The insufficiency of effective demand will inhibit the process of production in spite of the fact that the marginal product of labour still exceeds in value the marginal disutility of employment.

尽管劳动的边际产品在价值上仍然超过就业的边际负效用，但有效需求的不足将抑制生产过程。

So long, indeed, as this proposition holds, any means of increasing employment must lead at the same time to a diminution of the marginal product and hence of the rate of wages measured in terms of this product.

事实上，只要这个命题成立，任何增加就业的方法都必须同时导致边际产品的减少，从而导致以该产品衡量的工资率的减少。
