Competition Law and Governance Concentration Market Power

1. Introduction

Governance concentration market power refers to a situation in which control over the rules, standards, access conditions, data, infrastructure, algorithms, platforms, or decision-making mechanisms of a market becomes concentrated in one undertaking or a small group of undertakings.

Traditional competition law focuses primarily on economic concentration—for example, a merger creating a dominant firm. Governance concentration goes further. A firm may exercise substantial market power because it governs the ecosystem in which competitors must operate.

Examples include:

• a digital platform determining access rules for dependent businesses;
• an app store controlling payment and distribution conditions;
• a technology company controlling an interoperability standard;
• a dominant infrastructure operator determining access to an essential facility;
• a platform controlling ranking, recommendation, or advertising rules;
• an industry body dominated by incumbent firms setting standards that disadvantage entrants;
• a vertically integrated firm making rules for a market in which it also competes.

The central competition-law concern is therefore:

When does control over market governance become an instrument for exclusion, discrimination, foreclosure or preservation of market power?

2. Meaning of Governance Concentration

Governance concentration can be understood through four connected forms.

A. Ownership concentration

A small number of undertakings control a large proportion of the market.

Example: Two or three firms control most of the relevant infrastructure or distribution channels.

B. Decision-making concentration

One undertaking possesses disproportionate authority to establish the rules under which other market participants operate.

C. Infrastructure concentration

A firm controls an infrastructure that competitors cannot practically avoid.

Examples:

• payment infrastructure;
• telecommunications networks;
• cloud infrastructure;
• operating systems;
• app stores;
• energy grids;
• transport infrastructure;
• digital identity systems.

D. Information concentration

A platform accumulates data that gives it the ability to monitor competitors, predict demand, optimise algorithms and potentially disadvantage rivals.

3. Governance Concentration Versus Ordinary Market Dominance

The concepts overlap but are not identical.

A firm may therefore possess governance power even where conventional price measures do not fully reveal its influence.

4. Legal Framework

Governance concentration can implicate several areas of competition law.

A. Abuse of Dominant Position

A dominant undertaking may abuse its position through:

• discriminatory access;
• refusal to deal;
• exclusionary interoperability restrictions;
• tying and bundling;
• self-preferencing;
• discriminatory ranking;
• excessive or discriminatory fees;
• exploitation of dependent businesses;
• exclusionary technical standards.

In the European Union, Article 102 TFEU is particularly important.

In India, Section 4 of the Competition Act, 2002 addresses abuse of dominant position.

In the United States, analogous concerns arise principally under Sections 1 and 2 of the Sherman Act and, depending upon the transaction or conduct, Section 7 of the Clayton Act.

5. Merger Control and Governance Concentration

Competition authorities may examine whether a merger produces excessive concentration of strategic control.

The relevant question is not simply:

"Will the merged entity have a large market share?"

It may also be:

"Will the merged entity control an infrastructure, data source, platform or ecosystem through which competitors must operate?"

Important concerns include:

• elimination of an emerging competitor;
• control of complementary technologies;
• vertical foreclosure;
• data accumulation;
• interoperability restrictions;
• increased switching costs;
• control over standards;
• control over distribution;
• ecosystem expansion.

6. Essential Facilities and Governance Power

Governance concentration becomes especially significant where an undertaking controls an essential or indispensable facility.

Competition law may become concerned when the controller:

1. possesses substantial market power;
2. controls an indispensable facility;
3. refuses or restricts access;
4. lacks legitimate justification; and
5. thereby harms effective competition.

The doctrine must nevertheless be applied cautiously because competition law generally does not impose a universal duty on firms to assist competitors.

7. Six Major Case Laws

1. United States v. Terminal Railroad Association of St. Louis (1912)

Facts

A group of railroad companies controlled the terminal facilities through which rail traffic had to pass into and out of St. Louis.

Competitors were effectively dependent upon infrastructure controlled by the association.

Issue

Whether control over an indispensable transportation facility could be used to exclude competitors.

