Diminishing marginal returns first appear with the third unit of labor. As the number of workers increases from 2 to 3, the marginal product of labor increases from 50 to 60. However, as the number of workers increases from 3 to 4, the marginal product of labor decreases from 60 to 55, indicating the onset of diminishing marginal returns.
