Question

Quizplus · Accepted Answer

The value for B, which represents the marginal product of labor (MPP) for the 5th worker, can be determined by calculating the difference in total product (Q) between the 5th and 4th workers. The total product for the 5th worker is 38, and for the 4th worker, it is denoted as A. Given the pattern of increasing MPP before it starts to decrease, and knowing the MPP for the 4th worker is 9 and for the 6th worker is 12, the increase from the 4th to the 5th worker must be consistent with the pattern of increasing marginal returns before reaching a peak. Since the MPP for the 6th worker is 12, indicating an increase, the MPP for the 5th worker logically fits to be 11 to maintain the pattern of increasing marginal productivity before it starts to decline, aligning with the concept of diminishing marginal returns.
