Refer to the diagram for a non collusive oligopolist. We assume that the firm is initially in
equilibrium at point E, where the equilibrium price and quantity are P and Q. If the firm's
rivals will ignore any price increase but match any price reduction, the firm's marginal revenue
curve will be (moving from left to right)
