Diagrammatic Demonstration of the Cournot Equilibrium

Diagrammatic Demonstration of the Cournot Equilibrium Abstract This note further develops Ikema’s (1990, 1991) diagrammatic demonstration of the Cournot-oligopoly equilibrium on the price-quantity plane. It is shown that Ikema’s method can be used to illustrate the Stackelberg and Bertrand equilibria on the pricequantity plane. Furthermore, we algebraically derive the “monopoly-equilibrium” curve and show that the Cournot-oligopoly equilibrium is stable if the monopoly-equilibrium curves for all producers are upward sloping. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The Japanese Economic Review Springer Journals

Abstract

Abstract This note further develops Ikema’s (1990, 1991) diagrammatic demonstration of the Cournot-oligopoly equilibrium on the price-quantity plane. It is shown that Ikema’s method can be used to illustrate the Stackelberg and Bertrand equilibria on the pricequantity plane. Furthermore, we algebraically derive the “monopoly-equilibrium” curve and show that the Cournot-oligopoly equilibrium is stable if the monopoly-equilibrium curves for all producers are upward sloping.
