Question 1. 1. A certain competitive firm sells its output for $20 per unit. The 50th unit of output that the firm produces has a marginal cost of $22. Production of the 50th unit of output does not necessarily (Points : 5)      increase the firm's total revenue by $20.

Question 17. 17. Mrs. Smith operates a business in a competitive market. The current market price is $8.50.

      reduce its output but continue operating.

      continue to produce at the current levels.

      increase its output.

Question 21. 21. Which of the following statements regarding a competitive firm is correct? (Points : 5)      Because demand is downward sloping, if a firm increases its level of output, the firm will have to charge a lower price to sell the additional output.

      If a firm raises its price, the firm may be able to increase its total revenue even though it will sell fewer units.

      By lowering its price below the market price, the firm will benefit from selling more units at the lower price than it could have sold by charging the market price.

      For all firms, average revenue equals the price of the good.

Question 22. 22. Scenario 14-1

Assume a certain firm in a competitive market is producing Q = 1,000 units of output. At Q = 1,000, the firm's marginal cost equals $15 and its average total cost equals $11. The firm sells its output for $12 per unit.

The annual loan payment is $25,000 and the boat has a market (salvage) value that exceeds its outstanding loan balance. Prior to the 2010 shrimp harvesting season, Shrimp Galore's accountant predicted that at expected market prices for shrimp, Shrimp Galore would have a net loss of $75,000 dollars after paying all 2010 expenses (including the annual loan payment). In this case, Shrimp Galore should (Points : 5)      produce nothing and experience a loss of $25,000.

      produce nothing and experience a loss of $75,000.

      continue to operate because expected profits will rise in the future.
