5. equilibrium analysis Repeat Example 10.4 for the case where C(qi; P) = 200qi−18q2 i+q3 i .35 6. duopoly and sequential play Return to the duopoly setting in Example 10.4, but now suppose, instead of simultaneous play, that the first firm can announce and commit to a production plan for itself before the second firm decides on a production plan. Find the first firm’s best quantity choice, and the second firm’s best choice upon hearing the first firm’s announcement.
How does this change in the "rules of the game" help the first firm? What does it do to the second firm?
