Frequently asked questions
- Why are monopolies a problem?
- Without competition, a monopoly can charge more, offer less, and innovate slowly, since customers have no alternative.
- Are all monopolies illegal?

- What are antitrust laws?
- Laws that promote competition by restricting monopolies, price-fixing, and mergers that would give one firm too much market control.
