Chamberlin's book is often compared to Robinson's in which she coined the term "monopsony" to describe the buyer converse of a seller monopoly.

Monopsony is commonly applied to buyers of labor, where the employer has wage setting power that allows it to exercise Pigouvian exploitation[1] and pay workers less than their marginal productivity.

This field encompasses many topics, including profit maximization, market power, product quality, and antitrust law, which is imperative when studying firm behavior and business practices [5](Church and Ware, p. 12).

Several facets of industrial organization are embedded in Chamberlin's economic theories, including product differentiation and the use of patents to maximize profits and strengthen one's monopolistic position in the market.

Chamberlin is also considered one of the first theorists who applied the marginal revenue idea, which is implicit on Cournot's monopoly theory in the late 1920s and early 1930s.
