They Come not to Praise Market Monetarism, but to Bury It

For some reason – maybe he is still annoyed with Scott Sumner – Paul Krugman decided to channel a post by Mike Konczal purporting to show that Market Monetarism has been refuted by the preliminary first quarter GDP numbers showing NGDP increasing at a 3.7% rate and real GDP increasing at a 2.5% rate in Q1. To Konczal and Krugman (hereinafter K&K) this shows that fiscal policy, not monetary policy, is what matters most for macroeconomic performance. Why is that? Because the Fed, since embarking on its latest splurge of bond purchasing last September, has failed to stimulate economic activity in the face of the increasingly contractionary stance of fiscal policy since them (the fiscal 2013 budget deficit recently being projected to be $775 billion, a mere 4.8% of GDP).

So can we get this straight? GDP is now rising at about the same rate it has been rising since the start of the “recovery” from the 2007-09 downturn. Since September monetary policy has become easier and fiscal policy tighter. And that proves what? Sorry, I still don’t get it. But then again, I was always a little slow on the uptake.

Marcus Nunes, the Economist, Scott Sumner, and David Beckworth all weigh in on the not very devastating K&K onslaught. (Also see this post by Evan Soltas written before the fact.) But let me try to cool things down a bit.

If we posit that we are still in something akin to a zero-lower-bound situation, there are perfectly respectable theoretical grounds on which to recommend both fiscal and monetary stimulus. It is true that monetary policy, in principle, could stimulate a recovery even without fiscal stimulus — and even in the face of fiscal contraction — but for monetary policy to be able to be that effective, it would have to operate through the expectations channel, raising price-level expectations sufficiently to induce private spending. However, for good or ill, monetary policy is not aiming at more than a marginal change in inflation expectations. In that kind of policy environment, the potential effect of monetary policy is sharply constrained. Hence, the monetary theoretical case for fiscal stimulus. This is classic Hawtreyan credit deadlock (see here and here).

If monetary policy can’t do all the work by itself, then the question is whether fiscal policy can help. In principle it could if the Fed is willing to monetize the added debt generated by the fiscal stimulus. But there’s the rub. If the Fed has to monetize the added debt created by the fiscal stimulus — which, for argument’s sake, let us assume is more stimulative than equivalent monetary expansion without the fiscal stimulus — what are we supposed to assume will happen to inflation and inflation expectations?

Here is the internal contradiction – the Sumner critique, if you will – implicit in the Keynesian fiscal-policy prescription. Can fiscal policy work without increasing the rate of inflation or inflation expectations? If monetary policy alone cannot work, because it cannot break through the inflation targeting regime that traps us at the 2 percent inflation ceiling, how is fiscal policy supposed to work its way around the 2% inflation ceiling, except by absolving monetary policy of the obligation to keep inflation at or below the ceiling? But if we can allow the ceiling to be pierced by fiscal policy, why can’t we allow it to be pierced by monetary policy?

Perhaps K&K can explain that one to us.

Hawtrey and the “Treasury View”

Mention the name Ralph Hawtrey to most economists, even, I daresay to most monetary economists, and you are unlikely to get much more than a blank stare. Some might recognize the name because of it is associated with Keynes, but few are likely to be able to cite any particular achievement or contribution for which he is remembered or worth remembering. Actually, your best chance of eliciting a response about Hawtrey might be to pose your query to an acolyte of Austrian Business Cycle theory, for whom Hawtrey frequently serves as a foil, because of his belief that central banks ought to implement a policy of price-level (actually wage-level) stabilization to dampen the business cycle, Murray Rothbard having described him as “one of the evil genius of the 1920s” (right up there, no doubt, with the likes of Lenin, Trotsky, Stalin and Mussolini). But if, despite the odds, you found someone who knew something about Hawtrey, there’s a good chance that it would be for his articulation of what has come to be known as the “Treasury View.”

