b. prevent resale of the product between customer groups.
c. maximize profits at the point where average total cost is minimized.
d. do both a and b, but not c.
9. If economic profits were present in a competitive price-searcher industry,

eliminated.
b. firms would operate in the short run, but they would be forced out of business in the long
run as competition eliminated the economic profit.

d. Groups will pay identical prices that are exactly equal to the firm's marginal cost.
11. Neither price takers nor competitive price searchers will be able to earn long-run economic profit because
