    en.wikipedia.org/wiki/Marginal_product_of_labor

    Marginal cost (MC) is the change in total cost per unit change in output or ∆ C /∆ Q. In the short run, production can be varied only by changing the variable input. Thus only variable costs change as output increases: ∆ C = ∆ VC = ∆ ( wL ). Marginal cost is ∆ ( Lw )/∆ Q. Now, ∆ L /∆ Q is the reciprocal of the marginal product ...

[ 1] In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an ...
