Competition Law and Long-Term Ecosystem Resilience and Competition Law

1. Introduction

Long-term ecosystem resilience in competition law refers to the ability of a market or commercial ecosystem to remain competitive, contestable, innovative and adaptable over time, even when individual firms become very large or technological and economic conditions change significantly.

Modern ecosystems may contain:

digital platforms;

AI systems;

cloud infrastructure;

payment networks;

online marketplaces;

app stores;

logistics systems;

telecommunications;

financial technology;

data infrastructure;

supply chains.

A resilient competitive ecosystem should be capable of absorbing:

technological disruption;

business failure;

new entrants;

changes in consumer preferences;

supply shocks;

innovation;

regulatory changes.

The basic principle is:

Competition law should not merely preserve competition at one point in time; it should preserve the conditions that allow competition to regenerate in the future.

2. Meaning of Ecosystem Resilience

In competition law, ecosystem resilience can be understood as the capacity of a market structure to maintain competitive alternatives despite changes in technology, firms, infrastructure and consumer behaviour.

A resilient market generally has:

multiple suppliers;

meaningful entry opportunities;

low or manageable switching costs;

innovation;

alternative technologies;

access to essential inputs;

independent competitors;

diversified supply chains.

A fragile market may have:

one dominant platform;

strong network effects;

high switching costs;

concentrated data;

few suppliers;

limited interoperability;

significant barriers to entry.

3. Why Resilience Matters to Competition Law

Traditional competition law often asks:

“Is competition being harmed now?”

A resilience-oriented approach additionally asks:

“Will competition remain capable of recovering and developing in the future?”

This is important because a market may appear competitive today but become structurally dependent on one firm tomorrow.

For example:

Platform dominance → data accumulation → stronger AI → greater user attraction → more data → greater dominance.

Once this feedback loop becomes entrenched, restoring competition may become difficult.

4. Main Objectives

Long-term ecosystem resilience requires protection of:

1. Contestability

New competitors must have realistic opportunities to enter.

2. Diversity of supply

The market should not become unnecessarily dependent upon one supplier.

3. Innovation

Alternative technologies should be able to develop.

4. Interoperability

Different systems should be capable of interacting where appropriate.

5. Data mobility

Data should not unnecessarily create permanent lock-in.

6. Consumer choice

Consumers should retain meaningful alternatives.

7. Business-user independence

Businesses should not become unreasonably dependent on a single platform.

8. Infrastructure diversity

Critical inputs should not become unnecessarily concentrated.

5. Resilience Is Not the Same as Maximum Competition

Competition law should not attempt to create an artificially fragmented economy.

Large firms can produce legitimate benefits through:

economies of scale;

research and development;

infrastructure investment;

lower costs;

technological innovation.

Therefore:

Resilience does not mean eliminating large firms.

It means preventing market structures or conduct that unnecessarily destroy the competitive alternatives needed for future rivalry.

6. Static Competition vs Dynamic Competition

Static competition

Focuses on:

current prices;

current market shares;

current output;

current consumer effects.

Dynamic competition

Focuses on:

innovation;

future competitors;

technology;

investment;

entry;

market evolution.

Ecosystem resilience primarily concerns dynamic competition.

7. Network Effects

Network effects are central to ecosystem resilience.

Example:

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

This can create a powerful feedback mechanism.

Network effects can generate efficiency, but they may also make entry difficult.

Competition authorities should therefore examine whether network effects are:

natural;

contestable;

strengthened by exclusionary conduct;

combined with high switching costs.

8. Data Concentration

Data can reinforce market power.

A dominant platform may possess:

customer data;

transaction data;

search information;

location information;

supplier data;

behavioural information.

This data may improve:

algorithms;

AI models;

recommendations;

pricing;

advertising.

The resulting feedback loop can weaken resilience:

More users → more data → better technology → more users.

9. Interoperability

Interoperability is an important resilience mechanism.

If competing systems can communicate:

System A ↔ System B ↔ System C

users can switch more easily.

Without interoperability:

System A → closed ecosystem

may become increasingly difficult to challenge.

Competition policy may therefore consider interoperability where appropriate, particularly in markets characterized by network effects and strong switching costs.

