This article is excerpted from America's Great Depression, part 2, chapter 6, "Theory and Inflation: Economists and the Lure of a Stable Price Level" (1963; 2008).

One of the reasons that most economists of the 1920s did not recognize the existence of an inflationary problem was the widespread adoption of a stable price level as the goal and criterion for monetary policy. The extent to which the Federal Reserve authorities were guided by a desire to keep the price level stable has been a matter of considerable controversy. Far less controversial is the fact that more and more economists came to consider a stable price level as the major goal of monetary policy. The fact that general prices were more or less stable during the 1920s told most economists that there was no inflationary threat, and therefore the events of the Great Depression caught them completely unaware.

Actually, bank-credit expansion creates its mischievous effects by distorting price relations and by raising and altering prices compared to what they would have been without the expansion. Statistically, therefore, we can only identify the increase in money supply, a simple fact. We cannot prove inflation by pointing to price increases. We can only approximate explanations of complex price movements by engaging in a comprehensive economic history of an era — a task which is beyond the scope of this study. Suffice it to say here that the stability of wholesale prices in the 1920s was the result of monetary inflation offset by increased productivity, which lowered costs of production and increased the supply of goods.

But this "offset" was only statistical. It did not eliminate the boom-bust cycle; it only obscured it. The economists who emphasized the importance of a stable price level were thus especially deceived, for they should have concentrated on what was happening to the supply of money. Consequently, the economists who raised an alarm over inflation in the 1920s were largely the qualitativists. They were written off as hopelessly old-fashioned by the "newer" economists who realized the overriding importance of the quantitative in monetary affairs. The trouble did not lie with particular credit on particular markets (such as stock or real estate); the boom in the stock and real-estate markets reflected Mises's trade cycle: a disproportionate boom in the prices of titles to capital goods, caused by the increase in money supply attendant upon bank credit expansion.1

The stability of the price level in the 1920s is demonstrated by the Bureau of Labor Statistics Index of Wholesale Prices, which fell to 93.4 (100 = 1926) in June 1921, rose slightly to a peak of 104.5 in November 1925, and then fell back to 95.2 by June 1929. The price level, in short, rose slightly until 1925 and fell slightly thereafter. Consumer price indices also behaved in a similar manner.2 On the other hand, the Snyder Index of the General Price Level, which includes all types of prices (real estate, stocks, rents, and wage rates, as well as wholesale prices) rose considerably during the period, from 158 in 1922 (1913 = 100) to 179 in 1929, a rise of 13 percent. Stability was therefore achieved only in consumer and wholesale prices, but these were and still are the fields considered especially important by most economic writers.

Within the overall aggregate of wholesale prices, foods and farm products rose over the period while metals, fuel, chemicals, and home furnishings fell considerably. That the boom was largely felt in the capital-goods industries can be seen by (a) the quadrupling of stock prices over the period, and by (b) the fact that durable goods and iron and steel production each increased by about 160 percent, while the production of non-durable goods (largely consumer goods) increased by only 60 percent.

In fact, production of such consumer items as manufactured foods and textile products increased by only 48 percent and 36 percent respectively, from 1921 to 1929. Another illustration of Mises's theory was that wages were bid up far more in the capital-goods industries. Overbidding of wage rates and other costs is a distinctive feature of Mises's analysis of capital-goods industries in the boom. Average hourly earnings, according to the Conference Board Index, rose in selected manufacturing industries from $.52 in July 1921 to $.59 in 1929, a 12 percent increase. Among this group, wage rates in consumer-goods industries such as boots and shoes remained constant; they rose 6 percent in furniture, less than 3 percent in meat packing, and 8 percent in hardware manufacturing. On the other hand, in such capital-goods industries as machines and machine tools, wage rates rose by 12 percent, and by 19 percent in lumber, 22 percent in chemicals, and 25 percent in iron and steel.

Federal Reserve credit expansion, then, whether so intended or not, managed to keep the price level stable in the face of increased productivity that would, in a free and unhampered market, have led to falling prices and a spread of increased living standards to everyone in the population. The inflation distorted the production structure and led to the ensuing depression-adjustment period. It also prevented the whole populace from enjoying the fruits of progress in lower prices and insured that only those enjoying higher monetary wages and incomes could benefit from the increased productivity.

