Thanks for that post - now that's something to work with!
The Gross World Product (GWP) is currently around 80 trillion US$. (That's a US trillion, a British billion.)
Wouldn't the GWP be all the money the world economy turned over in a given period of time? How is that related to M2, M3 or whatever?
When you got some money on your account or under your mattress, it counts for the M's, but doesn't do anything, so doesn't count for the GWP.
You're right. Monetary Base (MB) is probably the best bet to figure this out. MB of the US is supposedly $3,736,101,000,000. What about the world?
