What is the Cournot model in simple terms?

The Cournot model of oligopoly assumes that rival firms produce a homogenous product, and each attempts to maximize profits by choosing how much to produce. All firms choose output (quantity) simultaneously. The basic Cournot assumption is that each firm chooses its quantity, taking as given the quantity of its rivals.

A numerical example of the Cournot model follows, where it is assumed that there are two identical firms (a duopoly), with output given by Qi (i=1,2). Therefore, total industry output is equal to: Q = Q1 + Q2. Market demand is a function of price and given by Qd = Qd(P), thus the inverse demand function is P = P(Qd).

What is the Bertrand competition?

Bertrand competition is a model of competition in which two or more firms produce a homogenous good and compete in prices. Theoretically, this competition in prices, providing the goods are perfect substitutes, ends with the firms selling their goods at marginal costs and thus making zero profits.

What is the difference between Cournot model and Bertrand model?

The difference is that in the Cournot model firms compete by setting quantities as the strategic variable whereas in the Bertrand model they compete by setting prices. This is a key conceptual distinction, which leads to widely differing predictions.
