Robinson-Patman Act of 1936

The Law Amendment to the federal Clayton Act of 1914 that outlawed price discrimination

Date 1936

Also known as Anti-Chain-Store Act

The act prohibited price discrimination that damaged competition within a market. The act applies to both buyers and sellers in that it is just as illegal to accept a discriminatory price from a vendor as it is to offer a discriminatory price to a buyer. The act does not apply to export sales.

Named for the bill’s sponsors, Senator Joseph Taylor Robinson and Representative Wright Patman, the act bans sales that discriminate in price between equally situated customers in interstate commerce when the effect of such sales would reduce competition or create a monopoly. The act came about because of practices during the 1930’s wherein large chain stores were given lower prices than independent retailers.

Price refers to net price and therefore includes all compensation paid. This means that the seller cannot disguise the price by giving discounts, commissions, or rebates to special customers. An injured party may sue for treble damages, or the Department of Justice or Federal Trade Commission (FTC) may bring an action under the act. To stop the practice of price discrimination, the act applies to both buyers and sellers; both can be found guilty if there is price discrimination.

Price differentiation between customers is permitted on the basis of quantity purchased if it can be shown that there is a cost savings with the larger order. In other words, the cost savings of large shipments can be passed along as a quantity discount if the savings can be documented. To be discrimination, the sales in question must be contemporaneous in time and the goods must be of like grade and quality. Matching the price of a competitor is a defense, which means that the harm-to-competition requirement is the determining factor in winning or losing a case.

Impact

The act seemingly scared businesses into compliance. Court cases have been surprisingly few. Some writers have claimed that the act has not always been vigorously enforced by the FTC. However, because this is a federal law, the sales must cross state lines; in other words, they must be in interstate commerce. Thus, the overall impact has been positive because the act basically eliminated price discrimination among different competitors.
