I clicked Random Eyes (see sidebar), then clicked

*random*a few times and ended up with M2 velocity:

Those dates ring a bell for ya? They do for me. That was the time of a strong increase in M1 money growth, and a fall in the debt-per-dollar ratio. With a strong increase in M1 growth, I think M1 velocity probably fell -- just the opposite of M2 velocity. That's odd, if true, and it's worth a look:

Sure enough, beginning in the first quarter of 1991, M1 velocity (red) trends down while M2 velocity (blue) trends sharply up. M1 continues down to fourth quarter 1993; M2 continues up till first quarter 1995.

Velocity of money is calculated by dividing GDP by the quantity-of-money number. GDP is GDP, the same for the red line and the blue. So the difference between the two lines is due to differences in the M1 and M2 money numbers. Compare growth rates:

There was a change in M1 accounting in 1994 that reduced the amount of money

*reported*as M1 money:

Sweep programs create distortions between reported data on the monetary aggregates and accurate measures of the money stock.

In order to correct for these distortions, Graph #4 duplicates Graph #3 using M1 that has "sweeps" added back in:

Graph #4: Growth Rates of M1 + Sweeps (red) and M2 (blue) Money |

To see the difference in growth rates, I took the two lines from Graph #4 and subtracted the one from the other. I'm trying to see how much faster (or slower) the one money measure was growing, than the other. I subtracted M2 from M1. That means that when the difference is above zero M1 is growing faster, and when the difference is below zero M2 is growing faster:

The big gains for M1 show up as large mid-1980s and early-1990s peaks on Graph #5. There are two much smaller peaks in the 2000s, and some unevaluable activity since 2008. Other than that, the blue line is almost always below the zero-line: M2 almost always was growing faster than M1.

What makes this more interesting is that M1 money is a component of M2 money. If you take M2 and split it into the money we expect to spend and the money we hope to save, M1 is the part we expect to spend. The rest is money we're trying to save. So basically, Graph #5 shows that our savings have almost always grown faster than our spending-money, except during those two massive spikes and a few brief interludes.

If you take Potential GDP, which is a measure of best-case GDP, and put its growth rate on Graph #5, it looks like this:

Why? Because no matter what you want to do in this economy of ours, it takes spending money to do it.

Thinking about all that, I remembered some things Jim said a while back:

The bulge in growth of M1 that you show ... seems to me to be due to the fact that in the late 80's banks started to pay interest on checking accounts ... But in order to get that interest one had to keep a minimum of $500 in one's checking account. So lots of people moved money from savings to checking..."
