Brad DeLong and Charlie Deist on Austrian Economics

Charlie Deist: Brad DeLong on Austrian Economics:

Charlie Deist: Good morning everyone, and welcome to the Bob Zadek Show.

I’m Charlie Deist, Bob’s producer, once again filling in for Bob, who will be back next week to discuss the topic of morality and capitalism. Are the two compatible? Is a moral citizenry required for a capitalist system, or is it the inverse? Is capitalism the only system that does not require a moral citizenry?

I also want to wish our listeners a “seasonally-adjusted greetings.” The adjustment is both my filling in, and my special series here on the business cycle. When we talk about economics, we often refer to seasonally-adjusted statistics—business cycles fluctuate up and down, not only in these longer boom and bust cycles, but also throughout the year. Around Christmas time, consumers are running off to the store to buy the latest gadgets and gizmos, so we see a temporary spike in spending.

Last week I was joined by Robert Wenzel, who is a self-described Austrian economist. That does not mean that he is of Austrian nationality—it means he follows the ideas of libertarian economists such as Friedrich Hayek, and Ludwig von Mises. These were 20th-century economists who built a foundation for economics on a philosophical concept that is both simple and profound—that is, that humans are purposeful actors; we act with an intention to achieve certain aims, and use economic means as well as other means to achieve our desired ends.

The Austrian school is important today because everyday we see stories on the front pages of the newspapers about booms and busts, bubbles bursting, Bitcoin, etc. Is Bitcoin a bubble? We might wonder whether humans are actually rational. Are they pursuing their ends in a way that will actually best achieve them, or are they, perhaps, less than perfectly rational?

These are the kinds of questions that economists debate, and today I’m privileged to have an economist with me. I’m joined this morning by UC Berkeley economics professor, Brad DeLong. Every so often, I need to ask a favor of Brad DeLong. He’s my old teacher and undergraduate advisor, from when I was something of an aspiring libertarian economist.

While preparing for last Sunday’s show, on the hardcore libertarian Austrian theory of the business cycle, it occurred to me that I don’t actually know what I’m talking about. I don’t have a PhD, or even a Master’s degree in economics, although thanks to Brad I was able to complete an undergraduate thesis on monetary policy. But it occurred to me, if I were in almost any other field, trying to diagnose a problem—something as complex and serious as the booms and busts in the economy, my musings here would be something akin to malpractice.

Brad DeLong is the chair of the political economy major at UC Berkeley. He was deputy assistant secretary at the U.S. Treasury, and is a visiting scholar at the San Francisco Federal Reserve Bank. He joins me by phone from Berkeley, where he also writes the popular blog, “Grasping Reality with Both Hands.” Now, that’s a metaphor, so if you’re driving keep both hands on the wheel.

I’m going to try to cram in close to a whole semester of economics with Professor DeLong, and hopefully he can help to explain in layman’s terms, his academic perspective on what’s really going on in the economy when we read about the Federal Reserve and interest rates, money supply, quantitative easing, and so on. Thanks for taking the time to talk with me.

Brad DeLong: It’s a great pleasure on my part to be virtually here. Thank you for asking me.

Charlie Deist: I want to start with a quote from a blog post that you wrote all the way back in 2004. This was when Alan Greenspan was still Federal Reserve Chairman, and it echos the message of my last guest, which was that the Federal Reserve negatively influence the economy—I don’t think there’s any question about that among economists. This was the end of a post from April 2004, where you were trying to figure out what was going on with monetary policy at the time.

You said:

Alan Greenspan frightened away the evil depression fairy in 2000 to 2002, by promising—not that he would let the evil fairy marry his daughter—but by promising high asset prices, unsustainably high asset prices for a while. Whether this was a good trade or not depends on the relative values of the risks avoided and the risks accepted. And to evaluate this requires a model of some sort…

So back in 2007, you were worried, just like our last guest, about the Federal Reserve inflating a bubble. What would you say is the Keynesian perspective, if you will, on the potential for the Federal Reserve to engage in this kind of pro-cyclical monetary policy—i.e., monetary policy that, rather than smoothing out the business cycles like it’s supposed to, actually can exacerbate them and make them worse?

Brad DeLong: Well, I would say that it’s not so much a Keynesian perspective as a Keynesian–Monetarist perspective. Or rather, since Keynesianism, Monetarism, and Austrianism are all very large and vague, unsettled creatures with very fuzzy borders, such that it’s not clear where the core is, let’s say John Maynard Keynes himself rather than the Keynesians, Milton Friedman himself rather than the monetarists, and Friedrich Von Hayek himself rather than the Austrians.

Here Keynes and Friedman would have been on the same side, approving of Greenspan’s policies. That is, Keynes thought the most important thing for monetary policy was to manipulate the economy so that the level of spending in the economy—the level at which the government plus private actors wanted to spend—was large enough to be able to put everyone to work, who wanted to work, at the prevailing wage level, without creating an excess of demand, over the amount that could be produced that would produce inflation. That, as he said, inflation is unjust in that it robs the saver of the returns that they’re expecting, and deflation is inexpedient. Perhaps deflation is worse in an impoverished world, but these are both evils to be shunned.

Milton Friedman was very much the same. That is, Milton Friedman thought that the right policy for the Federal Reserve to follow was for it to be constantly intervening in asset markets in order to keep the money supply from falling—even if private actors wanted to shrink their holdings of money—or keep the money supply from rising if private investors and private actors wanted to increase the supply of money. Also, Friedman thought that if there were to ever be sharp shifts in the velocity of money—sharp changes in how much people wanted to hold in terms of dollars in their bank account for every dollar they spent—the Federal Reserve should offset those too.

So in both Friedman and Keynes’ view, the right strategy for the Federal Reserve was the Greenspan strategy of “act to try to keep inflation and unemployment as stable as possible, by doing whatever is necessary in terms of buying and selling assets, and pushing asset prices up and down.” It’s just that Friedman called it a neutral monetary policy, and Keynes feared that the Federal Reserve would not be able to do enough, and that you’d have to bring in other tools as well.

I think Keynes has won this one after 2007 to 2009, when the Federal Reserve did everything and it didn’t work. But they’re on one side agreeing with Greenspan.

Hayek, and I suppose also Hyman Minsky—who are on the other side—were saying back in the 1930s, the 1950s, the 1960s, that no, this is a very dangerous policy to pursue.

Charlie Deist: So there’s a lot to unpack here. We have four names: Keynes, Friedman, Hayek and now Minsky, who we’ll try to get to later. And each of them is telling a different story, and proposing a different remedy for this problem of the business cycle.

You used the word “manipulation”, and that seems to be where the Austrians would have the biggest disagreement with even the monetarists like Milton Friedman, who was one of the most famous libertarians—maybe the most famous libertarian. Yet, in this one area, Friedman did favor a role for government manipulation: of the money supply. This gets to the core of the technical debate in monetary policy, which is, what is the Fed actually doing on a day to day basis? How do they adjust, both through direct action and through the influence of expectations of the actors in the economy? Let’s summarize for listeners in layman’s terms how they influence the economy. Economists talk about a transmission mechanism. This is just the direction of causality from one action to the results that we see. Could you break down how the Federal Reserve actually achieves the smoothing of the business cycle, in either the Keynesian model, the Monetarist model, or whichever hybrid of the two you think makes the most sense?

Brad DeLong: Well, as early liberal John Stuart Mill put it back in 1829—and I think he got it right and Keynes and Friedman would agree—that the economy is in balance, in a business cycle sense, if the supply and demand for money are equal. That is, if demand for money is greater than supply, then people are cutting back on their purchases because they want to hold more money than they can find. Then you have what they used to call in the colorful language of the early 19th century call a “general glut of commodities”: high unemployment, idle factories, cotton goods going begging as far as Kamchatka, in Thomas Malthus’ phrase. That’s a bad thing. And if the supply of money is greater than the demand, well that’s inflation, which is also a bad thing.

To keep the economy in balance, you need to match the supply and demand for money. But since the demand for money is somewhat erratic, the Federal Reserve or the Bank of England always have to be in there, buying and selling, pushing and shoving, increasing and decreasing the supply of money in order to keep there from being either unwanted inflation or unwanted deflation. That is just the way things are, if you are going to keep the economy stable.

