You Say Potato, I Say Potahto; You Say Tomato, I Say Tomahto; You Say Distribution, I Say Expectation

Once again, the estimable Olivier Blanchard is weighing in on the question of inflation, expressing fears about an impending wage-price spiral that cannot be controlled by conventional monetary policy unless the monetary authority is prepared to impose sufficiently tight monetary conditions that would entail substantially higher unemployment than we have experienced since the aftermath of the 2008 financial crisis and Little Depression (aka Great Recession). Several months ago, Blanchard, supporting Larry Summers’s warnings that rising inflation was not likely to be transitory and instead would likely remain high and possibly increase over time, I tried to explain why his fears of high and rising inflation were likely exaggerated. Unpersuaded, he now returns to provide a deeper explanation of his belief that, unless the deep systemic forces that cause inflation are addressed politically rather than left, by default, to be handled by the monetary authority, inflation will remain a persistent and vexing problem.

I’m sorry to say that Professor Blanchard starts off with a massive overstatement. While I don’t discount the possibility — even the reality — that inflation may sometimes be triggered by the attempt of a particular sector of the economy to increase the relative price of the goods or services that it provides, thereby increasing its share of total income at the expense of other sectors, I seriously question whether this is a typical, or even frequent, source of inflation. For example, oil-price increases in the 1970s and wage increases in France after the May 1968 student uprisings did trigger substantial inflation. Inflation served as a method of (1) mitigating ing adverse macroeconomic effects on output and employment and (2) diluting the size of the resulting wealth transfer from other sectors.

Blanchard continues:

2/8. The source of the conflict may be too hot an economy: In the labor market, workers may be in a stronger position to bargain for higher wages given prices. But, in the goods market, firms may also be in a stronger position to increase prices given wages. And, on, it goes.


Again, I’m sorry to say that I find this remark incomprehensible. Blanchard says “the source of the conflict may be too hot an economy,” and in the very next breath says that in the labor market (as if it made sense to view the labor market, accounting for more than half the nominal income of the economy, as a single homogeneous market with stable supply and demand curves), “workers may be in a strong position to bargain for higher wages given prices,” while in the goods market firms may be in a strong position to bargain for higher prices relative to wages. What kind of bargaining position is Blanchard talking about? Is it real, reflecting underlying economic conditions, or is it nominal, reflecting macroeconomic conditions. He doesn’t seem to know. And if he does know, he’s not saying. But he began by saying that the source of the conflict “may be too hot an economy,” suggesting that the source of the conflict is macroeconomic, not a conflict over shares. So I’m confused. We can only follow him a bit further to see what he may be thinking.

3/8. The source of the conflict may be in too high prices of commodities, such as energy. Firms want to increase prices given wages, to reflect the higher cost of intermediate inputs. Workers want to resist the decrease in the real wage, and ask for higher wages. And on it goes.

Now Blanchard seems to be attributing the conflict to an exogenous — and unexmplained — increase in commodity prices. One sector presumably enjoys an improvement in its bargaining position relative to the rest of the economy, thereby being enabled to increase its share of total income. Rather than consider the appropriate response to such an exercise of raw market power, Blanchard simply assumes that, but doesn’t explain how, this increase in share triggers a vicious cycle of compensating increases in the prices and wages of other sectors, rather than a one-off distributional change to reflect a new balance of economic power. This is a complicated story with interesting macroeconomic implications, but Blanchard doesn’t bother to do more than assert that the disturbance sets in motion an ongoing, possibly unlimited, cycle of price and wage increases.

4/8. The state can play various roles. Through fiscal policy, it can slow down the economy and eliminate the overheating. It can subsidize the cost of energy, limiting the decrease in the real wage and the pressure on nominal wages.

5/8. It can finance the subsidies by increasing taxes on some current taxpayers, say exceptional profit taxes, or through deficits and eventual taxes on future taxpayers (who have little say in the process…)

These two statements from the thread are largely innocuous and contribute little or nothing to an understanding of the cause or causes of inflation or of the policies that might mitigate inflation or its effect,

6/8. But, in the end, forcing the players to accept the outcome, and thus stabilizing inflation, is typically left to the central bank. By slowing down the economy, it can force firms to accept lower prices given wages, and workers to accept lower wages given prices.

It’s not clear to me what constitutes “acceptance” of the outcome. Under any circumstance, the players will presumably still seek to choose and execute what, given the situation in which they find themselves, they regard as an optimal plan. Whether the players can execute the plan that they choose will depend on the plans chosen by other players and on the policies adopted by the central bank and other policy makers. If policy makers adopt a consistent set of policies that are feasible and are aligned with the outcomes expected by the players, then the players will likely succeed in implementing what they regard as optimal plans. If the policies that are followed are not consistent and not feasible, then those policies will not be aligned with the outcomes expected by the players. In the latter case, matters will likely get worse not better.

7/8. It is a highly inefficient way to deal with distributional conflicts. One can/should dream of a negotiation between workers, firms, and the state, in which the outcome is achieved without triggering inflation and requiring a painful slowdown.

I can’t help but observe the vagueness associated with the pronoun “it” and its unidentified antecedent. The outcome of a complex economic process cannot be achieved by a negotiation between workers,firms and the state. Things don’t work that way. Whatever negotiation Professor Blanchard is dreaming about, no negotiation can possibly determine the details of an outcome. What is possible is some agreement on policy goals or targets for inflation and some feasible set of policies aimed at achieving, or coming close to, a target rate of inflation. The key variable over which policy makers have some control is total aggregate demand for the economy measured either as a rate of nominal spending and nominal income over a year or as a rate of growth in spending and income compared to the previous year. Since inflation is itself a rate of change, presumaby the relevant target should be a rate of change in total nominal spending and nominal income. Thus, the appropriate target for policy makers to aim for is the yearly rate of growth in total nominal spending and total nominal income.

Given some reasonable expectation about the rate of technical progress (labor productivity) and the rate of increase in the labor force, a target rate of inflation implies a target rate of increase in total nominal spending and total nominal income. Given expectations about the increase in labor productivity, there is an implied rate of increase in nominal wages that is broadly consistent with the inflation target. But that average rate of increase in nominal wages can hardly be expected to be uniform for all industries and all firms and all workers, and it would be folly, on purely technical reasons, to attempt to enforce such a target in average nominal wage growth. And for legal and political reasons, it would be an even greater folly to try to do so.

Besides announcing the underlying basis for the targeted rate of nominal income growth, and encouraging workers and firms to take those targets seriously when negotiating wage contracts and setting prices, while recognizing that deviations from those targets are often reasonable and appropriate in the light of the specific circumstances in which particular firms and industries and labor unions are operating, policy makers have no constructive role to play in the setting of prices or wages for individual firms industries or labor contracts. But providing useful benchmarks for private agents to use as a basis for forming their own expectations about the future to guide their planning for the future is entirely appropriate and useful.

I should acknowledge that, as I have done previously, that the approach to policy making summarized here is based on the analysis developed by Ralph Hawtrey over the course of more than a half century as both a monetary theorist and a policy advisor, and, especially, as Hawtrey explained over a half-century ago in his final book, Incomes and Money.

8/8. But, unfortunately, this requires more trust than can be hoped for and just does not happen. Still, this way of thinking inflation shows what the problem is, and how to think of the least painful solution.

Insofar as policymakers can show that they are coming reasonably close to meeting their announced targets, they will encourage private actors to take those announced targets seriously when forming their own expectations and when negotiating with counterparties on the terms of their economic relationships. The least painful solutions are those in which economic agents align their expectations with the policy targets announced — and achieved — by policy makers.

Welcome to Uneasy Money, aka the Hawtreyblog

UPDATE: I’m re-upping my introductory blog post, which I posted ten years ago toady. It’s been a great run for me, and I hope for many of you, whose interest and responses have motivated to keep it going. So thanks to all of you who have read and responded to my posts. I’m adding a few retrospective comments and making some slight revisions along the way. In addition to new posts, I will be re-upping some of my old posts that still seem to have relevance to the current state of our world.

What the world needs now, with apologies to the great Burt Bachrach and Hal David, is, well, another blog.  But inspired by the great Ralph Hawtrey and the near great Scott Sumner, I decided — just in time for Scott’s return to active blogging — to raise another voice on behalf of a monetary policy actively seeking to promote recovery from what I call the Little Depression, instead of the monetary policy we have now:  waiting for recovery to arrive on its own.  Just like the Great Depression, our Little Depression was caused mainly by overly tight money in an environment of over-indebtedness and financial fragility, and was then allowed to deepen and become entrenched by monetary authorities unwilling to commit themselves to a monetary expansion aimed at raising prices enough to make business expansion profitable.

That was the lesson of the Great Depression.  Unfortunately that lesson, for reasons too complicated to go into now, was never properly understood, because neither Keynesians nor Monetarists had a fully coherent understanding of what happened in the Great Depression.  Although Ralph Hawtrey — called by none other than Keynes “his grandparent in the paths of errancy,” and an early, but unacknowledged, progenitor of Chicago School Monetarism — had such an understanding,  Hawtrey’s contributions were overshadowed and largely ignored, because of often irrelevant and misguided polemics between Keynesians and Monetarists and Austrians.  One of my goals for this blog is to bring to light the many insights of this perhaps most underrated — though competition for that title is pretty stiff — economist of the twentieth century.  I have discussed Hawtrey’s contributions in my book on free banking and in a paper published years ago in Encounter and available here.  Patrick Deutscher has written a biography of Hawtrey.

What deters businesses from expanding output and employment in a depression is lack of demand; they fear that if they do expand, they won’t be able to sell the added output at prices high enough to cover their costs, winding up with redundant workers and having to engage in costly layoffs.  Thus, an expectation of low demand tends to be self-fulfilling.  But so is an expectation of rising prices, because the additional output and employment induced by expectations of rising prices will generate the demand that will validate the initial increase in output and employment, creating a virtuous cycle of rising income, expenditure, output, and employment.

The insight that “the inactivity of all is the cause of the inactivity of each” is hardly new.  It was not the discovery of Keynes or Keynesian economics; it is the 1922 formulation of Frederick Lavington, another great, but underrated, pre-Keynesian economist in the Cambridge tradition, who, in his modesty and self-effacement, would have been shocked and embarrassed to be credited with the slightest originality for that statement.  Indeed, Lavington’s dictum might even be understood as a restatement of Say’s Law, the bugbear of Keynes and object of his most withering scorn.  Keynesian economics skillfully repackaged the well-known and long-accepted idea that when an economy is operating with idle capacity and high unemployment, any increase in output tends to be self-reinforcing and cumulative, just as, on the way down, each reduction in output is self-reinforcing and cumulative.

