What is Duopoly?

Definition and meaning of duopoly: A duopoly is an oligopoly in which two firms dominate the entire market. It is a situation in which two large political parties, or two powerful individual candidates, have near-total control over the political system, leaving little room for independent candidates or dissenting voices. This type of two-party system is unrepresentative of the diversity of political opinion in a society and can lead to policies that don't reflect the needs of the people.