Decision

The U.S. Supreme Court found the arrangement incompatible with the Sherman Act and required measures to prevent discriminatory exclusion.

Principle

The case is an early foundation for the essential-facilities/access-control concept.

Relevance to governance concentration

The importance of the case extends beyond railways. Control over infrastructure can create governance power because the infrastructure owner effectively determines which competitors can participate in the market.

2. United States v. Microsoft Corp. (2001)

Facts

Microsoft possessed a dominant position in PC operating systems and engaged in conduct concerning web browsers and competing technologies.

The case concerned Microsoft's use of its operating-system position to protect its broader ecosystem.

Decision

The D.C. Circuit upheld important findings of monopolization and exclusionary conduct, although it modified the district court's remedy.

Principle

A dominant firm cannot necessarily use control over one technological layer to disadvantage competing products operating at another layer.

Governance concentration significance

Microsoft demonstrates how control over a technological platform can become control over the competitive conditions of adjacent markets.

The operating system functioned not merely as a product but as an important gateway through which competing technologies reached consumers.

3. Bronner v. Mediaprint (1998)

Facts

Mediaprint operated a newspaper-delivery system in Austria. Bronner sought access to that system.

Issue

Whether a dominant undertaking could be required to provide competitors access to infrastructure under Article 86 EC, now Article 102 TFEU.

Decision

The European Court of Justice established a restrictive approach to compulsory access. The facility had to be essentially indispensable, and duplication had to be practically or economically impossible.

Principle

Dominance alone does not automatically create an obligation to share infrastructure.

Governance concentration significance

Bronner provides an important limiting principle: competition law must distinguish legitimate control over one's own infrastructure from exclusionary use of genuinely indispensable infrastructure.

4. IMS Health GmbH & Co. OHG v. NDC Health GmbH (2004)

Facts

IMS Health controlled a widely used system for organising pharmaceutical sales information in Germany.

A competitor sought access to the system.

Decision

The ECJ developed the conditions under which refusal to license intellectual property could constitute an abuse.

The circumstances included indispensability, elimination of effective competition and prevention of the emergence of a new product for which consumer demand existed.

Principle

Intellectual-property rights and competition law can conflict where control over a protected system becomes indispensable to effective competition.

Governance concentration significance

The case illustrates information and structural governance power: control over an industry architecture can make competitors dependent upon the dominant undertaking.

5. Google Shopping – Google and Alphabet v Commission (2024)

Facts

The European Commission found that Google had favoured its own comparison-shopping service in search results while placing competing comparison-shopping services at a disadvantage.

Legal significance

The General Court largely upheld the Commission's findings concerning Google's conduct.

Principle

A dominant digital platform may face competition-law scrutiny when it uses control over a critical gateway to favour its own downstream service.

Governance concentration significance

This is highly relevant to modern governance concentration because Google's search infrastructure influenced how competitors were:

• ranked;
• displayed;
• discovered;
• accessed by consumers.

The platform therefore possessed not only commercial power but significant rule-setting and visibility-control power.

6. Android Auto / Google Android Auto – Google Italy (2022)

Facts

The European Commission addressed Google's refusal to provide interoperability between its Android Auto platform and a third-party app.

Significance

The case concerned access to a digital platform and the conditions under which third-party applications could interact with it.

Principle

Digital ecosystem operators may face competition concerns where control over interoperability becomes a mechanism for restricting complementary services.

Governance concentration significance

The case demonstrates that technical governance itself can have competitive consequences.

A platform can influence competition through:

• APIs;
• compatibility rules;
• certification;
• technical permissions;
• access requirements.

8. Additional Important Case Laws

7. Commercial Solvents v Commission (1974)

The EU courts addressed a dominant firm's refusal to supply an important input to a downstream competitor.

Principle

A dominant undertaking controlling an important upstream input cannot use that control simply to eliminate competition downstream.

Governance relevance

Vertical control can become governance power where the upstream input is indispensable for participation in the downstream market.