10. Data Portability

Data portability can facilitate competition.

A consumer or business might move relevant data from:

Platform A → Platform B

instead of rebuilding its entire commercial history.

This can reduce:

switching costs;

customer lock-in;

entry barriers.

11. Multi-Homing

Multi-homing occurs when users participate in several competing ecosystems.

Example:

A seller uses:

Marketplace A;

Marketplace B;

Marketplace C.

This reduces dependence upon a single platform.

Long-term competition policy should therefore examine contractual or technical restrictions that unnecessarily prevent multi-homing.

12. Supply-Chain Resilience and Competition

Competition and supply-chain resilience are related but not identical.

A concentrated supply chain can create:

supply disruption;

bargaining dependency;

higher switching costs;

vulnerability to shocks.

Competition policy should therefore consider whether concentration results from:

efficiency

or

exclusionary strategies that eliminate alternative suppliers.

13. Essential Infrastructure

Some ecosystems depend upon infrastructure such as:

telecommunications;

cloud computing;

payment networks;

app stores;

digital identity;

logistics;

energy networks.

Where infrastructure is genuinely indispensable and the applicable legal test is satisfied, access issues may become important.

But competition law should not automatically require sharing of every commercially valuable asset.

14. Ecosystem Lock-In

Lock-in occurs when leaving a platform becomes difficult.

Sources include:

incompatible data;

proprietary technology;

contractual restrictions;

loss of accumulated information;

high switching costs;

loss of network benefits.

Long-term resilience requires asking:

Can a successful ecosystem still be challenged by an alternative ecosystem?

15. Self-Preferencing

An ecosystem may simultaneously operate:

infrastructure; and

competing commercial services.

For example:

Marketplace + marketplace-owned products.

If the platform uses its control over ranking or visibility to systematically favour its own products, competition may be affected.

The Google Shopping proceedings provide an important example of this type of competition issue.

16. Vertical Integration

Large ecosystems may integrate:

Cloud → AI → Operating System → Marketplace → Payment → Logistics.

Vertical integration can generate efficiency.

However, it can also create opportunities for:

foreclosure;

tying;

discriminatory access;

self-preferencing;

raising rivals' costs.

Long-term resilience analysis should therefore examine the competitive effects of integration rather than treating integration as automatically unlawful.

17. Merger Control and Ecosystem Resilience

Merger control is one of the most important tools for preserving future resilience.

Authorities should examine acquisitions involving:

startups;

potential competitors;

emerging technology;

AI;

data;

infrastructure.

A small startup may have little current market share but substantial future competitive significance.

18. Killer Acquisitions

A dominant ecosystem may acquire a startup before it becomes a meaningful competitor.

The acquisition may eliminate:

future innovation;

alternative technology;

future price competition;

an independent ecosystem.

Therefore, long-term merger analysis can ask:

Would the target have developed into a significant competitive constraint if it had remained independent?

19. Innovation Resilience

A resilient ecosystem should allow competing technologies to develop.

Competition policy can therefore consider:

R&D;

patents;

technological alternatives;

startups;

research pipelines;

innovation incentives.

A market with many firms but little innovation may not be genuinely resilient.

20. AI and Ecosystem Resilience

AI may intensify ecosystem concentration.

Important inputs include:

computing power;

chips;

cloud services;

data;

specialized talent.

A company controlling several of these inputs may obtain substantial competitive advantages.

Potential concerns include:

Compute concentration → AI concentration → distribution concentration → ecosystem concentration.

21. Algorithmic Competition

Algorithms can:

determine prices;

rank products;

recommend services;

allocate advertising;

select suppliers.

Algorithms may increase efficiency but can also facilitate:

coordination;

discrimination;

exclusion;

self-preferencing.

The use of an algorithm alone does not establish an antitrust violation.

Authorities must establish the relevant legal elements and competitive effects.

22. Important Case Laws

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

Facts

Microsoft had substantial power in the PC operating-system market. The litigation concerned exclusionary conduct involving Internet Explorer and competing technologies.

Principle

The case examined conduct that protected Microsoft's position and restricted competitive threats.

