Meltzer and Saranna Robinson During her active career as a monetary economist and historian, Anna Schwartz returned to the history of monetary standards many times. In the famed A Monetary History of the United States, 1867-1960 (Friedman and Schwartz 1963), in her work as executive director of the 1981-82 U.S. Gold Commission (Commission on the Role of Gold in the Domestic and International Monetary Systems 1982), in her introduction to the National Bureau volume A Retrospective on the Classical Gold Standard, 1821-1931 (Bordo and Schwartz 1984), and in books and papers on British and U.S. monetary history before and after these volumes, she has both summarized past knowledge with careful attention to detail and added important pieces to our under- standing of the way monetary systems work in practice. One issue to which she and others have returned many times is the relative welfare gain or loss under alternative standards. Properly so; a main task of economic historians and empirical scientists is to test the predictions and implications of economic theory. Since theory does not give an unqualified prediction about the welfare benefits of different standards, evidence on the comparative performance under different standards is required to reach a judgment. Measures of economic welfare or welfare loss usually include the growth rate of aggregate or per capita (or per family) consumption or output, the rates of actual and unanticipated inflation, and the risks or Allan H. Meltzer is University Professor and John M. Olin Professor of Political Econ- omy and Public Policy, Carnegie Mellon University. Saranna Robinson is a graduate student in the School of Urban and Public Affairs, Carnegie Mellon University. The authors received helpful comments from Michael Bordo, Bennett McCallum, William Poole, Benjamin Friedman, and Anna Schwartz. 163 164 Allan H. MeltzedSaranna Robinson uncertainty that individuals bear. We use unanticipated variability of prices and output as measures of uncertainty and actual inflation as a measure of the deviation from the optimal rate of inflation. Eichengreen (1985,6 and 9) includes the stability of real and nominal exchange rates under the gold standard as one of the benefits of the standard. While the evidence of greater real exchange rate stability under fixed exchange rates seems clear-cut, the welfare implications are less clear. I Given the same policy rules and policy actions, greater stability of real ex- change rates under the gold standard may be achieved at the cost of greater variability in output or employment. This will be true if the alternative to exchange rate adjustment is adjustment of relative costs of production and relative prices when wages, costs of production, or some prices are slow to adjust. We, therefore, exclude exchange rate stability from the comparison and focus attention on the variability of unanticipated output, prices, inflalion, and the growth rate of output.2 The following section discusses previous findings about the stability of prices and output and the rates of inflation and growth. We then consider the comparative experience of the seven countries in our sample under the classical gold standard. Bretton Woods, and the fluc- tuating exchange rate regime. Like most previous comparisons, our first comparisons are based on actual values or their rates of change. The variability of unanticipated changes in prices and output under the three regimes is a more relevant measure of variability and uncertainty. We obtain measures of uncertainty about the levels and growth rates of output and prices using a multistate Kalman filter based on the work of Bomhoff (1983) and Kool (1983). Subsequent sections describe our procedures, present some estimates of comparative uncertainty, and consider the relation between shocks in Britain and the United States under the gold standard. A conclusion completes the paper. 4.1 Previous Evidence Bordo (1986) summarizes previous work on the stability of prices and output under the gold standard. For prices, there is strong evidence of reversion to a mean value. As is well known, the price level in most countries shows little trend under the gold standard if one chooses a period long enough for alternating periods of inflation and deflation to occur. This is true of the seven countries that we consider here; average rates of inflation under the classical gold standard range from 0.08 percent to 1. I percent.3 While the long-term stability of the price level under the gold standard is often commented on favorably, it is not clear that ex post stability is desirable independently of the way in which it is achieved. Alter- nating periods of persistent inflation followed by persistent deflation 165 Stability Under the Gold Standard in Practice do not have the same welfare implications as small, transitory fluctua- tions around a constant expected or average price leveL4 Long-term price stability achieved through canceling wartime inflations by severe postwar deflations imposes costs on consumers and producers, and particularly so, if the timing or magnitude of both the inflations and deflations is uncertain. A policy of maintaining expected stability of commodity prices, instead of stability of the nominal gold price, would have avoided postwar deflations by revaluing gold. In place of the long- term commitment to a fixed nominal exchange rate of domestic money for gold, countries could have made a commitment to a stable expected price level. Cooper (1982) computed the rates of price change in four countries using the wholesale price index numbers available for the period. Cooper includes the years 1816 to 1913 but, for much of this period, major coun- tries were not on the gold standard. We start the classical gold standard period in the 1870s when several countries chose to buy and sell gold at a fixed price, and we end the period in 1913, the last prewar year. Al- though many countries fixed their currencies to gold in the 1920s, the rules of the system differed and the commitment was weaker. Cooper’s data for the years 1873-96 and 1896- 1913 are shown in table 4.1. The cumulative movement in each period is relatively large, although the average annual rate of change in the first two periods is 2 or 3 percent. For comparison, we have included the percentage change in consumer prices for the same four countries during 1957-70, approx- imately the years that the Bretton Woods system had convertible cur- rencies. The comparison shows that while the average annual rates of change under the gold standard are similar (or lower) for some coun- tries, they are higher for others. The key difference between the price movements in the earlier and later periods is that there is no evidence of mean reversion in postwar data following Bretton Woods. Few would argue, however, that the deflations of 1920-21 or 1929-33, or the prior deflations in the nine- teenth century that contributed to the reversions, reduced welfare less than the inflation of the 1970s.

