At
least this is my version of MMT. Hopefully other MMTers will agree.
1.
Private sector spending varies with the stock of what MMTers call “Private
Sector Net Financial Assets” (PSNFA): that’s the stock of base money plus
national debt.
I.e.
in plain English, the more money (or near money, which is what government debt
is) that people hold, the more they tend to spend.
2.
If aggregate spending, i.e. aggregate demand is inadequate, the state should spend
more (and/or cut taxes). I.e. the state should “net spend”. The state can do
that (as pointed out by Keynes) either by spending borrowed money or by
spending freshly created money.
4.
Borrowing money when you can print the stuff is pointless. Only a lunatic would
do that. Ergo the government should simply print money and spend it (and/or cut
taxes) when AD is insufficient. Certainly Warren Mosler (leading MMTer) advocated that government should borrow
nothing, as did Milton Friedman in a 1948 paper. Personally I agree with them.
5.
Most so called “professional” economists are lunatics.
6.
The reason Keynes emphasised borrowing rather than printing money so as to fund
government spending was that he was a clever man who was surrounded by people
who, relatively speaking, were Neanderthals. That’s “Neanderthal” as in “go
ballistic whenever the words “print” and “money” appear in the same sentence”.
7.
Where the state creates new money and spends it, the effect comes via two
channels. First, the fact of spending (e.g. on roads, education or whatever)
employs more people (on repairing / building roads, in schools, etc). Second,
the increased stock of base money / PSNFA in private hands increases private
sector spending.
8.
If the state funds the extra spending via borrowing, the net effect per dollar
spent is significantly reduced, which is an additional reason for thinking that
borrowing money when you can print the stuff is a sign of lunacy.
9.
If the state prints and spends too much, the private sector will end up with an
excess stock of base money, and excess AD and excess inflation will ensue. The best cure for that is to cut down on the amount of money printing, or even reverse it: e.g. raise taxes and "unprint" the money collected. But an additional possible tool is for the state to borrow back some of that money. Borrowing (to repeat)
is pointless. Though in emergencies, that borrowing is probably justified so as
to damp down AD. However, the long term aim should be zero government
borrowing.
10.
One of the many defects in the latter borrowing is that the interest is funded
by ordinary taxpayers and ends up in the pockets of those with an excess stock
of money, the rich. And that’s a third reason for thinking that government
borrowing is lunacy (except as stated above as an emergency measure for damping
down AD).
11.
A state which issues its own money (e.g. the US, Japan, UK, etc) can pay any
rate of interest it likes on its debt. If the existing rate is a bit on the
high side, all such a state has to do is print money and buy back the debt (or
cease rolling it over). That equals QE. As to any excess stimulatory or
inflationary effect that has, that can be negated by increased taxes or reduced
government spending. However, the NET EFFECT on AD is zero (assuming the latter
“negating” effect exactly equals the stimulatory effect). Thus there needn’t be
any effect on numbers employed or GDP from the latter “interest reducing”
exercise (at least in the case of a closed economy).
In
the case of an OPEN economy, i.e. where some government debt is in the hands of
foreigners, the latter debt reduction exercise will obviously result in funds
being withdrawn from the country in question, which will reduce the value of
its currency on forex markets, which will hit living standards in the country
in question.
12.
The above is all way beyond the comprehension of most so called “professional”
economists, but it should be within the grasp of the average intelligent
fifteen year old. Certainly there isn't a cat in Hell’s chance of Rogoff or
Reinhart ever understanding the above.
13.
Forget all about “monetary policy”, “fiscal policy”, “fiscal consolidation”
etc. That’s all boll*cks.
14.
David Hume spelled out the REAL REASON for government borrowing over 200 years
go: as he pointed out, borrowing enables incumbent politicians to ingratiate
themselves with voters. That is (as pointed out above) cutting government debt
in an open economy involves a finite but temporary standard of living hit. Conversely, increased borrowing temporarily
increases living standards, and thus the number of votes that incumbent
politicians get.