But at least Keynesians get the point that, in a depression or deep recession, individual incentives may not be enough to induce a healthy expansion of output and employment. Aggregate demand can be too low for an expansion to get started on its own. Even though aggregate demand is nothing but the flip side of aggregate supply (as Say’s Law teaches), if resources are idle for whatever reason, perceived effective demand is deficient, diluting incentives to increase production so much that the potential output expansion does not materialize, because expected prices are too low for businesses to want to expand. But if businesses can be induced to expand output, more than likely, they will sell it, because (as Say’s Law teaches) supply usually does create its own demand.

[Comment after 10 years: In a comment, Rowe asked why I wrote that Say’s Law teaches that supply “usually” creates its own demand. At that time, I responded that I was just using “usually” as a weasel word. But I subsequently realized (and showed in a post last year) that the standard proofs of both Walras’s Law and Say’s Law are defective for economies with incomplete forward and state-contingent markets. We actually know less than we once thought we did!] 

Keynesians mistakenly denied that, by creating price-level expectations consistent with full employment, monetary policy could induce an expansion of output even in a depression. But at least they understood that the private economy can reach an impasse with price-level expectations too low to sustain full employment. Fiscal policy may play a role in remedying a mismatch between expectations and full employment, but fiscal policy can only be as effective as monetary policy allows it to be. Unfortunately, since the downturn of December 2007, monetary policy, except possibly during QE1 and QE2, has consistently erred on the side of uneasiness.

With some unfortunate exceptions, however, few Keynesians have actually argued against monetary easing. Rather, with some honorable exceptions, it has been conservatives who, by condemning a monetary policy designed to provide incentives conducive to business expansion, have helped to hobble a recovery led by the private sector rather than the government which  they profess to want. It is not my habit to attribute ill motives or bad faith to people whom I disagree with. One of the finest compliments ever paid to F. A. Hayek was by Joseph Schumpeter in his review of The Road to Serfdom who chided Hayek for “politeness to a fault in hardly ever attributing to his opponents anything but intellectual error.” But it is a challenge to come up with a plausible explanation for right-wing opposition to monetary easing.

[Comment after 10 years: By 2011 when this post was written, right-wing bad faith had already become too obvious to ignore, but who could then have imagined where the willingness to resort to bad faith arguments without the slightest trace of compunction would lead them and lead us.] 

In condemning monetary easing, right-wing opponents claim to be following the good old conservative tradition of supporting sound money and resisting the inflationary proclivities of Democrats and liberals. But how can claims of principled opposition to inflation be taken seriously when inflation, by every measure, is at its lowest ebb since the 1950s and early 1960s? With prices today barely higher than they were three years ago before the crash, scare talk about currency debasement and future hyperinflation reminds me of Ralph Hawtrey’s famous remark that warnings that leaving the gold standard during the Great Depression would cause runaway inflation were like crying “fire, fire” in Noah’s flood.

The groundlessness of right-wing opposition to monetary easing becomes even plainer when one recalls the attacks on Paul Volcker during the first Reagan administration. In that episode President Reagan and Volcker, previously appointed by Jimmy Carter to replace the feckless G. William Miller as Fed Chairman, agreed to make bringing double-digit inflation under control their top priority, whatever the short-term economic and political costs. Reagan, indeed, courageously endured a sharp decline in popularity before the first signs of a recovery became visible late in the summer of 1982, too late to save Reagan and the Republicans from a drubbing in the mid-term elections, despite the drop in inflation to 3-4 percent. By early 1983, with recovery was in full swing, the Fed, having abandoned its earlier attempt to impose strict Monetarist controls on monetary expansion, allowed the monetary aggregates to grow at unusually rapid rates.

However, in 1984 (a Presidential election year) after several consecutive quarters of GDP growth at annual rates above 7 percent, the Fed, fearing a resurgence of inflation, began limiting the rate of growth in the monetary aggregates. Reagan’s secretary of the Treasury, Donald Regan, as well as a variety of outside Administration supporters like Arthur Laffer, Larry Kudlow, and the editorial page of the Wall Street Journal, began to complain bitterly that the Fed, in its preoccupation with fighting inflation, was deliberately sabotaging the recovery. The argument against the Fed’s tightening of monetary policy in 1984 was not without merit. But regardless of the wisdom of the Fed tightening in 1984 (when inflation was significantly higher than it is now), holding up the 1983-84 Reagan recovery as the model for us to follow now, while excoriating Obama and Bernanke for driving inflation all the way up to 1 percent, supposedly leading to currency debauchment and hyperinflation, is just a bit rich. What, I wonder, would Hawtrey have said about that?

In my next posting I will look a little more closely at some recent comparisons between the current non-recovery and recoveries from previous recessions, especially that of 1983-84.

The Real-Bills Doctrine, the Lender of Last Resort, and the Scope of Banking

Here is another section from my work in progress on the Smithian and Humean traditions in monetary economics. The discussion starts with a comparison of the negative view David Hume took toward banks and the positive view taken by Adam Smith which was also discussed in the previous post on the price-specie-flow mechanism. This section discusses how Smith, despite viewing banks positively, also understood that banks can be a source of disturbances as well as of efficiencies, and how he addressed that problem and how his followers who shared a positive view toward banks addressed the problem. Comments and feedback are welcome and greatly appreciated.

Hume and Smith had very different views about fractional-reserve banking and its capacity to provide the public with the desired quantity of money (banknotes and deposits) and promote international adjustment. The cash created by banks consists of liabilities on themselves that they exchange for liabilities on the public. Liabilities on the public accepted by banks become their assets, generating revenue streams with which banks cover their outlays including obligations to creditors and stockholders.

The previous post focused on the liability side of bank balance sheets, and whether there are economic forces that limit the size of those balance sheets, implying a point of equilibrium bank expansion. Believing that banks have an unlimited incentive to issue liabilities, whose face value exceeds their cost of production, Hume considered banks dangerous and inflationary. Smith disagreed, arguing that although bank money is a less costly alternative to the full-bodied money preferred by Hume, banks don’t create liabilities limitlessly, because, unless those liabilities generate corresponding revenue streams, they will be unable to redeem those liabilities, which their creditors may require of them, at will. To enhance the attractiveness of those liabilities and to increase the demand to hold them, competitive banks promise to convert those liabilities, at a stipulated rate, into an asset whose value they do not control. Under those conditions, banks have neither the incentive nor the capacity to cause inflation.

I turn now to a different topic: whether Smith’s rejection of the idea that banks are systematically biased toward overissuing liabilities implies that banks require no external control or intervention. I begin by briefly referring to Smith’s support of the real-bills doctrine and then extend that discussion to two other issues: the lender of last resort and the scope of banking.

A         Real-Bills Doctrine

I have argued elsewhere that, besides sketching the outlines of Fullarton’s argument for the Law of Reflux, Adam Smith recommended that banks observe a form of the real-bills doctrine, namely that banks issue sight liabilities only in exchange for real commercial bills of short (usually 90-days) duration. Increases in the demand for money cause bank balance sheets to expand; decreases cause them to contract. Unlike Mints (1945), who identified the Law of Reflux with the real-bills doctrine, I suggested that Smith viewed the real-bills doctrine as a pragmatic policy to facilitate contractions in the size of bank balance sheets as required by the reflux of their liabilities. With the discrepancy between the duration of liabilities and assets limited by issuing sight liabilities only in exchange for short-term bills, bank balance sheets would contract automatically thereby obviating, at least in part, the liquidation of longer-term assets at depressed prices.

On this reading, Smith recognized that banking policy ought to take account of the composition of bank balance sheets, in particular, the sort of assets that banks accept as backing for the sight liabilities that they issue. I would also emphasize that on this interpretation, Smith did not believe, as did many later advocates of the doctrine, that lending on the security of real bills is sufficient to prevent the price level from changing. Even if banks have no systematic incentive to overissue their liabilities, unless those liabilities are made convertible into an asset whose value is determined independently of the banks, the value of their liabilities is undetermined. Convertibility is how banks anchor the value of their liabilities, thereby increasing the attractiveness of those liabilities to the public and the willingness of the public to accept and hold them.

But Smith’s support for the real-bills doctrine indicates that, while understanding the equilibrating tendencies of competition on bank operations, he also recognized the inherent instability of banking caused by fluctuations in the value and liquidity of their assets. Smith’s support for the real-bills doctrine addressed one type of instability: the maturity mismatch between banks’ assets and liabilities. But there are other sources of instability, which may require further institutional or policy measures beyond the general laws of property and contract whose application and enforcement, in Smith’s view, generally sufficed for the self-interested conduct of private firms to lead to socially benign outcomes.

In the remainder of this section, I consider two other methods of addressing the vulnerability of bank assets to sudden losses of value: (1) the creation or empowerment of a lender of last resort capable of lending to illiquid, but solvent, banks possessing good security (valuable assets) as collateral against which to borrow, and (2) limits beyond the real-bills doctrine over the permissible activities undertaken by commercial banks.

B         Lender of Last Resort

Although the real-bills doctrine limits the exposure of bank balance sheets to adverse shocks on the value of long-term liabilities, even banks whose liabilities were issued in exchange for short-term real bills of exchange may be unable to meet all demands for redemption in periods of extreme financial distress, when debtors cannot sell their products at the prices they expected and cannot meet their own obligations to their creditors. If banks are called upon to redeem their liabilities, banks may be faced with a choice between depleting their own cash reserves, when they are most needed, or liquidating other assets at substantial, if not catastrophic, losses.

Smith’s version of the real-bills doctrine addressed one aspect of balance-sheet risk, but the underlying problem is deeper and more complicated than the liquidity issue that concerned Smith. The assets accepted by banks in exchange for their liabilities are typically not easily marketable, so if those assets must be shed quickly to satisfy demands for payment, banks’ solvency may be jeopardized by consequent capital losses. Limiting portfolios to short-term assets limits exposure to such losses, but only when the disturbances requiring asset liquidation affect only a relatively small number of banks. As the number of affected banks increases, their ability to counter the disturbance is impaired, as the interbank market for credit starts to freeze up or break down entirely, leaving them unable to offer short-term relief to, or receive it from, other momentarily illiquid banks. It is then that emergency lending by a lender of last resort to illiquid, but possibly still solvent, banks is necessary.

