Notes
  • Often the intensity of competition has been measured through proxies like the degree of product substitutability or as the inverse;of the degree of concentration in an industry. Both visions are based on the implicit assumption that few competitors imply a less though competition, but puzzles arise as several counter-examples exist. Other puzzling issues arise from the lack of a unified approach to oligopolistic equilibria (e.g. Cournot vs Bertrand competition). In this paper the unified approach of competitive toughness proposed by D'Aspremont et al.(2007), offering a generalization of the traditional oligopoly theory encompassing all the possible oligopolistic regimes between the Cournot and the competitive outcome, is discussed, also with respect to its implication for economic growth and macro studies.
