Competition Law and Future Institutional Design of Competition Authorities

Introduction

Competition authorities are undergoing a fundamental transformation. Traditional competition-law institutions were designed primarily to examine price, output, market shares, mergers, cartels and exclusionary conduct within relatively identifiable markets. Modern markets, however, are increasingly characterised by digital platforms, artificial intelligence, algorithms, ecosystems, data accumulation, network effects, multi-sided markets, automated decision-making, cloud infrastructure and cross-border commercial activity.

The future institutional design of competition authorities must therefore address not merely the question of what conduct is prohibited, but also how competition authorities should be structured, equipped and coordinated to detect, investigate and remedy increasingly complex forms of market power.

The emerging institutional model is likely to combine:

1. Independent competition authorities;
2. Specialised digital and technology units;
3. Data-science and algorithmic-investigation capabilities;
4. Greater international cooperation;
5. Ex ante regulation for systemically important platforms;
6. Stronger merger-review capabilities;
7. Market-monitoring and early-warning systems;
8. Procedural safeguards and judicial review; and
9. Coordination with sectoral regulators and data-protection authorities.

I. Meaning of Institutional Design of Competition Authorities

Institutional design refers to the way in which a competition authority is organised and empowered to perform its functions.

It includes:

• statutory independence;
• appointment and removal of officials;
• investigative powers;
• adjudicatory powers;
• merger-control authority;
• market-investigation powers;
• technical expertise;
• budgetary autonomy;
• international cooperation;
• relationship with sectoral regulators;
• procedural safeguards;
• enforcement priorities; and
• mechanisms for judicial review.

A competition authority therefore has both a legal architecture and an institutional architecture.

Traditional model

The traditional authority generally operated through:

Complaint → Investigation → Legal assessment → Decision → Penalty/remedy → Judicial review

Future model

The emerging model is more dynamic:

Market monitoring → Data collection → Algorithmic detection → Preliminary assessment → Investigation → Interim measures → Remedy → Continuous monitoring

This represents a shift from reactive enforcement to continuous competition governance.

II. Why Institutional Design Must Change

1. Digitalisation of markets

Digital markets may involve:

• platforms;
• app stores;
• search engines;
• online marketplaces;
• digital advertising;
• cloud computing;
• artificial intelligence;
• payment systems; and
• digital ecosystems.

Market power may arise from factors other than price.

These include:

• data advantages;
• network effects;
• switching costs;
• interoperability;
• ecosystem dependence;
• default settings;
• algorithms; and
• control over technical infrastructure.

Consequently, authorities need technological expertise alongside traditional legal and economic expertise.

III. From Market-by-Market Analysis to Ecosystem Analysis

Traditional competition law often defines:

relevant product market + relevant geographic market + market power + conduct + effects.

Future competition authorities may increasingly have to examine ecosystems.

For example, a technology company may simultaneously operate:

• an operating system;
• app store;
• payment system;
• advertising network;
• cloud service;
• browser;
• search engine; and
• hardware ecosystem.

The competitive concern may not arise from one isolated product but from the interaction between several products.

Therefore, institutional design must enable authorities to examine interconnected markets.

IV. Independence of Competition Authorities

Institutional independence is one of the central requirements of effective competition enforcement.

An authority should have:

• independent decision-making;
• transparent appointment procedures;
• protection against arbitrary removal;
• predictable funding;
• professional staffing;
• operational autonomy; and
• safeguards against political or commercial interference.

Independence does not mean absence of accountability.

A modern authority should instead operate under:

Independence + Transparency + Judicial Review + Parliamentary/Public Accountability

V. Specialised Digital Competition Units

Future authorities are likely to contain dedicated units dealing with:

A. Digital economics

Experts should analyse:

• network effects;
• multi-sided markets;
• switching costs;
• zero-price markets;
• platform incentives;
• data advantages.

B. Technology

Technology specialists should understand:

• APIs;
• cloud infrastructure;
• operating systems;
• blockchain;
• machine learning;
• interoperability;
• platform architecture.

C. Algorithms

Authorities increasingly need specialists capable of examining:

• algorithmic pricing;
• recommendation systems;
• ranking algorithms;
• self-preferencing;
• automated exclusion;
• algorithmic collusion.

D. Data science

Authorities should be able to analyse massive datasets rather than depend exclusively upon documents voluntarily supplied by investigated companies.

VI. Institutional Design and Artificial Intelligence

Artificial intelligence presents a particularly important institutional challenge.

AI systems can potentially influence:

• pricing;
• product recommendations;
• search rankings;
• advertising;
• consumer targeting;
• credit allocation;
• supply-chain decisions.

