What’s so Bad about the Gold Standard?

Last week Paul Krugman argued that Ted Cruz is more dangerous than Donald Trump, because Trump is merely a protectionist while Cruz wants to restore the gold standard. I’m not going to weigh in on the relative merits of Cruz and Trump, but I have previously suggested that Krugman may be too dismissive of the possibility that the Smoot-Hawley tariff did indeed play a significant, though certainly secondary, role in the Great Depression. In warning about the danger of a return to the gold standard, Krugman is certainly right that the gold standard was and could again be profoundly destabilizing to the world economy, but I don’t think he did such a good job of explaining why, largely because, like Ben Bernanke and, I am afraid, most other economists, Krugman isn’t totally clear on how the gold standard really worked.

Here’s what Krugman says:

[P]rotectionism didn’t cause the Great Depression. It was a consequence, not a cause – and much less severe in countries that had the good sense to leave the gold standard.

That’s basically right. But I note for the record, to spell out the my point made in the post I alluded to in the opening paragraph that protectionism might indeed have played a role in exacerbating the Great Depression, making it harder for Germany and other indebted countries to pay off their debts by making it more difficult for them to exports required to discharge their obligations, thereby making their IOUs, widely held by European and American banks, worthless or nearly so, undermining the solvency of many of those banks. It also increased the demand for the gold required to discharge debts, adding to the deflationary forces that had been unleashed by the Bank of France and the Fed, thereby triggering the debt-deflation mechanism described by Irving Fisher in his famous article.

Which brings us to Cruz, who is enthusiastic about the gold standard – which did play a major role in spreading the Depression.

Well, that’s half — or maybe a quarter — right. The gold standard did play a major role in spreading the Depression. But the role was not just major; it was dominant. And the role of the gold standard in the Great Depression was not just to spread it; the role was, as Hawtrey and Cassel warned a decade before it happened, to cause it. The causal mechanism was that in restoring the gold standard, the various central banks linking their currencies to gold would increase their demands for gold reserves so substantially that the value of gold would rise back to its value before World War I, which was about double what it was after the war. It was to avoid such a catastrophic increase in the value of gold that Hawtrey drafted the resolutions adopted at the 1922 Genoa monetary conference calling for central-bank cooperation to minimize the increase in the monetary demand for gold associated with restoring the gold standard. Unfortunately, when France officially restored the gold standard in 1928, it went on a gold-buying spree, joined in by the Fed in 1929 when it raised interest rates to suppress Wall Street stock speculation. The huge accumulation of gold by France and the US in 1929 led directly to the deflation that started in the second half of 1929, which continued unabated till 1933. The Great Depression was caused by a 50% increase in the value of gold that was the direct result of the restoration of the gold standard. In principle, if the Genoa Resolutions had been followed, the restoration of the gold standard could have been accomplished with no increase in the value of gold. But, obviously, the gold standard was a catastrophe waiting to happen.

The problem with gold is, first of all, that it removes flexibility. Given an adverse shock to demand, it rules out any offsetting loosening of monetary policy.

That’s not quite right; the problem with gold is, first of all, that it does not guarantee that value of gold will be stable. The problem is exacerbated when central banks hold substantial gold reserves, which means that significant changes in the demand of central banks for gold reserves can have dramatic repercussions on the value of gold. Far from being a guarantee of price stability, the gold standard can be the source of price-level instability, depending on the policies adopted by individual central banks. The Great Depression was not caused by an adverse shock to demand; it was caused by a policy-induced shock to the value of gold. There was nothing inherent in the gold standard that would have prevented a loosening of monetary policy – a decline in the gold reserves held by central banks – to reverse the deflationary effects of the rapid accumulation of gold reserves, but, the insane Bank of France was not inclined to reverse its policy, perversely viewing the increase in its gold reserves as evidence of the success of its catastrophic policy. However, once some central banks are accumulating gold reserves, other central banks inevitably feel that they must take steps to at least maintain their current levels of reserves, lest markets begin to lose confidence that convertibility into gold will be preserved. Bad policy tends to spread. Krugman seems to have this possibility in mind when he continues:

Worse, relying on gold can easily have the effect of forcing a tightening of monetary policy at precisely the wrong moment. In a crisis, people get worried about banks and seek cash, increasing the demand for the monetary base – but you can’t expand the monetary base to meet this demand, because it’s tied to gold.

