DIGITAL MARKETS AND COMPETITION LAW

As digitalization reshapes many sectors of the global economy, digital markets are also growing rapidly. These markets, dominated particularly by large technology companies, raise significant legal questions regarding the protection of competition and the safeguarding of consumer rights. Competition law plays a crucial role in the development of digital markets.

Characteristics and Structure of Digital Markets

Digital marketplaces refer to an ecosystem where goods and services are offered through online platforms. E-commerce sites, social media platforms, search engines, and cloud service providers are key elements operating in digital marketplaces. These marketplaces have some distinct characteristics compared to other marketplaces:

• Network Effect: On digital platforms, one user's participation increases the participation of other users. For example, an increase in the number of users on a social media platform increases its attractiveness, drawing in even more users.
• Data-Driven Business Models: Companies in digital marketplaces collect large amounts of data on consumer behavior and develop strategies based on this data. This is changing the nature of competition, especially in areas such as personalized advertising.
• Platform Dominance: Large technology companies can act as a kind of "gatekeeper" in the market, making it difficult for other smaller companies to enter.

The Relationship Between Digital Markets and Competition Law

Competition law aims to protect competition in the market and ensure that market players avoid unfair competition. Actions that restrict competition in digital markets can be more complex than in traditional markets. In this context, the dynamic nature of digital markets presents significant challenges for competition law practitioners.

Competition law in Turkey Law No. 4054 on the Protection of Competition . Within the framework of this law, digital markets have also been scrutinized, and various regulations have been made regarding competition violations. Three main issues are particularly emphasized in order to protect competition in digital markets:

1. Abuse of Dominant Position

   Companies that hold a dominant position in digital marketplaces may engage in actions that restrict competition. For example, a large technology company might unfairly block access to competitors' products on its own platform. Such behavior constitutes a restriction of competition and is considered "abuse of dominant position" under Article 6 of the Competition Law.

   Example: A search engine prioritizing its own services in search results and pushing competing services to the back is a good example of this.

2. Agreements that Restrict Competition

   In digital marketplaces, some agreements between firms can restrict competition. Actions such as price fixing and market sharing are prohibited by law. Agreements made through digital platforms are also subject to scrutiny under this law. Article 4 of Law No. 4054 prohibits such agreements.

   Example: An agreement between two large e-commerce platforms to set prices and not compete constitutes a restriction of competition.

3. Mergers and Acquisitions

   In digital marketplaces, large companies tend to increase their market dominance by acquiring or merging with competitors. Such transactions can reduce the chances of smaller firms competing. In Türkiye, the Competition Authority examines mergers and acquisitions of large digital firms and assesses whether competition is negatively affected. Based on Article 7, the Competition Authority monitors such transactions and intervenes if necessary.

National and International Regulations

Since digital markets are not limited to national borders, international competition law regulations must also be taken into account. The European Union the Digital Markets Act (DMA) . These regulations include measures to be taken against anti-competitive behavior by large digital platforms. In Turkey, new regulations regarding digital markets are also being considered, in parallel with European Union regulations.

Protection of Consumer Rights

Competition law not only regulates the relationships between market players but also protects consumer rights. Anti-competitive actions by firms operating in digital marketplaces can make it more difficult for consumers to access products and services and lead to price increases. The Competition Authority has undertaken the mission of protecting the rights of both consumers and small firms to prevent such situations.

The Role of the Competition Authority

In Turkey, the Competition Authority is responsible for overseeing and protecting competition in digital markets . The Authority investigates competition violations in digital markets and imposes administrative sanctions when necessary. Particularly in recent years, oversight of digital platforms has increased, and deterrent penalties have been applied against companies engaging in anti-competitive practices.

Some of the responsibilities of the Competition Authority regarding digital markets are as follows:

• To monitor the abuse of power by dominant companies,
• To prevent agreements that restrict competition,
• To review and approve mergers and acquisitions,
• To protect the rights of consumers and small businesses.

Conclusion

Digital marketplaces have become a rapidly growing and dynamic part of the economy. Ensuring that these marketplaces operate fairly and freely is crucial for protecting consumers and small businesses. Competition law serves as a fundamental tool in regulating digital marketplaces and preventing unfair competition. In Türkiye, the Competition Authority's supervisory and intervention powers play a critical role in ensuring a fair competitive environment in digital marketplaces.
