Predatory pricing is a dominant firm pricing below cost to eliminate rivals and recoup later: below average variable/avoidable cost is presumed abusive (AKZO), between AVC and average total cost it is abusive with exclusionary intent, and US law adds a strict recoupment requirement (Brooke Group). Margin squeeze is its vertical cousin: a dominant input supplier leaving downstream rivals too little space between wholesale and retail prices to compete — an independent abuse in the EU and Türkiye, but not in the US.
Predatory pricing and margin squeeze are the pricing abuses — the doctrines that decide when low prices, the thing competition law exists to encourage, become the instrument of its destruction. Because false positives here punish discounting itself, the tests are the most economically structured in the field, and the transatlantic divergence is the widest. This guide covers both doctrines with the AKZO, Brooke Group, Deutsche Telekom and TeliaSonera lines — part of the dominance pillar of our Competition & Antitrust hub.
What is the AKZO test?
Prices below average variable cost are presumed predatory (no rational purpose but exclusion); prices between AVC and average total cost are predatory only with evidence of an exclusionary plan. Modern practice often substitutes average avoidable cost (AAC) and long-run average incremental cost (LRAIC) as benchmarks.
Why does the US almost never condemn predation?
Brooke Group requires below-cost pricing plus a dangerous probability of recoupment — proving the predator can later raise prices long enough to recover losses. Courts treat discounting as presumptively procompetitive, and hardly any claim survives.
What is the margin-squeeze test?
Whether an as-efficient downstream competitor could trade profitably paying the dominant firm’s wholesale price and matching its retail price. If the spread is insufficient, the squeeze is abusive in the EU/Türkiye regardless of whether either price is independently abusive.
What makes low pricing an abuse at all?
The sacrifice-and-recoupment logic: a dominant firm accepts avoidable losses today because eliminating or disciplining rivals buys pricing power tomorrow. Competition loses twice — the rival exits, and prices later exceed what sustained competition would have produced. The doctrinal difficulty is separating this from penetration pricing, promotional pricing, and efficient firms simply being cheaper — all procompetitive, all superficially similar.
Hence the cost-based architecture. Pricing above total cost is essentially never abusive; the fight lives below, where cost benchmarks proxy for rationality: no equally efficient rival can survive prices below the incumbent’s own avoidable cost, so such prices are read as exclusion unless explained. The ‘as-efficient competitor’ (AEC) principle anchors the whole field — competition law protects rivals as efficient as the dominant firm, not every rival — and after Intel, effects-capability analysis on these lines governs pricing abuses generally, as our abuse overview explains.
How does the EU’s AKZO framework operate in practice?
Three bands. Below AVC/AAC: presumption of abuse — the firm loses money on each incremental sale, and the burden shifts to it to show objective justification (fire-sale of perishables, launch promotions bounded in time and scope). Between AVC and ATC: abuse where part of a plan to eliminate — proved by documents (the strategy deck targeting the entrant), selectivity (cuts aimed only at the rival’s customers), timing and duration. Above ATC: lawful, essentially conclusively.
Two refinements carry modern weight. Cost-allocation fights decide multi-product cases: which costs are incremental to the contested product determines the band, and defendants win or lose in the accounting. Selective low pricing — matching the entrant’s price only where it competes, funded from monopoly territories — has been condemned even near cost (Post Danmark I softened this with an effects focus; the doctrine remains). Notably, the EU does not require recoupment proof: dominance itself implies the structure for later recovery, the Court has held — the sharpest formal divergence from US law.
AKZO, dominant in organic peroxides, responded to small rival ECS’s expansion by targeting ECS’s flour-additive customers with prices below cost while holding higher prices elsewhere — documented in internal threats to eliminate ECS if it did not retreat. The Court’s judgment built the enduring two-benchmark test (AVC presumption, AVC-ATC plus intent) and condemned the selectivity of the campaign. Thirty-five years on, every predation matter in the EU and Türkiye — from telecoms entrants to bus wars — still opens with the AKZO bands, updated with AAC/LRAIC benchmarks for network industries.
Why is US predation law so different?
Brooke Group (1993) set the two cumulative requirements: pricing below an appropriate measure of cost and a dangerous probability of recouping the investment in below-cost prices. The second prong is deliberately hard: plaintiffs must show market structure permitting supra-competitive pricing after the campaign — entry barriers, capacity discipline, oligopoly cohesion — and courts have treated most markets as too porous for recoupment.
The policy is explicit: the Supreme Court judged false condemnations of discounting costlier than missed predation, betting that unsustainable predation self-corrects. Critics answer that modern platform economics — deep pockets, network effects, winner-take-most tipping — make recoupment structural rather than speculative, and that the doctrine under-deters below-cost growth strategies in digital markets. The academic fight has practical stakes for global businesses: an aggressive price campaign lawful under Brooke Group can be an AKZO abuse in Europe and Türkiye on the same facts — pricing strategy needs regime-by-regime clearance, not a single global sign-off.
How does margin squeeze work as a standalone abuse?
The setting: a vertically integrated firm dominates an upstream input (network access, wholesale capacity, a platform’s core service) and competes downstream against its own wholesale customers. The squeeze: setting the wholesale-retail spread so thin that an as-efficient downstream rival cannot profitably serve customers — whether by pricing wholesale high, retail low, or both.
