A Stable Price Level Standard for Federal Reserve Monetary Policy

In a recent article in the Cato Journal dealing with the transparency of Federal Reserve monetary policy, Federal Open Market Committee (FOMC) Chairman Ben Bernanke provided an authoritative account of current Federal Reserve strategy (Cato Journal, vol. 28, No. 2, Spring/​Summer, 2008, “The Fed’s Road Toward Greater Transparency,” pp. 175–186). Bernanke notes that “inflation‐​targeting” does not imply a single‐​minded focus on inflation, but includes a “dual mandate” that also takes “account of other economic goals besides price stability–notably economic growth, employment, and financial stability–when making policy decisions” (183). Central banks, Bernanke states, agree that “maintaining low and stable inflation” is the best means to maximize economic welfare.

Bernanke observes, however, that Congress has given the Fed “two objectives, maximum employment and price stability, [and the two are] on an equal footing.” He and the rest of the FOMC “strongly support the dual mandate.” He recognizes that the Fed’s “monetary policy determines the long‐​run inflation rate, whereas the factors that influence the sustainable rates of growth and employment are in the long run largely outside the central bank’s control” (184). The “diversity” of views on the FOMC “drives the Committee to adopt an eclectic approach and thus serves to limit the risk that a single viewpoint or analytical framework might become unduly dominant” (185).

Bernanke’s apologia for Fed policy is standard Fed boilerplate. It includes variables of both time–short-run and long-run–and goals–maximum employment and price level stability. Whether to concentrate on short‐​run real variables, of which there are multitudes in addition to “maximum” employment, or to promote the long‐​run stability of the price level, which is unequivocally a broad‐​based price index with zero change, requires their “eclectic” discretion. Bernanke acknowledges that price level stability, or any fixed rate of inflation or deflation, is the one goal that the Fed, and only the Fed, can achieve. But how can it or should it reconcile these short‐​run and long‐​run goals?

Long ago, in 1950, Senator Paul Douglas (D-Ill.)–on leave from the University of Chicago where he was a professor of economics–properly put the “short run” and the “long run” into proper perspective. In this instance, a Senate Committee Report had stated that “monetary policy was unimportant in the short run.” Douglas’s response pointed out what should be obvious: “[T]he long run … is made up of short runs. If it be assumed that monetary policy has no effect in each of a series of short‐​runs, then it can have no effect in the long run” (Patman Subcommittee Report. U.S. Congress, 1950). The same criterion applies to current Fed policy: If the Fed is to stabilize the dollar in the “long run,” it must do the same in a succession of short runs in order to achieve its long‐​run objective.

Since at least 1980, “price level stability,” as a major objective of Fed policy, has been prominent in the FOMC’s Policy Directive to the Fed Bank of New York. Indeed, in 1988 with Chairman Greenspan’s arrival on the scene, what had been phrased “reasonable price level stability” became just plain “price level stability,” with no “reasonable” qualification.

The government’s Consumer Price Index (CPI) shows price level increases over this period. For 1980, the CPI was 86 (1982–84=100). By 2007, it was 211, which means that prices were almost 2 1/2 times in 2007 what they were in 1980. Therefore, the value of the dollar, being the reciprocal of “all prices,” declined from 100 to 41. Is this result–a 59 percent reduction in the value of the money unit–“long-run price stability”? Is the value of the dollar “stabilized” when it loses three‐​fifths of its value every 20 to 25 years? Clearly not.

And what has been the payoff‐​the offsetting gain‐​for such mismanagement of the dollar’s value? Were business fluctuations any less severe? Or were the departures from zero inflation simply results of political pressure “to do something” for special interest groups, such as, financial mega firms, or the Freddies and Fannies?

Bernanke’s explanation of Fed policy reminds one of the epigram of the ancient Greek philosopher Archilochus, authoritatively translated by Guy Davenport as, “The fox knows many tricks, and still gets caught. The hedgehog knows one big trick [namely, how to survive enemy attacks by curling into a spiky ball] but it always works.” The crafty Federal Reserve fox knows a lot of tricks — how to bail out banks, how to lower interest rates, how to arrange swaps of securities, and all the legerdemain of finance, plus explanations of how to alleviate short‐​run cyclical slumps that seem to make its operations acceptable. In attempting to practice these tricks, however, the Fed fox often finds itself generating 2‐​to5 percent inflation, while achieving nothing of any permanent value for the private sector.