Now this is a somewhat awkward position for Milton Friedman to be in because when you ask Uncle Milton about practically any other market, his response is, “The market will sort it out optimally. And even if the market wouldn’t sort it out optimally, building up any government bureaucracy to try to do better is doomed to failure.” Yet somehow, with respect to monetary policy, Uncle Milton goes very far towards saying that there are major institutional or cognitive human deficits in how the market for money works. So, we have to have this form of extremely soft, light-fingered central planning for the money supply—which he hoped could be done by a rule. That the Federal Reserve is going to say, “We’re going to let the money supply increase by one percent every quarter.” But it turned out that such rules don’t work very well. We need much more complicated rules—we need feedback rules, and even with the feedback rules, we have to deviate from them substantially on occasion.

So that is very much what Friedman and Keynes think is going on there. Minsky thinks that’s going on too, but Minsky also thinks that the same current of thought and institutions that lead to episodes of deflation and inflation in the private market—to financial over-speculation and so forth—that those are also going to affect the minds of policy makers. So, it’s just when asset prices are rising and people are enthusiastic and getting over-leveraged, then you’re going to find large political calls for deregulation of finance and for a reduction in regulatory requirements for collateral and down payments. And, conversely, just when the economy is in serious trouble and people are depressed, that’s when you’re going to have the Dodd-Frank bills imposed. That’s when you’re going to have governments demanding lot higher down payments. That’s when you’re going to have collateral requirements required by the Bank of International Settlements go through the roof.

Charlie Deist: So Minsky tells another story of the pro-cyclical policy where government, rather than smoothing out the business cycles, is tracking with either the people’s confidence of lack of confidence in the financial system. It’s a case where human irrationality and the lack of a sound technician at the board, so to speak, is leading to these wild fluctuations.

Brad DeLong: Well in Minsky’s view it’s a logical impossibility. Right? That, as William McChesney Martin—Fed Chair in the 1960s—said, “The purpose of the Federal Reserve is to take the punchbowl away just when the party gets going.” But just as the party gets going, that’s when absolutely nobody wants to take away the punch bowl.

Basically, Minsky had all kinds of hopes about how—because we would understand this cycle—we could transcend it, and moderate it, and deal with it. But those are basically unconvincing. If you take a Minsky point of view, we’re pretty much hosed, and all we can do is remember the historical parallels and analogies, and whimper and complain whenever this cycle gets going.

Charlie Deist: Tell us Hayek’s story—how Hayek relates to Minsky, and how it might echo it in some ways, or vice versa.

Brad DeLong: With Hayek, it’s in some sense very apocalyptic. It’s that everything would be fine if the market were just working well. It’s that you do not have a sudden large increase in the demand for money—the kind of thing that produces a depression—unless you had a large previous episode in which too much money has been created; in which the economy has somehow found itself with lots of liquid assets, which do not correspond to any fundamental values, either because the government has previously been printing a lot of money and generates an episode of inflation, or because the banking system has gone absolutely haywire, and private agents are facing bad incentives. Banks have extended many, many, too many loans thinking that they’ll reap fortunes if there are no bankruptcies for as long as they’re president of Bank of X. And if there should be bankruptcies, well, they’ll probably have moved on to another job by now.

So it’s a combination of fecklessness on the part of politicians who print extra money to spend or to lower taxes and so produce inflation, plus a principle–agent failure in the banking system, in which bankers make loans that are really lousy business in the long run because, hey—the long run might not come until they’ve moved on to another job.

That creates the inflation, and only after the inflationary boom comes is there ever a chance of being a large recessionary crash. So, for Hayek it becomes somewhat of a moral answer: that you have to keep the government a kind of moral, budget-balancing government, and you have to keep the bankers from grabbing us by the plums. And if we can have moral bankers and a moral government, somehow, then everything will be fine.

Charlie Deist: That’s an interesting interpretation—I want to pause on this question of market failure versus government failure. It’s a mixed story that you’re telling, where on the one hand there are the politicians and their short-sightedness—their money printing. On the other hand, there’s what economists call a “market failure,” which is where private actors supposedly acting in their own best interest, either short-term or long-term, make loans that will not bear the fruit necessary to pay back those loans.

So we end up with people, not only borrowing, but leveraging or borrowing with the money that they’re making initially off asset price increases.

They inflate this bubble, and get overly optimistic about the proceeds from this investment initially, so they’re doubling up, until we reach what’s called the “Minsky moment,” where everyone suddenly looks around and realizes that the punch bowl has been taken away, or that these investments are clearly not sound. And then we get a sudden crash.
Hayek said that this would not happen if government was not inflating a bubble, but Minsky considered himself a Keynesian, I believe, and argued that this would happen in the absence of that fecklessness on the part of the politicians. There is something inherent in human nature about being overly optimistic in these boom times.

And how do the Austrians solve that? They might say, “Well, we should go to a gold standard so that banks have to back up their deposits with some sort of hard money, precious metals and the like, and that will limit the loans.” Or they argue that in a free market banking system, agents would, on the whole, make more rational decisions. But this is an open question. Maybe it’s an empirical question. Maybe it’s a philosophical question. But you think that the preponderance of evidence is, empirically, on the side of people like Keynes and Minsky, who would still give some role for a wise and benevolent leader at the helm of the Federal Reserve, who could make corrections.

I think I remember a Keynes quote, and I don’t remember the exact quote—this might have been your email signature for a time—but it stuck in my mind, and it was something to the effect of, “We should hope that one day, economists will be as useful as dentists.” It’s “economists as technicians” rather than economists as “worldly philosophers.” People like John Stuart Mill seem to be more in the model of philosophers, but they also had economic theories, and these two things do seem to dovetail. What do you think is the proper role for economists, and are they more like dentists or they more like philosophers?

Brad DeLong: Well, we’re not terribly good as philosophers. As far as philosophers are concerned, we’re either third-rank libertarians or third-rank utilitarians. Or we used to have—I don’t know what you want to call it—third-rank Hegelians, talking about the necessity of freedom and the nurturing of humanity’s species-being, or identity as a species in one way or another. We’re not terribly good at any of those, and I think we’re better when we try to be technicians. Unfortunately, we’re lousy technicians.

Now let’s take this kind of question for example: Keynes, Friedman, Hayek and Minsky are all extremely smart and are all trying extremely hard, and indeed their positions bleed into each other. When Hayek stops talking about government engaging in deficit spending as the [sole] source of the boom that produces the bubble, and then slides over into banks that are improperly regulated for individuals who really do not understand that, say, the fact that Bitcoin has gone from 1,000 to 16,000 this year, does not mean that Bitcoin is likely to rise in the future—then, all of a sudden, Hayek starts moving over into Minsky. And when Keynes talks about how a boom leads to an increase in capital investments, that then reduces the rate of profit that can be earned on new investments, he starts sliding in the direction of Hayek.

Friedman’s hopes that you could make good Federal Reserve policy not automatic, but close to automatic, has pretty much been dashed, and that’s a big victory for Keynes. Keynes’ belief that you could have wise technocrats running the government does not look so hot, and that’s a victory for Minsky. And Hayek’s belief that, in some sense, the bubble is the cause of the depression and that if you avoid the boom in the bubble, you manage to avoid the depression, that really doesn’t look so good these days. Largely, because the two biggest depressions we’ve had in the past century—the 1930s and then the past decade—are far, far greater in magnitude than the previous bubble to which Hayek wants to blame them on. But I was much more of a monetarist 15 years ago than I am now. I thought Friedman looked much better than Keynes, and Minsky worse. Reality has a way of teaching you lessons.

Charlie Deist: Yes, and this is a nuanced perspective. We’re not calling names, or it’s not those bad guy Austrians or those good guy Keynesians. It’s a much more complicated picture with a lot of different shades and overlap between the theories. That’s what I’ve always appreciated about your blog and your writing is that it does seem like an earnest attempt—and even if we might disagree on some philosophical issues, there does seem to be this good faith effort to actually get to the truth. We have a caller on the line, so I want to hear from them and see if we can maybe bring this conversation back to some fundamentals.
Michael, let’s hear your question.

Michael: Hi Charlie. Thanks for a fascinating show. I was going to bring up some fundamentals. When you talk about the Austrian school, a fundamental aspect of it is praxiology, and I was wondering how praxeology fits into the discussion?