But Krugman is being a little sloppy here. If the demand for the monetary base – meaning, presumably, currency plus reserves at the central bank — is increasing, then the public simply wants to increase their holdings of currency, not spend the added holdings. So what stops the the central bank accommodate that demand? Krugman says that “it” – meaning, presumably, the monetary base – is tied to gold. What does it mean for the monetary base to be “tied” to gold? Under the gold standard, the “tie” to gold is a promise to convert the monetary base, on demand, at a specified conversion rate.

Question: why would that promise to convert have prevented the central bank from increasing the monetary base? Answer: it would not and did not. Since, by assumption, the public is demanding more currency to hold, there is no reason why the central bank could not safely accommodate that demand. Of course, there would be a problem if the public feared that the central bank might not continue to honor its convertibility commitment and that the price of gold would rise. Then there would be an internal drain on the central bank’s gold reserves. But that is not — or doesn’t seem to be — the case that Krugman has in mind. Rather, what he seems to mean is that the quantity of base money is limited by a reserve ratio between the gold reserves held by the central bank and the monetary base. But if the tie between the monetary base and gold that Krugman is referring to is a legal reserve requirement, then he is confusing the legal reserve requirement with the gold standard, and the two are simply not the same, it being entirely possible, and actually desirable, for the gold standard to function with no legal reserve requirement – certainly not a marginal reserve requirement.

On top of that, a slump drives interest rates down, increasing the demand for real assets perceived as safe — like gold — which is why gold prices rose after the 2008 crisis. But if you’re on a gold standard, nominal gold prices can’t rise; the only way real prices can rise is a fall in the prices of everything else. Hello, deflation!

Note the implicit assumption here: that the slump just happens for some unknown reason. I don’t deny that such events are possible, but in the context of this discussion about the gold standard and its destabilizing properties, the historically relevant scenario is when the slump occurred because of a deliberate decision to raise interest rates, as the Fed did in 1929 to suppress stock-market speculation and as the Bank of England did for most of the 1920s, to restore and maintain the prewar sterling parity against the dollar. Under those circumstances, it was the increase in the interest rate set by the central bank that amounted to an increase in the monetary demand for gold which is what caused gold appreciation and deflation.

Once Upon a Time When Keynes Endorsed the Fisher Effect

One of the great puzzles of the General Theory is Keynes’s rejection of the Fisher Effect on pp. 141-42. What is even more difficult to understand than Keynes’s criticism of the Fisher Effect, which I hope to parse in a future post, is that in his Tract on Monetary Reform Keynes had himself reproduced the Fisher Effect, though without crediting the idea to Fisher. Interestingly enough, when he turned against the Fisher Effect in the General Theory, dismissing it almost contemptuously, he explicitly attributed the idea to Fisher.

But here are a couple of quotations from the Tract in which Keynes exactly follows the Fisherian analysis. There are probably other places in which he does so as well, but these two examples seemed the most explicit. Keynes actually cites Fisher several times in the Tract, but those citations are to Fisher’s purely monetary work, in particular The Purchasing Power of Money (1911) which Keynes had reviewed in the Economic Journal. Of course, the distinction between the real and money rates of interest that Fisher made famous was not discovered by Fisher. Marshall had mentioned it and the idea was discussed at length by Henry Thornton, and possibly by other classical economists as well, so Keynes was not necessarily committing a scholarly offense by not mentioning Fisher. Nevertheless, it was Fisher who derived the relationship as a formal theorem, and the idea was already widely associated with him. And, of course, when Keynes criticized the idea, he explicitly attributed the idea to Fisher.

Economists draw an instructive distinction between what are termed the “money” rate of interest and the “real” rate of interest. If a sum of money worth 100 in terms of commodities at the time when the loan is made is lent for a year at 5 per cent interest, and is worth only 90 in terms of commodities at the end of the year, the lender receives back, including interest, what is worth only 94.5. This is expressed by saying that while the money rate of interest was 5 per cent, the real rate of interest had actually been negative and equal to minus 5.5 per cent. . . .

