Monopolistic practices occur when a single company or entity dominates a market, limiting competition and controlling prices. This can happen through various means, such as acquiring competitors, setting unfair prices, or creating barriers that prevent new businesses from entering the market. Such practices can lead to reduced choices for consumers and can stifle innovation. Governments often regulate monopolistic practices to promote fair competition and protect consumers. Laws, such as the Sherman Antitrust Act in the United States, aim to prevent companies from engaging in anti-competitive behavior. By enforcing these regulations, authorities seek to ensure a healthy marketplace where multiple businesses can thrive.
