Which practice is prohibited under antitrust laws related to property financing?

Price fixing is a practice that is strictly prohibited under antitrust laws because it involves an agreement between parties to set prices at a certain level, rather than allowing them to be determined by free market competition. This collusion can harm consumers by inflating prices, restricting supply, and reducing choices in the market.

Antitrust laws are designed to promote fair competition and prevent monopolistic behaviors, ensuring that consumers benefit from competitive pricing and innovation. When parties engage in price fixing, they undermine these principles by coordinating to manipulate prices, which is why this practice is illegal.

Other options, such as offering discounts to loyal clients, encouraging competitive pricing, and providing referral bonuses, do not typically violate antitrust laws. Offering discounts for loyalty can incentivize repeat business without controlling overall market prices. Encouraging competitive pricing fosters a healthy marketplace where consumers have choices, and referral bonuses can serve to promote business without influencing pricing strategies across competitors.
