This differs from the Bertrand competition model ...
There is a big incentive to cooperate in the Bertrand model; colluding to charge the monopoly price, , and sharing the market equally, , where is the number of firms in the market. [13] However, not colluding and charging marginal cost is the non-cooperative outcome and the only Nash equilibrium of this model. [ 7 ]