Thus, when prices are rising, the business man who borrows money is able to repay the lender with what, in terms of real value, not only represents no interest, but is even less than the capital originally advanced; that is the borrower reaps a corresponding benefit. It is true that , in so far as a rise in prices is foreseen, attempts to get advantage from this by increased borrowing force the money rates of interest to move upwards. It is for this reason, amongst others, that a high bank rate should be associated with a period of rising prices, and a low bank rate with a period of faling prices. The apparent abnormality of the money rate of interest at such times is merely the other side of the attempt of the real rate of interest to steady itself. Nevertheless in a period of rapidly changing prices, the money rate of interest seldom adjusts itself adequately or fast enough to prevent the real rate from becoming abnormal. For it is not the fact of a given rise of prices, but the expectation of a rise compounded of the various possible price movements and the estimated probability of each, which affects money rates. (pp. 20-22)

Like Fisher, Keynes, allowed for the possibility that inflation will not be fully anticipated so that the rise in the nominal rate will not fully compensate for the effect of inflation, suggesting that it is generally unlikely that inflation will be fully anticipated so that, in practice, inflation tends to reduce the real rate of interest. So Keynes seems fully on board with Fisher in the Tract.

Then there is Keynes’s celebrated theorem of covered interest arbitrage, perhaps his most important and enduring contribution to economics before writing the General Theory. He demonstrates the theorem in chapter 3 of the Tract.

If dollars one month forward are quoted cheaper than spot dollars to a London buyer in terms of sterling, this indicates a preference by the market, on balance, in favour of holding funds in New York during the month in question rather than in London – a preference the degree of which is measured by the discount on forward dollars. For if spot dollars are worth $4.40 to the pound and dollars one month forward $4.405 to the pound, then the owner of $4.40 can, by selling the dollars spot and buying them back one month forward, find himself at the end of the month with $4.405, merely by being during the month the owner of £1 in London instead of $4.40 in New York. That he should require and can obtain half a cent, which, earned in one month, is equal to about 1.5 per cent per annum, to induce him to do the transaction, shows, and is, under conditions of competition, a measure of, the market’s preference for holding funds during the month in question in New York rather than in London. . . .

The difference between the spot and forward rates is, therefore, precisely and exactly the measure of the preference of the money and exchange market for holding funds in one international centre rather than in another, the exchange risk apart, that is to say under conditions in which the exchange risk is covered. What is it that determines these preferences?

1. The most fundamental cause is to be found in the interest rates obtainable on “short” money – that is to say, on money lent or deposited for short periods of time in the money markets of the two centres under consideration. If by lending dollars in New York for one month the lender could earn interest at the rate of 5.5 per cent per annum, whereas by lending sterling in London for one month he could only earn interest at the rate of 4 per cent, then the preference observed above for holding funds in New York rather than London is wholly explained. That is to say, the forward quotations for the purchase of the currency of the dearer money market tend to be cheaper than spot quotations by a percentage per month equal to the excess of the interest which can be earned in a month in the dearer market over what can be earned in the cheaper. (pp. 123-34)

Compare Keynes’s discussion in the Tract to Fisher’s discussion in Appreciation and Interest, written over a quarter of a century before the Tract.

Suppose gold is to appreciate relatively to wheat a certain known amount in one year. What will be the relation between the rates of interest in the two standards? Let wheat fall in gold price (or gold rise in wheat price) so that the quantity of gold which would buy one bushel of wheat at the beginning of the year will buy 1 + a bushels at the end, a being therefore the rate of appreciation of gold in terms of wheat. Let the rate of interest in gold be i, and in wheat be j, and let the principal of the loan be D dollars or its equivalent B bushels. Our alternative contracts are then:

For D dollars borrowed D + Di or D(1 + i) dollars are due in one yr.

For B bushels     “       B + Bj or B(1 + j) bushels  ”   “    “   “   “

and our problem is to find the relation between i and j, which will make the D(1 + i) dollars equal the B(1 + j) bushels.

At first, D dollars equals B bushels.

At the end of the year D dollars equals B(1 + a) bushels

Hence at the end of one year D(1 + i) dollars equals B(1 + a) (1 + i) bushels

Since D(1 + i) dollars is the number of dollars necessary to liquidate the debt, its equivalent B(1 + a) (1 + i) bushels is the number of bushels necessary to liquidate it. But we have already designated this number of bushels by B(1 + j). Our result, therefore, is:

At the end of 1 year D(1 + i) dollars equals B(1 + j) equals B(1 + a) (1 + i) bushels

which, after B is canceled, discloses the formula:

1 + j = (1 + a) (1 + i)

Or,

j = i + a + ia

Or, in words: The rate of interest in the (relatively) depreciating standard is equal to the sum of three terms, viz., the rate of interest in the appreciating standard, the rate of appreciation itself and the product of these two elements. (pp. 8-9)

