Vertical restraints vs horizontal agreements: RPM and territories

Answer B. The critical question is who agreed to divide territories. Atlas did not impose the restriction; the independent dealers did. An agreement among horizontal competitors to allocate markets is typically treated as a per se antitrust violation, so the dealers' bilateral pact is likely unlawful even though the manufacturer had assigned primary regions.

Why not A: Tempting because vertical restraints created by a manufacturer are commonly judged under the rule of reason; however, that analysis applies to manufacturer-imposed vertical restraints. Here the dealers themselves made an independent agreement, horizontal conduct that is treated differently (often per se unlawful).

Why not C: Tempting because manufacturers can lawfully allocate territories to distributors, but that fact does not immunize a separate agreement among competing dealers. A horizontal agreement to divide markets remains illegal even if it mirrors a manufacturer's territorial scheme.

Why not D: Tempting because many antitrust analyses focus on competitive effects, but per se treatment for horizontal market allocation does not require proof of actual price increases or reduced output, the agreement among competitors is the primary wrongdoing once correctly classified.

Answer D. The most important factor is how the restraint is classified: a territorial division between horizontal competitors is generally treated as a per se unlawful market-allocation agreement. The stem expressly rules out mergers, joint ventures, or other integrations that might convert the restraint into an ancillary one, so the characterization of the agreement as a horizontal allocation controls the analysis. Claimed efficiencies or the existence of other sellers do not typically save a naked horizontal allocation.

Why not A: Market alternatives can matter in some contexts, but the question's facts present a naked territorial division between direct competitors; that classification, as a horizontal market allocation, remains the dominant legal factor even if other sellers exist.

Why not B: This is tempting because students often think efficiencies can justify restraints. But for a naked horizontal market-allocation agreement, claimed efficiency gains usually do not override the per se condemnation; the classification of the restraint is the controlling issue here.

Why not C: A written contract can make evidence easier to prove, which makes this attractive as a distractor. However, antitrust liability depends on the substance of the agreement (the competitive effect and the type of restraint), not whether it was memorialized in writing.

Answer B. M1 and M2 are horizontal competitors who reached an agreement to allocate geographic markets; such agreements are treated as classic per se violations of Section 1 of the Sherman Act. The fact that each firm implemented the allocation by imposing territorial limits on its dealers does not alter the horizontal character of the competitors' agreement. A different analysis (for example, rule of reason) could apply only if the parties formed a legitimate, integrated joint venture or merged.

Why not A: This is tempting because unilateral vertical territorial restraints often receive rule-of-reason treatment, but the key fact here is a direct agreement between horizontal competitors to divide territories, which invokes per se Section 1 treatment.

Why not C: This distractor confuses monopolization doctrine (Section 2), where monopoly power is central, with Section 1 concerted-action rules; a per se horizontal market-allocation agreement does not require proof of monopoly power.

Why not D: Efficiency arguments may be relevant in a rule-of-reason analysis, but they do not create an exemption for classic per se horizontal market-allocation agreements, particularly given the stated absence of merger or integrated joint venture here.

Answer B. Conversations among competitors about expected future prices and timing of increases create significant antitrust risk because they facilitate unlawful coordination. The appropriate protective action is to object to participation, leave immediately, and promptly document and report the incident so counsel or compliance can preserve evidence and advise the company. The manager's lack of final pricing authority does not remove the risk, passive presence or commentary can be used to infer participation.

Why not A: Tempting because it relies on the idea that liability requires an express agreement or authority; wrong because mere attendance or silence while competitors discuss future pricing creates legal and inference risks and fails to protect Apex or preserve evidence.

Why not C: Tempting as a cautious middle ground, but incorrect: the risk arises as soon as future pricing is discussed, waiting for a formal agreement allows coordination to occur and misses the obligation to withdraw and promptly document/report.

Why not D: Tempting because historical pricing seems less risky, but incorrect: exchanging pricing information with competitors can itself raise antitrust concerns, and once discussion turns to future prices the proper action is to decline participation, leave, and report.

Answer A. This is a horizontal agreement between competitors to divide customers and to coordinate minimum bid margins. Under Section 1 of the Sherman Act, horizontal customer allocation and horizontal price-fixing are classic per se violations, the government need not prove monopoly power or perform a detailed rule-of-reason balancing to establish illegality. Remaining separate entities or lack of dominant market share does not immunize such conduct.

