Price Squeeze (Margin Squeeze)

Concepts, Elements, Tests, Proof, and Application in Turkish Competition Law

Summary

Price squeezing occurs when an undertaking operating in two vertically related markets and holding a dominant position in the upstream market (input/access) sets its wholesale access price high and its retail price in the downstream market (final product) low, thereby narrowing the margin between the two prices to the point where an equally efficient competitor cannot operate sustainably. This behavior is considered an abuse of dominant position under Article 6 of Law No. 4054. The violation is a unique type of exclusionary abuse, distinct from predatory pricing and denial of access. The investigation is essentially based on cost-based tests , margin adequacy , and exclusionary effects assessment.

1. Introduction: Why is Price Squeezing Important?

Network industries (telecommunications, energy, postal services), infrastructure-based service markets, and increasingly digital platform ecosystems are vulnerable to price squeezing. This is because in these areas, an undertaking can control both the input layer (e.g., API/access, data, network, infrastructure, distribution channel) and offer the final product in the downstream market based on the same input . This vertically integrated structure leads to competitors becoming dependent on that input. Deliberate margin reduction creates a crowding-out effect; competitors either cannot enter the market at all or are forced out due to permanent losses. Even if consumer welfare initially appears to increase due to lower prices, in the medium to long term, competition decreases; freedom of choice and innovation weaken.

2. Legal Basis and Scope

Article 6 of Law No. 4054 on the Protection of Competitionprohibits the abuse of dominant position. The violations listed as examples in the article are not exhaustive; therefore, price squeezing the numerus apertus types of qualified abuse. The analysis is essentially based on the following three pillars:

Dominant position (upper market): The market power of an undertaking that controls the relevant input or access.
Vertical relationship: Functional dependence between the input in the upstream market and the final product in the downstream market.
Insufficient margin and crowding-out effect: The wholesale-retail price difference is insufficient to cover the costs of an equally efficient competitor, leading to exclusion in the sub-market.

Detection of a breach does not necessarily actual exclusion (e.g., competitor bankruptcy); potential exclusion is also considered sufficient. This is because a permanent reduction in margin weakens entry/stay incentives.

3. Conceptual Framework and Elements

3.1. Definition

Price squeeze is when the difference between the wholesale access price (W) and the retail price (R) is insufficient to cover the inevitable costs of an equally efficient competitor wishing to operate in the undermarket . In simpler terms, at the formula level:

Margin = R – W
Suspected breach: Margin < Downstream costs (D-Cost)

Downstream costs here are the unit costs that are unavoidable in the sub-market and that an efficient player will incur (e.g., marketing, customer service, billing, distribution, software licenses, payment infrastructure, return processes).

3.2. Elements

(i) Vertical relationship: The same undertaking both supplies the wholesale input and markets the retail product.
(ii) Dominant position (upper market): No alternative access to input or no economically viable alternatives. Barriers to entry are high; network and data impacts are strong.
(iii) Insufficient margin: Keeping the wholesale price level high + keeping the retail price low, or a combination of both.
(iv) Crowding-out effect: The inability of an equally efficient competitor to operate sustainably and profitably.
(v) Causality: The source of exclusion is margin politics.
(vi) Lack of objective justification: If the regulation cannot be explained by unavoidable reasons arising from quality, capacity or efficiency.

4. Identification of the Relevant Market and Dominant Position

4.1. Market Definition

The upstream market generally refers to the “access/input” market: wholesale-level infrastructure usage, API access to datasets, content/world map licensing, payment gateway, app store deployment, etc.
The downstream market encompasses the final product/service built using this input: retail internet service, navigation app, super in-app service, end-user offering at the SaaS layer, etc.

4.2. Dominant Position Criteria

High and sustained market share
Network effects, economies of scale, multilateral market structure
Monopolistic control (de facto or contractual) over input/access
Information advantage (cost, demand, user data) thanks to vertical integration
Transition costs and lock-in effects

Dominant position determination the upstream market ; market share in the downstream market alone is not a determining factor. However, the integrated undertaking's position in the downstream market is important in crowding-out effect analysis.

5. Economic Tests and Measurements

5.1. Equivalently Efficient Operator (EEO) Standard

The EEO approach makes a comparison based on the dominant undertaking's own costs : "Could a competitor with the same efficiency as the dominant undertaking operate sustainably with that margin?" This approach provides comparability , especially in markets where data and network impacts are significant

5.2. Reasonably Effective Competitor (REO) Standard

In some markets, the dominant undertaking may be very large; it is not realistic for new entrants to reach the same cost level in the short term. In such cases, a reasonable/realistic competitor . The aim is to see if entry is completely deterred .

5.3. Cost Criteria

The following cost concepts are frequently used in practice:

AAC (Average Awkward Cost): Fixed unavoidable costs spread across units.
LRAIC/LRIC (Long-Term Increasing Average/Increasing Cost): The increasing costs required to continue operations over the long term.
SAC/ATC (Total Average Cost): Average of all costs divided by units (with a stricter threshold).

Test logic:

If R – W < AAC/LRAIC, there is a strong indication that the margin insufficient and exclusionary.
R-W is sufficient, the suspicion of violation is weakened; however, the combined effect of other exclusionary factors (discount structures, binding, self-preferencing) is also examined.

5.4. Simple Numerical Example

Wholesale access fee (W): 60 units
Retail price (R): 95 units
Downstream unavoidable unit cost (D-Cost, LRAIC approach): 40 units . Margin = 95 – 60 = 35. Since 35 < 40 , an equally efficient competitor cannot operate in the sub-market; sustainable profitability is not possible. Suspicion of price squeeze strengthens.

