MEMORANDUM ORDER
PRENTICE H. MARSHALL, District Judge.
In this multidistrict litigation, plaintiff Tennessee Valley Authority (“TVA”) seeks damages from defendants Gulf Oil Corporation and Gulf Minerals Canada, Ltd. (“Gulf”) under § 1 of the Sherman Act, 15 U.S.C. § 1 (1976), which prohibits “[ejvery contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade .... ”
TVA alleges that Gulf was a member of an international uranium cartel which conspired to set the price of uranium at artificially high levels. Because TVA is a consumer of uranium, it has allegedly been forced to pay higher prices for uranium because of the existence of the cartel. TVA brings this action pursuant to § 4 of the Clayton Act, which permits “[a]ny person who shall be injured in his business or property by reason of anything forbidden in the antitrust laws” to sue for treble damages. 15 U.S.C. § 15 (1976).
TVA maintains that it was the victim of an unlawful boycott in which members of the cartel refused to bid at TVA’s invitation on contracts for the sale of uranium to TVA at anything other than artificially high, cartel-set prices in November, 1973, forcing TVA to purchase its uranium through negotiated contracts, develop its own source of supply, and incur other substantial expenses, all of which it asserts are recoverable.
Gulf has moved for partial summary judgment, arguing that TVA’s claims for damages caused by purchases at higher than competitive prices from nondefendants or entities not alleged to be members of the cartel are barred by the rule of
Illinois Brick Co. v. Illinois,
431 U.S. 720, 97 S.Ct. 2061, 52 L.Ed.2d 707 (1977). In order to rule on the motion, we must first examine the holding in
Illinois Brick.
Illinois Brick
finds its roots in the decision of the Supreme Court in
Hawaii v. Standard Oil Co.,
405 U.S. 251, 92 S.Ct. 885, 31 L.Ed.2d 184 (1972). There, the state of Hawaii sued under § 4 of the Clayton Act to recover damages to its general economy caused by antitrust violations. The Court held that the damages were not recoverable. The measure of damages in such a case would be impossibly speculative, posing insurmountable problems of proof. Moreover, allowing recovery would create an unacceptable risk of duplicative recoveries if both the state and individual antitrust plaintiffs were permitted to sue.
Five years later, the Court decided
Illinois Brick.
There the plaintiffs claimed that the antitrust defendants had charged higher than competitive prices to middlemen, who had passed on those cost increases to plaintiffs, who were the ultimate consumers. Relying on
Hawaii v. Standard Oil Co.,
the Court refused to permit such claims by indirect purchasers. The Court began by noting that, in
Hanover Shoe, Inc. v. United Shoe Machinery Corp.,
392 U.S. 481, 88 S.Ct. 2224, 20 L.Ed.2d 1231 (1968), the Court had held those who sell goods at artificially high prices in violation of the antitrust laws cannot defend an action brought by a direct purchaser on the ground that the direct purchaser passed on the overcharge to its customers. The Court had rejected this defense first because it was unwilling to complicate suits under § 4 with the difficulties inherent in attempting to trace the effects of an overcharge on the purchaser’s prices, sales, costs and profits, and second because it was unwilling to permit antitrust defendants to retain the fruits of their illegality since indirect purchasers might be less likely to sue for damages caused by overcharges.
Illinois Brick Co. v. Illinois,
431 U.S. 720, 724-25, 97 S.Ct. 2061, 2064, 52 L.Ed.2d 707 (1977). The Court then noted that consistency required that the Court either abandon
Hanover Shoe,
or permit antitrust defendants to use its rationale as a defense to suits brought by indirect purchasers, since the same difficulties are present whenever a “pass-on” theory is used, be it by the plaintiff or the defendant.
See
431 U.S. at 729-37, 97 S.Ct. at 2066-70. The Court concluded that it would follow
Hanover Shoe
and not permit actions, by indirect purchasers, in light of the risk of duplicative recovery created if both direct and indirect purchasers could sue,
see id.
at 737-41, 97 S.Ct. at 2070-72, and the difficulties of tracing overcharges through various levels in the distribution chain,
see id.
at 741-47, 97 S.Ct. at 2072-75.
Thus,
Illinois Brick
represents an attempt to avoid the type of antitrust claim likely to lead to unfair or unworkable results. Where there is no danger of those results, the rationale of
Illinois Brick
is plainly inapplicable. To evaluate claims in light of
Illinois Brick,
it is essential to examine the claim to determine whether it creates a risk of duplicative recovery or the problems associated with tracing the effects of an overcharge through the distribution chain. Where these dangers are not present,
Illinois Brick
does not operate as a bar to an antitrust claim.

