which all measures of concentration and indexes of aggregate monopoly power derived from the Lerner index, should possess. On this theoretical basis, they have demonstrated that within the confines of varions oligopoly models (non-cooperative Cournot-Nash, price leadership, differentiated oligopoly models), the main measures of concentration, including the entropy measure, can be related to indexes of aggregate degree of monopoly. Using the property of the entropy measure according to which it can be decomposed into additive elements, the authors have also disentangled the respective roles of concentration within a class of firms (or products) and between classes, in the determination of monopoly power.En dépit du recours habituel, en écon...