Competition authorities may therefore require AI audit capabilities.

An AI competition unit could examine:

1. training data;
2. access to computing resources;
3. model concentration;
4. interoperability;
5. APIs;
6. model distribution;
7. vertical integration;
8. algorithmic pricing;
9. exclusionary technical design; and
10. discriminatory access conditions.

VII. Ex Ante and Ex Post Institutional Models

Traditional competition authorities primarily operate ex post.

They investigate conduct after it has occurred.

Future institutional frameworks may combine:

Ex post enforcement

Used for:

• cartels;
• abuse of dominance;
• exclusionary conduct;
• anticompetitive agreements.

Ex ante regulation

Used where markets have structural characteristics that make delayed intervention particularly harmful.

This model can be seen in the development of special regulatory frameworks for major digital platforms.

The institutional challenge is determining which matters should remain within ordinary competition law and which require continuous regulatory supervision.

VIII. Merger-Control Capabilities

Future authorities will need to examine mergers involving:

• data;
• algorithms;
• cloud infrastructure;
• AI models;
• intellectual property;
• digital ecosystems;
• emerging competitors.

Traditional turnover thresholds may fail to capture strategically important acquisitions by dominant technology companies.

Therefore authorities may require:

• transaction-value thresholds;
• mandatory notification for designated firms;
• strengthened information-gathering powers;
• post-merger monitoring;
• remedies capable of addressing ecosystem effects.

IX. Market-Monitoring Functions

A future competition authority should not necessarily wait for a complaint.

It may continuously monitor:

• prices;
• algorithms;
• market shares;
• platform terms;
• merger activity;
• access conditions;
• switching costs;
• interoperability;
• consumer complaints.

This produces an early-warning competition system.

The authority can identify structural risks before they develop into serious exclusionary conduct.

X. Coordination With Sectoral Regulators

Many modern markets fall simultaneously within several regulatory regimes.

For example:

Future institutional design therefore requires formal cooperation mechanisms.

These may include:

• information sharing;
• joint investigations;
• memoranda of understanding;
• coordinated remedies;
• referral mechanisms;
• joint market studies.

XI. International Cooperation

Digital markets frequently operate across borders.

A platform may:

• be incorporated in one jurisdiction;
• store data in another;
• employ users globally; and
• provide services worldwide.

Competition authorities consequently need mechanisms for:

• evidence sharing;
• dawn-raid coordination;
• merger cooperation;
• cross-border investigations;
• information exchange;
• coordinated remedies.

International cooperation is particularly important because unilateral enforcement may produce inconsistent obligations.

XII. Case Laws

1. United States v. Microsoft Corp. — 253 F.3d 34 (D.C. Cir. 2001)

Facts

Microsoft was accused of maintaining monopoly power in the market for Intel-compatible PC operating systems and engaging in conduct designed to protect that position.

The case involved Microsoft's relationship with:

• Internet browsers;
• operating systems;
• software developers; and
• computer manufacturers.

Institutional significance

The case demonstrated that competition authorities need expertise capable of understanding technological ecosystems, rather than merely conventional price competition.

Principle

A dominant technology firm's control over one technological layer may allow it to influence competition in adjacent markets.

Future institutional lesson

Competition authorities should develop:

• technology expertise;
• software-market expertise;
• interoperability analysis;
• technical investigative capabilities.

2. United States v. Google LLC — Search and Search Advertising Litigation

The U.S. Google litigation illustrates the institutional difficulties associated with investigating large digital ecosystems.

The competition issues include:

• search distribution;
• default arrangements;
• exclusionary agreements;
• advertising technology;
• network effects; and
• access to distribution channels.

Institutional significance

The case illustrates why competition authorities need to understand:

• platform economics;
• default settings;
• distribution agreements;
• data;
• network effects.

Future lesson

Authorities should possess specialised digital-market investigation teams capable of examining technical and commercial relationships simultaneously.

3. European Commission v. Google (Google Shopping), Case AT.39740

Facts

The European Commission found that Google had favoured its comparison-shopping service in its general search results while demoting competing comparison-shopping services.

Competition issue

The matter concerned:

• search dominance;
• ranking;
• self-preferencing;
• platform design.

Institutional significance

The case demonstrates that competitive harm can result from algorithmic ranking and platform architecture, rather than traditional price discrimination alone.

Future institutional lesson

Authorities require:

• algorithmic expertise;
• ranking-system analysis;
• data scientists;
• technical audit capabilities.

4. Google Android, Case AT.40099

The European Commission examined Google's practices concerning the Android ecosystem, including arrangements involving:

• Google Search;
• Google Play;
• Android devices;
• mobile applications.

