Monopoly

a market structure in which one firm makes up the entire market. the firm faces no competitive pressure from other firms.

Difference between Monopoly and perfect competitor

A competitive firm does not take into account the effect of its output decision on the price it receives. a competitive firm's marginal revenue is the given market price. a monopolistic firm takes into account that its output decision can affect price. its marginal revenue is not its price.
