Competition Law and Future Institutional Architectures for Competition Governance

1. Introduction

Competition law is traditionally organised around a relatively simple institutional model:

Legislature → Competition Authority → Courts → Market Participants

The future economy is likely to make this architecture considerably more complex. Digital platforms, artificial intelligence, algorithmic pricing, autonomous agents, cloud infrastructure, data ecosystems, app stores, interoperability systems and cross-border digital markets can create competitive problems that do not fit neatly within conventional enforcement institutions.

Future competition governance therefore requires an institutional architecture, rather than merely stronger substantive rules.

The central question is not only:

“What conduct should competition law prohibit?”

but also:

“Which institution should detect, investigate, regulate, remedy, monitor and adjudicate that conduct?”

Modern case law already demonstrates why institutional design matters. Courts have had to address two-sided markets, loyalty rebates, technological ecosystems, essential facilities, self-preferencing and platform power.

2. Meaning of Institutional Architecture in Competition Governance

Institutional architecture refers to the allocation and coordination of competition-governance functions among:

1. legislatures;
2. competition authorities;
3. sector regulators;
4. digital-market regulators;
5. data-protection authorities;
6. consumer-protection agencies;
7. courts and specialist tribunals;
8. technical and economic expert bodies;
9. international competition networks; and
10. private enforcement mechanisms.

A future competition system therefore becomes a multi-level governance structure.

Traditional model

Parliament
↓
Competition Authority
↓
Investigation
↓
Decision
↓
Appeal Court

Emerging model

Legislature / International Rules
↓
Competition Authority + Digital Regulator + Sector Regulator + Data Authority
↓
Technical/Economic Investigation
↓
Administrative Decision / Interim Measures
↓
Specialist Tribunal or Court
↓
Remedy + Compliance Monitoring
↓
Continuous Market Review

This represents a movement from event-based enforcement toward continuous competition governance.

3. Why Future Institutional Architecture Is Necessary

A. Digital markets operate across jurisdictions

A platform may:

• be incorporated in one country;
• host infrastructure in another;
• process data in several jurisdictions;
• have consumers globally; and
• engage in conduct affecting several competition authorities simultaneously.

Consequently, national enforcement alone may produce:

• inconsistent decisions;
• conflicting remedies;
• duplicated investigations;
• regulatory gaps; and
• forum shopping.

Future institutions therefore require stronger mechanisms for international coordination.

4. From Ex Post Enforcement to Ex Ante Governance

Traditional competition law is largely ex post.

The authority waits for:

1. conduct;
2. complaint;
3. investigation;
4. infringement finding; and
5. remedy.

Digital markets increasingly require ex ante intervention.

The institutional model may therefore become:

Market surveillance → Risk identification → Designation of significant firms → Conduct obligations → Continuous monitoring → Enforcement

The European Union's Digital Markets Act illustrates this movement by imposing specified obligations on designated gatekeepers alongside traditional competition-law enforcement.

This does not eliminate Article 101/102 TFEU-type enforcement. Instead, it creates a parallel regulatory layer.

5. Competition Authorities as Continuous Market Supervisors

Future competition authorities may increasingly perform five functions.

1. Investigation

Investigating:

• cartels;
• exclusionary conduct;
• acquisitions;
• self-preferencing;
• discriminatory access;
• tying;
• interoperability restrictions;
• algorithmic coordination.

2. Market intelligence

Authorities may continuously monitor:

• market shares;
• switching rates;
• interoperability;
• data concentration;
• algorithmic behaviour;
• acquisition patterns;
• platform dependency.

3. Technical auditing

Future authorities may need technical teams capable of examining:

• source code;
• AI models;
• recommender systems;
• ranking algorithms;
• APIs;
• data flows;
• cloud architecture.

4. Remedy supervision

An authority may have to determine whether a remedy actually works rather than simply issue an infringement decision.

5. Anticipatory intervention

Authorities may intervene before competitive harm becomes irreversible.

6. Separation of Institutional Functions

A major future principle should be functional separation.

An institution that:

• investigates,
• prosecutes,
• decides,
• imposes penalties,
• supervises remedies, and
• controls market access

may accumulate considerable power.

Future competition architecture should therefore provide procedural safeguards.

A possible structure is:

Investigation Division
↓
Independent Decision-Making Panel
↓
Specialist Appeal Tribunal
↓
Judicial Review

This can improve:

• impartiality;
• transparency;
• accountability;
• evidentiary discipline; and
• procedural fairness.

7. Competition Authority–Sector Regulator Coordination

Many future competition problems will occur in regulated industries.

Examples include:

• telecommunications;
• banking;
• energy;
• aviation;
• healthcare;
• digital payments;
• transport;
• cloud infrastructure.

