A corporate monopoly occurs when a single company dominates a particular market, controlling a large share of the industry. This dominance can limit competition, leading to higher prices and fewer choices for consumers. Monopolies can arise through various means, such as mergers, acquisitions, or aggressive business practices. Governments often regulate monopolies to promote fair competition and protect consumers. Antitrust laws, like the Sherman Act in the United States, aim to prevent companies from engaging in anti-competitive behavior. By ensuring a competitive market, these regulations help maintain innovation and keep prices in check for consumers.
