It turns out that supply curves are really just marginal cost curves.

事实证明，供给曲线实际上就是边际成本曲线。

The result is the entire supply curve is gonna shift to the left.

结果是整个供给曲线会向左平移。

That's called the law of supply, and on the graph it's shown by an upward sloping supply curve.

这就是供给定律，图表上显示的是向上倾斜的供给曲线。

They do not seem to have realised that, unless the supply of labour is a function of real wages alone, their supply curve for labour will shift bodily with every movement of prices.

他们似乎没有意识到，除非劳动力供给仅仅是实际工资的函数，否则他们的劳动力供给曲线将随着价格的每一次变动而发生明显的变化。

In the same way the ordinary supply curve for a particular commodity is drawn on some assumption as to the output of industry as a whole and is liable to change if the aggregate output of industry is changed.

以同样的方式，特定商品的普通供给曲线是根据对整个工业产出的某种假设绘制的，并且如果工业总产出发生变化，则该曲线可能会发生变化。
