In the study of market structures, what characterizes a monopolistic competition model as formulated by Edward Chamberlin?

A. Homogeneous products sold by a large number of price-taking firms with free entry and exit
B. A single dominant producer controlling the entire market supply with absolute price-setting power
C. Differentiated products sold by many firms possessing some degree of monopoly power over their brand✓ Correct Answer
D. A small number of interdependent firms engaging in strategic pricing and non-price competition

💡 Solution & Explanation

Monopolistic competition features a large number of independent firms producing differentiated products that are close substitutes, granting each firm slight price-setting power. Unlike perfect competition where goods are homogeneous, product differentiation through branding and marketing creates a downward-sloping demand curve for individual firms. Free entry and exit ensure that economic profits tend toward zero in the long run equilibrium. Oligopoly, by contrast, is characterized by strategic interdependence among a small number of large firms.
