Эффекты распространения рыночной власти владельцев ключевых мощностей на рынках программного обеспечения
The article assesses the policies instituted by producers of operating systems, when they aim to boost sales of applied software integrated into their operating systems. It analyses the policies through the prism of the effects they exert on other participants of the markets for operating systems and applied software. To perform the analysis, the authors address the case of the antivirus software markets. This was due to the recent release of Windows Defender (a new anti-malware program developed by Microsoft and integrated in the operating system) and a simultaneous tightening of Microsoft’s policy towards other antivirus software companies. The paper regards Microsoft Corporation as a possible dominating company in the software market. The analysis of the situation in the sphere of operating systems and antivirus software illustrates that Microsoft’s actions can cause the scenarios with adverse consequences for public welfare in both static and dynamic aspects to unfold.