The Treasury View was a position articulated in 1929 by Winston Churchill, then Chancellor of the Exchequer in the Conservative government headed by Stanley Baldwin, in a speech to the House of Commons opposing proposals by Lloyd George and the Liberals, supported notably by Keynes, to increase government spending on public-works projects as a way of re-employing the unemployed. Churchill invoked the “orthodox Treasury View” that spending on public works would simply divert an equal amount of private spending on other investment projects or consumption. Spending on public-works projects was justified if and only if the rate of return over cost from those projects was judged to be greater than the rate of return over cost from alternative private spending; public works spending could not be justified as a means by which to put the unemployed back to work. The theoretical basis for this position was an article published by Hawtrey in 1925 “Public Expenditure and the Demand for Labour.”

Exactly how Hawtrey’s position first articulated in a professional economics journal four years earlier became the orthodox Treasury View in March 1929 is far from clear. Alan Gaukroger in his doctoral dissertation on Hawtrey’s career at the Treasury provides much helpful background information. Apparently, Hawtrey’s position was elevated into the “orthodox Treasury View” because Churchill required some authority on which to rely in opposing Liberal agitation for public-works spending which the Conservative government and Churchill’s top Treasury advisers and the Bank of England did not want to adopt for a variety of reason. The “orthodox Treasury View” provided a convenient and respectable doctrinal cover with which to clothe their largely political opposition to public-works spending. This is not to say that Churchill and his advisers were insincere in taking the position that they did, merely that Churchill’s position emerged from on-the-spot political improvisation in the course of which Hawtrey’s paper was dredged up from obscurity rather than from applying any long-standing, well-established, Treasury doctrine. For an illuminating discussion of all this, see chapter 5 (pp. 234-75) of Gaukroger’s dissertation.

I have seen references to the Treasury View for a very long time, probably no later than my first year in graduate school, but until a week or two ago, I had never actually read Hawtrey’s 1925 paper. Brad Delong, who has waged a bit of a campaign against the Treasury View on his blog as part of his larger war against opponents of President Obama’s stimulus program, once left a comment on a post of mine about Hawtrey’s explanation of the Great Depression, asking whether I would defend Hawtrey’s position that public-works spending would not increase employment. I think I responded by pleading ignorance of what Hawtrey had actually said in his 1925 article, but that Hawtrey’s explanation of the Great Depression was theoretically independent of his position about whether public-works spending could increase employment. So in a sense, this post is partly belated reply to Delong’s query.

The first thing to say about Hawtrey’s paper is that it’s hard to understand. Hawtrey is usually a very clear expositor of his ideas, but sometimes I just can’t figure out what he means. His introductory discussion of A. C. Pigou’s position on the wisdom of concentrating spending on public works in years of trade depression was largely incomprehensible to me, but it is worth reading, nevertheless, for the following commentary on a passage from Pigou’s Wealth and Welfare in which Pigou proposed to “pass behind the distorting veil of money.”

Perhaps if Professsor Pigou had carried the argument so far, he would have become convinced that the distorting veil of money cannot be put aside. As well might he play lawn tennis without the distorting veil of the net. All the skill and all the energy emanate from the players and are transmitted through the racket to the balls. The net does nothing; it is a mere limiting condition. So is money.

Employment is given by producers. They produce in response to an effective demand for products. Effective demand means ultimately money, offered by consumers in the market.

A wonderful insight, marvelously phrased, but I can’t really tell, beyond Pigou’s desire to ignore the “distorting veil of money,” how it relates to anything Pigou wrote. At any rate, from here Hawtrey proceeds to his substantive argument, positing “a community in which there is unemployment.” In other words, “at the existing level of prices and wages, the consumers’ outlay [Hawtrey's term for total spending] is sufficient only to employ a part of the productive resources of the country.” Beyond the bare statement that spending is insufficient to employ all resources at current prices, no deeper cause of unemployment is provided. The problem Hawtrey is going to address is what happens if the government borrows money to spend on new public works?

