Consider two firms engaging in sequential Stackelberg competition.

Consider two firms engaging in sequential Stackelberg competition.

Suppose firm 1 decides its quantity x1 first and firms 2 follows after observing x1. The demand function of the market is x(p) = 100 - 0.1p and the cost function for both firms are c(x) = FC + 5x2

a. Suppose first that FC = 0. Derive firm 2's best response function to observing firm 1's output level x1.

b. What output level will firm 1 choose?

c. What output level does that imply firm 2 will choose?

d. What is the equilibrium Stackelberg price?

e. Now suppose FC is not zero. What is the lowest FC at which firm 1 does not have to engage in strategic entry deterrence in order to keep firm 2 out of the market?