So, it’s clear that Keynes’s theorem of covered interest arbitrage in the Tract is a straightforward application of Fisher’s analysis in Appreciation and Interest. Now it is quite possible that Keynes was unaware of Fisher’s analysis in Appreciation and Interest, though it was reproduced in Fisher’s better known 1907 classic The Rate of Interest, so that Keynes’s covered-interest-arbitrage theorem may have been subjectively original, even though it had been anticipated in its essentials a quarter of a century earlier by Fisher. Nevertheless, Keynes’s failure to acknowledge, when he criticized the Fisher effect in the General Theory, how profoundly indebted he had been, in his own celebrated work on the foreign-exchange markets, to the Fisherian analysis was a serious lapse in scholarship, if not in scholarly ethics.

Hawtrey’s Good and Bad Trade: Part II

Published September 24, 2013 Hawtrey , James Tobin , John Fullarton , Knut Wicksell , monetary theory , natural rate of interest 21 Comments
Tags: , ,

Here I am again back at you finally with another installment in my series on Hawtrey’s Good and Bad Trade. In my first installment I provided some background on Hawtrey and a quick overview of the book, including a mention of the interesting fact (brought to my attention by David Laidler) that Hawtrey used the term “effective demand” in pretty much the same way that Keynes, some 20 years later, would use it in the General Theory.

In this post, I want to discuss what I consider the highlights of the first six chapters. The first chapter is a general introduction to the entire volume laying out the basic premise of the book, which is that the business cycle, understood as recurring fluctuations in the level of employment, is the result of monetary disturbances that lead to alternating phases of expansion and contraction. It is relatively easy for workers to find employment in expansions, but more difficult to do so in contractions. From the standpoint of the theory of economic equilibrium, the close correlation between employment and nominal income over the business cycle is somewhat paradoxical, because, according to the equilibrium theory, the allocation of resources is governed by relative, not absolute, prices. In the theory of equilibrium, a proportional increase or decrease in all prices should have no effect on employment. To explain the paradox, Hawtrey relies on the rigidity of some prices, and especially wages, an empirical fact that, Hawtrey believed, was an essential aspect of any economic system, and a necessary condition for the cyclicality of output and employment.

In Hawtrey’s view, economic expansions and contractions are caused by variations in effective demand, which he defines as total money income. (For reasons I discussed about a year and a half ago, I prefer to define “effective demand” as total money expenditure.) What determines effective demand, according to Hawtrey, is the relationship between the amount of money people are holding and the amount that they would, on average over time, like to hold. The way to think about the amount of money that people would like to hold is to imagine that there is some proportion of their annual income that people aim to hold in the form of cash.

The relationship between the amount of cash being held and the amount that people would like to hold depends on the nature of the monetary system. Hawtrey considers two types of monetary system: one type (discussed in chapter 2) is a pure fiat money system in which all money is issued by government; the other (discussed in chapter 3) is a credit system in which money is also created by banks by promising to redeem, on demand, their obligations (either deposits or negotiable banknotes) for fiat money. Credit money is issued by banks in exchange for a variety of assets, usually the untraded IOUs of borrowers.

In a pure fiat money system, effective demand depends chiefly on the amount of fiat money that people want to hold and on the amount of fiat money created by the government, fiat money being the only money available. A pure fiat money system, Hawtrey understood, was just the sort of system in which the propositions of the quantity theory of money would obtain at least in the medium to long run.

[I]f the adjustment [to a reduction in the quantity of money] could be made entirely by a suitable diminution of wages and salaries, accompanied by a corresponding diminution of prices, the commercial community could be placed forthwith in a new position of equilibrium, in which the output would continue unchanged, and distribution would only be modified by the apportionment of a somewhat larger share of the national product to the possessors of interest, rent, and other kinds of fixed incomes. In fact, the change in the circulating medium is merely a change in the machinery of distribution, and a change, moreover, which, once made, does not impair the effectiveness of that machinery. If the habits of the community are adapted without delay to the change, the production of wealth will continue unabated. If customary prices resist the change, the adjustment, which is bound to come sooner or later, will only be forced upon the people by the pressure of distress. (p. 41)