Brad DeLong: Praxeology, at least as I understand it, at one level it is sheer and total genius. I was reading a piece last night by three left-wing economists at VoxEu.com—Sam Bowles, Rajiv Sethi, and I’m blanking on the name of the third author. [It] said that Hayek’s decisive and positive contribution to economics was in fact his rejection of Walrasian static, and also general equilibrium theory, as developed by Arrow and Debreu, [along] with the idea that the justification for the market is that it produces the best equilibrium. Because there’s never an equilibrium. Because all human action is a discovery and interaction process, in which people have different plans that are extraordinarily often inconsistent. And it’s the right way to analyze economics, and indeed all social life, is to look at how agents behaving in a disequilibrium situation, learn and react and adapt to each other.

Michael: I think the first step in criticizing praxeology is defining it. So why not just tell the listeners what it consists of.

Charlie Deist: Sure. Thanks, Michael.

Brad DeLong: As I’m saying, that’s my view of what praxiology is.

Charlie Deist: Praxeology being, most simply, the study of human action. Mises, in his book “Human Action” defines—I don’t know if he originated the word—but basically it’s “how do humans act?” It’s not necessarily what should they desire, but given that humans have certain ends, and that they use certain means, what can we say?

Whereas the typical classical economic approach to studying markets doesn’t necessarily begin with these assumptions about human action—these axioms that can be laid out just by going inward and thinking about the structure of the mind. It starts more with what [DeLong] is talking about: this Walrasian idea of an equilibrium (Leon Walras, not to be confused with the marine mammal, was the guy who basically invented supply and demand curves).

You have supply, where people will be induced to produce more of a good if there’s a higher price, and then demand, people will demand more if it’s a lower price. That gives you an upward-sloping supply curve and a downward-sloping demand curve, and where those meet, you have an equilibrium price and quantity. That’s what the market will produce. But, in praxeology, can we use supply and demand curves or do we need a completely different model?

Brad DeLong: Well, we can use supply and demand gingerly, because they do have very stringent underlying assumptions that most of the discovery that is the core of the market process have already been accomplished. I think that view, that rejection of Walrasian general equilibrium as a road that may well mislead us—that’s going to miss most of what is going on—is the very good part of praxeology.

The bad part of praxeology is simply when one tries to reduce what is, after all, an empirical study of how markets behave, to a set of logical consequences of looking inward and trying to assess one’s own motives. Even what I see as the Hayekian side of praxeology moves us towards creating a reified theoretical superstructure that then has little to do with how markets actually operate in the world. So I think the internal, psychological side of praxeology kind of leads away from the world, into another, different, abstract theoretical structure.

That’s why I would prefer to say Hayek rather than the Austrians, because I think Hayek has by far the better of the arguments here. I find Hayek’s viewpoint, which is focused on the market as discovery process, much more congenial to how I think than saying that we will take another step back from empirical reality, and try to derive laws of thought and human action from introspection.

If the psychologists tell us anything, it’s that we’re pretty bad at introspection. We vastly overestimate how smart we are—even how much of the world we see around us—and that can lead us wrong.

Charlie Deist: We should be more humble with regard to what we can know, and I think that the Austrian school tends to emphasize this in one area—mainly with respect to what government can know about the economy and thus what it can manipulate, so it’s very skeptical of the sort of technocratic economist-as-dentist paradigm. But you’re offering, with the same logic, a counterpoint which is that when we try to build our foundations for economics on this logical deduction, based on the logical structure of the human mind, that can also take us in a direction where we might have the overconfident in our models.

Brad DeLong: Did you receive the gorilla basketball video?

Charlie Deist: I believe so, but describe it for our listeners.

Brad DeLong: It was a psychologist’s experiment. They take the students to the professor to be experimented on and they set them in front of a TV screen and they say, “A basketball team is going to come out, and they’re going to practice, and they’re gonna pass the ball to each other, and your job is to count how many times they pass the ball to each other. And we’re trying to assess how smart people are, and how well they can deal with rapid information, so you’re trying to count accurately. And of course, we’ll judge you as if you get it wrong, et cetera, et cetera.”
And so then the basketball team comes out and they begin passing. And after about a minute, a person in a gorilla suit walks into the field of view from the left, slowly, and in the middle of the field of view, he beats his chest, and then walks off to the right, and then the video ends and people report how many times the ball was passed.

And then the experimenter asks, “Was there anything else about the video that struck you as remarkable?” And recorders of the people, they know, and then they say, “Did you notice the gorilla? The person in the gorilla suit?” And two-thirds of the people say no. That always struck me as a statement, not just about how focused humans are on whatever they’re focused on, but also how much we overestimate how aware of what’s going on in the world around us we can possibly be.

You can get the same experience by going to magic shows, by the way, in terms of just how unaware the people they are conducting their tricks on are—how unable to follow everything that’s going on. Especially, if you’re Penn and Teller and you have three different levels of misdirection there.

Charlie Deist: It’s a fascinating example of how we can have these huge blind spots, and it’s another good lesson about the humility that we should bring to any academic or philosophical enterprise. So thank you, Michael ,for your question, and I believe we have another caller on the line. Let’s hear from John.

John: I have a question for the professor. I assume that housing values and stock values represent much of the wealth in America and those values have fluctuated widely in the last ten years from high to low, now to very high. Has our society gotten wealthier or is this purely a monetary phenomenon? I’ll take the answer off the air.

Brad DeLong: Has our society gotten wealthier? Well, I would say yes and no. I would say the best way to look at it right now is that high stock and housing prices more reflect a low expected private rate of return on investment so that companies that have earnings right now, plus some that don’t like Amazon, plus houses that are built and are providing satisfaction to human beings, have a relatively high price relative to currently produced goods and services because there’s little opportunity to build new buildings and take new machines and use them to create enterprises that will be equally profitable. So that in one sense, it reflects not that we’re rich now, so much as though we’re not expected to become that much richer, faster in the future.

And you can go down to Silicon Valley and find Google’s Chief Economist Hal Varian, and he’ll say that what’s really going on is we’re becoming more prosperous at an amazing rate. Look at how much people like their cell phones, look at access to information and communication. It’s just that these particular sources of human well-being are not ones that are really being created and transferred by the market process. That is, that rather than selling what it produces, which is information, Google is running off of the fumes created by selling your eyeballs to advertisers, and the value it earns by selling your eyeballs to advertisers is much, much less than the value you receive from the access to information that Google gives you.

So, the fact that it isn’t expected that future investments will be very profitable doesn’t mean that they won’t be very productive or very welfare-enhancing, but Hal is a minority point. The majority point is that we seem to have entered a world in which people are less optimistic about the future of economic growth than they were. That’s the thing that’s pushing up housing prices, and currently installed housing prices and current stock prices, because those companies have made their investment.

And what it’s really saying is investments in the past were more valuable than the investments you make today, and that’s why they’re so high.

There’s a second sense in which high housing prices in greater San Francisco are a sign of our poverty. That is, in a better functioning world—in a world without my crazy NIMBY neighbors, there’d be no way that a house like mine—a mile south of the University, a mile north of the Rockridge BART—there’s no way that the neighborhood of Elmwood now would still be composed overwhelmingly of houses like mine rather than of triple-deckers like the small apartment buildings surrounding Harvard, or like the ten-story apartment buildings surrounding Columbia, or like the 25-story stuff surrounding NYU. But [given] the population of greater San Francisco, if San Francisco development in the land of Silicon Valley had followed the standard American pattern, we’d have seen its population grow from five million to ten million over the past 25 years.

Instead, it’s only grown from five to 6.5 million due to NIMBY development restraints.

And that means that the houses that exist are extremely valuable. But the reason they’re so valuable is because they’re so scarce. It’s a monopoly rent. And we’re poorer by the fact that we ought to have 3.5 million dwelling units in greater San Francisco that we do not have because we have seriously screwed up our land-use governance over the past 25 years. So.. all of this is a standard economist’s answer: on the one hand, on the other hand; yes and no.

Charlie Deist: Right. Another axiom that economists are fond of is that there are always trade-offs. One of the points that the Austrians maybe internalized, but maybe still have a ways to go in incorporating into their thinking is the idea that planning has to take place at some level. There’s no such thing as a purely neutral zoning policy, for example, and if we want to come up with the ideal regulations, well, maybe there is no such thing as an ideal regulation, because there will always be trade-offs. So economists have to be the wet blankets to inform people that they can’t have everything that they want.

