Price-fixing is an agreement or arrangement between competitors or businesses within the same industry to set, fix, maintain, or stabilize prices of goods or services, rather than allowing market forces to determine them. This is commonly seen as an illegal practice as it restricts competition and can significantly disadvantage consumers by inflating prices artificially. It often violates antitrust and competition laws.