Hawtrey starts by assuming that the government borrows from private individuals (rather than from the central bank), allowing Hawtrey to take the quantity of money to be constant through the entire exercise, a crucial assumption. The funds that the government borrows therefore come either from that portion of consumer income that would have been saved, in which case they are not available to be spent on whatever private investment projects they would otherwise have financed, or they are taken from idle balances held by the public (the “unspent margin” in Hawtrey’s terminology). If the borrowed funds are obtained from cash held by the public, Hawtrey argues that the public will gradually reduce spending in order to restore their cash holdings to their normal level. Thus, either way, increased government spending financed by borrowing must be offset by a corresponding reduction in private spending. Nor does Hawtrey concede that there will necessarily be a temporary increase in spending, because the public may curtail expenditures to build up their cash balances in anticipation of lending to the government. Moreover, there is always an immediate effect on income from any form of spending (Hawtrey understood the idea of a multiplier effect, having relied on it in his explanation of how an increase in the stock of inventories held by traders in response to a cut in interest rates would produce a cumulative increase in total income and spending), so if government spending on public works reduces spending elsewhere, there is no necessary net increase in total spending even in the short run. Here is how Hawtrey sums up the crux of his argument.

To show why this does not happen, we must go back to consider the hypothesis with which we started. We assumed that no additional bank credits are created. It follows that there is no increase in the supply of the means of payment. As soon as the people employed on the new public works begin to receive payment, they will begin to accumulate cash balances and bank balances. Their balances can only be provided at the expense of the people already receiving incomes. These latter will therefore become short of ready cash and will curtail their expenditures with a view to restoring their balances. An individual can increase his balance by curtailing his expenditure, but if the unspent margin (that is to say, the total of all cash balances and bank balances) remains unchanged, he can only increase his balance at the expense of those of his neighbours. If all simultaneously try to increase their balances, they try in vain. The effect can only be that sales of goods are diminished, and the consumers’ income is reduced as much as the consumers’ outlay. In the end the normal proportion between the consumers’ income and the unspent margin is restored, not by an increase in balances, but by a decrease in incomes. It is this limitation of the unspent margin that really prevents the new Government expenditure from creating employment. (pp. 41-42)

Stated in these terms, the argument suggests another possible mechanism by which government expenditure could increase total income and employment: an increase in velocity. And Hawtrey explicitly recognized it.

There is, however, one possibility which would in certain conditions make the Government operations the means of a real increase in the rapidity of circulation. In a period of depression the rapidity of circulation is low, because people cannot find profitable outlets for their surplus funds and they accumulate idle balances. If the Government comes forward with an attractive gild-edged loan, it may raise money, not merely by taking the place of other possible capital issues, but by securing money that would otherwise have remained idle in balances. (pp. 42-43)

In other words, Hawtrey did indeed recognize the problem of a zero lower bound (in later works he called it a “credit deadlock”) in which the return to holding money exceeds the expected return from holding real capital assets, and that, in such circumstances, government spending could cause aggregate spending and income to increase.

Having established that, absent any increase in cash balances, government spending would have stimulative effects only at the zero lower bound, Hawtrey proceeded to analyze the case in which government spending increased along with an increase in cash balances.

In the simple case where the Government finances its operations by the creation of bank credits, there is no diminution in the consumers’ outlay to set against the new expenditure. It is not necessary for the whole of the expenditure to be so financed. All that is required is a sufficient increase in bank credits to supply balances of cash and credit for those engaged in the new enterprise, without diminishing the balances held by the rest of the community. . . . If the new works are financed by the creation of bank credits, they will give additional employment. (p. 43)

After making this concession, however, Hawtrey added a qualification, which has provoked the outrage of many Keynesians.

What has been shown is that expenditure on public works, if accompanied by a creation of credit, will give employment. But then the same reasoning shows that a creation of credit unaccompanied by any expenditure on public works would be equally effective in giving employment.

