Concept Of Production And Production Function

Zero

Step 1: Understand the relationship between MP and TP. MP measures the addition to TP when one more unit of variable factor is added. Step 2: When TP is rising, MP is positive. When TP is falling, MP is negative. At the exact peak (maximum) of TP, there is no increase or decrease — the change in TP is zero. Step 3: Therefore, when TP is at its maximum, MP = 0. This is a fundamental relationship in the Law of Variable Proportions. Step 4: Option A is wrong — MP equals AP at the maximum point of AP, not when TP is maximum. Step 5: Option C is wrong — MP reaches its maximum earlier (at the point

The point where TP changes from increasing at an increasing rate to increasing at a diminishing rate.

Step 1: The Point of Inflexion is a specific point on the TP curve where the slope of the curve changes. Step 2: Before this point, TP increases at an increasing rate (Phase I — Increasing Returns). At this point, MP reaches its maximum. Step 3: After this point, TP still increases but now at a diminishing rate (Phase II — Diminishing Returns) because MP starts to fall. Step 4: Option A is wrong — TP becomes zero only when no variable factor is used, not at the inflexion point. Step 5: Option B is wrong — TP is maximum when MP = 0, which is a different (later) point on the curve. Option D is w

Phase II — Diminishing Returns

Step 1: Understand the three phases — Phase I (Increasing Returns), Phase II (Diminishing Returns), Phase III (Negative Returns). Step 2: In Phase I, MP is rising, which means the fixed factor is still being under-utilised. A rational producer would continue adding more variable factors because each addition still increases efficiency. So, a producer would NOT stop in Phase I. Step 3: In Phase III, MP becomes negative, meaning adding more variable factors actually reduces total output. No rational producer would ever operate here as it leads to a loss. Step 4: In Phase II, MP is declining but

MP = AP

Step 1: Understand the mathematical relationship between AP and MP. Step 2: When the marginal value is greater than the average (MP > AP), the average rises. Think of a cricket analogy — if a batsman scores more than his current average, his average goes up. Step 3: When the marginal value is less than the average (MP < AP), the average falls. Similarly, if the batsman scores less than his average, his average falls. Step 4: At the exact maximum (peak) of the AP curve, AP is neither rising nor falling. This happens precisely when MP = AP — the marginal value exactly equals the average. Step 5:
