Refer to Table 13-3. The marginal product of the fourth worker
is
Select one:
a. 10 units.
b. 60 units.
c. 230 units.
d. 240 units.
1. Option B. long-run average total costs fall as output increases.
Explanation: In economies of scale, a firm faces falling average total cost with a rise in output.
2. Option D. 90 dollars
Explanation: Total cost = fixed cost + variable cost = $50 + $40 = $90.
3. Option A. 10 units
Explanation: The marginal product of the 4th worker = total product of 4 workers - total product of 3 workers = 240 - 230 = 10 units.

13. As output (plant size) increases, economies of scale occur when the A) long-run average cost increases. B) long-run average cost decreases. C) short-run average total cost decreases. D) long-run average cost stays constant 14. Economies of scale can occur as a result of which of the following? A) increasing marginal costs as the firm increases its size B) higher fixed cost as the firm increases its size C) management difficulties as the firm increases its size D) greater specialization...
please answer all questions!!! When do constant returns to scale occur when long-run total costs are constant as output increases when long-run average total costs are constant as output increases when the firm's long-run average-cost curve is falling as output increases when the firm's long-run average-cost curv is rising as output increases Scenario 13-5 A stationery firm produces and sells staplers. Last year, it produced 5000 staplers and sold each stapler for $10. In producing the 5000 staplers, it incurred...

Question 1 In the short run, as output increases, the difference between average total cost and average variable cost decreases. the difference between total cost and average variable cost decreases marginal cost eventually decreases. All of the above are correct. Question 2 The marginal cost curve intersects the at its minimum average variable cost curve average total cost curve average fixed cost curve A and B are both correct. Question 3 Refer to the short-run information provided in Figure 8.5...

Economies of scale refers to when: In the long run when average total cost does not depend on the quantity of output, this is called: Commodities: We assume that in the long run in a perfectly competitive market: Multiple Choice an increase in the quantity of output increases average total cost in the long run. None are correct. average total cost does not depend on the quantity of output in the long run. an increase in the quantity of output...
