if i understand your last few posts on this, you seem to be saying that the u.s.'s (for example) problems can all be solved by simply printing more money, lots more... there will either be inflation, in effect wiping out the debt, or not... if not (which seems impossible), the dollar stays high or goes higher, and there are more of them... unemployment would of necessity then drop
is that even close?
The point of rising inflation, is that it will lower unemployment. In a demand side recession, there is nothing `wrong' with the economy, but for some reason prices have gone wrong, so we can no longer exchange the stuff we are producing for the stuff that we want. In theory we should simply be able to reset the prices. In reality wages and prices are downwards sticky. It is not easy to convince people to take a pay cut. Inflation makes it easier to give people effective pay cuts, as holding wages steady is a pay cut. So in a demand side recession there is a direct trade off between the rate of inflation and the unemployment rate. This is called the Philip's curve (google it).
Lowering unemployment should be the first goal in a recession, as putting people back to work will raise national output, and is generally a good thing. Also, it is difficult for inflation to rise much when the output is increasing, as the money supply has to rise faster than the output in order to cause inflation. What happens in reality, is that the central bank attempts to cause inflation by printing money, this puts people back to work, and the rate of inflation starts to rise only after unemployment is close to its natural rate, at which point the trade off becomes less. When you are at the natural rate, no amount of inflation will achieve a reduction in unemployment.
It appears, that central bankers believe that `price stability' is a more important goal that reducing unemployment. This is bananas.
However, there is a second argument sometimes advanced by left wing commentators, e.g. Krugman, that we need fiscal policy (i.e. government spending) in order to reduce unemployment. The believe that monetary policy is ineffective when interest rates are zero, since the traditional way for a central bank to expand the money supply is by buying treasuries, but zero coupon treasuries are identical to hard cash, so this becomes less effective at low interest rates. This is called, variously, the zero bound, the liquidity trap, ZIRP, and other things, but basically the thrust of their argument is that the central bank cannot, under these circumstances, cause inflation. This is also bananas. For one thing, if it is true, the central bank could buy up every US treasury and give them back to the US government, and say "look, don't bother paying us back, theres no need, we can print this money for free anyhow". Krugman seems to believe that doing this would not cause any inflation, and would therefore not achieve anything. If this were the case, the central bank could buy up every piece of personal, private or government bond or debt with newly minted cash, and retire them, for free. So it should clearly do that.
On the other hand, if like me, you believe that the central bank can cause inflation even at the lower bound, then we are back to reducing unemployment. They should clearly engage in monetary stimulus to lower unemployment back to the natural rate (5-6% for the US). Central banks are choosing high unemployment and recession.
My understanding is that they misunderstand the distinction between supply side and demand side problems, and therefore do not believe that raising inflation would lower unemployment. This is what happened in the 1970's. in that case they tried to lower unemployment by raising inflation, but that did not work,because supply side problems are `real' problems, and cannot be fixed or alleviated by fiddling with monetary policy. Supply side problems are easy to understand in principle: Suppose that an asteroid destroyed half of the united states, and half of its productive capacity (eg factories) but you managed to save all of the people by evacuating them. In this case it is clearly absurd to believe that causing inflation will lead to rapid return of unemployment to 5%. In truth we would need to rebuild all of the factories, farms, cities, etc. This is what happened in the 1970's, except there was a rapidly expanding population (faster than you could build factories), coupled with a restricted supply of commodities, (which caused their prices, especially oil, to rise).
The pessimistic reading is that they do understand perfectly well, they just would rather protect the rich than lower unemployment. I never assume malice where stupidity is sufficient, but there we go.
