Water's Edge is a small company in Minnesota that makes high-quality,
hand-made sweaters. To produce each sweater, the company must use exactly 1 unit
of capital, 20 hours of labor, and 50 yards of wool. If labor costs $5/hour, wool is
$1/yard, and Pk=$50.
A. Does this production technology exhibit constant, increasing, or decreasing returns to
scale?
B. Here is another production function q = L1/3K2/3 . Does this production technology
exhibit constant, increasing, or decreasing returns to scale? (Show how you get an
answer in detail for full credit)

Solutions

Expert Solution

A.

There are three inputs of production – Capital (K), Labor (L), and Wool (W). Since there is the word “and”, all these are added to get the production function (Q).

Q = K^1 + 20L^1 + 50W^1

The power of each input is 1; these powers should be multiplied to get returns to scale.

Answer: Since (1 × 1 × 1 =) 1, this is constant returns to scale.

B.

Given, Q = L ^(1/3) K ^(2/3)

Here the powers should be added, since the inputs have multiplication in between.

Addition of powers = (1/3) + (2/3)

                                    = (1 + 2) / 3

                                    = 3/3

                                    = 1

Answer: Since the addition is equal to 1, the production function has constant returns to scale.
