Graphing the Economy

I was poking around on the Federal Reserve’s very useful collection of data, and came across these interesting graphs:

This one I’m guessing is the total reserves of Fed member banks. I wonder where all the money in the stock market went?

This one is roughly equivalent to the money supply. Inflation? What inflation?
http://research.stlouisfed.org/fred2/series/BASE?cid=124

Ooh. Ooh. Found another one. Total borrowings of banks from the Fed.

Liquidity problem? What liquidity problem?

Now, I’ve seen the line at the right of all these graphs somewhere before. Oh yes, electrical engineering, control systems theory. It’s an impulse function, the theoretical input to a feedback loop. Expect some economic oscillation ahead…
