Chapter 11. Question 16

Correct! The marginal physical product is the additional output produced when one more worker is hired. Since the first 5 workers produce 250 units of output, and six workers produce 270 units, the sixth worker increased output by 20 units (270 – 250).

Incorrect! The marginal physical product is the additional output produced when one more worker is hired. Since the first 5 workers produce 250 units of output, and six workers produce 270 units, the sixth worker increased output by 20 units (270 – 250).

Correct! The marginal revenue product is the dollar value of a worker’s marginal physical product. In this case, the marginal product is 20 units, and since each unit is worth $10, the marginal revenue product is 20 x $10 = $200.

Incorrect! The marginal revenue product is the dollar value of a worker’s marginal physical product. In this case, the marginal product is 20 units, and since each unit is worth $10, the marginal revenue product is 20 x $10 = $200.

Correct! It is profitable to hire an additional worker if the marginal benefit is greater than the marginal cost. Here, the sixth worker contributes $200 worth of revenue, but costs only $150. The employer receives ($200 – $150) = $50 more when the sixth worker is hired.
