This document defines different types of markets and provides examples of each. A market is where buyers and sellers interact and establish competition between buying and selling, regardless of physical place. The main types of markets discussed are perfect competition, monopoly, oligopoly, and monopolistic competition. Perfect competition has many small sellers and buyers trading standardized products. A monopoly has only one seller of a unique product without close substitutes. Oligopoly is dominated by a small number of large firms. Monopolistic competition involves differentiated products with easy market entry and exit. Examples are given for each type of market.