8. MCI Communications Corp. v AT&T (1983)

The U.S. Seventh Circuit discussed the essential-facilities doctrine in the telecommunications context.

Relevance

The case helped develop the framework concerning:

• control of an essential facility;
• competitor inability reasonably to duplicate it;
• denial of access;
• feasibility of providing access.

It illustrates how network infrastructure can create structural market power.

9. Oscar Bronner and the Modern Digital Economy

Bronner is particularly important when analysing modern platforms because it prevents the concept of governance concentration from becoming an automatic rule that every large platform must provide competitors with access.

The distinction is:

Control + indispensability + exclusionary effect + lack of legitimate justification

rather than simply:

Large firm + refusal to share = violation.

10. Governance Concentration in Digital Markets

Digital markets make governance concentration especially significant.

A platform may simultaneously act as:

1. infrastructure provider;
2. marketplace;
3. rule-maker;
4. competitor;
5. data collector;
6. advertising intermediary;
7. payment intermediary; and
8. ranking authority.

This creates a potential dual-role problem.

Example

Suppose Platform A operates:

• a marketplace;
• the marketplace's search algorithm;
• its payment system; and
• competing private-label products.

Platform A may establish rules affecting:

• search ranking;
• commissions;
• access;
• product visibility;
• payment conditions;
• seller eligibility.

If Platform A simultaneously competes with the sellers subject to those rules, governance concentration may create incentives for self-preferencing or discriminatory treatment.

11. Self-Preferencing

Self-preferencing occurs where a platform gives preferential treatment to its own products or services.

Possible mechanisms include:

• preferential ranking;
• better placement;
• access to data;
• lower fees;
• faster technical integration;
• favourable recommendations;
• preferential interoperability.

The competition-law inquiry should examine:

1. whether the undertaking is dominant;
2. whether it controls an important gateway;
3. whether competitors depend upon that gateway;
4. whether the platform treats its own service differently;
5. whether the conduct forecloses competitors;
6. whether there is an objective or efficiency justification.

12. Interoperability Governance

Interoperability can become a competition issue when a dominant undertaking controls the technical rules determining whether competing products can interact with its system.

Examples include:

• messaging interoperability;
• payment APIs;
• operating systems;
• smart-home ecosystems;
• cloud services;
• automotive software;
• wearable devices;
• digital identity systems.

A dominant firm could potentially strengthen its position by:

controlling the technical interface → restricting interoperability → increasing switching costs → weakening competitors → reinforcing dominance.

13. Data Governance Concentration

Data can produce another form of governance power.

A dominant platform may control:

• consumer behaviour data;
• transaction data;
• advertising data;
• search data;
• location data;
• seller-performance data;
• algorithmic feedback;
• interoperability data.

The competitive problem is not necessarily simply the possession of data.

The relevant question is whether the data advantage:

• prevents effective entry;
• creates substantial switching costs;
• permits discriminatory treatment;
• facilitates exclusion;
• enables leveraging into adjacent markets.

14. Algorithmic Governance

Modern platforms increasingly govern markets through algorithms rather than human decisions.

An algorithm can determine:

• prices;
• ranking;
• visibility;
• access;
• recommendations;
• advertising allocation;
• seller eligibility;
• commission levels.

Consequently, algorithmic governance may become a new form of market power.

Competition authorities may examine whether algorithmic systems:

• facilitate coordination;
• discriminate against rivals;
• favour affiliated businesses;
• exploit dependent businesses;
• create exclusionary switching costs.

15. Network Effects and Governance Concentration

Network effects can reinforce governance concentration.

A simplified cycle is:

More users

↓

More data

↓

Better service / stronger ecosystem

↓

More business users

↓

More network effects

↓

Higher switching costs

↓

Greater dependence

↓

Greater governance power

This creates the possibility of self-reinforcing market power.

16. Collective Governance and Industry Standards

Governance concentration does not always involve a single company.

An industry association or standards body may become an important market-governance institution.

