Contrary
to conventional wisdom, central bankers don't have have the tools required to
maintain price stability. Neither do governments. This is not to say that their
actions don't affect inflation. When we combine the tools the central bank has
(mainly the target rate) with the tools government has (mainly its control over the budget
deficit/surplus), we are able to create inflation or deflation, depending on
which one we want.
The
ability to create inflation doesn't translate to ability to maintain price
stability. The problem is that even though we can create inflation at will, we
have no idea how much of it we will get -- and even more importantly, what will
be the rate of change in inflation (for geeks: this is the second derivative of the hypothetical, general price level) at any point in
time. Two years after the start of a government intervention, inflation
could be three percent or it could be 10 percent, and it could be accelerating
or decelerating. The most technically-minded among us might try to convince you
otherwise, but they ignore the importance of inflation expectations and the
role psychology plays in forming these.
The appearance -- or even a threat thereof -- of large fiscal deficits would affect inflation expectations among the public (investors included) in a very unpredictable way. As a consequence, inflation itself would be unpredictable (to be clear, time-lags, too, would make inflation management very difficult). This is because inflation expectations -- which depend heavily on human psychology and the relative attractiveness of competing stories -- are what really drives current and future inflation. All this is related to reflexivity.*

The
"natural" (this is, absent a large-scale government intervention)
outcome of our current debt overhang would be debt deflation. As far as I know, this is what William White is alluding
to when he says "They have created so much debt
that they may have turned a good deflation into a bad deflation after
all.".
As
I suggest above, and as Milton Friedman among others has suggested before me, a
deflationary spiral could be countered through very large fiscal deficits
(~10-20 %, without pretence to accuracy). This deficit could be
"sterilized" (I stretch this concept) through a) new issuance of
government bonds (by Treasury), or b) sale of existing ones (by central bank),
or it could be un-sterilized as in "helicopter money" (see, for
instance, Simon Wren-Lewis here) or overt money financing (OMF). (Related to this, I'd
like to hear from Wren-Lewis, or any other expert, what is the difference
between financing the deficit, on one hand, through bond issuance, and via OMF on
the other, in a world where 2-5-year bond yields are negative while cash yields
zero?)
So,
my mental framework (or, theory) suggests that through large fiscal deficits an
impending, severe debt deflation can be turned into volatile and unpredictable
inflation. This inflation, or expectations thereof, would initially bring us
increased spending, increased output and employment. It would increase the real
GDP. This is exactly what the most short-sighted of us are after when they call
for substantial government spending financed by a large fiscal deficit (this is
why the "austerity vs. stimulus" debate doesn't make much sense to
me). But this boost to the economy would be, to a large extent, due to
increased speculation. At the extreme, we would see a Black Friday-esque
spending frenzy as perfectly rational agents rush to buy real assets with
existing and newly-created IOUs (formerly known as "money"), as they
expect the value of currency to greatly diminish in the future.
All this should be clear to any attentive student of inflation. Almost as clear
to me is that we have already seen this kind of speculation in 2009-2014, albeit on a very small
scale relative to potential.
Eventually,
after a period of accelerating inflation, we would need to do what Paul Volcker
and the Fed did -- thanks to sufficient public, and thus political, backing --
in the early 1980s. We would need to bring inflation down through an
instant, deep recession and mass unemployment. Of course, there's always
another option: to let the inflation run its course. I think we widely agree
that it's better to take the recession than go down this path. Still, we cannot
fully count on this to remain the case if push comes to shove.
There's
always a possibility that the fiscal deficit would not be large enough -- let's
say, due to political resistance -- to get the inflation even at the target
level. In my world, this deflation or "low-flation" would ultimately
have its cause in authorities' inability to convince agents that they should
spend before inflation arrives and starts eroding the purchasing power of the
currency. Something like this has been going on in Japan for something like two
decades. But as my critique is aimed mostly at the same people who insist that
Japan has not yet tried hard enough, and that all would be better there had
they just tried harder, I won't analyze this possibility in detail here. All I
want to say is that if we try hard enough, at one point we will get the volatile
inflation and the (new) problems that come with it.
I
state my critique once more: Inflation is not micromanageable in the way Modern Monetary Theorists (MMTers) or the living advocates of The Chicago Plan (CPs) seem to
suggest. And I'm willing to bet that many of our best investors agree with me. We should never underestimate the effect of
speculation on economic outcomes. Neither should we underestimate the
difficulties we face if we try to differentiate between speculative and non-speculative
transactions.
The
biggest reason why we ended up with this massive, global debt problem is our
inability to understand how all "money" is just a promise to pay (an
IOU), and, as it logically follows, that it is not possible to pay for anything
with this "money" (see my post from yesterday). Once we accept this, we
must accept that the Quantity Theory of Money (QTM) should be
dismissed in its entirety. But this we haven't done. Even people who understand quite well
how "money" is just an IOU (for instance, MMTers and CPs) still view
inflation more like a technical issue, something that is micromanageable --
wait for it -- through well-calibrated injections and withdrawals of
"money" by the government. Are they all monetarists now?
I'm puzzled. Sometimes I wonder if nearly all our economists are suffering from doublethink.

I'm greatly indebted to George Soros who, with his book "The Alchemy of Finance" (1987), has
shed much light on reflexivity both in financial markets and the economy in
general. Robert Shiller has helped me better understand the role stories have
in affecting outcomes (see, for instance, his article at Project Syndicate). I present
Soros as the prime evidence for my claim that to understand the economy one
needs to be a philosopher, while Shiller's work speaks for the importance of
understanding psychology. The society consists of individuals who contemplate
and participate (i.e. act); they both compete and co-operate. That's probably
all there is to an economy.
Mumblings post scriptum
There
are many ways out of our current mess. Some are much better than others. None
of them is an easy one. We have only bad options left. On the normative side,
once we get there, I have a lot of suggestions on how to ease the pain, how to
take care of the society and build a better future for all of us. (I'm dismal
only as a scientist, not as a human being.) But first, we need to agree on what
is ailing us -- only then we can try to apply the right treatment.
What got us here is our mistaken belief in the existence, both on a microeconomic and a macroeconomic level, of "money". The truth is that our financial system consists only of debts and credits -- all kinds of liabilities and a mountain of IOUs. The current amount of these liabilities and the corresponding IOUs is just too big. This is what is ailing us. We need to get it back to a substantially lower level, and it seems to me that it will take a global recession ("It" will happen again) to achieve this. This is my diagnosis (it's based on a considerable amount of work I've done since 2008). As we analyze the treatment options and weigh them against each other, we should keep in mind the following goal: to get the world through this turmoil with the least possible damage.