Relevance to Ecosystem Resilience

The case demonstrates how dominance over one technological layer can affect competition in adjacent markets.

The resilience lesson is:

Competition can become fragile when one undertaking controls a foundational technological layer and can use that position to restrict emerging alternatives.

23. United Brands Co. v Commission, Case 27/76

Principle

United Brands is a foundational European authority concerning:

dominance;

relevant markets;

market power;

abusive conduct.

Resilience Relevance

Before determining whether an ecosystem is competitively fragile, authorities must identify whether an undertaking possesses substantial market power.

Market power analysis remains fundamental even in highly technological markets.

24. AKZO Chemie BV v Commission, Case C-62/86

Principle

AKZO is an important authority concerning predatory pricing by dominant undertakings.

Resilience Relevance

A dominant ecosystem could potentially use aggressive pricing to eliminate smaller competitors.

If competing firms disappear because of exclusionary pricing, ecosystem resilience may decline.

The case therefore illustrates the importance of protecting competitors from unlawful exclusionary pricing while permitting legitimate price competition.

25. Bronner v Mediaprint, Case C-7/97

Principle

Bronner addressed refusal of access to a distribution system and established important limits concerning compulsory access.

Resilience Relevance

A resilient ecosystem may require access to genuinely indispensable infrastructure.

But the case also emphasizes that competition law does not automatically require dominant undertakings to share every asset.

The applicable legal conditions must be satisfied.

26. Ohio v. American Express Co., 585 U.S. 529 (2018)

Facts

American Express operated a two-sided transaction platform connecting merchants and cardholders.

Principle

The Supreme Court considered the interdependence between the two sides of the platform when evaluating competitive effects.

Resilience Relevance

Modern ecosystems can contain multiple interdependent groups.

For example:

Consumers ↔ Platform ↔ Sellers ↔ Advertisers ↔ Payment providers.

A resilience assessment must therefore consider the ecosystem as an interconnected structure.

27. MOTOE v Elliniko Dimosio, Case C-49/07

Principle

The case concerned an entity that exercised regulatory powers while also participating in an economic activity.

Resilience Relevance

It illustrates the competition concern that can arise when an entity:

establishes market rules;

controls access;

and competes within the same market.

For ecosystem resilience, independent governance is important where the platform effectively acts as both referee and competitor.

28. Google Shopping Proceedings

Competition Issue

The Google Shopping proceedings concerned treatment of Google's comparison-shopping service within its search ecosystem.

Principle

The proceedings are important for understanding self-preferencing and the relationship between a dominant infrastructure provider and competing services.

Resilience Relevance

If a platform controls the route through which consumers discover products, discriminatory ranking can affect whether competing businesses remain viable.

29. Google Android — Case AT.40099

Principle

The Android proceedings concerned Google's contractual arrangements relating to Android devices and associated services.

Resilience Relevance

The case illustrates how power in one ecosystem layer can potentially be used to influence competition in adjacent layers.

This is relevant to:

operating systems;

app stores;

search;

AI assistants;

digital services.

30. Lessons From the Cases

These authorities arise under different legal frameworks. They therefore provide comparative principles rather than a single universal resilience test.

31. Long-Term Ecosystem Resilience Framework

A competition authority can examine resilience through ten questions.

Question 1 — Concentration

How concentrated is the market?

Question 2 — Entry

Can new firms enter?

Question 3 — Switching

Can users leave?

Question 4 — Multi-Homing

Can users use multiple platforms?

Question 5 — Data

Is essential competitive data concentrated?

Question 6 — Infrastructure

Are critical inputs controlled by a small number of firms?

Question 7 — Innovation

Can alternative technologies develop?

Question 8 — Acquisitions

Are future competitors being acquired?

Question 9 — Interoperability

Can competing systems communicate?

Question 10 — Recovery

If a dominant firm fails or becomes inefficient, can competitors replace it?

32. Competition Resilience Indicators

A long-term competition authority can monitor:

Market concentration

High concentration may warrant closer examination, although concentration alone does not establish illegality.

Entry rate

Are new competitors entering?

Exit rate

Are competitors disappearing?

Switching costs

How difficult is it to leave?

