Martin Cave ‘Platform Software Versus the Software of Competition Law’ (2019) Journal of European Competition Law & Practice 10(7) 472

The emergence of two-sided platforms challenges competition law to adapt its ‘software’—the practical way in which cases are addressed. Competition authorities carefully and conservatively manage competition policy’s operating system, but the radical nature of multi-sidedness imposes major challenges. The purpose of this article, available here, is to discuss how these challenges might be addressed in practice. This is done by reference to a two-sided platform merger inquiry that was undertaken by the UK Competition and Markets Authority (CMA) in 2017. The case concerned two merging food-ordering platforms that linked restaurants and customers, and accounted for 80% of the market (with the merger leading to a 10% increment).  A monetary transfer linked the two sides of the market – these platforms were usually rewarded by a percentage of the customers’ bill.

This article, available here, considers the rise and growth of this industry, the power it has bestowed on a handful of platforms, and the possible implications for consumer welfare and competition. Section 2 describes the pervasiveness of third-party tracking. Third-party tracking is a mechanism through which a company (the third-party tracker) hooks onto another (first-party) website or application and collects identifiable data about users, enabling the tracker to build a comprehensive profile about these users. Tracking may occur both actively and passively. It may offer generic information on usage and webpage visits, or combined and analysed information which enables the identification of the individual. The gathering of personalised data – through third-party tracking or otherwise – is primarily relied upon for four purposes in the digital realm: to provide data-based (i.e. individualized or targeted)…
