What is Cournot model in economics?
Cournot competition is an economic model in which competing firms choose a quantity to produce independently and simultaneously. The model applies when firms produce identical or standardized goods and it is assumed they cannot collude or form a cartel.
What are the characteristics of a Cournot model?
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.
Is Cournot perfect competition?
A sequence (net) of Cournot markets (each with a finite number of firms) which converge smoothly to the perfectly competitive limit in terms of both the inverse demand functions and the distributioon of firm technologies is introduced and it is shown that all markets sufficiently far along the sequence have a Cournot …

What is the main point of the kinked demand model?
This model of oligopoly suggests that prices are rigid and that firms will face different effects for both increasing price or decreasing price. The kink in the demand curve occurs because rival firms will behave differently to price cuts and price increases.
What is the collusion model?
In the simplest form of collusion, overt collusion, firms openly agree on price, output, and other decisions aimed at achieving monopoly profits. Firms that coordinate their activities through overt collusion and by forming collusive coordinating mechanisms make up a cartel. Firms form a cartel to gain monopoly power.
