Edward Hastings Chamberlin (May 18, 1899 – July 16, 1967) was an American economist. He was born in La Conner, Washington, and died in Cambridge, Massachusetts.
Chamberlin studied first at the University of Iowa (where he was influenced by Frank H. Knight), then pursued graduate studies at the University of Michigan, eventually receiving his Ph.D. from Harvard University in 1927.
In economics, strategic management and marketing, product differentiation (or simply differentiation) is the process of distinguishing a product or service from others to make it more attractive to a particular target market. This involves differentiating it from competitors' products as well as from a firm's other products. The concept was proposed by Edward Chamberlin in his 1933 book, The Theory of Monopolistic Competition.
