Imagined horrors: Additional notes on the Friedman interview

In a footnote in Breit and Ransom's The Academic Scribblers at Google Books, the authors quote from the “Has the New Economics Failed?” interview with Milton Friedman, and write:
In this interview, Friedman repeated one of his favorite propositions, "The best is often the enemy of the good," to point out that the use of both monetary and fiscal policy according to the well-intentioned precepts of functional finance has made the economy more erratic rather than smoother.
It's not simply fiscal policy Friedman is criticizing. He has a problem with any policy -- fiscal or monetary -- that attempts to "fine tune" the economy. In the interview he said
I’m not in favor of fine-tuning in that sense. I don’t believe we know enough to be able to do it. I don’t object to the aim; it would be very desirable to have an instrument that would enable us to keep the economy on an even keel. But I don’t think there is any. We do not know enough about either fiscal or monetary policy to enable us to make delicate adjustments from time to time that are going to offset other forces and make for greater stability in the economy.
Powerful stuff. With the interviewer's next question, focus returns to fiscal fine tuning: the tax cut of 1964. Friedman describes the performance of the economy before the tax cut became law:
There was a slowing off in the economy in late 1962 and early 1963, and there was a picking up of steam in the economy in late 1963 and early 1964— all of which happened prior to the tax cut.
"That steam kept on picking up at the same rate after the tax cut," he adds. This is where he says
some people will say that the economy moved ahead in late 1963 in anticipation of the tax cut. But then they also say that the actual occurrence of the tax cut fostered the growth afterwards.
And he dismisses that view as double-counting.

But then Friedman says:
If you want to explain the behavior of the economy during those periods, there is a much simpler explanation. In the middle of 1962 there was a sharp tapering off in monetary growth; some time in early 1963 there was a sharp speeding up of monetary growth. About six months after each of these, the economy showed the same movements. In a nutshell, the characteristic feature of this whole period, except for the 1962 interruption, was a steady rate of growth in the quantity of money.
In other words, the appropriate method of fine-tuning the economy is to keep "a steady rate of growth in the quantity of money."

So much for not knowing enough to make the delicate adjustments that offset other forces and increase the stability of the economy.


Premise: The use of fiscal policy (like the 1964 tax cut) to smooth the economy's performance is an unacceptable delicate adjustment.

I have to ask: How is it not also an unacceptable delicate adjustment to use monetary policy to smooth the economy's performance by maintaining a steady rate of growth in the quantity of money?

Observation: Friedman says neither fiscal nor monetary policy should engage in fine tuning, but he doesn't really mean it. He wants to fine-tune the growth of money so it is steady.

He doesn't want to turn tax policy "on and off like a faucet." But he definitely wants to step on the gas -- or the brake -- if money growth deviates from a straight and narrow path.


Two questions later the interviewer asks: "You would rely, then, entirely on monetary policy?" Friedman responds:
It depends on what you wish to rely on it for. I would not use monetary policy as it was used in the 1920s in any futile effort to fine-tune the economy. I bring out this comparison because at that time they were trying to do with monetary policy exactly what the New Economists are now trying to do with fiscal policy. To say that it didn’t work is to understate the case.
By understating the case Friedman appears to mean forgetting to mention that monetary policy in the 1920s created the Great Depression. But Friedman understates his case.

The best zingers are understated, no?

What really bothers me here is that Friedman says in the 1920s "they were trying to do with monetary policy exactly what the New Economists are now trying to do with fiscal policy." But he's offers no specifics. Friedman reminds us that the monetary policy of the 1920s created an economic disaster, then says fiscal policy of the 1960s is doing "exactly" the same.

It's innuendo. Friedman is not specific. We are left to fill in the blanks for ourselves, like a Hitchcock movie. And the human mind is very good at filling-in those blanks with imagined horrors.

