To answer this question, we actually have to have a proper theory of value.

要回答这个问题，我们其实需要一个恰当的价值理论。

User cost has, I think, an importance for the classical theory of value which has been overlooked.

我认为，用户成本对于被忽视的经典价值理论具有重要意义。

Now in the modern theory of value it has been a usual practice to equate the short-period supply price to the marginal factor cost alone.

现在，在现代价值理论中，通常的做法是将短期供应价格单独等同于边际要素成本。

The division of economics between the theory of value and distribution on the one hand and the theory of money on the other hand is, I think, a false division.

我认为，将经济学一方面划分为价值和分配理论，另一方面划分为货币理论，这是错误的划分。

But, although the theory of shifting equilibrium must necessarily be pursued in terms of a monetary economy, it remains a theory of value and distribution and not a separate 'theory of money'.

但是，尽管移动均衡理论必须从货币经济的角度进行研究，但它仍然是一种价值和分配理论，而不是一种单独的“货币理论”。

One of the objects of the foregoing chapters has been to escape from this double life and to bring the theory of prices as a whole back to close contact with the theory of value.

前面几章的目标之一就是摆脱这种双重生活，使价格理论作为一个整体重新与价值理论密切联系。

Thus the classical school have had quite a different theory of the rate of interest in volume I dealing with the theory of value from what they have had in volume II dealing with the theory of money.

因此，古典学派在涉及价值理论的第一卷中的利率理论与他们在涉及货币理论的第二卷中的利率理论截然不同。
