Answer to Problem 5P

The marginal product of hat in the cases with three and four machines are shown below:

    Labor (L)Total Product (TP)Marginal Product (MP)
    188
    21810
    33012
    44515
    55712
    66710
    7725
    Labor (L)Total Product (TP)Marginal Product (MP)
    199
    22011
    33515
    45520
    57621
    68812
    7957

Explanation of Solution

Marginal Product is the addition to total product when an extra unit of labor is employed. It is calculated as follows.

  MPn=TPnTPn1

Using the formula above, we calculate MP for 1st level of employment as follows:

  MPn=TPnTPn1MP1=TP1TP11MP1=TP1TP0MP1=80MP1=8

Similarly, we calculate MP for each level of employment in cases with three and four machines and MP schedule for both cases is shown below.

    Labor (L)Total Product (TP)Marginal Product (MP)

Economics Concept Introduction

Total Product (TP):

Total product is the total output that a firm produces by its production activities.

Marginal Product (MP):

Marginal Product is the addition to total product when an extra unit of a particular quantity.

Answer to Problem 5P

The diminishing marginal product sets in with three machines at 5th level of labor employment. The diminishing marginal product sets in with four machines at 6th level of labor employment.

Explanation of Solution

We have the TP and MP schedule for the cases with three machines and four machines as follows:

    Labor (L)Total Product (TP)Marginal Product (MP)
    188
    21810
    33012
    44515
    55712
    66710
    7725
    Labor (L)Total Product (TP)Marginal Product (MP)
    199
    22011
    33515
    45520
    57621
    68812
    7957

In the first case, marginal product starts to fall from L=5. While, in the second case, marginal product starts to fall from L=6. Therefore, the diminishing marginal product sets in with three machines at 5th level of labor employment and diminishing marginal product sets in with four machines at 6th level of labor employment.

The reasons why the points of diminishing marginal product are different in the two cases.

Explanation of Solution

Marginal Product is the addition to total product when an extra unit of labor is employed. Typically, marginal product first increases, reaches maximum, falls and finally becomes negative. In both the cases, the property of marginal product applies. However, the falling of marginal product is delayed with four machines because increasing one input (labor) with increase in another input (machines) makes marginal product higher. The marginal product of labor is higher at each step with four machines than that with three machines. Thus, with more number of machines, the diminishing returns to labor set in at a later stage. Therefore, the points of diminishing marginal product are different in the two cases.
