THE ROBINSON-PATMAN ACT AND QUANTITY DISCOUNTS.
The Robinson-Patman Act is an amendment to the Clayton Anti-Trust Law. The primary purpose of this amendment is to do away with price differentials as between competing customers to the extent that they were not warranted by economic considerations. The law grew out of the fact that certain groups having great buying power, such as leading chains and mail-order houses, seemed to have buying advantages that were not possessed by the multitude of their smaller competitors: advantages which appeared to be out of proportion to the actual economies growing out of trading in the larger quantities of merchandise. The act has two main parts, the civil and the criminal. Violation of this provision of the law subjects the violator to punishment by the Federal Government with fines or imprisonment, or both, inflicted in case of conviction. Cost accountants as such are primarily interested in the first part of the act which involves the granting of quantity discounts and the proper justification thereof. It is obvious that transactions in order to become subject to the provisions of the act must have certain features. There must be a group of transactions in which there is a price discrimination as between different customers. They must be transactions in interstate commerce.
