Competition Law and Information Advantages and Dominance

1. Introduction

Information advantages arise when an undertaking possesses superior access to, control over, quality of, or ability to process commercially relevant information compared with its competitors.

In modern markets, information can itself constitute an important competitive asset. A firm may obtain information through:

customer transactions;

search activity;

digital platforms;

industrial databases;

supply-chain systems;

loyalty programmes;

payment networks;

cloud services;

advertising systems;

Internet-of-Things devices;

AI systems;

marketplace operations.

An information advantage is not inherently anti-competitive. Businesses routinely compete by developing better information, analytics and technology.

The competition-law concern arises when a powerful undertaking uses a significant information advantage to exclude competitors, restrict market access, discriminate against rivals, exploit customers, or reinforce an existing dominant position.

2. Information as a Source of Market Power

Traditional market power is often associated with:

market share;

pricing power;

control over supply;

barriers to entry.

Digital and data-intensive markets introduce another dimension:

Control over strategically valuable information can reinforce market power.

For example, a marketplace operator may know:

what customers are searching for;

which products are selling;

the prices charged by suppliers;

inventory levels;

customer conversion rates;

demand patterns.

If the operator also sells products competing with its marketplace sellers, the information advantage can potentially give it a significant competitive advantage.

3. Types of Information Advantages

A. Exclusive information

Information that competitors cannot reasonably obtain.

Examples:

proprietary industrial databases;

exclusive transaction histories;

confidential customer information.

B. Superior scale of information

Information available to many firms but possessed in much greater quantity by one undertaking.

C. Real-time information

Information that becomes valuable because it is available immediately.

Examples include:

real-time prices;

inventory;

demand;

traffic;

financial transactions.

D. Predictive information

AI and machine-learning systems can transform historical information into forecasts about:

consumer demand;

prices;

customer behaviour;

supply shortages;

market entry.

E. Cross-market information

A platform may combine information from several businesses or markets.

This can create an advantage unavailable to single-market competitors.

4. Information Advantages and Dominance

Competition law generally does not prohibit a company merely because it possesses better information.

The critical questions are:

Does the undertaking possess substantial market power?

Is the information strategically important?

Is the information difficult for competitors to obtain?

Does the undertaking use the information to exclude competitors?

Does it discriminate between trading partners?

Does information control create substantial entry barriers?

Does the conduct reduce innovation or consumer choice?

Thus:

Information advantage ≠ automatically dominance

and:

Dominance ≠ automatically unlawful

The issue is generally the use or exploitation of market power.

5. Information as an Entry Barrier

Large information holdings can make entry difficult.

A new competitor may need:

customer data;

historical transaction data;

behavioural data;

supplier information;

technical information;

training data;

reputation data.

An incumbent possessing these resources may improve its services faster than new entrants.

This can create a data-driven entry barrier.

6. Network Effects and Information Advantages

Information advantages often interact with network effects.

For example:

More users → more transactions → more data → better algorithms → better service → more users.

This creates a feedback loop.

The incumbent may therefore accumulate information faster than a new entrant.

Competition authorities may need to assess whether such feedback mechanisms make the market contestable.

7. Information Asymmetry

Information asymmetry exists when one market participant possesses substantially more relevant information than another.

A dominant platform might know:

suppliers' prices;

suppliers' margins;

customer preferences;

product performance;

demand forecasts.

The suppliers themselves may not have equivalent information about the overall market.

This asymmetry can become problematic if the platform uses the information to compete against the businesses from which it obtained the information.

8. Case Law: United States v. Microsoft Corp.

The Microsoft antitrust litigation is a foundational case concerning technological market power.

Microsoft possessed a dominant position in PC operating systems and used aspects of its control over the operating-system environment to affect competition in adjacent software markets.

Competition principle

Control over an important technological platform can provide opportunities to restrict competitors in neighbouring markets.

