370 U.S. 294 (1962)
The case of Brown Shoe Co. v.
Does the merger between Brown Shoe Co. and G.R. Kinney violate Section 7 of the Clayton Act by substantially lessening competition in the footwear industry?
Under Section 7 of the Clayton Act, a merger is prohibited if it tends to create a monopoly or substantially lessen competition in any line of commerce in any section of the country.
The Supreme Court affirmed the lower court's decision, ruling that the merger between Brown Shoe Co. and G.R. Kinney would likely lead to a substantial lessening of competition in the shoe industry, violating Section 7 of the Clayton Act.
Brown Shoe Co. v. United States is significant because it articulates the 'incipiency' standard under the Clayton Act, stressing intervention before harmful market concentrations occur. It underscores the importance of analyzing both horizontal and vertical integrations in merger cases and highlights key factors such as product and geographic market definitions, market share, trends toward concentration, and potential competitive harms. This case exemplifies the judiciary's role in interpreting antitrust laws to prevent economic monopolization and preserve competitive markets.