The public works are merely a piece of ritual, convenient to people who want to be able to say that they are doing something, but otherwise irrelevant. To stimulate an expansion of credit is usually only too easy. To resort for the purpose to the construction of expensive public works is to burn down the house for the sake of the roast pig.

That applies to the case where the works are financed by credit creation. In the practical application of the policy, however, this part of the programme is omitted. The works are started by the Government at the very moment when the central bank is doing all it can to prevent credit from expanding. The Chinaman burns down his house in emulation of his neighbour’s meal of roast pork, but omits the pig.

Keynesians are no doubt offended by the dismissive reference to public-works spending as “a piece of ritual.” But it is worth recalling the context in which Hawtrey published his paper in 1925 (read to the Economics Club on February 10). Britain was then in the final stages of restoring the prewar dollar-sterling parity in anticipation of formally reestablishing gold convertibility and the gold standard. In order to accomplish this goal, the Bank of England raised its bank rate to 5%, even though unemployment was still over 10%. Indeed, Hawtrey did favor going back on the gold standard, but not at any cost. His view was that the central position of London in international trade meant that the Bank of England had leeway to set its bank rate, and other central banks would adjust their rates to the bank rate in London. Hawtrey may or may not have been correct in assessing the extent of the discretionary power of the Bank of England to set its bank rate. But given his expansive view of the power of the Bank of England, it made no sense to Hawtrey that the Bank of England was setting its bank rate at 5% (historically a rate characterizing periods of “dear money” as Hawtrey demonstrated subsequently in his Century of Bank Rate) in order to reduce total spending, thereby inducing an inflow of gold, while the Government simultaneously initiated public-works spending to reduce unemployment. The unemployment was attributable to the restriction of spending caused by the high bank rate, so the obvious, and most effective, remedy for unemployment was a reduced bank rate, thereby inducing an automatic increase in spending. Given his view of the powers of the Bank of England, Hawtrey felt that the gold standard would take care of itself. But even if he was wrong, he did not feel that restoring the gold standard was worth the required contraction of spending and employment.

From the standpoint of pure monetary analysis, notwithstanding all the bad press that the “Treasury View” has received, there is very little on which to fault the paper that gave birth to the “Treasury View.”

Robert Waldmann, WADR, Maybe You Really Should Calm Down

Responding to this recent post of mine, Robert Waldmann wrote a post of his own with a title alluding to an earlier post of mine responding to a previous post of his. Just to recapitulate briefly, the point of the post which seems to have provoked Professor Waldmann was to refute the allegation that the Fed and the Bank of Japan are starting a currency war by following a policy of monetary ease in which they are raising (at least temporarily) their inflation target. I focused my attention on a piece written by Irwin Stelzer for the Weekly Standard, entitled not so coincidentally, “Currency Wars.” I also went on to point out that Stelzer, in warning of the supposedly dire consequences of starting a currency war, very misleadingly suggested that Hitler’s rise to power was the result of an inflationary policy followed by Germany in the 1930s.

Here is how Waldmann responds:

I do not find any reference to the zero lower bound in this post.  Your analysis of monetary expansion does not distinguish between the cases when the ZLB holds and when it doesn’t.  You assume that the effect of an expansion of the money supply on domestic demand can be analyzed ignoring that detail. I think it is clear that the association between the money supply and domestic demand has been different in the USA since oh September 2008 than it was before.  This doesn’t seem to me to be a detail which can be entirely overlooked in any discussion of current policy.

