Question 3

"Assuming the long-run average cost curve is U-shaped, a firm will always seek to operate at the lowest point on the long-run average cost curve."

Accepted Answer

The optimal point in the long run depends on the demand for the firm's product.If demand is small, the firm will prefer a relatively small plant and will operate to the left of minimum LRA
c.A firm anticipating a large demand may find it optimal to produce beyond minimum LRA
c.Later, there will be a tendency to operate at minimum LRAC when a firm faces competition, but there is no such discipline on the firm in this chapter.

Question 8

"A producer wanting to employ optimal quantity of inputs should choose the point where diminishing returns sets in."

Accepted Answer

The correct rule is marginal revenue product = input price.It pays to go beyond diminishing returns so long as MRP is at least as great as input P, which normally requires going past the point of diminishing returns.
