Question

Quizplus · Accepted Answer

The marginal product of labour is the additional output resulting from a one-unit increase in labour, which is not equivalent to the total product divided by total labour (as stated in option D). The correct option is A, which correctly defines the marginal product of labour. Option B is also correct, as the slope of the total product curve represents the change in output per unit change in labour. Option C is also correct, as the marginal product of labour can vary depending on the level of input, and can even become negative when the returns to scale diminish.