Sadly we’re coming close to the end of the hour.I’m speaking with professor Brad DeLong. He is at UC Berkeley, where he is the chair of the political economy department. He’s also a visiting scholar at the Federal Reserve Bank in San Francisco and served as deputy assistant secretary at the U.S. Treasury, so he’s an expert in the matters of monetary policy as well as economic history and a variety of other things.

I wish I could pick his brain all morning, but in these last ten minutes, I want to come back to what you were saying about Hal Varian and this world that we’re entering, where more of the value is coming from our smartphone technology, from information technology. On the one hand, this can give us an incredible amount of satisfaction. I’ve found blogs and Twitter and all these things to be a source of incredible education. But at the same time, they can also be… it’s a mixed bag. And in this new economic system, maybe there’s less emphasis on physical stuff and things.

But the Austrian business cycle theory places a big emphasis on these long-term capital malinvestments—these are the areas where we tend to see inflation having the greatest effect. We get inflation from the long-term areas because cheap credit encourages a sort of … Hayek talks about the structure about production, meaning certain investments take longer to materialize … and if we’re injecting money into credit markets first, then you will tend to incentivize people to develop longer-term things.

Is there any kind of application for that model in your mind to the current world that we live in?

Most of these Austrians were writing well before the 1960s. Hayek and Mises were early 20th-century economists. Is there anyone doing work in your mind that brings these ideas into the 21st century? Or, what areas do you think would be most fruitful for someone who is interested in an Austrian approach to focus on, without getting to thick into the weeds?

Brad DeLong: Well, with respect to that of over-investment in the structure production, I think the Minskyist current is winning and is the most productive one to pursue now. That is, if you’ve made investments and if you did make them assuming long-term interest rates will be lower than they in fact are now, and if they are now unprofitable, that doesn’t mean we should shut them down. To say we should shut them down is the sunk cost fallacy, to which I think Hayek and Von Mises fell subject to, to a large degree. What it does mean is that our future investments should be focused on things that have short-term payoff.

Then the question is, “Well, if we shouldn’t shut down long-term investments that are now unprofitable because we’ve already made them (and we might as well get something out of them), why is the reaction to a period of prolonged sub-normal interest rates a depression?”

And the Minskyite answer is that it’s the financial system that messes up. That there’s no good way to quickly allocate the losses. The core of it is the fact that losses have not been allocated, and people wanting to commit new money are scared their new money will go to pay for old losses.
And that, I think, is a very fruitful line of investigation—that it’s not so much a hangover of excess buildings and excess machines, because we can always find uses for buildings and machines. It’s a hangover of bad assets—of bad debt that somebody is going to have to pay, or swallow and eat—and social disagreement over who has to eat them.

So, I would say investigating the structure of bankruptcy and principal–agency finance, and how to quickly resolve situations in which debts go bad is the most fruitful thing to pursue.

If I can also give a commercial?

Charlie Deist: Absolutely.

Brad DeLong: I had dinner last week in San Francisco with a guy named Jerry Taylor, who used to be a vice president at the Cato Institute, and he now has split off and has his own libertarian think tank called the Niskanen Center in Washington D.C., which has a lot of smart people doing a lot of interesting thinking. If you’re looking for a set of people thinking and arguing about libertarian ideas in the 21st Century, and want to put them on your Christmas list, I think the Niskanen Center ought to be first among your choices.

Charlie Deist: Those who listen to this show know that we often host guests from the Cato Institute—sometimes we’ll have a month where half our guests or more will come from Cato. Jerry Taylor, as Brad DeLong is mentioning, is someone who fits that mold, but he has come up with a new intellectual venture. This is the Niskanen Center, and they are producing ideas—would you characterize them as a moderate, centrist, technocratic Libertarian perspective or … what is their byline or subtitle?

Brad DeLong: Their byline is to explode the center and to kind of ask, “What does libertarian mean, not in the 19th, not in the 20th, but in the 21st century?”

Charlie Deist: I had also hoped to ask you—this is one of those questions that I could talk about for hours, and we’ll just have to keep it to a few minutes—but to your mind, what is the different between a liberal and a classical liberal, and do you identify as one or the other, or both?

Brad DeLong: The shortest way I’d put it is:

Suppose you’re locked in a cage and suppose there’s a key that someone outside the cage is holding. The classical liberal would say, “You’re free as long as there’s a key and there’s somebody you could buy it from.” A New Deal liberal would say, “Wait a minute, you’re only free if you have the money to buy the key from the person holding it.”

I would say I’d identify myself as a modern liberal—a New Deal liberal—for that reason, but I’d also say that New Deal liberals, traditionally, have an appalling disregard for the magnitude of government failure and for the damage caused to the economy by rent seeking.

If I find myself in a group of too many social democrats, I’ll actually start calling myself a neoliberal. And if I find myself in a group of too many liberals, I’ll start calling myself a social democrat.

Charlie Deist: So kind of a natural contrarian—I like that.

We’re gonna have to cut off my conversation here. If you are interested in following Brad DeLong’s work, you can find him at bradford-delong.com. He’s also on Twitter at @delong. And once again, I’m Charlie Deist, filling in for Bob, who will be back next week.

We’ve just spent the hour discussing the Austrian theory of the business cycle, in contrast with the Keynesian perspective, as well as the Friedmanite, the Minskyist, and there’s probably many other perspectives that we didn’t get to. This is an area that anyone who’s interested can get online and do their own homework, and form their own conclusions. We’ve been fortunate to have someone who has a nuanced perspective, and can treat this issue with the full intellectual weight it deserves. So stay tuned next week, Bob will be back. And you can always catch this episode and any others at bobzadek.com. Once again, thanks Brad for taking the time to talk with me.

Brad DeLong: You’re welcome. It’s been a great pleasure.

Charlie Deist: Alright, well have a great rest of your day and to all the listeners out there, enjoy the weekend. We’ll talk to you soon.

Correct Predictions and the Status of Economists: Hoisted from the Archives from Three Years Ago

Bradford delong com Grasping Reality with the Invisible Hand

Brad DeLong (2013): Correct Predictions and the Status of Economists:

Paul Krugman is certainly right that history has judged… for James Tobin over Milton Friedman. There is not even a smudge left where Friedman’s approach to a monetary theory of nominal income determination once stood….

Robert Waldmann points out, repeatedly and correctly, that there is nothing theoretically in Friedman (1967) that is not in Samuelson and Solow (1960)–that inflation above expectations might deanchor future inflation was not something Friedman (or Phelps) thought up, and that neither Friedman (nor Phelps) was thinking that high unemployment might deanchor the NAIRU. And Paul Krugman points out that the vertical long-run Phillips Curve of Friedman (and Phelps) is simply wrong at low rates of inflation, and so not helpful as a fundamental tool.

There is, however, one big thing Friedman got right: to stand up on his hind legs and say: ‘Expectations of inflation are becoming deanchored right now. The accelerationist mechanism is the mechanism that is going to dominate business cycle dynamics in both the short-term and the medium-term.’ That was right. And that was a powerful source of manna.

Similarly, or perhaps not, I would argue that there is one big thing (along with a large number of medium things and small things) that Paul Krugman got right: his prediction back in 1998 of The Return of Depression of Economics. Yet somehow Uncle Paul has not gained a similar amount of manna to what Uncle Milton gained in the late 1960s…


UPDATED 2016: And I note that Larry Summers has a similar extremely large important macroeconomic empirical hit with his predictions half a decade ago that not just “depression economics” but secular stagnation was something that we need to take very seriously indeed. I’m watching to see what the community makes of this…

…in which he nominated Milton Friedman’s corpse for Fed chairman. Before learning that Friedman was dead, Paul did concede that he wasn’t an Austrian. But I’ll bet he had no idea about the extent to which Friedman really, really wasn’t an Austrian. In his ‘Comments on the critics’ (of his Monetary Framework) Friedman described the ‘London School (really Austrian) view’

that the depression was an inevitable result of the prior boom, that it was deepened by the attempts to prevent prices and wages from falling and firms from going bankrupt, that the monetary authorities had brought on the depression by inflationary policies before the crash and had prolonged it by ‘easy money’ policies thereafter; that the only sound policy was to let the depression run its course, bring down money costs, and eliminate weak and unsound firms.

and dubbed this view an ‘atrophied and rigid caricature’ of the quantity theory. [His version of the] Chicago School, he claimed, never believed in such nonsense. I have, incidentally, seen attempts [by Larry White and company] to claim that nobody believed this, or at any rate that Hayek never believed this, and that characterizing Hayek as a liquidationist is some kind of liberal libel. This is really a case of who are you gonna believe, me or your lying eyes. Let’s go to the text (pdf), p. 275:

And, if we pass from the moment of actual crisis to the situation in the following depression, it is still more difficult to see what lasting good effects can come from credit expansion. The thing which is needed to secure healthy conditions is the most speedy and complete adaptation possible of the structure of production to the proportion between the demand for consumers’ goods and the demand for producers’ goods as determined by voluntary saving and spending.