The single‐​minded Fed hedgehog, by contrast, knows the One Big Trick it always has the power to carry off: Control the nominal stock of money to maintain a stable price level. When it does so, it thereby keeps the value of the money‐​unit (the dollar) constant so that markets function with their maximum efficiency. For which role is the Fed better fitted?

Circumstances and political reality answer this question. The Fed cannot be a crafty fox that does a lot of desirable things. It cannot control interest rates. It has only an ephemeral effect on a few short‐​term interest rates as artifacts of the means by which it controls the stock of money. It cannot create anything real. But it can do One Big Thing extremely well: Maintain absolute stability in the average of money prices by its control over the nominal stock of dollars that it provides to the U.S. economy and the world. With this device, the Fed can generate any rate of price‐​level change that Bernanke and the FOMC chooses. If it irresponsibly ignores this talent and initiates its other temptations, it necessarily sacrifices price level stability. Not even a crafty fox can catch two rabbits at the same time.

With its power over the nominal quantity of money the Fed can maintain any rate of price level change from less‐​than‐​zero to infinity (hyperinflation). The proper rate of change for a number of good reasons, however, is ZERO.

  1. Only zero inflation provides absolute price stability. By contrast, any non‐​zero inflation rate, no matter how small, continually erodes the value of the dollar. Even with an inflation rate of “only” two percent, the dollar loses 50 percent of its real value every 35 years, and all interest rates are constantly two percent higher than they would otherwise be.

  2. Everyone understands zero inflation, whereas even a “low,” non‐​zero inflation target is vague and uncertain as it can only promise “near‐​price stability.” An inflation rate of 10 percent per year is “nearer” price stability than an inflation rate of 15 percent. Only zero is unequivocal.

  3. Zero inflation requires the Fed to correct occasional inflationary mistakes with equal and opposite amounts of deflation. Consequently, with the commitment to price level stability, the FOMC would immediately correct all vagrant price level variations before they became large enough to be a problem.

  4. Zero inflation provides the standard monetary unit with the same constancy required of all standard weights and measures, and is implied by the U.S. Constitution, Article 1, Section 8. Non‐​zero inflation rates, by contrast, render the monetary standard elastic, similar to a stretchable yardstick, variable ton, or shrinkable mile, and not even constancy in the variation.

  5. Zero inflation eliminates the confusion and misunderstanding between relative and absolute price changes that keep markets from operating at peak efficiency. With a stable price level, all dollar price changes are also changes in real values.

  6. Finally, explicit FOMC adherence to a stable price level, i.e., zero inflation, i.e., a constant‐​value dollar, is an effective buffer against political encroachments. If Fed spokesmen, such as Bernanke, emphasize that zero inflation is the stratagem and that nothing any good can be achieved by breaching it, they have an effective and valid defense against political pressures to “ease up,” or “lower interest rates.” This defense is especially valuable now, and may become even more pertinent in a few years when some future administration “asks” the Fed to buy new Treasury securities to fund Social Security and Medicare payments. Without some formal devise to counteract an ambitious or threatened Administration and its penchant for “lower interest rates,” the Fed could easily cave in. One can only shudder at the potential hyperinflation waiting in the wings under such circumstances: Nine trillion dollars of government securities waiting to be monetized.

A monetary standard has been missing in the United States since the formal abandonment of gold in 1971. Under the working gold standard throughout the nineteenth century and up to World War I, the world‐​gold‐​value of goods determined all money prices. World prices were astonishingly stable, even though all relative prices could fluctuate in accordance with real demands and real supplies. After the United States went off the gold standard, however, the FOMC, buffeted by the political forces in Washington, has determined monetary policy. The long‐​run result has been ninety‐​five years of various rates of inflation, and a dollar that has lost ninety percent of its purchasing power since the Fed came into existence in 1913.

Congress has the power and the responsibility to specify a Stable Price Level Standard for the U.S. monetary system. To implement this new standard, either the FOMC would apply it operationally, or Congress would formally charge the Fed to deliver a zero rate of inflation as measured by a comprehensive price index from quarter to quarter. This move would effectively substitute a new price level standard for the old gold standard. The Fed would necessarily have the crucial role of maintaining that standard, and would have every incentive to do so. It would, of course, have to tell political pressure groups that it was a “hedgehog” and not a “fox.” But at least it would be a very good hedgehog.