Me, I don't know much about what else Friedman might have meant. So I turned to The Federal Reserve in the 1920s at New World Economics, which shows this graph:

Graph #1
And from that same page:
... by the early 1920s, the Fed had already gotten into the habit of being involved in the lending market on a day-to-day basis. During WWI, the Fed had been pressured by the Treasury to keep a lid on short-term and long-term interest rates to allow the Federal government to more easily finance its big wartime deficits. This of course required daily action. The Treasury stopped telling the Fed what to do after the war, but by then the Fed had become accustomed to being regularly involved. Bureaucratic expansion itself would have prevented any migration to the kind of largely dormant institution as the Fed was originally envisioned.
That's the context. Here's the policy the Fed pursued:
The Fed’s discount rate was kept at a level that made the Fed competitive with other potential lenders in the market. This was actually quite similar to the regular operating conditions of the Bank of England at the time. The Bank of England was also a private profit-making commercial bank, and thus made loans regularly. The Bank of England was not at all a dormant institution that only leapt into action during a once-a-decade crises. The Bank of England thus also had to keep its discount rate in line with other banks’ lending rates to stay competitive. In practice, the amount of actual loans made by the Fed or Bank of England was somewhat up to the discretion of the bank managers. If their rates were competitive and there was regular demand for borrowing, the Fed or the BoE could decide how much it actually wanted to lend.
In those early days, the Fed relied on the discount rate rather than the federal funds rate. They kept the discount rate "competitive": They let it vary with the rates of "other potential lenders". From the graph, this evaluation of early Fed policy appears correct.

So the Fed kept the discount rate competitive, and Friedman calls this a "futile effort to fine-tune the economy."


I could easily be wrong, and Friedman right. I know he studied this a lot more than I have. But here's the thing: He's only stating overviews. He provides no evidence. No examples. Nothing to let me understand why he says what he says. And when I go looking to see for myself, I don't see what I would see if Friedman was right.


After Friedman's understated zinger about understating the case, the next interview question is this:
You would merely expand the money supply by a certain rate and not concern yourself about the discount rate, open market operations or the other monetary powers of the Federal Reserve?
Friedman's response:
Not exactly. While I am opposed to using these weapons to fine-tune, under our present financial institutions having the quantity of money increase at a steady rate requires a great deal of intervention and action by the Federal Reserve. As it happens, I’m in favor of much more fundamental changes in our financial institutions. But under our present institutions, we can only get a steady rate of increase in the money supply if the Federal Reserve takes that as its objective and works on it. At certain times it would have to buy government bonds on the open market, at other times it would have to sell. It would also have to keep its discount rate in line with market rates, and so on.

I think that a misleading impression is given unless I add one thing: I’m in favor of a stable fiscal policy too. My view is that the problem with our fiscal and monetary policies is that the objective has been to offset other forces and thus insure stability. The actual result has been to introduce new instabilities. There’s the old saying—I’ve forgotten to whom it is attributed—that the best is often the enemy of the good. That is the case here. The attempt to use both monetary and fiscal policy for delicate adjustments in the economy has made the economy more erratic rather than smoother.
Again: Friedman objects to the idea of trying to "offset other forces and thus insure stability" because the "attempt to use both monetary and fiscal policy for delicate adjustments in the economy has made the economy more erratic rather than smoother."

He's comfortable with the idea that if you do nothing you don't introduce instability. And yet, he doesn't want to see money growth slow down as it did in the middle of 1962. He wants to prevent the erratic growth of money.

The other guys talk of fine-tuning the growth of the economy; Friedman's idea is to fine-tune the growth of money. But he pretends the other guys are fine tuning and he is not.

Friedman is interfering, the same as the other guys. But he pretends he is not.


Let's go back to that "stability" thing:
  • The zinger is about policy creating the Great Depression. That's not stability.
  • The whole interview is about policy trying to attain "greater stability in the economy."
It seems that by "stability" we mean minimizing recessions and eliminating depressions.

Here's a picture showing the duration and frequency of recessions since 1854:

Graph #2
The left half of the picture is mostly gray; the right half is mostly white.

The left half is mostly recession; the right half is mostly growth.

The dividing line appears to occur at the end of the Great Depression (March 1933). If recession is the measure of economic instability, our economy has been noticeably more stable since the end of the Great Depression.