If the proportion as determined by the voluntary decisions of individuals is distorted by the creation of artificial demand, it must mean that part of the available resources is again led into a wrong direction and a definite and lasting adjustment is again postponed. And, even if the absorption of the unemployed resources were to be quickened in this way, it would only mean that the seed would already be sown for new disturbances and new crises. The only way permanently to ‘mobilize’ all available resources is, therefore, not to use artificial stimulants—whether during a crisis or thereafter—but to leave it to time to effect a permanent cure by the slow process of adapting the structure of production to the means available for capital purposes.

And so, at the end of our analysis, we arrive at results which only confirm the old truth that we may perhaps prevent a crisis by checking expansion in time, but that we can do nothing to get out of it before its natural end, once it has come…

If that’s not liquidationism, I’ll eat my structure of production…

Must-read: David Glasner: “What’s Wrong with Monetarism?”

Must-Read: An excellent read from the very sharp David Glasner. I, however, disagree with the conclusion: the standard reaction of most economists to empirical failure is to save the phenomena and add another epicycle. Why not do that in this case too? Why not, as someone claimed to me that John Taylor once said, stabilize nominal GDP by passing a law mandating the Federal Reserve keep velocity-adjusted money growing at a constant rate?

David Glasner: What’s Wrong with Monetarism?: “DeLong balanced his enthusiasm for Friedman with a bow toward Keynes…

…noting the influence of Keynes on both classic and political monetarism, arguing that, unlike earlier adherents of the quantity theory, Friedman believed that a passive monetary policy was not the appropriate policy stance during the Great Depression; Friedman famously held the Fed responsible for the depth and duration of what he called the Great Contraction… in sharp contrast to hard-core laissez-faire opponents of Fed policy, who regarded even the mild and largely ineffectual steps taken by the Fed… as illegitimate interventionism to obstruct the salutary liquidation of bad investments, thereby postponing the necessary reallocation of real resources to more valuable uses…. But both agreed that there was no structural reason why stimulus would necessarily counterproductive; both rejected the idea that only if the increased output generated during the recovery was of a particular composition would recovery be sustainable. Indeed, that’s why Friedman has always been regarded with suspicion by laissez-faire dogmatists who correctly judged him to be soft in his criticism of Keynesian doctrines….

Friedman parried such attacks… [saying that] the point of a gold standard… was that it makes it costly to increase the quantity of money. That might once have been true, but advances in banking technology eventually made it easy for banks to increase the quantity of money without any increase in the quantity of gold… True, eventuaally the inflation would have to be reversed to maintain the gold standard, but that simply made alternative periods of boom and bust inevitable…. If the point of a gold standard is to prevent the quantity of money from growing excessively, then, why not just eliminate the middleman, and simply establish a monetary rule constraining the growth in the quantity of money? That was why Friedman believed that his k-percent rule… trumped the gold standard….

For at least a decade and a half after his refutation of the structural Phillips Curve, demonstrating its dangers as a guide to policy making, Friedman continued treating the money multiplier as if it were a deep structural variable, leading to the Monetarist forecasting debacle of the 1980s…. So once the k-percent rule collapsed under an avalanche of contradictory evidence, the Monetarist alternative to the gold standard that Friedman had persuasively, though fallaciously, argued was, on strictly libertarian grounds, preferable to the gold standard, the gold standard once again became the default position of laissez faire dogmatists…. So while I agree with DeLong and Krugman (and for that matter with his many laissez-faire dogmatist critics) that Friedman had Keynesian inclinations which, depending on his audience, he sometimes emphasized, and sometimes suppressed, the most important reason that he was unable to retain his hold on right-wing monetary-economics thinking is that his key monetary-policy proposal–the k-percent rule–was empirically demolished in a failure even more embarrassing than the stagflation failure of Keynesian economics. With the k-percent rule no longer available as an alternative, what’s a right-wing ideologue to do? Anyone for nominal gross domestic product level targeting (or NGDPLT for short)?

More musings on the fall of the house of Uncle Milton…

This, from Paul Krugman, strikes me as… inadequate:

Paul Krugman: Why Monetarism Failed: “Right-wingers insisted–Friedman taught them to insist–that government intervention was always bad, always made things worse…

…Monetarism added the clause, ‘except for monetary expansion to fight recessions.’ Sooner or later gold bugs and Austrians, with their pure message, were going to write that escape clause out of the acceptable doctrine. So we have the most likely non-Trump GOP nominee calling for a gold standard, and the chairman of Ways and Means demanding that the Fed abandon its concerns about unemployment and focus only on controlling the never-materializing threat of inflation.

What about the reformicons, who pushed for neo-monetarism? We can sum up their fate in two words: Marco Rubio. There is no home for the kind of return to realism they were seeking…. The monetarist idea no longer serves any useful purpose, intellectually or politically. Hicksian macro–IS-LM or something like it–remains an extremely useful tool of both analysis and policy formulation; that tool is not helped by trying to state it in terms of monetary velocity and all that. And if you want macro policy that isn’t dictated by Ayn Rand logic, you have to turn to a Democrat; on the other side, there’s nobody rational to talk to.

Sad!

This is an issue I have worried at like a dog at a worn-out glove for a decade now. So let me worry at it again:

There were gold bugs and Austrians in the 1950s, 1960s, 1970s, and even 1980s too. But Arthur Burns, Milton Friedman, Alan Greenspan and company kicked them up and down the street with gay abandon. And the Ordoliberal Germans would, when you cornered them, would admit that somebody else had to take on the job of stabilizing aggregate demand for the North Atlantic economy as a whole for their doctrines to work.

But in 2009 the Lucases and the Prescotts and the Cochranes and the Famas and the Boldrins and the Levines and the Steils and the Taylors and all the others and even the Zingaleses (but we can excuse Luigi on the grounds that if you are (a) Italian and (b) view Berlusconi as the modal politician a certain reluctance to engage in fiscal policy is understandable)–crawled out from their caves and stood in the light of day. And the few remaining students of Milton Friedman got as little respect as the Stewards of Gondor gave to the leaders of the Dunedain.

Yes, there is an intellectual tension between believing in laissez faire as a rule and believing in activist monetary management to set the market interest rate equal to the Wicksellian neutral interest rate. But why is that tension unsustainable? Once you have swallowed a government that assigns property rights, sustains contracts, and enforces weights and measures, why is this extra step a bridge too far?

Yes, in some (many) ways, our macro debate has lost intellectual ground since the 1930s. Why do you ask?

Last September, the illustrious Simon Wren-Lewis wrote a nice piece about the Bank of England’s thinking about Quantitative Easing: Haldane on Alternatives to QE, and What He Missed Out.

Simon’s bottom line was that Haldane was not just thinking inside the box, but restricting his thinking to a very small corner of the box:

[neither] discussion of the possibility that targeting something other than inflation might help… [nor] any discussion of helicopter money…

And this disturbs him because:

We rule out helicopter money because its undemocratic, but we rule out a discussion of helicopter money because ordinary people might like the idea…. Governments around the world have gone for fiscal contraction because of worries about the immediate prospects for debt. It is not as if the possibility of helicopter money restricts the abilities of governments in any way…. [While] it is good that some people at the Bank are thinking about alternatives to QE, which is a lousy instrument…. It is a shame that the Bank is not even acknowledging that there is a straightforward and cost-free solution…

It disturbs me too.

One reason it disturbs me is that a version of “helicopter money” was one of the policy options that Milton Friedman and Jacob Viner endorsed as the right policies to deal with the last time we were at the zero lower bound, stock Great Depression. Back in 2009 I quoted Milton Friedman (1972), “Comments on the Critics of ‘Milton Friedman’s Monetary Framework'”, quoting Jacob Viner (1933):

The simplest and least objectionable procedure would be for the federal government to increase its expenditures or to decrease its taxes, and to finance the resultant excess of expenditures over tax revenues either by the issue of legal tender greenbacks or by borrowing from the banks..

