The average total cost curve is U-shaped. At the quantity of output where average total cost is at its minimum, is the marginal cost curve above the average total cost curve, below the average total cost curve, or intersecting the average total cost curve?
A firm's learning curve, which shows the relationship between average cost and cumulative output (the sum of its output since the firm started producing), is AC = a + bn", where AC is its average cost; N is its cumulative output; and a, b, and r are constants. What is the firm's AC if r=0? If r= 0, then AC = a + b. (enter formula) If r= 0, what can you say about the firm's ability to learn by...

Suppose a firm's total cost of production (TC) is TC = 20 MC = 40 What do the firm's average total cost curve, average variable cost curve, and marginal cost curve look like? Draw the following curves from 0 to 5 units of output. 1.) Using the line drawing tool.graph the firm's average total cost curve and label it ATC 2.) Using the line drawing tool, graph the firm's...
11. In drawing an isoquant curve, what is measured on the axes? a. the prices of the inputs b. price and output c. the physical quantities of the two inputs d. expenditure on the two inputs e none of the above 12. Learning by doing doctrine suggests that: a. MC shifts upward as current output increases b. an increase in this period's output will cause future periods' long-run average cost curves to be lower c. The long-run average cost curve...
Suppose each firm's long run average cost curve, for positive levels of output, is given by AC = 0.1 + 0.05Q + 5/Q. The marginal cost curve is given by MC = 0.1 + 0.1Q. (a) Find the minimum efficient scale for the above cost function. (b) What is the firm's minimum average cost? (c) Suppose you have many identical firms in a long run competitive equilibrium. Demand is P = 13.1-0.04Q. What is the market quantity? How many firms...
When a firm has a natural monopoly, the firm's a. marginal cost curve must lie above the firm’s average total cost curve. b. marginal cost always exceeds its average total cost. c. average total cost curve is downward sloping. d. total cost curve is horizontal.
19. Assume that marginal revenue equals rising marginal cost at 100 units of output. At this output level, the firm's average fixed cost is $6 and its average total cost is $10. The price of the product is $8. In order to maximize profit, the competitive firm should: a. shut down b. produce 100 units c. produce more than 100 units d. produce less than 100 units e. indeterminate 20. If the entry of new firms into a perfectly competitive...
4) Suppose each firm's long run average cost curve, for positive levels of output, is given by AC 0.10.05Q+5/Q. The marginal cost curve is given by MC 0.+0.1Q. (a) Find the minimum efficient scale for the above cost function (b) What is the firm's minimum average cost? (c) Suppose you have many identical firms in a long run competitive equilibrium. Demand is P 13.1-0.040. What is the market quantity? How many firms are there? (d) Suppose demand increases to P...
Question 3 Long-run average total cost (LAC) O a represents the lowest average cost of producing a given level of output. b. is always equal to or greater than short-run average total cost. c. can be measured in the short-run. If a firm is producing the level of output at which long-run average cost equals long-run marginal cost, then a long-run marginal cost is at its minimum point b. long run average cost is at its minimum point. c long...
riod's output will cause future periods' long-run average cost curves to be lower 12 Learning by doing doctrine suggests that: MC shifts upward as current output increases b. an increase in this period's output long-run average cost curve to increase at a smaller output d the Law of Diminishing Returns to be violated e, none of the above 13. If given quantities of soap and sham be produced separately then: both production processes must be characterized by economies of scale...