Institutional significance

The case demonstrates the importance of examining ecosystem leverage.

A competition authority may have to investigate how power in one layer of a digital ecosystem affects competition in another.

Future lesson

Institutional design should permit:

cross-market + cross-platform + ecosystem analysis.

5. European Commission v. Intel, Case C-413/14 P

Facts

The case concerned Intel's conduct involving rebates offered to computer manufacturers and a major retailer.

The Court of Justice addressed the circumstances in which the Commission must examine the ability of rebates to foreclose an equally efficient competitor.

Institutional significance

The case demonstrates the importance of combining:

• legal analysis;
• economic analysis;
• evidence assessment; and
• effects-based reasoning.

Future institutional lesson

Competition authorities require strong economic-analysis divisions capable of conducting sophisticated effects assessments.

6. Intel v. Commission, Case C-240/22 P

The later Intel litigation further demonstrates the importance of institutional competence in economic assessment and judicial review.

Significance

Complex competition cases may require authorities to:

• identify the relevant economic mechanism;
• assess evidence carefully;
• conduct appropriate economic analysis;
• provide sufficiently reasoned decisions.

Future lesson

Greater institutional expertise must be accompanied by high-quality procedural safeguards.

A technologically sophisticated authority still has to satisfy legal standards of reasoning, evidence and due process.

7. Commission v. United Brands, Case 27/76

Facts

United Brands was found to have abused a dominant position through conduct involving the banana market.

The case is a foundational authority on:

• dominance;
• relevant market;
• unfair trading conditions;
• discriminatory practices.

Institutional significance

The case represents the traditional competition-authority model based upon market definition and dominance.

Future lesson

Future institutional design should not abandon traditional competition principles.

Instead, it should combine:

traditional competition economics + digital economics + technological expertise.

8. Bronner, Case C-7/97

Facts

The case concerned access to a newspaper home-delivery system and the circumstances under which refusal of access to infrastructure could constitute an abuse of dominance.

Institutional significance

The case illustrates the difficulty of determining when access to an infrastructure controlled by a dominant undertaking must be granted.

Future relevance

The issue becomes particularly significant for:

• cloud infrastructure;
• app stores;
• payment systems;
• digital identity;
• telecommunications infrastructure;
• data-access systems.

Future authorities therefore need specialised expertise in essential facilities and interoperability.

XIII. Lessons From the Case Law

The cases collectively reveal several institutional requirements.

XIV. Data and Digital Evidence

Future competition investigations will increasingly depend upon electronic evidence.

Authorities may need to examine:

• source code;
• APIs;
• server logs;
• algorithmic outputs;
• internal datasets;
• communications;
• metadata;
• pricing records;
• recommendation systems.

Accordingly, competition authorities should establish digital forensic laboratories.

These laboratories could preserve evidence while maintaining:

• confidentiality;
• cybersecurity;
• chain of custody;
• procedural fairness.

XV. Algorithmic Collusion and Institutional Design

Algorithms create a particularly difficult enforcement problem.

Suppose competing firms use automated pricing systems that independently adjust prices.

The authority must determine whether the outcome results from:

1. lawful independent adaptation;
2. conscious coordination;
3. information exchange;
4. algorithmic implementation of an agreement; or
5. autonomous parallel conduct.

This requires cooperation among:

• lawyers;
• economists;
• programmers;
• statisticians;
• data scientists.

The future competition authority therefore becomes partly a multidisciplinary technological institution.

XVI. Procedural Safeguards

Greater investigative powers should be accompanied by stronger safeguards.

Important protections include:

• notice of allegations;
• access to evidence;
• confidentiality protection;
• privilege;
• opportunity to respond;
• reasoned decisions;
• independent adjudication;
• judicial review;
• proportional penalties.

Institutional effectiveness cannot substitute for due process.

XVII. Remedies and Institutional Design

Future remedies may extend beyond conventional fines.

Possible remedies include:

Structural remedies

• divestiture;
• separation of business units.

Behavioural remedies

• non-discrimination;
• prohibition of self-preferencing;
• fair-access requirements.

Technical remedies

• interoperability;
• data portability;
• API access;
• switching mechanisms.

Governance remedies

• compliance monitoring;
• independent trustees;
• periodic reporting.

The authority must therefore possess post-decision monitoring capacity.

XVIII. Competition Authorities as Continuous Regulators

A major institutional development may be the movement from:

one-time enforcement

towards:

continuous competition supervision

For example, after imposing an interoperability remedy, an authority may need to monitor whether the undertaking:

• technically implements the remedy;
• provides effective access;
• avoids discriminatory treatment;
• changes APIs to defeat the remedy.

Thus, enforcement does not necessarily end when the formal decision is issued.

