When we speak of the Federal Reserve as having responsibility for conducting monetary policy, we are talking specifically about its role in managing the nation's money supply. To do so, the Federal Reserve exercises its main monetary policymaking arm—the Federal Open Market Committee or FOMC—which meets eight times each year. After each meeting, the FOMC issues a directive, which contains instructions for policy until the next meeting. The Fed implements virtually all monetary policy decisions through the process of adding or removing reserves from the banking system at the open market desk of the Federal Reserve Bank of New York.
Ultimately, the goal of any economic policy is to achieve the highest standard of living possible for its citizens. The question is, how can the Fed most effectively contribute to this goal? The answer to this question has evolved over the years. The Humphrey-Hawkins legislation of 1978, for example, assigned the Fed multiple goals, including economic growth in line with the economy's potential to expand, a high level of employment and stable prices. In recent years, however, legislation has been introduced in Congress that would give the Fed a single long-run goal of price stability.
With only one policy action—that of directing the open market desk to manage the nation's money supply—the Federal Reserve is expected to aim at three targets: price stability, economic growth and full employment. But the Fed's direct influence over the long-term trends in output and employment is negligible. These trends instead depend largely on population growth, the skill and educational levels of the work force and the accumulation of capital. The only lasting contribution monetary policy can make to the real output growth trend is to create an environment conducive to growth, one in which relative prices are clear and markets are not distorted by high and variable inflation. The Fed's only power in the long-run then, lies in its ability to manage the money supply, which affects price levels.
In a market system, changes in prices help producers know what and how much to produce. Inflation affects this process by distorting the signal that prices provide. That's because it's difficult for a producer to discern whether changes in prices are due to changing supply and demand conditions or to a change in the overall level of prices. Ultimately, then, inflation distorts decisions about where to use resources, what to produce, what to consume, where to invest, what to save, what to throw away, even what to study—the fundamental decisions on which economic well-being depends. Additionally, inflation creates "shoe leather costs" as consumers and firms expend efforts and resources to attempt to beat inflation—efforts that could haven been used in a productive capacity. The monetary goal of price stability alleviates the distortions caused by inflation and contributes to a more efficient economy.
With current annual inflation rates hovering around 3 percent, the Fed is often encouraged to stop worrying about inflation and to aim for higher economic growth and lower unemployment. In a recent discussion, however, Thomas C. Melzer, president of the St. Louis Fed, stressed the value of the single goal of price stability, contending that the monetary policy that best promotes economic growth is one that prevents inflation from being a factor in the decision making of businesses and consumers. So should we be shooting for growth?"We tend to confuse short-term fluctuations in output with long-term growth," he says. This confusion can be attributed to certain conditions in which a boost in money supply can increase output For example, if people believe that the underlying inflation trend is 3 percent, but the Federal Reserve begins a series of monetary policy actions that permit money supply growth consistent with 4 percent inflation, then output growth may be temporarily stimulated. The reason is that workers and savers are "tricked" into working at a wage rate or saving at an interest rate that is too low to compensate for the upcoming inflation.
What does all of this imply about the conduction of monetary policy? Melzer explains, "Because under certain conditions monetary policy has the potential to boost output in the short run, some may be tempted to push for faster and faster growth by stepping on the monetary accelerator. Output may indeed go up for a time, but eventually inflation will be the only outcome." Thus, long-term growth is best sustained in an environment of stable prices.
To hone in on a single objective, we could apply one familiar axiom of economic efficiency—"Do what you do best." Individuals, firms and nations follow this fundamental rule in order to maximize their incomes and improve their standard of living. By the same token, monetary policy can be most credible and effective by following this simple rule and, in the Fed's case focusing on price stability as its target.
