This document defines different types of markets and provides examples of each. It begins by defining a market as a place where buyers and sellers can exchange goods and services, whether physical or virtual. It then outlines four main types of markets: perfect competition, where many small businesses sell identical products; monopolistic competition, where many similar substitutes are offered with low barriers to entry; monopoly, where one seller dominates; and oligopoly, where a small number of large firms control most of the sales. Examples are provided for each market type.
