Answer to Question 1

No. The short-run average cost curves are u-shaped because of gains from division of labor in the beginning and then diminishing returns due to the fixed scale of production in the short run. In the long run, the firm is able to change its scale of production so no diminishing returns occur. Thus, the shape of the long-run average cost curve depends on whether the firm faces increasing, constant, or decreasing returns to scale.

Answer to Question 2

A
