We shall return to the aggregate supply function in chapter 20, where we discuss its inverse under the name of the employment function.

我们将在第 20 章回到总供给函数，在就业函数的名称下讨论它的反函数。

The aggregate supply function, however, which depends in the main on the physical conditions of supply, involves few considerations which are not already familiar.

然而，总供给函数主要取决于供给的物理条件， 涉及一些不为人所知的考虑因素。

(5) Hence the volume of employment in equilibrium depends on (i) the aggregate supply function, (ii) the propensity to consume, and (iii) the volume of investment, D2.

(5) 因此， 均衡的就业量取决于 (i) 总供给函数， (ii) 消费倾向， 以及 (iii) 投资量 D2。

The value of D at the point of the aggregate demand function, where it is intersected by the aggregate supply function, will be called the effective demand.

总需求函数与总供给函数相交点处的 D 值称为有效需求。

So far we have established the preliminary conclusion that the volume of employment is determined by the point of intersection of the aggregate supply function with the aggregate demand function.

至此，我们初步建立了就业量由总供给函数与总需求函数的交点决定的结论。

Finally, they furnish us with the supply function of labour (or effort); so that they tell us inter alia at what point the employment function for labour as a whole will cease to be elastic.

最后，它们为我们提供了劳动（或努力）的供给函数；因此，他们特别告诉我们整个劳动力的就业函数在什么时候将不再具有弹性。

To determine the quantity of employment, Professor Pigou then combines with his 'real demand for labour', a supply function for labour. He assumes that this is a function of the real wage and of nothing else.

为了确定就业数量，庇古教授结合了他的“劳动力实际需求”，即劳动力供给函数。他假设这是实际工资的函数，仅此而已。

The purpose of the concept of the elasticity of the real demand for labour in the aggregate is to show by how much full employment will rise or fall corresponding to a given shift in the supply function of labour.

总劳动力实际需求弹性概念的目的是表明，随着劳动力供给函数的给定变化，充分就业将增加或减少多少。
