Question

5. Costs in the short run versus in the long run

Ike’s Bikes is a major manufacturer of bicycles. Currently, the company produces bikes using only one factory. However, it is considering expanding production to two or even three factories. The following table shows the company’s short-run average total cost (SRATC) each month for various levels of production if it uses one, two, or three factories. (Note: Q equals the total quantity of bikes produced by all factories.)

Average Total Cost (Dollars per bike) Q = 300 Q = 400 Number of factories Q = 100 Q = 200 Q = 500 Q = 600 360 200 240 400 720 540 300 160 160 240 160 300 540 720 400 160 200 360

Suppose Ike’s Bikes is currently producing 100 bikes per month in its only factory. Its short-run average total cost is

per bike.

Suppose Ike’s Bikes is expecting to produce 100 bikes per month for several years. In this case, in the long run, it would choose to produce bikes using   .

On the following graph, plot the three SRATC curves for Ike’s Bikes from the previous table. Specifically, use the green points (triangle symbol) to plot its SRATC curve if it operates one factory (SRATC1SRATC1); use the purple points (diamond symbol) to plot its SRATC curve if it operates two factories (SRATC2SRATC2); and use the orange points (square symbol) to plot its SRATC curve if it operates three factories (SRATC3SRATC3). Finally, plot the long-run average total cost (LRATC) curve for Ike’s Bikes using the blue points (circle symbol).

Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.
