The same observations apply mutatis mutandis to the case of a boom.

同样的观察也适用于繁荣的情况。

The same reasons as those mentioned above, which limit the efficacy of increases in the quantity of money as a means of increasing investment to the optimum figure, apply mutatis mutandis to wage reductions.

与上述相同的理由，将增加货币数量作为增加投资的手段的功效限制在最佳数字，适用于减薪。

Thus the inevitable price-instability due to change cannot affect the actions of entrepreneurs, but merely directs a de facto windfall of wealth into the laps of the lucky ones (mutatis mutandis when the supposed change is in the other direction).

因此，由于变化而不可避免的价格不稳定不会影响企业家的行为，而只会将事实上的意外财富转移到幸运者的圈中（当假设的变化是在另一个方向时，经过必要的必要修正）。