Competition concerns can arise where competing firms collectively:

• determine technical standards;
• restrict access to standards;
• exclude disruptive technologies;
• exchange competitively sensitive information;
• impose discriminatory certification requirements.

Standard-setting can therefore simultaneously promote interoperability and create opportunities for exclusion.

17. Competition Risks

The principal competition risks include:

1. Foreclosure

Competitors may be prevented from entering or expanding.

2. Discrimination

The infrastructure controller may impose different conditions on independent competitors.

3. Self-preferencing

The controller may favour its own downstream products.

4. Leveraging

Market power in one market may be transferred to another.

5. Raising rivals' costs

Access fees or technical conditions may make competitors less competitive.

6. Innovation suppression

Entrants may be unable to introduce competing technologies.

7. Switching-cost escalation

Consumers or businesses become increasingly dependent upon one ecosystem.

8. Entrenchment

Governance control reinforces an already powerful market position.

18. Efficiency and Legitimate Governance

Not every concentration of governance power is anticompetitive.

Centralised governance can produce legitimate benefits, including:

• common technical standards;
• improved security;
• fraud prevention;
• quality assurance;
• interoperability;
• consumer protection;
• lower transaction costs;
• innovation coordination.

Therefore, competition analysis should distinguish between:

legitimate governance
and
governance used as an exclusionary instrument.

19. Possible Competition-Law Remedies

Authorities may employ several remedies.

Structural remedies

• divestiture;
• separation of business units;
• prohibition of certain acquisitions.

Behavioural remedies

• non-discrimination obligations;
• transparent access criteria;
• interoperability requirements;
• data-access requirements;
• restrictions on self-preferencing.

Technical remedies

• API access;
• portability;
• interoperability;
• technical compatibility;
• neutral ranking mechanisms.

Governance remedies

Particularly important in this context are requirements concerning how market rules are created and applied.

For example:

transparent rules + equal access + independent review + non-discriminatory implementation.

20. Governance Concentration and Merger Control

Merger authorities increasingly have to consider whether a transaction gives an undertaking control over several layers of an ecosystem.

For example:

Infrastructure + Data + Platform + Distribution + Downstream Service

can generate greater competitive significance than any individual market share suggests.

A transaction may therefore create:

concentration of economic power + concentration of infrastructural power + concentration of informational power + concentration of governance power.

21. Key Analytical Test

A useful competition-law framework is:

Step 1 — Define the relevant market

Identify the product, service, technology or infrastructure concerned.

Step 2 — Identify the governance function

Ask:

Who makes the rules governing participation?

Step 3 — Determine market power

Consider:

• market share;
• barriers to entry;
• network effects;
• switching costs;
• data advantages;
• control of infrastructure.

Step 4 — Identify dependency

Determine whether competitors, suppliers or customers depend upon the governance system.

Step 5 — Examine discriminatory conduct

Compare treatment of:

• independent competitors;
• affiliated businesses;
• internal products;
• external users.

Step 6 — Analyse foreclosure

Ask whether the governance mechanism substantially reduces competitors' ability to compete.

Step 7 — Examine justification

Consider:

• security;
• quality;
• technical necessity;
• efficiency;
• consumer protection;
• legitimate business objectives.

Step 8 — Assess remedies

Determine whether competition can be protected through:

• access;
• interoperability;
• non-discrimination;
• transparency;
• data portability;
• structural separation.

23. Key Principles Emerging from the Case Law

24. Conclusion

Governance concentration market power represents an important evolution of traditional competition-law analysis. Market power is no longer limited to the ability to increase prices. In platform and infrastructure-intensive markets, power may arise from the ability to set the rules through which other undertakings compete.

The most important competition-law question is therefore not merely:

Who has the largest market share?

It is also:

Who controls the infrastructure, information, standards, interfaces and rules through which competition takes place?

The case law—from Terminal Railroad, Microsoft, Bronner and IMS Health to Google Shopping and Android Auto—shows the gradual development of competition-law principles addressing access, interoperability, technological control and exclusion.
