Who gave the concept of Monopolistic competition ?

Question

Accepted Answer

The correct option is 2:
The concept of Monopolistic Competition was independently developed and formalized by Edward Hastings Chamberlin in his seminal 1933 book, *The Theory of Monopolistic Competition*. This market structure bridges the gap between the two extremes of perfect competition and pure monopoly. In monopolistic competition, many firms compete, but each firm sells a slightly differentiated product (through branding, quality, location, etc.). This product differentiation grants each firm a small degree of monopoly power over its unique product, allowing them to influence the price, yet the presence of many close substitutes means that entry drives long-run economic profits to zero. Chamberlin's work was crucial for introducing product differentiation and selling costs as key elements in economic analysis.

The incorrect option is 1:
Mrs. Joan Robinson is another highly influential economist who published her work, *The Economics of Imperfect Competition*, also in 1933, around the same time as Chamberlin. While Robinson's work also dealt with intermediate market structures, her focus was primarily on 'imperfect competition' and the analysis of monopoly and duopoly power, rather than the specific model of monopolistic competition characterized by product differentiation as articulated by Chamberlin.

The incorrect option is 3:
J. R. Hicks, a Nobel laureate, is best known for his contributions to general equilibrium theory, consumer theory, and welfare economics, including the development of the IS-LM model. Although he made significant contributions to economic theory, he is not credited with originating the theory of monopolistic competition.

The incorrect option is 4:
J. M. Keynes, or John Maynard Keynes, is one of the most famous economists of the 20th century and is recognized as the father of modern macroeconomics. His major contributions, outlined in *The General Theory of Employment, Interest, and Money* (1936), focused on issues of aggregate demand, unemployment, and government intervention, making him unrelated to the foundational concept of monopolistic competition market structure.