In re Uranium Antitrust Litigation,

Gulf acknowledges that the actual holding of
Illinois Brick
is not applicable here, since TVA was a direct purchaser of uranium, and the problems associated with the status of indirect purchasers that the Court relied on in
Illinois Brick
are not applicable here. However, Gulf asserts that claims against nondefendants and nonmembers of the cartel pose the same difficulties that concerned the Court in
Illinois Brick,
and therefore should be barred under its rationale. In support of its position, Gulf relies on
Mid-West Paper Products Co. v. Continental Group, Inc.,
596 F.2d 573 (3d Cir.1979). There, the court held that an antitrust plaintiff may not recover overcharges from members of a cartel incurred when the plaintiff purchased goods from competitors of the cartel members. In
Mid-West,
the plaintiff argued that the defendant cartel members should be liable for the artificially high prices charged by their competitors, since the existence of the cartel created a “price umbrella” which enabled non-conspirators to charge artificially high prices. Judge Adams, writing for a divided
court,
concluded that this theory posed the same problems that were present in
Illinois Brick.
Specifically, he reasoned that it would be practically impossible to determine the effect of the cartel on the pricing policies of nonconspirators, given the wide variety of factors which influence pricing policies.
See
596 F.2d at 584. Moreover, the court concluded that
Illinois Brick
represents a judgment that the objectives of the antitrust laws are fulfilled when the defendant is required to disgorge the fruits of its illegalities. Once that occurs, there is no need to go further and force antitrust defendants to pay for overcharges of others such as nonconspirators.
See id.
at 585-86. Finally, the court noted that permitting recovery for nonconspirators’ overcharges creates a risk of ruinous recoveries, since it would create liability well in excess of the antitrust defendants’ ill-gotten gains.
See id.
at 586-87.
TVA’s initial response to Gulf’s
Illinois Brick/Mid-West Paper
argument is to claim that its complaint alleges an unlawful refusal to deal, rather than a simple case of price fixing. TVA goes on to argue that
Illinois Brick
applies only to price fixing cases, and not to boycott cases. Gulf joins the issue by arguing that this is not a boycott case,
and from there the parties proceed to engage in a semantic dispute over whether TVA’s claims should be characterized as relating to a “boycott” or “price fixing.”
In our judgment, the question of whether the complaint alleges a “boycott” or “price fixing” is entirely irrelevant to the issue at hand.
Illinois Brick
is not a case about semantics. It addresses intensely practical concerns associated with avoiding unfair or unworkable results in antitrust litigation. If the underlying policy concerns which motivated the result in
Illinois Brick
are applicable, then we believe
Illinois Brick
should be applied, regardless of the label that is attached to plaintiff’s claims.

First, we turn to Gulf’s claim that
Illinois Brick
precludes recovery for overcharges paid to cartel members not named as defendants. This claim is puzzling since Gulf seems to concede that it is liable for overcharges paid to its co-conspirators who are named as defendants. Indeed this is the case; nothing in
Illinois Brick
precludes liability for overcharges directly paid to members of a price-fixing conspiracy.

Illinois Brick
permits recovery for overcharges paid to conspiring defendants but not to conspiring nondefendants. However, Gulf never explains why anything should turn on this distinction, and cites no authority for the distinction. None of the policies underlying
Illinois Brick
are affected by whether or not the overcharge is paid to a named defendant or a non-defendant co-conspirator. To the contrary, it has long been the law that an antitrust defendant is jointly and severally liable for the acts of its co-conspirators,
see e.g., In re Uranium Antitrust Litigation,
617 F.2d 1248, 1257 (7th Cir.1980);
see also Havoco of America, Ltd. v. Shell Oil Co.,
626 F.2d 549, 554 (7th Cir.1980). Under this rule of law, Gulf is liable for any act of its co-conspirators in furtherance of the alleged price fixing conspiracy, whether or not that co-conspirator is named as a defendant.

We conclude that TV A may maintain its claims for overcharges paid to nondefen-dant co-conspirators.
Second, we turn to TVA’s claims involving overcharges paid to nondefendant nonconspirators. These are the types of claims that were addressed by the Third Circuit in
Mid-West Paper.
If we decide to follow
Mid-West
by concluding that the problems posed by attempting to prove that the prices charged by nonconspirators were inflated by the existence of the uranium cartel are insurmountable, then these claims are barred.
Mid-West
has received considerable attention from both courts and commentators. A number of courts have found its reasoning persuasive.

