Exploitative abuses, especially excessive pricing, have been one of the most debated forms of abuse of dominant position. Unlike exclusionary abuses, they have been prohibited only under certain jurisdictions and on rather rare occasions. In Europe there have been few recent decisions and investigations that have reiterated existing approaches and tests for establishing excessive pricing. The Turkish Competition Authority’s Sahibinden.com decision has come at such a time where the discussion on excessive pricing has been somewhat revived. However, this decision stands out as it is the first one where a competition authority has found prices to be excessive and therefore abusive in the context of a two-sided platform. Competition in platform markets display unique dynamics that may be very different from what may be observed in traditional markets especially in terms of pricing strategies. This article aims to demonstrate, through the Turkish Competition Authority’s recent decision, the difficulties in applying existing tests and criteria on excessive pricing to a two-sided platform. A thorough analysis of this decision demonstrates that competition enforcement in what may be called ‘new’ platform markets necessitates new approaches or adjustments of existing ones.

新市场上的旧滥用行为？通过双面平台处理过高的定价

剥削性滥用，尤其是过度定价，已经成为滥用支配地位的最有争议的形式之一。与排他性滥用不同，仅在某些司法管辖区和极少数情况下才禁止使用它们。在欧洲，很少有最近的决定和调查重申了建立过度定价的现有方法和测试。土耳其竞争管理局的Sahibinden.com决定是在这样的时候进行的，当时有关过高定价的讨论有所恢复。但是，这一决定是出类拔萃的，因为这是竞争管理机构发现价格过高并因此在双向平台的背景下滥用价格的第一个决定。平台市场上的竞争表现出独特的动力，这种动力可能与传统市场的动力非常不同，尤其是在定价策略方面。本文旨在通过土耳其竞争管理局最近的决定，展示将现有的过度定价测试和标准应用于双面平台的困难。对这一决定的透彻分析表明，在所谓的“新”平台市场中竞争的执行需要采用新的方法或对现有方法进行调整。