Why not B: Tempting because questions about market power and measurable harm are central to Section 2 and to rule-of-reason cases; however, per se Section 1 violations (like horizontal price-fixing and customer allocation) do not require proof of monopoly power or dominance to be unlawful.

Why not C: Tempting because a limited or partial allocation and independence of firms can suggest a rule-of-reason inquiry; but courts treat core horizontal agreements to allocate customers or fix prices as per se illegal regardless of whether the allocation is partial or the firms stay separate.

Why not D: Tempting because efficiencies and ancillary-restraint arguments are common defenses, but they rarely save hard-core horizontal restraints; for an ancillary defense to apply, the restraint must be subordinate and necessary to a broader, legitimate collaboration, facts not present here for a straightforward customer allocation and price coordination agreement.

Answer B. Alpha and Beta are horizontal competitors who agreed to divide customers and not solicit each other's existing or prospective clients. Agreements among horizontal competitors to allocate customers or markets are treated as per se violations of Section 1 of the Sherman Act, so the absence of price-fixing or a joint venture does not make this arrangement lawful.

Why not A: Tempting because students often associate 'per se' primarily with price-fixing, so no price agreement suggests rule-of-reason treatment; wrong because per se categories also include horizontal customer- or market-allocation agreements, which are unlawful irrespective of whether prices were fixed.

Why not C: Tempting because the firms remain independent and set their own prices, which can look like a nonintegrated distribution arrangement; wrong because vertical restrictions occur between firms at different market levels (e.g., manufacturer and distributor), whereas Alpha and Beta are direct competitors (horizontal), so the vertical-analysis framing is incorrect.

Why not D: Tempting because monopoly power is central to some antitrust claims, which can confuse students; wrong because Section 1 prohibits concerted anticompetitive agreements among competitors (like customer allocation) without requiring proof that one party has monopoly power under Section 2.

Answer A. This describes a horizontal agreement among competitors to set a minimum selling price, which is classic horizontal price-fixing and is treated as a per se federal antitrust violation. Because it is a competitor-level price-fixing agreement, the government generally does not need detailed proof of market power or actual competitive effect to establish liability. The other choices involve vertical or unilateral conduct that are typically judged under the rule of reason or require a different legal showing.

Why not B: Tempting because it involves resale pricing, but this is a vertical agreement between manufacturer and dealer; under current precedent vertical minimum resale-price arrangements are generally evaluated under the rule of reason rather than treated as per se unlawful.

Why not C: An exclusive territorial grant is a vertical, nonprice distribution restraint; absent additional facts showing substantial anticompetitive effect, it is normally evaluated under the rule of reason rather than automatically condemned.

Why not D: This may look coercive, but the stem states Alpha acted unilaterally. Unilateral conduct without a concerted agreement typically does not constitute the Section 1 price‑fixing violation that triggers per se treatment; different legal theories (and usually a showing of market power) are required to challenge a unilateral refusal to deal.

Answer D. A unilateral announcement and a subsequent refusal to deal normally do not by themselves establish the concerted agreement required for Sherman Act Section 1; they are typically treated as unilateral conduct. By contrast, conditioning continued supply on the retailer's assent and receiving that assent is strong evidence of a vertical agreement that can be challenged under Section 1. Also, minimum resale price maintenance is not per se illegal under current federal law and is generally analyzed under the rule of reason, so the threshold issue here is whether an agreement exists.

Why not A: This is tempting because candidates sometimes overextend the unilateral-refusal-to-deal principle. It is wrong here because SoundWave's interaction with Retailer B went beyond a mere announcement and refusal to deal: SoundWave conditioned supply on Retailer B's agreement and obtained that agreement, which supports Section 1 scrutiny.

Why not B: This is tempting because monopoly power is central to Section 2 monopolization claims. It is wrong because Section 1 liability for agreements restraining trade does not require proof that the defendant possesses monopoly power, although market power can matter in a full rule-of-reason analysis.

Why not C: This distractor appeals to those who recall older per se treatment of minimum RPM. It is incorrect under current federal law because vertical minimum resale price restraints are analyzed under the rule of reason rather than being per se illegal, so the existence of an agreement is the key threshold question.
