Which of the following actions is NOT prohibited by antitrust laws among competing brokers?

Receiving compensation from both the buyer and the seller is not prohibited by antitrust laws among competing brokers, as long as there is full disclosure and consent from all parties involved. In real estate transactions, it is common for agents to represent both sides (the buyer and the seller) and receive a commission from both, as long as the terms are clearly communicated and agreed upon.

Antitrust laws are primarily concerned with practices that restrict competition and harm consumers, such as price-fixing agreements, market allocation, and collusion among competitors to restrict competition. These practices limit free market operations and can result in higher prices or reduced choices for consumers. In contrast, the practice of an agent receiving compensation from both parties, with proper disclosures, aligns with a transparent business practice that is acceptable under these laws.