In light of this split of authority, we must examine the question whether
Mid-West
is a sound interpretation of
Illinois Brick.
As our earlier discussion of
Illinois Brick
indicates, a major theme underlying that opinion is the unacceptable risk of duplicative recovery created when both direct and indirect purchasers are permitted to sue under the antitrust laws. However, in this case, no risk of duplicative recovery exists. If TVA cannot recover for the overcharges it has paid nonconspirators, no one can. Far from eliminating a risk of duplicative recovery, a denial of standing in this case, assuming TVA can prove at trial that non-conspirators’ prices were affected by the existence of the cartel, “would also result in the denial of compensation for injuries resulting from unlawful conduct.”
Blue Shield of Virginia v. McCready,
- U.S. -, 102 S.Ct. 2540, 2546 n. 10, 73 L.Ed.2d 149 (1982).
In
Illinois Brick,
the court stated that by permitting a direct purchaser to recover the entire amount of overcharge, without any consideration of passing-on, the law ensures that defendants must pay for the full amount of damage they have caused, rather than permitting recovery to be depleted by litigation over pass-on issues.
See
431 U.S. at 745-57, 97 S.Ct. at 2074-80. If standing is denied here, however, a serious gap in antitrust enforcement would be created, in that antitrust defendants would not be accountable for an entire category of damages they have caused.
Denying standing to these plaintiffs leaves uncompensated an entire class of direct purchasers — the group
Illinois Brick
suggested would often be most harmed by the overcharges. Furthermore, the decision frustrates the congressional goal of deterrence by failing to hold the defendants accountable for a major portion of damages proximately caused by the conspiracy.
Illinois Brick
does not justify this result. The issue in that case was not whether the defendants should escape liability for a portion of the damages caused by the conspiracy, but rather, whether recovery should be apportioned among classes of plaintiffs.
Case Comment,
supra
note 9, at 604 (footnote omitted).
In its most recent exposition in this area, the Supreme Court, in referring to
Illinois Brick
and
Hawaii v. Standard Oil,
stated,
Both cases focused on the risk of dupli-cative recovery engendered by allowing every person along a chain of distribution to claim damages arising from a single transaction that violated the antitrust laws.
Blue Shield of Virginia v. McCready,
- U.S. -, 102 S.Ct. 2540, 2546, 73 L.Ed.2d 149 (1982). Here there is no such danger. In light of
McCready,
it is arguable that
Illinois Brick
should never be read to bar an antitrust recovery in the absence of a risk of duplicative recoveries. Whether or not
McCready
erects such a blanket prohibition, the fact that
Mid-West,
unlike
Illinois Brick,
creates a gap in antitrust enforcement is a strong argument against concluding that
Illinois Brick
justifies the rule of
Mid-West.
Even if we assume that
Illinois Brick
could bar an antitrust claim in the absence of a risk of duplicative recoveries, we still find
Mid-West’s
reasoning unpersuasive.
Mid-West
focused on the problems associated with proving what the prices of noncon-spirators would have been but for the antitrust violation. However, this calculation,
whatever the difficulties it poses, is no more problematic than determining damages in any price-fixing case. In the most pedestrian price-fixing ease, the trier of fact must calculate the price the defendants would have charged but for the conspiracy, in order to determine the measure of damages attributable to the conspiracy.
See, e.g.,
II P. Areeda & D. Turner, Antitrust Law ¶ 344a (1978). The difficulties of determining the “competitive price” that the seller would have charged in the absence of the conspiracy are not greater whether the price was charged by a conspirator or not.
In each case, the price actually charged is known. In each case, damages can only be assessed by determining what the market price would have been “but for” the price-fix. Of course in both cases, it is possible that the seller would have sold at a price above that of the market even without the price-fix and presumably the defendant would have an opportunity to present evidence of this.

530 F.Supp. at 39;
In re Mid-Atlantic Toyota Antitrust Litigation,
516 F.Supp. 1287, 1295 (D.Md.1981);
Folding Carton,
88 F.R.D. at 219. Once the “competitive” price of the nonconspirators is determined, it is not only logical but essential to infer that any price higher than that which the nonconspirators charged was the result of the cartel, since in a non-car-telized market, a seller can charge a higher than competitive price only at the risk of losing market share and profits.
See, e.g.,
R. Posner, Antitrust Law 44-47 (1976); L. Sullivan, Handbook of the Law of Antitrust § 110 at 318 (1977). In a cartelized market, the price charged by nonconspirators will be a function of the price charged by conspirators; nonconspirators will either simply take the cartel’s price as a given, or else act as oligopolists and reduce their output in order to enable the cartel to maintain its price structure.
In any event, the prices charged by the nonconspirators are the result of the existence of the cartel.

