Graphically show the relationship between the total fixed cost, the total variable cost, and the total cost. Draw a total cost curve and total revenue curve so that at some outputs that the firm takes losses, outputs where the firm makes unnecessary profits, and where the firm makes only necessary profits. Then, pick a point where the firm is taking losses and show on the graph, the firm’s total losses. Do the same for a point (an output level) where the firm may be making unnecessary profits.
Douglas Fur is a small manufacturer of fake-fur boots in Chicago. The following table shows the company’s total cost of production at various production quantities.
Fill in the remaining cells of the following table.
On the following graph, plot Douglas Fur’s average total cost (ATC) curve using the green points (triangle symbol). Next, plot its average variable cost (AVC) curve using the purple points (diamond symbol). Finally, plot its marginal cost (MC) curve using the orange points (square symbol). (Hint: For ATC and AVC, plot the points on the integer; for example, the ATC of producing one pair of boots is $200, so you should start your ATC curve by placing a green point at (1, 200). For MC, plot the points between the integers: For example, the MC of increasing production from zero to one pair of boots is $80, so you should start your MC curve by placing an orange square at (0.5, 80).)
Note: Plot your points in the order in which you would like them connected. Line segments…
Douglas Fur is a small manufacturer of fake-fur boots in Dallas. The following table shows the company’s total cost of production at various production quantities.
On the following graph, plot Douglas Fur’s average total cost (ATC) curve using the green points (triangle symbol). Next, plot its average variable cost (AVC) curve using the purple points (diamond symbol). Finally, plot its marginal cost (MC) curve using the orange points (square symbol). (Hint: For ATC and AVC, plot the points on the integer; for example, the ATC of producing one pair of boots is $155, so you should start your ATC curve by placing a green point at (1, 155). For MC, plot the points between the integers: For example, the MC of increasing production from zero to one pair of boots is $95, so you should start your MC curve by placing an orange square at (0.5, 95).)

The long-run is a period of time long enough so that all inputs, including facility and equipment, are variable, while in the short run at least one input is fixed. Think about how much time it would take to change the scale of operation for a restaurant, for an automobile plant, for a website designing company... Does it seem that the amount of time that separates the long run from the short run is industry-specific, rather than a set period of time? Share three specific examples.

- Each graph illustrates three short-run cost curves for firms, where ATC is average total cost (also referred to as average cost), MC is marginal cost, and AVC is average variable cost. Please classify each of the graphs as valid or invalid based on what you know about the relationships between these curves.arrow_forwardA watch manufacturer finds that at 1,000 units of output, its marginal costs are below average total costs. If it produces an additional watch, will its average total costs rise, fall, or stay the same?arrow_forwardA student has just written on an exam that, in the long run, fixed cost will make the average total cost curve slope downward. Why will the professor mark it incorrect? In the long run, fixed cost increases as firms build new plants and purchase new capital. This means that the average total cost curve will eventually slope upward. In the long run, firms have no fixed cost—all costs would be variable. The shape of the long-run average total cost curve is determined by economies of scale. In the long run, fixed cost decreases as costs are spread out over a greater quantity of output. Declining fixed cost accounts for the downward-sloping average total cost curve. In the long run, there are no fixed costs, meaning the average total cost curve shifts down.arrow_forward
