Cournot duopoly model
(1838)
Named after French economist Antoine Augustin Cournot (1801-1877), Cournot duopoly model shows two firms that react to one another's output changes until they eventually reach a position from which neither would wish to depart.
Both firms eventually expand to such a degree that they have equal shares in the market and secure only normal profits.
