Thus, if additional demand is directed to them without notice, they will show a low elasticity of employment; although it may be that, given sufficient notice, their elasticity of employment approaches unity.

因此，如果在没有通知的情况下向他们提出额外需求，他们将表现出较低的就业弹性；尽管有可能，给予足够的关注，他们的就业弹性接近统一。

The neutral rate of interest can be more strictly defined as the rate of interest which prevails in equilibrium when output and employment are such that the elasticity of employment as a whole is zero.

中性利率可以更严格地定义为当产出和就业使得整个就业的弹性为零时处于均衡状态的利率。

In the same way employment may fall off without there having been any change in aggregate demand, if the direction of demand is changed in favour of products having a relatively low elasticity of employment.

同样，如果需求方向发生变化，有利于就业弹性相对较低的产品，则就业可能会下降，而总需求没有任何变化。

A product, I should prefer to say, has a period of production n if n time-units of notice of changes in the demand for it have to be given if it is to offer its maximum elasticity of employment.

我宁愿说，如果要提供最大的就业弹性，就必须给出 n 个时间单位的需求变化通知，那么产品的生产周期为 n。

Thus if the first impulse towards the increase in effective demand comes from an increase in consumption, the initial elasticity of employment will be further below its eventual equilibrium-level than if the impulse comes from an increase in investment.

因此，如果有效需求增加的第一个推动力来自消费的增加，那么与来自投资增加的推动力相比，就业的初始弹性将进一步低于其最终均衡水平。

If, for example, the increased demand is largely directed towards products which have a high elasticity of employment, the aggregate increase in employment will be greater than if it is largely directed towards products which have a low elasticity of employment.

例如，如果增加的需求主要针对具有高就业弹性的产品，则就业的总体增长将大于主要针对具有低就业弹性的产品的情况。