Innovation

Are new technologies emerging?

Investment

Are firms investing in alternative infrastructure?

Acquisition activity

Are incumbents purchasing emerging competitors?

Interoperability

Can different systems interact?

Data concentration

Is valuable information controlled by one undertaking?

33. Ex-Ante Regulation

Traditional competition law often works retrospectively.

However, in highly concentrated digital ecosystems, certain legal systems have introduced ex-ante obligations.

The EU Digital Markets Act is a prominent example.

It establishes obligations for designated gatekeepers concerning matters including:

interoperability;

data;

self-preferencing;

business-user relationships;

switching and choice.

This approach reflects the idea that some digital markets may become difficult to restore after competitive conditions deteriorate.

34. Ex-Post Competition Enforcement

Ex-post enforcement remains important for:

cartels;

abuse of dominance;

exclusionary conduct;

anti-competitive agreements;

mergers.

A resilience-oriented framework therefore combines:

Ex-ante safeguards + Ex-post enforcement.

35. Structural Resilience

Structural resilience concerns the underlying market architecture.

Questions include:

How many independent suppliers exist?

Are alternative infrastructures available?

Are firms dependent upon one platform?

Are there independent distribution channels?

Can competitors access necessary inputs?

Structural resilience is particularly important in:

telecommunications;

cloud computing;

payment systems;

energy;

logistics;

digital marketplaces.

36. Behavioural Resilience

Behavioural resilience concerns how firms act.

Authorities may monitor:

exclusive agreements;

discriminatory access;

self-preferencing;

tying;

bundling;

predatory pricing;

refusal to deal.

A market may have several firms but remain fragile if one firm can impose restrictive conditions on everyone else.

37. Consumer Resilience

Consumers should not become permanently dependent upon one ecosystem.

Important factors include:

switching;

portability;

alternative suppliers;

transparent conditions;

interoperability.

Consumer resilience means consumers can respond to:

price increases;

quality deterioration;

privacy concerns;

service failures.

by moving to alternatives.

38. Business Resilience

Businesses should also have alternatives.

For example:

Seller → Marketplace A

should ideally not become:

Seller → Marketplace A → complete dependency.

A resilient commercial ecosystem permits businesses to:

diversify platforms;

use multiple suppliers;

move data;

access alternative infrastructure.

39. Infrastructure Resilience

Critical infrastructure can become a competition bottleneck.

Examples:

cloud computing;

payment systems;

telecom networks;

app distribution;

logistics infrastructure.

Competition policy should consider whether alternative infrastructure exists and whether competitors can realistically develop it.

40. Resilience and Public Policy

Governments may support strategic industries for reasons such as:

national security;

technological development;

economic stability;

infrastructure development.

However, public support should not unnecessarily eliminate competitive alternatives.

A resilient competition policy therefore seeks a balance between:

Strategic capability

and

Competitive openness.

41. International Competition

Large ecosystems operate across borders.

A platform may have:

users in one jurisdiction;

servers in another;

developers elsewhere;

suppliers worldwide.

International cooperation may therefore be required for:

merger control;

digital investigations;

information exchange;

remedies;

market studies.

42. Competition Resilience and Crisis

Suppose a dominant cloud provider experiences a major outage.

If all businesses depend upon that provider, the economic consequences may be substantial.

A resilient ecosystem might contain:

multiple cloud providers;

interoperable systems;

portable data;

alternative infrastructure.

Competition law cannot solve every resilience problem, but maintaining competitive alternatives can contribute to economic resilience.

43. Practical Example

Assume MegaPlatform controls:

AI services;

cloud computing;

online marketplace;

payments;

logistics.

It has acquired several small AI startups.

Its marketplace ranking system gives preferential placement to its own products.

Its contracts restrict sellers from using rival logistics providers.

Businesses find it expensive to move their data elsewhere.

A long-term resilience analysis would ask:

Is MegaPlatform dominant?

Are sellers dependent upon it?

Are alternative marketplaces viable?

Can sellers multi-home?

Does self-preferencing disadvantage competitors?

Do exclusive logistics arrangements foreclose rivals?

Have acquisitions eliminated potential competitors?

