Monetary Policy When the Nominal Short-Term Interest Rate is Zero

In an environment of low inflation, the Federal Reserve faces the possibility that it may not have provided enough monetary stimulus even though it had pushed the short-term nominal interest rate to its lower bound of zero. Assuming the nominal Treasury-bill rate had been lowered to zero, this paper considers whether further open market purchases of Treasury bills could spur aggregate demand through increases in the monetary base. Such action may be stimulative by increasing liquidity for financial intermediaries and households; by affecting expectations of the future paths of short-term interest rates, inflation, and asset prices; through distributional effects; or by stimulating bank lending through the credit channel. This paper also examines the alternative policy tools that are available to the Federal Reserve in theory, and notes the practical limitations imposed by the Federal Reserve Act. The tools the Federal Reserve has at its disposal include open market purchases of Treasury bonds and certain types of private-sector credit instruments; unsterilized and sterilized intervention in foreign exchange; lending through the discount window; and, in some circumstances, may include the use of options.

A Quantitative Exploration of the Opportunistic Approach to Disinflation

Under a conventional policy rule, a central bank adjusts its policy rate linearly according to the gap between inflation and its target, and the gap between output and its potential. Under “the opportunistic approach to disinflation” a central bank controls inflation aggressively when inflation is far from its target, but concentrates more on output stabilization when inflation is close to its target, allowing supply shocks and unforeseen fluctuations in aggregate demand to move inflation within a certain band. We use stochastic simulations of a small-scale rational expectations model to contrast the behavior of output and inflation under opportunistic and linear rules.

Monetary Policy and Price Stability

This paper explores issues that arise in implementing monetary policy under conditions of sustained price stability. We discuss several issues that concern the selection of a central banks inflation objective under such conditions: price measurement; the behavior of other key variables, particularly wages; and the possible existence of other channels through which low inflation could change relationships within the real economy. We present a framework for analyzing monetary policy reaction functions that can illuminate the choices facing policy makers in a regime of price stability. The zero lower bound on nominal interest rates is a potential constraint on monetary policy when nominal interest rates are low on average, which will tend to be the case when long-term inflation is low. We summarize the results of research done at the Federal Reserve to clarify these issues for the United States and consider the availability and effectiveness of alternative policy tools when the nominal interest rate is at the zero bound.