Actually, I don’t think that, in principle, I disagree with any of this. I agree that the zero lower bound is relevant to the analysis of the current situation. I prefer to couch the analysis in terms of the Fisher equation making use of the equilibrium condition that the nominal rate of interest must equal the real rate plus expected inflation. If the expected rate of deflation is greater than the real rate, equilibrium is impossible and the result is a crash of asset prices, which is what happened in 2008. But as long as the real rate of interest is negative (presumably because of pessimistic entrepreneurial expectations), the rate of inflation has to be sufficiently above real rate of interest for nominal rates to be comfortably above zero. As long as nominal rates are close to zero and real rates are negative, the economy cannot be operating in the neighborhood of full-employment equilibrium. I developed the basic theory in my paper “The Fisher Effect Under Deflationary Expectations” available on SSRN, and provided some empirical evidence (which I am hoping to update soon) that asset prices (as reflected in the S&P 500) since 2008 have been strongly correlated with expected inflation (as approximated by the TIPS spread) even though there is no strong theoretical reason for asset prices to be correlated with expected inflation, and no evidence of correlation before 2008. Although I think that this is a better way than the Keynesian model to think about why the US economy has been underperforming so badly since 2008, I don’t think that the models are contradictory or inconsistent, so I don’t deny that fiscal policy could have some stimulative effect. But apparently that is not good enough for Professor Waldmann.

Also, I note that prior to his [Stelzer's] “jejune dismissal of monetary policy,” Stelzer jenunely dismissed fiscal policy.  You don’t mention this at all.  Your omission is striking, since the evidence that Stelzer is wrong to dismiss fiscal policy is overwhelming (not overwhelming enough to overwhelm John Taylor but then mere evidence couldn’t do that).  In contrast, the dismissal of monetary policy when an economy is in a liquidity trap is consistent with the available evidence.

It seems to me that Waldmann is being a tad oversensitive. Stelzer’s line was “stimulus packages don’t work very well, and monetary policy produces lots of fiat money but not very many jobs.” What was jejune was not the conclusion that fiscal policy and monetary policy aren’t effective; it was his formulation that monetary expansion produces lots of fiat money but not many jobs, a formulation which, I believe, was intended to be clever, but struck me as being not clever, but, well, jejune. So I did not mean to deny that fiscal policy could be effective at the zero lower bound, but I disagree that the available evidence is consistent with the proposition that monetary policy is ineffective in a liquidity trap. In 1933, for example, monetary policy triggered the fastest economic expansion in US history, when FDR devalued the dollar shortly after taking office, an expansion unfortunately prematurely terminated by the enactment of FDR’s misguided National Industrial Recovery Act. The strong correlation between inflation expectations and stock prices since 2008, it seems to me, also qualifies as evidence that monetary policy is not ineffective at the zero lower bound. But if Professor Waldmann has a different interpretation of the significance of that correlation, I would be very interested in hearing about it.

Instead of looking at the relationship between inflation expectations and stock prices, Waldmann wants to look at the relationship between job growth and monetary policy:

I hereby challenge you to show data on US “growth”  meaning (I agree with your guess) mostly employment growth since 2007 to someone unfamiliar with the debate and ask that person to find the dates of shifts in monetary policy.  I am willing to bet actual money (not much I don’t have much) that the person will not pick out QEIII or operation twist.    I also guess that this person will not detect forward guidance looking at day to day changes in asset prices.

I claim that the null that nothing special happened the day QEIV was announced or any of the 4 plausible dates of announcement of QE2 (starting with a FOMC meeting, then Bernanke’s Jackson Hole speech then 2 more) can’t be rejected by the data. This is based on analysis by two SF FED economists who look at the sum of changes over three of the days (not including the Jackson Hole day when the sign was wrong) and get a change (of the sign they want) whose square is less than 6 times the variance of daily changes (of the 10 year rate IIRC).  IIRC 4.5 times.  Cherry picking and not rejecting the null one wants to reject is a sign that one’s favored (alternative) hypothesis is not strongly supported by the data.

