The marginal product of labor eventually slopes downward due to the law of diminishing marginal productivity. The law of diminishing marginal productivity is a principle within economics. This principle states even if you increase input in one area and keep the others the same, output does increase, there will be limited effect and eventually balance back out resulting in no effect on the output.