What causes a cluster of expectational errors by banks in exchanging their liabilities for assets supplied by their customers that become less valuable than they were upon acceptance? Are financial crises that result in, or are caused by, asset write downs by banks caused by random clusters of errors by banks, or are there systematic causes of such errors? Does the danger lie in the magnitude of the errors or in the transmission mechanism?

Here, too, the Humean and Smithian traditions seem to be at odds, offering different answers to problems, or, if not answers, at least different approaches to problems. Focusing on the liability side of bank balance sheets, the Humean tradition emphasizes the expansion of bank lending and the consequent creation of banknotes or deposits as the main impulse to macroeconomic fluctuations, a boom-bust or credit cycle triggered by banks’ lending to finance either business investment or consumer spending. Despite their theoretical differences, both Austrian business-cycle theory and Friedmanite Monetarism share a common intellectual ancestry, traceable by way of the Currency School to Hume, identifying the source of business-cycle fluctuations in excessive growth in the quantity of money.

The eclectic Smithian tradition accommodates both monetary and non-monetary business-cycle theories, but balance-sheet effects on banks are more naturally accommodated within the Smithian tradition than the Humean tradition with its focus on the liabilities not the assets of banks. At any rate, more research is necessary before we can decide whether serious financial disturbances result from big expectational errors or from contagion effects.

The Great Depression resulted from a big error. After the steep deflation and depression of 1920-22, followed by a gradual restoration of the gold standard, fears of further deflation were dispelled and steady economic expansion, especially in the United States, resulted. Suddenly in 1929, as France and other countries rejoined the gold standard, the fears voiced by Hawtrey and Cassel that restoring the gold standard could have serious deflationary consequences appeared increasingly more likely to be realized. Real signs of deflation began to appear in the summer of 1929, and in the fall the stock market collapsed. Rather than use monetary policy to counter incipient deflation, policy makers and many economists argued that deflation was part of the solution not the problem. And the Depression came.

It is generally agreed that the 2008 financial crisis that triggered the Little Depression (aka Great Recession) was largely the result of a housing bubble fueled by unsound mortgage lending by banks and questionable underwriting practices in packaging and marketing of mortgage-backed securities. However, although the housing bubble seems to have burst the spring of 2007, the crisis did not start until September 2008.

It is at least possible, as I have argued (Glasner 2018) that, despite the financial fragility caused by the housing bubble and unsound lending practices that fueled the bubble, the crisis could have been avoided but for a reflexive policy tightening by the Federal Reserve starting in 2007 that caused a recession starting in December 2007 and gradually worsening through the summer of 2008. Rather than ease monetary policy as the recession deepened, the Fed, distracted by rising headline inflation owing to rising oil prices that summer, would not reduce its interest-rate target further after March 2008. If my interpretation is correct, the financial crisis of 2008 and the subsequent Little Depression (aka Great Recession) were as much caused by bad monetary policy as by the unsound lending practices and mistaken expectations by lenders.

It is when all agents are cash constrained that a lender of last resort that is able to provide the liquidity that the usual suppliers of liquidity cannot provide, but are instead demanding, is necessary to avoid a systemic breakdown. In 2008, the Fed was unwilling to satisfy demands for liquidity until the crisis had deteriorated to the point of a worldwide collapse. In the nineteenth century, Thornton and Fullarton understood that the Bank of England was uniquely able to provide liquidity in such circumstances, recommending that it lend freely in periods of financial stress.

That policy was not viewed favorably either by Humean supporters of the Currency Principle, opposed to all forms of fractional-reserve banking, or by Smithian supporters of free banking who deplored the privileged central-banking position granted to the Bank of England. Although the Fed in 2008 acknowledged that it was both a national and international lender of last resort, it was tragically slow to take the necessary actions to end the crisis after allowing it to spiral nearly out of control.

While cogent arguments have been made that a free-banking alternative to the lender-of-last-resort services of the Bank of England might have been possible in the nineteenth century,[2] even a free-banking system would require a mechanism for handling periods of financial stress. Free-banking supporters argue that bank clearinghouses have emerged spontaneously in the absence of central banks, and could provide the lender-of-last resort services provided by central banks. But, insofar as bank clearinghouses would take on the lender-of-last-resort function, which involves some intervention and supervision of bank activities by either the clearinghouse or the central bank, the same anticompetitive or cartelistic objections to the provision of lender-of-last-resort services by central banks also would apply to the provision of those services by clearinghouses. So, the tension between libertarian, free-market principles and lender-of-last-resort services would not necessarily be eliminated bank clearinghouses instead of central banks provided those services.

This is an appropriate place to consider Walter Bagehot’s contribution to the lender-of-last-resort doctrine. Building on the work of Thornton and Fullarton, Bagehot formulated the classic principle that, during times of financial distress, the Bank of England should lend freely at a penalty rate to banks on good security. Bagehot, himself, admitted to a certain unease in offering this advice, opining that it was regrettable that the Bank of England achieved a pre-eminent position in the British banking system, so that a decentralized banking system, along the lines of the Scottish free-banking system, could have evolved. But given the historical development of British banking, including the 1844 Bank Charter Act, Bagehot, an eminently practical man, had no desire to recommend radical reform, only to help the existing system operate as smoothly as it could be made to operate.

But the soundness of Bagehot’s advice to lend freely at a penalty rate is dubious. In a financial crisis, the market rate of interest primarily reflects a liquidity premium not an expected real return on capital, the latter typically being depressed in a crisis. Charging a penalty rate to distressed borrowers in a crisis only raises the liquidity premium. Monetary policy ought to aim to reduce, not to increase, that premium. So Bagehot’s advice, derived from a misplaced sense of what is practical and prudent and financially sound, rather than from sound analysis, was far from sound.

Under the gold standard, or under any fixed-exchange-rate regime, a single country has an incentive to raise interest rates above the rates of other countries to prevent a gold outflow or attract an inflow. Under these circumstances, a failure of international cooperation can lead to competitive rate increases as monetary authorities scramble to maintain or increase their gold reserves. In testimony to the Macmillan Commission in 1930, Ralph Hawtrey masterfully described the obligation of a central bank in a crisis. Here is his exchange with the Chairman of the Commission Hugh Macmillan:

MACMILLAN: Suppose . . . without restricting credit . . . that gold had gone out to a very considerable extent, would that not have had very serious consequences on the international position of London?

HAWTREY: I do not think the credit of London depends on any particular figure of gold holding. . . . The harm began to be done in March and April of 1925 [when] the fall in American prices started. There was no reason why the Bank of England should have taken ny action at that time so far as the question of loss of gold is concerned. . . . I believed at the time and I still think that the right treatment would have been to restore the gold standard de facto before it was restored de jure. That is what all the other countries have done. . . . I would have suggested that we should have adopted the practice of always selling gold to a sufficient extent to prevent the exchange depreciating. There would have been no legal obligation to continue convertibility into gold . . . If that course had been adopted, the Bank of England would never have been anxious about the gold holding, they would have been able to see it ebb away to quite a considerable extent with perfect equanimity, . . and might have continued with a 4 percent Bank Rate.

MACMILLAN: . . . the course you suggest would not have been consistent with what one may call orthodox Central Banking, would it?

HAWTREY: I do not know what orthodox Central Banking is.

MACMILLAN: . . . when gold ebbs away you must restrict credit as a general principle?

HAWTREY: . . . that kind of orthodoxy is like conventions at bridge; you have to break them when the circumstances call for it. I think that a gold reserve exists to be used. . . . Perhaps once in a century the time comes when you can use your gold reserve for the governing purpose, provided you have the courage to use practically all of it.

Hawtrey here was echoing Fullarton’s insight that there is no rigid relationship between the gold reserves held by the Bank of England and the total quantity of sight liabilities created by the British banking system. Rather, he argued, the Bank should hold an ample reserve sufficient to satisfy the demand for gold in a crisis when a sudden and temporary demand for gold had to be accommodated. That was Hawtrey’s advice, but not Bagehot’s, whose concern was about banks’ moral hazard and imprudent lending in the expectation of being rescued in a crisis by the Bank of England. Indeed, moral hazard is a problem, but in a crisis it is a secondary problem, when, as Hawtrey explained, alleviating the crisis, not discouraging moral hazard, must be the primary concern of the lender of last resort.

            C         Scope of Banking

Inclined to find remedies for financial distress in structural reforms limiting the types of assets banks accept in exchange for their sight liabilities, Smith did not recommend a lender of last resort.[3] Another method of reducing risk, perhaps more in tune with the Smithian real-bills doctrine than a lender of last resort, is to restrict the activities of banks that issue banknotes and deposits.

In Anglophone countries, commercial banking generally evolved as separate and distinct from investment banking. It was only during the Great Depression and the resulting wave of bank failures that the combination of commercial and investment banking was legally prohibited by the Glass-Steagall Act, eventually repealed in 1999. On the Continent, where commercial banking penetrated less deeply into the fabric of economic and commercial life than in Anglophone countries, commercial banking developed more or less along with investment banking in what are called universal banks.

Whether the earlier, and more widespread, adoption of commercial banking in Anglophone countries than on the Continent advanced the idea that no banking institution should provide both commercial- and investment-banking services is not a question about which I offer a conjecture, but it seems a topic worthy of study. The Glass-Steagall Act, which enforced that separation after being breached early in the twentieth century, a breach thought by some to have contributed to US bank failures in the Great Depression, was based on a presumption against combining and investment-banking in a single institution. But even apart from the concerns that led to enactment of Glass-Steagall, limiting the exposure of commercial banks, which supply most of the cash held by the public, to the balance-sheet risk associated with investment-banking activities seems reasonable. Moreover, the adoption of government deposit insurance after the Great Depression as well as banks’ access to the discount window of the central bank may augment the moral hazard induced by deposit insurance and a lender of last resort, offsetting potential economies of scope associated with combining commercial and investment banking.

Although legal barriers to the combination of commercial and investment banking have long been eliminated, proposals for “narrow banking” that would restrict the activities undertaken by commercial banks continue to be made. Two different interpretations of narrow banking – one Smithian and one Humean – are possible.