There is much evidence for the charge of Phillips, McManus, and Nelson that "the end-result of what was probably the greatest price-level stabilization experiment in history proved to be, simply, the greatest depression."3 Benjamin Strong was apparently converted to a stable-price-level philosophy during 1922. On January 11, 1925, Strong privately wrote,

that it was my belief, and I thought it was shared by all others in the Federal Reserve System, that our whole policy in the future, as in the past, would be directed toward the stability of prices so far as it was possible for us to influence prices.4

When asked, in the Stabilization Hearings of 1927, whether the Federal Reserve Board could "stabilize the price level to a greater extent" than in the past, by open-market operations and other control devices, Governor Strong answered,

I personally think that the administration of the Federal Reserve System since the reaction of 1921 has been just as nearly directed as reasonable human wisdom could direct it toward that very object.5

It appears that Governor Strong had a major hand, in early 1928, in drafting the bill by Representative James G. Strong of Kansas (no relation) to compel the Federal Reserve System to promote a stable price level.6 Governor Strong was ill by this time and out of control of the system, but he wrote the final draft of the bill along with Representative Strong. In the company of the congressman and professor John R. Commons, one of the leading theoreticians of a stable price level, Strong discussed the bill with members of the Federal Reserve Board. When the Board disapproved, Strong felt bound, in his public statements, to go along with them.7

We must further note that Carl Snyder, a loyal and almost worshipful follower of Governor Strong, and head of the statistical department of the Federal Reserve Bank of New York, was a leading advocate of monetary and credit control by the Federal Reserve to stabilize the price level.8

Certainly, the leading British economists of the day firmly believed that the Federal Reserve was deliberately and successfully stabilizing the price level. John Maynard Keynes hailed "the successful management of the dollar by the Federal Reserve Board from 1923 to 1928" as a "triumph" for currency management. D.H. Robertson concluded in 1929 that "a monetary policy consciously aimed at keeping the general price level approximately stable … has apparently been followed with some success by the Federal Reserve Board in the United States since 1922."10 Whereas Keynes continued to hail the Reserve's policy a few years after the depression began, Robertson became critical,

Looking back … the great American "stabilization" of 1922–1929 was really a vast attempt to destabilize the value of money in terms of human effort by means of a colossal program of investment … which succeeded for a surprisingly long period, but which no human ingenuity could have managed to direct indefinitely on sound and balanced lines.10

The siren song of a stable price level had lured leading politicians, to say nothing of economists, as early as 1911. It was then that Professor Irving Fisher launched his career as head of the "stable money" movement in the United States. He quickly gained the adherence of leading statesmen and economists to a plan for an international commission to study the money and price problem.

Supporters included President William Howard Taft, Secretary of War Henry Stimson, Secretary of the Treasury Franklin MacVeagh, Governor Woodrow Wilson, Gifford Pinchot, seven senators, and economists Alfred Marshall, Francis Edgeworth, and John Maynard Keynes in England. President Taft sent a special message to Congress in February 1912, urging an appropriation for such an international conference. The message was written by Fisher, in collaboration with Assistant Secretary of State Huntington Wilson, a convert to stable money. The Senate passed the bill, but it died in the House. Woodrow Wilson expressed interest in the plan but dropped the idea in the press of other matters.

In the spring of 1918, a Committee on the Purchasing Power of Money of the American Economic Association endorsed the principle of stabilization. Though encountering banker opposition to his stable-money doctrine, led notably by A. Barton Hepburn of the Chase National Bank, Fisher began organizing the Stable Money League at the end of 1920, and established the League at the end of May 1921 — at the beginning of our inflationary era. Newton D. Baker, secretary of war under Wilson, and Professor James Harvey Rogers of Cornell were two of the early organizers.

