Competition Law and Market Concepts

Understanding Two‑Sided Markets in Banking Services

Two‑sided (or bifacial) markets are platforms that bring together two distinct groups of users whose value to each other depends on participation. In banking, this often means merchants (e.g., businesses that need payment processing) and consumers (individuals who make payments). The platform’s success hinges on network effects: the more merchants join, the more attractive the service becomes for consumers, and vice‑versa.

Key Characteristics

• Two independent client groups – typically merchants and consumers.
• Interdependence: each group’s participation influences the other’s utility.
• Presence of direct or indirect network effects that amplify value as the platform grows.

Understanding these traits is essential for competition analysis because they affect market definition, pricing power, and the assessment of potential anti‑competitive conduct.

Defining an "Enterprise" under the Hôfner Test

The European Court of Justice (ECJ) in the Hôfner case established a functional definition of an enterprise for competition law purposes. An entity qualifies as an enterprise if it engages in an economic activity regardless of its legal form, ownership, or profit motive.

What Counts as an Enterprise?

• Public foundations or NGOs that offer services on a market (e.g., a foundation providing banking services).
• Private companies, partnerships, and even sole traders that sell goods or services.
• Any organization that competes for customers, even if its surplus is used for non‑profit purposes.

Conversely, entities that do not engage in market activities—such as pure regulatory bodies, charitable donors without commercial activity, or individuals buying for personal consumption—are outside the scope of competition law.

Identifying the Bifacial Nature of Platforms like Booking.com

Online travel agencies (OTAs) such as Booking.com exemplify two‑sided markets. The platform connects hotels (supply side) with travelers (demand side). The essential element that demonstrates bifaciality is the interdependence between these groups, creating network effects:

• More hotels increase the platform’s attractiveness to travelers.
• More travelers attract additional hotels seeking exposure.

This mutual reinforcement distinguishes a true two‑sided market from a simple reseller relationship.

Objective Territoriality in EU Competition Law

EU competition rules can apply to foreign entities through the doctrine of objective territoriality. The test asks whether the entity’s conduct has an immediate, substantial, and predictable effect on trade within the EU.

Key Requirements

• Immediate effect: The conduct must directly influence the EU market without requiring a chain of intermediate steps.
• Substantial effect: The impact must be significant in terms of volume, price, or market structure.
• Predictable effect: The outcome should be foreseeable based on the entity’s actions.

Physical presence, incorporation, or licensing are not decisive; what matters is the cross‑border impact of the conduct.

Concerted Practices (Practice Concertée)

EU competition law distinguishes between formal agreements and concerted practices. A concerted practice occurs when firms coordinate their behaviour without a formal contract, often through the exchange of sensitive information.

Typical Example

• Two competitors share confidential pricing data, enabling them to align future price decisions.

This exchange creates a tacit understanding that can lead to price fixing, market sharing, or output limitation, all of which are prohibited under Article 101 TFEU.

By‑Object vs. By‑Effect Restrictions

When evaluating restrictive agreements, the EU distinguishes between restrictions that are illegal by object and those illegal by effect. The decisive factor for a by‑object restriction is the inherent seriousness of the conduct, irrespective of its actual market impact.

Why Inherent Seriousness Matters

• Restrictions such as price fixing, market sharing, or output limitation are deemed so harmful that they are prohibited per se.
• The assessment does not require a detailed market analysis; the nature of the restriction alone triggers liability.

In contrast, a by‑effect analysis requires a thorough examination of market shares, competitive dynamics, and actual economic consequences.

Economic Activity and Non‑Profit Entities

Even non‑profit foundations can be classified as enterprises if they perform an economic activity. The decisive test is whether the entity offers services or goods on a market, regardless of its profit motive.

Illustrative Points

• A foundation that provides banking services competes for customers and thus engages in economic activity.
• The legal form (public, private, non‑profit) and the use of surplus are irrelevant for the competition law definition.

This principle ensures a level playing field: all market participants are subject to the same rules.

Vertical Agreements and Collective Exemptions

Vertical agreements—contracts between parties at different levels of the supply chain—may benefit from a collective exemption if they meet certain criteria. However, clauses that impose a fixed resale price (i.e., resale price maintenance) typically prevent the agreement from qualifying for the exemption.

Why Fixed Resale Prices Are Problematic

• They restrict the distributor’s freedom to set prices, potentially leading to price rigidity.
• Such clauses are considered hard‑core restrictions under the EU Vertical Block Exemption Regulation.
• Even if other parts of the agreement are benign, the presence of a hard‑core restriction disqualifies the whole contract from the exemption.

Companies should therefore avoid imposing resale price maintenance if they wish to rely on the collective exemption.

Practical Checklist for Competition Law Compliance

Use this checklist to evaluate whether your business practices align with EU competition rules:

• Market Definition: Identify all relevant client groups and assess network effects.
• Enterprise Status: Determine if your entity conducts economic activity, regardless of legal form.
• Territorial Reach: Evaluate whether your conduct has an immediate, substantial, and predictable effect on the EU market.
• Information Exchange: Avoid sharing confidential pricing or strategic data with competitors.
• Restriction Type: Classify each restrictive clause as by‑object or by‑effect; eliminate hard‑core by‑object restrictions.
• Vertical Clauses: Refrain from imposing fixed resale prices if you seek a collective exemption.

Regularly reviewing these points helps mitigate legal risk and promotes fair competition.

Conclusion

Competition law in the EU addresses a wide range of market structures—from two‑sided platforms to traditional vertical chains. By understanding the core concepts—such as the definition of an enterprise, objective territoriality, concerted practices, and the distinction between by‑object and by‑effect restrictions—businesses can navigate the regulatory landscape more confidently. Applying the practical checklist ensures compliance and supports a competitive, innovative market environment.