The Humean concern about banking was that banks are inherently disposed to overissue their liabilities. The Humean response to the concern has been to propose 100-percent reserve banking, a comprehensive extension of the 100-percent marginal reserve requirement on the issue of banknotes imposed by the Bank Charter Act. Such measures could succeed, as some supporters (Simons 1936) came to realize, only if accompanied by a radical change the financial practices and arrangements on which all debt contracts are based. It is difficult to imagine that the necessary restructuring of economic activity would ever be implemented or tolerated.

The Humean concern was dismissed by the Smithian tradition, recognizing that banks, even if unconstrained by reserve requirements, have no incentive to issue liabilities without limit. The Smithian concern was whether banks could cope with balance-sheet risks after unexpected losses in the value of their assets. Although narrow banking proposals are a legitimate and possibly worthwhile response to that concern, the acceptance by central banks of responsibility to act as a lender of last resort and widespread government deposit insurance to dampen contagion effects have taken the question of narrowing or restricting the functions of money-creating banks off the table. Whether a different strategy for addressing the systemic risks associated with banks’ creation of money by relying solely on deposit insurance and a lender of last resort is a question that still deserves thoughtful attention.

Larry Summers v. John Taylor: No Contest

It seems that an announcement about who will be appointed as Fed Chairman after Janet Yellen’s terms expires early next year is imminent. Although there are sources in the Administration, e.g., the President, indicating that Janet Yellen may be reappointed, the betting odds strongly favor Jerome Powell, a Republican currently serving as a member of the Board of Governors, over the better-known contender, John Taylor, who has earned a considerable reputation as an academic economist, largely as author of the so-called Taylor Rule, and has also served as a member of the Council of Economic Advisers and the Treasury in previous Republican administrations.

Taylor’s support seems to be drawn from the more militant ideological factions within the Republican Party owing to his past criticism of Fed’s quantitative-easing policy after the financial crisis and little depression, having famously predicted that quantitative easing would revive dormant inflationary pressures, presaging a return to the stagflation of the 1970s, while Powell, who has supported the Fed’s policies under Bernanke and Yellen, is widely suspect in the eyes of the Republican base as a just another elitist establishmentarian inhabiting the swamp that the new administration was elected to drain. Nevertheless, Taylor’s academic background, his prior government service, and his long-standing ties to the US and international banking and financial institutions make him a less than ideal torch bearer for the true-blue (or true-red) swamp drainers whose ostensible goal is less to take control of the Fed than to abolish it. To accommodate both the base and the establishment, it is possible that, as reported by Breitbart, both Powell and Taylor will be appointed, one replacing Yellen as chairman, the other replacing Stanley Fischer as vice-chairman.

Seeing no evidence that Taylor has a sufficient following for his appointment to provide any political benefit, I have little doubt that it will be Powell who replaces Yellen, possibly along with Taylor as Vice-Chairman, if Taylor, at the age of 71, is willing to accept a big pay cut, just to take the vice-chairmanship with little prospect of eventually gaining the top spot he has long coveted.

Although I think it unlikely that Taylor will be the next Fed Chairman, the recent flurry of speculation about his possible appointment prompted me to look at a recent talk that he gave at the Federal Reserve Bank of Boston Conference on the subject: Are Rules Made to be Broken? Discretion and Monetary Policy. The title of his talk “Rules versus Discretion: Assessing the Debate over Monetary Policy” is typical of Taylor’s very low-key style, a style that, to his credit, is certainly not calculated to curry favor with the Fed-bashers who make up a large share of a Republican base that demands constant attention and large and frequently dispensed servings of red meat.

I found several things in Taylor’s talk notable. First, and again to his credit, Taylor does, on occasion, acknowledge the possibility that other interpretations of events from his own are possible. Thus, in arguing that the good macroeconomic performance (“the Great Moderation”) from about 1985 to 2003, was the result of the widespread adoption of “rules-based” monetary policy, and that the subsequent financial crisis and deep recession were the results of the FOMC’s having shifted, after the 2001 recession, from that rules-based policy to a discretionary policy, by keeping interest rates too low for too long, Taylor did at least recognize the possibility that the reason that the path of interest rates after 2003 departed from the path that, he claims, had been followed during the Great Moderation was that the economy was entering a period of inherently greater instability in the early 2000s than in the previous two decades because of external conditions unrelated to actions taken by the Fed.

The other view is that the onset of poor economic performance was not caused by a deviation from policy rules that were working, but rather to other factors. For example, Carney (2013) argues that the deterioration of performance in recent years occurred because “… the disruptive potential of financial instability—absent effective macroprudential policies—leads to a less favourable Taylor frontier.” Carney (2013) illustrated his argument with a shift in the tradeoff frontier as did King (2012). The view I offer here is that the deterioration was due more to a move off the efficient policy frontier due to a change in policy. That would suggest moving back toward the type of policy rule that described policy decisions during the Great Moderation period. (p. 9)

But despite acknowledging the possibility of another view, Taylor offers not a single argument against it. He merely reiterates his own unsupported opinion that the policy post-2003 became less rule-based than it had been from 1985 to 2003. However, later in his talk in a different context, Taylor does return to the argument that the Fed’s policy after 2003 was not fundamentally different from its policy before 2003. Here Taylor is assuming that Bernanke is acknowledging that there was a shift in from the rules-based monetary policy of 1985 to 2003, but that the post-2003 monetary policy, though not rule-based as in the way that it had been in 1985 to 2003, was rule-based in a different sense. I don’t believe that Bernanke would accept that there was a fundamental change in the nature of monetary policy after 2003, but that is not really my concern here.

At a recent Brookings conference, Ben Bernanke argued that the Fed had been following a policy rule—including in the “too low for too long” period. But the rule that Bernanke had in mind is not a rule in the sense that I have used it in this discussion, or that many others have used it.

Rather it is a concept that all you really need for effective policy making is a goal, such as an inflation target and an employment target. In medicine, it would be the goal of a healthy patient. The rest of policymaking is doing whatever you as an expert, or you as an expert with models, thinks needs to be done with the instruments. You do not need to articulate or describe a strategy, a decision rule, or a contingency plan for the instruments. If you want to hold the interest rate well below the rule-based strategy that worked well during the Great Moderation, as the Fed did in 2003-2005, then it’s ok, if you can justify it in terms of the goal.

Bernanke and others have argued that this approach is a form of “constrained discretion.” It is an appealing term, and it may be constraining discretion in some sense, but it is not inducing or encouraging a rule as the language would have you believe. Simply having a specific numerical goal or objective function is not a rule for the instruments of policy; it is not a strategy; in my view, it ends up being all tactics. I think there is evidence that relying solely on constrained discretion has not worked for monetary policy. (pp. 16-17)

Taylor has made this argument against constrained discretion before in an op-ed in the Wall Street Journal (May 2, 2015). Responding to that argument I wrote a post (“Cluelessness about Strategy, Tactics and Discretion”) which I think exposed how thoroughly confused Taylor is about what a monetary rule can accomplish and what the difference is between a monetary rule that specifies targets for an instrument and a monetary rule that specifies targets for policy goals. At an even deeper level, I believe I also showed that Taylor doesn’t understand the difference between strategy and tactics or the meaning of discretion. Here is an excerpt from my post of almost two and a half years ago.

Taylor denies that his steady refrain calling for a “rules-based policy” (i.e., the implementation of some version of his beloved Taylor Rule) is intended “to chain the Fed to an algebraic formula;” he just thinks that the Fed needs “an explicit strategy for setting the instruments” of monetary policy. Now I agree that one ought not to set a policy goal without a strategy for achieving the goal, but Taylor is saying that he wants to go far beyond a strategy for achieving a policy goal; he wants a strategy for setting instruments of monetary policy, which seems like an obvious confusion between strategy and tactics, ends and means.

Instruments are the means by which a policy is implemented. Setting a policy goal can be considered a strategic decision; setting a policy instrument a tactical decision. But Taylor is saying that the Fed should have a strategy for setting the instruments with which it implements its strategic policy.  (OED, “instrument – 1. A thing used in or for performing an action: a means. . . . 5. A tool, an implement, esp. one used for delicate or scientific work.”) This is very confused.

Let’s be very specific. The Fed, for better or for worse – I think for worse — has made a strategic decision to set a 2% inflation target. Taylor does not say whether he supports the 2% target; his criticism is that the Fed is not setting the instrument – the Fed Funds rate – that it uses to hit the 2% target in accordance with the Taylor rule. He regards the failure to set the Fed Funds rate in accordance with the Taylor rule as a departure from a rules-based policy. But the Fed has continually undershot its 2% inflation target for the past three [now almost six] years. So the question naturally arises: if the Fed had raised the Fed Funds rate to the level prescribed by the Taylor rule, would the Fed have succeeded in hitting its inflation target? If Taylor thinks that a higher Fed Funds rate than has prevailed since 2012 would have led to higher inflation than we experienced, then there is something very wrong with the Taylor rule, because, under the Taylor rule, the Fed Funds rate is positively related to the difference between the actual inflation rate and the target rate. If a Fed Funds rate higher than the rate set for the past three years would have led, as the Taylor rule implies, to lower inflation than we experienced, following the Taylor rule would have meant disregarding the Fed’s own inflation target. How is that consistent with a rules-based policy?

This is such an obvious point – and I am hardly the only one to have made it – that Taylor’s continuing failure to respond to it is simply inexcusable. In his apologetics for the Taylor rule and for legislation introduced (no doubt with his blessing and active assistance) by various Republican critics of Fed policy in the House of Representatives, Taylor repeatedly insists that the point of the legislation is just to require the Fed to state a rule that it will follow in setting its instrument with no requirement that Fed actually abide by its stated rule. The purpose of the legislation is not to obligate the Fed to follow the rule, but to merely to require the Fed, when deviating from its own stated rule, to provide Congress with a rationale for such a deviation. I don’t endorse the legislation that Taylor supports, but I do agree that it would be desirable for the Fed to be more forthcoming than it has been in explaining the reasoning about its monetary-policy decisions, which tend to be either platitudinous or obfuscatory rather than informative. But if Taylor wants the Fed to be more candid and transparent in defending its own decisions about monetary policy, it would be only fitting and proper for Taylor, as an aspiring Fed Chairman, to be more forthcoming than he has yet been about the obvious, and rather scary, implications of following the Taylor Rule during the period since 2003.

