2. Edward Chamberlin • For most of his career Edward Chamberlin taught economics at Harvard (1937-1967). He made significant contributions to microeconomics, particularly on competition theory and consumer choice, and their connection to prices. Edward Chamberlin coined the term "product differentiation" to describe how a supplier may be able to charge a greater amount for a product than perfect competition would allow. • His most significant contribution was the theory of monopolistic competition. Chamberlin published his book The Theory of Monopolistic Competition in 1933, the same year that Joan Robinson published her book on the same topic: The Economics of Imperfect Competition, so these two economists can be regarded as the parents of the modern study of imperfect competition. • Chamberlin's theory of monopolisitic competition is used by sociologist Harrison White in his "markets from networks" model of market structure and competition Prof. Bertolami Salvatore
