1 From "That guy is quite the hardcore Keynesian," (point of order, Kimball describes himself as a "neo-Monetarist," whatever that might be) "That's only if you accept Keynesian theory from the outset. Also, if basic Keynesian theory were correct," and "Pure Keynesian theory is obnoxious." If the impression taken from those quotes is incorrect, I'll discard it.
2 Yes, it's quite a bane for the science. See
here,
here, and
here. But let's not be too harsh on Mankiw, he did write
this, which sounds good to me.
3 This is a monstrous lie. There is just about no relationship between the change in the money supply and the change in the CPI in the short term.
The quarterly change in M2 money has a -.05 correlation coefficient with inflation. If we think price setters take a while to adjust to the money supply, lagging the change in money supply one quarter produces a -.089 correlation. This is not a convincing case that printing -> inflation.
Likewise, there is almost no relationship whatsoever between the change in M1 and the inflation rate (-.01 correlation). I don't know who told you that the money supply is the greatest factor in inflation, but I'd suggest never listening to that person again. I mean, that idea is just wrong, except for Zimbabwe or other similarly insane situations. There's nothing to support it in the United States' case and there's no excuse for holding it, as it totally ignores the lesson of price instability under the Gold Standard. Inflation is determined by demand pushing up against the limits of supply. Right now we don't have demand stressing supply, and so we don't have inflation even with a ton of money (more reason to assume we haven't had enough stimulus). In the 1990s we have a big rise in productivity, and therefore supply, that coincided with a period of high demand and so we didn't have bad inflation. Score one for economy-wide models like AD-LRAS. That's a hell of a lot more explanatory and predictive power than assuming that the money supply determines inflation. Also check out the charts on the fourth page of
this report.
I mean, why do you think Volcker's recessions were necessary to break the inflation fever? He didn't destroy any M1 money and the M2 series only starts in November 1980 so I can't see any changes. The recessions squelched demand and hence inflation/inflation expectations. Once the expectations were dead he could allow demand to pick up again, with relatively smooth growth in the money supply.
4 Because [drumroll], the Fed expects the shitty conditions to last until late 2014.
5 Two points. One, someone is being paid to build that capital. And two...
6 This is the paradox of toil in action. The capital substitutions push out AS and do nothing to restore AD, assuming, reasonably, that the capital substitution is being undertaken because it is cheaper than hiring new workers (the worker in the previous point is cheaper than the new hire). The way to restore demand is by stimulating demand, not by fiddling with aggregate supply. And that's exactly how the paradox of toil is intuitive, a collapse in demand got us into this Little Depression and demand will need to be re-inflated in order to get us out.
7 The President doesn't control the Fed's independence, Congress does. The President has hardly uttered a peep about the Fed, meanwhile the House GOP is doing its damnedest to audit the Fed, the GOP
is going to put a plank in the platform about exploring reviving the Gold Standard, and it's VP nominee takes his monetary policy from some crank in a romance novel who was apparently a pretty disagreeable guest at someone's wedding reception. We're going to have to agree to disagree here, given that you hold your view without a shred of publicly-available evidence to support it.
8 You asked why I preferred spending increases to tax cuts. I believe that spending is less sticky than tax rates are and would end more quickly once demand is restored, so I support spending as the stimulative measure. The fact that our deficits haven't been big enough doesn't change that.