I'll re-quote from "The Kennedy Tax Cut of 1964":
The economists in the Kennedy administration observed that there had been three recessions in the two Eisenhower administrations (1952–1960): one from 1953 to 1954 after the Korean War, one from 1957 to 1958, and one in 1960.
And from Time magazine of December 31, 1965:
They began to use Keynes's theories as a basis not only for correcting the 1960 recession, which prematurely arrived only two years after the 1957-58 recession, but also to spur an expanding economy to still faster growth.
There were three recessions in Eisenhower's eight years, the last of them in 1960 as Kennedy came into office. These recessions were fresh in the minds of Kennedy's Council of Economic Advisors, and they set to work shortening that 1960 recession.

And there wasn't another recession until 1969. A long stretch. You can see it on Graph #2: the three close recessions of the Eisenhower years, followed by a clear span till 1969. So it looks like the "fine tuning" of the 1960s had the desired effect. (Along with some side effects, perhaps, like rising inflation.) But if the measure of economic instability is recession, then there is evidence that economic stability has increased.


And after ruminatin, I can't really see that Friedman "has a problem with any policy -- fiscal or monetary -- that attempts to 'fine tune' the economy." I can see that he says he has a problem with it. But I don't see it in the other things he says.

I don't think Friedman is saying that his proposal is not fine tuning. He even said that fine-tuning the economy is a good idea if it were possible, but he claims it is not possible and it always ends up with the unintended result of less growth.
His point is that fine-tuning the money supply so that it grows at steady rate in proportion to potential productive growth is simpler and if that's done the economy will respond by fulfilling its potential.

Friedman (and others) made this argument convincingly enough that Congress enacted it into law in 1978:


********************************************
Section 2A. Monetary policy objectives

The Board of Governors of the Federal Reserve System and the Federal Open Market Committee shall maintain long run growth of the monetary and credit aggregates commensurate with the economy's long run potential to increase production
*************************************************

In a 2006 interview:
Milton Friedman: I’ve always been in favor of abolishing the Federal Reserve and substituting a machine program that would keep the quantity of money going up at a steady rate.

Russ Roberts: And over the last 20 years or so, they’ve approximated that.

Milton Friedman: Come closer to approximating it. Absolutely.

Russ Roberts: And I would argue, and I assume you would as well, that the relative stability of the U.S. economy over the last 20 years is a reflection of that steady growth in the money supply.

Milton Friedman: I think there’s no doubt at all.

The Arthurian said...

Hey Jim.
"I don't think Friedman is saying that his proposal is not fine tuning."

Well, he says he opposes fine tuning. Then he goes ahead and recommends stable money growth, something that looks like fine tuning to me and evidently to you, too.

I know he says he's "in favor of much more fundamental changes in our financial institutions." But as that seems a bit out of reach, I guess, he opts for stable money growth. But he doesn't quite admit that he is opting for fine tuning, far as I can see.

Maybe it was edited out of the interview.

Too bad Friedman didn't live a couple years beyond 2006. He would have seen sudden instability interrupt the relative stability that was a reflection of the steady growth in the money supply.

He isn't against fine tuning in general and would even support this particular form of fine tuning if it worked, but he says, it doesn't work.


There is a good argument that the great recession was much bigger contraction of the money supply then the great depression. Many trillions of dollars of "money good" assets that firms held on their books as "cash balances" suddenly became no longer accepted by the markets for payments.

the great depression saw a 25% reduction in the money supply over 4 years. The great recession saw that happen in a several weeks.



The Arthurian said...

Friedman: "I’m not in favor of fine-tuning in that sense."
Jim: "He isn't against fine tuning in general ..."

Yeah. Well said.

"There is a good argument that the great recession was much bigger contraction of the money supply then the great depression... the great depression saw a 25% reduction in the money supply over 4 years. The great recession saw that happen in a several weeks."

So, an argument for stable money growth? Okay. But that contraction of the money wasn't the Fed taking all this money out of the economy. It was "the markets for payments" that lost confidence and decided not to accept those "money good" assets.

The 20 years of steady growth in the money supply, noted by Russ Roberts, did not prevent the collapse in the quantity of money.

It was the bank and shadow bank money that collapsed, not the government issue.

It was private money growing faster than government money that made the collapse possible, made it likely, and made it happen.

The Arthurian said...

And the monetary policy solution for the crisis & great recession, Quantitative Easing, corrected the imbalance between private and government money by increasing the latter.

It would have been so much better to reduce the former.

jim said...

