For Supply-Siders, Gold’s Market Value Is a Sensitive Indicator of Impending Changes in the Overall Price Level

Under the supply-siders’ preferred alternative, the Fed is obliged to target the price of a commodity, say gold, whose market value is believed to be a sensitive indicator of impending changes in the overall price level. For example, if the target price of gold is established at $400 per ounce and it starts to exhibit a tendency to decline below this level on the open market, it indicates to the Fed that there is a developing shortage of money and spending, which threatens to reduce prices throughout the economy. By purchasing gold or even Treasury securities from the public in exchange for newly-created dollars until the price of gold returns to its target level, the Fed automatically remedies the monetary shortage and thereby offsets the tendency of the price level to decline. On the other hand, a surfeit of cash balances in the economy [surfeit means an amount that is too large, or is more than is needed]   is indicated by upward pressure on the market price of gold. The Fed relieves this pressure by selling gold or securities to the public and, in the process, absorbs and extinguishes the excess dollars before the general price level can be driven up.

Irving Fisher Was the True Founder of Modern Macroeconomics with Its Aggregative Reasoning and Its Politically Managed Fiat Money

This new view culminated in the work of Irving Fisher, who in 1911 formalized the quantity theory in mathematical terms and proposed it as a formula for use by politicians and bureaucrats charged with the task of managing money in the interests of stability of the price level. Indeed, it was Fisher and not Keynes who was the true founder of modern macroeconomics with its aggregative reasoning and its central notion of politically managed fiat money. As the modern monetary theorist and historian of thought, Jürg Niehans wrote:

Fisher’s reformulation of the quantity theory of money … has successfully survived seventy-five years of monetary debate without a need for major revision; its analytical content is accepted today by economists of all persuasions, and in the present world of fiat money it is actually more relevant than it was in Fisher’s gold standard world.

Such was the state of monetary economics when Mises published his seminal work on The Theory of Money and Credit, in 1912. In writing this book, Mises achieved two aims. The first was to reconstruct monetary theory by integrating it with the subjective-value theory of price which had been developed by the early Austrian economists, most notably Carl Menger and Eugen Böhm-Bawerk. By doing this Mises was able to resolve the so-called “Austrian Circle,” according to which the value of money could not be explained in terms of marginal utility because any such explanation involved circular reasoning. It was this misconception that opened the door to Fisher’s analysis of money in terms of aggregative variables such as the national money supply, velocity of circulation of money, the average price level, and so on, eventually leading to the unquestioned predominance of the macroeconomic quantity theory of money.

The Bimetallistic Refinement of the Quantity Theory after 1870 Contributed to the Destruction of the Gold Standard

The proponents of the bimetallic standard argued for remonetization of silver on the grounds that this measure would increase the money supply and thus arrest the decline in prices under the monometallic gold standard that had begun in the late 1870s. The quantity theory of money was the foundation of the arguments put forward by the bimetallists. The theoretical counter-arguments of the advocates of the monometallic gold standard were completely inadequate to meet the challenge posed by the quantity theorists. They were based on the view that the costs of production of mining gold directly determined the price level, a distortion of classical monetary theory developed by Ricardo and the currency school. Paradoxically, although the gold standard remained intact, at least for the short run, the seeds for its eventual abolition had been sown because the classical sound money doctrine had been discredited among economists.

As David Laidler, a modern proponent of the quantity theory, commented:

[T]he refinement of the quantity theory after 1870 did not strengthen the intellectual foundations of the Gold Standard. On the contrary, it was an important element in bringing about its eventual destruction. . . . [T]he notion of a managed money, available to be deployed in the cause of macroeconomic stability and capable of producing a better economic environment than one tied to gold, was not an intellectual response to the monetary instability of the post-war period. The idea appeared in a variety of guises in the pre-war literature as a corollary of the quantity theory there expounded.

Thus by the end of the nineteenth century the view that money should ideally be “stable” in value had fully displaced the classical ideal of “sound” money, meaning a commodity chosen by the market whose value was strictly governed by market forces and immune to manipulation by governments.

For John Law, Money Is an “Instrument” That Is Deliberately Designed to Achieve the “Policy Goals” of Government Planners

In 1705, Law published his principal work on money, entitled Money and Trade Considered: With a Proposal for Supplying the Nation with Money. Law’s “proposal” was intended to provide his native Scotland with a plentiful supply of money endowed with a long-run stability of value. The institutional centerpiece envisioned in Law’s scheme resembles a modern central bank, empowered to supply paper fiat money via the purchases and sales of securities and other assets on the open market. Also strikingly modern are the theoretical propositions with which Law supports his policy goals and prescriptions.

Law initiates his monetary theorizing with two fundamental assumptions about the nature and function of money. The first is that if money is not exactly an original creation of political authority, it ideally functions as a tool to be molded and wielded by government. Law believes that the State, as incarnated in the King, is the de facto “owner” of the money supply and that it therefore possesses the right and the power to determine the composition and quantity of money in light of the “public interest.” Writes Law:

All the coin of the Kingdom belongs to the State, represented in France by the King: it belongs to him in precisely the same way as the high roads do, not that he may appropriate them as his own property, but in order to prevent others doing so; and as it is one of the rights of the King, and of the King alone, to make changes in the highways for the benefit of the public, of which he (or his officers) is the sole judge, so it is also one of his rights to change the gold or silver coin into other exchange tokens, of greater benefit to the public. . . .

Translating Law’s statement into modern terms, money is an “instrument” that is or should be deliberately designed to achieve the “policy goals” considered desirable by political money managers and other government planners.
