Quizplus · Accepted Answer

The marginal product of the fourth unit of labor when capital increases from 3 to 4 units is calculated by subtracting the total output with 3 units of capital from the total output with 4 units of capital, both at 4 units of labor. This is (164 - 148) = 16 units. However, the question asks for the marginal product of the fourth unit of labor, which is the difference in output due to the increase in capital for that specific unit of labor. The increase from 148 to 164 represents a 16 unit increase in total output, but the question's phrasing seems to aim at the incremental benefit of adding the fourth unit of labor with the increase in capital, which is not directly answered by the provided calculations. Given the options and the data, the correct interpretation aligns with an increase, and the closest direct calculation error seems to have occurred in the explanation process. The correct interpretation should focus on the increase in output due to the additional unit of capital for the fourth unit of labor, which is indeed 16 units, not directly offered in the options, indicating a potential misunderstanding in the explanation.
