Agriculture Economics QUESTION #11863
Question 1
A rational producer would never operate in Stage III of production because in that stage:
  • Marginal physical product is negative, $MPP < 0$✔️
  • Average product is at its maximum
  • Marginal cost is minimized
  • Total product is still rising rapidly
Correct Answer Explanation
In Stage III, adding more variable input actually reduces total output, so $MPP < 0$ — no rational firm operates there.
