QUESTION 14

Consider a competitive market with 50 identical firms. Suppose the market demand is given by the equation QD = 200 - 10P and the market supply is given by the equation QS = 10P. In addition, suppose the following table shows the marginal cost of production for various levels of output for firms in this market.

How many units should a firm in this market produce to maximize profit?

1 unit

2 units

3 units

4 units

QUESTION 16

In a market with 1,000 identical firms, the short-run market supply is the

marginal cost curve above average variable cost for a typical firm in the market.

quantity supplied by the typical firm in the market at each price.

sum of the prices charged by each of the 1,000 individual firms at each quantity.

QUESTION 17

Mrs. Smith is operating a firm in a competitive market. The market price is $6.50. At her profit-maximizing level of output, her average total cost of production is $7.00, and her average variable cost of production is $6.00. Which of the following statements about Mrs. Smith’s firm is correct?

Mrs. Smith is earning a loss and should shut down in the short run.

Mrs. Smith is earning a loss but should continue to operate in the short run.

Mrs. Smith is earning a profit since the price is above the average variable cost.

the firm can earn economic profits.

BP3DE.

AP3DF.

0AFQ4.

0Q4DP3.

ABEF

Explanation / Answer

ques 20) d. all options reiterate the same fact that in the long run a firm will enter a competitive industry if TR>TC or firm earns economic profits. P>ATC or P>TC/Q or PQ>TC or TR>TC.

ques 12) c. if it can influence the prices, i.e., it is not a price-taker.

ques 16) d. sum of quantities supplied by the 1000 firms at each price.

ques 17) b. At eq MC=P, thus here P<ATC implying an overall loss but P>AVC thus there are operating profits. Hence in the short run it should continue to produce as long as there are operating profits.

Note: for the other ques figures are not visible.
