Question

In the long run, assuming that the owner of a firm in a competitive industry has positive opportunity costs, she a. should exit the industry unless her economic profits are positive. b. will earn zero accounting profits but positive economic profits. c. will earn zero economic profits but positive accounting profits. d. should ignore opportunity costs because they are a type of sunk cost that disappears in the long run.

Answer 1

Answer:

c. will earn zero economic profits but positive accounting profits

Explanation:

A competitive industry is characterised by many buyers and sellers of homogenous goods and services.

There are no barriers to entry and exit of firms. If firms in a competitive industry earn economic profit in the short run, firms enter into the industry in the long run and economic profit falls to zero.

A competitive firm earns accounting profit but doesn't earn economic profit.

Accounting profit = Revenue - Cost

Economic profit = Accounting profit - Opportunity cost