XIX. Institutional Accountability

A powerful competition authority requires mechanisms of accountability.

These may include:

Judicial review

Courts review:

• legality;
• evidence;
• reasoning;
• proportionality.

Parliamentary oversight

Parliamentary institutions may review:

• budgets;
• institutional performance;
• statutory implementation.

Transparency

Authorities can publish:

• enforcement priorities;
• guidelines;
• market studies;
• decisions;
• annual reports.

Internal governance

Authorities should establish:

• ethics rules;
• conflict-of-interest procedures;
• data-governance policies;
• internal review mechanisms.

XX. Future Institutional Architecture

A possible future competition authority could be structured as follows:

                 COMPETITION AUTHORITY                         │       ┌─────────────────┼─────────────────┐       │                 │                 │ Enforcement        Economics        Technology Division           Division         Division       │                 │                 │ Cartels            Market Design     AI/Algorithms Dominance          Econometrics      Data Science Mergers            Effects Analysis  Digital Forensics       │                 │                 │       └─────────────────┼─────────────────┘                         │                 Digital Markets Unit                         │          ┌──────────────┼──────────────┐          │              │              │       Platforms        Data           AI          │              │              │          └──────────────┼──────────────┘                         │                International Unit                         │                Remedy Monitoring

This model combines legal, economic, technological and institutional expertise.

XXI. Future Institutional Models

Model 1: Traditional Competition Authority

Characteristics:

• ex post enforcement;
• generalist investigators;
• conventional economic analysis;
• merger control.

Limitation

May struggle with rapidly evolving technological ecosystems.

Model 2: Digital Competition Authority

Characteristics:

• specialised digital unit;
• algorithmic expertise;
• data scientists;
• platform regulation.

Limitation

Potential overlap with general competition authorities.

Model 3: Integrated Competition and Digital Regulator

This model combines:

• competition law;
• digital regulation;
• market monitoring;
• technical supervision.

Advantage

Provides a unified institutional response to systemic digital-market problems.

Challenge

Requires careful safeguards against excessive concentration of regulatory power.

Model 4: Networked Regulatory Model

Under this model, several institutions retain their separate responsibilities but cooperate closely.

Competition Authority        │        ├── Data Regulator        │        ├── Telecom Regulator        │        ├── Financial Regulator        │        ├── Consumer Authority        │        └── Cyber/Technology Authority

This model may be particularly useful where digital competition overlaps with multiple regulatory regimes.

XXII. Future Challenges

1. Regulatory overlap

Multiple authorities may investigate the same conduct.

2. Institutional fragmentation

Different regulators may reach inconsistent conclusions.

3. Technological complexity

Authorities may lack sufficiently qualified personnel.

4. Resource asymmetry

Large technology companies may have substantially greater technical resources than regulators.

5. Cross-border enforcement

Evidence and companies may be located across jurisdictions.

6. Rapid technological change

Law and institutional procedures may become outdated quickly.

7. Remedy implementation

Competition authorities may struggle to monitor technically complex remedies.

XXIII. Recommended Principles for Future Institutional Design

A modern competition authority should be based on the following principles:

1. Independence

Protection from inappropriate external influence.

2. Multidisciplinary expertise

Lawyers, economists, technologists, data scientists and industry specialists should work together.

3. Technological capability

Authorities must understand the technologies they regulate.

4. Data-driven enforcement

Large datasets should be used to detect competition risks.

5. International cooperation

Cross-border competition requires institutional coordination.

6. Procedural fairness

Enhanced investigative power must remain subject to due process.

7. Continuous monitoring

Systemic markets may require ongoing oversight.

8. Regulatory coordination

Competition authorities should coordinate with sectoral regulators.

9. Remedy capability

Authorities should have the resources to monitor and enforce remedies.

10. Adaptability

Institutional structures should be capable of responding to emerging technologies without requiring complete legislative redesign for every technological development.

Conclusion

The future institutional design of competition authorities is likely to move beyond the traditional model of a relatively generalist agency investigating conventional antitrust violations. Digitalisation, artificial intelligence, platform ecosystems, data concentration and algorithmic decision-making require competition institutions with greater technological, economic, investigative and international capabilities.

The case law from Microsoft, Google Shopping, Google Android, Intel, United Brands and Bronner, among others, demonstrates the evolution from conventional market-power analysis toward increasingly complex questions concerning technology, exclusion, ecosystem leverage, access, economic effects and institutional competence.

The central institutional challenge is therefore not simply to create larger competition authorities. It is to create authorities that are independent, technologically capable, economically sophisticated, procedurally fair, internationally coordinated and capable of continuous market monitoring.
