In game theory, there are many ways to model an oligopoly market.

- Cournot's model of
*quantity competition*(1803) leads to a result between perfectly competitive pricing and monopoly pricing, because each firm is a "residual monopolist". - Bertrand's model of
*price competition*(1887) leads to the result of perfectly competitive pricing because of extreme price elasticity. - "Kinked demand curve" model supports
*any*outcome, but isn't very "rational". - Price
*and*quantity games.

My paper is about choosing a good model.
