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。

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。

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。
