Under perfect competition the term industry refers to the collection of Under perfect competition the term industry refers to the collection of firms producing a homogeneous product. But under monopolistic firms producing a homogeneous product. But under monopolistic competition the products of various firms are not identical though they competition the products of various firms are not identical though they are close substitutes. Prof. Chamberline calls the collection of firms are close substitutes. Prof. Chamberline calls the collection of firms producing close substitute products as a group.