If Taylor is nominated to be Chairman or Vice-Chairman of the Fed, I hope that, during his confirmation hearings, he will be asked to explain what the implications of following the Taylor Rule would have been in the post-2003 period.

As the attached figure shows PCE inflation (excluding food and energy prices) was 1.9 percent in 2004. If inflation in 2004 was less than the 2% inflation target assumed by the Taylor Rule, why does Taylor think that raising interest rates in 2004 would have been appropriate? And if inflation in 2005 was merely 2.2%, just barely above the 2% target, what rate should the Fed Funds rate have reached in 2005, and how would that rate have affected the fairly weak recovery from the 2001 recession? And what is the basis for Taylor’s assessment that raising the Fed Funds rate in 2005 to a higher level than it was raised to would have prevented the subsequent financial crisis?

Taylor’s implicit argument is that by not raising interest rates as rapidly as the Taylor rule required, the Fed created additional uncertainty that was damaging to the economy. But what was the nature of the uncertainty created? The Federal Funds rate is merely the instrument of policy, not the goal of policy. To argue that the Fed was creating additional uncertainty by not changing its interest rate in line with the Taylor rule would only make sense if the economic agents care about how the instrument is set, but if it is an instrument the importance of the Fed Funds rate is derived entirely from its usefulness in achieving the policy goal of the Fed and the policy goal was the 2% inflation rate, which the Fed came extremely close to hitting in the 2004-06 period, during which Taylor alleges that the Fed’s monetary policy went off the rails and became random, unpredictable and chaotic.

If you calculate the absolute difference between the observed yearly PCE inflation rate (excluding food and energy prices) and the 2% target from 1985 to 2003 (Taylor’s golden age of monetary policy) the average yearly deviation was 0.932%. From 2004 to 2015, the period of chaotic monetary policy in Taylor’s view, the average yearly deviation between PCE inflation and the 2% target was just 0.375%. So when was monetary policy more predictable? Even if you just look at the last 12 years of the golden age (1992 to 2003), the average annual deviation was 0.425%.

The name Larry Summers is in the title of this post, but I haven’t mentioned him yet, so let me explain where Larry Summers comes into the picture. In his talk, Taylor mentions a debate about rules versus discretion that he and Summers had at the 2013 American Economic Association meetings and proceeds to give the following account of the key interchange in that debate.

Summers started off by saying: “John Taylor and I have, it will not surprise you . . . a fundamental philosophical difference, and I would put it in this way. I think about my doctor. Which would I prefer: for my doctor’s advice, to be consistently predictable, or for my doctor’s advice to be responsive to the medical condition with which I present? Me, I’d rather have a doctor who most of the time didn’t tell me to take some stuff, and every once in a while said I needed to ingest some stuff into my body in response to the particular problem that I had. That would be a doctor who’s [sic] [advice], believe me, would be less predictable.” Thus, Summers argues in favor of relying on an all-knowing expert, a doctor who does not perceive the need for, and does not use, a set of guidelines, but who once in a while in an unpredictable way says to ingest some stuff. But as in economics, there has been progress in medicine over the years. And much progress has been due to doctors using checklists, as described by Atul Gawande.

Of course, doctors need to exercise judgement in implementing checklists, but if they start winging it or skipping steps the patients usually suffer. Experience and empirical studies show that checklist-free medicine is wrought with dangers just as rules-free, strategy-free monetary policy is. (pp. 15-16)

Taylor’s citation of Atul Gawande, author of The Checklist Manifesto, is pure obfuscation. To see how off-point it is, have a look at this review published in the Seattle Times.

“The Checklist Manifesto” is about how to prevent highly trained, specialized workers from making dumb mistakes. Gawande — who appears in Seattle several times early next week — is a surgeon, and much of his book is about surgery. But he also talks to a construction manager, a master chef, a venture capitalist and the man at The Boeing Co. who writes checklists for airline pilots.

Commercial pilots have been using checklists for decades. Gawande traces this back to a fly-off at Wright Field, Ohio, in 1935, when the Army Air Force was choosing its new bomber. Boeing’s entry, the B-17, would later be built by the thousands, but on that first flight it took off, stalled, crashed and burned. The new airplane was complicated, and the pilot, who was highly experienced, had forgotten a routine step.

For pilots, checklists are part of the culture. For surgical teams they have not been. That began to change when a colleague of Gawande’s tried using a checklist to reduce infections when using a central venous catheter, a tube to deliver drugs to the bloodstream.

The original checklist: wash hands; clean patient’s skin with antiseptic; use sterile drapes; wear sterile mask, hat, gown and gloves; use a sterile dressing after inserting the line. These are all things every surgical team knows. After putting them in a checklist, the number of central-line infections in that hospital fell dramatically.

Then came the big study, the use of a surgical checklist in eight hospitals around the world. One was in rural Tanzania, in Africa. One was in the Kingdom of Jordan. One was the University of Washington Medical Center in Seattle. They were hugely different hospitals with much different rates of infection.

Use of the checklist lowered infection rates significantly in all of them.

Gawande describes the key things about a checklist, much of it learned from Boeing. It has to be short, limited to critical steps only. Generally the checking is not done by the top person. In the cockpit, the checklist is read by the copilot; in an operating room, Gawande discovered, it is done best by a nurse.

Gawande wondered whether surgeons would accept control by a subordinate. Which was stronger, the culture of hierarchy or the culture of precision? He found reason for optimism in the following dialogue he heard in the hospital in Amman, Jordan, after a nurse saw a surgeon touch a nonsterile surface:

Nurse: “You have to change your glove.”

Surgeon: “It’s fine.”

Nurse: “No, it’s not. Don’t be stupid.”

In other words, the basic rule underlying the checklist is simply: don’t be stupid. It has nothing to do with whether doctors should exercise judgment, or “winging it,” or “skipping steps.” What was Taylor even thinking? For a monetary authority not to follow a Taylor rule is not analogous to a doctor practicing checklist-free medicine.

As it happens, I have a story of my own about whether following numerical rules without exercising independent judgment makes sense in practicing medicine. Fourteen years ago, on the Friday before Labor Day, I was exercising at home and began to feeling chest pains. After ignoring the pain for a few minutes, I stopped and took a shower and then told my wife that I thought I needed to go to the hospital, because I was feeling chest pains – I was still in semi-denial about what I was feeling – my wife asked me if she should call 911, and I said that that might be a good idea. So she called 911, and told the operator that I was feeling chest pains. Within a couple of minutes, two ambulances arrived, and I was given an aspirin to chew and a nitroglycerine tablet to put under my tongue. I was taken to the emergency room at the hospital nearest to my home. After calling 911, my wife also called our family doctor to let him know what was happening and which hospital I was being taken to. He then placed a call to a cardiologist who had privileges at that hospital who happened to be making rounds there that morning.

When I got to the hospital, I was given an electrocardiogram, and my blood was taken. I was also asked to rate my pain level on a scale of zero to ten. The aspirin and nitroglycerine had reduced the pain level slightly, but I probably said it was at eight or nine. However, the ER doc looked at the electrocardiogram results and the enzyme levels in my blood, and told me that there was no indication that I was having a heart attack, but that they would keep me in the ER for observation. Luckily, the cardiologist who had been called by my internist came to the ER, and after talking to the ER doc, looking at the test results, came over to me and started asking me questions about what had happened and how I was feeling. Although the test results did not indicate that I was having heart attack, the cardiologist quickly concluded that what I was experiencing likely was a heart attack. He, therefore, hinted to me that I should request to be transferred to another nearby hospital, which not only had a cath lab, as the one I was then at did, but also had an operating room in which open heart surgery could be performed, if that would be necessary. It took a couple of tries on his part before I caught on to what he was hinting at, but as soon as I requested to be transferred to the other hospital, he got me onto an ambulance ASAP so that he could meet me at the hospital and perform an angiogram in the cath lab, cancelling an already scheduled angiogram.

The angiogram showed that my left anterior descending artery was completely blocked, so open-heart surgery was not necessary; angioplasty would be sufficient to clear the artery, which the cardiologist performed, also implanting two stents to prevent future blockage.  I remained in the cardiac ICU for two days, and was back home on Monday, when my rehab started. I was back at work two weeks later.

The willingness of my cardiologist to use his judgment, experience and intuition to ignore the test results indicating that I was not having a heart attack saved my life. If the ER doctor, following the test results, had kept me in the ER for observation, I would have been dead within a few hours. Following the test results and ignoring what the patient was feeling would have been stupid. Luckily, I was saved by a really good cardiologist. He was not stupid; he could tell that the numbers were not telling the real story about what was happening to me.

We now know that, in the summer of 2008, the FOMC, being in the thrall of headline inflation numbers allowed a recession that had already started at the end of 2007 to deteriorate rapidly, pr0viding little or no monetary stimulus, to an economy when nominal income was falling so fast that debts coming due could no longer be serviced. The financial crisis and subsequent Little Depression were caused by the failure of the FOMC to provide stimulus to a failing economy, not by interest rates having been kept too low for too long after 2003. If John Taylor still hasn’t figured that out – and he obviously hasn’t — he should not be allowed anywhere near the Federal Reserve Board.

Milton Friedman, Monetarism, and the Great and Little Depressions

Brad Delong has a nice little piece bashing Milton Friedman, an activity that, within reasonable limits, I consider altogether commendable and like to engage in myself from time to time (see here, here, here, here, here , here, here, here, here and here). Citing Barry Eichengreen’s recent book Hall of Mirrors, Delong tries to lay the blame for our long-lasting Little Depression (aka Great Recession) on Milton Friedman and his disciples whose purely monetary explanation for the Great Depression caused the rest of us to neglect or ignore the work of Keynes and Minsky and their followers in explaining the Great Depression.

According to Eichengreen, the Great Depression and the Great Recession are related. The inadequate response to our current troubles can be traced to the triumph of the monetarist disciples of Milton Friedman over their Keynesian and Minskyite peers in describing the history of the Great Depression.

In A Monetary History of the United States, published in 1963, Friedman and Anna Jacobson Schwartz famously argued that the Great Depression was due solely and completely to the failure of the US Federal Reserve to expand the country’s monetary base and thereby keep the economy on a path of stable growth. Had there been no decline in the money stock, their argument goes, there would have been no Great Depression.