Easing, corrected the imbalance between private and government money by increasing the latter.
It would have been so much better to reduce the former.
**********************

It was the former that was reduced and the reduction was rather large and abrupt.

But your missing a crucial point that the reduction revealed - it is not the Fed or the govt that decides what is money. It is the private markets that make that determination.

Consider this: For the last 10 years Fed Wire money transfers have averaged around $3 trillion per day. From 2009 to 2012 the daily average dropped by about 1/2 trillion per day, but its back up to a little higher than it was before the crash.
That $3 trillion per day doesn't include currency that changes hands daily and it doesn't include many local transfers of money (think retail shoppers). What this means is that the amount of money that was changing hands daily in the US economy was at least 3 times as large as
M1 money supply, in 2008.

Does anybody really believe the entire M1 money supply was changing hands every couple of business hours?

And yet you have economists like Friedman talking about the quantity of money without giving a hint that they understand what that quantity might actually be (measured accurately) or what determines its magnitude at any given point in time.

So how big is the supply of money that is being used daily for transactions? Is there anybody even trying to keep track?

The Arthurian said...

Hey.
"It was the former that was reduced and the reduction was rather large and abrupt."

Additions to debt were largely and abruptly reduced. Extant debt lingered, and lingers still. "Additions to debt" is, you know, borrowing and using credit for money.

Private-issue money is credit. Government-issue money is money. The ratio of the one to the other is the crucial thing. It is the most important ignored thing in all of economics.

I don't think I miss the point that private markets decide what is money. But private markets are fickle, and their definition of money changes as soon as they smell a profit or a loss. Those changes are a source of trouble and instability for the economy. (That's what Minsky was talking about.)

"the amount of money that was changing hands daily in the US economy was at least 3 times as large as
M1 money supply, in 2008."

First off, intuitively, and without question, this is a problem. All, or nearly all of that money changing hands daily, was for nonproductive financial activity: Skimming profits from the productive sector.

The financial sector is now so much larger than the productive sector that we seem to have reached the upper limit of what is possible. Ergo Trump.

*********************************

The reduction in debt growth was mostly due to existing debt not lingering. Here is a graph of the outstanding mortgage debt that was financed by private investors thru non-govt backed mortgage conduits:
https://fred.stlouisfed.org/graph/fredgraph.png?g=mlN9

That market funded about 40 million mortgages that were supposed to be 30 year loans. Does it look like that debt lingered?

That's true but tell that to the monetarist followers of Friedman. They and Friedman claim the opposite is true.

I agree with the first sentence but am mystified by the "ergo" in the second. I think voters could be placed in one of three categories. Those who think Trump is working for the financial sector, those who think he is working against it and those who think the financial sector is irrelevant(most of those voters think immigrants are the big problem)

"The reduction in debt growth was mostly due to existing debt not lingering. Here is a graph..."

Jim, I'm not familiar with the several "Mortgage Debt Outstanding by Type of Holder" data series. I will tell you what I'm thinking. Tell me if I have something wrong.

That's an impressive peak on the graph you show!

I looked up the data series you used. The page links to "Mortgage Debt Outstanding, All holders". This one shows TOTAL mortgage debt, I'm thinking.

"Private Mortgage Conduits", the one you show, peaked at about 21.5% of total mortgage debt in 2007 and has since fallen to about 5.6%.
https://fred.stlouisfed.org/graph/?g=mmnM

The data you show definitely fell, and fell faster than total mortgage debt outstanding. But this means that total mortgage debt fell much less than you suggest.

Total mortgage debt outstanding peaked in Q2 2008 at 14.8 million million (14.8 trillion). It reached a bottom in Q2 2013 at 13.3 million million, and is now higher than it was at the previous peak.

The "Private Mortgage Conduits" debt peaked in Q3 2007 at 3 million million. In Q2 2013 it was down to 1.3 million million. Since Q1 2017 it has been holding in the neighborhood of 0.85 million million.

Total mortgage debt outstanding, in Q2 2013, had fallen to just about 90% of its peak value. By that date, Private Mortgage Conduits debt had dropped to less than 45% of peak.

The debt you show fell rapidly. But Total mortgage debt fell neither rapidly nor far. This may have been due in part to panic-induced accelerated repayment. But I think it was due mostly to banks making fewer mortgage loans, and/or borrowers not wanting to borrow. Thus I say that additions to debt were largely and abruptly reduced, while extant debt lingered.

