    "description": "<p>Research questions: (1) How can we explain the development of monopolies<br />\non SNS markets? (2) Are monopolies possibly temporarily limited? (3) What<br />\ndoes this mean for competition (or antitrust) law?<br />\nResults: (1) Direct network effects (number of users) and indirect network<br />\neffects (complementary products and advertising) facilitate the development<br />\nof one standard und thus a quasi-monopoly. There is empirical evidence that<br />\nthere are indeed standards on SNS markets (Facebook in the U.S. and Germany,<br />\nVkontakte in Russia). (2) The standards seem to be temporary monopolies.<br />\nYet, no innovator survived as a standard. (3) The dominant market<br />\nposition of a standard on the SNS market alone is no problem for Article 102<br />\nof the Treaty on the Functioning of the European Union (TFEU). But if a<br />\ndominant company tries to immunize its leading position (e.g. by mergers<br />\nand acquisitions), such behavior can be scrutinized. On two-sided markets, it<br />\nwould be possible to define the relevant market much broader than the small<br />\nSNS market. When we consider the whole online advertising market as relevant,<br />\nmany of Article 102&rsquo;s problems are avoided.</p>",
