Michael Pettis — Thin Air’s money isn’t created out of thin air

A recurring conversation I have with clients concerns the ability of banks to create credit, and of governments to monetize debt, and whether this ability is the solution to or the cause of financial instability and economic crisis. Monetarists and structuralists (to use Michael Hudson’s names for the two sides, whose centuries-long debate pretty, exemplified by Thomas Malthus and David Ricardo during the Bullionist Controversy, dominates the history of economic thinking) have very different answers to that question, but I will suggest that each side disagrees because it implicitly assumes an idealized version of an economy.
We are normally taught that banks allocate credit by lending the money that savers have deposited in the banking system, but in fact banks create deposits in the banking system by creating credit, so it seems to many as if they can create demand out of nothing. Similarly, if governments are able to create money, and if they can borrow in their own currency, they can easily monetize debt, seemingly at no cost, by “printing” the money they need to repay the debt (actually by crediting bank accounts, which amounts to the same thing). This means that when they borrow, rather than repay by raising taxes in the future, all they have to do is monetize the debt by printing the money needed to repay the debt. It seems that governments too can create demand out of nothing, simply by deficit spending.
There is a rising consensus – correct, I think – that the misuse of these two processes – which together are, I think, what we mean by “endogenous money” – were at the heart of the debt surge that was mischaracterized as “the great Moderation”. For example in a book published earlier this month, Between Debt and the Devil, in which he provides a description of the rise of debt financing in the four decades before the 2008-09 crisis, along with the economic risks that this has created, Adair Turner specifies these two as fundamental to the rising role of finance in the global economy. He writes:
…in modern economics we have essentially two ways to produce permanent increases in nominal demand: either government fiat money creation or private credit money creation.
I am less than half-way through this very interesting book, so I am not sure how he addresses the main characteristics of debt, nor whether he is able to explain how much debt is excessive, or identify the main ways in which the liability side of the macroeconomic balance sheet intermediates behavior on the asset side to determine the growth and volatility of an economy. He invokes the work of Hyman Minsky often enough, however, to suggest that unlike traditional economists he fully recognizes the importance of debt.
And it is because of this importance that the tremendous confusion about what it means to create demand out of nothing is dangerous. When banks or governments create demand “out of this air”, either by creating bank loans, or by deficit spending, they are always doing one or some combination of two things, as I will show. In some easily specified cases they are simply transferring demand from one sector of the economy to themselves. In other equally easily specified cases they are creating demand for goods and services by simultaneously creating the production of those goods and services. They never simply create demand “out of thin air”, as many analysts seem to think, and doing so would violate the basic accounting identity that equates total savings in a closed system with total investment.…

The lack of separation between money and stuff in that post belies the assumptions underneath it. Economists seem to struggle with the idea that money is desired for its own sake.

And that everything is saved at any instant in time because by definition nothing in a snapshot is moving.

They have trouble in general with the time domain Neil... never were trained in it...

That's an insightful comment Matt. Consider that believing in Say's law (money neutrality) and that balance sheet asset prices being a mere non-reliable snapshot of valuations at a given time in a relative unit of measurement that itself can fluctuate relative to other units being the focus of many of the problems the world has today, and how pervasive and self-perpetuating those are into the economists mindsets.

Many economists fail to understand that the only constant in the universe is change, and man-made economies are not different. Is for this that any believe in 'equilibriums' is stupid. That doesn't exist in the real world, and a system left to it's own is subject to the effects of time, and by extension, entropy. Hence what we have right now in the world is increasing chaos and complexity... Too many economists in charge is creating this sort of trouble.

What on Earth is Michael Pettis wittering on about? If the state simply prints $100 bills, £10 notes etc and spends them, that creates demand out of nothing. Can’t see the problem with that idea.

Of course the spending may be excessive, in which case inflation kicks in. Or it may not be excessive.

NeilW said...

There's also the whopper that the balance of payments differential is *always* on the financial account. Yet domestically the financial account always sums to zero in toto (including government).

Because you have failed to separate 'real' savings from 'financial' savings in the financial circuit you can't tell the difference.

It's all a pretty serious case of premature abstraction.



Matt Franko said...

Ralph remember it is about price not quantity....

iow price which is measured at a moment in time is independent of some cumulative spending measure which is measured delta T , a sum over a period from t1 to t2 (delta t)...

iow if you look at price, it is measured as some currency unit per unit physical measure... like GPB/pint for your favorite... like Neil says delta T -> 0

so if you try to theorize that P = f(GBP)dt

iow if we posit that price is a function of GBP spending over some delta t, then the result will be price (P) as a cummulative GBP amount without a per unit of physical measure...

This is like saying that velocity is a function of distance delta t ... it is rather distance is a function of velocity delta t....

So if we are trying to determine how some total quantity of GBP spending can have an effect on price, then we have to come up with an equation where the right side of the = sign ends up in GBP/pint or GBP/tonne... not simply GBP...

This is like the commenter the other day who confused weight as a separate independent concept from force...

A title of ownership of a real asset is not a financial asset. A person owns a house and the title is the legal proof of that. A person owns a share of equity and the stock certificate is the proof of that regardless of where the legal title is held, under the mattress, in a safe deposit box, or in institutional account.

To count the legal proof of ownership as financial savings and the (share of) the real asset both in saving would be double counting.

When the value of the real asset appreciates or depreciates in the market the nominal value of the asset changes, but not necessarily the real value. Similarly, when a real asset appreciates through added investment or depreciates over time the real value increases or decreases and this may or may not be reflected proportionally in the nominal value.

If I grow a cucumber or cantaloupe, have a child or dig up a diamond for all intensive purposes, I've created something new of value for The King. In all societies with a western system of law, all property from the moment it is created is technically owned by the king/sovereign/government and they generously allow you to keep a portion of what you created for yourself. And The King keeps a portion for the rest of society. Our right to own land is no different from any other human creation in that sense. In the same way, you are granted control the land, so long as you pay tax (share production) and use it productively (follow King's law). Because certain areas of property law blur the line between real and financial, the functional reality of owning the property is no different than any other productive/creative act humans engage in. A loan, a stock, a bond, any financial claim is pretty hard to confuse with a piece of land or a cucumber or a baby. Common sense? Really?

The title to a house is proof of ownership, as a share of stock is proof of ownership of a portion of equity as ownership of a real good. The title or share is not a financial asset but the token of real ownership. If the token is counted separately from the real good, then there is double counting. That is a reason real assets are entered in the LHS and liabilities and equity on the RHS.

The nominal value of a real good can fluctuate in the market, e.g, a share of equity regardless of change in the real good, and changes in the value of a real good are not necessarily reflected proportionately in nominal value.

Real goods and legal ownership of them represented by RE title, stock certificates, etc. are categorically different from bonds and loans, which are financial assets that don't create comparable ownership claims on real goods. Confusing them or conflating then involves a category error.
