At the cost of anticipating what is more properly the subject of chapter 21 below it may be interesting briefly at this stage to indicate the relationship of the above to the quantity theory of money.

以预测下面第 21 章更恰当的主题为代价，在此阶段简要说明上述内容与货币数量论的关系可能很有趣。

We have reached, that is to say, a situation in which the crude quantity theory of money (interpreting 'velocity' to mean 'income-velocity') is fully satisfied; for output does not alter and prices rise in exact proportion to MV.

也就是说，我们已经达到了一种情况，在这种情况下，货币的粗略数量理论（将“速度”解释为“收入速度”）是完全满足的；因为产量不变，价格上涨与 MV 成正比。
