In 2 or 3 sentences, describe how antitrust laws encourage competition. (this is actually for enconomics class)

Antitrust laws prevent monopolies. A monopoly is a company or business that dominates a particular market to such an extent that there is no viable competition to that company. Since a monopoly does not have any other serious competition in a market, the monopoly is at greater liberty to charge higher prices and offer lower-quality prices. Antitrust laws break up or limit the size of monopolies, allowing other companies to enter a market.
