(i) The national dividend, as defined by Marshall and Professor Pigou, measures the volume of current output or real income and not the value of output or money-income.

(i) 按照马歇尔和庇古教授的定义，国家红利衡量的是当前产出或实际收入的数量，而不是产出或货币收入的价值。

Thus it is not logically impossible that there should be a commodity in terms of which the value of output is expected to be more stable than in terms of money.

因此，从逻辑上讲， 存在一种商品， 其产出价值比货币价值更稳定， 这在逻辑上并非不可能。