Deutsche Telekom and TeliaSonera established its independence in EU law: the squeeze itself is the abuse — no need to show the wholesale price is excessive or the retail price predatory, and (TeliaSonera) no need for the input to be an indispensable facility. The test is the AEC spread analysis run on the incumbent’s own downstream cost structure. US law rejected the doctrine in linkLine (2009): absent an antitrust duty to deal at wholesale, there is no duty to leave rivals a margin — squeeze claims must be repackaged as predation and fail with it. Türkiye follows the EU: the Board has run squeeze analyses in telecoms, ports and platform matters, and regulated-sector incumbents (energy, telecoms) face parallel sectoral-regulator price tests.
What defences and justifications actually work?
A short but real list. Meeting competition: matching (not undercutting) a rival’s price in good faith, proportionately and temporarily — recognised in principle, policed for pretext. Objective commercial logic: clearing perishable or obsolete stock, bounded launch promotions, network-industry ramp-up pricing toward LRAIC over a defensible horizon. Cost defence: the fight over benchmarks and allocation — demonstrating the contested prices in fact cover avoidable costs properly measured.
What fails: efficiency rhetoric unsupported by numbers, ‘the rival is inefficient anyway’ (the AEC test protects hypothetical equal efficiency, and Post Danmark II reminds that even less-efficient rivals may matter in structures where scale is the barrier), and any defence contradicted by contemporaneous documents. The defence file, as always, is built before the conduct: pricing committees that record the commercial rationale, cost coverage and duration limits of aggressive campaigns convert litigation risk into an evidence package.
Where do these doctrines bite in modern markets?
Telecoms and network industries remain squeeze territory — regulated wholesale access plus retail competition is the classic geometry, and Turkish, EU and UK regulators run standing AEC tests on incumbents. Platform economics revived predation debates in new clothing: below-cost delivery pricing in quick-commerce and ride-hailing, zero-fee strategies funded by adjacent monopolies, and ecosystem cross-subsidies all raise AKZO-style questions that the EU and Türkiye’s platform investigations have begun to test; loyalty pricing and retroactive rebate structures — predation’s cousin — are treated in our rebates guide.
Retail wars supply steady national caseloads (supermarket price campaigns against discounter entry), and state-aid-adjacent sectors add a twist: subsidised incumbents pricing below cost engage both competition and subsidy-control rules — the EU’s Foreign Subsidies Regulation now polices exactly this pattern for non-EU-funded bidders. The common operational thread: pricing aggression by any firm with a dominant position anywhere in its structure needs a legal-economic pre-check, because the line between winning and infringing is an accounting exercise conducted, if you are unlucky, by the authority.
What is the recoupment debate really about?
Error costs. Requiring recoupment proof (US) minimises false condemnations of discounting but assumes markets punish failed predators — an assumption platform economics strains, since network effects can make a predation campaign self-recouping through tipping rather than later price rises. Dispensing with recoupment (EU) trusts cost-based screens plus dominance to filter, accepting occasional chilling of aggression as the lesser evil.
The synthesis emerging in scholarship and cautious enforcement: treat recoupment not as a separate hurdle but as part of the coherence check — a predation story that could never pay should meet skepticism anywhere, while structures where exclusion plausibly self-finances (tipping markets, multi-market discipline, reputation predation across geographies) justify intervention without a demonstrated future price rise. Practitioners should brief both framings: cross-border pricing campaigns are judged under both simultaneously.
How do damages claims follow pricing-abuse findings?
Two claimant classes with opposite theories: excluded rivals claim the profits the squeeze or predation destroyed — business-valuation exercises comparing actual trajectories against but-for entry scenarios — while customers claim the later recoupment-phase overcharge where prices rose after exclusion. Telecoms squeeze findings across Europe generated substantial rival claims; Turkish follow-on litigation is younger but growing on the Board’s decisions.
The evidentiary interplay rewards planning on both sides: the authority’s AEC computations become the claimant’s damages skeleton, and defendants’ own justification files double as mitigation evidence. For victims, preservation matters from the first suspicious quarter — margin records, lost-tender documentation and financing costs of surviving the squeeze are the exhibits that convert doctrine into recovery.
Frequently Asked Questions
Is loss-leading by supermarkets predatory pricing?
Rarely under competition law — most grocers lack dominance, and loss-leaders are bounded promotions. Several countries (including sectoral rules in Türkiye and below-cost resale bans in France and Belgium) regulate it through unfair-trading laws instead, a separate regime.
Can a non-dominant firm ever commit pricing abuse?
Not under Article 102/Article 6 — dominance is the gateway. But sector rules (below-cost resale bans), unfair-competition statutes and state-aid rules can reach similar conduct by non-dominant firms; predation analysis also appears inside merger reviews of aggressive acquirers.
How is ‘cost’ measured for multi-product platforms?
By incremental and avoidable cost of the contested activity — the allocation of shared costs (logistics, technology, marketing) is where these cases are won and lost, and where regulators demand granular internal accounting most firms cannot produce quickly.
Does margin squeeze require the rival to actually exit?
No — capability of foreclosing an as-efficient competitor suffices in the EU/Türkiye; actual exit strengthens the effects picture and the damages claims that follow. Deutsche Telekom was condemned while rivals survived, shrunken.