A competition authority may possess expertise concerning market power, while the sector regulator possesses technical expertise.

Therefore, institutional architecture should provide:

Joint jurisdiction

Both regulators may investigate different dimensions of the same conduct.

Coordinated investigation

Information can be shared subject to confidentiality safeguards.

Lead-agency rules

Legislation can identify which regulator takes primary responsibility.

Joint remedies

A competition authority may address exclusion while the sector regulator establishes technical access conditions.

8. Data Authorities and Competition Authorities

Data has become an important competitive asset.

A dominant undertaking may possess:

• extensive consumer data;
• transaction data;
• behavioural information;
• search data;
• location information;
• interoperability information.

Competition authorities therefore increasingly need coordination with data-protection authorities.

However, data protection and competition law have different objectives.

Future architecture should avoid collapsing the two regimes into one.

Instead:

Competition Authority + Data Authority + Consumer Authority

should coordinate while retaining their separate statutory purposes.

9. Algorithmic Competition Governance

Artificial intelligence creates a particularly difficult institutional problem.

Algorithms can:

• set prices;
• rank competitors;
• allocate customers;
• personalise offers;
• detect rivals;
• optimise inventory;
• coordinate supply;
• determine access.

A future competition authority therefore requires an algorithmic competition unit.

It could contain:

• economists;
• competition lawyers;
• computer scientists;
• data scientists;
• AI specialists;
• forensic investigators.

Possible institutional process

Algorithmic signal detected
↓
Technical audit
↓
Economic analysis
↓
Competition investigation
↓
Human decision-maker
↓
Judicial review

The critical principle is that algorithmic evidence should not be treated as self-explanatory.

10. Autonomous Agents and Future Competition Governance

The problem becomes more complicated where AI agents negotiate independently.

Imagine competing firms using autonomous agents that:

• monitor competitors;
• alter prices;
• negotiate contracts;
• purchase inventory;
• respond to market conditions.

The institutional question becomes:

Who is legally responsible for machine-mediated coordination?

Future competition institutions may need rules concerning:

1. attribution;
2. human supervision;
3. auditability;
4. logging;
5. explainability;
6. preservation of algorithmic evidence;
7. responsibility for autonomous decisions.

Competition authorities will consequently require technical powers that conventional antitrust agencies were not designed to exercise.

11. Merger Review as Continuous Institutional Governance

Traditional merger control focuses on a transaction.

Future merger governance may need to examine acquisition patterns.

A large platform may acquire:

• startups;
• potential competitors;
• data companies;
• AI developers;
• infrastructure providers.

Each individual acquisition may appear relatively small, while the cumulative effect may significantly increase ecosystem power.

Future institutions may therefore develop:

Acquisition-pattern monitoring

Authority → Monitor acquisitions → Identify cumulative concentration → Investigate strategic accumulation

This is particularly important in:

• AI;
• biotechnology;
• cloud computing;
• digital advertising;
• fintech;
• data infrastructure.

12. Case Law

Case 1: United States v. Microsoft Corp. — Institutional Lessons from Technology Markets

Court: U.S. Court of Appeals for the D.C. Circuit
Year: 2001

Microsoft demonstrates the difficulty of applying conventional antitrust institutions to rapidly evolving technology markets.

The litigation concerned Microsoft's conduct concerning operating systems and web browsers. The appellate proceedings illustrate the importance of judicial review of complex technological and economic findings.

Institutional significance

The case demonstrates the need for:

• technically competent investigators;
• economically sophisticated evidence;
• carefully structured remedies;
• judicial oversight; and
• institutional capacity to understand technological ecosystems.

It supports the proposition that technology competition cannot be governed effectively through purely formal legal analysis.

13. Case 2: Ohio v. American Express Co.

U.S. Supreme Court, 2018

This case is particularly important for future institutional design because the Court treated the credit-card system as a two-sided transaction platform.

The Court held that both sides—cardholders and merchants—had to be considered in analysing the competitive effects of the challenged antisteering provisions.

Institutional lesson

Competition authorities cannot always investigate a platform as though it were a conventional one-sided market.

Future institutional architecture therefore requires:

• platform economists;
• two-sided-market expertise;
• network-effects analysis;
• cross-market evidence collection.

A regulator examining only merchant prices, for example, could miss effects occurring on the consumer side.

14. Case 3: Intel Corp. v. European Commission

CJEU, Case C-413/14 P, 2017

The Court of Justice set aside the General Court's judgment concerning Intel's loyalty rebates and required further examination of whether the rebates were capable of foreclosing competitors.

Institutional significance

Intel illustrates the importance of economically rigorous enforcement.

