1. When there are decreasing returns to scale, the short-run average total cost of the firm is:

1. If there are external diseconomies in an industry, after a permanent increase in demand, the long-run market price:

 a. is higher than initially. b. is lower than initially. c. is the same as initially. d. may be higher or lower depending on whether the firm is earning economic profits.

QUESTION 18

1. If the market price of a perfectly competitive firm's product is below its average variable cost, then the firm's:

 a. marginal revenue is zero. b. total revenue is as large as possible. c. total revenue if it stayed open would be less than its total variable costs. d. total revenue if it stayed open is less than its total costs but greater than its total fixed costs. e. none of the above.

1 - Option B

Decreasing with respect to output

This is because the gap between them i.e AFC declines with respect to output

2 - Option D

always occurs where the minimum point on the short run average cost is to the right of its point of tangency with the long run average cost curve.

3 - Option E

Never equal to long run ATC

This is because , as result of diseconomies of scale , the long run average cost rises and is not equal to SRAC

4 - Option D

Setting its price so that it is equal to marginal cost

MR = MC is the profit maximising condition

5 - Option B

Marginal cost curve above intersection with AVC.