This interpretation makes a certain kind of sense, but it relies on a critical assumption. Friedman and Schwartz’s prescription would have worked only if interest rates and what economists call the “velocity of money” – the rate at which money changes hands – were largely independent of one another.

What is more likely, however, is that the drop in interest rates resulting from the interventions needed to expand the country’s supply of money would have put a brake on the velocity of money, undermining the proposed cure. In that case, ending the Great Depression would have also required the fiscal expansion called for by John Maynard Keynes and the supportive credit-market policies prescribed by Hyman Minsky.

I’m sorry, but I find this criticism of Friedman and his followers just a bit annoying. Why? Well, there are a number of reasons, but I will focus on one: it perpetuates the myth that a purely monetary explanation of the Great Depression originated with Friedman.

Why is it a myth? Because it wasn’t Friedman who first propounded a purely monetary theory of the Great Depression. Nor did the few precursors, like Clark Warburton, that Friedman ever acknowledged. Ralph Hawtrey and Gustav Cassel did — 10 years before the start of the Great Depression in 1919, when they independently warned that going back on the gold standard at the post-World War I price level (in terms of gold) — about twice the pre-War price level — would cause a disastrous deflation unless the world’s monetary authorities took concerted action to reduce the international monetary demand for gold as countries went back on the gold standard to a level consistent with the elevated post-War price level. The Genoa Monetary Conference of 1922, inspired by the work of Hawtrey and Cassel, resulted in an agreement (unfortunately voluntary and non-binding) that, as countries returned to the gold standard, they would neither reintroduce gold coinage nor keep their monetary reserves in the form of physical gold, but instead would hold reserves in dollar or (once the gold convertibility of sterling was restored) pound-denominated assets. (Ron Batchelder and I have a paper discussing the work of Hawtrey and Casssel on the Great Depression; Doug Irwin has a paper discussing Cassel.)

After the short, but fierce, deflation of 1920-21 (see here and here), when the US (about the only country in the world then on the gold standard) led the world in reducing the price level by about a third, but still about two-thirds higher than the pre-War price level, the Genoa system worked moderately well until 1928 when the Bank of France, totally defying the Genoa Agreement, launched its insane policy of converting its monetary reserves into physical gold. As long as the US was prepared to accommodate the insane French gold-lust by permitting a sufficient efflux of gold from its own immense holdings, the Genoa system continued to function. But in late 1928 and 1929, the Fed, responding to domestic fears about a possible stock-market bubble, kept raising interest rates to levels not seen since the deflationary disaster of 1920-21. And sure enough, a 6.5% discount rate (just shy of the calamitous 7% rate set in 1920) reversed the flow of gold out of the US, and soon the US was accumulating gold almost as rapidly as the insane Bank of France was.

This was exactly the scenario against which Hawtrey and Cassel had been warning since 1919. They saw it happening, and watched in horror while their warnings were disregarded as virtually the whole world plunged blindly into a deflationary abyss. Keynes had some inkling of what was going on – he was an old friend and admirer of Hawtrey and had considerable regard for Cassel – but, for reasons I don’t really understand, Keynes was intent on explaining the downturn in terms of his own evolving theoretical vision of how the economy works, even though just about everything that was happening had already been foreseen by Hawtrey and Cassel.

More than a quarter of a century after the fact, and after the Keynesian Revolution in macroeconomics was well established, along came Friedman, woefully ignorant of pre-Keynesian monetary theory, but determined to show that the Keynesian explanation for the Great Depression was wrong and unnecessary. So Friedman came up with his own explanation of the Great Depression that did not even begin until December 1930 when the Fed allowed the Bank of United States to fail, triggering, in Friedman’s telling, a wave of bank failures that caused the US money supply to decline by a third by 1933. Rather than see the Great Depression as a global phenomenon caused by a massive increase in the world’s monetary demand for gold, Friedman portrayed it as a largely domestic phenomenon, though somehow linked to contemporaneous downturns elsewhere, for which the primary explanation was the Fed’s passivity in the face of contagious bank failures. Friedman, mistaking the epiphenomenon for the phenomenon itself, ignorantly disregarded the monetary theory of the Great Depression that had already been worked out by Hawtrey and Cassel and substituted in its place a simplistic, dumbed-down version of the quantity theory. So Friedman reinvented the wheel, but did a really miserable job of it.

A. C. Pigou, Alfred Marshall’s student and successor at Cambridge, was a brilliant and prolific economic theorist in his own right. In his modesty and reverence for his teacher, Pigou was given to say “It’s all in Marshall.” When it comes to explaining the Great Depression, one might say as well “it’s all in Hawtrey.”

So I agree that Delong is totally justified in criticizing Friedman and his followers for giving such a silly explanation of the Great Depression, as if it were, for all intents and purposes, made in the US, and as if the Great Depression didn’t really start until 1931. But the problem with Friedman is not, as Delong suggests, that he distracted us from the superior insights of Keynes and Minsky into the causes of the Great Depression. The problem is that Friedman botched the monetary theory, even though the monetary theory had already been worked out for him if only he had bothered to read it. But Friedman’s interest in the history of monetary theory did not extend very far, if at all, beyond an overrated book by his teacher Lloyd Mints A History of Banking Theory.

As for whether fiscal expansion called for by Keynes was necessary to end the Great Depression, we do know that the key factor explaining recovery from the Great Depression was leaving the gold standard. And the most important example of the importance of leaving the gold standard is the remarkable explosion of output in the US beginning in April 1933 (surely before expansionary fiscal policy could take effect) following the suspension of the gold standard by FDR and an effective 40% devaluation of the dollar in terms of gold. Between April and July 1933, industrial production in the US increased by 70%, stock prices nearly doubled, employment rose by 25%, while wholesale prices rose by 14%. All that is directly attributable to FDR’s decision to take the US off gold, and devalue the dollar (see here). Unfortunately, in July 1933, FDR snatched defeat from the jaws of victory (or depression from the jaws of recovery) by starting the National Recovery Administration, whose stated goal was (OMG!) to raise prices by cartelizing industries and restricting output, while imposing a 30% increase in nominal wages. That was enough to bring the recovery to a virtual standstill, prolonging the Great Depression for years.

I don’t say that the fiscal expansion under FDR had no stimulative effect in the Great Depression or that the fiscal expansion under Obama in the Little Depression had no stimulative effect, but you can’t prove that monetary policy is useless just by reminding us that Friedman liked to assume (as if it were a fact) that the demand for money is highly insensitive to changes in the rate of interest. The difference between the rapid recovery from the Great Depression when countries left the gold standard and the weak recovery from the Little Depression is that leaving the gold standard had an immediate effect on price-level expectations, while monetary expansion during the Little Depression was undertaken with explicit assurances by the monetary authorities that the 2% inflation target – in the upper direction, at any rate — was, and would forever more remain, sacred and inviolable.

Just How Infamous Was that Infamous Open Letter to Bernanke?

There’s been a lot of comment recently about the infamous 2010 open letter to Ben Bernanke penned by an assorted group of economists, journalists, and financiers warning that the Fed’s quantitative easing policy would cause inflation and currency debasement.

Critics of that letter (e.g., Paul Krugman and Brad Delong) have been having fun with the signatories, ridiculing them for what now seems like a chicken-little forecast of disaster. Those signatories who have responded to inquiries about how they now feel about that letter, notably Cliff Asness and Nial Ferguson, have made two arguments: 1) the letter was just a warning that QE was creating a risk of inflation, and 2) despite the historically low levels of inflation since the letter was written, the risk that inflation could increase as a result of QE still exists.

For the most part, critics of the open letter have focused on the absence of inflation since the Fed adopted QE, the critics characterizing the absence of inflation despite QE as an easily predictable outcome, a straightforward implication of basic macroeconomics, which it was ignorant or foolish of the signatories to have ignored. In particular, the signatories should have known that, once interest rates fall to the zero lower bound, the demand for money becoming highly elastic so that the public willingly holds any amount of money that is created, monetary policy is rendered ineffective. Just as a semantic point, I would observe that the term “liquidity trap” used to describe such a situation is actually a slight misnomer inasmuch as the term was coined to describe a situation posited by Keynes in which the demand for money becomes elastic above the zero lower bound. So the assertion that monetary policy is ineffective at the zero lower bound is actually a weaker claim than the one Keynes made about the liquidity trap. As I have suggested previously, the current zero-lower-bound argument is better described as a Hawtreyan credit deadlock than a Keynesian liquidity trap.

Sorry, but I couldn’t resist the parenthetical history-of-thought digression; let’s get back to that infamous open letter.

Those now heaping scorn on signatories to the open letter are claiming that it was obvious that quantitative easing would not increase inflation. I must confess that I did not think that that was the case; I believed that quantitative easing by the Fed could indeed produce inflation. And that’s why I was in favor of quantitative easing. I was hoping for a repeat of what I have called the short but sweat recovery of 1933, when, in the depths of the Great Depression, almost immediately following the worst financial crisis in American history capped by a one-week bank holiday announced by FDR upon being inaugurated President in March 1933, the US economy, propelled by a 14% rise in wholesale prices in the aftermath of FDR’s suspension of the gold standard and 40% devaluation of the dollar, began the fastest expansion it ever had, industrial production leaping by 70% from April to July, and the Dow Jones average more than doubling. Unfortunately, FDR spoiled it all by getting Congress to pass the monumentally stupid National Industrial Recovery Act, thereby strangling the recovery with mandatory wage increases, cost increases, and regulatory ceilings on output as a way to raise prices. Talk about snatching defeat from the jaws of victory!

Inflation having worked splendidly as a recovery strategy during the Great Depression, I have believed all along that we could quickly recover from the Little Depression if only we would give inflation a chance. In the Great Depression, too, there were those that argued either that monetary policy is ineffective – “you can’t push on a string” — or that it would be calamitous — causing inflation and currency debasement – or, even both. But the undeniable fact is that inflation worked; countries that left the gold standard recovered, because once currencies were detached from gold, prices could rise sufficiently to make production profitable again, thereby stimulating multiplier effects (aka supply-side increases in resource utilization) that fueled further economic expansion. And oh yes, don’t forget providing badly needed relief to debtors, relief that actually served the interests of creditors as well.

