Krugman has been saying that the stimulus didn't work because it wasn't big enough. In a recent blog, he answers his critics who charge that a bigger stimulus will result in high inflation.
The data back up Krugman, in that commodity prices haven't risen significantly (see post copied below).
There are 2 opposing forces . . . debasement of the dollar by "printing" and demand destruction by unemployment and general economic slowdown. The latter is why commodity prices have not risen. But if there is a shift in the ratio of these opposing forces, things will change.
But even if input (commodity) costs haven't risen, there are businessmen who raise prices in order to maintain their own standard of living in the face of lower sales . . . so we can have both a rise in consumer prices and no rise in commodities. But there is a limit of how high prices can go in face of declining demand. (Note: demand can go down even with essentials like food and energy, as people drive less and eat cheaper foods.)
Also interesting . . . .
Krugman says, " . . . very old dictionaries defined inflation as a rise in money and/or credit, but the modern usage is, of course, a rise in prices." It seems like Mish's definition of inflation is more "classic".

Way Off Base
I see some commenters reacting to the failure of major inflation to break out by insisting that inflation is defined as an increase in the monetary base — that is, the bank reserves plus currency that are what increases when the Fed “prints money”. As it happens, that’s wrong: very old dictionaries defined inflation as a rise in money and/or credit, but the modern usage is, of course, a rise in prices.
But that’s really a side issue. Nobody would care about the size of the monetary base except for the belief that increasing the base leads to a rise in prices. That’s not a question of definitions, it’s a question of your model of the economy. The underlying belief of all the people accusing Ben Bernanke of doing something dastardly is that “printing money” has caused or will cause high inflation in the ordinary sense.
The thing is, of course, that the past three years — the post-Lehman era during which the Fed presided over a tripling of the monetary base — have been an excellent test of that model, which has failed with flying colors. Here are the data — I’ve included commodity prices (IMF index) as well as consumer prices for the people who believe that the BLS is hiding true inflation (which it isn’t):

A couple of notes: for the commodity prices it matters which month you start, because they dropped sharply between August and September 2008. I use the IMF index for convenience– easy to download. (Thomson Reuters I use when I just want to snatch a picture from Bloomberg). But none of this should matter: when you triple the monetary base, the resulting inflation shouldn’t be something that depends on the fine details — unless the model is completely wrong.
And the model is completely wrong. You don’t get more conclusive tests than this in economics. By contrast, the model of an economy in a liquidity trap, in which big increases in the monetary base don’t matter, comes through just fine.
And this in turn tells you something about the people pushing this stuff. They had a model; it made predictions; the predictions were utterly, totally wrong; and they have just dug in further.