Information-advantage relevance

Modern operating systems can provide extensive information concerning:

application usage;

user behaviour;

technical performance;

developer activity.

Where such information is combined with platform control, it can potentially reinforce ecosystem dominance.

9. Case Law: Google Shopping

The European Commission's Google Shopping case provides an important example of information and search infrastructure affecting competition.

Google controlled a major search-discovery infrastructure while also operating its own comparison-shopping service.

The Commission found that Google gave preferential treatment to its comparison-shopping service in search results.

Competition principle

Control over a key information-discovery gateway can influence competition in downstream markets.

Information-advantage relevance

Search data and user behaviour can provide valuable information concerning:

consumer preferences;

product demand;

clicks;

conversion;

commercial trends.

The case illustrates how control over information-discovery infrastructure can interact with market power.

10. Case Law: Google Android

The Google Android proceedings involved Google's position within the mobile-device ecosystem.

The European Commission examined contractual arrangements involving:

mobile operating systems;

application stores;

search;

browser distribution.

Competition principle

Market power in one technological layer may be leveraged into interconnected markets.

Information relevance

Mobile ecosystems generate extensive information concerning:

application usage;

search behaviour;

user engagement;

device activity.

Control over several layers of the ecosystem can potentially provide information advantages unavailable to independent competitors.

11. Case Law: IMS Health v. Commission

IMS Health concerned a commercially significant pharmaceutical data structure.

The case is particularly relevant to the question of when control over information may justify competition-law intervention.

The European courts considered circumstances in which refusal to provide access to a commercially important information resource could amount to abusive conduct.

Competition principle

Information infrastructure can become competitively significant where stringent conditions concerning indispensability and elimination of competition are satisfied.

Relevance

The case is important for understanding:

proprietary databases;

data access;

information monopolisation;

refusal to license.

12. Case Law: Bronner v. Mediaprint

Bronner concerned access to an existing newspaper distribution system.

Although the case did not concern a modern digital database, its principles are important when considering whether a dominant undertaking controlling an important resource must provide access to competitors.

Competition principle

The threshold for requiring access to infrastructure controlled by a dominant firm is demanding.

Information relevance

The same analytical caution applies to information resources: not every valuable database or information advantage automatically creates a competition-law duty to share it.

13. Case Law: Commercial Solvents

Commercial Solvents concerned a dominant undertaking's refusal to supply an input to downstream competitors.

Competition principle

A dominant undertaking may abuse its position where it uses control over an upstream resource to restrict downstream competition.

Information relevance

The principle can extend conceptually to information infrastructure where an undertaking controls information that functions as an important competitive input.

Examples might include:

essential technical information;

industry databases;

interoperability information;

transaction information.

14. Case Law: United Brands

United Brands is a leading European authority concerning dominance and discriminatory conduct.

The case involved the use of market power in a distribution system.

Information-advantage relevance

Modern distribution platforms possess extensive information about:

customer demand;

distributor behaviour;

geographic sales;

pricing.

The case helps illustrate the broader principle that dominant firms cannot use market power in ways that unfairly discriminate between trading partners.

15. Case Law: Hoffmann-La Roche

Hoffmann-La Roche concerned loyalty-inducing arrangements imposed by a dominant undertaking.

Competition principle

Contractual mechanisms used by dominant firms can restrict competitors' ability to obtain sufficient access to customers.

Information relevance

Modern platforms can use information to create highly targeted loyalty incentives.

For example, a platform may identify:

customers likely to switch;

suppliers dependent on the platform;

competitors' vulnerable customers.

The information can then be used to design exclusionary incentives.

16. Case Law: Intel

Intel concerned rebates and exclusionary conduct.

The case is important because dominant-firm incentive systems may have competitive effects depending upon their structure and circumstances.

Information advantage

A sophisticated platform can use transaction information to target rebates at:

marginal customers;

strategically important suppliers;

emerging competitors.

Information therefore can make exclusionary strategies more precise.