And Friedman continued:

[Abba] Lerner was trained at the London School of Economics [stock 1930s], where the dominant view was that the depression was an inevitable result of the prior [speculative] boom, that it was deepened by the attempts to prevent prices and wages from falling and firms from going bankrupt, that the monetary authorities had brought on the depression by inflationary policies before the crash and had prolonged it by “easy money” policies thereafter; that the only sound policy was to let the depression run its course, bring down money costs, and eliminate weak and unsound firms…. It was [this] London School (really Austrian) view that I referred to in my “Restatement” when I spoke of “the atrophied and rigid caricature [of the quantity theory] that is so frequently described by the proponents of the new income-expenditure approach and with some justice, to judge by much of the literature on policy that was spawned by the quantity theorists” (Friedman 1969, p. 51).

The intellectual climate at Chicago had been wholly different. My teachers… blamed the monetary and fiscal authorities for permitting banks to fail and the quantity of deposits to decline. Far from preaching the need to let deflation and bankruptcy run their course, they issued repeated pronunciamentos calling for governmental action to stem the deflation-as J. Rennie Davis put it:

Frank H. Knight, Henry Simons, Jacob Viner, and their Chicago colleagues argued throughout the early 1930’s for the use of large and continuous deficit budgets to combat the mass unemployment and deflation of the times (Davis 1968, p. 476)… that the Federal Reserve banks systematically pursue open-market operations with the double aim of facilitating necessary government financing and increasing the liquidity of the banking structure (Wright 1932, p. 162)….

Keynes had nothing to offer those of us who had sat at the feet of Simons, Mints, Knight, and Viner. It was this view of the quantity theory that I referred to in my “Restatement” as “a more subtle and relevant version, one in which the quantity theory was connected and integrated with general price theory and became a flexible and sensitive tool for interpreting movements in aggregate economic activity and for developing relevant policy prescriptions” (Friedman 1969, p. 52). I do not claim that this more hopeful and “relevant” view was restricted to Chicago. The manifesto from which I have quoted the recommendation for open-market operations was issued at the Harris Foundation lectures held at the University of Chicago in January 1932 and was signed by twelve University of Chicago economists. But there were twelve other signers (including Irving Fisher of Yale, Alvin Hansen of Minnesota, and John H. Williams of Harvard) from nine other institutions’…

“Helicopter money”–increases in the money stock used not to buy back securities but instead to purchase assets that are very bad substitutes for cash like the consumption expenditures of households, roads and bridges, the human capital of 12-year-olds, and biomedical research–could be mentioned as a matter of course as a desirable policy for dealing with an economy at the zero lower bound by Jacob Viner in 1933. But, apparently, central banks do not even want to whisper about the possibility. One interpretation is that, confronted with Treasury departments backed by politicians and elected by voters that have a ferocious and senseless jones for austerity even though g > r, central banks fear that any additional public recognition by them that fiscal and monetary policy blur into each other may attract the Eye of Austerity and so limit their independence and freedom of action.

If I were on the Federal Reserve Board of Governors or in the Court of the Bank of England right now, I would be taking every step to draw the line between fiscal policy and monetary policy sharply, but I would draw it in the obvious place:

  • Contractionary fiscal policies seek to lower the government debt (but with g > r or even g near r and hysteresis actually raise the debt-to-GDP ratio and possibly the debt).
  • Expansionary fiscal policies seek to raise the government debt (but with g > r or even g near r and hysteresis actually lower the debt-to-GDP ratio and possibly the debt).
  • Policies that neither raise or lower the debt ain’t fiscal policy, they are monetary policy.
  • Contractionary monetary policies reduce the money stock (and usually but do not have to raise the stock of government debt held by the private sector).
  • Expansionary monetary policies raise the money stock (and usually but do not have to lower the stock of government debt held by the private sector).

And if helicopter money leads Treasuries to protest that the money stock is growing too rapidly? (They cannot, after all, complain that the government debt stock is growing too rapidly because it isn’t.) The response is: Who died and put you in charge of monetary inflation-control policy? That’s not your business.

Why Not the Gold Standard? Hoisted from the Archives from 1996

Witwatersrand mines Google Search

From 1996: Why Not the Gold Standard? Talking Points on the Likely Consequences of Re-Establishment of a Gold Standard:

Consequences for the Magnitude of Business Cycles:

Loss of control over economic policy: If the U.S. and a substantial number of other industrial economies adopted a gold standard, the U.S. would lose the ability to tune its economic policies to fit domestic conditions.

  • For example, in the spring of 1995 the dollar weakened against the yen. Under a gold standard, such a decline in the dollar would not have been allowed: instead the Federal Reserve would have raised interest rates considerably in order to keep the value of the dollar fixed at its gold parity, and a recession would probably have followed.

Recessionary bias: Under a gold standard, the burden of adjustment is always placed on the ‘weak currency’ country.

  • Countries seeing downward market pressure on the values of their currencies are forced to contract their economies and raise unemployment.
  • The gold standard imposes no equivalent adjustment burden on countries seeing upward market pressure on currency values.
  • Hence a deflationary bias, which makes it likely that a gold standard regime will see a higher average unemployment rate than an alternative managed regime.

The gold standard and the Great Depression: The current judgment of economic historians (see, for example, Barry J. Eichengreen, Golden Fetters is that attachment to the gold standard played a major part in keeping governments from fighting the Great Depression, and was a major factor turning the recession of 1929-1931 into the Great Depression of 1931-1941.

  • Countries that were not on the gold standard in 1929–or that quickly abandoned the gold standard–by and large escaped the Great Depression
  • Countries that abandoned the gold standard in 1930 and 1931 suffered from the Great Depression, but escaped its worst ravages.
  • Countries that held to the gold standard through 1933 (like the United States) or 1936 (like France) suffered the worst from the Great Depression
  • Commitment to the gold standard prevented Federal Reserve action to expand the money supply in 1930 and 1931–and forced President Hoover into destructive attempts at budget-balancing in order to avoid a gold standard-generated run on the dollar.
  • Commitment to the gold standard left countries vulnerable to ‘runs’ on their currencies–Mexico in January of 1995 writ very, very large. Such a run, and even the fear that there might be a future run, boosted unemployment and amplified business cycles during the gold standard era.
  • The standard interpretation of the Depression, dating back to Milton Friedman and Anna Schwartz’s Monetary History of the United States, is that the Federal Reserve could have, but for some mysterious reason did not, boost the money supply to cure the Depression; but Friedman and Schwartz do not stress the role played by the gold standard in tieing the Federal Reserve’s hands–the ‘golden fetters’ of Eichengreen.
  • Friedman was and is aware of the role played by the gold standard–hence his long time advocacy of floating exchange rates, the antithesis of the gold standard.

Consequences for the Long-Run Average Rate of Inflation:

Average inflation determined by gold mining: Under a gold standard, the long-run trajectory of the price level is determined by the pace at which gold is mined in South Africa and Russia.

  • For example, the discovery and exploitation of large gold reserves near present-day Johannesburg at the end of the nineteenth century was responsible for a four percentage point per year shift in the worldwide rate of inflation–from a deflation of roughly two percent per year before 1896 to an inflation of roughly two percent per year after 1896. In the election of 1896, William Jennings Bryan’s Democrats called for free coinage of silver as a way to end the then-current deflation and stop the transfer of wealth away from indebted farmers. The concurrent gold discoveries in South Africa changed the rate of drift of the price level, and accomplished more than the writers of the Democratic platform could have dreamed, without any change in the U.S. coinage.
  • Thus any political factors that interrupted the pace of gold mining would have major effects on the long-run trend of the price level–send us into an era of slow deflation, with high unemployment. Conversely, significant advances in gold mining technology could provide a significant boost to the average rate of inflation over decades. Under the gold standard, the average rate of inflation or deflation over decades ceases to be under the control of the government or the central bank, and becomes the result of the balance between growing world production and the pace of gold mining.

Why Do Some Still Advocate a Gold Standard?

