The diminishing marginal product of labor exists when the last worker hired produces "less output than the previous worker".
The law of diminishing marginal productivity is an economic standard. It expresses that while expanding one information and keeping different contributions at a similar dimension may at first increment yield, further increments in that information will have a constrained impact and will in the end have no impact, or a negative impact, on yield. The law of diminishing marginal productivity clarifies why expanding creation isn't generally the most ideal approach to build profitability.