MeltzedSaranna Robinson A major, unresolved issue is the degree to which people could an- ticipate that inflation or deflation would occur. Bond yields are often taken as evidence of expected stability under the gold standard. Ma- caulay’s series on railroad bond yields declines during the deflation of the 1870s and 1880s but continues to decline until 1899 or 1901, after gold, money, and prices had started to rise. The Macaulay yields are higher during the deflation of the 1870s than at the start of World War I, despite nearly twenty years of inflation. Although other factors may have been at work, the raw data give no support to the proposition that bond yields are a summary measure of anticipated price move- ments under the gold standard. Rockoff (1984) presents some evidence suggesting that there was a basis for belief that prices would return to some mean value. His study considers the relation of gold mining and technological change in gold extraction to the relative price of gold. He concludes, tentatively, that many of the new gold discoveries and technical changes in methods of extraction were the result of an earlier rise in the relative price of gold. On his interpretation, long-term price movements for the period 1821 to 1914 appear to be the result of changes in demand along a relatively elastic long-run gold supply curve. Rockoff’s evidence suggests a long- term, gradual reversion of commodity prices operating on the relative price of gold and the supply of gold.5 This mechanism, relying on changes in the resources devoted to gold production and storage to maintain long-term price stability, is not clearly superior to other means of maintaining price stability. The fact that the mechanism operates with a lag of decades raises, again, the issue of whether it was antic- ipated in a sense relevant for people allocating wealth and choosing to consume or save at the time.

Restout Discussion Paper 2018-16 The Gold Standard and the Great Depression: a Dynamic General Equilibrium Model⇤ Luca Pensieroso† Romain Restout‡ December 3, 2018 Abstract Was the Gold Standard a major determinant of the onset and the protracted character of the the Great Depression of the 1930s in the United States and Worldwide? In this paper, we model the ‘Gold- Standard hypothesis’ in a dynamic general equilibrium framework. We show that encompassing the international and monetary dimen- sions of the Great Depression is important to understand what hap- pened in the 1930s, especially outside the United States. Contrary to what is often maintained in the literature, our results suggest that the vague of successive nominal exchange rate devaluations coupled with the monetary policy implemented in the United States did not act as a relief. On the contrary, they made the Depression worse.

  • The Great Depression: an Overview by David C
    Introduction The Great Depression: An Overview by David C. Wheelock Why should students learn about the Great Depression? Our grandparents and great-grandparents lived through these tough times, but you may think that you should focus on more recent episodes in Ameri- can life. In this essay, I hope to convince you that the Great Depression is worthy of your interest and deserves attention in economics, social studies and history courses. One reason to study the Great Depression is that it was by far the worst economic catastrophe of the 20th century and, perhaps, the worst in our nation’s history. Between 1929 and 1933, the quantity of goods and services produced in the United States fell by one-third, the unemployment rate soared to 25 percent of the labor force, the stock market lost 80 percent of its value and some 7,000 banks failed. At the store, the price of chicken fell from 38 cents a pound to 12 cents, the price of eggs dropped from 50 cents a dozen to just over 13 cents, and the price of gasoline fell from 10 cents a gallon to less than a nickel. Still, many families went hungry, and few could afford to own a car. Another reason to study the Great Depression is that the sheer magnitude of the economic collapse— and the fact that it involved every aspect of our economy and every region of our country—makes this event a great vehicle for teaching important economic concepts. You can learn about inflation and defla- tion, Gross Domestic Product (GDP), and unemployment by comparing the Depression with more recent experiences.