In a fiat money system, if the public have less money than they would like to hold their only recourse is to attempt to reduce their expenditures relative to their receipts, either offering more in exchange, which tends to depress prices or reducing their purchases, making it that much more difficult for anyone to increase sales except by reducing prices. The problem is that in a fiat system the amount of money is what it is, so that if one person manages to increase his holdings of money by increasing sales relative to purchases, his increase in cash balances must have be gained at the expense of someone else. With a fixed amount of fiat money in existence, the public as a whole cannot increase their holdings of cash, so equilibrium can be restored only by reducing the quantity of money demanded. But the reduction in the amount of money that people want to hold cannot occur unless income in money terms goes down. Money income can go down only if total output in real terms, or if the price level, falls. With nominal income down, people, wanting to hold some particular share of their nominal income in the form of money, will be content with a smaller cash balance than they were before, and will stop trying to increase their cash balances by cutting their expenditure. Because some prices — and especially wages — tend to be sticky, Hawtrey felt that it was inevitable that the adjustment to reduction in the amount of fiat money would cause both real income and prices to fall.

Although Hawtrey correctly perceived that the simple quantity theory would not, even in theory, hold precisely for a credit system, his analysis of the credit system was incomplete inasmuch as he did not fully take into account the factors governing the public’s choice between holding credit money as opposed to fiat money or the incentives of the banking system to create credit money. That theory was not worked out till James Tobin did so 50 years later (another important anniversary worthy of note), though John Fullarton made an impressive start in his great work on the subject in 1844, a work Hawtrey must have been familiar with, but, to my knowledge, never discussed in detail.

In such a banking system there is no necessary connexion between the total of the deposits and the amount of coin which has been paid to the banks. A banker may at any time grant a customer a loan by simply adding to the balance standing to the customer’s credit in the books of the bank. No cash passes, but the customer acquires the right, during the currency of the loan, to draw cheques on the bank up to the amount lent. When the period of the loan expires, if the customer has a large enough balance to his credit, the loan can be repaid without any cash being employed, the amount of the loan being simply deducted from the balance. So long as the loan is outstanding it represents a clear addition to the available stock of “money,” in the sense of purchasing power. It is “money” in the the sense which will play, in a community possessing banks, the same part as money in the stricter sense of legal tender currency would play in the fictitious bankless community whose commercial conditions we previously have been considering. This is the most distinctive feature of the banking system, that between the stock of legal tender currency and the trading community there is interposed an intermediary, the banker, who can, if he wishes, create money out of nothing. (PP. 56-57)

This formulation is incomplete, inasmuch as it leaves the decision of the banker about how much money to create unconstrained by the usual forces of marginal revenue and marginal cost that supposedly determine the decisions of other profit-seeking businessmen. Hawtrey is not oblivious to the problem, but does not advance the analysis as far as he might have.

We have now to find out how this functionary uses his power and under what limitations he works. Something has already been said of the contingencies for which he must provide. Whenever he grants a loan and thereby creates money, he must expect a certain portion of this money to be applied sooner or later, to purposes for which legal tender currency is necessary. Sums will be drawn out from time to time to be spent either in wages or in small purchases, and the currency so applied will take a little time to find its way back to the banks. Large purchases will be paid for by cheque, involving a mere transfer of credit from one banking account to another, but the recipient of the cheque may wish to apply it ot the payment of wages, etc. Thus the principal limitation upon the banker’s freedom to create money is that he must have a reserve to meet the fresh demands for cash to which the creation of new money may lead. (Id.)

This is a very narrow view, apparently assuming that there is but one banker and that the only drain on the reserves of the banker is the withdrawal of currency by depositors. The possibility that recipients of cheques drawn on one bank may prefer to hold those funds in a different bank so that the bank must pay a competitive rate of interest on its deposits to induce its deposits to be held rather than those of another bank is not considered.

In trade a seller encourages or discourages buyers by lowering or raising his prices. So a banker encourages or discourages borrowers by lowering or raising the rate of interest. (p.58)

Again, Hawtrey only saw half the picture. The banker is setting two rates: the rate that he charges borrowers and the rate that he pays to depositors. It is the spread between those two rates that determines the marginal revenue from creating another dollar of deposits. Given that marginal revenue, the banker must form some estimate of the likely cost associated with creating another dollar of deposits (an estimate that depends to a large degree on expectations that may or may not be turn out to be correct), and it is the comparison between the marginal revenue from creating additional deposits with the expected cost of creating additional deposits that determines whether a bank wants to expand or contract its deposits.

