A constant-cost perfectly competitive market is in long-run equilibrium. At present, there are 1,000
firms each producing 400 units of output. The price of the good is $60. Now suppose there is a

compare to what it was before the price of the good rose?

demand will drive up input prices.

each producing 5,000 units of output. The prevailing market price is $20. Assume that each firm
faces increasing marginal cost. Now suppose there is a sudden increase in demand for the

B)
In the short run the typical firm increases its output but its total cost also rises. Hence, the
effect on the firm's profit cannot be determined without more information.
