Nash equilibrium bertrand model
WitrynaThe “Bertrand trap” With only two firms, price is driven down to the perfectly competitive price (marginal cost). This is the only Nash equilibrium of the Bertrand game. Economic profits are zero (so accounting profits could be negative if there are sunk costs). Adding just one firm takes us from monopoly to perfect competition!
