Suppose a firm in a competitive industry has the following cost curves:
If the price is $4.50 in the short run, what will happen in the long run?
a.Nothing. The price is consistent with zero economic profits, so there is no incentive
for firms to enter or exit the industry.
b.Individual firms will earn positive economic profits in the short run, which will entice
other firms to enter the industry.
c.Individual firms will earn negative economic profits in the short run, which will cause
some firms to exit the industry.
d.Because the price is below the firm‘s average variable costs, the firms will shut down.

different customers at different prices.
d.increases the consumer surplus associated with a monopolistic market.