17. Case Law: Meta Platforms / Facebook Data Issues

European competition proceedings concerning Meta have also highlighted the relationship between data collection, platform power and competition.

The central economic issue is that data generated through one service can potentially strengthen another commercial activity.

Competition relevance

Data aggregation can:

increase targeting capabilities;

strengthen advertising advantages;

increase switching costs;

create barriers for rivals.

The legal treatment depends upon the particular conduct and applicable competition-law framework.

18. Data Combination

A major competition concern arises when a company combines information from multiple services.

For example:

Search data + shopping data + location data + advertising data

can produce a much more detailed commercial profile than any individual dataset.

Competition analysis may therefore consider whether data combination:

creates a significant competitive advantage;

forecloses rivals;

reduces privacy-related competition;

raises entry barriers.

19. Information Advantage in Industrial Markets

The issue is not restricted to consumer platforms.

Industrial companies may possess:

machine-performance data;

production data;

supply-chain information;

procurement data;

inventory data;

logistics information;

energy-consumption data.

An industrial platform may collect information from numerous manufacturers and then use aggregated information to compete against them.

This creates a particularly important vertical information asymmetry.

20. Marketplace Information Advantages

Consider an industrial marketplace where 10,000 suppliers sell products.

The marketplace knows:

every supplier's price;

transaction volume;

customer preferences;

product demand;

inventory;

conversion rates.

If the marketplace subsequently launches its own private-label products, it may be able to use marketplace data to determine:

which products are profitable;

optimal prices;

customer demand;

weak competitors;

geographical opportunities.

This can create competition concerns where the information is used to disadvantage participating suppliers.

21. Search and Ranking Information

Search platforms can possess information about:

queries;

clicks;

purchases;

user interests;

geographic demand.

Ranking algorithms then determine which businesses receive attention.

This produces two interconnected forms of power:

Information advantage

and

visibility control.

A platform possessing both may have significant influence over downstream competition.

22. Algorithmic Information Advantages

AI systems can amplify information advantages.

An AI system can process enormous datasets to predict:

prices;

demand;

customer behaviour;

competitor strategies;

inventory shortages.

This can create a competitive advantage beyond simple possession of raw data.

The relevant economic resource may therefore be:

data + computational capacity + algorithms + feedback loops.

23. Information Advantage and Algorithmic Pricing

Algorithms may allow firms to respond to market information much faster.

Potential competition concerns include:

automated price alignment;

monitoring competitors' prices;

dynamic pricing;

personalised pricing;

algorithmic coordination.

However, algorithmic pricing itself is not unlawful.

The legal issue depends on whether there is conduct that satisfies the applicable competition-law requirements.

24. Information Exchange Between Competitors

Competition law can also regulate information exchange.

Competitors exchanging information about:

future prices;

production plans;

capacity;

customers;

output;

may reduce strategic uncertainty.

This can facilitate coordination.

Digital platforms can unintentionally become conduits for such exchanges because they aggregate information from competing firms.

25. Information Advantages and Self-Preferencing

A platform may obtain information from independent businesses and then compete against those businesses.

Potential conduct includes:

collecting supplier data;

analysing demand;

identifying successful products;

launching competing products;

giving those products preferential placement.

The competition-law question is whether the platform's use of information constitutes exclusionary conduct or merely legitimate competition based on information obtained through ordinary commercial activity.

26. Data Portability

Data portability can reduce information-based entry barriers.

If users can transfer their:

transaction history;

customer relationships;

reputation;

business information;

to competing platforms, switching becomes easier.

This may reduce the incumbent's informational advantage.

27. Interoperability

Interoperability can similarly reduce informational lock-in.

For example, competing systems may be able to exchange:

customer information;

transaction data;

technical information;

authentication records.

Where interoperability is technically feasible, restrictions may increase the incumbent's competitive advantage.

28. Information Monopolisation

The phrase information monopolisation should be used carefully.

