Suppose the demand function is Q = 400 - 10p. Firm A, the leader, acts before Firm B, the follower. Both firms have a constant marginal cost of 20. Draw a diagram with Firm A’s output on the horizontal axis. Show the best-response function of Firm B. On the diagram, identify the Nash-Cournot solution, the Stackelberg solution, and the cartel solution.
