So, I looked at Friedmans graphs. I found this sentence striking:
>booms do not tend to cause recession of equal intensity, which is what would be required by the ABCT and similar business cycles
Honestly, why would they be equal? GNP is not a direct measure of wealth. For one, even blatantly unproductive transactions drive it up. Expenses by the state enter it at their nominal value, even if they were a mistake from a financial standpoint. That is for one. Meanwhile, services that clearly have value, but one that isn't expressed in monetary terms, do not enter it. It is not a perfect representation of the state of the economy. To treat it as such is wishful thinking.
Furthermore, there are, at any given moment, millions of factors driving GNP up or down. The same is true of most economic indexes. To expect a proportional relationship between two factors to be visible in the GNP, when millions of factors enter it, is not to know what GNP is.
Now, when I look at figure 1, I can see that every trough is preceeded by a peak. Certainly, the peak is not nearly as prominent, but it's always there.
I'll leave the rest of the interpretation to other anons. Perhaps some that have more of a background in statistical analysis.
