Which term describes a pricing strategy that might be illegal under antitrust laws?

Price fixing is a term that describes a pricing strategy where competing businesses agree on set prices for their products or services, rather than allowing competition to dictate prices. This behavior is considered illegal under antitrust laws because it undermines free market competition and can lead to higher prices for consumers. By colluding to set prices, companies remove the incentive for innovation and efficiency that competition naturally promotes.

In contrast, the other pricing strategies listed, such as uniform delivered pricing and zone pricing, involve different methods of determining prices based on delivery conditions or geographical factors and do not involve collusion among competitors. Bait and switch refers to a deceptive marketing practice where a business advertises a product at a low price to lure customers in, only to push a more expensive or different product when they arrive. While bait and switch can be considered deceptive, it does not directly relate to collusion on pricing among competitors like price fixing does.