  • From Bimetallism to Monetarism: the Shifting Political Affiliation of the Quantity Theory*
    From Bimetallism to Monetarism: the Shifting Political Affiliation of the Quantity Theory* by David Laidler Abstract: The quantity theory of money was associated with the politics of the right in the ‘70s and ‘80s, but a century earlier, particularly in America, it had played an important part in the proposals of the Progressive left. These political associations are examined, and it is argued that a crucial factor in the quantity theory’s apparent migration from left to right was its newly-forged links to the case for monetary policy rules in the interwar years. It was also in the 1930s that the endogenous-money Banking School doctrines deployed by anti-quantity theorists during the monetarist controversy first became mainly associated with the case for discretionary policy, rather than with support for the gold- standard rule, as they had been in earlier times. More generally, shifting scientific opinion about the causes of the Great Depression moved the political centre of gravity of monetary economics to the left from the 1930s onwards, and then back towards the right beginning in the ‘60s, creating an illusion of movement on the quantity theory’s part. ___________________________ *The opening lecture delivered at the 2001 conference of the European History of Economic Thought Society, on “The Influence of Politics on Economic Thought”, held at the Technical University of Darmstadt. This lecture had its origins in an email correspondence with Robert Leeson about post-war Chicago economics, and why the quantity theory should be regarded as a right-wing doctrine. I am grateful to him for the intellectual stimulation, and to Perry Mehrling, Bill Robson, Rick Szostak and Michael Trautwein made many useful comments on an earlier draft.

  • Blast from the Past: Hayek, Gold, and Money
    Blast from the Past: Hayek, Gold, and Money Nikhil Sridhar Richard Salsman, Faculty Advisor 1 Acknowledgements I would like to thank Professor Richard Salsman for his invaluable guidance in the writing of this paper and his incredible mentorship throughout my undergraduate career. I would also like to express my gratitude George Selgin of the Cato Institute’s Center for Monetary and Financial Alternatives for recommending many of the sources used in this paper. Finally, there is little chance that this paper would have been completed without the endless debates on monetary economics with my dear friends Gaurav Sharma, Alexander Frumkin, and Aditya Paruchuri. 2 Abstract The resurgence of Austrian economics and the development of market monetarism as a school of thought since the Global Financial Crisis has brought NGDP targeting into the mainstream political economic discourse. This paper will discuss a close cousin of nominal income targeting, Hayek’s rule for monetary policy, and explore its relationship with the classical gold standard, as many advocates of a stable nominal income pathway have also expressed support for some form of a gold standard in the past. This paper offers a theoretical and historical exposition of Hayek’s rule and the classical gold standard before offering a comparative institutional analysis of these two monetary regimes with special consideration given to political economic considerations. 3 Table of Contents Introduction ....................................................................................................................................

  • The Gold Standard, Deflation and Fascism in Polanyi's Great
    The gold standard, deflation and fascism in Polanyi’s Great Transformation. A multidisciplinary analysis ERNESTO CLAR Introduction In 1944 Karl Polanyi published a work that would become a milestone in 20th-century social science, The Great Transformation. He was among the first to explain the economic and political catastrophe of the inter-war period as the final stage of a long-term process that reigned in Western Europe (and the United States) in the wake of the Napoleonic wars, market liberalism. Polanyi considered those ‘one hundred years’ to be a coherent period covering the rise and fall of 19th-century civilization. Polanyi characterized the 19th-century civilization that was destined to die with the Great Depression of the 20th century by four institutions: the balance-of-power system, the gold standard, the self-regulating market and the liberal state. Of these institutions, Polanyi asserts that the gold standard was the only one to survive both the Long Depression (previously known as the Great Depression) of 1873-1886 and the Great War. However, its ultimate failure delivered the death blow for market liberalism and, in some places, also swept liberal democracy away with it. The final part of Polanyi’s book gives a historical account of this process. However, early on in the book, Polanyi warns us that he is not conducting historical research: «what we are searching for is not a convincing sequence of outstanding events, but an explanation of their trend in terms of human institutions»1. This statement should be understood as a declaration of intent; Polanyi’s analysis was not limited to a single subject, such as history or economics, and he made this very clear by saying «we shall encroach upon the field of several disciplines in the pursuit of a single aim»2.