Of course, the incomplete analysis of the decision making of the banker is not just Hawtrey’s, it is characteristic of all Wicksellian natural-rate theories. However, in contrast to other versions of the natural-rate genre, Hawtrey managed to avoid the logical gap in those theories: the failure to see that it is the spread between the lending and the deposit rates, not the difference between the lending rate and the natural rate, that determines whether banks are trying to expand or contract. But that is a point that I will have to come back to in the next installment in this series in which I will try to follow through the main steps of Hawtrey’s argument about how a banking system adjusts to a reduction in the quantity of fiat money (aka legal tender currency or base money) is reduced. That analysis, which hinges on the role of merchants and traders whose holding of inventories of goods is financed by borrowing from the banks, was a critical intellectual innovation of Hawtrey’s and was the key to his avoidance of the Wicksellian explanatory gap.

Uneasy Money Marks the Centenary of Hawtrey’s Good and Bad Trade

Published September 10, 2013 David Laidler , Hawtrey , Keynes 9 Comments
Tags: , , ,

As promised, I am beginning a series of posts about R. G. Hawtrey’s book Good and Bad Trade, published 100 years ago in 1913. Good and Bad Trade was not only Hawtrey’s first book on economics, it was his first publication of any kind on economics, and only his second publication of any kind, the first having been an article on naval strategy written even before his arrival at Cambridge as an undergraduate. Perhaps on the strength of that youthful publication, Hawtrey’s first position, after having been accepted into the British Civil Service, was in the Admiralty, but he soon was transferred to the Treasury where he remained for over forty years till 1947.

Though he was a Cambridge man, Hawtrey had studied mathematics and philosophy at Cambridge. He was deeply influenced by the Cambridge philosopher G. E. Moore, an influence most clearly evident in one of Hawtrey’s few works of economics not primarily concerned with monetary theory, history or policy, The Economic Problem. Hawtrey’s mathematical interests led him to a correspondence with another Cambridge man, Bertrand Russell, which Russell refers to in his Principia Mathematica. However, Hawtrey seems to have had no contact with Alfred Marshall or any other Cambridge economist. Indeed, the only economist mentioned by Hawtrey in Good and Bad Trade was none other than Irving Fisher, whose distinction between the real and nominal rates of interest Hawtrey invokes in chapter 5. So Hawtrey was clearly an autodidact in economics. It is likely that Hawtrey’s self-education in economics started after his graduation from Cambridge when he was studying for the Civil Service entrance examination, but it seems likely that Hawtrey continued an intensive study of economics even afterwards, for although Hawtrey was not in the habit of engaging in lengthy discussions of earlier economists, his sophisticated familiarity with the history of economics and of economic history is quite unmistakable. Nevertheless, it is a puzzle that Hawtrey uses the term “natural rate of interest” to signify more or less the same idea that Wicksell had when he used the term, but without mentioning Wicksell.

In his introductory chapter, Hawtrey lays out the following objective:

My present purposed is to examine certain elements in the modern economic organization of the world, which appear to be intimately connected with [cyclical] fluctuations. I shall not attempt to work back from a precise statistical analysis of the fluctuations which the world has experienced to the causes of all the phenomena disclosed by such analysis. But I shall endeavor to show what the effects of certain assumed economic causes would be, and it will, I think, be found that these calculated effects correspond very closely with the observed features of the fluctuations.

The general result up to which I hope to work is that the fluctuations are due to disturbances in the available stock of “money” – the term “money” being take to cover every species of purchasing power available for immediate use, both legal tender money and credit money, whether in the form of coin, notes, or deposits at banks. (p. 3)

In the remainder of this post, I will present a quick overview of the entire book, and, then, as a kind of postscript to my earlier series of posts on Hawtrey and Keynes, I will comment on the fact that it seems quite clear that it was Hawtrey who invented the term “effective demand,” defining it in a way that does not appear significantly different from the meaning that Keynes attached to it.

Hawtrey posits that the chief problem associated with the business cycle is that workers are unable to earn an income with which to sustain themselves during business-cycle contractions. The source of this problem in Hawtrey’s view is some sort of malfunction in the monetary system, even though money, when considered from the point of view of an equilibrium, seems unimportant, inasmuch as any set of absolute prices would work just as well as another, provided that relative prices were consistent with equilibrium.

In chapter 2, Hawtrey explains the idea of a demand for money and how this demand for money, together with any fixed amount of inconvertible paper money will determine the absolute level of prices and the relationship between the total amount of money in nominal terms and the total amount of income.