Other prominent politicians and economists who played leading roles in the Stable Money League were Professor Jeremiah W. Jenks, its first president; Henry A. Wallace, editor of Wallace's Farmer, and later secretary of agriculture; John G. Winant, later governor of New Hampshire; Professor John R. Commons, its second president; George Eastman of the Eastman-Kodak family; Lyman J. Gage, formerly secretary of the Treasury; Samuel Gompers, president of the American Federation of Labor; Senator Carter Glass of Virginia; Thomas R. Marshall, vice president of the United States under Wilson; Representative Oscar W. Underwood; Malcolm C. Rorty; and economists Arthur Twining Hadley, Leonard P. Ayres, William T. Foster, David Friday, Edwin W. Kemmerer, Wesley C. Mitchell, Warren M. Persons, H. Parker Willis, Allyn A. Young, and Carl Snyder.

The ideal of a stable price level is relatively innocuous during a price rise when it can aid sound-money advocates in trying to check the boom; but it is highly mischievous when prices are tending to sag, and the stabilizationists call for inflation. And yet, stabilization is always a more popular rallying cry when prices are falling. The Stable Money League was founded in 1920–1921, when prices were falling during a depression. Soon, prices began to rise, and some conservatives began to see in the stable money movement a useful check against extreme inflationists. As a result, the league changed its name to the National Monetary Association in 1923, and its officers continued as before, with Professor Commons as president.

By 1925, the price level had reached its peak and begun to sag, and consequently the conservatives abandoned their support of the organization, which again changed its name to the Stable Money Association. Successive presidents of the new association were H. Parker Willis, John E. Rovensky, executive vice president of the Bank of America, Professor Kemmerer, and "Uncle" Frederic W. Delano. Other eminent leaders in the Stable Money Association were Professor Willford I. King; President Nicholas Murray Butler of Columbia University; John W. Davis, Democratic candidate for president in 1924; Charles G. Dawes, director of the Bureau of the Budget under Harding, and vice president under Coolidge; William Green, president of the American Federation of Labor; Charles Evans Hughes, secretary of state until 1925; Otto H. Kahn, investment banker; Frank O. Lowden, former Republican governor of Illinois; Elihu Root, former secretary of state and senator; James H. Rand Jr.; Norman Thomas, of the Socialist Party; Paul M. Warburg; and Owen D. Young. Enlisting from abroad came Charles Rist of the Bank of France; Eduard Benes of Czechoslovakia; Max Lazard of France; Emile Moreau of the Bank of France; Louis Rothschild of Austria; and Sir Arthur Balfour, Sir Henry Strakosch, Lord Melchett, and Sir Josiah Stamp of Great Britain.

Serving as honorary vice presidents of the association were the presidents of the following organizations: the American Association for Labor Legislation, American Bar Association, American Farm Bureau Federation, American Farm Economic Association, American Statistical Association, Brotherhood of Railroad Trainmen, National Association of Credit Men, National Consumers' League, National Education Association, American Council on Education, United Mine Workers of America, the National Grange, the Chicago Association of Commerce, the Merchants' Association of New York, and Bankers' Associations in 43 states and the District of Columbia.

Executive director and operating head of the association with such formidable backing was Norman Lombard, brought in by Fisher in 1926. The association spread its gospel far and wide. It was helped by the publicity given to Thomas Edison and Henry Ford's proposal for a "commodity dollar" in 1922 and 1923. Other prominent stabilizationists in this period were professors George F. Warren and Frank Pearson of Cornell, Royal Meeker, Hudson B. Hastings, Alvin Hansen, and Lionel D. Edie. In Europe, in addition to the above mentioned, advocates of stable money included: Professor Arthur C. Pigou, Ralph G. Hawtrey, J.R. Bellerby, R.A. Lehfeldt, G.M. Lewis, Sir Arthur Salter, Knut Wicksell, Gustav Cassel, Arthur Kitson, Sir Frederick Soddy, F.W. Pethick-Lawrence, Reginald McKenna, Sir Basil Blackett, and John Maynard Keynes. Keynes was particularly influential in his propaganda for a "managed currency" and a stabilized price level, as set forth in his Tract on Monetary Reform, published in 1923.