Can businesses transfer their data?

Is alternative cloud infrastructure available?

Would competition recover if MegaPlatform stopped serving the market?

This last question is particularly important:

Can the market regenerate competitive alternatives?

44. Remedies Supporting Resilience

Possible remedies, depending on applicable law, include:

1. Interoperability

Allow competing systems to communicate.

2. Data portability

Reduce switching costs.

3. Non-discrimination

Prevent unjustified discriminatory treatment.

4. Access remedies

Provide appropriate access to indispensable infrastructure where legal requirements are satisfied.

5. Merger remedies

Protect future competitive constraints.

6. Structural remedies

Use separation or divestiture where legally justified and behavioural remedies are inadequate.

7. Monitoring

Continue supervision after a remedy is imposed.

45. Risks of Overemphasizing Resilience

Resilience should not become a justification for protecting every inefficient competitor.

Potential problems include:

preserving inefficient firms;

preventing economies of scale;

discouraging investment;

excessive regulation;

reduced innovation.

Therefore:

Competition resilience should preserve competitive process, not guarantee the survival of individual competitors.

46. Risks of Underemphasizing Resilience

If competition authorities focus only on current prices, they may miss:

future monopoly;

startup acquisitions;

data lock-in;

infrastructure dependence;

ecosystem tipping;

declining innovation.

A market can have low prices today and still become less competitive tomorrow.

47. Long-Term Policy Model

A practical policy sequence is:

Step 1 — Map the ecosystem

Identify platforms, suppliers, infrastructure and users.

Step 2 — Measure market power

Assess concentration, entry barriers and network effects.

Step 3 — Identify dependencies

Determine who depends upon whom.

Step 4 — Examine conduct

Analyse:

exclusivity;

self-preferencing;

tying;

pricing;

interoperability restrictions.

Step 5 — Examine future competition

Consider:

startups;

innovation;

potential substitutes;

acquisitions.

Step 6 — Assess resilience

Ask whether competitive alternatives can survive and develop.

Step 7 — Select proportionate remedies

Use the least restrictive effective intervention consistent with the applicable law.

Step 8 — Monitor continuously

Markets evolve, so resilience should be reassessed periodically.

48. Key Legal Principles

Ecosystem resilience is not the same as market fragmentation.

Large firms are not automatically unlawful.

Dominance is not automatically abuse.

Competition law should protect competitive processes rather than individual competitors.

Network effects can make markets less contestable.

Data concentration can reinforce market power.

Interoperability can reduce lock-in.

Portability can facilitate switching.

Self-preferencing may raise competition concerns depending on the applicable legal framework and effects.

Potential competition can be important in merger analysis.

Innovation is an important dimension of long-term competition.

Infrastructure access requires careful legal analysis.

Ex-ante and ex-post regulation can complement one another.

Remedies should be proportionate.

Competition authorities should consider whether markets can regenerate competition after disruption.

49. Conclusion

Long-term ecosystem resilience and competition law are increasingly interconnected.

A competitive ecosystem should not merely function efficiently today. It should also retain the capacity to:

attract new entrants;

develop alternative technologies;

withstand business failures;

support innovation;

permit switching;

prevent permanent lock-in;

maintain independent suppliers;

preserve future competitive pressure.

The cases of Microsoft, United Brands, AKZO, Bronner, American Express, MOTOE, Google Shopping and Google Android demonstrate different aspects of this broader problem: technological foreclosure, dominance, exclusionary pricing, infrastructure access, multi-sided platforms, regulatory power, self-preferencing and ecosystem leverage.

The central principle is:

Competition law should preserve the conditions under which competition can continue to reproduce itself over time.

Quick Revision Formula

Long-Term Ecosystem Resilience =

Contestability + Entry + Innovation + Interoperability + Data Mobility + Multi-Homing + Infrastructure Alternatives + Future Competition + Merger Review + Proportionate Remedies

One-Line Exam Definition

Long-term ecosystem resilience in competition law means maintaining market structures and competitive conditions that allow independent firms, consumers and future entrants to adapt, innovate and compete over time without unnecessary dependence upon a dominant undertaking or ecosystem.