A future competition authority must possess the institutional ability to conduct:

• effects analysis;
• foreclosure analysis;
• counterfactual assessment;
• economic modelling;
• evidence-based market analysis.

Thus, institutional competence becomes part of substantive enforcement quality.

15. Case 4: FTC v. Qualcomm

U.S. Court of Appeals for the Ninth Circuit, 2020

The FTC alleged that Qualcomm used anticompetitive practices to maintain monopoly positions in modem-chip markets. The Ninth Circuit reversed the district court's judgment and rejected the FTC's theory under the applicable antitrust framework.

Institutional lesson

Qualcomm demonstrates the importance of clearly defining:

• the theory of harm;
• the relevant competitive process;
• the relationship between exclusion and competition;
• the appropriate remedial jurisdiction.

It also illustrates why competition agencies need strong appellate and judicial engagement with technical industries.

16. Case 5: Google Shopping — Google LLC and Alphabet Inc. v European Commission

CJEU, Case C-48/22 P, 2024

The Court of Justice upheld the European Commission's infringement finding concerning Google's favouring of its own comparison-shopping service and maintained the €2.4 billion fine.

Institutional significance

The case is important for the future governance of platform ecosystems.

Self-preferencing requires an authority to understand:

• ranking systems;
• search architecture;
• platform incentives;
• visibility;
• traffic allocation;
• foreclosure mechanisms.

Traditional competition authorities therefore need technological and economic capacity comparable to the firms they regulate.

17. Case 6: Slovak Telekom v European Commission

CJEU, Case C-165/19 P, 2021

The case concerned access to telecommunications infrastructure, conditions of access and margin squeeze under Article 102 TFEU.

Institutional lesson

Infrastructure-dependent competition frequently requires coordination between:

• competition authorities;
• telecommunications regulators;
• infrastructure operators;
• technical experts.

Future institutional architecture should therefore accommodate regulated-access competition problems rather than treating every dispute as a conventional antitrust case.

18. Case 7: Google Shopping as a Model for Hybrid Governance

Google Shopping also illustrates a broader institutional transformation.

Traditional competition law asks:

Did the dominant firm abuse its position?

Future digital governance increasingly asks:

What institutional mechanism should prevent the platform from repeatedly exploiting its structural position?

This distinction explains the growing importance of combining:

ex post antitrust + ex ante digital regulation + technical monitoring.

19. Future Institutional Architecture

A comprehensive future model could be represented as follows:

                 LEGISLATURE                     │          Competition Framework                     │        ┌────────────┴────────────┐        │                         │ Competition Authority      Sector Regulators        │                         │        ├─────────────┬───────────┤        │             │           │ Digital Unit     Economic Unit  Data/AI Unit        │             │           │        └─────────────┼───────────┘                      │             Market Intelligence                      │              Investigation                      │            Decision-Making Body                      │              Remedies/Orders                      │          Compliance Monitoring                      │             Specialist Tribunal                      │                 Higher Court

20. The Multi-Agency Competition Council

One possible future model is a Competition Governance Council.

It could coordinate:

• competition authority;
• digital regulator;
• telecommunications regulator;
• financial regulator;
• consumer authority;
• data-protection authority;
• AI regulator;
• energy regulator.

The Council need not replace existing agencies.

Instead, it could provide:

1. information sharing;
2. jurisdiction allocation;
3. joint investigations;
4. regulatory consistency;
5. emerging-market surveillance;
6. coordinated remedies.

21. International Competition Governance

Global digital firms create a further institutional challenge.

Future competition governance may increasingly operate through:

National level

National competition authorities.

Regional level

Regional competition institutions.

International level

Cooperation among competition authorities through networks and multilateral frameworks.

A future architecture could therefore look like:

National Authority ↔ Regional Authority ↔ International Competition Network

The objective would be greater:

• evidence sharing;
• procedural cooperation;
• convergence of analytical methods;
• coordinated merger review;
• coordinated remedies.

22. Regulatory Sandboxes

Future competition authorities may also use competition sandboxes.

A sandbox could allow regulators to observe emerging markets before imposing permanent rules.

Potential fields include:

• AI marketplaces;
• autonomous commerce;
• blockchain infrastructure;
• digital payments;
• energy platforms;
• cloud ecosystems;
• mobility platforms.

The institutional advantage is that regulators can learn from market development instead of regulating entirely through assumptions.

23. Competition Impact Assessments

Before adopting major digital or economic regulations, governments could conduct a Competition Impact Assessment.

It could examine:

• barriers to entry;
• concentration;
• interoperability;
• switching costs;
• access to data;
• network effects;
• vertical integration;
• platform dependency.

This would transform competition policy from an enforcement mechanism into a whole-of-government policy discipline.