I note, also, that mortgage debt is not all the debt that there is.

Total mortgage debt outstanding, since late 2006, has fallen as a share of "Total Credit to Private Non-Financial Sector", from 61% in late 2006 to less than 51% now.
https://fred.stlouisfed.org/graph/?g=mmnN

This means that private debt has been growing faster than total mortgage debt.

Finally, "Total Credit to Private Non-Financial Sector" fell from Q4 2006 to Q1 2013 as a percent of "All Sectors" (TCMDO) debt. This means that "All Sectors" debt has been growing faster (or shrinking more slowly) than private non-financial debt.
https://fred.stlouisfed.org/graph/?g=mmo0

//

To summarize:

Total mortgage debt has been growing faster than the private mortgage conduit debt that you show.

Private Non-Financial debt has been growing faster than Total mortgage debt.

And All Sectors debt has been growing faster than Private Non-Financial debt.

These statements are true since around 2006 and continuing thru to around 2013 (and beyond).

Therefore I think it is incorrect to say "The reduction in debt growth was mostly due to existing debt not lingering."

My conclusion remains the same: Additions to debt were largely and abruptly reduced. Extant debt lingered, and lingers still.

**************************

the way i look at it that statement is false.
It just looks like new additions to debt stopped, but what actually happened was old debts being repaid at an accelerated rate more than offset the growth of new debt.

However, the data you looked at doesn't reveal the full extent of the accelerated destruction of debt. As you noted there is less than $1 trillion of the privately funded debt left. The total amount of mortgages funded by nob-bank and non-govt backed private channels was more than $6 trillion. In other words, there was more than $5 trillion that did not linger. A considerable amount of the debt was already repaid while the outstanding debt was still growing. Had these 30 yr mortgages been lingering the graph would have gone twice as high as it did.

But there is much more debt that also did not linger...
You excluded the financial sector's debt. If you include finance you would see that the decrease in existing debt was even greater than private non-financial.

The reason I brought up the fedwire money. Is because that reveals that there is a lot more "spending money" than we are told. And yes that may well be mostly non-productive debt money sloshing around in the financial sector, but I see good reason to not ignore it, because when that elephant in the room sneezes the rest of the economy catches cold.

The Arthurian said...

Dunno, Jim. I remember all that talk in 2008 and after, about how banks were unwilling to lend. And then the discussion became a question: Is it that banks are unwilling to lend, or that people are unwilling to borrow?

You seem to be telling me that this general discussion was all wrong.

As I recall, people's preference changed from borrowing more to repaying more. So then it's not only that the additions to debt slowed, but also that the repayment of old debt accelerated. But you can only pay off as much as you can afford to pay off. Seems to me most people didn't have the money to pay down debt as rapidly as you seem to be saying. People with money, yeah. But the rest of us? I don't see it.

Hey, I got a mortgage in August of '08, and so did the guy who bought my old house. My experience contradicts the general discussion of the time. But my experience only puts two data points on a graph. Whether they are two among many, or two among few, my experience cannot say.

I did look at "repayment of principal" a couple years back, for household debt.
http://newarthurianeconomics.blogspot.com/2016/07/debt-service.html
Taking Graph #4 ("The Principal Repayment Portion of Household Debt Service, in Billions") I'll add Household Debt as a second line... and show both lines as "percent change from year ago".
https://fred.stlouisfed.org/graph/?g=mod6

• From 2006 to the start of the Great Recession, principal repayment growth spiked upward while debt growth fell.
• During the Great Recession, the two fell together.
• In 2009 debt growth resumed slow growth. That slow growth continues to end-of-data.
• In 2011 repayment of principal shot up to the 5% level, and has stayed near that level since.

As it looks to me:
In 2006-2008 people were definitely paying down debt faster. Can't say if they were borrowing less because repayment affects the numbers.
During the Great Recession, people couldn't afford rapid repayment, and didn't borrow.
In 2011 repayment became faster again -- because people could better afford it, after the recession.
However, we apparently can't afford a lot of repayment, so repayment growth topped out at 5%.

This is only household debt & household debt repayment.
