Consider a perfectly competitive market with 1000 firms. The cost function of each firm is C(q) = 0.025q^2 + 200. The total demand in the market is given by QD = 60,000 - 10,000P. The supply curve for each firm is given by 20q.
The competitive price in this market is
HINT: you need to first find the total market supply: Each firm is producing
89.4
units.
The competitive market is in long-run equilibrium: 4.5.