Ralph Hawtrey proved to be one of the evil geniuses of the 1920s. An influential economist in a land where economists have shaped policy far more influentially than in the United States, Hawtrey, director of financial studies at the British Treasury, advocated international credit control by central banks to achieve a stable price level as early as 1913. In 1919, Hawtrey was one of the first to call for the adoption of a gold-exchange standard by European countries, tying it in with international central-bank cooperation. Hawtrey was one of the prime European trumpeters of the prowess of Governor Benjamin Strong.

Writing in 1932, at a time when Robertson had come to realize the evils of stabilization, Hawtrey declared, "The American experiment in stabilization from 1922 to 1928 showed that an early treatment could check a tendency either to inflation or to depression.… The American experiment was a great advance upon the practice of the nineteenth century," when the trade cycle was accepted passively.11 When Governor Strong died, Hawtrey called the event "a disaster for the world."12 Finally, Hawtrey was the main inspiration for the stabilization resolutions of the Genoa Conference of 1922.

It was inevitable that this host of fashionable opinion should be translated into legislative pressure, if not legislative action. Rep. T. Alan Goldsborough of Maryland introduced a bill to "Stabilize the Purchasing Power of Money" in May 1922, essentially Professor Fisher's proposal, fed to Goldsborough by former Vice President Marshall. Witnesses for the bill were Professors Fisher, Rogers, King, and Kemmerer, but the bill was not reported out of committee. In early 1924, Goldsborough tried again, and Representative O.B. Burtness of North Dakota introduced another stabilization bill. Neither was reported out of committee.

The next major effort was a bill by Rep. James G. Strong of Kansas, introduced in January, 1926, under the urging of veteran stabilizationist George H. Shibley, who had been promoting the cause of stable prices since 1896. Rather than the earlier Fisher proposal for a "compensated dollar" to manipulate the price level, the Strong Bill would have compelled the Federal Reserve System to act directly to stabilize the price level. Hearings were held from March 1926 until February 1927. Testifying for the bill were Shibley, Fisher, Lombard, Dr. William T. Foster, Rogers, Bellerby, and Commons. Commons, Rep. Strong, and Governor Strong then rewrote the bill, as indicated above, and hearings were held on the second Strong Bill in the spring of 1928.

The high point of testimony for the second Strong Bill was that of Sweden's Professor Gustav Cassel, whose eminence packed the Congressional hearing room. Cassel had been promoting stabilization since 1903. The advice of this sage was that the government employ neither qualitative nor quantitative measures to check the boom, since these would lower the general price level. In a series of American lectures, Cassel also urged lower Fed reserve ratios, as well as worldwide central-bank cooperation to stabilize the price level.

The Strong Bill met the fate of its predecessors, and never left the committee. But the pressure exerted at the various hearings for these bills, as well as the weight of opinion and the views of Governor Strong, served to push the Federal Reserve authorities into trying to manipulate credit for purposes of price stabilization.

International pressure strengthened the drive for a stable price level. Official action began with the Genoa Conference, in the spring of 1922. This Conference was called by the League of Nations, at the initiative of Premier Lloyd George, who in turn was inspired by the dominant figure of Montagu Norman. The Financial Commission of the Conference adopted a set of resolutions which, as Fisher puts it, "have for years served as the potent armory for the advocates of stable money all over the world."13 The resolutions urged international central-bank collaboration to stabilize the world price level, and also suggested a gold-exchange standard.

On the Financial Commission were such stabilizationist stalwarts as Sir Basil Blackett, Professor Cassel, Dr. Vissering, and Sir Henry Strakosch.14 The League of Nations, indeed, was quickly taken over by the stabilizationists. The Financial Committee of the League was largely inspired and run by Governor Montagu Norman, working through two close associates, Sir Otto Niemeyer and Sir Henry Strakosch. Sir Henry was, as we have indicated, a prominent stabilizationist.15 Furthermore, Norman's chief adviser in international affairs, Sir Charles S. Addis, was also an ardent stablizationist.16

In 1921, a Joint Committee on Economic Crises was formed by the General Labour Conference, the International Labour Office (ILO) of the League of Nations, and the Financial Committee of the League. On this Joint Committee were three leading stabilizationists: Albert Thomas, Henri Fuss, and Major J.R. Bellerby. In 1923, Thomas's report warned that a fall in the price level "almost invariably" causes unemployment. Henri Fuss of the ILO propagandized for stable price levels in the International Labour Review in 1926.

