If the firm can increase its output to 120 units by employing 2 additional units of labor at the same cost as its current capital, which category best describes the firm's decision-making process related to cost minimization?

Choose the Best Answer

A

Increasing labor is justified if the marginal product of labor exceeds that of capital.

B

The firm should always maintain the current levels of labor and capital regardless of output changes.

C

The firm should only invest in capital because it is less variable than labor.

D

Decreasing labor and increasing capital is always the optimal choice.

Understanding the Answer

Let's break down why this is correct

Answer

The firm's decision-making process related to cost minimization is best described as optimizing its resource allocation. By adding 2 more units of labor, the firm increases its output from 100 to 120 units without changing the cost of capital, which means it is using its resources more efficiently. This decision shows that the firm is looking for the best way to maximize production while keeping costs at the same level. For example, if hiring additional labor allows the firm to produce more goods without needing to invest in more expensive machinery, it is effectively minimizing costs while increasing output. This approach helps the firm remain competitive and profitable in the market.

Detailed Explanation

Increasing labor is a good choice if it helps produce more output. Other options are incorrect because Thinking the firm should keep everything the same ignores new opportunities; Believing that capital is always better than labor is a mistake.