So my problem with the open letter to Bernanke is not that the letter failed to recognize the existence of a Keynesian liquidity trap or a Hawtreyan credit deadlock, but that the open letter viewed inflation as the problem when, in my estimation at any rate, inflation is the solution.

Now, it is certainly possible that, as critics of the open letter maintain, monetary policy at the zero lower bound is ineffective. However, there is evidence that QE announcements, at least initially, did raise inflation expectations as reflected in TIPS spreads. And we also know (see my paper) that for a considerable period of time (from 2008 through at least 2012) stock prices were positively correlated with inflation expectations, a correlation that one would not expect to observe under normal circumstances.

So why did the huge increase in the monetary base during the Little Depression not cause significant inflation even though monetary policy during the Great Depression clearly did raise the price level in the US and in the other countries that left the gold standard? Well, perhaps the success of monetary policy in ending the Great Depression could not be repeated under modern conditions when all currencies are already fiat currencies. It may be that, starting from an interwar gold standard inherently biased toward deflation, abandoning the gold standard created, more or less automatically, inflationary expectations that allowed prices to rise rapidly toward levels consistent with a restoration of macroeconomic equilibrium. However, in the current fiat money system in which inflation expectations have become anchored to an inflation target of 2 percent or less, no amount of money creation can budge inflation off its expected path, especially at the zero lower bound, and especially when the Fed is paying higher interest on reserves than yielded by short-term Treasuries.

Under our current inflation-targeting monetary regime, the expectation of low inflation seems to have become self-fulfilling. Without an explicit increase in the inflation target or the price-level target (or the NGDP target), the Fed cannot deliver the inflation that could provide a significant economic stimulus. So the problem, it seems to me, is not that we are stuck in a liquidity trap; the problem is that we are stuck in an inflation-targeting monetary regime.

 

Exposed: Irrational Inflation-Phobia at the Fed Caused the Panic of 2008

Matthew O’Brien at The Atlantic has written a marvelous account of the bizarre deliberations of the Federal Open Market Committee at its meetings (June 25 and August 5) before the Lehman debacle on September 15 2008 and its meeting the next day on September 16. A few weeks ago, I wrote in half-seriousness a post attributing the 2008 financial crisis to ethanol because of the runup in corn and other grain prices in 2008 owing to the ethanol mandate and the restrictions on imported ethanol products. But ethanol, as several commenters pointed out, was only a part, probably a relatively small part, of the spike in commodities prices in the summer of 2008. Thanks to O’Brien’s careful reading of the recently released transcripts of the 2008 meetings of the FOMC, we now have a clear picture of how obsessed the FOMC was about inflation, especially the gang of four regional bank presidents, Charles Plosser, Richard Fisher, James Lacker, and Thomas Hoenig, supported to a greater or lesser extent by James Bullard and Kevin Warsh.

On the other hand, O’Brien does point out that two members of the FOMC, Eric Rosengren, President of the Boston Fed, and Fredric Mishkin of the Board of Governors, consistently warned of the dangers of a financial crisis, and consistently objected to and cogently punctured the hysterical inflation fears of the gang of four. It is somewhat, but only somewhat, reassuring that Janet Yellen was slightly more sensitive to the dangers of a financial crisis and less concerned about inflation than Ben Bernanke. Perhaps because he was still getting his feet wet as chairman, Bernanke seems to have been trying to articulate a position that could balance the opposing concerns of the FOMC membership, rather than leading the FOMC in the direction he thought best. While Yellen did not indulge the inflation phobia of the gang of four, she did not strongly support Rosengren and Mishkin in calling for aggressive action to avert the crisis that they clearly saw looming on the horizon.

Here are some highlights from O’Brien’s brilliant piece:

[FOMC Meeting] June 24-25, 2008: 468 mentions of inflation, 44 of unemployment, and 35 of systemic risks/crises

Those numbers pretty much tell you everything you need to know about what happened during the disastrous summer of 2008 at the Fed

Rosengren wasn’t nearly as concerned with 5 percent headline inflation—and with good reason. He reminded his colleagues that “monetary policy is unlikely to have much effect on food and energy prices,” that “total [inflation] has tended to converge to core, and not the opposite,” and that there was a “lack of an upward trend of wages and salaries.”

In short, inflation was high today, but it wouldn’t be tomorrow. They should ignore it. A few agreed. Most didn’t.

Mishkin, Fed Governor Donald Kohn, and then-San Francisco Fed chief Janet Yellen comprised Team: Ignore Inflation. They pointed out that core inflation hadn’t actually risen, and that “inflation expectations remain reasonably well-anchored.” The rest of the Fed, though, was eager to raise rates soon, if not right away. Philadelphia Fed president Charles Plosser recognized that core inflation was flat, but still thought they needed to get ready to tighten “or our credibility could soon vanish.” Fed Governor Kevin Warsh said that “inflation risks, in my view, continue to predominate as the greater risk to the economy,” because he thought headline would get passed into core inflation.

And let us not forget Richard Fisher of the Dallas Fed who provided badly needed comic relief.

And then there was Dallas Fed chief Richard Fisher, who had a singular talent for seeing inflation that nobody else could—a sixth sense, if you will. He was allergic to data. He preferred talking to CEOs instead. But, in Fisher’s case, the plural of anecdote wasn’t data. It was nonsense. He was worried about Frito-Lays increasing prices 9 percent, Budweiser increasing them 3.5 percent, and a small dry-cleaning chain in Dallas increasing them, well, an undisclosed amount. He even half-joked that the Fed was giving out smaller bottles of water, presumably to hide creeping inflation?

By the way, I notice that these little bottles of water have gotten smaller—this will be a Visine bottle at the next meeting. [Laughter]

But it was another member of the Gang of Four who warned ominously:

Richmond Fed president Jeffrey Lacker suggested, that “at some point we’re going to choose to let something disruptive happen.”

Now to the August meeting:

[FOMC Meeting] August 5, 2008: 322 mentions of inflation, 28 of unemployment, and 19 of systemic risks/crises.

Despite evidence that the inflationary blip of spring and summer was winding down, and the real economy was weakening, the Gang of Four continued to press their case for tougher anti-inflation measures. But only Rosengren and Mishkin spoke out against them.

But even though inflation was falling, it was a lonesome time to be a dove. As the Fed’s resident Cassandra, Rosengren tried to convince his colleagues that high headline inflation numbers “appear to be transitory responses to supply shocks that are not flowing through to labor markets.” In other words, inflation would come down on its own, and the Fed should focus on the credit crunch instead. Mishkin worried that “really bad things could happen” if “a shoe drops” and there was a “nasty, vicious spiral” between weak banks and a weak economy. Given this, he wanted to wait to tighten until inflation expectations “actually indicate there is a problem,” and not before.

But Richard Fisher was in no mood to worry about horror stories unless they were about runaway inflation:

The hawks didn’t want to wait. Lacker admitted that wages hadn’t gone up, but thought that “if we wait until wage rates accelerate or TIPS measures spike, we will have waited too long.” He wanted the Fed to “be prepared to raise rates even if growth is not back to potential, and even if financial markets are not yet tranquil.” In other words, to fight nonexistent wage inflation today to prevent possible wage inflation tomorrow, never mind the crumbling economy. Warsh, for his part, kept insisting that “inflation risks are very real, and I believe that these are higher than growth risks.” And Fisher had more”chilling anecdotes”—as Bernanke jokingly called them—about inflation. This time, the culprit was Disney World and its 5 percent price increase for single-day tickets.

The FOMC was divided, but the inflation-phobes held the upper hand. Unwilling to challenge them, Bernanke appeased them by promising that his statement about future monetary policy after the meeting would be “be slightly hawkish—to indicate a slight uplift in policy.”

Frightened by what he was hearing, Mishkin reminded his colleagues of some unpleasant monetary history:

Remember that in the Great Depression, when—I can’t use the expression because it would be in the transcripts, but you know what I’m thinking—something hit the fan, [laughter] it actually occurred close to a year after the initial negative shock.

Mishkin also reminded his colleagues that the stance of monetary policy cannot be directly inferred from the federal funds rate.

I just very much hope that this Committee does not make this mistake because I have to tell you that the situation is scary to me. I’m holding two houses right now. I’m very nervous.

And now to the September meeting, the day after Lehman collapsed:

[FOMC meeting] September 16, 2008: 129 mentions of inflation, 26 of unemployment, and 4 of systemic risks/crises

Chillingly, Lacker and Hoenig did a kind of victory dance about the collapse of Lehman Brothers.

Lacker had gotten the “disruptive” event he had wanted, and he was pretty pleased about it. “What we did with Lehman I obviously think was good,” he said, because it would “enhance the credibility of any commitment that we make in the future to be willing to let an institution fail.” Hoenig concurred that it was the “right thing,” because it would suck moral hazard out of the market.

The rest of the Gang of Four and their allies remained focused like a laser on inflation.

Even though commodity prices and inflation expectations were both falling fast, Hoenig wanted the Fed to “look beyond the immediate crisis,” and recognize that “we also have an inflation issue.” Bullard thought that “an inflation problem is brewing.” Plosser was heartened by falling commodity prices, but said, “I remain concerned about the inflation outlook going forward,” because “I do not see the ongoing slowdown in economic activity is entirely demand driven.” And Fisher half-jokingly complained that the bakery he’d been going to for 30 years—”the best maker of not only bagels, but anything with Crisco in it”—had just increased prices. All of them wanted to leave rates unchanged at 2 percent.

Again, only Eric Rosengren seemed to be in touch with reality, but no was listening:

[Rosengren] was afraid that exactly what did end up happening would happen. That all the financial chaos “would have a significant impact on the real economy,” that “individuals and firms will be become risk averse, with reluctance to consume or invest,” that “credit spreads are rising, and the cost and availability of financing is becoming more difficult,” and that “deleveraging is likely to occur with a vengeance.” More than that, he thought that the “calculated bet” they took in letting Lehman fail would look particularly bad “if we have a run on the money market funds or if the nongovernment tri-party repo market shuts down.” He wanted to cut rates immediately to do what they could to offset the worsening credit crunch. Nobody else did.

Like Bernanke for instance. Here is his take on the situation:

Overall I believe that our current funds rate setting is appropriate, and I don’t really see any reason to change…. Cutting rates would be a very big step that would send a very strong signal about our views on the economy and about our intentions going forward, and I think we should view that step as a very discrete thing rather than as a 25 basis point kind of thing. We should be very certain about that change before we undertake it because I would be concerned, for example, about the implications for the dollar, commodity prices, and the like.