II P. Areeda & D. Turner,

See also Wall Products Co. v. National Gypsum Co.,
357 F.Supp. 832, 840 (N.D.Cal.1973).
We conclude that the
Mid-West
court’s concern with the difficulties in proving whether the price charged by nonconspira-tors is attributable to the existence of the cartel is unwarranted. Determining the “competitive price” that would have been charged by nonconspirators absent the price fixing is no more difficult than making this calculation in the run-of-the-mill antitrust case. Once it is established that nonconspi-rators have charged more than competitive prices, the inference that the cost increase was caused by the cartel is inescapable. Granted there will be some uncertainty regarding these calculations, but no more so than in any price fixing case where it is uncertain what price the defendants would have charged but for the antitrust violation. Thus, “[t]he most elementary conceptions of justice and public policy require that the wrongdoer shall bear the risk of the uncertainty which his own wrong has created.”

282 U.S. 555, 562, 51 S.Ct. 248, 250, 75 L.Ed. 544 (1931).
The other concerns expressed by the court in
Mid-West
are more easily ad
dressed. The court adverted to the unfairness of requiring defendants to do more than simply disgorge their unlawful profits, and also have to pay for profits realized by nonconspirators. However, the antitrust laws do not seek only to force defendants to disgorge profits, but also to compensate plaintiffs for injuries proximately caused by defendants’ antitrust violations, and nothing in
Illinois Brick
supports denying direct purchasers any portion of those damages which constitute compensation for the injuries to direct purchasers such as TVA proximately resulting from unlawful conduct.
See Blue Shield of Virginia v. McCready,
- U.S. -, 102 S.Ct. 2540, 2546 n. 10, 73 L.Ed.2d 149 (1982). Indeed, the existence of the treble damage remedy itself, as well as holding defendants liable for overcharges paid to co-conspirators, demonstrates that there is no congressional policy limiting antitrust damages to the amount of profit realized by an antitrust defendant as a result of its illegal activities. Finally, the antitrust laws seek to deter,
id.
and
Mid-West
results in underdeterrence, since it does not penalize defendants for the full amount of overcharge caused by their conduct; defendants will not internalize the full social costs of their actions.
The
Mid-West
court also noted that permitting liability for overcharges by noncon-spirators would lead to potentially “ruinous” liability. However, the question of what amount of liability is “ruinous” is a classically legislative judgment. Congress, in § 4 of the Clayton Act, has explicitly created an action for treble damages for any person “injured in his business or property by reason of anything forbidden in the antitrust laws .... ” Once it is established that TVA has been injured because of the existence of the cartel, it is not for this court to ignore the plain language of the statute because it might create a “ruinous” liability. The answer to this concern is found in the Court’s opinion in
Reiter v. Sonotone Corp.,
442 U.S. 330, 99 S.Ct. 2326, 60 L.Ed.2d 931 (1979), which was issued shortly after
Mid-West.
In
Reiter,
the Court held that consumers who paid artificially high prices for hearing aids could bring a class action to recover the overcharges under § 4. The Court wrote,
[Respondents argue that the cost of defending consumer class actions will have a potentially ruinous effect on small business in particular and will ultimately be paid by consumers in any event. These are not unimportant policy considerations, but they are policy considerations more properly addressed to Congress than to this Court. However accurate respondents’ arguments may prove to be — and they are not without substance — they cannot govern our reading of the plain language of § 4.
442 U.S. at 344-45, 99 S.Ct. at 2333-34.
We conclude that none of TVA’s claims are barred by
Illinois Briek.
Gulf’s motion for partial summary judgment is denied.
APPENDIX
At the competitive price P(c), the market supply curve MC(c) intersects the market demand curve D(m) at output Q(c). If firms agree to restrict output, they must take account of the output of nonconspiring firms (whose supply curve is given by MC(f)) that will enter the market at the higher prices. By subtracting these firms’ output from the market demand at any given price, the cartel can construct the demand curve that it faces (AB) and the marginal revenue curve MR(c) drawn to AB. It may then set its profit-maximizing output where MC(c) intersects MR(c), yielding a price of P(l). At that price, the nonconspirators will expand output to Q(f), where MC(f) equals P(l). The total market output then is Q(f) + Q(l), or Q(m). The area X(l) represents the cost increase from the increased production of the less efficient nonconspirators; the area X(2) represents the welfare loss from the restriction of market output from Q(c) to Q(m).
