Digital market forces drive huge efficiency gains. But they also create winner-take-all dynamics that can, left unchecked, lead to monopolistic markets and hurt consumers in the long-run. Slow-moving competition policy tools are ill-equipped to fully address these digital concerns.
(1) The DMA was proposed alongside the Digital Services Act (DSA) which targets illegal goods, services and content, abuse of platforms, advertising and algorithmic transparency. The DSA concerns most online businesses.
In December 2020 the European Commission proposed the Digital Markets Act (DMA) to regulate the gatekeepers of the digital world by imposing direct restrictions on the behaviour of tech giants (1). While the Commission has not named any companies, it has proposed criteria that are sure to catch Google, Facebook, Amazon, Apple, Microsoft and SAP, among others.
This blog unpacks the different provisions of the DMA and explains why the Commission chose to regulate big tech.
What is a digital gatekeeper?
A gatekeeper is a company that acts as an important nexus between two or more groups of users – say buyers and sellers. When they attract a large share of users on one side of the platform (say buyers) gatekeepers can become unavoidable tolls on routes to certain markets or customers. Users on the other side of the platform (say sellers) may have little choice but to use the gatekeepers’ infrastructure.
The EU has thought in terms of ‘digital gatekeeper’ for as long as Google has existed. In the DMA, it defines a gatekeeper as a platform that operates in one (or more) of the digital world’s eight core services (including search, social networking, advertising and marketplaces) in at least three EU countries and:
A platform that meets these quantitative thresholds is labelled a gatekeeper. However, the Commission would retain the right to remove (or confer) ‘gatekeeper’ status by qualitative assessment. The Commission would also be empowered to alter the thresholds as technologies change, and to conduct market investigations to look for new gatekeepers.
Why big tech is big
Digital hubs are a time drain. In December 2019 (pre-COVID-19), the average Italian spent 45 hours a month on Facebook, and 24 hours on Google. The same may be true for physical marketplaces and social venues, but online, the hubs are controlled by only a handful of global players. British internet users spend 40% of their online time on sites owned by just two providers (Google and Facebook). These same two providers are frequented by 96% and 87% of British users each month. 58% of Germans book their holidays through just one site (Booking.com).
For a long time, policymakers were not especially worried about high concentration in digital markets. They assumed digital champions faced competition ‘for the market’, that is, competition from outside players keen on becoming tomorrow’s winners. After all, Facebook outcompeted MySpace. Google overtook AltaVista. Nokia once looked unassailable.
But the competitive dynamics of the early days of the internet no longer seem to apply. While the primacy of AltaVista lasted one year (and Myspace three years), a decade of that of Google and Facebook has now passed. The persistence of today’s digital leaders has become concerning: have they found a way out of the competitive race?
There are several explanations for the unusual persistence of digital leadership. For one, digital markets feature characteristics of ‘tipping markets’, or markets in which there is room for only a few players. These characteristics are the combination of:
To illustrate, consider the market for mobile operating systems (OS). OS with more end-users are naturally more attractive to app developers than OS with fewer end-users. Developers thus tend to prioritise the largest OS (an example of indirect network effects). Over time, the gap in what larger and smaller OS can offer grows. The large OS gather more user data which helps them improve the quality of their recommendations. The small OS become even less attractive, until they go bust and the winners take all. One of the reasons Microsoft abandoned the mobile market in 2017 is that it could not attract enough app makers to its OS.
Masses of data, cheap machine learning technologies and the refining of ecosystem business models have further entrenched leading positions, conferring incredible bargaining power to set commercial conditions and terms unilaterally (eg to expel, charge high fees, manipulate rankings and control reputations). Such power leaves platform users vulnerable to abuse.
Online gatekeepers are a source of concern
Success is by no means illegal. But practices that lock it in might well become unlawful. The DMA would constrain gatekeepers’ behaviour while forcing them to proactively open up to more competition. Those in breach of the rules face penalties of up to 10% of their yearly turnover and repeat offenders face being broken-up. The DMA addresses two problems: high barriers to entry and anticompetitive practices by gatekeepers. The objective is to make digital markets both contestable and fair for existing and future rivals.
To illustrate, consider the DMA’s prohibition on combining end-user data from different sources without consent. Combining data from multiple sources can give gatekeepers a significant advantage over smaller rivals. Indeed, data gleaned from one source, say online searches, can be used to predict users’ preferences in other market, say music streaming. A gatekeeper that knows the web browsing history of a user is much better positioned to predict her musical tastes than a data-poor rival. Restricting the combination of data from multiple sources, therefore, restricts the ability of gatekeepers to leverage their market power from one market to another to the detriment of small players.
Other prominent rules include:
The proposal also includes a requirement that gatekeepers inform the regulator of all mergers and acquisitions, even when the target is too small to be subject to merger control. It does not include any powers to intervene to block these mergers however (unlike the equivalent UK proposal).
As with the definition of ‘gatekeeper’, the DMA’s list of obligations is a balancing act between enforceability and flexibility. Indeed, while seven rules apply equally to all gatekeepers, the majority (eleven rules) will be tailored to each.
The practical consequences of unconstrained power
In the last few years, numerous studies (twenty-two of which are summarised here) and antitrust investigations have suggested that some gatekeepers adopted questionable practices from a competition standpoint (Table 1).
In setting the DMA list of obligations, the Commission drew on the knowledge it acquired through the various antitrust investigations: the DMA rulebook targets most of the unfair practices listed in Table 1. Take the Amazon case for example. The Commission suspects the e-retailer of gathering data on the activities of third-party sellers in order to outcompete them. One DMA obligation – for gatekeepers not to use the data of business users to compete with them – would clearly addresses the problematic practice.....
