Assume you are one of two manufactures of tennis balls. Both you and your competitor have zero marginal costs. Total demand for tennis balls is

P = 60 - Q
Where Q = the sum of the outputs of you and your competitor.

a) Assume you are in this situation only once. You and your competitor have to announce your individual outputs at the same time. You expect your competitor to choose the Nash equilibrium strategy. How much will you choose to produce and what is your expected profit?

b) Now Assume that you have to announce your output before your competitor does. How much will you choose to produce? What is your expected profit? Is it an advantage or a disadvantage to move first? Explain.