5.5. Advanced Topics

Interaction with discount and loyalty programs: Even if the list price seems reasonable at the wholesale level, the effective net price may be increasing due to discount and refund mechanisms. Tests real payment flows.
Internal transfer pricing: If an integrated undertaking's internal transfer pricing serves to artificially keep retail prices in the sub-market low, margin narrowing can become chronic.
Subsidies in multi-party markets: If a platform subsidizes one party while making wholesale access expensive on the other, the combined effect can translate into margin squeezing.

6. Proof, Evidence, and Analytical Approach

6.1. Sources of Evidence

Contracts, wholesale access rates, additional protocols
Invoice, discount, refund, target bonus, bundle/additional service fees
Internal correspondence and pricing presentations
Customer-dealer agreements, exclusivity or target terms
Data access logs, API rate limits, SLA violations
Comparative market data (domestic/international)

6.2. Econometric and Accounting Analysis

Margin adequacy analysis: Periodic and product-based R&D comparison.
Cost allocation: Based on appropriate cost drivers; without arbitrary loading.
Sensitivity tests: Demand shocks, scale changes, variations in discounts.
Counterfactual fiction: "If the margin were reasonable, how would entry/stay be?"

6.3. Exclusionary Effect and Causality

The burden of proof must be supported by concrete facts: indicators such as competitors being unable to enter/withdrawing, capacity reduction, customer shifts, inability to submit bids, unsustainable loss reports, and inability to access financing the causal link.

7. Distinguishing from Other Types of Abuse

Predatory pricing: The final price below cost . In price squeezing, however, the price in the sub-market may remain above cost; the source of the violation a narrow margin.
Denial of access: Wholesale access is either not granted at all or is effectively blocked under unreasonable conditions. Access exists, but it is not economically meaningful.
Differentiated treatment/discrimination: Different prices/terms for competitors; discrimination in margin tightening is not mandatory, general policy can also be used.
Self-preferencing: The visibility/ranking advantage is a different category of violation; however, when combined with margin compression, a compound exclusion effect.

8. Defenses and Objective Justifications

Cost increases and capacity constraints: If wholesale price increases stem from basic input costs and are reflected transparently, margin reduction may be considered legitimate.
Quality/brand investments: a low price in the sub-market is promotional and short-lived , but creates increased efficiency and quality that is reflected in the consumer experience, it can be considered a balancing factor.
Compliance requirements and regulation: The mandatory nature of the conduct may be debatable if regulator-defined minimum/maximum tariffs or costs under universal service obligations exist
Productivity gains: Measurable productivity justifications (economies of scale, scope, technology investment) that increase net consumer welfare in the short to medium term can be put forward; however, this is difficult to excuse the systematic and persistent underestimation of the margin.

9. Sanctions and Private Law Consequences

Administrative fine: Determined based on turnover, depending on the severity, duration, and impact of the violation, within the framework of Law No. 4054
Behavioral/repricing measures: Adjustment of wholesale and retail prices and conditions, transparency of discounts, ring-fencing, and reporting obligations.
Contractual adjustments: Reasoning the terms of access, establishing a fair, reasonable and non-discriminatory (FRAND-like) framework.
Private law compensation: Businesses harmed by an infringement damages ; the calculation of damages takes into account lost profits, price inflation, loss of market share, brand erosion, and financing costs.

10. Compliance Perspective: A Roadmap for Companies

10.1. Early Warning Indicators

Frequent and unilateral increases
Aggressive reductions in retail prices; ongoing promotional campaigns
Anomalous subsidy to sub-unit in internal transfer pricing.
Competitors' inability to effectively access return/discount conditions
Quotas/SLAs that appear equal in API/infrastructure access, but create asymmetry in practice

10.2. Internal Control and Tests

R-W margin checklist: Monthly margin tables and automated alert thresholds by product.
Cost matching: Keeping unavoidable costs in the sub-market current and auditable.
Discount-refund transparency: Centralized reporting of effective net price.
Ring-fencing: Procedures that restrict internal information flow; economic independence between sub-market units and wholesale units.
Independent audit: Annual competition compliance audits and “margin squeeze risk report”

10.3. Contract Design Proposals

Transparent pricing formulas and update mechanisms.
Writing measurable and auditable access-quality metrics (SLAs)
Objective criteria for discounts and target bonuses.
Compliance with the principle of equality in data access and technical requirements.
Dispute resolution clause: expedited interim solution (appointment of expert, mini-arbitration)

11. Price Squeezing in Digital Markets and Platform Economies

11.1. Data and API Access

If a platform prices its data/access API as wholesale input and then uses that same data to deliver a final service to the end user, the margin between wholesale and retail prices must be such that it does not exclude independent developers/partners operating in the sub-market . Otherwise, while nominal access may appear to exist, economic access becomes virtually impossible.

11.2. Application Stores and Distribution

store commissions, technical requirements, visibility/ranking advantages, and bundled service fees are considered together, the true wholesale cost and the final price can narrow. Therefore, margin testing effective revenue after commission .

11.3. “Freemium” and Cross-Subsidying

Setting a price in the sub-market either free of charge or symbolically is not always exclusionary; however, keeping wholesale access expensive in parallel and maintaining this policy for a long time prevents competitors from catching up to scale. A careful distinction must be made between short-term promotion and systematic margin reduction .
