Antitrust in the Internet Era: The Legacy of United States v. A&P

  • Published:
Review of Industrial Organization Aims and scope Submit manuscript


Critics from both the right and the left claim that modern antitrust doctrine, rooted in consumer welfare, is inadequate to handle the challenges of the twenty-first century economy. They express nostalgia for 1960s antitrust, when the field had no clear objectives and cases were decided on impressionistic notions of “fairness” and good corporate citizenship. This article exposes the intellectual void at the heart of this new populist movement and begins by following Justice Holmes’ tenet that “a page of history is worth a volume of logic.” More than 80 years ago, the A&P grocery chain was a vertically integrated retailer that made use of unprecedented scale and innovation to offer consumers a wider range of products than the competition and at lower prices. Yet A&P’s very success, which came at the expense of smaller and less efficient competitors, triggered a backlash: first from Congress, in the form of the Robinson–Patman Act, and then from the Justice Department, in the form of successful prosecution under the Sherman Act. These attacks on A&P bear an eerie resemblance to attacks today on leading online innovators. Increasingly integrated and efficient retailers—first A&P; then “big box” brick-and-mortar stores; and now online retailers—have challenged traditional retail models by offering consumers lower prices and greater convenience. For decades, critics across the political spectrum have reacted to such disruption by urging Congress, the courts, and the enforcement agencies to stop these American success stories by revising antitrust doctrine to protect small businesses rather than the interests of consumers. Using antitrust law to punish pro-competitive behavior makes no more sense today than it did when the government attacked A&P for offering consumers too good a deal on groceries. In addition, antitrust doctrine does not need an overhaul. It is shaped by many economic perspectives, follows no one “School,” and is flexible enough to address any monopoly abuses in today’s economy. It is also well-calibrated to serve its central function: promoting consumer welfare. It does so not only by prohibiting conduct that harms consumers in the long run, but also by avoiding interference with conduct that might appear problematic to non-economists but that demonstrably benefits consumers over time. Antitrust remains a work in progress, but it is far superior to any alternative that the critics propose.

In Brown Shoe, the Supreme Court rejected a merger between a shoe manufacturer and a shoe distributor because (inter alia) the merger “foreclosed” competitors from a tiny percentage (2–5%) of the relevant markets, which were unconcentrated. The Court acknowledged that such consolidation can be “beneficial to consumers” but ultimately deemed it more important “to promote competition through the protection of viable, small, locally owned business[es]” even though “occasional higher costs and prices might result from the maintenance of fragmented industries and markets.” 370 U.S. at 344. In Utah Pie, the Court upheld a treble-damages award against national frozen pie manufacturers for selectively reducing prices in the Salt Lake City market to undersell a local company that occupied two-thirds of the market there. 386 U.S. at 702.

A&P had made the same point at trial, calling Harvard Business School professor Malcolm McNair to explain: “The business of food distribution is just about the last business I can think of in which it would be feasible for anybody to develop a monopoly.” Levinson, supra note 15, at 232.

  49. Id. at 231.

  50. Id. In a variation on this theme, the court of appeals affirmed the convictions in part on the ground that “[w]hen the gross profit rate is reduced in Area X [to meet competition], it is an almost irresistible conclusion that A&P had the power to compensate for any possible decline in net profits by raising the gross profit rate and retail prices in Area Y, where it was in a competitive position to do so.” 173 F.2d at 87. This makes no sense: A&P presumably strove to maximize long-term profits when setting its prices everywhere, and it would have been irrational to deviate from a profit-maximizing strategy in Area Y simply because the company decided to lower prices to meet competition in Area X.

  102. Id. Khan claims that the discounts Amazon obtained from delivery companies have harmed third-party merchants because the “[d]elivery companies sought to make up for the discounts … by raising the prices they charged to independent sellers.” Id. at 775. This claim parallels the A&P prosecution’s charge that “[t]he consumers who [bought] food in stores competing with A&P pa[id] part of the low cost of A&P’s operation” on the theory that the food suppliers who gave A&P discounts made up for them by raising prices to other grocery stores. Levinson, supra note 15, at 231. In both cases, the claims contradict the basic economics of individualized bargaining: Suppliers can normally be expected to charge each buyer the highest price it can negotiate from that buyer, irrespective of whatever concessions they make to other buyers.

These studies and the concentration debate are summarized in Industrial Concentration: The New Learning (Harvey Goldschmid et al. eds., 1974); see also Wesley Liebeler, Bureau of Competition: Antitrust Enforcement Activities, in The Federal Trade Commission Since 1970: Economic Regulation And Bureaucratic Behavior 65 (Kenneth Clarkson and Timothy Muris eds. 1981).

  141. 384 U.S. 270 (1966). Just as the unlikely advocate for the government in A&P v. FTC (the 1979 Robinson–Patman case) was Frank Easterbrook, see note 42, supra, the unlikely advocate for the government in Von’s Grocery was Richard Posner. In a 1992 interview, Posner remarked that he was “perfectly convinced of the soundness of the government’s position” when he argued the case in 1966 but subsequently concluded that the merger “was completely harmless.” Interview with Judge Richard Posner, Seven Circuit Court of Appeal, 6 Antitrust 4, 5 (Spring 1992).

  142. 384 U.S. at 272, 277. As Justice Stewart remarked in dissent, this outcome was perplexing because “[t]here is simply no evidence in the record … that the increment in market share obtained by the combined stores can be equated with an increase in the market power of the combined firm.” Id. at 297.

  144. See id.; see also Jeffrey Perloff et al., Estimating Market Power and Strategies 33 (2007) (“Many researchers, after finding a link between high profits (or excessive rates of return, or large price–cost margins …) and high concentration ratios, infer improperly that high concentration rates are bad because they ‘cause’ high profits. However, profit and concentration influence each other. An alternative interpretation of a link between profits and concentration is that the largest firms are the most efficient and innovative. Only when a firm is efficient or innovative is it profitable to expand in a market and make the market concentrated. In this interpretation, a successful firm attracts consumers, either through lower prices or better products. A firm’s success, as measured by both its profits and its market share, is an indicator of consumer satisfaction, not of poor industry performance.”) (citation omitted).

  145. See generally Transcript of FTC Workshop, Horizontal Merger Guidelines Review Project, No. P092900 (Jan. 26, 2010), A “4-to-3” merger is one that combines two firms in a market occupied by four major participants, leaving three post-merger firms. Unlike the guidelines that followed, the 1968 version lacked uniform benchmarks. In some cases, the 1968 guidelines condemned mergers in markets with more than eight equal-sized competitors.