  • The Gold Standard Loses Luster
    The Gold Standard Loses Luster KEY POINTS The gold standard eliminated the need for a discretionary central bank to control the money supply. Even so, central banks were known to work around the “rules” of the gold standard according to their needs, and in the process undermined the standard’s credibility. The gold standard proved too inflexible during the crisis conditions that prevailed during World War I and the Great Depression. It was abandoned in stages around the globe thereafter, setting the stage for a new era in central banking. When Congress established the Federal Reserve Gold’s Heyday System in 1913, the concept of monetary policy as we understand it today did not exist. Here is how the gold standard is supposed to work: Governments define their currencies in terms of gold, Instead of central bankers actively influencing the level agree to freely exchange their currencies for gold at that of bank reserves in pursuit of low inflation and full official price, and allow the unfettered import and export employment, the job of keeping the money supply in of gold. Countries’ official gold prices then establish balance was left to the gold standard, a time-tested fixed exchange-rate parities among national currencies. system.

Bordo 1.1 Introduction What was the traditional approach to the gold standard? In this paper, I try to provide an answer to the question by examining the works of major writers on the subject since the eighteenth century. 1 The choice of writers and works surveyed is based on my judgment that the works encompassed a significant share ofthe content ofthe traditional approach and that the writers played a significant role in the history of economic thought. Six major themes formed the traditional approach, and five major schools of thought may be identified. 1.2 Major Themes in the Literature The first theme, which runs from Cantillon to present-day writers, was that gold (the precious metals) was an ideal monetary standard, domesti­ cally and internationally, because of its unique qualities both as a stan­ dard of value and a medium of exchange. A stable price level in the long run that an automatically operated gold standard produced, in line with the commodity theory of money, was invariably contrasted to the evils of inconvertible fiduciary money.

  • Who Anticipated the Great Depression? Gustav Cassel Versus Keynes and Hayek on the Interwar Gold Standard
    DOUGLAS A. IRWIN Who Anticipated the Great Depression? Gustav Cassel versus Keynes and Hayek on the Interwar Gold Standard The intellectual response to the Great Depression is often portrayed as a battle between the ideas of Friedrich Hayek and John Maynard Keynes. Yet both the Austrian and the Keynesian interpretations of the Depression were incomplete. Austrians could explain how a country might get into a depres- sion (bust following a credit-fueled investment boom) but not how to get out of one (liquidation). Keynesians could explain how a country might get out of a depression (government spending on public works) but not how it got into one (animal spirits). By contrast, the monetary approach of Gustav Cassel has been ignored. As early as 1920, Cassel warned that misman- agement of the gold standard could lead to a severe depression. Cassel not only explained how this could occur, but his explanation anticipates the way that scholars today describe how the Great Depression actually occurred. Unlike Keynes or Hayek, Cassel analyzed both how a country could get into a depression (deflation due to tight monetary policies) and how it could get out of one (monetary expansion). JEL codes: B22, B31, E32, E42, E58, F41 Keywords: Cassel, Keynes, Hayek, Great Depression, gold standard, depression, central banks, Keynesian, Austrian, monetarist. FROM THE VANTAGE POINT of early 1929, few economists be- lieved that the world economy would slip into the unprecedented catastrophe we now know as the Great Depression. The sharp deflation in prices between 1929 and 1932 was almost entirely unanticipated (Cecchetti 1992, Hamilton 1992, Evans and Wachtel 1993).1 And neither contemporary forecasters nor modern time-series I wish to thank David Laidler and three anonymous referees for very helpful comments.
