Anti-competitive behavior refers to actions taken by companies to limit competition in a market. This can include practices like price-fixing, where businesses agree to set prices at a certain level, or creating barriers that make it difficult for new companies to enter the market. Such behaviors can harm consumers by leading to higher prices and fewer choices. Regulatory bodies, such as the Federal Trade Commission in the United States, monitor and enforce laws against anti-competitive practices. These laws aim to promote fair competition, ensuring that markets operate efficiently and that consumers benefit from a variety of products and services.