  • A belief that governments and central banks should not control the average rate of inflation over decades, and that the world will be better off if the long-run drift of the price level is determined ‘automatically.’
  • A belief that bondholders and investors will be reassured by a government committed to a gold standard, will be confident that inflation rates will be low, and so will bid down nominal interest rates.
  • Of course, if you do not trust a central bank to keep inflation low, why should you trust it to remain on the gold standard for generations? This large hole in the supposed case for a gold standard is not addressed.
  • Failure to recognize the role played by the gold standard in amplifying and propagating the Great Depression.
  • Failure to recognize that the international monetary system functions best when the burden-of-adjustment is spread between balance-of-payments ‘surplus’ and ‘deficit’ countries, rather than being loaded exclusively onto ‘deficit’ countries.
  • Failure to recognize how gold convertibility increases the likelihood of a run on the currency, and thus amplifies recessions.

Cracking the Hard Shell of the Macroeconomic Knut: “Keynesian”, “Friedmanite”, and “Wicksellian” Epistemes in Macroeconomics

The very-sharp Tyler Cowen gets one, I think, more wrong than right. He writes:

Tyler Cowen: What’s the Natural Rate of Interest?: “I… find all this talk of natural rates of interest…

…historically strange. A few points: (1) David Davidson and Knut Wicksell debated the… concept very early in the twentieth century, in Swedish…. Most people believe Davidson won…. (2) Keynes devoted a great deal of effort to knocking down the natural rate of interest…. There could be multiple natural rates… [or] no rate of interest whatsoever…. (3) In postwar economics, the Keynesians worked to keep natural rates of interest concepts out….

(4) The older natural rate of interest used to truly be about price stability… [not] “two percent inflation a year.”… (5) Milton Friedman warned (pdf) not to assign too much importance to interest rates…. (6) When Sraffa debated Hayek and argued the natural rate of interest was not such a meaningful concept, it seems Sraffa won…. (7) I sometimes read these days that the “natural [real] rate of interest” consistent with full employment is negative. To me that makes no sense in a world with positive economic growth and a positive marginal productivity of capital….

Of course economic theory can change, and if the idea of a natural rate of interest makes a deserved comeback we should not oppose that development per se. But I don’t see that these earlier conceptual objections have been rebutted, rather there is simply now a Kalman filter procedure for coming up with a number…. In any case, this is an interesting case study of how weak or previously rebutted ideas can work their way back into economics. I don’t object to what most of the people working on this right now actually are trying to say. Yet I see the use of the term acquiring a life of its own, and as it is morphing into common usage some appropriately modest claims are taking on an awful lot of baggage from the historical connotations of the term…

In my view, all (7) of these are more than debatable. For example, (7): “[That] the ‘natural [real] rate of interest’ consistent with full employment is negative… makes no sense in a world with positive economic growth and a positive marginal productivity of capital…” misses the wedge–the wedge between the (positive) expected real rate of return from risky investments in capital and the (positive) temporal slope to the expected inverse marginal utility of consumption, on the one hand; and the (negative) equilibrium real low-risk interest rate, on the other hand.

In a world that is all of a global savings-glut world with large actors seeking portfolios that provide them with various kinds of political risk insurance, risk-tolerance gravely impaired by the financial crisis and the resulting deleveraging debt supercycle, moral hazard that makes the remobilization of societal risk-bearing capacity difficult and lengthly, and reduced demographic and technological supports for economic growth, it seems to me highly plausible that this wedge can be large enough to make the low-risk ‘natural [real] rate of interest’ consistent with full employment negative alongside positive economic growth and a positive marginal productivity of capital.

And the bond market agrees with me in email:

Graph Long Term Government Bond Yields 10 year Main Including Benchmark for Germany© FRED St Louis Fed Graph 10 Year Treasury Inflation Indexed Security Constant Maturity FRED St Louis Fed

And (2): “Keynes devoted a great deal of effort to knocking down the natural rate of interest…” Indeed he did Keynes saw the natural rate of interest as part of a wrong loanable-funds theory of interest rates: that, given the level of spending Y, supply-and-demand for bonds determined the interest rate. Keynes thought that people must reject that wrong theory before they could adopt what he saw as the right, liquidity-preference, theory of interest rates: that, given the level of spending Y and the speculative demand for money S, supply-and-demand for money determined the interest rate.

I think Keynes was wrong. I think Keynes made an analytical mistake.

Hicks (1937) established that Keynes was wrong when he believed that you had to choose. You don’t. Because spending Y is not given but is rather jointly determined with the interest rate, you can do both. Indeed, you have to do both. Liquidity-preference without loanable-funds is just one blade of the scissors: it cannot tell you what the interest rate is. And loanable-funds without liquidity-preference is just the other blade of the scissors: it, too, cannot tell you what the interest rate is. You need both.

More important, however, in thinking about our present concern with the natural (“neutral”) (“equilibrium”) real rate of interest is knowledge of the historical path by which we arrived at our current intellectual situation. Alan Greenspan did it. On July 20, 1994, Alan Greenspan announced that the Federal Reserve was not a “Keynesian” institution, focused on getting the volume of the categories of aggregate demand–C, I, G, NX–right. He announced that the Federal Reserve was not a “Friedmanite” institution, focused on getting the quantity of money right. He announced that the Federal Reserve was now a “Wicksellian” institution, focused on getting the configuration of asset prices right:

Alan Greenspan (1994): Testimony before the Subcommittee on Economic Growth and Credit Formation of the Committee on Banking, Finance and Urban Affairs, U S House of Representatives, July 20: “The FOMC, as required by the Humphrey-Hawkins Act…

…set[s] ranges for the growth of money and debt…. M2 has been downgraded as a reliable indicator…. [The] relationship between M2 and prices that could anchor policy over extended periods of time… [has] broken down…. M2 and P-star may reemerge as reliable indicators of income and prices….

In the meantime… in assessing real rates [of interest], the central issue is their relationship to an equilibrium interest rate, specifically the real rate level that, if maintained, would keep the economy at its production potential over time. Rates persisting above that level, history tells us, tend to be associated with slack, disinflation, and economic stagnation–below that level with eventual resource bottlenecks and rising inflation, which ultimately engenders economic contraction. Maintaining the real rate around its equilibrium level should have a stabilizing effect…. The level of the equilibrium real rate… [can] be estimated… [well] enough to be useful for monetary policy…. While the guides we have for policy may have changed recently, our goals have not…

Greenspan thus shifted the focus of America’s macroeconomic discussion away from the level of spending and the quantity of money to the configuration of asset prices. In some ways this is no big deal: “Keynesian”, “Friedmanite”, and “Wicksellian” frameworks are all perfectly-fine ways to think about macroeconomic policy. They are different–some ideas and some factors are much easier to express and focus on and are much more intuitive in one of the frameworks than in the others. But they are not untranslateable–I have not found any point that you can express in one framework that cannot be more-or-less adequately translated into the others.

The point, after all, is to find a macroeconomic policy that will make Say’s Law, false in theory, true enough in practice for government work. You can start this task by focusing your analysis first on either spending, or liquidity, or the slope of the intertemporal price structure. You will almost surely have to dig deeper into the guts of the economy in order to understand why the current emergent macro properties of the system are what they are. But any one of the languages will do as a place to start. Greenspan in the mid-1990s judged that the Wicksellian language provided the best way to communicate. And, looking back over the past 25 years, I cannot really disagree.

But at the time, back in 1994, the shift to a Wicksellian episteme led to substantial confusion. As I remember it, I spent my lunchtime on July 20, 1994, seated at my computer in my office on the third floor of the U.S. Treasury, frantically writing up just what Alan Greenspan was talking about when he said (1) pay no attention to Federal Reserve policy forecasts of M2; instead, (2) pay attention to our assessments of the relationship of interest rates to an equilibrium interest rate. Greenspan announced that the Fed was no longer asking in a Friedmanite mode “do we have the right quantity of money?”, but rather was asking in a Wicksellian mode “do we have the right configuration of interest rates”. And that still does not seem to me to be a bad place to be.

Central Banks Are Not Agricultural Marketing Boards: Depression Economics, Inflation Economics and the Unsustainability of Friedmanism

Central Banks Are Not Agricultural Marketing Boards: Depression Economics, Inflation Economics and the Unsustainability of Friedmanism

Insofar as there is any thought behind the claims of John Taylor and others that the Federal Reserve is engaged in “price controls” via its monetary policy actions.

Strike that.

There is no thought at all behind such claims at all.

Insofar as one did want to think, and so construct an argument that the Federal Reserve’s monetary policy operations are destructive and in some ways analogous to “price controls”, the argument would go something like this:

The Federal Reserve’s Open Market Committee’s operations are like those of an agriculture marketing board–a government agency that sets the price for, say, some agricultural product like butter or milk. Some of what is offered for sale at that price that is not taken up by the private market, and the rest is bought by the government to keep the price at its target. And the next month the government finds it must buy more. And more. And more.

