a. two b. three
c. five d. four

Which of the following phenomena is not reflected in the long-run average cost curve?

a. Maximum efficient scale b. Constant returns to scale
c. Economies of scale d. Diseconomies of scale

How is minimum efficient scale best defined?

a. The point where economies of scale end and constant returns to scale begin b. The point where economies of scale start

Homework Answers

Answer #1

In order to construct the LRAC curve, the short run average total cost curves are used.

1). The correct option is (a).

Short-run average total cost curves are used.

2). The correct option is (b).

Three

There are three different areas moving along the LRAC curve.

3). The correct option is (a).

Maximum efficient scale.

The phenomenas which are associated with LRAC curve are Constant Returns to scale, economies of scale and diseconomies of scale.

Maximum efficient scale is not associated with LRAC curve.

4). The correct option is (a).

The point where economies of scale end
and constant returns to scale begin.

minimum efficient scale (MES) or efficient scale of production is the lowest point where the plant (or firm) can produce such that its long run average costs are minimized.

7. Long-run average cost curves The following graph shows the short-run average total cost curves and the long-run average cost curve for a publishing firm. The five marked quantities indicate points of tangency between each short-run average total cost curve (SRATCSRATC) and the long-run average cost curve (LRACLRAC); for example, Q1Q1 marks the point of tangency between SRATC1SRATC1 and LRACLRAC. The orange point on SRATC1SRATC1 indicates the firm's current output level in the short run (Q2Q2). COST PER UNITQUANTITY OF...