Possessing a large amount of information does not automatically constitute monopolisation.

Competition-law analysis should establish:

the relevant market;

the competitive significance of the information;

market power;

barriers to obtaining alternatives;

the undertaking's conduct;

actual or likely foreclosure.

29. Indian Competition-Law Perspective

Under India's Competition Act, 2002, information advantages may be relevant particularly under Section 4, where a dominant enterprise uses control over information to engage in conduct such as:

discriminatory treatment;

denial of market access;

unfair conditions;

leveraging;

tying;

exclusionary conduct.

Section 3 may apply where competitors use information-sharing arrangements to coordinate their conduct.

Sections 5 and 6 may become relevant where combinations substantially increase control over strategically important data or information ecosystems.

30. Possible Competition-Law Theories of Harm

Information advantages can support several theories of harm.

1. Foreclosure

Competitors are prevented from obtaining sufficient customers or suppliers.

2. Raising rivals' costs

Competitors must spend substantially more to acquire equivalent information.

3. Entry barriers

New entrants cannot obtain the necessary data at reasonable cost.

4. Self-preferencing

The information holder favours its own downstream operations.

5. Discrimination

The undertaking provides information access selectively.

6. Exploitation

The undertaking imposes unfair conditions because counterparties are information-dependent.

31. Possible Efficiency Benefits

Information advantages can also create significant efficiencies.

They can facilitate:

better product development;

fraud prevention;

demand forecasting;

supply-chain optimisation;

lower transaction costs;

personalised services;

improved quality;

reduced waste;

better resource allocation.

Competition law therefore should not treat information concentration as inherently harmful.

The key issue is how the information advantage affects competitive process and market contestability.

32. Remedies

Depending on the circumstances, competition authorities may consider:

Data-access remedies

Requiring access under appropriate conditions where legally justified.

Data portability

Allowing customers to transfer information.

Interoperability

Requiring technical compatibility.

Non-discrimination

Preventing discriminatory treatment of competing businesses.

Firewalls

Separating competitively sensitive information obtained through one business from a competing business.

Transparency

Requiring disclosure of relevant ranking or access criteria where appropriate.

33. Compliance Measures

Businesses possessing significant information advantages should consider:

identifying strategically sensitive data;

separating customer information from competitive decision-making where appropriate;

limiting internal access;

establishing data-use policies;

reviewing information-sharing arrangements;

monitoring algorithmic use of competitor information;

evaluating self-preferencing risks;

assessing discriminatory access;

documenting legitimate business justifications;

conducting competition-law audits of data practices.

34. Comparative Case-Law Table

35. Key Legal Principles

Several principles emerge from the case law:

First

Information is capable of being an important competitive asset.

Second

Possession of superior information is not by itself unlawful.

Third

A dominant undertaking's use of information can become problematic when it facilitates exclusionary conduct.

Fourth

Control over indispensable information may raise access questions, but the legal threshold for compulsory access is demanding.

Fifth

Information advantages become particularly significant when combined with network effects, switching costs and platform control.

Sixth

Competition authorities increasingly need to consider non-price competitive parameters such as data, privacy, quality, innovation and access.

36. Conclusion

Information advantages can be an important source and amplifier of market dominance in modern competition law. The competitive significance of information becomes particularly strong when a business simultaneously controls:

data + users + infrastructure + algorithms + distribution.

Such an undertaking may be able to understand market conditions more accurately than competitors, target commercial incentives more effectively, identify emerging rivals, optimise its products and influence access to customers.

Nevertheless, information superiority should not itself be equated with an infringement of competition law. The central inquiry is whether the information advantage results from legitimate competition or is being combined with dominance and exclusionary conduct to undermine the competitive process.

The principles developed in Microsoft, Google Shopping, Google Android, IMS Health, Bronner, Commercial Solvents, United Brands, Hoffmann-La Roche and Intel provide a useful framework for analysing information-driven dominance across digital, industrial, financial and platform markets.