Such policies produce excess supplies that then must be stored or destroyed: they produce butter mountains, and milk lakes.

The resources used to produce the butter mountains and milk lakes is wasted–it could be deployed elsewhere more productively. The taxes that must be raised to pay for the purchase of the butter and milk that makes up the mountains and the lakes discourages enterprise and employment elsewhere in the economy, and makes us poorer. Taxes are raised (at the cost of an excess burden on taxpayers) and then spent to take the products of the skill and energy of workers and… throw them away. Much better, the standard argument goes, to eliminate the marketing board, let the price find its free-market equilibrium value, provide incentives for people to move out of the production of dairy products into sectors where private demand for their work exists, and keep taxes low.

Now you can see that a central bank is exactly like an agricultural marketing board, except for the following little minor details:

  1. An agricultural marketing board must impose taxes to raise the money finance its purchases of butter and milk. A central bank simply prints–at zero cost–the money to finance its purchase of bonds.
  2. The butter mountains and milk lakes that the agricultural marketing board owns cannot be sold without pushing the price down below its free-market equilibrium and thus negating the purpose of the board. A central bank does not want to sell its bond mountains, but merely to collect interest and hold them to maturity, at which point they are simply money mountains.
  3. The butter mountains and milk lakes are useless for the agricultural marketing board: all it can do with them is simply watch them rot away. The bond mountain turns into a money mountain–seigniorage–which the central bank then gives to the government, which lowers taxes as a result.

So a central bank is exactly like an agricultural marketing board–NOT!!! They are identical–except that they are completely different.

But, somewhat smarter John Taylor and others might say, a central bank is like an agricultural marketing board. The extra money it puts into circulation when its bonds mature and it transfers profits to the government devalue and debauch the currency. It raises the real resources needed to finance its bond purchases by levying an “inflation tax” on money holders–by reducing the value of their cash just as an income tax reduces the (after-tax) value of incomes.

And I would agree, if the inflation comes. Under conditions of what I like to call Inflation Economics, money-printing and bond purchases do push the interest rate below the natural rate of interest–push bond prices above their natural price–as defined by Knut Wicksell. Money-printing and bond purchases then do indeed cause economic problems somewhat analogous to those of a marketing board that keeps the prices of butter and milk above their natural price.

But what if the inflation does not come? What if our economy’s phase is one of not Inflation Economics but Depression Economics, in which the central bank is not pushing the interest rate below its Wicksellian natural rate but is instead stuck trying to manage a situation in which the Wicksellian natural rate of interest is less than zero?

Then the analogies break down completely. Money-printing is then not an inflationary tax but instead a utility-increasing provision of utility services. Bond purchases do not create an overhang that cannot be sold without creating an opposite distortion from the optimal price but instead push the temporal slope of the price system toward what a benevolent central planner would want the temporal slope of the price level to be.

Milton Friedman was very clear that economies could either have too much money (Inflation Economics) or too little money (Depression Economics)–and that a central bank was needed to try to hit the sweet spot. He hoped that hitting the sweet spot could be made into a somewhat automatic rule-controlled process, but he was wrong.

So trying to construct a thinking argument that central banks are engaged in something analogous to “price controls” via their monetary policy actions leads even a substantially sub-Turing entity to the conclusion: Sometimes, under conditions of “Inflation Economics”, but not now.

And let me offer all kudos to those like David Beckworth, Scott Sumner, and Jim Pethokoukis who are trying to convince their political allies of these points that I regard as basic and Wicksellian–cutting-edge macro from 125 years ago. But I think that Paul Krugman is right when he believes that they are going to fail. Let me turn the mike over to Paul Krugman to explain why he thinks they are going to fail:

Paul Krugman: More Artificial Unintelligence: “David Beckworth pleads with fellow free-marketeers to stop claiming that…

…low interest rates are “artificial” and comparing them to price controls…. The Fed isn’t imposing a price ceiling… monetary policy… nothing at all like price controls…. What interest rates would be in the absence of distortions and rigidities [is] the Wicksellian natural rate…. The actual interest rate, at zero, is above the natural rate…. But… Beckworth should be asking… why almost nobody on the right is willing to think… not just… ignoramuses like Rand Paul and George Will. The “low interest rates = price controls” meme is bang-your-head-on-the-table stupid–but… John Taylor…. [It’s] a line of argument that people on the right really, really like….

Beckworth is… tak[ing] the… Friedman position… trusting markets… except… [for] the business cycle…. This is… [intellectually] problematic…. You need… market failure to give monetary policy large real effects, and… why… is the only important failure?…

Let me, as an aside, point out that it could indeed be the case that monetary policy joins police, courts, and defense as they only significant areas in which the costs of rent-seeking, regulatory-capture, and other government failures are less than the costs of the market failures that the government could successfully neutralize. It’s unlikely. But it’s possible. Indeed, Milton Friedman thought that that was the case. And he was not at all a dumb man. And laying down general rules sector-by-sector about the relative magnitudes of market and government failures is almost surely a mistake. As John Maynard Keynes wrote in his “The End of Laissez-Faire”:

We cannot therefore settle on abstract grounds, but must handle on its merits in detail what Burke termed: “one of the finest problems in legislation, namely, to determine what the State ought to take upon itself to direct by the public wisdom, and what it ought to leave, with as little interference as possible, to individual exertion…”

But let’s give the mike back to Krugman to make his major point:

More important… this position turns out to be politically unsustainable. “Government is always the problem, not the solution, except when it comes to monetary policy” just doesn’t cut it for modern conservatives. Nor did it cut it for traditional conservatives. Remember, during the 1930s people like Hayek were liquidationists, with Hayek specifically denouncing expansionary monetary policy during a slump as “the creation of artificial demand.” The era of Friedmanism, of free-market views paired with tolerance for monetary stimulus, was a temporary and unsustainable interlude, and no amount of sensible argumentation will bring it back.

But this doesn’t mean that Jim, Scott, David, and company should not try, no? It is not just the Milton Friedman was a galaxy-class expert at playing intellectual Three-Card Monte, no? It is true that at times my breath is still taken away at Friedman’s gall in claiming that a “neutral” and “non-interventionist” monetary policy was one which had the Federal Reserve Bank of New York buying and selling bonds every single day in a frantic attempt to make Say’s Law, false in theory, true in practice. But he wiped the floor with the Hayekians intellectually, culturally, academically, and politically for two generations.

Krugman’s line “claiming that laissez-faire is best for everything save monetary policy (and property rights, and courts, and police, and defense) is intellectually unstable and unsustainable in the long-run” may well be true. But as somebody-or-other once said:

This long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again…


UPDATE: And I should add a link to Krugman’s original:

Paul Krugman: Artificial Unintelligence: “In the early stages of the Lesser Depression…

…those of us who knew a bit about the… 1930s… felt… despair…. People who imagined themselves sophisticated and possessed of deep understanding were resurrecting 75-year-old fallacies and presenting them as deep insights…. [Today] I feel an even deeper sense of despair–because people are still rolling out those same fallacies, even though in the interim those of us who remembered and understood Keynes/Hicks have been right about most things, and those lecturing us have been wrong about everything. So here’s William Cohan in the Times, declaring that the Fed should ‘show some spine’ and raise rates even though there is no sign of accelerating inflation. His reasoning….

The price of borrowing money–interest rates–should be determined by supply and demand, not by manipulation by a market behemoth….

[However,] the Fed sets interest rates, whether it wants to or not–even a supposed hands-off policy has to involve choosing the level of the monetary base somehow…. How would you know if the Fed is setting rates too low? Here’s where Hicks meets Wicksell: rates are too low if the economy is overheating and inflation is accelerating. Not exactly what we’ve seen in the era of zero rates and QE…. There are arguments that the Fed should be willing to abandon its inflation target so as to discourage bubbles. I think those arguments are wrong-but… they have nothing to do with the notion that current rates are somehow artificial, that we should let rates be determined by ‘supply and demand’. The worrying thing is that… crude misunderstandings… are widespread even among people who imagine themselves well-informed and sophisticated. Eighty years of hard economic thinking, and seven years of overwhelming confirmation of that hard thinking, have made no dent in their worldview. Awesome.