I think that the way to pick out changes in monetary policy is to look at changes in inflation expectations, and I think that you can find some correlation between changes in monetary policy, so identified, and employment, though it is probably not nearly as striking as the relationship between asset prices and inflation expectations. I also don’t think that operation twist had any positive effect, but QE3 does seem to have had some. I am not familiar with the study by the San Francisco Fed economists, but I will try to find it and see what I can make out of it. In the meantime, even if Waldmann is correct about the relationship between monetary policy and employment since 2008, there are all kinds of good reasons for not rushing to reject a null hypothesis on the basis of a handful of ambiguous observations. That wouldn’t necessarily be the calm and reasonable thing to do.

Maybe Robert Waldmann Should Calm Down

Robert Waldmann is unhappy with Matthew Yglesias for being hopeful that, Shinzo Abe, just elected prime minister of Japan, may be about to make an important contribution to the world economy, and to economic science, by prodding the Bank of Japan to increase its inflation target and by insisting that the BOJ actually hit the new target. Since I don’t regularly read Waldmann’s blog (not because it’s not worth reading — I usually enjoy reading it when I get to it – I just can’t keep up with that many blogs), I’m not sure why Waldmann finds Yglesias’s piece so annoying. OK, Waldmann’s a Keynesian and prefers fiscal to monetary policy, but so is Paul Krugman, and he thinks that monetary policy can be effective even at the zero lower bound. At any rate this is how Waldmann responds to Yglesias:

Ben Bernanke too has declared a policy of unlimited quantitative easing and increased inflation (new target only 2.5% but that’s higher than current inflation).  The declaration (which was a surprise) had essentially no effect on prices for medium term treasuries, TIPS or the breakeven.

I was wondering when you would comment, since you have confidently asserted again and again that if only the FOMC did what it just did, expected inflation would jump and then GDP growth would increase.

However, instead of noting the utter total failure of your past predictions (and the perfect confirmation of mine) you just boldly make new predictions.

Face fact,  like conventional monetary policy (in the US the Federal Funds rate) forward guidance is pedal to the metal.   It’s long past time for you to start climbing down.

I mention this, because just yesterday I happened across another blog post about what Bernanke said after the FOMC meeting.  This post by David Altig, executive VP and research director of the Atlanta Fed, was on the macroblog. Altig points out that, despite the increase in the Fed’s inflation threshold from 2 to 2.5%, the Fed increased neither its inflation target (still 2%) nor its inflation forecast (still under 2%). All that the Fed did was to say that it won’t immediately slam on the brakes if inflation rises above 2% provided that unemployment is greater than 6.5% and inflation is less than 2.5%. That seems like a pretty marginal change in policy to me.

Also have a look at this post from earlier today by Yglesias, showing that the Japanese stock market has risen about 5.5% in the last two weeks, and about 2% in the two days since Abe’s election. Here is Yglesias’s chart showing the rise of the Nikkei over the past two weeks.

In addition, here is a news story from Bloomberg about rising yields on Japanese government bonds, which are now the highest since April.

Japan‘s bonds declined, sending 20- year yields to an eight-month high, as demand ebbed at a sale of the securities and domestic shares climbed.

The sale of 1.2 trillion yen ($14.3 billion) of 20-year bonds had the lowest demand in four months. Yields on the benchmark 10-year note rose to a one-month high as Japan’s Nikkei 225 Stock Average reached the most since April amid signs U.S. budget talks are progressing.

Finally, another item from Yglesias, a nice little graph showing the continuing close relationship between the S&P 500 and inflation expectations as approximated by the breakeven TIPS spread on 10-year Treasuries, a relationship for which I have provided (in a paper available here) a theoretical explanation as well as statistical evidence that the relationship did not begin to be observed until approximately the spring of 2008 as the US economy, even before the Lehman debacle, began its steep contraction. Here’s the graph.

About Me

David Glasner
Washington, DC

I am an economist at the Federal Trade Commission. Nothing that you read on this blog necessarily reflects the views of the FTC or the individual commissioners. Although I work at the FTC as an antitrust economist, most of my research and writing has been on monetary economics and policy and the history of monetary theory. 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.
