Use the following information to answer questions 22-24. Suppose you are given the following information about a particular industry: ABC QD = 6400 -200P Market demand TC(q) = 400 + Firm total cost MC(q) = Firm marginal cost ATC(q) = 400 +-9 Firm average total cost Assume that all firms are identical and that the market is characterized by perfect competition. 22. What is the long-run equilibrium quantity? A. 100 B. 200 C. 400 D. 800 sets. They compete in 23. What is the long-run equilibrium price? A. $1 Firm B. $2 C. $10 Low D. $20 20 Low 82.12 24. How many firms will this industry sustain in the long-run? A. 10 28, 20 B. 15 C. 20 D. 50 Wash equilibria B. The Nash equilibrium 25. Suppose duopolists face the market inverse demand curve P = 100 - q1 - 92, and both firms a constant marginal cost of 10. If firm 1 is a Stackelberg leader and firm 2's best response func 92 = (100 - q1)/2, at the Nash-Stackelberg equilibrium firm 1's output is A. 70 and curte B. 60 then price. C. 40to avenge revenge D. 30 more than price
