive actions and agreements (for example, restricting access to personal data of owners of primary market products – to Big Data of sensors of the car engine control system - limits the entry of participants into the after-sales service market of cars). In this context, the Internet of Things and the digitalization of production chains gives primary market participants the opportunity to control data flows and access conditions to them, which determines the exclusivity of access to derivative markets, associated with the risk of monopolization. The purpose of the study is to identify the sources of risks of limiting competition in the activities of companies in the markets of the main product and after-sales service (including consumables and components). The objectives of the study include: identification of sources of risks of violation of antimonopoly legislation in the markets of the main product and after-sales service; analysis of cases of international and Russian practice of antimonopoly regulation of the markets of the main product and after-sales service. The research methodology includes models of industry analysis of markets, quantitative methods of antimonopoly analysis, tools of a new institutional economic theory. The conclusions of the study contain characteristics of the markets of the main and derivative goods that are significant for the antimonopoly regulation of such markets, as well as a theoretical justification for the need to use refined methods of quantitative analysis for the purposes of antimonopoly enforcement, taking into account the specifics of the markets of the main and derivative goods.
