Assume we have a constant cost industry. Suppose that each firm has total cost TC(q) = 200 + 20q + 8q^2, and marginal cost MC(q) = 20 + 16q. The market demand curve is QD(P) = 10,000 - 50P. In class, we have shown that in a long-run perfectly competitive equilibrium, each firm manufactures 5 units, and that the equilibrium price is equal to 100. We have also shown that in a long-run equilibrium, 1,000 firms operate. Now, consider a demand shock so that the new market demand curve is given by QD(P) = 15,000 - 62.5P. What is the new long-run equilibrium price and individual quantity? How many firms operate in the new long-run equilibrium?