The Joint Committee met in June 1925 to affirm the principles of the Genoa Conference. In the meanwhile, two private international organizations, the International Association for Labour Legislation and the International Association on Unemployment, held a joint International Congress on Social Policy, at Prague, in October 1924. The congress called for the general adoption of the principles of the Genoa Conference, by stabilizing the general price level. The International Association for Social Progress adopted a report at its Vienna meeting in September 1928 prepared by stabilizationist Max Lazard of the investment banking house of Lazard Frères in Paris, calling for price-level stability. The ILO followed suit in June 1929 terming falling prices a cause of unemployment. And, finally, the Economic Consultative Committee of the league endorsed the Genoa principles in the summer of 1928.

Just as Professors Cassel and Commons wanted no credit restraint at all in 1928 and 1929, so Representative Louis T. McFadden, powerful chairman of the House Banking and Currency Committee, exerted a similar though more powerful brand of pressure on the Federal Reserve authorities. On February 7, 1929, the day after the Federal Reserve Board's letter to the Federal Reserve Banks warning about stock-market speculation, Representative McFadden himself warned the House against an adverse business reaction from this move. He pointed out that there had been no rise in the commodity price level, so how could there be any danger of inflation? The Fed, he warned skittishly, should not concern itself with the stock market or security loans, lest it produce a general slump. Tighter money would make capital financing difficult, and, coupled with the resulting loss of confidence, would precipitate a depression.

In fact, McFadden declared that the Fed should be prepared to ease money rates as soon as any fall in prices or employment might appear.17 Other influential voices raised against any credit restriction were those of W.T. Foster and Waddill Catchings, leading stabilizationists and well known for their underconsumptionist theories. Catchings was a prominent investment banker (of Goldman, Sachs, and Co.), and iron and steel magnate, and both men were close to the Hoover administration. (As we shall see, their "plan" for curing unemployment was adopted, at one time, by Hoover.)

In April 1929 Foster and Catchings warned that any credit restriction would lower the price level and hurt business. The bull market, they assured the public — along with Fisher, Commons, and the rest — was grounded on a sure foundation of American confidence and growth.18 And the bull speculators, of course, echoed the cry that everyone should "invest in America." Anyone who criticized the boom was considered to be unpatriotic and "selling America short."

Cassel was typical of European opinion in insisting on even greater inflationary moves by the Federal Reserve System. Sir Ralph Hawtrey, visiting at Harvard during 1928–1929, spread the gospel of price-level stabilization to his American audience.19 Influential British Labourite Philip Snowden urged in 1927 that the United States join in a world plan for price stabilization, to prevent a prolonged price decline. The London Statist and the Nation (London) both bemoaned the Federal Reserve "deflation."

Perhaps most extreme was a wildly inflationist article by the respected economist Professor Allyn A. Young, an American then teaching at the University of London. Young, in January 1929, warned about the secular downward price trend, and urged all central banks not to "hoard" gold, to abandon their "high gold reserve-ratio fetish," and to inflate to a fare-thee-well. "Central banks of the world," he declared, "appear to be afraid of prosperity. So long as they are they will exert a retarding influence upon the growth of production."20

In an age of folly, Professor Young's article was perhaps the crowning pièce de résistance — much more censurable than the superficially more glaring errors of such economists as Irving Fisher and Charles A. Dice on the alleged "new era" prosperity of the stock market. Merely to extrapolate present stock market conditions is, after all, not nearly as reprehensible as considering deflation the main threat in the midst of a rampantly inflationary era. But such was the logical conclusion of the stabilizationist position.

We may conclude that the Federal Reserve authorities, in promulgating their inflationary policies, were motivated not only by the desire to help British inflation and to subsidize farmers but were also guided — or rather misguided — by the fashionable economic theory of a stable price level as the goal of monetary manipulation.21
