Production Function

Correct Answer: Option B — Second Stage

Explanation:

In short-run production, there are three stages of production that describe how output changes with the combination of variable and fixed factors:

1. First Stage:

   • Productivity rises, but the Marginal Product (MP) of each additional unit of the variable input starts to decline

   • The output of each additional worker is increasing

   • Not the most profitable stage because MP > AP

2. Second Stage:

   • MP continues to decline but MP > 0

   • Average Product (AP) reaches its maximum and then starts to decline

   • This is the practical and profitable stage of production

   • Output is stable and efficient in this stage

3. Third Stage:

   • MP < 0, meaning each additional worker decreases total output

   • Producing in this stage is loss-making

Analysis of Options:

• A. First Stage - Not profitable

• B. Second Stage - Correct, this is the stage a rational producer prefers

• C. Third Stage - Loss-making

• D. None of these - Incorrect

Conclusion:

In short-run production, a rational producer always prefers to produce in the second stage.
