If we suppose the volume of output to be given, i.e.

如果我们假设输出量是给定的， 即。

I there argued that change in the excess of investment over saving was the motive force governing changes in the volume of output.

我在那里争论说， 投资超过储蓄的变化是支配产出量变化的动力。

Why should the volume of output and employment be more intimately bound up with the money-rate of interest than with the wheat-rate of interest or the house-rate of interest?

为什么产出和就业量与货币利率的关系比与小麦利率或房屋利率的关系更密切？

But if our central controls succeed in establishing an aggregate volume of output corresponding to full employment as nearly as is practicable, the classical theory comes into its own again from this point onwards.

但是，如果我们的中央控制成功地建立了一个尽可能接近充分就业的总产出量， 那么经典理论将从这一点开始再次发挥作用。

Thus Say's law, that the aggregate demand price of output as a whole is equal to its aggregate supply price for all volumes of output, is equivalent to the proposition that there is no obstacle to full employment.

因此，萨伊定律，即作为一个整体的产出的总需求价格等于其对所有产出量的总供给价格，等同于充分就业没有障碍的命题。

It follows that for any given volume of output of the product in question there is a corresponding user cost, but that this total user cost does not bear a uniform relation to the marginal user cost, i.e.

因此，对于所讨论产品的任何给定产量，都有相应的用户成本，但总用户成本与边际用户成本不具有统一的关系，即。