OMG!

O’Brien uses one of my favorite Hawtrey quotes to describe the insanity of the FOMC deliberations:

In other words, the Fed was just as worried about an inflation scare that was already passing as it was about a once-in-three-generations crisis.

It brought to mind what economist R. G. Hawtrey had said about the Great Depression. Back then, central bankers had worried more about the possibility of inflation than the grim reality of deflation. It was, Hawtrey said, like “crying Fire! Fire! in Noah’s flood.”

In any non-dysfunctional institution, the perpetrators of this outrage would have been sacked. But three of Gang of Four (Hoenig having become a director of the FDIC in 2012) remain safely ensconced in their exalted positions, blithely continuing, without the slightest acknowledgment of their catastrophic past misjudgments, to exert a malign influence on monetary policy. For shame!

How Monetary Policy Works

These are exciting times. Europe is in disarray, unable to cope with a crisis requiring adjustments in relative prices, wages, and incomes that have been rendered impossible by a monetary policy that has produced almost no growth in nominal GDP in the Eurozone since 2008, placing an intolerable burden on the Eurozone’s weakest economies. The required monetary easing by the European Central Bank is unacceptable to Germany, so the process of disintegration continues. The US, showing signs of gradual recovery in the winter and early spring, remains too anemic to shake off the depressing effects of the worsening situation in Europe. With US fiscal policy effectively stalemated until after the election, the only policy-making institution still in play is the Federal Open Market Committee (FOMC) of the Federal Reserve. The recent track record of the FOMC can hardly inspire much confidence in its judgment, but it’s all we’ve got. Yesterday’s stock market rally shows that the markets, despite many earlier disappointments, have still not given up on the FOMC.  But how many more disappointments can they withstand?

In today’s Financial Times, Peter Fisher (head of fixed income at BlackRock) makes the case (“Fed would risk diminishing returns with further ‘QE'”) against a change in policy by the Fed. Fisher lists four possible policy rationales for further easing of monetary policy by the Fed: 1) the “bank liquidity” rationale, 2) the “asset price” rationale, 3) the “credit channel” rationale, and 4) the “radical monetarist” rationale.

Fisher dismisses 1), because banks are awash in excess reserves from previous bouts of monetary easing. I agree, and that’s why the Fed should stop paying banks interest on reserves. He dismisses 2) because earlier bouts of monetary easing raised asset prices but had only very limited success in stimulating increased output.

While [the Fed] did drive asset prices higher for a few months, there was little follow-through in economic activity in 2011. This approach provides little more than a bridging operation and the question remains: a bridge to what?

This is not a persuasive critique. Increased asset prices reflected a partial recovery in expectations of future growth in income and earnings. A credible monetary policy with a clearly articulated price level of NGDP target would have supported expectations of higher growth than the anemic growth since 2009, in which asset prices would have risen correspondingly higher, above the levels in 2007, which we have still not reached again.

Fisher rejects 3), the idea “that if the Fed holds down long-term interest rates it will stimulate private credit creation and, thus, economic expansion.” Implementing this idea, via “operation twist” implies taking short-term Treasuries out of the market and replacing them with longer-term Treasuries, but doing so denies “banks the core asset on which they build their balance sheets,” thus impairing the provision of credit by the banking system instead of promoting it.

I agree.

Finally Fisher rejects 4), “the idea more central bank liabilities will eventually translate into ‘too much money chasing too few goods and services’ at least so as to avoid a fall in the general price level.” Fisher asks:

What assets would the Fed buy? More Treasuries? Would the Fed embark on such a radical course in a presidential election year?

Perhaps the Fed could buy foreign currencies, engineer a much weaker dollar and, thereby, stimulate inflation and growth. Would the rest of the world permit this? I doubt it. They would probably respond in kind and we would all have a real currency war. Nor is it clear the US external sector is large enough to import enough inflation to make a difference. If energy and commodity prices soared, would American consumers “chase” consumption opportunities or would they suppress consumption and trigger a recession? Recent experience suggests the latter. How much “chasing behaviour” would we get in a recession? Engineering a dollar collapse would be to play with fire and gasoline. It might create inflation or it might create a depression.

These are concerns that have been expressed before, especially in astute and challenging comments by David Pearson to many of my posts on this blog. They are not entirely misplaced, but I don’t think that they are weighty enough to undermine the case for monetary easing, especially monetary easing tied to an explicit price level or NGDP target. As I pointed out in a previous post, Ralph Hawtrey addressed the currency-war argument 80 years ago in the middle of the Great Depression, and demolished it. FDR’s 40-percent devaluation of the dollar in 1933, triggering the fastest four-month expansion in US history, prematurely aborted by the self-inflicted wound of the National Recovery Administration, provides definitive empirical evidence against the currency-war objection. As for the fear that monetary easing and currency depreciation would lead to an upward spiral of energy and commodity prices that would cause a retrenchment of consumer spending, thereby triggering a relapse into recession, that is certainly a risk. But if you believe that we are in a recession with output and employment below the potential output and employment that the economy could support, you would have to be awfully confident that that scenario is the most likely result of monetary easing in order not to try it.

The point of tying monetary expansion to an explicit price level or spending target is precisely to provide a nominal anchor for expectations. That nominal anchor would provide a barrier against the kind of runaway increase in energy and commodity prices that would supposedly follow from a commitment to use monetary policy to achieve a price-level or spending target.  Hawtrey’s immortal line about crying “fire, fire” in Noah’s flood is still all too apt.

More on Inflation Expectations and Stock Prices

It was three and a half weeks ago (May 14) that I wrote a post “Inflation Expectations Are Falling; Run for Cover” in which I called attention to the fact that inflation expectations, which had been rising since early in 2012, had begun to fall, and that the shift had coincided with falling stock prices. I included in that post the chart below showing the close correlation between inflation expectations (approximated by the breakeven TIPS spread on 10-year constant-maturity Treasuries and 10-year constant-maturity TIPS).

Then I noted in two posts (May 24 and May 30) that since early in May, I had detected an anomaly in the usual close correlation between short-term and long-term real interest rates, longer-term real interest rates having fallen more sharply than shorter-term real interest rates since the start of May. That was shown in the chart below.

I thought it would now be useful to look at my chart from May 14 with the additional observations from the past three weeks included. The new version of the May 14 chart is shown below.

What does it teach us? There still seems to be a correlation between inflation expectations and stock prices, but it is not as close as it was until three weeks ago. I confirmed this by computing the correlation coefficient between inflation expectations and the S&P 500 from January 3 to May 14. The correlation was .9. Since May 14, the correlation is only .4. That is a relatively weak correlation, but one should note that there are other three-week periods between January 3 and May 14 in which the correlation between inflation expectations and stock prices is even lower than .4. Still, one can’t exclude the possibility that the last three weeks involve some change in circumstances that has altered the relationship between inflation expectations and stock prices. The chart below plots the movement in inflation expectations and stock prices for just the last three weeks.

One other point bears mentioning: the sharp increase in stock prices yesterday was accompanied by increases in nominal and real interest rates, for all durations. That is not an anomalous result; it has been the typical relationship since the early stages of the Little Depression.  Expected inflation implies increased nominal rates and increased borrowing costs.  Moreover, expected inflation has generally been positively correlated with real interest rates, expectations of increased inflation being correlated with expectation of increased real returns on investment.  So the conventional textbook theory that loose monetary policy increases stock prices and economic activity by reducing borrowing costs is simply not reflected in the data since the start of the Little Depression.

Expected Inflation and the S&P 500 Redux

On Monday I wrote a post with the chart below showing the close correlation since January of this year between the S&P 500 and expected inflation as (approximately) reflected in the spread between the constant maturity 10-year Treasury note and the constant maturity 10-year TIPS.  A number of other bloggers noticed the post and the chart.  One of those was Matthew Yglesias who coupled my chart with a somewhat similar one posted by Marcus Nunes on his blog on the same day as mine.

One commenter (“Fact Checker”) on Matthew’s blog criticized my chart accusing me of cherry picking.

The second graph is meaningless, as it does not work through time.

Here it is from 1990: http://research.stlouisfed.org/fredgraph.png?g=7gX
Again from 2000: http://research.stlouisfed.org/fredgraph.png?g=7gY
From 2005: http://research.stlouisfed.org/fredgraph.png?g=7gZ
From 2009: http://research.stlouisfed.org/fredgraph.png?g=7h0

And in another comment:

The S&P + inflation chart is reproduced below, with longer windows. And as you suggest there is no correlation in any time frame but the very short window cherry picked by MY.

Two points to make about his comment.  First, if Fact Checker had read Yglesias’s post carefully, or, better yet, actually read my post (let alone the original paper on which the post was based), he would have realized that my whole point is that the close correlation between expected inflation and stock prices is generally not observed, and that one would expect to observe the correlation only when deflation exceeds the real rate of interest (as it does now when slightly positive expected inflation exceeds the negative real real rate of interest).  So the fact that the correlation doesn’t work through time was precisely the point of my post.  Second, the graphs to which Fact Checker links use survey data by the University of Michigan of the inflation expectations of households.  I do not totally discount such data, but I regard survey estimates of expected inflation as much less reliable than the implicit market expectations of inflation reflected in the TIPS spread.

To show that the correlation I have found is reflected in the data since approximately the beginning of the downturn at the very end of 2007, but not before, here is a graph similar to the one I posted on Monday covering the entire period since 2003 for which I have data on the 10-year TIPS spread.

Before the beginning of 2008, there is plainly no correlation at all between inflation expectations and stock prices.  It is only at some point early in 2008 that the correlation begins to be observed, and it has persisted ever since.  We will know that we are out of this Little Depression when the correlation vanishes.


About Me

David Glasner
Washington, DC

I am an economist in the Washington DC area. My research and writing has been mostly on monetary economics and policy and the history of economics. In my book Free Banking and Monetary Reform, I argued for a non-Monetarist non-Keynesian approach to monetary policy, based on a theory of a competitive supply of money. Over the years, I have become increasingly impressed by the similarities between my approach and that of R. G. Hawtrey and hope to bring Hawtrey’s unduly neglected contributions to the attention of a wider audience.

My new book Studies in the History of Monetary Theory: Controversies and Clarifications has been published by Palgrave Macmillan
