Ordinarily speaking, the public will not do this unless their aggregate income in terms of wage-units is increasing.

一般而言，除非以工资单位计算的总收入增加，否则市民不会这样做。

Up to this point, however, rising prices will be associated with an increasing aggregate real income.

然而，到目前为止，价格上涨将与实际总收入的增加相关联。

This means that, if employment and hence aggregate income increase, not all the additional employment will be required to satisfy the needs of additional consumption.

这意味着，如果就业和总收入增加， 并不是所有的额外就业都需要满足额外消费的需求。

That is to say, consumption will depend on the level of aggregate income and, therefore, on the level of employment N, except when there is some change in the propensity to consume.

也就是说，消费将取决于总收入水平，因此也取决于就业水平 N，除非消费倾向发生某些变化。
