Endogenous number of firms, horizontal concentration and heterogeneity of firms—A note

  • Münter, Markus Thomas

Abstract

We re-examine implications of heterogeneity of firms under a Cournot setting on free entry equilibria concerning the number of firms. Heterogeneity reduces the number of firms in equilibrium—the larger the cost asymmetries, the smaller the free entry equilibrium number of firms in an industry.