In chapter 3, Hawtrey introduces the idea of credit money and banks, and the role of a central bank.

In chapter 4, Hawtrey discusses the organization of production, the accumulation of capital, and the employment of labor, explaining the matching circular flows: expenditure on goods and services, the output of goods and services, and the incomes accruing from that output.

Having laid the groundwork for his analysis, Hawtrey in chapter 5 provides an initial simplified analysis of the effects of a monetary disturbance in an isolated economy with no banking system.

Hawtrey continues the analysis in chapter 6 with a discussion of a monetary disturbance in an isolated economy with a banking system.

In chapter 7, Hawtrey discusses how a monetary disturbance might actually come about in an isolated community.

In chapter 8, Hawtrey extends the discussion of the previous three chapters to an open economy connected to an international system.

In chapter 9, Hawtrey drops the assumption of an inconvertible paper money and introduces an international metallic system (corresponding to the international gold standard then in operation).

Having completed his basic model of the business cycle, Hawtrey, in chapter 10, introduces other sources of change, e.g., population growth and technological progress, and changes in the supply of gold.

In chapter 11, Hawtrey drops the assumption of the previous chapters that there are no forces leading to change in relative prices among commodities.

In chapter 12, Hawtrey enters into a more detailed analysis of money, credit and banking, and, in chapter 13, he describes international differences in money and banking institutions.

In chapters 14 and 15, Hawtrey traces out the sources and effects of international cyclical disturbances.

In chapter 16, Hawtey considers financial crises and their relationship to cyclical phenomena.

In chapter 17, Hawtrey discusses banking and currency legislation and their effects on the business cycle.

Chapters 18 and 19 are devoted to taxation and public finance.

Finally in chapter 20, Hawtrey poses the question whether cyclical fluctuations can be prevented.

After my series on Hawtrey and Keynes, I condensed those posts into a paper which, after further revision, I hope will eventually appear in the forthcoming Elgar Companion to Keynes. After I sent it to David Laidler for comments, he pointed out to me that I had failed to note that it was actually Hawtrey who, in Good and Bad Trade, introduced the term “effective demand.”

The term makes its first appearance in chapter 1 (p. 4).

The producers of commodities depend, for their profits and for the means of paying wages and other expenses, upon the money which they receive for the finished commodities. They supply in response to a demand, but only to an effective demand. A want becomes an effective demand when the person who experiences the want possesses (and can spare) the purchasing power necessary ot meet the price of the thing which will satisfy it. A man may want a hat, but if he has no money [i.e., income or wealth] he cannot buy it, and his want does not contribute to the effective demand for hats.

Then at the outset of chapter 2 (p. 6), Hawtrey continues:

The total effective demand for all finished commodities in any community is simply the aggregate of all money incomes. The same aggregate represents also the total cost of production of all finished commodities.

Once again, Hawtrey, in chapter 4 (pp. 32-33), returns to the concept of effective demand

It was laid down that the total effective demand for all commodities si simply the aggregate of all incomes, and that the same aggregate represents the total cost of production of all commodities.

Hawtrey attributed fluctuations in employment to fluctuations in effective demand inasmuch as wages and prices would not adjust immediately to a change in total spending.

Here is how Keynes defines aggregate demand in the General Theory (p. 55)

[T]he effective demand is simply the aggregate income or (proceeds) which the entrepreneurs expect to receive, inclusive of the income which they will hand on to the other factors of production, from the amount of current employment which they decide to give. The aggregate demand function relates various hypothetical quantities of employment to the proceeds which their outputs are expected to yield; and the effective demand is the point on the aggregate demand function which becomes effective because, taken in conjunction with the conditions of supply, it corresponds to the level of employment which maximizes the entrepreneur’s expectation of profit.

So Keynes in the General Theory obviously presented an analytically more sophisticated version of the concept of effective demand than Hawtrey did over two decades earlier, having expressed the idea in terms of entrepreneurial expectations of income and expenditure and specifying a general functional relationship (aggregate demand) between employment and expected income. Nevertheless, the basic idea is still very close to Hawtrey’s. Interestingly, Hawtrey never asserted a claim of priority on the concept, whether it was because of his natural reticence or because he was unhappy with how Keynes made use of the idea, or perhaps some other reason, I would not venture to say. But perhaps others would like to weigh in with some speculations of their own.

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
