Don't They Know Ayn Rand Wrote Fiction?

Economics and Politics - Paul Krugman Blog -
"Keynesian economics won, hands down."

So: first of all, the other side in this debate generally adheres, more or less, to something like what Keynes called the “classical theory” of employment, in which employment and output are basically determined by the supply side. Casey Mulligan has been most explicit here, coming up with increasingly, um, creative stories about how what we’re seeing is a choice by workers to work less; but the whole Kocherlakota structural unemployment thing is similar in its implications.

Oh, and the Cochrane-Fama thing about how a dollar of government spending necessarily displaces a dollar of private spending is basically a classical view, although there doesn’t seem to be a model behind it, just a misunderstanding of what accounting identities mean.

Once you have a more or less classical view of unemployment, you naturally have the classical theory of the interest rate, in which it’s all about supply and demand for funds, and something like a quantity theory of money, in which increases in the monetary base lead, in a fairly short time, to equal proportional rises in the price level. This led to the prediction that large fiscal deficits would lead to soaring interest rates, and that the large rise in the monetary base due to Fed expansion would lead to high inflation.

You can see the classical theory of interest and the soaring-rate prediction clearly in Niall Ferguson’s remarks:

After all, $1.75 trillion is an awful lot of freshly minted treasuries to land on the bond market at a time of recession, and I still don’t quite know who is going to buy them … I predict, in the weeks and months ahead, a very painful tug-of-war between our monetary policy and our fiscal policy as the markets realize just what a vast quantity of bonds are going to have to be absorbed by the financial system this year. That will tend to drive the price of the bonds down, and drive up interest rates

and, of course, in many WSJ op-eds, in analyses from Morgan Stanley, and so on.

Meanwhile, you can see the high-inflation prediction in pieces by Meltzer andLaffer — with the latter helpfully titled, “Get Ready for Inflation and Higher Interest Rates”.…

So, how has it turned out? The 10-year bond rate is about 2.5 percent, lower than it was when Ferguson made that prediction. Inflation keeps falling. The attacks on Keynesianism now come down to “but unemployment has stayed high!” which proves nothing — especially because if you took a Keynesian view seriously, it suggested even given what we knew in early 2009 that the stimulus was much too small to restore full employment.

Their theories are just plain nuts.

They never, ever, let reality get in the way of belief.

So, they ‘pledge’ to return to faith based economics, to unleash business via faith based nonregulation and they'll pay down the deficit with faith based income.

The hungry will eat by and by, work all day, live on hay. There'll be pie in the sky when they die.

Not much while they live, but man doesn't live by bread alone!
