What is the Bertrand model in economics?

In a Bertrand model of oligopoly, firms independently choose prices (not quantities) in order to maximize profits. This is accomplished by assuming that rivals’ prices are taken as given. The resulting equilibrium is a Nash equilibrium in prices, referred to as a Bertrand (Nash) equilibrium.

Bertrand developed his duopoly model in 1883. His model differs from Cournot’s in that he assumes that each firm expects that the rival will keep its price constant, irrespective of its own decision about pricing.

What is the Cournot model in economics?

The Cournot model was based on the economist Antoine Augustin Cournot’s investigation of the duopoly in French spring water. In his model he assumes firms produce a homogenous product, they do not co-operate, firms act rationally and they have market power.

Who developed the model of duopoly?

Bertrand, a French Mathematician developed his own model of duopoly in 1883. Bertrand’s model differs from Cournot’s model in respect of its behavioural assumption.

## What are the limitations of Cournot’s duopolistic model?

The original version is quite limited in that it makes the assumption that the duopolists have identical products and identical costs. Actually Cournot illustrated his model with the example of two firms each owning a spring of mineral water, which is produced at zero costs.
