Under the MMM theory, the government spends ALL money into existence. So by default, consumers cannot cause inflation, because that would imply they have excess money to chase fewer goods/services, but that excesss had to first come from excess government spending (which is probably only known in hindsight).moda0306 wrote: Spending in excess of capacity causes the inflation... it doesn't matter if it's gov't or consumers... though gov't is more likely to spend in excess of capacity.
If you were to see a huge destruction of our productive capacity, let's say massive earth quakes, and the gov't didn't spend one extra dime, but people demanded just as much in goods/services, inflation would hit hard, as this would be an example of demand in excess of a newly low level of productive capacity.
Now that is completely different than "inflationary" supply/demand imbalances which are not dependent on government-created money being in excess.
Gumby seems to believe that consumer spending causes inflation, whereas consumers do not create any money in the first place, nevermind an excess. Consumer spending will always be constrained by government spending, it is not a chicken and egg question, it's cat (government) and mouse (consumer). If he wants to argue that increased consumer demand creates decreased supply, that is an entirely different issue that is not related to the velocity of money. But, he was arguing for the Philips Curve which maintains there is a tradeoff between inflation and unemployment. It was discredited in the 70's during stagflation. Saying that consumer spending is inflationary is conflating cause and effect. Money is simply not necessary to create increased demand or decreased supply.
Again, INFLATION = GOVERNMENT SPENDING + CHANGE IN VELOCITY OF MONEY - PRODUCTIVE OUTPUT.
Take Japan for example. It has relentless government spending, stable productive output and a low velocity of money (and varying consumer demand). Very similar to the USA at present. There will be no inflation in the system until the velocity of money increases. Velocity of money does not increase if people demand more than there is a supply of fixed goods/services, it only increases when it is necessary to maintain equilibirum with other assets.
For example, for gold to maintain equilibrium with other competitive assets, the other assets have to have negative real returns because of gold's carrying costs, etc..
Velocity reflects the supply and demand for money itself. Money responds to the same supply and demand laws as any other asset. If newly issued Treasury Bonds offer a higher rate of interest than off the run Treasury bonds, bank reserves, savings, M0, M1, blah blah blah, velocity will increase as everyone will want to get rid of the old lower, rate for the new, higher rate. Inflation will then manifest. This is the same situation that cause gold to collapse, i.e. real rates rising.
In summary, inflation is a FISCAL phenomenom, NOT monetary and NOT demand side.
