I think I've identified the broader issue here. You're assuming Y*. You're assuming we're always at Y*. Stop assuming we're at Y*I believe monetary neutrality holds in the long run.
High aggregate demand, and the inflation it brings, does provide you with "the good life" but only in the short run before higher inflation expectations are "built in". The good life comes from stable aggregate demand, and more importantly, increasing aggregate supply.

For those of you spectating, Y* is Y-star or Y-prime, it means equilibrium.
Already dubious that Y* is even a thing because equilibrium is a bit of a dodgy macroeconomic concept. But just assuming it means full employment, which it's meant to, we already know that it doesn't get there and stay there on its own. This is the lynchpin of why macroeconomics even exists: microeconomic equilibrium models don't scale up to the macroeconomy. Primarily because business as a rule underinvests.
The problem here is that the model you're using holds constant virtually everything, starting us at Y*, so a bump in employment driving inflation is the same as a bump in inflation driving employment, which is unsustainable and really just a temporary distortion.
But that's a bit of switcharoo, because holding all things constant, we're able to dodge causation. But if we have unemployed people now, and unemployed capital now, and we employ those people, that drives real gains. If we overshot, which means that we're throwing more money at folks than is needed to get that employment, then some of those gains will not be real gains, merely nominal gains. But there will still be real gains, because the difference between employing them and not employing them is a real difference.
The point being that we can worry "oh no inflation will steal my wages" but that inflation will only negate a fraction of the surplus wages that caused the unemployment in the first place.
See the difference there? That's pretty important.
I think NAIRU is generally poorly calculated as most inflation spikes in this country has been supply side and yet aren't often treated as such. The inflation we were seeing just before the crash was not being brought on by the 4.5% unemployment (4.5% consisting of part time jobs and low wages should have been the tip off. Worst. recovery. ever.) but that oil prices via speculation were reaching 70s levels and it was hitting the mainstream economy fast.Earlier you said "The number of years we've been genuinely running up against full employment in the last century is probably like 8, mostly during world-war time." If you're defining "full employment" as the non-accelerating inflation rate of unemployment then you must think NAIRU is really low.
But I also think that NAIRU is, in addition to being obviously moving target based on supply price shocks etc is also a function of a lot of variables that we have some control over. And while it's not in the literature AFAIK because my ideas are not literature yet

Of course it didn't, because you can't spend past supply limits. But you can play at the margins. Hyperinflation is counter productive but say it theoretically wasn't--that it was just vastly marginally diminished in effectiveness--that meant that Zimbabwe was not solving the supply shock unemployment but shoring up the margins. So if 20% (made up) unemployment was full employment due to farm appropriations, hyperinflationary spending is used to drive unemployment down to 20% from 20.04%, just to make sure enough people were eating so that the party had a few more votes come election. But, the flip side is that not driving spending increases in the face of a supply shock may have had unemployment at 24%, which is legitimately a lot higher.Yes, the scenarios did have a supply shock that triggered them. My point is when Zimbabwe reached a peak of over 79,600,000,000% inflation per month it was demand-driven, and aggregate demand growth in the 11 or 12 digits didn't wipe out unemployment.
Remember, the hyperinflation is the result of a political move to prevent the economy from losing output best as possible. People don't like to move backward in life. Governments know this, or they don't succeed in being governments. But that's different than going forward.
Fiscal policy can change the natural rate because fiscal policy can change the fundamental nature of our economy, but let's pretend it can't.You've misinterpreted. I only mean that fiscal policy is irrelevant for managing aggregate demand. I see the goal of "2-6% inflation and 3% unemployment + real rising wage levels" as being a matter of managing aggregate demand. I don't know how fiscal policy would lower the "natural" unemployment rate although if that's possible I'm all for it.
That's still a far leap from saying fiscal policy is irrelevant for managing aggregate demand. That's gotta be the weirdest thing I've read in a long while. Honestly the only people I know who write that kind of stuff are people who deny aggregate demand even exists. Those people are crazy man, don't be one of them! (I jest I jest!)
Remember, this branch of discussion stems from is your claim of monetary offset in the way you claimed it. But monetary policy is far weaker than fiscal policy even without the zero lower bound limitation. We didn't win WW2 by cutting interest rates. Government bought war machines with cash. (BTW, peep this: very likely if we keep using IS-MP (IS-LM) next generation we're going to set the MP curve horizontal--aka that all interest rates follow liquidity trap logic to a large degree. That will be an exciting day in the field.)
And monetary policy is a choice, the same as how fiscal policy is a choice. And when MP fails to work, FP is an obvious answer. This brings us back to the point of the topic, which is asking what's wrong with the debt. The debt is the political reason that we don't use our economic policy solutions to our economic problems.
That's almost the theory. We haven't done (almost the) it since Volcker though, Greenspan was no better. But central banks are not forced to raise interest rates, they choose to raise interest rates. And if they're really trying to hold back aggregate demand doesn't that makes them the bad guys? Like I said, trying to pop bubbles by raising interest rates is a rookie mistake, it does loads of harm to the real economy that isn't a matter of popping the bubble but a matter of stifling actual demand first which in turn pops the bubble which is just a terrible terrible way of doing it.The central banks are forced to raise their interest rates during the peak of a business cycle because demand for credit is rising and if they don't raise rates aggregate demand will get too high. Likewise they're forced to lower rates at the trough of a business cycle or else they would make things worse. So it's the business cycle that's driving interest rates. If the Fed finds they need low interest rate targets, it's a legacy of money being too tight in the past, and vice versa.
Let's remember this part came from your stating that there's not "just one interest rate". Ping pong is fun but let's keep it on the board. Maybe we can consolidate?
I know, it seems crazy once it's put that way. That's why I was asking you to explain it. Here's what you said.Where did I say that the central bank could boost aggregate demand by buying treasury bonds from the treasury but not by buying them from banks who bought them from the treasury...? If we were truly in a "liquidity trap" then the government could continue issuing bonds even when no one is willing to lend to the government without causing inflation, up to the point where we're no longer in a liquidity trap.
If the system stopped working, and the Federal Reserve started buying all the bonds that private individuals aren't willing to buy from the government, the increase in aggregate demand would lead to high inflation. This would violate the dual mandate the Federal Reserve is supposed to follow. If the government desires price stability, then it has to accept that there are limits on how much money it can spend.

Treasuries are the heavy metals, because they're the dollars that are fully insured. Actually that makes them better than gold because gold is the one based on confidence in gold. Dollars are based on something, however, and that's taxation. Taxation creates demand for dollars.I don't get this either. Maybe it was when dollars were backed by heavy metals. But now dollars are heavy metals. Which means they have arbitrary value all of their own, based entirely on confidence. Biggest main differences are dollars are easier to transport since their physical manifestation is less cumbersome and the treasury can mine them in an entirely more controllable format?
Bit of a sleight of hand there, you turned debt instrument into debt promise. It's why "debt" is such a misleading term in macroeconomics. It just means that on the macroeconomic ledger, every dollar that's a private sector asset is a government sector liability. Double entry bookkeeping. That's all this is--everything has to sum to 0.You'll have a hard time convincing people that "Every dollar they own is a debt instrument of the US of A". What's it a debt promise of? They'll give you a new dollar bill if you give them an old one?
