Cournot competition
Cournot competition is an economic model describing a market where n ≥ 2 {\displaystyle n\geq 2} firms simultaneously compete by choosing the quantity of goods to produce and sell in the market. The stage game is one such that there are no fixed costs and constant marginal cost M C = c ≥ 0 {\displaystyle MC=c\geq 0} .