24. Independent Technical Expertise

Future competition authorities should not depend exclusively upon evidence supplied by investigated firms.

They may require:

Independent laboratories

For technical testing.

Algorithmic audit teams

For AI and pricing systems.

Economic modelling units

For market simulations.

Digital forensic units

For electronic evidence.

Data science teams

For large-scale market monitoring.

This creates a model of institutional technological parity between regulators and regulated firms.

25. Judicial Architecture

Future competition systems also require specialised judicial capacity.

Complex competition litigation can involve:

• econometrics;
• algorithms;
• network effects;
• intellectual property;
• data;
• cybersecurity;
• technical standards.

Courts therefore need:

• specialist judges;
• economic experts;
• technology experts;
• expedited procedures for urgent digital cases.

However, expert assistance should support rather than replace judicial decision-making.

26. Remedies as an Institutional Function

Future competition authorities will increasingly need to supervise remedies over time.

Potential remedies include:

Structural remedies

• divestiture;
• separation;
• business-unit separation.

Behavioural remedies

• non-discrimination;
• interoperability;
• access obligations;
• prohibition of tying.

Technical remedies

• API access;
• data portability;
• interoperability;
• ranking transparency.

Monitoring remedies

• independent compliance monitors;
• periodic reporting;
• algorithmic audits.

The institution therefore moves from:

“Find violation → impose penalty”

to:

“Find violation → design remedy → monitor remedy → reassess market → modify remedy where legally permitted.”

27. Due Process in Future Competition Institutions

Greater regulatory power requires stronger procedural safeguards.

Important safeguards include:

1. notice of allegations;
2. access to evidence;
3. confidentiality protection;
4. opportunity to respond;
5. independent decision-makers;
6. reasoned decisions;
7. judicial review;
8. proportionality;
9. protection against arbitrary intervention.

The more technically complex the regulatory system becomes, the more important these safeguards become.

28. Key Principles of Future Institutional Architecture

Future competition governance can be built around ten principles:

1. Independence

Competition authorities should operate independently from political and commercial pressure.

2. Technical competence

Authorities need technological expertise.

3. Economic competence

Complex markets require sophisticated economic analysis.

4. Institutional coordination

Competition law cannot operate in isolation from sector regulation.

5. International cooperation

Cross-border markets require cross-border enforcement mechanisms.

6. Ex ante capacity

Authorities should be capable of addressing foreseeable structural risks.

7. Ex post enforcement

Traditional antitrust enforcement remains essential.

8. Remedy supervision

Competition governance should extend beyond the initial infringement decision.

9. Procedural fairness

Greater institutional power requires greater accountability.

10. Adaptability

Institutions must be capable of responding to technological change.

29. Challenges

A. Regulatory overlap

Multiple regulators may claim jurisdiction.

B. Institutional conflict

Competition objectives may conflict with sector-specific objectives.

C. Regulatory capture

Highly concentrated industries may possess substantial resources for influencing regulatory processes.

D. Technological asymmetry

Private firms may possess more technical knowledge than regulators.

E. International inconsistency

Different jurisdictions may impose conflicting obligations.

F. Over-enforcement

Excessively interventionist institutions could potentially discourage legitimate innovation.

G. Under-enforcement

Insufficient institutional capacity could allow dominant ecosystems to become entrenched.

The appropriate architecture therefore requires effective enforcement together with procedural discipline and institutional accountability.

30. Future Model: From Competition Authority to Competition Governance System

The most important transformation can be represented as:

Old model

Competition Authority → Investigation → Infringement → Penalty

Emerging model

Market Intelligence
↓
Competition Surveillance
↓
Economic + Technical Investigation
↓
Competition Authority
↕
Sector/Data/Digital Regulators
↓
Decision
↓
Remedy
↓
Continuous Monitoring
↓
Judicial Review
↓
International Coordination

This is a movement from competition enforcement toward competition governance.

31. Conclusion

The future of competition law will depend not merely upon expanding the list of prohibited practices, but upon constructing institutions capable of understanding and governing increasingly complex economic systems.

The cases of Microsoft, American Express, Intel, Qualcomm, Google Shopping and Slovak Telekom demonstrate different dimensions of this institutional challenge: technological ecosystems, two-sided markets, economic effects analysis, technologically complex infrastructure, self-preferencing and access-dependent competition.

The future architecture is therefore likely to be multi-level, multidisciplinary, technologically capable, internationally coordinated and continuously supervisory.

The central institutional shift can be stated simply:

Future competition law will increasingly require not one competition authority acting alone, but an interconnected governance architecture capable of detecting, analysing, remedying and continuously monitoring competitive risks across digital, physical and autonomous markets.
