Economics Letters, 2018, vol. 165, issue C, 62-64

Abstract: In the framework of Cournot oligopoly with heterogeneous firms, under conditions weaker than the commonly accepted ones, this paper provides (i) a proof that the equilibrium price (total output) does not increase (decrease) as the number of firms in the industry increases, and (ii) a necessary and sufficient condition for entry to strictly lower the equilibrium price.
